Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a safety protection net for building construction. Background Technology

[0002] With the rapid development of the construction industry, the number of high-rise buildings and complex structural construction scenarios is increasing, and construction safety has always been a core focus of the industry. Under the policy guidance of "safety first, prevention foremost, and comprehensive management," construction safety nets, as key facilities to prevent falls and falling objects, directly affect the level of safety management at construction sites in terms of their performance and applicability.

[0003] Construction safety nets are mainly based on planar barrier and impact buffering mechanisms. The nets usually use high-strength nylon nets, metal nets or steel wire nets as base materials, and are fixed to the building's external scaffolding, structural frame or edge openings by bolts, buckles, wires and other connectors to form a continuous planar protective barrier.

[0004] In existing technologies, when the main building structure shifts due to factors such as settlement and temperature deformation, the fixed protective netting is difficult to adjust synchronously, resulting in problems such as loosening, tearing, or detachment from the fixing point, creating a risk of protective failure. Therefore, a new type of construction safety protective netting is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a construction safety net, which aims to improve the problem that some protective nets in the prior art cannot be moved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A construction safety net includes a base body with moving mechanisms on both sides inside the base body. A protective component is fixedly connected to the top of the base body, and a vertical plate is fixedly connected to the outside of the protective component. An installation plate is fixedly connected to the bottom of the vertical plate, and a quick-connect mechanism is provided inside the installation plate. The moving mechanism includes a storage slot, which is opened on both sides of the base body. A support plate is fixedly connected between opposite sides inside the storage slot. A braking component for braking is provided inside the support plate. A spring is provided at the bottom of each support plate, and a rolling wheel is provided at the bottom of each spring. Two telescopic rods are provided near the top of each rolling wheel on both sides, and a telescopic cylinder is slidably connected to the top of each telescopic rod.

[0008] As a further description of the above technical solution:

[0009] The quick-connect mechanism includes a cylinder, the bottom of which is fixedly connected to the inside of the mounting plate, and a push plate is fixedly connected to the drive end of the cylinder. Rotating shafts are rotatably connected to both sides of the push plate.

[0010] As a further description of the above technical solution:

[0011] Each of the bracket plates has a threaded opening on its inner side, and a threaded post is threaded into the inner side of the threaded opening. A rotating handle is provided on the top of each threaded post.

[0012] As a further description of the above technical solution:

[0013] The top of the telescopic cylinder is fixedly connected to the bottom of the support plate, and the bottom of the base body has openings on both sides.

[0014] As a further description of the above technical solution:

[0015] The mounting plate has an installation opening inside, the rotating shaft is rotatably connected to a fixing plate on the outside, the fixing plate is rotatably connected to a fixing plate inside, the fixing plate is slidably connected to a connecting column on the outside, and the connecting column has a hole inside.

[0016] As a further description of the above technical solution:

[0017] The fixed plate is rotatably connected to a second rotating shaft inside, and the two outer ends of the second rotating shaft are rotatably connected to the inside of the mounting plate.

[0018] As a further description of the above technical solution:

[0019] The protective component includes a frame, and a mesh is provided inside the frame.

[0020] As a further description of the above technical solution:

[0021] Both sides of the frame are provided with connecting plates, and two upright plates are fixedly connected to the outside of the connecting plates. The bottom of each upright plate is provided with a mounting plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the threaded column is rotated within the threaded opening by rotating the handle. The threaded column then pushes against the rolling wheel connected to the spring, thereby enabling the rolling wheel to be pushed out for use. The buffer structure of the spring and telescopic rod can absorb the ground impact force during movement, preventing the protective net from tearing or parts from falling off due to violent shaking. At the same time, it reduces the pushing load on the operator, making the movement process smoother and more stable. This helps to assist personnel in transporting and moving goods, significantly saving manpower and providing convenience for personnel movement.

[0024] 2. In this utility model, by pushing the push plate to move upward inside the mounting plate, the rotating shafts on both sides of the push plate drive the fixing plate to rotate around the rotating shaft. Compared with the traditional bolt connection, the installation efficiency of fixing a single mounting plate to the connecting column is improved. The L-shaped snap-fit ​​structure can automatically align with the hole of the connecting column, reducing the on-site positioning requirements and reducing rework problems caused by manual alignment deviation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3An embodiment of this utility model provides a construction safety net, including a base body 1, with moving mechanisms provided on both sides inside the base body 1, a protective component fixedly connected to the top of the base body 1, a vertical plate 15 fixedly connected to the outside of the protective component, and an installation plate 16 fixedly connected to the bottom of the vertical plate 15. The vertical plate 15 is used to support the protective component and connect the installation plate 16. A quick connection mechanism is provided inside the installation plate 16, and the installation plate 16 is used to integrate the quick connection mechanism to achieve fixation with the building structure.

[0034] The moving mechanism includes storage slots 2, which are located on both sides of the base 1. Support plates 3 are fixedly connected between opposite sides of the storage slots 2. Braking components are installed inside the support plates 3. Springs 7 are installed at the bottom of each support plate 3. The springs 7 act as elastic buffers, absorbing impact when the rollers 8 contact the ground, reducing movement bumps, and providing a restoring force when stored. Rollers 8 are located at the bottom of each spring 7. Two telescopic rods 9 are installed near the top of each roller 8 on both sides. The storage slots 2 are used to store the rollers 8. When the protective net is fixed, the rollers 8 are hidden inside the base 1 to avoid affecting the stability of the protective net. The support plates 3 serve as the supporting frame for the moving mechanism, fixing the braking components and springs 7, and providing screw-in guidance for the threaded posts 5. The rollers 8, which carry the moving function of the protective net, are made of wear-resistant rubber with reinforced surface texture. Ground friction, telescopic cylinder 10 is slidably connected to the top of telescopic rod 9, telescopic rod 9 and telescopic cylinder 10 cooperate to form a guide structure to ensure vertical lifting and lowering of rolling wheel 8 and avoid deviation. Telescopic cylinder 10 provides a sliding track for telescopic rod 9 to limit the lateral displacement of rolling wheel 8. Each support plate 3 has a threaded opening 4 on its inner side. The threaded opening 4 is connected to a threaded post 5 by a threaded thread. The threaded opening 4 and threaded post 5 cooperate to form a threaded transmission mechanism to convert rotational force into vertical thrust. Each threaded post 5 is equipped with a rotating handle 6 on its top. The threaded post 5 is driven by the rotating handle 6 to press or release spring 7 and control the lifting and lowering state of rolling wheel 8. The top of telescopic cylinder 10 is fixedly connected to the bottom of support plate 3. Both sides of the bottom of base body 1 have a lower opening 11. The lower opening 11 is a channel for rolling wheel 8 to extend or retract. The opening size matches the outer diameter of rolling wheel 8 to ensure smooth lifting and lowering.

[0035] Reference Figure 1 , Figure 4 and Figure 5The quick-connect mechanism includes a cylinder 19, the bottom of which is fixedly connected to the inside of a mounting plate 16. A push plate 20 is fixedly connected to the drive end of the cylinder 19, and the cylinder 19 is used to push the push plate 20. Rotating shafts 21 are rotatably connected to the inside of both sides of the push plate 20. An installation port 17 is provided inside the mounting plate 16 for aligning with the connecting column 18 of the building structure and providing installation positioning. A fixing plate 23 is rotatably connected to the outside of the rotating shafts 21, and a fixing plate 24 is rotatably connected to the inside of the fixing plate 23. 3. Rotating shaft 21 is one of the rotation fulcrums of fixed plate 23, allowing fixed plate 23 to rotate around its axis. Push plate 20 is used to convert the thrust of cylinder 19 into the rotation driving force of fixed plate 23. Connecting column 18 is slidably connected to the outside of fixed plate 23. Holes are provided inside connecting column 18. Fixed plate 23 is rotated into the holes of connecting column 18 to form an L-shaped mechanical lock. Rotating shaft 22 is rotatably connected inside fixed plate 23. The two ends of rotating shaft 22 are rotatably connected to the inside of mounting plate 16.

[0036] The protective component includes a frame body 12, with a mesh 13 inside the frame body 12. The mesh 13 is made of high-strength composite fiber mesh. Connecting plates 14 are provided on both sides of the frame body 12. Two upright plates 15 are fixedly connected to the outside of the connecting plates 14. Mounting plates 16 are provided at the bottom of each upright plate 15.

[0037] Working principle: When the protective net needs to be moved, the operator rotates the handle 6 clockwise, causing the threaded post 5 to screw downwards into the threaded opening 4 of the support plate 3 fixed in the storage tank 2. The bottom end of the threaded post 5 gradually presses against the spring 7, forcing the spring 7 to compress. At the same time, it pushes the rolling wheel 8 to move downwards against the elastic force of the spring 7. The telescopic rod 9 gradually extends from the telescopic cylinder 10 until the rolling wheel 8 contacts the ground through the lower opening 11 at the bottom of the base body 1, lifting the base body 1 as a whole, so that the protective net is removed from the ground support and enters a movable state. After the rolling wheel 8 contacts the ground, the operator can push the protective net and adjust its position by rolling the rolling wheel 8. The combination structure of the spring 7 and the telescopic rod 9 can buffer the bumps during the movement and prevent the protective net from shaking violently. At the same time, the sliding guide effect of the telescopic rod 9 ensures that the rolling wheel 8 rises and falls vertically and prevents deviation.

[0038] The mounting plate 16 at the bottom of the upright plate 15 is aligned with the connection point of the building structure. The connecting column 18 is pre-fixed at the target connection position, and its internal hole is aligned with the mounting port 17 of the mounting plate 16. The cylinder 19 pushes the push plate 20 to move upward inside the mounting plate 16. The rotating shaft 21 on both sides of the push plate 20 drives the fixing plate 23 to rotate around the rotating shaft 22. Since the two ends of the rotating shaft 22 are fixed inside the mounting plate 16, the fixing plate 23 unfolds outward with the rotating shaft 22 as the center. Its outer end gradually gets into the hole of the connecting column 18, forming an L-shaped locking structure, which firmly connects the mounting plate 16 and the connecting column 18, and completes the rapid installation of the mesh 13 inside the frame 12 supported by the connecting plate 14.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
