Description

A mobile hanger used in the construction of building bridge guardrails

technical field

The utility model relates to the field of building and bridge construction, in particular to a mobile hanger used in the construction of building bridge guardrails.

Background technique

During the concrete construction of the guardrail of the bridge project, it is necessary to support the inner and outer formwork first, so that the workers can safely stand on the bridge surface to support the inner formwork, but for the outer formwork, the construction personnel did not have a standing operating platform. Usually, the scaffolding is erected from the ground, and the construction personnel stand on the scaffolding platform to support the external formwork, or use large-scale mechanical equipment such as cranes to cooperate with the construction.

Under normal circumstances, it is more difficult to set up scaffolding platforms or use large-scale mechanical equipment such as cranes for high-altitude operations, resulting in low construction efficiency, high material consumption, and high construction costs. Moreover, it is greatly affected by site restrictions. Once there are rivers, deep ditches, slopes, soft soil layers under the bridge, or frequent traffic under the bridge, or heavy machinery and equipment under the bridge, it will be more difficult to erect scaffolding. Big, not even safe.
