Description

Technical Field

[0001] This utility model relates to the field of utility pole technology, specifically to a precast concrete utility pole column for splicing. Background Technology

[0002] Utility poles are vertical structures used to support power, communication and other cable lines. They are usually made of wood, steel or concrete, with concrete utility poles being the most common. They are generally prefabricated and then transported to the site for installation.

[0003] In the prior art, Chinese Patent Application No. CN202210644011.8 discloses a cement utility pole, including a pole body, a guide rail, and a climbing component. By setting up the climbing component and the guide rail, the climbing component moves upward along the guide rail, thereby carrying workers and tools and materials into the air to install or repair the power lines. This avoids workers using climbing tools to climb, saving climbing time and allowing for faster completion of installation or repair. It also avoids expending a lot of physical effort on climbing, allowing workers to concentrate on installation or repair, thus improving work efficiency. Since each cement utility pole is equipped with a climbing component, multiple power lines can be installed or repaired simultaneously, saving waiting time, improving work efficiency, reducing the impact of installation or repair on the power supply line, and thus improving the reliability of the power supply line.

[0004] Based on the above information, it can be seen that existing concrete utility poles are generally integral structures, cast as a single piece during prefabrication. However, in actual use, due to the large length of the utility poles, integral prefabrication makes subsequent handling and transportation inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated concrete pole column for splicing, so as to solve the problem of inconvenience in handling and transportation mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precast concrete utility pole column for splicing, comprising an embedded base cast underground, an mounting plate fixedly installed at the middle position of the upper surface of the embedded base using fixing bolts, a longitudinally arranged lower column inserted and installed inside the embedded base, and a corresponding upper column provided at the upper end of the lower column, wherein the diameter of the upper column is smaller than the diameter of the lower column, the upper column and the lower column form a butt-joint splicing structure, and a stabilizing and reinforcing mechanism is provided on the outer side of the upper column and the lower column; a first steel mesh is provided inside the lower column, and a second steel mesh is provided inside the upper column.

[0007] Preferably, the first steel mesh includes three parts: longitudinal steel bars, transverse steel bars, and butt steel bars, and the butt steel bars protrude outside the upper end of the lower column.

[0008] Preferably, the butt reinforcing bars and the butt holes opened on the lower surface of the upper column form an insertion-type interlocking structure.

[0009] Preferably, the stabilizing and reinforcing mechanism includes a first docking ring and a second docking ring, both of which are made of steel.

[0010] Preferably, the first docking ring is fixedly installed to the lower column using a locking bolt installed through its side, and the second docking ring is fixedly installed to the upper column using a locking bolt installed through its side.

[0011] Preferably, the first docking ring and the second docking ring are fixedly installed using docking bolts and nuts, and rubber shock-absorbing pads are fixedly installed on the inner surfaces of both the first docking ring and the second docking ring.

[0012] Preferably, the mounting plate has stabilizing blocks that are evenly spaced fixedly installed on its upper surface, and the stabilizing blocks are slidably connected to the positioning grooves formed on the lower outer surface of the lower column.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This spliced ​​precast concrete utility pole column adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The column is divided into two parts: the lower column and the upper column. During prefabrication, the lower column and the upper column are produced separately and then assembled for use. This structure makes the overall length smaller during handling and transportation, which is conducive to handling and transportation operations.

[0015] Furthermore, when splicing the upper and lower columns, the exposed butt reinforcing bars on the upper part of the lower column are aligned with the butt holes opened on the lower surface of the upper column and inserted. The interlocking of the two is used to initially fix the upper and lower columns together, which facilitates subsequent operations.

[0016] Furthermore, the first mating ring is fixedly installed to the outside of the lower column, and the second mating ring is fixedly installed to the outside of the upper column. Then, the first mating ring and the second mating ring are fixed together with mating bolts, thereby improving the firmness of the connection between the upper column and the lower column.

[0017] 2. When installing the lower column, the positioning groove on the outer surface of its lower end slides in correspondence with the stabilizing block on the upper end of the mounting plate to achieve positioning. After installation, the stabilizing block is used to improve the stability of the lower end of the lower column. Attached Figure Description

The lower end of the lower column 4 is inserted into the pre-embedded base 1 (the pre-embedded base 1 is pre-cast underground and has holes). The mounting plate 2 is fixed on the upper surface of the pre-embedded base 1 using fixing bolts 3. When the lower column 4 is inserted, the positioning groove 14 on its outer surface slides in correspondence with the stabilizing block 15 on the upper surface of the mounting plate 2. Finally, the stabilizing block 15 is used to achieve the purpose of support and stability. Then, the upper column 5 is installed on top of the lower column 4 to achieve the purpose of splicing and assembly.

The first steel mesh 6 includes three parts: longitudinal steel bar 601, transverse steel bar 602 and butt steel bar 603. The butt steel bar 603 protrudes outside the upper end of the lower column 4, and the butt steel bar 603 and the butt hole 8 opened on the lower surface of the upper column 5 form an insertion type interlocking structure.

[0030] When assembling the upper column 5 and the lower column 4, first align the exposed butt reinforcing bar 603 at the upper end of the lower column 4 with the butt hole 8 on the lower surface of the upper column 5, and then insert the butt reinforcing bar 603 into the butt hole 8 to achieve initial fixation.

[0031] Example 1: Please refer to Figures 6-7 In order to achieve the purpose of stabilization and reinforcement, this embodiment provides the following technical solution, which specifically discloses that: a stabilization and reinforcement mechanism is provided on the outer side of the upper column 5 and the lower column 4.
