[0001] The present invention belongs to the technical field of the construction of the conical top of a shallow silo, and specifically relates to a node device for connecting a Bailey truss and a support falsework. Background Art

[0002] "The granaries of the world" should be substantial, and more importantly, they should be fresh, save grain, reduce losses, and reduce carbon emissions. Only by doing a good job in warehousing science and technology can we better win the grain purchase battle and hold the "Chinese rice bowl" firmly. By increasing investment and promoting the construction of warehousing facilities, China has basically formed a grain purchase and storage guarantee system that adapts to grain production, storage, and circulation. At present, the intact storage capacity of national standard grain warehouses exceeds 700 million tons, an increase of 36% compared with 2014.

[0003] With the increase in national investment in the construction of warehousing facilities, the three-dimensional storage industry represented by large-span shallow silos has developed rapidly. The main structure of the shallow silo is generally high in height, large in span, and large in volume, and most of the structures are sub-projects with relatively large risks exceeding a certain scale. Therefore, higher requirements are needed for the construction of the main structure of the shallow silo, considering safety, functionality, practicality, and convenience.

[0004] The structure of the shallow silo is mainly divided into the construction of the silo wall and the conical top. Among them, in the construction of the conical top, the erection of the working platform was earlier supported by an umbrella truss system, with poor stability and uneven stress.

Each independent single piece is connected to form a stressed truss, and after being installed with the support falsework, it forms a support whole, which can fully meet the expected safety and durability, and is also convenient for maintenance and repair, with reasonable cost.

[0006] However, multiple existing Bailey trusses cannot be effectively connected to form an integral truss when in use, and it is not convenient to stably install them with the support falsework. Therefore, the present invention provides a node device for connecting a Bailey truss and a support falsework. Summary of the Invention
