[0001] The utility model relates to the technical field of folding line pre-tensioning process equipment, in particular to a tensioning pedestal used in the folding line pre-tensioning process. Background Art
[0002] Prestressed concrete refers to a method of applying prestress to concrete components during prefabrication to improve their crack resistance and avoid premature cracks in them. The method of prestressing steel strands before pouring concrete is called pre-tensioning.
[0003] When the precast beam is prepared by the pre-stressing method, the tensioning pedestal used has a complex structure and has great limitations in use. The tensioning pedestal itself is heavy and there is great resistance to moving the tensioning pedestal during tensioning. It is generally lifted and moved by a crane or loader, or by a gantry crane. It takes a lot of time to align and adjust the position, resulting in high investment costs and low work efficiency.
[0004] Therefore, the prior art needs to be improved. Utility Model Content
[0005] The technical problem to be solved by the utility model is that the investment cost of the tensioning pedestal in the prior art is relatively large and the work efficiency is also relatively low. The purpose is to provide a tensioning pedestal for the folding line pre-tensioning process, which adopts corresponding technical means and has the beneficial effects of no need for lifting mechanical assistance, low investment cost and high work efficiency.
[0006] The utility model is realized by the following technical solutions:

When in use, the transverse moving seat drives the movable beam to move to the corresponding prestressed construction position, and then the steel strand passes through the fixed beam and the movable beam, and one end of the pusher is connected to the fixed beam and the other end is connected to the movable beam. The pusher begins to apply thrust to the movable beam, and the longitudinal moving seat begins to move longitudinally, increasing the distance between the fixed beam and the movable beam. The tensioning process applies prestress to the steel strand, thereby improving the performance of prefabricated concrete components. There is no need to use lifting machinery to assist, which reduces investment costs.
[0009] Furthermore, in the utility model, a longitudinal track is also included, and a first roller moving along the longitudinal track is provided at the bottom of the longitudinal movable seat.

When in use, the transverse movable seat drives the movable beam to move to the corresponding prestressed construction position, and then the steel strand passes through the fixed beam and the movable beam, one end of the pusher is connected to the fixed beam, and the other end is connected to the movable beam. The pusher starts to apply thrust to the movable beam, and the longitudinal movable seat starts to move longitudinally, increasing the distance between the fixed beam and the movable beam.

[0033] Example
[0034] This embodiment provides a tensioning platform for a folding line pre-tensioning process, such as Figure 1-Figure 4 As shown, the specific structure is as follows.
[0035] Please refer to Figure 1 As shown, the tensioning platform used in the fold line pre-tensioning process of this embodiment is mainly composed of five parts: a longitudinal movable seat 1, a fixed beam 2, a transverse movable seat 3, a movable beam 4 and a pushing member 5. Among them, the longitudinal movable seat 1 can move along the longitudinal direction to facilitate tensioning; the transverse movable seat 3 can move along the transverse direction to facilitate and quickly move to the next prestressed construction position; the pushing member 5 is used to stretch the steel strand 9 and apply prestress to the steel strand 9.
[0036] In some implementations of this embodiment, Figure 1 , Figure 3 and Figure 4As shown, the longitudinal moving seat 1 is composed of a metal frame, and a first roller 101 is provided at the bottom of the longitudinal moving seat 1. A plurality of longitudinal tracks 6 (three tracks are provided in this embodiment) are laid longitudinally (parallel to the direction of the steel strand 9) on the ground, and the first roller 101 is installed on the longitudinal track 6, and the first roller 101 moves along the longitudinal track 6. The first roller 101 enables the longitudinal moving seat 1 to move in a rolling manner, and the longitudinal moving seat 1 moves smoothly, which facilitates the stretching of the steel strand 9.
[0037] Further, combined with Figure 2 , Figure 3 and Figure 4 As shown, the transverse moving seat 3 is installed on the top of the longitudinal moving seat 1. A horizontal transverse track 102 is installed inside the longitudinal moving seat 1, and the middle first roller 101 is fixed to the middle position of the bottom of the transverse track 102. A second roller 301 is installed at the bottom of the transverse moving seat 3, and the second roller 301 is in contact with the transverse track 102, and the second roller 301 moves along the transverse track 102. The second roller 301 enables the transverse moving seat 3 to move in a rolling manner, and the transverse moving seat 3 moves smoothly, which facilitates the transverse moving seat 3 to move to different prestressed construction positions.
[0038] Furthermore, a brake is installed on the second roller 301 of the transverse moving seat 3, and the brake adopts a disc brake in the prior art. When it needs to be fixed, the high-pressure brake oil pushes the brake block of the disc brake to clamp the brake disc of the second roller 301 to produce a braking effect. The structure is mature, stable and reliable.
[0039] It should be noted that if Figure 3 and Figure 4 As shown, metal limit blocks 7 are welded on the tops of both ends of the transverse rail 102 to resist the second roller 301 and prevent the second roller 301 from detaching from the two ends of the transverse rail 102 .
[0040] It should be noted that the first roller 101 and the second roller 301 both adopt groove wheels in the prior art, and the longitudinal track 6 and the transverse track 102 both adopt I-beam rails in the prior art, which ensure stable operation and reduce the occurrence of derailment.
[0041] Combination Figure 1 As shown, two supporting blocks 302 are installed on the top of the transverse moving seat 3, and the top of the supporting block 302 abuts against the bottom of the pushing member 5 to play a temporary supporting role.
[0042] In some implementations of this embodiment, Figure 1 and Figure 2As shown, the movable beam 4 is fixedly installed on the top of the transverse moving seat 3. The movable beam 4 can be a metal beam or a cast beam, and the fixed beam 2 can be a metal beam or a cast beam. The fixed beam 2 is fixedly installed on the ground, and two pushers 5 are installed on the left side wall of the fixed beam 2. The pushers 5 use jacks, and the fixed ends of the pushers 5 and the fixed beam 2 are fixed by bolts. The telescopic end of the pusher 5 and the right end surface of the movable beam 4 are abutted together. When the telescopic end of the pusher 5 extends to the left, the fixed end of the pusher 5 is restricted by the fixed beam 2, so that the longitudinal moving seat 1 moves to the left along the longitudinal track 6, thereby applying prestress to the steel strand 9.
[0043] Further, combined with Figure 1 and Figure 2 As shown, in order to limit the movement of the fixed beam 2, a reaction frame 8 is installed on the right side of the fixed beam 2. The reaction frame 8 consists of three parts: a base plate 801, a baffle 802 and a diagonal brace 803, wherein two base plates 801 are installed horizontally on the ground, and a vertical baffle 802 is fixed on the left side of the base plate 801. Two diagonal braces 803 are provided, the left end of the diagonal brace 803 is fixedly connected to the baffle 802, and the right end of the diagonal brace 803 is fixedly connected to the base plate 801. The base plate 801 is fixed to the ground by cement pouring or bolts, and the left side of the baffle 802 is in contact with the right side of the fixed beam 2. When the pusher 5 applies force, the reaction frame 8 prevents the fixed beam 2 from moving rightward, thereby ensuring the stretching effect on the steel strand 9.
[0044] The working principle of the tensioning pedestal used in the folding line pre-tensioning process of the utility model is as follows:
[0045] The utility model is a tensioning pedestal for the folding line pre-tensioning process, wherein the fixed beam 2 is installed on the ground, and the movable beam 4 is installed on the transverse moving seat 3, the transverse moving seat 3 moves transversely on the longitudinal moving seat 1, and the longitudinal moving seat 1 moves longitudinally on the ground. When in use, the transverse moving seat 3 drives the movable beam 4 to move to the corresponding prestressed construction position, and then the steel strand passes through the fixed beam 2 and the movable beam 4, one end of the pusher 5 is connected to the fixed beam 2, and the other end is connected to the movable beam 4. The pusher 5 begins to apply thrust to the movable beam 4, and the longitudinal moving seat 1 begins to move longitudinally, increasing the spacing between the fixed beam 2 and the movable beam 4. The tensioning process applies prestress to the steel strand 9, thereby improving the performance of the prefabrication of concrete components. There is no need to use lifting machinery to assist, thereby reducing the investment cost. After the tensioning is completed, the transverse moving seat 3 drives the movable beam 4 to move to the next prestressed construction position, thereby realizing the rapid movement and positioning of the movable beam 4 at different prestressed construction positions, which is convenient to use and has high work efficiency.
