Description

Technical Field

[0001] The utility model relates to the technical field of cap beam hoop construction, in particular to a self-assembling cap beam bottom formwork and an auxiliary removal device for edge protection. Background Art

[0002] The dismantling of the traditional cap beam bottom formwork and edge protection is generally carried out by setting an upper beam and a lower beam connected by a hand winch at the top and bottom of the cap beam. The platform is lowered to the ground by the hand winch to complete the dismantling. The hand winch is generally connected to the beam through a support frame, and the support frame is welded to the beam. The welding points are difficult to inspect and potential problems are difficult to detect in time. The overall flexibility of the structure after welding is low, and it is not convenient to adjust or move, which limits the flexibility of use. Moreover, its own installation requires the full assistance of a crane, and the hoisting is difficult and the installation is relatively cumbersome. Utility Model Content

[0003] The utility model provides a self-assembling cap beam bottom formwork and an auxiliary removal device for edge protection, which can overcome certain defects of the prior art.

[0004] According to the utility model, a self-assembly type cap beam bottom formwork and edge protection auxiliary dismantling device includes a plurality of upper beams and lower beams respectively arranged above and below the cap beam, a hand winch is provided between the upper beams and the lower beams, a first connecting part is provided between the hand winch and the upper beam, a second connecting part is provided between the hand winch and the lower beam, the first connecting part and the second connecting part respectively include a first steel wire rope and a second steel wire rope arranged vertically, and hooks are respectively provided between the lower end of the first steel wire rope and the upper end of the second steel wire rope and the hand winch.

[0005] By adopting the utility model, after the strength of the cap beam reaches the standard and the side formwork of the cap beam is removed, when removing the bottom formwork of the cap beam and the edge protection, the upper beam is first hoisted to the top of the cap beam, and the two hand hoists are fixed to the two ends of the upper beam through the first connection part. The construction personnel then pull the hand hoist to lower the hand hoist hook to the ground, and then fix the two hooks to the two ends of the lower beam respectively through the second connection part. The construction personnel then pull the hand hoist to raise the hook and the lower beam to the top of the clamp, and repeat this step until all the lower beams are raised to the top of the clamp. The installation construction personnel then removes the original load-bearing clamp, and the lower beam becomes the new load-bearing part. The construction personnel then pull the hand hoist at the same time to slowly lower the bottom formwork of the cap beam and the edge protection to the ground to complete the dismantling.

[0006] The installation of the demolition device only requires a crane to lift the upper beam to the top of the cap beam. The subsequent installation can be completed by the operation of its own structure. After the installation is completed, the removal of the bottom formwork and edge protection no longer requires the assistance of a crane, which greatly reduces the use of cranes, increases its own flexibility and reduces costs.

[0007] Preferably, the first connecting portion further comprises a first connecting block slidable on the upper crossbeam, and the upper end of the first steel wire rope is nested in the first connecting block and the upper crossbeam.

[0008] Through the utility model, the first connection part has a simple structure and is relatively easy to install, which reduces the pre-preparation and installation time; its structure is visualized, and compared with the welded support frame, it can be intuitively observed whether the first steel wire rope and other structures are damaged, so as to take precautions in advance and prevent accidents; the first steel wire rope itself has a higher strength. Compared with the support frame welded on the upper beam, the first steel wire rope is directly arranged on the upper beam, and the connection strength depends on the strength of the first steel wire rope itself, so the first steel wire rope has higher strength than the welded support frame; and by adjusting the length of the first steel wire rope, the height of the hand winch can be conveniently adjusted to adapt to different working conditions.

[0009] Preferably, the second connecting portion further comprises a second connecting block slidable on the lower cross beam, and a shackle is provided between the lower end of the second steel wire rope and the second connecting block.

[0010] Through the utility model, the design of the shackle between the second steel wire rope and the second connecting block facilitates the installation of the lower beam. After the upper beam is installed, the hook of the hand hoist and the second steel wire rope are lowered to the ground through the hand hoist, and the lower beam is quickly connected and fixed to the lower end of the second steel wire rope through the shackle. Then the hand hoist is tightened to pull the lower beam to the predetermined position, completing the overall assembly of the dismantling device. The self-assembling structural design makes it possible for the installation of the lower beam to be achieved through its own structure, and only the upper beam needs to be hoisted, which greatly reduces the difficulty of hoisting and the use of the crane.

[0011] Preferably, the first connecting block is configured to be a U-shaped block with a recessed middle portion and an upward opening.

[0012] Through the utility model, the first connecting block is configured to be a U-shaped block with a recessed middle portion and an opening facing upward. The recessed design in the middle portion facilitates precise positioning, ensuring that the first steel wire rope and the first connecting block are more accurately docked, reducing installation errors, and preventing the first steel wire rope from sliding and falling off during lifting. The upward opening design enables the first steel wire rope to be easily hung in the first connecting block during installation, thereby simplifying the installation process and improving installation efficiency.

[0013] Preferably, the second connecting block is configured to be in the shape of a cuboid, and a semicircular hanging lug is provided above the second connecting block.

[0014] Through the utility model, the second connecting block with a rectangular shape is easy to process during the manufacturing process, which can reduce production costs; the semicircular design of the lifting ear enables it to be smoothly connected to the shackle during the lifting process, reducing friction during lifting and increasing the stability of its own structure.

[0015] Preferably, the upper beam and the lower beam are each provided with an adjustment slot passing through themselves, and threaded connecting columns passing through the adjustment slots at both ends of the upper beam and the lower beam are provided below the first connecting block and the second connecting block, and nuts are provided on the connecting columns.

[0016] Through the utility model, through the design of the adjustment groove, the threaded connecting column can slide in the adjustment groove. Without changing the overall structure, the load-bearing width of the upper and lower beams can be adjusted according to the different widths of the cap beams, thereby adapting to different installation requirements and compensating for errors in the manufacturing and installation process; through the design of the threaded connecting column and the nut, the threaded connecting column can quickly pass through the adjustment groove and be fixed by the nut, which speeds up the installation speed and improves work efficiency; after the nut is fixed, it can ensure that the connection between the connecting column and the upper and lower beams is more firm, thereby enhancing the bearing capacity of the entire structure; when maintenance or replacement of parts is required, the parts can be quickly adjusted or replaced by loosening the nut, which is convenient for repair and maintenance.

[0017] Preferably, the upper and lower crossbeams are made of double-pieced I-beams.

[0018] Through the utility model, the I-beam has high bending strength and compressive strength. The application of double-spliced I-beams further improves the bearing capacity of the beam, which is suitable for structures that bear larger loads. Moreover, its structure is stable, and the cross-sectional shape of the I-beam gives it good bending and torsional resistance. The use of double-spliced I-beams provides a better structure and reduces deformation under load. Moreover, as a hot-rolled steel, the cost of I-beams is relatively low. The use of double-spliced I-beams can give full play to the performance of the material, save materials, and reduce the cost of the overall structure.

[0019] Preferably, a plurality of circular holes are provided on the edge protection for the first steel wire rope, the second steel wire rope and the hand hoist to pass through.

[0020] Through the utility model, the circular holes opened on the edge protection can make the first steel wire rope, the second steel wire rope and the hand hoist as close to the side of the cap beam as possible, reduce the force arm of the upper beam and the lower beam, and under certain load and cross-sectional conditions, greatly increase the bending resistance of the upper beam and the lower beam; the provision of the circular holes can avoid direct contact and interference of the first steel wire rope, the second steel wire rope and the hand hoist with the edge protection, thereby protecting the integrity and stability of the protection structure.

[0030] like Figure 1-7 As shown, this embodiment provides a self-assembling cap beam bottom formwork and edge protection auxiliary dismantling device, which includes a plurality of upper beams 110 and lower beams 120 respectively arranged above and below the cap beam 150, a hand winch 170 is provided between the upper beam 110 and the lower beam 120, a first connecting part 130 is provided between the hand winch 170 and the upper beam 110, and a second connecting part 140 is provided between the hand winch 170 and the lower beam 120, the first connecting part 130 and the second connecting part 140 respectively include a first steel wire rope 510 and a second steel wire rope 520 arranged vertically, and a hook 530 is respectively provided between the lower end of the first steel wire rope 510 and the upper end of the second steel wire rope 520 and the hand winch 170.

[0031] Through this embodiment, after the strength of the cap beam 150 reaches the standard and the side formwork of the cap beam 150 is removed, when the bottom formwork and the edge protection 420 of the cap beam 150 are removed, the upper beam 110 is first hoisted to the top of the cap beam 150, and the two hand winches 170 are fixed to the two ends of the upper beam 110 through the first connecting part 130. Then, the construction personnel pull the hand winch 170 to lower the hook 530 of the hand winch 170 to the ground 310, and then connect the two hooks 530 to the lower beam through the second connecting part 140. The two ends of 120 are fixed respectively, and the construction personnel then pull the hand hoist 170 to raise the hook 530 and the lower beam 120 to the top of the clamp 160, and repeat this step until all the lower beams 120 are raised to the top of the clamp 160. The installation construction personnel then remove the original load-bearing clamp 160, and the lower beam 120 becomes the new load-bearing part. The construction personnel then pull the hand hoist 170 at the same time to slowly lower the bottom formwork of the cap beam 150 and the edge protection 420 to the ground 310 to complete the dismantling.

[0032] The installation of the dismantling device only requires a crane to lift the upper crossbeam 110 to the top of the cap beam 150. The subsequent installation can be completed by the operation of its own structure. After the installation is completed, the dismantling of the bottom formwork and the edge protection 420 no longer requires the assistance of a crane, which greatly reduces the use of cranes, increases its own flexibility, and reduces costs.

[0033] In this embodiment, the first connecting portion 130 further includes a first connecting block 131 that can slide on the upper beam 110 , and the upper end of the first steel wire rope 510 is nested in the first connecting block 131 and the upper beam 110 .

Compared with the support frame welded on the upper beam 110, the first steel wire rope 510 is directly arranged on the upper beam 110, and the connection strength depends on the strength of the first steel wire rope 510 itself, so the first steel wire rope 510 has higher strength than the welded support frame; and by adjusting the length of the first steel wire rope 510, the height of the hand winch 170 can be conveniently adjusted to adapt to different working conditions.

[0035] In this embodiment, the second connecting portion 140 further includes a second connecting block 141 slidable on the lower cross beam 120 , and a shackle 210 is provided between the lower end of the second steel wire rope 520 and the second connecting block 141 .

[0036] Through this embodiment, the design of the shackle 210 between the second steel wire rope 520 and the second connecting block 141 facilitates the installation of the lower beam 120. After the upper beam 110 is installed, the hook 530 of the hand hoist 170 and the second steel wire rope 520 are lowered to the ground 310 through the hand hoist 170, and the lower beam 120 is quickly connected and fixed to the lower end of the second steel wire rope 520 through the shackle 210. Then, the hand hoist 170 is tightened to pull the lower beam 120 to the predetermined position, completing the overall assembly of the demolition device. The self-assembling structural design allows the installation of the lower beam 120 to be achieved through its own structure, and only the upper beam 110 needs to be hoisted, which greatly reduces the difficulty of hoisting and the use of the crane.

[0037] In this embodiment, the first connection block 131 is configured to be a U-shaped block with a recessed middle portion and an upward opening.

[0038] Through this embodiment, the first connecting block 131 is configured to be recessed in the middle into a U-shaped block with an opening facing upward. The recessed design in the middle facilitates precise positioning, ensuring that the first steel wire rope 510 is more accurately docked with the first connecting block 131, reducing installation errors, and preventing the first steel wire rope 510 from sliding and falling off during hoisting. The upward opening design enables the first steel wire rope 510 to be easily hung in the first connecting block 131 during installation, thereby simplifying the installation process and improving installation efficiency.

[0039] In this embodiment, the second connecting block 141 is configured to be in a rectangular parallelepiped shape, and a semicircular hanging ear 720 is provided above the second connecting block 141 .

[0040] Through this embodiment, the rectangular second connecting block 141 is easy to process during the manufacturing process, which can reduce production costs; the semicircular design of the lifting ear 720 enables it to be smoothly connected to the shackle 210 during the lifting process, reducing friction during lifting and increasing the stability of its own structure.

[0042] Through this embodiment, through the design of the adjustment groove 710, the threaded connecting column 610 can slide in the adjustment groove 710. Without changing the overall structure, the load-bearing width of the upper and lower beams 120 can be adjusted according to the different widths of the cap beam 150, so as to adapt to different installation requirements and compensate for errors in the manufacturing and installation process; through the design of the threaded connecting column 610 and the nut 620, the threaded connecting column 610 can quickly pass through the adjustment groove 710 and be fixed by the nut 620, which speeds up the installation speed and improves work efficiency; after the nut 620 is fixed, it can ensure that the connection between the connecting column 610 and the upper and lower beams 120 is more firm, thereby enhancing the bearing capacity of the entire structure; when maintenance or replacement of parts is required, the parts can be quickly adjusted or replaced by loosening the nut 620, which is convenient for repair and maintenance.

The application of double-spliced I-beams further improves the bearing capacity of the beam, which is suitable for structures that bear larger loads. Moreover, its structure is stable, and the cross-sectional shape of the I-beam gives it good bending and torsional resistance.

The use of double-spliced I-beams can give full play to the performance of the material, save materials, and reduce the cost of the overall structure.

[0045] In this embodiment, a plurality of circular holes 410 are opened on the edge protection 420 for the first steel wire rope 510 , the second steel wire rope 520 and the hand hoist 170 to pass through.
