Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building exterior wall waterproofing, in particular to a building exterior wall waterproofing structure. Background Art
[0002] External wall waterproofing is a waterproofing project in construction projects that ensures that the building structure is not invaded by water. External wall waterproofing occupies an important position in the entire construction project. External wall waterproofing mainly relies on three lines of defense, namely external wall paint, plaster mortar and structural wall. Sometimes waterproof mortar is added to the outermost layer of the wall to enhance the waterproof effect. Waterproof mortar can effectively reduce the corrosion and penetration of rainwater or other moisture into the interior of the wall and prevent mold on the inner wall. However, in the construction of the external wall of the prefabricated building, the flatness of the prefabricated external wall is better, and the plaster mortar process can be exempted from the building facade.
[0003] Due to the structural characteristics and construction technology, the contact positions between the prefabricated components of the exterior walls of assembled buildings are the most prone to moisture penetration. This is because stress gaps are most likely to occur here, so rainwater will enter the wall through the gaps, causing the exterior wall to become damp. Based on this, a building exterior wall waterproof structure is proposed to solve the above problem. Utility Model Content

By using this scheme, it is convenient to provide an installation position for the second waterstop, and at the same time it is convenient to splice multiple waterproof components in the vertical direction, and the second waterstop is compressed by its own gravity to avoid water seepage.
[0007] Preferably, any of the above schemes has a U-shaped shape at the top end of the arc-shaped protrusion, and its size after being combined with the first waterstop is compatible with the size of the arc-shaped groove. By using this scheme, when two waterproof parts are spliced, the first waterstop is wrapped around the outside of the arc-shaped protrusion and enters into the inside of the arc-shaped groove, thereby sealing the docking position of the two adjacent waterproof parts once. At the same time, after the two adjacent waterproof parts are docked, the hollow water-blocking part is pressed, and at the same time, the elastic force of multiple springs is cooperated to make the two support bars move in opposite directions, squeeze the two side positions of the hollow water-blocking part, and perform a secondary sealing on the splicing position of the two waterproof parts.
