Highway bridge construction fence

Abstract

The invention discloses a highway bridge construction fence. The highway bridge construction fence comprises a construction fence body, and a socket device is arranged on the right side face of the construction fence body; the weight of a bearing device is increased through cooperation of a releasing device and a reinforcing device, the gravity center of the construction fence shifts downwards, and the stability is increased; the length of a force arm between the bearing device and the ground is increased through the reinforcing device, then the external force resistance of construction fence is improved, and the stability is better; through the cooperation of the socket device, a lower locking device, an upper locking device and a control device, the construction fence which are directly stressed can be automatically separated from the adjacent construction fences, it is ensured that the adjacent construction fences cannot be brought down by the construction fences which are directly stressed, and the subsequent maintenance work is simplified; and the external force borne by the construction fence is buffered and absorbed through the bearing device, the deformation difficulty of the construction fence under the external force is increased, and the service life of the construction fence is prolonged.

Description

technical field [0001] The invention relates to the field of road and bridge construction protection equipment, and more specifically relates to a fence used for road and bridge construction. Background technique [0002] Construction fence, also known as construction guardrail, is a finished iron pipe product, which is processed by layers of seamless iron pipe bending, welding, grinding and polishing, high-pressure baking paint, film sticking, etc. It is generally used on ordinary roads, expressways and There are highway crossroads at all levels, toll booths, bridges, parking lots, stations, docks, dangerous areas and road construction sites, temporary fences at assembly places and other places as road lanes, area enclosure safety isolation, diversion, guidance or used in It can also be used for the protection and protection of equipment and facilities in factories, workshops, warehouses, parking lots, commercial areas, public places, etc. To the role of isolation and warn...

AI Technical Summary

Problems solved by technology

[0003] Existing fences used for highway and bridge construction are mainly composed of construction fences, load-bearing bases, L-shaped curved rods, plug-in pipes, etc., wherein the load-bearing bases are directly placed on the ground around the construction site, and the construction fences are fixedly installed on the load-bearing bases. The curved rod is installed on one side of the construction fence, and the plug-in pipe is fixedly installed on the other side of the construction fence. During installation, the two adjacent construction fences are flexibly connected together through the plug-in effect of the L-shaped curved rod and the plug-in pipe. However, the construction fence of this structure is less stable, and it is easy to fall under the action of external force, and the tipping of one construction fence will cause the adjacent construction fence to fall together, which will cause the construction fence to fall easily under the action of external force. A large amount of dumping caused the follow-up maintenance work to be more troublesome. At the same time, no energy-absorbing structure was installed, and the construction fence directly subjected to force was easily deformed under the action of external force. The service life is short, so it is urgent to design a fence for road and bridge construction
