DE19940188A1 - Natural stone slab production process, involving lifting slab, filling space under it with concrete and removing frames after setting of filling - Google Patents

Abstract

The slab production process produces a crust of slabs. The natural stone slab is positioned on the surface to be clad with lifting tools (3) so that there is no contact with the ground. The cavity under the individual slabs is filled with concrete, plastic or similar. The adjustment frames are removed when the filling has set.

Description

The invention relates to a method and a mobile lifting and laying device for the production of Natural stone slabs according to main patent P 199 32 886.2.

Among the embodiments covered in the main patent is already mentioned a method and an apparatus which the mobile production of multi-layer concrete slabs enables.

The invention is based, another object Method and device according to the preamble of Claims 1 to 5 specify a reliable and enables clean production of natural stone slabs; In addition, the greatest possible economy should be achieved become.

This object is achieved by the features of claims 1 to 5 Fulfills.

The following consideration will now deal with the device and manufacture of natural stone slabs, which the visible side preferably from regular or irregular natural stone slabs exist as this is the most common application of the invention will be.  

According to the invention that described in the main patent Process as well as device for the production of Modified natural stone slabs so that a problem-free and economical production of wear surfaces and the like is made possible. The natural stone slabs are made to measure in the containers described in the main patent sawn and blasted. Then they are along the surface to be manufactured preferably stored on pallets. The subsurface of the surface to be manufactured becomes appropriate compression deducted with split, optional can still use it for later disassembly of the panels a special water-permeable film can be laid. On laid according to the track width of the device The mobile lifting and laying device travels on rails and takes the natural stone slabs from using a lifting tool the pallet, lifts it up and transports it into into the installation area. At the same time, the bottom of the Natural stone slabs using a special mixing and Dosing device can be provided with an adhesive. Using a laser, height scanner and leveling devices this plate is lowered exactly to the finished level and then remains free in an adjustment frame positioned. The still existing cavity between Bottom edge of natural stone and underground is over Injection nozzles with liquid concrete, plastic or stuffed like that. The device then moves around one plate width further and takes with a new one Lift the next panel off the pallet to repeating the cycle. It should be noted here that a separate adjustment frame is required for each plate - Plate weights of 300 kg are not uncommon. To one exact distance or joint width between the individual Plastic slabs will ensure natural stone slabs as a spacer after each plate with which also removed after dismantling the adjustment frame become.

By appropriate natural stone slab dimensions  - about 1.8 m long and 0.6 m wide, can therefore be rational Routes are relocated.

Another embodiment of the invention consists in that these natural stone slabs in using the lifting device a prepared concrete bed is pushed in, if necessary with the support of high-frequency vibrators. In this respect, the adjustment frame, the filling out of Cavities over injector nozzles can also be largely omitted. Because of necessary expansion joints also plastic strips between the individual Natural stone slabs positioned.

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

Fig. 1 shows the mobile laying device ( 1 ), which runs on rails ( 2 ). The lifting device ( 3 ) transports the plates ( 6 ) into the carriageway area ( 4 ). The plate is moved over the mixing and dosing device ( 8 ). The curb ( 5 ) forms the boundary of the road ( 4 ). Vibrators ( 9 ) are arranged on the top of the lifting device.

Fig. 2 shows the plate arrangement in plan view. The natural stone slabs ( 6 ) in the waiting position and the already installed slabs ( 7 ) in the carriageway. The adjustment frame ( 10 ) fixes the slabs during the concrete hardening. Plastic strips ( 11 ) form the gap between the individual panels.
