Detailed description of the invention
Better understand the present invention for the ease of those skilled in the art, be described in further details below in conjunction with the drawings and specific embodiments to the present invention, following is only exemplary do not limit protection scope of the present invention.
Embodiment 1
With reference to accompanying drawing 1 and Fig. 2, a kind of steel bar girder, comprise wind up muscle 3, two lower edge muscle 2 and the abdomen muscle 1 that welds with the muscle 3 that winds up, abdomen muscle 1 is two groups of continuous wave shape wave reinforcing bars; The peak of the single ripple of two groups of continuous wave shape wave reinforcing bars is all welded as a whole with the muscle 3 that winds up, the minimum point of the single ripple of two groups of continuous wave shape wave reinforcing bars is symmetricly set on muscle 3 both sides of winding up, and the minimum point of the single ripple of two groups of continuous wave shape wave reinforcing bars is welded as a whole with lower edge muscle 2 respectively.
