Description

Technical Field

[0001] This utility model relates to the field of pipe pile connection structure technology, and more specifically, to a pipe pile connection structure for high-strength buildings. Background Technology

[0002] In modern construction, high-strength pipe piles serve as an important supporting component of infrastructure. The stability and durability of their connection structure are crucial. Pipe piles on the market are generally equipped with corresponding metal ring structures at both ends. During specific installation operations, flange connections are made through the flanges on the metal rings to complete the fixing operation.

[0003] However, since flange connections also use bolts for fixing, when multiple bolts are used to fix the upper and lower pipe piles, all the axial force on the pipe piles acts on the bolts. The lack of corresponding insertion and limiting fittings between the upper and lower pipe piles causes all the axial force to act on the bolts, easily leading to bolt damage and hindering a stable connection. Therefore, we propose a high-strength pipe pile connection structure for buildings. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength pipe pile connection structure for buildings, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength building pipe pile connection structure includes a lower pipe pile, a rigid insertion ring fixedly installed at the bottom end of the lower pipe pile, an upper pipe pile arranged above the lower pipe pile, and end insertion rings fixedly installed at the top ends of both the lower and upper pipe piles. Multiple insertion positioning grooves arranged in annular intervals are provided on the inner wall of the end insertion rings. A first flange is fixedly installed on the annular side of the end insertion ring. An inner insertion ring is fixedly installed at the bottom end of the upper pipe pile, and the inner insertion ring and the end insertion ring are interlocked. Multiple inclined positioning protrusions arranged in annular intervals are fixedly installed on the annular side of the inner insertion ring, and the inclined positioning protrusions are interlocked with the insertion positioning grooves. A second flange is fixedly installed at the bottom end of the upper pipe pile, and the second flange is fixedly connected to the first flange below it by multiple fastening bolts.

[0007] Preferably, a plurality of first pressure-resistant plates arranged in a ring at equal intervals are fixedly installed between the first flange and the end plug ring, and the cross-section of the first pressure-resistant plate is triangular.

[0008] Preferably, a plurality of second pressure-resistant plates arranged in a ring at equal intervals are fixedly installed between the upper pipe pile and the second flange, and the number of the second pressure-resistant plates is 4 to 12.

[0009] Preferably, the size of the inner insertion ring is adapted to the size of the end insertion ring, and the size of the inclined positioning protrusion is adapted to the size of the insertion positioning groove.

[0010] Preferably, the cross-sections of the inclined positioning protrusion and the insertion positioning groove are both isosceles trapezoidal in shape, and the inner diameter of the insertion positioning groove decreases sequentially from top to bottom.

[0011] Preferably, both the lower pipe pile and the upper pipe pile are provided with multiple inner rigid reinforcing rings, and the inner rigid reinforcing rings are annular.

[0012] Preferably, the plurality of inner rigid reinforcing rings are arranged linearly at equal intervals along the vertical direction, and the lower pipe pile and the upper pipe pile are each provided with a plurality of vertical inner support rods arranged in a ring at equal intervals.

[0013] Preferably, the vertical inner support rod is arranged vertically, and the inner rigid reinforcing ring and the vertical inner support rod are integrally formed with the corresponding lower pipe pile and upper pipe pile.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses multiple fastening bolts to fix the first flange and the second flange together, which facilitates the fixing operation. With the set insertion positioning groove and inclined positioning protrusion, the inclined positioning protrusion can limit the operation between the lower pipe pile and the upper pipe pile after being inserted into the insertion positioning groove. This makes the axial force between the lower pipe pile and the upper pipe pile act on the inclined positioning protrusion, thereby avoiding damage to the bolt part and achieving a stable connection effect.

[0016] 2. By setting the first and second pressure-resistant plates, this utility model can provide pressure-resistant support for the first and second flange portions, making the structure of the first and second flange portions more robust and stable. Attached Figure Description

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.

[0029] Please see Figures 1-4 This utility model provides a technical solution: a high-strength building pipe pile connection structure, including a lower pipe pile 1, a rigid insertion ring 4 fixedly installed at the bottom end of the lower pipe pile 1, an upper pipe pile 2 arranged above the lower pipe pile 1, and end insertion rings 3 fixedly installed at the top ends of both the lower pipe pile 1 and the upper pipe pile 2. Multiple insertion positioning grooves 32 arranged in annular and equidistant patterns are provided on the inner wall of the end insertion ring 3. A first flange 30 is fixedly installed on the annular side of the end of the end insertion ring 3. An inner insertion ring 5 is fixedly installed at the bottom end of the upper pipe pile 2. The inner insertion ring 5 and the end insertion ring 3 are inserted into each other. Multiple inclined positioning protrusions 50 arranged in annular and equidistant patterns are fixedly installed on the annular side of the inner insertion ring 5. The inclined positioning protrusions 50 and the insertion positioning grooves 32 are inserted into each other, thereby achieving the operation of supporting the axial force between the upper pipe pile 2 and the lower pipe pile 1 by inserting the inclined positioning protrusions 50 into the insertion positioning grooves 32, making the structure between the upper pipe pile 2 and the lower pipe pile 1 more robust and stable.

[0030] Specifically, a second flange 51 is fixedly installed at the bottom of the upper pipe pile 2. The second flange 51 is fixedly connected to the first flange 30 below by multiple fastening bolts, which facilitates the fixed connection operation.

[0031] In this embodiment, a plurality of first pressure-resistant plates 31 arranged in a ring at equal intervals are fixedly installed between the first flange 30 and the end plug ring 3. The cross-section of the first pressure-resistant plate 31 is triangular. A plurality of second pressure-resistant plates 52 arranged in a ring at equal intervals are fixedly installed between the upper pipe pile 2 and the second flange 51. The number of second pressure-resistant plates 52 is 4 to 12, which serve to provide pressure-resistant support for the first flange 30 and the second flange 51.

[0032] Specifically, the size of the inner insertion ring 5 is adapted to the size of the end insertion ring 3, and the size of the inclined positioning protrusion 50 is adapted to the size of the insertion positioning groove 32, which is used to stabilize the insertion and mating operation.

[0033] Furthermore, the cross-sections of the inclined positioning protrusion 50 and the insertion positioning groove 32 are both isosceles trapezoidal in shape, and the inner diameter of the insertion positioning groove 32 decreases from top to bottom, making it easier for the inclined positioning protrusion 50 to be inserted into the insertion positioning groove 32.

[0034] In addition, both the lower pipe pile 1 and the upper pipe pile 2 are equipped with multiple inner rigid reinforcing rings 6. The inner rigid reinforcing rings 6 are ring-shaped and arranged linearly and equally spaced along the vertical direction. Both the lower pipe pile 1 and the upper pipe pile 2 are equipped with multiple vertical inner struts 60 arranged in a ring shape and equally spaced. The vertical inner struts 60 are vertically positioned. The inner rigid reinforcing rings 6 and the vertical inner struts 60 are integrally formed with the corresponding lower pipe pile 1 and upper pipe pile 2, ensuring that the structure of the lower pipe pile 1 and the upper pipe pile 2 is more solid and stable, and improving the overall stability of the structure.

[0035] When using the high-strength building pipe pile connection structure of this utility model, the lower pipe pile 1 is inserted into the soil base, then the inner insertion ring 5 is inserted into the end insertion ring 3, and at the same time the inclined positioning protrusion 50 is inserted into the insertion positioning groove 32. Then, the upper second flange 51 and the lower first flange 30 are fixed together with multiple fastening bolts to complete the fixing operation.
