Prefabricated box girder flange template

Abstract

The invention discloses a prefabricated box girder flange template. The template comprises a template body. A plurality of receding grooves for flange steel bars to penetrate through are arranged in the template body at intervals. Each flange steel bar comprises an arc-shaped end part and extension parts connected with the two ends of the arc-shaped end part respectively; and each receding groovecomprises a sealing part and two receding parts, the two receding parts are located at the two ends of the sealing part and are connected with the sealing part, the arc-shaped end part of each flangesteel bar penetrates through the sealing part so that the two receding parts can be arranged on the two extension parts in a sleeving mode, and the template body, the sealing part and the extension parts form a sealing structure so as to prevent concrete from flowing out. Compared with a wooden flange template, the prefabricated box girder flange template of the structure is capable of being repeatedly used, saving cost and being more environmentally friendly. Compared with a steel flange template, the flange template is good in sealing performance, convenient to install and simple in structure.

Description

technical field

[0001] The invention relates to the field of highway and bridge engineering, in particular to a prefabricated box girder flange template. Background technique

[0002] The prefabricated box girder is composed of three parts: the bottom plate, the web plate and the top plate. The interior is hollow. There are flanges on both sides of the top plate. Important reinforcement for wet joint connections. Therefore, the flange of the box girder needs to be positioned accurately and straight in shape.

[0003] At present, when the box girder is poured, the formwork at the flange is generally made of wood or steel. Using a wooden comb formwork will directly damage the comb formwork during removal and cannot be used repeatedly, which not only wastes wood but also pollutes the environment. When using a steel comb formwork, in order for the U-shaped steel bar to pass through the comb formwork smoothly during assembly, it is often necessary to reserve an escape groove o...

Examples

Embodiment Construction

[0047] In the following, the present invention will be more clearly and completely described by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0048] Such as Figure 1 to Figure 4 As shown, this embodiment provides a prefabricated box girder flange formwork, which is used to install on both sides of the roof reinforcement framework to prevent concrete from flowing out when pouring the reinforcement framework of the box girder 10 . This prefabricated box girder flange formwork 30 includes a formwork body 301 , and a plurality of escape grooves for passing the flange steel bars 102 are arranged at intervals along the length direction of the formwork body 301 . Wherein, the flange reinforcement is a necessary component for strengthening the strength of the wet joint 20 when adjacent box girders are spliced ​​together. The flange reinforcement 102 includes an arc-shaped end 10...
