Description

A shallow round warehouse assembly type warehouse roof and its construction technology

technical field

The invention belongs to the technical field of granary, and more particularly relates to an assembled silo roof of a shallow round silo and a construction process thereof.

Background technique

Shallow round silo, also known as short round silo, the inner radius of the silo is generally greater than 10m, which is a common type of circular grain storage silo located above the ground. The shallow round warehouse has played a certain supporting role in improving grain storage facilities, changing the current situation of grain circulation, solving the shortage of warehouse capacity, ensuring grain safety, and maximizing the economic and social benefits of grain enterprises.

At present, there are usually two methods for the construction and forming of the silo roof of the shallow round silo: one is according to the traditional high-support formwork construction technique, and the other is the construction and forming method of the silo roof using the silo roof truss platform. The traditional high-support formwork construction method has high scaffold erection height, small overall stiffness, large deformation, poor stability, and has construction safety risks; the construction method of the silo roof truss platform has the sequence of start-up time and the length of control time due to manual control. , The difference in the force and speed of the hand zipper wheel, the synchronization is poor, the balance and stability of the orange truss platform during the descending process are also poor, and the force of each hanging point during the descending process of the truss platform will also change. Asynchronous, causing the entire truss platform to tilt and deviate; since the gap between the truss platform and the inner wall of the warehouse is limited, the inclined and deviated truss platform may collide with the inner wall of the warehouse and scratch the inner wall of the warehouse, and even truss in severe cases. Accidents such as overturning.
