Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building materials, and particularly relates to a connecting structure of a waterproof aluminum wallboard for building. BACKGROUND

[0002] At present, there are various new wall building materials on the market, among which are aluminum wallboards. The existing aluminum wallboard structure is formed by shearing aluminum alloy plates, and the side edges are pressed to form folded edges, which are then fixed on the metal furring of the wall through bolts. The disadvantage of this structure is that the aluminum alloy plate is not an extruded wallboard structure, and the back of the wallboard is not reinforced, so that the overall compressive strength is not high enough, and the wallboard is prone to deformation after long-term use. When used in a wide wall, the large-area aluminum wallboard is also prone to deformation. The splicing joint between the aluminum wallboards is filled and smoothed with waterproof glue, which requires long working time and high process requirements. The aluminum wallboards are not connected, which not only prolongs the installation time, but also reduces the overall structural strength after splicing. When used in a sun corner wall structure or a shadow corner wall structure, the plate is only fixed on the furring of the wall corner, and the strength of the plate at the wall corner is not high enough, so that the aluminum wallboard is not stable enough.
