Description

Technical Field

[0001] The utility model relates to the technical field of safety nets, in particular to a building safety net. Background Technique

[0002] Building safety nets are applicable to various construction sites, especially high-rise buildings. They can be used for fully enclosed construction, effectively preventing the fall injuries of people and objects, preventing fires caused by electric welding sparks, reducing noise and dust pollution, and achieving the effects of civilized construction, environmental protection and city beautification.

[0003] During the construction process, building safety nets are often used in cooperation with scaffolding. When using a building safety net, its surrounding parts are connected to the scaffolding through devices such as hooks. When connecting the safety net with hooks, generally, multiple workers simultaneously pull and straighten both sides of the safety net first, and then fix the positions of the four corners. Such an installation method not only increases the labor intensity of the workers, but also reduces the subsequent installation efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a building safety net to solve the problems existing in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A building safety net, including a safety net body, further including:

[0006] Fixed plates are arranged on both sides of the back surface of the safety net body. An activity groove is opened on the surface of the fixed plate, and a screw rod is rotatably connected inside the activity groove. An activity block is threadedly connected to the surface of the screw rod, and one end of the safety net body is fixed to the surface of the activity block. The outer end of the screw rod is fixedly connected with a torsion disc;

[0007] An arc-shaped plate hinged to one end of the back surface of the fixed plate. A limiting plate is hinged to one side of the back surface of the fixed plate. A spring is fixed inside the limiting plate, and the other end of the spring is fixed to the back surface of the fixed plate. A support block is fixedly connected to the back surface of the fixed plate.

[0008] Preferably, chutes are opened above and below the surface of the fixed plate, and sliders are slidably connected inside the chutes. One end of the safety net body is fixed to the inside of the sliders.

[0009] Preferably, a fastening bolt for fastening the scaffolding is threadedly connected inside the back surface of the arc-shaped plate.

[0010] Preferably, a soft pad is arranged on the outside of the support block, and the soft pad is made of rubber material.

[0011] Preferably, a limiting groove is formed in the inner side of one end of the arc-shaped plate, and the other end of the limiting groove is used in cooperation with the limiting plate.

[0012] Preferably, fixing holes are formed in the upper and lower sides of both sides of the surface of the safety net body, and the fixing holes on the upper and lower sides are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] After the fixing plates on both sides of the present utility model are fixed on the surface of the scaffolding, through the threaded connection between the surface of the screw and the thread inside the movable block, the safety net body can be driven to move outward, so that both ends of the safety net body can be pulled tight, thereby reducing the trouble of multiple workers manually tightening at the same time, and then improving the subsequent protection effect. At the same time, through the hinge connection between the arc-shaped plate and one end of the fixing plate, the arc-shaped plate can be driven to rotate to the back of the fixing plate, and by using the elastic force of the spring itself, the limiting plate can be driven to deflect at an angle, so that the limiting plate can facilitate the disassembly and assembly of the arc-shaped plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4As shown in the figure, a building safety net includes a safety net body 1. Fixed plates 2 are provided on both sides of the back surface of the safety net body 1. Activity grooves 16 are formed on the surfaces of the fixed plates 2. A screw rod 3 is rotatably connected inside the activity grooves 16. A movable block 4 is threadedly connected to the surface of the screw rod 3, and the surface of the movable block 4 is in fit with the inner wall of the activity groove 16. The surface of the movable block 4 is fixed to one end of the safety net body 1. A torsion disc 5 is fixedly connected to the outer end of the screw rod 3. One end of the back surface of the fixed plate 2 is hinged with an arc-shaped plate 8. One side of the back surface of the fixed plate 2 is hinged with a limiting plate 11. A spring 10 is fixed inside the limiting plate 11, and the other end of the spring 10 is fixed to the back surface of the fixed plate 2. A limiting groove 12 is formed inside one end of the arc-shaped plate 8, and the other end of the limiting plate 11 is in cooperation with the inside of the limiting groove 12, so that the other end of the limiting plate 11 can be clamped inside the limiting groove 12, thus facilitating the limiting and fixing of the arc-shaped plate 8. A support block 9 is fixedly connected to the back surface of the fixed plate 2. A soft pad 13 is arranged on the outside of the support block 9, and the soft pad 13 is made of rubber material, so that the friction between the support block 9 and the scaffolding can be increased, and the stability during fixing can be improved accordingly.

[0022] Sliding grooves 6 are formed above and below the surfaces of the fixed plates 2. Sliding blocks 7 are slidably connected inside the sliding grooves 6. The inside of the sliding blocks 7 is fixed to one end of the safety net body 1, so that the moving direction of the safety net body 1 can be limited and its stability during movement can be maintained, facilitating the subsequent better stretching and tensioning of the safety net body 1.

[0023] A fastening bolt 14 for fastening the scaffolding is threadedly connected inside the back surface of the arc-shaped plate 8. After the arc-shaped plate 8 is clamped on the surface of the scaffolding, with the rotation of the fastening bolt 14, the fixing effect between the scaffolding and the arc-shaped plate 8 can be improved.

[0024] Fixing holes 15 are formed above and below both sides of the surface of the safety net body 1, and the upper and lower fixing holes 15 are symmetrically distributed. After both ends of the safety net body 1 are tightened, external tools such as iron wires can pass through the fixing holes 15 and be tied to the scaffolding for fixing.

[0025] It should be noted that in this technical solution, technical features such as... should be regarded as prior art. For the specific structures, working principles, possible control methods, and spatial layout methods of these technical features, conventional selections in the art can be adopted, and this technical solution will not be further specifically elaborated.

[0026] Working principle: When in use, the support blocks 9 on the back of the left and right fixing plates 2 can be attached to the surface of the scaffolding. Then, rotate the arc plate 8 so that the arc plate 8 is located on the surface of the scaffolding column. Next, the elastic force of the spring 10 can be applied to drive the angle deflection of the limiting plate 11, so that the other end of the limiting plate 11 clamps and limits the arc plate 8. After that, rotate the fastening bolt 14 to further fasten between the arc plate 8 and the scaffolding column. Then, rotate the torsion disc 5 to drive the screw rod 3 to rotate, and at the same time drive the movable block 4 to move outward to pull the safety net body 1, so that the safety net body 1 can be tightened. When the safety net bodies 1 on the left and right sides are pulled and tightened to both sides, finally, tools such as iron wires can be passed through the fixing holes 15 and fixed to the scaffolding.
