Abstract: The present invention discloses a three-dimensional lightweight steel framing system formed by bi-directional continuous double beams. The three-dimensional lightweight steel framing system comprises beams, purlins, columns, wall bodies, floor slabs and lateral resistant mechanism comprises of diagonal support or bracing, wherein the beams are continuous double beams, and the continuous double beams are formed by combination of identical or different continuous single beams, and the continuous single beams are respectively arranged at the both sides of the columns, and the single beams are kept continuous at the junctions with the columns. The three-dimensional lightweight steel framing system simplifies the production of the lightweight steel member, and simplifies the on-site assembly by using bolts and nuts.

Abstract: 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.

Abstract: Disclosed is a three-dimensional lightweight steel framework formed by two-way continuous double beams. The three-dimensional lightweight steel framework comprises beams (1), purlines and/or stringers (16), pillars (2), walls (62, 63), slabs (31) and/or a roof and anti-lateral force bracings (41) and/or pull rods (42), wherein the beams (1) are continuous double beans, and the continuous double beams are formed by combining continuous single beams having the same structure or different structures, and the continuous single beams are respectively arranged at two sides of the outer edges of the pillars (2), and keep continuous and uninterrupted with the pillars (2) at the crosswise junctions; and reinforced lightweight composite slabs can be selected as the slabs (31) completely or partly. The three-dimensional lightweight steel framework simplifies the production of a lightweight steel member, and simplifies the site installation by using bolts to conduct fixing.

Abstract: A square shaped lightweight steel component with reinforced members includes a main body structure (1) and reinforced members (2). The main body structure (1) is a square steel tube integrally molded by a steel plate with certain thickness. One side of the square steel tube is provided with an opening. Angular curled edges (5) are respectively set on two sides of the opening. The reinforced members (2) are fixedly connected with the side of the main body structure (1) having the opening and installed with an interval therebetween.

Abstract: The present invention relates to an integrated localization steel frame used in lightweight steel building. The localization steel frame comprises steel columns (2), bracing members (1), and localization members (3) connecting the steel columns (2) and bracing members (1) through fixing connectors (7). The localization members (3) are casted in concrete ring beams (4). The steel columns (2), bracing members (1) and the fixing connectors (7) are connected together in pre-determined positions. The localization steel frame has proper structure, and is stressed uniformly and cost effective in construction. It can be assembled simply on site and can improve the construction efficiency. Hence it is more suitable for practical application.
