Upright construction section

DETAILED DESCRIPTION The present invention comprises a construction section having two upright legs spaced from each other and connected by a bridge.
The section is C-shaped and has inwardly pointing edge flanges extending along the longitudinal edges of the section legs.
The bridge of the section has at least one elastic segment with low transverse spring temper that extends in the longitudinal direction of the section.
The elastic segment is shaped from the plane that is formed by the section bridge and provides a flexible connection to the section legs.
With the upright section as defined by the invention, the desired reduction in the transverse spring temper is obtained in that the section bridge is interrupted by at least one elastic segment extending lengthwise.
The upright section consequently consists of two components that are not rigidly connected with one another, but via the elastic segments.
The two components are movable against each other to a limited extent depending on the elasticity of the elastic segment.
It is therefore possible to build up two-board paneling systems with bending elasticity whose permeability to sound is noticeably reduced versus two-board paneling systems with upright sections as defined by the prior patents described above.
To reduce sound permeability, the side on which the elastic segment is shaped is unimportant.
To connect the sections with brickwork walls, however, it is advantageous if the elastic segment protrudes into the interior of the section in the direction of the section legs.
Of course, the section bridge can be equipped with a plurality of elastic segments extending parallel with each other instead of using a lengthwise extending elastic segment.
The elastic segments are preferably equally shaped.
If there is only one elastic segment, it should be arranged in about the center of the width of the section bridge, and preferably symmetrically in relation to a center line of the section bridge.
With the prior sections described above, the section legs are joined with the bridge with bending elasticity via connection zones designed as closed hairpin-like flexible sections
