Background

In the construction of a bridge structure, in order to ensure that the formworks 4 on the two sides are firmly fixed during formwork installation, a form of a counter pull rod 1 is generally adopted. As shown in figure 1, holes are punched at corresponding positions of the template 4 for penetrating the pull rods 1. If the template 4 is formed by assembling a plurality of templates, the back edge 2 is adopted to reinforce the outside of the template 4 so as to form a whole. The back edge 2 is made of double-side wood or double-steel pipe, the opposite pull rod 1 penetrates through the middle of the back edge and the outer side of the back edge is fastened by a fastener 3. If a single integral template 4 is adopted, the back edge 2 is not required to be arranged on the outer side, and the pull rod 1 is directly penetrated through the template 4 penetrating hole. When the opposite pull rods 1 need to be repeatedly used, PVC (polyvinyl chloride) sleeves are usually arranged in the structure of the template 4 corresponding to the opposite pull rods 1, and after concrete pouring and template dismantling are completed, the opposite pull rods 1 are pulled out for next use. If the pull rod 1 is not repeatedly used, the exposed part of the pull rod 1 is cut off when the template 4 is removed; the PVC casing pipe on the structure surface of the template 4 or the end part of the cut counter-pull rod 1 needs to be polished into a groove shape and filled with cement paste with the strength not lower than that of the structure concrete.

The prior art has the following disadvantages:

1) when the pull rod 1 is used for fixing the template 4, the template 4 needs to be punched, so that the template 4 is damaged.

2) After the form is removed, the position of the pull rod 1 needs to be polished and repaired by cement paste, so that the position is inconsistent with the color of structural concrete, and the appearance effect is influenced.

3) When the pull rod 1 is designed to be repeatedly used, a PVC sleeve needs to be penetrated in advance, otherwise, the pull rod 1 needs to be cut off, and the two modes cause material waste.
