Abstract

The invention provides a prefabricated light compound insulation wallboard as well as a mounting method thereof, and belongs to the technical field of building energy conservation. The prefabricated light compound insulation wallboard comprises an outer wallboard, a thermal insulation layer and an inner wallboard from outside to inside in sequence, wherein the outer wallboard and the thermal insulation layer are connected through a steel bar truss, and the thermal insulation layer and the inner wallboard are bonded by pressing; the outer wallboard is made of concrete, and the thermal insulation layer is made of a light insulation material; connecting parts connected with the steel bar truss are arranged between the outer wallboard and the thermal insulation layer. The invention provides amanufacturing method and the mounting method of the prefabricated light compound insulation wallboard. The manufacturing method comprises following steps: prefabricating the outer wallboard and the thermal insulation layer; pre-embedding the steel bar truss; pre-embedding U-shaped connecting pieces; laying the thermal insulation layer; compounding the inner wallboard and the thermal insulation layer. The mounting method comprises following steps: connecting L-shaped connecting pieces with the U-shaped connecting pieces through bolts; welding the L-shaped connecting pieces and a main structureof a building; blocking gaps. The prefabricated light compound insulation wallboard is light, thermal-insulating and sound-insulating, has universality, is widely applied, simple in structural connection and rapid to mount and facilitates industrial production.

Description

technical field [0001] The invention relates to an assembled lightweight composite thermal insulation wallboard, a manufacturing method and an installation method thereof, and belongs to the technical field of building energy conservation. Background technique [0002] At present, there are mainly two structural forms in the domestic industrialized prefabricated concrete laminated wall panel structure. The first type of laminated wall panel is single-layer laminated, that is, the outdoor part is prefabricated in the factory, the indoor part is molded on site, and the middle is used. Concrete is poured on site. Although this construction method reflects the advantages of prefabricated concrete structures to a certain extent, the degree of industrial assembly is not high. The second type of laminated wall panel is a double-layer laminated wall panel without thermal insulation structure, that is, both the outdoor and indoor parts are prefabricated in the factory, and the middle...

Problems solved by technology

[0002] At present, there are mainly two structural forms in the domestic industrialized prefabricated concrete laminated wall panel structure. The first type of laminated wall panel is single-layer laminated, that is, the outdoor part is prefabricated in the factory, the indoor part is molded on site, and the middle is used. Concrete is poured on site. Although this construction method reflects the advantages of prefabricated concrete structures to a certain extent, the degree of industrial assembly is not high.

The second type of laminated wall panel is a double-layer laminated wall panel without thermal insulation structure, that is, both the outdoor and indoor parts are prefabricated in the factory, and the middle part is poured on site with concrete. This construction method can largely reflect the prefabricated prefabrication The advantages of concrete structure, but because the prefabricated part of the indoor and outdoor factory is the stress unit of the main structure in design principle, limited by the production process and the force requirements, the prefabricated part cannot consider the wall insulation layer

[0003] In addition, the third type of wall panel structure is an industrially assembled prefabricated concrete solid wall panel structure, that is, a fully solid concrete wall panel. The connecting part adopts a pre-embedded grouting sleeve, and the cement grouting material is poured on site to anchor and connect the inserted ribs; Compared with the above-mentioned laminated wall panels, the construction method reduces the on-site pouring process between the double-layer laminated panels, but according to the existing regulations, the thickness of the industrially assembled prefabricated concrete solid wall panels must be ≥ 200mm, not only self-heavy, hoisting Difficult, but also have high requirements for production (embedded) and construction precision

[0004] In view of the above, if the existing precast concrete-related exterior wall panels are to be applied to the field of low-rise buildings, there are generally problems such as high production accuracy requirements, heavy weight, high cost, insufficient heat preservation, and difficult construction. The thickness of the wallboard is basically fixed, and the adaptability to different climatic environments is insufficient
