Description

Technical Field

[0001] This utility model specifically relates to a fence device for a ramp used in road and bridge construction, belonging to the field of road and bridge construction. Background Technology

[0002] During road and bridge construction, sloping areas present numerous safety hazards, making the installation of fencing crucial. Firstly, construction materials, tools, or soil and rocks on the slope may roll down due to vibration or collision. Fencing can prevent these objects from falling onto the construction site or road below, ensuring the safety of personnel and passing vehicles and maintaining smooth traffic flow. Secondly, road and bridge construction involves large machinery and complex procedures. Fencing clearly demarcates the construction area, isolating it from the outside world, preventing unauthorized personnel from entering, reducing safety accidents, and avoiding disruption to surrounding traffic and residents' lives. In construction sections near slopes, fencing can also buffer and prevent out-of-control vehicles from running off the slope, reducing traffic accidents and ensuring the safety of vehicles and personnel.

[0003] During road and bridge construction, the size of the space between the bottom of the fence and the ground varies depending on the slope, which can cause numerous problems. Firstly, small wild animals may squeeze through this space into the construction site, interfering with construction activities by crawling through, gnawing on materials, or even being injured by construction machinery, thus hindering progress and endangering their own safety. Secondly, some personnel may squeeze through the bottom of the fence to take shortcuts, which not only disrupts construction but also exposes them to risks such as being hit by machinery or falling and getting injured, increasing the difficulty of construction management and potentially causing accidents due to a lack of understanding of the construction environment, endangering their own lives and the lives of others. Furthermore, the existence of the space at the bottom of the fence compromises its protective function, allowing larger objects or rocks to enter the construction site, affecting normal construction and threatening the safety of workers and equipment. Moreover, the space at the bottom of the fence may also provide opportunities for criminals to enter the construction site for theft, vandalism, and other activities, causing unnecessary losses to the project. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a fence device for road and bridge construction slopes is provided to solve the above problems.

[0005] A fencing device for a road and bridge construction slope includes positioning piles and a barrier plate, with the barrier plate mounted on the positioning piles. The barrier plate includes two side bars, an upper crossbeam, a lower crossbeam, several railings, and two connecting lugs. Each side bar has two connecting lugs along its length on one side and a strip groove along its length on the other side. The two side bars are arranged opposite each other. One end of the upper crossbeam is hinged to the upper end of one of the two strip grooves, and the other end of the upper crossbeam is hinged to the upper end of the other strip groove. One end of the lower crossbeam is hinged to the lower end of one of the two strip grooves, and the other end of the lower crossbeam is hinged to the lower end of the other strip groove. The lower end of the upper crossbeam has a hinge groove along its length, and the lower crossbeam has a strip-shaped through hole along its length. Several railings are arranged along the length of the strip groove, with the upper end of each railing hinged in the hinge groove and the lower end of each railing hinged in the strip-shaped through hole.

[0006] Each railing includes a railing body, an extension rod, a threaded rod, and a base. The lower end of the railing body has a telescopic hole machined along its length. One end of the extension rod passes through the telescopic hole, and the other end of the extension rod is fixedly connected to one end of the threaded rod. The other end of the threaded rod is provided with a base, and the threaded rod is threadedly connected to the telescopic hole.

[0007] As a preferred embodiment: the positioning pile includes a positioning pile body, four connecting lugs 2 and four bolts. Two connecting lugs 2 are respectively provided on both sides of the positioning pile body along its length direction.

Detailed Implementation

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0017] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This embodiment describes a fencing device for a road and bridge construction slope, comprising a positioning pile 1 and a barrier plate 2, the barrier plate 2 being mounted on the positioning pile 1. The barrier plate 2 includes two side bars 2-1, an upper crossbeam 2-2, a lower crossbeam 2-3, several railings 2-4, and two connecting lugs 2-5. Each side bar 2-1 has two connecting lugs 2-5 along its length on one side, and a strip groove 2-12 is machined along its length on the other side. The two side bars 2-1 are arranged opposite each other. One end of the upper crossbeam 2-2 is hinged to the upper end of one of the two strip grooves 2-12, and the other end of the upper crossbeam 2-2 is hinged to the upper end of the other strip groove 2-12. One end of the lower crossbeam 2-3 is hinged to the lower end of one of the two strip grooves 2-12, and the other end of the lower crossbeam 2-3 is hinged to both strip grooves 2-12. At the lower end of the other strip groove 2-12 in section 2, the lower end of the upper crossbeam 2-2 is machined with a hinge groove 2-21 along its length, and the lower crossbeam 2-3 is machined with a strip-shaped through hole 2-31 along its length. Several railings 2-4 are arranged within the strip groove 2-12 along its length. The upper end of each railing 2-4 is hinged within the hinge groove 2-21, and the lower end of each railing 2-4 is hinged within the strip-shaped through hole 2-31. Each railing 2-4 includes a railing main... The railing consists of a body 2-41, an extension rod 2-42, a threaded rod 2-43, and a base 2-44. The lower end of the railing body 2-41 has a telescopic hole 2-41-1 machined along its length. One end of the extension rod 2-42 passes through the telescopic hole 2-41-1, and the other end of the extension rod 2-42 is fixedly connected to one end of the threaded rod 2-43. The other end of the threaded rod 2-43 is provided with a base 2-44, and the threaded rod 2-43 is threadedly connected to the telescopic hole 2-41-1.

[0018] The upper crossbeam 2-2 and the lower crossbeam 2-3 of the balustrade 2 are respectively hinged between the two side bars 2-1, and several railings 2-4 are respectively hinged between the upper crossbeam 2-2 and the lower crossbeam 2-3, so the balustrade 2 has the ability to deform as a whole.

[0019] Rotate the base 2-44 to disengage the threaded rod 2-43 from the telescopic hole 2-41-1. At this time, the extension rod 2-42 extends out from the telescopic hole 2-41-1, thereby sealing the space between the road surface and the lower crossbeam 2-3.

[0020] Specific Implementation Method 2: This implementation method is a further limitation of Specific Implementation Method 1. The positioning pile 1 includes a positioning pile body 1-1, four connecting ears 2-2 and four bolts 1-3. Two connecting ears 2-2 are respectively provided on both sides of the positioning pile body 1-1 along its length direction. The two connecting ears 2-2 on one side are corresponding to two connecting ears 1-5. The connecting ears 2-2 and connecting ears 1-5 are connected by bolts 1-3.

[0021] The working principle of this utility model:

[0022] In the sloping area, the pile positions are determined, and multiple positioning piles 1 are fixed at different pile positions. Subsequently, the guardrail 2 is installed between two adjacent positioning piles 1. The upper crossbeam 2-2 and the lower crossbeam 2-3 of the guardrail 2 are each hinged between two side bars 2-1, and several railings 2-4 are each hinged between the upper crossbeam 2-2 and the lower crossbeam 2-3. Therefore, the guardrail 2 has the overall deformation capacity to adapt to the height difference between the various positioning piles 1.

[0023] However, the road surface in the sloping area during construction is uneven, causing a difference in the distance between the road surface and the lower crossbeam 2-3. When this distance is too large, the base 2-44 can be rotated to disengage the threaded rod 2-43 from the telescopic hole 2-41-1. At this time, the extension rod 2-42 extends from the telescopic hole 2-41-1, thereby sealing the space between the road surface and the lower crossbeam 2-3, achieving a complete seal.
