Precast concrete n-shaped beam for fabricated concrete canopy of railway station

Abstract

The invention discloses a precast concrete n-shaped beam for a fabricated concrete canopy of a railway station. The precast concrete n-shaped beam comprises a left side beam, a middle beam, a right side beam, an edge beam bracket support, a left bracket beam, a middle beam bracket support, a middle bracket beam, a right bracket beam, a support cushion block, a left side beam column pier and a right side beam column pier. A main structure of the concrete n-shaped beam is formed by the left side beam, the middle beam, the right side beam, the left side beam column pier and the right side beam column pier. The precast concrete n-shaped beams are symmetrically arranged along the longitudinal axis and the transverse axis. The precast concrete n-shaped beam can be machined in a factory and transported to the site to be hoisted and mounted, the industrialization degree is high, and field mounting is convenient; and the construction field is clean and tidy, the construction period is short, good economic benefits and social benefits are achieved, and the precast concrete n-shaped beam is suitable for popularization and use.

Description

technical field [0001] The invention relates to a prefabricated concrete π-shaped beam, in particular to a prefabricated concrete π-shaped beam used for an assembled concrete canopy at a railway passenger station, and belongs to the technical field of concrete structures. Background technique [0002] With the rapid development of China's high-speed railway, high-speed railway stations have sprung up like mushrooms, and small and medium-sized high-speed railway station buildings are blooming everywhere. The platform canopy is one of the essential buildings of the high-speed rail station as a shed for passengers to shelter from the wind and rain when getting on and off the train. [0003] Canopy construction generally adopts the method of on-site construction, that is, from erecting scaffolding, supporting formwork, binding steel bars to pouring concrete, most of the work is done manually at the construction site. On the one hand, the labor intensity is high, the construction...

Problems solved by technology

[0003] Canopy construction generally adopts the method of on-site construction, that is, from erecting scaffolding, supporting formwork, binding steel bars to pouring concrete, most of the work is done manually at the construction site. On the one hand, the labor intensity is high, the construction site is chaotic, and the building The consumption of materials is large; on the other hand, there is a lot of construction waste generated on site, and at the same time, it has a great impact on the surrounding environment
