Half-rib laminated floor slab with floor heating pipe groove

Abstract

The invention discloses a half-rib laminated floor slab with a floor heating pipe groove. The laminated floor slab is provided with an open floor heating pipe groove, on the premise that the thicknessof the original laminated floor slab structure layer is not increased, the reinforced concrete structure layer is poured after the floor heating pipe groove is recessed into the laminated floor slab,an upper opening of the floor heating pipe groove is flush with the surface of the laminated floor slab after pouring of the reinforced concrete structure layer, and the floor heating pipe groove is50 mm deep and 80 mm wide. The laminated floor slab adopts the configuration of floor heating pipe straight grooves and the unidirectional stress reinforced concrete floor slab, and the floor heatingpipe straight grooves are arranged along the floor slabs at intervals; floor heating foldback grooves are arranged at positions where the positive and negative bending moment values of the laminated floor slab are low, and in the positive bending moment position of the laminated floor slab, the floor heating pipe straight grooves are arranged at intervals; and the compressive stress zone of the cross section of the laminated floor slab is divided into relatively independent plate ribs, the plate ribs are cut into half ribs by the floor heating foldback grooves, and reinforcing bars are arranged at the stress loss position of the laminated floor slab formed by the floor heating pipe groove recessed into the laminated floor structural layer. The half-rib laminated floor slab has the advantage that in the existing floor slab construction process, fine stone concrete installation of floor heating pipe is omitted.

Description

technical field [0001] The invention relates to a half-rib laminated floor slab with floor heating pipe grooves, belonging to the technical field of prefabricated buildings. Background technique [0002] The country vigorously promotes the technological innovation of prefabricated buildings, the purpose of which is to enhance the degree of industrialization of buildings, overcome my country's resources, energy bottlenecks and environmental pressures, and make economic operations enter a state of sustainable development. Using the current laminated floor slabs for the construction of residential buildings, the prefabricated concrete layer and the overall post-cast concrete layer are combined, the overall firmness, good seismic performance, and higher efficiency than the traditional process of the formwork cast concrete floor slab, the laminated floor slab and the heat dissipation are even, and the living is comfortable The combination of ground heating technology has become a...
