External wall insulation board and manufacturing method thereof

Abstract

The invention discloses a thermal insulation board for an outer wall, which is characterized in that it comprises a thermal insulation piece, a truss and a transverse bar. The insulation part is perlite insulation board or cement foam insulation board. There is one group of trusses, each truss has the same structure, each truss is arranged parallel to each other, and is vertically arranged along the length direction of the thermal insulation part. The thermal insulation parts are pressed on each truss, and the upper and lower ribs of each truss are located outside the thermal insulation parts. There are several transverse ribs, and each transverse rib is arranged parallel to each other, and is all arranged along the width direction of the thermal insulation part. Each transverse rib is welded and fixed on the upper and lower ribs of each corresponding truss at intervals.

Description

technical field [0001] The invention relates to the construction field, in particular to a perlite insulation board or a foamed cement insulation board used for building exterior walls and a manufacturing method thereof. Background technique [0002] Perlite insulation board is light in weight and has excellent thermal insulation performance. Fireproof, moisture-proof, non-deformable, non-rotten and moldy, non-toxic and tasteless, and has good hydrophobicity, with a water-repellent rate of over 98%, so it is widely used in walls and roofs of residential, industrial, and public buildings. Swimming pool, cold storage, boiler and some thermal insulation projects with special requirements for waterproofing. At present, the annual output of perlite external wall insulation board in my country has exceeded 6 million cubic meters, accounting for about 7% of the annual output of insulation materials in my country. It is the most widely used type of lightweight insulation material i...

AI Technical Summary

Problems solved by technology

[0004] Both the above-mentioned perlite insulation board and cement foam insulation board are brittle, easy to break, and have low tensile strength. The maximum size during production and processing can only be 1 meter long, which leads to low production efficiency and greatly Increased workload during installation and use

There are also some external wall insulation boards that embed corrugated steel wires and metal reinforcement bars in the board body (also called insulation), but only one side of them will be exposed outside the board body, and the corrugated steel wires and metal reinforcement bars are easily damaged during the pressing process. Compression deformation, the yield is too low
