A multiple-use joint connector of plastic, sheet metal, wood, etc., particularly for roof structures of greenhouses, smelting plants, and the like. Two sleeves are arranged at an angle to one another for the insertion of rafters therein. These sleeves are connected by connecting elements which together with the sleeves define an opening, the axis of the passage of which is perpendicular to the longitudinal direction of the sleeves. This opening is provided for the ridge beam or board. The sleeves are open at both ends. The openings between the sleeves are formed by the end edges of those side walls of the sleeves which face one another, and extend beyond the width of the sleeves by extensions of flanges arranged on the sleeves. Additional openings which are aligned with one another and have a cross section at least as large as that of the beam which is to be inserted therethrough, are arranged in the side walls of the sleeves and/or of the extensions thereof which bridge the space between the sleeves. |
