Definitions
- the present invention relates to a method for manufacturing of composite stones, one in use upper natural stone slab and a lower base layer made of concrete include, which are intimately connected, in the the natural stone slab with its top facing down placed on a support and with a molding box using an elastic surrounding the natural stone slab Element is sealingly enclosed and in which then poured concrete into the molding box and compacted and finally the molding box separated from the composite stone becomes.
- the invention further relates to a device for performing of such a process.
- EP 0 566 084 B1 describes a method as described in the introduction kind known.
- this known method the form frame from the top of the natural stone slab lowered until it encloses it. Then it will be out the inner wall of the mold frame out gripping organs to the Side surfaces of the natural stone slab pressed to a corresponding Sealing between natural stone slab and molded box to manufacture. These gripping organs are around an air pressure hose. If the molding box is lowered, there is between the Natural stone slab facing side of the hose and the Side surface of the natural stone slab a gap that through the Inflation of the tube is overcome until the Lay the hose against the side surface of the natural stone slab. If concrete is now introduced, the inflated prevents Hose a concrete run past the natural stone slab and forms an appropriate seal.
- the sealing hose provided surrounds the natural stone slab Completely. This way, for an all-round Sealed.
- the present invention is based on the object To create a method and a device with which the composite stones mechanically in a particularly simple manner can be produced.
- the elastic element can be in accordance with the invention Way arranged either on the molding box or on the pad be.
- When the element is placed on the pad is from the end faces of the mold box walls or Mold box webs axially compressed when lowering the mold box. If the elastic element is on the molding box, this is the case in one embodiment on the underside arranged by its walls or webs.
- lowering the Mold box becomes the elastic element by contact with axially compressed the base.
- the base and molding box for simultaneous Production of several composite stones can be trained.
- the molding box is divided by webs that go together with the molded box outer walls several natural stone slabs seal it on the base after lowering.
- the elastic element the entire Surrounds the perimeter of a natural stone slab. So it is in a corresponding manner on molding box webs and molding box walls arranged, for example in the form of a circumferential Solid rubber bar.
- the downward movement of the molding box becomes axial compression of the elastic element by limited an attack.
- the stop is in the path of movement of the molding box arranged.
- a special embodiment of the method according to the invention is characterized in that the downward movement of the molding box takes place in two stages, the molding box moving in a first stage until it comes into contact with the elastic element or until the elastic element on the molding box comes into contact with the base and in a second stage the elastic element is pressed together.
- the downward movement of the molding box takes place in two stages, the molding box moving in a first stage until it comes into contact with the elastic element or until the elastic element on the molding box comes into contact with the base and in a second stage the elastic element is pressed together.
- the molding box in which the elastic element is arranged in a recess on the underside of a molding box wall or a molding box web, so that the elastic element projects downwards relative to the rest of the underside, the molding box is preferably moved so far in the second stage until the rest of its underside also hits the surface. As a result, the elastic element is axially compressed until there is a flat finish on the underside.
- the downward movement of the molding box can be stopped, for example, by means of a limit switch when the section of the underside which is not provided with the elastic element hits the base.
- This device comprises a pad a mold box that can be lowered and raised, a device for laying a natural stone slab on the document, a facility for the introduction of Concrete in the molding box, a device for compacting of the concrete in the molding box and a device for removal of the finished composite stone from the device, the Device on the natural stone slab arranged on the base has surrounding elastic element.
- the Device is characterized in that the molding box as a device for axially compressing the elastic Element is formed.
- the solution is in accordance with the performance the elastic element preferably as the natural stone slab surrounding strip made of elastomeric material, in particular Rubber, trained and has a full cross section. It can either be on the base or on the molding box be arranged yourself.
- the elastic element preferably from a support elastomeric material formed on the base, possibly with the interposition of a drawing plate and at least one cavity for receiving a natural stone slab having. It is essential that the cavity is always slightly larger than the natural stone slab, so that always between the natural stone slab and the cavity boundary Gap remains. This gap makes it easier to insert the Natural stone slab and also equalizes dimensional differences the same.
- the edition made of elastomeric material is also designed that the molding box is full of bars and walls can rest on the pad.
- the support section equally wide between two cavities like the associated molding box web, so that the Lowering the molding box through the entire section Web is axially compressed and radially in on both sides System with the natural stone slabs in the two cavities is pressed.
- the outer edges of the edition can also have the same width as the corresponding walls of the Molded box.
- the exact structure of the base is seen in this embodiment so that there is a suitable one on the base Draw plate (sheet steel) is located on the turn the pad made of the elastomeric material with the cavities is arranged for receiving the natural stone slabs.
- the Natural stone slabs are preferably on the Steel sheet on.
- the elastic element located on the molding box itself is the elastic element preferably as a strip or plate made of elastomer Material on the underside of the walls or webs of the molding box attached, for example glued to it. It understands that the bar or plate has voids or forms exactly the cavities formed by the molding box correspond.
- the sections are made of the elastomeric material, either on the pad or on the molding box are exactly the same width as that corresponding walls or webs of the molding box Composite stones obtained in which the base course is made of concrete is slightly wider than the natural stone slab. This Condition is usually desirable when laying the Composite stones a mutual contact of the natural stone slabs to prevent from neighboring stones. But when the concrete base layer should have the same width as the natural stone slab, the walls or webs of the molding box slightly wider than the corresponding ones Sections of the elastomeric material, i.e. so wide that its borders are essentially with the side edges of the natural stone slabs are aligned.
- Another The embodiment of the invention is the elastic element in a side recess at the bottom of the Wall and the web of the molding box arranged and stands down over the bottom. Now becomes a with such a wall provided molded box lowered, so first pushes the elastic element against the base. Between the base and the rest of the bottom of the molding box wall there is a gap. This space is caused by a further lowering movement of the molding box and thus eliminating the compression of the elastic element, until the entire bottom of the mold box wall is flat and lies against the document. This will make the elastic Element pressed laterally against the natural stone slab.
- the center bar of the molding box can be one or two elastic elements in one or two side recesses the wall or the web.
- the elastic element in a lower bezel so that the bezel bumps against the pad when the molding box is lowered becomes.
- a strip made of elastomeric material with a full cross-section Use expediently again a strip made of elastomeric material with a full cross-section Use.
- the height of the elastic element in relation to the Concerning the height of the natural stone slab, the height of the elastic element may be larger or smaller than that of the Natural stone slab or also match this. If the height is greater, it is achieved that in the compressed State of the elastic element this either is flush with the top of the natural stone slab or still higher than this. With both Felling is prevented from getting concrete in the gap between natural stone slab and elastic element penetrates because of entire gap after compression of the elastic element is filled out.
- the present invention covers all three cases the height dimension of the elastic element in relation to the natural stone slab.
- the device shown in Figure 1 has a base 1, on which a drawing sheet 2 or the like is arranged is. An elastic is located on the drawing plate 2 Element-forming solid rubber sheet 3 with two rectangular ones or square cavities 4 is provided. This Cavities are used to hold natural stone slabs, which inserted with their top down into the cavities 4 become. 1 shows two natural stone slabs 6, which are located in the two cavities 4. Man recognizes that the cavities opposite the natural stone slabs 6 are somewhat oversized, so that one is inserted Gap 5 surrounding natural stone slabs between the edges of the cavities and the natural stone slabs remains.
- the rubber plate forming the elastic element 3 has in the illustration of Figure 1 two outer webs and one middle bridge. The height of these webs and thus the rubber sheet corresponds approximately to the height of the natural stone slab 6. In practice, however, the rubber sheet is preferably slightly lower, as later will be explained later.
- the downward movement of the molding box is shown via a not shown Stop limited.
- the stop is arranged that the molding box is moved down just as far, until the rubber sheet comes into contact with lateral deformation kicked with the natural stone slabs and the desired one Has reached height.
- Figure 3 shows an embodiment of the device which in essentially matched that of Figures 1 and 2.
- the elastic element 3 forming Rubber plate provided on the pad 1
- the Walls 21 and the central web 22 of the molding box 20 are on their undersides with corresponding solid rubber strips 23 Mistake. These strips can, for example, with the undersides of the molding box be glued.
- When lowering the Mold box 20 kick the rubber strips 23 with the top of sheet 2 in contact. This will already open up enclosed the sheet 2 arranged natural stone slabs 6, however, as in the embodiment of Figures 1 and 2 between the natural stone slabs and the rubber strips 23 a gap remains.
- the molding box 20 will now continue Moved downward, the rubber strips 23 are pressed together axially and thereby step radially with the natural stone slabs 6 engages, here the same process as above described plays.
- the rubber strips also have here 23 a slightly lower height than the natural stone slabs, so that when compressed they are lower than these are arranged so that some concrete in the existing Gap can penetrate.
- the process of The placing of concrete is the same as in the embodiment of Figures 1 and 2.
- FIG. 4 shows a detail of a further embodiment, namely the middle web of a molded box 30 in section, with the left side of the web partially lowered Condition and the right side of it in the fully lowered Condition is shown.
- This middle bar is designed so that it is on his has two recesses in the corners at the lower end. In these recesses are two solid rubber strips 32 over one suitable upper bracket 34 and a suitable lower bracket 35 arranged.
- the lower bracket 35 stands as shown in the left half of the web of Figure 4, over the underside 36 of the web. Will the molding box now moved downward, the bracket 35 hits first on the sheet 2. By moving the Molding box, the web moves relative to the holder 35, until its bottom 36 against the top of the sheet 2 bumps. This condition is in the right half of the web shown in Figure 4.
- both tops should be about the same height, so that the gap 33 is completely filled and no concrete can penetrate it.
