Steel single-lip channel bar

Abstract

The present invention has an object to enhance drainage of a rack in a case where a single-lip channel steel bar is used as a transverse beam or/and a longitudinal beam and a flat-plate-like solar panel module or the like is placed on the transverse beam. The single-lip channel steel bar of the present invention, which serves as a transverse beam and a longitudinal beam, includes a second side plate formed on one side portion of a channel steel bar body. The second side plate is formed only of a flat plate formed at a right angle or a non-right angle with respect to a back plate.

         6 . A single-lip channel steel bar according to  claim 2 ,
 wherein the transverse beam according to  claim 2  comprises the second side plate extending in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction of the back plate, and   wherein, in order to incline the second side plate downward, the transverse beam is provided, through the intermediation of an inclined member having a wedge shape, on the longitudinal beam disposed in the horizontal posture.   
     
     
         7 . A single-lip channel steel bar according to  claim 2   wherein the longitudinal beam according to  claim 2  comprises the second side plate extending in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction of the back plate,   wherein the longitudinal beam is provided on a base member through the intermediation of an inclined member having a wedge shape,   wherein the transverse beam according to  claim 2  comprises the second side plate extending in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction of the back plate, and   wherein the transverse beam is provided on the longitudinal beam through the intermediation of the inclined member.   
     
     
         8 . A single-lip channel steel bar according to  claim 3 , wherein the transverse beam comprises the single-lip channel steel bar according to  claim 3 , and
 wherein the transverse beam is disposed on the longitudinal beam so as to be orthogonal to a longitudinal direction of the longitudinal beam, and a solar panel module having a plate-like shape is provided on the transverse beam, thereby disposing the longitudinal beam, the transverse beam, and the solar panel module ( 1 ) in a horizontal posture or an inclined posture.   
     
     
         9 . A single-lip channel steel bar according to  claim 3 ,
 wherein the transverse beam comprises the single-lip channel steel bar according to  claim 3  comprising the second side plate that is formed of the right-angled plate extending in the right-angled direction orthogonal to the plate height direction of the back plate, and   wherein the transverse beam is provided on the longitudinal beam that is disposed in the inclined posture.
