[0002] During the construction of high-rise buildings, scaffolding needs to be erected around the exterior walls of the building before the construction of the upper structure can be carried out. The scaffolding on the bottom floors can be directly erected on the ground. When constructing high floors, the scaffolding needs to be erected on the cantilevered steel beams on the upper floors.

[0003] However, the existing cantilever steel beam is fixed to the outer wall by expansion bolts and nuts. When a scaffold is built on the cantilever steel beam, the cantilever steel beam will be overloaded, which will cause the expansion bolts to separate from the outer wall. This method of fixing the cantilever steel beam is not very safe, and the bottom of the cantilever steel beam is in a suspended state, resulting in a small bearing capacity of the entire cantilever steel beam, which is not conducive to the cantilever steel beam supporting the scaffold.

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-8 , the utility model provides a technical solution: a temporary fixing device for a cantilevered steel beam, comprising an outer wall 1, a side plate 3 is attached to the outer side of the outer wall 1, and the outer wall 1 and the side plate 3 are fixedly connected by a fixing mechanism 2;

[0027] The end of the cantilevered steel beam 4 is clamped inside the side plate 3 near the top of the side plate 3, and the cantilevered steel beam 4 and the side plate 3 are fixedly connected by bolts. A supporting mechanism 5 is provided at the bottom of the cantilevered steel beam 4 and one side of the side plate 3;

[0028] The supporting mechanism 5 includes a first slot 502. The first slot 502 is opened at the bottom of the cantilever steel beam 4. The end of the first support rod 501 is clamped inside the first slot 502. The second support rod 503 is installed with an internal thread of the first support rod 501. The lower end of the second support rod 503 passes through the interior of the first support rod 501 and is located inside the second slot 504. The lower end of the second support rod 503 is clamped and connected with the second slot 504. The second slot 504 is opened on one side of the side panel 3.

[0029] A second nut 505 is nested and fixed on the outer wall of the second support rod 503, and a third nut 506 is nested and fixed on the outer wall of the first support rod 501. The first support rod 501 can be fixed by the wrench and the third nut 506, thereby facilitating the rotation of the second support rod 503 by the wrench and the second nut 505.

[0030] The fixing mechanism 2 includes a first through hole 201, the top and bottom of the side panel 3 are both provided with a first through hole 201, and the exterior wall 1 is provided with a second through hole 202. The ends of a U-shaped rod 203 are passed through the interior of the first through hole 201 and the second through hole 202. A first nut 204 is threadedly installed on the end of the U-shaped rod 203, and the first nut 204 is located on the inner side of the exterior wall 1. Two first nuts 204 are arranged at one end of the U-shaped rod 203, and the first nuts 204 are symmetrically distributed about the central axis of the U-shaped rod 203. There are two U-shaped rods 203 symmetrically distributed about the central axis of the side panel 3. Since the ends of the U-shaped rod 203 pass through the inside of the side panel 3 and the exterior wall 1, and the first nut 204 is on the inner side of the exterior wall 1, under the action of the U-shaped rod 203 and the first nut 204, the side panel 3 and the cantilever steel beam 4 can be stably fixed.

[0031] A reinforcing block 6 is attached to one side of the bottom of the cantilever steel beam 4. One side of the reinforcing block 6 is fixedly connected to one side of the side panel 3. The reinforcing block 6 is designed as a triangular structure. The design of the reinforcing block 6 increases the strength of the connection between the side panel 3 and the cantilever steel beam 4.

[0032] Two support mechanisms 5 are provided, and the space enclosed by the support mechanisms 5 , the side panels 3 and the cantilevered steel beam 4 is designed as a triangular structure. Since the triangular structure has stability, the cantilevered steel beam 4 can stably support the scaffolding under the action of the two support mechanisms 5 .

[0033] Working principle: When using the temporary fixing device for cantilevered steel beams, firstly, the side plate 3 is attached to the outside of the outer wall 1, and then the drill bit on the electric drill is used to penetrate the inside of the first through hole 201, and then the second through hole 202 is opened on the outer wall 1 with the drill bit. The other three second through holes 202 are opened on the outer wall 1 according to the above principle, and then the two ends of the U-shaped rod 203 are passed through the inside of the two first through holes 201 and the second through holes 202 at the top, and the first nut 204 is threadedly installed on the end of the U-shaped rod 203, so that one side of the first nut 204 is in close contact with the inner side of the outer wall 1, and the top of the side plate 3 is fixed, and the bottom of the side plate 3 is fixed according to the above principle;

[0034] The side panel 3 and the cantilever steel beam 4 are fixed together by bolts, and then the upper end of the first support rod 501 is clamped into the inside of the first clamping groove 502, and the third nut 506 is fixed with a wrench so that the first support rod 501 does not rotate, and then the second nut 505 and the second support rod 503 are rotated with another wrench. Since the second support rod 503 and the first support rod 501 are threadedly connected, the lower end of the second support rod 503 moves close to the second clamping groove 504, so that the second clamping groove 504 is clamped with the lower end of the second support rod 503, completing the fixation of the support mechanism 5. Based on the same principle, another support mechanism 5 is installed between the side panel 3 and the cantilever steel beam 4, so that the two support mechanisms 5 complete the support of the cantilever steel beam 4, thereby increasing the bearing capacity of the cantilever steel beam 4 and facilitating the cantilever steel beam 4 to support the heavier scaffolding.
