[0025] The inner support member 100 includes an upper end support adjustment assembly 10, an intermediate rotation support assembly 20 and a lower end support assembly 30 which are sequentially arranged from top to bottom.

[0026] like Figure 2 , Figure 3 As shown, the upper end support adjustment assembly 10 includes an upper end adjustment member and an upper top block 12 arranged at the upper end of the upper end adjustment member.

[0027] like Figure 2 , Figure 4 As shown, the intermediate rotation support assembly 20 includes a threaded sleeve 21 and a rotating handle 22. The rotating handle 22 is connected to the side wall of the threaded sleeve 21 or penetrates the side wall of the threaded sleeve 21. In this embodiment, the rotating handle 22 is a rod, and the side wall of the threaded sleeve 21 is provided with a through hole, and the rotating handle 22 can be inserted into the through hole or taken out from the through hole. When the rotating handle 22 is inserted into the through hole, the rotating handle 22 is pushed along the circumference of the threaded sleeve 21 to drive the threaded sleeve 21 to rotate.

[0028] like Figure 2 , Figure 5 As shown, the lower end support assembly 30 includes a lower end adjustment member, a lower top block 32 arranged at the lower end of the lower end adjustment member, and a safety net hook body 33 connected to one side of the lower top block 32 .

[0029] The lower end of the upper end adjusting member and the upper end of the lower end adjusting member are respectively threadedly connected to the two ends of the threaded sleeve 21 to adjust the distance between the upper top block 12 and the lower top block 32 .

[0030] Specifically, the upper end adjusting member includes an upper end adjusting screw 11 , which is threadedly connected to the threaded sleeve 21 , and the upper end of the upper end adjusting screw 11 abuts against the lower end of the upper top block 12 .

[0031] The lower end of the upper top block 12 is provided with a countersunk hole, and the upper end of the upper end adjusting screw 11 is located in the countersunk hole. The upper end of the upper end adjusting screw 11 is provided with a truncated cone, the diameter of which is larger than the diameter of the upper end adjusting screw 11, and the truncated cone is located in the countersunk hole. Through the design of the countersunk hole and the truncated cone, the upper top block 12 and the upper end adjusting screw 11 can rotate relative to each other, but not separate, and the vertical displacement of the upper top block 12 and the upper end adjusting screw 11 is now understood, and the vertical direction can be understood as the axial length direction of the upper end adjusting screw 11. In this embodiment, the upper end adjusting member, the threaded sleeve 21, and the lower end adjusting member are coaxial.

[0032] The upper support adjustment assembly 10 further includes a locking nut 13 ; the locking nut 13 is threadedly connected to the upper adjustment screw 11 and is located below the upper top block 12 .

[0033] The upper end adjusting screw 11 includes a first threaded section, a smooth section 14 and a second threaded section arranged in sequence from top to bottom; the first threaded section is threadedly connected to the locking nut 13 , and the second threaded section is threadedly connected to the threaded sleeve 21 .

[0034] By rotating the locking nut 13, the matching height between the locking nut 13 and the first threaded section of the upper adjusting screw 11 can be adjusted, especially the upper end of the locking nut 13 can be pressed against the lower end of the upper top block 12 to press it against the lower plate surface of the upper flange plate 201 of the steel beam 200.

[0035] The lower end adjusting member includes a lower end adjusting screw 31, the upper end of which is threadedly connected to the threaded sleeve 21, and the lower end of which is connected to the lower top block 32. The side wall of the lower top block 32 is provided with a threaded hole, and one end of the safety net hook body 33 is threadedly connected to the threaded hole.

[0036] The threaded sleeve 21 is provided with two sections of threads along its axial direction, one section of the threads is used for threaded connection with the upper end adjusting screw 11, and the other section of the threads is used for threaded connection with the lower end adjusting screw 31, and the through hole provided on the side wall of the threaded sleeve 21 for cooperating with the rotating handle 22 is provided between the two sections of threads.

[0037] When the handle 22 is rotated to drive the threaded sleeve 21 to rotate, the upper adjusting screw 11 and the lower adjusting screw 31 are synchronously moved closer or farther away. When they are synchronously moved away, the corresponding upper top block 12 and lower top block 32 are moved away from each other until the upper top block 12 abuts against the lower plate surface of the upper flange plate 201 and the lower top block 32 abuts against the upper plate surface of the lower flange plate 202. In addition, the locking nut 13 is rotated again to tighten the locking nut 13 under the upper top block 12 to prevent the upper top block 12 from sinking, so as to ensure the stability of the inner support member 100 supported between the upper flange plate 201 and the lower flange plate 202 of the steel beam 200.

[0038] In order to improve the supporting effect and prevent the inner support member 100 from moving laterally, the upper end of the upper top block 12 and the lower end of the lower top block 32 are respectively provided with anti-skid grooves which are frictionally matched with the upper flange plate 201 and the lower flange plate 202 .

[0039] like Figure 7 As shown, there are multiple inner support members 100, which are arranged at intervals along the length direction of the steel beam 200. The safety net is arranged between the two steel beams 200, and the two sides of the safety net are respectively hung on the safety net hook body 33 of the inner support member 100 on the two steel beams 200. Since the safety net hook body 33 is threadedly connected with the lower top block 32, the safety net hook body 33 can be rotated and moved radially along the lower top block 32, pulling the safety net 300 or twisting the hanging node with the safety net 300, so as to prevent the safety net 300 from falling off from the safety net hook body 33.

[0040] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
