Abstract

The invention relates to a cast-in-place box beam lateral die sliding construction device. The cast-in-place box beam lateral die sliding construction device is characterized by comprising a movable lateral die, a sliding rail and a lifting jack. The movable lateral die is composed of a lateral die body and a walking pulley which is fixedly arranged at the bottom of the lateral die body, the sliding rail is fixedly arranged on a support, the movable lateral die is movably installed on the sliding rail, and the lifting jack is installed between the upper portion of the support and the bottom of the lateral die. The invention further relates to a cast-in-place box beam lateral die sliding construction method. By the adoption of the cast-in-place box beam lateral die sliding construction device and method, the phenomenon that in the construction process of a traditional cast-in-place beam, a large number of hoisting devices and transport vehicles are needed for demounting, reshipping and hoisting the lateral die is effectively avoided, and the cast-in-place box beam lateral die sliding construction device and method are economical, practical, simple in operation, and capable of effectively saving expenditures, shortening labor hours, and possessing obvious economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, in particular to a sliding construction device and method for a side form of a cast-in-place box girder. Background technique [0002] With the development of the national economy, the scale of urban overpasses, expressway viaducts, and high-speed railway viaducts has become larger and larger, and a large number of cast-in-place box girder constructions have occurred. The traditional construction method is: set up the support → install the side formwork → pave the bottom formwork → bind the bottom and web steel bars → install the inner formwork → bind the top plate steel bars and install the embedded parts → pour concrete → concrete curing → remove the formwork. In general, after pouring a box girder with one hole, the side forms need to be removed and transported back to the next hole box girder with a crane and a pallet truck, and then the side forms are installed with a crane. It ...
