Description

[0001] The invention relates to an arrangement of scaffolding components for a scaffold, in particular a system scaffold, preferably in a frame scaffold, having the features of the preamble of claim 1. Technological background and state of the art

[0002] Scaffolding is used in construction and industry to enable work in areas that cannot be reached from the ground. Two types of scaffolding can be distinguished: system scaffolding and tubular steel coupler scaffolding. System scaffolding is working and protective scaffolding made of prefabricated components, where some or all of the system dimensions are predetermined by connections or fasteners permanently attached to the components. There are two main types of system scaffolding: modular scaffolding and frame scaffolding. Modular scaffolding, or modular systems in the sense of scaffolding construction, are scaffolds whose vertical day systems consist of scaffolding uprights. Prefabricated, permanent nodes for attaching other scaffolding components are installed at regular intervals (modules). Frame scaffolding is scaffolding made of prefabricated components, whose load-bearing structures consist of vertical and / or horizontal frames.Steel tube coupler scaffolds are scaffolds with length- and area-oriented scaffold layers made of steel tubes, couplers, and other system-independent scaffold components. What all of these scaffolds have in common is that horizontal scaffold components, also known as cross bars and longitudinal ledgers, are attached to vertically arranged scaffold tubes, also called scaffold standards or scaffold posts. Diagonally extending scaffold tubes, also known as diagonal braces, can be attached for safety bracing.

[0003] Scaffold decks can be attached to the horizontal scaffolding components, providing walking and working surfaces. The scaffold decks can be arranged in several tiers, one above the other. The space formed by four vertical scaffolding uprights, four cross beams, and four longitudinal beams is referred to as the scaffold bay.

[0004] Frame scaffolding uses scaffolding frames that are connected to each other by floor sections. Each scaffolding frame comprises two scaffolding uprights that are firmly connected to each other by at least one crossbar. A scaffolding bay consisting of scaffolding frames is usually erected as follows: First, two vertical scaffolding frames are arranged at a horizontal distance from each other. The scaffolding frames are connected at a certain height using scaffolding decks. The arrangement of two scaffolding frames and the scaffolding decks connecting these scaffolding frames is referred to as a scaffolding bay. For safety, one or more railings can be installed between adjacent scaffolding uprights. At a minimum, a first railing is installed at hip or back height, for example at a height of one meter, above a scaffolding deck of a first level.This first guardrail ensures that a person cannot fall from the scaffolding floor. To further improve safety, a second guardrail, also known as a knee rail, can be attached between adjacent scaffolding uprights. This second guardrail is usually installed halfway between the first guardrail and the scaffolding floor, for example, 50 cm above the scaffolding floor. A toeboard can also be installed between adjacent scaffolding uprights to ensure that objects cannot fall from the scaffolding floor, but are held back by the toeboard on the scaffolding floor.

[0005] An arrangement of scaffolding components for a scaffold of the type mentioned above is known from WO 2021 / 194336 A1. This arrangement comprises a railing holder consisting of ten separate components, namely a mounting plate, four cross bolts, two tilt levers, two rotation axes, and a retaining plate. The mounting plate is used to mount the railing holder to a scaffolding standard. The lower retaining plate serves to secure the railing element against its lateral removal from the railing holder in a transverse direction away from the scaffolding standard. The four cylindrical cross bolts, of which the two upper cross bolts are each also referred to as cross-connecting element or safety element, and of which the two lower cross bolts are also referred to as fastening protection, are attached to a first flat side of the mounting plate.All cross bolts extend parallel to one another and perpendicular to the mounting plate in the same direction. The lower retaining plate is attached to the two lower cross bolts of the four cross bolts. The two lower cross bolts are arranged at the same first height and at a first horizontal distance from one another. A rocker arm of the rocker arm is each attached to the two upper cross bolts of the four cross bolts so that it can rotate relative to the associated upper cross bolt by means of a rotation axis of the rotation axes. The two upper cross bolts are arranged at the same second height and at a second horizontal distance from one another that corresponds to the first horizontal distance. Each upper cross bolt is arranged at the same vertical distance from the associated lower cross bolt. The four cross bolts are arranged at imaginary corners of an imaginary, upright rectangle.

[0006] From DE 101 12 369 A1 and the parallel WO 02 / 066765 of the applicant, receiving devices for the detachable connection of up to two railing rods of a scaffolding system of the applicant's legal predecessor are known. The receiving devices are welded to the front vertical scaffolding rods of scaffolding frames. Connecting devices are detachably attached to the rear vertical scaffolding rods of the scaffolding frames. These connecting devices each have one of the receiving devices and one connecting device for detachably connecting the connecting device to the associated vertical scaffolding rod of the respective scaffolding frame. Each receiving device has a movable wedge, which serves to clamp the connecting areas of the railing rods.For this purpose, each railing rod has a downward-facing, flat projection at each of its two mutually facing end areas, which can be inserted from above into the associated receiving device. The geometry of the receiving device is selected such that a flat projection of the respective railing rod can be inserted into the receiving device from two mutually facing sides. Similar receiving devices have been known as mass-produced components for many decades under the designation wedge boxes, inner boxes, or railing boxes for the so-called "Blitz" scaffolding of the applicant and its legal predecessors.These receiving devices are made of sheet iron or flat iron and comprise a profile with a U-shaped cross section, which is formed with two side wall parts that are arranged at a horizontal distance from one another and whose fastening ends are angled and connected to a steel scaffolding tube by welding. The two side wall parts extend away from the scaffolding tube essentially parallel to one another in the same direction. At their outer ends, the side wall parts each merge into a transverse web, which is shaped into the interior of the wedge box in such a way that it also has a U-shaped profile, thus forming a guide channel for the wedge that can be moved relative to it. An arrangement formed from such a wedge box and the scaffolding tube is known, for example, from DE 27 57 189 A or the parallel GB 2 011 008 A.In DE 101 12 369 A1, mentioned at the beginning, a base plate is connected by means of welds or welded to such a wedge box, which is also referred to therein as a receiving device and which is or can be detachably attached to a vertical scaffold tube. An outwardly projecting hammerhead-shaped projection unit is molded onto the base plate. The base plate and the projection unit are designed as a one-piece cast part and form a connection device for detachable, simple connection to the vertical scaffold tube. For this purpose, the vertical scaffold tube has at least one elongated hole whose longitudinal axis extends parallel to the longitudinal axis of the vertical scaffold tube.The hammerhead-shaped projection unit of the receiving device can be inserted through the slotted hole of the vertical scaffold tube and then the wedge box can be releasably attached to the scaffold tube by clamping it to it by turning it 90 degrees.

[0007] Each railing rod has flat projections at both ends, each of which has a fastening hook for detachably connecting the railing rod to a scaffold tube, in particular to a scaffolding post. Such railing rods have also been known as mass-produced parts for many decades, for example, from the aforementioned patents DE 79 16 788 U and DE 101 12 369 A1.

[0008] If a second level of scaffolding is to be constructed starting from the first level of scaffolding, such arrangements of wedge boxes on scaffolding uprights have the disadvantage that a railing formed from such a scaffolding rod for a next higher level can only be mounted on the wedge box from this next higher level, so that this next higher level is not secured by a railing against people falling until the railing has been mounted from this next higher level. If such a railing rod is inserted into a wedge box from above as intended, with a flat projection or suspension hook on its projections or suspension hooks provided at both ends, and is not otherwise supported, then the railing rod becomes wedged between the two side walls of the wedge box due to gravity at an angle of approximately 10 degrees to the horizontal.

[0009] DE 100 10 229 discloses a holding device for attaching at least one railing tube to a tubular post of a scaffold. DE 195 04 038 A discloses a scaffold equipped with tubular posts and single and / or double railings, in particular back railings, and with U-shaped wedge boxes attached to the tubular posts.

[0010] Despite all the associated advantages, the above-mentioned constructions are comparatively complex and expensive to manufacture and construct and have comparatively low stability. Summary of the invention
