Waterproof structure at abutted seam of prefabricated light-steel keel composite wallboards

Abstract

The invention relates to a waterproof structure at an abutted seam of prefabricated light-steel keel composite wallboards. The waterproof structure is arranged at the abutted seam of the light-steel keel composite wallboards. The waterproof structure is a cavity waterproof structure; a sealing box body is arranged inside the cavity waterproof structure; an opening provided with an edge is arrangedat the upper part of the sealing box body; the edge of the upper part of the sealing box body and the abutted seam of the light-steel keel composite wallboards are sealed by a sealant; the sealing box body is filled with PE foam sticks via the opening, and screeding is performed, so that the opening at the upper end of the sealing box body is blocked; and the lower end of the sealing box body isfixedly connected with profiled steel sheets of the light-steel keel composite wallboards through connecting pieces. According to the waterproof structure, the waterproof problems that outdoor rainwater permeates along the seams at the horizontal abutted seams and vertical abutted seams of the prefabricated external wallboards are well solved, and on the premise that the waterproof performance isguaranteed, the overall strength of the wallboard structures cannot be reduced.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to an assembled waterproof structure for joints of light steel keel composite wallboards. Background technique [0002] Prefabricated housing is the development trend of the construction industry. The prefabricated composite wall panel is produced by factory, and then transported to the site for hoisting, so as to realize standardization and industrialization, improve construction efficiency and realize green building. However, after the prefabricated external wall panels are installed, waterproof treatment should be carried out on the joints to prevent rainwater from seeping into the room along the joints of the external wall panels. At the same time, if the water seepage is serious, the steel parts will be corroded and loose, and the structural bearing capacity will be reduced. , bringing serious hidden dangers to the project.
