Group of inventions relates to the field of construction, in particular to methods perform plastering and other works on the construction of the walls, using a beacon profiles.

A known method of manufacturing a wall surface by drawing on the canvas walls of the working mixture, pressing it a beacon profiles, re-drawing on the canvas walls of the working mixture to obtain a layer with a thickness exceeding the height of the lighthouse profiles, and smoothing the surface of the wall using rules, moving on the exposed parts of the designed profile (Astakhov GI and other Plaster work. M: Gastrolyzer, 1957, p.85, 86).

Used to implement the method designed profile does not allow for strict verticality of the walls and its smooth surface, because the pressure from the rules it can be pressed into the working mixture in an uncontrolled depth and SAG in places irregularities on the base of the wall. In addition, the thickness of the finished plaster layer is determined by the height of used beacon profile, if necessary, to comply with different requirements for plaster (simple, advanced, highest quality) requires a set of beacon profiles of different heights.

The objective of the invention is the provision of high-quality surface of the walls.

The technical result is subramania is providing the required rigidity lighthouse profiles when installing them on the wall in places irregularities on the base wall, ensuring the verticality of the finished walls and the possibility of obtaining a layer of the working mixture of the desired thickness.

The technical result is achieved in that in the method of manufacturing a wall surface by drawing on the canvas walls of the working mixture, pressing it a lighthouse beam profiles with a spacing not exceeding the length of the rules, re-drawing on the canvas walls of the working mixture to obtain a layer thickness exceeding the height of a lighthouse beam profiles, and smoothing the surface of the wall using rules, slipped over the protruding part of the beacon beam profile according to the invention using a beacon profiled beams installed them along the adjusting screws so that the screws were placed, including in places of roughness on the base of the wall, after pressing a lighthouse beam profiles in the working mixture nominate adjustment screws all the way to the base of the wall in such a way that it is provided with the vertical position of the beacon beam profiles, the required thickness of the layer of the mixture.

If necessary, in areas of unevenness of the Foundation wall adjustment screws, it is advisable to install in smaller increments than on a flat surface.

The technical result is also achieved by the fact that a lighthouse beam profile for making the surface of the wall contains the longitudinal supporting member, United with him two perforated side walls with the waste from them in the opposite side of the perforated bases, the edge of each base plate is curved with the formation of longitudinal triangular protrusion, the first face which is perpendicular to the main part of the base, the second parallel part, and the third at the line forms with the second face angle of at least 90°.

In addition, the angle formed by the second and third faces of the base, preferably equal to 135°.

The holes of the perforated side walls and bases can be located on the fold line of the side wall of the base, so that one part of the area of each hole is on the side wall and the other on the ground, with the line of fold of the side wall of the base passes through the centers of these holes, which may be round, or oval, or other shape.

The beam may be provided with longitudinal guide insert located in the recess of the longitudinal support member and having a convex working surface in cross section.

In another embodiment, the walls of the recesses of the longitudinal support member can be tapered with the formation of ribs on the inner side of the longitudinal support member.

The invention is illustrated by drawings.

Figure 1 and figure 2 shows the scheme set the Cai beacon beam profile on the basis of the wall, with the deviation from verticality; figure 3 - installation beacon profile based on the wall with uneven; figs.4-6 - embodiments of the beacon beam profiles; figure 7 - arrangement of the holes for the adjustment screws on a steel workpiece; Fig - the location of the perforation holes on the fold side wall of the base.

A method of manufacturing a surface of the wall is implemented as follows (Fig.1-3).

On the basis of 1 wall, requiring finishing (plaster), put sculpts every ˜30 cm dissolved mixture. In her press beacon profiles 2 in the vertical direction increments not exceeding the length of the rules is a tool for leveling the mixture.

For the proposed method uses a lighthouse beam profile (profiles) 2, in which the length is set in the holes of the adjusting screws 3. When installing a lighthouse profiles 2 their position aligned with the vertical plumb and fix them by means of the adjusting screws 3 that screw all the way into the base 1 wall. At the same time by means of screws 3 set the required thickness of the plaster layer. In places of roughness based on 1 wall (Fig 3) installation is screwed to lock the adjusting screws 3 provides rigidity lighthouse profiles 2 when pressed on them the rules that, in turn,provides a smooth wall surface.

If necessary in places of roughness adjustment screws 3 can be installed in smaller increments than on a flat surface. This is ensured by the fact that a beacon profiles 2 perform fine-pitch screw holes 3, and the 3 screws placed in each hole and through one, or two, or more, and in places irregularities that require high stiffness, set in available openings extra screws 3.

After curing, the mortar mixture and, consequently, the fixing position of the beacon profiles on the wall from the bottom up put the working solution layer exceeds the thickness of the height of a lighthouse profiles with screws.

Once applied to the wall working solution starts to settle (approximately 3-5 minutes), the surface of the wall align with the rules, moving on the exposed parts of the lighthouse profiles, removing the excess plaster, fill all irregularities (indentations) on the basis of the wall.

The proposed method can be implemented using a beacon beam profile the following syntax.

A lighthouse beam profile 2 profile contains supporting member 4 and United with him two perforated side walls 5 extending from them to the opposite side of the perforated bases 6. The free edges of the bases 6 are curved with the formation of prodol the CSOs triangular protrusion 7 (bend). The first face of the protrusion 7 is perpendicular to the main portion 8 of the base 6, the second parallel part, and the third at the line forms a second obtuse angle, preferably 135°. The third edge face preferably lies in the same plane with the main part 8 of the base 6.

On the main part 8 of the base 6 is placed holes 9 under adjustment screws 3. Curves 7 give reasons 6 beams for rigidity.

Curves 7 provide education additional internal cavity under beam height h of the working mixture, ensuring increased adhesion profile of the beam with the material of the fill.

Two symmetric to the extreme edges of the flexure 7, placed at an angle of 135 degrees, increase the stiffness of the beam.

The beam is equipped with a plastic adjusting screws 3 are inserted into the holes 9 of the base 6 of the beam, to provide the adjustment necessary level beams, horizontal to the floor level, the verticality of walls, thickness of the layer of the mixture.

A lighthouse beam profile is made from a flat steel blank 10 for forming mills to ensure strict symmetry of the cross-sectional beam profile and straightness in the longitudinal direction.

Pre-perforation steel billet provides the location of two symmetric groups open the th 9 and 11 under adjustment screws and under the valve and to pass the mixture, the latter are arranged in such a way that passes through the centers of the bend line "side wall - base".

The location of the holes 11 facilitates and accelerates the filling of the internal cavity of the profile beams with concrete or other working mixture due to the position of one part of the hole 11 on the side wall 5 of the beam, and the second part is based on the 6 beams.

Holes 11 may be round or oval or any other configuration.

In the first embodiment, the longitudinal supporting member 4 is made with a longitudinal recess (trench) 12 (figure 4).

In another embodiment (figure 5) beam profile with longitudinal guide plastic insert 13 is placed in the groove 12 beams having different cross-sectional shape, for example the shape of a truncated vertical plane or the amount of "dovetail". The same form have the top and bottom of the insert 13. The plastic insert 13 allows you to increase the height profile of the beam.

In the third embodiment (6) wall of the gutter rolled up, so they form a rib 14 of the stiffener on the longitudinal support element 4 of the profile.

Holes 9 under adjustment screws made round with a groove in the area of the edge of the hole. The edges of the groove are angled in opposite directions with the formation of helices for entry into the thread of the screw (6).

Holes 9 under the reg is inovaciniu screws (7) on the basis of 6 profile beacon beams are stamped with the selected step (20-30 mm) symmetrically with respect to the side walls of the profile, but with the slots facing in opposite directions. This scheme forging steel billets under the profile leads to the fact that the speakers are "down" relative to the plane of the workpiece of the semicircle get the screw holes 9 under the adjusting screws are located symmetrically relative to the longitudinal axis of the workpiece under the profile.

This enables you to use when getting on a roll forming mill steel perforated workpiece profile required cross-section is symmetrical to the axis profiling (the axis of the workpiece) of the calibration tool, which leads to stability of the profiling process and ensures the accuracy of the geometric dimensions of the steel profile in both longitudinal and transverse directions.

Hole 9, outperformance on the ground plane 6 and is not engaged by adjusting screws 3 on the one hand, at the indentation in the solution caused by the sculpts for fastening of profile 1 mortar, squeezed out the excess mortar to the outside, thereby ensuring that the desired depth profile, and on the other hand, provide ingress into the internal cavity of a lighthouse beam profile plaster or other compounds, improving thereby the adhesion of a lighthouse beam profile obtained with nivelirnoj surface.

Cu is glue or oval holes 11, outperformance bend line base and side wall of steel profile beacon beam profile, in addition to facilitate ingress into the internal cavity of the steel profile of the working mixture was allowed in the case of technological necessity to reinforce the cards fill wire armature.

The bends 8 of the base 6 steel profile profile beacon beams, on the one hand, improve the fixation of the profile when the indentation in securing the mortar mixture, and on the other hand, form an additional internal cavity that is filled with the working mixture, which improves the adhesion with the base of a lighthouse beam profile obtained with layer nivelirnoj surface.

The proposed construction of a lighthouse beam profile allows using the same steel profile is the main structural element, obtained by using the adjustment screws of different thickness of the plaster layers.

The proposed construction of a lighthouse beam profile allows for the manufacturing of the basic element of the design of cold-formed steel profile billet of steel economical thicknesses of 0.5-0,80 mm Bending steel profile under the influence of rules or other razravnivaya device on the ground of possible voids in the Foundation wall shall be prevented by installation of these places additional plastic, regulirovat what's screws (minimum installation step adjustment screws - 20 mm).

Partitions are located between carrying profile posts and extend transversely to the posts. The partitions are made as posts of carrying profile having H-shaped cross-section and located between the posts. Posts of H-shaped carrying profile are defined by flanges and post of thrust profiles having U-shaped cross sections connecting the flanges. The thrust profiles face cladding panels by opened cavities thereof. Free end of each flange defined by thrust profile cross-section is bent inside the cavity so that acute angle is created in-between. Extensions of longitudinal mounting profile ridges are arranged between trust profile bends. The mounting profile has longitudinal extensions. Mounting profile strip touches free end of each mounting profile flange at bends. Longitudinal extension of face side ribs are directed one towards another. Adjacent cladding panels create cladding panel fixing profile at joint between grooves thereof in which longitudinal mounting profile rib extension are inserted.

EFFECT: simplified facing structure, increased manufacturability, reduced labor inputs for facing structure assemblage, prevention of panels to be connected misalignment.
