Description

A prestressed concrete pole frame structure Technical Field

[0001] This utility model belongs to the field of prestressed concrete pole production technology, and in particular relates to a prestressed concrete pole skeleton structure. Background Technology

[0002] During the production of prestressed concrete poles, the pole frame placed in the mold will sink to the lower half of the mold due to the weight of the concrete when it is poured. In addition, during the tensioning process, the main reinforcement bars are in a curved state in the mold due to the influence of the support ring. It is difficult for the tension force to straighten the main reinforcement bars, resulting in uneven thickness of the protective layer of the main reinforcement bars. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model provides a prestressed concrete pole frame structure that enables the protective layer thickness of the main reinforcement to be more uniform.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A prestressed concrete pole frame structure, comprising:

[0006] The main reinforcement assembly includes several parallel main reinforcement bars, which are evenly arranged circumferentially.

[0007] Several support rings are evenly arranged along the axis of the main reinforcement assembly, with the axis of the support rings coinciding with the axis of the main reinforcement assembly, and any support ring connecting all the main reinforcements.

[0008] Several washer assemblies are evenly arranged along the axial direction of the main rib assembly. Each washer assembly includes several washers for abutting against the inner wall of the mold, and the washers are coaxially connected to the main ribs respectively.

[0009] The beneficial effects of adopting the above technical solution are as follows: Several washer assemblies connected to the main reinforcement assembly are circumferentially restricted by the inner wall of the mold that abuts on their outer side. The circumferential position of the main reinforcement assembly can be restricted at different axial positions of the main reinforcement assembly, so as to effectively restrict the relative position of the main reinforcement and the mold. That is, during concrete pouring and centrifugal production, the main reinforcement will not move relative to the mold on any cross-section of the mold, and always keep the main reinforcement assembly coaxial with the mold. This makes the protective layer thickness of the main reinforcement more uniform after centrifugal production. In addition, the main reinforcement provides an installation reference for the washers, so as to facilitate the quick positioning and installation of the washers.

[0010] Furthermore, a spiral rib is wound around the outer side of the main rib assembly along a cylindrical spiral line, and the spiral rib is fixedly connected to the main rib that contacts its inner side.

[0011] The beneficial effects of adopting the above technical solution are: the spiral reinforcement can further enhance the overall structural stability of the pole frame.

[0012] Furthermore, the spiral reinforcement is tied to the main reinforcement it contacts.

[0013] The beneficial effect of adopting the above technical solution is that this arrangement makes the connection between the spiral reinforcement and the main reinforcement more stable.

[0014] Furthermore, the outer diameter of the support ring matches the inscribed circle diameter of all the main reinforcement bars, and any support ring is tied to the main reinforcement bar that contacts its outer side.

[0015] The beneficial effects of adopting the above technical solution are: this setting allows the support ring to provide stable support for all main reinforcement bars on the inner side.

[0016] Furthermore, after the washers are fitted onto the main reinforcing bars, they are fixedly connected to the support rings.

[0017] The beneficial effects of adopting the above technical solution are: the positioning installation can be achieved by fitting the washer onto the main reinforcement, which helps to improve the production efficiency of the pole frame.

[0018] Furthermore, the washer is coaxially provided with mounting holes, the diameter of which matches the outer diameter of the main reinforcement.

[0019] The beneficial effect of adopting the above technical solution is that the washer can be accurately fitted onto the main reinforcement bar in this way.

[0020] Furthermore, the washer is tied to the support ring.

[0021] Furthermore, the outer diameter of all washers in the same washer assembly matches the inner diameter of the mold.

[0022] The beneficial effect of adopting the above technical solution is that, in this way, all washers in the same washer assembly can jointly abut against the inner wall of the mold.

[0023] Furthermore, the number of washers in the same washer assembly is no more than the number of main bars in the main bar assembly, and the washers in the same washer assembly are evenly distributed along the circumference of the main bar assembly.

[0024] Furthermore, the positions of the washer assembly and the support ring are matched in the axial direction of the main reinforcement assembly.

[0025] The beneficial effects of adopting the above technical solution are as follows: This arrangement allows the axial positions of the washer assembly and the support ring on the main reinforcement assembly to be close to each other, so that the circumferentially arranged main reinforcement can be effectively fixed by the support ring.

[0026] The beneficial effects of this utility model are as follows:

[0027] Several washer assemblies connected to the main reinforcement assembly are circumferentially restricted by the inner wall of the mold that abuts against their outer sides. This restricts the circumferential position of the main reinforcement assembly at different axial positions, effectively limiting the relative position of the main reinforcement and the mold. That is, during concrete pouring and centrifugal production, the main reinforcement will not move relative to the mold on any cross-section of the mold, and the main reinforcement assembly will always remain coaxial with the mold. This makes the protective layer thickness of the main reinforcement more uniform after centrifugal production. In addition, the main reinforcement provides an installation reference for the washers, so as to facilitate the quick positioning and installation of the washers. Attached Figure Description

[0035] This utility model provides a prestressed concrete pole frame structure, as shown in Figure 1, a main reinforcement assembly, which includes a number of parallel main reinforcement bars 3, which are evenly arranged circumferentially.

[0036] Several support rings 2 are evenly arranged along the axis of the main reinforcement assembly. The axis of the support rings 2 coincides with the axis of the main reinforcement assembly. Any support ring 2 connects all the main reinforcement 3.

[0037] A number of washer assemblies are evenly arranged along the axial direction of the main rib assembly. Each washer assembly includes several washers 4 for abutting against the inner wall of the mold 1. The washers 4 are coaxially connected to the four main ribs 3, and the four washers 4 are also evenly arranged along the circumference of the main rib assembly.

[0038] Among them, the main rib 3 can be prestressed steel wire; the mold 1 can be disassembled in half, that is, the mold 1 includes two parts: the upper inner liner and the lower inner liner.

[0039] Understandably, the several washer assemblies connected to the main reinforcement assembly are circumferentially restricted by the inner wall of the mold 1 on their outer side. This restricts the circumferential position of the main reinforcement assembly at different axial positions, effectively limiting the relative position of the main reinforcement 3 and the mold 1. That is, during concrete pouring and centrifugal production, the main reinforcement 3 will not move relative to the mold 1 on any cross-section of the mold 1, and will always keep the main reinforcement assembly coaxial with the mold 1. This makes the protective layer thickness of the main reinforcement 3 more uniform after centrifugal production. In addition, the main reinforcement 3 provides an installation reference for the washer 4, so as to facilitate the quick positioning and installation of the washer 4.

[0040] It should be noted that in this embodiment, eight main ribs 3 are provided; the number of washer assemblies is the same as the number of support rings 2; during installation, the same washer assembly includes at least three washers 4, and at least two washers 4 abut against the lower inner liner of the mold.

[0042] Understandably, the spiral reinforcement 5 can further enhance the overall structural stability of the pole frame.

[0043] In one embodiment, the spiral rib 5 is tied to the main rib 3 it contacts, so that the connection between the spiral rib 5 and the main rib 3 is more stable.

[0044] In one embodiment, the outer diameter of the support ring 2 matches the inner circle diameter of all the main reinforcement bars 3, and any support ring 2 is tied to the main reinforcement bar 3 that contacts its outer side, so that the support ring 2 can provide stable support for all the main reinforcement bars 3 on the inner side.

[0045] In one embodiment, the washer 4 is fitted onto the main rib 3 and then fixedly connected to the support ring 2.

[0046] Understandably, the placement of the washer 4 on the main reinforcement 3 allows for positioning and installation, which is beneficial for controlling the quality of the pole frame and improving production efficiency.

[0047] In one embodiment, the washer 4 is coaxially provided with a mounting hole, the diameter of which matches the outer diameter of the main rib 3, so that the washer 4 can be accurately fitted onto the main rib 3.

[0048] In one embodiment, the washer 4 is tied to the support ring 2.

[0049] In one embodiment, the outer diameter of all washers 4 in the same washer assembly matches the inner diameter of the mold 1, so that all washers 4 in the same washer assembly can abut against the inner wall of the mold 1 together.

[0050] In one embodiment, the number of washers 4 in the same washer assembly is no more than the number of main ribs 3 in the main rib assembly, and the washers 4 in the same washer assembly are evenly arranged along the circumference of the main rib assembly.

[0051] In one embodiment, the washer assembly and the support ring 2 are positioned close to each other along the axial direction of the main reinforcement assembly, so that the axial positions of the washer assembly and the support ring 2 on the main reinforcement assembly are close to each other, so as to effectively fix the circumferentially arranged main reinforcement 3 by means of the support ring 2.
