Abstract

The invention provides a stamped metal connecting plate and a truss. The plate body is a thin metal plate with screw holes distributed on, and the upper plates used to connect with a chord and the lower plates used to connect at least one web member to form an integrated stamped piece, wherein the two side edges of the lower plates are provided with kidney and arc-shaped outward flanging; the top terminal of the arc-shaped outward flanging intersects with the bottom edge of the chord; the bottom terminal of the arc-shaped outward flanging intersects with the lateral edge(s) of the web member(s). A stamped groove is arranged from the upper plates to the lower plates of the plate body near the center of each web member. The truss is formed by stamped connecting plates, wherein the two stamped connecting plates are clamped on the pros and the cons of the connecting nodes of the truss; the two upper plates are connected fixedly with the chord by self tapping screws or bolts; the lower plates are connected fixedly with one to three web members by self tapping screws or bolts. The invention greatly enhances the bearing capacity and the rigidity of the truss, the manufacture and the assembly are convenient.

Description

(1) Technical field [0001] The invention relates to a node connecting metal plate and a truss, in particular to a stamping formed node connecting metal plate and a truss. (2) Background technology [0002] Cold-formed thin-wall steel trusses have the characteristics of reasonable stress, light weight, good seismic performance, convenient production, and fast construction speed. In recent years, they have been widely used in light steel keel system residences, office buildings and small and medium-span buildings. The rods in traditional cold-formed thin-walled steel trusses are generally square (rectangular) pipes, round pipes, angle steels and channel steels within 6mm thickness. The connection methods of the rods are welding, bolt connection or self-tapping screw connection. [0003] Welding is a direct connection method between cold-formed thin-walled steel truss members. Although this connection method has a large bearing capacity and does not require a contact plate, the weld...
