A sewage drainage unit 20 for draining dewdrops formed on the concrete layer 19 and sewage such as sweat of bathers to the outside, 20 is formed in a slatted shape with wood, ceramic, synthetic resin, etc. and is covered with the passage concrete layer 19 Walking board, 2 1 is a ventilator disposed on the ceiling 2c, 21a is connected to the ventilator 21 and opens in the upper part of the front wall 2d side near the ceiling 2c of the bathroom 2 (see FIG. 2), and the interior of the bathroom 2 An exhaust port 21b for supplying outside air to the interior of the bathroom 2 is connected to the ventilator 21 through the ceiling 2c and opens at the upper part of the rear wall 2e near the ceiling 2c of the bathroom 2 (see FIG. 2). It is an intake port for sending the air to the ventilator 21.

The floor part 2a, the side wall part 2b, and the ceiling part 2c of the bathroom 2 were formed by connecting a plurality of box culverts having a substantially square cross section. Thereby, it is only necessary to form the front wall 2d and the rear wall 2e with concrete blocks, concrete panels or the like at the site, and the work man-hours at the site can be reduced and the frame construction can be simplified.
In addition, by using a box culvert that has been pre-standardized and manufactured in the factory, a series of operations from rebar processing, bar arrangement to mold forming, and concrete placement can be performed in a stable environment. The bathroom 2 can be produced with high accuracy by eliminating the technical skill level of the worker and adverse effects of the weather, and productivity and reliability can be improved.
The side wall 2b and the ceiling 2c may be formed using a concrete panel instead of the box culvert, or the bathroom 2 may be formed by placing all the concrete on site.
The concrete panel is excellent in fire resistance by being formed of an inorganic incombustible material mainly composed of cement, cinnabar, inorganic filler and the like. In addition, when an actual sealing structure is formed by placing an elastic sealing material at a fitting portion for jointing concrete panels, the watertightness is excellent. Furthermore, a concrete panel can be produced by extrusion molding, and by forming a hollow structure, an air layer is formed inside, and the heat insulation effect can be enhanced.
In addition, a door (not shown) is provided at the entrance 2f of the bathroom 2 so as to allow access to a break room and a changing room (not shown) connected to the bathroom 2 and Ensuring airtightness and heat retention. In addition, when a windbreak room is formed between the bathroom 2 and the break room and changing room connected to the bathroom 2, it is difficult for the heat and moisture in the bathroom 2 to escape to the break room and changing room, and the sauna efficiency is reduced. Can be prevented.

As the heat insulating material for the outer wall heat insulating material layer 3, the bed heat insulating material layer 9, and the passage heat insulating material layer 16, heat insulating materials such as inorganic fibers such as glass wool and rock wool, foamed plastics such as polystyrene foam and urethane foam, and wooden fibers are used. A highly specific material was used. Further, the exterior material 3a having a mortar finish on the outer surface of a base material such as a waterproof plywood is disposed on the outer periphery of the outer wall heat insulating material layer 3, so that the outer wall heat insulating material layer 3 can be protected and the interior of the bathroom 2 can be protected. It can prevent water from entering and has excellent heat retention.
By forming the heat storage layer 5 in the bed part 4, the heat transmitted from the heating part 11 to the intermediate concrete layer 8 side can be stored, and the heat retention inside the bathroom 2 is excellent. Moreover, when the bedrock bath 1 is constructed in a place where the underground temperature is high, the geothermal heat transmitted from the underground to the floor 2a side can be stored and effectively used.
Further, since the bed portion 4 is formed at a position higher than the passage portion 15, the distance from the heating portion 11 embedded in the bed portion 4 to the ceiling portion 2c can be shortened, and the volume in the bathroom 2 is increased. Since the heat storage layer 5 can be thickened and the heat capacity can be increased, the entire bathroom 2 can be heated in a short time and the temperature of the heating unit 11 can be set low. It is excellent in heating efficiency and energy saving.

At the time of construction of the heat storage layer 5, air can be extracted by rolling the sandy sand, and the heat storage layer 5 can be tightened to prevent the bed portion 4 from sinking, thereby improving durability. In addition, by arranging the concrete block 6 on the outer surface of the heat storage layer 5, the heat storage layer 5 is easily rolled and the heat retaining property of the heat storage layer 5 is improved. The heat storage layer 5 can support the upper intermediate concrete layer 8, the bed portion heat insulating material layer 9, the radiator bedrock 13, and the like as the foundation of the bed portion 4 and is excellent in reliability. Moreover, while fixing the upper part of the concrete block 6 with the intermediate concrete layer 8, the bed part heat insulating material layer 9 can be supported and fixed.
A far-infrared reflective sheet such as an aluminum sheet or a ceramic coat sheet may be provided between the bed part heat insulating material layer 9 and the heating part 11. Thereby, since the far infrared rays generated from the heat generated from the heating unit 11 and the radiator rock 13 can be reflected to the side 2 in the bathroom, the infrared rays can be efficiently used to enhance the sauna effect, Excellent energy saving.

As the mesh streaks 10, those made of metal or synthetic resin were used. In particular, in the case of a synthetic resin, it is lightweight and excellent in workability and workability, and is excellent in durability and corrosion resistance. The heating part 11 can be reliably fixed at equal intervals by the mesh streaks 10, and heating spots are reduced.
A polybden tube, a cross-linked polyethylene tube, or the like was used as the heat pipe of the heating unit 11. This is because it was found to be excellent in durability, strength, light weight and excellent workability.
The thermal piping used for the heating unit 11 of the bed unit 4 was arranged so as to be a single stroke as shown in FIG. Thereby, the heat source 11a can be put together in one place, and it is excellent in workability and space-saving property.
In the present embodiment, the piping of the heating unit 11 is drawn in one stroke, but the piping may be divided on the left and right sides of the passage unit 15 and heated individually, for example. In particular, when the number of bed parts 4 is large or when the area of the bathroom 2 is large, the temperature can be set individually by dividing and heating the piping for each block, and temperature management is easy. In addition, by changing the set temperature, the plurality of bed portions 4 can be used separately for high temperature and low temperature. The bather can select the temperature of the bed part 4 according to his / her preference and is excellent in versatility and functionality.

The heating unit 11 can also be provided in the passage unit 15. At this time, the heating unit 11 is buried between the passage heat insulating material layer 16 and the passage concrete layer 19, but the heating unit 11 is securely fixed by arranging the mesh streaks 10 on the upper portion of the passage heat insulating material layer 16. can do. When the heating part 11 is provided in the passage part 15, the passage part 15 can be heated to uniformly heat the entire floor part 2 a of the bathroom 2, and the passage part 15 is warm and always moving when the passage part 15 is moved. The part 15 can be kept in a dry state, is hygienic, and has excellent safety without the bather falling down.
The heating unit 11 embedded in the passage unit 15 may be common with the bed unit 4 or may be independent. When the heating unit 11 of the passage unit 15 is independent, the heating temperature of the passage unit 15 can be set low or the heating can be stopped, which is excellent in versatility and energy saving.

  Further, in the present embodiment, a thermal pipe is used as the heating unit 11, but an electric heater or the like formed in a heat pipe or a sheet shape can be used instead. What applied ceramic powder to the surface of an electric heater can radiate far infrared rays, and can improve a sauna effect. In particular, by emitting far infrared rays having a wavelength that is easily absorbed by a human body of 8 μm to 14 μm, the body can be warmed from the core, which is efficient and excellent in energy saving. In addition, when a self-temperature controllable heater is used as an electric heater, a constant temperature can be maintained in a small current area, power consumption can be reduced, and energy saving is excellent.

The radiator forming the bedrock 13 of the bed part 4 includes natural ores such as lecite, protolith, radon ore, feldspar, tourmaline, radium ore, barley stone, granite, quartz, silica Artificial ceramics were used. These radiators were cut and polished into a flat plate shape, or a crushed material obtained by crushing and mixing with cement or the like was used to form a rock.
By embedding a plurality of tile-shaped radiator bedrocks 13 formed in a square shape in accordance with the size of the human body with the surface exposed on the upper surface of the bed part 4, Can be warmed by the far-infrared effect. The thickness of the radiator rock 13 was 5 mm to 30 mm. As the thickness of the radiator rock 13 becomes thinner than 5 mm, the strength of the rock radiator 13 becomes insufficient, and the far-infrared emissivity tends to decrease. As the thickness becomes thicker than 30 mm, the weight increases, so This is because it has been found that the installation workability of the battery tends to deteriorate and heat conduction tends to take time.
Further, tiles were laid so as to surround the outer periphery of the radiator rock 13 to form the rock surrounding 13a. Thereby, the touch is good at the time of supine or lying down, and it is possible to prevent injuries of bathers and the like, and it is excellent in safety.

By forming the bed part side wall 13b on the outer periphery of the bed part 4 with a tile or the like, the heat storage property and energy saving property of the bed part 4 are improved. In addition, when the powder of the radiator which radiates electromagnetic waves such as far infrared rays similar to the radiator rock 13 is mixed in the upper concrete layer 12 or applied to the surface of the upper concrete layer 12, the heat and heat storage of the heating unit 11 Far infrared rays can be radiated from the entire surface of the bed part 4 using the heat stored in the layer 5, the bather's body can be warmed effectively, and the sauna effect can be enhanced.
Further, partition plates 14 are provided between the adjacent bed portions 4 and the bed portions 4 and between the bed portion 4 and the passage portion 15. As a result, the line of sight from other users can be blocked, the user can use it calmly, and the relaxation effect can be enhanced. By partitioning between the bed part 4 and the bed part 4 by the partition plate 14, when the sweat of the bed part 4 is washed away by a shower or the like, it is possible to prevent sewage from flowing to the other adjacent bed parts 4 and hygiene. And easy to maintain. In addition, it is excellent in the drainage property at the time of cleaning by inclining and forming the bed part 4 so that the channel | path part 15 side may become low.

The passage concrete layer 19 of the passage portion 15 was formed so as to be inclined toward the sewage drainage portion 19a. This makes it possible to drain sewage such as condensed water droplets and bather's sweat reliably and promptly from the sewage drainage section 19a, which is excellent in cleaning workability, hygienic and practical.
In the present embodiment, only the passage concrete layer 19 is inclined. However, when the floor 2a of the bathroom 2 is formed of a precast concrete frame such as a box culvert, a portion corresponding to the floor 2a is preliminarily 1 °. It can be formed with an inclination of ˜3 °, and the number of on-site steps can be reduced and workability can be improved.
In addition, when a drain pipe is embed | buried in the longitudinal direction of the passage concrete layer 19, the process which penetrates the passage heat insulating material layer 16 and the floor part 2a becomes unnecessary, and piping of a drain pipe is easy and it is excellent in workability.

A snowboard-shaped walking board 20 was laid over the upper part of the passage concrete layer 19. Accordingly, since the sewage such as sweat of the bather falls and flows under the walking board 20, the upper surface of the walking board 20 can be kept clean, and the sewage is directly touched when the bather moves. It is difficult and hygienic. When tiles or the like are laid on the upper surface of the passage concrete layer 19, the walking board 20 need not be laid. It is possible to protect the passage concrete layer 19 by preventing the passage concrete layer 19 from being exposed on the surface, and to prevent injury even if the surface of the bath is touched by the hand or foot of the bather, etc. It is hygienic and reliable.
In the present embodiment, the bed portion 4 is arranged in parallel with the passage portion 15 and arranged in a substantially U shape. However, the number and arrangement can be appropriately changed according to the size of the bathroom 2.

  The interior of the bathroom 2 was ventilated by a heat exchange type ventilation device 21. Since the outdoor air can be taken close to the temperature in the bathroom 2, the dirty air in the bathroom 2 can be efficiently replaced with fresh outdoor air while minimizing changes in the room temperature due to ventilation. Can do. In addition, the humidity can be controlled at the same time, and the efficiency is excellent without reducing the sauna effect. In the present embodiment, one intake port 21a and one exhaust port 21b are provided on the entrance / exit 2f side and the back side of the bathroom 2, respectively. Can be provided. The ventilator main body 21 may be installed in a place where it is not affected by heat in the bathroom 2, and may be disposed in a break room, a changing room, etc. connected to the bathroom 2. When installed indoors, it is not exposed to wind and rain and has excellent durability.

Next, a modified example of the bed part will be described.
FIG. 4 is a main part perspective view showing a modification of the bed portion of the bedrock bath in the first embodiment.
