摘要

A channel support member (2) for use in a support system (1) for board or plasterboard roofs comprising: - a longitudinally extending base portion (3), - a first leg portion ( 4) extending upwardly along a first longitudinal edge (6) of the base portion (3), - a second leg portion (5) extending in an upward direction along a second longitudinal edge (7) of the base portion (3) facing the first longitudinal edge (6) of the base portion (3), - the first and second leg portions (4, 5) respectively comprising a first and second fastening means (8, 9) provided for application with a corresponding first and second respective openings (10, 11) in a stringer or rail (22) of the support system (1), - the first and second means being separated clamping (8, 9) and each other for a first distance (12) measured along the direction n in width of the channel member (2), - a first and a second part (18, 19) of the first and second leg portions (4, 5) being provided in an upper part, that is to say in a remote part of the base portion (3) of the leg portions (4, 5) and being elastically loaded with respect to each other, - the first and second fastening means (8, 9) being provided in the longitudinal end portion (17) of the channel support member (2) and extending from the first and second leg portions (4, 5) along the longitudinal direction of the channel support member (2) in which the first and second Leg portions (4, 5) are provided to be curved towards each other so that the clamping means (8, 9) can be pushed together and moved through the first and second openings (10, 11) of the stringer ( 22) and such that after releasing the first and second fastening means (8, 9), the first and second fastening means (8, 9) move again separating from each other and can now be applied in the openings (10, 11) of the crossbar (22), characterized in that said first and second parts (18, 19) of the second and first leg portions (4 , 5) extend towards each other from the first and second respective longitudinal edges (6, 7) such that the first and second longitudinal edges (6, 7) are separated from each other by a second distance (13) measured at along the width direction of the channel member (2), the first distance (12) being smaller than the second distance (13) and because the first and second parts (18, 19) extend towards each other forming an angle of between 20 ° - 85 °.
