Temporarily-built portable folding footbridge structure for bridge construction

Abstract

The invention provides a temporarily-built portable folding footbridge structure for bridge construction. The temporarily-built portable folding footbridge structure for bridge construction comprisesa main support column and a bearing bolt, wherein ten connection rods are installed at the top of a folding support frame, nine connection rods are installed at the middle part of the folding supportframe, and eighth connection rods are installed at the bottom of the folding support frame; twenty bridge plate support blocks are arranged, and rotationally connected to the outer ends of the ten connection rods which are installed at the top of the folding support frame; and nine bridge panels are arranged, twelve insertion blocks are installed at the bottom of each bridge panel, and the bottomof each bridge panel is installed on the top end surfaces of four bridge plate support blocks. Personnel are facilitated to lay a main body part of a bridge, so that the bridge main body is simple, convenient and rapid to build, and the bridge building time is saved; and during transportation for the bridge, the folding support frame can further be folded through the own characteristic of the folding support frame, so that occupancy for the area of the bridge main body can be greatly reduced, and the personnel are facilitated to carry out transportation and carrying working.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and more specifically relates to a temporary portable folding pedestrian bridge structure for bridge construction. Background technique [0002] With the aging of bridges, the quality of the bridges built in the early stage became more and more unstable, and they needed to be dismantled and rebuilt in time to ensure the safety of people walking; however, bridge construction is more complicated and cannot be built in a short time. It is necessary to build bridges for people to walk during the bridge demolition period to ensure the travel of surrounding residents. [0003] Based on the above, the inventors found that the existing pedestrian bridge structure, such as a portable and quickly installed detachable pedestrian bridge mentioned in the patent application number CN205591098U, includes two towers buried vertically on the foundations on both sides of the river respectively. Frame,...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a temporary portable folding pedestrian bridge structure for bridge construction, to solve the existing pedestrian bridge structure, installation and disassembly are relatively cumbersome, and it is easy to consume a lot of time before the bridge can be built. During the long-term construction process, it is easy to affect the travel of surrounding users; and the size of the device is large, it cannot be folded well when it is disassembled, and it is easy to occupy more storage space, causing difficulties in later transportation and storage.
