Description

The invention relates to a construction site staircase, those in a fieubau between those in the production of the shell The cast stair landings or landings are attached so that the interior fittings are rebuilt until the final '"is installed can be made.

In the case of high-rise buildings, especially residential buildings, it is customary to build the stairs into the stairwell at the end. So that the plastering, carpentry, plumbing and electrician work can be carried out beforehand in the apartments on the various floors, so-called building site stairs made of wood are arranged between the landings, which are mostly cast concrete slabs, over which the craftsmen use the floors the lieubaus can enter. "These are .austellentreppen after completion of construction no longer usable, and only deliver waste wood."That's why ^Ti austel- devour

lentreppen accounted for a considerable proportion of the construction costs.

In order to eliminate this disadvantage, the task is now of the present invention seen therein, a building site staircase to create that is repeatedly available / finable and all occurring l'repe designs, in particular the arrangement and the Distances of the stair landings can be adjusted in a modular manner.

According to the invention, the port step is achieved by dai3 two parallel landings between the stair landings Beams are laid in which the individual steps are suspended.

The carrier is preferably supported by formwork carriers which are variable in length and which extend at their lower end support against a stop of a tread supported on the front wall of the lower stair landing. The on the Formwork or wooden beams preferably have horizontal beams U-profile in which mounts in the form of regular intervals are fastened by round steel pieces, bolts or rivets *

The stairs preferably comprise two hinged ones Straps, each of which has a leg that carries the wooden panel with a hook that is attached to the inside of the Holds fasteners attached to the IT profile. The end of the other leg of the hinge band slides behind the bracket or the hook on the previous step and prevents the step from folding up.

The U-beam 3 is also supported against the leg 22. The support of the other parallel U-Tr ^;; gers and the supporting formwork beam or: gl. takes place on the other leg 22 of the other hinge of the step, which is parallel to it. In the course of the further description, only one side of the girder along with the support and the steps are described.

Of course ^: the support for the girders 3 does not need to consist of an extensible girder 4, but of another suitable girder of suitable strength, but on construction sites there are generally sufficient amounts of formwork girders Generally still available from the production of the blankets, so that they can be considered as the most appropriate means of support.

The brackets fixed in the U-profiles can also screw bolts or rivets that are inserted through the holes in the U-profile and screwed on by one Mother or a beaten head.

It is also possible through the U-profile of the carrier 3
