Externally-hung wallboard manufactured by compounding light steel keels and wood wool slabs, and manufacturing method of externally-hung wallboard

Abstract

The invention relates to an externally-hung wallboard manufactured by compounding light steel keels and wood wool slabs, and a manufacturing method of the externally-hung wallboard. The externally-hung wallboard comprises a light steel keel skeleton, the wood wool slabs and foam concrete, wherein the light steel keel skeleton has a fence structure formed by a plurality of vertical keels and horizontal through keels; the wood wool slabs are respectively connected with the two sides of the surface of the light steel keel skeleton, so that a wallboard structure is formed; the parts between the light steel keel skeleton and the wood wool slabs are filled with the foam concrete, and the externally-hung wallboard is formed after the foam concrete is solidified. Compared with the prior art, the externally-hung wallboard has the advantages that the wallboard is low in manufacturing cost and environmentally-friendly in materials; the wallboard has excellent functions of heat preservation, heat insulation and noise absorption; the externally-hung wallboard is light in structure, high in rigidity, firm and durable; the externally-hung wallboard is simple in construction and low in hoisting requirement; the surface of the wallboard has a waterproof function and is corrosion-resistant.

Description

technical field [0001] The invention relates to an external wall panel component, in particular to an external wall panel of a light steel keel composite wood wool board and a manufacturing method thereof. Background technique [0002] The light steel keel cladding wall is generally used as a lightweight partition wall, which is assembled on site, and the keel is filled with mineral wool or glass wool, etc., and the cladding panels are generally paper-faced gypsum boards. A few companies have developed light steel keel cladding walls for exterior walls. For example, STO’s exterior wall panels are composed of light steel keels + gypsum boards + polymer foam + plastering and finishes; Baosteel Construction released a new generation at the end of 2014. Prefabricated steel structure century-old system - Baohouse, launched "Baosteel thermal insulation and decoration integrated board", which is a prefabricated lightweight sandwich composite exterior wall panel, filled with 100mm t...

AI Technical Summary

Problems solved by technology

The above-mentioned composite wallboards have many shortcomings. The lightweight wallboards that use polymer foam, mineral wool or glass wool as thermal insulation materials have poor thermal insulation and thermal insulation performance of the wall, and the space board does not use cladding boards.

[0003] Wood wool board is a kind of building board made of fast-growing forest as the main raw material. It has excellent environmental friendly characteristics. As an important sound-absorbing material and heat insulation material, it has been widely used since the 1950s and 1960s. The interior of the building is filled with walls, and has the environmental performance of low cost and secondary use of materials. However, ordinary wood wool boards cannot be well connected with building facades due to insufficient local strength, and have not been applied to external wall panels on building facades. precedent
