Description
Technical Field
The invention belongs to the technical field of constructional engineering, and particularly relates to a tooth socket type waterproof connecting structure of an assembled building prefabricated wallboard by a horizontal joint grouting method.
Background
The prefabricated assembled concrete structure refers to a structure formed by carrying out standardized production on various components of the structure including prefabricated shear walls, prefabricated beams, prefabricated columns, prefabricated floors, prefabricated wallboards and the like in engineering, and then installing the prefabricated components on a construction site through bolt connection, welding connection or cast-in-situ connection. The prefabricated components of the fabricated concrete structure are produced industrially, and the prefabricated concrete structure has the advantages of saving labor force, being fast in construction progress, being beneficial to realizing building energy conservation, being convenient for industrial production and mechanized construction, and the like, and is suitable for the development direction of building industrialization in China. However, a large number of splicing seams exist in the assembled structure, splicing seam leakage is easy to occur at the horizontal seam of the wallboard and the composite floor slab, and meanwhile, the difficulty of leakage treatment of the assembled wallboard is greatly increased due to the difficult repairability of the composite heat-insulating wallboard. Therefore, the waterproof key of the assembled building is the sealing waterproof of the horizontal splicing seam of the prefabricated wall boards and the composite floor slab.
The assembly type prefabricated wallboard and the composite floor slab are horizontally jointed, the common waterproof structure is that a reverse ridge structure is arranged at the joint of the composite floor slab and the wallboard, and flexible waterproof mortar with a certain thickness is paved on the reverse ridge to connect the two.
Disclosure of Invention

In order to achieve the above purpose, the present invention adopts the following technical scheme:
the utility model provides a prefabricated wallboard horizontal joint mud jacking method tooth's socket formula waterproof connection structure of assembled building, includes prefabricated wallboard and the assembled floor board and the assembled roof board that are connected with prefabricated wallboard, assembled floor board prefabricates in the position of connecting prefabricated wallboard has trapezoidal protruding tooth down, assembled roof board prefabricates in the position of connecting prefabricated wallboard has trapezoidal protruding tooth down, prefabricated wallboard and the connection face that assembled floor board corresponds are prefabricated have with trapezoidal protruding tooth down that trapezoidal groove corresponds, prefabricated wallboard and the connection face that assembled roof board corresponds go up trapezoidal groove that trapezoidal protruding tooth corresponds, upward, preset a certain amount of waterproof mortar in the trapezoidal groove down, make assembled roof board pass through prefabricated wallboard on the back down from the top down, go up between trapezoidal protruding tooth and the trapezoidal recess of trapezoidal protruding tooth down and all form the waterproof mortar layer of one deck full seam between the trapezoidal recess down. After the building bottom plate is cast in situ and maintained, flexible waterproof mortar is filled in the lower trapezoid groove of the assembled building bottom plate, then the assembled prefabricated wall plate is hoisted to enable the trapezoid convex teeth and the trapezoid groove to be in butt joint, so that concave-convex tooth grooves are mutually meshed, the assembled building top plate and the assembled prefabricated wall plate also adopt the same connecting structure, and due to the dead weight of the assembled prefabricated wall plate, the flexible waterproof mortar filled in the lower trapezoid groove in advance can be extruded to the surfaces of the floor plates at the two sides of the lower trapezoid groove, so that the flexible waterproof mortar fully fills the horizontal joint between the floor plates and the prefabricated wall plate, the waterproof property of the horizontal joint between the floor plates and the horizontal joint between the prefabricated wall plate and the floor plates in the vertical direction and the shear resistance of the horizontal direction are guaranteed, and meanwhile, the construction efficiency is greatly improved.
Further, the joint comprises a middle cavity and joint openings at two sides, and the lengths of the protruding parts of the upper trapezoid convex teeth and the lower trapezoid convex teeth are smaller than those of the recessed parts of the upper trapezoid groove and the lower trapezoid groove, so that the cavity filled with waterproof mortar is formed.
Further, the width of the cavity is 50mm-80mm.
Further, the width of the seam opening at the two sides is 20mm-30mm.
Further, the waterproof mortar is flexible waterproof mortar.
By adopting the structure, the horizontal joint adopts the concave-convex trapezoid tooth groove type joint, and the concave-convex key trapezoid tooth groove type joint is more common, so that the flexible waterproof mortar is fully contacted with the joint surface, the composite floor slab and the wallboard are integrated, and the waterproof performance is improved. The overall stability is also improved, when the wallboard sits, the wallboard cannot incline due to different thicknesses of flexible waterproof mortar when sitting, and the concave-convex key trapezoid tooth groove joint improves the integrity of the wall body and the laminated floor slab and improves the shearing resistance of the joint. Therefore, the waterproof measures adopted by the patent thoroughly solve the waterproof problem of the external wall panel through comprehensive control, provide reliable waterproof guarantee for the high-efficiency assembled wall panel, and greatly improve the production efficiency and the building quality of the assembled building.
In summary, according to the special construction process of the horizontal seam connecting structure of the prefabricated wall boards and the assembled floor boards, the horizontal seam of the prefabricated wall boards and the floor boards is reliably filled with the flexible waterproof mortar, so that the water seepage and water accumulation phenomena of the outer wall surfaces of the assembled building are effectively improved, the traditional process of the connecting structure of the prefabricated wall boards and the floor boards is optimized, and the method can be widely applied to prefabricated wall board structures and cast-in-situ composite floor board structures.
