Abstract

The invention relates to the construction and can be used as interfloor overlaps of buildings and structures. The purpose of the invention is to increase the carrying capacity. The overlap and the covering of buildings and structures contain the supporting elements 1 and the plates 2 installed on them. The interacting side faces of the supporting elements and plates are made at an angle to the vertical and are provided with slip plates 5. When plates 2 are loaded, there is an increase in expansion reactions, which compress their stretched zone formed by the applied load, turning the stretched zone into a compressed zone due to the wedging effect. The angle of inclination of the side edge of the load-bearing elements depends on the mass of the plate, the height of its side edge, the linear intensity of the uniform load distribution of the own weight of the plate and the calculated span of the plate, and the angle of the side edge of the plate is determined depending on the angle of inclination of the side edges of the bearing elements plate and the height of the supporting side face of the plate. 6 Il.

The invention relates to the construction of n can be used as interfloor overlaps of buildings and structures.

The aim of the invention is to increase the carrying capacity of the overlap.

Figure 1 shows the overlap plan; Fig. 2 shows a section A-A in Fig. 1 with an overlapping plate a being in the initial position; on fig.Z - section overlap with the load from the plates, support reactions and resultant; Fig. 4 is a section B-B in Fig. 1 with overlapping plates at the moment of their installation on non-cyanjie elements; Figure 5 - the same, with overlapping plates, laid M1 on the supporting elements, and a BaHHjiiM shaped arch effect; Fig 6 - the same, with the overlapping plates that have taken the vertical load

The overlap and the covering of buildings and structures include load-bearing elements 1, on which the plates 2 are laid.

The lateral faces 3 of the slab 2 overlap and the lateral faces 4 interacting with them of the supporting elements 1 are provided with slip plates 5 The lateral edges of the 4 supporting elements are inclined to the vertical by an angle, the magnitude of which lies within

The installation of the ceiling and the covering of buildings and structures is carried out in the following sequence.

On the supporting elements 1 are installed 2 floor slabs. Overhanging the lower plane by the amount of h, the oblique end face 3 of the slab 2 overlaps, interacting through the slip plates 5, transfers the load of the slab to the lateral inclined face 4 of the supporting element 1 and, perceiving horizontal forces, forecloses the slab 2 and ensures its deflection upwards uh value

Claims (1)

When loading the slab, there is an increase in the spacer reactions, which compress the stretched zone of the slab formed by the applied load, turning the stretched zone into a squeezed zone due to the wedging effect, which makes it possible to fully use the strength characteristics of the material, such as concrete, to save reinforcement, installed for the perception of tensile forces, as well as to simplify the reinforcement of floor slabs.
