Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a reinforcement cage welding auxiliary device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] A steel cage is a cage-like structure made of welded or tied steel bars. It is frequently used in construction and civil engineering, primarily for reinforcing concrete components such as pile foundations, columns, and walls in bridges, tunnels, and high-rise buildings. Placing the steel cage within concrete significantly improves the bearing capacity and stability of the concrete structure. The presence of the steel cage enhances the overall stiffness and seismic resistance of the concrete structure, enabling the structure to better withstand external forces during natural disasters such as earthquakes. In particular, during the construction of high-rise buildings, piling is performed according to the required foundations. Usually, a hole is first punched or drilled using a machine to achieve the required design depth. The steel cage is then lowered into the pile hole, and a guide tube is inserted for concrete pouring.

[0004] Existing rebar cages have specialized manufacturers and equipment for producing them. However, directly purchasing rebar cages increases not only construction costs but also transportation costs and the labor and effort required to transport them to the construction site. Some cages can be as long as 10-20 meters, making direct transportation inconvenient. Purchasing equipment directly is also very expensive, so most construction work is done by construction workers welding the cages. Rebar cages primarily consist of multiple main bars, stiffening hoops, and coiled bars. Traditional welding methods begin by welding the main bars to the outside of the stiffening hoops. The number of main bars and hoops varies depending on construction requirements, with a minimum of eight main bars. The hoops are spaced two meters apart, depending on the required length. The main bars are placed on a frame, then welded to each stiffening hoop. Coaxiality must be ensured for each hoop on the main axis. Main bars at the same level are then welded. Once all the main bars are welded, a layer of bent coiled bar is wrapped around the main bars, secured to the main bars, and then welded. The aforementioned welding process is difficult due to the long length of the main bars and the lack of support and restraint for the main bars and reinforcing hoops during welding. Furthermore, the 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 reinforcing hoops and the main bars to vary beyond the specified range, leading to deviations in the coaxiality of the reinforcing hoops. Therefore, a reinforcement cage welding auxiliary device is needed. Utility Model Content

[0021] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0022] The utility model is a reinforcement cage welding auxiliary device, as shown in the accompanying drawings. Figure 1 As shown, the main structure includes a support frame 1 set on the ground, two fixing devices rotatably connected to the support frame 1, a main shaft 2 for connecting the two fixing devices, and multiple tooling 3 set on the main shaft 2;

[0023] As shown in the attached figure of the instruction manual Figure 2 As shown, the fixing device includes a fixing plate 4 and a plurality of fixing sleeves 5 arranged on the fixing plate 4, and the main shaft 2 is limitedly set on the fixing device; the fixing plate 4 is rotatably connected to the support frame 1, thereby realizing relative rotation between the fixing plate 4 and the support frame 1, and the main shaft 2 is locked on the fixing plate 4 by bolts, thereby connecting the two fixing plates 4. The main function of the main shaft 2 is to bear the weight and guide the entire steel cage.

[0024] As for the fixing sleeve 5, the main function of the fixing sleeve 5 is to limit the main reinforcement 13. The fixing sleeve 5 is provided with a clearance opening 10 and a limiting hole. The fixing sleeve 5 is provided with a limiting card 11. The main reinforcement 13 is placed into the fixing sleeve 5 from the clearance opening 10. The main reinforcement 13 is limited by the limiting card 11. The limiting card 11 includes two limiting columns, which are provided with threads. A limiting opening 12 is provided between the two limiting columns. The limiting opening 12 is arc-shaped. The limiting opening 12 of the limiting card 11 is used to limit the main reinforcement 13. The limiting column of the limiting card 11 is connected to the fixing sleeve 5 through a nut, and the main reinforcement 13 is locked by the pre-tightening force of the thread. In order to make the device more adaptable as a whole and to be applicable to steel cages of different sizes, the fixing sleeve 5 must be adjustable on the fixing plate 4. Corresponding improvements are made. A sliding groove 9 is provided on the fixing plate 4. The fixing sleeve 5 cooperates with the sliding groove 9 and the fixing sleeve 5 is locked on the fixing plate 4 by a nut.

[0025] For the whole device, in addition to the main shaft 2, the component that plays a role in limiting the entire steel cage is the tooling 3, as shown in the accompanying drawings of the specification. Figure 3 and Figure 4 As shown, the tooling 3 is mainly used to connect and limit the stiffening hoop 14 and the main reinforcement 13, so as to facilitate manual welding of the stiffening hoop 14 and the main reinforcement 13. The tooling 3 is divided into an upper and lower part, both of which are sleeved on the main shaft 2 and the tooling 3 is arranged at intervals. The upper and lower parts are connected by bolts. The interval setting position of the tooling 3 is the same as the setting position of the stiffening hoop 14. The tooling 3 includes a plurality of limit grooves 6, limit plates 7 and limit members 8. The number of limit grooves 6 is the same as the number of main reinforcements 13. The main reinforcement 13 is placed in the limit grooves 6 and is limited by the limit members 8. The outer diameter of the limit plate 7 is adapted to the inner diameter of the stiffening hoop 14, and the depth of the limit groove 6 is adapted to the outer diameter of the stiffening hoop 14. The reinforcing hoop 14 is sleeved on the limiting plate 7, and then all the main bars 13 are placed in the limiting groove 6. The limiting member 8 is an iron wire or a steel wire, which is used to restrain the main bars 13 in the limiting groove 6 of the tooling 3, and then the connection between the main bars 13 and the reinforcing hoop 14 is welded. Compared with the traditional welding method, the main bars 13 and the reinforcing hoop 14 are pre-positioned by this device, which improves the accuracy of the steel cage welding process, avoids the low coaxiality accuracy of the steel cage due to manual welding, and avoids the deformation of the steel bars due to gravity due to excessive length, which leads to errors in the welding process. When the worker welds the main bars 13 and the reinforcing hoop 14, he can rotate the fixing plate 4, which reduces the difficulty of welding, thereby achieving welding without dead angles, making the welding process more convenient and simple.

[0026] As for the method of using the above-mentioned device, first connect one end of the main shaft 2 to the fixed disk 4, then place the tooling 3 and the reinforcing hoop 14 on the main shaft 2 according to the spacing, then connect the other end of the main shaft 2 to the fixed disk 4, and then respectively sleeve the reinforcing hoop 14 on the limiting plate 7; place the main reinforcement 13 to be welded in the fixed sleeve 5, limit one end of the steel bar by the limiting card 11, and then tie the main reinforcement 13 into the limiting groove 6 of the tooling 3 by the limiting piece 8, and then weld the main reinforcement 13 and the reinforcing hoop 14. During the welding process, the welding position can be adjusted by rotating the fixed disk 4, thereby facilitating welding. The above device and manual cooperation can complete the main steps in the steel cage welding process: welding the main reinforcement 13 of the steel cage with the reinforcing hoop 14.

[0027] In summary, this device is used to provide auxiliary support during the welding process of the welding cage, which changes the traditional welding method of the steel cage. The three-position limit method of the tooling is adopted to reduce the difficulty of welding the steel cage, and the welding process is more convenient. The welded steel cage has higher precision. Workers can rotate the steel cage during the welding process, which makes welding more convenient, saves effort and has no dead angles.
