Abstract

The invention relates to a connection system, in particular to an assembled connection system of a box-shaped single-layer reticulated shell, an assembly method and a design method thereof, and belongs to the field of steel structures. Including end plate I and end plate II, end plate I and end plate II are connected and fixed by several sleeve bolts; installation operation holes are formed between end plate I and end plate II; end plate I, sleeve bolts, installation operation holes and End plates II combine to form a connection system. This structure is easy to install and has high versatility.

Description

technical field [0001] The invention relates to a connection system, in particular to an assembled connection system of a box-shaped single-layer reticulated shell, an assembly method and a design method thereof, and belongs to the field of steel structures. Background technique [0002] Box-section rod is a general term for all kinds of thin-walled square tubes, rectangular tubes or welded box-section rods made by cold bending, hot rolling and welding processes, and has extremely excellent cross-sectional properties. From the perspective of mechanical properties, it has better one-way bending stiffness than the ring section, and has better axial torsional stiffness and weak axis bending stiffness than the I-shaped, groove-shaped, and Z-shaped open sections; In terms of appearance, it has less one-way line of sight blocking than the circular section, and is cleaner than the open section; in terms of weather resistance, it has the same airtightness as the circular section, wh...
