The invention relates to a mounting device for a Supporting part, in particular for an upright or a receiving ring, to form a fall protection, with a supporting part Use with a receiving opening for the support part as well a safety device to protect people from falling, especially in hall construction, using side by side arranged trapezoidal surfaces formed a ceiling or a roof becomes.

When working above a certain height, it is necessary or expediently the people involved in the work before falling to protect. For this purpose, people are at risk Provide areas with appropriate fall protection, which for example, by ropes stretched between stands or arranged Plates can be realized. Openings, into which people could fall, with appropriate safety nets or the like. are covered. There are also regulations which define permitted crash devices. The workers are particularly involved in the construction of industrial halls often at very high altitudes, which is why the fall arrestors too are required by law. Such industrial halls exist mostly from precast concrete, between which so-called trapezoidal sheets to form the ceiling or roof of the hall to be ordered. The trapezoidal sheets are profiles with a substantially trapezoidal cross-section, which is usually made of metals such as steel, stainless steel or aluminum are made. During the manufacture of the trapezoidal sheets formed ceiling or the roof of the hall must Workers on these trapezoidal sheets perform various activities, such as e.g. Fastening the trapezoidal sheets to the reinforced concrete or sealing the trapezoidal sheets. To secure the construction workers are certain on the outer trapezoidal sheets Spaced from each other and between the upright plates arranged or strings or nets stretched. This will make the Secure people from falling. The uprights are attached usually on the under the trapezoidal sheets lying concrete beams by attaching the trapezoidal sheets to the intended Places are cut open and the uprights on the concrete part be attached. By separating the trapezoidal sheets is the Assembly effort increases and the stability of the overall arrangement also suffers. In addition, the installation of such a fall protection particularly complex and time-consuming.
