Description

Technical Field

[0001] This utility model relates to the field of road construction fence technology, and in particular to a road construction fence-type dust prevention device. Background Technology

[0002] Road engineering refers to the entire process of planning, designing, constructing, maintaining and managing roads, as well as the physical engineering work involved. During road construction, a large amount of dust is generated. To protect pedestrians from dust pollution, dust control devices are usually installed around the construction site.

[0003] However, existing dust control devices for construction sites typically consist of a metal fence surrounding the construction site. The bottom of the metal fence is not secured, so it is easily blown over by a slight wind. In addition, the metal fence is composed of multiple metal sheets, with large gaps at the joints of each sheet. Dust generated during construction can seep through these gaps, resulting in poor dust control. Furthermore, the metal fence can only prevent dust, but it cannot effectively isolate the noise generated during construction.

[0004] Chinese Patent CN219176055U discloses a dust control device for urban road construction fences. This dust control device is fixed to the ground by a first screw, and the reinforcing plate and the base plate are integrated, thus the reinforcing plate is stable on the ground. The lower end of the baffle is inserted into the reinforcing plate, which greatly enhances the stability of the bottom of the baffle. It is provided with a positioning groove, a positioning block, a side plate, a second threaded hole, and a second screw. The positioning groove and the positioning block facilitate the alignment of the two reinforcing plates and make the assembly of the reinforcing plates easier. By screwing the second screw clockwise into the second threaded hole, the connection of the two side plates is completed, thus completing the splicing of the reinforcing plates. This utility model solves the above problems by proposing another technical solution. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a road construction fence-type dust prevention device, which effectively solves the deficiencies of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a road construction fence-type dust control device, comprising two base plates, with a support column fixedly connected to the top of each of the two base plates, three first mounting seats fixedly connected to both sides of each of the two support columns, and second mounting seats fixedly connected to the bottom ends of each of the two support columns near the sides of the first mounting seats. A support seat is slidably connected between adjacent mounting seats, and multiple card seats are provided on one side of the top surface of each support seat. Three horizontally placed limiting frames are provided between six adjacent first mounting seats, and multiple slots are opened on the top surface of the three limiting frames. Vertically placed baffles are slidably connected inside the multiple slots, and the bottom ends of the multiple baffles are slidably connected to the multiple card seats respectively. A baffle is provided on the top surface of the topmost limiting frame, and a protective component is provided between the baffle and the support seat. The protective component consists of a perforated plate, a sound-absorbing layer, and a protective plate.

[0007] Preferably, the bottom ends of both support columns are fixedly connected to the base plate by welding. Both support columns are hollow square tube structures. This method facilitates direct cutting and processing of profiles, makes it easy to select the size of the support square tubes, and allows them to be purchased directly from the market. The support columns are then fixedly connected to the base plate using a welding machine, which is convenient for users to process and manufacture, and also facilitates subsequent construction and installation.

[0008] Preferably, in any of the above solutions, the side of the support base away from the top surface of the card seat is tilted upwards, and both ends of the support base are in contact with the top surface of the base plate. By using this solution, the bottom end of the support base can smoothly contact the base plate and the road surface, isolating the road construction environment and blocking the transmission of noise. At the same time, the upward tilt of one side of the support base facilitates the limiting of the bottom end of the protective component and provides stable support for the protective component.

[0009] Preferably, the longitudinal section of the middle part of the three limiting frames is L-shaped, and the distance between the three limiting frames is the same. This scheme facilitates the uniform distribution of the three limiting frames. At the same time, the L-shaped structure of the three limiting frames facilitates the reservation of installation positions for the baffle, which can then be combined with the baffle to form a limiting structure, while also providing installation positions for the protective components.

[0010] Preferably, the end faces of the plurality of baffles are I-shaped, and one side of the plurality of baffles is flush with the side of the three limiting frames. This design makes it easy to keep the side of the three baffles flush with the side of the three limiting frames, thereby blocking the protective components. At the same time, the I-shaped structure of the baffles has high structural strength, which improves the overall wind resistance performance.

[0011] Preferably, the two sides of the bottom surface of the baffle are bent downwards, and the two ends of the baffle are fixedly connected to two support columns by self-tapping screws. This method facilitates the installation of the baffle on the top of the protective component and a limiting frame, so that the protective component is placed stably and the road construction site is isolated from the outside world.

[0012] This utility model has the following advantages:

[0013] 1. This road construction fence-type dust control device, by setting a base plate and support columns, allows two support columns to be vertically installed on the road surface. By setting support seats, baffles, three limit frames and multiple stop bars, the above parts are combined to form a limiting structure, which facilitates the installation position of the protective components, making the protective components stable and vertically placed. The above structure is safer, has better wind protection, and provides sound insulation and some dust prevention for road construction. At the same time, the overall structure is simple and easy for users to install and use. In addition, the device is sequentially connected and installed around the road construction site, thereby blocking dust to a certain extent.

[0014] 2. This road construction fence-type dust control device consists of a base plate, support columns, support seats, baffles, three limit frames, and multiple stop bars. Two limit frames are slidably connected to six mounting seats. The support seats are in direct contact with the road surface. The baffles limit the movement of multiple stop bars and protective components. It also features a detachable structure, making it easy for users to install and disassemble, and facilitating transportation and reuse. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] like Figures 1 to 7 As shown, a road construction fence-type dust control device includes two base plates 1. Support columns 2 are fixedly connected to the top of each base plate 1. Three first mounting seats 7 are fixedly connected to both sides of each support column 2. Second mounting seats 6 are fixedly connected to the bottom ends of each support column 2 near the sides of the first mounting seats 7. A support seat 3 is slidably connected between adjacent mounting seats 6. Multiple card slots 5 are provided on one side of the top surface of the support seat 3. Three horizontally placed limiting frames 10 are provided between six adjacent first mounting seats 7. Multiple openings are provided on the top surface of the three limiting frames 10. The card slots 11 have vertically placed baffles 9 slidably connected inside. The bottom ends of the baffles 9 are slidably connected to the card seats 5 respectively. The top surface of the top limit frame 10 is provided with a baffle 8. A protective component is provided between the baffle 8 and the support seat 3. The protective component consists of a perforated plate 4, a sound-absorbing layer 12 and a protective plate 13. The perforated plate 4 faces the road construction site, which facilitates the passage of noise through the perforated plate 4 and into the sound-absorbing layer 12. The protective plate 13 blocks the noise, and the sound-absorbing layer 12 facilitates the energy absorption of noise, thereby achieving the effect of sound insulation.

[0025] The bottom ends of the two support columns 2 are fixedly connected to the base plate 1 by welding. Both support columns 2 are hollow square tube structures. As an optional technical solution of this utility model, it is convenient to directly use profile cutting and processing. The size of the support square tube is convenient to select. At the same time, it can be purchased directly from the market. The support columns 2 are fixedly connected to the base plate 1 using a welding machine, which is convenient for users to process and manufacture, and also convenient for subsequent construction and installation.

[0026] The side of the support base 3 away from the top surface of the card seat 5 is raised upwards, and both ends of the support base 3 are attached to the top surface of the base plate 1. As an optional technical solution of this utility model, this allows the bottom end of the support base 3 to smoothly contact the base plate 1 and the road surface, isolating the road construction environment and blocking the transmission of noise. At the same time, the upward raising of one side of the support base 3 facilitates the limiting of the bottom end of the protective component and provides stable support for the protective component.

[0027] The longitudinal section of the three limiting brackets 10 is L-shaped, and the distance between the three limiting brackets 10 is the same. As an optional technical solution of this utility model, this makes it easy for the three limiting brackets 10 to be evenly distributed. At the same time, the L-shaped structure of the three limiting brackets 10 makes it easy to reserve an installation position for the baffle 9, and then combine it with the baffle 9 to form a limiting structure, while providing an installation position for the protective components.

[0028] The end faces of the multiple baffles 9 are I-shaped, and one side of the multiple baffles 9 is flush with the side of the three limit frames 10. As an optional technical solution of this utility model, this makes it easy to keep the side of the three baffles 9 flush with the side of the three limit frames 10, thereby blocking the protective components. At the same time, the I-shaped structure of the baffles 9 has high structural strength, which is used to improve the overall wind resistance performance.

[0029] The two sides of the bottom surface of the baffle 8 are bent downwards, and the two ends of the baffle 8 are fixedly connected to the two support columns 2 by self-tapping screws. As an optional technical solution of this utility model, this makes it easy to install the baffle 8 on the top of the protective component and the limit frame 10, so that the protective component is placed stably and the road construction site is isolated from the outside world.

[0030] The following steps are required when using this road construction fencing-style dust control device:

[0031] 1) During installation, the two base plates 1 are fixedly connected to the road surface using expansion bolts;

[0032] 2) Install the three limit brackets 10 on the two first mounting seats 7, and install the support seat 3 on the second mounting seat 6;

[0033] 3) Multiple stop bars 9 are sequentially installed on three limit brackets 10;

[0034] 4) Install the protective component on one side of the support base 3, and press down the baffle 8. The two ends of the baffle 8 are fixedly connected to the support column 2 by self-tapping screws.

[0035] In summary, when in use, the user sets up a base plate 1 and support columns 2, allowing the two support columns 2 to be vertically installed on the road surface. The user then sets up a support base 3, baffle 8, three limiting frames 10, and multiple stop bars 9. These components combine to form a limiting structure, facilitating the installation of the protective components and ensuring their stable vertical placement. This structure is safer, provides better wind protection, and offers sound insulation and dust prevention for road construction. The overall structure is simple and easy for users to install and use. Furthermore, the base plate 1, support columns 2, support base 3, baffle 8, three limiting frames 10, and multiple stop bars 9 are all connected. Two limiting frames 10 are slidably connected to six mounting seats 6. The support base 3 directly contacts the road surface. The baffle 8 limits the movement of the multiple stop bars 9 and the protective components. The detachable structure facilitates initial installation and subsequent disassembly, making it convenient for transportation and reuse.
