DE20012910U1 - Coding of scaffolding components and the like - Google Patents

Description

Coding of scaffolding components etc.

The invention relates to the permanent marking of scaffolding components, formwork elements, etc. for the purpose of their identification, logistical tracking of their use and safety monitoring.

Scaffolding systems and components of scaffolding systems are subject to high requirements in terms of safety and reliability. Scaffolding systems are therefore subject to building authority approval. All system components of a building authority-approved scaffold must be labeled. Based on this, manageable logistics for deployment and safety monitoring are essential.

The approval regulations require that parts of the scaffolding system that are subject to particularly high loads, such as wedge pockets, wedges for the transom connection, wedge heads for the vertical diagonal connection, etc., must be permanently marked. Such marking is done, for example, by specifying letters, numbers, or the manufacturer's symbol.

The reliable use and operation of scaffolding systems requires that they be constructed from original parts that are subject to controlled production and must also undergo certain maintenance cycles.

This also gives rise to the need to record and code essential scaffolding components in use.

The method of applying the coding must take into account the conditions of a rough construction site, frequent assembly and dismantling, and frequent transport of the scaffolding parts. As a result, damage to the coding or marking must be virtually impossible.

There are various options available for marking movable objects from the current state of the art. Common marking methods include applying labels made of different materials, possibly in conjunction with magnetic strips or barcodes. However, such markings can be damaged relatively easily.

Furthermore, DE 39 22 606 A1 discloses a marking in which certain evaluable characters are applied one-dimensionally, i.e. only on the surface of the front or rear window, by means of laser engraving to protect motor vehicles against theft.

The object of the invention is to enable marking and coding of metal parts that cannot be damaged or destroyed and can be reliably evaluated.

An inventive solution to this problem is specified in claim 1. Further developments of the invention are characterized in the subclaims.

According to the concept of the invention, a specific identifier for marking and coding, for example, scaffolding components and formwork material is lasered into essential metal parts.

This laser processing of the metal parts is carried out in such a way that a two-dimensional evaluation is possible at the removal points, i.e. on the surface &khgr; y and in the depth &zgr; of the processing marks.

By applying the laser coding according to the invention, a logistical overview can be created at any time regarding the whereabouts, age and inspection cycles of the individual system components, for example scaffolding.

For example, a visual inspection is required before any scaffolding is erected.

For further explanation of the invention, reference is made to the claims.-

Claims (5)

1. Coding of scaffolding components and the like, characterized in that a readable and/or electronically evaluable code is introduced into metal parts by means of laser processing. 2. Coding of scaffolding components, characterized in that the markings to be introduced into the metal parts by laser technology are created by material removal and/or material breakthrough, so that a two-dimensional evaluation in the coordinate directions surface x y and depth z is possible. 3. Coding of scaffolding components, characterized in that separate metal elements are marked by laser processing, which, after their marking, are permanently connected to the metal parts. 4. Coding of scaffolding components according to one of claims 1 to 3, characterized in that the laser processing is carried out with programmable laser machines and/or punching devices. 5. Coding of scaffolding components according to one of claims 1 to 4, characterized in that the coding consists, for example, of a hole pattern code.
