Composite wall panel for prefabricated steel structure building and its manufacturing and installation method

Abstract

The invention relates to a composite wallboard for a fabricated steel structure building. The composite wallboard for the fabricated steel structure building sequentially comprises an aerated concreteboard base layer, an interface processing layer, a bonding layer, an insulating layer, a protecting layer and an anti-cracking face layer from bottom to top, wherein the aerated concrete board base layer and the insulating layer are composited together through the interface processing layer and the bonding layer in a bonding manner, the heat preservation mortar protecting layer is poured on the upper surface of the insulating layer, and the insulating layer is completely wrapped by the protecting layer; and the anti-cracking face layer is painted or sprayed to the upper side of the protectinglayer, and the protecting layer, the insulating layer and the aerated concrete board base layer are mechanically anchored together through plastic anchor bolts. According to the composite wallboard for the fabricated steel structure building, the aerated concrete board base layer has the advantages that the manufacturing material source is wide, materials are stable and the like, machinability isgood, the problems of heavy object nailing and hanging on a wall and groove forming and pipeline distributing are solved, and the requirement for the wall thermal performance at cold and severe coldareas is met; and meanwhile, the composite wallboard for the fabricated steel structure building also has the characteristics of being small in weight, low in cost, simple in connection structure, convenient to construct and install and the like and is suitable for an outer wall of the fabricated steel structure building.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a composite wall panel used for a prefabricated steel structure building and a method for making and installing the same. Background technique [0002] Prefabricated steel structure buildings have the advantages of high bearing capacity, good seismic performance, high level of industrialization, and environmental protection, and are an important way to realize the industrialization of buildings. The wall panels currently used in prefabricated steel structure buildings mainly include: autoclaved aerated concrete slabs, prefabricated concrete sandwich exterior wall panels, light steel keel composite wall panels and steel wire grid cement sandwich panels. However, the above four wall panels applied to prefabricated steel structures still have the following technical problems: [0003] 1. With the improvement of building energy-saving design standards, the single ...

Problems solved by technology

[0005] 3. The cold-formed thin-walled steel components of the light steel keel composite wallboard are directly connected to the wallboard, forming a thermal bridge in the wallboard, which affects the thermal insulation and sound insulation effects of the wallboard, and the thickness of the panels on both sides of the wallboard keel is small , usually 9 ~ 15mm, it is difficult to hang heavy objects on the wall

[0006] 4. Since the steel wire grid cement sandwich panel only relies on the extended steel bars in the wall to lift the weight of the cement mortar plastering layer outside the insulation board, the deformation of the steel bars is prone to cause the plastering layer to fall, causing the cement mortar plastering layer to crack. , especially when the insulation layer is thicker, this problem is more prominent

[0007] Due to the above-mentioned problems in the wall panels used in prefabricated steel structure buildings, it affects the popularization and application of prefabricated steel structure buildings and limits the development of building industrialization
