[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example: Reference Figure 1-4 The device for fixing a safety rope for capping beam surface operation during the hoisting of a prefabricated beam slab is shown, comprising two cantilevered vertical pole brackets 1 fixed on the I-beam main beam and distributed up and down, a mounting column 2 is fixed on the inner bottom wall of the lower cantilevered vertical pole bracket 1, a vertical pole 3 is detachably fixed on the mounting column 2, and the upper end of the vertical pole 3 is fixedly passed through the upper cantilevered vertical pole bracket 1 and is installed with a plurality of disc bracket chucks 4;

[0031] It also includes a tension support body 5 and an auxiliary load-bearing body 6 fixed on the I-beam main beam;

[0032] The tension support body 5 is sleeved on the end of the upper cantilevered pole bracket 1 extending out of the I-beam main beam, and the tension support body 5 is used to provide an upward pre-tension for one end of the upper cantilevered pole bracket 1 extending out of the I-beam main beam;

[0033] The auxiliary load-bearing body 6 is clamped on the lower end of the cantilevered upright support 1 below, and the auxiliary load-bearing body 6 is used to strengthen the structural strength of one end of the cantilevered upright support 1 below extending out of the I-beam main beam and provide an upward supporting force.

[0034] Based on the above structure, a tension support body 5 is used to provide an upward pre-tension for the upper cantilever pole bracket 1, and an auxiliary load-bearing body 6 is used to provide an upward support force for the lower cantilever pole bracket 1, and enhance the structural strength of the lower cantilever pole bracket 1 extending from one end of the I-beam main beam, thereby enhancing the structural strength and weighing capacity of the two cantilever pole brackets 1, thereby avoiding deformation, bending and other problems of the cantilever pole bracket 1 when the buckle bracket chuck 4 bears a large amount of safety rope tension, thereby improving the stability of the safety rope fixing device for the cap beam surface operation during the construction process when the prefabricated beam slab is hoisted, and further improving safety.

[0035] The tension support body 5 includes a gusset plate 51, a first holding rod 52 and a second holding rod 53. The gusset plate 51 can be detachably mounted on the upper end of the I-beam main beam. The first holding rod 52 and the second holding rod 53 are both J-shaped rods.

[0036] Two first holding rods 52 are provided and fixed to both sides of the gusset plate 51 respectively, and the lower ends of the two first holding rods 52 are clamped to both sides of the lower end of the cantilevered upright support 1 above;

[0037] Two second holding rods 53 are also provided and are respectively fixed on both sides of the front end of the gusset plate 51. The two second holding rods 53 are clamped at the front end of the upper cantilevered pole bracket 1, and the lower ends of the two second holding rods 53 extend to the lower end of the upper cantilevered pole bracket 1 and are tightly pressed against the lower end of the cantilevered pole bracket 1.

[0038] The first holding rod 52 and the second holding rod 53 simultaneously provide an inclined upward pre-tension to the middle lower end and the front end of the upper cantilever upright support 1. When the upper cantilever upright support 1 bears load, the first holding rod 52 and the second holding rod 53 can share a certain pressure for the upper cantilever upright support 1 and transmit it to the I-beam main beam, thereby enhancing the structural strength of the end of the upper cantilever upright support 1 while reducing the probability of deformation of the upper cantilever upright support 1, so that the upper cantilever upright support 1 can bear a larger weight without being easily deformed and bent.

[0039] Among them, a cross brace 54 is fixed between the front ends of the two second holding rods 53, and one side of the cross brace 54 is pressed against the front end of the upper cantilever upright bracket 1. The cross brace 54 can connect the two second holding rods 53 and provide certain support to the front end of the upper cantilever upright bracket 1, thereby limiting the deformation of the front end of the upper cantilever upright bracket 1, thereby further improving the stability of the second holding rod 53 supporting the front end of the upper cantilever upright bracket 1, and further enhancing the load capacity of the front end of the upper cantilever upright bracket 1.

[0040] Among them, a tensioning bolt 7 is arranged on the gusset plate 51, and the thread at the lower end of the tensioning bolt 7 passes through the gusset plate 51 and is pressed against the upper end of the I-beam main beam. After the first holding rod 52 and the second holding rod 53 are sleeved on the upper cantilevered vertical pole bracket 1, an upward tension can be applied to the gusset plate 51 by screwing in the tensioning bolt 7, thereby applying an inclined upward pre-tension to the first holding rod 52 and the second holding rod 53, so that the gusset plate 51, the first holding rod 52 and the second holding rod 53 can be fixed in cooperation with the upper cantilevered vertical pole bracket 1, which is convenient for the hole-free installation of the tension support body 5.

[0041] The auxiliary load-bearing body 6 includes a fixing rod 61, a bearing plate 62 and a reinforcing support 63. The fixing rod 61 is fixed to the inner bottom wall of the I-beam main beam. Two fixing rods 61 are provided and respectively pressed against both sides of the cantilevered vertical pole bracket 1 below.

[0042] The front ends of the two fixing rods 61 are integrally formed with a load-bearing plate 62, which is a trapezoidal block with a horizontal upper cross-section. The end of the load-bearing plate 62 away from the I-beam main beam is thinner, and the upper surface of the load-bearing plate 62 is tightly pressed against the lower end of the cantilevered upright support 1 below, and the rear side of the load-bearing plate 62 is tightly pressed against the side wall of the front end of the I-beam main beam;

[0043] A reinforcing support 63 is integrally formed between the fixing rod 61 and the upper end of the load-bearing plate 62 , and the reinforcing support 63 is in an A-shape or a triangle.

[0044] By setting the fixing rod 61, the bearing plate 62 and the reinforcing support 63, the bearing plate 62 cooperates with the fixing rod 61 to provide an enhanced supporting force for the lower end of the cantilevered pole bracket 1 below, which can effectively enhance the bearing capacity of the portion of the cantilevered pole bracket 1 extending out of the I-beam main beam, thereby avoiding the cantilevered pole bracket 1 below being easily deformed when the buckle bracket chuck 4 carries a large amount of safety rope weight, thereby achieving the purpose of enhancing the structural strength and load capacity of the cantilevered pole bracket 1 below;

[0045] The reinforcing support 63 can further strengthen the structural stability of the fixing rod 61 and the load-bearing plate 62 , thereby further enhancing the reinforcing effect of the fixing rod 61 and the load-bearing plate 62 .

[0046] Among them, the front end of the load-bearing plate 62 is integrally formed with an upwardly extending lip 64, which covers the front end of the cantilevered upright bracket 1 below. The lip 64 can limit the deformation of the front end of the cantilevered upright bracket 1 below, thereby avoiding deformation of the front end of the cantilevered upright bracket 1 below and ultimately causing deformation of the overall structure.

[0047] Among them, the buckle bracket chuck 4 is rotatably connected to the vertical pole 3 through a connecting bearing 42, and a reinforcing rib 43 is fixed on the circumferential side of the connecting bearing 42. The upper end of the reinforcing rib 43 is in sliding contact with the lower end of the buckle bracket chuck 4, and the upper end of the buckle bracket chuck 4 is integrally formed with a reinforcing convex ring 41 surrounding the outer side of the connecting bearing 42. The rotating buckle bracket chuck 4 can unload the circumferential force generated by the safety rope on the vertical pole 3 when shaking, thereby avoiding deformation and damage at the connection between the buckle bracket chuck 4 and the vertical pole 3, further ensuring the stability of the connection between the buckle bracket chuck 4 and the vertical pole 3 during long-term use, avoiding the loss of function of the safety rope caused by deformation and falling off of the buckle bracket chuck 4, and the reinforcing convex ring 41 and the reinforcing rib 43 can also further enhance the structural strength of the buckle bracket chuck 4 itself, thereby making the load of the buckle bracket chuck 4 greater.

[0048] Working principle of the utility model: in daily use, after installing the cantilever pole bracket 1, the mounting column 2, the pole 3 and the buckle bracket chuck 4 in sequence, the staff only needs to clamp the tension support body 5 on the front end of the upper cantilever pole bracket 1, and fix the tension support body 5 by the tensioning bolt 7. At this time, the tension support body 5 applies an inclined upward pre-tension to the upper cantilever pole bracket 1, and the first holding rod 52 and the second holding rod 53 simultaneously provide an inclined upward pre-tension to the middle lower end and the front end of the upper cantilever pole bracket 1. When the upper cantilever pole bracket 1 is load-bearing, the first holding rod 52 and the second holding rod 53 can share a certain pressure for the upper cantilever pole bracket 1 and transmit it to the I-beam main beam, thereby enhancing the upper cantilever pole bracket 1 While increasing the structural strength of the end portion, the probability of deformation of the upper cantilevered pole bracket 1 is reduced, so that the upper cantilevered pole bracket 1 can bear a larger weight without being easily deformed and bent. Then, the auxiliary load-bearing body 6 is clamped at the lower front end of the lower cantilevered pole bracket 1, and the auxiliary load-bearing body 6 is fixed to the I-beam main beam. At this time, the load-bearing plate 62 and the fixing rod 61 cooperate to provide an enhanced supporting force for the lower end of the cantilevered pole bracket 1 below, which can effectively enhance the bearing capacity of the part of the cantilevered pole bracket 1 extending out of the I-beam main beam, thereby avoiding the cantilevered pole bracket 1 below being easily deformed when the buckle bracket chuck 4 carries a large amount of safety rope weight, thereby achieving the purpose of enhancing the structural strength and load capacity of the cantilevered pole bracket 1 below.

[0049] This enhances the structural strength and weighing capacity of the two cantilever vertical pole brackets 1, thereby preventing the cantilever vertical pole brackets 1 from being easily deformed, bent, etc. when the buckle bracket chuck 4 bears a large amount of safety rope tension, thereby improving the stability of the safety rope fixing device for the cap beam surface operation during the construction process when the prefabricated beam slab is hoisted, and further improving safety.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
