Title (EN) CORRUGATED,TOOTHED WEB STRIP FOR CONSTRUCTION ELEMENTS
(FR) AME ONDULEE, DENTEE POUR ELEMENTS DE CONSTRUCTION
Abstract: front page image
(EN)In connection with a corrugated sheet metal strip (30) which is suitable as a web strip in construction elements consisting of an upper and a lower flange (202, 203) taking the form of nailable boards and/or timber bonded together by one or more web strips (204), extending edgeways between the flanges and penetrating the latters with teeth which are mutually spaced on the longitudinal edges of the strip, there are suggested means to ensure a correct predetermined penetration depth of the teeth, independent of the different penetration resistance yielded by either flange. The construction element comprises corrugated sheet metal strips (30) which are provided with penetration stoppers (31) which at a predetermined correct penetration depth of the strip teeth prevent further penetration into the flange (35b). The penetration stoppers (35) can take the form of stationary elements integral with the web strip (30) or consist of separate elements attachable thereto. Further, the stoppers may be constituted by sections or positions of the web strip which during the penetration will have their original shape (32, 33) changed so as to form a stopping foot (35a), the portions then preferably comprising appropriate weakened lines so as to facilitate the folding thereof.
(FR)Une bande de feuille metallique ondulee (30) est utilisable comme ame dans des elements de construction consistant en une semelle superieure et une semelle inferieure (202, 203) ayant la forme de planches qui peuvent etre clouees et/ou de madriers relies par une ou plusieurs ames (204), s"etendant le long des bords entre les semelles et penetrant ces dernieres avec des dents qui sont espacees entre elles sur les bords longitudinaux de la bande metallique; des moyens sont prevus pour assurer une profondeur de penetration predeterminee, correcte des dents, independamment des differences de resistance a la penetration qu"offre chaque semelle. L"element de construction comprend des bandes de feuille metallique ondulee (30) qui sont pourvues de butees de penetration (31) qui, a une profondeur de penetration correcte predeterminee des dents de la bande metallique, empechent ces dernieres de penetrer davantage dans la semelle (35b). Les butees de penetration (35) peuvent avoir la forme d"elements stationnaires faisant partie integrale de l"ame-bande (30) ou consister en elements separes attachables a celle-ci. En outre, les butees peuvent etre constituees par des sections ou des positions de l"ame-bande qui pendant la penetration changeront leur forme d"origine (32, 33) pour former un pied d"arret(35a), ces portions etant pourvues de lignes d"affaiblissement appropriees en facilitant le pliage.
