Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of composite floor slabs, and particularly relates to a composite slab for prefabricated buildings. Background Art
[0002] A composite floor slab is an assembled integral floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. The composite floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer, and is suitable for high-rise buildings and large-span buildings with high requirements for overall stiffness. The following problems exist in the prior art:
[0003] Because the existing building composite floor slabs are manufactured by the method of pouring cement mixed with steel bars, only the steel bars exposed around the composite slab can be used for assembly and combination, resulting in the problem that the exposed steel bars are very easy to injure workers during construction, and it is not conducive to assembly, with high danger. Moreover, in the existing composite slabs, the fixedly arranged truss steel bars are continuous. After the composite slab is hoisted, the truss steel bars no longer play any role, resulting in a great waste of resources, and the continuous truss steel bars will also affect the later pipeline installation, and it is not conducive to the flexible and effective layout of pipelines. Summary of the Utility Model
[0004] The utility model provides a composite slab for prefabricated buildings to solve the problems raised in the above background art.
[0005] To solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A composite slab for prefabricated buildings includes a composite floor slab. An assembly clamping plate one is fixedly installed on the front outer wall of the composite floor slab, and an assembly clamping plate two is fixedly installed on the left outer wall of the composite floor slab. A clamping plate one positioning hole is opened on the outer wall of the assembly clamping plate one, and a clamping plate two positioning hole is opened on the outer wall of the assembly clamping plate two. An assembly slot two is opened on the right inner wall of the composite floor slab, and a pouring hole two is penetrated and opened on the top inner wall of the assembly slot two. An assembly slot one is opened on the rear inner wall of the composite floor slab, and a pouring hole one is penetrated and opened on the top inner wall of the assembly slot one.
[0007] The further improvement of the technical solution of the utility model lies in that: the size of the assembly clamping plate one is the same as the inner wall size of the assembly slot one, and the inner wall size of the clamping plate one positioning hole is the same as the inner wall size of the pouring hole one.
[0008] The further improvement of the technical solution of the utility model lies in that: the size of the assembly clamping plate two is the same as the inner wall size of the assembly slot two, and the inner wall size of the clamping plate two positioning hole is the same as the inner wall size of the pouring hole two.
[0009] By adopting the above technical solution, through the mutual cooperation among the positioning holes of the first clamping plate, the positioning holes of the second clamping plate, the first pouring hole, and the second pouring hole in this solution, the assembled composite floor slab can be directly poured with cement for fixation.
[0010] A further improvement of the technical solution of the present utility model lies in that: laminated floor slab steel bars are fixedly installed in the inner cavities on both the upper and lower sides of the laminated floor slab.
[0011] By adopting the above technical solution, through the laminated floor slab steel bars in this solution, the fixation of the first lifting ring and the second lifting ring is made more firm.
[0012] A further improvement of the technical solution of the present utility model lies in that: the first lifting rings are fixedly installed on both sides above the front side of the laminated floor slab, the outer wall of the bottom end of the first lifting ring is fixedly connected to the outer wall of one end of the front side of the laminated floor slab steel bars, and the first lifting ring slots are provided on the outer walls of the left and right ends above the rear side of the laminated floor slab.
[0013] A further improvement of the technical solution of the present utility model lies in that: the second lifting rings are fixedly installed on both sides below the rear side of the laminated floor slab, the outer wall of the bottom end of the second lifting ring is fixedly connected to the outer wall of one end of the right side of the laminated floor slab steel bars, and the second lifting ring slots are provided on the outer walls of the left and right ends below the front side of the laminated floor slab.
[0014] By adopting the above technical solution, through the mutual cooperation among the first lifting ring, the second lifting ring, the first lifting ring slot, and the second lifting ring slot in this solution, the laminated floor slab can be lifted by the double first lifting rings and the double second lifting rings on the front and rear sides, which is convenient for handling, and when assembling, the first lifting ring is snapped into the first lifting ring slot and the second lifting ring is snapped into the second lifting ring slot without affecting the assembly.
[0015] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:
[0016] 1. The utility model provides a composite slab for prefabricated buildings. By using the cooperation of assembly slot 1, pouring hole 1, assembly slot 2, pouring hole 2, assembly clamping plate 1, clamping plate 1 positioning hole, assembly clamping plate 2, and clamping plate 2 positioning hole, when assembling the composite floor slab, one assembly clamping plate 1 of one composite floor slab is clamped into the assembly slot 1 of another composite floor slab, and the pouring hole 1 is aligned with the clamping plate 1 positioning hole. Then, the assembly clamping plate 2 is aligned with the assembly slot 2 of another composite floor slab, and the pouring hole 2 is aligned with the clamping plate 2 positioning hole. Then, cement is poured into the clamping plate 1 positioning hole and the clamping plate 2 positioning hole through the pouring hole 1 and the pouring hole 2 respectively, so that the assembly of the composite slab is completed. This solves the problem that the existing building composite floor slabs are manufactured by pouring a mixture of cement and steel bars, and can only be assembled and combined by relying on the steel bars exposed around the composite slab, resulting in the exposed steel bars being very easy to injure workers during construction, and being not conducive to assembly, with a relatively high risk. It achieves the effect of making the assembly between the composite floor slabs safer and more efficient by using the method of internal steel bars.
[0017] 2. The utility model provides a composite slab for prefabricated buildings. By using the cooperation of lifting ring 1, lifting ring slot 1, lifting ring 2, lifting ring slot 2, and composite floor slab steel bars, when the composite floor slab needs to be lifted, only the lifting ropes need to pass through the inner walls of the two lifting rings 1 and the two lifting rings 2 respectively. Moreover, both the lifting ring 1 and the lifting ring 2 are fixedly connected to the composite floor slab steel bars built into the composite floor slab, so it is more firm. And when the composite floor slab is assembled, the lifting ring 1 will be clamped into the lifting ring slot 1, and the lifting ring 2 will be clamped into the lifting ring slot 2, which does not affect the assembly. This solves the problem that in the existing composite slabs, the fixedly arranged truss steel bars are continuous. After the composite slab is hoisted, the truss steel bars no longer play any role, resulting in a great waste of resources, and the continuous truss steel bars will also affect the later pipeline installation, being not conducive to the flexible and effective layout of pipelines. It achieves the effect of keeping both the upper and lower surfaces of the composite floor slab flat by installing four lifting rings on the side of the composite floor slab, saving costs and facilitating the later pipeline installation.

[0028] AsFigures 1-4 As shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, laminated floor slabs 1 are fixedly installed in the inner cavities on both the upper and lower sides of the laminated floor slab 1.
