Fabricated platform canopy and installing method thereof

Abstract

The invention discloses a fabricated platform canopy and an installing method thereof. The fabricated platform canopy comprises a concrete foundation, a fabricated prefabricated concrete column, a connecting joint of the foundation and the prefabricated concrete column, a connecting joint of the prefabricated concrete column and a prefabricated concrete T-shaped beam, the prefabricated concrete T-shaped beam, a prefabricated concrete slab connecting joint, a connecting joint of the prefabricated concrete T-shaped beam and a prefabricated concrete slab, a connecting joint of the prefabricated concrete T-shaped beam and a prefabricated concrete slab middle beam and the prefabricated concrete slab. The fabricated platform canopy and the installing method thereof have the beneficial effects that the column, the beams and the slab of the platform canopy are all prefabricated in a factory, and the construction efficacy can be greatly improved; the column and the foundation adopt traditionalsleeve connection, the seismic performance is equal to the seismic performance of a cast-in-place structure; the column and the beams are connected, steel bar holes are reserved in the beams, column steel bars are inserted into the holes and are anchored by anchor bolts, and the seismic performance meets related standard requirements; and the beams and the slab are welded by adopting embedding I-shaped steel, and the seismic performance meets the related standard requirements; and the structure is simple, and the manual operation can be greatly reduced.

Description

technical field [0001] The invention relates to a platform canopy, in particular to an assembled platform canopy and an installation method thereof, belonging to the technical field of concrete structures in structural engineering. 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, which is not only labor-intensive, but also the construction site is chaotic and the building materials...

AI Technical Summary

Problems solved by technology

Due to the extremely high requirements on the mix ratio of clear-water concrete, once concrete with different mix ratios is mixed in the process of mixing and transportation, there will be different degrees of color difference after pouring, and the clear water effect of concrete is difficult to guarantee

2. High quality requirements for raw materials

Due to the relatively long construction period of the canopy, it is difficult to achieve a high degree of consistency in the batches and physical properties of raw materials, and the physical properties also change with the change of temperature. ensure

3. High requirements for workers to operate

Since the technical problems of cast-in-place clear-water concrete are difficult to solve, and are restricted by construction conditions and the technical level of on-site construction personnel, even if the quality of the formwork and concrete meets the engineering requirements, the clear-water effect after construction cannot be fully guaranteed

4. In order to achieve the expected effect of fair-faced concrete, the requirements of all links in the construction process have been greatly increased, and the corresponding costs have increased to varying degrees, and finally the total cost has increased
