Description

Technical Field

[0001] This utility model relates to the field of template reinforcement, and in particular to a template reinforcement device that does not require welding. Background Technology

[0002] Currently, when sealing ultra-wide, irregularly shaped, and large-volume concrete formwork, the most common reinforcement method is single-sided welding of tie rods to the main reinforcing bars, with a lap length of 500mm. This allows the reinforcing bars to be pulled against the formwork through the tie rods, thus achieving formwork reinforcement. However, this construction method has the following drawbacks:

[0003] 1. Single-sided welding of the tie rod to the main reinforcement bar poses a significant risk to the main reinforcement bar. It easily causes a quenched structure in the heat-affected zone of the weld between the main reinforcement bar and the tie rod, resulting in localized hardening of the steel reinforcement and a marked reduction in plasticity. Therefore, when the tie rod is spot-welded to the main reinforcement bar, the spot weld will fracture prematurely under stress, preventing the steel reinforcement from fully utilizing its ductility. Spot welding of the tie rod to the main reinforcement bar also causes necking of the steel reinforcement at the weld joint. When the main reinforcement bar fractures under stress, its elongation will decrease significantly. Furthermore, it can cause micro-cracks at the weld joint, which affect the stress on the steel reinforcement, leading to stress concentration and plastic deformation, ultimately resulting in brittle fracture of the steel reinforcement.

[0004] 2. When welding the tie rod to the main rib, many welding positions are limited by space, making operation inconvenient, resulting in poor welding quality and low work efficiency;

[0005] 3. At the welding point, a 500mm lap welding is required with the main reinforcing bar, resulting in a significant waste of tie rod material;

[0006] 4. Welding operations require the use of electric welding machines, which poses electrical and fire safety hazards. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a welding-free template reinforcement device.

[0008] The technical solution includes a tie rod fixedly connected to the reinforcing cage. The tie rod is shaped and has threads on its outer surface. The closed part of the tie rod is provided with two U-shaped clips. Two fastening nuts are threadedly connected to the tie rod between the U-shaped clips. The fastening nuts fix the U-shaped clips to the main reinforcing bars of the reinforcing cage.

[0009] The template has mounting holes, and the two ends of the tie rod are inserted into the mounting holes on the template. A mountain-shaped clip is provided at each end of the tie rod, and the mountain-shaped clip is located on the outside of the template. A fastening nut is threaded onto each end of the tie rod, and the fastening nut fixes the mountain-shaped clip to the template.

[0010] Preferably, a positioning nut is threaded onto the middle portion of each end of the pull screw, and the positioning nut is located inside the template.

[0011] Preferably, the outer side of the template is provided with multiple vertical square timber back ribs.

[0012] Preferably, a steel pipe is inserted between the mountain-shaped clamp and the square timber back rib.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment are: 1. The reinforcement process uses physical connection without welding, which ensures the quality of the steel bars and screws;

[0014] 2. The U-shaped tie rod solves the problem of difficulty in tie rod installation for ultra-wide, irregularly shaped, and large-volume products;

[0015] 3. No welding or other operations were performed during the construction process, thus avoiding potential safety and fire hazards;

[0016] 4. The traditional method of welding to the main reinforcement was not used, which ensured the quality of the reinforcement and bolts;

[0017] 5. No welding is required for construction; ordinary workers can operate the equipment, making construction convenient, quick, and easy to learn, saving costs and time. Attached Figure Description
