Prefabricated non-thermal bridge external thermal insulation wallboard with C-shaped steel light steel keel and manufacturing method thereof

Abstract

The invention relates to a prefabricated non-thermal bridge external thermal insulation wallboard with a C-shaped steel light steel keel and a manufacturing method thereof. The wallboard comprises a base wall body, a break thermal bridge anchoring bolt, a connecting piece, a thermal insulation board and a stressed-skin diaphragm. The thermal insulation board and the base wall body are fixedly connected into a whole through the break thermal bridge anchoring bolt and the connecting piece, and the stressed-skin diaphragm is fixedly arranged on the other side, relative to the thermal insulation board, of the base wall body. The prefabricated non-thermal bridge external thermal insulation wallboard is convenient to construct and simple in structure, breaks the inherent concept of ''thermal insulation after wall body'' and proposes the integrated production of a thermal insulation wall body. Factory prefabrication and site assembly can be carried out, batch production and on-site installation are convenient, the construction efficiency is improved, the characteristics of low energy consumption, flexible arrangement and fast construction are achieved, and the requirements of green construction are met. The arrangement of the non-cut-through type break thermal bridge anchoring bolt and dovetail grooves avoids the phenomenon of a thermal bridge caused by joints and the like, the thermal insulation performance of the wall body is improved, and the structural integrity is increased; and the weight of the wall body is greatly reduced due to using of a light steel keel frame and lightweight concrete, and the cost of construction, transportation and seismic design of later structure is reduced.

Description

Technical field: [0001] The invention relates to the technical field of construction engineering, in particular to a C-shaped steel light steel keel prefabricated non-thermal bridge external thermal insulation wallboard and a manufacturing method thereof. Background technique: [0002] With the rapid development of cities, building energy consumption is increasing year by year, and more and more prefabricated buildings and green construction methods have been put on the agenda. As a key industry for national sustainable development, the building energy-saving industry is an important way to achieve national energy security. The prefabricated passive house is a new type of house with prefabricated concrete components as the enclosure structure, good thermal insulation effect and air tightness, high indoor comfort, and does not use active heating technology. Whether it is from the construction period and construction quality of the house, or from the perspective of the indoor ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a C-shaped steel light steel keel prefabricated heat-bridge-free external thermal insulation wallboard and its manufacturing method, which are convenient to build and simple in structure, and solve the problem of thermal bridges caused by seams and the like. The setting of non-through heat break bridge anchor bolts and dovetail grooves not only strengthens the thermal insulation performance of the wall, but also improves the efficiency of prefabricated industrial production, effectively reduces the energy consumption of buildings, and realizes green construction
