Definitions

  • the invention relates to an arrangement of scaffolding components for a scaffold, in particular a system scaffold, preferably in a frame scaffold, with the features of the preamble of claim 1.
  • 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.
  • 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
  • FIG. 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.
  • 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.
  • 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.

Abstract

L'invention concerne un agencement (15.1) d'éléments d'échafaudage, comprenant un poteau d'échafaudage (17.1) avec un support (18.1) et un élément de garde-corps (19.1). Ce dernier présente une entretoise de garde-corps (21.1) et un crochet de fixation (23.1). Le support (18.1) comporte une partie paroi de retenue (34.1) pour empêcher l'élément de garde-corps (19.1) d'être retiré latéralement du support (18.1) dans une direction s'éloignant du poteau d'échafaudage (17.1). Le support (18.1) comporte un premier élément de liaison transversal (35.1.1) pour soutenir le premier élément de garde-corps (19.1), ainsi qu'un deuxième élément de liaison transversal (35.1.2) pour soutenir un deuxième élément de garde-corps. La partie paroi de retenue (34.1), le premier élément de liaison transversal (35.1.1) et le deuxième élément de liaison transversal (35.1.2) délimitent un premier espace de réception (38.1) dans lequel est reçu le crochet de fixation (23.1) de l'élément de garde-corps (19.1) soutenu sur le premier élément de liaison transversal (35.1.1). Le premier élément de liaison transversal (35.1.1) et le deuxième élément de liaison transversal (35.1.2) sont chacun reliés directement au premier poteau d'échafaudage (17.1) par soudage, de sorte que le premier espace de réception (38.1) soit également délimité par le premier poteau d'échafaudage (17.1). En variante ou en outre, le premier support (18.1) peut être produit à partir d'une pièce unique et/ou formé d'un seul tenant.
