Description

Technical Field

[0001] The present application relates to the technical field of building climbing frames, and in particular to a T-shaped screw reinforcement device for a climbing frame passing through a floor slab. Background Art

[0002] At the construction site of the main structure of a high-rise building, a circle of climbing frame protection or scaffolding protection needs to be built around the main structure and used as a working platform. As a new type of construction frame protection during the construction of the main structure, the climbing frame needs to be attached to the main structure in multiple layers during use. When erecting, inclined rods are often used to reinforce the climbing frame protection to avoid the situation where the pins are pulled out, so as to better ensure construction safety.

[0003] At present, when using inclined rods to connect the climbing frame to the main structure, embedded screws are usually used as part of the reinforcement device. However, after the subsequent construction is completed, the protruding parts of the embedded screws need to be cut off, and the embedded screws originally buried in the main structure are cast together with the concrete structure, resulting in the embedded screws being unable to be recycled, and the embedded screws will cause corrosion to the concrete structure. Utility Model Content

[0004] In order to improve the problem that the embedded screws cannot be reused and are easy to corrode the concrete structure, the present application provides a T-shaped screw reinforcement device for a climbing frame passing through the floor slab.

[0005] The present application provides a T-shaped screw reinforcement device for a climbing frame passing through a floor slab, which adopts the following technical solution:

[0006] A T-shaped screw reinforcement device for a climbing frame passing through a floor slab, comprising a protective sleeve, a T-shaped screw, a nut and a connecting structure. The protective sleeve is pre-buried in a concrete floor slab and passes through the concrete floor slab. The T-shaped screw passes through the protective sleeve. The T-shaped screw is locked and fixed to the concrete floor slab by the nut. The connecting structure is fixed above the concrete floor slab by the T-shaped screw. The connecting structure is used to be connected to a diagonal rod.

[0007] By adopting the above technical solution, during the use of the climbing frame through the floor T-shaped screw reinforcement device, the protective sleeve is first embedded in the concrete floor, and after the concrete is formed, the T-shaped screw is then passed through the protective sleeve and the connecting structure, and the T-shaped screw is locked and fixed with a nut, so that the connecting structure can be fixed above the concrete floor through the T-shaped screw. One end of the inclined rod is connected to the connecting structure, and the other end is connected to the climbing frame body, so that the climbing frame body is connected to the concrete floor through the inclined rod. After the reinforcement device is used, the nut is unscrewed and the T-shaped screw is taken out to realize the recycling of the T-shaped screw. The protective sleeve can prevent the T-shaped screw from directly contacting the concrete floor, slow down the rusting rate of the T-shaped screw, and reduce the corrosion of the concrete structure.

[0008] Preferably, the T-shaped screw includes a threaded rod and a fixed plate fixedly connected, the threaded rod passes through the protective sleeve, the fixed plate abuts against the lower surface of the concrete floor, and one end of the threaded rod away from the fixed plate passes through the upper surface of the concrete floor and is threadedly connected to a nut, and the connecting structure is fixed to the upper surface of the concrete floor by the cooperation of the nut and the threaded rod.

[0009] By adopting the above technical solution, the fixing plate of the T-shaped screw is located below the concrete floor, the threaded rod passes through the protective sleeve and the connection structure and extends from above the concrete floor, the threaded rod is fixed with a nut, and the connection structure is fixed above the concrete floor by the T-shaped screw in coordination with the limit of the fixing plate below the concrete floor. In addition, the user can lock and fix the threaded rod above the concrete floor, which improves the convenience of the user.

[0010] Preferably, the outer wall of the threaded rod abuts against the inner wall of the protective sleeve.

[0011] By adopting the above technical solution, the threaded rod can be stably placed in the protective sleeve, thereby improving the stability of the T-shaped screw in fixing the connecting device on the concrete floor.

[0012] Preferably, the connection structure includes a fixedly connected reinforcement base and a fixing member, the reinforcement base abuts against the upper surface of the concrete floor, the end of the threaded rod away from the fixing plate passes through the reinforcement base, the nut acts on the top of the reinforcement base to fix the reinforcement base to the concrete floor, and the fixing member is connected to the diagonal rod.

[0013] By adopting the above technical solution, the reinforced base increases the contact area between the end of the nut close to the fixing plate and the upper surface of the concrete floor, making the connection of the T-shaped screw to the upper end of the concrete floor more stable. At the same time, the fixing piece is fixedly connected to the reinforced base, and the fixing piece is connected to the diagonal tie rod, so that the diagonal tie rod can be connected to the reinforced base through the fixing piece.

[0014] Preferably, the fixing member includes two ear plates, a pin and a locking buckle, the two ear plates are arranged in parallel and spaced apart, and the ear plates are fixedly connected to the reinforcement base; the pin passes through the two ear plates, and the pin is fixed to the ear plates by the locking buckle; the diagonal rod is located between the two ear plates, and the diagonal rod passes through the pin.

The diagonal tie rod rotates around the pin shaft and can be adjusted to a suitable angle to connect with the climbing frame body, thereby improving the flexibility and adjustability of the connection between the diagonal tie rod and the climbing frame body.

[0016] Preferably, both ends of the protective sleeve are flush with the upper and lower surfaces of the concrete floor slab respectively.

[0017] By adopting the above technical solution, the protective sleeve completely separates the threaded rod from the concrete floor, minimizes the contact area between the threaded rod and the concrete, better slows down the rusting speed of the threaded rod, and reduces the risk of concrete corrosion.

[0018] Preferably, the protective sleeve is a PVC sleeve.

[0019] By adopting the above technical solution, PVC has good corrosion resistance and can resist the erosion of various chemical substances. It will not corrode even if buried in concrete for a long time, and has high chemical stability. PVC does not react with threaded rods or concrete. Therefore, using PVC as the material of the protective sleeve can better slow down the corrosion rate of threaded rods and reduce the risk of concrete corrosion, making the concrete floor more stable and safe.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The T-shaped screw can be disassembled from the concrete floor slab to achieve the recycling of the T-shaped screw; the protective sleeve prevents the threaded rod from directly contacting the concrete during use, which can slow down the corrosion rate of the threaded rod, extend the service life of the T-shaped screw, and reduce the corrosion of the concrete structure;

[0022] 2. The diagonal tie rod is connected to the fixing part through a pin shaft. This connection method allows the diagonal tie rod to be adjusted to a suitable angle, thereby improving the flexibility and adjustability of the connection between the diagonal tie rod and the climbing frame.

[0023] 3. By limiting the material and size of the protective sleeve, the contact between the T-screw and the concrete is further limited, which further slows down the corrosion rate of the threaded rod and the concrete structure, further prolongs the service life of the T-screw, and enhances the safety and stability of the concrete floor.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0030] An embodiment of the present application discloses a T-shaped screw reinforcement device for a climbing frame passing through a floor slab.

[0032] The reinforcement device includes a protective sleeve 5, a T-shaped screw 1, a nut 6 and a connecting structure 2. The protective sleeve 5 is pre-buried in the concrete floor 3. The T-shaped screw 1 passes through the protective sleeve 5 and is locked and fixed to the concrete floor 3 by the nut 6; the connecting structure 2 is fixed above the concrete floor 3 by the T-shaped screw 1, and the connecting structure 2 is used to connect with the diagonal rod 4.

[0033] Reference Figure 2 and Figure 3 Furthermore, the protective sleeve 5 is provided with a through inner cavity, and the protective sleeve 5 is vertically arranged and penetrates the concrete floor 3. The two ends of the protective sleeve 5 are respectively flush with the upper and lower surfaces of the concrete floor 3, so that the concrete floor 3 forms a sleeve hole surrounded by the protective sleeve 5, and the sleeve hole is used to sleeve the T-shaped screw 1. The protective sleeve 5 can prevent the T-shaped screw 1 from directly contacting the concrete floor 3, slow down the corrosion rate of the T-shaped screw 1, and reduce the corrosion of the concrete structure.

[0034] Furthermore, the T-shaped screw 1 includes a threaded rod 11 and a fixing plate 12, and the threaded rod 11 and the fixing plate 12 are welded and connected. The length of the threaded rod 11 is greater than the length of the protective sleeve 5, and the diameter of the threaded rod 11 is smaller than the diameter of the protective sleeve 5. The threaded rod 11 can pass through the sleeve hole to penetrate into the protective sleeve 5, and at the same time, the outer wall of the threaded rod 11 abuts against the inner wall of the protective sleeve 5, so that the threaded rod 11 can be stably placed in the protective sleeve 5. The diameter of the fixing plate 12 is greater than the diameter of the sleeve hole, so that the fixing plate 12 cannot enter the sleeve hole.

The reinforcement base 21 is provided with a first connection hole 211 matching the diameter of the threaded rod 11, and the end of the threaded rod 11 away from the fixing plate 12 can pass through the first connection hole 211, and the nut 6 acts on the top of the reinforcement base 21 to fix the reinforcement base on the upper surface of the concrete floor 3. The reinforcement base 21 is used to fix the fixing member 22, and the reinforcement base 21 improves the locking effect of the nut 6, so that the connection between the end of the T-shaped screw 1 away from the fixing plate 12 and the top of the concrete floor 3 is more stable.

[0037] When in use, the threaded rod 11 of the T-shaped screw 1 is passed through the protective sleeve 5 and then through the first connecting hole 211 of the reinforcement base 21, and then the threaded rod 11 is locked with the nut 6, so that the reinforcement base 21 is fixed to the concrete floor 3 through the T-shaped screw 1.

[0038] Reference Figure 2 and Figure 4 The fixing member 22 includes two ear plates 221, a pin 222 and a locking buckle 223. The two ear plates 221 are arranged in parallel and spaced apart, and the ear plates 221 are welded and fixed to the reinforcement base 21. The two ear plates 221 are provided with second connection holes 224, and the two second connection holes 224 are coaxially arranged; the pin 222 penetrates the inclined brace rod 4 and the second connection holes 224 of the two ear plates 221 at the same time, and is fixed to the ear plates 221 by the locking buckle 223. When in use, by rotating the inclined brace rod 4, the inclined brace rod 4 can be connected to the climbing frame body at a suitable angle, so as to achieve the effect of connecting the climbing frame body to the concrete floor slab 3.

[0039] In this embodiment, the concrete floor 3 is 120 mm thick; the protective sleeve 5 is a PVC sleeve, the PVC sleeve is Ø22 mm and 120 mm long; the threaded rod 11 of the T-shaped screw is Ø20 mm and 220 mm long, the fixing plate 12 is a rectangular steel plate of 100×100×10 mm; the nut 6 is M20 type; the reinforcement base 21 is a rectangular steel plate of 100×100×10 mm; the ear plate 221 is a trapezoidal ear plate, and the long side of the trapezoidal ear plate is welded to the reinforcement base 21; the diagonal tie rod 4 is Ø32 mm.

[0040] The implementation principle of the embodiment of the present application is as follows: the PVC sleeve is pre-buried in the concrete floor 3 in advance, and when the concrete is formed, the threaded rod 11 of the T-shaped screw 1 is placed in the PVC sleeve to effectively avoid direct contact between the T-shaped screw 1 and the concrete floor 3; the threaded rod 11 passes through the sleeve hole from the PVC sleeve and passes through the first connection hole 211 of the reinforcement base 21, and the nut 6 is sleeved on the threaded rod 11 and tightened, so that the reinforcement base 21 is abutted and fixed on the top of the concrete floor 3.
