METHOD OF MANUFACTURING THE CORRIDORS AND THE FORMAT USED IN THE METHOD

The invention relates to the manufacture of corridors from concrete. The invention can be used, for example, in the manufacture of corridors or floors in yards, roads or public spaces.

It is known to make corridors from concrete slabs. However, this is quite laborious, as the tiles have to be placed on the ground one by one and aligned quite precisely. It is possible to prevent the tiles from moving relative to each other 10 by using suitably shaped tiles (see e.g. CH patent publication 427877). However, for casting technical reasons, it is difficult to manufacture tiles in such a way that their movement in the tiling in all directions is prevented.

15 It has also been proposed to construct the aisles by first placing a tray mold on the base, into which the concrete is then poured. The walls of the formwork trays form movement seams between the tiles. One such method is disclosed, for example, in DE patent publication 655809. It proposes the use of a mold made of, for example, cardboard. However, it has not been possible with the known methods to provide tiling in which the displacement of the tiles with respect to each other is prevented in all directions.

A method for manufacturing concrete walkways according to claim 1 and a mold according to claim 2 for use therein have now been invented. Some preferred embodiments of the invention are set out in the dependent claims.

According to the invention, 30 corridors consisting of separate concrete slabs can be made with little work. An additional advantage is that corridors can be made in which the movement of the tiles with respect to each other is prevented both horizontally and vertically.

An embodiment of the invention is described in detail below. In the drawings of the specification, Fig. 1 shows a casting mold used in the method from above and Fig. 2 the same mold from the front. Figures 3-14 show top views of some tiles 2 88945 made according to the invention and Figures 15 and 16 show some possible walls of the molding in cross section.

The mold according to Figures 1 and 2 consists of compartments 1 separated by partitions placed in the same plane, of which there are 16 pieces arranged in a rectangular 4x4 array.

The longitudinal partitions 2 are parallel. Each partition 2 is folded from the center in the same direction along a horizontal line so that the vertical cross-section of the wall is in the shape of a V-shaped side. The transverse partitions 3 are again each folded in the middle along a vertical line in the same way so that the horizontal cross-section is in the shape of an inverted V-letter.

The mold can be made of any suitable plate-like L5 material, for example steel, plastic or cellulose fiber-based material such as cardboard. It is particularly suitable to use a decaying material.

The dimensions of the mold can be, for example: Length 200 - 1200 mm, width 400 - 1600 mm, height 30 - 200 mm.

.>. Q The molds are placed side by side on the primed horizontal area until the entire area is covered. The edges of the outermost molds are sawn according to the edges of the area, and the edges of the open trays 1 are closed with a separate strip of wall material. Finally, the trays are filled with concrete 25 evenly along the edges. Naturally, the vibration necessary to compact the concrete is taken care of.

If desired, concrete of different colors is poured into different parts of the area to create a decorative effect. In this case, it may be necessary to first harden the casting of the first color so that any concrete of any color that may come on top of it can be easily removed.

When the concrete has hardened, a coating corresponding to the cobblestone tiling is obtained, in which the partitions 2 and 3 of the mold act as movement joints between the concrete slabs. Due to the design of the partitions 35, the displacement of the individual tiles in the transverse and vertical directions is prevented.

The shape of the top surface of the compartment trays can be chosen quite freely. Also, the projections on the walls, which prevent the tiles from moving, can be shaped in many different ways.

Figures 3-14 show some possible tile patterns.

When molds are used in which the outermost trays are open from the side and a separate strip of wall material is placed between adjacent molds 5, no thicker partition wall is formed between the molds. When using rectangular molds, two adjacent sides can be made closed and the other two sides open, eliminating the need for separate strips between the molds.

10 The cross-sectional shape of the partitions preventing movement can also be, for example, curved. Part of the partition can also be completely straight. The height of the walls can be, for example, 30 - 250 mm. In addition, the lower part of the walls may have, for example, a horizontal foot 4 about 40 mm wide (Fig. 16). It prevents the mold from sinking into the 15 substrates. When there is concrete on top of it, it helps keep the mold in place in the plane.

The format of the format may also vary. Most advantageous, of course, is that the mold has side walls which fit snugly against each other. The cross-dimensions of the mold compartment can be 20 e.g. 50 - 250 x 100 - 500 mm. The cross-sectional dimensions of the mold can be, for example, 1200 x 1200 mm or 1200 x 3600 mm.

Fastening members, e.g. grooves and wedges, can be formed on the edges of the molds to fasten the moldings to each other. Also, special elements, e.g. pins or the like, can be used to attach the molds to the ground-25.

It may be advantageous to use flexible, liquefied concrete in the casting. According to one embodiment, the mold is filled with concrete on a special pallet, from which it is then taken to the ground.

In principle, it is also possible to form the mold at the casting station with a special machine, e.g. from wall material blanks.
