Segmental modular rapid assembly bridge

Abstract

The invention relates to a sectional type modularization rapid assembled and spliced bridge which comprises springboard bridge sections (1) and standard bridge sections (2). Each springboard bridge section (1) comprises a top board (11), a web (12), a bottom board (13), a pressure bearing interlocking end board (14) and a negative head and positive head connecting lug board (15). Each standard bridge section (2) comprises a top board (21), a web (22), a bottom board (23), a pressure bearing interlocking end board (24) and a negative head and positive head connecting lug board (25). The springboard bridge sections (1) and the standard bridge sections (2) are fixedly connected through the pressure bearing interlocking end boards (14), the negative head and positive head connecting lug boards (15), the pressure bearing interlocking end boards (24) and the negative head and positive head connecting lug boards (25). Every two standard bridge sections (2) are fixedly connected through the pressure bearing interlocking end boards (24) and the negative head and positive head connecting lug boards (25). Every two assembled and spliced bridges are fixedly connected through a transverse connecting arm (3). The sectional type modularization rapid assembled and spliced bridge has the advantages of being convenient to transport, flexible to assemble and splice, capable of being erected rapidly, and particularly suitable for releasing emergencies and disasters. The webs are made of corrugated steel, and the bottom boards are made of laminated composite materials.

Description

technical field [0001] The invention relates to a rapid assembly bridge, in particular to a segmental modular rapid assembly bridge. Background technique [0002] Earthquake, as a sudden natural disaster, has the characteristics of short occurrence time, wide spread and serious disaster degree. Destructive earthquakes often cause bridges to be destroyed and traffic to be interrupted, which brings many obstacles to post-earthquake emergency rescue work. Highway traffic is an important channel for earthquake emergency rescue personnel and material transportation, and is the lifeline of traffic in disaster areas. Quickly rushing through the lifeline interrupted by the earthquake is an important content and a key link in the rescue and relief work. In the work of rushing through the lifeline, it is often necessary to use the method of building a temporary bridge to cross major obstacles such as interrupted bridges or roads. [0003] Existing temporary temporary bridges are ma...

Problems solved by technology

[0005] On the whole, the existing temporary bridge technology is characterized by many and complex rods, heavy self-weight, time-consuming and laborious construction and erection, and is generally not suitable for emergency rescue in post-earthquake emergency situations.
