A tool-type bulletproof safety net system for construction

Abstract

This application relates to a tool-type bulletproof safety net system for construction, comprising triggers anchored to the wall, bolt hooks, and steel frame sockets. A triangular steel frame is inserted into the steel frame sockets, with an eight-hole insert assembly at the top of the triangular steel frame. The safety net's two ends are hooked into the eight-hole inserts by steel wire ropes; the other two ends are hooked onto bolt hooks on the wall. Above the safety net is a bulletproof net, suspended by two triggers anchored to the wall and connected to two eight-hole inserts. The four sides of the bulletproof net are elastic ropes. The triggers include a circular locking chord, a rectangular pull-out structure, and a trigger rope. One end of the trigger rope is connected to the rectangular pull-out structure, and the other end is connected to the center of the bulletproof net. An elastic rope is placed on the locking slot of the circular locking chord. When the trigger rope is taut, it pulls down the rectangular pull-out structure, causing the circular locking chord to rotate and the elastic rope to disengage from the locking slot. This application improves the speed and safety of installing and dismantling the safety net.

Description

Technical Field

[0001] This invention relates to the field of construction safety facilities, and in particular to a tool-type bulletproof safety hanging net system for building construction. Background Technology

[0002] In the construction industry, high-altitude operations still require personnel to work at heights. Safety nets are used to prevent people and objects from falling or to mitigate injuries from falling objects. During building construction, appropriate safety nets are installed to protect against objects falling from heights.

[0003] While there are many types and quantities of safety nets for building construction on the market, their structures have several drawbacks: assembly is relatively complicated, suspension connections are unstable, and the nets have a degree of elasticity, sometimes bouncing a person back after a fall, causing secondary injury. Furthermore, traditional safety nets are mostly constructed from steel pipes, safety nets, and wire ropes, making installation and disassembly complex, requiring many components, slow, and inconvenient for reuse. Installation also requires workers to climb scaffolding made of steel pipes, which is extremely dangerous. Summary of the Invention

[0004] To improve the turnover of protective nets and reduce the possibility of danger during installation and dismantling, this application provides a tool-type bulletproof safety net system for building construction.

[0005] This application provides a tool-type bulletproof safety suspension net system for building construction, which adopts the following technical solution:

[0006] A tool-type bulletproof safety net system for construction includes a bulletproof net, a safety net, an eight-hole insert plate, iron rings, steel wire ropes, elastic ropes, triggers, trigger ropes, bolt hooks, triangular steel frames, and steel frame support sockets.

[0007] The steel frame socket is anchored to the wall, and the triangular steel frame is inserted into the steel frame socket. The uppermost part of the triangular steel frame is an eight-hole socket assembly. A steel wire rope is hung on the eight-hole socket, and the safety net is hung on the steel wire rope with an iron ring.

[0008] The triangular steel frame and the steel frame socket form a triangle, with multiple steel pipes connecting the middle of the triangular steel frame.

[0009] The elastic net is suspended above the safety net, providing double-layer protection.

[0010] The elastic rope around the elastic net is always taut and hangs on the trigger.

[0011] The trigger is structurally stable and is anchored to the wall with bolts.

[0012] The elastic rope is hung on the trigger. The trigger rope pulls the rectangular pull structure, the circumferential retaining cord releases the elastic rope, and the elastic net contracts.

[0013] By adopting the above technical solution, when a person or object falls, it first comes into contact with the elastic net. The elastic net is forced to move the lower trigger rope, which in turn pulls the rectangular pull structure. The rectangular pull structure rotates, the circumferential retaining ring loses its support, and the elastic rope breaks free from its restraint and contracts, wrapping the falling person or object and causing it to fall onto the safety net.

[0014] Multiple buffers extend the buffer time for people, better absorb the impact energy of a person falling, and increase the safety of the hanging net; at the same time, because the elastic net wraps around the person, it can reduce the large reaction force on the person after the safety net is tightened, which could cause the person to bounce back and cause further injury.

[0023] The following is in conjunction with the appendix Figure 1-7This application will be described in further detail.

[0024] This application discloses a tool-type bulletproof safety hanging net system for building construction.

[0025] Reference Figure 1 and Figure 2 A tool-type bulletproof safety net system for construction includes a trigger 7 and bolt hooks 9 fixed to the wall, and a steel frame socket 10. An eight-hole insert plate 3 is fixed to one end of a triangular steel frame 11 away from the wall. The triangular steel frame 11 is a three-dimensional triangle composed of triangular steel pipes in the middle, improving the overall structural stability. Two triangular steel frames 11 are connected by a steel wire rope 5, with both ends inserted into the eight-hole insert plate 3. The front end of the safety net 2 is hung on the steel wire rope 5 with several iron rings 4, and the rear end is hung on a steel wire rope 5 with both ends connected to the bolt hooks 9. Both sides are hung on steel wire ropes 5, with the front ends of the steel wire ropes 5 inserted into the eight-hole insert plate 3 and the rear ends hung on the bolt hooks 9, ensuring overall safety and stability.

[0026] The upper end of the safety net 2 is suspended by the elastic net 1. The front end of the elastic net 1 is hung on the steel wire rope 5 together with the safety net 1. The rear end of the elastic net 1 is hung on the trigger 7. The trigger 7 is located at a certain distance above the bolt hook 9. When a person or object falls, it can quickly contract and wrap around the person or object.

[0027] Reference Figure 3 The upper hook of the trigger 7 has an elastic rope 6 hanging around the elastic net 1, and the lower rectangular pull structure 73 has a trigger rope 8 in the middle. The trigger rope 8 is a non-elastic rope, and the other end is tied to the elastic net 1.

[0028] Reference Figure 4 and Figure 5 When no object is acting on the elastic net 1, the elastic rope 6 is taut in the circumferential retaining ring 71 at the top of the trigger 7. Because the rectangular pull structure 73 and the metal rod 74 are fixed, preventing the circumferential retaining ring 71 from rotating, the structure is stable, and the elastic rope 6 remains taut in the retaining ring. When a heavy object falls onto the elastic net 1, the elastic net 1 experiences a downward force, causing the trigger rope 8 to move downwards. The other end of the trigger rope 8 pulls the rectangular pull structure 73, causing it to rotate around the first metal shaft 74. At this point, it can no longer prevent the circumferential retaining ring 71 from rotating around the second metal shaft 75. The elastic rope 6 is instantly released, and all the elastic ropes 6 relax simultaneously, rebounding from above to envelop the falling person or object, effectively preventing people or objects from bouncing off the safety net.

[0029] Reference Figure 6During assembly, the upper part of the steel frame socket 10 is welded to the triangular steel frame 11, and the lower part of the steel frame socket is fixed to the wall by bolts 103. After the triangular steel frame 11 is assembled on the ground, it is directly lifted to the steel frame socket 10 by a tower crane or crane. The steel plate 101 is inserted into the limiting hole of the socket, and the bolts 102 are tightened to complete the installation. The tool-type safety net reduces the danger of manual installation and improves the turnover of the safety net.

[0030] Reference Figure 7 The eight-hole insert plate 3 at the top of the triangular steel frame 11 allows for easy and quick installation of the wire rope 5, safety net 2, and elastic net 1 onto the triangular steel frame.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
