Embodiment Construction

[0049] The present invention as figure 1 , 2 , 3, 4, 5, 6, 7, and 8.

[0050] The arched structure of the Bailey girder of the high-span bridge includes pier 2 on both sides, a plurality of supporting columns 1 and beams, and a plurality of supporting columns 1 and beams are used to set up a fixed bracket of different heights between the pier 2 on both sides, each The top of the two supporting columns 1 is an inclined plane, and a plurality of inclined planes form a basic arc surface, wherein a standard Bailey beam 3 is erected on each inclined plane, and a Bailey beam 3 is used between the standard Bailey beam 3 and the pier 2. Beams one and four are connected, and the standard Bailey beams 3 are connected with Bailey beams two and five; the Bailey beams are assembled into a plurality of interconnected inclined planes, and arc-shaped supports 11 are arranged on the inclined planes, and on the arc-shaped supports 11 Set up casting formwork 9 again and make it become arched s...

Abstract

The invention provides an arching structure of high large-span bridge bailey beams and a construction method thereof. A fixed bracket is erected between piers on two sides through a plurality of supporting vertical columns and beams; an inclined plane is formed at top ends of every two supporting vertical columns; a plurality of inclined planes form a basic cambered surface; a standard bailey beam is erected on each inclined plane; the standard bailey beams are further connected with one another; an arc bracket is further erected on each inclined plane; casting templates are further erected on the arc brackets, so that the arching structure is formed; the preset height difference is formed through the supporting vertical columns; after the erecting of the supporting vertical columns, the arc requirement is initially achieved; the bailey beams are assembled into a plurality of inclined planes which are connected with one another; the bailey beams are erected on the inclined planes; one arc bracket is further arranged on each inclined plane. The method has the advantages of low construction difficulty, simple construction technology, convenience in operation, high safety factor and the like, and can be widely applied to construction of large span bridges, such as arch bridges and arch rings, with radian at bottoms.

Description

technical field [0001] The invention relates to the assembly of Bailey beams in the field of bridge construction, in particular to the arching structure of Bailey beams of high and long-span bridges and a construction method thereof. Background technique [0002] In the cast-in-place construction of bridge columns, in order to make the bridge line and rigidity meet the requirements, in the case of flat terrain, full columns or steel pipe scaffolding are generally used for erection. Advantages: the construction is less difficult and easy to operate; limitations: the construction height and span are limited. [0003] When the terrain of the construction site has large undulations and the construction height of the structure is high, the steel pipe column + Bailey frame is usually used for construction. Advantages: large material rigidity, large construction span; Disadvantages: construction hoisting is limited to plane operations. [0004] "Shanxi Architecture" July 2008 iss...
