Fire-proof physical connection type composite disassembling-free thermal insulation formwork and production and manufacture technology thereof

Abstract

The invention relates to a fire-proof physical connection type composite disassembling-free thermal insulation formwork and a production and manufacture technology thereof. The fire-proof physical connection type composite disassembling-free thermal insulation formwork is formed in a way that the middle of the fire-proof physical connection type composite disassembling-free thermal insulation formwork is provided with a thermal insulation core material, two side surfaces of the thermal insulation core material are each provided with an open slot; 3-5 mm anti-crack mortar is attached to one surface of the thermal insulation core material; glass fiber screen cloth is pressed into the middle of the anti-crack mortar, an operation of filling up and making even is carried out to form a stress protection layer, during practical construction assembling, the side surface to which the anti-crack mortar is attached and concrete are poured together; and the other side of the thermal insulation core material is provided with two layers from inside to outside, wherein an inner layer, namely a first layer is provided with light fire-proof thermal-insulation mortar, the anti-crack mortar is attached to the outer side of the light fire-proof thermal-insulation mortar to be pressed into alkali-proof glass fiber screen cloth so as to form water prevention, a protection layer is formed, then, theoperation of filling up and making even is carried out, and therefore, a fire-proof thermal insulation layer formed by a fire-proof construction layer and the protection layer and the thermal insulation core material are in physical connection through the open slots and mutually permeate. In a similar way, the stress protection layer on the inner side surface and the thermal insulation core material are in the physical connection through the open slots.

Description

technical field [0001] The invention belongs to the technical field of building energy saving, and in particular relates to a fireproof physically connected composite non-dismantling thermal insulation formwork and a production process thereof. Background technique [0002] At present, the demolition-free thermal insulation formwork has gradually been popularized and applied in the market, and it is an important part of the integration of building thermal insulation structures. According to the practice in recent years, the current demolition-free thermal insulation formwork mainly has the following deficiencies: [0003] 1) Most of them fail to meet the requirements of current standards in terms of fire performance, and there are potential fire safety hazards. The main reason is that the fire prevention ability of its outer protection is not enough, and there is a big potential safety hazard. [0004] 2) (Insulation) The thickness of the outer side of the core material is ...

AI Technical Summary

Problems solved by technology

[0003] 1) Most of them fail to meet the requirements of current standards in terms of fire resistance, and there are potential fire safety hazards

The main reason is that the fire prevention ability of its outer protection is not enough, and there is a big potential safety hazard

[0004] 2) (Insulation) The thickness of the outside of the core material is relatively thin, the strength is low, and there are quality and safety hazards such as mold expansion and slurry leakage

However, if the outer side of the (insulation) core material is thicker in order to improve the strength, the quality of the non-dismantling insulation formwork will directly increase, and it cannot be stably arranged on the outer wall

[0005] 3) The composition of the board is mostly composed of organic and inorganic materials, and it is difficult for materials with different properties to form a safe and reliable connection. Traditional interface agents (mainly emulsion-type interface agents, composed of chemical polymer materials as the main component, Supplemented with other fillers, the emulsion-type interface agent is divided into one-component and two-component according to its composition and applicable base. Durable, but also bring environmental pollution during production
