A kind of segmental box girder short-line matching control and prefab construction method

Abstract

The invention discloses a segmental box girder short-line matching control and prefabrication construction method, the steps are as follows: step 1, divide the beam field into functional areas; step 2, make end beams in the beam manufacturing area; step 3, install cast-in-place beams Formwork; step 4, put in the bundled steel skeleton and control the checking position; step 5, pour concrete into the cast-in-place beam formwork; step 6, use the cast-in-place beam as a matching beam for cyclic prefabrication; from this until the pouring is completed, the beams used body; Step 7, put the completed beam body into the beam storage area for maintenance; the present invention divides the beam field into functional areas, which can effectively organize the on-site construction flow and ensure construction efficiency; through the pedestal beam system, measurement control system and The joint setting of the support adjustment platform can not only install and adjust the precise position, but also can control in real time; through the design of the shear key, it can ensure the linear connection in the later stage; the setting of different spraying facilities can be effective and the later maintenance can be carried out.

Description

technical field [0001] The invention belongs to the technical field of manufacturing and construction of segmented box girder, and particularly relates to a short-line matching control and prefabrication construction method of segmented box girder. Background technique [0002] With the development of road construction, bridges have been paid more and more attention as an important component of roads. In bridge construction, due to its unique composition method, the construction of viaduct roads used to be constructed with full-body supports. However, this method is complicated to operate, consumes labor and construction costs, and the construction speed cannot meet the design requirements. As a result, the prefabricated segmented box girder avoids the above shortcomings and achieves great development. In the prefabrication of segmental box girder, long-line matching prefabrication is usually used, but this method has the disadvantages of high site requirements, inflexible ...
