Description

Assembled reinforced concrete truss floor board

Technical field

The invention relates to the technical field of building materials, in particular to a prefabricated reinforced truss floor slab.

Background technique

The general slab pouring is the detachable assembly of the reinforced concrete truss and the floor slab produced in the factory. The slabs with the reinforced trusses are spliced at the construction site, and the concrete is poured. After the concrete is solidified, the floor slab is removed and reused. This enables factory production, reducing the impact of the environment and weather on the construction period, and the production safety and quality of the truss are guaranteed. However, when the existing floor slabs are spliced at the construction site, the splicing joints are left. When the concrete is poured, due to the weight of the concrete, the splicing seams of the floor slabs are misplaced, which makes the pouring floor uneven.

In order to solve the above problem, the splicing fixing plate is usually installed in a "patching" manner under the splicing seam of the floor slab, and the fixing plate is spaced apart from the floor slabs connected to both sides of the splicing seam for Reduce the misalignment of the joints of the floor panels. The above method has many drawbacks. The installation and disassembly of the fixed plate not only requires a large workload to affect the construction period, but also increases construction safety measures and potential safety hazards, which greatly increases the construction cost.

Summary of the invention

The present invention provides a prefabricated reinforced truss floor slab for the existing assembly floor slab, which has the problem of misalignment of the splicing seam, inconvenient installation and disassembly, etc., and the support member is provided under the condition that the floor slab is assembled and disassembled conveniently. Reduce the misalignment of the seams, so that the floor surface of the casting is flat.

To achieve the above object, the technical solution provided by the present invention is:

The utility model relates to a prefabricated reinforced truss floor slab, which comprises a floor slab, a side of the floor slab is detachably connected with the reinforced truss, and the other side of the floor slab is spaced apart with a support member, the support member is extended Floor Deck. According to the present invention, the support member protrudes from the left side or the right side of the floor panel or the left and right sides simultaneously. When the floor panel is spliced, the support member protrudes to support the adjacent floor panel, so that both sides of the seam are The floor slab is supported by the support member, and the staggered joint displacement phenomenon is reduced or even disappeared; and the support member is removed at the same time as the floor slab is removed, and the additional work generated by disassembling the support member is not increased, so that the floor slab and the support are provided. The parts have a more stable and efficient use.

Further, a part of the support member protrudes from one side of the floor panel, and another part of the support member protrudes from the other side of the floor panel. A part of the support member of the invention protrudes from the left side of the floor support plate, and a part of the support member protrudes to the right side of the floor support plate, so as to avoid providing only one of the two adjacent assembled reinforced concrete truss floor support plates to provide support force to the other, so that the floor support plate is stressed.

Phenomenon is also conducive to mechanization and automated assembly.

Further, a connector is further included, the connector is provided with a card slot, the card slot is engaged with the reinforced truss, and the connecting member and the floor plate are connected by a fastener. According to the invention, the connecting member is convenient for adjusting the connection density, the connecting position and the relative distance of the floor slab and the reinforced truss. The card slot openings of each set of connectors are opposite or snapped into the reinforced truss so that the snaps are not easily detached.

Further, the supporting member is provided with a fixing hole, and the floor receiving plate is provided with a connecting hole, and one end of the fastener is sequentially connected to the connecting member through the fixing hole and the connecting hole. The invention reduces the amount of fasteners used, and also reduces the workload of assembling the support members, the floor slabs and the reinforced trusses, thereby greatly reducing the cost; the support members can be regarded as the gaskets of the floor slabs and the connecting members, and the reduction is reduced. The wear and tear of the floor slabs enhances the support of the support members to the adjacent splicing floor slabs and reduces the possibility of misalignment of the splicing seams.

Further, the support member is provided with a plurality of sets of fixing holes, and the fixing holes are oblong holes or round holes.
