Description

Assembled architecture prefabricated panel horizontal joint mud jacking Alveolus type waterproof connecting structure
Technical field
The invention belongs to construction engineering technical fields, more particularly to a kind of assembled architecture prefabricated panel horizontal joint pressure Slurry processes Alveolus type waterproof connecting structure.
Background technique
Prefabricated assembled concrete structure refer to the various components of structure include precast shear wall, it is precast beam, prefabricated post, pre- Floor processed, prefabricated panel etc. are standardized production in engineering, then each prefabricated components are bolted at the construction field (site), Structure made of welded connecting or cast-in-place connection installation.Each prefabricated components industrialized production of prefabricated concrete structure, has Save that labour, construction speed is fast, is advantageously implemented building energy conservation, is convenient for industrialized production and the advantages that mechanized construction, fits Answer the developing direction of China's building industrialization.But there are a large amount of splicing seams for fabricated construction, in wallboard and laminated floor slab water Splicing seams leakage is easy to happen at carvel joint, while the being not easily repaired property of composite thermo-insulating wall board considerably increases assembled wallboard infiltration Leak the difficulty administered.Therefore assembled architecture waterproof key is the sealing waterproof of prefabricated panel and the horizontal splicing seams of laminated floor slab.
The piece of prefabricated wallboard and laminated floor slab be horizontal joint, common water proof structure be by laminated floor slab with An anti-bank construction is arranged in wallboard stitching portion, and certain thickness flexible water mortar is laid on the anti-bank and connects the two, should Method cannot be guaranteed the flatness of mortar and may cause wallboard in the inclination of vertical direction, and mortar can not be spelled full of entire The globality stitched and prefabricated panel is caused to connect with laminated floor slab is not strong, and can not be effectively prevented the infiltration of rainwater, waterproof effect Fruit is unobvious, easily generates ponding in piece junction, and the manpower expended in work progress is larger.
Summary of the invention
The present invention solves the deficiencies in the prior art and provides that a kind of structure is simple, installation is convenient, extends component Service life improves the assembled architecture prefabricated panel horizontal joint mud jacking Alveolus type waterproof connecting structure of safety.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of assembled architecture prefabricated panel horizontal joint mud jacking Alveolus type waterproof connecting structure, including it is prefabricated Wallboard and the Assembled Building bottom plate and Assembled Building top plate being connected with prefabricated wallboard, the Assembled Building bottom plate is even The position for connecing assembled prefabricated panel is prefabricated with descending stair connected in star, and the Assembled Building top plate is in the formula prefabricated panel that is linked and packed Position is prefabricated with upper trapezoid double wedge, is prefabricated on prefabricated wallboard joint face corresponding with Assembled Building bottom plate and institute State the corresponding lower trapezoid double wedge of descending stair connected in star, it is pre- on prefabricated wallboard joint face corresponding with Assembled Building top plate It is formed with upper trapezoid groove corresponding with the upper trapezoid double wedge, is preset with a certain amount of Waterproof sand in the upper and lower trapezoidal groove Slurry, so that after the Assembled Building top plate is fitted on prefabricated wallboard from the top down by prefabricated wallboard, institute It states between upper trapezoid double wedge and upper trapezoid groove, be respectively formed one layer between the lower trapezoid double wedge and descending stair connected in star and be covered with seam Waterproof mortar course.The present invention bottom of the building plate it is cast-in-place, maintenance after the completion of, filled in the descending stair connected in star of Assembled Building bottom plate soft Property waterproof mortar, then lifting prefabricated wallboard docks its trapezoidal double wedge and trapezoidal groove, so that concave-convex tooth socket is mutual Occlusion, Assembled Building top plate and prefabricated wallboard also use same connection structure, due to prefabricated wallboard from Heavy, the flexible water mortar filled in advance in descending stair connected in star can be pressed out to the two sides slab surfaces of descending stair connected in star, in turn So that flexible water mortar is sufficient filling with the horizontal joint between floor and prefabricated panel, floor and wallboard horizontal joint ensure that Waterproofness and vertical direction prefabricated panel and floor between globality, the shear resistance in direction of improving the standard, while Construction efficiency is greatly improved.
Further, the seam includes central cavity and two sides seam openings, and the upper and lower trapezoidal double wedge protrudes part Length is respectively less than the upper and lower trapezoidal groove and falls in the cavity that part forms perfusion waterproof mortar.
Further, the width of the cavity is 50mm-80mm.
Further, seam openings width in two sides is 20mm-30mm.
Further, the waterproof mortar is flexible water mortar.
Since using the above structure, horizontal joint of the invention is using concave-convex stepped tooth slot type seam, this bumps Key stepped tooth slot type relatively leads to common horizontal joint, so that making overlapping building with seam face contact more than flexible water mortar is abundant Plate and wallboard improve waterproof performance at being integral.Overall stability is also improved, when wallboard is sat and starched, it will not be because of seat The thickness of flexible water mortar is different when slurry and generation inclination, this bumps key stepped tooth slot type seam improve wall and fold The shear resistance of the seam crossing is also improved while closing the globality of floor.Therefore, the waterproof measure that this patent uses, through comprehensive Prevention and treatment is closed, thoroughly solves the waterproof problem of Side fascia, reliable waterproof is provided for efficient assembled wallboard and guarantees, also with regard to pole The production efficiency and construction quality of assembled architecture are improved greatly.
In conclusion special construction of the present invention according to prefabricated wallboard and assembled floor horizontal joint connection structure Process is reliably filled with the horizontal joint of prefabricated panel and floor with flexible water mortar, effectively improves assembled architecture The infiltration of wall face and seeping phenomenon optimize the prefabricated wallboard of tradition and floor connection structure technique, can be widely applied In prefabricated wall panels structure and cast-in-place laminated floor slab structure.
