[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates.

[0003] For example, the patent with application number 202421544852.2 discloses an assembled steel structure bracket, which relates to the field of building construction technology. It includes: a support plate, the first surface of the support plate is provided with at least one groove, and the first surface is the opening end of the groove; a moving component is arranged on the support plate for providing support; a gear is arranged inside the moving component for adjusting the position of the moving component, and the moving component includes a first moving part and a second moving part, and the first moving part and the second moving part slide inside the groove, and the first moving part and the second moving part have tooth grooves on one side of the opposite surface. The utility model realizes the coordination of the first moving part, the second moving part, the tooth groove and the gear through the setting of the moving component and the gear, so as to adjust the length of the first moving part and the second moving part at will, thereby avoiding the problem that the adjustment length is fixed due to the setting of the adjustment hole, and it is difficult to adjust according to actual needs.

[0004] The patent with application number 202421494553.2 discloses an assembled steel structure, which relates to the technical field of steel structure. Each adjacent section of steel columns is connected by a clamping assembly. A connecting frame is provided on the outside of the steel column. A placement frame is welded to the bottom of the connecting frame. A positioning assembly and a reinforcement assembly are provided on the top of the placement frame. The positioning assembly is connected to two adjacent steel columns at the same time, and drives the two steel columns to move in the direction of approaching or moving away from the connecting frame. The two ends of the fixing assembly are detachably connected to the two steel columns. The assembled steel structure can replace the manual positioning of the two steel columns through the positioning assembly, making the assembly of the steel structure more convenient and improving the efficiency of steel column assembly. Moreover, the connection of the steel columns is more firmly connected by the use of the connecting frame, the placement frame and the reinforcement assembly. Even if the steel columns are hit or pulled by external forces, the steel columns are not easy to loosen, which greatly improves the stability of the entire assembled building.

[0029] Example 1

[0030] like Figure 1-4 As shown, a large-span steel structure sag compensation component includes a steel truss 3, which is located on the top of the factory building and is fixedly connected to the top of the factory building; the top of the steel truss 3 is connected to the bottom of the connecting structure 2, and the top of the connecting structure 2 is connected to the bottom of the elastic plate 6, the elastic plate 6 is in the shape of a long strip, and a groove 5 is opened on the top of the elastic plate 6, and the groove 5 is arranged along the length direction of the elastic plate 6, and multiple groups of sag compensation mechanisms are installed in the groove 5.

[0031] When in use, the equipment in the factory is hung on the steel truss 3 through steel cables. The steel cables are located between the various connecting structures 2, which can limit the position of the steel cables and prevent the steel cables from moving, thereby preventing the equipment from moving.

[0032] Example 2

[0033] like Figure 1-4 As shown, when other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that connecting plates 1 are provided at both ends of the elastic plate 6, the connecting plate 1 is located above the elastic plate 6, and the bottom end of the connecting plate 1 is fixedly connected to the elastic plate 6.

[0034] By installing the connecting plate 1 on the top of the factory building, the device can be fixed on the top of the factory building, and the steel truss 3 can be further fixed, so that the steel truss 3 can be separated from the top of the factory building and the elastic plate 6 at the same time before it falls. The double protection improves the safety of the steel truss 3.

[0035] The connecting structure 2 includes a steel wire rope 204, a limiting top cover 201, a guide slide bar 202, and a driving ring 203. The guide slide bar 202 is located between the elastic plate 6 and the steel truss 3. The bottom end of the guide slide bar 202 is fixedly connected to the top of the steel truss 3. A driving ring 203 is provided on the top of the guide slide bar 202. The driving ring 203 is sleeved on the top of the guide slide bar 202. The driving ring 203 is slidably connected to the guide slide bar 202. The limiting top cover 201 is located at the top of the guide slide bar 202. The limiting top cover 201 is cylindrical. The limiting top cover 202 is fixedly connected to the top of the guide slide bar 202. The steel wire rope 204 is located between the elastic plate 6 and the driving ring 203. The lower end of the steel wire rope 204 is fixedly connected to the driving ring 203. The upper end of the steel wire rope 204 is fixedly connected to the bottom of the elastic plate 6.

[0036] The sag compensation mechanism includes a hydraulic lifting column 4, a controller 13, a first wire 14, a second wire 7, and a third wire 9. The hydraulic lifting column 4 is located above the elastic plate 6, and the hydraulic lifting end 8 of the hydraulic lifting column 4 faces downward. When the hydraulic lifting column 4 is not started, the hydraulic lifting end 8 can slide in the hydraulic lifting column 4, and the lower end of the hydraulic lifting end 8 extends into the groove 5, and the lower end of the hydraulic lifting end 8 is fixedly connected to the bottom of the groove 5; the controller 13 is located on the left side of the hydraulic lifting end 8, and the controller 13 is located in the groove 5. The controller 13 is connected to the first wire 14 and the second wire 7 respectively. The end of the first wire 14 away from the controller 13 extends to the bottom of the groove 5, and the end of the second wire 7 away from the controller 13 is connected to the hydraulic lifting column 4. The top of the hydraulic lifting column 4 is fixedly connected to the top of the factory building. The hydraulic lifting column 4 is also connected to the upper end of the third wire 9, and the lower end of the third wire 9 extends to the bottom of the groove 5. The sag compensation mechanism also includes a bracket 15, one end of the bracket 15 is fixedly connected to the controller 13, and the other end of the bracket 15 is fixedly connected to the inner wall of the groove 5. The depression compensation mechanism also includes a water storage pipe 17, which is located on the left side of the controller 13, the bottom of the water storage pipe 17 is located in the groove 5, the bottom end of the water outlet pipe 17 is fixedly connected to the bottom of the groove 5, and a plurality of seepage holes 16 are opened on the top of the water storage pipe 17, and the plurality of seepage holes 16 are arranged around the water storage pipe 17.

[0037] Before use, water is poured into the water storage pipe 17 so that the water surface is flush with the seepage hole 16. During use, if the suspended equipment is too heavy, the equipment will pull down the steel truss 3 through the steel cable, causing the steel truss 3 to partially sink and bend. The sunken part of the steel truss 3 drives the nearby guide slide bar 202 to move downward synchronously, causing the limit top cover 201 on the guide slide bar 202 to move downward synchronously, driving the drive ring 203 to move downward, and the drive ring 203 pulls the elastic plate 6 through the steel wire rope 204, causing the elastic plate 6 to partially sink. After the elastic plate 6 is sunken, the elastic plate 6 has an arc, causing the nearby water storage pipe 17 to tilt.

[0038] After the water storage pipe 17 is tilted, the water in the water storage pipe 17 flows out into the groove 5 through the seepage hole 16 and converges into the depression of the elastic plate 6, so that the lower ends of the first wire 14 and the third wire 9 near the depression of the elastic plate 6 are in contact with water, so that the controller 13 forms a loop through the first wire 14, water, the third wire 9, the hydraulic lifting column 4, and the second wire 7 in sequence, so that the controller 13 controls the hydraulic lifting column 4 to start, so that the hydraulic lifting column 4 drives the hydraulic lifting end 8 to move upward, so that the hydraulic lifting end 8 pulls the depression of the elastic plate 6 upward to restore the depression of the elastic plate 6, and the elastic plate 6 drives the limit top cover 201 to move upward through the steel wire rope 204 and the driving ring 203 in sequence, and the limit top cover 201 drives the depression of the steel truss 3 to move upward through the guide slide rod 202, so that the depression of the steel truss 3 is restored.

[0041] When the water storage pipe 17 is tilted, the water in the water storage pipe 17 flows out into the groove 5 through the seepage hole 16 and converges into the depression of the elastic plate 6. The lower ends of the fourth wire 11 and the fifth wire 12 near the depression of the elastic plate 6 are in contact with the water, so that the alarm 10, the fifth wire 12, water, the fourth wire 11, the battery 18, and the sixth wire 19 form a loop, so that the battery 18 starts to power the alarm 10, causing the alarm 10 to sound an alarm to remind the staff in the factory that maintenance is needed.
