Technical Field

The utility model belongs to the technical field of the construction, more specifically say, in particular to anti concrete superimposed sheet mosaic structure that splits.

Background

The laminated slab is an assembled integral floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. The composite floor slab has good integrity, the upper and lower surfaces of the slab are smooth, the decoration of a finish coat is convenient, and the composite floor slab is suitable for high-rise buildings and large-bay buildings with higher requirement on the integral rigidity. The prestressed main reinforcement of the thin plate is the main reinforcement of the laminated floor slab, and the upper concrete cast-in-place layer is only provided with negative moment reinforcement and constructional reinforcement. The prestressed thin plate is used as a bottom die of a cast-in-place concrete layer, and a template does not need to be supported by the cast-in-place layer.

The composite floor slab has the advantages of integrity, high rigidity, good crack resistance, no increase of reinforcing steel bar consumption, template saving and the like of a cast-in-place floor slab. Because the cast-in-place floor slab does not need to be provided with a formwork, and the large precast concrete partition boards can be simultaneously hoisted in the structural construction stage, the cast-in-place floor slab can be inserted into decoration engineering in advance, and the construction period of the whole engineering is shortened.

Through retrieval, for example, patent with the patent number of CN209277364U discloses a concrete laminated slab splicing structure, which comprises a laminated slab body, positioning steel bars, positioning steel bar holes, laminated slab connecting steel bars and stirrups, wherein the positioning steel bars are respectively arranged at two ends of one side wall of the laminated slab body, one ends of the positioning steel bars extend into the laminated slab body, the positioning steel bar holes are arranged at two ends of the other side wall of the laminated slab body, and the laminated slab bodies are fixedly connected through the positioning steel bars penetrating into the positioning steel bar holes; the bottom end of the laminated slab connecting steel bar is arranged in the laminated slab body, and the top end of the laminated slab connecting steel bar vertically extends out of the upper surface of the laminated slab body; the stirrup encircles and sets up in four superimposed sheet connecting reinforcement top outsides, and realizes fixed connection with superimposed sheet connecting reinforcement. The utility model discloses superimposed sheet changes into the connected mode that superimposed sheet connected reinforcement cooperation stirrup fastening, has reduced the shear stress of concatenation department, and structural strength is high, and the construction is nimble, requires the precision low to superimposed sheet production, and production simple process, low in production cost, anti shear stress ability is strong, and the wholeness is strong.

For another example, patent No. CN210049465U discloses a concrete superimposed sheet concatenation seam additional strengthening, it includes the concrete superimposed sheet, concrete superimposed sheet upper end fixedly connected with steel bar truss, the reinforcement steel sheet has been buried underground along fore-and-aft both sides to the concrete superimposed sheet, the reinforcement steel sheet of concrete superimposed preset plate both sides sets up crisscross from top to bottom, wherein one side reinforcement steel sheet flushes with the concrete superimposed sheet and sets up, fixedly connected with connecting steel plate on the reinforcement steel sheet, fixedly connected with backup pad on the connecting steel plate, the backup pad sets up with reinforcing steel sheet parallel to each other, the one end fixedly connected with plugboard of concrete superimposed preset plate is kept away from to the reinforcement steel sheet, plugboard and joint groove match the setting. The utility model discloses in the installation concrete coincide prefabricated plate, the reinforcement steel sheet of adjacent concrete coincide prefabricated plate lateral wall can superpose together, and the joint groove can match each other with the plugboard and peg graft together, makes the concrete interact reinforced connection of reinforcing steel sheet and post-cast.

Based on the above, in the existing building construction process, the laminated slabs are usually directly laid above the bottom plate and then are fixed through concrete pouring, and due to the fact that the fixing degree of the adjacent laminated slabs is low, the later-stage laminated slabs can move to cause cracks to appear in concrete, and the progress of the engineering is delayed.
