Various implementations described herein are directed to a load bearing ledger fitting, a modular header beam, a perimeter safety deck, a multi-purpose bearing plate, and a mega-shore bearing plate of an integrated construction system.

A volumetric modular unit constructed at a modular unit factory and shipped assembled to a modular building project site is disclosed. A modular building constructed from shipped volumetric modular units is also disclosed. Features of a volumetric modular unit and modular building are designed to account for and leverage traditional building practices. Shipping constraints often dictate volumetric modular unit design constraints. The volumetric modular unit and modular constructed building addresses both design needs and shipping constraints to leverage more economical resources available at a volumetric modular unit manufacturing plant.

A strut and method using same is provided. The strut comprises a body member having a longitudinal axis, a first end and a second end. A first gripping member is connected to the first end of the body member. The first gripping member comprises a first plate for engaging a first structural engagement member. A second gripping member is connected to the second end of the body member. The second gripping member comprises a second plate for engaging a second structural member. The body member of the strut extends in a direction to intercept each of the first and second plates.

A light steel roof truss with a structure of a double continuous beam includes structural beams (1) and structural columns (2). The structural beam (1) consists of a pair of continuous beams, and the structural column (2) is located between the two continuous beams through locating holes (4). Thereby the stability of a support structure of the roof truss is increased, and the supporting members of the roof truss can be connected conveniently.

A combined member, comprising a communication rod (1) and a connecting rod (2), wherein the connecting rod (2) comprises a rod body (2.1) and a connector (2.2), the connector (2.2) being a fastening connector (3) or a sleeving connector (4), the rod body (2.1) of the connecting rod (2.1) and a rod body of the communication rod (1) being of a strip-shaped structure, the connecting rod (2) being connected to the communication rod (1) by the fastening connector (3) or the sleeving connector (4), the axis of the connecting rod (2) intersecting that of the communication rod (1) connected thereto. The combined member has the advantages of high bearing capacity, and convenient construction.
