Abstract

The invention provides a reinforced Bailey sheet steel arch connection structure and its assembled connection method. The reinforced Bailey sheet steel arch frame includes a number of assembled joints, and the assembled section is composed of a number of reinforced Bailey sheet connections. Embedded parts are provided, and the assembly section at the end is connected with the embedded part through the connecting arch foot section, and the assembled sections are connected through the connecting section. The structure can make the reinforced Bailey steel arch frame easy to install and easy to control the accuracy of the installation position, and is suitable for the assembled connection of the reinforced Bailey arch support frame that requires a higher bearing capacity.

Description

technical field [0001] The invention relates to the technical field of cast-in-situ reinforced concrete arch bridge Bailey sheet steel arch frame, in particular to a reinforced Bayley sheet steel arch frame connection structure and an assembly and connection method thereof. Background technique [0002] Reinforced concrete arch bridges have many characteristics such as low cost and good durability, and are widely used, and are especially suitable for construction in high mountains and valleys. The construction technology of steel arch frame cast-in-place arch bridges is a common construction method for reinforced concrete arch bridges. It has fast construction speed, The concrete quality of the arch ring is easy to control and so on. There are many types of steel arch structures, and reusable Bailey sheets are often used in engineering to form arches. Since the rectangular trusses with a size of 3m×1.5m per piece of Bailey do not conform to the arc or catenary shape of the ...
