Building external wall panel waterproof structure and waterproof construction method

Abstract

The invention relates to a building external wall panel waterproof structure and a waterproof construction method.The building comprises external wall panels and internal wall panels, the external wall panels are laid on the outer surfaces of the internal wall panels, the multiple external wall panels and waterproof assemblies and enclosure assemblies are arranged between the adjacent external wall panels, and the waterproof assemblies surround the peripheries of the external wall panels; the enclosure assembly is used for connecting the adjacent waterproof assembly and the external wall panel, the waterproof assembly comprises an upper clamping piece, a lower clamping piece, a left clamping piece and a right clamping piece which are arranged along the periphery of the external wall panel, the upper clamping piece, the lower clamping piece, the left clamping piece and the right clamping piece are connected through first connecting pieces to form a frame for a window plate to be clamped in, and the frame is provided with a drainage diversion trench. When water permeates from the space between the enclosure assembly and the waterproof assembly, the water flows into the flow guide groove and is discharged along the flow guide groove, so that integral water prevention is formed.

Description

technical field [0001] The invention relates to a waterproof structure and a waterproof construction method for building exterior wall panels. Background technique [0002] The energy consumption in the construction industry accounts for almost 30% of the total energy consumption, the steel consumption in the construction industry accounts for 50% of the total social steel consumption, and 1.5 billion to 2.4 billion tons of construction waste is generated every year. At the same time of high resource energy consumption, serious environmental pollution and high labor intensity have existed in the construction industry for a long time. The country has begun to advocate and develop prefabricated buildings. Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods. It is carried out in the factory, and the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed i...

AI Technical Summary

Problems solved by technology

[0003] Whether it is a prefabricated building method or a traditional building method, the problem of water leakage in the building cannot be avoided, especially in the south where it rains for a long time, the water leakage problem will cause damage to the building and affect people's lives; for prefabricated buildings Because the prefabricated wall panels are processed in the industry, they are transported to the construction site to install the wall panels and wall panels into complete wall panels. Because there are gaps between the wall panels and the gaps are not handled properly, it is easy to cause water to flow from the gaps. Infiltration, at the same time, there are no effective measures to deal with the water infiltration from the gap, and it is easy to cause the wallboard to rot due to the long-term infiltration of water
