Description

Technical Field

[0001] This utility model relates to the field of construction engineering, specifically a welding fixture for steel cages. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] A reinforcing cage is a cage-like structure made of welded or tied reinforcing bars, frequently used in building and civil engineering. It is primarily used to reinforce concrete components such as the pile foundations, columns, and walls of bridges, tunnels, and high-rise buildings. By placing the reinforcing cage within concrete, the load-bearing capacity and stability of the concrete structure can be significantly improved. The presence of the reinforcing cage enhances the overall stiffness and seismic performance of the concrete structure, enabling it to better resist external forces during natural disasters such as earthquakes. Especially during the construction of high-rise buildings, the foundation piling process typically involves first using machine drilling or water-jet drilling to reach the designed hole depth, then lowering the reinforcing cage into the hole and inserting a guide pipe for concrete pouring.

[0004] For existing rebar cages, there are specialized manufacturers and equipment. However, directly purchasing rebar cages during construction not only increases construction costs but also transportation costs and makes transporting them to the construction site time-consuming and laborious, as some rebar cages are quite long, reaching 10-20 meters, making direct transportation inconvenient. Directly purchasing equipment is also very expensive. Therefore, in most construction processes, welding is done by construction workers. Rebar cages mainly consist of multiple main bars, stiffening hoops, and coiled bars. Traditional welding methods involve first welding the main bars to the outside of the stiffening hoops. The number of main bars and stiffening hoops varies depending on construction requirements, but at least eight main bars are required. The stiffening hoops are spaced two meters apart according to length requirements. During welding, the main bars are first placed on a scaffold, and then welded to each stiffening hoop, ensuring coaxiality of each stiffening hoop on the main axis. After welding, the main bars at the same horizontal position are welded together. After all the main bars are welded, a bent coiled bar is wrapped around the outside of the main bars and tied to the main bars before welding. For the above welding process, the main reinforcement bars are quite long, and the main reinforcement bars and stiffening hoops lack support and restraint during welding, making welding difficult. The reinforcement bars themselves may not be straight, and because they are long and heavy, they may bend under gravity. This can easily cause the angle between the stiffening hoops and the main reinforcement bars to change improperly, resulting in deviations in the coaxiality of the stiffening hoops. Therefore, a welding fixture for reinforcing cages is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a welding fixture for steel cages, which is used in the welding of steel cages to realize the pre-connection of the main bars and stiffening hoops, limit the position of the main bars and stiffening hoops, reduce the welding difficulty, simplify the welding process of steel cages, and make the welded steel cages more accurate.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A welding fixture for a steel cage includes upper and lower parts, which are detachable. The fixture includes multiple limiting grooves, limiting plates, and limiting components. The main reinforcement bars are placed in the limiting grooves and limited by the limiting components. The outer diameter of the limiting plate is adapted to the inner diameter of the stiffening hoop, and the depth of the limiting groove is adapted to the outer diameter of the stiffening hoop.

[0008] The number of limiting grooves is the same as the number of main reinforcing bars.

[0009] The upper and lower parts of the tooling are locked together by a threaded connection.

[0010] The tooling has a central hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Used in the welding of steel cages, it enables the pre-connection of main bars and stiffening hoops, limits the main bars and stiffening hoops, reduces the welding difficulty, simplifies the welding process of steel cages, and results in higher precision steel cages after welding.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0021] This utility model describes a welding fixture for a rebar cage. Fixture 1 is sleeved on the main shaft 7 of a fixing device. The main structure of the fixing device is as follows: The fixing device includes a fixing plate 8 and multiple fixing sleeves 9 set on the fixing plate 8. The main shaft 7 is limited and set on the fixing device. The fixing plate 8 and the support frame are rotatably connected through a rotating shaft and bearing, so that the fixing plate 8 and the support frame rotate relative to each other. The main shaft 7 is locked to the fixing plate 8 by bolts, thereby connecting the two fixing plates 8. The main function of the main shaft 7 is to bear the weight and guide the entire rebar cage. As for the fixing sleeves 9, the main function of the fixing sleeves 9 is to limit the main reinforcement 5.

[0022] For tooling 1, the main purpose is to connect and limit the stiffening hoop 6 to the main reinforcement 5, so that it is easy for workers to weld the stiffening hoop 6 to the main reinforcement 5. Then, by rotating between the fixing device plate 8 and the support frame, the main reinforcement 5 and the stiffening hoop 6 can be limited, and different angles can be rotated, which makes it easier for workers to weld.

[0023] The fixture 1 is divided into upper and lower parts. The fixture 1 has a central hole through which it is fitted onto the spindle 7. Multiple fixtures 1 are spaced apart on the spindle 7. The upper and lower parts of the fixture 1 are detachable and connected by bolts. The spaced positions of the fixture 1 are the same as those of the stiffening hoops 6. The fixture 1 includes multiple limiting grooves 2, limiting plates 3, and limiting elements 4. The number of limiting grooves 2 is the same as the number of main ribs 5. The main ribs 5 are placed in the limiting grooves 2 and limited by the limiting elements 4. The outer diameter of the limiting plate 3 matches the inner diameter of the stiffening hoops 6, and the depth of the limiting groove 2 matches the outer diameter of the stiffening hoops 6. The stiffening hoops 6 are fitted onto the limiting plates 3, and then all the main ribs 5 are placed in the limiting grooves 2. The limiting elements 4 are made of iron or steel wire and are used to bind the main ribs 5 within the limiting grooves 2 of the fixture 1. Finally, the connection between the main ribs 5 and the stiffening hoops 6 is welded. Compared to traditional welding methods, this device pre-positions the main reinforcement 5 and the stiffening hoop 6, improving the precision of the steel cage welding process. It avoids errors caused by manual welding, such as low coaxiality of the steel cage and deformation due to gravity caused by excessively long reinforcement bars. When workers weld the main reinforcement 5 and the stiffening hoop 6, the fixed plate 8 can be rotated, reducing the welding difficulty and achieving welding without dead angles, making the welding process more convenient and simple.

[0024] In summary, this device is used in the welding of steel cages to achieve pre-connection of the main reinforcement 5 and the stiffening hoop 6, limit the position of the main reinforcement 5 and the stiffening hoop 6, reduce the welding difficulty, simplify the welding process of steel cages, and result in a more precise welded steel cage.
