[0003] In the current bent cap support pad stone construction, safety guardrails are used in design as edge safety protection during support pad stone construction to ensure the safety of operating personnel in high-altitude construction, thereby preventing high-altitude falling, and such safety protection requires a large number of guardrails and protective meshes, and the traditional bent cap safety guardrails have complex installation and removal processes, long cycle and high safety protection cost.

[0004] When operating personnel construct bent cap support pad stones, detachable safety protection facilities are used in combination with safety belts, so that workers can move back and forth and also ensure safe operation. SUMMARY

[0005] The utility model aims at reducing the safety risk of operating personnel falling from high altitude and ensuring the safety of operating personnel in high-altitude construction, and provides a detachable safety protection device for support pad stones, which is simple to install, safe, has high reusability, simple structure design, saves time and effectively reduces engineering cost.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: the safety protection device comprises a steel wire rope 3 fixing point, a steel frame and a anti-drop device 4.

[0007] First, embed threaded steel bars on both sides of the bent cap block as the fixing point of the steel wire rope 3; after the main beam is cured, customize the steel frame, which is composed of a "U"-shaped steel 1 and a connecting steel 1; use high-strength bolts 2 and high-strength nuts to fix and connect the steel frame; install the anti-drop device 4 on the "U"-shaped steel 1, and then pass the steel wire rope 3 through the embedded steel bar 5 and fix it.

[0008] Further, the threaded steel bar is φ16.

[0009] Further, the steel frame is made of Q235 steel material and is well treated against rust.

[0010] Further, the high-strength bolt 2 adopts M18.

[0011] The utility model has the advantages of:

[0012] Safety improvement: the device can greatly reduce the risk of high-altitude operation of the operating personnel through the preset steel frame and the installation of the anti-drop device 4, effectively improving the safety of the bent cap support cushion stone construction.

[0013] Construction efficiency improvement: the design of the embedded threaded steel bar and the steel frame simplifies the installation and disassembly process, greatly improving the construction efficiency.

[0014] Cost saving: the device uses Q235 steel, and can be reused, saving a large amount of material consumption, thereby reducing the construction cost.

[0015] Simple design and easy operation: the device is simple in design and easy to operate, and is easy for workers to accept and promote.

[0016] Environmentally friendly: since the device can be reused, the impact on the environment is reduced, meeting the environmental protection goal.

[0017] In summary, the utility model provides a simple, efficient, safe and economical high-altitude construction safety protection device, which is conducive to promoting the development of bent cap support cushion stone construction technology. BRIEF DESCRIPTION OF DRAWINGS

[0022] The utility model will be described in detail in combination with the drawings, and the technical scheme of the utility model embodiment will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0023] As shown in Figs. 1-3 The bent cap block steel bar formwork is installed, and Fig. 3Install φ16 threaded steel bars 30 cm inward from the outside at both ends of the block. After the cap beam block concrete is poured and cured, use a crane to remove the formwork while hoisting and assembling the steel frame's U-shaped steel 1 and connecting steel 1. Finally, secure them with M18 high-strength bolts 2 and M18 high-strength nuts. After ensuring that the steel frame is stable, install the anti-slip device 4 and wire rope 3 in sequence.
