Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a safety belt fixing device for shear walls. Background Technology

[0002] Construction sites are accident-prone locations with various fatal hazards, among which falls from heights account for a significantly higher proportion, consistently ranking high. When working near construction sites, workers must wear safety harnesses to ensure their safety. Construction safety harnesses include a safety harness strapped to the worker, a safety rope connecting the harness, and a hook for attaching the rope. Workers must secure the hook to a fixed object on site, which is often difficult to find suitable and safe.

[0003] Currently, the common method is to use metal expansion bolts to fix the safety belt hooks to the wall. However, these expansion bolts rely on friction after expansion to achieve a fixed position, which is not very reliable in terms of safety. Furthermore, they are not easy to retrieve after use, and removal is cumbersome. Another method is to directly drill a through hole in the wall, insert a long threaded rod into the hole, and secure it firmly with bolts on the outside. However, installing bolts on the outside of the wall remains difficult when the wall is adjacent to an exterior wall. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model designs a safety belt fixing device for shear walls, which solves the problem of the firmness of the safety belt hook anchor point and also enables quick installation and disassembly from the inside of the wall, greatly reducing the safety risks to operators.

[0005] This utility model provides a safety belt fixing device for shear walls, characterized in that it includes a main screw and a fixing pin. One end of the main screw is hinged to the middle of the fixing pin, and the other end of the main screw is threaded to a lifting eye nut. A locking nut is also threaded to the main screw. The length of the fixing pin and the outer diameter of the locking nut are both larger than the diameter of the mounting hole on the shear wall. One end of the fixing pin is connected to a recyclable steel wire rope.

[0006] Furthermore, one end of the main screw is provided with a radial groove, and the fixing pin is inserted into the groove and hinged to the main screw. When the fixing pin is rotated to be parallel to the axis of the main screw by pulling the retractable steel wire rope, the fixing pin can be completely embedded in the groove.

[0007] Furthermore, the groove is strip-shaped and communicates with the end of the main screw, and the fixing pin is plate-shaped.

[0008] Furthermore, the other end of the recovery wire rope is connected to the eye nut.

[0009] Furthermore, a wire rope fixing ring is threaded onto the lifting eye nut, and the other end of the retractable wire rope is connected to the wire rope fixing ring.

[0010] Compared with the prior art, the advantages of this utility model are: the device has the characteristics of simple structure, convenient operation, lightweight and easy to carry, and high safety, which provides great protection for the life safety of workers at high places and adjacent areas on construction sites. Attached Figure Description

[0011] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model;

[0012] Figure 2 This is an installation diagram of an embodiment of the present utility model. Detailed Implementation

[0013] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, the embodiment of this utility model includes a main screw 1 and a fixing pin 2. One end of the main screw 1 has a radially provided groove 6, and the fixing pin 2 is inserted into the groove 6, with its middle portion hinged to the main screw 1. When the fixing pin 2 rotates to be parallel to the main screw 1, the fixing pin 2 can be embedded in the groove 6. Preferably, the groove 6 is strip-shaped and communicates with the end of the main screw 1, and the fixing pin 2 is plate-shaped. The other end of the main screw 1 is threaded with a lifting eye nut 3, and a locking nut 4 is also threaded onto the main screw 1. The length of the fixing pin 2 and the outer diameter of the locking nut 4 are both larger than the diameter of the mounting hole on the shear wall.

[0015] To facilitate quick disassembly and reassembly of the safety belt securing device from the inside of the wall, one end of the securing pin 2 is connected to a retraction steel wire rope 5, and the other end of the retraction steel wire rope 5 is connected to the eye nut 3. By pulling the retraction steel wire rope 5, the securing pin 2 can be rotated to be parallel to the axis of the main screw 1. At this time, the securing pin 2 can be fully embedded in the groove 6, allowing the safety belt securing device to pass through the mounting hole in the shear wall. For easy storage, a steel wire rope securing ring 7 is threaded onto the eye nut 3, and the other end of the retraction steel wire rope 5 is connected to the steel wire rope securing ring 7.

[0016] During installation, rotate the fixing pin 2 until it is parallel to the main screw 1 and insert it into the groove 6. Then, insert the main screw 1 along with the retractable wire rope 5 into the shear wall mounting hole. Push the retractable wire rope 5 outward so that the fixing pin 2 stands upright at a 90° angle to the main screw 1. Tighten the locking nut 4. The locking nut 4 and the fixing pin 2 will firmly fix the main screw 1 to the mounting hole of the shear wall. During disassembly, first loosen the locking nut 4, then pull the fixing pin 2 flat using the retractable wire rope 5 to easily remove the entire safety belt fixing device from the shear wall mounting hole.
