Abstract

The invention discloses a retractable cast concrete box girder inner mold easy to disassemble and assemble. The retractable cast concrete box girder inner mold easy to disassemble and assemble comprises an upper mold and a lower mold. The upper mold comprises a first upper mold and a second upper mold, and is provided with a first upper mold top surface and a first upper mold side surface. The second upper mold is provided with a second upper mold top surface and a second upper mold side surface. The lower mold comprises a first lower mold and a second lower mold. The first lower mold is provided with a first lower mold bottom surface and a first lower mold side surface, and the upper end of the first lower mold side surface is rotationally connected with the lower end of the first upper mold side surface. The second lower mold is provided with a second lower mold bottom surface and a second lower mold side surface, and the upper end of the second lower mold side surface is rotationally connected with the lower end of the second upper mold side surface. Jacking mechanisms and bendable supporting rods are arranged between the upper mold and the lower mold. After the supporting rods are bent, retraction demolding of the upper mold and the lower mold is achieved through traction ropes. The technical purpose of the retractable cast concrete box girder inner mold easy to disassemble and assemble is to solve the technical problem that the inner mold is difficult to disassemble and assemble in the pouring process of a concrete box girder.

Description

technical field [0001] The invention relates to the technical field of building bridge construction, in particular to an easy-to-disassemble shrinkable pouring concrete box girder inner mold. Background technique [0002] Box girder is a kind of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, which is similar to a box structure, hence the name. The box girder of reinforced concrete structure is divided into prefabricated box girder and cast-in-place box girder. The prefabricated box girder is a box girder prefabricated on an independent site combined with a bridge erecting machine, which can be erected after the completion of the lower part of the project, which can speed up the progress of the project and save the construction period; Cast box girders are mostly used for large continuous bridges. [0003] At present, when prefabricating box girders in China, most of the internal molds are connected by block formwork through ...
