Combined sunshade rainproof canopy of prefabricated box girder

Abstract

The invention discloses a combined sunshade rainproof canopy of a prefabricated box girder. The combined sunshade rainproof canopy solves the problems that as existing sunshade rainproof canopies used during prefabricating of box girders and T-shaped beams are dismounted and mounted repeatedly, materials are wasted and construction periods are delayed. According to the combined sunshade rainproof canopy, longitudinal usually-fixed angle steel is welded to a left footway and a right footway, sunshade rainproof canopy support columns are movably arranged between the longitudinal usually-fixed angle steel and box girder flange baffles at equal intervals, triangular supporting frames are arranged at the top ends of the sunshade rainproof canopy support columns, and inserting tubes are fixedly arranged at the tops of the triangular supporting frames; the right end of a left movable frame rod (11) is hinged to the left end of a right movable frame rod (17) through a hinge shaft (16), the left end of the left movable frame rod (11) is inserted in the left inserting tube (8), the right end of the right movable frame rod (17) is inserted in the right inserting tube (20), and rainproof cloth (27) is movably arranged at the right end of the left movable frame rod (11) and the right movable frame rod (17). As a canopy support which is combined in an inserted mode is adopted in the combined sunshade rainproof canopy, the combined sunshade rainproof canopy is convenient to assemble and easy to disassemble.

Description

technical field [0001] The invention relates to a sunshade and rainproof shed, in particular to a sunshade and rainproof shed used in the construction of prefabricated box girder concrete pouring and steel bar binding Background technique [0002] In factory prefabricated girders, the prefabrication of box girders is completed in the open air, and the prefabrication period of monolithic girders is about 3-4 days. The prefabricated box girder’s pre-reinforcement binding process and concrete pouring process cannot be carried out in the rain, so as to ensure that the concrete is not damaged by rainwater. The existing technology is to build a temporary rain-proof sunshade above the prefabricated box girder to meet the process requirements. When the pouring process is completed, it is necessary to dismantle the temporary rain-proof awning to facilitate the gantry crane to carry out the processes of internal and external mold installation, demoulding, and beam removal. Its struct...
