The invention relates to a structure for maintaining a uniform surface temperature, containing a supporting layer for fixing the line to maintain a uniform temperature.

Such constructions are used, for example, when the floor heating. For example, from DE 202005002322 U1 known design for floor heating, in which the bearing layer is made in the form of stacked plate has a U-shaped groove, which can be laid line to maintain a uniform temperature, in this case, for example, the heating line. To lock in the slot specified line offered two options.

On the one hand, it is proposed to fill the groove with putty placed in it a line to maintain a uniform temperature. For better fixation putty groove near its mouth on the opposite side has grooves with which the plaster may hook after hardening.

On the other hand, proposed to narrow the mouth of the groove in predetermined locations along its length, so that in the transverse direction it is slightly inferior to the diameter of the line to maintain a uniform temperature. In this case, the specified line in the narrowed locations is pressed into the grooves, with its fixation in the groove is carried out by the stops.

A disadvantage of the known floor construction is the possibility of damaging the line indentation in a groove in the European the different places. In addition, there is no guarantee pressure lines to maintain a uniform temperature to the bottom of the groove, which when filled with putty can lead to the formation of cavities below the line. These cavities can be broken high point load putty, for example rollers chair that can cause damage to the line. In addition, to ensure reliable fixation line of the required high precision of the groove, i.e. with minimal tolerances. It is expensive and time-consuming. In particular, the mechanical wear of the cutters, which, for example, are used for making grooves, constantly results in narrowed groove that can significantly complicate the placement of the notch line to maintain uniform temperature and increases the likelihood of damage. Replace worn cutters and their recovery cost.

On this basis the basis of this invention is the task of developing the design to maintain a uniform surface temperature, which can eliminate the disadvantages of the known technical solutions. In particular, should be the design to maintain a uniform surface temperature, which enables a particularly simple and reliable fixation of the line to maintain a uniform temperature. In addition, it should be developed building ele is UNT, containing the design to maintain a uniform surface temperature.

This problem is solved by the characteristics items 1 and 18 of the claims. Embodiments of the invention follow from PP-17 claims.

According to the first aspect of the invention proposed design for maintaining a uniform surface temperature (design to create surfaces artificial climate indoors or device for maintaining a uniform surface temperature), which has a supporting layer having a groove extending from the surface of the layer depth. The groove serves for placing the line to maintain a uniform temperature (also called line for thermal environment or line supports temperature environment, for example the line for the heating and/or cooling medium) and has several sections that are offset relative to each other and/or rotated axes, following each other directly or through transitional areas.

In the present invention the term "temperature" is understood to mean, in particular, a collective in the sense that as a result of maintaining a uniform surface temperature may occur heating or cooling. Thus, the invention together with the structure for heating the surface also includes design is to cool the surface, as well as the design, which can perform both heating and cooling, depending on the environment, supporting a uniform temperature. In accordance with this line to maintain a uniform temperature may be in line for the heating and/or cooling medium.

According to a preferred variant of execution for fixing the line to maintain a uniform temperature of at least one lateral side of the groove at least at specified places on sections of the groove and/or transition areas between consecutive sections of the groove at least partially performed with undercutting. When the undercut is made in such a way that the groove respectively continuously narrows his mouth or neck in at least one area between the bottom and the mouth or throat.

Line to maintain a uniform temperature is made, usually elastic or flexible. The offset of the axes of the groove or by placing them at an angle relative to each other provided reliable fixation line when installed in the groove using the undercut.

Held in the groove curved line to maintain a uniform temperature due to its elasticity is pressed to the sides of the groove in a direction parallel to the supporting layer. Because the groove is narrowed to his mouth, Lin is I to maintain a uniform temperature, it is pressed in the direction of the bottom of the groove. Thanks to this reliable fixation of the line in the groove can be provided without filling the groove with a filler, etc. in Addition, in contrast to the known technical solutions at the mouth of the groove does not need any additional tools for fixing line with the clamping. Thus, when inserted into the groove to prevent damage to the clamping, etc. lines to maintain a uniform temperature.

If the sides of the groove are undercut at least in those places where the line to maintain a uniform temperature due to its elasticity pressed to the side, this line can be very easily fixed without additional safety measures.

With proper execution of the undercut line can always be pushed to the bottom of the groove, which prevents its ascent when filling the groove with a filler and helps prevent under her cavities.

The proposed design can be a part of a device for maintaining a uniform surface temperature, embedded in the floor, wall and/or ceiling of the building. In this case, the temperature maintenance means, in particular, cooling or heating of these surfaces. In this respect, the proposed design can, in particular, to be a part of the heating of a floor, wall or ceiling. Depending on the purpose of PR is changing through the line to maintain a uniform temperature may be omitted or pumped more hot or more cold compared to the ambient temperature of thermal environment (or maintaining temperature Wednesday, coolant, such as heating and/or cooling medium). The proposed design is equally suitable for all types of floors, walls and ceilings, in particular for hollow or double floors, walls or ceilings.

For stabilization and protection line to maintain a uniform temperature, the volume of the groove not occupied this line may be filled with a hardening filler. To enable complete filling is mainly used fluid filler.

Using groove made according to the invention, can be achieved constant pressure line to maintain a uniform temperature to the bottom of the groove. Consequently, it is possible to avoid the formation of voids after curing of the filler, which adversely affect the point load capacity. Sometimes to fill the groove is suitable also suitable fine-grained dry filler, preferably solidified.

The particular advantage is that, thanks to the groove, continuously tapering to his mouth, the line to maintain a uniform temperature, regardless of its diameter, is essentially uniformly pressed against the bottom of the groove. In particular, this allows the mouth of the groove is wider than the diameter of the line. Therefore, the groove can be made with relatively large tolerances. Due to this the th mechanical wear of the milling tools in the manufacture of groove cutting, which can lead to complications in the known systems, is much less significant.

The grooves of the same shape made according to the invention, likewise in a certain range can be suitable to accommodate lines of different diameters.

The particular advantage in the manufacture of groove cutting milling tool is running both sides of the groove with undercut so that the groove in at least one region between its bottom and the mouth, continuously narrows on both sides in the direction from his plate to his mouth. In this case, the groove can be produced by a single milling tool, such as end mills, and within a single operation.

In relation to the particular shape of the groove, i.e. in particular in relation to displaced relative to each other and/or angled axis of the groove, there are several forms essentially equally suitable. For example, the shape of the groove in a plane parallel to the supporting layer may be serrated, wavy, meander and/or zigzag. For making grooves by means of milling is particularly suitable wave-like or meander shape of the groove, as such shapes can be formed in the bearing layer with a relatively low cost. The use of wave-like or meander scrollend the x forms allows to avoid formation in the groove of the transverse edges. Such transverse edges while pressing the line to maintain a uniform temperature to the sides can cause damage such as kinks.

If the groove milled in one technological operation, both sides of the groove, as a rule, are formed with undercut according to the invention. However, the sides can be formed with depressed only in those areas which form the lateral sides with respect to the axis of the groove is characterized by a negative radius or negative radius of curvature. In such places it is laid in the groove of the flexible line to maintain a uniform temperature due to its elasticity, as a rule, is pressed in the direction of the undercut, however due to the special structure of the undercut in turn provided with the pressing of this line towards the bottom of the groove.

Macrogeometry groove or at least a large cohesive section of the groove may have a different implementation. Under macrogeometry understand the shape of the groove without taking into account the exact geometric shape of the plots of the groove and transitional areas. For example, the groove may pass through the bearing layer essentially linearly. Can also be used spiral shape and form one or more loops or bends. In the case of the linear macrogeometry or macrogeometry with loops or bending the mi the groove may have along its length the first few areas of the groove, preferably parallel to each other, which respectively made several sections of the groove and transition sections. For loops or bends, the first region of the groove can be connected to each other curvilinear second regions of the groove. From the above it is clear that macrogeometry groove varies widely, with sustaining gains, and can be coordinated with other requirements, for example with the desired surface density of lines to maintain a uniform temperature.

Supporting layer may be made of any material suitable for the construction of base layer structures to maintain a uniform temperature in floors, walls or ceilings. In particular, suitable hardening construction materials such as concrete, material for monolithic floors, etc. may Also be used such materials as plaster, in particular gipsovolokonnye mixture, anhydrite, wood, in particular solid wood, shavings, pulp wood, laminated wood and plastic and/or hard foam. This base layer may contain one or more plates of the base layer, connected or coupled to each other.

The second aspect of the invention relates to the construction element, in particular to a prefabricated construction element, the soda is containing a floor element, wall or ceiling together with the design to maintain a uniform surface temperature according to the first aspect of the invention. Advantages and beneficial effects for the second aspect of the invention derive from the advantages and beneficial effects of the first aspect of the invention. In particular, can be achieved firm fixation of the line in the groove without additional measures. This result may equally be achieved, taking into account height and maximum width of the groove, for lines to maintain a uniform temperature of various diameters. In addition, the groove is proposed according to the invention, allows displacement of the slots on the transition between adjacent prefabricated construction elements. This reduces the cost of positioning, if the design is to maintain a uniform surface temperature collected from individual bearing plates.

The invention is illustrated further more through description of the variants of its implementation with reference to the accompanying drawings. Pictured:

figure 1 is a top view of the design for floor heating systems, as an example of the structure for maintaining a uniform surface temperature according to the invention,

figure 2 - cross section design for floor heating systems according to Fig 1,

figure 3 is a top view of a magnified portion of the groove structure for heating the Ola according to figure 1,

Fig 4a,b - the following cross-sectional design for floor heating systems,

5 is a top view of a variant design for floor heating systems.

Identical or functionally identical elements are indicated on the drawings with the same number of positions. The invention is further explained with the help of designs for floor heating. It should be noted that the following description could be transferred to other structures to maintain a uniform surface temperature, for example design to maintain a uniform temperature of the wall or ceiling, in particular the structure for heating the wall or ceiling.

Figure 1 shows a top view of the structure 1 for floor heating. Design 1 contains supporting layer 2, which in this embodiment has a total of three of the groove 3. Each groove 3 passes from those shown in the top view of the surface 4 of the carrier layer 2 into the base layer, which can be seen in cross section in figure 2. The grooves 3 are designed so that they can be placed in line 5 to maintain a uniform temperature, for example a heating line, as shown in detail in the zoomed image of the groove 3 on 3. Laid in the groove 3 line 5 shown in phantom lines. It is shown that the line shape is approximate, line 5 may also be straight or at measures is almost rectilinearly, that however is not mandatory. Preferred may be a small offset of the axes, for example approximately 2 mm, because due to this pressure to the walls of the groove can be obtained the best fit.

Each groove 3, when viewed from above, has a wave-like or meander shape, as can be seen from figure 1. Due to the wave-like or meander shaped groove 3 has along its length several adjacent parcels 6, the shaft 7 which are located at an angle to each other.

From figure 2 in combination with figa understandable particular cross-sectional shape of the groove 3. In an embodiment according to figure 2 and figa the groove 3 has a pear-shaped cross-section. The groove 3 has a bottom 8, the adjacent side walls 9, which in the upper part of the groove 3 is fixed in the neck 10 of the groove, and the mouth 11, located in the end cap 10 on the surface 4. In the area of the neck 10, the sides 9 are vertically downwards, and in the area adjacent to it, made with the undercut 12. The undercut 12 near the bottom 8 is rounded in the form of a circular arc section, which forms a bulge. The bulge goes in passing obliquely upwards plot, continuously tapering to the neck 10.

Therefore, the sides 9 are partially completed with the undercut 12 in such a way that the groove 3 in the area between the bottom 8 and the mouth 1 continuously tapers to the neck 10 or mouth 11.

Using designed in such a way that the groove 3 line 5 can reliably and without additional measures to stay in the groove, which further details shown in figure 3, figa and fig.4b.

Figure 3 shows an enlarged section of the groove 3, in which is placed a flexible line 5. The mouth 11 shown in solid lines, and the undercut 12 indicated by the dotted lines. Due to the wavy shape of the groove 3 provided with the pressure line 5 due to it returning to the elastic forces in some parts of the groove 3 in the direction of the lateral sides 9. Due to the undercut 12, continuously tapering to the neck 10, line 5 due to the elastic forces also pressed against the bottom 8. Thus, line 5 is pressed and depressed 12, and the bottom 8, as can be seen from figa.

The location of a parcel in which line 5 is pressed to the sides 9, depends on the appropriate form of the groove 3. In this embodiment, these areas are in relation to the relevant local axes 7 a negative radius of curvature, i.e. are concave in relation to the relevant local axis 7. In this regard, you can specify that in principle the undercut 12 is sufficient to perform only these concave sections.

On fig.4b as an example, shows an alternative form of the undercut 12. The undercut 12 right side 9 conforms to the shape of a rounded undercut 12 is described with reference to figure 2 and figa, but in contrast it made with the corners. Analysis of the drawing fig.4b shows that this form is suitable and allows to obtain the same favorable results. The same results can be obtained by using the groove with other cross sections, in geometry which takes into account the purpose of the groove described above. For example, the cross-section of the groove may have a dovetail or bottles. Also of note is the possible cross-section of the groove with a funnel-shaped or have the shape of a truncated cone depressed, with the largest mouth of the funnel or the greatest bottom surface of the truncated cone can be terminated directly on the bottom of the groove or at a distance from him. In the latter case, the distance between the cone or truncated cone and the bottom of the groove may be blocked, for example, a vertical wall.

By providing secure fixation line 5 in the groove without additional measures the width of the mouth 11 may be larger than the diameter of the line 5. This way can be provided with particularly simple laying of the line 5 into the groove 3, and thus it is possible to avoid damage to lines 5 when installed in the groove 3. The latter may occur, for example, known in the grooves in which to fix the line 5 in the groove 3, the width of the mouth of the groove at specified places narrowed or made smaller than the diameter of whether the AI.

As shown in figa, volume 3 groove not occupied by the line 5 filled with a hardening filler, for example putty, etc. Filler in the General case can be organic or inorganic materials, and organic and Neorganicheskie related composite materials. The filler acts in a stabilizing manner that provides additional support to line 5 and at the same time protects it from external influences. In addition, the filler can improve the heat transfer.

Shown in figure 1, the grooves 3 are held between the opposite sides of the base layer 2, and macrogeometry each groove 3 is essentially linear. Under macrogeometry should understand the shape of the groove 3 without regard to its exact geometric shape, in this case the wave. Possible other forms of macrogeometry. For example, at least in some areas this form can be coiled or set loops or bends. Macrogeometry can also be characterized, for example, a sine or cosine plots or plots, curved like the spline lines. Forms with the same curvature enable easy styling line 5.

Form loops shown in variant designs for floor heating figure 5. Here, the groove 3 has along its length a total of three first region 13, linearly flowing essentially parallel to each other. Region 13 are connected to each other curvilinear second regions 14, so that in General macrogeometry groove 3 is characterized by bends or loops. The number of loops may differ from the number of loops figure 5 and can be selected in accordance with the relevant requirements, such as the surface density of the line to maintain a uniform temperature or a heating line. Especially suitable are microgeometrical forms in which the transition from the curved region of the groove in the linear region of the groove is made on a tangent, i.e. the linear region of the groove is similar to the tangent to the circle with the radius of the curved region of the groove in the transition region.

In the first area 13, similar to figure 1, respectively, there are a few lying one behind the other sections 6, which are connected to each other transitional areas 15. Sections 6 figure 5 have the axis 7, in contrast to figure 1, located at an angle relative to each other and offset from each other relative to the longitudinal direction of the groove 3. As shown in phantom lines, the sides 9 of the groove 3 are at least in the first areas 13 of the undercut 12, which is formed as described above.

In this embodiment, the offset axis 7 can be firmly secured in the groove 3 line to maintain a uniform temperature. If this is during the execution of the groove corresponding to the cross-section it is possible to achieve the same effect, as at the location of the axis 7 at an angle according to figure 1, i.e. what is laid into the groove line 5 due to its elasticity is pressed in the appropriate places to polnotsennym 12 and in the direction of the bottom 8 and thereby securely in the groove 3 without additional measures. In addition, in this embodiment and in the embodiment according to figure 1 and figure 3, you can choose the width of the mouth 11 and the depth of the undercut 12 in such a way that reliable fixation line 5 is achieved by one only of the geometry of the groove 3. This is shown in the example, the first region 13 located on figure 5 below. The offset of the axes 7, corresponding to the location of the axis 7 at an angle in figure 1, leads to the fact that the first width B1 mouth to set the line 5 into the groove 3 is larger than the second width B2 of the mouth along the length of the first region 13. If the first width B1 is greater, and the second width B2 is smaller than the diameter of the line 5, line 5, repeating linear macrogeometry first area 13, can not go out of the groove 3. It should be noted that with proper execution of the groove 3 due to the elastic line 5 here it is also possible to provide a force directed to the bottom 8. As already mentioned, due to such force effects can be avoided floating line 5 when filling the groove 3 filler and the formation of cavities below the line 5.

Should indicate that the proposed out what rutenium also covered by the combination of the two presented options, i.e. the combination of offset and angled axes 7.

The groove 3 and its shape is described in more detail with reference to figa. It should be noted, as described below, the geometry of the cross section of the groove 3 are equally suitable for lines 5 different diameters, for example in the range from 10 to 20 mm, in particular from 14 to 17 mm This is explained including the combination according to the invention the accurate geometry, i.e. the location angle and/or offset of the axes 7, and a specific form of the undercut 12.

For example, the diameter of the line 5 in the range from 10 to 20 mm, in particular from 14 to 17 mm, 3 groove may have a depth of about 25 mm, and the width of the mouth 11 may be approximately 19 mm In the case when both lateral sides 9 have the undercut 12, the maximum width in the region of the undercut 12 may be approximately 29 mm, it is shown on figa curvilinear transition between the bottom 8 and the tapering section of the undercut 12 may have a radius of curvature of about 7 mm, and the transition between the tapering portion and a neck 10 may have a radius of curvature of approximately 1 mm Tapering area of the undercut 12 may form with the plane of the mouth of the groove 3, the angle is about 55°. As already mentioned, the groove 3, is made in accordance with the above dimensions, equally suitable for lines 5 diameters in the range from 14 to 17 mm, So the manufacturing of the groove 3 is connected is less stringent requirements in relation to size tolerances. This simplifies manufacture and, in addition, leads to cost reduction in the manufacture of the groove 3.

The groove 3 can be made in several ways, the choice of which depends in part upon the material of the base layer 2. Such materials can be used in all building materials, suitable for manufacturing floor elements, wall or ceiling, in particular materials with good thermal conductivity, such as hardening of construction materials such as concrete and material for monolithic floors, gypsum, in particular gipsovolokonnye mixture, anhydrite, wood, in particular solid wood, shavings, pulp wood, laminated wood and plastic and/or hard foam.

The groove 3 may be formed simultaneously with the manufacture of the construction element of a floor, wall or ceiling. This way you can prepare for prefabricated construction elements, such as slabs for paving, etc. that can be placed on the building site and relatively quickly fitted lines 5.

It is also possible the formation of the grooves 3 at the construction site after the production of the base layer 2. This supporting layer 2 can be constructed, for example, by connecting the bearing plates like cladding tiles. The grooves 3 may be formed either after the construction of only the base layer 2, i.e. after laying all required essig plates, or sequentially for one or more bearing plates in the construction of the base layer 2. It is also possible implementation of the invention in the old monolithic floors by performing them in the appropriate slots.

Methods of milling, in which the grooves 3 are automatically or manually milled in the bearing layer 2, or in the carrier plate, by means of a milling device with the upper cutter, suitable, in particular, not only for the formation of the grooves 3 at the construction site. When milling can be applied cutters, in particular, end mills, which are made in accordance with the size of the groove 3, so that the grooves 3 can, for example, be formed within one technological milling operations. The advantage of making the grooves 3 at the construction site is in a particularly high flexibility in relation to spontaneous changes or approvals form of a groove. To perform groove milling device is carried out from the end faces of the bearing layer 2 or the start of the recesses in the bearing layer 2 parallel to its surface 4, thus by proper conduct of the milling device is formed a groove of the desired shape. For example, by means of serrated, wavy, meander and/or zigzag conduct milling device generates a corresponding serrated, wavy, m is androva and/or zigzag shape of the groove.

If the pipe must be entered in the supporting layer or the entire construction element, or derived from, the implementation of this mill in the manufacture of the groove can be carried out with depth and simultaneous formation of macrogeometry, for example wave form. Formed by this groove prevents lifting of the line to maintain a uniform temperature from the groove on the upper side of the base layer, or construction item. When the depth of the cutter is running helix 180°.

From the description of the embodiments, in particular, it is clear that by using the design to maintain a uniform surface temperature according to the invention is particularly simple and reliable fixation of the line to maintain a uniform temperature. In addition, can be achieved fast and nevertheless high-quality laying these lines at relatively low production costs. In particular, it is possible to avoid damage to such lines when installed in the slots.

SUBSTANCE: isolation building form structure includes form sized to erect one concrete wall section. Form comprises the first elongated side panel of foamed polystyrene and the second elongated side panel of foamed polystyrene. Each panel has top and bottom, wherein panel bottom serves as building wall bottom and panel top is building wall top. Form comprises elongated horizontally spaced vertical dividers of foamed polystyrene having at least four sides and arranged between panels. Dividers serve as spacing bars and define spaced channels for concrete pouring between dividers. Dividers have upper and lower ends. Upper divider ends are spaced downwardly from upper ends of panels, lower ends thereof are spaced upwardly lower ends of panels to form upper and lower areas for concrete pouring. Upper and lower areas communicate with channels between dividers. Dividers have uniform cross-sections along the full length thereof so that concrete to be poured in channels form concrete columns having constant dimension in vertical direction. Each column has four vertical sides arranged at an angle one to another so that medium parts of concrete posts are wider than side parts thereof, which results in decreased width of divider centers for decreasing dividers compression between panels under the action of compression force applied thereto.
