Description

Technical Field

[0001] The invention relates to the technical field of bridge construction equipment, in particular to an adjustable template device for slope-type piers. Background Art

[0002] High-speed rail construction is inseparable from large bridges. In the process of bridge construction, the use of steel formwork is becoming more and more extensive. Steel formwork has many advantages such as low adsorption force, easy demoulding, small deformation, high turnover times, and fast assembly and disassembly. At the same time, it also reflects excellent performance in many aspects such as strength, rigidity, stability and integrity. Therefore, in the current bridge construction industry, steel formwork is becoming more and more widely used.

[0003] However, most of the existing steel formworks are fixed products and are not easy to change their shapes. The same type of piers with different heights on a bridge also need to be made of a set of steel formworks. In order to ensure the normal progress of the project, the construction unit needs to invest in various types of steel formworks. Therefore, this phenomenon has caused great inconvenience and waste of resources in actual production. In order to reduce the cost of bridge construction and shorten the construction period, new construction methods have gradually emerged.

[0004] A Chinese patent application with publication number CN205529922U discloses a pier column formwork with an adjustable cross-section. The patent provides an adjustable cross-section of the pier column formwork to adapt to the casting of piers with different cross-sectional shapes.
