Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a protective net structure for building engineering. Background Technology

[0002] In the field of construction engineering, safety net structures are indispensable and important facilities for ensuring construction safety. Construction processes involve numerous hazards, such as falling objects and accidental falls. Safety nets effectively intercept and buffer these dangers, providing reliable safety protection for construction workers and the surrounding environment. As the scale and complexity of construction projects continue to increase, higher requirements are being placed on the performance and ease of installation of safety net structures.

[0003] The reference patent is titled "A Safety Net Structure for Construction Engineering" (Publication No. CN212053870U). This safety net structure for construction engineering enhances the stability of the safety net body during use by setting up columns and guard rods. With the cooperation of placement slots, through slots, insertion rods, and return springs, when it is necessary to disassemble the entire safety net body, the insertion rod is pulled in the direction of the hand pull block. At this time, the return spring is compressed, thereby causing the insertion rod to move away from the insertion hole, and then the guard rod can be removed from the inside of the placement slot, thus realizing the disassembly of the safety net body.

[0004] Based on the aforementioned patent, most traditional protective nets rely solely on the toughness of their own material to resist impacts, lacking an effective energy conversion and dissipation mechanism. When subjected to a strong impact, the protective net cannot disperse and dissipate the energy generated by the impact in a timely manner, causing a large amount of impact force to act directly on the net itself and the supporting structure. This easily leads to deformation, damage, or even loss of protective function, failing to provide reliable protection for construction projects and greatly increasing the risk of damage to buildings and surrounding facilities caused by impacts. Utility Model Content

[0005] The purpose of this invention is to provide a protective net structure for building construction to address the aforementioned shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective net structure for construction projects, comprising a protective net, and further comprising:

[0007] Support frames are installed on both sides of the protective netting;

[0008] The sliding rod is slidably installed inside the support frame and connected to the side of the protective net. When the protective net is hit by an external object, the sliding rods on both sides of the protective net slide along the inside of the support frame. The sliding rod drives the friction roller located inside the support frame to rotate through the transmission component 1 installed on the top of the support frame. The friction roller and the pressure plate slidably installed inside the support frame rub against each other. At the same time, the transmission component 1 pushes the pressure plate towards the friction roller through the transmission component 2 connected to it.

[0009] As a further description of the above technical solution: the support frame includes two sets of vertical rods, and a cavity block and a bottom block are fixed at the upper and lower ends of the vertical rods respectively. The upper surface of the bottom block is provided with a sliding groove for the sliding rod to slide, and the top of the sliding rod extends into the cavity block and slides with it.

[0010] As a further description of the above technical solution: the transmission component includes a rack slidably disposed inside the cavity block, one end of the rack being fixed to a slide rod, and the other end extending to the outside of the cavity block. A gear that meshes with the rack is also rotatably installed inside the cavity block, and the lower end of the axle on the gear is connected to a friction roller.

[0011] As a further description of the above technical solution: the transmission component two includes an L-shaped connecting rod connected to the rack, the L-shaped connecting rod slides horizontally against the front groove of the cavity block and a guide strip is fixed at its end, the front end of the pressure plate is fixed with a guide groove block, the guide groove block is provided with a continuous straight groove and an inclined groove, and the guide strip slides along the inside of the straight groove and the inclined groove.

[0012] As a further description of the above technical solution: the pressure plate is in contact with the two sets of vertical rods, and the protrusions provided on the inner side of the vertical rods cooperate with the grooves on both sides of the pressure plate, so that the pressure plate slides directionally along the inner side of the vertical rods.

[0013] As a further description of the above technical solution: the contact surfaces of both the friction roller and the pressure plate are made of rubber, and a spring is connected between the slide rod and the inner wall of one side of the cavity block.

[0014] In the above technical solution, the protective net structure for building engineering provided by this utility model has the following beneficial effects:

[0015] 1. The protective netting structure of this building project, when impacted by external objects, features a unique transmission structure that causes the slide bar to drive the rack to slide, which in turn drives the gear to rotate, causing the friction roller to rotate. At the same time, it pushes the pressure plate to move towards the friction roller. The rubber contact surfaces of the two rub against each other, effectively converting the energy generated by the impact into frictional heat energy, greatly reducing the impact force on the protective netting, providing a reliable protective barrier for the building project, and reducing the risk of damage to the building and surrounding facilities caused by external object impacts.

[0016] 2. The protective netting structure of this construction project can automatically adjust the degree of buffering according to the impact force of external objects. When the impact force is small, the guide strip slides only inside the straight groove of the guide block, the pressure plate moves relatively little towards the friction roller, and the squeezing force and friction between the pressure plate and the friction roller are small. This can appropriately buffer small impacts without causing unnecessary energy loss due to excessive buffering. When the impact force is large, the guide strip slides from the straight groove into the inclined groove, which increases the amount of pressure plate moving towards the friction roller, increases the squeezing force between the pressure plate and the friction roller, and the friction also increases, thus more effectively consuming the impact energy.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figures 1-4 This utility model embodiment provides a technical solution for a protective net structure in building engineering: it includes a protective net 1, and further includes:

[0026] Support frame 2 is installed on both sides of protective netting 1;

[0027] The sliding rod 3 is slidably mounted inside the support frame 2 and connected to the side of the protective net 1. When the protective net 1 is impacted by an external object, the sliding rods 3 on both sides of the protective net 1 slide along the inside of the support frame 2. The sliding rod 3 drives the friction roller 5 located inside the support frame 2 to rotate through the transmission component 4 installed on the top of the support frame 2. The friction roller 5 and the pressure plate 6 slidably mounted inside the support frame 2 rub against each other. At the same time, the transmission component 4 pushes the pressure plate 6 towards the friction roller 5 through the transmission component 7 connected to it. When the protective net 1 is impacted by an external object and causes displacement, the sliding rod 3 slides on the track inside the support frame 2. This sliding is transmitted to the friction roller 5 through the transmission component 4 to make it rotate. At the same time, the transmission component 7 converts the sliding of the sliding rod 3 into the power to push the pressure plate 6 closer to the friction roller 5, preparing for subsequent buffering.

[0028] In another embodiment of the present invention, preferably, the support frame 2 includes two sets of vertical rods 21, and the upper and lower ends of the vertical rods 21 are respectively fixed with a cavity block 22 and a bottom block 23. The upper surface of the bottom block 23 is provided with a groove for the sliding rod 3 to slide, and the top of the sliding rod 3 extends into the cavity block 22 and slides with it. This structure of the support frame 2 provides a stable sliding track for the sliding rod 3. The groove on the bottom block 23 supports and guides the bottom of the sliding rod 3, and the cavity block 22 accommodates the top of the sliding rod 3 and ensures that it can slide smoothly.

[0029] In another embodiment of the present invention, preferably, the transmission component 4 includes a rack 41 slidably disposed inside the cavity block 22. One end of the rack 41 is fixed to the slide rod 3, and the other end extends to the outside of the cavity block 22. A gear 42 that meshes with the rack 41 is also rotatably mounted inside the cavity block 22. The lower end of the axle on the gear 42 is connected to the friction roller 5. When the slide rod 3 slides, it drives the rack 41 to slide inside the cavity block 22. The meshing relationship between the rack 41 and the gear 42 converts the linear motion into the circular motion of the gear 42, which in turn drives the friction roller 5 to rotate through the axle.

[0030] In another embodiment of this utility model, preferably, the transmission component 2 7 includes an L-shaped connecting rod 71 connected to the rack 41. The L-shaped connecting rod 71 slides horizontally against the front groove of the cavity block 22 and a guide strip 72 is fixed at its end. A guide groove block 73 is fixed at the front end of the pressure plate 6. The guide groove block 73 is provided with a continuous straight groove and an inclined groove. The guide strip 72 slides along the inside of the straight groove and the inclined groove. The pressure plate 6 is in contact with two sets of vertical rods 21, and the protrusions provided on the inner side of the vertical rods 21 cooperate with the grooves on both sides of the pressure plate 6, so that the pressure plate 6 slides directionally along the inner side of the vertical rods 21. When the rack 41 slides, it drives the L-shaped connecting rod 71 to slide in the front groove of the cavity block 22. The guide strip 72 at the end of the L-shaped connecting rod 71 slides in the straight groove and the inclined groove of the guide groove block 73. This sliding trajectory pushes the pressure plate 6 to move directionally along the inner side of the vertical rods 21. The cooperation between the protrusions on the inner side of the vertical rods 21 and the grooves on both sides of the pressure plate 6 ensures the stability and directionality of the movement of the pressure plate 6.

[0031] In another embodiment of this utility model, preferably, the contact surfaces of both the friction roller 5 and the pressure plate 6 are made of rubber, and a spring 8 is connected between the slide rod 3 and the inner wall of one side of the cavity block 22. The rubber material has good elasticity and friction. When the friction roller 5 rotates and the pressure plate 6 approaches, the rubber contact surfaces abut against each other, which can more effectively convert the energy generated by the impact on the protective net 1 into frictional heat energy, playing a buffering and protective role. The spring 8 assists the slide rod 3 to reset.

[0032] When the protective net 1 is hit by an external object, the sliding rods 3 on both sides of the protective net 1 will slide along the inner side of the support frame 2. When the sliding rods 3 slide, they will drive the rack 41 fixed at one end to slide inside the cavity block 22. The other end of the rack 41 extends to the outside of the cavity block 22. Since the rack 41 meshes with the gear 42 rotatably installed inside the cavity block 22, the sliding of the rack 41 will drive the gear 42 to rotate. The lower end of the axle on the gear 42 is connected to the friction roller 5. The rotation of the gear 42 will drive the friction roller 5 to rotate.

[0033] As the rack 41 slides, the L-shaped connecting rod 71 connected to the rack 41 slides horizontally against the front groove of the cavity block 22. The guide strip 72 fixed at the end of the L-shaped connecting rod 71 also slides. The front end of the pressure plate 6 is fixed with a guide groove block 73. The guide groove block 73 is provided with a continuous straight groove and an inclined groove. The guide strip 72 slides from the straight groove into the inclined groove. During the sliding process of the guide strip 72, it pushes the pressure plate 6 towards the friction roller 5.

[0034] The friction roller 5 rotates and the pressure plate 6 moves towards the friction roller 5. The rubber contact surfaces of the two rub against each other, thereby consuming the energy of the protective net 1 when it is impacted, and playing a buffering and protective role.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
