The device provides construction workers with an easy-to-install and easy-to-disassemble revolving construction safety belt buckle when working on the edge of a high-rise building, thereby reducing the investment in manpower and material resources.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A revolvable safety belt buckle comprises a rod body, one end of the rod body is fixedly connected to a fixing buckle, the other end of the rod body is threadedly connected to a threaded rod, one end of the threaded rod away from the rod body is fixedly connected to a limiting block, and the materials of the rod body, the fixing buckle and the limiting block are arranged from the outside to the inside in order as an anti-oxidation layer, an anti-corrosion layer, a wear-resistant layer and a metal base layer.

[0010] Preferably, a mounting hole is provided on the rod body, an outer wall of the threaded rod is provided with an external thread, and an inner wall of the mounting hole is provided with an internal thread matching the external thread.

[0011] Preferably, the material of the anti-oxidation layer is resin-based paint.

[0012] Preferably, the anti-corrosion layer is made of polyurea coating.

[0013] Preferably, the wear-resistant layer is made of high manganese steel.

[0014] Preferably, the metal base layer is made of Q235 steel.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. Compared with driving expansion bolts into the wall, the safety belt buckle can be recycled, saving material costs.

[0017] 2. Compared with expansion bolts, seat belt buckles are easy to install and leave no traces of screw heads after use, saving manpower investment.

[0018] 3. Compared with the seat belt hanging point of ordinary structure, this seat belt hanging point has high tensile strength and stronger reliability.

[0019] In summary, this device provides construction workers with an easy-to-install, easy-to-disassemble, and recyclable construction safety belt buckle when working on the edge of a high-rise building, thereby reducing the investment in manpower and material resources.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 3 A revolvable safety belt buckle includes a rod body 1, one end of the rod body 1 is fixedly connected to a fixing buckle 2, the other end of the rod body 1 is threadedly connected to a threaded rod 4, a mounting hole 6 is opened on the rod body 1, the outer wall of the threaded rod 4 is provided with an external thread 5, the inner wall of the mounting hole 6 is provided with an internal thread 7 matching the external thread 5, and the end of the threaded rod 4 away from the rod body 1 is fixedly connected to a limiting block 3.

[0026] The device is threadedly connected to the limit block 3 through the rod body 1 passing through the concrete screw hole or other holes, and is fixed on the wall to provide a reliable hanging point for the safety belt; the device is made of Q235 steel, and after calculation of tensile strength and yield strength, it can withstand a weight of about 4722kg; the tension and bending moment borne by the device are transmitted to the perforated structure through the threaded rod 4.

[0027] Positioning drilling: Before construction, observe the location where adjacent work is required. If there are holes for tension screws in the adjacent area, no holes need to be drilled. If there are no holes for tension screws and no reliable safety belt hanging points, through holes need to be drilled.

[0028] Fixed point installation: Pass the hanging end through the wall and connect it to the fixed end with bolts at the other end. The bolt connection is stable and reliable. After the installation is completed, the construction workers will hang the safety belt in the ring for construction.

[0029] Dismantling and recycling: After the edge construction is completed, the fixing buckles will be dismantled for use at the next construction site.

[0030] The materials of the rod body 1, the fixing buckle 2 and the limit block 3 are, from the outside to the inside, an anti-oxidation layer 8, an anti-corrosion layer 9, a wear-resistant layer 10 and a metal base layer 11. The material of the anti-oxidation layer 8 is a resin-based paint, which plays a role in isolating oxygen; the material of the anti-corrosion layer 9 is a polyurea coating, which has excellent wear resistance, corrosion resistance and fast curing characteristics; the material of the wear-resistant layer 10 is a high manganese steel material with high hardness; the material of the metal base layer 11 is Q235 steel, which has moderate strength and good plasticity, toughness and welding performance.
