Embodiment Construction

[0008] As shown in the figure, the widening formwork of the bridge pier includes a U-shaped inner cavity composed of an end formwork 1 and two side formworks 2. The end wall purlin 3 and the side wall purlin 4; the rear ends of the side wall purlin 4 on both sides are connected to the two ends of the end face wall purlin 3, and the front end of the side wall purlin 4 protrudes from the side template 2, and the extension length is the same as that of the to-be-widened The width of the original pier body is compatible; the front ends of the side purlins 4 on both sides are connected and fixed by tie bolts 5 . Both the end purlins and the side purlins are made of double channel steel.

Abstract

The invention relates to a bridge construction technology, in particular to a bridge pier body widening template. The bridge pier body widening template comprises a U-shaped inner cavity which is composed of an end face template and two side face templates. The outer side of the end face template and the outer sides of the side face templates are connected with an end face surrounding purlin and side face surrounding purlins respectively, wherein the end face surrounding purlin and the side face surrounding purlins rank in parallel from bottom to top. The rear ends of the side face surrounding purlins on the two sides are connected to the two ends of the end face surrounding purlin, the front ends of the side face surrounding purlins stretch out of the side face templates, and the stretching-out length is matched with the width of an original pier body to be widened. The front ends of the side face surrounding purlins on the two sides are connected and fixed through stay bolts. Pouring cavities can be formed in the bridge pier body widening construction process, and the bridge pier body widening template is simple in structure, low in cost, convenient to construct and operate and short in construction period.

Description

technical field [0001] The invention relates to a bridge construction technology, in particular to a bridge pier body widening template. Background technique [0002] In the reconstruction of the bridge, it is necessary to widen the original pier body. The traditional construction method needs to set up complex construction facilities, which not only has high construction cost, but also has a long construction period. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bridge pier widening formwork that can be used in bridge pier widening construction, has a simple structure, is convenient to use, and has low construction cost. [0004] The bridge pier body widening formwork of the present invention includes a U-shaped inner cavity composed of an end formwork and two side formworks, and the outer sides of the end formwork and the side formwork are respectively connected with end surface purlins and side purlins arr...
