<I> Floor structure.
The floor 1 is made of concrete, wooden or the like, and can be used as a floor for various ball games, concert halls, or exhibition halls when no artificial turf is laid.
If artificial turf 7 is laid on the floor surface 1, it can be used as a stadium for soccer, American football, and the like.
[0008]
<B> Air supply port.
A plurality of grooves 2 are formed on the floor surface 1.
The upper part of the groove 2 is covered with a cover 3 that can be attached and detached.
When covered with the lid 3, the upper surface of the lid 3 and the floor surface 1 form the same plane.
The lid 3 is an independent plate, and an air supply port 4 is interposed between one lid 3 and the adjacent lid 3.
[0009]
<C> Air supply path.
In addition to the method of configuring the interval between the adjacent lids 3 and the lids 3 as the air supply ports 4, the grooves 2 can be configured as the air supply passages without using the lids 3 in the grooves 2.
In this case, if the narrow groove 2 is formed, the flatness of the artificial turf 7 laid thereon is not affected, and even if the artificial turf 7 is removed, the use of the floor surface 11 is not hindered. .
Thus, the object of the present invention can be achieved even if the air supply section is a point-like supply port 4 or a linear supply path.
[0010]
<D> Air supply structure.
One end of a pipe for supplying air is opened in a part of the groove 2.
The supplied air is manufactured by an external blower or a compressor, and air having a pressure not exceeding the weight per unit area of the artificial turf can be supplied into the groove 2 through the supply pipe.
[0011]
<E> Storage device for artificial turf 7.
A basement is provided at the end of the floor 1, and a winding drum 6 for the artificial turf 7 is installed in this basement. The artificial turf 7 developed and laid on the floor surface 1 by the rotation of the take-up drum 6 can be taken up and collected.
[0012]
<F> A drawer 8 for the artificial turf 7.
A drawer device 8 for the artificial turf 7 is provided in the basement at the other end of the floor surface 1.
This is a drum that winds up the rope 9.
A frame is attached to one edge of the artificial turf 7 in a direction perpendicular to the pulling direction. The artificial turf 7 can be pulled out by attaching the rope 9 to the frame and winding the rope 9.
[0013]
<G> Intervening support.
A large number of independent supports 10 are interposed between the floor surface 1 and the artificial turf 7.
The support 10 is a protrusion having a hemispherical shape, a prismatic shape or the like.
By providing a large number of protrusions as the support 10, a continuous air passage 11 can be formed between the adjacent supports 10.
Therefore, if air is supplied between the supports 10, the air spreads over a wide range through the continuous air passage 11 and gives an upward pressure to the artificial turf 7.
[0014]
<H> An example of an air passage (when provided on an artificial turf).
The upper surface of the artificial turf 7 has a structure in which synthetic resin turf is mounted on a base sheet.
On the other hand, a large number of independent supports 10 are formed on the lower surface of the artificial turf 7.
The support 10 is formed in a hemisphere like a teacup. Then, the continuous air path 11 can be formed between the teacup-like support bodies 10 group.
[0015]
<R> Another example of air passage (when provided on the floor).
A large number of rectangular parallelepipeds, hemispheres, and the like can be arranged on the floor surface 1 to form the support 10.
By arranging a large number of rectangular parallelepipeds, the air passages 11 can be formed between the rectangular parallelepiped groups in a grid pattern.
[0016]
<Nu> Laying method.
The following method for laying the artificial turf 7 will be described.
The artificial turf 7 is wound around a take-up drum 6 and the concrete or wooden floor 1 is exposed.
When laying the artificial turf 7, a rope 9 is attached to the edge of the artificial turf 7 and the rope 9 is wound around the drum at the other end of the floor.
Then, the artificial turf 7 can be pulled out on the floor surface 1 over the entire surface.
[0017]
<Le> Air supply.
At this time, air is supplied from the air supply port 4 of the floor surface 1.
Air is supplied to an air passage 11 formed continuously between the supports 10. Accordingly, an upward force can be applied to the artificial turf 7 from the bottom over the entire surface.
The pressure of the supplied air is controlled within a range not exceeding the weight per unit area of the artificial turf 7, for example.
Then, the artificial turf 7 can be maintained in a state where the artificial turf 7 is not separated from the floor surface 1 and a load is not applied to the support 10.
Thus, if it is pulled out in the horizontal direction with a small frictional resistance, the artificial turf 7 can be easily developed.
[0018]
[Effect of the present invention]
Since the artificial grass laying structure of the present invention is as described above, the following effects can be obtained.
<B> A continuous air passage 11 is formed between the floor surface 1 and the lower surface of the artificial turf 7, and the air supplied to the air passage 11 gives an upward force to the artificial turf 7. is there. Therefore, the artificial turf 7 can support the entire weight without leaving the floor surface 1 while the support 10 is in slight contact with the floor surface 1.
Therefore, the air supply position does not concentrate at a certain position to form an air reservoir. For this reason, it is possible to easily and orderly lay without the labor and time required to remove the air pocket or to stretch the wrinkles.
<B> Although the artificial turf 7 is not separated from the floor surface 1, the entire weight is supported by air pressure, so that the artificial turf 7 can be moved lightly with a slight force in the horizontal direction.
Therefore, both the unwinding and winding operations can be performed in a short time with a simple device, which is extremely economical.
<C> Since the artificial turf is not lifted, it can be operated by supplying a small amount of air. Therefore, a device for supplying air may be as simple as a blower and is economical.
