Title (EN) SPRING FOR SUPPORTING HELICAL BOLTS
(FR) RESSORT DE SOUTIEN DE BARRES HÉLICOÏDALES
(ES) MUELLE DE SOSTENIMIENTO DE PERNOS HELICOIDALES
Abstract:
(EN) The invention relates to a spring for supporting helical bolts with cement grout mixture, the aim of which is to support the helical bolt inside the reinforcing borehole (5), preventing wasting time as a result of installing reinforcement in two phases. Said spring is made from a ferrous material in a single solid cylindrical part measuring 5 millimetres in diameter, which starts with an upper supporting wing (9) having a length of 30 millimetres and forming an angle of between 25 and 40 degrees in relation to the axis of the spring, continuing with a spiral shape of 2.5 turns, forming a left-handed thread and a thread pitch of 12.5 millimetres and the inner diameter of the spiral is 24 millimetres, ending with a lower supporting wing (8) which has a length of 30 millimetres and an angle of between 25 and 40 degrees in relation to the axis of the spring, and both supporting wings (8 and 9) are aligned in the same axis of the bolt (4). The invention also relates to a method for installing the spring for supporting helical bolts with cement grout mixture in the reinforcing borehole (5).

Ledit ressort est fabriqué avec un matériau ferreux en une seule pièce cylindrique massive de 5 millimètres de diamètre, laquelle commence avec une ailette de soutien supérieur (9) de 30 millimètres de longueur et formant un angle de 25 à 40 degrés par rapport à l’axe du ressort, continuant avec une forme de spirale de 2,5 tours, formant un filet gauche et un pas entre filets de 12,5 millimètres, le diamètre interne de la spirale étant de 24 millimètres, et se terminant avec une ailette de soutien inférieur (8) de 30 millimètres de longueur et formant un angle de 25 à 40 degrés par rapport à l’axe du ressort, les deux ailettes de soutien (8 et 9) étant alignées sur le même axe de la barre (4). L'invention concerne également un procédé d'installation du ressort de soutien de barres hélicoïdales avec du laitier de ciment dans le trou de renfort (5).
