Description

Description of the metal cladding for stone stair construction DI_e metal cladding has a pedestal for the stair sole and an upper sa-z; 'Ur die .'reppenstufen.

The base consists of the following parts; 1. Removable pipe changes 2. Extensible tubular struts for the length and width of the stairs 3. E'ne from different large tables of gumrii with linen or e; _nem similar press-oPf 'composed Ceiling according to the roofing slate system, rotating ring eyelets 5.S .-. Corner bolts and binding wire, sow-e a few short iron bars as intermediate beams for the wide steps in the spiral staircase.

The main set includes the following parts: I. Small tube stands which be pushed into the tubular stand of the staircase base II. Struts for the length of the staircase and struts for the steps on which the pull-out step boards known on the market be attached III. Spokes for the support of the step struts IV. Easily combustible Fabric made of rubber, plastic or pressed paper, of which around every small pipe stand a coat is placed and at a height which is the depth of the bottom of the stairs corresponds to V. socket pin (uniform) which is also used everywhere on the base can be.

The rotating ring eyelets are worked out in the shape of a yawl on the upper edge of the coat -for the fixed strut position-.

The lower edge of the jacket has evenly milled grooves all around the socket pins can be pushed through with half of their circumference, so that the rotating ring can no longer slide sideways or downwards.

When assembling the formwork, the pipe stands are in their required Height adjusted. Then a rotating ring is slipped over the stand up to at the height of the first step seen from below.

This also happens on the stand opposite. then The next two pipe stands follow with swivel rings slipped on. now these stands are connected with two longitudinal struts and then the cross struts inserted into these longitudinal struts and in the distance of the respective step width. Then follow the next uprights with their rings, being on the outer one, respectively on the long side of the stairs, a longitudinal strut is used again.

At the beginning of the inner stair angle, four rotating ring loops are over the pipe stand striped with the respective following step height.

Then the four cross struts are inserted into the rotating ring eyelets and on the opposite side in the longest strut.

If the stairs turn another angle, repeat the completed career again.

When going up the stairs from the angle will be in a straight direction the cross struts on both sides hooked into the longitudinal struts until the end.

Now the individual panels for the stair sole ceiling are attached on the cross braces, which are attached to the Cross braces are attached, and that according to the roofing slate system. Well be the small tubular stands of the upper staircase are pushed into the stands of the pedestal. These are now connected with the longitudinal struts and the cross struts, just as with the base of the stairs.

On the long side of the outside staircase, where the steps are very wide Spokes attached to the longitudinal struts, creating the curved rise of the stairs for the step height is compensated by hanging the cross braces on these spokes will.

The pull-out step boards are attached to these struts.

The space at the small pipe stands, which through the stairs sole passes through, is covered with a jacket made of the aforementioned combustible material and after the staircase has been cast it is removed by burning it out, which means that it is dismantled the stands are easy to remove from the stair floor.

The holes created by pulling out the pipe stand Remaining in the bottom of the stairs are used to attach the banister.

When dismantling this cladding, the socket pins, which are located highest on the tubular stands of the staircase base, are first removed, after which this strut with the ceiling panels lying on it are removed from the staircase sole.

The further dismantling takes place in the same career.

Afterwards, this cladding can be used again for a new stair casting be used.

Claims (5)

Claim The novelty of the subject of my invention "metal cladding for stone stairs "is characterized as follows: 1. The metal cladding has extendable tubular stands, which are marked with four lines along their entire harrow are in order to always display the four side angles, while simultaneously in these four lines - at a distance of one centimeter each, along the entire length - the same large holes are drilled for proper adjustment. 2. The metal cladding has drilled eyelets, on which the lower circle of mantle is cut out in the shape of a greyhound is, in which the socket pins to determine -with their half circumference- fit exactly; in addition, the upper circumferential circle has a larger diameter and has four indentations provided, in which the longitudinal and partly also the transverse struts are stored. 3. The Metal cladding has extendable braces, which come out flat at their ends and at the very end are somewhat expanded, causing an unintended slip and hanging up is avoided. The metal cladding has a stair sole ceiling made of rubber with linen or some other flexible pressed material, consisting of various large panels, which are at a distance of five centimeters by two millimeters large holes are provided and the edges are sharpened - for a heel-free Crossing-. 5. The top of the metal cladding has small tubular stands, which are also provided with four longest lines and holes - at a distance of one centimeter. I ask the patent office in Münachen to grant a patent for this subject of my invention (metal cladding for stone staircase construction).
