Abstract
A light steel keel with a strengthened flute comprises a C-shaped vertical keel, a U-shaped transverse keel and a C-shaped cladding keel, wherein two transverse strengthened flutes are arranged at a direction of bottom surfaces of the C-shaped vertical keel and U-shaped transverse keel strengthen to the keel; vertical impress strips which are arranged at accordant interval are arranged in the flute in the direction vertical to the stretching direction vertical of the keel; a transverse strengthened flute is arranged on the bottom surface of the C-shaped cladding keel along the stretching direction of the keel; vertical impress strips which are arranged at accordant interval are arranged in the flute in the direction vertical to the stretched direction of the keel; and two transverse pressing slots are respectively arranged at the direction of the two side faces stretching to the keel. The utility model enhances transverse and vertical hardness of the light steel keel so that the light steel keel is firm, durable and difficult to deform, thereby effectively improving the bearing and anti-impact abilities of the light steel keel.
Description
Technical field
The utility model relates to a kind of lightgage steel joist, relates to a kind of groove strong lightgage steel joist that adds in particular.
Background technology
Lightgage steel joist national standard GB 11981-2008 for building has had higher requirement to lightgage steel joist, and there is certain defective in lightgage steel joist commonly used at present on hardness, intensity, is unfavorable for actual constructing operation.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes existing product, and a kind of sturdy and durable, on-deformable groove strong lightgage steel joist that adds is provided.
In order to reach the purpose of foregoing invention, the utility model adopts following technical scheme: the described groove strong lightgage steel joist that adds comprises C type centre keel, horizontal keel of U type and C type clad can keel, described C type centre keel, the bearing of trend that keel are prolonged in the bottom surface of the horizontal keel of U type is provided with two transversely strengthening grooves, vertical keel bearing of trend is disposed with consistent at interval vertical impression bar in the groove, C type centre keel, the two sides of the horizontal keel of U type are prolonged the keel bearing of trend and respectively are provided with three horizontal indents, the bearing of trend that keel are prolonged in the bottom surface of described C type clad can keel is provided with a transversely strengthening groove, vertical keel bearing of trend is disposed with consistent at interval vertical impression bar in the groove, and two sides are prolonged the keel bearing of trend and respectively are provided with two horizontal indents.
The utility model that adopts technique scheme to realize has been strengthened the horizontal and vertical hardness of lightgage steel joist, and is sturdy and durable, not yielding, thereby effectively strengthens the effective carrying and the impact resistance of lightgage steel joist.
