Description

Technical Field

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

[0002] Construction safety netting is a specialized protective facility used on construction sites. It is typically woven from durable materials (such as high-density polyethylene, HDPE), possessing a certain level of strength and weather resistance. Its primary function is to act as a safety barrier, preventing personnel, tools, and other objects from falling from heights, while also reducing the adverse effects of the building's internal and external environment on construction operations.

[0003] Patent publication number CN222045163U4 proposes a protective net for construction projects, which mainly includes a protective net body and a connecting mechanism. The connecting mechanism consists of a connecting plate, a base frame, a sliding table, and a force-absorbing component. By setting the force-absorbing component, the impact force can be reduced when the protective net body is impacted, thereby reducing the damage caused by the impact force to the protective net body. This can effectively improve the service life of the protective net body, enhance the protective performance of the protective net body, and make the protective net body more practical.

[0004] However, when using protective nets, they are often damaged due to collisions or other reasons. Damaged protective nets need to be replaced in time to ensure the safety of the device during use. However, the aforementioned replacement by rotation requires the removal of multiple bolts, and the subsequent installation of the protective net requires tightening the net before screwing in the bolts, which is not convenient for a single person to operate and affects the efficiency of replacing the protective net. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a protective net for construction projects, which solves the problem that protective nets are often damaged due to collisions or other reasons during use. Damaged protective nets need to be replaced in a timely manner to ensure the safety of the device during use. However, the aforementioned rotational replacement requires the removal of multiple bolts, and the subsequent installation of the protective net requires tightening the net before screwing in the bolts, which is inconvenient for single-person operation and affects the efficiency of protective net replacement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a protective net for construction projects, comprising an installation frame, an installation bracket and an arc-shaped threaded pipe welded to the outer side of the installation frame, a support frame welded inside the installation frame, a limiting plate welded to the inner side of the installation frame, threaded rods welded to both ends of the limiting plate, a clamping plate inserted and installed above the limiting plate, a protective net body provided on the outer side of the limiting plate, and fixing rings engaged on both sides of the protective net body, and a connecting rod connected to the outer side of the arc-shaped threaded pipe.

[0007] The beneficial effects of this utility model are as follows: the fixing ring is sleeved on the plug rod on the limiting plate, and then installed on the upper part of the limiting plate through the clamping plate groove and the plug hole. The clamping plate is fixed by the threaded rod, nut and washer. The other side of the protective net body is fixed in the same way as above, which completes the installation of the device. When disassembling, only the nut on the threaded rod needs to be unscrewed. The above method allows a single person to replace the protective net body, ensuring the efficiency and effectiveness of the protective net replacement.

[0008] The fixing ring can effectively increase the strength of the connection point between the protective net body and the plug rod, and prevent the protective net body from separating from the plug rod due to pulling.

[0010] As a further improvement to the above technical solution: the mounting frame is provided with a sliding groove near the clamping plate, and the clamping plate and the mounting frame are connected by the sliding groove to form a locking and sliding mounting structure.

[0011] The beneficial effects of this improvement are: the position of the clamping plate can be limited and guided by the sliding groove, ensuring that the installation of the clamping plate is more convenient and accurate.

[0012] To increase the protection of the device:

[0013] As a further improvement to the above technical solution: the support frame and the mounting frame are integrated by welding.

[0014] The beneficial effects of this improvement are: the integrated welding design can ensure the connection strength between the support frame and the mounting frame, and the support frame can also increase the protective effect of the device.

[0015] To facilitate the installation of the protective netting body:

[0016] As a further improvement to the above technical solution: the limiting plate is welded with plug rods at equal intervals on the side near the threaded rod.

[0017] As a further improvement to the above technical solution: the clamping plate is provided with insertion holes at equal intervals.

[0018] The beneficial effects of this improvement are: the plug rod can pass through the fixing ring to limit the position of the protective net body, and then cooperate with the plug hole on the clamping plate to fix the position of the protective net body, thereby facilitating the installation of the protective net body.

[0019] To facilitate the connection between the connecting rod and the arc-shaped threaded tube:

[0020] As a further improvement to the above technical solution: the connecting rod and the arc-shaped threaded pipe are connected by a thread.

[0021] The beneficial effects of this improvement are: the threaded connection can ensure the connection strength between the connecting rod and the arc-shaped threaded pipe, and it can also facilitate the splicing of the installation frame and the installation frame.

[0022] To facilitate the rotation of the connecting rod:

[0023] As a further improvement to the above technical solution: the outer circumferential surface of the connecting rod is provided with protrusions.

[0024] The beneficial effects of this improvement are: the protrusion can increase the friction between the connecting rod and the palm, making it easier to connect the connecting rod to the arc-shaped threaded tube.

[0025] To ensure the position of the protective net body:

[0026] As a further improvement to the above technical solution: the limiting plate and the mounting frame are arranged in parallel to each other.

[0027] The beneficial effect of this improvement is that the parallel arrangement of the limiting plates and clamping plates can fix the position of the protective net body. Attached Figure Description

A clamping plate 22 is inserted and installed above the limiting plate 2. A protective net body 3 is provided on the outer side of the limiting plate 2, and fixing rings 31 are engaged on both sides of the protective net body 3. A connecting rod 4 is connected to the outer side of the arc-shaped threaded pipe 12. The fixing rings 31 are sleeved on the inserting rods on the limiting plate 2, and then connected by the clamping plate 2. 2. The sliding groove and the insertion hole are installed above the limiting plate 2. The clamping plate 22 is fixed by the threaded rod 21 in conjunction with the nut and washer. The other side of the protective net body 3 is fixed in the same way as above, thus completing the installation of the device. When disassembling, simply unscrew the nut on the threaded rod 21. The above method allows a single person to replace the protective net body 3, ensuring the efficiency and effectiveness of the replacement. The fixing ring 31 can effectively increase the strength of the connection point between the protective net body 3 and the insertion rod, preventing the protective net body 3 from detaching from the insertion rod due to pulling. The mounting frame 1 has a sliding groove near the clamping plate 22, and the clamping plate 22 and the mounting frame 1 are connected by a sliding groove. The sliding installation structure is formed by a sliding groove, which limits and guides the position of the clamping plate 22, ensuring more convenient and accurate installation. The support frame 13 and the mounting frame 1 are welded together, which ensures the connection strength between the support frame 13 and the mounting frame 1 and also increases the protective effect of the device. The limiting plate 2 has plug-in rods welded at equal intervals on the side near the threaded rod 21. The clamping plate 22 has plug-in holes at equal intervals. The plug-in rods can pass through the fixing ring 31 to limit the position of the protective net body 3, thereby cooperating with the plug-in holes on the clamping plate 22. The hole fixes the position of the protective net body 3, thus facilitating the installation of the protective net body 3. The connecting rod 4 and the arc-shaped threaded tube 12 are connected by threads. The threaded connection can ensure the connection strength between the connecting rod 4 and the arc-shaped threaded tube 12, and can also facilitate the splicing of the installation frame 1 and the installation frame 1. The outer circumferential distribution of the connecting rod 4 has protrusions, which can increase the friction between the connecting rod 4 and the palm, and facilitate the connection between the connecting rod 4 and the arc-shaped threaded tube 12. The limiting plate 2 and the installation frame 1 are arranged in parallel with each other. The parallel arrangement allows the limiting plate 2 to work with the clamping plate 22 to fix the position of the protective net body 3.

[0036] The working principle of this utility model is as follows: When using the device, the fixing ring 31 is sleeved on the plug rod on the limiting plate 2, and then the clamping plate 22 is installed above the limiting plate 2 through the sliding groove and plug hole. The clamping plate 22 is fixed by the threaded rod 21 in conjunction with the nut and washer. The other side of the protective net body 3 is fixed in the same way as above, thus completing the installation of the device. When disassembling, it is only necessary to unscrew the nut on the threaded rod 21. The above method allows a single person to replace the protective net body 3, ensuring the efficiency and effectiveness of the replacement of the protective net. The connection between the installation frame 1 and the installation frame 2 is made by bolts in conjunction with the installation bracket 11 to connect the installation frame 1. The arc-shaped threaded tube 12 is spliced ​​to form a threaded tube, and the connecting rod 4 is screwed on the arc-shaped threaded tube 12 to complete the splicing of the installation frame 1. After the splicing is completed, the connecting rod 4 is installed on the scaffolding by the clamp to complete the installation of the device. During the use of the device, the fixing ring 31 can effectively increase the strength of the connection point between the protective net body 3 and the plug rod, and prevent the protective net body 3 from separating from the plug rod due to pulling.
