Technical Field

The utility model relates to a bridge floor construction technical field especially relates to bridge floor prefabricated T roof beam continuous section stretch-draw engineering hangs ladder.

Background

In highway construction, especially in the high-altitude area of southwest China, mountain and mountains fluctuate, the topography is complicated, mountain area highway bridge pier is generally higher, and is in hillside or valley, and after the installation of bridge T roof beam, when the stretch-draw of bridge floor continuous end, because the position of boundary beam continuous section stretch-draw is in the T roof beam back, the inconvenient operation platform of putting up, in the stretch-draw construction, work efficiency is low, can influence the time limit for a project even.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is to solve the shortcoming that exists among the prior art to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: including hanging fixing device, erecting ladder and safe operation platform, hang fixing device and bridge floor embedded steel bar and adopt to link the pull rod spare, pass bridge floor system embedded steel bar to the pull rod spare and fix, hang fixing device end and adopt scalable screw thread device, can hang the flexible regulation of end. The vertical ladder is composed of a part above the bridge deck and a part below the bridge deck, the part, higher than the bridge deck, of the vertical ladder plays a role in protection, an operator can enter the safe operation platform through the vertical ladder, the safe operation platform is composed of a safety fence and a bottom telescopic device, and the levelness of the operation platform can be adjusted by the bottom telescopic device to create a good construction environment. The whole hanging ladder can be folded, the installation process is simple, the assembly and disassembly are very convenient, the working efficiency of construction operation is greatly improved, and the safety of construction operation personnel is ensured.

The utility model discloses a technological effect and advantage: the whole hanging ladder can be folded, the installation process is simple, the assembly and disassembly are very convenient, the working efficiency of construction operation is greatly improved, and the safety of construction operation personnel is ensured.
