Connected concrete prefabricate combined bin and building method thereof

Abstract

The invention relates to a connected concrete prefabricate combined bin and a building method thereof and aims to solve the problem that traditional slip-form construction is quite high in cost and long in construction period. The connected concrete prefabricate combination bin comprises cylinders (1) and is characterized in that a bin top (2) is connected to the upper portion of each cylinder, each cylinder has an assembled structure, arc-shaped circumferential reinforcing steel bars A (4) and longitudinal reinforcing steel bars A (41) vertical to the arc-shaped circumferential reinforcing steel bars are arranged in a connecting part (3) between two adjacent cylinders, and the rest part of each cylinder is assembled by a group of arc-shaped prefabricated plates (5); the arc-shaped circumferential reinforcing steel bars (4) in the connecting part (3) between the cylinders and arc-shaped circumferential reinforcing steel bars (6) jointly form the circular circumferential reinforcement of the cylinders; cast-in-situ concrete is poured to assembling positions (7) among the arc-shaped prefabricated plates, vertical pouring channels (8) in the arc-shaped prefabricated plates, the connecting part between the cylinder and arc-shaped prefabricate plate joints to form a frame of reinforced concrete columns and beams from bottom to top, and the frame and the connecting part between the cylinders are jointly combined to form the combined bin.

Description

Technical field: [0001] The invention relates to a one-piece storage device and an assembled construction method of the device. Background technique: [0002] Reinforced concrete silos are the main special engineering structures in storage buildings. They are widely used in coal, electric power, ports, mines, food and agriculture and other industries. The group silos have a complex structure, long construction period, difficult construction and high technical requirements. , due to the high value and high risk of innovation, technological progress is very difficult. The traditional construction method of reinforced concrete silos, in which steel bars are bundled layer by layer through formwork casting, is being replaced by slipform technology, and the effect is more significant in the construction of group silos. [0003] However, the sliding form construction not only costs a lot, but also has a long construction period, and the general upward movement speed is only about ...

AI Technical Summary

Problems solved by technology

The height of the concrete silo can easily reach more than 40m. Not only is the height and diameter of the steel silo different from that of the reinforced concrete, but its Achilles’ heel is that the silo wall is thin, and when the temperature difference is large, it is greatly affected by external influences (climate factors such as sunlight) and the temperature fluctuates greatly. Condensation, storage of grains, seasonings and other items that have strict requirements on temperature and moisture, mildew, rot and other phenomena are prone to occur during storage, making it difficult to store grain for a long time

Moreover, due to problems such as corrosion and stress fatigue, there is no way to replace reinforced concrete silos, and the two have been a coexistent mode for many years
