Fire barrier belt with steel mesh frame rock wool board and construction method for fire barrier belt

Abstract

The invention belongs to the field of outer-wall external thermal insulation for buildings, and particularly relates to a fire barrier belt with a steel mesh frame rock wool board and a construction method for the fire barrier belt. The fire barrier belt comprises a cement mortar leveling layer, a steel mesh frame rock wool board thermal insulation layer, an adhesive powder poly-phenyl granule thermal insulation slurry leveling layer, an anti-crack mortar plastering layer, an elastic bottom coating bonding layer, and a facing layer which are sequentially arranged from inside to outside. The fire barrier belt has the advantages that the method for fixing a rock wool fireproof board in the rock wool fire barrier belt is re-designed, and the steel mesh frame rock wool board can be fixedly connected with various walls, including solid brick walls, concrete small hollow blocks, aerated concrete block walls and reinforced concrete walls, through expansion bolts and U-shaped anchoring parts, so that the phenomena that the traditional outer-wall external thermal insulation rock wool fire barrier belt cracks, falls off, and drops to hurt people due to low bonding strength can be prevented, potential safety hazards in the connection between the traditional outer-wall external thermal insulation rock wool board fire barrier belt and a base course wall can be effectively eliminated, and both the safety and durability of an outer-wall external thermal insulation system can be improved.

Description

technical field [0001] The invention belongs to the field of external thermal insulation of building exterior walls, and in particular relates to a fireproof isolation belt of a steel wire frame rock wool board and a construction method thereof. Background technique [0002] With the development of the construction industry, the installation of fire isolation belts in the external thermal insulation system of high-rise buildings has become an important measure for external thermal insulation and fire protection. However, the current fire isolation belt is usually directly pasted with rock wool boards on the outer wall of the building and assisted by plastic anchors to fix it. This method cannot ensure that the rock wool boards can effectively withstand their own weight and withstand wind pressure, resulting in cracking, falling off and falling injuries of the rock wool boards. The occurrence of the phenomenon of people waiting has affected the service life of the fire isolat...

However, the current fire isolation belt is usually directly pasted with rock wool boards on the outer wall of the building and assisted by plastic anchors to fix it. This method cannot ensure that the rock wool boards can effectively withstand their own weight and withstand wind pressure, resulting in cracking, falling off and falling injuries of the rock wool boards. Occurrence of the human phenomenon affects the service life of the fire isolation zone and the life safety of residents
