Description
Technical Field
The invention belongs to the technical field of granaries, and particularly relates to a shallow round granary assembled granary top cover and a construction process thereof.
Background
The inner radius of the shallow round bin, also called short round bin, is generally more than 10m, and is a common round grain storage bin above the ground. The shallow circular bin plays a certain supporting role in improving grain storage facilities, changing the current situation of grain circulation, solving the problem of insufficient bin capacity, ensuring grain safety and realizing the maximization of economic and social benefits of grain enterprises.
At present, two methods for constructing and forming the top cover of the shallow circular bin are generally adopted, namely, one method is according to the traditional high formwork construction technology, and the other method for constructing and forming the top cover of the shallow circular bin is to utilize a truss platform at the top of the bin. The traditional high formwork construction process method has the defects of small overall rigidity, large deformation, poor stability and construction safety risk due to large scaffold erection height; the construction process method of the warehouse top truss platform has the advantages that as the manual control has the differences of starting time, control time, manual sprocket force, speed, and the like, the synchronism is poor, the balance and stability of the citrus rack platform in the descending process are also poor, the stress of each lifting point in the descending process of the truss platform is changed once the lifting points are descended out of synchronism, and the whole truss platform is inclined and deviated; because the clearance between the truss platform and the inner wall of the bin is limited, the inclined and off-set truss platform can collide with the inner wall of the bin and scratch the inner wall of the bin, and even accidents such as truss rollover occur under severe conditions.
Therefore, how to provide a top cover of a shallow circular bin assembly type and a construction process thereof are problems to be solved by those skilled in the art.
