Description

Technical Field

[0001] This utility model relates to the field of cement pole technology, specifically a partially prestressed tapered cement pole connection structure. Background Technology

[0002] Partially prestressed cement poles are a type of cement pole combining prestressed and non-prestressed steel reinforcement, primarily used in power, telecommunications, and other fields requiring high-strength support. Their structural feature is the combination of prestressed steel reinforcement and non-prestressed threaded steel, retaining the bending resistance of prestressed cement poles while possessing the flexural strength of non-prestressed cement poles. Compared to purely prestressed cement poles, partially prestressed cement poles sacrifice some mechanical properties and are less structurally strong; therefore, reinforcement is crucial for improving the stability of the installed structure. Current conventional reinforcement methods involve adding embedded parts and increasing the embedment depth. While this approach can improve structural stability to some extent, it is costly and its effectiveness needs further improvement. Summary of the Invention

[0003] The technical problem this invention aims to solve is: how to improve the connection structure between the cement pole and the ground to enhance structural strength and stability.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A partially prestressed conical cement pole connection structure includes a cement pole, a thickened section, side retaining walls, inclined reinforcing piles, an inner support pipe, connecting rods, a main pole, side rods, a bottom retaining wall, and holes. The thickened section is located at the lower part of the cement pole. Side retaining walls and a bottom retaining wall are respectively located at the side and bottom ends of the thickened section. An inner support pipe is pre-embedded in the thickened section, and its bottom end is welded to the bottom retaining wall. Several connecting rods are located at the side ends of the inner support pipe, passing through holes in the side retaining walls and welded to them. The outer ends of the connecting rods extend obliquely upwards and downwards to form inclined reinforcing piles. Each inclined reinforcing pile includes a main pole and several side rods obliquely connected to the main pole.

[0006] Preferably, the thickened part is cylindrical, and the distance between the inner support tube and the side wall is not less than 1 / 4 of the radius of the thickened part.

[0007] Preferably, the main pole and connecting pole of the inclined reinforcement pile are integrated into one structure, and the side poles are welded and fixed to the main pole.

[0008] Preferably, each main pole is coplanar with the axis of the concrete pole, and the main pole and the axis of the concrete pole are at an angle of 30° to 150°.

[0009] Preferably, the reinforcing bars in the cement pole extend to the thickened section and are welded and fixed to the inner support tube.

[0010] In the above technical solution, the cement pole is the main structure of this utility model, and conventional prestressed steel bars can be used inside it. This utility model adds a thickened part made of reinforced concrete at the bottom of the cement pole, which not only strengthens the bottom support area and support strength, but also serves as the load-bearing structure for each inclined reinforcement pile. Among them, the side retaining wall serves as the external enclosure structure of the thickened part and as one of the connection points of the inclined reinforcement piles; the inner support pipe serves as the internal support body of each inclined reinforcement pile; the inner support pipe adopts a pre-embedded structure to ensure its stability as an internal support body; the connecting rod is a natural extension of the inner end of the inclined reinforcement pile, realizing the connection between the inclined reinforcement pile and the inner support pipe, and at the same time realizing the connection between the side retaining wall and the inner support pipe, ensuring the stability of the side retaining wall; the hole is used for the connecting rod to pass through the side retaining wall and serves as the welding point between the connecting rod and the side retaining wall; the bottom retaining wall is welded and fixed to the inner support pipe to ensure its stability at the bottom end of the thickened part, and the bottom retaining wall mainly plays a protective role at the bottom end of the thickened part. Each inclined reinforcing pile extends diagonally upwards and downwards, and its main pole is also equipped with several inclined side poles. Therefore, when the bottom of this utility model is buried in the pole pit, the inclined reinforcing piles form a multi-directional anchoring structure with the soil layer, ensuring the stability of the connection between the cement pole and the ground.

[0011] This utility model provides a partially prestressed tapered cement pole connection structure. This technical solution employs several inclined reinforcing piles to ensure the stability of the cement pole's connection to the ground, while a thickened section is added to the bottom of the cement pole, and pre-embedded internal support pipes ensure the structural strength of the inclined reinforcing piles.
