Prefabricated reinforced concrete composite heat-preservation outer wall plate and manufacturing and installation method thereof

Abstract

The invention provides a prefabricated reinforced concrete composite heat-preservation outer wall plate and a manufacturing and installation method thereof. The prefabricated reinforced concrete composite heat-preservation outer wall plate comprises a heat-preservation plate body and a prefabricated reinforced concrete wall plate body which is installed on the heat-preservation plate body; and a plurality of installation protruded blocks are installed on the end face, facing the prefabricated reinforced concrete wall plate body, of the heat-preservation plate body, and installation grooves matched with the protruded blocks are formed in the prefabricated reinforced concrete wall plate body. The installation method comprises the following steps that a steel plate is welded onto an upper wing and a lower wing of a steel girder on a to-be-constructed wall face correspondingly; and the prefabricated reinforced concrete heat-preservation wall plates are fixed to the upper wing and / or lower wing of the steel girder through bolts. According to the prefabricated reinforced concrete composite heat-preservation outer wall plate and the manufacturing and installation method thereof, the prefabricated reinforced concrete wall plate body is combined with the heat-preservation plate body, and part of the heat-preservation plate body is embedded into the concrete wall plate body, so that the weight of the concrete wall plate body is reduced, the strength, the rigidity and the using function of the concrete wall plate body are not lowered, the installation technique is simple, and operation is convenient.

Description

technical field [0001] The invention belongs to the field of thermal insulation walls, in particular to a prefabricated reinforced concrete composite thermal insulation exterior wall panel. Background technique [0002] With the vigorous promotion of prefabricated buildings, although the prefabricated building structure system, building parts system and technical standard system have been initially established, none of the systems have cultivated main products with market competitiveness, especially the exterior walls of building parts. Due to the harsh external environment, there are strict requirements for strength, rigidity and safety in use, and there is no new type of wall material that dominates the market. The traditional reinforced concrete exterior wall has disadvantages such as heavy hoisting weight and difficulty in on-site assembly. The external insulation system needs to use glue and connectors to fix the insulation board. It is not suitable for prefabricated c...

AI Technical Summary

Problems solved by technology

The traditional reinforced concrete exterior wall has disadvantages such as heavy hoisting weight and difficulty in on-site assembly. The external insulation system needs to use glue and connectors to fix the insulation board. It is not suitable for prefabricated construction; there is another sandwich exterior wall panel with the insulation layer placed in the middle. On the one hand, it is thick and heavy, which is not conducive to hoisting. On the other hand, the thickness of the insulation is restricted, and it is difficult to meet the requirements of energy-saving standards.
