Structural heat-preservation decoration integrated large-size prefabricated outer wall-hung plate and manufacturing method thereof

Abstract

The invention discloses a structural heat-preservation decoration integrated large-size prefabricated outer wall-hung plate and a manufacturing method thereof. The structural heat-preservation decoration integrated large-size prefabricated outer wall-hung plate comprises a plate body, wherein the plate body consists of a reinforced concrete surface layer and a heat-preservation layer which are compounded together from outside to inside; embedded parts are pre-buried into the plate body; a surface layer reinforced net is paved inside the reinforced concrete surface layer; a layer of heat-preservation layer reinforced net is paved inside the heat-preservation layer; truss reinforcing steel bars are connected between the surface layer reinforced net and the heat-preservation layer reinforced net; lower chord reinforcing steel bars of the truss reinforcing steel bars are fixedly connected with the surface layer reinforced net; the upper chord reinforcing steel bars of the truss reinforcing steel bars are buried in the heat-preservation layer; grooves and tongues for matching connection are respectively formed in the upper and lower ends of the wall plate. Due to adoption of the reinforced concrete surface plates and cement-based material heat-preservation layers with self-heat-preservation property, the wall plate is simple in structure, convenient to manufacture, low in cost, light in self-weight, convenient to mount and applicable to construction of direct outer pre-hung wall plates in a whole open room, can be produced on ordinary wall plate production lines, integrates structure, heat-preservation and decoration, and can be directly hung on a construction main body structure without being assembled again or paving keels.

Description

technical field [0001] The invention belongs to the technical field of reinforced concrete structure engineering, in particular to a large-scale prefabricated external hanging wallboard integrated with structural heat preservation and decoration and a manufacturing method thereof. Background technique [0002] At present, the types of prefabricated external wall panels mainly include wall panels with organic materials such as EPS, XPS or benzene panels as insulation layers and wall panels with inorganic materials as insulation layers, such as autoclaved aerated concrete wall panels and foam concrete wall panels. Wait. [0003] Among them, the composite exterior wall panels with organic materials as the insulation layer have problems: the organic materials have low strength and poor durability, and thicker concrete substrates and panels are required to bear the load and protect the organic insulation materials, resulting in a large weight per unit area; The expansion coeffic...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a large-scale prefabricated external wallboard with integrated structure, thermal insulation and decoration and its manufacturing method, so as to solve the problem that there are organic or inorganic materials in the prefabricated wallboard at the same time. Make the external medium enter the organic layer from the cracks, resulting in reduced durability or the problem of inorganic wallboards; it also solves the problem of poor thermal insulation performance and low strength of existing prefabricated inorganic wallboards, which cannot be directly hung on the main structure, and can only be built by masonry or The technical problem of splicing and hanging or using additional keels to connect into a whole; in addition, it also solves the problem that the existing prefabricated wallboard products generally need to be made in a special manufacturer, and the ordinary equipment of the precast concrete component factory cannot be used, and need to be customized according to the requirements of different engineering drawings Technical problems with cumbersome production and production processes and high technical requirements
