External-framework built-in composite insulation board and cast-in-situ concrete integrated wall structure and manufacturing method thereof

Abstract

The invention relates to an external-framework built-in composite insulation board and cast-in-situ concrete integrated wall structure and a manufacturing method thereof with an aim to provide the wall structure and the manufacturing method which are capable of realizing insulation and structure integration of a building wall, reducing comprehensive cost and facilitating leveling of the outer surface. The technical scheme includes that the wall structure comprises a cast-in-situ concrete base wall body, a composite insulation board and a plaster layer, the composite insulation board comprises an insulation board substrate, the inner side of the insulation board substrate is an interface layer while the outer side of the same is a reinforcing layer, connecting pieces penetrating the reinforcing layer, the insulation board substrate and the interface layer are arranged on the insulation board, and the composite insulation board and the cast-in-situ concrete base wall body are firmly connected together through the connecting pieces; the thick plaster layer is arranged on the outer side of the composite insulation board. The external-framework built-in composite insulation board and the cast-in-situ concrete integrated wall structure and the manufacturing method thereof have the advantages that cost is low, cost of the manufactured wall body can be reduced, and insulation and the structure of the building wall can be integrated.

Description

technical field [0001] The invention relates to the technical field of wall heat preservation, in particular to a cast-in-place concrete integrated wall structure with a built-in composite heat preservation board in an external mold and a manufacturing method thereof. Background technique [0002] At present, the energy-saving building and wall insulation technology generally adopts the method of pasting polystyrene boards and other thin plasters on the outer walls of buildings for insulation, and also adopts the method of placing polystyrene boards or steel wire grid polystyrene boards on the inside of the outer formwork for cast-in-place concrete. The method is referred to as large mold built-in cast-in-situ concrete insulation wall. For example, the JGJ 144-2004 industry standard issued by the Ministry of Construction discloses an external thermal insulation system for cast-in-place concrete external walls with built-in polystyrene boards in the external mold. The inner ...

AI Technical Summary

Problems solved by technology

Its defect is: because of the limited force of the polystyrene board, the mortar reinforcement layer with glass fiber mesh is located outside the anchor bolt, and the outer surface of the polystyrene board can only be plastered thinly (less than 1 cm) and cannot be plastered thickly ( greater than 1 cm), the inability to carry out thick plastering means that the outer layer cannot be effectively leveled, and there are certain fire hazards
