Description

Technical Field

[0001] This invention relates to the field of concealed beam floor slab technology, specifically to a concealed beam floor slab structure and construction method that is easy to assemble. Background Technology

[0002] Traditional beam-slab structures are extremely cumbersome due to the outward protrusion of the beams, making the erection of internal scaffolding, formwork installation, and rebar tying extremely complicated. Furthermore, the installation of ventilation and fire protection pipes in the basement ceiling occupies a significant amount of headroom due to the outward protrusion of the beams, greatly reducing space utilization. Flat slabs, on the other hand, offer a flat ceiling, simplifying formwork construction, saving on formwork, and facilitating rebar tying, thus greatly improving construction speed. The flat ceiling also makes it easier to install ventilation and fire protection pipes, resulting in a more open and aesthetically pleasing space. The design of flat slabs optimizes the process, improves progress, and reduces costs while increasing efficiency. Traditional flat slabs require laying concealed beam rebar first, then interlacing and tying the slab rebar, and later, during basement installation, expansion bolts are needed to fix supports on the floor slab, making the process cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a conveniently assembled concealed beam floor slab structure and construction method, which is easy to operate and improves the ease of assembly, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Furthermore, a through groove is provided on the side of the connecting seat, a positioning block is movably sleeved inside the through groove, a positioning hole is provided inside the connecting block, and the positioning block is engaged with the positioning hole.

[0007] Furthermore, both the first and second concealed beam floor slabs include a floor slab base plate, the top surface of which is overlapped with reinforcing bars, the top surface of which is overlapped with curved steel plates, and the top surface of which is provided with a moisture-proof board. The first and second concealed beam floor slabs are integrally cast with concrete, and the bottom surface of the floor slab base plate is provided with reserved screw holes.

[0008] Furthermore, the easily assembled concealed beam floor structure also includes a positioning mechanism, which includes an installation plate. A screw is fixedly connected to the center of the top surface of the installation plate, and the screw is threadedly connected to a pre-drilled screw hole. Arc plates are fixedly connected to both sides of the bottom surface of the installation plate.

[0009] Furthermore, there are two arc plates, and the bottom ends of both arc plates are rotatably connected to a rotating shaft. A fixed arc plate is rotatably connected to the surface of the rotating shaft. There are two fixed arc plates. The bottom end of one fixed arc plate is fixedly connected to a first clamping block, and the bottom end of the other fixed arc plate is fixedly connected to a second clamping block. The second clamping block is internally threaded with a positioning bolt, and one end of the positioning bolt is threaded into the inside of the first clamping block.

[0010] A construction method for a conveniently assembled concealed beam floor slab structure includes the following steps:

[0011] Step 1: Construct the concealed beam floor slab;

[0012] Step 2: Create the relevant holes;

[0013] Step 3: Assemble the concealed beam floor slab;

[0014] Step 4: Install basement pipes.

[0015] Further, step one specifically includes: placing reinforcing bars on the surface of the floor slab substrate, placing the reinforcing bars in two layers, one longitudinal and one transverse, with the reinforcing bars set longitudinally and vertically, then placing curved steel plates on the surface of the reinforcing bars, and finally placing moisture-proof boards on the top surface of the curved steel plates, then fixing the connecting seats and connecting blocks to both sides of the floor slab substrate respectively, and finally using concrete integral casting to form a hidden beam floor slab.

[0016] Furthermore, step two specifically includes: using drilling equipment to open positioning holes on the side of the connecting block and opening through grooves on the side of the connecting seat, the opening through grooves and positioning holes being adapted to the positioning block.

[0017] Furthermore, step three specifically includes: placing the first concealed beam floor slab in a designated position, then placing the connecting block on the side of the second concealed beam floor slab in the connecting seat on the side of the first concealed beam floor slab, inserting the positioning block through the through groove on the side of the connecting seat, and snapping the positioning block into the positioning hole, thereby realizing the rapid assembly between the first concealed beam floor slab and the second concealed beam floor slab.

[0018] Furthermore, step four specifically includes: fixing the mounting plate to the bottom surface of the floor slab base plate by screwing the screw into the reserved screw hole, placing the pipe between two arc plates, using the action of the rotating shaft to rotate the two fixed arc plates to clamp the pipe, and then screwing the positioning bolt in the second clamping block into the inside of the first clamping block, thereby fixing the first clamping block and the second clamping block, which facilitates the quick fixing of the pipe at the bottom of the floor slab and completes the layout of the basement ventilation, air conditioning and fire protection pipes.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention employs the cooperation of a first concealed beam floor slab, a second concealed beam floor slab, a connecting mechanism, a connecting seat, a connecting block, a positioning hole, a positioning block, and a through groove. By placing the connecting block on the side of the second concealed beam floor slab into the connecting seat on the side of the first concealed beam floor slab, the positioning block is inserted through the through groove on the side of the connecting seat and then snapped into the positioning hole. Since the positioning block is rectangular, it can fix the connecting block in the connecting seat, thereby realizing rapid assembly between the first and second concealed beam floor slabs and improving the convenience of assembly.

[0021] 2. This invention employs a combination of floor slab substrate, reinforcing steel bars, curved steel plates, moisture-proof boards, and concrete. Reinforcing steel bars are placed on the surface of the floor slab substrate in two layers, arranged longitudinally and vertically. Curved steel plates are then placed on top of the reinforcing steel bars, and finally, a moisture-proof board is placed on top of the curved steel plates. The concrete is then poured integrally to form a concealed beam floor slab. The reinforcing steel bars increase the strength of the floor slab, the curved steel plates increase its rigidity, and the waterproof membrane used in the moisture-proof board enhances the floor slab's moisture-proof performance.

[0022] 3. This invention employs a combination of pre-drilled screw holes, a positioning mechanism, a mounting plate, a screw rod, an arc plate, a rotating shaft, a fixed arc plate, a first clamping block, a second clamping block, and positioning bolts. By screwing the screw rod into the pre-drilled screw hole, the mounting plate is fixed to the bottom surface of the floor slab. The pipe is placed between the two arc plates, and the two fixed arc plates are clamped by rotating the shaft. Then, the positioning bolt in the second clamping block is screwed into the first clamping block, thereby fixing the first and second clamping blocks. This facilitates the rapid fixing of pipes at the bottom of the floor slab, making it easier to lay out basement ventilation, air conditioning, and fire protection pipes, resulting in a more open and aesthetically pleasing space.
