Description
Technical Field
The invention relates to a platform canopy, in particular to an assembled platform canopy and an installation method thereof, and belongs to the technical field of concrete structures in structural engineering.
Background
Along with the rapid development of China high-speed railways, high-speed rail stations appear like spring bamboo shoots after rain, and medium and small high-speed rail station houses bloom more frequently. The platform canopy is used as a canopy for shielding wind and rain when passengers get on or off the bus, and is one of essential important buildings of the high-speed railway station.
The rainshed construction generally adopts a site construction mode, namely pouring from scaffold erection, formwork erection and steel bar binding to concrete, most of work is completed manually on a construction site, the labor intensity is high, the construction site is disordered, the consumption of building materials is high, more building wastes are generated on site, and meanwhile, the surrounding environment is greatly influenced. The method has the advantages of neat construction site, short construction period and incomparable application prospect of mass production in site construction mode.
At present, the high-speed railway platform canopy adopts bare concrete mostly, and the quality requirement of the bare concrete is high, and the following defects exist, namely, 1, special stirring and transporting equipment is required to be equipped. As the bare concrete has extremely high requirements on the mixing proportion, once the concrete with different mixing proportions is mixed in the stirring and transporting processes, the color difference with different degrees can appear after the pouring is finished, and the clean water effect of the concrete is difficult to ensure. 2. The quality requirement on the raw materials is high. The quality of each batch of various raw materials of the concrete should be highly stable, and the properties of the raw materials in the construction process of the bare concrete must be completely consistent. Because the construction period of the awning is relatively long, the batches and physical properties of raw materials are difficult to achieve high consistency, and the physical properties are also changed along with the change of air temperature, if the construction is performed by adopting a cast-in-situ method, the clean water effect of concrete is difficult to ensure. 3. The operation level of workers is high. The operation level of workers directly influences the appearance quality of the bare concrete, the higher level of operators are needed in the construction of the bare concrete structure, the workers are definitely separated, and the workers cannot be replaced in the whole construction period, because each construction detail influences the appearance effect after the construction is finished, and the appearance effect after the concrete is molded is different when the concrete vibrating hand is taken as an example and the vibrating time between two vibrating parts is different. Because the cast-in-situ bare concrete technical problem is difficult to solve and is limited by construction conditions and technical levels of on-site constructors, even if the quality of the template and the concrete meet engineering requirements, the clean water effect after construction is not completely ensured. 4. In order to achieve the expected effect of the bare concrete, the requirements of all links in the construction process are greatly improved, the corresponding cost is increased to different degrees, and finally the total cost is improved.
