Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile technology, specifically a recyclable temporary steel bridge steel pipe pile horizontal connection device. Background Technology

[0002] In the construction of cast-in-place piles on water, temporary steel bridges are often erected as transportation and pile construction platforms for ease of construction. Using small-diameter steel pipe piles is problematic because underwater horizontal bracing is not feasible, and the excessive length of the piles leads to insufficient horizontal resistance of the overall bridge / platform. Using large-diameter steel pipe piles can address the horizontal resistance issue and improve the overall stability of the waterborne steel platform, but this significantly increases steel costs. Therefore, to improve the horizontal resistance and overall stability of temporary steel bridges on water, horizontal bracing devices are often added between the steel pipe piles. Existing horizontal bracing devices primarily connect the steel pipe piles through welding. Once welded, the position of the bracing cannot be changed, and its removal damages the welded joints, weakening the pile's strength after recycling. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a recyclable temporary steel bridge steel pipe pile horizontal connection device, which solves the problems mentioned in the background.

[0004] This utility model provides the following technical solution: a recyclable temporary steel bridge steel pipe pile horizontal connection device, comprising: a steel pipe foundation pile, wherein a limiting structure is sleeved on the outer wall of the steel pipe foundation pile, and a horizontal connection device is sleeved on the outer wall of the steel pipe foundation pile.

[0005] Preferably, the limiting structure includes a semi-circular limiting clamp, the outer wall of which is fixedly connected to a clamp extension plate, the inner wall of which is fitted with a limiting anchor bearing, the outer wall of which is threadedly connected to a limiting anchor bolt, and the inner wall of which is provided with a limiting anchor hole.

[0006] Preferably, the semi-circular limiting clamp is configured as a semi-circle, and the size of the inner wall of the semi-circular limiting clamp is adapted to the size of the outer wall of the steel pipe pile.

[0007] Preferably, the horizontal coupling device includes a horizontal coupling end clamp structure, the inner wall of the horizontal coupling end clamp structure is sleeved with a horizontal coupling structure, and the outer wall of the horizontal coupling end clamp structure is connected to an anchoring structure.

[0008] Preferably, the flat-connection end clamp structure includes a semi-circular end clamp, the outer wall of the semi-circular end clamp is connected to a clamp extension reinforcing plate, and the outer wall of the clamp extension reinforcing plate is connected to a clamp flat-connection end.

[0009] Preferably, the horizontal coupling structure includes a horizontal coupling end joint, and the outer wall of the horizontal coupling end joint is connected to a horizontal coupling rod.

[0010] Preferably, the anchoring structure includes a flat anchoring bearing, the outer wall of which is threadedly connected with a flat anchoring bolt, and the outer wall of the anchoring structure has a flat anchoring hole.

[0011] Preferably, the number of the flat-end joints is six, and one of every two flat-end joints is connected to a flat-end member.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This recyclable temporary steel bridge steel pipe pile horizontal connection device, by setting a limiting structure, allows each pair of semi-circular limiting clamps on the device to form a ring that fits onto the outer wall of the steel pipe pile. The limiting anchor bearing passes through the inner wall of the limiting anchor hole and is connected by a limiting anchor bolt. This allows the limiting structure on the device to connect the clamps on the upper and lower sides of the horizontal connection device, thereby enabling the limiting structure to limit the upper and lower parts of the steel pipe pile and increasing the overall stability of the horizontal connection device.

[0014] 2. The recyclable temporary steel bridge steel pipe pile horizontal coupling device, by setting up a horizontal coupling device structure, allows the horizontal coupling end clamp structure, horizontal coupling structure, and anchoring structure on the device to be sleeved on the outer wall of the steel pipe pile using the same threaded connection method as the limiting structure. The horizontal coupling structure cross-connects the horizontal coupling end clamp structures on both sides, thereby connecting the horizontal coupling devices on the device to play the function of improving horizontal resistance.

[0015] 3. The recyclable temporary steel bridge steel pipe pile horizontal connection device, by setting up structures such as limit anchor bearings, limit anchor bolts, horizontal connection anchor bearings, horizontal connection anchor bolts, and horizontal connection anchor holes, allows the limit structure and horizontal connection device on the device to be connected by threads. This allows the entire device to avoid the connection between steel pipe piles by welding, thus enabling the limit structure and horizontal connection device to achieve the characteristics of temporary installation and recycling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A recyclable temporary steel bridge steel pipe pile horizontal connection device includes: a steel pipe pile 1, a limiting structure 2 sleeved on the outer wall of the steel pipe pile 1, and a horizontal connection device 3 sleeved on the outer wall of the steel pipe pile 1.

[0024] The limiting structure 2 includes a semi-circular limiting clamp 21. The outer wall of the semi-circular limiting clamp 21 is fixedly connected to a clamp extension plate 22. The inner wall of the clamp extension plate 22 is fitted with a limiting anchor bearing 23. The outer wall of the limiting anchor bearing 23 is threadedly connected with a limiting anchor bolt 24. The inner wall of the clamp extension plate 22 has a limiting anchor hole 25. When the two semi-circular limiting clamps 21 on the device are symmetrically fitted onto the outer wall of the steel pipe pile 1, the limiting anchor bearings 23 on the device pass through the diameter of the limiting anchor hole 25, and the limiting anchor bolts 24 are threadedly connected and fixed from the limiting anchor bearings 23 on both sides. Thus, the two semi-circular limiting clamps 21 are fixedly connected at the overlapping point of the clamp extension plate 22, thereby enabling the limiting structure 2 to perform its limiting function at the upper and lower ends of the horizontal connection device 3.

[0025] The semi-circular limiting clamp 21 is set in a semi-circular shape, and the size of the inner wall of the semi-circular limiting clamp 21 is adapted to the size of the outer wall of the steel pipe pile 1. By adapting the size of the inner wall of the semi-circular limiting clamp 21 on the device to the size of the outer wall of the steel pipe pile 1, the limiting structure 2 on the device is fitted onto the outer wall of the steel pipe pile 1 based on the semi-circular limiting clamp 21.

[0026] The horizontal coupling device 3 includes a horizontal coupling end clamp structure 31, a horizontal coupling structure 32 sleeved on the inner wall of the horizontal coupling end clamp structure 31, and an anchoring structure 33 connected to the outer wall of the horizontal coupling end clamp structure 31. The four horizontal coupling end clamp structures 31 on the device are sleeved on the outer walls of the two steel pipe piles 1, and the anchoring structure 33 fixedly connected to the outer wall of the horizontal coupling end clamp structure 31 is connected to the horizontal coupling structure 32. The horizontal coupling structure 32 adopts a diagonal connection method, so that the two horizontal coupling structures 32 on the device connect the four horizontal coupling end clamp structures 31.

[0027] The horizontal coupling end clamp structure 31 includes a semi-circular end clamp 311, the outer wall of which is connected to a clamp extension reinforcing plate 312, and the outer wall of the clamp extension reinforcing plate 312 is connected to a clamp horizontal coupling connection end 313. The semi-circular end clamp 311 on the device is sleeved on the outer wall of the steel pipe pile 1, and the horizontal coupling anchoring hole 333 reserved in the clamp extension reinforcing plate 312 is used to connect with the horizontal coupling anchoring bearing 331. The number of horizontal coupling anchoring holes 333 opened on the top and side of the clamp horizontal coupling connection end 313 on the device is set according to the design requirements.

[0028] The horizontal coupling structure 32 includes a horizontal coupling end connector 321. The outer wall of the horizontal coupling end connector 321 is connected to a horizontal coupling rod 322. The horizontal coupling end connector 321 on the device is set as a solid rectangle, so that the top and side of the horizontal coupling end connector 321 are respectively opened, and the number of openings corresponds to the horizontal coupling anchor bearing 331 and corresponds to the horizontal and vertical opening positions of the clamp horizontal coupling connection end 313. The cross section of the horizontal coupling rod 322 can be set as I-shaped or rectangular according to requirements.

[0029] The anchoring structure 33 includes a horizontal anchoring bearing 331, and a horizontal anchoring bolt 332 is threadedly connected to the outer wall of the horizontal anchoring bearing 331. The outer wall of the anchoring structure 33 has a horizontal anchoring hole 333. The horizontal anchoring bearing 331 on the device has a circular cross section. The horizontal anchoring bearing 331 and the horizontal anchoring bolt 332 are installed through the horizontal anchoring hole 333 reserved on the clamp horizontal connection end 313 and the horizontal end joint 321, thereby connecting the horizontal devices to play the function of improving horizontal resistance.

[0030] The vertical horizontal anchor bearing 331 and horizontal anchor bolt 332, when installed together, can prevent the horizontal connecting rod 322 from moving vertically. When the vertical horizontal anchor bearing 331 and horizontal anchor bolt 332 are installed alone, the horizontal connecting rod 322 can move vertically. When the horizontal horizontal anchor bearing 331 and horizontal anchor bolt 332 are installed alone, the horizontal connecting rod 322 on the device can rotate vertically.

[0031] Among them, there are six horizontal coupling end joints 321, and one of every two horizontal coupling end joints 321 is connected to a horizontal coupling member 322. Through the six horizontal coupling end joints 321 on the device, when every two horizontal coupling end joints 321 on the device are fixed in the inner cavity of the clamp horizontal coupling connection end 313, one horizontal coupling end joint 321 is used to fix one horizontal coupling member 322, so that the horizontal coupling member 322 is connected at the diagonal position on the steel pipe pile 1 at the other end, thereby ensuring that the two intersecting horizontal coupling members 322 on the device do not overlap at the middle intersection, and the horizontal coupling member 322 stably plays a horizontal resistance role.

[0032] The working principle is as follows: First, steel pipe piles 1 are driven into the steel pipe piles 1 for the construction of the floating steel platform. Then, the horizontal resistance reinforcement position is determined on the driven steel pipe piles 1 according to the design requirements. At a certain distance above and below this position, upper and lower limiting structures 2 are installed respectively. Next, a horizontal coupling end clamp structure 31 is installed at the horizontal resistance reinforcement position. Then, the end joint of the horizontal coupling structure 32 is inserted into the horizontal coupling connection end 313 of the clamp. According to the construction progress and actual requirements, the corresponding horizontal coupling anchor bearings 331 and horizontal coupling anchor bolts 332 are inserted into the reserved holes for fixation, thus completing the installation of the horizontal coupling of the steel pipe pile 1. After the construction is completed, the anchor bolts, horizontal coupling anchor bolts 332, horizontal coupling anchor bearings 331, horizontal coupling structure 32, horizontal coupling end clamp structure 31 and upper limiting structure 2 are removed in sequence. Finally, the lower limiting structure 2 is removed, thus completing the recovery of the horizontal coupling device 3.

[0033] 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.
