A prefabricated double-layer exterior wall panel and its installation structure and horizontal and vertical waterproof structure

Abstract

The invention provides an assembled double-layer external wallboard, which comprises an inner composite wallboard, a steel framework and an outer composite wallboard, wherein the inner composite wallboard and the outer composite wallboard are arranged to form a structure with the higher inner part and the lower outer part in the height direction; the height difference of the inner composite wallboard and the outer composite wallboard is not smaller than 10mm; the steel framework is arranged between the inner composite wallboard and the outer composite wallboard; the steel framework is formed by welding square steel; the square steel are in through-length arrangement along the periphery of the inner and outer composite wallboards; a plurality of screw holes are correspondingly formed in theinner and outer composite wallboards and the square steel; the distance from the screw bolt holes to the edge of the inner and outer composite wallboards is not smaller than 100mm; first stainless steel screw bolts for connecting and fixing the inner and outer composite wallboards and the square steel are arranged in the screw bolt holes in a penetrating way; and gaskets attached to the inner andouter composite wallboards arranged on the first stainless steel screw bolts in a sleeving way. The invention also provides an installing structure, a horizontal waterproof structure and a vertical waterproof structure of the assembled double-layer external wallboard. The assembled double-layer external wallboard provided by the invention has the characteristics that the weight is light; the environment is protected; the energy is saved; and the construction speed is high. The installation is convenient; and the waterproof structure has good waterproof performance.

Description

technical field [0001] The invention relates to the technical field of building exterior walls, in particular to an assembled double-layer exterior wall panel, an installation structure and a horizontal and vertical waterproof structure. Background technique [0002] Under the current domestic background, prefabricated buildings are the general trend of current building development. Prefabricated buildings have the characteristics of green, energy saving, and environmental protection. Strengthening the research on prefabricated buildings and vigorously developing prefabricated buildings are of great significance to protect the ecological environment in which we live. [0003] The inventors of the present invention have found through research that at present, the research on prefabricated buildings is more concentrated on the structural components of the main structure, such as beams, columns, shear walls, etc., while there is little research on the exterior walls of the pref...
