Straddle type monorail steel-concrete track beam bridge floor pouring formwork and bridge floor pouring method

Abstract

The embodiment of the invention discloses a straddle type monorail steel-concrete track beam bridge floor pouring formwork and a bridge floor pouring method.The formwork is composed of formwork vertical belts, side formworks, linear strips, vertical adjusting bolts, upper and lower rib plates, fixing plates, split bolts, transverse adjusting bolts, lower adjusting bolts and the like. A rib plate arranged at the top of a template vertical belt is adopted as a counter-force seat, an adjusting bolt and a base plate act on an opposite-pull screw rod, and a long round hole in a side template is matched, so that the side template is kept fixed when a linear strip is adjusted, and the linear strip is released to deform through a groove in the middle of the linear strip; and the vertical surface line shape of the top surface of the track beam can be adapted through the vertical adjusting bolt. The problems that a bridge deck concrete part requires high manufacturing precision, and the line shape of a beam body is difficult to control are solved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of bridges, in particular to a bridge deck pouring formwork and a bridge deck pouring method of a straddle-type monorail steel-concrete track girder bridge. Background technique [0002] The track beam is both a track and a load-bearing beam. The "beam-rail integration" characteristic of straddle monorail traffic makes it highly demanding on the linear accuracy of the track beam. Any error beyond the limit may lead to the scrapping of the product and cause engineering losses. . The construction of track beams is easily affected by the environmental conditions in each link, so the quality control requirements in the construction process are relatively high, and the quality control of each link is the basic guarantee for the smooth completion of the project. [0003] The straddle type monorail traffic steel-concrete combined track beam has a large load-carrying capacity, relatively l...

Problems solved by technology

[0006] For this reason, the embodiment of the present invention provides a straddle-type monorail steel-concrete track girder bridge deck pouring formwork and a bridge deck pouring method to solve the problem of the complexity and high-precision requirements of the track beam alignment in the prior art, which cannot be adopted by conventional methods. The formwork system and manufacturing process of concrete beams lead to the problems of low manufacturing precision of the bridge deck and difficulty in controlling the linear adjustment of the beam body
