Description

The present invention relates to the field of construction and is intended for the device of prefabricated monolithic joints of wall panels with openings and ceilings in panel and panel-frame residential, civil, industrial and other buildings and structures.

Known platform joint supporting wall panels on hollow core slabs (see the manual for the design of residential buildings / Central Research Institute of Housing of the State Committee for Architecture. Issue 3. Designs of residential buildings (to SNiP 2.08.01-85). -M .: Stroyizdat, 1989, - Fig. 18, d, p. 46), including the lower monolithic panel, hollow core slabs with reinforced ends and the upper monolithic panel supported on them, as well as concrete monolithing between the ends of the hollow core slabs reinforced with a frame.

The disadvantage of this design solution is that in the case of the device in the underlying panel of the wall of large openings, the bearing capacity of the joint is not provided. The disadvantage of this constructive solution is also that in the joint there is no monolithic structural connection between the concrete monolithic and the lower wall panel.

A platform joint is also known (see Pat. 2276712 Russian Federation, IPC E04B 1/61, E04B 5/02. Platform precast-monolithic joint / V.I. Kolchunov, V.N. Petrov, N.V. Klyueva, E. A. Meleshkova .-- No. 2005100242/03, declared January 11, 2005, published May 20, 2006, Bull. No. 14. - 5 pp.), Including multi-hollow floor slabs supported on internal load-bearing wall panels, in the voids of floor slabs, facing the end of the slab, at a distance exceeding the thickness of the panel, concrete diaphragms with a thickness of at least 30 mm are arranged, at the same end along the edge in the upper thin part of the slab above the voids are made holes are planed into the depth to the depth from the upper surface of the slab to the void, the section between the end of the floor slab and the diaphragm is reinforced with a vertical frame and filled with concrete, in the upper part of the monolithic joint, the reinforcing mesh is additionally laid on the entire width of the monolithic section, which has rectangular projections in the plan, overlapping these monolithic sections in rectangular holes arranged at the ends of the plate above the voids.

The disadvantage of this design solution is that such a joint, due to the lack of reinforcing outflow from the underlying wall panel, also does not provide a rigid connection between the concrete reinforcement and in the presence of a large opening in the lower panel, and as a result, the bearing capacity of the platform is not provided in such a joint joint, in addition, with this design of the platform joint, the overall spatial rigidity of the building with a high number of floors is significantly reduced, especially if there is a wall s panel openings of large size, which greatly reduces the spatial rigidity of the high-rise buildings and the vitality of the entire structural system of this type, especially in the case of openings in the wall panels.

The technical problem to which the invention is directed is to provide the bearing capacity of the platform joint formed by wall panels and floor panels and to provide the possibility of installing large apertures in wall panels, as well as to improve the manufacturability of the platform joint.

This is achieved by the fact that in the platform precast-monolithic joint, including multi-hollow floor slabs, supported on internal load-bearing wall panels, in the voids of the floor slabs facing the end of the slab, at a distance exceeding the thickness of the panel, concrete diaphragms with a thickness of at least 30 mm are arranged, in the same end along the edge in the upper thin part of the slab above the voids are made rectangular holes in depth from the top surface of the slab to the void, unlike the prototype wall panels have large openings and their vertices The hiding zone above the cutout is reinforced with an additional frame with outlets from the plane of the upper face of the panel, on which the floor slabs are supported, and a reinforced monolithic belt is arranged in the space between the ends of the plates, the reinforcement of which is connected to the outlets from the upper face of the panel and to the vertical working rods of the upstream panel and embedded parts with centering rods mounted in the corresponding centering grooves of an upstream wall panel are installed on the monolithic belt.

The invention is illustrated by drawings. Figure 1 shows a General view of the platform precast-monolithic joint in isometry, figure 2 is a transverse section "1-1" of the joint, figure 3 is a longitudinal section of the joint "2-2", figure 4 is a section of the joint "3-3".

The prefabricated monolithic joint joint includes an internal load-bearing wall panel with openings blocked by a crossbar 1 and framing their posts 2, multi-hollow reinforced concrete slabs 3 supported on a crossbar, with 30 mm thick concrete diaphragms 4 installed in the voids, rebar releases 5 of the reinforcement cage 6 of the crossbar panels, concrete-filled reinforced monolithic belt 7, "P" -shaped reinforcing bars-outlets 8, connecting the reinforcement 9 of the monolithic belt with vertical working rods 10 of the rack of the overlying panel , embedded parts 12 with centering pyramids 13, which are included in embedded parts 14 with centering pyramidal openings, indirect reinforcement reinforcement 15 of the support section of the wall panel strut.

The device operates as follows. In the holes located at the end of the multi-hollow floor slab 3, at a distance greater than the thickness of the internal load-bearing wall panel, concrete diaphragms 4 are installed with a thickness of at least 30 mm. The panel crossbar is reinforced with a reinforcing cage 6, from which the reinforcing outlets 5 protrude beyond the plane of the upper edge of the crossbar, and floor slabs 3 are supported on this plane. Then, the working reinforcement 9 of the monolithic belt 7 is installed and this reinforcement is connected to the reinforcing outlets 5 coming out of the outlet of the underlying panel . Above, above the working armature 9, embedded parts 12 are arranged with anchors down with the centering pyramids 13 protruding upwards. “P” -shaped reinforcing bars-outlets 8 are tied to the working reinforcement 9, the vertical ends of which are passed into the holes arranged in the shelf of the plate and connected to the vertical working rods 10 of the overlying panel strut. The support zones of the panel racks, in which the embedded parts 14 with centering pyramidal holes are placed, are reinforced with indirect reinforcement 15. The space between the upper plane of the upper flange of the underlying panel and the ends of the floor slabs together with the diaphragm is filled with concrete to the level of the upper plane of the floor panels and the upper plane of the embedded part 12. After the hardening of concrete on the protruding centering pyramids 13, as on the guides, the racks of the overlying panel are mounted by means of embedded parts 14 cent pyramidal hole.

The presence of these new features in a single combination provides a clear alignment of wall panels during installation, a rigid connection of wall panels with openings by means of embedded parts with a centering pyramidal hole, the necessary bearing capacity of the platform joint in panels with large openings
