Description

Technical Field

[0001] This utility model relates to the field of prestressed square pile construction, specifically a support device for erecting reinforcing bars in prestressed square pile cores. Background Technology

[0002] After drilling, prestressed square piles need to be filled with concrete. Before pouring, reinforcing bars need to be placed in the pile hole. To prevent the reinforcing bars from sinking during concrete pouring, multiple transverse support bars are usually installed at the top of the square pile. These support bars are welded to the reinforcing bars to provide support and prevent sinking, thus ensuring the quality of the pile. However, after the concrete is poured, the presence of the support bars at the top of the square pile can cause uneven concrete surfaces. Furthermore, during waterproofing, the support bars need to be removed to level the pile head. Removing the support bars requires chiseling and cutting the welded joints, making the subsequent leveling and repair of the pile head more complicated and increasing the leveling cost. This results in the high difficulty and cost of the existing structure for supporting the reinforcing bars in the later stages of square pile processing. Utility Model Content

[0003] The purpose of this utility model is to provide a support device for the erection of core reinforcement in prestressed square piles. It can solve the technical problem that the existing support structure for core reinforcement increases the difficulty and cost of subsequent pile head leveling, ensures effective support for the core reinforcement, and facilitates separation from the pile head, thereby reducing the difficulty and cost of subsequent pile head leveling and improving the convenience of actual use of the support structure.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A support device for erecting reinforcing bars in prestressed square piles includes a support base plate set on the top of the pile body, multiple reinforcing bars in the pile body, and supporting reinforcing bars between the multiple reinforcing bars. Multiple supporting rods are provided on the support base plate, and a supporting top plate is provided on each supporting rod. The supporting reinforcing bars are in contact with the top of the supporting top plate. The support base plate and the supporting top plate are symmetrically arranged in pairs. Both the support base plate and the supporting top plate have arc-shaped holes on their sides. The structure formed by the arc-shaped holes on both sides is fitted onto the outside of the multiple reinforcing bars. A locking buckle is provided between the two supporting top plates.

[0006] Furthermore, the support top plate is provided with multiple through holes, the support rod passes through the through holes and is slidably connected to them, the support rod is provided with multiple support blocks, and the support blocks are in contact with the bottom of the support top plate.

[0007] Furthermore, the support block is a nut, which is threaded onto the support rod.

[0008] Furthermore, a protective sleeve is threadedly connected to the top of the support rod above the support top plate, and a sealing ring is provided between the protective sleeve and the support top plate.

[0009] Furthermore, the locking buckle includes a locking block and a locking tongue, which are respectively disposed on the support top plates on both sides. The locking tongue is provided with a locking hole, which is movably inserted into the locking block.

[0010] Furthermore, a locking rod is rotatably connected to one side of the supporting top plate, and the locking tongue is rotatably connected to the locking rod.

[0011] Furthermore, the bottom of the support rod is provided with a conical seat, which is fixedly connected to the support base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model is achieved by setting a support base plate on the top of the pile body, setting multiple support rods on the support base plate, and setting a support top plate on the support rods. The support steel bars connected to the core steel bars are in contact with the top of the support top plate. This structure achieves effective support for the support steel bars, avoids the sinking of the core steel bars during concrete pouring, and ensures the quality of prestressed square pile construction. Moreover, the support base plate is placed on the top of the pile body, and the support base plate can be removed after the concrete is poured. The support steel bars are left in the raft slab above the pile body. Without the influence of the support steel bars, the concrete surface at the top of the pile body is smoother. Excess concrete can be knocked off from the support base plate, making the later leveling operation of the pile head faster and more convenient, and greatly reducing the difficulty and cost of later leveling.

[0014] 2. The top and bottom support plates are symmetrically arranged in pairs. Both the top and bottom support plates have arc-shaped holes on their sides. The structure formed by the arc-shaped holes on both sides is fitted onto the outside of the core reinforcement. There are locking buckles between the top and bottom support plates on both sides. This structure allows the top and bottom support plates on both sides to be connected together by locking buckles. When in use, the arc-shaped holes on both sides can ensure the accuracy of concrete pouring from this point. When disassembling, simply open the locking buckles and pull the top and bottom support plates to both sides. This makes the use and disassembly of the support structure very convenient. It can also be cleaned and reused, further improving the convenience of disassembly and use of the support structure and reducing the overall use cost. Attached Figure Description

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0022] Reference Figure 1 and Figure 2This utility model describes a support device for erecting reinforcing bars 3 in prestressed square piles. The main structure includes a support base plate 2 placed on top of the pile body 1. Multiple reinforcing bars 3 are installed inside the pile body 1, preferably extending vertically above the pile body 1. These reinforcing bars 3 are arranged in a circular array. Multiple annular reinforcing bars are installed inside the pile body 1 to connect the reinforcing bars 3. Supporting reinforcing bars 4 are provided between the reinforcing bars 3, located above the pile body 1 and extending laterally, connected to the reinforcing bars 3 by welding. Multiple supporting rods are fixed to the support base plate 2 by welding or integral forming. 5. A supporting top plate 6 is provided on the supporting rod 5. The supporting rod 5 is used to connect the supporting bottom plate 2 and the supporting top plate 6. The supporting steel bar 4 is in contact with the top of the supporting top plate 6. This structure uses the supporting bottom plate 2, supporting rod 5, and supporting top plate 6 to support the supporting steel bar 4. This allows the multiple core-filling steel bars 3 connected to the supporting steel bar 4 to be effectively supported by the supporting structure and the pile body 1. When concrete is poured into the pile body 1, the core-filling steel bars 3 will not sink, ensuring the quality of the prestressed square pile construction. Moreover, the supporting structure is placed on top of the pile body 1, so that the top of the pile body 1 does not directly contact the transverse supporting steel bar 4. When the concrete is poured to the top, the top concrete surface is not supported. The interference of the reinforcing steel bar 4 makes the surface smoother. The upper reinforcing steel bar 4 is connected to the core-filling steel bar 3 and left in the raft slab above the pile body 1. When leveling the top of the pile body 1 later, it is not necessary to cut the reinforcing steel bar 4. It is only necessary to knock off the excess concrete from the supporting base plate 2 to quickly level the top of the pile body 1. The subsequent leveling operation is faster and simpler, and the construction cost is lower. The supporting base plate 2 and the supporting top plate 6 are two symmetrically arranged. The sides of the supporting base plate 2 and the supporting top plate 6 are provided with arc holes 7. The structure formed by the arc holes 7 on both sides is sleeved on the outside of multiple core-filling steel bars 3. There are locking buckles between the two sides of the supporting top plate 6. This structure makes the support... Both the top support plate 6 and the bottom support plate 2 are composed of two parts, left and right. When in use, the two parts on the left and right sides are brought close together and connected and fixed by locking buckles, so that the two arc holes 7 form a circular hole that fits over the outside of the core-filled steel bar 3. Then, the assembled support structure is placed on top of the pile body 1 to support the supporting steel bar 4. When disassembly is required after use, the locking buckles are released, and the two parts of the bottom support plate 2 and the top support plate 6 are pulled to the sides, so that the bottom support plate 2 and the top support plate 6 can be easily removed from the top of the pile body 1 and the supporting steel bar 4. After cleaning, they can be reused, making the use and disassembly of the support structure more convenient, greatly improving construction efficiency and reducing the overall construction cost.

[0023] Preferably, the supporting top plate 6 is provided with multiple through holes 8, and the supporting rod 5 passes through the through holes 8 and is slidably connected to them. This structure allows the supporting top plate 6 to move up and down relative to the supporting rod 5, so that when supporting the supporting steel bar 4 and disassembling it later, the supporting top plate 6 can slide down to separate it from the supporting steel bar 4, making the later disassembly more convenient. The supporting rod 5 is provided with multiple supporting blocks, and the supporting blocks are in contact with the bottom of the supporting top plate 6. The setting of the supporting blocks can support and fix the supporting top plate 6 after it is adjusted to a designated position, ensuring the firmness of the supporting top plate 6 and improving the support effect.

[0024] Preferably, the support block is a nut 9, which is threaded onto the support rod 5. With this structure, the nut 9 can be rotated to adjust its vertical position under the action of the threaded connection, thereby increasing the height of the support top plate 6 in contact with it, making the adjustment of the height of the support top plate 6 more convenient and stable.

[0025] Preferred, refer to Figure 3 and Figure 4 A protective sleeve 10 is threadedly connected to the top of the support rod 5 above the support top plate 6. A sealing ring 11 is provided between the protective sleeve 10 and the support top plate 6. The protective sleeve 10 can be fixed to the top of the support rod 5 by means of threaded connection, so that concrete will not stick to the top of the support rod 5 when concrete is poured, thereby making the subsequent vertical sliding adjustment of the support top plate 6 along the support rod 5 smoother.

[0026] Preferably, the locking buckle includes a locking block 12 and a locking tongue 13. The locking block 12 and the locking tongue 13 are respectively disposed on the supporting top plates 6 on both sides. The locking block 12 is fixed to the top of the supporting top plate 6 by welding or bolts. The locking tongue 13 is provided with a locking hole 14. The locking hole 14 is movably inserted into the locking block 12. When the supporting top plates 6 on both sides are brought close to each other, the locking hole 14 of the locking tongue 13 is movably inserted into the outside of the locking block 12, thereby connecting the supporting top plates 6 on both sides into one piece in the lateral direction. The structure is simple and the disassembly and assembly are more efficient and convenient.

[0027] Preferably, a locking rod 15 is rotatably connected to the supporting top plate 6 on one side via a pin or hinge, and the locking tongue 13 is rotatably connected to the locking rod 15 via a pin or hinge. With this structure, the locking rod 15 only needs to be rotated toward the locking block 12 to move the locking tongue 13 on the locking rod 15 toward the locking block 12. After the locking hole 14 on the locking tongue 13 is inserted and sleeved on the outside of the locking block 12, the locking rod 15 is rotated in the opposite direction, thereby achieving the connection between the locking tongue 13 and the locking block 12 in the lateral direction, further simplifying the convenience of the locking tongue 13 and the locking block 12.

[0028] Preferably, the bottom of the support rod 5 is fixed with a conical seat 16 by welding or integral molding. The conical seat 16 has a structure that is wider at the top and narrower at the bottom. The conical seat 16 is fixedly connected to the support base plate 2 by welding or integral molding. This structure makes the connection area between the bottom of the support rod 5 and the support base plate 2 larger, thereby providing more stable support for the support rod 5 and improving the structural strength of the support rod 5.

[0029] Working Principle: The structure of this utility model features a supporting base plate 2 at the top of the pile body 1, multiple supporting rods 5 on the supporting base plate 2, and a supporting top plate 6 on the supporting rods 5. Supporting reinforcing bars 4, connected to the core-filling reinforcing bars 3, contact the top of the supporting top plate 6. This structure effectively supports the supporting reinforcing bars 4, preventing the core-filling reinforcing bars 3 from sinking during concrete pouring, thus ensuring the quality of prestressed square pile construction. Furthermore, the supporting base plate 2, placed at the top of the pile body 1, can be removed after concrete pouring. The supporting reinforcing bars 4 remain within the raft slab above the pile body 1. Without the influence of the supporting reinforcing bars 4, the concrete surface at the top of the pile body 1 is smoother. Excess concrete can be easily removed from the supporting base plate 2, making subsequent leveling operations at the pile head faster and more convenient. The design is convenient, greatly reducing the difficulty and cost of subsequent leveling. The top support plate 6 and bottom support plate 2 are symmetrically arranged, with arc-shaped holes 7 on their sides. The structure formed by the arc-shaped holes 7 on both sides is fitted onto the outside of the core-filling steel reinforcement 3. Locking buckles are provided between the top support plates 6 on both sides. This structure allows the top support plates 6 and bottom support plates 2 on both sides to be connected together via locking buckles. During use, the arc-shaped holes 7 on both sides ensure the accuracy of concrete pouring from this point. Disassembly only requires opening the locking buckles and pulling the top support plate 6 and bottom support plate 2 to both sides, making the use and disassembly of the support structure very convenient. It can also be cleaned and reused, further improving the convenience of disassembly and use of the support structure and reducing the overall cost of use.
