Abstract: A connector for framing material comprises: a limiting member, a connecting member and a first screw. The hexagon portion of the first screw is received between the first stopping plate and the second stopping plate of the limiting member. The through hole of the connecting member is passed by the first screw to form a pre-lock assembly of the limiting member and the connecting member. The first stopping plate and the second stopping plate parallel to the accepting slot direction to place the limiting member in the U-shaped frame, and then the connecting member is rotated and to make a cross with the U-shaped frame, such that the first screw drives the limiting member to rotate to perpendicular to the U-shaped frame.

Abstract: The present invention discloses a high-strength support assembly structure, which utilizes a fastening cover part that can be slidably sleeved onto a C-type steel and an opening side thereof and a flexible internal stand; the flexible internal stand is placed inside of the C-type steel, and the internal stand and the fastening cover part are correspondingly fastened at the opening side of the C-type steel, such that the opening side of the C-type steel can serve as a connecting end or a bearing side. The present invention also discloses using or stacking a single or a plurality of connecting plates, so as to allow one C-type steel to be correspondingly joined to another C-type steel in order to expand a length thereof, or to adapt the C-type steel for serving as a corner.
