Technical Field

[0001] This utility model relates to the technical field of steel column installation adjusters, specifically to a cup-shaped foundation installation steel column jack-type tightening adjuster. Background Technology

[0002] In building structural construction, the installation of steel or concrete columns aims to ensure precise positioning, guarantee verticality, provide stable support for the upper load, achieve reasonable load transfer, and ensure the overall structural safety and stability of the building.

[0003] In traditional cup-shaped foundation designs, the installation of steel or concrete columns mainly relies on steel wedges or wooden wedges for temporary fixation. However, steel wedges need to be custom-made according to the cup opening size, and the cup opening size varies greatly from project to project. The customization process is cumbersome and costly, and the large-scale customization of steel wedges results in material waste. The column hoisting process is even more complex. Construction workers must simultaneously pay attention to the adjustment of the column position and verticality, which is difficult to operate. Furthermore, after installation, the removal of steel or wooden wedges is also difficult. Improper operation during removal can easily damage the foundation and column, affecting structural safety. To address this, a jack-type tightening adjuster for installing steel columns in cup-shaped foundations is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of poor flexibility in the traditional cup-shaped foundation design where steel or concrete columns are installed using customized steel wedges or wooden wedges for auxiliary fixing. This utility model provides a jack-type tightening adjuster for installing steel columns in a cup-shaped foundation.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A cup-shaped foundation for installing steel columns with a jack-type tightening adjuster includes a cup-shaped foundation for installing steel columns, a steel column inside the cup-shaped foundation, and two sets of symmetrically distributed adjusters inside the cup-shaped foundation.

[0007] Furthermore, the regulator includes a clamping body. Two clamping bodies are disposed inside the cup-mouth base. Each clamping body is a square tubular structure. A rotating shaft is movably installed inside the lower end of each clamping body. A stiffening plate is rotatably installed on the side of each clamping body via the rotating shaft. A jack baffle is fixedly installed inside the upper end of each clamping body. A hydraulic jack is fixedly installed on the top of each jack baffle. The input end of each hydraulic jack extends to the outside of the corresponding clamping body. Each hydraulic jack's input end is equipped with a jack for adjusting the extension / retraction state of the hydraulic jack. The top pressure rod has sliding grooves on both sides of each jack body symmetrically. Each hydraulic jack output end passes through the corresponding jack baffle. A rotating shaft is movably installed on both sides of each hydraulic jack output end. The end of each rotating shaft away from the hydraulic jack output end is placed inside the adjacent sliding groove. A rectangular groove is opened on the side wall of each jack body. A steel plate connecting rod is rotatably installed on each rotating shaft. The free end of each steel plate connecting rod passes through the interior of the rectangular groove. Two connecting blocks are fixedly installed on the inner side of each stiffening plate. The free ends of the two steel plate connecting rods are rotatably installed with the two connecting blocks respectively.

[0008] Furthermore, the regulator also includes a clamping plate, with a clamping plate fixedly installed on the outer side of each stiffening plate.

[0009] Furthermore, the regulator also includes a handle, with a handle fixedly installed at the top of each clamping body.

[0021] like Figure 1-4 As shown, a cup-shaped foundation for installing steel columns uses a jack-type tightening adjuster, comprising a cup-shaped foundation 1 for installing the steel column, a steel column 2 disposed inside the cup-shaped foundation 1, and two sets of symmetrically distributed adjusters 3 disposed inside the cup-shaped foundation 1, as shown. Figure 1-4As shown, specifically, the regulator 3 includes a clamping body 301. Two clamping bodies 301 are disposed inside the cup-mouth base 1. Each clamping body 301 is a square tubular structure. A rotating shaft 302 is movably installed inside the lower end of each clamping body 301. A stiffening plate 303 is rotatably installed on the side of each clamping body 301 via the rotating shaft 302. A jack baffle 304 is fixedly installed inside the upper end of each clamping body 301. A hydraulic jack 305 is fixedly installed on the top of each jack baffle 304. The input end of each hydraulic jack 305 extends to the outside of the corresponding clamping body 301. A jack lever 306 for adjusting the extension / retraction state of the hydraulic jack 305 is provided at the input end of each hydraulic jack 305. Symmetrical openings are provided on both sides of each clamping body 301. The sliding groove 307, the output end of each hydraulic jack 305 passes through the corresponding jack baffle 304, the two sides of the output end of each hydraulic jack 305 are respectively movably installed with a rotating shaft 308, the end of each rotating shaft 308 away from the output end of the hydraulic jack 305 is placed inside the adjacent sliding groove 307, the side wall of each jacking body 301 is provided with a rectangular groove 309, the rotating shaft 308 is rotatably installed with a steel plate connecting rod 310, the free end of each steel plate connecting rod 310 passes through the interior of the rectangular groove 309, the inner side of each stiffening plate 303 is fixedly installed with two connecting blocks 311, the free ends of the two steel plate connecting rods 310 are respectively rotatably installed with the two connecting blocks 311, the outer side of each stiffening plate 303 is fixedly installed with a jacking flap 312, and the top of each jacking body 301 is fixedly installed with a handle 313.

[0022] More specifically, first, the steel column 2 is placed inside the cup-shaped foundation 1. Then, the two clamping device bodies 301 are placed between the steel column 2 and the inner wall of the cup-shaped foundation 1, respectively, with the two clamping device bodies 301 symmetrically arranged around the central axis of the cup-shaped foundation 1. Then, the two jack levers 306 are grasped and operated, causing the output ends of the two hydraulic jacks 305 to extend downwards. When the output end of each hydraulic jack 305 extends downwards, it will drive the rotating shaft 308 connected to it to move downwards synchronously. At this time, each steel plate connecting rod 310 is subjected to corresponding... Driven by the second rotating shaft 308, the shaft gradually rotates and tends to be placed horizontally. At this time, the two ends of each steel plate connecting rod 310 rotate relative to the corresponding second rotating shaft 308 and the corresponding connecting block 311, respectively. At the same time, the sliding groove 307 can limit the lowest position of the adjacent second rotating shaft 308. Each stiffening plate 303 gradually unfolds under the push of the gradually horizontally placed steel plate connecting rod 310. At this time, each stiffening plate 303 rotates and unfolds away from the adjacent clamping body 301, so that the two clamping movable plates 312 are tightly attached to the inner wall surface of the cup mouth foundation 1, while the two clamping bodies 3 01 is tightly fitted to the side wall of steel column 2. By adjusting the angle between each jack body 301 and the adjacent stiffening plate 303, the verticality of steel column 2 can meet the construction requirements, and the position of steel column 2 can be flexibly adjusted. When temporary fixation of steel column 2 is not required, the two jack rods 306 are grasped and operated, so that the output ends of the two hydraulic jacks 305 move upward. When the output end of each hydraulic jack 305 moves upward, it will drive the rotating shaft 308 connected to it to move upward synchronously. At this time, each steel plate is connected to The rod 310 is driven by the corresponding rotating shaft 308 to gradually rotate and tend to be placed vertically. At this time, the two ends of each steel plate connecting rod 310 rotate relative to the corresponding rotating shaft 308 and the corresponding connecting block 311, respectively. At the same time, the sliding groove 307 can limit the highest position of the adjacent rotating shaft 308 to move upward. Each stiffening plate 303 gradually retracts under the push of the steel plate connecting rod 310 which gradually tends to be placed vertically. At this time, the included angle between each tightening body 301 and the adjacent stiffening plate 303 is reduced, which makes it easy to remove the entire adjuster 3 from the inside of the cup mouth base 1 for reuse.

[0023] In summary: First, the steel column 2 is placed inside the cup-shaped foundation 1. Simultaneously, both sets of adjusters 3 are placed inside the cup-shaped foundation 1, positioned between the steel column 2 and the inner wall of the cup-shaped foundation 1, symmetrically arranged around the central axis of the cup-shaped foundation 1. Then, the two sets of adjusters 3 are adjusted to appropriately extend, temporarily stabilizing the steel column 2 inside the cup-shaped foundation 1. This ensures the verticality of the steel column 2 meets construction requirements and allows for flexible adjustment of its position. During adjustment, a crane is no longer needed, reducing labor input. When temporary fixation of the steel column 2 is no longer required, the two sets of adjusters 3 can be adjusted to appropriately retract, facilitating easy removal from the cup-shaped foundation 1. This convenient removal improves construction efficiency, and the reusable adjusters 3 indirectly enhance economic benefits.
