Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a triangular cantilever support frame for temporary infrastructure protection. Background Art
[0002] When constructing or decorating the main body of the exterior wall of a high-rise building, for the need of safety protection, a cantilever scaffold is usually constructed on the periphery of the building. In the existing cantilever scaffold, one end of an I-beam is horizontally extended into the floor, and the part of the I-beam extending into the floor is fixed to the ground by a tie rod or a U-ring. After the I-beam is fixed, a scaffold structure is made on the suspended part of the I-beam. Due to the lack of a support structure for the suspended part of the I-beam, when the I-beam is unevenly stressed or affected by external forces, there is a risk of tipping over, which may trigger a series of safety accidents and pose a serious threat to the personal safety and operation progress of the construction site. Therefore, a triangular cantilever support frame for temporary infrastructure protection is proposed. Content of the Utility Model
[0003] The purpose of the utility model is to solve any of the above technical problems, and thus a triangular cantilever support frame for temporary infrastructure protection is proposed, including an I-beam. A cross bar is fixed to the bottom of the I-beam, and a boss is arranged on the cross bar. The boss is fixedly clamped with the bottom of the I-beam. An inclined bar is further arranged at the bottom of the cross bar, and the inclined bar is arranged obliquely.
[0004] Further, a column is arranged on one side of the cross bar and the inclined bar for connection, and a reinforcing bar is arranged on the other side of the cross bar and the inclined bar.
[0005] Further, the column is fixed to the cross bar and the inclined bar by a welding process, and the reinforcing bar is also fixed to the cross bar and the inclined bar by a welding process.
[0006] Further, flange seats are arranged on one side of the cross bar and the inclined bar, and screw holes are arranged at the four corners of the flange seats.
[0007] Further, the boss is provided with a clamping groove, and the boss is fixedly clamped to the bottom of the I-beam through the clamping groove.
[0008] Beneficial Effects: By arranging a boss on the cross bar, the boss is fixedly clamped to the bottom of the I-beam. The cross bar is fixed to the exterior wall of the building through a flange seat on one side, and an inclined bar and a reinforcing bar are arranged at the bottom of the cross bar to support it. Through the cooperation of the cross bar and the inclined bar, the suspended part of the I-beam can be effectively supported to prevent it from tipping over. Description of the Drawings

To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.
[0015] Next, a triangular cantilever support frame for temporary infrastructure protection according to an embodiment of the present utility model will be described with reference to the accompanying drawings, as Figure 1 and Figure 2 shown. The triangular cantilever support frame for temporary infrastructure protection includes an I-beam 1, and is characterized in that: a cross bar 2 is fixed to the bottom of the I-beam 1, a boss 7 is provided on the cross bar 2, and the boss 7 is fixedly clamped with the bottom of the I-beam 1. A diagonal bar 3 is also provided at the bottom of the cross bar 2, and the diagonal bar 3 is inclined.
[0016] Preferably, a column 5 is provided on one side of the cross bar 2 and the diagonal bar 3 for connection, and a strengthening bar 4 is provided on the other side of the cross bar 2 and the diagonal bar 3.
