Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a core formwork floor decking structure and a construction method. Background Art

[0002] In the professional field of construction engineering, the core formwork is a very critical internal structural element. It is presented in a specific geometric shape, embedded in the floor system, and cooperates with the surrounding materials to form a core formwork floor deck structure. This innovative structure gives full play to the advantages of the core formwork, and in modern construction projects such as high-rise office buildings and large commercial complexes that have strict requirements on spatial layout and bearing performance, it demonstrates its unique charm and becomes a frontier exploration direction to promote the advancement of construction technology.

[0003] The traditional floor slab structure is mainly composed of steel trusses, corrugated steel plates and concrete. As the core load-bearing component, the steel trusses bear the vertical load from above the floor slab and effectively transfer it to the supporting structure to ensure the stability of the overall structure; the corrugated steel plates provide a temporary operating platform for the construction phase, facilitating the walking of personnel and the stacking of materials; on the other hand, after the concrete is poured, they work together with the concrete to enhance the bending resistance of the floor slab; the concrete is filled on the corrugated steel plates, and after solidification, it forms a solid bearing surface to bear the floor load.

[0004] The above-mentioned existing technologies have deficiencies and shortcomings. When a building is put into long-term use, once the floor decking is partially damaged, it is urgent to replace the problematic panels. Due to the lack of convenient disassembly function, the demolition operation has to use professional cutting tools, which is undoubtedly a difficult and high-risk operation. It not only requires the operator to be skilled and experienced, but also greatly increases the probability of safety accidents. During the operation, the floor decking and surrounding related structures are very susceptible to irreversible physical damage, such as edge damage caused by cutting, structural deformation caused by forced disassembly, etc., which greatly reduces the integrity and stability of the structure. For this reason, a core mold floor decking structure is proposed to solve the above problems. Summary of the invention

[0005] In order to make up for the above shortcomings, the present invention provides a core formwork floor decking structure, aiming to improve the problem of cumbersome construction of a single core formwork hollow floor in the prior art.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a core formwork floor deck structure, comprising a bearing plate, a large core formwork body and a small core formwork body, the top of the bearing plate is evenly threaded with a plurality of connectors, the interior of the connector is provided with a detachable component for easy disassembly, the interior of the connector is fixedly connected with two connecting steel bars, the top of the bearing plate is fixedly connected with a 310 mm high truss, and the interior of the 310 mm high truss is fixedly connected to the outside of the plurality of connecting steel bars;

[0007] Moreover, the detachable component includes a connecting piece, the front end of the connecting piece is fixedly connected to a front end plug-in plate, the front end plug-in plate is provided with a front end pin hole, the middle of the connecting piece is fixedly connected to a middle end plug-in plate, the middle end plug-in plate is provided with a middle end pin hole, the rear end of the connecting piece is fixedly connected to a terminal plug-in plate, the terminal plug-in plate is provided with a terminal pin hole, and the interior of the connecting piece is slidably connected to a pin;

[0008] Moreover, two placement grooves are provided in the middle of the connecting piece, and two reinforcing convex strips are fixedly connected to the front and rear sides of the middle end insert plate;

[0009] Moreover, the interior of the large core mold body is fixedly connected with the upper part of the large core mold, the interior of the large core mold body is fixedly connected with the lower part of the large core mold, the interior of the small core mold body is fixedly connected with the upper part of the small core mold, the bottom of the small core mold body is fixedly connected with the lower part of the small core mold, the rear side of the upper part of the large core mold is fixedly connected with a plastic hook, and the rear end of the plastic hook is fixedly connected to the front side of the upper part of the small core mold;

[0010] Moreover, a plurality of support tubes are fixedly connected to the bottom of the bearing plate, and a plurality of threaded rods are fixedly connected to the bottom of the bearing plate;

[0011] Moreover, the exteriors of the multiple connecting steel bars are fixedly connected to the upper and lower sides of the large core mold body, the exteriors of the multiple connecting steel bars are fixedly connected to the upper and lower sides of the small core mold body, and the multiple large core mold bodies and the multiple small core mold bodies are connected by multiple connecting steel bars.

[0012] The present invention has the following beneficial effects:

[0013] In the present invention, the construction of a single core mold hollow floor is complicated and does not meet the requirements of assembly. The core mold steel truss floor deck combines the core mold and the steel truss together, which is convenient to construct and does not require on-site formwork. It belongs to an assembled building and uses large and small core molds that are suitable for 300mm thick floors and 250mm to 600mm thick floors. It can be widely used in large-span public buildings such as schools. BRIEF DESCRIPTION OF THE DRAWINGS
