Internal corner waterproof construction and construction technology thereof

Abstract

The invention relates to the technical field of waterproof engineering, in particular to an internal corner waterproof construction and a construction technology thereof. The internal corner waterproof construction is formed with a tire body by adopting a special rubber state waterproof coating, the internal corner waterproof construction has the advantages of a waterproof rolling material and a waterproof coating film material, a continuous, complete, defect-free waterproof layer with an excellent waterproof function can be formed on a base plane, an organic whole is formed, good consistencyis achieved, and any leakage and moving are avoided. The internal corner waterproof construction and the construction technology thereof give full play to the characteristics of quick drying, drying rubber from inside to outside and not flowing of the waterproof coating, so that the waterproof construction can be constructed continuously on the basis of maintaining sufficient thickness of waterproof coating without waiting for too long; and finally, the obtained waterproof construction is firmly bonded to the base plane, the waterproof layer is even, integration degree is high, no delaminatingis achieved, and the tensile strength is high.

Description

technical field [0001] The invention relates to the technical field of waterproof engineering, in particular to a waterproof structure of an inner corner and a construction process thereof. Background technique [0002] Building wall construction is one of the important links in building construction, and its construction quality directly affects the use of the building after completion. Among them, the construction of internal corner joints of walls is the most complicated part of wall construction, especially the construction of internal corner joints of non-cast-in-situ and non-masonry walls such as prefabricated panel walls and sandwich panel walls is more complicated . [0003] The construction of internal corner joints such as traditional prefabricated panel walls and sandwich panel walls: firstly, wrapping is made on the outside of the internal corner of the wall, and the package covers the butt joint formed between two wall panels; secondly , fix the two wall panel...

AI Technical Summary

Problems solved by technology

[0004] The traditional construction method of internal corner joints such as prefabricated panel walls and sandwich panel walls, first of all, because the screws directly pass through the wall panels, the screw heads are exposed on the outer facade of the wall, which affects the appearance of the wall on the one hand, On the other hand, the perforated part of the screw is also prone to rainwater leakage; moreover, the butt joint between the two wall panels is a natural cold bridge part and water seepage part, which is simply covered with a package and sealed with a sealing strip. After long-term use, in addition to not being able to play the role of waterproofing and preventing cold bridges, it is easier to make cold bridges and leakage more serious, affecting the normal use of buildings

In short, the traditional construction methods of prefabricated panel walls, sandwich panel walls and other internal corner joints have problems such as exposed screws on the outer facade of the wall, poor waterproof and cold bridge prevention effects, etc.

[0005] At present, affected by practical factors such as the complex structure of concrete and prefabricated panels and the existence of construction defects, there is almost no continuous, complete and defect-free waterproof layer on the building base. If the waterproof layer cannot be sealed and bonded to the building base If the junction is formed, water will seep into between the waterproof layer and the base surface through the damaged part, and flow everywhere at the interface between the two, eventually leading to the failure of the entire waterproof system

And in the construction of the inner corner, the traditional waterproof coating is very easy to drip, and it is easy to cause uneven painting during the construction of the inner corner, and it is difficult to paint thicker at one time, and it needs to be painted repeatedly, and after each brushing for the next painting
