Description

The utility model relates to the construction of buildings, in particular to the installation of interfloor overlappings and coatings of the architectural and construction system SDS-2010 and can be used in the construction of large-panel buildings.

Known series of large-panel reinforced concrete buildings, for example, the Leningrad series 137 or 97 series.

The solutions of the existing serial systems are limited by a rigid set of overall block sections, primarily due to the structural solutions of the load-bearing structures and the possibilities of the house-building plants for the production of concrete products.

The technical problem solved by the proposed utility model is the need to maximize the current trends of free space planning, as well as the flexibility of recruiting and ratio of apartments, that is, the free choice of the number of rooms and area in residential large-panel buildings.

The task is solved by the absence of supporting wall structures on an area of up to 38 ÷ 40 square meters. m

The closest analogue of the patented solution is the interfloor overlap, known from the RF patent №62622, published on 27.04.2007. The joints of the vertical parts of the frame structure are located in the middle of the heights of the interfloor space. The slab is made reinforced with the release of working reinforcement along the transverse ends of the upper belt of the slab. The presence of valve outlets along the transverse ends of the upper belt of the floor slabs allows the plates to be interconnected by welding with monolithing of the joints, which ensures their work according to a continuous scheme.

A disadvantage of the known solution is the rigid limitation of the aspect ratio of the floor slabs and, accordingly, the limited range of premises.

The technical result of the patented solution is a cell of about 6.6 m by 6 m without bearing walls inside the cell, which allows for free planning of the total area of the structural cell formed by the proposed floor structure and external bearing walls with simultaneous control of the deflection and an increase in the length of the room at a constant thickness overlap.

The claimed technical result is achieved due to the construction of interfloor overlapping, including two rectangular plates, each of which contains prestressing reinforcement, is made on the ends with bevel edges and stamps with the formation of dowels and can be supported on the three ends on the bearing walls, and on the fourth large end connected to the second plate, while the nodes connecting the plates on the larger side of the plate represent the connection of protruding keys, but not extending beyond the edge of the plate, parts Atura assembly elements by welding, and the seams and wells of the nodes filled with concrete solution.

The mounting elements are steel plates, angles and rods.

In the particular case of the implementation of the useful model, fittings parts protruding from the keys are loops.

In the particular case of the implementation of the useful model, the parts of the reinforcement projecting from the keys are plates.

Thus, slabs with prestressed reinforcement, made with the possibility of support on three sides, are used to overlap the spans (about 6 ÷ 7 m long), which allows you to control the deflection and increase the length of the room at a constant overlap thickness. Due to the support of each plate on one of the large sides of the supporting wall, the magnitude of the bending moment is reduced. The joint is made with bevel edges and has stampings for the best joint work of two adjacent floor slabs in one hard disk (so that both plates work in the sagging area together).

Formed cell volume with the proposed interfloor overlap can be: 5.4 ÷ 6.4 m X 6.6 ÷ 7.2 m

Further, the solution is explained by reference to the figures, which show the following.

FIG. 1 - general view of the floor slab.

FIG. 2 - side edge of the slab.

FIG. 3 - node connecting plates with loops.

FIG. 4 - node connecting plates with plates.

The proposed interfloor overlap 1 (can also be used for coating) is a system of a number of plates with prestressing reinforcement and without it. For example, two plates 2 with dimensions of about 2.5 ÷ 3 m to 6 ÷ 7 m. Each plate contains prestressed reinforcement and is made on the ends with bevel edges (4 and 5) and stamps with formation of keys 6. Each of the plates 2 is supported by three ends of the bearing walls, and the fourth large end (length 6 ÷ 7 m) is connected to the second plate. The nodes 7 and 8 of the plates 2 on the larger side of the plate represent the connection of embedded parts by the mounting elements 11 by means of welding. The mounting elements 11 are steel plates, angles and rods. Embedded parts are loops 9 or embedded plates 10 protruding from keys 6, but not extending beyond the edge 4 of the plate. The seams and wells of the nodes after the installation of the plates are filled with concrete.

In turn, the slab without prestressing is supported on four sides and tied into a common hard disk with the rest of the plates through the system of embedded parts and mounting elements, followed by monolithing the seams.

The flexibility of the set and the ratio of apartments, as well as the possibility of free planning in the architectural and construction system SDS-2010 are implemented through the use of separate structural cells with dimensions of up to 6.6 by 6.0 meters, which, according to the laws of architectural planning standards (meridional type, latitudinal and the angular type of the block section) are “strung” onto the stair-elevator unit (several types ranked by the number of floors of the building, lift-free, with 1 or 2 elevators on me). The possibilities of the Europeanized “pallet” production of reinforced concrete and full-bodied floors of the ACC-2010 structural cell allow changing the types of floors depending on the size of the premises and the customer’s needs (the floors form an architectural-constructive cell along with supporting external and internal walls).

In particular, slabs with prestressing reinforcement supported on three sides were used to overlap the spans, 6.6 meters long, which allows you to control the deflection and increase the length of the room with a constant overlap thickness, and to block individual rooms Slabs without prestressing with a different nature of work (perception and distribution of efforts).

Such combinations of elements of architectural and structural; cells allow you to reduce the technical and economic indicators of the structure (such as metal consumption and the volume of concrete per unit total area), which ensures the profitability of this production relative to the previously used large-panel counterparts.
