Description

Technical Field

[0001] This utility model relates to the field of dust control and isolation technology in building engineering, specifically a dust control and isolation net for building engineering. Background Technology

[0002] During construction, operations such as earthwork excavation, material handling, cutting, and grinding generate a large amount of dust. These dust particles remain suspended in the air, increasing the concentration of inhalable particulate matter (PM10, PM2.5, etc.). Dust control measures can effectively prevent dust from spreading to the surrounding environment, reduce its impact on air quality, protect the air quality of the surrounding area, and reduce the likelihood of severe weather such as smog. Construction dust contains a large number of tiny particles that can be inhaled into the respiratory tract. Construction workers and nearby residents who are exposed to high concentrations of dust for extended periods have a significantly increased chance of developing respiratory diseases (such as bronchitis, pneumonia, and asthma). Dust control measures can reduce people's exposure to these harmful dust particles and protect their health.

[0003] Chinese Patent 202020420534.0 discloses a dustproof net for construction engineering, belonging to the field of construction engineering technology. The dustproof net includes a first support column and a second support column. The second support column has a first groove and a second groove respectively. A second rotating shaft is rotatably connected within the first groove. A rotating disk is mounted on the second rotating shaft, and a dustproof net body is also wound around the second rotating shaft. Two rotating disks are symmetrically designed, and the dustproof net body is located between the two rotating disks. The end of the dustproof net body away from the second rotating shaft is fixedly connected to the first support column. This utility model has a simple structure and convenient operation. Through the cooperation of the motor and the second rotating shaft, the dustproof net body can be flexibly extended and retracted. The hollow plate allows for flexible adjustment of the height of the extended and retracted dustproof net body. The cooperation of the fixing block and the fixing groove effectively improves the relative position of the dustproof net device.

[0004] Existing dust control nets for construction projects have several drawbacks. Vertical dust control nets are typically installed vertically, making it difficult for dust adhering to the surface to be cleaned on its own. This requires manual cleaning, which is quite cumbersome. Additionally, the area that construction dust control nets need to protect is generally large, resulting in a large footprint and heavy weight for the entire dust control net support frame, making transportation difficult.

[0005] To address the aforementioned issues, a dust control netting for construction projects is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a dustproof isolation net for construction projects, which solves the problems in the background technology that vertically set dustproof nets are difficult to self-clean and that the dustproof net supports occupy a large space.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dustproof isolation net for construction projects, comprising a dustproof isolation net cloth, wherein a net cloth fixing component is installed at the end of the dustproof isolation net cloth, the net cloth fixing component includes a fixing hole, and the fixing hole is opened on the side of a first end receiving block, a support beam splicing component is installed on the other side of the first end receiving block, the support beam splicing component includes a threaded connecting block, and the threaded connecting block has a threaded connection port on its external thread, an anti-detachment block is fixedly connected to the end of the threaded connection port, and a limit cylinder is rotatably connected to the external side of the anti-detachment block.

[0011] Preferably, the outer diameter of the anti-detachment block is larger than the inner diameter of the opening of the limiting cylinder, and the anti-detachment block can slide back and forth inside the limiting cylinder. The threaded connection port forms a rotating structure with the limiting cylinder through the anti-detachment block, and the limiting cylinder is fixedly connected to the first end receiving block.

[0012] Preferably, the fixing hole is engaged with one end of the fixing post, and the fixing post passes through the interior of the fixing ear, and the fixing ear is fixedly connected to the dustproof isolation mesh.

The cross-sectional shape of each support beam is set as "I" shape, which has stronger bending resistance. The cross-sectional shape of the I-shaped pipe can minimize the amount of material used while ensuring structural strength, thereby reducing production costs.

[0025] 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.

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0027] Example 1

[0028] Please see Figure 1 , Figure 2 and Figure 3 This utility model discloses a dustproof isolation net for construction projects, comprising a dustproof isolation net 1, with a net fixing assembly 2 installed at one end of the dustproof isolation net 1. The net fixing assembly 2 includes a fixing hole 204, which is located on the side of a first end receiving block 3. A support beam splicing assembly 4 is installed on the other side of the first end receiving block 3. The support beam splicing assembly 4 includes a threaded connecting block 401, and the threaded connecting block 401 has a threaded connection port on its external thread. 402, the end of the threaded connection port 402 is fixedly connected to an anti-detachment block 403, and the outside of the anti-detachment block 403 is rotatably connected to a limiting cylinder 404. The outer diameter of the anti-detachment block 403 is larger than the inner diameter of the opening end of the limiting cylinder 404, and the anti-detachment block 403 can slide back and forth inside the limiting cylinder 404. The threaded connection port 402 forms a rotating structure with the limiting cylinder 404 through the anti-detachment block 403, and the limiting cylinder 404 is fixedly connected to the first end receiving block 3.

[0029] When not in use or during transport, all support beams of this device are in a disassembled state. When in use, the support beams can be spliced ​​together using the support beam splicing assembly 4 to form the support frame of the entire dustproof isolation net. Before splicing, most of the threaded connection port 402 is slidably retracted into the limiting cylinder 404. During splicing, the threaded connection block 401 is aligned with the port of the threaded connection port 402, and the threaded connection port 402 is rotated. Under the action of the thread, the threaded connection port 402 gradually moves outward and screws onto the outside of the threaded connection block 401, thus completing the fixation. During splicing, only the threaded connection port 402 needs to be rotated, without rotating the entire support beam, to complete the threaded fixation between the two support beams. The structure is simple and the operation is convenient. Furthermore, when not in use or during transport, the entire support frame can be disassembled, which saves floor space and makes transportation more convenient.

[0030] Please see Figure 1 , Figure 4 and Figure 5 This utility model discloses a dustproof isolation net for construction engineering. Threaded connecting blocks 401 are welded to both ends of a supporting horizontal beam 5. A supporting vertical beam 6 is welded to the bottom of a first end receiving block 3, and a second end receiving block 7 is welded to the bottom of the supporting vertical beam 6. A supporting bottom beam 8 is welded to the side of the second end receiving block 7, and a third receiving block 9 is welded to the end of the supporting bottom beam 8. The upper and lower edges of the dustproof isolation net 1 are connected to the first end receiving block 3 and the third receiving block 9 respectively via a net fixing assembly 2 to form a detachable structure. The dustproof isolation net 1 is inclined. The cross-sectional shapes of the supporting horizontal beam 5, supporting vertical beam 6, and supporting bottom beam 8 are all "I"-shaped. The supporting horizontal beam 5 and supporting vertical beam 6 are perpendicular to each other, and the supporting vertical beam 6 and supporting bottom beam 8 are also perpendicular to each other.

[0031] The interaction between the supporting vertical beam 6 and the supporting bottom beam 8 can support the dustproof isolation net 1 into an inclined surface. The inclined structure of the net surface increases the direct contact area between the net surface and rainwater in rainy weather, making it easier for rainwater to wash the net surface and carry away dust and pollutants. This facilitates the self-cleaning of the net surface without much manual operation, and the cleaning is completed by natural rainwater, which saves manpower and resources.

[0032] Furthermore, the cross-sectional shape of each supporting beam is set as "I" shape, which is reasonable. The "I" shape allows it to distribute stress to the upper and lower flanges and web when subjected to bending loads. Compared with other shapes of pipes, such as round or square pipes, it has stronger bending resistance. Moreover, the cross-sectional shape of the I-shaped pipe can minimize the amount of material used while ensuring structural strength, thus reducing production costs. Compared with solid steel with the same load-bearing capacity, the I-shaped pipe is lighter, saving material costs. During construction, the lighter weight of the I-shaped pipe makes it easier to transport and install, reducing the input of manpower and machinery, and lowering construction costs and time.

[0033] Please see Figure 3 This utility model discloses a dustproof isolation net for construction engineering. A fixed insertion hole 204 is engaged with one end of a fixed insertion post 202, and the fixed insertion post 202 passes through the interior of a fixed hanging ear 203. The fixed hanging ear 203 is fixedly connected to the dustproof isolation net 1. A fixed pressure plate 201 is fixedly connected to the other end of the fixed insertion post 202. A through hole 205 is opened at the top of the fixed pressure plate 201, and a fixed bolt 206 passes through the interior of the through hole 205. A bolt end 207 is fixedly connected to one end of the fixed bolt 206, and a fixed screw hole 208 is threaded to the other end of the fixed bolt 206. The fixed screw hole 208 is opened on the outer wall of the first end receiving block 3. The inner diameter of the through hole 205 is larger than the outer diameter of the fixed bolt 206, and the inner diameter of the through hole 205 is smaller than the outer diameter of the bolt end 207.

[0034] Once the entire support frame is assembled, simply pass the fixing post 202 through the fixing lug 203 and insert its end into the fixing hole 204. Then, pass the fixing bolt 206 through the through hole 205 and screw it into the fixing screw hole 208 to complete the fixing between the dustproof isolation net 1 and the support frame. The structure is simple and the operation is convenient.

[0035] Please see Figure 1 This utility model provides a dustproof isolation net for construction projects. The third receiving block 9 has a fixing plate 10 welded to its side, and the fixing plate 10 has an expansion screw 11 connected to its internal thread. By passing the expansion screw 11 through the fixing plate 10 and screwing it into the ground, this device can be fixed next to the construction site for dustproof isolation.
