Problems solved by technology

ALC autoclaved lightweight concrete wall panels have been promoted and applied due to their excellent thermal insulation, fire resistance and ease of construction. At present, they are widely used as interior wall partitions, steel beams and steel columns with fire protection panels, but as an assembly Type components, due to the defects of easy leakage at the panel interface, poor stability of connection nodes with the cast-in-place structure and poor seismic performance in the traditional construction technology, there are great limitations when used as an external enclosure structure

Abstract

The invention relates to a construction method for an ALC (Autoclaved Lightweight Concrete) board for an external wall panel. The method comprises the following steps: S1, an ALC board is transportedto a to-be-constructed site; S2, after the mounting position of the ALC board is determined at the to-be-constructed site, angle steel for fixing the ALC board in the first step is mounted; S3, aftera fastener is mounted on the ALC board in the first step, the ALC board is hoisted to the angle steel mounting position in the second step, and the fastener on the ALC board and the angle steel are fixedly mounted; and S4, anti-seepage treatment is carried out on the gap between adjacent two ALC boards in the third step. In comparison with the prior art, according to the construction method for the ALC board for the external wall panel provided by the invention, as a prefabricated ALC board is transported to the site, the ALC board is provided with the fastener and is then fixed with the anglesteel after fixing, and the ALC board fixing stability is enhanced; and as anti-seepage treatment is added to the gap between adjacent boards, the anti-seepage performance of the ALC board for the external wall panel is improved, and the applicability of the ALC prefabricated board is effectively improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated ALC construction, and more specifically relates to a construction method of an ALC panel used for exterior wall panels. Background technique [0002] ALC is the abbreviation of Autoclaved Lightweight Concrete, which is a kind of high-performance autoclaved aerated concrete (ALC). ALC board is a porous concrete forming board (including treated steel reinforcement) made of fly ash (or silica sand), cement, lime, etc. as the main raw materials, and cured by high-pressure steam. ALC autoclaved lightweight concrete wall panels have been popularized and applied due to their excellent thermal insulation, fire resistance and ease of construction. At present, they are widely used as interior wall partitions, steel beams and steel columns with fire protection panels, but as an assembly Due to the defects of easy leakage at the panel interface, poor stability of joints connected with the cast-in-place...
