Description

Technical Field

[0001] This utility model relates to the field of pipe pile technology, and in particular to a prestressed pipe pile that is easy to install. Background Technology

[0002] During the use of prestressed pipe piles, different lengths of prestressed pipe piles need to be selected according to different usage requirements. This requires prestressed pipe piles to be connected to each other to form a longer pile body.

[0003] Currently, during the construction of prestressed concrete pipe piles, it is necessary to connect two pipe piles together. The common method for connecting two prestressed concrete pipe piles is welding. Specifically, steel plates are installed at both ends of the prestressed concrete pipe piles, and the steel plates at both ends of the two prestressed concrete pipe piles are welded together. However, welding usually needs to be carried out on-site and requires external welding equipment, which makes the connection and installation of the two pipe piles inconvenient. At the same time, during the welding process, the upper pipe pile of the two pipe piles is usually hoisted by a crane, which makes it difficult to accurately align with the lower pile, further affecting the installation efficiency. Therefore, a prestressed concrete pipe pile with convenient installation is proposed to solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a prestressed pipe pile that is easy to install. By using stabilizing components and installation support components, bolt installation is adopted at the connection between two pile bodies to replace welding connection, making on-site installation more convenient and improving installation efficiency.

[0006] (II) Technical Solution

[0007] This utility model provides a prestressed pipe pile that is easy to install, including a set of pile bodies, and an end plate is installed at the joint end of the set of pile bodies;

[0008] Each of the pile bodies is provided with a stabilizing component and an installation support component at its docking end. The stabilizing component and the installation support component are used to dock and install the pile body and the end plate.

[0009] The stabilizing component includes a set of stabilizing rings, which are installed on opposite sides of the two end plates. Each set of stabilizing rings is fixedly connected to a connecting ring on the side near the end plate. Several reinforcing ribs are installed between the connecting rings and the stabilizing rings. Four sets of support bolts penetrating the end plates are installed between the set of connecting rings.

[0010] The mounting support includes a threaded rod with two sets of pipe clamps mounted on it. The two sets of pipe clamps are symmetrically distributed on opposite sides of a set of stabilizing rings. A mounting bracket is fitted onto the end of each set of pipe clamps away from the threaded rod. Two sets of connecting bolts are installed on the mounting brackets, which penetrate the pipe clamps. Each set of pipe clamps is equipped with mounting bolts that pass through the pipe clamp, the connecting ring, and the end plate in sequence. A set of abutments is fixedly connected to the side of each pipe clamp closest to the end plate.

[0011] Preferably, each of the stabilizing rings has a mounting screw installed on both its front and rear sides, with one end penetrating the stabilizing ring and extending into the pile body, and the stabilizing ring is mounted on the pile body by the mounting screw.

[0012] Preferably, four sets of support bolts are symmetrically distributed on a set of connecting rings, and both the end plate and the connecting rings have a first mounting hole for the support bolts to pass through.

[0013] Preferably, the connection end of the pipe clamp and the mounting bracket is provided with a groove for the connecting bolt to pass through, and both the groove and the mounting bracket are U-shaped.

[0014] Preferably, the mounting support further includes two support blocks that are symmetrically fixedly connected to the threaded rod. Two mounting blocks that are slidably connected to the threaded rod and fit against the support blocks are provided. The ends of the two sets of pipe clamps that are away from the mounting frame are symmetrically rotated and connected to the two mounting blocks. The upper and lower ends of the threaded rod are threadedly connected to nuts that abut against the mounting blocks.

[0015] Preferably, the number of mounting bolts is four sets, and the four sets of mounting bolts are symmetrically distributed on the two sets of pipe clamps. The pipe clamps, connecting rings and end plates are all provided with second mounting holes for the mounting bolts to pass through.

[0016] Preferably, the end of the abutment rod away from the pipe clamp is in contact with the side of the connecting ring away from the end plate.

[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0018] 1. This easy-to-install prestressed pipe pile uses four sets of pipe clamps and connecting rings that pass through the end plates in sequence to fix the pipe clamps to the outer surface of the connection ends of the two piles. Together with the stabilizing rings, connecting rings and several reinforcing ribs installed at the connection ends of the two piles, it provides stable connection and support for the connection ends of the two piles and the two end plates. During the installation process, the operator can tighten the installation bolts and support bolts instead of welding, which increases the ease of pile installation and thus improves the installation efficiency.

[0019] 2. This easy-to-install prestressed pipe pile has a pipe clamp that can rotate on the mounting block and is fastened by the mounting frame and connecting bolts. Therefore, before the mounting bolts are tightened, the connecting bolts on the mounting frame can be used to preliminarily tighten the two piles together, which makes it easy for operators to align the connecting ends of the two piles. The pipe clamp is fixed to the support block of the threaded rod by the nut, making the clamp easy to disassemble, assemble and carry, thereby further improving the overall ease of installation.

[0027] like Figure 1-3 As shown, the present invention proposes a prestressed pipe pile that is easy to install, comprising a set of pile bodies 1, and an end plate 2 installed at the joint end of the set of pile bodies 1.

[0028] A set of piles 1 are provided with a stabilizing component 3 and an installation support component 4 at their docking ends. The stabilizing component 3 and the installation support component 4 are used to dock and install the pile 1 and the end plate 2.

[0029] In this utility model, the connection between two piles 1 is made of bolts by means of the stabilizing component 3 and the installation support component 4, which replaces the welding connection and makes the on-site installation more convenient.

[0030] In an optional embodiment, the stabilizing member 3 includes a set of stabilizing rings 31, which are installed on opposite sides of the two end plates 2. Each set of stabilizing rings 31 is fixedly connected to a connecting ring 32 on the side near the end plate 2. Several reinforcing ribs are installed between the connecting rings 32 and the stabilizing rings 31. Four sets of supporting bolts 33 are installed between the set of connecting rings 32 and pass through the connecting rings 32 and the end plate 2 in sequence.

[0031] In this embodiment, the stabilizing ring 31, the connecting ring 32, and several reinforcing ribs 35 installed at the connection ends of the two pile bodies 1 provide stable connection and support for the connection ends of the two pile bodies 1 and the two end plates 2.

[0032] It should be noted that each stabilizing ring 31 has a mounting screw 34 installed on both its front and rear sides, with one end penetrating through the stabilizing ring 31 and extending into the pile body 1. The pile body 1 has screw holes for mounting the mounting screw 34 on the stabilizing ring 31. The stabilizing ring 31 is mounted on the pile body 1 by the mounting screw 34, so that the stabilizing ring 31 and the connecting ring 32 are pre-installed on the pile body 1 in front of the mounting end plate 2 by the mounting screw 34.

[0033] Among them, four sets of support bolts 33 are symmetrically distributed on a set of connecting rings 32, and the end plate 2 and the connecting ring 32 are provided with first installation holes for the support bolts 33 to pass through. By passing the four sets of support bolts 33 through the two end plates 2 that are connected in pairs, and by tightening the support bolts 33, the installation and docking end of the pile body 1 is supported and fixed.

[0034] In an optional embodiment, the mounting support 4 includes a threaded rod 41, on which two sets of pipe clamps 45 are mounted, and the two sets of pipe clamps 45 are symmetrically distributed on opposite sides of a set of stabilizing rings 31. The ends of the two sets of pipe clamps 45 away from the threaded rod 41 are fitted with mounting brackets 47. Two sets of connecting bolts 48 are mounted on the mounting brackets 47, and each set of pipe clamps 45 is fitted with mounting bolts 46 that pass through the pipe clamp 45, the connecting ring 32 and the end plate 2 in sequence. A set of abutment rods 410 are fixedly connected to the side of each pipe clamp 45 near the end plate 2.

[0035] In this embodiment, the pipe clamps 45 are fixed to the outer surface of the connecting ends of the two pile bodies 1 by four sets of pipe clamps 45 and connecting rings 32 passing through the end plates 2 in sequence. With the help of the stabilizing rings 31, connecting rings 32 and several reinforcing ribs 35 installed at the connecting ends of the two pile bodies 1, the connecting ends of the two pile bodies 1 and the two end plates 2 are stably connected and supported. During the installation process, the operator uses the fastening method of fastening the installation bolts 46 and the support bolts 33 to replace welding, so as to increase the convenience of the installation of the pile body 1 and thus improve the installation efficiency.

[0036] It should be noted that the connection end of the pipe clamp 45 and the mounting bracket 47 is provided with a groove 49 for the connecting bolt 48 to pass through. Both the groove 49 and the mounting bracket 47 are U-shaped. After the connecting bolt 48 is locked to the end of the lower set of pipe clamps 45 away from the threaded rod 41 by the mounting bracket 47, the mounting bracket 47 can be rotated and adjusted by the lower groove 49. After the two piles 1 are connected, the mounting bracket 47 can cover and fit the upper set of attached pipe clamps 45 to realize the connection limit of the two piles 1.

[0037] The installation bolts 46 are in four sets, and the four sets of installation bolts 46 are symmetrically distributed on the two sets of pipe clamps 45. The pipe clamps 45, the connecting rings 32 and the end plates 2 are all provided with second installation holes for the installation bolts 46 to pass through. The installation bolts 46 passing through the pipe clamps 45, the connecting rings 32 and the end plates 2 will fasten the pipe clamps 45, the connecting rings 32 and the end plates 2, and cooperate with the support bolts 33 to provide stable support for the pile body 1 and the end plates 2.

[0038] In addition, the end of the abutment 410 away from the pipe clamp 45 is attached to the side of the connecting ring 32 away from the end plate 2. By attaching the abutment 410 to the connecting ring 32, the end of the pipe clamp 45 away from the threaded rod 41 is fixed by the mounting bracket 47 and the connecting bolt 48 to prevent the pipe clamp 45 from shifting on the pile body 1.

[0039] In an optional embodiment, the mounting support 4 further includes two support blocks 42 that are symmetrically fixedly connected to the threaded rod 41. Two mounting blocks 44 that are slidably connected to the threaded rod 41 and fit against the support blocks 42 are also connected to the threaded rod 41. The ends of two sets of pipe clamps 45 that are away from the mounting frame 47 are symmetrically rotatably connected to the two mounting blocks 44. Both the upper and lower ends of the threaded rod 41 are threadedly connected to nuts 43 that abut against the mounting blocks 44.

[0040] In this embodiment, the end of the pipe clamp 45 away from the mounting bracket 47 and the mounting block 44 are fixed to the threaded rod 41 by the nut 43. At the same time, the pipe clamp 45 and the mounting block 44 can also be removed from the threaded rod 41 to reduce the area occupied by the pipe clamp 45 and the threaded rod 41 during transportation and increase the convenience of transportation and assembly.

[0041] The working principle in the above embodiments is as follows:

[0042] Since the stabilizing ring 31 is pre-installed on the pile body 1 by mounting screws 34 before the end plate 2 is installed on the pile body 1, when two pile bodies 1 are connected and installed through the end plate 2, the stabilizing ring 31, the connecting ring 32 and the end plate 2 on the same side are located at the end of the connection end of each pile body 1.

[0043] When the two pile bodies 1 need to be installed together, the upper pile body 1 is hoisted to the top of the lower pile body 1 by the hoisting equipment, and when the two end plates 2 are brought into contact, the lower connecting bolt 48 can be used to fasten the end of the lower set of pipe clamps 45 away from the threaded rod 41 through the mounting frame 47. Then, after rotating the upper set of pipe clamps 45 to fit against the outer surface of the upper pile body 1, the mounting frame 47 is rotated to cover the end of the upper set of pipe clamps 45 away from the threaded rod 41. After the upper set of pipe clamps 45 is fastened by the upper connecting bolt 48, the two sets of pipe clamps 45 can be aligned with the pile bodies 1 that need to be connected.

[0044] Once the two pile bodies 1 and the end plate 2 of the connecting end are accurately aligned, the four sets of support bolts 33 passing through the connecting ring 32 and the end plate 2, as well as the installation bolts 46 passing through the connecting ring 32, the pipe clamp 45, and the end plate 2, are tightened to complete the connection and installation of the two pile bodies 1 and the end plate 2.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
