Description

Technical Field

[0001] The utility model relates to the technical field of connection between a foundation and a prestressed high-strength concrete pipe pile, in particular to an adjustable fully welded pile guide hoop device. Background Art

[0002] In the prior art, for the connection of traditional statically pressed prestressed high-strength concrete pipe piles, a guide hoop is usually installed on the lower section of the pile, and the upper section of the pile is aligned in place and then spot welded symmetrically. After the upper and lower sections of the pile are fixed, the guide hoop is removed and the welding is performed in layers. This method is not easy to operate during welding and is time-consuming and labor-intensive. When connecting the piles, the guide hoop can only be fully welded after the spot welding is completed and the guide hoop is removed. In addition, the verticality requirements of prestressed pipe piles are high. There are situations where multiple prefabricated piles are constructed at the same time on site, and it is very likely that the spot welding is not in place. At the same time, the residual deformation of the weld causes the misalignment deviation of the upper and lower sections of the pipe pile to be greater than the specification requirements, which brings great difficulties to the construction workers.

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 5As shown, the present embodiment provides an adjustable full-welded pile guide hoop device, comprising a guide hoop, a lower guide hoop 6, a connecting plate 10 and a support leg, the upper guide hoop 1 and the lower guide hoop 6 are respectively fixed at the upper and lower ends of the connecting plate 10, and the connecting plate 10 is located outside the cavity of the upper guide hoop 1 and the lower guide hoop 6, the lower guide hoop 6 is used to be sleeved on the lower section of the pile body, the upper section of the pile body is connected to the lower section of the pile body by inserting the upper guide hoop 1 from top to bottom, the top end of the support leg is connected to the connecting plate 10, and the bottom end of the support leg is used to support on the ground.

[0024] The connecting plate 10 connects the upper guide hoop 1 with the lower guide hoop 6. When the pile is fully welded, the lower guide hoop 6 is first put on the lower section of the pile body, and then the overall position of the upper guide hoop 1 and the lower guide hoop 6 is adjusted by holding the supporting legs, and the height of the upper guide hoop 1 is made greater than the height of the lower section of the pile body, and then the supporting legs are supported on the opposite surface to stabilize the upper guide hoop 1 and the lower guide hoop 6.

[0025] Then insert the upper pile body from the top of the upper guide hoop 1 and connect it with the top of the lower pile body, and then weld all positions except the connecting plate 10. After welding is completed, use the legs to rotate the upper guide hoop 1 and the lower guide hoop 6, so that the connecting plate 10 is displaced in the circumferential direction and the position that was not welded for the first time is exposed, and then directly weld, and the overall construction is completed after the welding is completed and the pile is pressed.

[0026] Among them, one side of the upper guide hoop 1 and the lower guide hoop 6 is open, and buckles 3 are installed on both sides of the opening, and a bolt 5 is inserted between the two buckles 3. The threaded end of the bolt 5 passes through the two buckles 3 and then connects with the nut 4. When the upper guide hoop 1 is initially put on the lower pile body, the upper pile body passes through the upper guide hoop 1 to connect with the lower pile body, and after the first welding is completed, the position of the connecting plate 10 is adjusted by rotating the upper guide hoop 1 and the lower guide hoop 6, and the bolt 5 and the nut 4 can be rotated to loosen the upper guide hoop 1 and the lower guide hoop 6. In the welding process, the upper guide hoop 1 and the lower guide hoop 6 are locked and fixed by the cooperation of the bolt 5 and the nut 4 to ensure the stability of the upper and lower pile bodies during the welding operation and improve the welding effect.

[0027] The top of the leg is rotatably mounted on the outer side of the connecting plate 10 so that the leg can swing 180° in the longitudinal plane. The top of the leg is connected to the connecting plate 10 through a bearing 9, and a conical foot 7 is provided at the bottom of the leg. The conical foot 7 is inserted into the ground to improve the stability of the upper guide hoop 1 and the lower guide hoop 6, and at the same time improve the welding effect.
