Definitions
- the invention relates to a device for erection a formwork for the underside of the stair case Building stairs, especially one around at least one corner running stairs, with a substructure and a of this to be held in height, forming the formwork surface Formwork covering.
- the present invention is therefore based on the object a device of the type mentioned create an easier and faster shell from Bottom of the stair body on the construction site.
- Formwork covering on the erected substructure with mats to be laid on the formwork surface corresponding to the covering has flexible mat links that are braided cross and are rigidly connected.
- Such mats correspond to the flexible mat members bendable without plastic deformation and in itself twistable. Furthermore, due to the rigid connection the mat links at the crossing points Change the surface shape of the mats so that from a in the initial state rectangular mat a total slightly curved mat can be obtained. To this The mats fit in with the appropriate substructure practically automatically the desired course the bottom of the stair case, especially even on a stair corner where you can easily bend one trimmed mat edge needed.
- the mats do not have to be cut beforehand.
- the mats can be formed by a so-called wave grid be, that is, they can be wavy Wires exist as mat links. Such Mats are commercially available.
- the mats can also strip like material have as mat members, such that the mats a form essentially a closed surface.
- Fig. 1 is a stair body 1 in the building below arranged stairway 2 and one in the next upper Floor arranged stairway 3 emerges. Between the stairs 2 and the stairs 3 runs the stairs at right angles around two corners. In every corner area widen those that form the treads horizontal step surfaces 4 starting from the relevant Inner corner area 5 of the stair body 1 to the outside to the associated Outside corner area 6 out.
- the individual steps are represented by those with solid lines vertical step surfaces 7 separated from each other.
- the stair body 1 is cast from concrete. In the drawing the formwork required for this is still attached.
- the stair body 1 is correspondingly outside Building walls at right angles to each other 8, 9, 10 to which it is cast.
- the underside of such a stair body 1 runs not step-like, but area-wide throughout, whereby a multi-axis curved surface in each corner area results.
- the underside of the stair body 1 points in the Processing, for example, the shape 14 shown in FIG. 6 on. It can be seen that in the processing of the inner corners 5 and especially outgoing from the outer corners 6 Edge areas with a curved course result.
- a corresponding must Formwork on the underside with a formwork covering 15 one of the bottom of the stair case corresponding formwork surface 16 forms.
- the button surface 16 thus also has the one shown in FIG. 6 in the settlement Figure 14 on.
- the formwork covering 15 is of a substructure in the height held.
- This substructure shows in Longitudinal direction of the stairs at a distance from one another, Cross struts running across the stair width 17 on (in Fig. 1, reference numeral 17 is not all Cross struts entered), with their two ends after supported at the bottom by suitable support devices are.
- the cross struts 17 thus span a surface that runs essentially parallel to the formwork surface 16.
- the Cross struts 17 advantageously have a stepless changeable length so that it matches the respective stair width and within the same staircase to each Stair area can be adjusted. In the corner areas of the stairs, the cross struts 17 must be a larger one Bridge the route, since they run diagonally here.
- Embodiment consist of the cross struts 17 for this purpose two strut parts 18 guided telescopically to one another, 19, of which at least the larger diameter one strut part 18 tubular and the other Strut part 19 longitudinally displaceable in the former Strut part 18 is inserted.
- the respective cross strut length can be determined. This can be done, for example, as shown in FIG. 5 take place that in the one strut part 18 in radial Direction of a locking screw to be operated from the outside 20 is screwed in against the inserted Strut part 19 is screwable and clamps it.
- the associated with the locking screw 20 on the strut part 18 Tapped hole can be from a welded threaded nut be formed.
- the stairs are on both sides of fixed building walls could be limited by a detection device for the cross strut length.
- the stair case is on the inside is limited by the formwork elements 11, 12, 13 however at least some of the cross braces in length be ascertainable so that one can cross struts that on the other hand are attached to the building, at the same time as Use formwork holder for the formwork elements 11, 12, 13 can, if with its end facing this at the respective Formwork element to be attached.
- Such longitudinal beams are used above all if there is already one on the relevant side of the building standing building wall is present. Accordingly depending on the local conditions, not only on one, but such longitudinal beams on both sides of the stairs be provided as a support device.
- the cross struts 17 on its end facing the inside of the staircase is not from continuous side members, but each of one separate support member 29 held.
- This support element 29 is arranged on the facing side of the staircase Wall element attached, being in the embodiment these wall elements from the formwork elements 11, 12, 13 are formed, to which the support elements 29 are nailed or can be screwed on.
- the side members 22 - 26 could also be seen on both sides of the stairs from such support members 29 formed support means provide.
- the mounting of the cross struts 17 on the support devices can be done in different ways. Conveniently it is provided that the support devices upstanding support bolts 30 or 31 or the like. exhibit, on which the cross struts 17 are attached.
- cross struts 17 with a tubular shape can so that the support bolts 30 and 31 each through a radially directed hole 32 and 33 in the cross strut to the opposite of the hole, closed trained cross strut wall 34 and 35 inserted or that conversely the cross struts in this Way to be attached to the support bolt so that the Cross struts with the cross strut wall 34 or 35 on the each facing support pin rests.
- the cross struts 17 can be used for fine adjustment of their height with reference to the facing support device in the Height adjustable.
- the support bolts 30 are threaded bolts height adjustable on the respective support device, in the embodiment on the longitudinal beams 22-26, are arranged.
- the cross struts are 17 height adjustable only on these side members 22 - 26 attached while at the opposite end the support elements 29 such a height adjustment is missing.
- the height adjustment can be done very simply so that the threaded bolt forming the respective support bolt 30 above and below the relevant side member 22 - 26 each have a screwed adjusting nut 36 or 37 carries so that the threaded bolt with the desired projection clamped upwards on the relevant side member can be. With loosened adjusting nuts the threaded bolt concerned twists.
- the support bolts 30 are through the side members 22-26 put through.
- the side members in their Plug holes distributed longitudinally in the manner of a row of holes 38 on.
- This substructure and its cross struts 17th serve as a base for the formwork covering 15.
- This has mats 39 made of flexible mat members 40, 41, that cross over each other like braids and are not rigid with each other are connected. A number of such mats 39, which can overlap with their edge areas (see Fig. 2 and 5), so placed on the substructure, that there is a covering corresponding to the form surface 16 results.
- the mats 39 have a rectangular shape. She can easily join due to their flexibility the curvature and curvature of the spanned by the cross struts 17 Adjust area. You can use the cross braces 17 in particular by connecting using a Wire piece or the like. be attached (not shown).
- the mat members 40, 41 form a lattice-like structure, the mat links running parallel to each other 40 the other mat members 41, which are also mutually are parallel, cross at right angles. Since the Mat members 40, 41 at the intersection 42 are not rigid are connected to each other, they can make a relative movement here run towards each other so that the mats in their Level are changeable and especially in one slightly curved shape can be brought (Fig. 4). To this The mats 39 can be used anywhere, including in the Stair corners up to the adjacent wall (building walls 8, 9, 10; Formwork elements 11, 12, 13) are placed. From the mats 39 it is possible to see the one shown in FIG Achieve development form 14.
- the mat members 40, 41 formed by undulating wires, so that there is a so-called wave grid.
- the mat members 40, 41 formed by undulating wires, so that there is a so-called wave grid.
- Each Mat member 40 is alternately above or passed under one of the other mat members 41 or vice versa, so it is one fabric-like structure.
- Mat members 40, 41 not at the intersection 42 are spot welded together. They are at the crossing points only by the through the tissue-like The resulting elastic force against each other pressed.
- the mats 39 are stable or the distance between the Cross struts 17 is chosen so small that the mats 39th do not sag downwards between the cross struts 17.
- Form the mats 39 as in the embodiment openwork area are shown on the mat Mat structures forming the formwork surface 16, closed Surface elements 43 made of flexible material laid across the board.
- the surface elements 43 thus form a closed surface, on which then the stair body 1 resulting concrete is poured.
- These surface elements 43 can be rubber mat-like or made of film-like Plastic. Also, for example, polystyrene panels or the like. are possible.
- These surface elements can either the development form according to FIG. 6 be cut accordingly (dash-dotted lines in FIG. 6) Dividing lines between such cutting sections indicated), or it is a Number of surface elements with their border areas can be placed one on top of the other so that their individual shape no such great value needs to be placed anymore.
- the surface elements 43 thus form the formwork skin, so to speak.
- Mats made of tape-like material also strip as mat links exist, in such a way that the mats one in form an essentially closed surface.
- Such braids can be found for example in chip baskets etc. In one such cases could also be applied to the surface elements 43 do without and use the mats themselves as formlining.
