The invention relates to the field of building constructions, buildings and structures, namely the means of connection of rod elements of structural design with slab flooring of a roof of triangular sandwich panels. Can be used in the construction of fabric coverings.

Known nodal connection terminals of the spatial framework, in particular nodes of the connection tube and rolling rods, which can be used to create both unstrained and prestressed spatial beam structures - structures. Hub connection comprises a core with holes, consisting of two hemispheres welded to each other, coupling bolts, sheet of puconci (patent No. 2063500, IPC E 04 1/58, published 10.07.96).

The disadvantages of the known devices is the complexity of the construction site, the complexity of manufacturing and site installation directly on the construction site.

Known nodal connection of load-bearing panels of a collapsible construction of the shell for connection plate roof decking to structural design, consisting of a flat five - and three-layer hexagonal bearing panels, several sizes with corner inserts and triangular curtain panels (patent RF №2190733, IPC E 04 1/38, published 10.10.02).

The disadvantages of this device are the two who are the complexity of the installation in connection with a large number of sizes of panels, the complexity of manufacturing, application for installation of welding, which are not desirable in the construction of structural design of cleaninig pipes.

The closest technical solution to the claimed invention is a hub connection to create a continuous regular roof decking and connection with the structural design (Nuzhdin A.A. improving the efficiency of structural designs of PVC, working in conjunction with a regular deck roof: Dis... Kida. technology. Sciences / Leningrad. engineer.-builds. in T. - L., 1987. - P.76-77: ill.). Hub connection consists of a volume of the hollow element for fixing rods of the lattice, on which is rigidly fixed to the ground. In addition, the composition of the nodal connections includes a metal pressure plate. The basic platform is a square cast steel plate from the bottom bracket to surround the hollow element and the top spacers. The pressure plate is a cast steel plate with the lower spacers. Communication platform with anti-squeak plate used tie rods. By adjusting the tie rods of the panel pressed to support the platform. In this hub connection to reduce or eliminate the compliance effect is used wedge, created by Razborov.

The disadvantages of this device is Vlada great intensity, the complexity of the installation on the construction site, the need for periodic inspections during building operation uniform tension bolts slab flooring.

Typically the slab does not participate in the work of structural design, but only the load of its own weight. The inclusion of continuous slab roof decking in collaboration with the structural design will relieve the elements of the structure, to ensure greater stability, the possibility of dilution of the lattice structural design.

The problem to which the invention is directed, is to increase the bearing capacity of structural design, collaborative continuous slab flooring with structural design, simplifying the design nodal connections, simplifying installation of the structure, reducing the metal node.

The invention consists in that the hub connection continuous slab roof decking of the triangular sandwich panels with cores of structural design, including surround the hollow element for fixing rods of the lattice, on which is rigidly fixed to the ground with clamp triangular sandwich panels, three-dimensional hollow element for fastening rods triangular lattice made of solid hexagonal, truncated the one end, the ground - in the form of a circular steel plate, the circumference of which at equal distances from each other rigidly mounted U-shaped clamps for fastening the triangular three-layer flooring panels that are joined together by overlapping the top layer of plywood sheathing panel, and at all edges of panels mounted to the mounting plates of plywood, one end of each of which is mounted on the upper surface of the ribs, and the second is installed in the U-shaped clip.

The invention is illustrated by the following drawings, in which figure 1 shows a plan of the nodal connections, figure 2 is a front view of a hub connection figure 3 - section nodal connections, figure 4 - wiring diagram panel.

Continuous slab flooring are encouraged to make individual panels (starting stamps), was manufactured. To achieve nerazreznoy slab flooring joints of the ribs between the panels must be Ravnopravie material panels or close to them on the strength of the connection.

Hub connection for attaching the deck to the structural design consists of a volume of the hollow element 1 mounting tubular rods 2. A volume element on the upper surface welded steel, round base mount 3. To the frame 3 around the circumference at equal distance from each other rigidly mounted six U-shaped C which presses 4, made from metal. The clamps are made with holes 5 for installing the bolts 6. Panel 7 and 8 are made of wood, contour and contour, edges; insulation; the bottom and top of the plywood coverings. Panel 7 differs from the panel 8 is increased by the size of the upper cladding. In all the edges of the panels with plywood mounting plates 9. For fastening serving plywood sheathing panel 7 to the wooden edges of the panel 8 are used screws for wood 10.

Hub connection for attaching the decking to structural design works as follows. To surround the element 1, complete prefabricated, includes welded anchor pad 3 and the terminals 4, are attached to the tubular rod 2. In the clips installed bulk element inserted plywood lining 9 panel 8. After installation of all panels 8 are placed in your project panel in position 7. The overlap of the upper cladding panel 7 to the edges of the panel 8 is fixed by means of screws 10. Mounting pads 9 and the clamping takes place by means of bolts 6. Collaboration formed continuous slab flooring with a volume element through the clamps.

The proposed nodal connection continuous slab roof decking with rods structural design provides increased bearing capacity of the structural to the regulations, collaborative continuous slab flooring with structural design, simplifying the design nodal connections, simplifying installation of the structure, reducing the metal node.

Thanks to this technique provides a high performance, easy installation, excludes welding, the number navalnyj compounds is minimized.

Hub connection continuous slab roof decking with rods structural design, including surround the hollow element for fixing rods of the lattice, on which is rigidly fixed to the ground with clamp triangular sandwich panels, characterized in that the volume of the hollow element for fastening rods triangular lattice made of solid hexagonal, truncated at one end, the ground - in the form of a circular plate, the circumference of which at equal distances from each other rigidly mounted U-shaped clamps for fastening the triangular three-layer flooring panels that are joined together by overlapping the top layer of plywood sheathing panel, and at all edges of the panels mounted to the mounting plates of plywood, one end of each of which is mounted on the upper surface of the ribs, and the second is installed in the U-shaped clip.
