Description
Technical field
The invention belongs to bridge construction construction fields, and in particular to a kind of molding die and its molding work of wide-span case beam
Skill.
Background technique
Box beam is one kind of bridge construction central sill, is reinforced concrete structure, since inside is hollow shape, is similar to chest,
So gaining the name, and single case and more casees are divided into according to hollow quantity again.
According to building relevant regulations, the wet seam of box beam needs to carry out before pouring use dabbing processing, and dabbing area is not
Lower than 80%, therefore dabbing needs to consume great human and material resources, there have been much specification is not conformed to, such as: dabbing
Mode is improper, is stabbed using reinforcing bar point；Plucking, too early dabbing cause concrete loose etc. before concrete initial set, to cause case
Beam detection is unqualified, and wet seam construction is unreliable, influences construction quality and safety.
In addition, common box girder formwork is repeatedly fixed before and after pouring every time, separates, a large amount of people has on the one hand been consumed
On the other hand power also easily causes the damage of template, so that template deformation, influences final product quality, finally, common template uses
Single layer steel plate is easy to influence the solidification of concrete under low-temperature condition, causes box beam surface quality poor, intensity is uneven.
