They have advantages such as high bearing capacity, good bending resistance, stable and reliable quality, fast construction speed, and a clean and tidy construction site. They are widely used in the foundation engineering of various buildings and structures.

[0003] In building construction, prestressed concrete pipe piles are a commonly used type of foundation pile, and their connections typically employ flange connections. However, the nuts on existing prestressed concrete pipe pile flange connections are exposed to the external environment, making them susceptible to corrosion from rainwater and humid air, leading to rust. This affects the reliability and safety of the connection, and rusted nuts also increase the difficulty of disassembly and maintenance, causing inconvenience during construction. Therefore, this utility model proposes a prestressed concrete pipe pile connection flange. Utility Model Content

[0004] The purpose of this utility model is to address the problem in the background art where the nuts of prestressed pipe pile flange connections are exposed to the external environment and are easily corroded by rainwater, humid air, etc., leading to rusting of the nuts, which affects the reliability and safety of the connection. Rusty nuts also increase the difficulty of disassembly and maintenance, causing inconvenience to construction. Therefore, this utility model proposes a prestressed pipe pile connection flange.

The sealing cylinder is movably sleeved with the fixing post, and a pressing block is fixedly provided on the outer wall of the sealing cylinder. The pressing block is slidably connected to the guide groove.

[0007] Optionally, the guide assembly includes a guide rod fixedly disposed on the outer wall of the connecting pipe. The guide rod has grooves on both sides, and a second spring is disposed inside the groove. One end of the second spring is fixedly connected to the guide rod, and a slider is fixedly disposed on the other end of the second spring. The slider is slidably connected to the groove. A guide sleeve is movably sleeved on the outer wall of the guide rod. The guide sleeve is fixedly connected to the slider, and one end of the guide sleeve is fixedly connected to a fixed post.

[0008] Optionally, multiple reinforcing plates are fixedly disposed between the flanges, and the reinforcing plates are fixedly connected to the outer wall of the connecting pipe.

[0009] Optionally, the opposite sides of the flange are provided with a plurality of rubber gaskets.

[0010] Optionally, the outer wall of the pressing block is provided with anti-slip texture.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model uses the elastic force of the first spring to push the circular groove on the fixed column of the sealing cylinder to move to both sides, which can seal and cover the installed nuts and bolts, effectively preventing moisture, oxygen and other corrosive substances from contacting the nut surface, thereby slowing down or avoiding rusting of the nut and maintaining the reliability and stability of the connection.

[0013] Furthermore, by sliding the slider on the guide rod through the groove, and in conjunction with the second spring, the sealing assembly is stably guided to move horizontally. This allows the installation of bolts and nuts to occupy space, avoiding interference with nut clamping, thereby improving connection quality and efficiency. Attached Figure Description

[0028] like Figure 1 and Figure 2As shown, the prestressed pipe pile connecting flange proposed in this utility model includes: a connecting pipe 1, with flanges 2 fixedly installed at both ends of the connecting pipe 1, and the connecting pipe 1 and flanges 2 are welded together; multiple through holes 3 are provided on the flanges 2, and the multiple through holes 3 are arranged in annular and equidistant arrangement; multiple sets of sealing components 4 are arranged between the flanges 2 for sealing nuts, which can seal the nuts and improve service life; a guide component 5 is fixedly installed on the outer wall of the sealing component 4 for guiding its horizontal movement, and one end of the guide component 5 is fixedly connected to the connecting pipe 1 to increase the nut fastening space and improve the fastening efficiency.

[0029] like Figure 2 and Figure 3 As shown, the sealing assembly 4 includes a fixed post 41, with circular grooves 42 at both ends of the fixed post 41. A guide groove 43 is provided on the inner wall of the circular groove 42. A first spring 44 is provided inside the circular groove 42. One end of the first spring 44 is fixedly connected to the fixed post 41, and the other end of the first spring 44 is fixedly connected to a sealing cylinder 45, which can provide elastic force and reset the sealing cylinder 45. The sealing cylinder 45 is movably sleeved with the fixed post 41, which can guide the sealing cylinder 45 and make the movement of the sealing cylinder 45 more stable. A pressing block 46 is fixedly provided on the outer wall of the sealing cylinder 45. The pressing block 46 is slidably connected to the guide groove 43, which facilitates the movement of the sealing cylinder 45.

[0030] Furthermore, the guide assembly 5 includes a guide rod 51 fixedly disposed on the outer wall of the connecting pipe 1. The guide rod 51 has grooves 52 on both sides. A second spring 53 is disposed inside the grooves 52. One end of the second spring 53 is fixedly connected to the guide rod 51, and the other end of the second spring 53 is fixedly disposed on a slider 54, which can reset the slider 54. The slider 54 is slidably connected to the grooves 52. A guide sleeve block 55 is movably sleeved on the outer wall of the guide rod 51 to facilitate the guidance of the guide sleeve block 55 and make the guide sleeve block 55 move stably horizontally. The guide sleeve block 55 is fixedly connected to the slider 54, and one end of the guide sleeve block 55 is fixedly connected to the fixed post 41, thereby making the sealing assembly 4 move stably horizontally.

[0031] Secondly, multiple reinforcing plates 6 are fixedly installed between the flanges 2. The reinforcing plates 6 are fixedly connected to the outer wall of the connecting pipe 1 to increase the stability of the connection between the flanges 2 and the connecting pipe 1.

[0032] Furthermore, multiple rubber gaskets 7 are provided on the opposite side of the flange 2, and the rubber gaskets 7 are embedded in the through hole 3, which facilitates the improvement of the sealing performance of the sealing cylinder 45.

[0033] In addition, the outer wall of the pressing block 46 is provided with anti-slip texture 8, which can increase the friction of pressing and pulling, and improve the stability of pressing and pulling.

[0034] The working principle of this embodiment is as follows: the threaded through holes on the two prestressed pipe piles are placed opposite to the through holes 3 on the flange 2, and bolts are passed through the threaded through holes on the prestressed pipe piles and the through holes 3 on the flange 2 in sequence. The nuts are then tightened onto the bolts with a tool to fix the prestressed pipe piles and the flange 2.

[0035] After fixing, the sealing assembly 4 is pulled horizontally by pressing the pressing block 46. The sealing assembly 4 drives the guide sleeve 55 to move horizontally on the outer wall of the guide rod 51. The guide sleeve 55 drives the slider 54 to slide horizontally in the groove 52. The slider 54 pushes the second spring 53 to contract, so that the sealing cylinder 45 is guided to move to the bolts and nuts fastened between the prestressed pipe pile and the flange 2.

[0036] Then, the pressing block 46 is slowly released, and the sealing cylinder 45 is pushed to move in the circular groove 42 by the first spring 44. The sealing cylinder 45 is guided by the sliding of the pressing block 46 and the guide groove 43, so that the sealing cylinder 45 moves to cover the nut and bolt. With the cooperation of the rubber gasket 7, the contact surface between the sealing cylinder 45 and the flange 2 is more sealed, improving the sealing effect. It can seal and cover the nut and bolt after installation, effectively preventing moisture, oxygen and other corrosive substances from contacting the nut surface, thereby slowing down or avoiding rusting of the nut and maintaining the reliability and stability of the connection.

[0037] The above specific embodiments are merely optional embodiments of this utility model.
