Description

Technical Field

[0001] This utility model relates to the field of construction protection equipment technology, specifically to a kind of isolation fence for road and bridge construction. Background Technology

[0002] Traditional road and bridge construction safety barriers typically consist of posts, mesh panels, and connectors. The mesh panels and posts are usually fixed using bolts or welding. However, this type of installation has significant drawbacks: firstly, bolted connections require individual tightening on-site, and welding relies on specialized equipment and personnel, making the assembly process cumbersome and time-consuming, and difficult to adapt to the frequent adjustments needed during the construction period; secondly, long-term exposure to humid and dusty outdoor environments makes bolts prone to corrosion and welds prone to cracking, leading to mesh loosening, affecting the stability of the barrier, and increasing maintenance costs.

[0003] Meanwhile, traditional safety barriers have a relatively limited functionality, primarily providing only basic isolation. In actual construction, they often face the following problems: First, in the event of a sudden emergency in the construction area (such as a fire or collapse), the barriers lack convenient escape routes, requiring construction workers to break through the mesh to evacuate, delaying escape opportunities; second, some barriers have simple structures, with the mesh installed vertically and at limited height, making it difficult to effectively prevent unauthorized personnel from climbing over them, posing a safety hazard; third, when subjected to external forces such as vehicle impacts or collisions with construction machinery, the overall impact resistance of the mesh is insufficient, easily deforming and breaking, thus losing its isolation and protective function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a road and bridge construction isolation fence that solves the technical problems of traditional isolation fences in terms of ease of installation, emergency response capability, and protective reliability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a road and bridge construction isolation fence, comprising: The column is provided with at least two sets of columns, and two symmetrically arranged slots are opened on the outer wall of the column. A limiting member protruding from the slot is slidably provided on the inner side of the top of the column. A vertical mesh panel is inserted into a slot between two sets of uprights. The top of the vertical mesh panel is fixed in the slot by a limiting member. A door frame is fixed in the middle of the vertical mesh panel, and an emergency door is movably connected to the door frame. The door frame is also equipped with a door lock.

[0006] Preferably, the bottom of the column is fixedly provided with a base, and the base has a waist hole, into which a ground bolt is inserted.

[0007] Preferably, the limiting component includes two limiting blocks movably connected to the inner side of the top of the column, a spring fixed between the two limiting blocks, and a slider fixed on the side wall of the limiting block, the slider being slidably disposed in a groove opened on the inner side of the top of the column.

[0008] Preferably, the end face of the limiting block facing the slide groove is an inclined surface.

[0009] Preferably, two insert plates are bolted to the top of the vertical mesh, and an outward-facing inclined mesh is fixed between the two insert plates.

[0010] Preferably, the top of the column is threaded with a protective cap.

[0011] Preferably, a V-shaped reinforcing plate is fixed to one side of the vertical mesh.

[0012] By employing the above technical solution, this utility model provides a protective fence for road and bridge construction, which has at least the following beneficial effects: This road and bridge construction isolation fence uses slots and limiting components on the posts to fix the vertical mesh panels by inserting and limiting them. After insertion, the vertical mesh panels can be automatically fixed, which has the advantages of simple assembly and rapid construction.

[0013] The construction site safety fence has emergency doors installed on the vertical mesh panels, which can be opened directly to leave the construction site in case of an emergency, thus providing an emergency escape function.

[0014] The construction fence used for this road and bridge project increases the difficulty of climbing by setting inclined mesh panels on vertical mesh panels, which can effectively prevent unauthorized personnel from climbing over and entering the construction area, and has a good isolation effect. This road and bridge construction safety fence significantly enhances the overall structural strength of the vertical mesh by installing reinforcing plates on the vertical mesh panels. This improves the fence's impact resistance, allowing it to better withstand collisions with vehicles and construction machinery, reducing the probability of deformation or breakage of the vertical mesh panels, and ensuring the long-term stability of its protective function.

[0017] 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.

[0018] During the construction of road and bridge projects, in order to ensure the safety isolation of the construction area from the outside world, prevent unauthorized personnel and vehicles from accidentally entering the construction site and causing safety accidents, and at the same time avoid the impact of falling gravel, tools and other debris generated during construction on the surrounding environment, isolation fences are widely used as an important protective facility.

[0019] Due to the technical shortcomings of existing technologies, such as cumbersome installation, lack of emergency escape functions, and poor impact resistance, please refer to... Figures 1-4 This embodiment provides a road and bridge construction isolation fence that uses a plug-in and limiting method to fix the vertical mesh 2. After insertion, the vertical mesh 2 is automatically fixed, offering advantages such as easy assembly and rapid construction. Furthermore, in emergencies, the emergency door 7 can be directly opened to leave the construction site, providing an emergency escape function. It also boasts good isolation effect and impact resistance. The isolation fence includes: posts 1, with at least two sets of posts 1. Two symmetrically arranged slots are provided on the outer wall of each post 1, and a limiting member 5 protruding from the slot is slidably provided on the inner side of the top of each post 1; and vertical mesh 2, which is plugged between the two sets of posts 1. Within the slot, the top of the vertical mesh panel 2 is fixed in place by the limiting member 5. A door frame 6 is fixed in the middle of the vertical mesh panel 2, and an emergency door 7 is movably connected to the door frame 6. The door frame 6 is also equipped with a door lock 8. The slot and limiting member 5 are used for insertion and fixing, eliminating the need for bolts or welding. The vertical mesh panel 2 is automatically fixed after insertion, greatly simplifying the assembly process, enabling rapid construction, and reducing reliance on professional tools and personnel. Furthermore, the emergency door 7 with door lock 8 integrated on the vertical mesh panel 2 can be opened directly in case of emergency, providing a convenient escape route for construction personnel, avoiding the delay in escape due to breaking the mesh panel, and improving emergency safety.

[0020] The traditional method of fixing the base 3 of the isolation fence is complicated and difficult to adapt to the temporary relocation needs of the construction area. Moreover, it is difficult to adjust after fixing. To address this issue, the bottom of the column 1 is fixed with a base 3. The base 3 has a waist hole, and a ground bolt 4 is inserted into the waist hole. The base 3 is fixed by the waist hole and the ground bolt 4, which can not only ensure the overall stability of the isolation fence, but also make the position of the column 1 fine-tuned through the strip design of the waist hole. At the same time, the ground bolt 4 is easy to disassemble, which facilitates the overall relocation or reuse of the isolation fence and improves the flexibility of use.

[0021] Traditional plug-in structures rely heavily on manual operation for their limiting function, resulting in low fixing efficiency and a tendency to fail due to jamming after prolonged use. To address this issue, the limiting component 5 includes two limiting blocks 51 movably connected to the inner side of the top of the column 1. A spring 52 is fixed between the two limiting blocks 51, and a slider 53 is fixed to the side wall of each limiting block 51. The slider 53 is slidably positioned within a groove opened on the inner side of the top of the column 1. The limiting component 5 connects the two limiting blocks 51 via the spring 52. With the slider 53 and the sliding guide of the groove, the vertical mesh 2 is automatically avoided during insertion and automatically reset after insertion, eliminating the need for manual operation and further simplifying the installation process. The elasticity of the spring 52 ensures that the limiting blocks 51 can firmly lock the vertical mesh 2, reducing the risk of loosening and improving fixing reliability.

[0022] Furthermore, the end face of the limiting block 51 facing the slide groove is an inclined surface; with the end face of the limiting block 51 set as an inclined surface, when the vertical mesh 2 is inserted, the limiting block 51 can be automatically retracted by the guiding effect of the inclined surface, so that it can be inserted smoothly without precise alignment, reducing the difficulty of installation and further improving the assembly speed.

[0023] Traditional security fences are mostly single vertical mesh panels 2, which have limited height and lack anti-climbing structures, making them easy for unauthorized personnel to climb over, posing a safety hazard. To address this issue, two insert plates 10 are bolted to the top of the vertical mesh panel 2, with an outward-facing inclined mesh panel fixed between the two insert plates 10. The inclined mesh panel is connected to the top of the vertical mesh panel 2 via the insert plates 10, and the inclined structure physically increases the difficulty of climbing, effectively preventing unauthorized personnel from climbing over into the construction area and strengthening the isolation and protection effect. The insert plates 10 are bolted on, facilitating the disassembly and replacement of the inclined mesh panel, adapting to the anti-climbing requirements of different scenarios.

[0024] Traditional fence posts 1 are mostly open at the top, which easily accumulates rainwater, dust or debris, causing the internal limiting components 5 to rust and jam, affecting their service life. To address this issue, the top of the post 1 is threaded with a cover 12; the threaded cover 12 can seal the top of the post 1, preventing rainwater and dust from entering, protecting the internal limiting components 5 from corrosion, extending the service life of the components, and reducing maintenance costs.

[0025] Traditional vertical mesh 2 has a thin structure and is prone to deformation and breakage when hit by vehicles or machinery, resulting in insufficient impact resistance. To address this issue, a "V"-shaped reinforcing plate 9 is fixed to one side of the vertical mesh 2. The reinforcing plate 9 enhances the overall rigidity of the vertical mesh 2 through a triangular stabilizing structure, disperses external impact, and improves the vertical mesh 2's resistance to deformation and breakage, ensuring that the fence can still maintain its protective function when subjected to collisions, thereby reducing the risk of safety accidents.
