Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heating floor structure, particularly to a heating floor structure suitable for gymnasiums, play rooms and the like.

[0002]

[Prior art]

 On floors of exercise facilities such as gymnasiums and play rooms, a plurality of floors that define the floor surface are supported by a plurality of joists. The flooring is elastically deformable between the joists supporting the flooring, and the impact of a person who exercises, plays a game, or plays at the time of contact with the ground is absorbed and relaxed by the elastic deformation of the flooring.

[0003]

[Problems to be solved by the device]

 By the way, the exercise facility may be used, for example, as an auditorium or a theater in addition to its original use. Considering the special use of the exercise facility, especially in winter, it is desirable that the exercise facility is equipped with heating equipment. Floor heating is one form of heating. Since floor heating is installed under the floor, it is possible to use the space on the floor necessary for exercise, competition, and play. In this respect, floor heating is suitable as a heating system for exercise facilities. However, there is a fear that the flooring will warp when the flooring, which is the floorboard, is heated. Therefore, there is no example of floor heating being applied to an exercise facility that uses the flooring as the floorboard. An object of the present invention is to provide a heating floor structure that does not cause the flooring that defines the floor surface to warp.

[0004]

[Means for Solving the Problems]

 A heating floor structure according to the present invention covers a base floor, a plurality of joists arranged on the base floor, a plurality of floorings having a low water content fixed to the joists, and front, side and back surfaces of the flooring. An impermeable coating and a conduit for heating fluid disposed between the substrate floor and the flooring. The water content of the flooring is preferably set to 5.8 to 6.2%. In addition, a groove is provided in the fore edge of the flooring, and the fixing member is fixed to the joist and extends along the joist through a fixing member having a part received in the groove of the fore edge of the flooring facing each other. The flooring can be fixed to the joist.

[0005]

[Function and effect of device]

 According to the present invention, since a flooring having a low water content is used and the flooring is covered with a water impermeable coating, the amount of water vaporized from the flooring due to heating is small, and the air generated by the flooring is small. There is no absorption of moisture inside. Therefore, the fluctuation of the water content of the flooring can be minimized, and by this, it is possible to realize floor heating in which the flooring hardly expands or contracts, that is, warps.

In the flooring having the water content set to 5.8 to 6.2%, the water content of the flooring when heating the flooring for floor heating hardly changes. Further, if the floorings are fixed to the joists via the fixing members, the warping of the flooring can be suppressed more completely.

【Example】

 Referring to FIG. 1, a floor structure of the present invention applied to an exercise facility such as a gymnasium, a play room, etc. is generally indicated by reference numeral 10. Reference numeral 12 indicates a skirting board.

As shown in FIGS. 2 and 3, the heating floor structure 10 includes a base floor 14 such as a concrete floor slab, and a plurality of joists 16 arranged on the base floor 14 at intervals. A plurality of flooring 20 having a low water content fixed on the joist 16 through a fixing member 18 arranged on the joist 16 and extending orthogonally to the joist 16 and a water impermeable material covering the surfaces, side surfaces and bottom surface of the plurality of floorings 20. A permeable coating 22 and a conduit 24 disposed between the subfloor 12 and the floor 20 for flowing a heated fluid.

Each of the joists 16 shown is made of channel steel that opens into the floor 12, and is partially cut away to define a meandering transverse path of the conduit 24. The fixing member 18 of the flooring 20 made of a steel material is fixed to the joist 16 via a plurality of screws 26. Each fixing member 18 is in contact with the joist 16 and allows a plurality of screws 26 to pass therethrough, and a base 28 that allows an L-shaped cross-sectional shape, and a T-shaped or L-shaped cross section that is continuous with the base 28 and cooperates with the base And a flange portion 30 having a surface shape. The fixing member 18 is made of a steel material.

The flooring-defining plurality of floorings 20 are arranged so that their edges are in contact with each other in the extending direction of the joist 16 and their side surfaces are in contact with each other in the direction orthogonal to the joist 16. A groove 32 including a shallow groove portion and a deep groove portion that are continuous with each other is provided in the fore edge of each flooring 20, and the shallow groove portion and the deep groove portion of the two grooves 32 of the fore edge of the pair of flooring 20 facing each other are respectively A part of the base portion 28 of the fixing member 18 and the flange portion 30 are passed through. Thereby, the flooring 20 is fixed to the joist 16. The fixing member 18 also acts to prevent the flooring 20 from being bent back.

The preferred water content of each flooring 20 is 5.8-6.2%, which is obtained by placing the flooring in a 150 ° C. oven and artificially drying. This water content value is almost the flooring drying limit. In the flooring 20 having a low water content including the above-mentioned range, when the heating fluid is passed through the conduit 24 for heating the flooring 20 for floor heating, the moisture radiated from the flooring 20 is remarkably small, and therefore, the water content is reduced. The shrinkage of the flooring 20 due to the decrease in the rate can be made extremely small. Further, the length dimension of the flooring is preferably set to 30 cm or less in consideration of its warpage property.

In the illustrated example, the coating 22 is made of a resin film 34 formed by applying a synthetic resin liquid such as urethane resin or acrylic resin on the surfaces of the plurality of floorings 20, and the side surfaces of the plurality of floorings 20 and The back surface is made of a waterproof sheet 36. More specifically, the peripheral portions of the surfaces of the plurality of floorings 20 are covered with the sheet 36. Further, in the illustrated example, the sheet 36 is in contact with the surface of the ground floor 14, and the back surfaces of the plurality of floorings 20 are covered with a space from the back surfaces, but the sheet 36 is the back surface of the flooring 20. You can also make contact with. . As a result of covering the plurality of floorings 20 with the coating 22, the flooring 20 is disconnected from the atmosphere and the subfloor 14 and absorbs moisture in the air and from the subfloor 14 to increase the water content. It is prevented from expanding. Therefore, the flooring 20 is maintained so that its expansion and contraction are very small, so that the flooring 20 hardly warps.

The conduit 22 formed of a plastic material such as polyethylene is fixed to the base floor 12 by a mounting member 38. The space around the conduit 24 is filled with a filler 40 containing, for example, dolomite plaster, sand, cement, and a synthetic resin liquid. The filler 40 has a higher heat conductivity than air, and efficiently guides the heat of the heating medium flowing through the conduit 24 to the flooring 20. As a result, the flooring 20 is heated.
