The technology of the concrete laminated floor slab is that the floor slab is divided into two parts along the thickness direction, the bottom part is a prefabricated bottom plate, and the upper part is post-cast with a concrete laminated layer. The prefabricated bottom plate with the bottom steel bars is used as a part of a floor slab, is used as a template of a post-cast concrete superposed layer to bear load in the construction stage, and forms an integral superposed concrete member with the post-cast concrete layer. The concrete composite floor slab is divided into a unidirectional stressed laminated slab and a bidirectional stressed laminated slab according to the specific stressed state. The patchwork can be divided into a separate type seam (i.e. a 'close-spliced' seam in which the bottom plates are not pulled apart) and an integral type seam (i.e. a post-cast concrete strip is arranged between the bottom plates) according to the connection mode. Generally, the unidirectional sheets employ a split seam and the bidirectional sheets employ an integral seam.
The existing assembled type close-splicing overlapped floor slab connection mainly adopts a one-way plate separation type joint technology, the one-way plates in the technology are provided with ribs in the stress rib direction, the ribs cannot be provided in the distribution rib direction, a joint of 5-10mm is reserved between the two one-way plates, and additional steel bars with the same diameter as the distributed steel bars are placed on the surfaces of prefabricated plates to ensure the continuity of the steel bars. The main problems of this connection are as follows:
(1) the seam position of disconnect-type seam appears the crack easily, though does not influence structure safety, but seriously influences the use experience of owner.
(2) Because the production error of the one-way plate or the construction error during the connection between two adjacent one-way plates can cause the height difference between the two one-way plates, the impression effect of the floor slab is seriously influenced, the difficulty of subsequent decoration construction is increased, and the decoration effect is influenced.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem among the prior art, the utility model provides a close amalgamation of assembled floor, the problem of crack and dislocation appear easily at the seam position of having solved the close amalgamation of assembled floor among the prior art.
In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:
the utility model provides a close amalgamation floor of assembled, it includes prefabricated bottom plate layer and the back-pouring superimposed layer that is located prefabricated bottom plate layer top and the connecting reinforcement that lower, upper end were absorbed in respectively prefabricated bottom plate layer and back-pouring superimposed layer, the pre-buried steel sheet that has the surface to be not less than the face of piece together in the bottom of the face of piece together of prefabricated bottom plate layer, prefabricated bottom plate layer has the hollow groove in the below reservation of steel sheet.
Further, the depth of the connecting steel bars sunk into the prefabricated floor slab or the post-cast laminated layer is not less than one-half layer thickness of the corresponding layer.
Furthermore, the connecting steel bars are in sine wave shapes and are symmetrically distributed relative to the top surface of the prefabricated floor layer in the vertical direction.
Furthermore, reinforcing steel bars are distributed in the prefabricated bottom plate layer and the post-cast laminated layer.
Further, the reinforcing steel bars in the prefabricated floor layer are arranged above the steel plate.
Further, the hollow groove is open toward one side of the joint face.
Further, in the direction perpendicular to the abutted seam surface, the width of the hollow groove is not less than half of the width of the steel plate.
Further, in the direction parallel to the joint face, the length of the hollow groove is equal to that of the steel plate and is equal to that of the joint face in the direction.
The utility model has the advantages that: the assembled close-spliced and overlapped floor slab in the scheme has the advantages of simple structure, stable connection, capability of reducing the construction difficulty and improvement on the construction efficiency.
By pre-burying the steel plates at the abutted seam surfaces, during on-site construction, the prefabricated composite floor slabs are directly abutted together, and the adjacent composite floor slabs are fixed after being abutted by welding the steel plates without reserving a post-cast strip, so that the work of formwork support and erection support of the on-site post-cast strip is reduced, and the on-site construction efficiency is improved; and during the concatenation, the smooth steel sheet in surface is changeed in the alignment, and the efficiency of construction is higher, is difficult to produce the difference in height, and welded steel sheet makes the intensity of coincide floor connection better, is difficult to produce defects such as crack, has improved construction quality, makes its application more extensive.
