Sound barrier foundation and box girder integrated pouring template

Abstract

The invention discloses a sound barrier foundation and box girder integrated pouring template. A sound barrier foundation outer template is formed in the manner than a box girder outer template overall extends upwards and is heightened. A sound barrier foundation inner template adopts a rectangular steel plate as long as the sound barrier foundation outer template. The sound barrier foundation outer template and the sound barrier foundation inner template are connected through multiple n-shaped connecting components arranged at equal intervals in the length direction. Each n-shaped connectingcomponent is formed in the manner than two pieces of oppositely-arranged strip-shaped angle steel are spliced by being combined with bolts after top face stacking, wherein the vertical face of one piece of strip-shaped angle steel and the vertical face of the sound barrier foundation outer template are welded, and the vertical face of the other piece of strip-shaped angle steel and the vertical face of the sound barrier foundation inner template are welded. The grinding procedure of the outer side of a sound barrier foundation is omitted, the aerial near-edge work is reduced, and safety risksare reduced; and the number of times of template mounting and concrete pouring is reduced, construction time is saved, the input of labor force is reduced, and work efficiency and engineering benefitsare improved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, in particular to an integrated pouring formwork for a sound barrier foundation and a box girder. Background technique [0002] Sound barriers are widely used in municipal transportation facilities such as urban rail transit and expressways, which can absorb and reduce noise and reduce the impact of traffic noise on urban areas. [0003] Taking bridges as an example, the currently widely used technology is that after the box girder is poured and hardened to a certain strength, then steel bars are bound on the flange of the box girder, the sound barrier foundation formwork is installed, and the sound barrier foundation is poured. There are two main defects. One is that the joint between the sound barrier foundation and the box girder is easy to form cement slurry blocks on the facade due to the leakage of formwork, and there is a safety risk of high-altitude edge operations when grindin...

Problems solved by technology

There are two main defects. One is that the joint between the sound barrier foundation and the box girder is easy to form cement slurry blocks on the facade due to the leakage of formwork, and there is a safety risk of high-altitude edge operations when grinding the cement slurry blocks on the exterior facade in the later stage; the other is that The construction of the sound barrier foundation needs to be carried out after the construction of the box girder is completed, which increases the construction process and construction period, increases the investment of time and labor, and increases the project cost
