Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to an assembled combined structure silo node. Background Art

[0002] Reinforced concrete silos are the main special engineering structures in storage buildings and are widely used in other industries such as coal, electricity, ports, mining, food and agriculture. They have complex structures, long construction periods, high construction difficulty and high technical requirements. Due to their high value, high innovation risks and very difficult technological progress, the traditional construction method of reinforced concrete silos, which uses layers of bundled steel bars and cast them through formwork, is being replaced by slipform technology.

[0003] However, slipform construction has high requirements for construction technology and management. Operators need to have professional knowledge, and the preparation work before construction is complicated, and there are high requirements for the formulation and implementation of construction plans. A larger space is required to install slipform equipment. In addition, severe weather conditions (such as strong winds and low temperatures) may affect the progress and quality of slipform construction. Slipform construction is not only very expensive, but also has a long construction period. The general upward movement speed is only about 30 centimeters per cycle. The overall hardness requirements must be met before it can be demolded, which occupies a lot of cost resources. The overall molding not only has high construction costs, but also the eccentricity is difficult to correct during the sliding process; and long-term humidity after construction, it takes a relatively long time or even several months for the humidity problem to gradually improve. If food, seasonings and other items with strict moisture requirements are stored, quality problems are more likely to occur, and the commissioning time is delayed even more.

[0004] Prefabricated silos are modern storage facilities. Compared with traditional building warehouses, prefabricated silos have many significant advantages, such as faster construction speed, better sealing performance, lower maintenance costs and higher space utilization. However, the nodes in existing related research are mostly welded, and the quality of welds is difficult to stably control. Stress concentration is prone to damage or destruction at welds. In addition, such nodes have poor deformation capacity, low node assembly level, and are difficult to repair. Therefore, it is extremely important to study a prefabricated node connection form that is easy to construct and economical in cost. Utility Model Content

A double steel plate composite structure silo wall is correspondingly welded in a U-shaped connector, and the two ends of the intermediate connection component are respectively fixed on the rear plate of a U-shaped connector, so that the two U-shaped connectors are fixedly connected.

[0016] 2. The double steel plate composite silo wall of the utility model is prefabricated in the factory and welded with the U-shaped connector.
