Abstract

FIELD: building industry. SUBSTANCE: floor has header joists fixed by their ends into building walls and lower panel flanges supported by header joists. Panel cross section in plane perpendicular to header joist axes is in the form of several stacked rectangles. Lower rectangle height is equal to height of lower header joist flange, difference between rectangle lengths is equal to two widths of lower header joist flange. Panels are formed of gypsum concrete mixture with wood reinforcement arranged into gypsum concrete. Wood reinforcement is oriented parallel to long side of upper rectangle and has T-shaped cross area. Length of upper reinforcement part is equal to upper rectangle length. EFFECT: simplified structure, reduced cost. 2 dwg

Description

The invention relates to the construction and can be used in the construction of single-story houses.

It is known overlapping (see AS USSR No. 1631144 from 04.24.1989, MKI 6 E 04 B 5/12), including I-beams fixed with ends in the walls, wooden overlapping panels supported on their lower shelves and flexible prestressed threads, supported on the upper flanges of the I-beams and brought out through the outlet openings in the floor panels under their lower face, and the floor is equipped with profile elements that are movably fixed on the lower face of the floor panels within the parts of the flexible threads brought to this face with the formation of threads along the length parts of variable stiffness, while the ends of the profile elements are made with bends, recessed into the outlet for supporting flexible threads.

A disadvantage of the known overlap is its high cost.

Known wooden flooring, taken as a prototype (see AS USSR No. 1631145 from 04.24.89, MKI 6 E 04 B 5/12), including I-beams supported on the walls of the building, wooden span elements resting on the lower shelves of the beams , reinforcing elements in the form of prestressed flexible threads interacting with the upper shelves of the beams and brought out through the outlet openings in the span elements under their lower face, and the part of the thread brought out under the lower face of the span elements is bent and supported on these faces in the inflection nodes at the outlets of the extreme fixing parts and intermediate fixing parts, staggered relative to the extreme ones, and the parts of adjacent threads brought out under the lower face are opposite and placed with overlap in the knots of the inflection with the formation of a prestressed spatial system within each project.

The disadvantages of the known wood flooring are its high complexity and cost.

The aim of the invention is to eliminate this drawback, namely, simplifying the design and reducing the cost of overlap.

This goal is achieved by the fact that in the ceiling, including the supporting beams fixed by the ends in the walls and the panels supported on their lower shelves, which in the section perpendicular to the longitudinal axes of the supporting beams have the form of two rectangles laid on top of each other, the height of the lower rectangle being equal to the height the lower shelf of the beam, and the difference in the lengths of the rectangles is twice the width of the lower shelf of the beam, and the panels themselves are made of gypsum concrete, in which there is a wooden reinforcement oriented parallel to the long st the upper rectangle of the section of the panel and having a T-shape in cross section, the length of the upper part of the reinforcement being equal to the length of the upper rectangle and the length of the lower part to the bottom rectangle.

The invention is illustrated by graphic materials, where in Fig.1 shows the overlap in the context of Fig.2 is a section aa.

The overlap contains load-bearing beams 1, which can be T-shaped or I-shaped and supported on their lower shelves of panel 2, made of gypsum concrete mixture. In a section perpendicular to the longitudinal axes of the supporting beams 1, the panel 2 has the form of two rectangles laid on top of each other, the height of the lower rectangle being equal to the height of the lower shelf of the beam 1, and the difference in lengths of the rectangles of the section of the plate 2 is equal to twice the width of the lower shelf of the beam 1. In addition , in the upper part of the panel 2 there is a wooden reinforcement 3 oriented parallel to the long side of the upper rectangle of the section of the panel 2. The reinforcement 3 has a T-shape in cross section, the length of its upper part being equal to the length of the upper yamougolnika and the length of its lower part - of the rectangle. The reinforcement 3 can be made of a whole piece of wood, or of two pieces, fastened, for example, with nails. After installation, the lower part of the ceiling is putty and painted (not shown in Figs. 1, 2).

The ceiling is mounted as follows. First, the supporting beams 1 are fixed in the walls, then plates 2, made separately, are laid on their lower shelves, after which the lower surface of the ceiling is putty and painted.

The application of the proposed overlap will significantly simplify and reduce the cost of building one-story houses.
