Gable roof truss component and roof truss with same

The utility model provides a gable roof truss component and a roof truss with the same, and relates to the technical field of building engineering. The technical problems that an existing roof truss is large in height, and the indoor headroom is small are solved. The gable roof truss component comprises two upper chords, two lower chords and ground supporting pieces. The top ends of the upper chords are connected to form a gable girder with the top tip upwards, and the two lower chords are connected in a cross mode to form an X-shaped supporting girder. Two top ends of the X-shaped supporting girder are respectively connected with the upper chord bodies of the two upper chords, and two bottom ends of the X-shaped supporting girder are respectively connected with the bottom ends of the two upper chords. The top tip of the gable girder is connected with the cross point portion of the X-shaped supporting girder through a vertical middle web rod, and a plurality of side web rods are arranged on the two sides of the middle web rod. One end of each side web rod is connected with the upper chords, and the other end of each side web rod is connected with the lower chords. The two ends of the gable girder are respectively arranged on the supporting pieces. By means of the gable roof truss component and the roof truss with the same, large span can be achieved, the own height is small, and the indoor headroom is large.
