Description

Technical Field

[0001] The utility model relates to the technical field of prestressed tendons, in particular to a supporting steel component of prestressed tendons. Background Art

[0002] Prestressed steel bars are used to apply compressive stress to the concrete of structural components before they are used, either by pre-tensioning or post-tensioning. The pre-tensioning method is to tighten the steel bars first and then pour them into the concrete. When the force reaches the required level, the steel bars will loosen and shrink. The post-tensioning method is to release the reserved holes into the concrete first, add steel bars for tensioning after forming, and then use instruments to anchor the two ends of the component. During the installation of longer prestressed steel bars, support steel components are needed to support them to prevent deformation of the steel bars. The following problems exist in the existing technology:

[0003] Because the existing support steel components are made of integrated steel structures and have a relatively simple structure, it is impossible to adjust the height at any time when supporting prestressed steel bars of different heights. For prestressed steel bars with an installation height higher than the support steel components, different support steel components can only be replaced for support, which not only has poor applicability but also increases costs.

The limit hole 24 is located on the right front side of the threaded hole 23. The support mechanism 3 includes a support plate 31, and a lifting threaded rod 32 is movably installed at the bottom center of the support plate 31. The outer wall of the lifting threaded rod 32 is threadedly connected with the inner circle of the connecting top plate 21 and the threaded hole 23. The bottom end of the lifting threaded rod 32 is fixedly installed with a limit plate 33, and a limit rod 34 is fixedly installed on the right front side of the bottom of the support plate 31. The bottom end of the limit rod 34 passes through the limit hole 24 to the bottom of the connecting top plate 21. Two spacing adjustment mechanisms 35 are arranged on the top of the support plate 31;

[0023] During installation, the two bottom plates 11 are fixed to the concrete floor below the transverse prestressed tendons by using fixed cement nails 12, and then the movable adjusting ring 22 on the top of the top plate 21 is rotated to utilize the threaded connection between the inner ring of the movable adjusting ring 22 and the threaded hole 1 23 and the lifting threaded rod 32 to drive the lifting threaded rod 32 to rise stably, and cooperate with the sliding connection between the limit rod 34 and the limit hole 24 to keep the overall support plate 31 in position when rising, and utilize the limit plate 33 at the bottom end of the lifting threaded rod 32 to prevent the lifting threaded rod 32 from falling off, until the top of the support plate 31 stably supports the bottom of the prestressed tendon.

[0024] like Figure 4The cam 352 is a block diagram of a block diagram of a cam 352 that is used to connect the cam 351 to the support frame 310 , and the cam 352 is a block diagram of a block diagram of a cam 352 that is used to connect the cam 351 to the support frame 310 .

[0025] The two movable horizontal plates 351 at the top of the support plate 31 are slid on the outer wall of the slide rod 312 in the slide groove 311 by using the movable block 352, so as to adjust the distance between the opposite surfaces of the top of the support plate 31 to make it more closely fit the left and right sides of the prestressed tendon to prevent the prestressed tendon from shaking left and right. After the adjustment, the positioning threaded rod 355 can be driven by rotating the knob 356 to rotate and move backward in the threaded hole 354 until it is threadedly connected and fixed with the positioning screw hole 313 opened on the front side of the support plate 31.

[0026] like Figure 5 As shown, a suspension rod 211 is fixedly installed on the left side of the bottom of the connecting top plate 21, an arc-shaped groove 131 is opened on the top of the left bracket plate 13, and an arc-shaped limiting plate 132 is fixedly installed on the top of the inner wall of the arc-shaped groove 131.

[0027] When the position of the prestressed tendons is offset after installation, the pentagonal bolt 134 can be rotated and removed to release the limit on the arc hanger plate 212 in the arc groove 131, so that the integral connecting top plate 21 can use the suspension rod 211 to drive the arc hanger plate 212 to slide back and forth in the arc groove 131, thereby adjusting the placement angle of the connecting top plate 21 and then re-rotating the pentagonal bolt 134 through the threaded hole three 133 to tightly press against the arc hanger plate 212 for fixing.

[0028] The following is a detailed description of the working principle of the prestressed tendon support steel structure.

[0029] like Figure 1-5As shown, during installation, the two bottom plates 11 are fixed to the concrete floor below the transverse prestressed tendons by using fixed cement nails 12, and then the movable adjusting ring 22 at the top of the top plate 21 is rotated to drive the lifting threaded rod 32 to rise stably by using the threaded connection between the inner ring of the movable adjusting ring 22 and the threaded hole 1 23 and the lifting threaded rod 32, and cooperate with the sliding connection between the limit rod 34 and the limit hole 24 to keep the overall support plate 31 unchanged when rising, and use the limit plate 33 at the bottom end of the lifting threaded rod 32 to prevent the lifting threaded rod 32 from falling off, until the top of the support plate 31 stably supports the bottom of the prestressed tendons, and at the same time, the two movable horizontal plates 351 at the top of the support plate 31 can be slid on the outer wall of the sliding rod 312 in the sliding groove 311 by using the movable block 352, so as to adjust the support plate 31 The distance between the opposite surfaces at the top makes it fit more closely to the left and right sides of the prestressed tendons to prevent the prestressed tendons from shaking left and right. After adjustment, the positioning threaded rod 355 can be driven by rotating the knob 356 to rotate and move backward in the threaded hole 354 until it is threadedly connected and fixed with the positioning screw hole 313 opened on the front side of the support plate 31. After installation, when the position of the prestressed tendons is offset, the pentagonal bolt 134 can be rotated and removed to release the limit on the arc-shaped hanging plate 212 in the arc-shaped groove 131, so that the overall connected top plate 21 can use the hanging rod 211 to drive the arc-shaped hanging plate 212 to slide back and forth in the arc-shaped groove 131, thereby adjusting the placement angle of the connected top plate 21 and then re-rotating the pentagonal bolt 134 through the threaded hole 3 133 to tightly press against the arc-shaped hanging plate 212 for fixing.
