Abstract:
1. Arrangement comprising: a scaffolding component having a connection head, a vertical scaffolding element having a longitudinal axis and extending in the direction of the longitudinal axis, a projection fastened onto the vertical scaffolding element, the projection extending transversely relative to the longitudinal′ axis of the vertical scaffolding element away from the longitudinal axis, and a wedge for locking the connection head to the projection, wherein the connection head is mounted onto the projection with a releasable connection, wherein the projection has an upper delimitation surface and a lower delimitation surface, which extend on both sides of a horizontal center plane of the projection, wherein the projection has at least one perforation for inserting a wedge through it, which perforation is disposed between an inner projection part, in the transverse direction, of the projection, and an outer projection part, in the transverse direction, of the projection, and extends vertically between the upper and the lower delimitation surface, wherein the connection head has an upper head part having an upper wedge opening, and a lower head part having a lower wedge opening, for the wedge that can be inserted through the wedge openings, wherein the connection head has a contact part that has contact wall parts having contact support surfaces that extend vertically, for contact against corresponding, vertically extending outer surfaces of the vertical scaffolding element, wherein the upper head part has an upper contact support surface of the contact support surfaces for contact against a corresponding upper outer surface of a scaffolding element part of the vertical scaffolding element that extends above the projection, wherein the lower head part has a lower contact support surface of the contact support surfaces for contact against a corresponding lower outer surface of a scaffolding element part of the vertical scaffolding element that extends to below the projection, wherein a slot that is open toward the front toward the contact support surfaces, is disposed between the upper head part and the lower head part, with which slot the connection head is mounted onto the projection, wherein the slot, in a front introduction region, is delimited, toward the top, by horizontal upper slot surfaces of the upper head part, and toward the bottom by horizontal lower slot surfaces of the lower head part, which surfaces extend essentially parallel to one another, on both sides of a horizontal center plane of the slot, wherein the slot is delimited, in the transverse direction, toward the rear, by vertically extending slot surfaces of a slot bottom, wherein a passage for the wedge is configured between the upper wedge opening and the lower wedge opening, which passage extends through the upper head part and through the lower head part, intersecting the slot, and aligns with the perforation of the projection, wherein the wedge is inserted through the passage and through the perforation of the projection, so that the connection head of the scaffolding component is locked into the projection, with shape fit, using the wedge that is in a locking position, wherein the wedge can be moved through the passage toward the top, to unlock the connection head from the projection, at least up to beyond the upper delimitation surface of the projection, so that then, the connection head can be removed from the projection, wherein the upper head part is supported on the upper outer surface of the vertical scaffolding element with the upper contact support surface, and the lower head part is supported on the lower outer surface of the vertical scaffolding element with the lower contact support surface, either already when the wedge is in the locking position or when the wedge is in the locking position and the connection head is braced against the vertical scaffolding element using the wedge, wherein the upper head part sits on the upper delimitation surface of the projection with a support body delimited by an upper slot surface of the slot, in a support position, wherein in the support position, the upper contact support surface extends vertically toward the top, all the way to an upper end that is disposed at a first distance from the horizontal center plane of the slot and at a first distance from the horizontal center plane of the projection, wherein in the support position, the lower contact support surface extends vertically toward the bottom, all the way to a lower end that is disposed at a second distance from the horizontal center plane of the slot and at a second distance from the horizontal center plane of the projection, wherein the outer projection part of the projection has a vertical wedge support surface for the wedge, which surface faces toward the inside and delimits the perforation toward the outside, and extends between the upper delimitation surface and the lower delimitation surface of the projection, parallel to or along or in the direction of a vertical axis, wherein the upper head part has a vertical, upper wedge support surface for the wedge, on an inner side of the passage, in the transverse direction, which surface faces toward the outside in the transverse direction, and extends parallel to the vertical axis, wherein the lower head part has a vertical, lower wedge support surface for the wedge, on an inner side of the passage, in the transverse direction, which surface faces toward the outside in the transverse direction, and extends parallel to the vertical axis, wherein the wedge has a first wedge face edge that has a contact surface that extends at a slant in the direction toward the inside and bottom, at an inclination angle relative to the vertical axis, along an inclined axis, and faces toward the outside, which surface, when the wedge is in the locking position and the connection head is braced against the vertical scaffolding element using the wedge, and/or when the wedge is in the locking position, lies against the vertical wedge support surface of the outer projection part only locally, wherein the wedge has a second wedge face edge that faces toward the inside in the transverse direction, which edge has a vertical contact surface that extends parallel to the vertical axis, which surface corresponds to the vertical upper wedge support surface of the upper head part and to the vertical lower wedge support surface of the lower head part, in such a manner that the vertical contact surface of the wedge can be displaced, lying against not only the vertical upper wedge support surface of the connection head but also the vertical lower wedge support surface of the connection head, relative not only to the vertical upper wedge support surface but also the vertical lower wedge support surface, parallel to or along or in the direction of the vertical axis, wherein the slot, in the direction toward its slot bottom or in the region of its slot bottom or in a rear region of the slot, is structured with a shoulder of the upper head part that extends to below the upper slot surfaces of the slot configured in the introduction region, which shoulder is delimited, toward the bottom, by a horizontal upper shoulder slot surface of the slot, and wherein the shoulder, disposed in the support position above the horizontal upper delimitation surface of the outer projection part of the projection, is supported, with its full area, on the upper delimitation surface of the projection, with its shoulder slot surface that extends parallel to the horizontal upper delimitation surface of the projection, in the support position and at least when the wedge is in the locking position and the connection head is braced against the vertical scaffolding element, using the wedge, or already when the wedge is in the locking position, so that the first distance of the upper end of the upper contact support surface of the upper head part from the horizontal center plane of the projection and the second distance of the lower end of the lower contact support surface of the lower head part from the horizontal center plane of the projection are equal in size.
