Description

Technical Field

[0001] This utility model belongs to the field of steel pipe pile splicing technology, and in particular relates to a mold for splicing and extending CO steel pipe piles. Background Technology

[0002] The G110 Dengkou Yellow River Bridge project requires 29m long steel pipe piles as the main body to form a cofferdam for the substructure construction of pier #29. However, the common length of steel pipe piles is 12m or 16m. Due to transportation cost constraints, the single length of steel pipe piles transported is generally no more than 18m. Therefore, it is necessary to transport steel pipe piles with a single length of no more than 18m first, and then perform on-site butt welding to extend them.

[0003] The conventional method is to select a flat and solid site for the butt joint operation and then weld the extension. However, due to the long length of the steel pipe piles used and the presence of "CO" connecting pipes on the steel pipe piles, the butt joint process is slow and the straightness of the butt joint cannot be guaranteed. Therefore, we provide a mold for butt joint extension of CO steel pipe piles to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for splicing CO steel pipe piles. The CO steel pipe is placed on the second positioning plate and fixed by a lifting device. Then, the two steel pipes are spliced ​​on the assembly platform. The misalignment position is finely adjusted. After the steel pipes are spliced, the splicing position is welded to extend the length. This solves the quality problems of slow splicing efficiency and lack of straightness in existing splicing methods.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a mold for butt jointing of CO steel pipe piles, including several mold mechanisms. Each mold mechanism is installed on the construction ground, and the distance between any two adjacent mold mechanisms is greater than 5m.

[0008] The present invention is further configured such that a second limiting plate is fixedly provided at the bottom of the L-shaped connecting plate, a second connecting hole corresponding to the first connecting hole is provided on one side of the second limiting plate, the first connecting hole and the corresponding second connecting hole are connected by a connecting chain, the connecting tube is sleeved inside the connecting assembly, and a sliding groove is provided at the top of the second positioning plate.

[0009] The present invention is further configured such that two T-shaped plates are slidably disposed on the top of the second positioning plate, the two T-shaped plates are symmetrically disposed on both sides of the steel pipe, a slider is fixedly disposed on the bottom of the T-shaped plate, the slider is slidably engaged with the corresponding groove, a clamping plate is fixedly disposed on the top of the T-shaped plate, the steel pipe is installed between the two clamping plates, and the clamping plate is connected to the corresponding L-shaped connecting plate by an elastic reset member.

[0025] Specifically, several connecting components 7 are installed on the sides of the connecting pipe 5. Adjacent connecting pipes 5 are connected by connecting components 7. The connecting component 7 includes a first positioning plate 8, which is installed at the bottom of the connecting pipe 5. Two first limiting plates 9 are fixedly installed on the top of the first positioning plate 8. Several first connecting holes 10 are opened on one side of the first limiting plate 9. The connecting pipe 5 is inserted between the two first limiting plates 9.

[0026] The operation process of this embodiment is as follows: each fixed pile 3 is installed on the construction ground, then the connecting pipe 5 is inserted into the corresponding limiting port 4, then the two adjacent connecting pipes 5 are connected by the connecting component 7, then the steel pipe 6 is placed on the connecting pipe 5 and fixed by the lifting equipment, then the two steel pipes 6 are joined on the assembly platform, the misalignment position is finely adjusted, and after the steel pipes 6 are joined, the joint position can be welded and extended.

[0027] In a second specific embodiment, based on the first specific embodiment, the connecting component 7 further includes a second positioning plate 11. The second positioning plate 11 is installed on the top of the connecting pipe 5, and L-shaped connecting plates 12 are symmetrically fixed on both sides of the second positioning plate 11. The L-shaped connecting plates 12 are installed on both sides of the connecting pipe 5.

[0028] Specifically, a second limiting plate 13 is fixedly installed at the bottom of the L-shaped connecting plate 12. A second connecting hole 14 corresponding to the first connecting hole 10 is opened on one side of the second limiting plate 13. The first connecting hole 10 and the corresponding second connecting hole 14 are connected by a connecting chain 15. The connecting tube 5 is sleeved inside the connecting assembly 7. A sliding groove 16 is opened at the top of the second positioning plate 11.

[0029] Furthermore, two T-shaped plates 17 are slidably arranged on the top of the second positioning plate 11. The two T-shaped plates 17 are symmetrically arranged on both sides of the steel pipe 6. A slider is fixedly arranged at the bottom of the T-shaped plate 17.

The first limiting plate 9 and the second limiting plate 13 are connected in the corresponding second connecting hole 10, so that the positions of the first positioning plate 8 and the second positioning plate 11 are fixed. Then, the steel pipe 6 is placed on the top of the corresponding second positioning plate 11. During the insertion of the steel pipe 6, the two clamping plates 18 are squeezed, causing the two clamping plates 18 to move away from each other. The two T-shaped plates 17 move away from each other, and the elastic reset member 19 is compressed. When the steel pipe 6 is in contact with the top of the second positioning plate 11, the two clamping plates 18 clamp the steel pipe 6, so that the steel pipe 6 is fixed.
