Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically a protective device for road construction crossing existing subway stations. Background Technology

[0002] For subway stations built in busy urban areas, road construction above the station should be fully enclosed, and if necessary, the area above should also be shielded. On the one hand, full shielding ensures construction safety; on the other hand, since road construction generates a significant amount of dust, full shielding at dust-generating locations can significantly reduce environmental pollution.

[0003] Urban areas experience high pedestrian traffic, and construction site fences are typically tall with large windward areas. Therefore, a comprehensive reduction in wind resistance is necessary. Existing technologies for reducing wind resistance in tall construction site fences tend to focus on localized areas, failing to achieve the desired effect in mitigating wind impact. Utility Model Content

[0004] The purpose of this utility model is to provide a construction protection device for roads crossing existing subway stations, which can effectively reduce the windward area while ensuring the function of the enclosure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective device for construction work through existing subway stations, comprising a protective upright plate and a rectangular plate embedded in the center of the protective upright plate, wherein the interior of the protective upright plate is provided with a matrix of ventilation holes and the interior of the bottom of the protective upright plate is provided with an air guide groove.

[0006] An arc-shaped plate is fixedly installed at the front end of the bottom of the protective upright plate, and two support plates are fixedly installed at the rear end of the bottom of the protective upright plate.

[0007] The rectangular plate has a rectangular groove on its front side, and two symmetrical assembly slots are opened inside the rectangular groove. An identification plate is embedded inside the rectangular groove, and an assembly block that matches the assembly slot is provided on the back side of the identification plate.

[0008] Furthermore, a fluorescent strip is fixedly installed on one side of the protective upright plate where a rectangular groove is formed.

[0009] Furthermore, each of the support plates has a placement groove fixedly installed on its top.

[0010] Furthermore, connecting ropes are fixedly installed on both sides of the protective upright plate, and mounting blocks are fixedly installed on the outer ends of the connecting ropes. Assembly magnets are fixedly installed inside the mounting blocks.

[0011] Furthermore, upright plates are fixedly installed on both sides of the top of the protective upright plate, and a rotating rod is rotatably installed between the two upright plates. A shielding cloth is fixedly connected to the outside of the rotating rod. The shielding cloth is wrapped around the outside of the rotating rod, and an adsorption magnet is fixedly installed at the end of the shielding cloth away from the rotating rod. A hand handle is fixedly installed at one end of the rotating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing heavy objects such as stones inside the placement groove, the stability of the protective upright plate is ensured. In addition, the ventilation holes, arc-shaped plates and air guide channels can facilitate the guidance and ventilation of the wind, which can cleverly prevent strong winds from directly and violently impacting the protective upright plate, greatly reducing the potential threat of wind pressure to the protective structure, further consolidating the overall protective effect, and also helping to improve the comfort of the construction environment, reduce construction obstacles caused by adverse weather conditions, and ensure the progress and quality of the project.

[0013] Multiple protective panels can be assembled using connecting ropes, mounting blocks, and assembly magnets. The appropriate number of protective panels can be selected according to the construction area to expand the protection area. The installed shielding cloth can cover the top of the construction area, ensuring normal construction in rainy or snowy weather and reducing the dispersion of construction dust, thereby improving construction effect and efficiency.

[0019] 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.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a protective device for construction across existing subway station roads, including a protective upright plate 1 and a rectangular plate 2. The protective upright plate 1 has ventilation holes 3 inside, and a wind guide groove 5 inside the bottom of the protective upright plate 1. An arc-shaped plate 6 is fixedly installed on one side of the bottom of the protective upright plate 1. Two support plates 17 are fixedly installed on the side of the protective upright plate 1 away from the arc-shaped plate 6. A rectangular groove 20 is opened on one side of the protective upright plate 1. Two assembly slots 19 are symmetrically opened inside the rectangular groove 20. A sign plate 4 is detachably installed on the front side of the rectangular plate 2. The sign plate 4 has assembly blocks. The outer contour of the assembly blocks 16 matches the inner contour of the assembly slots 19. The two assembly blocks 16 correspond to the positions of the two assembly slots 19 respectively. A fluorescent strip 15 is fixedly installed on the side of the protective upright plate 1 with the rectangular groove 20. Placement slots 18 are fixedly installed on the top of each support plate 17.

[0021] The working principle of the above technical solution is as follows: The protective upright plate 1 can be placed in the construction area to shield it. The curved plate 6 and support plate 17 increase the contact area between the protective upright plate 1 and the ground, ensuring its stability. Additionally, heavy objects such as stones can be placed inside the placement groove 18 to ensure the stability of the protective upright plate 1. The ventilation holes 3, curved plate 6, and air guide duct 5 effectively ventilate, preventing strong winds from directly and violently impacting the protective upright plate 1, significantly reducing the potential threat of wind pressure to the protective structure and further consolidating the overall protective effect. Simultaneously, the ventilation structure helps to form an air inlet, delivering air into the construction site and improving comfort. The assembly blocks 16 and assembly slots 19 work together to form a detachable structure for the signboard 4. Different signboards 4 can be replaced, and different warning signs can be affixed to the signboard 4 to remind passersby to be wary of various dangerous behaviors.

[0022] In another implementation scheme, such as Figures 1-4 As shown, connecting ropes 13 are fixedly installed on both sides of the protective upright plate 1. An installation block 7 is fixedly installed at the end of the connecting rope 13 away from the protective upright plate 1. An assembly magnet 14 is fixedly installed inside the installation block 7.

[0023] Multiple protective uprights 1 can be assembled using the connecting rope 13, mounting block 7, and assembly magnet 14. An appropriate number of protective uprights 1 can be selected based on the construction area to expand the protected area. The connection via the connecting rope 13 is a flexible connection, which can prevent continuous tipping accidents.

[0024] In another implementation scheme, such as Figures 1-4 As shown, upright plates 8 are fixedly installed on both sides of the top of the protective upright plate 1. A rotating rod 11 is rotatably installed inside the upright plate 8. A shielding cloth 9 is fixedly connected to the outside of the rotating rod 11. The shielding cloth 9 is wrapped around the outside of the rotating rod 11, and an adsorption magnet 10 is fixedly installed at the end of the shielding cloth 9 away from the rotating rod 11. A hand handle 12 is fixedly installed at one end of the rotating rod 11.

[0025] The shielding cloth 9 can cover the top of the construction area, which can ensure normal construction in rainy or snowy weather, and reduce the spread of construction dust, thereby improving the construction effect and efficiency.

[0026] Working Principle: The protective panel 1 is placed in the construction area to shield it. The curved plate 6 and support plate 17 increase the contact area between the protective panel 1 and the ground, ensuring its stability. Heavy objects such as stones can be placed inside the placement groove 18 to further stabilize the panel 1. The ventilation holes 3, curved plate 6, and air guide duct 5 facilitate wind guidance and ventilation, preventing strong winds from directly impacting the protective panel 1 and further enhancing the overall protective effect. Assembly blocks 16 and assembly slots 19 facilitate the replacement of the marker plate 4. Multiple protective panels 1 can be assembled using the connecting rope 13, mounting block 7, and assembly magnet 14. The appropriate number of panels can be selected based on the construction area to expand the protective area. The shielding cloth 9 shields the top of the construction area, ensuring normal construction in rainy or snowy weather and reducing dust dispersion. It should be noted that in low wind conditions, the shielding cloth 9 can be attached downwards to the curved plate 6. When there is a lot of dust, it can be extended horizontally to connect to other reliable locations on the site, such as metal roofs in the construction site.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
