A fire-proof decoration integrated fire-proof isolation belt

Abstract

The present invention provides a new type of integrated fire protection isolation belt for fire protection decoration, which is laid on the building exterior wall (1), corresponding to the height area of ​​the floor slab between floors, and is in the shape of a belt surrounding the wall, extending from the building exterior wall (1) to the The outer layer includes a bonded mortar layer (2) and a fireproof insulation board layer (3) in sequence, and fireproof insulation boards are closely arranged in the fireproof insulation board layer (3), and the fireproof insulation board includes a heat preservation board (31), a cover layer (32) And L-shaped fixture (33), cover layer (32) is a metal plate, and insulation board (31) is the fireproof insulation board that glass fiber and water-soluble phenolic resin prepare. The fireproof isolation board layer in the fireproof isolation belt of the present invention can be prefabricated, which reduces the difficulty of on-site construction. The adhesive mortar layer covers the outer wall in an all-round way, the structure design of the fireproof isolation board and the new insulation board improve the fireproof performance. Compared with the existing The fireproof isolation system of the present invention has the advantages of simple structure, convenient construction, good fireproof and thermal insulation performance, and is beneficial to popularization in the construction field.

Description

technical field [0001] The invention belongs to the technical field of fireproofing and heat preservation of building exterior walls, and in particular relates to a novel integrated fireproof isolation belt for fireproof decoration. Background technique [0002] With the development of the city, the urban population is becoming denser and the number of building floors is getting higher and higher. Once a fire breaks out in a building, the fire will spread rapidly along the outer wall to the whole building. The country has agreed on the fire rating of building exterior wall materials, but at present there are still various quality problems in various exterior wall materials, resulting in endless fires spreading and seriously endangering people's lives and property safety. [0003] The fire isolation belt is set in the middle of various widely used organic insulation materials on the outer wall, which plays the role of isolating the continuity of the upper and lower organic in...

AI Technical Summary

Problems solved by technology

[0005] 1. Rock wool cannot be directly bonded to the wall when it is used as a fire isolation belt, which requires complex construction techniques, which increases the construction period and construction difficulty;

[0006] 2. The structural strength of rock wool is weak, and the tensile strength of the vertical surface just meets the national requirement ≥ 15KPa. The fire isolation belt made of rock wool will fall off due to its low strength;

[0007] 3. The fireproof isolation belt has both thermal insulation performance, but the thermal insulation performance of rock wool is poor, and the thermal conductivity is generally about 0.05W / (m·K);

[0008] 4. Although the fire protection grade of rock wool has reached the requirements of Class A, the overall fire performance of the fire isolation zone formed by rock wool needs to be improved;

[0009] 5. Enterprises that produce rock wool are high-pollution and high-energy-consuming industries, which is not conducive to responding to the energy conservation and emission reduction advocated by the state
