Title (EN) MODULE FOR CREATING A SPIRAL STAIRCASE FOR A BUILDING SITE, ASSEMBLY COMPRISING AT LEAST ONE SUCH MODULE AND STAIRCASE FOR A BUILDING SITE COMPRISING AT LEAST ONE SUCH ASSEMBLY
(FR) MODULE POUR RÉALISER UN ESCALIER DE CHANTIER TOURNANT, ENSEMBLE COMPORTANT AU MOINS UN TEL MODULE ET ESCALIER DE CHANTIER COMPORTANT AU MOINS UN TEL ENSEMBLE
Abstract: front page image
(EN)The invention relates in particular to a module (2; 7) for creating a temporary spiral staircase for a building site (1), said module (2; 7) comprising a central post (3) of essentially vertical axis (Z) and two or three steps (20) extending radially, in horizontal planes, from said central post (3) to which the steps (20) are secured by a radially inner end. The module is noteworthy in that said steps (20) are secured to a single string (4) in the form of an essentially parallelepipedal plate which is parallel to the axis (Z) of the central post (3) and secured to the outer edge of the steps (20) and of which the long sides (41) are at least partially inclined with respect to the axis (Z) of the central post (3) and with respect to the horizontal planes of the steps (20), the string (4) having an upper end (43) and a lower end (44), and in that said upper (43) and lower (44) ends each respectively comprise one of two attachment elements (45; 46) of which one is designed to removably attach to a vertical upright (5, 8) and the other, arranged as a hook with a downward-oriented concave portion, is designed to removably attach to a horizontal crosspiece (6) of a scaffolding structure.
(FR)L'invention concerne notamment un module (2; 7) pour réaliser un escalier de chantier (1) provisoire tournant, ledit module (2; 7) comportant un poteau central (3) d'axe (2) sensiblement vertical et deux ou trois marches (20) s'étendant dans des plans horizontaux radialement depuis ledit poteau centra! (3) auquel les marches (20) sont solidarisées par une extrémité radiale interne. Le module est remarquable en ce que lesdites marches (20) sont solidarisées à un unique limon (4) sous la forme d'une plaque sensiblement parallélépipédique parallèle à l'axe (2) du poteau central (3) et solidaire de la tranche des marches (20), et dont les grands côtés (41) sont au moins en partie inclinés sur l'axe (Z) du poteau central (3) et sur les plans horizontaux des marches (20), le limon (4) présentant une extrémité haute (43) et une extrémité basse (44), et en ce que lesdites extrémités haute (43) et basse (44) comportent chacune l'un respectivement de deux éléments de fixation (45; 46), dont l'un est apte à se fixer amoviblement à un montant vertical (5, 8) et l'autre agencé en crochet à concavité tournée vers le bas, est apte à se fixer amoviblement à une traverse horizontale (6) d'une structure d'échafaudage.
