Description

Technical Field

[0001] This utility model relates to the field of steel strand pre-embedding technology, specifically a tool for precisely controlling the pre-embedding of prestressed steel strands. Background Technology

[0002] In the construction of prestressed concrete structures, the pre-embedding accuracy of prestressed steel strands directly determines the final stress performance, load-bearing stability and overall quality of the structure. The accuracy of their pre-embedding position, angle and spacing is the core prerequisite for ensuring the effective application of prestress.

[0003] Traditional methods of pre-embedding steel strands generally rely on manual measurement and positioning and simple binding and fixing. The traditional fixing method has a complicated operation process, requires repeated adjustments to positioning and binding reinforcement, has low construction efficiency, and has poor adaptability to fixing structures, making it difficult to flexibly meet the requirements of steel strands of different diameters and different spacings. Therefore, it is inconvenient to adjust the spacing of steel strands.

[0004] To address this problem, the present invention provides a tool for precisely controlling the pre-embedding of prestressed steel strands. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a tool for precisely controlling the pre-embedding of prestressed steel strands, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tool for precisely controlling the pre-embedding of prestressed steel strands, comprising a prestressed beam body, a support mechanism provided on the inner wall of the prestressed beam body, an adjustment mechanism slidably connected to the inner wall of the support mechanism, the support mechanism including a support plate disposed on the inner wall of the prestressed beam body, a column fixedly connected to the upper surface of the support plate, an L-shaped hollow shell slidably connected to the outer surface of the column, a first bolt threadedly connected to the outer surface of the L-shaped hollow shell, the other end of the first bolt being in contact with the outer surface of the column, the adjustment mechanism including a second movable column slidably connected to the inner wall of the L-shaped hollow shell, an arc-shaped concave block fixedly connected to the other end of the second movable column, a first movable column fixedly connected to the other end of the arc-shaped concave block, a connecting shell slidably connected to the outer surface of the first movable column, a limit through hole provided on the lower surface of the connecting shell, and steel strands slidably connected to the outer surface of the arc-shaped concave block.

[0007] Furthermore, a second limiting block is fixedly connected to the lower surface of the first movable column, the outer surface of the second limiting block is slidably connected to the inner side of the limiting through hole, and a fifth bolt is threadedly connected to the upper surface of the first movable column, the lower end of the fifth bolt being in contact with the upper surface of the first movable column.

[0008] By adopting the above technical solution, the sliding direction of the first moving column is restricted by the cooperation of the second limiting block and the limiting through hole to avoid displacement. The fifth bolt can quickly lock the position of the first moving column to ensure the stability of the structure after the spacing is adjusted and to prevent displacement during construction.

[0009] Furthermore, a third bolt is threaded onto the outer surface of the arc-shaped pressure plate, and the other end of the third bolt is in contact with the outer surface of the steel strand.

[0010] By adopting the above technical solution, the steel strand can be pressed from the outside of the arc-shaped pressure plate by the third bolt, which further enhances the fixing effect of the steel strand, prevents it from coming out or shifting under the action of external force, and ensures the accuracy of the pre-embedded position.

[0011] Furthermore, an arc-shaped pressure plate is hinged to the upper surface of the first movable column via a hinge, and a fourth bolt is threaded onto the outer surface of the arc-shaped pressure plate. The other end of the fourth bolt is threaded onto the outer surface of the second movable column.

[0012] Using the above technical solution, the arc-shaped pressure plate can be opened and closed flexibly via hinges, facilitating the placement and removal of steel strands. The fourth bolt enables the rapid fixing and unlocking of the arc-shaped pressure plate, simplifying the operation process and improving construction efficiency.

[0013] Furthermore, the outer surface of the L-shaped hollow shell is provided with a sliding groove, and the outer surface of the column is fixedly connected with a first limiting block. The outer surface of the L-shaped hollow shell is threaded with a second bolt, and the other end of the second bolt is attached to the upper surface of the second movable column.

[0014] By adopting the above technical solution, the sliding range of the L-shaped hollow shell is limited by the cooperation of the first limiting block and the sliding groove, so as to avoid excessive adjustment that could cause the structure to detach. The second bolt can lock the position of the second moving column to ensure that it can be stably fixed after the height and horizontal position are adjusted.

[0015] Furthermore, the outer surface of the first limiting block is slidably connected to the inner side of the slide groove, and the lower surface of the second moving column is fixedly connected to a limiting block that cooperates with the slide groove.

[0016] By adopting the above technical solution, the sliding stability of the adjustment mechanism is further improved through the cooperation of double limit blocks and slide grooves, avoiding jamming or deviation during the adjustment process, and ensuring adjustment accuracy and smooth operation. Beneficial effects

[0017] This invention provides a tool for precisely controlling the pre-embedding of prestressed steel strands. Compared with the prior art, it has the following advantages: 1. This precision control tool for prestressed steel strand embedding allows for flexible and precise adjustment of the horizontal spacing between two sets of arc-shaped concave blocks through the sliding engagement of the second and first moving columns. It can quickly adapt to the differentiated design requirements of steel strand spacing for different specifications of prestressed beams. Combined with the stable locking function of the second and fifth bolts, it ensures that the spacing is not easily displaced after adjustment. At the same time, the opening and closing structure of the arc-shaped concave blocks and arc-shaped pressure plates facilitates the placement and fixing of steel strands, which not only improves the versatility and adaptability of the tool, but also ensures the spacing accuracy of steel strand embedding in the construction of prestressed beams of different specifications.

[0018] 2. This precision control tool for prestressed steel strand embedding allows for flexible adjustment of the steel strand support height through the sliding engagement of the column and the L-shaped hollow shell, adapting to the construction requirements of different prestressed beams. The first bolt enables rapid locking of the height position, and the dual limiting design of the first limiting block and the sliding groove avoids over-adjustment leading to structural detachment while ensuring stability during height adjustment, effectively preventing support swaying from affecting the accuracy of the steel strand embedding height during construction.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides a tool for precisely controlling the pre-embedded prestressed steel strands, including a prestressed beam body 1. A support mechanism 2 is provided on the inner wall of the prestressed beam body 1. An adjustment mechanism 3 is slidably connected to the inner wall of the support mechanism 2. The support mechanism 2 includes a support plate 204 disposed on the inner wall of the prestressed beam body 1. A column 203 is fixedly connected to the upper surface of the support plate 204. An L-shaped hollow shell 201 is slidably connected to the outer surface of the column 203. A first bolt 202 is threadedly connected to the outer surface of the L-shaped hollow shell 201. The other end of the first bolt 202 is attached to the outer surface of the column 203. The adjustment mechanism 3 includes a second movable column 308 that is slidably connected to the inner wall of the L-shaped hollow shell 201. The other end of the second movable column 308 is fixedly connected to an arc-shaped concave block 303. The other end of the arc-shaped concave block 303 is fixedly connected to a first movable column 306. The outer surface of the first movable column 306 is slidably connected to a connecting shell 301. A limit through hole is opened on the lower surface of the connecting shell 301, and a steel strand 4 is slidably connected to the outer surface of the arc-shaped concave block 303.

[0025] Furthermore, a second limiting block 310 is fixedly connected to the lower surface of the first moving column 306, and the outer surface of the second limiting block 310 is slidably connected to the inner side of the limiting through hole. A fifth bolt 309 is threadedly connected to the upper surface of the first moving column 306, and the lower end of the fifth bolt 309 is in contact with the upper surface of the first moving column 306. A third bolt 305 is threadedly connected to the outer surface of the arc-shaped pressure plate 302, and the other end of the third bolt 305 is in contact with the outer surface of the steel strand 4. An arc-shaped pressure plate 302 is hinged to the upper surface of the first moving column 306 via a hinge. A fourth bolt 307 is threadedly connected to the outer surface of the arc-shaped pressure plate 302, and the other end of the fourth bolt 307 is threadedly connected to the outer surface of the second moving column 308.

[0026] Specifically, through the sliding engagement of the second movable column 308 and the first movable column 306, the horizontal spacing between the two sets of arc-shaped concave blocks 303 can be adjusted flexibly and precisely. This allows for quick adaptation to the differentiated design requirements of different specifications of prestressed beam body 1 for the spacing of steel strands 4. Combined with the stabilizing locking function of the second bolt 304 and the fifth bolt 309, it ensures that the spacing is not easily displaced after adjustment. At the same time, the opening and closing structure of the arc-shaped concave block 303 and the arc-shaped pressure plate 302 facilitates the placement and fixing of the steel strands 4, which not only improves the versatility and adaptability of the tool, but also ensures the spacing accuracy of the steel strands 4 pre-embedded in the construction of prestressed beams of different specifications.

[0027] Reference Figures 1 to 4 In one aspect of this embodiment, the outer surface of the L-shaped hollow shell 201 is provided with a sliding groove 206, and the outer surface of the column 203 is fixedly connected with a first limiting block 205. The outer surface of the L-shaped hollow shell 201 is threadedly connected with a second bolt 304, and the other end of the second bolt 304 is attached to the upper surface of the second movable column 308.

[0028] Furthermore, the outer surface of the first limiting block 205 is slidably connected to the inner side of the slide groove 206, and the lower surface of the second moving column 308 is fixedly connected to a limiting block that cooperates with the slide groove 206.

[0029] Specifically, the support height of the steel strand 4 can be flexibly adjusted by the sliding fit between the column 203 and the L-shaped hollow shell to adapt to the construction requirements of different prestressed beams. The height position can be quickly locked by the first bolt 202. Combined with the double limiting design of the first limiting block 205 and the slide 206, it can avoid the structure from falling off due to excessive adjustment and ensure the stability during the height adjustment process. It can effectively prevent the support from shaking during construction from affecting the pre-embedded height accuracy of the steel strand 4.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: The support mechanism 2 enables flexible adjustment of the support height of the steel strand 4. The sliding L-shaped hollow shell moves up and down along the column 203 to the required height, and the position is locked by the first bolt 202. At the same time, the first limit block 205 and the slide groove 206 cooperate to ensure the stability of the adjustment. The adjustment mechanism 3 enables precise adjustment of the spacing of the steel strand 4. The sliding second moving column 308 and the first moving column 306 drive the arc-shaped concave block 303 to change its horizontal position. The adjusted position is locked by the second bolt 304 and the fifth bolt 309 to ensure that the spacing is fixed. After the steel strand 4 is placed in the arc-shaped concave block 303, the arc-shaped pressure plate 302 is closed and fixed by the fourth bolt 307. Then, the third bolt 305 is tightened to press the steel strand 4 from the outside, forming a multi-dimensional fixation. This not only meets the pre-embedding requirements of different heights and spacings, but also effectively prevents the steel strand 4 from shifting and ensures the pre-embedding accuracy.
