External wall panel for building, assembled external wall panel for building, and construction method of assembled external wall panel

Abstract

The invention provides an external wall panel for building, an assembled external wall panel for the building and a construction method of the assembled external wall panel. In the external wall panel for the building, a bulge and a recess are arranged on a pair of opposite side faces of each external leave wall panel respectively, and are mutually matched; location tightening grooves are formed in the matching surfaces of the bulges and the recesses respectively; the location tightening grooves in the external leave wall panels connected adjacently can be butted to form location through holes; the location through holes are in vertical directions in mounting and operating conditions; the external wall panel in such structure is convenient and quick to mount and construct; the external wall panels are combined and mounted in the horizontal directions and the vertical directions to form the assembled external wall panel; and with the adoption of the external wall panel in the structural form, the assembled external wall panel is simple, convenient and quick to construct.

Description

technical field [0001] The invention relates to an exterior wall panel, in particular to an exterior wall panel for construction, an assembled exterior wall panel for construction and a construction method thereof, belonging to the technical field of construction engineering. Background technique [0002] In the utility model patent with the publication number CN202969710U and the publication date of 2013.06.05, a mortise and tenon type rainproof exterior wall panel is disclosed. A concave plane is formed on the surface of the exterior wall panel close to the side elevation. A plurality of protrusions are arranged at intervals, and the outer surface of the protrusions is recessed on the surface of the exterior wall panel; a concave surface is formed on the other surface of the corresponding exterior wall panel near the other side of the facade, and a plurality of protrusions are arranged at intervals on the concave surface. The depressions formed between adjacent protrusions...

AI Technical Summary

Problems solved by technology

[0003] When the exterior wall panels are installed, two adjacent exterior wall panels are mated with the corresponding concave planes through the protrusions. The problem with this mortise and tenon structure is: there is a fit tolerance between the protrusions and the concave plane, and the fit tolerance On the one hand, it is not easy to adjust the flatness of the exterior wall panels, increasing the difficulty of installation and construction, and reducing the efficiency of construction; In order to make the exterior wall panel waterproof, it is necessary to set water guide grooves on both the convex block and the concave surface, through which the water will be automatically diverted and removed to prevent water from entering the wall. The construction process, and its waterproof performance is not good, can not guarantee that the water can be completely excluded, this is the deficiency of the existing technology
