The widening formwork of the bridge pier body 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 purlins and side purlins arranged in parallel from bottom to top; The rear ends of the side purlins on both sides are connected to the two ends of the end purlins, and the front ends of the side purlins protrude from the side formwork, and the protruding length is suitable for the width of the original pier body to be widened; the front ends of the side purlins on both sides Fastened by tie bolts. The invention can form a pouring cavity in the widening construction of the bridge pier body, has simple structure, low cost, convenient construction operation and short construction period.

Description

Bridge pier widening formwork

technical field

The invention relates to a bridge construction technology, in particular to a bridge pier body widening template.

Background technique

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

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.

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 arranged in parallel from bottom to top The rear ends of the side purlins on both sides are connected to the two ends of the end face purlins, and the front ends of the side purlins protrude from the side formwork, and the extension length is adapted to the width of the original pier body to be widened; the side purlins on both sides The front end of the purlin is connected and fixed by tie bolts.

Both the end purlins and the side purlins are made of double channel steel.

The invention can form a pouring cavity in the widening construction of the bridge pier body, has simple structure, low cost, convenient construction operation and short construction period.

Description of drawings

Fig. 1 is a schematic view of the side structure of the present invention.

detailed description

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.
