Description

Technical Field

[0001] This invention relates to the field of welding tooling technology, and in particular to auxiliary tooling for preventing deformation of embedded parts in the outer tank liner of an LNG full-containment prestressed concrete storage tank. Background Technology

[0002] In the construction of full-containment LNG storage tanks, the liner plates are installed on the liner plate embedded parts. The embedded parts in the outer tank wall liner plate are used to improve the structural strength of the tank. The number of embedded parts varies depending on the tank capacity design requirements. The installation of embedded parts involves a significant amount of work during tank assembly. Traditional jigs and fixtures are typically welded, resulting in slow adjustments to assembly gaps and verticality. Post-weld fixture removal and weld bead treatment can easily damage the base material and are also extensive and slow-moving. Conventional anti-deformation fixtures use welded fixtures such as through-hole square iron and wedge iron. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses an auxiliary tooling for preventing deformation of embedded parts in the outer tank liner of an LNG full-containment prestressed concrete storage tank. The tooling includes a bent rod with a bend in the middle. A crossbar is fixedly connected to both the end and middle of the bent rod in the same direction. A nut is fixedly connected to one of the end crossbars, and a threaded rod is threaded into the middle of the nut. A retaining plate is fixedly connected to one end of the threaded rod. Rotating the threaded rod allows it to move back and forth. Furthermore, the tooling has a simple overall structure and can be welded from steel bars, bolts, nuts, and other components during on-site construction.

[0004] The tooling also includes a wrench, which comprises a plate with a locking jaw at one end. The jaw engages with a locking plate. By using the wrench to engage the locking plate, the screw is rotated, causing the bevel of the embedded part to be subjected to outward force, which is opposite to the stress during the welding process, thus controlling welding deformation. The same wrench can be obtained by cutting a steel plate.

[0005] Preferably, a protruding post is fixedly connected to the end of the crossbar located at the end, and a connecting rod is sleeved on the protruding post, with the end of the connecting rod bent. When the fixture is in use, the connecting rod is assembled onto the crossbar, thereby increasing the structural strength of the fixture. At the same time, the protruding post and the bent end of the connecting rod facilitate quick assembly and disassembly.

[0006] The beneficial effects of this invention are as follows:

[0007] 1. This tooling has a simple structure and can be made using on-site materials, which is beneficial for construction operations.

[0008] 2. This tooling has the advantages of fast installation, convenient and quick disassembly after welding, no damage to the base material, good weld formation, and high inspection pass rate. Attached Figure Description

[0016] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0017] like Figures 1 to 4 As shown, the anti-deformation auxiliary tooling for the embedded parts of the outer tank liner of the LNG full-containment prestressed concrete storage tank includes a bent rod 2. The bent rod 2 is bent in the middle. The ends and middle of the bent rod 2 are fixedly connected to the crossbars 1 in the same direction. The three crossbars 1 are fixedly connected to the bent rod 2 by welding. One of the crossbars 1 at the end is fixedly connected to a nut 4. The nut 4 is also fixed to the top connecting rod by welding. The middle of the nut 4 is threadedly connected to a screw rod 5. One end of the screw rod 5 is fixedly connected to a clamping plate 3. The clamping plate 3 is also welded and fixedly connected to the screw rod 5.

[0018] The tooling also includes a wrench 8, which consists of a plate 81. One end of the plate 81 is provided with a jaw 82, which engages with a clamping plate 3. The wrench 8 can be made from scrap steel plate. By using the wrench 8 to clamp the clamping plate 3, the screw 5 can be rotated.

[0019] A protruding post 7 is fixedly connected to the end of the end crossbar 1. A connecting rod 6 is sleeved on the protruding post 7, and the end of the connecting rod 6 is bent. The bent structure is sleeved on the protruding post 7, thereby improving the overall structural strength of the tooling.

[0020] The bent rod 2 is installed on the embedded part, so that the bevel of the embedded part is subjected to outward force, which is opposite to the inward stress generated by welding, thus effectively controlling welding deformation.

[0021] Tooling principle: such as Figure 4 As shown, the tooling is used to weld and position two embedded parts. A steel plate is pre-welded to the back of one of the embedded parts. Then, the tooling is installed from one side of the embedded part, with the middle crossbar 1 abutting against the steel plate on the back. The upper and lower crossbars 1 are located in front of the embedded part, respectively. Then, the wrench 8 is used to hold the clamping plate 3, and the screw 5 is rotated so that the end of the screw 5 abuts against the embedded part. By adjusting the screw 5 to move forward or backward, the relative position of the two embedded parts is adjusted. Finally, the embedded parts are welded and ground.

[0022] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
