[0022] The present application provides a description of a fine-tuning and positioning fixture for a hanging basket used in cantilever construction of a continuous beam.
[0023] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a fine-tuning and positioning fixture for the hanging basket sling in continuous beam cantilever construction, including a pad 1 and an adjustment seat 2 disposed above the pad 1. The pad 1 and the adjustment seat 2 have through holes for the sling to pass through, and the adjustment seat 2 has a pin 21 for the sling to pass through. The fine-tuning and positioning fixture also includes two sets of adjustment components 3 and two sets of support components 4.
[0024] Two sets of adjustment components 3 are set at both ends of the cushion 1 and connected to both ends of the adjustment seat 2 respectively. The adjustment components 3 are used to drive the adjustment seat 2 to rise and fall. Two sets of support components 4 are set between the cushion 1 and the adjustment seat 2 and are located on both sides of the sling respectively. The support components 4 are used to support both ends of the adjustment seat 2 after it has been raised and lowered.
[0025] This embodiment provides a continuous beam cantilever construction hanging basket sling fine adjustment and positioning fixture. Compared with the prior art, it uses two sets of adjustment components 3 respectively set at both ends of the pad 1 and connected to both ends of the adjustment seat 2, which can accurately drive the adjustment seat 2 to perform lifting and lowering operations. After the adjustment seat 2 is lifted and lowered, the support components 4 support both ends of the adjustment seat 2, which avoids the adjustment seat 2 from shaking or displacement during construction, and further enhances the stability of the entire fixture.
[0026] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjusting assembly 3 includes an adjusting screw 31 and an adjusting nut 32; the top of the adjusting screw 31 is connected to the adjusting seat 2, and the bottom is inserted into the pad 1; the adjusting nut 32 is rotatably connected to the pad 1 and threadedly connected to the adjusting screw 31.
[0027] During construction, operators can rotate the adjusting nut 32 to move the adjusting screw 31 up and down, thereby raising and lowering the adjusting seat 2. The threaded connection has good self-locking performance, which can automatically lock the position of the adjusting seat 2 after it is adjusted to a suitable height, preventing it from moving accidentally due to external forces.
[0028] Compared to traditional methods of using steel plates for height adjustment, this method is more flexible, allowing operators to make fine adjustments as needed to ensure the sling height and stress conditions meet construction requirements. Furthermore, the threaded connection is simple, reliable, easy to maintain and replace, reducing construction costs and maintenance complexity.
[0029] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The top of the adjusting screw 31 is detachably connected to the adjusting seat 2.
[0030] The detachable connection makes the installation and disassembly of the adjusting screw 31 and the adjusting seat 2 more convenient and quick, improving the flexibility and maintainability of the tooling and reducing time and labor costs during construction. At the same time, the detachable structure facilitates the handling and storage of the tooling during transportation, reducing transportation costs and difficulties.
[0031] like Figures 2 to 3As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The bottom of the adjusting seat 2 is provided with a support groove 22; the top of the adjusting screw 31 is fixed with a crossbar 5 for inserting into the support groove 22; the adjusting seat 2 is provided with a positioning component 6 for fixing the crossbar 5 into the support groove 22.
[0032] In continuous beam cantilever construction, the hanging basket sling needs to withstand a large construction load. The support groove 22 provides a stable support platform for the crossbar 5, making the connection between the adjusting screw 31 and the adjusting seat 2 tighter. The positioning component 6 further ensures that the crossbar 5 is fixed in position within the support groove 22, preventing it from shaking or shifting during construction and ensuring the structural stability of the entire fixture.
[0033] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The positioning assembly 6 includes a positioning bolt 61 and a limiting collar 62; the positioning bolt 61 is threaded to the outside of the adjusting screw 31 and is located above the support groove 22; the limiting collar 62 is sleeved on the crossbar 5 and the positioning bolt 61, with the bottom inner side of the limiting collar 62 abutting against the bottom of the crossbar 5 and the top inner side of the limiting collar 62 abutting against the top of the positioning bolt 61.
[0034] The threaded connection of the positioning bolt 61 provides excellent fastening, firmly fixing the crossbar 5 within the support groove 22. The limiting collar 62 serves a double safety function, restricting not only the vertical movement of the crossbar 5 but also preventing it from swaying horizontally.
[0035] During the cantilever construction of continuous beams, the hanging basket slings are subjected to various external forces, such as wind and vibration. This stable connection structure can effectively resist the influence of these external forces, ensuring that the connection between the adjusting seat 2 and the adjusting screw 31 will not loosen, thereby guaranteeing the normal operation of the entire fixture and the safety of construction.
[0036] like Figure 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: A compression sleeve 611 is fixedly sleeved on the positioning bolt 61, and the outer diameter of the compression sleeve 611 gradually decreases in the direction of approaching the limiting collar 62.
[0037] When the positioning bolt 61 is screwed into the adjusting seat 2, the outer conical surface of the compression sleeve 611 can compress the limiting collar 62 and apply an upward force to it, thereby enabling the limiting collar 62 to pull the crossbar 5 upward within the support groove 22, further improving the stability of the crossbar 5. This effectively prevents the connection between the adjusting screw 31 and the adjusting seat 2 from loosening, ensuring that the tooling remains stable even when subjected to large construction loads, thus improving the safety and reliability of construction.
[0038] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The support assembly 4 includes a fixed pad 41 and a support pad 42; the fixed pad 41 is fixed on the cushion 1; the support pad 42 is inserted between the fixed pad 41 and the adjusting seat 2; wherein, the surfaces of the fixed pad 41 and the support pad 42 that are in contact with each other are inclined surfaces.
[0039] The inclined surface design allows the support pad 42 to better adapt to the height changes of the adjusting seat 2 when it is inserted between the fixed pad 41 and the adjusting seat 2. During the raising and lowering of the adjusting seat 2, the support pad 42 can automatically adjust its support angle according to the position of the adjusting seat 2, thereby ensuring effective support for both ends of the adjusting seat 2.
[0040] Compared with traditional planar support structures, the inclined surface design can better distribute construction loads and improve the load-bearing capacity of support component 4. At the same time, the inclined surface structure also makes the installation and disassembly of support pad 42 more convenient, improving construction efficiency and tooling maintainability.
[0041] like Figure 1 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The top surface of the support pad 42 is flat, and scale lines (not shown in the figure) are provided along the direction in which it is inserted between the fixing pad 41 and the adjusting seat 2.
[0042] In the cantilever construction of continuous beams, precise control of the height of the adjusting seat 2 is crucial to ensuring construction quality. The scale markings allow operators to visually determine the insertion depth of the support pad 42, thus enabling precise control of the adjusting seat 2's height. Simultaneously, the scale markings facilitate inspection and adjustment during construction, ensuring the overall height and level of the fixture meet construction requirements, thereby improving construction quality and efficiency.
[0043] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
