Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a building safety net support device. Background Technology

[0002] Construction safety netting scaffolding is one of the most crucial safety devices on construction sites. It plays a key role in ensuring the safety of workers at heights, preventing falling objects, and enhancing the stability and load-bearing capacity of the scaffolding structure. Construction safety netting scaffolding typically consists of the scaffolding body, scaffolding base, and connectors. The scaffolding body is the main structure supporting the safety netting; it must be strong enough to support the weight of the entire netting and any other forces that may be applied to it. The scaffolding base stabilizes the scaffolding body, ensuring its stability under various weather and working conditions. Connectors are the critical components that connect the scaffolding body and the base; they must be able to withstand high tensile and shear forces.

[0003] Publication No. "CN220522090U" discloses an installation bracket for a safety net, relating to the field of safety net installation and addressing the high risk associated with the installation and use of safety nets. It includes a set of support components installed parallel to the wall surface. Each support component includes a vertical rod and a diagonal brace. The vertical rod is vertically fixed to the wall, and the bottom end of the diagonal brace is rotatably connected to the bottom end of the vertical rod. A limiting component is provided in the middle of the vertical rod, corresponding to the middle of the diagonal brace, to limit the rotation range of the diagonal brace. This application improves the safety of safety net installation and use.

[0004] While the aforementioned utility model improves the safety of safety nets during installation and use, construction safety nets are exposed to the outdoor environment for extended periods, making them susceptible to aging and damage from ultraviolet radiation, chemical corrosion, and other natural factors. Since the support equipment cannot replace the nets, aging nets cannot be updated in a timely manner, significantly reducing their protective performance and increasing safety hazards at construction sites. Furthermore, because the nets cannot be replaced, maintenance personnel will find it difficult to effectively repair any problems such as damage or deformation. This not only affects the normal use of the nets but may also lead to greater safety hazards due to improper maintenance. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a construction safety net support device to solve the problem that construction safety nets are exposed to the outdoor environment for a long time and are easily affected by natural factors such as ultraviolet radiation and chemical corrosion, resulting in aging and damage. If the support device cannot replace the net, the aging net cannot be updated in time, and its protective performance will be greatly reduced, thereby increasing the safety hazards at the construction site.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A construction safety net support device includes a support column, a reinforcing column fixedly connected to opposite ends of the support column, a diagonal brace hinged to one end of the support column, a first limiting rod hinged to one end of the support column, a second limiting rod hinged to one end of the diagonal brace, the first limiting rod and the second limiting rod being hinged to each other, a first fixing rod fixedly connected to the upper end of the diagonal brace, a second fixing rod fixedly connected to the upper end of the support column, fixing seats fixedly connected to the outer sides of both the first and second fixing rods, a safety net body movably connected to opposite ends of the fixing seats, mounting grooves provided at opposite ends of the fixing seats, mounting seats symmetrically fixedly connected to both ends of the safety net body, fixing components symmetrically installed inside both ends of the mounting seats, and positioning components symmetrically installed at both ends of the mounting seats;

[0008] The fixing assembly includes a cavity, a first return spring, a movable plate, and a locking block. The mounting base has symmetrically formed cavities inside. A first return spring is symmetrically fixedly connected to one end of each cavity, and a movable plate is fixedly connected to the other end of the first return spring. The movable plate is slidably connected to the cavity. A locking block is fixedly connected to the end of the movable plate away from the first return spring. The end of the locking block away from the movable plate extends out of the side of the mounting base, and the end of the locking block near the fixing base is beveled. The mounting groove is inserted into the mounting base, and locking grooves are symmetrically formed at both ends inside the mounting groove. The other end of the locking groove passes through the fixing seat. The locking groove and the locking block are snapped together. An unlocking block is slidably connected inside the locking groove. The end of the unlocking block away from the locking block extends out of the side of the fixing seat. Limiting grooves are symmetrically opened at both ends inside the locking groove. Limiting blocks are symmetrically fixedly connected at both ends of the unlocking block. The limiting blocks and the limiting grooves are slidably connected. This allows for timely detection and replacement of damaged safety nets, ensuring that the safety nets play their due protective role at critical moments, effectively preventing falls from heights, and significantly reducing safety risks caused by safety net problems.

[0009] As a preferred technical solution, the positioning component includes an internal hole, a second return spring, and a positioning post. The mounting base has internal holes symmetrically opened at the top and bottom. The second return spring is fixedly connected to one end of the internal hole, and the positioning post is fixedly connected to the other end of the second return spring. The positioning post is slidably connected to the internal hole. The top of the positioning post is arc-shaped. The mounting groove has positioning slots symmetrically opened at the top and bottom. The positioning slots and positioning posts are snapped together. This ensures that the safety net body reaches a precise position on the mounting base, avoiding safety hazards caused by inaccurate installation. At the same time, it can effectively fix the safety net and prevent it from shaking or falling off under the action of external factors such as wind and construction vibration.

[0010] As a preferred technical solution, a through hole is opened at one end of the support column, and a pull rope is fixedly connected to the end of the diagonal brace near the support column. The other end of the pull rope passes through the through hole and is fixedly connected to a fixing block. The diameter of the fixing block is larger than the diameter of the through hole, and a handle is fixedly connected to the other end of the fixing block. By keeping the pull rope taut, a stable connection between the safety net and the support equipment can be ensured, preventing shaking or closure caused by external forces such as wind or construction vibration. This is crucial for ensuring the safety of personnel at the construction site.

[0011] In summary, this utility model has the following main advantages:

[0012] In this invention, firstly, the mounting base at one end of the safety net body is inserted into the mounting groove at one end of the fixed base, so that the mounting base and the mounting groove are connected. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the moving plate to compress the first return spring. The locking block retracts into the cavity. Then, when the locking block moves to the locking groove, the first return spring resets, the moving plate rebounds, and the locking block pops out. The locking block and the locking groove are locked together, completing the installation of the safety net. This allows for the timely detection and replacement of damaged safety nets, ensuring that the safety net plays its due protective role at critical moments, effectively preventing falls from heights, and significantly reducing the safety risks caused by safety net problems.

[0018] Example

[0019] refer to Figures 1 to 4 This embodiment of a building safety net support device includes a support column 1, a reinforcing column 2 fixedly connected to the opposite end of the support column 1, a diagonal brace 3 hinged to one end of the support column 1, a first limiting rod 4 hinged to one end of the support column 1, a second limiting rod 5 hinged to one end of the diagonal brace 3, the first limiting rod 4 and the second limiting rod 5 being hinged to each other, a first fixing rod 6 fixedly connected to the upper end of the diagonal brace 3, a second fixing rod 7 fixedly connected to the upper end of the support column 1, fixing seats 8 fixedly connected to the outer sides of both the first fixing rod 6 and the second fixing rod 7, a safety net body 16 movably connected to the opposite end of the fixing seats 8, mounting grooves 9 being provided on the opposite ends of the fixing seats 8, mounting seats 10 symmetrically fixedly connected to both ends of the safety net body 16, fixing components 11 symmetrically installed inside both ends of the mounting seats 10, and positioning components 21 symmetrically installed at both ends of the mounting seats 10;

[0020] The fixing assembly 11 includes a cavity 111, a first return spring 112, a movable plate 113, and a locking block 114. The mounting base 10 has symmetrically arranged cavities 111 inside. The first return spring 112 is symmetrically fixedly connected to one end of each cavity 111, and the movable plate 113 is fixedly connected to the other end of the first return spring 112. The movable plate 113 is slidably connected to the cavity 111. The locking block 114 is fixedly connected to the end of the movable plate 113 away from the first return spring 112. The end of the locking block 114 away from the movable plate 113 extends out of the side of the mounting base 10. The end of the locking block 114 near the fixing base 8 is beveled. The mounting groove 9 is inserted into the mounting base 10, and locking grooves 114 are symmetrically arranged at both ends inside the mounting groove 9. 2. The other end of the locking groove 12 passes through the fixing seat 8. The locking groove 12 and the locking block 114 are snapped together. First, the mounting seat 10 at one end of the safety net body 16 is inserted into the mounting groove 9 at one end of the fixing seat 8, so that the mounting seat 10 and the mounting groove 9 are inserted. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 114, so that the locking block 114 drives the moving plate 113 to compress the first return spring 112. The locking block 114 retracts into the cavity 111. Then, when the locking block 114 moves to the locking groove 12, the first return spring 112 returns to its original position, and the moving plate 113 rebounds, causing the locking block 114 to pop out. The locking block 114 and the locking groove 12 are snapped together and fixed, thus completing the installation of the safety net.

[0021] refer to Figure 3An unlocking block 13 is slidably connected inside the locking groove 12. The end of the unlocking block 13 away from the locking block 114 extends out of the side end of the fixing seat 8. Limiting grooves 15 are symmetrically opened at both ends inside the locking groove 12. Limiting blocks 14 are symmetrically fixedly connected at both ends of the unlocking block 13. The limiting blocks 14 and the limiting grooves 15 are slidably connected. Pushing the unlocking block 13 causes it to slide inside the locking groove 12. At the same time, the limiting blocks 14 slide inside the limiting grooves 15. The unlocking block 13 pushes the locking block 114, causing the locking block 114 to drive the moving plate 113 to compress the first reset spring 112. The locking block 114 retracts into the cavity 111, and the locking block 114 and the locking groove 12 are no longer engaged. Then, the safety net body 16 is pulled outward to make the mounting seat 10 and the mounting groove 9 no longer inserted. The safety net is then removed from one end of the fixing seat 8, completing the disassembly of the safety net.

[0022] refer to Figure 4 The positioning component 21 includes an internal hole 211, a second return spring 212, and a positioning post 213. The mounting base 10 has internal holes 211 symmetrically formed at its upper and lower ends. One end of the internal hole 211 is fixedly connected to the second return spring 212, and the other end is fixedly connected to the positioning post 213. The positioning post 213 is slidably connected to the internal hole 211. The top of the positioning post 213 is arc-shaped. The mounting groove 9 has symmetrical positioning grooves 22 formed at its upper and lower ends. The positioning grooves 22 are engaged with the positioning post 213. First, insert the mounting base 10 at one end of the safety net body 16 into the mounting groove 9 at one end of the fixing base 8, so that the mounting base 10 and the mounting groove 9 are connected. During the insertion process, the squeezing force applies pressure to the arc surface of the positioning post 213, so that the positioning post 213 compresses the second return spring 212 and the positioning post 213 retracts into the inner hole 211. Then, when the positioning post 213 moves to the positioning groove 22, the second return spring 212 returns to its original position, the positioning post 213 pops out, and the positioning post 213 is locked and fixed to the positioning groove 22.

[0023] refer to Figure 1 One end of the support column 1 has a through hole 20. The end of the diagonal brace 3 near the support column 1 is fixedly connected to a pull rope 17. The other end of the pull rope 17 passes through the through hole 20 and is fixedly connected to a fixing block 18. The diameter of the fixing block 18 is larger than the diameter of the through hole 20. The other end of the fixing block 18 is fixedly connected to a handle 19. Pulling the pull rope 17 causes the diagonal brace 3 to move closer to the support column 1, so that the safety net body 16 is closed to the minimum state. At the same time, the pull rope 17 is wrapped around the outside of the fixing block 18, which can fix the safety net body 16 in the minimum state.

[0024] Operating principle and advantages: First, insert the mounting base 10 at one end of the safety net body 16 into the mounting groove 9 at one end of the fixing base 8, so that the mounting base 10 and the mounting groove 9 are connected. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 114 and the arc-shaped surface of the positioning post 213, so that the positioning post 213 compresses the second return spring 212. The positioning post 213 retracts into the inner hole 211. Then, when the positioning post 213 moves to the positioning groove 22, the second return spring... Spring 212 resets, positioning pin 213 pops out, positioning pin 213 engages with positioning groove 22 and is fixed, so that locking block 114 drives moving plate 113 to compress first reset spring 112, locking block 114 retracts into cavity 111, and then when locking block 114 moves to locking groove 12, first reset spring 112 resets, moving plate 113 rebounds and drives locking block 114 to pop out, locking block 114 engages with locking groove 12 and is fixed, completing the installation of safety net;

[0025] This invention can promptly detect and replace damaged safety nets, ensuring that the safety nets play their due protective role at critical moments, effectively preventing falls from heights, and significantly reducing safety risks caused by safety net problems.
