Box girder template for municipal road and bridge building construction

Abstract

The invention belongs to the technical field of box girder formworks, particularly relates to a box girder formwork for municipal road and bridge building construction, and aims to solve the problems that a steel frame supporting structure of an existing box girder formwork is insufficient in supporting stability of the box girder formwork, a steel frame needs to be fastened through fasteners during mounting, and time is wasted during mounting due to the fact that the steel frame is large. In order to solve the problems that an existing box girder is inconvenient to disassemble and inconvenient to use in a turnover mode, the following scheme is provided: the box girder comprises a supporting base and a box girder bottom plate, sliding grooves are formed in the two sides of the top of the supporting base, sliding plates are slidably mounted in the two sliding grooves, abutting plates are fixedly mounted at the tops of the two sliding plates, and the two abutting plates movably abut against the two sides of the box girder bottom plate correspondingly. The supporting structure of the box girder formwork is convenient to mount and dismount, so that the mounting efficiency is improved, the supporting structure is convenient to use in a circulating mode, and the overall stability of the box girder formwork is improved by pressing and positioning the box girder formwork.

Description

technical field [0001] The invention relates to the technical field of box girder formwork, in particular to a box girder formwork for municipal road and bridge construction. Background technique [0002] A large amount of formwork is required in the bridge construction process. Due to frequent use, steel structure formwork is often used in bridge construction. Most of the lifting equipment adopts the box girder structure, so people gradually use the box girder formwork to refer to the series of bridge erecting machines. When the box girder formwork is used, the steel frame is generally used to support the formwork, and the steel frame needs to be built, which is cumbersome. Rods are used for support, and it is easy to occupy more floor space. [0003] The steel frame support structure of the existing box girder formwork is not stable enough for the support of the box girder formwork, and the steel frame needs to be fastened by fasteners during installation. Since the stee...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the steel frame support structure of the existing box girder formwork is not stable enough for the support of the box girder formwork, and the steel frame needs to be fastened by fasteners during installation. It is also time-consuming to install, and it is not easy to disassemble, which leads to the shortcomings of being inconvenient for turnover. A box girder formwork for municipal road and bridge construction is proposed.
