[0002] During bridge construction, tie rods are often used to reinforce the formwork to prevent the concrete formwork from expanding. This is especially true for pedestal foundations, small bridge culvert abutments, pier caps, cap beams and precast beams. To ensure that the tie rods can be used multiple times, PVC sleeves can be added to the parts that pass through the concrete body, and the tie rods can be pulled out when the formwork is removed.

[0003] Traditional processes generally use round steel with threads on both ends to process tie rods. The length of the tie rods must be processed according to the size of the template. In areas with limited space on both sides of the pedestal and foundation, the tie rods are often not pulled out equally. Disposable steel tie rods are used, and the exposed tie rod heads are cut off after the template is removed, which wastes materials and affects the appearance of the concrete. Utility model content:

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 As shown, the utility model provides the following technical solutions: an anchoring device for a template tie rod, comprising two templates 1 for tensioning and fixing, and a through hole is passed through and fixed between the two templates 1, a steel strand 2 is passed through the through hole, and a tensioning component is locked and sleeved on the outlet end of the steel strand 2, the side end of the tensioning component is fitted with the template 1, and the two tensioning components can pull the steel strand 2 to pull and fix the two templates 1.

[0017] Specifically, the steel strand 2 is used for pulling, which can effectively prevent the formwork 1 from expanding.
