A self-insulating laminated floor slab and its construction method

Abstract

The invention discloses a self-insulation laminated floor slab and a construction method thereof, comprising a prefabricated bottom slab, a sandwich insulation layer and a cast-in-situ concrete layer are sequentially arranged above the prefabricated bottom slab; Shear bond with low thermal conductivity. The construction method includes the following specific steps: 1) Binding the prefabricated steel frame and steel truss, installing shear keys on the prefabricated steel frame, pouring concrete, and obtaining a prefabricated floor after curing; 2) laying a sandwich insulation layer above the prefabricated floor, The steel truss is located in the sandwich insulation layer, and the upper end of the shear key is exposed to the sandwich insulation layer; 3) The precast concrete after laying the sandwich insulation layer is transported to the site for hoisting; 4) The cast-in-place steel skeleton is bound on the upper end of the shear key, and the concrete is poured , to obtain the cast-in-situ concrete layer; 5) plastering the bottom of the slab and construction of the surface layer on the slab surface. The invention can not only ensure that the insulation layer is not easy to be damaged, improve user experience, but also improve the insulation effect.

Description

technical field [0001] The invention relates to a heat-insulating laminated floor, in particular to a self-insulating laminated floor and a construction method thereof. Background technique [0002] With the implementation of the "green building" development strategy, the country's requirements for building energy conservation are getting higher and higher. In the past, only the outer walls and roofs needed insulation, but now the household floors also need insulation; therefore, the household floors of each floor are required to be insulated. An insulation layer needs to be provided, and according to the different positions of the insulation layer, the existing construction methods include the following two methods: 1) the insulation layer is above the structural layer; 2) the thermal insulation layer is below the structural layer. However, when the insulation layer is above the structural layer, because the insulation layer is generally made of relatively loose and soft ma...

AI Technical Summary

Problems solved by technology

However, when the insulation layer is above the structural layer, because the insulation layer is generally made of relatively loose and soft materials, after the surface layer is made on it, the surface layer is prone to uneven force, resulting in cracks, and the user experience is not good. And when the building is refurbished, the insulation layer is easily damaged by the user, which affects the energy-saving effect of the building; when the insulation layer is below the structural layer, in addition to being easily damaged and affecting the energy-saving effect, the adhesion to the plastering layer is limited. The plaster layer is easy to fall off

Therefore, the existing technology has the problems that the insulation layer is easily damaged and the insulation effect is not ideal.
