Description

Technical Field

[0001] This utility model relates to the field of prestressed pipe pile technology, specifically a prestressed pipe pile installation bracket. Background Technology

[0002] PHC pipe piles, or prestressed high-strength concrete pipe piles, are hollow cylindrical precast concrete components made by using a pre-tensioned prestressed centrifugal molding process and steam curing at about 10 atmospheres (about 1.0 MPa) and 180°C.

[0003] During the installation of pipe piles, when a single precast pile cannot meet the length requirements, it is often necessary to precast sections and weld them together. In order to ensure the quality of multi-section pile splicing, the next section of the pipe pile also needs to be temporarily fixed during the splicing construction.

[0004] Currently, during the installation of precast pipe piles, cranes are typically used without releasing the hook, or only steel pipes are used for temporary auxiliary fixation and positioning. However, this hoisting method carries significant safety risks, making it impossible to guarantee the quality of pile splicing and the control of pile verticality. Furthermore, if there are no supporting and fixing measures for the grouting pipes during high-pressure grouting around the pipe piles, it is difficult to ensure that the grouting is carried out evenly and symmetrically, affecting the installation quality of the pipe piles. Therefore, a prestressed pipe pile installation bracket is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a prestressed pipe pile installation bracket, which has advantages such as improved installation quality and solves the problem of difficulty in ensuring installation quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prestressed pipe pile installation bracket, comprising a set of support plates, wherein a set of vertical rods is fixedly connected to the upper surface of each support plate, and a lifting plate is slidably connected to each set of vertical rods;

[0007] The lifting plate is equipped with a support component for supporting the limiting pipe pile;

[0008] The support includes four sliding plates that are symmetrically slidably connected to the opposite side of the two lifting plates. Each sliding plate has a limit plate fixedly connected to its upper surface. Each limit plate is arc-shaped and has L-shaped ends. One end of the two limit plates on the same side is equipped with an adjusting bolt that penetrates the limit plate and the lifting plate, and the other end of the two limit plates on the same side is equipped with a fixing bolt that penetrates the limit plate.

[0009] The lifting plate has mounting holes for adjusting bolts, and the lower surface of the lifting plate has adjusting holes for limiting adjusting bolts, and the mounting holes and adjusting holes are connected to each other.

[0010] The support plate is equipped with an adjusting component for adjusting the lifting of the lifting plate.

[0011] Furthermore, the mounting hole is elongated, and there are several adjustment holes, which are equidistantly distributed on the lifting plate and communicate with the mounting hole.

[0012] Furthermore, a support plate is fixedly connected to the outer surface of each of the limiting plates, and a number of reinforcing ribs are fixedly connected between each of the limiting plates and the support plate.

[0013] Furthermore, a slider with one end extending into the interior of the lifting plate is fixedly connected to the side of the slide plate near the lifting plate, and a groove for the slider to slide is provided on the side of the lifting plate near the slide plate.

[0014] Furthermore, the connection between the sliding plate and the limiting plate is arc-shaped, and the arc-shaped parts of the sliding plate and the limiting plate are flush.

[0015] Furthermore, the adjusting component includes a threaded rod rotatably connected to the support plate, an adjusting block threadedly connected to the threaded rod, and the adjusting block slidably connected to the support plate. The upper end of the adjusting block is hinged to an adjusting rod with one end hinged to the lifting plate.

[0016] Furthermore, the adjusting block has a threaded hole in the middle, and the threaded hole is adapted to the thread on the outside of the threaded rod.

[0017] Furthermore, each of the support plates is fixedly connected to support blocks on both its front and rear sides, and each support block is slidably connected to a screw that passes through the support block at the end away from the support plate.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. This prestressed pipe pile installation bracket, after fixing the limiting plate on the outer surface of the pipe pile with adjusting bolts and fixing bolts, can support and limit the pipe pile during the grouting construction process. By adjusting the height of the limiting plate with adjusting parts, it can support and limit the upper pipe pile during the splicing process of two pipe piles, so as to improve the verticality of the pipe pile during the installation process and thus improve the installation quality of the pipe pile.

[0020] 2. The prestressed pipe pile installation bracket has a support plate that is fixed to the support block by screws. Therefore, the left and right distance between the two support plates can be adjusted by screws, and the front and rear distance between the two limit plates can be adjusted by adjusting bolts in conjunction with the mounting holes and limit holes on the lifting plate to meet the installation of pipe piles of different specifications, thereby improving the adaptability of the entire bracket.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 In this embodiment, a prestressed pipe pile installation bracket includes a set of support plates 1. Each support plate 1 has a set of vertical rods 2 fixedly connected to its upper surface, and each set of vertical rods 2 has a lifting plate 3 slidably connected to it.

[0028] The lifting plate 3 is equipped with a support component 4 for supporting the limiting pipe pile.

[0029] In this embodiment, the support members on the lifting plate 3 facilitate the operator to provide auxiliary support during the installation of the pipe pile, thereby improving the stability of the pipe pile installation.

[0030] It should be noted that the support plate 1 is provided with an adjusting component 5 for adjusting the lifting plate 3; the adjusting component 5 includes a threaded rod 53 rotatably connected to the support plate 1, an adjusting block 51 threadedly connected to the threaded rod 53, and the adjusting block 51 slidably connected to the support plate 1. The upper end of the adjusting block 51 is hinged to an adjusting rod 52, one end of which is hinged to the lifting plate 3. When the adjusting block 51 is moved closer to or further away from the lifting plate 3 by rotating the threaded rod 53, the lifting plate 3 can be lifted or pulled by the adjusting rod 52 for adjustment.

[0031] The adjusting block 51 has a threaded hole in the middle, and the threaded hole is adapted to the thread on the outside of the threaded rod 53, so that the rotating threaded rod 53 can drive the adjusting block 51 to move laterally along the horizontal plane for adjustment.

[0032] In addition, each support plate 1 is fixedly connected to a support block 6 on both the front and rear sides. Each support block 6 is slidably connected to a screw 7 that passes through the support block 6 at the end away from the support plate 1. After the spacing between the two support plates 1 is determined, the support plates 1 can be supported and fixed by tapping the screw 7 on the support block 6 to extend into the ground.

[0033] Please see Figure 2-4 In this embodiment, the support member 4 includes four sliding plates 46 that are symmetrically slidably connected to the opposite side of the two lifting plates 3. Each sliding plate 46 has a limit plate 41 fixedly connected to its upper surface. Each limit plate 41 is arc-shaped and both ends of the limit plate 41 are L-shaped. One end of the two limit plates 41 on the same side is equipped with an adjusting bolt 42 that penetrates the limit plate 41 and the lifting plate 3. The other end of the two limit plates 41 on the same side is equipped with a fixing bolt 43 that penetrates the limit plate 41.

[0034] The lifting plate 3 has a mounting hole 48 for adjusting the adjusting bolt 42, and the lower surface of the lifting plate 3 has an adjusting hole 49 for limiting the adjusting bolt 42, and the mounting hole 48 and the adjusting hole 49 are connected to each other.

[0035] In this embodiment, after the limiting plate 41 fitted on the outer surface of the pipe pile is fixed by adjusting bolt 42 and fixing bolt 43, the pipe pile can be supported and limited during the grouting construction process. By adjusting the height of the limiting plate 41 by adjusting component 5, the upper pipe pile can be supported and limited during the splicing process of two pipe piles, so as to improve the verticality of the pipe pile during the installation process and thus improve the installation quality of the pipe pile.

[0036] It should be noted that the mounting hole 48 is elongated, and there are several adjustment holes 49. These adjustment holes 49 are equidistantly distributed on the lifting plate 3 and communicate with the mounting hole 48, so that the adjustment bolt 42 passing through the mounting hole 48 can fix one end of the limiting plate 41 to the lifting plate 3. At the same time, the elongated mounting hole 48 can be adjusted back and forth by the adjustment bolt 42 to adjust the front and back fixed position of the limiting plate 41 on the lifting plate 3.

[0037] Each limiting plate 41 has a support plate 44 fixedly connected to its outer surface, and several reinforcing ribs 45 are fixedly connected between each limiting plate 41 and the support plate 44. The support strength of the limiting plate 41 when supporting the pipe pile is improved by the several reinforcing ribs 45.

[0038] In addition, a slider 47 with one end extending into the interior of the lifting plate 3 is fixedly connected to the side of the skateboard 46 near the lifting plate 3. The side of the lifting plate 3 near the skateboard 46 is provided with a groove for the slider 47 to slide. The slider 47, which extends into the groove and can slide back and forth, improves the stability of the skateboard 46 sliding on the lifting plate 3.

[0039] Secondly, the connection between the sliding plate 46 and the limiting plate 41 is arc-shaped, and the arc-shaped parts of the sliding plate 46 and the limiting plate 41 are flush, so that the sliding plate 46 and the limiting plate 41 can jointly support the pipe pile that needs auxiliary support and fixation.

[0040] The working principle of the above embodiments is as follows:

[0041] When the pipe pile is installed into the pile hole or when concrete needs to be poured, the limiting plates 41 on both sides of the sliding plate 46 can be attached to the pipe pile. Then, the adjusting bolts 42 and fixing bolts 43 are fixed in sequence to lock and fix the two ends of each limiting plate 41. Then, the screws 7 on the support block 6 are hammered to support and fix the support plate 1, so that the limiting plates 41 attached to and supporting the pipe pile can support and limit the pipe pile, thereby improving the verticality of the pipe pile during the installation process.

[0042] After the pipe piles are fixed, when it is necessary to connect two pipe piles, first loosen the two sets of adjusting bolts 42 and fixing bolts 43, then rotate the threaded rod 53 to move the adjusting block 51 towards the side closer to the lifting plate 3, lift the lifting plate 3, and drive the limiting plate 41 on the sliding plate 46 to rise. After the limiting plate 41 is in contact with the outer surface of the end of the next pipe pile connection, fix the two sets of adjusting bolts 42 and fixing bolts 43 again to provide auxiliary support for the next pipe pile during the connection process, so as to improve the connection effect.

[0043] Since the support plate 1 is fixedly installed by the screws 7 on the support block 6, the left and right distance between the two support plates 1 can be adjusted by the screws 7, and the front and rear distance between the two limit plates 41 can be adjusted by adjusting the bolts 42 in conjunction with the mounting holes 48 and limit holes 49 on the lifting plate 3, so as to meet the installation of pipe piles of different specifications and thus improve the adaptability of the entire support.
