[0002] With the continuous development of social economy and the continuous improvement of construction level, all kinds of buildings have sprung up all over the country. The emergence of various buildings has greatly improved people's quality of life. In order to prevent unstable falling rocks from causing serious harm to people and vehicles during the construction process, various protective nets have acted as "safety guards". In the construction field, especially in places with dense pedestrians, a layer of protective net is usually surrounded on the outer layer of the building to prevent pedestrians from falling objects from high-rise buildings.

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1-4 As shown, the utility model is a protective net for building construction, comprising a mounting frame 1, and a quick disassembly mechanism 3 is arranged outside the mounting frame 1;

[0024] The quick disassembly and assembly mechanism 3 includes a U-shaped plate 5, and an L-shaped plate 6 is fixedly connected to the middle of the front and rear walls of the outer side of the U-shaped plate 5. The L-shaped plate 6 can provide space for the installation of the screw 8 and its front and rear side components. The screw 8 is threadedly connected to the middle of the L-shaped plate 6. The front and rear groups of screws 8 are rotatably connected to a block 9 at one end close to each other through a bearing 15. The bearing 15 is provided so that the block 9 will not be affected during the rotation of the screw 8. The block 9 can be driven to move forward and backward during the rotation of the screw 8. When the two groups of blocks 9 approach each other, they can apply inward pressure to the mounting rod 4 with the cooperation of the pressure inclined surface 10, thereby fixing the mounting rod 4 and the U-shaped plate 5. A pressure inclined surface 10 is provided on one side wall of the block 9 close to the mounting frame 1, and a card groove 7 is provided in the middle of the front and rear walls of the U-shaped plate 5. The inner side of the U-shaped plate 5 is slidably connected to the mounting rod 4.

[0025] Among them, the slots 7 are clearance-matched with the blocks 9 , and the two sets of screw rods 8 are fixedly connected with a torsion plate 11 at one end away from each other. The torsion plate 11 can reduce the difficulty of rotating the screw rods 8 , and the blocks 9 can move back and forth inside the slots 7 .

[0026] The middle part of the outer circumference of the screw rod 8 passes through and is rotatably connected to the middle part of the opening 14 . The opening 14 is arranged in the middle part of the limiting plate 12 . The screw rod 8 does not interfere with the limiting plate 12 during rotation.

[0027] Among them, the adjacent sides of the front and rear limit plates 12 are penetrated and slidably connected to the inner side of the limit groove 13, and the limit grooves 13 are respectively arranged on the upper and lower sides of the middle part of the L-shaped plate 6. The limit grooves 13 can limit the limit plates 12, so that the limit plates 12 will not deflect during the forward and backward movement.

[0028] Among them, the end of the limit plate 12 away from the torsion plate 11 is fixedly connected to the block 9, and the openings 14 are located in the middle between the two groups of limit grooves 13. The limit plate 12 can connect and fix the block 9, making the block 9 more stable during movement.

[0029] Among them, the installation rods 4 are located on the inner sides of the two groups of blocks 9, and the protection net body 2 is fixedly connected to the middle of the inner wall of the installation frame 1. The protection net body 2 is fixed to the installation frame 1. Fixing the installation frame 1 to the installation rods 4 can realize the protection net installation operation.

[0030] The U-shaped plates 5 are respectively fixedly connected to the upper and lower ends of the left and right walls of the outer side of the installation frame 1 , and the U-shaped plates 5 are clearance-matched with the installation rods 4 .

[0031] Working principle: When it is necessary to install the construction protection net, first insert the U-shaped plates 5 on the left and right sides of the installation frame 1 into the outside of the corresponding installation rod 4, adjust the position of the installation frame 1 up and down to reach the specified position, and then rotate the front and rear torsion plates 11. The rotation of the torsion plates 11 causes the screw rods 8 on both sides to rotate. During the rotation of the screw rods 8, they will move forward and backward in the middle of the L-shaped plate 6, so that the front and rear side blocks 9 are close to each other. During the process of the blocks 9 approaching each other, the limiting plate 12 and the limiting groove 13 cooperate to make the pressure inclined surface 10 of the block 9 always face the installation rod, so that during the process of the blocks 9 approaching each other, the pressure inclined surface 10 applies pressure to the installation rod 4 toward one side of the installation frame 1, thereby fixing the U-shaped plate 5 and the installation rod 4 to complete the installation operation of the protection net.
