Description

Stairs Stairs are already known which consist of self-supporting There are block steps, the tread surface with special clay plates if necessary or covered with linoleum. This remains between the individual block levels In the inner corner of the step a joint in which dirt settles or in which the mopping water penetrates when cleaning the stairs. Another disadvantage of such Stairs consists of block steps until the new building is completed manufactured stairs must be protected by a wooden cover, otherwise when transporting the building materials, the steps, especially their front edges, are light to be damaged.

Furthermore, stairs are known in which angular steps with upwards are laid on a concrete cap at an open angle. Such trained stairs show the disadvantage that before placing the angle plates an inclined slope Concrete cap made and stamped or placed on these step triangles must be, which requires great costs and a relatively long time.

Another disadvantage of these stairs is that the Manufacture of the concrete caps, necessary supports of the formwork for the material transport and the other work in the new building is a hindrance. After all, that caused the Production of the concrete caps, the placement or stamping of the step triangles and the embarrassment. The angle plates take a relatively large amount of work and time and allows you to enter the stairs only after the complete completion of the Staircase, which hinders and significantly delays all work in the new building.

The invention relates to a staircase made of block steps with a covering which these disadvantages' are avoided. The new thing is that on the block steps Angle plates are laid with an angle that is open at the top. Through this training the stairs, in which instead of the concrete caps with step triangles as a substructure for angle plates self-supporting, clamped on one side or resting on both sides or clamped, well-known triangular solid or hollow steps are used, which are installed immediately when the stairwell walls are being built up and are shorter Time are put together, once the advantage is achieved that the stairs are instant Can be used after assembling the block steps before being used with angle plates is. Furthermore, there are any supporting pillars that impair freedom of movement in the new building and a cladding of the stairs in failure. Finally, through the during the construction time z. B. damage caused by the transport of building materials the block steps had no adverse effect on the exterior of the finished staircase, because that is to accommodate the step support plates to be laid only after completion of the building required mortar bed and above all the angle plates themselves all damage cover up.

The drawing illustrates two embodiments of the new Stairway.

Fig. I shows a part of the staircase in side view. The self-supporting Steps i are connected to the step support plate 3 by a mortar joint or mortar bed 2.

Fig.2 is the side view of a staircase part, its cantilever. _Step blocks are provided with cheeks g. - Fig. 3 is the front view of the in FIG Fig. 2 violated part of the staircase.

The steps are made of iron-reinforced concrete. If necessary, you can the heads of the cantilevered steps when they are made or later be clad and processed with better material. The bottom of the free load-bearing steps can be plastered or made in another design.
