Description

The invention relates to construction, in particular to elements of building structures - prefabricated panels of heated buildings, for example, for insulated floors.

Known panel designs with channels located along the direction of the span and filled with insulation. The disadvantage of such structures is the complexity of the uniform laying of the insulation along the entire length of the channels and the impossibility of using bulk heat-insulating materials as insulation as the channels are open at the ends of the panel.

Known building panel with coaxially located from the side of the side. surfaces with blind channels, symmetrical about the longitudinal axis of the panel, perpendicular to the direction of the span, and the load-bearing core (in the middle of the panel section) can be made of heat-insulating concrete. The disadvantage of the known design is the increased consumption of concrete due to the fact that each pair of opposite voids has a total depth not exceeding half the width of the panel. Filling such voids with heat-insulating material is not feasible due to their small size and the fact that the voids are located on opposite side surfaces - this requires additional re-edging of the panel.

The closest in technical essence to the claimed design is the prefabricated panel selected as a prototype with voids formed by rigid hollow liners measuring the width of the panel. The liners are made with end caps with holes and are filled with loose heat-insulating material.

The disadvantage of the known technical solution is the inclusion in the panel structure of rigid hollow non-removable liners for the formation of channels, which increases the consumption of materials and complicates the process of manufacturing the panel.

The aim of the invention is to reduce the consumption of materials and improve the manufacturability of the panel.

This goal is achieved by the fact that the channels (voids) of the known prefabricated panel are made with closed ends, forming ribs along the longitudinal edges, when

When the structure operates on the operational load, the upper plate 1 of the panel works mainly in compression, the lower plate of the panel 2 in tension, and the longitudinal ribs of the panels 4 and 5 perceive the lateral forces arising from bending. The transverse ribs additionally increase the rigidity of the structure, which is necessary, for example, when the panel is subjected to bending and torsion. ?

The dimensions of the panel are determined based on the following: the length of the panel is determined by the length of the span to be covered and the conditions of support: the thickness of the panel is determined from 15 conditions of the required thermal protection of the floor; the thickness of the bottom plate 2 and the transverse ribs 3 is determined from the conditions for the safety of the longitudinal reinforcement 9 and on. pepper flat frames 10 against corrosion; 20 thickness of the upper slab 1. dimensions and between which the thermal insulation of longitudinal compressed 8 and longitudinal material is located 6. Slabs transverse to the stretched 9 reinforcement bars of the deflector and longitudinal rib 4 are made based on the calculation of the cross section (cast and cast and are a single concrete , as in the calculation of the I-section with a ny body Longitudinal rib 5 is made 25 by the boundary of the compressed zone, passing in the upper after filling the channels of the heat-insulating shelf) to the maximum bending material by molding the plug; thickness of the longitudinal ribs of the cuffs 7. The panel is reinforced longitudinal. divided by the cross-section calculation into. action of transverse forces for each section of the panel length bounded by transverse ribs.

Longitudinal ribs of variable thickness reduce concrete consumption per panel. The design of the panel excludes the use of non-removable liners, which also reduces the material consumption and simplifies the process of manufacturing the panel. Filling. The voids are filled with a fully open cross section of each channel, which simplifies the process of filling the voids, i.e. also improves the manufacturability of Panel Fabrication. /
