Description

Technical Field

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

[0002] Construction engineering encompasses the planning, surveying, design, construction, and completion of various technical tasks related to the construction, renovation, or expansion of buildings and ancillary structures and facilities, as well as the installation of associated lines, pipelines, and equipment. During the construction of buildings, protective netting needs to be installed on the outside of the scaffolding to protect construction workers from falls and reduce dust leakage during construction.

[0003] The published patent document with announcement number CN220504596U discloses a protective net for construction projects. This published patent document has a simple structure and is easy to use. By adjusting the bolts, the frame can be firmly connected to the steel pipe with the cooperation of the first and second arc plates, thereby ensuring the stability of the frame and the protective net and improving the protective effect of the net. However, scaffolding is generally large in size, and a large number of protective nets need to be installed on the outside of the scaffolding. When multiple protective nets are installed, the above-mentioned patent document does not have a connection and support between the frames. When the connection between a single frame and the scaffolding becomes loose, a single frame is prone to fall, resulting in poor safety. Utility Model Content

[0004] The purpose of this utility model is to provide a protective net for construction projects, which solves the problems mentioned in the background art.

[0005] This application provides a protective net for construction projects, including a protective net frame and several I-shaped connectors. Two T-slots are formed on the outer walls of the protective net frame. The I-shaped connectors are adapted to the T-slots, and semi-circular threaded holes are formed on the upper and lower parts of both sides of the I-shaped connectors. A connecting bolt is installed inside each semi-circular threaded hole. Second semi-circular threaded holes are formed on the inner walls of both sides of the T-slots. The front and rear sides of the T-slots and the second semi-circular threaded holes are open, and both the first and second semi-circular threaded holes are adapted to the connecting bolts.

[0006] By adopting the above technical solution, an I-shaped connector is inserted into the T-slot of two protective net frames, and then the connecting bolts are screwed into the corresponding semi-circular threaded holes one and two, so that the seamless assembly between the two protective net frames can be completed. Moreover, the assembled protective net frames are interconnected. When the connection between one protective net frame and the building scaffold steel pipe becomes loose, the other adjacent protective net frames provide connection support for it.

[0007] Optionally, the protective net frame has grooves on all four sides of its front side, and a slider is slidably connected inside the groove. An arc-shaped component is fixedly connected to the front end of the slider, and an arc-shaped component is provided in front of the arc-shaped component. Connecting ears are symmetrically fixedly connected to both sides of the arc-shaped component. A screw is fixedly connected to the front side of the connecting ear, and a matching nut is fitted on the screw. Connecting ears are symmetrically fixedly connected to both sides of the arc-shaped component. The screw passes through the connecting ear and the connecting ear is closed to the screw.

[0008] By adopting the above technical solution, the slider slides along the groove to align the arc-shaped part one with the steel pipe of the building scaffold. The nut is rotated to lock the arc-shaped part one and the arc-shaped part two onto the steel pipe of the building scaffold. This not only facilitates the installation of the protective net and the scaffold, but also makes it easy to adjust the installation position.

[0009] Optionally, a fixing lug is fixedly connected to one of the arc-shaped parts, and a fixing bolt is threaded through and connected to the fixing lug.

[0010] By adopting the above technical solution, rotating the fixing bolts so that their rear ends contact and abut against the protective net frame, the arc-shaped parts one and two after adjusting the installation position can be fixed.

[0011] Optionally, the inner wall of the first arc-shaped component is fixedly connected with several protruding strips at equal intervals, and the inner wall of the second arc-shaped component is fixedly connected with several protruding strips at equal intervals.

[0012] By adopting the above technical solution, the friction between the first and second curved parts and the steel pipes of the building scaffolding is increased.

[0013] Optionally, a protective net body is fixedly installed inside the protective net frame, and the protective net body includes wire mesh and dustproof net from front to back.

[0014] By adopting the above technical solutions, the wire mesh serves to protect construction workers from falling, while the dustproof net prevents the leakage of construction dust.

[0015] Optionally, the dustproof net is 2000 mesh.

[0016] By adopting the above technical solutions, the dustproof effect is guaranteed.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application can be completed by inserting an I-shaped connector into the T-slot of two protective net frames, and then screwing the connecting bolts into the corresponding semi-circular threaded holes one and two, so that the two protective net frames can be seamlessly assembled. The assembled protective net frames are interconnected. When the connection between one protective net frame and the building scaffold steel pipe is loose, the other adjacent protective net frames provide connection support to prevent the single protective net frame from falling, thus ensuring high safety.

[0019] 2. The technical solution of this application uses a slider to slide along the groove to align the arc-shaped part one with the steel pipe of the building scaffold. Then, the arc-shaped part two is placed in front of the arc-shaped part one, so that the screw passes through the connecting ear two. The nut is rotated to lock the arc-shaped part one and the arc-shaped part two onto the steel pipe of the building scaffold. This not only facilitates the installation of the protective net and the scaffold, but also makes it easy to adjust the installation position. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-2 This utility model provides a protective net for construction projects, including a protective net frame 1 and several I-shaped connectors 2. Two T-slots 5 are opened on the outer walls of the protective net frame 1. The I-shaped connectors 2 are adapted to the T-slots 5. Semi-circular threaded holes 7 are opened on the upper and lower parts of both sides of the I-shaped connectors 2. A connecting bolt 6 is installed inside the semi-circular threaded holes 7. Semi-circular threaded holes 8 are opened on the inner walls of both sides of the T-slots 5. The front and rear sides of the T-slots 5 and the semi-circular threaded holes 8 are open. The semi-circular threaded holes 7 and 8 are adapted to the connecting bolts 6.

[0028] In this technical solution, by inserting an I-shaped connector 2 into the T-slot 5 of the two protective net frames 1, and then screwing the connecting bolt 6 into the corresponding semi-circular threaded hole 7 and semi-circular threaded hole 8, the seamless assembly between the two protective net frames 1 can be completed. Moreover, the assembled protective net frames 1 are interconnected. When the connection between one protective net frame 1 and the building scaffold steel pipe becomes loose, the other adjacent protective net frames 1 provide connecting support to prevent the single protective net frame 1 from falling, thus ensuring high safety.

[0029] In some technical solutions, such as Figure 1 and Figure 3 As shown, the protective net frame 1 has grooves 3 on all four sides of the front side. A slider 9 is slidably connected inside the groove 3. An arc-shaped part 10 is fixedly connected to the front end of the slider 9. An arc-shaped part 2 11 is provided in front of the arc-shaped part 10. Connecting ears 12 are symmetrically fixedly connected to both sides of the arc-shaped part 10. A screw 13 is fixedly connected to the front side of the connecting ears 12. A matching nut 14 is fitted on the screw 13. Connecting ears 2 15 are symmetrically fixedly connected to both sides of the arc-shaped part 2 11. The screw 13 passes through the connecting ears 2 15, and the connecting ears 2 15 and the screw 13 are connected with a clearance fit.

[0030] In use, by sliding the slider 9 along the groove 3, the arc-shaped part 10 is aligned with the steel pipe of the building scaffold. Then, the arc-shaped part 21 is placed in front of the arc-shaped part 10, so that the screw 13 passes through the connecting ear 25. The nut 14 is rotated to lock the arc-shaped part 10 and the arc-shaped part 21 onto the steel pipe of the building scaffold. This not only facilitates the installation of the protective net and the scaffold, but also makes it easy to adjust the installation position.

[0031] In some technical solutions, such as Figure 3 As shown, a fixing ear 16 is fixedly connected to the arc-shaped part 10, and a fixing bolt 17 is threaded through and connected to the fixing ear 16.

[0032] In use, the curved parts 10 and 11 can be fixed by rotating the fixing bolt 17 so that its rear end contacts and abuts against the protective net frame 1 after the installation position is adjusted.

[0033] In some technical solutions, such as Figure 3 As shown, the inner wall of the arc-shaped part 10 is fixedly connected with several protrusions 18 at equal intervals, and the inner wall of the arc-shaped part 11 is fixedly connected with several protrusions 19 at equal intervals.

[0034] In use, multiple protrusions 18 and 19 increase the friction between the arc-shaped parts 10 and 11 and the steel pipes of the building scaffolding.

[0035] In some technical solutions, such as Figure 4 As shown, a protective net body 4 is fixedly installed inside the protective net frame 1. The protective net body 4 includes a wire mesh 41 and a dustproof net 42 from front to back.

[0036] When in use, the wire mesh 41 serves to protect construction workers from falling, while the dustproof net 42 prevents construction dust from leaking out.

[0037] In some technical solutions, such as Figure 4 As shown, the dustproof net 42 has a mesh size of 2000.

[0038] When in use, the 2000-mesh dustproof net 42 ensures the dustproof effect.

[0039] Working principle: During installation, slide the slider 9 along the slide groove 3 to align the arc-shaped part 10 with the steel pipe of the building scaffold. Then place the arc-shaped part 2 11 in front of the arc-shaped part 10, so that the screw 13 passes through the connecting ear 2 15. Rotate the nut 14 to lock the arc-shaped part 10 and the arc-shaped part 2 11 onto the steel pipe of the building scaffold. Insert an I-shaped connector 2 into the T-slot 5 of the two protective net frames 1. Then screw the connecting bolt 6 into the corresponding semi-circular threaded hole 1 7 and semi-circular threaded hole 2 8. This completes the seamless assembly between the two protective net frames 1. The assembled protective net frames 1 are interconnected. When the connection between one protective net frame 1 and the steel pipe of the building scaffold is loose, the other adjacent protective net frames 1 provide connection support to prevent the single protective net frame 1 from falling.
