The invention relates to the construction, more particularly to a connecting head for mounting structures for mounting structures (its variants).
Known connecting head and system for mounting structures are used, for example, for mounting a two-storey exhibition stands. Such a two-storey 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 head supplied by the applicant under the designation DFS 250 and have a hollow profile, from which the four sides depart connecting flanges. Mounting flanges are designed for use with I-beams, which are designed as hollow profiles and the lower limit of the secondary walls in the area of the end faces milled. As a consequence, in the area of the end of the beam through the middle wall formed down outdoor pocket. For mounting the beam for connecting the head last pull on top of the mounting flange up until the top shelf does not hit in the upper end of the connecting flange. Mounting flange then partially comes in a pocket on the side I-beams. In this position the I-beam is fixed with screws.
The task of the image is to be placed is to develop a connecting head and system mounting structures, which provide a simple manufacture and Assembly.
According to the invention this is provided by connecting the cylinder to the system mounting structures with upper and lower ends, and the middle longitudinal axis of the connecting flange is held between the upper and lower end, and with at least one located between the upper and lower end of the connecting flange support surface for adhesion of the beam, in which the mounting flange and the support surface have a lateral offset from the radial to the Central longitudinal axis of the plane and in which the bearing surface is parallel to a radial plane.
This embodiment of the connecting head allows you to move the beam to the side of the support surface and yet not be located in the middle to the connecting flange. Side Pogodina beams to the supporting surface clearly allows easier installation of beams, as they can be entered on the altitude at which they ultimately must be mounted in design. For example, the beams can be used for laying floors. The upper end is formed, for example, the surface of the slab overlying plate and the lower end of the bottom surface.
According to a further form of execution of the invention the support surface poda digitalneho flange has a lateral offset half the width of the connecting end of the beam. When you connecting flange middle plane of the beam lies precisely in the radial to the Central longitudinal axis of the plane.
In the further form of execution of the invention provides for a total of four connecting flange support surface which are each offset by 90° to each other and have a lateral offset from the radial to the Central longitudinal axis of the plane.
Thus the connecting flange can be located up to four beams. Even with the four beams there is always the opportunity to bring the beam to the side of the bearing surfaces of the connecting flanges.
The invention relates also to a system of mounting structures with at least one connecting head according to one of the above forms of execution and with the beam, and the beam is provided on one end face of the reception chamber and being provided located parts of the receiving chamber and protruding parts at the end of the beam connecting element, which is attached to the connection head with the beam on the reference surface of the connecting flange.
The presence of the end of the reception chamber of the beam allows the lower connecting element and in General a very easy implementation of beams. For example, the beam may be designed as a hollow aluminum about the Ile. Myself connecting element, which is subjected to considerable stress from the mounting screws on the connecting flange may, in contrast, consist of solid material. Because this may be the advantage of lightweight hollow beams without that mount would need to be afraid of crushing the hollow profile.
When the further implementation of the invention the beam is performed as h-beams, and has a height that matches the height of the connecting head.
Thus the end wall I-beams and covering the surface and bottom surface of the connecting head can be on the same level. As a consequence, creates ideal preconditions for the imposition of bottom plates for connecting the cylinder and the beam.
Further according to the invention the height is pushed into the receiving chamber on the front side of the beam connecting element is less than the distance between the overlapping surface and the bottom surface of the connecting head.
So when entering a connecting element between the overlapping surface and the bottom surface of the connecting head available bit of space, so that the beam at the input does not necessarily have to be located exactly vertically to the middle longitudinal axis of the connecting head.
egawa the basis of the invention the task is solved as well by the system for the installation of structures with at least two beams, and beams made as I-beams and are on the shelves on both sides of the wall open to the respective opposite the shelf longitudinal grooves, and connecting flange configured to secure the side support surface in two opposite longitudinal grooves, and one of the beams provided on one end face of the reception chamber and provided parts located in the receiving chamber and protruding parts at the end of the beam connecting element, which is configured to mount to the side of the support surface of the connecting flange.
This creates the opportunity to connect with each other two I-beams in a simple way, for example, at a right angle. When this connecting flange may particularly simple manner, be entered in two opposite longitudinal groove and fastened there. The position of the connecting flange along the longitudinal groove can be selected in any way. Designs can be planned system according to the invention in the highest degree variabelno. For mounting the beam on the connecting flange it may be introduced laterally between the longitudinal grooves up until the connecting element is not adjacent to the supporting surface of the connecting flange. The height of the connecting element in its advocating for an end to Balk the zone is selected less than the distance between the two shelves I-beams. With the introduction of the beams must be accurately placed in position on the altitude at which it is ultimately attached on the connecting flange.
Further characteristics and advantages of the invention follow from the claims and from the following description of the drawings. Individual characteristics are presented in different images of the forms of execution of the invention can be combined with each other without narrow the scope of this application.
The drawings show the following.

7, 8 and 9 different image system for mounting structures in accordance with a further form of execution of the invention with the mounting beams.
Figure 1 shows a system according to the invention for mounting structures according to the first form of implementation of the Oia, moreover, for example, shows a corner connection obliquely from the front and obliquely from above. A gusset is a part of the supporting construction of the exhibition stand. The gusset has a vertical rack 10 on the upper end side of which is attached the connecting head 12. On the connecting head, in turn, attached two beams 14, 16 respectively at right angles to each other. Beams 14, 16 each as I-beams and each have an average wall 18 and two opposite each other shelves 20, 22 respectively.
Connecting head 12 has a bottom plate 24 and the overlying plate 26, which are parallel to each other and have a square shape. Bottom plate 24 is strengthened not shown bolted to the front side of the rack 10.
Between the bottom plate 24 and overlying the plate 26 there are a total of four connecting flange 28, 30 and 32, each plate-like form. The fourth connecting flange 34 is visible in the image in figure 2.
Connecting flanges 28, 30, 32 and 34 each made as a longitudinal metal plate and are parallel to the shown in figure 1 median longitudinal axis of the connecting head 12 between the bottom plate 24 and the overlying plate 26.
Connecting flanges 28, 30, 32 and 34 are located at a distance the one from the other through holes, which has an internal thread. Already in the image of figure 1 shows that the connecting flanges, for example, connecting the flange 30, and the abutment surface 36 of the connecting flange 30 has a lateral offset from the radial to the Central longitudinal axis of the plane.
Mounting flange 30 and bearing surface 36 is displaced as a consequence, from the middle of the connecting head 12. It can be seen, for example, due to the fact that sreni the groove 38 of the rack 10 in the image of figure 1 does not coincide with the end edge of the connecting flange 30. Reference poverhnosti 36 is also parallel to an imaginary radial to the Central longitudinal axis of the plane. In this way the beam can side against the support surface 36 and is attached to it and yet the average plane of the beam may coincide with the middle longitudinal axis of podsoediniaesh head 12. Side seal beams, respectively, the binder is not yet described element beams to the supporting surface 36 of the connecting flange 30 is thus easy to implement, as the beam must be nominated over podsoednineny head 12.
In the image in figure 1 and figure 2 it is seen that the beam 14 screeplay using a connecting element, which is not visible on the images to the connecting flange 34 and that the beam 16 is fortified with the help shown in F. the Data2 connecting element 40 to the connecting flange 32. As in figure 1, and figure 2 shows that the beams 14, 16 fortified precisely in the middle to the connecting head 12 and that of the corresponding average planes intersect exactly in the middle longitudinal axis of the connecting head 12.
Beams 14, 16 is made as a hollow profile and have inside their middle wall of the receiving chamber 42. For example, the beams 16 in this receiving chamber 42 parts entered the connecting element 40 and strengthened in it by means of two screw bolts 44. Two screw bolts 46 are used to clamp the connecting element 40 to the supporting surface connecting flange 32 and securely fasten the connecting element 40 and this beam 16 on the connecting head 12.
Beam 16 is made identical to the beam 14 and has a Central wall and two opposite each other shelves 48, 50. On both sides of the wall, these shelves 48, 50 have grooves that open each to the opposite shelf 48, 50 respectively. On the upper surfaces of the shelves 48, 50 is provided in the middle of the groove, which forms the occipital neck.
Side view figure 3 shows the image in the rupture of beam 16, which is at both ends provided with connecting elements 40, 52. You can see that the height of the connecting elements 40, 52 is less than the total height of the beam 16 and is also less than the distance between the bottom plate 24 and cover plate 26 connecting head is 12, and also less than the distance the bottom of the shelf 50 and the upper shelf 48 of the beam 16. When mounting beam 16 on the connecting head 12, it can easily vdvinut'sā slightly tilted between the bottom plate 24 and cover plate 26 and only with the introduction of screw bolts 46 beam 16 must take exactly the specified position.
Image Fig 4 shows the connecting element 40 in the front view and in side view. The connecting element 40 is made of solid material, generally has the shape of a plate and its upper and lower zones has a thickness in the wall 54, 56. The thickness of the walls 54, 56 are chosen so that they are adjacent to the inner walls of chamber 42 and the walls 54, 56 is provided with each insertion openings of the screw bolts 44, 46. Despite the fact that the beam 16 is made as light weight aluminum hollow profile, mounted by a connecting element 40 should not be afraid of beam 16 may powerstats when tightening the screw bolts 44. The system according to the invention allows the construction of lightweight and highly stable structures, which can be easily assembled and dismantled. This is of particular importance when montage exhibition stands.
The image in figure 5 shows only the connecting head 12. Also on the form in figure 5 shows three connecting flange 28, 30 and 32, the fourth podsoednineny hidden in the image in figure 5. Four connecting flange 28, 30, 32, 34 are angled at 90° to each other and with a lateral offset to the radial to the Central longitudinal axis 58 of the plane. Such an imaginary radial plane shown in figure 5 is shaded and you can see that the bearing surface 36 of the connecting flange 30 is parallel to this imaginary radial plane 60 and has lateral displacement. As the mounting flange 30 is also displaced to the side of this radial plane 60, beam, respectively, the connecting element beams can on the side to get to the connecting flange 30 attached to it and yet the average plane of the beam may correspond to a radial plane 60 connecting head 12. Other mounting flanges 28, 32 and 34 are arranged with a lateral offset to an imaginary radial plane and the reference surface is parallel to a radial plane and with a lateral offset to it. In General, as a consequence, it turns out axially to the Central longitudinal axis 58 of the execution of the connecting head 12.
Image 6 shows another connecting flange 62 according to the invention, which is provided to be inserted between the two shelves 48, 50 of the beam 16. As can be seen from Fig.7, this connecting flange 62 vdvinul St. is named the top, accordingly, the lower end in a longitudinal groove on the top shelf 48, respectively, the bottom shelf 50. In the desired position on the beam 16 connecting flange 62 is fixed due to the fact that in its upper transverse wall 64 entered the bolts that pinch on the bottom of a longitudinal groove on the top shelf 48.
Consequently, the connecting flange 62 is clamped between the two shelves 48, 50 and are kept in place without shifting.
Another beam 66 is provided at its end side of the connecting element 68 and can then be attached to the connecting flange 62. For mounting beam 66 for connecting the flange 62, as seen in Fig.7, 8 and 9, the beam is first placed obliquely to the beam 16 and then rotated to the vertical to the beam 16 position. If the beam 66 has taken vertical to the beam 16 position, which is visible on Fig, it moves down until the connecting element 68 is not adjacent to its lower end to the upper edge of the lower shelf 50. Based on this provision, see Fig.9, beam 66 can then hang parallel to the beam 16 on posetively flange 62 up until the connecting element 68 is adjacent to the side support surface of the connecting flange 62. In this position the connecting element 68 can be firmly connected with the connecting element 62 by means of two screw bolts.
