Tooth-groove type waterproof connecting structure adopting pressure-grouting method for horizontal joints of assembling type building prefabricated wall boards

Abstract

The invention discloses a tooth-groove type waterproof connecting structure adopting a pressure-grouting method for horizontal joints of assembling type building prefabricated wall boards. The tooth-groove type waterproof connecting structure comprises assembling type prefabricated wall boards and assembling type building bottom boards and assembling type building top boards connected with the assembling type prefabricated wall boards, wherein lower trapezoidal grooves are prefabricated at the positions of the assembling type building bottom boards connected with the assembling type prefabricated wall boards; upper trapezoidal convex teeth are prefabricated at the positions of the assembling building top boards connected with the assembling type prefabricated wall boards; lower trapezoidalconvex teeth corresponding to the lower trapezoidal grooves are prefabricated on the connecting surfaces corresponding to the assembling type prefabricated wall boards and the assembling type building bottom boards; upper trapezoidal grooves corresponding to the upper trapezoidal convex teeth are prefabricated on the connecting surfaces corresponding to the assembling type prefabricated wall boards and the assembling type building top boards; a certain amount of waterproof mortar is preset in the upper trapezoidal grooves and the lower trapezoidal grooves. The tooth-groove type waterproof connecting structure disclosed by the invention has the beneficial effects that the flexible waterproof mortar is reliably used for filling the horizontal joints of the prefabricated wall boards and building boards, the phenomena of water seepage and water accumulation of the assembling type building outer wall surfaces are effectively improved, and the traditional process of the connecting structures of the assembling type prefabricated wall boards and the building boards is optimized, so that the tooth-groove type waterproof connecting structure can be widely applied to the prefabricated assembling type wall board structures and cast-in-situ composite building board structures.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a horizontal seam grouting method alveolar waterproof connection structure of an assembled building prefabricated wallboard. Background technique [0002] Prefabricated concrete structure refers to the standardized production of various components of the structure, including prefabricated shear walls, prefabricated beams, prefabricated columns, prefabricated floors, prefabricated wall panels, etc., and then the prefabricated components are bolted and welded at the construction site. A structure formed by connection or cast-in-place connection installation. The industrial production of each prefabricated component of the prefabricated concrete structure has the advantages of saving labor force, fast construction progress, helping to realize building energy conservation, facilitating industrial production and mechanized construction, etc., and adapting ...

AI Technical Summary

Problems solved by technology

[0003] The seam between the prefabricated prefabricated wall panel and the laminated floor is a horizontal joint. The commonly used waterproof structure is to set an anti-sill structure at the joint between the laminated floor and the wall panel, and lay a certain thickness of flexible waterproof mortar on the anti-sill. The two are connected, this method cannot ensure the flatness of the mortar and may cause the wall panel to tilt in the vertical direction, and the mortar cannot fill the entire joint, resulting in weak integrity of the connection between the prefabricated wall panel and the laminated floor slab, and cannot Effectively prevent the infiltration of rainwater, the waterproof effect is not obvious, and it is easy to generate water accumulation at the joint joints, and the construction process consumes a lot of manpower
