A stacked mechanized bridge structure

Abstract

The invention discloses a stacked mechanized bridge structure. Based on a traditional mechanical bridge, the bridge body is divided into an upper bridge body and a lower bridge body. Layer clapboard structure, each layer clapboard structure is composed of longitudinal and transverse clapboards staggered; in the length direction, it is a segmented modular bridge structure, and the bridge between two adjacent bridges is connected by connecting pieces when in use. Consolidated, disassembled for shipping. In the use state, the columns below the upper bridge body are fixedly connected to the columns above the lower bridge body in a one-to-one correspondence; in the transport state, the segmented bridge bodies of the upper bridge body and the lower bridge body are arranged in a staggered stacking arrangement in the height direction . The stacked mechanized bridge structure of the present invention can not only switch the working state and the transportation state conveniently, but also can reduce the overall height of the mechanized bridge during transportation through connection.

Description

technical field [0001] The invention belongs to the field of mechanized bridges, and in particular relates to a stacked mechanized bridge structure, which is especially suitable for the field of disaster relief and emergency rescue which requires reducing transportation and maintenance costs. Background technique [0002] During the use of mechanized bridges, corresponding supporting transportation facilities are required. Most of these transportation equipment are modified from mature standard equipment on the market, and are subject to the design standards of highways and bridge openings in my country. The width of the bridge structure that these transportation equipment can carry , High are limited. This phenomenon contradicts the fact that the higher the height of the mechanized bridge, the better the bearing capacity. [0003] In order to solve this problem, a large amount of transportation equipment is often required in the process of disaster relief and rescue, which ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of the existing mechanized bridge transportation facilities, such as large demand, limited height of the bridge body that can be transported, high cost of use and maintenance, etc., the present invention provides a stacked mechanized bridge structure that is convenient for transportation. The structure can not only switch between the working state and the transportation state conveniently, but also reduce the overall height of the mechanized bridge during transportation through the connection
