Description

Technical Field

[0001] The present application relates to the technical field of steel bar brackets, and in particular to a steel bar bracket for casting a lamp pole. Background Art

[0002] In the urban lighting system, lamp poles are an important component, and their installation quality and stability directly affect the safety and effect of the lighting system. The existing lamp poles are connected to the embedded parts with upright steel mesh through nuts. Although this design is simple, there are some problems in actual use.

[0003] Firstly, the tail of the lamp pole is prone to bending due to concentrated stress load, which affects the overall strength and service life of the lamp pole; secondly, the nuts of the lamp pole are prone to loosening due to ground vibration or air blowing, resulting in poor stability of the lamp pole after installation. Utility Model Content

[0004] The problem to be solved by the present application is that the existing lamp pole is not only prone to bending due to the concentrated stress load at the tail, but also the nut is easily loosened due to ground vibration or air blowing.

[0005] In order to solve the above-mentioned technical problems, the present application provides a steel bar support for casting a lamp pole, comprising a lamp pole with a base, an embedded part for pre-embedded operation is arranged directly below the lamp pole, an anti-bending part for improving the bending resistance is arranged at the tail of the lamp pole, and a connecting part capable of realizing anti-loosening connection operation is arranged between the lamp pole and the embedded part.

[0006] Since the steel bar support of the present application is designed with embedded parts, anti-bending parts and connecting parts, it is possible to realize the embedded fixing operation of the lamp pole through the embedded parts, realize the anti-bending operation of the tail of the lamp pole through the anti-bending parts, and realize the anti-seismic and anti-detachment operation between the lamp pole and the embedded parts through the connecting parts, which solves the problem that the lamp poles in the prior art are not only prone to bending due to the concentrated stress load at the tail, but also prone to loosening of nuts due to ground vibration or air blowing.

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0017] The present application relates to a steel bar support 9 for casting a lamp pole 1, such as Figure 1-8 As shown, the steel bar 9 bracket includes a lamp pole 1 with a base 3, and an embedded part 5 for pre-embedded operation is arranged directly below the lamp pole 1. In order to prevent the tail of the lamp pole 1 from bending due to concentrated stress load, an anti-bending part 2 for improving the bending resistance is added to the tail of the lamp pole 1. In order to prevent the nut 11 from loosening due to ground vibration or air blowing on the lamp pole 1, a connecting part 4 that can realize anti-loosening connection operation is added between the lamp pole 1 and the embedded part 5.

[0018] The embedded parts 5 include a base 8, steel bars 9, and rib rings 10. The base 8 is arranged directly below the lamp pole 1 and is coaxially sleeved therewith. The steel bars 9 connected to the base 8 are evenly arranged in the circumferential direction. In order to improve the anti-slip ability of the steel bars 9, the lower end of the steel bars 9 is in a "J" shape. The upper end of the steel bars 9 penetrates the base 8 and the base 3 of the lamp pole 1. In order to achieve the fixing operation of the steel bars 9, the steel bars 9 are connected and fixed to the lower surface of the base 8 and the upper surface of the base 3 respectively through connecting parts 4. Since there are multiple steel bars 9 and they are arranged in the vertical direction, and the bending resistance will be greatly reduced with the increase of length, therefore, in order to improve the overall bending strength between the steel bars 9, a plurality of annular rib rings 10 sleeved therewith are evenly and spacedly arranged in the axial direction of the steel bars 9. The rib rings 10 can be welded and fixed to the steel bars 9.

[0019] The anti-bending member 2 includes a raft seat 6 and a core rod 7. The raft seat 6 is arranged directly below the base 3 and abuts against it. In order to improve the bending strength of the lamp pole 1, the raft seat 6 as a whole is a trident structure with an angle of 120°. In order to further improve the connection strength of the raft seat 6, a plurality of core rods 7 that penetrate the base 3 and the susceptor 8 are evenly arranged inside the raft seat 6. The core rod 7 can be a solid metal rod or a cast cement rod with a steel mesh 9.

[0020] The connecting member 4 includes a nut 11 and a gasket 12. The nut 11 is threadedly connected to the upper part of the steel bar 9. In order to improve the anti-loosening ability of the nut 11, a gasket 12 is additionally provided between the nut 11 and the upper surface of the base 3 and the lower surface of the base 8, which is sleeved with the steel bar 9. There are two gaskets 12 and they are arranged to overlap each other. The end faces of the gaskets 12 on both sides form an inclination angle in the circumferential direction. The inclination angle of the gaskets 12 that bites each other is the inner angle, and the inclination angle of the gasket 12 that contacts with the base 3, the base 8 and the nut 11 is the outer angle. The cross-sectional area of ​​the inner angle is 2.5 times that of the outer angle. The inclination angle of the inner angle is 12°, and the inclination angle of the outer angle is 17°. In order to ensure the anti-slip effect of the gasket 12, the inner angle needs to be larger than the thread inclination angle of the upper end of the steel bar 9, so that when the nut 11 is tightened, the two gaskets 12 will produce a wedge effect, which can effectively prevent the nut 11 from loosening.

[0021] When in use, first sink the embedded part 5 to the installation position, then put the lamp pole 1 on the upper part of the base 8, and then use the connecting part 4 to firmly connect the base 3 and the base 8, and then put the raft seat 6 on the bottom of the lamp pole 1, and then perform vertical drilling along its circumferential direction, and then implant the core rod 7 into it, and then the installation operation of the lamp pole 1 is completed. The arranged raft seat 6 and core rod 7 can effectively improve the bending resistance of the tail of the lamp pole 1, and the nut 11 and gasket 12 connected between the base 3 and the upper end of the steel bar 9 can effectively realize the earthquake-resistant and anti-detachment operation.
