Description:
ARRANGEMENT FOR CONSTRUCTING PLAYING COURT

FIELD OF THE INVENTION

The present invention relates to an arrangement for constructing a playing court , the arrangement comprising legs and profile beams on which slabs are mounted for forming the flooring of the playing court . The invention also relates to a playing court which is accomplished according to one or more of the appended claims .

BACKGROUND OF THE INVENTION

The invention therefore relates to the construction of sports fields . Current solutions are accomplished with fixed construction methods , which often require a building permit . These methods often require piling, concrete and/or tillage . I f such a structure must be dismantled later, maj or remediation measures wi ll be required to bring the area to the initial condition . Likewise , rebuilding is usually impossible because at least some of the parts break during dismantling . Dismantling generates a lot of waste .

In cities and other agglomerations , there are often vacant areas where playing courts or terraces would be desired for a limited period, for example 1-4 years , unti l the area i s taken into final construction use . It is then not possible to make fixed structures that require a building permit . Thus , the area is often left without reasonable use until the planned construction is completed . Construction in protected areas is also di f ficult with traditional methods . Many sports suf fer from a lack o f venues . For example , the padel game , which has become particularly popular recently, would need plenty of more fields . However, current construction methods for fields almost invariably require a building permit , which cannot be obtained i f the area is zoned for other uses , even i f the actual construction does not begin until years later . And even i f the area allows construction, obtaining permits will be time consuming .

Uneven or incomplete water drainage is also a problem in many current solutions . Converting and improving existing solutions is demanding and expensive .

The FI utility model 12282 presents a system which is easy to assemble and disassemble . It acts as a lightweight terrace , but the structure is not sturdy enough for use as a playing court .

SUMMARY OF THE INVENTION

The obj ect of the present invention is to provide a novel arrangement for a playing court which does not involve the problems encountered in the known solutions . The arrangement according to the invention is characteri zed in that frame beams are installed between legs and profile beams at a distance from each other over substantially the entire area of the playing court .

In one embodiment of the invention, the structure formed by the frame beams is surrounded by a frame body formed by the beams .

In another embodiment of the invention, F- shaped adapters are arranged at the corners of the frame body, by means of which the beams of the frame body are mounted at the corners over the legs . In yet another embodiment of the invention, the connection between the frame body and the frame beam is accomplished with a T-shaped adapter .

In yet another embodiment of the invention, the profile beams are attached on the frame beams perpendicularly to them .

In yet another embodiment of the invention, the profile beams are attached on the frame beams with a substantially U-shaped adapter .

In yet another embodiment of the invention, the slabs are mounted in place by means of a trus s adapter attached on the profile beams .

In yet another embodiment of the invention, the slabs are mounted in place at intervals of about 5 mm from each other .

In yet another embodiment of the invention, the arrangement can be thermally insulated by installing insulations under the s lab layer in interstices of the profile beams .

In yet another embodiment of the invention, the insulation is provided with grooves for heating or cooling piping .

In yet another embodiment of the invention, a storm- and floodwater basin is constructed under the playing court .

The invention is based on an independent , floating frame structure which can be mounted on very versatile supports . Height di f ferences in the area can be, for example, 0-1000 mm. By modifying the components, it is naturally possible to achieve even greater height differences .

The invention consists of prefabricated steel frame parts which are mounted as a whole entity on height-adjustable stands. The joints are detachable, so that parts of the invention can be disassembled and reassembled in a new location if necessary. Disassembly does not generate waste and the components can be reused. Also, the support on which the playing court was installed will remain in the same condition as it was before construction.

Thanks to the easy installation and disassembling, the invention can be installed in an area where disassembling is required for the winter and re-instal- lation for the following summer. Installation on protected land areas will not cause long-term, visible damage. After removal, the places of the stands must be repaired at most.

In interiors with protected bases (e.g. Malmi Airport hangars) , the invention can be installed in order to protect the original surface and for making the space available for use.

The structure according to the invention can also be installed on top of an old, damaged playing court without the need to dismantle and renovate the entire old court.

The frame structure according to the invention also enables insulation, and freezing piping for artificial ice fields or heating piping for football fields for maintaining defrosting can be installed in the frame structure. In the past, one problem has been finding leaks in the free zing or heating piping . In this case , the courts had to be closed for a long time due to searching and repairing the leaks . Thanks to the floating implementation method of the invention, leakage points can be detected by checking under the frame structure where the leakage is . The problem can be precisely targeted, and repairing is easy after the surface slabs have been opened .

The load-bearing surface of the invention consists , for example , of 20 mm thick slabs , between which gaps of about 5 mm are left , whereby water can escape ef ficiently from the entire area .

The invention is easily adaptable to di f ferent applications . The si ze and intended use as well as the frame structure are defined accordingly . I f an already installed court is wished to be enlargened, the frame body of the area to be enlarged is removed and modi fied to the new dimensions . Additional frame parts are connected to the old ones .

The sturdy frame body beam allows di f ferent types of railings and playing court walls to be integrated into the whole without separate structures .

DETAILED DESCRIPTION OF THE INVENTION

It is essential for the arrangement according to the invention that it is assembled, at least mainly, from finished components. In Figure 1, reference numeral 1 denotes legs, which are preferably height-adjustable and made of, for example, 100% recycled plastic. Legs 1 are installed at intervals of a maximum of 2 meters. The legs 1 may be similar to those shown in the FI utility model 12282. Reference numeral 3 denotes beams of the frame body, which are, for example, 100x200x5 mm in size and made of powder coated steel. They are installed so that their height direction is greater than their width direction. Frame body means a beamwork surrounding the outer edges of the playing court, and it thus consists of beams 3. A T-shaped adapter 2 shown in Fig. 2 is mounted on the extension part of the beams 3, where the gutter 2' thus is intended for the beams 3. The beams 3 are attached to the gutter 2' of the adapter 2, for example with 10 mm bolts and nuts. The beams 3 may have a length of 2-6 m.

To the gutter 2", perpendicular to the gutter 2' , of the adapter 2, is attached a frame beam 4 having a size of, for example, 100x100x5 mm and, for example, of powder coated steel. Thus, a T-shaped adapter is installed at each extension part of the beams 3, wherein also a frame beam 4 is installed to it, although in Fig. 1 no adapter is drawn for the rear frame beam 4. A straight adapter can be used for the straight extension parts of the frame beams, which is thus attached to each of the abutting frame beams 4.

As can be seen further from Fig. 1, profile beams 5 are mounted on the frame beams 4, perpendicularly to them, by means of substantially U-shaped adapters 6. This installation is explained in more detail in connection with Figures 5-7. As can be seen further from Figure 1, the walls

7, railings etc. of the playing court can be mounted on the frame beams 3.

Figure 3 shows the angular structure of the frame beams 3 of the frame body. It uses an F-shaped adapter 8 according to Fig. 3 with gutters 8' for the frame body beams 3 and a gutter 8' ' for the frame beams 4. The fastenings of the beams 3 and the frame beams 4 to the adapter 8 are again made, for example, with 10 mm bolts and nuts. Figure 3 also shows two profile beams 5 to be mounted on the frame beams 4 and their fastening adapters 6.

Figure 5 shows the frame beam 4 and the profile beam 5 to be mounted perpendicularly on it. The fastening takes place in such a way that a substantially U-shaped adapter 6 is attached to the frame beam 4, for example with 8 mm bolts, to which the profile beam 5 is fastened by pressing. The shape of the adapter 6 locks the profile beam 5 in place. Figure 6 shows a profile beam 5, which may be, for example, of 1.5 mm galvanized steel . The installation interval and division of the adapters 6 are made as required in each case .

Figure 8 shows the installation of the slabs 9 on the profile beam 5 . This is done with a truss adapter 10 in the shape according to Fig . 9. The slabs 9 can be , for example , of a ceramic material or stone . They are typically 20 mm thick, but may have other thicknesses as needed . The truss adapter 10 is formed so that a gap of about 5 mm is left between the slabs to al low water to escape from between the slabs . The trus s adapter 10 is made of , for example , 100% recycled plastic and can be attached to the profi le beam 5 , for example by riveting .

When the frame of the playing court is ready with slabs 9 installed, the necessary railings , walls and the final flooring surface intended for use can be installed .

The arrangement according to the invention can also be provided with a defrosting system . This is shown in Figures 10 and 11 . A water-permeable insulating plate 11 is installed under the slabs 9 in interstices of the profile beams 5 . A gap of 5 mm is left at the slab j oints and between the frames to ensure water drainage . The insulating plate 11 can be provided with gutters 12 ( Fig . 11 ) , in which the heat piping 13 of the defrosting system, which is typically of liquid circulating type , is installed . This same application can, of course, also be used for cooling, for example as an ice field freezing solution . In this case , the piping 13 is a cooling piping .

In a possible embodiment of the invention, a storm- and floodwater basin 14 can be built under the playing court ( Figure 12 ) . In thi s case , the basin is made from concrete under the frame and its size is determined project wise. If the assembly is installed at the lowest point of the recess, heavy rainfall can drain over the frame (playing court) and through the slab joints into the basin 14. The basin 14 can also be used in such a way that if the city's stormwater system is overloaded, the rising water can drain through the piping into the basin 14. The water in the basin can be used later, for example for irrigation, or it can be directed to a treatment plant when it has a sufficient cleaning capacity. An empty basin 14 can also serve as a maintenance space, which gives access under the playing court. This makes it possible to maintain artificial ice rinks and heated playing courts from below in the event of any problems. In this case, the surface of the playing court does not need to be opened unnecessarily.

Figure 12 thus shows a storm- and floodwater basin 14, preferably made of concrete. In Fig. 13, steel legs 15 supporting the playing court have been added to this. Frame beams 4 are mounted on the steel legs (Fig. 14) . As shown in Fig. 15, profile beams, perpendicular to the frame beams, are mounted on the frame beams 4, and further, plates 9 are mounted on them as previously described .

Figure 17 shows a finished playing court provided with a storm- and floodwater basin 14.

It will be clear to a person skilled in the art that the invention is not limited to the embodiments described above but can be varied within the scope of the appended claims. Thus, for example, the size, shape, and material of the above parts may differ from those defined above, as necessary. The invention can thus be used for example in terraces and various playing and sports fields such as padel, tennis, football and hockey fields. These are just examples.
