Heat preservation and fire prevention integrated template and preparation and installation method thereof

Abstract

The invention belongs to a heat preservation and fire prevention integrated template and a preparation and installation method thereof. The heat preservation and fire prevention integrated template comprises the following materials in part by weight: 215 to 220 parts of cement, 100 to 105 parts of coal ash, 13 to 15 parts of particle lightweight heat preservation material, 1 to 1.2 parts of polyvinyl alcohol, 0.3 to 0.4 part of cellulose ether, 0.4 to 0.5 part of redispersible glue powder, 0.5 to 0.6 part of early strength agent and a proper amount of water. The heat preservation and fire prevention integrated template can be arranged on a single face or double faces of a concrete cast-in-situ wall body according to design requirements. The heat preservation and fire prevention integrated template has heat preservation and fire prevention properties, serves as a building template which is not disassembled and is used together with the building with the same service life, and has the advantages of saving the materials, changing waste into treasure, reducing pollution and saving energy, along with light weight, fire prevention, high surface strength, good heat preservation effect and low cost. The invention also provides the preparation and installation method of the heat preservation and fire prevention integrated template. The method is practicable, simple and convenient; the cost is low; and construction steps are saved.

Description

technical field [0001] The invention belongs to an integrated formwork for heat preservation and fire prevention and its preparation and installation method. Background technique [0002] At present, the method of adding an insulation layer on the outer side of the outer wall of the floor of the cast-in-place reinforced concrete is to lay a polystyrene foam board with a thickness of about 5 to 10 cm on the outer side of the outer wall of the outer wall of the reinforced concrete, and place it on the wall. Drill holes on the outer side of the body, and then use T-shaped anchors to fix the polystyrene foam board and the outer side of the wall as a whole. 2-5mm cement material layer. This method of adding the insulation layer cannot make the insulation layer and the outer wall tightly and firmly connected, because the T-shaped anchor is connected to the outer wall by means of the bolts in it extruding the plastic expansion tube of the outer layer. , With the aging of the plas...

AI Technical Summary

Problems solved by technology

[0003] There are also construction companies at home and abroad who have pre-embedded the connector fixing rods connected with the polystyrene foam plastic board on the outer side of the outer wall of the reinforced concrete floor when pouring the outer wall of the floor, and the floor to be poured Installing polystyrene foam plastic board after the outer wall is dry and solid, actually only saves the process of drilling holes on the outer side of the wall. Impact on the construction of the wall

As we all know, during the construction of the outer wall of the floor of the cast-in-place reinforced concrete, two steel formworks are clamped on the position of the cast-in-place reinforced concrete wall, and then the reinforced concrete slurry is poured in the steel formwork after it solidifies. Then remove the steel formwork to form a floor exterior wall made of cast-in-place reinforced concrete. Therefore, the fixing rods of the connectors protruding from the surface of the exterior wall have seriously affected the construction of the exterior wall of the floor, resulting in complicated construction and slow construction. Poor thermal insulation effect and high energy consumption
