[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0027] Refer to Figure 1 and Figure 2 , which discloses the schematic diagram of the structure of the combined antenna arm on the flange of the I-beam after installation.

[0028] A combined antenna support arm 4 for the flange of an I-beam, comprising a first fixture 1 detachably fixed to the I-beam and a second fixture 2 fixed to the first fixture 1. An installation base 3 is installed on the second fixture 2, and an antenna support arm 4 for installing an antenna is installed on the installation base 3.

[0029] Based on the above solution, the second fixture is installed on the I-beam through the first fixture, and the installation base 3 of the antenna support arm 4 for installing the antenna is connected to the second fixture, that is, the antenna support arm is installed on the I-beam (existing original equipment). During the installation operation, the first fixture is detachably connected to the I-beam, avoiding the operation of drilling holes on the I-beam for installation. On the one hand, it ensures the integrity of the I-beam, the integrity and safety of the original equipment, and reduces the probability of installation accidents of the original equipment. On the other hand, it reduces the installation operation difficulty of the antenna support arm and the requirements for the installation ring.

[0030] Of course, in the above solution, it can also be connected to other existing equipment through the first fixture to realize the installation and fixation of the antenna support arm on the existing equipment and ensure that the structural integrity of the existing equipment is not damaged.

[0031] In this technical solution, the first fixture 1 includes a first installation part 11 and a first connection part 12 fixedly connected to each other. The first installation part 11 is detachably installed with the flange of the I-beam, and the second fixture 2 is installed with the first connection part 12. The first installation part 11 and the first connection part 12 are fixedly connected to ensure the strength and stability of the first fixture and the reliable connection between the first fixture and the I-beam. The second connection part is installed with the second fixture, simplifying the installation of the first fixture and the second fixture and avoiding the problem of incorrect installation of the first fixture and the second fixture.

[0032] In this technical solution, two first fixtures 1 are symmetrically arranged and are respectively detachably fixed to the two edges of the flange of the I-beam with the flange of the I-beam. The second fixture 2 is detachably connected between the two first connection parts 12. Two first fixtures 1 are symmetrically arranged, and the second fixture 2 is detachably connected between the two first connection parts 12, so that the shape and size of the first fixture can be selected according to the model of the installed I-beam, improving the applicability of the combined antenna support arm for the flange of the I-beam in this solution. In addition, the second fixture 2 is detachably connected between the two first connection parts 12. Before installation, the first fixture and the second fixture are separated, which is convenient for the turnover and transportation of the first fixture and the second fixture. At the same time, it is also convenient to quickly and simply install the first fixture and the second fixture on the I-beam, reducing the installation difficulty, and single-person installation operation can be realized, reducing the installation cost.

[0033] In this technical solution, the first mounting portion 11 has a first limiting plate 111 and a second limiting plate 112 which are oppositely arranged and parallel. When the first mounting portion 11 is mounted on the flange of the I-beam, the first limiting plate 111 and the second limiting plate 112 are respectively placed on both sides of the flange of the I-beam. A first bolt-nut assembly 13 for detachably fixing the first mounting portion 11 to the flange of the I-beam is connected to the first limiting plate 111. The first connecting portion 12 is fixedly connected to the second limiting plate 112.

[0034] Based on the above solution, the first limiting plate and the second limiting plate form a receiving space. During installation, the flange of the I-beam is placed between the first limiting plate and the second limiting plate, and the first bolt-nut assembly locks the first mounting portion to the flange of the I-beam. The first fixture realizes the detachable fixed connection between the first fixture and the flange of the I-beam through the first bolt-nut assembly. The installation operation of the first fixture is simple and convenient, avoiding the installation methods such as welding or punching commonly used in the prior art during the installation process, ensuring the structural integrity and safety of the flange of the I-beam, and reducing the installation operation difficulty.

[0035] Based on the above solution, the distance between the first limiting plate and the second limiting plate should be greater than the thickness of the flange of the I-beam, which is convenient for the flange of the I-beam to be placed between the first limiting plate and the second limiting plate, and at the same time provides an operating space for the first bolt-nut assembly to realize the installation of the first fixture on the flange of the I-beam.

[0036] Based on the above solution, further, to facilitate the installation of the first fixture on the flange of the I-beam, the first limiting plate and the second limiting plate are parallel to the flange of the I-beam.

[0037] Based on the above solution, to further simplify the structure of the first mounting portion, the first limiting plate and the second limiting plate are connected by a connecting plate, and the connecting plate is perpendicular to the flange of the I-beam, so that the first mounting portion is in a U shape. To further simplify the structure, the first mounting portion is a fixed integral body, and both the first limiting plate and the second limiting plate are fixedly connected to the connecting plate.

[0038] Based on the above solution, the first bolt-nut assembly is composed of a connecting bolt and a connecting nut. A connecting hole or a connecting groove, etc. is opened on the first limiting plate. The front end of the connecting bolt passes through the connecting hole or the connecting groove and abuts against the flange of the I-beam, and then the connecting bolt is locked by the nut, so that the connecting bolt realizes the installation of the first mounting portion and the flange of the I-beam. The connecting hole or the connecting groove is opened during the production process of the first fixture, avoiding on-site hole opening, reducing on-site operation steps, and reducing the installation process difficulty.

[0039] In this technical solution, to simplify the structure of the first fixture, the first connecting portion 12 and the second limiting plate 112 are integrally formed. The first fixture is made of metal or alloy materials, with high strength and hardness. The first connecting portion and the second limiting plate are integrally formed, improving the overall strength of the first fixture.

[0040] As Figure 2 shown in Figure 2 , the first connecting portion is fixedly connected to the second limiting plate and perpendicular to the flange of the I-beam, facilitating the connection between the second fixture and the first connecting portion. Of course, the first connecting portion can also be parallel to the flange of the I-beam. When the first connecting portion is parallel to the flange of the I-beam, there should be a certain distance between the first connecting portion and the flange of the I-beam to facilitate the connection with the second fixture and the connection operation between the second fixture and the first connecting portion.

[0041] In this technical solution, the second fixture 2 includes a second mounting portion 21 and two second connecting portions 22. The two second connecting portions 22 are respectively fixedly connected to both ends of the second mounting portion 21. The mounting base 3 is mounted with the second mounting portion 21, and the two second connecting portions 22 are respectively detachably connected to the two first connecting portions 12.

[0042] Based on the above technical solution, the second fixture is detachably connected to the first fixture, enabling the size of the second fixture to be selected according to the size of the flange of the I-beam, improving the adaptability of the I-beam flange combined antenna arm.

[0043] As Figure 2 shown in Figure 2 , to facilitate the connection between the second connecting portion and the first connecting portion, the second connecting portion and the first connecting portion are in a parallel state, and when connecting, the second connecting portion and the first connecting portion are close to each other.

[0044] In this technical solution, a second bolt-nut assembly 14 detachably connected to the first connecting portion 12 is provided on the second connecting portion 22. A third bolt-nut assembly 23 connected to the mounting base 3 is provided on the second mounting portion 21. Both the second bolt-nut assembly 14 and the third bolt-nut assembly 23 are similar to the first bolt-nut assembly and are composed of a connecting bolt and a connecting nut. When the first connecting portion and the second connecting portion are connected, the connecting bolt passes through the first connecting portion and the second connecting portion and is locked by the connecting bolt. When the mounting base and the second mounting portion are mounted, the connecting bolt passes through the mounting base and the second mounting portion and is locked by the connecting bolt to achieve the detachable fixed mounting of the mounting base and the second mounting portion.

[0045] The mounting base 3 is detachably and fixedly connected to the second mounting portion 21 through the third bolt-nut assembly 23. The detachable and fixed connection between the mounting base 3 and the second mounting portion 21 can adjust and control the mounting base, facilitating the selection of a suitable mounting base, or adjusting the position or direction of the mounting base according to the position and environment of the installation site, improving the flexibility and adaptability of this I-beam flange combined antenna arm.

[0046] In this technical solution, a number of antenna arm mounting parts are provided on the mounting base 3. A fourth bolt-nut assembly 31 is provided on the antenna arm mounting part. The antenna arm 4 is detachably mounted to the mounting base 3 through the antenna arm mounting part and the fourth bolt-nut assembly 31. The antenna arm mounting part is detachably mounted on the mounting base, which realizes that the antenna arm mounting part is detachably connected to the flange of the I-beam, and realizes the installation of the antenna arm mounting part and the on-site equipment. Of course, the antenna arm mounting part can be not only mounted on the flange of the I-beam, but also on the structure of the horizontal plate. The installation principle and operation process are the same as those when mounted on the flange of the I-beam.

[0047] In this technical solution, the antenna arm mounting part includes two connection holes. The fourth bolt-nut assembly 31 includes a U-bolt and a nut. When the antenna arm 4 is installed, the two ends of the U-bolt respectively pass through the two connection holes, and the antenna arm 4 is placed between the U-bolt and the mounting base 3. The connection holes are opened on the mounting base and are completed during the manufacturing process of the mounting base, eliminating the complexity and limitations of on-site hole opening. The inner diameter of the U-bolt is adapted to the outer diameter of the antenna arm 4, so that the U-bolt can lock the antenna arm 4 on the mounting base.

[0048] Based on the above solution, the connection holes and the like that need to be opened on the I-beam flange combined antenna arm are all completed at the manufacturing and processing site, avoiding opening holes at the installation site of the I-beam flange combined antenna arm, reducing the operation steps at the installation site, and simplifying the construction difficulty at the installation site.

[0049] A kind of I-beam flange combined antenna arm provided by the utility model, each part, including the first clamp, the second clamp, the mounting base, the antenna arm, etc., can be processed separately and assembled on-site. Each part realizes modular production. During installation, there is no need to perform drilling or welding operations at the installation site. The installation is simple and fast, and there is no need to damage the original structure on-site, ensuring the integrity and safety of the original structure.

[0050] The technical means disclosed in the technical solution of the utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the utility model.
