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.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-3 This utility model provides a concrete utility pole that can reduce iron attachments and enhance the strength of the pole head, comprising:

[0027] Rod 1, with several reinforcing bars 2 fixedly connected at equal intervals along the inner circumference of rod 1;

[0028] The first flange 3 has a coaxial ring at the end of the rod body 1, and several reinforcing bars 2 extend out of one end of the rod body 1 and are welded to the first flange 3;

[0029] The second flange 4 is located at the end of the first flange 3 away from the rod body 1. A connecting sleeve 5 is coaxially provided between the second flange 4 and the first flange 3, and the two ends of the connecting sleeve 5 are welded to the first flange 3 and the second flange 4 respectively.

[0030] The second flange 4 has a mounting hole 6, which is used to install the crossbeam.

[0031] This invention fixes several reinforcing bars 2 at equal intervals along the inner circumference of the pole body 1, and welds the first flange 3 to the ends of the reinforcing bars 2 extending from the pole body 1, thus forming a stable fixation between the first flange 3 and the pole body 1. Then, the first flange 3 and the second flange 4 are arranged coaxially and welded together using a connecting sleeve 5. By opening an installation hole 6 on the second flange 4, the crossarm is directly welded and fixed using the installation hole 6, thus fixing the first flange 3 to the end of the pole body 1. The connection between the second flange 4 and the crossarm is achieved by welding the first flange 3 and the second flange 4 together with the connecting sleeve 5. Compared with the prior art, this invention eliminates the need for adding a pole top cap and clamps to install the crossarm, effectively reducing iron accessories and enhancing the strength of the pole head.

[0032] In one embodiment of this technical solution, the first flange 3, the second flange 4, and the connecting sleeve 5 can be prefabricated. Before the first flange 3 is fixed to the rod body 1, they are first welded and assembled, and then directly fixed to the reinforcing bar 2 by welding the first flange 3, so as to realize the rapid installation of the overall structure and the rod body 1.

[0033] In another embodiment of this technical solution, in order to enhance the strength of the rod 1, in the area of ​​the rod 1 away from the first flange 3, a support plate 7 is provided around the outer periphery of several reinforcing bars 2, and the several reinforcing bars 2 are welded and fixed to the support plate 7 to enhance the axial support strength of the rod 1.

[0034] In another embodiment of this technical solution, the diameter of the end of the rod 1 does not exceed the diameter of the first flange 3. Preferably, but not limited to, the diameter of the first flange 3 is the same as the diameter of the end of the rod 1, so as to ensure the protective function of the first flange 3 on the rod 1.

[0035] Furthermore, the outer diameter of the connecting sleeve 5 is smaller than that of the second flange 4. The projection of the connecting sleeve 5 in the direction perpendicular to the second flange 4 defines the connection range on the side wall of the second flange 4. The mounting hole 6 is located on the second flange 4 in a region away from the connection range.

[0036] The connecting sleeve 5 is coaxially fixed between the first flange 3 and the second flange 4, and the mounting hole 6 is opened on the second flange 4 in a region away from the connecting sleeve 5 to ensure the connection effect between the crossarm and the mounting hole 6.

[0037] Furthermore, a number of mounting holes 6 are provided, and the mounting holes 6 are evenly distributed around the second flange 4 in a circumferential direction.

[0038] By opening several mounting holes 6, when installing the crossarm, bolt holes corresponding to the mounting holes 6 can be opened on the crossarm, and threaded connections can be made by passing bolts and nuts through them, or the bolts can be passed through and then welded to the crossarm and the second flange 4 for fixation.

[0039] It is understandable that the crossarm is an existing structure, and the connection and installation is carried out by making bolt holes corresponding to the mounting holes 6 and passing bolts through them. This is a conventional technique and will not be described in detail.

[0040] Furthermore, it also includes:

[0041] A number of connecting plates 8 are provided at equal intervals around the outer periphery of the connecting sleeve 5, and the connecting plates 8 are respectively welded to the connecting sleeve 5, the first flange 3 and the second flange 4;

[0042] The projection of the connecting plate 8 along the direction perpendicular to the second flange 4 does not contact the mounting hole 6.

[0043] By fixing several connecting plates 8 to the outer periphery of the connecting sleeve 5, and by welding the first flange 3 and the second flange 4 with the connecting plates 8, the connection strength of the first flange 3, the second flange 4 and the connecting sleeve 5 is enhanced. Furthermore, by extending the connecting plates 8 outward along the axis of the connecting sleeve 5 to the outer side wall of the first flange 3 and the second flange 4, the axial support strength of the connecting sleeve 5 is improved, thereby improving the strength of the end of the rod 1.

[0044] Furthermore, reinforcement 2 is provided with at least 8 bars.

[0045] In this technical solution, the reinforcement 2 is preferably, but not limited to, using φ16mm steel bars. The reinforcement 2 is inserted and fixed inside the rod body 1 through circumferential equal spacing, and the reinforcement 2 is welded to the first flange 3 to ensure the structural strength of the rod body 1 and the connection stability between the rod body 1 and the first flange 3.

[0046] Furthermore, the mounting hole 6 has at least 4 openings.

[0047] By using at least four mounting holes 6 arranged in pairs opposite each other, and selecting two mounting holes 6 that are appropriate and located on the same straight line according to the size of the crossarm, the crossarm is connected and fixed, thereby realizing the connection between the crossarm and the second flange 4.

[0048] Furthermore, the connecting plate 8 is provided with at least 4 pieces.

[0049] The connecting plates 8 are fixed around the connecting sleeve 5 in a circumferential manner, and at least 4 connecting plates 8 can ensure stable support around the connecting sleeve 5.

[0050] This utility model provides an assembly process for concrete utility poles that can reduce iron attachments and enhance pole head strength:

[0051] The positioning mold is used to fix several reinforcing bars 2 axially around the rod body 1. Support plates 7 are sleeved at intervals outside the reinforcing bars 2. Then, the first flange 3 is welded to the end of the reinforcing bars 2. The rod body 1 is then prepared by casting the reinforcing bars 2, so that the reinforcing bars 2 pass through the rod body 1. Then, the connecting sleeve 5 and the second flange 4 are welded and fixed to the first flange 3 in turn. The connecting plate 8 is welded to the outer periphery of the connecting sleeve 5. The welding of the first flange 3 and the second flange 4 is stabilized by the connecting plate 8. The mounting hole 6 is opened on the second flange 4, and the mounting hole 6 does not contact the connecting plate 8 axially. The crossbar is fixed to the second flange 4 through the two mounting holes 6 located on the same straight line. Then, the rod body 1 is installed by a crane.
