Embodiment Construction

[0039] A corrugated rigid web hanging type construction hanging basket, such as figure 1 with 2 As shown, it is mainly composed of a load-bearing system, a hanging lifting system, a walking system, and a formwork system. The load-bearing system includes an upper beam 1, a lower longitudinal beam 8, and a corrugated rigid web 3; Middle fulcrum suspension rod 6, front fulcrum suspension rod 2. The walking system includes a hydraulic rod 12, a groove 13 arranged on the top of the corrugated rigid web 3, a PTFE slide plate 14, a sliding beam 4 and a walking trolley 15; the formwork system includes a top formwork, a bottom formwork, a sealing formwork and a working platform.

[0040] The support beam is embedded in the groove 13 of the corrugated rigid web, the threaded steel bar traverses the through hole and the support beam hole, and the bolts are anchored. The supporting beam 16 is fixed in the groove 13 . Thus, the supporting point of the hanging basket is anchored in the c...

Abstract

The invention discloses a hanging basket for corrugated steel web plate construction and a construction process. The hanging basket for construction comprises an upper beam assembly, a lower beam assembly and multiple groups of hanging rods for connecting the upper beam assembly and the lower beam assembly. A base plate bottom formwork and base plate side formworks are arranged above the lower beam assembly, the upper beam assembly is supported on the top end faces of two corrugated steel web plates through two groups of supporting beams, and thrusting devices are arranged between the supporting beams and the top ends of the corrugated steel web plates. The bottom ends of the corrugated steel web plates are arranged in a base plate concrete casting area. Top plate bottom formworks arranged above the upper beam assembly. Horizontally-arranged sliding beams are arranged on two sides of the corrugated steel web plates, and conveying devices for conveying the base plate bottom formwork, the base plate side formworks and the top plate bottom formworks to the positions to be cast are installed on the sliding beams. The self weight of the hanging basket for corrugated steel web plate construction can be effectively reduced, the security coefficient of the hanging basket can be improved, and the construction efficiency can be accelerated.

Description

technical field [0001] The invention relates to a construction hanging basket with a corrugated rigid web and a construction process, in particular to a hanging basket structure and a construction process for the construction of a corrugated rigid web of a PC beam, and belongs to the technical field of composite beams. Background technique [0002] With the increasing web cracking problems of continuous box girder bridges, corrugated rigid web bridges have been gradually popularized and applied. It has the advantages of light structure, less web cracking and disease, and high economic performance. However, compared with the construction technology of ordinary hanging baskets, its construction technology is separated from the simultaneous pouring of the bottom plate, web and top plate into three working conditions of installing the web, pouring the bottom plate and pouring the top plate. If the construction is carried out according to the conventional hanging basket technolo...
