[0002] Steel pipe pile construction is a critical task in bridge construction, and the fishing method is widely used due to its efficiency. After the two steel pipe piles are constructed, the crown beam must be constructed above them. The crown beam is connected to the steel pipe piles by welding mounting brackets to the steel pipe piles, then accurately placing the crown beam on the mounting brackets and securing them by welding. This step requires high precision and is difficult to perform, necessitating a stable and convenient steel pipe pile connection platform.

[0003] Among existing construction methods, a common approach is to weld a working platform directly onto steel pipe piles. However, while this method is simple and easy to implement, it is extremely difficult to remove the platform after construction is completed and can easily damage the steel pipe piles, affecting their structural integrity and service life.

[0004] To prevent damage to the steel pipe piles, existing techniques employ a top support structure to place a work platform around the piles. This structure effectively provides a working space and facilitates welding operations. However, this integrated structure creates a significant obstruction above the steel pipe piles after the crown beam is constructed, preventing the construction platform from being removed by hoisting upwards, making removal difficult.

[0005] Based on this, it is necessary to study a steel pipe pile connection platform. Utility Model Content

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0029] Example 1. This example aims to provide a steel pipe pile connection platform, which is mainly used for the docking and fixation of steel pipe piles and crown beams during bridge construction. In view of the problems that the existing steel pipe pile construction platform is troublesome to install and difficult to disassemble and assemble, this example provides a combined steel pipe pile connection platform.

[0030] like Figure 1 As shown in the figure, a steel pipe pile connection platform includes a first platform 5, a second platform 6 and a docking assembly; the first platform 5 and the second platform 6 are both semi-annular structures, and a hollow annular pile connection platform is formed by the docking assembly; in terms of the implementation structure, the first platform 5 and the second platform 6 can be combined to form a hollow annular structure, which can be disassembled from both sides outward. Before the construction of the crown beam, the annular platform is assembled on site and arranged around the steel pipe pile in a hoisting manner. When dismantling, the docking assembly is removed to complete the disassembly. The operation process is simple, which greatly improves the dismantling efficiency.

[0031] In the specific structure, the first platform 5 and the second platform 6 each include a support ring 11, a support base 9, a support rod 12, a reinforcement base 13, a fastening rod 16, a fence, and a base plate. The support ring 11 has a semi-annular structure and can be specifically made of a bent ring of steel, which forms a support structure from the inside. The support base 9 is fixed to the bottom of the support ring 11. The support base 9 and the support ring 11 can be fixed in the following manner. In this embodiment, a mounting groove 10 is provided on the inner side of the support base 9. The support ring 11 is adapted to be seated in the mounting groove 10 and fixed by bolts.

[0032] The support seat 9 has a support rod 12 extending outward, and a slide groove is provided at the bottom of the support seat 9. The reinforcement seat 13 is slidably mounted in the slide groove, and a reinforcement plate 18 is provided on the inner side of the reinforcement seat 13; in the specific structure, the slide groove is a dovetail groove structure, and a dovetail-shaped slide seat is provided on the reinforcement seat 13. The two cooperate to achieve sliding and prevent the reinforcement seat 13 from falling out. At the same time, this embodiment exposes the lower area of ​​the reinforcement seat 13, and a reinforcement plate 19 is provided between the end of the slide seat and the end of the reinforcement seat 13, thereby improving the support strength of the reinforcement seat 13.

[0033] A fastening seat 17 is provided at the bottom of the support rod 12, and the fastening rod 16 is threadedly connected to the fastening seat 17, and its inner end is against the outer side of the reinforcement seat 13, so that the reinforcement seat 13 can move inward; in the specific structure, a top seat 14 is provided at the outer end of the sliding seat, and a top groove is provided on the top seat 14, and the fastening seat 17 is sleeved in the top groove. During implementation, a top block 15 can be provided at the end of the fastening seat 17, and by screwing the fastening rod 16 from the outer end, a locking force can be provided, thereby pushing the slider to move inward, so that the reinforcement plate 18 is tightly attached to the surface of the steel pipe pile. In order to increase the friction between the reinforcement plate 18 and the steel pipe pile, the reinforcement plate 18 can be a rubber structure, and the rubber structure can adapt to the surface of the steel pipe pile as it deforms to increase the friction area.

[0034] The enclosure is at the outer end of the support rod 12, and the base plate is laid on the upper area of ​​the support rod 12 to form a construction platform; in the specific implementation structure, the enclosure includes an enclosure seat, an enclosure body 20 and an inner rod 21. The enclosure seat is a semi-annular structure, and a limit is formed at the outer end to fix the enclosure seat to the outer end of the support rod 12, thereby improving the overall structural strength. The specific fixing method can be to provide a mounting plate at the lower part of the enclosure seat, and the mounting plate is fixed to the end of the support rod 12.

[0035] In this embodiment, the inner rod is fixed to the upper part of the enclosure seat, and the enclosure body 20 is sleeved on the inner rod 21. A docking plate is provided on the enclosure body. During implementation, the inner rod serves as a supporting body, and a connecting plate is provided at the bottom thereof. The connecting plate is fixed on the annular enclosure seat, and the enclosure body can be further removed from the enclosure seat, thereby reducing the difficulty of dismantling in a dispersed manner.

[0036] The docking assembly includes a docking plate 7 and a docking bolt. The docking plate 7 is arranged on both sides of the support ring 11, and corresponding docking holes 8 are provided on the docking plate. The docking bolts are connected therein, so that the two half rings are docked to form an annular platform. In order to facilitate docking, this embodiment provides a frustum-shaped connecting hole 22 on the docking plate on one side, and a connecting block is provided on the docking plate on the opposite side, which can be adapted to be inserted into the connecting hole.

[0037] During the installation process, before the crown beam is constructed, the first platform 5 and the second platform 6 are combined into an annular platform on the ground, and the fastening rod 16 is adjusted so that the area formed by the reinforcement plate 18 is larger than the steel pipe pile 1. The annular platform is then lowered by hoisting. During this assembly process, the enclosure structure, base plate, support ring 11 and support seat 9 are hoisted into place and assembled in batches as needed to reduce the weight of a single transport. After hoisting into place, the fastening rod 16 is driven to screw the fastening rod 16 forward, tightening the reinforcement plate 18 against the surface of the steel pipe pile 1, completing the assembly of the annular platform. The mounting seat 2 is then constructed on the upper part of the steel pipe pile, and the crown beam 3 is hoisted to the construction site and assembled by welding. After welding is completed, the construction platform is dismantled. During dismantling, the embodiment only needs to separate the docking assembly. Since the two halves are both semi-annular structures, they can move freely to both sides after the docking assembly is separated. Then, the hoisting and separation can be carried out simultaneously.

[0038] Therefore, this embodiment is assembled in a way of enclosing both sides, and a combined docking structure is used to form a construction platform. It is simple to operate and convenient to construct. There is no need to consider the obstruction of the upper part of the steel pipe pile, which facilitates the dismantling of the working platform. The device can be used repeatedly, saving costs and providing convenience for people.

[0039] The above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is to interlock and connect the two semi-annular structures from both sides of the steel pipe pile during construction. After the connection is completed, the construction platform is fixed by a fastening structure. The structure is easy to disassemble and construct, and the combined structure is simple to operate. There is no need to consider whether there is an obstruction on the upper part of the steel pipe pile, which provides convenience for the combined docking of the steel pipe pile and the crown beam. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
