[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1:

[0046] As Figures 1 - 3 shown, this embodiment provides a detachable steel structure safety rope fixing device, which includes a hoop body located outside the steel column and an adjustable component movably connected to the hoop body. A connecting ring is arranged on the outer side wall of the hoop body for fixing the safety rope.

[0047] In this embodiment, the hoop body includes a first hoop body 1 and a second hoop body 2, and the adjustable component includes a first connecting piece 3 and a second connecting piece 4 movably connected to the connection part of the first hoop body 1 and the second hoop body 2;

[0048] Specifically, the first hoop body 1 and the second hoop body 2 have the same structure, which are respectively L-shaped steel plates; first screw rods 11 are fixedly connected to the outer walls of the first hoop body 1 and the second hoop body 2.

[0049] The first connecting piece 3 and the second connecting piece 4 have the same structure, which are respectively L-shaped steel plates, and first through grooves 31 are respectively opened on their side walls.

[0050] Among them, since the first screw rod 11 can move within the first through groove 31, the first screw rods 11 of the first hoop 1 and the second hoop 2 are respectively passed through the corresponding first through grooves 31, so adjustment can be performed, that is, the length and width of the assembled device can be flexibly adjusted until the inner side walls of the first hoop 1 and the second hoop 2 abut against the steel column. At this time, the first connecting member 3 and the second connecting member 4 are fixedly connected to the outer walls of the first hoop 1 and the second hoop 2 through nuts, and the first connecting member 3 and the second connecting member 4 are located outside the first hoop 1 and the second hoop 2. During construction, the safety rope is fixed to the connecting ring 5 on the outer side walls of the first hoop 1 and the second hoop 2. After construction is completed, remove two nuts at the first connecting member 3, for example, remove the first connecting member 3, and then remove one of the nuts at the second connecting member 4. At this time, the first hoop member 1 can be removed, and the other second hoop member 2 and the second connecting member 4 can be removed together.

[0051] More specifically, a buffer layer such as a rubber gasket is also arranged on the inner side walls of the first hoop member 1 and the second hoop member 2, which plays a buffering role during the connection process.

[0052] In order to further maintain the stability of the device during assembly and use, support platforms 34 are respectively arranged at the bottoms of the first connecting member 3 and the second connecting member. In this embodiment, the support platforms of the first connecting member 3 and the second connecting member 4 face the opening side, which is convenient for supporting the first hoop 1 and the second hoop 2 during assembly.

[0053] The detachable steel structure safety rope fixing device provided in this embodiment, through the structural design of the first screw rod 11 and the first through groove 31, enables the connection positions of the two connecting members and the two hoop members to be adjustable, thereby forming an adjustable connection structure, that is, a structure with adjustable length and width respectively, to be suitable for sleeving steel columns of different specifications, and then sleeved on the steel column. Fix its length and width by tightening the nuts, and fix the safety rope through the connecting ring on the outer side wall to ensure the safety of steel structure construction.

[0054] Embodiment 2:

[0055] As Figures 4 - 6 shown, this embodiment provides a detachable steel structure safety rope fixing device, including a hoop located outside the steel column and an adjustable component movably connected to the hoop. A connecting ring is arranged on the outer side wall of the hoop for fixing the safety rope. The hoop includes a first hoop 1 and a second hoop 2, and the adjustable component includes a first connecting member 3 and a second connecting member 4 movably connected to the connection between the first hoop 1 and the second hoop 2;

[0056] Specifically, the first hoop 1 is L-shaped, and the second screw rods 12 are fixedly connected to its outer side wall respectively; the second hoop 2 is L-shaped, and a second through groove 21 is formed in its side wall. The first connecting member 3 and the second connecting member 4 have the same structure and are both L-shaped. A third through groove 32 is formed in one side wall thereof, and a third screw rod 33 is fixedly connected to the outer side of the other side wall.

[0057] Since the second screw rod 12 can move within the third through groove 32 and the third screw rod 33 can move within the second through groove 21, the second screw rod 12 is inserted into the corresponding third through groove 32 and the third screw rod 33 is inserted into the corresponding second through groove 21 to adjust the length and width of the assembled device; after the size adjustment is in place, the first connecting member 3 and the second connecting member 4 are fixedly connected to the outer wall of the first hoop 1 and the inner wall of the second hoop 2 through nuts. That is, at this time, the first hoop 1 is located inside the first connecting member 3 and the second connecting member 4, and the second hoop 2 is located outside the first connecting member 3 and the second connecting member 4.

[0058] To further maintain the stability of the device during assembly and use, support platforms 34 are respectively arranged at the bottoms of the first connecting member 3 and the second connecting member. In this embodiment, the support platform on the side of the first connecting member 3 close to the first hoop 1 is located at its inner bottom, and the support platform on the side close to the second hoop 2 is located at the bottom outside the first connecting member, that is, the bosses on the two sides of the first connecting member are respectively located inside and outside it, which is convenient for respectively supporting the first hoop 1 located inside it and the second hoop 2 located inside it during assembly.

[0059] For the detachable steel structure safety rope fixing device provided in this embodiment, when in use, the two ends of the first hoop 1 are respectively connected to the first connecting member 3 and the second connecting member 4, and then placed on the side of the steel column. At this time, the second hoop is assembled. After adjusting the positions of the screw rods in their respective corresponding through grooves according to the size of the steel column, nuts are used for fixation. After use, first remove the second hoop 2, and then loosen the positions of the first connecting member 3 and the second connecting member 4 on the first hoop 1, and the first hoop 1, the first connecting member 3 and the second connecting member can be removed together.

[0060] Embodiment Three:

[0061] For the detachable steel structure safety rope fixing device provided in this embodiment, when the hoop is a frame-shaped hoop 6, the adjustable component includes a rotating support bracket 7 rotatably connected to the side wall of the frame-shaped hoop 6.

[0062] Specifically, as Figures 7 - 12 shown, the frame-shaped hoop 6 is a frame structure, and at least one threaded hole 601 is formed in each side wall. In this embodiment, the frame-shaped hoop 6 is a square frame body, and two threaded holes 601 are formed in each of its four side walls.

[0063] In practical applications, the frame-shaped hoop body 6 may be an integral structure, such as Figure 7 , Figure 8 , Figure 10 As shown, this structure is suitable for the situation that the frame hoop body can be directly inserted from the end of the steel column.

[0064] The frame structure in this embodiment can also adopt a combined structure. Specifically, Figure 11 , Figure 12 As shown, the frame-type hoop body 6 includes a U-shaped frame body 61 and a sealing plate body 62. A connecting ear 611 is arranged at the end of the U-shaped frame body 61. Through holes are respectively opened at corresponding positions of the connecting ear 611 and the sealing plate body 62. Bolts can be used to connect the U-shaped frame body 61 and the sealing plate body 62 to form a frame-type hoop body 6 surrounded by the outside of the steel column.

[0065] Furthermore, if Figure 9 As shown, the rotating bracket 7 includes a rotating rod 71 with a threaded outer wall, a top plate 72 is arranged at one end of the rotating rod 71, and a rotating head 73 is arranged at the other end, wherein the top plate 72 is located on the inner side of the frame-shaped hoop body 6, and the rotating head 73 is located on the outer side of the frame-shaped hoop body 6. The rotating head 73 is welded to one end of the rotating rod 71 or is threadedly connected to one end of the rotating rod 71. By twisting the rotating head 73, the screw rod 71 can be rotated, so that the top plate 72 is away from or close to the side wall of the frame-shaped hoop body 6. After the top plate 72 abuts against the steel column, the device can be tightly held on the steel column, thereby facilitating the fixing of the safety rope during the steel structure construction process.

[0066] The detachable steel structure safety rope fixing device provided in this embodiment can adjust the distance between the top wall and the steel column by rotating the rotating bracket, so that its top plate can abut against the outer wall of the steel column, thereby being able to adapt to steel columns of different specifications, and realize the device to hold the outer wall of the steel column tightly, and then fix the safety rope through the connecting ring of the outer wall, thereby ensuring the safety of steel structure construction.
