Reinforced composite thermal insulation template

Abstract

The invention relates to the technical field of the wall body thermal insulation used for buildings, in particular to a reinforced composite thermal insulation template. The invention aims to provide the reinforced composite thermal insulation template, which has the advantages of low manufacture cost and good thermotechnical performance, and the phenomenon that an outer side cement base and other adhesive layers are fallen after a thermal insulation template body is molten by the high temperature of big fire is avoided. The purpose of the reinforced composite thermal insulation template is realized by the following technical scheme that the reinforced composite thermal insulation template comprises a thermal insulation template body, wherein the inner side of the thermal insulation template body is provided with a reinforcement layer, and the outer side of the thermal insulation template body is provided with an outer side reinforcement layer. The reinforced composite thermal insulation template is characterized in that the inner side reinforcement layer is connected with the outer side reinforcement layer by a connection piece made of noncombustible or fire-retardant materials. The reinforced composite thermal insulation template has the beneficial effects that a rock wool or foam thermal insulation template is molten by the high temperature of the big fire when the composite thermal insulation template is burnt in the big fire, the outer side cement base and other adhesive layers can not collapse or fall because the outer side cement base, an inner side cement base and a cast-in-place concrete wall body are connected by the connection piece made of noncombustible or fire-retardant materials, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the technical field of building wall insulation, in particular to a reinforced composite insulation formwork. Background technique [0002] At present, the energy-saving building and wall insulation technology generally adopts the method of pasting polystyrene boards on the outer walls of buildings for insulation, and also adopts the practice of placing polystyrene boards or steel wire grid polystyrene boards on the inside of the outer formwork for cast-in-place concrete, referred to as large The cast-in-place concrete insulation wall is built into the mold. While organic panels such as polystyrene foam board (EPS) and extruded polystyrene board (XPS) are widely used, fire accidents also occur frequently. There are many reasons for the fire, but the flammability of insulation materials such as polystyrene boards is an important reason. [0003] For example, in the prior art, there is a FS external formwork cast-in-place concr...

AI Technical Summary

Problems solved by technology

If this kind of thermal insulation template is burned in a fire, the rock wool insulation board or foam insulation board will be melted by the high temperature of the fire. Because there is no effective connection between the outer cement base and the inner cement base and the cast-in-place concrete wall, the outer cement base and other attachment layers It will inevitably collapse and fall, which does not meet the requirements of the state
