Existing line protective shed frame, protective shred and mounting method

Abstract

The invention discloses an existing line protective shed frame. The existing line protective shed frame is mounted on an existing steel girder chord and comprises at least two groups of protective shred frame units which are arranged at an interval; each protective shred frame unit comprises an anchoring device, a lower beam and a connecting component; the anchoring device is of a hollow frame structure and is detachably clamped on the existing steel girder chord; the lower beam is positioned below the anchoring device; and the two ends of the connecting component are respectively and detachably connected with the anchoring device and the lower beam. The embodiment of the invention provides the existing line protective shed frame; the protective shed frame is modularized; the at least twogroups of the protective shred frame units are arranged on the existing steel girder chord at an interval so that a supporting surface can be formed for carrying load; the protective shred frame unitscan also be mounted simultaneously, so that the mounting period of the conventional protective shed frame is effectively shortened; the effective utilization rate of a railway blockade point is ensured; and the interference to normal operation of an existing line is reduced.

Description

technical field [0001] The invention relates to the technical field of maintenance and renovation of existing railway steel truss bridges, in particular to an existing line protective scaffold, a protective shed and an installation method. Background technique [0002] In the process of maintenance, reinforcement and transformation of railway steel truss bridges, in order to ensure the safety of the railway below, a protective scaffolding is required to be erected above the railway; the erection of the protective scaffolding is generally carried out within the railway blockade, and considering the particularity of the railway, In order to avoid affecting the operation of existing lines, it is required that the erection of the protective scaffolding and the construction content must be completed within a limited time. Therefore, it is required that the erection of the protective scaffolding meet the requirements of rapid construction as much as possible under the premise of en...
