Abstract

The invention provides a formwork for a prefabricated box girder. The formwork for the prefabricated box girder comprises side forms, an inner form and supporting systems. The side forms comprise common steel formwork bodies and stainless steel plates. The cross sections of the common steel formwork bodies and the cross sections of the stainless steel plates are in a U shape. The stainless steel plates are arranged on the common steel formwork bodies. The cross section of the inner form is in a ring shape. The inner form is arranged in the side forms. The supporting systems are arranged outside the common steel formwork bodies and used for supporting the side forms. According to the formwork for the prefabricated box girder, the stainless steel plates are arranged on the common steel formwork bodies of the side forms, so that the problem that the outer surface of a poured box girder is rugged due to the fact that a common steel formwork is rusted in the pouring process is solved; and the outer surface of the box girder can be smooth and attractive.

Description

technical field [0001] The invention relates to the technical field of bridge prefabricated box girder pouring, in particular to a prefabricated box girder template. 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, hence the name. Its types are divided into single box, multi box and so on. As one of the important structures in bridge engineering, reinforced concrete box girder is divided into prefabricated box girder and cast-in-place box girder according to the concrete pouring method. Among them, the cast-in-place box girder refers to the direct pouring of the box girder on the construction site. The prefabricated box girder is prefabricated in advance in an independent site, and then hoisted after the completion of the bridge substructure. Because prefabricated box girder can effectively avoid construction cross interference, greatly improve ...
