Description

Technical Field

[0001] This invention relates to the field of cryogenic storage tank technology, and in particular to a circumferential embedded part installation and reinforcement system for cryogenic storage tanks. Background Technology

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

[0003] In the current domestic construction field of full-containment cryogenic storage tanks, the installation of circumferential embedded parts on the inner side of the outer tank wall is extremely important. If the installation error is large, it will seriously restrict the installation of the moisture-proof plate on the inner side of the cryogenic storage tank and affect the construction quality of the storage tank.

[0004] Conventional methods for installing embedded parts involve using steel wire or iron wire to fix the circumferential embedded parts to the inner reinforcing bars. After adjustment, the steel wire or iron wire may not be able to secure the embedded parts firmly, causing them to loosen and fall. This results in a shift in the radius and elevation of the embedded parts. Furthermore, when installing the climbing formwork, the steel wire or iron wire needs to be removed, which will cause the embedded parts to shift in radius and elevation again, ultimately affecting the installation of the moisture-proof board.

[0005] Therefore, given the characteristic that the length of the circumferential embedded part of the cryogenic storage tank is around the inner side of the tank wall, conventional embedded part installation techniques will cause the circumferential embedded part to shift during installation, resulting in the subsequent moisture-proof board not being able to be installed in place, and thus failing to meet the installation and reinforcement conditions of the ultra-long circumferential embedded part on the outer wall of the cryogenic storage tank. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the primary objective of this invention is to provide a circumferential embedded part installation and reinforcement system for cryogenic storage tanks. This system employs an external reinforcement device to fix the embedded parts to the reinforcing bars, preventing them from falling or shifting. The system also forms an arc shape along the tank wall and can be adjusted vertically and horizontally according to the position of the embedded parts, ensuring the stability of the circumferential embedded parts.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] A system for reinforcing circumferential embedded parts in a cryogenic storage tank includes an external reinforcement device and an internal reinforcement device. The external reinforcement device includes a square timber that is tightly attached to the circumferential embedded part. A high-strength screw passes through the square timber and the upper and lower sides of the circumferential embedded part. A steel bar hook is provided at the bottom of the high-strength screw, and the steel bar hook is hung on the steel mesh of the tank wall. The internal reinforcement device is fixedly connected to the circumferential embedded part.

[0009] Furthermore, a nut is threaded onto the top of the high-strength screw.

[0010] Furthermore, it also includes an internal reinforcement device, which comprises a vertical support and a horizontal support.

[0011] Furthermore, the vertical and horizontal supports are welded to the rivets of the circumferential embedded parts.

[0012] Furthermore, the vertical support is composed of multiple vertical steel bars.

[0013] Furthermore, the transverse support is composed of multiple transverse steel bars.

[0014] Furthermore, the vertical support and the horizontal support together form a grid-shaped support.

[0015] Furthermore, the steel bar hook is formed by bending the steel bar by 135°.

[0016] Furthermore, a nut is threaded onto the top of the high-strength screw.

[0017] The method of using the above-mentioned circumferential embedded part installation and reinforcement system for cryogenic storage tanks includes the following steps:

[0018] Install the circumferential embedded parts, and use processed pine wood to fix the circumferential embedded parts to the steel mesh with high-strength screws;

[0019] After the circumferential embedded parts are installed, a laser total station is used to check the installation elevation of the circumferential embedded parts;

[0020] If the radius and elevation of the embedded parts do not meet the requirements during the inspection, loosen the external reinforcement device and adjust the radius and elevation of the circumferential embedded parts.

[0021] After the radius and elevation of the circumferential embedded part are adjusted, tighten the high-strength bolts and press the pine wood tightly against the circumferential embedded part to prevent displacement or detachment of the circumferential embedded part;

[0022] After all the circumferential embedded parts have been adjusted and tightened with high-strength bolts, the internal reinforcement device is welded to the anchor nails of the embedded parts.

[0023] After all the internal reinforcement devices are installed, the radius and elevation of the embedded parts are measured again to check for any displacement.

[0024] After all the circumferential embedded parts have been adjusted, the external reinforcement technology device is removed.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1) This invention utilizes an external reinforcement device. A high-strength screw passes through the square timber and the upper and lower sides of the annular embedded part. The bottom of the high-strength screw is equipped with a steel bar hook, which hangs on the steel mesh of the tank wall. By utilizing the adjustable properties of the high-strength screw and square timber assembly, the position of the annular embedded part can be adjusted at any time, improving the installation quality of the annular embedded part and achieving the high-precision and high-standard installation requirements of ultra-long embedded parts. By utilizing the characteristics of external reinforcement technology, which can be both tightened and flexibly adjusted, the installation progress can be effectively accelerated, realizing the rapid and efficient installation of ultra-long embedded parts and significantly improving the efficiency of embedded part installation.

[0027] 2) This invention utilizes the stable and reliable performance of internal reinforcement technology, which ensures that the circumferential embedded parts are not affected during concrete pouring, improves the stability of the embedded parts during concrete vibration, and allows workers to smoothly remove external reinforcement technology, thus providing conditions for the subsequent installation of climbing formwork.

[0038] Example 1

[0039] A system for reinforcing circumferential embedded parts of a cryogenic storage tank includes an external reinforcement device and an internal reinforcement device. The external reinforcement device includes a square timber 2, which is tightly attached to the annular embedded part 1. A high-strength screw 8 passes through the square timber and the upper and lower sides of the annular embedded part. A steel bar hook 5 is provided at the bottom of the high-strength screw, and the steel bar hook is hung on the steel mesh 3 of the tank wall. The internal reinforcement device is fixedly connected to the annular embedded part.

[0040] Specifically, the external reinforcement device uses 80mm*50mm*400mm square timber with two φ18 round holes. The square timber is tightly attached to the circumferential embedded part. A φ16 high-strength screw rod is passed through the φ18 round holes, and a φ12 steel bar is welded to the other end of the high-strength screw rod. The steel bar is made into a 135° hook. The steel bar hook is hung on the steel mesh of the tank wall, and the high-strength screw rod is fixed firmly with a mountain-shaped clamp 9.

[0041] More specifically, the square timber has two φ18 round holes with a spacing of 300mm between them, and the φ16 high-strength screw is longer than 300mm.

[0042] The high-strength screw is welded to a φ12 steel bar on the other end. The welding is double-sided and the welding length is 80mm.

[0043] The φ12 steel bar needs to be bent at 135° to form a steel bar hook 5, and the straight section of the steel bar is 80mm long.

[0044] The steel bar hooks are hung on the steel mesh on the tank wall, and the tie rods are fixed in place by nuts and U-shaped clips, which also locates the embedded parts.

[0045] After the external reinforcement device installs the circumferential embedded part into place, the internal reinforcement device is used for stable fixation. The external reinforcement device is a temporary adjustable device, while the internal reinforcement device is a fixed permanent device.

[0046] The internal reinforcement device includes a vertical support and a horizontal support, which are welded to the rivets of the circumferential embedded part.

[0047] The vertical support is composed of multiple vertical steel bars, and the horizontal support is composed of multiple horizontal steel bars.

[0048] Specifically, the vertical and horizontal supports are made of φ14 horizontal steel bars 6 and vertical steel bars 7, with a length of 800mm for both the horizontal and vertical supports.

[0049] Example 2

[0050] The method of using the above-mentioned circumferential embedded part installation and reinforcement system for cryogenic storage tanks includes the following steps: Step 1: First, install the circumferential embedded parts, and use processed pine wood to fix the circumferential embedded parts to the steel mesh using high-strength bolts. Multiple pine wood reinforcements make the circumferential embedded parts form an arc shape along the tank wall. Step 2: After all the circumferential embedded parts are installed, use a laser total station to check the installation elevation of the circumferential embedded parts;

[0051] Step 3: During the inspection, if the radius and elevation of the embedded parts do not meet the requirements, loosen the external reinforcement device and adjust the radius and elevation of the circumferential embedded parts;

[0052] Step 4: After adjusting the radius and elevation of the circumferential embedded part, tighten the high-strength bolts and press the pine wood tightly against the circumferential embedded part to prevent displacement or detachment of the circumferential embedded part;

[0053] Step 5: After all the circumferential embedded parts have been adjusted and tightened with high-strength bolts, install the internal reinforcement device to weld the support steel bars to the anchors of the embedded parts. At the same time, use transverse support steel bars to tightly adhere to the steel mesh of the tank wall and weld them to the anchors of the embedded parts.

[0054] Step Six: After all the internal reinforcement devices are installed, measure the radius and elevation of the embedded parts again to check for any displacement or other issues on site;

[0055] Step 7: After all the circumferential embedded parts have been adjusted, remove the external reinforcement devices to prepare for the subsequent installation of the climbing formwork.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
