Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a composite slab strip reinforcement device. Background Technology

[0002] In construction engineering, the reinforcement and installation of composite slab strips is a crucial step in ensuring the stability and safety of building structures. Traditional processing of composite slab strips involves multiple complex construction steps, such as accurately measuring and locating the rebar positions, cutting, bending, and binding the rebars, and installing threaded rods to fix the rebar positions and ensure structural stability. Workers need to be proficient in various skills, and each step requires careful operation to avoid errors, increasing the complexity and time cost of construction. Furthermore, the price of materials such as rebars and threaded rods is relatively high, and they are not reusable, which not only increases costs but also causes environmental pollution due to the accumulation of construction waste.

[0003] To address these issues, we designed a composite plate and strip reinforcement device. Utility Model Content

[0004] The purpose of this utility model is to provide a composite plate and strip reinforcement device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a composite plate and strip reinforcement device, including a plate and strip body, a top reinforcement unit installed on the top of the plate and strip body, the top reinforcement unit including a transition support member disposed on one side of the plate and strip body, an embedded part pre-embedded on the side of the plate and strip body near the transition support member, the embedded part being located below the transition support member, a top support block being provided on the top of the transition support member, and a reinforcement component installed at the bottom of the plate and strip body, the reinforcement component including a through thread screw, the through thread screw being threadedly connected to the embedded part.

[0006] Furthermore, the bottom of the strip body is provided with a steel back rib, which is located above the through thread screw, and the through thread screw passes through the steel back rib and the top support block.

[0007] Furthermore, a nut is provided on the top of the top support block, and the nut engages with a through thread screw.

[0008] Furthermore, the transition support is a conical structure, with its small end in contact with the embedded part and its large end connected to the top support block. The transition support is made of aluminum alloy.

[0009] Furthermore, a gasket is provided between the strip body and the steel back rib, the gasket is fixedly connected to the top of the steel back rib, and the threaded rod is threadedly connected to the gasket.

[0010] Furthermore, the top support block is made of alloy steel.

[0011] Furthermore, the gasket is made of rubber.

[0012] Furthermore, the steel back rib is formed by cross-welding of transverse and longitudinal bars, and the steel back rib forms a grid-shaped frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting threaded rods to tightly connect with embedded parts, the steel back ribs are fixed to the bottom of the strip body. This structure allows the entire reinforcement system to fit tightly against the strip body, reducing gaps and preventing grout leakage during concrete pouring. The conical structure of the transition support can evenly distribute the upper load to the strip body. The connections between the threaded rods, top support blocks, transition support, and other structures are easy to disassemble and reuse, reducing material waste, making it more environmentally friendly, and lowering material costs during construction. During construction, the components can be assembled or disassembled in sequence, improving installation and disassembly efficiency and reducing construction time.

[0015] 2. The threaded rod can be easily pre-tightened or loosened by rotating the nut. The threaded connection between the threaded rod and the embedded part, as well as the reinforcement effect of the steel back rib, prevents the formwork from deforming due to uneven stress during concrete pouring. The threaded connection between the threaded rod and the embedded part, the stable cooperation of the top support block and the transition support, ensure the safety of construction personnel and reduce the risk of safety accidents.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a composite plate and strip reinforcement device, including a plate and strip body 1, a top reinforcement unit 4 installed on the top of the plate and strip body 1, the top reinforcement unit 4 including a transition support 41 disposed on one side of the plate and strip body 1, the transition support 41 plays the role of dispersing and transmitting load, and transmitting the upper load to the plate and strip body 1 in a more uniform manner, a pre-embedded part 2 is pre-embedded on the side of the plate and strip body 1 near the transition support 41, the pre-embedded part 2 is located below the transition support 41, a top support block 42 is provided on the top of the transition support 41, the transition support 41 has a conical structure, its small end contacts the pre-embedded part 2, and its large end is connected to the top support block 42, the transition support 41 is made of aluminum alloy, the top support block 42 is made of alloy steel, which has high strength and toughness and can better bear the load, a reinforcement component 3 is installed at the bottom of the plate and strip body 1, the reinforcement component 3 includes a threaded screw 33, the threaded screw 33 is threadedly connected to the pre-embedded part 2.

[0023] In specific implementation, when the strip body 1 is cast, the embedded part 2 is fixed in the designed position so that its top is flush with or slightly lower than the strip surface. After the strip body 1 is formed, the small end of the transition support 41 is aligned with the embedded part 2 and placed on the top of the strip body 1. Then, the top support block 42 is put on the large end of the transition support 41 and the center hole is aligned with the threaded rod 33. Then, the threaded rod 33 is inserted vertically downward from the center hole of the top support block 42 and the bottom is screwed into the internal thread of the embedded part 2. After that, the preload is applied by rotating the nut 43 at the top so that the threaded rod 33 pulls the top support block 42, the transition support 41, the embedded part 2 and the strip body 1 to form an integral force system. The position of each component is checked to ensure that the transition support 41 is in complete contact with the strip body 1 without loosening.

[0024] See Figures 2-3As shown, the bottom of the strip body 1 is provided with a steel back rib 31. The steel back rib 31 is formed by cross-welding of transverse and longitudinal rods. The steel back rib 31 has a grid-shaped frame, which enhances the overall structural stability. The steel back rib 31 is located above the threaded rod 33. The threaded rod 33 passes through the steel back rib 31 and the top support block 42. A gasket 32 ​​is provided between the strip body 1 and the steel back rib 31. The gasket 32 ​​is made of rubber and is fixedly connected to the top of the steel back rib 31. The threaded rod 33 is threadedly connected to the gasket 32. The top support block 42 is provided with a nut 43. The nut 43 cooperates with the threaded rod 33. In use, first install the steel back rib 31 at the bottom of the strip body 1, fix the gasket 32 ​​to the top of the steel back rib 31, so that the threaded rod 33 passes through the steel back rib 31 and the gasket 32 ​​in sequence. Finally, install the nut 43 on the top of the top support block 42 and cooperate with the threaded rod 33 to tighten it.

[0025] Working principle:

[0026] Before construction begins, the embedded part 2 needs to be fixed in the design position during the pouring of the strip body 1, so that its top is flush with or slightly lower than the surface of the strip. After the strip body 1 is formed, the small end of the transition support 41 is aligned with the embedded part 2 and placed on the top of the strip body 1. Then, the top support block 42 is fitted onto the large end of the transition support 41, so that the center hole is aligned with the threaded rod 33. Then, the threaded rod 33 is inserted vertically downward from the center hole of the top support block 42 and the bottom is screwed into the embedded part 2. By rotating the nut 43 at the top, a pre-tightening force is applied, so that the threaded rod 33 connects the top support block 42, the transition support 41, the embedded part 2 and the strip body 1 into an integral force-bearing system. At the same time, the position of each component is checked to ensure that the transition support 41 is in complete contact with the strip body 1 and is not loose.

[0027] Finally, install the steel back rib 31 and related components. Install the steel back rib 31 at the bottom of the strip body 1, fix the gasket 32 ​​to the top of the steel back rib 31, and let the threaded screw 33 pass through the steel back rib 31 and the gasket 32 ​​in sequence. Finally, install the nut 43 on the top of the top support block 42 and tighten it in conjunction with the threaded screw 33.
