DE19936210A1 - Mould for making multi layer concrete stone slabs, preferably with natural stone surface, assembled from beams placed around existing natural stone slab - Google Patents

Abstract

The mould comprises beams (3, 4), the height of which preferably determines the height of the finished slab, which include a claw on one side, that preferably has one or more clamping screws, so that the beams can be fitted together. The outsides of the beams can be smooth in order to give the slab a smooth surface finish, and/or provided with suitable raised and/or recessed profiles to give the slab a textured surface. An Independent claim is also included for a method for making the slabs using the mould, comprising placing the beams around a natural stone slab, adding concrete to the resulting cavity and allowing the concrete to set.

Description

The invention relates to a method and an apparatus for the production of multi-layer concrete slabs Main patent P 199 32 886.2.

Among the embodiments covered in the main patent is already mentioned a quick release device which the Allows the production of multilayer concrete slabs.

The invention has for its object a method and a device according to the preamble of claims 1 to 4 indicate a reliable and clean manufacture allows for multi-layer concrete slabs; also should maximum economy can be achieved.

This object is achieved by the features of claims 1 to 4 Fulfills.

The following consideration will now deal with the device deal with the manufacture of multilayer concrete slabs, where the visible side is preferably made of natural stone Crust plates exist as this is the most common Use case of the invention will be.  

According to the invention that described in the main patent Crust plate placed on special longitudinal beams. This Crust plate is now with the quick release device enclosed on all sides in such a way that at the same time the enclosure as well as the concrete backfill level is determined. In addition, the device is designed such that with a device covered any plate dimensions can be. This happens in such a way that the individual Elements of the device - preferably four bars -, which are displaceable relative to each other, an adjustment can be made to the crust plate. Claws on respective ends of the individual spars engage in each neighboring spar and form a positive Connection - via clamping screws is an additional one Backup possible.

Another embodiment is that the claws are formed with a toothing, which is in the Anchoring the connection to the neighboring spar automatically, so that additional clamping screws can be omitted.

Through an oblique design of the claws can also Taper of the side walls can be determined by Depressions or elevations on the spars is one Design of the stone outer surfaces and the application a company logo can be realized without additional effort.

The invention is explained in more detail with reference to drawings.

Fig. 1 shows the crust plate ( 1 ), which is enclosed by the spars ( 3 , 4 ). The height of the spars forms the height of the concrete backfill ( 2 ).

Fig. 2 shows the arrangement of the spars ( 3 , 4 , 5 , 6 ,) in plan view. The crust plate ( 1 ) including the concrete backfill ( 2 ) is thus enclosed all around.

Fig. 3 shows a spar with one-sided claw ( 7 ) and additional clamping screw ( 8 ).

Fig. 4 shows a spar with one-sided claw ( 9 ), which is formed obliquely, and additional clamping screw ( 8 ).

Fig. 5 shows a spar with one-sided claw ( 10 ), which has a toothing.

Fig. 6 shows a spar with one-sided claw ( 11 ), which is made of sheet metal for space reasons, and additional clamping screw ( 8 ).

Claims (4)

1. Device for the production of multilayer concrete stone slabs of any kind, but preferably with a natural stone slab surface, characterized by the following features:

• 1.1. There are individual bars ( 3 , 4 , 5 , 6 ), the height of which preferably corresponds to the finished stone height, and a claw ( 7 , 9 , 10 , 11 ) arranged on one side thereof, preferably with one or more clamping screws ( 8 );
• 2. 1.2 the individual spars ( 3 , 4 , 5 , 6 ) are smooth on the outer sides to form flat stone outer sides;
• 3. 1.3 the individual spars ( 3 , 4 , 5 , 6 ) are designed on the outside for the purpose of forming different stone outside structures with any elevations and / or depressions;

2. Device according to one of the preceding claims, characterized by the following features:

• 1. 2.1 the claws ( 7 , 9 , 10 , 11 ...) Are designed such that their recess is preferably matched to the thickness of the bars;
• 2. 2.2 the claws ( 7 , 9 , 10 , 11 ...) Are designed in such a way that their recess is preferably a precise fit to the thickness of the spars and that they additionally have a toothing such that the counterpart is fixed by a self-holding effect ;

3. Device according to one of the preceding claims for the production of multilayer concrete stone slabs of any kind, but preferably with a natural stone slab surface and conical stone outer sides, characterized by the following features:

• 1. 3.1 the claws ( 7 , 9 , 10 , 11 ... ) are designed such that their recess inevitably causes the counterpart to be inclined;

4. Process for the production of multilayer concrete slabs of any kind, but preferably with a natural stone slab surface, characterized by the following features:

• 1. 4.1 the natural stone slab is preferably enclosed on all sides with the device according to one of the preceding claims;
• 2. 4.2 the concrete backfilling is preferably carried out up to the upper edge of the device;
• 3. 4.3 after the concrete has hardened, the device is dismantled;
