Thus, through the bearing beams 430, an internal supporting structure is provided for the hollow bearing outer frame 420, especially the forces received by the first cross frame strip 421 and the second cross frame strip 422 are shared, so that the bearing structure 400 can bear a larger weight as a whole, and the bearing performance of the bearing structure 400 is greatly improved.
In order to avoid the deformation of the bearing bottom plate 410 caused by uneven stress, preferably, each of the bearing beams 430 is disposed below the strain space 480, the bearing beams 430 are uniformly spaced, and each of the bearing beams 430 is abutted to the bearing bottom plate 410. Thus, each of the load-bearing cross beams 430 can share and transmit the force applied to the load-bearing bottom plate 410, so that the load-bearing bottom plate 410 can be kept in the original state after being stressed without deformation, bending or even damage.
In order to further improve the load-bearing performance, two ends of each of the load-bearing vertical beams 440 are respectively connected to the first horizontal frame strip 421 and the second horizontal frame strip 422 and are accommodated in the strain space 480. Each of the bearing beams 430 and each of the bearing vertical beams 440 are accommodated in the strain space 480, and each of the bearing beams 430 is close to the bearing bottom plate 410. In this embodiment, the thickness of the vertical load-bearing beam 440 is smaller than the thickness of the cross load-bearing beam 430. Each of the load-bearing cross beams 430 and each of the load-bearing vertical beams 440 form a grid structure with a thickness of three quarters of the strain space 480. Each of the vertical load-bearing beams 440 is far away from the load-bearing bottom plate 410 and is correspondingly connected with each of the load-bearing cross beams 430. Preferably, each of the vertical load-bearing beams 440 is far away from the load-bearing bottom plate 410 and is vertically connected with each of the load-bearing cross beams 430. In this embodiment, the bearing cross beams 430 are correspondingly provided with connection positions on the same straight line, each of the bearing vertical beams 440 is correspondingly connected with the connection positions of the bearing cross beams 430, for example, each of the bearing vertical beams 440 is correspondingly connected with the connection positions of the bearing cross beams 430 through locking rings, and if each of the bearing vertical beams 440 is correspondingly connected with the connection positions of the bearing cross beams 430 by welding. In this way, each of the bearing beams 430 and each of the bearing vertical beams 440 form a grid structure and are distributed in the strain space 480, and the grid structure is connected with the bearing outer frame 420, and the grid structure and the bearing outer frame 420 form a stressed whole, so that the bearing performance of the bearing structure 400 is greatly improved.
In order to prevent the square base 1 from being gradually disconnected from the load-bearing structure 400 of the load-bearing structure 400 due to vibration during operation, for example, the load-bearing structure 400 of the load-bearing structure 400 further includes a damping cotton block (not shown) disposed between the two load-bearing cross beams 430 for abutting against the bottom of the square base 1, so as to absorb the force generated during vibration and reduce the vibration. For example, each of the load-bearing cross beams 430 is integrally provided with a plurality of connecting columns 431, and the connecting columns 431 are used for connecting the damping cotton blocks above the load-bearing structure 400, such as screwing, clamping, or plugging. In one embodiment, the connecting columns 431 are equally spaced on the load-bearing beam 430. Further, the connecting columns 431 are distributed on the bearing cross beam 430 at equal intervals in a row. Thus, each of the bearing beams 430 has the connecting column 431, when the damping cotton blocks are installed on the bearing structure 400, a proper connecting position can be found through reasonable movement, so that the damping cotton blocks are installed on the bearing structure 400, and the damping cotton blocks are more convenient and faster.
Further, in order to realize the threaded installation of the damping cotton blocks on the bearing structure 400, the connecting column 431 is provided with a threaded installation hole 432, so that the damping cotton blocks are installed on the bearing structure 400 in a threaded manner through the threaded installation hole 432, and during installation, only the bolt of the damping cotton blocks needs to be aligned to the threaded installation hole 432 and screwed in, so that the bolt is fixedly connected with the connecting column 431 in a corresponding position in a threaded manner. Further, the connection column 431 is accommodated in the strain space 480. The top of the connecting column 431 has a planar structure, and the plane of the planar structure is coplanar with the plane of the top surface of the bearing outer frame 420 facing away from the bearing bottom plate 410. That is, the sum of the height of the connection column 431 and the height of the load-bearing cross member 430 is equal to the height of the load-bearing outer frame 420. Thus, the connection column 431 does not protrude out of the plane of the top surface of the bearing outer frame 420, which faces away from the bearing bottom plate 410, so that the top of the bearing structure 400 is provided with a relatively flat plane, and because the connection column 431 is not protruded, the impact on installation or the damage on use of the damping cotton block installed on the bearing structure 400 can not be caused, i.e., the bearing structure 400 is still a cuboid structure on the whole, so that the service life of the simple mobile communication base station convenient to maintain is longer.
In one embodiment, the bearing bottom plate 410 is provided with a plurality of bottom through holes 411, the bearing cross beam 430 is provided with a plurality of mounting screw holes 433 on a side surface facing the bearing bottom plate 410, each bottom through hole 411 is correspondingly and coaxially communicated with one mounting screw hole 433, and a radius of the bottom through hole 411 is equal to a radius of the mounting screw hole 433. For example, a number of bottom perforations 411 are distributed in a matrix. When the load-bearing structure 400 needs to be installed on a reserved installation position, connection can be achieved only by utilizing a fastening bolt in threaded fit with the bottom through hole 411 and the installation screw hole 433, and meanwhile, in the process that the fastening bolt is screwed into the bottom through hole 411 and the installation screw hole 433, the corresponding load-bearing cross beam 430 is enabled to be abutted against the load-bearing bottom plate 410 more closely, so that the overall structural strength of the load-bearing structure 400 is further improved.
