A glued timber truss comprising two ends, a first end and a second end, the glued timber truss comprising chords (1,2), a top chord and a bottom chord and ascending and descending diagonals (3,4) therebetween making transverse openings across the truss, each diagonal includes at least one timber bar, the truss may include a vertical or a web panel in its end, the truss comprises a bottom chord joint with one descending diagonal, one ascending diagonal, and a bottom chord routing made for the joint area i.e. said bottom chord routing providing a straight single groove receiving aligned lower extremities of the descending diagonal and the ascending diagonal and having a length corresponding substantially to the sum of the lengths of said extremities and wherein said extremities of the diagonals (3,4) have fingers matching with said bottom chord routing, wherein said fingers of the diagonals (3,4) have been adhesively inserted in the bottom chord routing, wherein said bottom chord routing is at least to about halfway across the chord, wherien the diagonals (3,4) have lower and upper longitudinal edges, and upper and lower extremities, said upper and lower longitudinal edges being substantially straight and parallel to each other, characterized in that the lower extremity of the ascending diagonal is essentially formed by one single straight end cut which makes a tip having an acute angle with the upper edge of this diagonal and is essentially parallel with the bottom chord, and wherein the lower extremity of the descending diagonal - i) is essentially formed by two straight end cuts, a first end cut and a second end cut, the first end cut is at least approximately parallel with the upper edge of the ascending diagonal and the second end cut makes an obtuse angle with the first end cut and is essentially parallel with the bottom chord, and said lower extremity of the descending diagonal has an engagement area with the bottom chord routing which is smaller than the engagement area of the lower extremity of the ascending diagonal with the bottom chord routing, or - ii) has a shape, which is symmetric to the lower extremity of the ascending diagonal, said bottom chord joint being so that stresses will extend from one diagonal bar of the joint to the chord and further from the chord to another diagonal bar without spacer blocks and without a mutual finger or butt joint between the descending and ascending diagonal. - i) is essentially formed by two straight end cuts, a first end cut and a second end cut, the first end cut is at least approximately parallel with the upper edge of the ascending diagonal and the second end cut makes an obtuse angle with the first end cut and is essentially parallel with the bottom chord, and said lower extremity of the descending diagonal has an engagement area with the bottom chord routing which is smaller than the engagement area of the lower extremity of the ascending diagonal with the bottom chord routing, or - ii) has a shape, which is symmetric to the lower extremity of the ascending diagonal, said bottom chord joint being so that stresses will extend from one diagonal bar of the joint to the chord and further from the chord to another diagonal bar without spacer blocks and without a mutual finger or butt joint between the descending and ascending diagonal.
