Technological background and state of the art

Scaffolding is used in construction and industry to enable work to be carried out in places that cannot be reached from the ground. Two types of scaffolding can be distinguished in the case of scaffolding, namely system scaffolding and tubular steel coupling scaffolding. System scaffolding is working and protective scaffolding made of prefabricated components, where some or all of the system dimensions are connected by connections or connectors permanently attached to the components.

— means of construction are predetermined. There are two main types of system scaffolding, namely modular scaffolding and frame scaffolding. Modular scaffolding or

Modular systems in the sense of scaffolding are scaffolds whose vertical day systems consist of scaffolding posts. Prefabricated, permanent nodes for fastening other scaffolding components are installed at regular intervals (modules). Frame scaffolds are scaffolds made of prefabricated components whose

30 load-bearing structures consist of vertical and/or horizontal frames. Steel tube coupling scaffolds are scaffolds with length- and area-oriented scaffold layers made of steel tubes, couplings and other system-independent scaffold components. What all of these scaffolds have in common is that vertical Horizontal scaffolding components, also known as cross bars and longitudinal bars, are attached to scaffolding tubes arranged in rows, which are also called scaffolding uprights or scaffolding posts. For safety reasons, diagonally extending scaffolding tubes, also known as diagonals, can be attached for bracing.

Scaffolding decks can be attached to the horizontal scaffolding components to form walking and working surfaces. The scaffolding decks can be arranged in several levels one above the other. The space formed by four vertical scaffolding posts, four cross beams and four longitudinal beams is called the scaffolding bay.

Scaffolding uses scaffolding frames that are connected to one another by floor parts. Each scaffolding frame comprises two scaffolding uprights that are firmly connected to one another by at least one crossbar. A scaffolding bay consisting of scaffolding frames is usually constructed as follows: First, two vertical scaffolding frames are arranged at a horizontal distance from one another. The scaffolding frames are connected at a certain height using scaffolding floors. The arrangement of two scaffolding frames and the scaffolding floors connecting these scaffolding frames is referred to as a scaffolding bay. For safety reasons, a railing or several railings can be installed between the adjacent scaffolding uprights. At least a first railing is installed at hip or back height, for example at a height of one meter, above a scaffolding floor on a first floor. This first railing ensures that a person cannot fall from the scaffolding floor. In addition, to improve safety against people falling, a second railing, also known as a knee rail, can be attached between the adjacent scaffolding uprights. This second railing is usually installed halfway between the first railing and the scaffolding floor, for example 50 cm above the scaffolding floor. A toe board can also be installed between the adjacent scaffolding posts. which ensures that things cannot fall from the scaffold floor but are held back by the toe board on the scaffold floor.

An arrangement of scaffolding components for a scaffold of the type mentioned at the beginning has become known from WO 2021/194336 A1. This arrangement comprises a railing holder, which consists 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 on a scaffolding stand. The lower retaining plate is used to secure the railing element against its lateral removal from the railing holder in a transverse direction away from the scaffolding stand. 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 the mounting plate on a first flat side of the latter. All cross bolts extend parallel to one another perpendicularly away from 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 an equal first height and at a first horizontal distance from one another. A rocker arm of the rocker arm is 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 an equal second height and at a second horizontal distance from one another, which corresponds to the first horizontal distance. Each upper cross bolt is arranged at an equal vertical distance from the associated lower cross bolt. The four cross bolts are arranged at imaginary corner points of an imaginary, upright rectangle.

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 railings are known. bars of a scaffolding system belonging to the applicant's predecessor in title. The receiving devices are welded to the front vertical scaffolding bars of scaffolding frames. Connecting devices are detachably attached to the rear vertical scaffolding bars 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 bar of the respective scaffolding frame. Each receiving device has a movable wedge which is used to clamp the connecting areas of the railing bars. For this purpose, the respective railing bar has a downward-pointing flat projection in its two end areas pointing away from one another, which can be inserted into the associated receiving device from above. The geometry of the receiving device is selected such that a flat projection of the respective railing bar can be inserted into the receiving device from two sides pointing away from one another. Similar mounting devices have been known for many decades as mass-produced components under the name of wedge boxes or inner boxes or railing boxes for the so-called Blitz scaffolding of the applicant and its legal predecessors. These mounting devices consist 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. The side wall parts each merge at their outer ends into a crossbar, which is each formed into the interior of the wedge box in such a way that it also has a U-shaped profile, so that a guide channel is formed 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. In the aforementioned DE 101 12 369 A1, such a wedge box, which is also referred to there as a receiving device and which can be detachably attached to can be fastened or is fastened to a vertical scaffold tube, a base plate is connected by means of weld seams or fastened by welding. An outwardly projecting hammerhead-shaped projection unit is formed on 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, the longitudinal axis of which 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 elongated hole of the vertical scaffold tube and then the wedge box can be detachably fastened to the scaffold tube by clamping it to it by turning it through 90 degrees.

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

If a second floor is to be built starting from a first floor of a scaffold, such arrangements of wedge boxes on scaffolding posts have the disadvantage that a railing made from such a scaffolding rod for a next higher floor can only be mounted on the wedge box from this next higher floor, so that this next higher floor is not secured by a railing against people falling down as long as the railing has not been mounted from this next higher floor. If such a railing rod with a flat projection or hook provided at both ends is inserted into a wedge box from above as intended and is not supported in any other way, then the railing rod becomes jammed. Due to gravity between the two side walls of the wedge box at an angle of about 10 degrees to the horizontal.

Despite all the associated advantages, the above constructions are comparatively complex and expensive to manufacture and construct and have comparatively low stability.
