Description

Technical Field

[0001] This invention relates to the field of prefabricated hollow core slab technology, and in particular to a prefabricated steel mesh slab and its implementation method. Background Technology

[0002] Steel mesh hollow components are a new type of hollow box structure used in new floor slab structural systems. They are suitable for public buildings such as schools with large column grids, large spans, large spaces, and multiple floors. They offer flexible application space and have significantly improved economic and technical indicators compared to other floor slab systems. Steel mesh hollow components have outstanding advantages in energy saving, consumption reduction, and load-bearing capacity. They also have the absolute advantages of low self-weight and simple construction operation.

[0003] In current steel mesh construction, if the steel mesh is directly processed into boxes in the factory and then transported to the construction site, the steel mesh will occupy a large amount of transport space, reducing the quantity transported and thus reducing transport efficiency. If the steel mesh panels and sheets are transported to the construction site separately and manually welded by operators, this process is time-consuming and labor-intensive, and requires operators to have certain technical skills. This reduces the installation and construction efficiency of the steel mesh and may even affect the construction progress. Therefore, this application proposes a prefabricated steel mesh and its implementation method. Summary of the Invention

[0004] The purpose of this invention is to address the problem that steel mesh is inconvenient to transport and assemble in the prior art, and to propose a prefabricated steel mesh and its implementation method.

[0005] In a first aspect, the present invention proposes an assembled steel mesh grille, comprising a top plate, a first steel mesh fixedly connected inside the top plate, a crossbar fixedly connected at the center of the first steel mesh, a side plate rotatably connected to one side of the first steel mesh via a three-segment rotating shaft, a second steel mesh fixedly connected at the center of the side plate, a fixing plate provided on one side of the side plate, a third steel mesh fixedly connected inside the fixing plate, two sets of the side plate and the second steel mesh being provided, the two sets of side plates being connected to each other via a three-segment rotating shaft, a bottom plate being connected to the lower set of side plates via a three-segment rotating shaft, a fourth steel mesh fixedly connected to the inner wall of the bottom plate, and a fixing component provided at the bottom of the top plate for fixing the positions of the top plate, side plate, fixing plate and bottom plate.

[0006] Optionally, the fixing component includes a top frame disposed on the outer wall of the top plate. The bottom of the top frame is attached to the top of the side plate and the fixing plate. The top frame is square in shape. A support rod is fixedly connected to the bottom of the top frame. A bottom frame is fixedly connected to the bottom of the support rod. Two sets of square grooves are provided on one side of both the side plate and the fixing plate. Threaded grooves are provided on the inner wall of the square grooves. Square plates are fixedly connected to both sides of the support rods. The square plates are inserted into the inner wall of the square grooves. A round hole is provided on one side of the square plate. A screw is inserted into the round hole and installed in the threaded groove through the round hole.

[0007] Optionally, corner protectors are fixed at the corners of the top frame, and multiple sets of corner protectors are provided, which are respectively distributed at the corners of the top frame and the bottom frame.

[0008] Optionally, a support rod is rotatably connected to the top of the base plate. The support rod is U-shaped, and a stop block is fixed to the bottom of the crossbar. The top of the support rod is located inside the stop block.

[0009] Optionally, a closing plate is rotatably connected to the top of one side of the stop block, a mating block is fixed to the bottom of one side of the stop block, and a ramp is provided on one side of the mating block.

[0010] Optionally, the bottom of the base plate is provided with a storage groove, and a rotating rod is rotatably connected to the inner wall of the storage groove. A hook is fixed to one side of the rotating rod.

[0011] Optionally, a side groove is provided on one side of the bottom of the storage slot, and a long plate is slidably provided on the inner wall of the side groove. The long plate is located at the bottom of the hook, and a pull block is fixed to the bottom of the long plate.

[0012] Optionally, a fastener is inserted between the two sets of side plates, and a positioning block is fixed to one side of the fastener, with one end of the positioning block being inclined.

[0013] Optionally, the surfaces of the first, second, third, and fourth steel meshes are all processed using a galvanizing process.

[0014] Secondly, the present invention provides a method for implementing a prefabricated steel mesh cutout, applicable to the aforementioned prefabricated steel mesh cutout, the method comprising the following steps:

[0015] S1. The first steel mesh, the second steel mesh, the third steel mesh and the fourth steel mesh are galvanized. After the galvanizing is completed, the first steel mesh, the second steel mesh, the third steel mesh and the fourth steel mesh can be welded to the center of the top plate, the side plate, the fixed plate and the bottom plate respectively, which facilitates the subsequent assembly of the steel mesh.

[0016] S2. Weld the two sets of side plates together using a set of three-section pivots to allow the two sets of side plates to flip. Weld the upper set of side plates to the bottom of the top plate using a second set of three-section pivots, ensuring that it can flip. Weld the lower set of side plates to the top of the bottom plate using a third set of three-section pivots, and perform anti-corrosion treatment on the welded parts.

[0017] S3. After welding, push the two sets of side plates to one side. A three-section pivot at the center of the two sets of side plates can cause them to fold. After the two sets of side plates are folded, the distance between the top plate and the bottom plate can be shortened, thereby reducing the space occupied by the steel mesh and facilitating the transportation of the steel mesh.

[0018] S4. After transporting the steel mesh to the construction site, the top plate can be lifted upwards. When the top plate is lifted upwards, it will cause the two sets of side plates to flip and keep the two sets of side plates perpendicular to the top plate. Then, the fixing plate is placed between the top plate and the bottom plate, and the positions of the top plate, side plates, fixing plate and bottom plate are fixed by the fixing components to facilitate the assembly and fixing of the steel mesh.

[0019] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0020] This invention, by setting two sets of side plates and three sets of three-segment rotating shafts, allows the two sets of side plates to fold towards the center. The folded two sets of side plates are located between the top plate and the bottom plate, which facilitates the transportation of steel mesh components and saves transportation space, allowing for the transport of more steel mesh components. When the steel mesh needs to be assembled, the top plate can be pulled upwards, allowing the two sets of side plates to flip over via the three sets of three-segment rotating shafts until the two sets of side plates are perpendicular to the top plate. Then, a fixing plate is placed between the top plate and the bottom plate, and the positions of the top plate, bottom plate, side plates, and fixing plate are fixed by fixing components, which facilitates the assembly of the steel mesh and solves the problem of the inconvenience of transporting and assembling steel mesh components.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 9As shown, the present invention proposes an assembled steel mesh perforation, comprising a top plate 1, wherein a first steel mesh 2 is fixedly connected to the interior of the top plate 1, and a crossbar 3 is fixedly connected to the center of the first steel mesh 2. During the production of the steel mesh perforation, the first steel mesh 2 is welded to the interior of the top plate 1, and the crossbar 3 is welded to the center of the first steel mesh 2. A side plate 4 is rotatably connected to one side of the first steel mesh 2 via a three-section rotating shaft 6. A second steel mesh 5 is fixedly connected to the center of the side plate 4 and welded to the interior of the side plate 4. A fixing plate 7 is provided on one side of the side plate 4, and a third steel mesh 8 is fixedly connected inside the fixing plate 7. Two sets of side plates 4 and second steel mesh 5 are provided, and the two sets of side plates 4 are connected... The two sets of side plates 4 are connected by a three-section pivot 6. The bottom set of side plates 4 is connected to the bottom plate 17 by the three-section pivot 6. By welding a three-section pivot 6 between the two sets of side plates 4 and installing the two sets of side plates 4 on one side of the top plate 1 and the bottom plate 17 respectively by the other two sets of three-section pivot 6, the two sets of side plates 4 can be folded towards the center. The folded two sets of side plates 4 will be located between the top plate 1 and the bottom plate 17, which facilitates the transportation of steel mesh accessories and saves transportation space, which is conducive to transporting more sets of steel mesh. A fourth steel mesh 18 is fixed to the inner wall of the bottom plate 17. The fourth steel mesh 18 can be installed on the inner wall of the bottom plate 17 by welding.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, a fixing assembly is provided at the bottom of the top plate 1. This fixing assembly is used to fix the positions of the top plate 1, side plate 4, fixing plate 7, and bottom plate 17. The fixing assembly includes a top frame 11, which is disposed on the outer wall of the top plate 1. The bottom of the top frame 11 is attached to the top of the side plate 4 and the fixing plate 7. The top frame 11 is square in shape. A support rod 14 is fixedly connected to the bottom of the top frame 11, and a bottom frame 16 is fixedly connected to the bottom of the support rod 14. When it is necessary to fix the positions of the top plate 1, bottom plate 17, side plate 4, and fixing plate 7, the top frame 11 can be fitted onto the outer wall of the top plate 1, and the bottom frame 16 can be fitted onto the outer wall of the bottom plate 17. Then, the support rod 14 is welded between the top frame 11 and the bottom frame 16. One side of the side plate 4 and the fixing plate 7... Each support rod 14 has two sets of square grooves 9, and the inner wall of the square grooves 9 has a threaded groove 10. Square plates 12 are fixed to both sides of the support rod 14. The square plates 12 are inserted into the inner wall of the square grooves 9. At this time, the square plates 12 on both sides of the support rod 14 will be inserted into the square grooves 9 on the side plate 4 and the fixing plate 7. The side plate 4 and the fixing plate 7 can be positioned by the cooperation of the square plates 12 and the square grooves 9. A round hole is opened on one side of the square plate 12. A screw 13 is inserted into the round hole. The screw 13 is installed in the threaded groove 10 through the round hole and screwed into the round hole on the square plate 12. The screw 13 is gradually screwed into the threaded groove 10. By tightening the screw 13, the side of the side plate 4 and the fixing plate 7 is locked onto the support rod 14, which facilitates the stable assembly of the steel mesh.

[0034] like Figure 2 As shown, corner protectors 15 are fixed to the corners of the top frame 11. Multiple sets of corner protectors 15 are provided and distributed at the corners of the top frame 11 and the bottom frame 16. By providing corner protectors 15 at the corners of the top frame 11 and the bottom frame 16, the corner protectors 15 can protect the corners of the bottom frame 16 and the top frame 11 after the steel mesh is assembled, preventing damage to the corners of the bottom frame 16 and the top frame 11 caused by bumps.

[0035] like Figure 4 , Figure 5 and Figure 6As shown, a support rod 19 is rotatably connected to the top of the base plate 17. The support rod 19 is U-shaped. When the two sets of side plates 4 are perpendicular to the top plate 1, the support rod 19 can be flipped to stand upright. A stop block 20 is fixed to the bottom of the crossbar 3. The top of the support rod 19 is located inside the stop block 20. A closing plate 21 is rotatably connected to the top of one side of the stop block 20. A mating block is fixed to the bottom of one side of the stop block 20. A ramp is provided on one side of the mating block. When the top of the support rod 19 passes through the mating block on one side of the stop block 20... The support rod 19 is guided into the stop block 20 by the ramp on one side of the mating block. When the top of the support rod 19 enters the stop block 20, it pushes the closing plate 21 to one side. After the support rod 19 enters the stop block 20, the closing plate 21 will flip downwards due to gravity and press against one side of the mating block. This prevents the support rod 19 from moving out of the stop block 20 and prevents the support rod 19 from continuing to flip to the other side. This keeps the support rod 19 at the bottom of the crossbar 3, which facilitates the support between the top plate 1 and the bottom plate 17.

[0036] like Figure 6 and Figure 7 As shown, the bottom of the base plate 17 has a storage groove 22. A rotating rod 23 is rotatably connected to the inner wall of the storage groove 22. A hook 24 is fixedly connected to one side of the rotating rod 23. A side groove 25 is formed on one side of the bottom of the storage groove 22. A long plate 26 is slidably arranged on the inner wall of the side groove 25. The long plate 26 is set at the bottom of the hook 24. When the hook 24 is not needed, the bottom of the storage groove 22 can be closed by setting the long plate 26 to prevent the hook 24 from being exposed. A pull block 27 is fixedly connected to the bottom of the long plate 26. When it is necessary to flip it over... When hook 24 is in use, pull block 27 can be pulled to open the long plate 26 to one side, allowing hook 24 to flip. After hook 24 flips, pull block 27 can be pulled again to push the long plate 26 to one side until the long plate 26 is against one side of hook 24, keeping hook 24 exposed. After multiple sets of hooks 24 are exposed, the steel mesh can be placed in the designated position of the rebar cage. The multiple sets of exposed hooks 24 can make hook 24 hang on the rebar cage, thus preventing the steel mesh from floating with the concrete during subsequent concrete pouring.

[0037] like Figure 3 and Figure 8As shown, a fastener 28 is inserted between the two sets of side plates 4. When the two sets of side plates 4 are kept perpendicular to the top plate 1, the fastener 28 can be inserted at the connection between the two sets of side plates 4. A positioning block 29 is fixed to one side of the fastener 28. One end of the positioning block 29 is inclined. The positioning block 29 on one side of the fastener 28 will first contact the side plate 4. The inclination of one side of the positioning block 29 will allow the positioning block 29 to pass through the side plate 4. After the fastener 28 is fastened between the two sets of side plates 4, the shape of one side of the fastener 28 can be used to keep the fastener 28 installed on the side plate 4 and prevent the fastener 28 from falling off the side plate 4. The installation of the fastener 28 can keep the position of the two sets of side plates 4 fixed.

[0038] like Figure 1 and Figure 4 As shown, the surfaces of the first steel mesh 2, the second steel mesh 5, the third steel mesh 8, and the fourth steel mesh 18 are all processed by galvanizing. By processing the surfaces of the first steel mesh 2, the second steel mesh 5, the third steel mesh 8, and the fourth steel mesh 18 by galvanizing, the corrosion resistance and overall service life of the steel mesh can be greatly improved, thus giving it an overwhelming advantage over ordinary steel mesh in most application scenarios.

[0039] A method for implementing a prefabricated steel mesh cutout, applied to the aforementioned prefabricated steel mesh cutout, includes the following steps:

[0040] S1. The first steel mesh 2, the second steel mesh 5, the third steel mesh 8 and the fourth steel mesh 18 are galvanized. After the galvanizing is completed, the first steel mesh 2, the second steel mesh 5, the third steel mesh 8 and the fourth steel mesh 18 can be welded to the center of the top plate 1, the side plate 4, the fixing plate 7 and the bottom plate 17 respectively, which facilitates the subsequent assembly of the steel mesh.

[0041] S2. Weld the two sets of side plates 4 together through a set of three-section rotating shafts 6 so that the two sets of side plates 4 can be flipped. Weld the upper set of side plates 4 to the bottom of the top plate 1 through the second set of three-section rotating shafts 6, and ensure that it can be flipped. Weld the lower set of side plates 4 to the top of the bottom plate 17 through the third set of three-section rotating shafts 6, and perform anti-corrosion treatment on the welded parts.

[0042] S3. After welding, push the two sets of side plates 4 to one side. A set of three-section rotating shafts 6 at the center of the two sets of side plates 4 can cause them to fold. After the two sets of side plates 4 are folded, the distance between the top plate 1 and the bottom plate 17 can be shortened, thereby reducing the space occupied by the steel mesh and facilitating the transportation of the steel mesh.

[0043] S4. After the steel mesh is transported to the construction site, the top plate 1 can be lifted upwards. When the top plate 1 is lifted upwards, it will cause the two sets of side plates 4 to flip and keep the two sets of side plates 4 perpendicular to the top plate 1. Then, the fixing plate 7 is placed between the top plate 1 and the bottom plate 17, and the positions of the top plate 1, side plates 4, fixing plate 7 and bottom plate 17 are fixed by the fixing components, so as to facilitate the assembly and fixing of the steel mesh.

[0044] Working Principle: To solve the problem of inconvenient transportation and assembly of steel mesh cutters, during the production of the steel mesh cutter, the first steel mesh 2 is welded to the inside of the top plate 1, and a crossbar 3 is welded at the center of the first steel mesh 2. Then, the second steel mesh 5 is welded to the side plate 4, and simultaneously, the fourth steel mesh 18 is welded to the inner wall of the bottom plate 17. A set of three-section rotating shafts 6 is then welded between the two sets of side plates 4, and the two sets of side plates 4 are respectively installed on one side of the top plate 1 and the bottom plate 17 via the other two sets of three-section rotating shafts 6. This allows the two sets of side plates 4 to fold towards the center, and the folded two sets of side plates 4 will be located between the top plate 1 and the bottom plate 17, thus facilitating the transportation of the steel mesh cutter components and saving transportation space, which is beneficial for transporting more sets of steel mesh cutters. When the steel mesh cutter needs to be assembled, the top plate 1 can be pulled upwards. The movement allows the two sets of side plates 4 to be flipped through three sets of three-section rotating shafts 6 until the two sets of side plates 4 are perpendicular to the top plate 1. At this time, the support rod 19 can be flipped to make the support rod 19 stand up. When the support rod 19 is flipped up, the support rod 19 is guided into the interior of the stop block 20 by the ramp on one side of the mating block. When the top of the support rod 19 enters the stop block 20, it will push the closing plate 21 to one side. After the support rod 19 enters the stop block 20, the closing plate 21 will flip down with gravity and abut against one side of the mating block, which can prevent the support rod 19 from moving out of the interior of the stop block 20, so that the support rod 19 is located at the bottom of the crossbar 3, which facilitates the support between the top plate 1 and the bottom plate 17 through the support rod 19. Then the fixing plate 7 is placed between the top plate 1 and the bottom plate 17.

[0045] When it is necessary to fix the positions of the top plate 1, bottom plate 17, side plate 4 and fixing plate 7, the top frame 11 can be fitted onto the outer wall of the top plate 1 and the bottom frame 16 can be fitted onto the outer wall of the bottom plate 17. Then, the support rod 14 is welded between the top frame 11 and the bottom frame 16. At this time, the square plates 12 set on both sides of the support rod 14 will be inserted into the square grooves 9 on the side plate 4 and the fixing plate 7. The side plate 4 and the fixing plate 7 can be positioned by the cooperation of the square plates 12 and the square grooves 9. The screws 13 are screwed into the round holes on the square plates 12, so that the screws 13 are gradually screwed into the threaded grooves 10. By tightening the screws 13, the sides of the side plate 4 and the fixing plate 7 are locked onto the support rod 14, which facilitates the stable assembly of the steel mesh. After the steel mesh is assembled, the corner protectors 15 are used to protect the corners of the bottom frame 16 and the top frame 11 to prevent damage to the corners of the bottom frame 16 and the top frame 11 caused by bumps.

[0046] When hook 24 is not needed, the bottom of the storage slot 22 can be closed by setting the long plate 26 to prevent hook 24 from being exposed. When hook 24 needs to be flipped, the pull block 27 can be pulled to open the long plate 26 to one side and flip hook 24 downward. Since hook 24 is fixed to the rotating rod 23, the rotation of the rotating rod 23 can cause hook 24 to rotate out of the storage slot 22. After hook 24 is flipped out, the pull block 27 can be pulled again to push the long plate 26 in the opposite direction until the long plate 26 abuts against one side of hook 24, so that hook 24 remains exposed. After multiple sets of hooks 24 are exposed, the steel mesh can be placed in the designated position of the rebar cage. The multiple sets of exposed hooks 24 can make hook 24 hang on the rebar cage, so that the steel mesh is prevented from floating with the concrete during subsequent concrete pouring.

[0047] The above specific embodiments are merely several optional embodiments of the present invention.

After the two sets of side plates (4) are folded, the distance between the top plate (1) and the bottom plate (17) can be shortened, thereby reducing the space occupied by the steel mesh and facilitating the transportation of the steel mesh. S4. After the steel mesh is transported to the construction site, the top plate (1) can be lifted upwards. When the top plate (1) is lifted upwards, it will cause the two sets of side plates (4) to flip and keep the two sets of side plates (4) perpendicular to the top plate (1). Then, the fixing plate (7) is placed between the top plate (1) and the bottom plate (17), and the positions of the top plate (1), side plates (4), fixing plate (7) and bottom plate (17) are fixed by fixing components, so as to facilitate the assembly and fixing of the steel mesh.
