Description

Technical Field

[0001] The utility model relates to the field of road and bridge construction, in particular to a protective isolation net used for road and bridge construction. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of transportation infrastructure, the construction and maintenance of roads and bridges are increasing, and the safety issues at construction sites are becoming increasingly prominent. The isolation and protection net for road and bridge construction is a protective facility designed specifically for road and bridge construction sites. Its main function is to isolate the construction area from the traffic area, ensure the safety of the construction site, and prevent the accidental scattering of materials or tools during construction from causing harm to passing vehicles and pedestrians.

[0003] However, most traditional construction protective isolation nets cannot adjust their height and cannot meet the height requirements of various construction sites. They are also prone to safety problems caused by insufficient height of the isolation nets, which poses hidden dangers to construction sites and pedestrian safety. In addition, when the laying area of ​​the traditional construction protective isolation nets needs to be extended, workers need to use multiple sets of fasteners and bolts to install and fix the two isolation nets, which increases the complexity of the installation to a certain extent and reduces the efficiency of the isolation net installation.

[0004] Therefore, those skilled in the art provide a protective isolation net for road and bridge construction to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings existing in the prior art, and a protective isolation net for road and bridge construction is proposed. When multiple guardrail baffles need to be installed, the worker twists the knob with a wrench to drive the two-way threaded rod to rotate. Through the opposite movement of the movable slider on the threaded rod, the slider and the connecting rod are snapped together to connect multiple sections of protective baffles, thereby extending the protection range, greatly simplifying the process of installing multiple guardrail baffles and the fixed connection between multiple sections of guardrails, significantly reducing the difficulty of installation and improving installation efficiency.

[0006] The top end face of said sliding panel also is provided with an interlocking structure, and the interlocking structure is pivotally connected to the upper end of said sliding panel and the interlocking structure is pivotally connected to the lower end of said sliding panel.

[0007] Through the above technical solution, the connecting column slides inside the column to drive the upper baffle to slide inside the lower baffle, and the upper baffle is limited by the bolts and nuts, so as to facilitate the adjustment of the overall height of the baffle and meet the needs of various construction sites to prevent safety problems caused by insufficient baffle height, providing a safer working environment for construction personnel. Due to the rapid installation and adjustment of the protective isolation net, the construction progress will not be delayed due to waiting for protective measures to be in place, thereby improving the overall construction efficiency.

[0008] Furthermore, the mounting holes on both sides of the outer wall of the front end of the upper baffle are provided with bolts, and the rear ends of the bolts pass through the lower baffle and the upper baffle to the outside of the lower baffle and are threadedly connected with nuts;

[0009] Through the above technical solution, the upper baffle is limited by bolts and nuts, thereby facilitating the adjustment of the overall height of the baffle.

[0010] Furthermore, a warning light is fixedly connected to the upper surface of each connecting column;

[0011] Through the above technical solution, the warning light emits bright light at night or in low visibility environments, which can significantly improve the visibility of the isolation protection net and enable passing vehicles and pedestrians to detect the existence of the construction area from a distance.

[0012] Furthermore, the upper end and the lower end of the bidirectional threaded rod are rotatably connected to the top surface and the bottom surface of the accommodating cavity;

[0013] Through the above technical solution, the two ends of the bidirectional threaded rod are rotatably connected to the top surface and the bottom surface of the accommodating cavity respectively, forming a stable support structure, so that the threaded rod can remain stable during rotation.

[0014] Furthermore, the slider slides inside the accommodating cavity;

[0015] Through the above technical solution, the helical structure of the thread is utilized to convert the rotational motion into linear motion, thereby driving the slider to move.

[0016] Furthermore, a connecting hole is provided on one side of the upper surface of the slider, and the connecting rod is connected to the slider by clamping;

[0017] Through the above technical solution, this design not only provides stability for the connection of multi-section protective nets during expansion, but also facilitates rapid assembly and disassembly.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model proposes a protective isolation net for road and bridge construction.

Due to the rapid installation and adjustment of the protective isolation net, the construction progress will not be delayed due to waiting for protective measures to be in place, thereby improving the overall construction efficiency.
