[0035] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0036] Embodiment 1:

[0037] As Figure 1-12 shown, the embodiment of the utility model provides an adjustable bracket system for a closed square steel used in the installation of complex mechanical and electrical pipelines, which includes an elastic base 1, a main stressed closed square steel 2, and a plurality of cross beams 3 arranged in parallel between the main stressed closed square steel 2. The elastic base 1 is arranged at the end of the main stressed closed square steel 2 for fixing the position of the main stressed closed square steel 2. The two ends of the cross beam 3 are respectively connected and fixed to the main stressed closed square steel 2 through vertically height-adjustable connecting pieces 4. A plurality of horizontally adjustable pipe clamps 5 are detachably installed on the cross beam 3.

[0038] In this embodiment, the elastic base 1 includes a bottom plate 11 and a connecting pipe 12 on the bottom plate 11 for connecting and fixing to the main stressed closed square steel 2. The bottom plate 11 is provided with a first fixing hole 111, and an anchor bolt 13 is arranged in the first fixing hole 111. The anchor bolt 13 is fixed by using a special concrete expansion anchor bolt plus planting steel glue. This fixing method is that after the expansion anchor bolt is fully expanded, it locks the base material, and then the special planting steel glue is used to seal, preventing concrete chips and other impurities from overflowing due to the shaking of the bracket, which may pollute the clean environment, thus playing a protective role. The connecting pipe 12 is composed of two U-shaped pipes with opposite openings. An elastic seam 14 is arranged at the connection of the two U-shaped pipes. The gap of the elastic seam 14 is 1-2 mm. With the design of the elastic seam 14, when the main stressed closed square steel 2 is sleeved and connected, once the through bolt is tightened and stressed, the gap tightens and becomes smaller, which has a constraining effect on the main stressed closed square steel 2, solving the problem of unstable shaking of the bracket. At the same time, due to the certain elasticity of the connecting pipe 12, it can absorb the energy generated by the shaking of the pipeline during installation and operation, thereby reducing the damage to the bracket and the structure. Long strip-shaped installation holes 121 are arranged on the opposite bottom surfaces of the two U-shaped pipes. The inner side surface of the installation hole 121 has a serrated structure, which can meet the position adjustment of less than 5 mm. At the same time, the through connection method is adopted, which is safe and stable.

[0039] In this embodiment, the main load-bearing closed square steel 2 adopts a straight-sided square steel structure. Specifically, square steels of specifications such as 40*40*2.0, 40*60*2.5, 40*80*2.75, 80*80*3.0, 80*120*3.5, 80*160*4.0, etc. can be used. On two opposite surfaces of the main load-bearing closed square steel 2, 10.5mm through-holes are respectively opened. Only through-holes 21 on two surfaces are required, and the hole pitch is 50mm. The material is ordinary Q235B carbon steel. The opening ratio of the through-holes 21 on the main load-bearing closed square steel 2 is 1.1% - 2.4%. At the same time, only two surfaces are opened, which is extremely convenient for cleaning surface dust and not easy to accumulate dust. At the same time, the stiffness and strength of the main load-bearing closed square steel 2 are ensured. In order to be completely enclosed, a sealing rubber strip can be used for opening sealing to ensure that no dust accumulates, which is completely suitable for use in clean areas. The surface treatment of all the main load-bearing closed square steels 2 in this embodiment can adopt processes such as galvanizing, epoxy spraying, zinc-aluminum-magnesium, low surface energy coatings, etc., so that the use environment does not produce secondary pollution, the cleanliness is better maintained, the effect is more beautiful, the cost is low, and the cost performance is high.

[0040] In this embodiment, the design of the vertically height-adjustable connector 4 can freely adjust the vertical height, and the minimum distance is 4.6mm. Moreover, the horizontal positioning can be freely found. The vertically height-adjustable connector 4 includes a main body 41, shear-resistant components 42 symmetrically arranged on both sides of the main body 41, and shear-resistant bolts 43. A channel for the main load-bearing closed square steel 2 to pass through is provided on the main body 41. The shear-resistant bolts 43 sequentially pass through the two shear-resistant components 42, the main body 41 located between the two shear-resistant components 42, and the main load-bearing closed square steel 2 to fix the cross beam 3 on the main load-bearing closed square steel 2. A second fixing hole 411 for connecting and fixing with the cross beam 3 is provided on the main body 41. The hole position on the cross beam 3 is directly fixed by passing a screw through the second fixing hole 411.

[0041] In this embodiment, the vertically height-adjustable connecting member 4 further includes a positioning hole 412 provided on the main body 41 and a detachable laser level 44 disposed in the positioning hole 412. A marking recognition groove 413 is provided on one side of the positioning hole 412, and a small short column is provided on the laser level 44. In this way, the laser level 44 can be temporarily hung at the position of the positioning hole 412 during installation. For the marking recognition groove 413, when installing one side of the fitting first, press the horizontal key of the laser level 44 at this time, and the laser level 44 will emit a horizontal laser beam onto the other main load-bearing closed square steel 2. At this time, as long as the marking recognition groove 413 of the other vertically height-adjustable connecting member 4 is aligned with the laser beam, and then install the cross beam 3, it can be fully ensured that the cross beam 3 is horizontal, and a large and bulky spirit level can be dispensed with. At the same time, press the key in the vertical direction of the laser level 44 to adjust the perpendicularity of the main load-bearing closed square steel 2, and at the same time display the installation length in the vertical direction. The installation ruler can no longer be used at all, greatly shortening the construction period and facilitating installation. When all the dimensions are completely determined, the laser level 44 can be removed. Because of its small size, it can be carried around and reused, which is very convenient for construction.

[0042] In this embodiment, the shear-resistant assembly 42 includes a shear-resistant tooth core 421 and a shear-resistant tooth core sleeve plate 422. Connecting holes 423 having the same shape as the outer shape of the shear-resistant tooth core 421 are respectively provided on the shear-resistant tooth core sleeve plate 422 and the main body 41. A part (half) in the thickness direction of the shear-resistant tooth core 421 is embedded in the connecting hole 423 on the shear-resistant tooth core sleeve plate 422, and the other part (the other half) in the thickness direction is embedded in the connecting hole 423 on the main body 41. The outer ring of the shear-resistant tooth core 421 is a serrated structure. The shear-resistant tooth core 421 is precisely manufactured from alloy steel. The outer ring of the shear-resistant tooth core 421 has a unique tooth angle (75˚ - 90˚) and tooth height, which fully utilizes the limited space and length. The shear-resistant tooth core 421 and the shear-resistant tooth core sleeve plate 422 are separately manufactured and then connected to be integrally stressed later, greatly reducing the manufacturing cost and improving the efficiency, and meeting the integrated shear resistance when embedded in the main body 41. The shear-resistant tooth core sleeve plate 421 is also made of low alloy steel and is sleeved with the shear-resistant tooth core 421. The thickness of the shear-resistant tooth core 421 is twice that of the shear-resistant tooth core sleeve plate 422. Therefore, half of the shear-resistant tooth core 421 is clamped in the shear-resistant tooth core sleeve plate 422. The shear-resistant tooth core sleeve plate 422 plays a role in protecting the shear-resistant tooth core 421, improving the shear resistance of the shear-resistant tooth core 421, and also facilitating the installation operation together with the shear-resistant tooth core 421, which is beneficial to on-site production and installation.

[0043] In this embodiment, the shear bolt 43 is made of high-strength 8.8-grade carbon steel bolt, which can completely resist the main shear force and tensile force, and play a key role in restraining and positioning. A protruding shear key pin 431 is provided on the inner side of the root of the shear bolt 43, and the inner circular hole 4211 on the shear tooth core 421 for the shear bolt 43 to pass through is connected with a groove 4212 that cooperates with the protruding shear key pin 431. The protruding shear key pin 431 cooperates with the groove 4212 during installation, and will not rotate when the nut is tightened during installation. In this way, there is no need to manually lock and tighten both sides during installation, which greatly improves the installation efficiency. At the same time, the proper size design of the protruding shear key pin 431 means that when the external force tightens the nut to a certain torque value, the protruding shear key pin 431 will automatically break, thereby indicating that the torque value meets the installation requirements, and there is no need to use a torque wrench for detection, which is convenient for installation.

[0044] In this embodiment, the horizontally adjustable pipe clamp 5 is in an "Ω"-shaped structure. The horizontally adjustable pipe clamp 5 is composed of two sections of sub-pipe bundles, which are connected by adjusting bolts 51. The bottom surface of the horizontally adjustable pipe clamp 5 is provided with a long strip-shaped adjusting hole 52. The adjusting hole 52 cooperates with the hole position on the crossbeam 3 for the installation and fixation of the horizontally adjustable pipe clamp 5. The unique Ω-shaped structural design of the horizontally adjustable pipe clamp 5 meets the installation and adjustment requirements of the main force-bearing closed square steel 2. Since the main force-bearing closed square steel 2 adopts a hole spacing of 50mm, the crossbeam 3 is required to meet the adjustment within a small range in the horizontal direction. The bottom surface of the horizontally adjustable pipe clamp 5 is designed as a strip-shaped adjusting hole 52, which can be freely adjusted within a range of 30mm. The top 5 of the horizontally adjustable pipe clamp is connected by a through-through adjusting bolt 51. When the upper adjusting bolt 51 is slightly adjusted, according to the lever principle, the bottom movement amount becomes 10 times larger, which fully meets the requirements.

[0045] Embodiment 2:

[0046] The difference between this embodiment and the embodiment 1 is that the main load-bearing closed square steel 2 is a strong rib square steel structure, and the rest of the structure is the same as that of embodiment 1.
