Abstract

Usage: flooring in reconstructed buildings. SUMMARY OF THE INVENTION: Intermittent punches pierce walls. The plates are laid starting from the extreme, plant them alternately at one end in shrab. The other end of the plate rests on a temporary support. The middle sections of the seams between the plates are monolithic, equal to 0.7 - 0.8 of the span. After the concrete reaches a strength of at least 25%, the temporary supports are removed. Then, the end sections of the seams and the seams between the end faces of the plates and the walls are monolithic. 1 ill.

Description

The invention relates to construction and can be used in the installation of floors in reconstructed buildings,

The purpose of the invention is to increase the bearing capacity due to the redistribution of forces from shear forces in the joints between the plates.

The drawing shows a fragment of the overlap.

The floor slabs 1 are laid alternately at one end in the bays 2 of the opposite walls 3, the other are supported on temporary supports 4. The extreme slabs are recessed with their longitudinal sides into the grooves 5 made in the end walls 6 of the building at the level of the ceiling,

The method is carried out as follows.

Intermittent punches 2 are punched in the walls 3, the length of which corresponds to the width of the floor panel. In the end walls 6, grooves 5 are made with a depth of 30-35 cm. Then, slabs 1 are made into stitches 2 in a checkerboard pattern and laid on a layer of mortar. The free ends of the plates are supported by temporary supports 4. The longitudinal sides of the extreme plates are recessed into the furrows 5 of the end walls 6 of the building. After laying the plates 1, the middle sections of the seams between the plates 1 are monolithic, equal to 0.7 - 0.8 of the span. Structural fine-grained concrete is used to grout the joints. Withstand until concrete reaches a strength of at least 25%. Then the temporary supports 4 are removed and the end sections of the joints between the plates 1 and the joints between the ends of the free ends of the plates and the supporting walls 3 are monolithic.

Two-stage monolithic keyway seams provide greater equal-hour
