Description

Technical Field

[0001] This utility model relates to the field of steel bar welding technology, specifically to a welding positioning device for ultra-large rectangular jacking pipe steel bars. Background Technology

[0002] Large-scale rectangular pipe jacking refers to rectangular pipe tunnel structures with large cross-sectional dimensions, strong load-bearing capacity, and long service life. It is mainly used in underground traffic tunnels and underground passage projects that require high load-bearing capacity and long service life, such as urban main traffic arteries. With the acceleration of urbanization and the continuous development of underground space, large-scale rectangular pipe jacking, as an efficient and environmentally friendly underground construction technology, has broad development prospects. Its key technical challenges lie in pipe section design and optimization, waterproofing and connection, ground disturbance and mutual influence, and construction control.

[0003] The interior of a rectangular jacking pipe is generally lined with a steel reinforcement skeleton. The steel reinforcement is processed according to design requirements to form a spatial mesh structure, providing the main load-bearing support for the jacking pipe. However, processing the steel reinforcement into a spatial mesh structure generally requires welding between the steel reinforcements, which necessitates the crossing of the steel reinforcements. Since the crossing steel reinforcements are in a movable state, it is inconvenient for workers to fix the two intersecting steel reinforcements during welding, making the welding process quite difficult. Therefore, we propose an ultra-large rectangular jacking pipe steel reinforcement welding positioning device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a welding positioning device for ultra-large rectangular jacking pipe reinforcement bars, so as to solve the problem mentioned in the background art that, since the intersecting reinforcement bars are in a movable state, it is not convenient for workers to fix the two intersecting reinforcement bars during welding, which makes welding more difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding positioning device for ultra-large rectangular jacking pipe reinforcing bars, comprising a first fixing plate and a second fixing plate, wherein the first fixing plate is installed above the second fixing plate;

[0006] Also includes:

[0007] A fixed locking platform is provided at the upper end of the first fixed plate, and two fixed locking platforms are provided and symmetrically distributed on both sides of the upper end of the first fixed plate.

[0009] Preferably, the second fixing plate has symmetrically distributed circular holes on both sides of its surface, and the bottom of the movable locking platform is provided with an installation rod. The installation rod extends through the circular holes to the bottom of the second fixing plate, and the installation rod and the circular holes are interference fit. The bottom of the installation rod is provided with a connecting plate, which connects the two installation rods, and the connecting plate is located at the bottom of the second fixing plate.

[0012] Preferably, the surface of the V-groove is provided with an anti-slip pad by adhesive bonding.

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

[0014] 1. By setting a first fixing plate and a second fixing plate, and setting a clamping platform at the upper end of the two fixing plates, two intersecting steel bars are placed on the two clamping platforms respectively. The clamping platforms are provided with V-shaped grooves to accommodate steel bars of different diameters. The clamping platform on the first fixing plate is attached to the surface, while the clamping platform on the second fixing plate is fixed to the surface by an installation rod. The installation rod is used to raise the distance between the clamping platform and the second fixing plate. Usually, the bottom steel bar is placed on the first fixing plate, and the top steel bar is placed on the second fixing plate, so that the intersection of the two steel bars is tightly attached, allowing workers to directly weld the two steel bars.

[0015] 2. The first and second fixing plates are connected and locked together by screws, which allows for adjustment of the angle of the two intersecting steel bars according to the site conditions. This improves flexibility, and the movable clamping platform can move up and down via the mounting rod to adjust the contact between the upper and lower steel bars according to their diameter.
