DE4000891A1 - Prodn. of decorative wall cladding slabs - involves casting slabs with relief pattern on one face - Google Patents

Abstract

The method is for prodn. of concrete slabs with a pattern formed in relief (6) on one face. The slab is cast in a mould consisting of a rectangular frame with front and rear panels and one open side. The front panel has a negative of the required relief pattern formed on its inner face. The concrete, which is formed from a mixture of sand and cement, is poured into the mould through the open side of the frame. The finished slab is used for the decorative cladding of walls or the plinths of buildings. USE - Wall cladding slabs with decorative patterns.

Description

The invention relates to a device for casting base and wall panels in relief design and other motifs ground sandstone.

Building bases and outer walls are becoming more and more intense Any corrosion damage that occurs is subject to enormous deterioration. The stone decay is only a small part of the natural one Process of disintegration (decay of all preprogrammed by nature Matter) than on pollution with its versatile Factors. Wrong preservation treatments Earlier years the wear process (stone decay) to Part doubled. So far, no manufacturer has been related to either Bleaching or the risk of cracking eliminated. The use of acrylates and silicone rubbers or others Chemicals as a soaking agent to protect the rock does not have only significant gaps, the stone decay continues. Film-forming coatings and protective layers are also more likely served as a means of destroying the stone material. The cancellation of damage to building bases, which in particular Dimensions of natural weathering, frost blasting, carbonic acid have been exposed to reaction, etc. through restoration measures such as removal of the damaged areas and subsequent Mortar layer application due to the necessary reinforcement significant disadvantages.

Compared to these disadvantages, the invention is characterized in that that formwork systems are used which are problem-free Pouring ground sandstone onto building bases and buildings enable wall parts. Through this procedure, one becomes the same permanent surface adhesion guaranteed. It is not difficult to instead of ground sandstone other materials such as B. To use concrete.  

Our sober world lacks beauty for more than ever Detail. The search for technologically advanced people is becoming ever more intensive for the unchangeable authenticity:

With this effort he will find himself in past epochs. For things that have survived through their uniqueness. The formwork system opens up the possibility of making old things affordable and thus feasible to redesign and the continuation of an old one Crafts with new tools more permanent, as with previous ones Methods of performing.

In order to support surface adhesion, the masonry after the damaged areas have been removed, additional ones Anchors, e.g. B. stainless steel screws, which with plastic Dowels were attached, poured.

There is a risk of moisture build-up on applied layers at the connection points, which in turn impair liability can.

Moisture also arises from the ingress of rainwater or the water of the snow melt through the base zone into the wall, whereby it is transported to certain heights by the capillary suction, where it evaporates. At z. B. waterproof plaster (from the top edge Running height) the water seeps into the ground and gets into something greater depth through porous foundations in the wall. The high of occurring soil moisture depends on the groundwater level Pore ratios of the masonry and the possibility of evaporation in the upper area of the wall.

To eliminate these shortcomings or to prevent Moisture arrester in the form of narrow plastic strips in an angle of approx. 45 ° in sufficient number to the existing one Masonry attached. The expressly chosen narrow version does not affect surface adhesion. The drainage of moisture outwards through a plastic T-profile with capillary effect reached. The T-profile is attached in the gap between the individual fields of the formwork system. The gap width can by the execution of the formwork can be determined.

The T-profiles also serve the purpose of sealing the gap widths and act as expansion compensation between the individual fields. Because of the entire system, a longer shelf life and Shielding further environmental damage from all previous ones Procedures are guaranteed.  

Some exemplary embodiments are described below with reference to the figures described the invention.

Fig. 1 shows the isometry of the box formwork including all installation parts.

Fig. 2 shows the box formwork in plan.

Fig. 3 shows the detail of a box formwork in front view and section.

Fig. 4 shows the drainage system in isometric view.

Essentially, the formwork system consists of a box frame ( 1 ) with side closure ( 1 a) and end plate ( 1 b), which is used to hold the relief component ( 5 ).

The sandstone relief ( 6 ) is supported by the plastic dowels ( 2 ) with stainless steel screws ( 2 a) in addition to the surface adhesion, which is inevitably caused by the contents.

The gap between the individual fields serves to compensate for expansion and to accommodate the T-profile ( 3 ), via which the moisture conductors ( 4 ) discharge the capillary suction ( 4 a) to the outside. At the same time, the T-profile ( 3 ) serves to seal the adjacent fields ( 6 ).

The relief forms ( 5 ) consist of different masses and materials. These materials are selected based on the design and impression motifs.

In order to hold the relief shapes ( 5 ) through the vertical arrangement in the end plate ( 1 b), a surface-covering plate ( 7 ) is used in the box frame.

After pouring in the sandstone filling material, the plate ( 7 ) is pulled out upwards.

The filling material that is pressed here presses the relief mold ( 5 ) into the bulges of the end plate ( 1 b). This contact pressure maintains the relief shape and enables the selected impression. This technology avoids unwanted marks from the brackets otherwise required for the relief component. The plate ( 7 ) is provided with resilient spacers ( 8 ) of particularly wide area, which enables the plate ( 7 ) to be pulled out without problems.

Claims (3)

1. Formwork system for building bases and wall coverings made of sandstone relief panels, characterized in that the three-sided box formwork consists of the frame ( 1 and 1 a) and the end plate ( 1 b), the end plate ( 1 b) through recesses for the exception of Relief installation part ( 5 ) is formed and the pouring of the sandstone mortar is possible through the upper frame opening. 2. Formwork system according to claim 1, characterized in that the T-profile ( 3 ) serves as an expansion joint to compensate for expansion, and allows the expansion joint to be sealed between the individual fields and with the moisture collector ( 4 ) the capillary suction ( 4 a) over the T Profile ( 3 ) leads to the outside. 3. Formwork system according to claim 1, characterized in that with the plate ( 7 ) and the inserted resilient spacers ( 8 ), the relief installation part ( 5 ) is held in the vertical and is removable.
