Abstract

To produce retaining walls with cast-in-situ concrete cores on cast-in-situ concrete strip footing, for slope stabilisation as a gravity dam with or without a cast-in-situ concrete grout and integrated plant enclosures, as well as for borders and walls, for garden, park and landscape architecture, a concrete block is used which, when lined up, forms the formwork for a cast-in-situ concrete grout due to the corresponding, mirror-image shape at the two ends of the concrete block. The block is formed between these two formwork parts in such a way that the thrust of the slope is diverted according to the principle of the arch via the concrete block to the cast-in-situ concrete cores, which, depending on the static loading, transfer the forces via appropriate reinforcement into a continuous footing, the earth to be held then resting on the strip footing and giving the system its stability.

Description

CONCRETE BLOCK FOR GARDEN, PARK AND LANDSCAPE DESIGN

Description The invention relates to a concrete block for garden, Park and landscape design, especially for retaining walls with in-situ concrete cores on in-situ concrete strip foundation, for embankment fortifications as gravity walls with or without cast-in-place concrete and integrated plant borders as well as for bed borders ur.d Eir, peace.

Retaining walls, embankment fortifications and flower beds have the Task to derive occurring earth pressures in such a way that movements of the earth are avoided will.

It is known that concrete blocks of various kinds to secure embankments Kind of use that fall under the concept of the heavyweight wall. These Embankment stones should counteract the embankment thrust due to their high weight.

Furthermore, there are retaining wall elements in L-shape, where the to be intercepted Soil weighs on the lower leg of the right-angled masonry washer their stability gains.

In the back of the wall washers are steel eyelets for mutual Anchoring available. Round bars are pushed through the eyelets, the eyelets then turned over.

The heavyweight walls made of well-known concrete blocks can only be laid up to very specific slope angles. A vertical retaining wall can only be built up to very low heights because of the slope thrust represents too high a tilting moment.

The L-shaped retaining wall elements form a vertical retaining wall. These elements are made in different sizes to accommodate different retaining wall heights to achieve.

With the corresponding height of the retaining wall, the dead weight of the individual elements is so high that they can only be moved on the spot with a crane.

The invention is based on the object of a single molded concrete block to develop that is equally suitable for a heavyweight wall as it is for a vertical retaining wall and can also be used as a bed border.

Furthermore, the molded block should be held in terms of weight so that it can be moved without mechanical assistance.

It should be easy to line up and also vertically stackable and still the necessary stability after relocating the fastening give.

According to the invention, this object is achieved in that when they are lined up next to one another the formwork for a cast-in-place concrete through the corresponding mirror-image shape is formed at the two ends of the shaped stone and the stone so between them two formwork parts is shaped that the slope thrust according to the principle of Vault is derived over the shaped stone on the in-situ concrete cores, which after static Load on a corresponding reinforcement the forces in a strip foundation forward, whereby the soil to be intercepted then weighs on the strip foundation and gives the system its stability.

The advantages achieved by the invention are that a single Concrete block is just as suitable for a heavyweight wall as it is for one vertical retaining wall and can also be used as flower beds in a socket.

The shaped stone can be without mechanical help due to its relative low weight.

It can be easily lined up and stacked vertically and the reinforced in-situ concrete core gives it a very high level of support and rigidity the wall.

The invention is illustrated in the drawing as follows.

They show: FIG. 1 a possible molded concrete block according to claim 1.

Figure 2 and 3 possible variants of concrete blocks according to claim 1.

Figure 5 shows the plan 1 of a retaining wall, which by joining of concrete blocks of Figure 2 arises. It becomes clear that when they are strung together the concrete blocks the formwork for a cast-in-place concrete is created.

Figure 4 shows the view A-A of Figure 5 Figure 6 shows the section B-B to Figure 5.

FIG. 7 shows a section C-C to FIG. 5, which goes through the concrete formwork and the cast-in-place concrete goes.

The working steps for erecting a retaining wall made of molded concrete blocks according to claim 1 are as follows: A strip foundation is to be produced in which the connecting iron for the reinforcement of the in-situ concrete cores are inserted.

The center distance of the connecting iron is the length of the concrete form stone. The surface of the concrete foundation must be leveled off.

After the concrete has hardened, the reinforcement of the in-situ concrete core (baskets) connected to the connecting iron.

The concrete blocks are then loosely placed in a row on the concrete foundation set.

Above that is the next, then the next but one and each subsequent row Set up vertically and flush, depending on the height of the retaining wall.

Then the cast-in-place concrete begins in the concrete formwork.

After the in-situ concrete core has completely hardened, the retaining wall can be be backfilled.

Figure 9 shows the plan view of a retaining wall with an integrated Plant edging made from molded concrete blocks of Figure 2.

The concrete blocks can also be a mirror image of the axis of the in-situ concrete cores be set up.

FIG. 8 is section D-D for FIG. 9.

Even if the concrete blocks are stacked in mirror image independent stability is guaranteed. The in-situ concrete cores are also with this arrangement all the way to the foundation.

Figure 10: When using additional wooden formwork, different Curves and radii are created in a convex or concave shape.

Depending on the height of the terrain to be intercepted, the reinforcement of the In-situ concrete cores and foundations can be dispensed with.

Figures 11 and 12 show the section and the plan view of a gravity wall which can be relocated according to the state of the art.

In order to give the wall an even greater hold, the concrete formwork an in-situ concrete pouring.

If this is not necessary, the shell bodies are used to accommodate Potting soil.
