The invention relates to the construction, more specifically to connecting the head to systems installation of structures for installation of structures (options).
Known connecting head and installation of constructions are used, for example, for the installation of two-story exhibition stands. Such two-story exhibition stands must, on the one hand, to be erected quickly and without problems and, on the other hand, must reliably withstand the load. Known connecting heads are supplied by the applicant under the designation DFS 250 and have hollow profile, from which the four sides depart connecting flanges. Connecting flanges are designed for use with h-beams, which are made as a hollow profiles and the lower limit of the average walls in the zone of the face side, milled. Consequently, in the zone of the end of the beam through the middle wall formed outdoor down pocket. For mounting of the beam on the connecting head last pull on top mounting flange until then, while the top shelf does not hit in the upper end of the connecting flange. Mounting flange then partially comes in a pocket on the front side of I-beams. In this position the I-beam is fixed with screws.
The objective of the invention is development of a connecting head and installation of structures that provide simple fabrication and installation.
According to the invention for this the connecting head for system installation of structures from the top and bottom ends with an average longitudinal axis connecting flange is held between the top and bottom end, and with at least one located between the upper and lower end of the connecting flange of the support surface for the seal of a beam in which mounting flange and bearing surface have a lateral offset from radial to the median longitudinal plane axis and when the base surface is parallel to the radial plane.
This embodiment of the connecting head allows to push the beam to the side of the supporting surface and yet to be located on the mid to connecting flange. Side Pogodina beams to the supporting surface can clearly simpler installation of beams, as they can be entered at the height at which they ultimately must be mounted in design. For example, the beam can be applied already lying under the ceiling. The upper end is formed, for example, the surface of the overlap overlying plate and the bottom - the bottom surface.
According to further shape the execution of the invention bearing surface connecting flange is of lateral offset by half the width of connecting end of the beam. When you connecting flange middle plane of the beam lies precisely in the radial to the median longitudinal plane axis.
In the future form of the invention provides a total of four connecting flange bearing area which are each offset by 90 degree to each other and have a lateral offset from radial to the median longitudinal plane axis.
Thus on connecting flange can be located up to four beams. Even with the four beams there is always the opportunity to take the beams to the side of the bearing surfaces of connecting flanges.
The invention also relates to the system of installation of structures with at least one the connecting head according to one of the above forms of implementation and with the beam and the beam is supplied at one end face of the reception chamber and provided located parts of the inlet chamber and parts of the speaker for the end of the beam binding element, which is attached to connect connection head to a beam on the supporting surface connecting flange.
The availability of the end of the reception chamber of the beam allows lower connecting element and in General very easy execution of the beam. For example, the beam can be made as a hollow aluminum profile. Himself binding element, which is under considerable stress from the mounting screws on the connecting flange may, in contrast, consists of a solid material. As a consequence, can be used the advantage of lightweight hollow beams without that when attaching would need to fear squeezing hollow section.
At the further implementation of the invention beam is executed as I-beams and has a height, that corresponds to the height connecting head.
Thus the end-wall of the h-beams, and covering the surface and the bottom surface of the connection head can be on the same level. Because of this created ideal conditions for the imposition of bottom plates for connecting head and beam.
Further, according to the invention height is pushed to the admissions camera on the front side of the beam connecting element less than the distance between the overlying surface and bottom surface connecting head.
So when you enter a connecting element between the overlying surface and the bottom surface of the connecting head is available a little space, so that the beam when you enter does not necessarily have to be located precisely vertically to the median longitudinal axis connecting head.
Underlying the invention problem is solved also for installation of structures with at least two beams and girders made as I-beams and are on the shelves on both sides of the wall opened to the corresponding opposite the shelf longitudinal grooves, and mounting flange made with the possibility of fixing the side of the supporting surface in two opposite longitudinal grooves, one of the beams is supplied at one end face of the reception chamber and provided situated parts in the inlet chamber and parts the speaker at the end of the beam binding element, which is made with the possibility of attachment to the side of the supporting surface connecting flange.
This creates the opportunity to connect with each other two I-beams simple way, for example, at a right angle. When connecting flange is especially simple way to be entered in two opposite longitudinal groove and fixed there. The position of the connecting flange along the longitudinal groove can be selected in any manner. Design can be planned system according to the invention highly variabelno. For mounting of the beam on the connecting flange it can be entered from the side between longitudinal grooves up until connecting the item does not fit to the supporting surface connecting flange. The height of the connecting element in his serving at the end of the beam area selected is less than the distance between the two regiments of the I-beam. With the introduction of the beam should not exactly be placed in a position at a height at which it ultimately is mounted on the connecting flange.
Further characteristics and advantages of the invention derived from the formula of the invention and of the following description of the drawings. Some indicators are presented in a variety of images form of inventions can be combined with each other without narrow the scope of this application.
The drawings show the following.

7, 8 and 9 different images installation of constructions according to further shape the execution of the invention when attaching beams.
Figure 1 shows the system according to the invention for installation of structures according to the first form of execution, and, for example, depicts the gusset obliquely front and oblique from the top. Angle connection is part of the supporting construction of the exhibition stand. Angle connection has vertical rack 10, on the upper side of which is attached connecting head 12. On the connection head in his turn attached two beams 14, respectively 16 at right angles to each other. Beams 14, 16, each as I-beams and have each middle wall of 18 and two opposite each other shelves 20, 22.
Connecting head 12 has a bottom plate 24 and overlying plate 26, which are parallel to each other and have a square shape. Bottom plate 24 fortified shown bolted to the front of the rack 10.
Between the bottom plate 24 and overlying plate 26 there are a total of four connecting flange 28, 30 and 32, each plate-like form. Fourth mounting flange 34 visible on the image of figure 2.
Connecting flanges 28, 30, 32 and 34 each made as a vertical metal plate and are parallel to not shown in figure 1, the average longitudinal axis connecting head between 12 bottom plate 24 and overlying plate 26.
Connecting flanges 28, 30, 32 and 34 are located at a distance from each other through holes that are equipped with internal thread. Already in the image of figure 1 shows that the connecting flanges, for example, connecting flange 30, and bearing surface 36 connecting flange 30 has lateral offset from radial to the median longitudinal plane axis.
Mounting flange 30 and bearing surface 36 displaced as a consequence, from the middle of the connecting head 12. It can be seen, for example, due to the fact that srini Paz 38 10 hours in the image of figure 1 does not coincide with the front edge of the connecting flange 30. Reference poverhnosti 36 is also parallel to the imaginary, radial to the median longitudinal plane axis. Thus Balka side can fit the reference surface 36 and is attached to it and yet the average plane of the beam may coincide with the average longitudinal axis podsoediniaesh head 12. Side fit beams, respectively, binder not yet described element of the beam to the supporting surface 36 connecting flange 30 yet easy to implement, as the beam must be nominated on podsoednineny head 12.
In the image in figure 1 and figure 2 shows that the beam 14 zakreplenie with a boundary that is not visible on the image to connecting flange 34 and that Balka 16 strengthened through shown in figure 2 connecting element to 40 connecting flange 32. As figure 1 and figure 2 shows that the beams 14, 16 strengthened exactly in the middle of connecting to the cylinder, 12 and that of corresponding average planes intersect exactly in the middle longitudinal axis connecting head 12.
Beams 14, 16 as hollow profiles and have within their average wall receiving chamber 42. For example beams 16 in this receiving chamber 42 parts entered binder 40 and fortified it with two screw-bolts 44. Two screw-bolts 46 are used to pin binder 40 to the supporting surface connecting flange 32 and reliably fixed binder 40 and this beam 16 on connecting head 12.
Balka 16 identical beam 14 and has an average wall, and also two opposite each other shelves 48, 50. On both sides of the wall these shelves 48, 50 have slots that open up to each shelf opposite 48, respectively 50. On the upper surfaces of shelves 48, 50 stipulated in the middle of the groove, which forms the occipital neckline.
Side view figure 3 shows the image in the gap beam 16, which on both ends are provided with connecting elements 40, 52. It is clear that the height of the mortar 40, 52 less than the total height of the beam 16 and also less than the distance between the bottom plate 24 and covering plate 26 connecting heads 12, and less than the length of the lower shelves 50 and top shelf 48 beams 16. When the beam is installed on 16 connecting head 12 it can easily vdvinut'sâ slightly tilted between the bottom plate 24 and covering plate 26 and only with the introduction of screw bolts 46 Balka 16 must take exactly the predicted position.
The image on the Fig 4 shows binder 40 in the form of front and side view. Binder 40 consists of a solid material, in General, has the shape of a plate, and in their upper and lower zones, has a wall thickness 54, 56. Wall thickness 54, 56 chosen so that they are snug against the inner walls of the reception chamber 42 and wall 54, 56 each equipped with holes for input screw bolts 44, 46. Although Balka 16 is designed as a lightweight aluminium hollow profile, mounted by linking element 40 should not be afraid of what Balka 16 may povergaetsya when tightening the screw bolts 44. System according to the invention allows the construction of lightweight and highly stable structures that can be easily assembled and dismantled. This is of particular importance when montage exhibition stands.
The image in figure 5 shows only connecting head 12. Also on the form in figure 5 shows three connecting flange 28, 30 and 32, the fourth mounting flange is hidden in the image in figure 5. Four connecting flange 28, 30, 32, 34 are angled at 90 degree each other and with side shift to radial to the median longitudinal axis 58 plane. This imaginary radial plane shown in figure 5 shaded and you can see that the support surface 36 connecting flange 30 is parallel to this imaginary radial plane 60 and has lateral displacement. As the connecting flange 30 also shifted side to this radial plane 60, beam, respectively, binder beams can side to advance towards the connecting flange 30 and is attached on it and still the average plane of the beam can match the radial plane 60 connecting head 12. Other mounting flanges 28, 32 and 34 are also with side shift to an imaginary radial plane and their support surface is parallel to a radial plane and with side shift to it. In total as a result it turns out axisymmetric to the median longitudinal axis 58 execution connecting head 12.
Another beam 66 supplied on his side of liaison 68 and can then be attached to connecting flange 62. For fixing of beams 66 on connecting flange 62, as seen in figure 7, 8 and 9, the beam is first placed obliquely to the beam 16 and then turns to a beam in the vertical 16th position. If the beam 66 took a vertical to a beam 16 position, which is visible on Fig, it is shifted downward until such time as the connecting element 68 not adjacent to its lower end to the upper edge of the bottom shelf 50. Proceeding from this position, see figure 9, beam 66 then may be imminent in parallel to the beam on 16 podzielony flange 62 up until binder 68 not attached to the side of the supporting surface connecting flange 62. In this position binder 68 can be firmly connected with the connecting element 62 with two screw-bolts.
