External wall insulation sandwiched casing mold fireproof wallboard for building wall

Abstract

The invention discloses an external wall insulation sandwiched casting mold fireproof wallboard for a building wall. The external wall insulation sandwiched casting mold fireproof wallboard is composed of a surface fireproof insulation layer, an intermediate insulation core, strengthening steel nets and fixing supporting frames. The strengthening steel nets are rectangular. The rectangular intermediate insulation core is arranged between the two layers of strengthening steel nets. A steel wire is arranged and connected between the two layers of strengthening steel nets through the intermediate insulation core so that the two layers of strengthening steel nets and the intermediate insulation core can be connected into a platy inner framework whole. At least four pairs of fixing supporting frames are symmetrically arranged above and below the two layers of strengthening steel nets. The periphery of the intermediate insulation core is provided with the platy surface fireproof insulation layer wrapping the strengthening steel nets and the fixing supporting frames inside. The pressure-holding casting mold technology is utilized, after construction, the external wall insulation casting mold fireproof wallboard is tightly attached to the wall, light concrete of the wallboard is consistent with that of the building wall, deformation is not liable to happen, cracking and falling are avoided, the weight of the insulation layer is also lowered, and meanwhile strength is improved and the combustion-resisting fireproof effect is good.

Description

technical field [0001] The invention relates to a thermal insulation material for the external wall of a building, in particular to a fire wall panel of a sandwich casting mold for thermal insulation of the external wall of a building wall. Background technique [0002] At present, as the country has higher and higher requirements for building energy conservation, the thermal insulation performance indicators of building materials are gradually being paid attention to. With the strong support of national policies, new thermal insulation and energy-saving materials are developing rapidly, and the demand for lightweight thermal insulation wall materials is increasing. bigger. At present, the existing building insulation methods mainly include the technology of adding thin mortar coating to the insulation layer. This method is to directly fix the insulation materials such as extruded plastic board and expanded polystyrene board on the building wall after the construction is com...

Problems solved by technology

At present, the existing building insulation methods mainly include the technology of adding thin mortar coating to the insulation layer. This method is to directly fix the insulation materials such as extruded plastic board and expanded polystyrene board on the building wall after the construction is completed. , and then use cement mortar to smear the surface, and finally complete the wall insulation of the building. The existing wall insulation technology has disadvantages such as the need for secondary construction, poor fixing strength of the insulation material, easy to fall off, and short service life. There are serious fire hazards in this construction process. In the event of a fire accident, the thermal insulation material of the outer wall of the wall cannot play a role in fire prevention.
