The! Price increase refers to sand play boxes, "consisting of a base plate with drainage pipe and side walls made of precast reinforced concrete elements that sit on the base plate and are joined together to form a frame.

The well-known sand play boxes are made of wood. They only have a limited lifespan, because the wood, even if it is provided with protective impregnation, is subject to constant impact the weather, as well as the moisture contained in the soil and the soil bacteria in the long term do not resist kr-nn »A paintwork only offers temporary protection because it is abrasive of the sand and the inevitable mechanical stress caused by the playing

Children will soon be destroyed again «Furthermore, the mechanical resistance of a wooden one Game box is limited, so that repairs are required from time to time with frequent use »Furthermore there is a risk of children playing in wooden sand play boxes of tearing splinters or themselves to injure on protruding nails, a sandpit Made of wood therefore requires constant maintenance because of the high level of wear and tear in order to be operationally safe.

The innovation is based on the technical task a maintenance-free sandpit with an unlimited lifespan that is not tied to a fixed location? at simultaneous elimination of any risk of injury to create for the children using the sand play box.

This object is achieved in that precast reinforced concrete parts are provided for the side walls are assembled to form a frame. This frame can have the shape of a rectangle, but it can also round or any other shape. This reinforced concrete frame sits on top of a stone block Base plate in which there is a joint that divides the base plate into two parts. Both parts of the The base plate is slightly inclined to the joint «For rectangular

Sand play boxes, the joint runs parallel to a side wall, preferably the narrow side. Under the A drainage pipe is attached to the joint, through which the rainwater that collects in the joint can drain away can. This drainage pipe, which is attached under the joint, is an important part of the sand play box according to the innovation, as this ensures that there is never water in the play box filled with sand can stow. The previously known sand play boxes do not have such a drainage pipe »

The surfaces of the reinforced concrete prefabricated parts provided for the side walls of the sand play box can be flat being. "But they are preferably corrugated on the inward-facing side and with one parallel to the provided with a central bead running along the longitudinal edge. Due to this wave shape the inner surface will be considerable Saving quantities of reinforced concrete. The individual parts are thereby considerably lighter, which is important for transport and Assembly is important. The central bead ensures the highest degree of static stability of the sand play box and also allows easy control of the amount of sand in it.

The precast reinforced concrete parts provided for the side walls of the sand play box offer the advantage that

the box is easy to clean and keep clean. It does not require any maintenance, as the concrete parts neither through atmospheric nor are attacked by microbial influences and also no wear and tear from constant Subject to use. Another advantage of the price increase is that the sandpit is not is tied to a fixed location, but can be set up again at another location at any time. One Another way to use the sandbox that is no longer needed for playing is to use it for example to use as a flower box. This makes it very economical to use and provides one represent real technical progress.

As can be seen from FIG. 1, the base plate of the sand play box consists of stone slabs 2 "through
an eye 3 running in the base plate parallel to one side of the frame formed by precast reinforced concrete parts 4 and 5, the base plate is divided into two parts, each of which has a slight inclination to
Have joint 3. A drainage pipe β (Figure 2) for draining off water is attached under joint 3 =
On the outer stone slabs 2 of the base plate there are four rectangular reinforced concrete prefabricated parts 4 and 5j that are built together and form the base. Two parallel
Sides of the R; frame are formed by two precast reinforced concrete parts. The other sides of the frame, which are at right angles to these, are formed by precast reinforced concrete parts 5. The precast reinforced concrete elements 4 and

differ from each other only at the ends 7, which the corner connections in the composition of the Manufacture reinforced concrete prefabricated parts for the frame »Fach dem When assembling the frame, all four inner and outer surfaces have the same appearance o The precast reinforced concrete parts 4 and 5 have a step 8 at their upper end towards the outer edge, into the stone slabs 9 can be inserted.

FIG. 2 clearly shows that the base plates 2 are inclined slightly downwards towards the joint 3.

The line 13 13 represents the horizontal plane that

forms acute angles with the surface of the floor slabs «

The side of the precast reinforced concrete parts 4 and 5 facing the inside of the box is corrugated, in the form of a bead 14 and two trough-like channels 11, all of which run horizontally. The precast reinforced concrete parts are located with their underside 12 on the outer floor slabs 2. The bead 14 is at the same time a marking for the filling level of the sand 15 »

A precast reinforced concrete part 4? like it was before assembling of the sand play box is present, is shown by Figures 3, 4 and 5 shown. Figure 3 shows the inside of this precast reinforced concrete part from the front, Figure 4 the plan and FIG. 5 is a profile view. The precast reinforced concrete part 4

has an outwardly v / ironing step 8 with a lower height after assembly, which is used to accommodate the Seat plate 9 is used. At the two ends of the prefabricated part, the gradation is extended »to this recess 16 when assembling the sand play box, the protruding nozzle 19 of the precast reinforced concrete part 5 is pushed on, in order to connect the two prefabricated parts 4 and 5 to one another at right angles, as can be further recognized from FIG parallel to the base 12 an outwardly curved one middle bulge 14 "The apex of the middle bulge is through Line 17-17 reproduced. Above and below the central bead 14, one trough-shaped each runs parallel to it inwardly curved gutter 11 »The direction of these gutters and their maximum indentations are indicated by the lines 18-18 indicated. The grooves 11 and the central bead end in an undulating profile of the perpendicular runs below the recess 16. The profile is like this shaped that the corresponding iiittelwulst 14 and the channels 11 of the precast reinforced concrete part 5 during assembly fit exactly into the frame. This ensures that the central bead in the assembled Sendspielkasten and grooves 11 at the same height around the inside of the frame

The precast reinforced concrete part 5 is shown in FIGS. 6, 7 and 8 shown. Figure 6 shows the inside of this

Precast reinforced concrete part from the front, FIG. 7 the plan view and FIG. 8 a profile view. The reinforced-concrete prefabricated part 5 has, as well as the finished part 4 shown in the Figures 3 _S 4 and 5, an equally large gradation 8 "whose apex along the line 17 --- 17 at the outer edge, a luittelwulst 14, and further comprising two trough-like channels 11, whose mrximal indentations run along the line 18 -> 18.

The precast reinforced concrete part 5 differs from the reinforced concrete part 4 only in that it has a protruding lens 19 at each of its two ends. Furthermore, the bead 14 and channels 11 end so that the narrow sides of the prefabricated part 5 form a smooth surface. Drdurch the two prefabricated reinforced concrete parts can 4 and 5 are assembled at right angles "The channels 11 and the bead 14 of the reinforced-concrete prefabricated part 5 genpu match with those of the steel concrete component 4 together _s when the projecting Na.se 19 is pushed the finished part 5 to the recess 16 of the finished part 4 .

Except for those in FIGS. 3 to 5 and 6 to 8 There are also other precast reinforced concrete elements described Embodiments. The ends of the precast reinforced concrete can have any shape. The only requirement is that the precast reinforced concrete parts are stable and Can be put together seamlessly.

The markings for the amount of sand in the box can be represented by grooves in other embodiments being. The central bead can also be of any suitable shape.

The precast reinforced concrete parts are made in a known manner from cement mixes and steel mesh inserts. Synthetic resins can also be added to the concrete mixes. As a material for the manufacture of sand play boxes According to the innovation, plastics or plastics reinforced with inserts can also be used.
