Dry hanging self-decoration anti-seepage insulation board for external wall

Abstract

The invention discloses a dry hanging self-decoration anti-seepage insulation board for an external wall. The insulation board comprises a panel and an insulation layer, wherein at least two side edges of the insulation layer are wider than the corresponding side edges of the panel by 1-2 mm, and anti-seepage bulges or / and anti-seepage grooves are formed in the side surfaces of the insulation layer; the insulation board has the advantages that 1, a structural form that side surfaces of the insulation layer press mutually and the anti-seepage bulges and the anti-seepage grooves in the side surfaces are mutually embedded, water seepage is effectively prevented; bonding waterproof layers are arranged among the side surfaces of the insulation layer and between the anti-seepage bulges and the anti-seepage grooves, and particularly, a flexible caulking compound is embedded into a board seam with the width of only about 3 mm between protection layers, so that the water seepage is prevented from the material. 2, the installation manner is simple, firm and reliable. The installation manner of main anchoring and auxiliary bonding is adopted, and an insulation protection layer and a wall body are ensured to be combined densely, firmly and reliably. 3, insulation protection of wall surface and the board seam, waterproof anti-seepage and wall decoration are completed simultaneously, the construction period is shortened greatly, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials, and more specifically relates to a dry-hanging self-decorating impermeable external wall thermal insulation board. Background technique [0002] There are many kinds of existing dry-hanging external wall insulation boards, and the basic structure is all made up of panels and insulation layers of equal area. There are the following defects: poor waterproof and anti-seepage performance of board seams and high cost. The side of this type of insulation board is flat, and after installation, a board seam about 15mm wide is formed. During the construction of the board seam, the insulation strip is first placed in the board seam, and then the seam is filled with caulking material. The on-site installation of the insulation board can not guarantee the 15mm wide board seam spacing at all, and the error is generally about 2mm, which leads to the gap between the insulation strip in the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that the existing dry-hanging external wall insulation board lacks anti-seepage function and water leakage, and provides a dry-hanging self-decorating anti-seepage external wall insulation board
