Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to an assembled steel template for bridge construction. Background Art

[0002] Steel formwork is a steel formwork used for concrete pouring and forming. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects due to its multiple uses and beautiful concrete pouring and forming. Steel formwork can replace wooden formwork, which significantly reduces the pore water pressure and air bubble removal in the concrete pressure usually encountered with traditional sealing formworks such as wood, plywood, or steel plates. After the concrete of the steel formwork structure is poured and formed, an ideal rough interface is formed. During bridge construction, steel formwork is usually required for assembly, and then concrete is filled into the steel formwork frame. Therefore, an assembled steel formwork for bridge construction is required.

[0003] The bridge columns produced by the bridge cylindrical steel formwork are built as the base of bridges and viaducts. As the supporting columns of the bridges, the bridges and viaducts can withstand greater pressure and will not collapse. When assembling the bridge cylindrical steel formwork, first, the multiple steel formworks on one side are fixed and connected by a number of bolts and nuts, and then the multiple steel formworks on the other side are fixed and connected by a number of bolts and nuts. Finally, the assembled bridge beam formworks on both sides are spliced ​​together by a number of bolts and nuts to complete the assembly of the steel formworks.

[0004] The disadvantage of the existing method of assembling bridge cylindrical steel formwork is that the steel formworks on both sides need to be assembled by a number of bolts and nuts, and the assembled steel formworks on both sides need to be spliced ​​together by a number of bolts, which makes the assembly inconvenient and increases the workload. Therefore, it is necessary to propose an assembled steel formwork for bridge construction to solve the above-mentioned problems. Utility Model Content
