Waterproof structure for joint of exterior wall of fabricated shear wall

Abstract

The invention discloses a waterproof structure for a joint of an exterior wall of a fabricated shear wall. The waterproof structure comprises a horizontal joint structure, comprising a water retainingplate, a water retaining rod, a first outer plugging rod, a first pressure reduction chamber and a drainage channel, a first inner plugging rod, a high-strength non-shrinkage grouting material, a grouting sleeve, a schematic vertical reinforcing steel, a lower prefabricated wall, an upper prefabricated wall, a prefabricated laminated board and a cast-in-situ floor layer, four waterproof measuresincluding construction waterproofing, material waterproofing, construction waterproofing and structure waterproofing being provided from the outside to the inside; and a vertical joint structure, comprising a building sealant, a second outer plugging rod, a second inner plugging rod, a positioning protrusion, a positioning recess, a second pressure reduction chamber and a drainage channel, a leftprefabricated wall, a right prefabricated wall, a cast-in-situ connecting portion and a water-break construction, the second outer plugging rod and the second inner plugging rod being positioned according to the positioning protrusion and the positioning recess. The waterproof performance of the exterior wall of the fabricated building can be improved, the construction efficiency can be effectively improved, and the structure is high in applicability and is simple and easy to implement.

Description

Technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a joint waterproof structure of an outer wall of an assembled shear wall. Background technique [0002] At present, prefabricated buildings refer to buildings assembled from prefabricated components on the construction site. Prefabricated components include prefabricated beams, columns, walls, laminated panels, stairs and other components. Compared with the traditional construction mode, prefabricated buildings require less labor, fast construction speed, slight dust and noise pollution, comfortable working environment for workers, industrial production, and guaranteed quality of components. However, prefabricated buildings are also facing a series of problems, especially the waterproof treatment of external wall joints of prefabricated buildings, which has always been an obstacle to the promotion of prefabricated buildings. [0003] Related technologies include the fol...

Problems solved by technology

For example, the lower cast-in-place part is made into the shape of a discharge slope and a water retaining platform, but it is difficult to operate in the actual construction site. It is often poured into a horizontal shape and then knocked off with tools, which is time-consuming and labor-intensive

[0004] (2) A joint waterproof structure of a load-bearing assembled exterior wall, but it has no clear requirements for the sandwich exterior wall panel for the wall thickness. For the exterior wall with a thinner wall thickness, its structure is difficult to implement, and its waterproof structure is complicated , it is necessary to set the water interception groove, the manufacturing precision is extremely high, and it is difficult to demould, and the current construction technology is difficult to complete the production

Moreover, the pouring height of the cast-in-place slab layer is lower than the top height of the prefabricated reinforced concrete lower exterior wall, which is inconvenient to operate during construction. Similar to the method (1), the cast-in-place layer is easy to be leveled with the top, and tools must be used to remove it. construction difficulties

[0005] (3) Including two kinds of joint waterproof structures of load-bearing assembled exterior walls, but it is only for sandwich exterior walls without clear requirements on wall thickness. The waterproof measures of insulation layer and protective layer are removed, and only one material is left to waterproof And a grouting structure waterproof, no different from the current single-layer prefabricated wall waterproof measures, the waterproof effect is poor, not suitable for thinner load-bearing walls
