Concrete building combined with heat insulating framework and its construction method

Abstract

This invention is built-up plate heat preservation and insulation concrete building and its construction method. The heat preservation and insulation layer is also used as wall framework, concrete wall body base course is placed in wall framework, wall framework is consisted by two pieces of parallel set polystyrene foam plastic side plate, inner fixed billet is set in the plate, steel bar junction piece and welded mesh is set between the billet. PVC baffles are pasted on four walls of door and window mouth depth part, glass fiber grid layer is pasted on PVC baffles, inner and outer surface of wall heat protection plate is enclosed by glass fiber grid layer. Expanded metal is fixed on the layer, and it enclosures the outer surface of the heat protection plate, cement mortar is filled in mesh of the expanded metal, the thickness of the mortar is same to the expanded metal, concrete drowned orifice is opened on down table that at door and window mouth. The bottom layer of polystyrene heat protecting floor slab is floor slab plate that made of flute type polystyrene foam plastic pre-buried steel, rib joist steel is set in the flute, and it is placed with top layer as one body.

Description

(1) Technical field [0001] The invention relates to a concrete building and a construction method, in particular to a thermal insulation concrete building and a construction method. (2) Background technology [0002] Existing thermal insulation concrete buildings and construction methods use polystyrene foam (EPS) as wall formwork and floor slab formwork, and pour concrete in the center. Although it has many advantages such as good thermal insulation and sound insulation effects, and convenient construction, there are still the following points to be improved: for example, the strength of polystyrene thermal insulation wall formwork is low, and it is easy to expand and crack; the corners of doors and windows are easily damaged, and the exterior The wall lacks fixed points, which is not convenient for wall decoration; after the wall concrete is poured, the wall decoration work cannot be done immediately, which prolongs the overall construction time; the polystyrene insulation...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a thermal insulation concrete building with combined formwork and its construction method, which solves the technical problems of industrialized construction of energy-saving buildings; also solves the problems of low surface strength of wall formwork and easy damage to corners; also solves the problem of preventing Problems of Crack Resistance and Earthquake Resistance of Thermal Insulation Concrete Buildings
