  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  Referring to FIG. 1, in the water tank installation method according to an embodiment of the present invention, water tank 10 is fixedly installed on a housing of a general house such as an apartment or a detached house. Here, the frame refers to a framework that supports the structure of a building, and includes a concrete slab 100, a beam 108, a column, and the like.

  As shown in FIGS. 2 to 7, the water storage tank 10 includes a tank body 12, a frame 14, and a case 16, and stores clean water that can be used as drinking water in an emergency. The water storage tank 10 connects a first water supply pipe that supplies tap water from the water pipe into the house and a plurality of second water supply pipes that distribute the tap water supplied by the first water supply pipe to each water tap. That is, the water storage tank 10 is provided in the water supply system pipeline, stores clean water, and also functions as a water supply header. The internal volume of the water storage tank 10 is, for example, 36 liters, and this amount corresponds to the amount of drinking water used for 3 days by a family of four. In this embodiment, the water storage tank 10 includes two tank bodies 12.

  Referring to FIGS. 2 to 4, tank body 12 is a part for storing water, is formed of a synthetic resin such as hard vinyl chloride and polyethylene, and includes a pipe part 18 and a cap part 20. The pipe portion 18 is a circular tube having both ends open, that is, a general-purpose synthetic resin pipe, and cap portions 20 are provided at both ends thereof. The inner diameter and length of the pipe part 18 are appropriately set according to the amount of water to be stored. For example, in this embodiment, 18 liters of water is stored in one tank body 12 by forming the pipe part 18 using a circular pipe having an inner diameter of 146 mm and having a length of about 1.1 m. .

  The cap part 20 is connected to each of the outer surfaces of both ends of the pipe part 18 by the TS bonding method, the first cap part 20a connected to one end side of the pipe part 18 and the second cap connected to the other end side. Part 20b. The cap unit 20 includes a short cylindrical side wall 22 and a disk-shaped disk unit 24 that seals one end of the side wall 22. The inner surface of the side wall 22 is located outside the inner surface of the tube portion 18, and a space is formed between the disc portion 24 and the end surface of the tube portion 18. Further, the disk portion 24 is formed with two receiving ports 26 protruding in parallel to the axial direction in a direction away from the tube portion 18. The two receiving ports 26 are respectively formed on the upper and lower portions of the disc portion 24, and the upper inner surface of the first receiving port 26 a located at the upper portion is smoothly connected to the upper inner surface of the side wall 22, and is located at the lower portion. The lower part of the inner surface of the two receiving ports 26b is smoothly connected to the lower part of the inner surface of the side wall 22. That is, the first receiving port 26a is higher than the uppermost part of the inner surface of the pipe part 18, and the second receiving port 26b is lower than the lowermost part of the inner surface of the pipe part 18 and the disk part 24 and the pipe. It communicates with the space formed between the end faces of the portion 18.

  The first receiving port 26a of the first cap portion 20a functions as an introduction port and is connected to the introduction tube 28. The introduction pipe 28 is connected to the introduction pipe 28 from the other tank body 12, and extends to the second cap portion 20b side through the space between the two tank bodies 12 while maintaining its height. A first connection part 30 connected to a first water supply pipe (not shown) is provided at the end of the introduction pipe 28. The introduction pipe 28 is provided with a valve 32 and a check valve built in the valve 32.

  The second receiving port 26b of the first cap portion 20a functions as a water supply port and is connected to the first outlet pipe 34. The first lead-out pipe 34 is connected to the first lead-out pipe 34 from the other tank main body 12 and extends between the two tank main bodies 12 while maintaining the height thereof and extends toward the second cap portion 20b. A second connection portion 36 connected to an emergency second water supply pipe (not shown) is provided at the end of the first outlet pipe 34. The emergency second water supply pipe is normally used as a water intake tap in normal times, and is connected to a water supply tap used as an emergency water intake tap in an emergency (when water is shut off), for example, a kitchen water tap.

  The first receiving port 26a of the second cap portion 20b functions as a water supply port and is connected to the second outlet pipe 38. The second lead-out pipe 38 extends in a direction away from the second cap portion 20b while maintaining its height. A third connection portion 40 connected to a normal second water supply pipe (not shown) is provided at the end of the second outlet pipe 38. The normal second water supply pipe is connected to each water faucet except for the one used as an emergency water faucet, for example, a water faucet in a toilet or bathroom.

  Similarly to the first receiving port 26a of the second cap part 20b, the second receiving port 26b of the second cap part 20b functions as a water supply port and is connected to the second outlet pipe 38. The second lead-out pipe 38 connected to the second receiving port 26b bends upward, becomes the same height as the second lead-out pipe 38 connected to the first receiving port 26a, and is separated from the second cap portion 20b. Extend in the direction. In addition, an intake port is formed in the second outlet pipe 38 connected to the second receiving port 26b, and an intake valve 42 for preventing a siphon phenomenon is provided at the intake port.

  The tank body 12 is provided with a connecting body 44. The connecting body 44 is a member for connecting and fixing the tank body 12 and the frame 14. Moreover, in this Example, since the water storage tank 10 is provided with the two tank main bodies 12, the connection body 44 functions also as a member which connects the tank main bodies 12 mutually. Specifically, the connecting body 44 is formed of a metal such as stainless steel, and is combined with a short semi-cylindrical connecting body member whose both ends bend outward, thereby sandwiching and connecting the tank body 12. It is formed in glasses. In this embodiment, two connecting bodies 44 are respectively attached to the outer surface of the pipe portion 18 in the vicinity of the cap portion 20. Moreover, the space | interval formed in the up-down direction is provided in the both ends 44a of the connection body 44 within the height range of the tank main body 12. FIG. A first frame 48 (to be described later) is fitted into this interval and bolted to connect the connecting body 44 and the frame 14.

  Further, when attaching the connecting body 44 to the pipe portion 18, a heat insulating material 46 formed of urethane or the like is sandwiched between the pipe portion 18 and the connecting body 44. When there is a difference between the temperature in the pipe portion 18 and the temperature of the connecting body 44, if the pipe portion 18 and the connecting body 44 are in direct contact with each other, condensation may occur at the contact portion. 46 prevents it. Moreover, even if an earthquake occurs and the whole water storage tank 10 shakes by attaching the coupling body 44 to the pipe part 18 via the heat insulating material 46 which has elasticity, the shaking is absorbed by the elasticity of the heat insulating material 46, Damage to the pipe portion 18 is prevented.

  The frame 14 is formed in a planar rectangular shape surrounding the two tank bodies 12 by a metal such as stainless steel. The frame 14 supports the tank body 12 via the above-described connecting body 44 and the like, and functions as an attachment for attaching the water storage tank 10 to the building. When forming the frame 14, a general-purpose shape steel such as a grooved steel can be used.

  Specifically, the frame 14 includes a first frame 48 and a second frame 50, and the first frame 48 is connected to each of both end portions 44 a of the connection body 44 so as to connect the two connection bodies 44. . That is, the first frame 48 is provided on each side of the tank body 12 within the height range of the tank body 12 and extends in the length direction of the tank body 12. The first frame 48 has a groove-shaped cross-sectional shape that opens outward, and has a length longer than that of the tank body 12. For example, the first frame 48 has a length of 1360 mm, a width of 30 mm, and a height of 60 mm.

  Further, the first frame 48 is formed with an attachment portion 52 that is used when the water tank 10 is attached to a building. The attachment portion 52 is, for example, a substantially elliptical hole that allows the first frame 48 to communicate in the vertical direction, and a suspension bolt 102 and the like to be described later are inserted into the hole. The attachment portion 52 is formed at a position in consideration of the weight balance when the water tank 10 is attached to the building. In this embodiment, a total of four attachment portions 52 are formed in the vicinity of the end portion of the connection body 44. The

  The second frame 50 is connected to the two first frames 48 on the outer side of the end face of the tank body 12 to increase the strength of the frame 14 and thus the strength of the water storage tank 10. The second frame 50 is bolted and fixed to the first frame 48 via a metal fitting such as an L angle. The length of the second frame 50, that is, the distance between the two first frames 48 is, for example, 475 mm. Further, the second frame 50 on the second cap portion 20b side of the tank body 12 is formed so as to pass between the introduction pipe 28 and the second outlet pipe 38 and the first outlet pipe 34, and its width is The inlet pipe 28 and the second outlet pipe 38 are set to a size corresponding to the distance between the first outlet pipe 34. That is, the introduction pipe 28 and the second outlet pipe 38 are on the upper surface of the second frame 50 on the second cap portion 20b side, and the first outlet pipe 34 is along the lower surface thereof. Therefore, each pipe | tube 28,34,38 can be easily fixed to the 2nd flame | frame 50 by the side of the 2nd cap part 20b, and when each water supply pipe | tube is connected to each pipe | tube 28,34,38, Damage due to bending of the tubes 28, 34, 38 can be prevented.

  As shown in FIGS. 5 to 7, the water storage tank 10 includes a case 16, and the tank main body 12 and the pipes 28, 34, and 38 are stored horizontally in the case 16. The case 16 covers the tank body 12 and the tubes 28, 34, and 38 and keeps the temperature constant, and is used to improve the earthquake resistance of the water tank 10 as will be described in detail later.

  Specifically, the case 16 is formed of a foamed polystyrene having a heat retaining property and flame retardancy and an elastic material such as urethane, and is formed in a flat horizontally long box shape whose upper surface 16a and lower surface 16b are flat. For example, the upper part 54 and the lower part 56 of the case 16 are formed as separate bodies, and the upper part 54 and the lower part 56 are separated by using an adhesive or an adhesive tape after the tank body 12 is accommodated therein. It is integrated into a box shape. For example, the length of the case 16 is 1600 mm, its width is 535 mm, and its height is 240 mm.

  On both side surfaces 16 c of the case 16, recessed portions 58 having a size corresponding to the outer shape of the first frame 48 are formed. The first frame 48 is exposed from the both side surfaces 16 c of the case 16 so as to fit into the recess 58, and extends to the vicinity of both end surfaces 16 d of the case 16. Further, on both side surfaces 16 c of the case 16, cutout portions 60 that communicate with the upper and lower portions of the attachment portions 52 of the first frame 48 are formed. With this cutout portion 60, the attachment portion 52 is exposed in the vertical direction from the case 16, and a suspension bolt 102 or the like described later can be attached to the attachment portion 52.

  Further, a plurality (six in this embodiment) of connection ports 62 are provided on one end surface 16d of the case 16 at positions corresponding to the connection portions 30, 36, 40 provided on the pipes 28, 34, 38. The water pipes are formed and connected to the connection portions 30, 36, and 40 through the connection ports 62.

  In such a water tank 10, since the water in the tank main body 12 is automatically replaced every time tap water is used from each water tap in daily life, clean water can always be secured. In addition, since the tank body 12 is formed using a synthetic resin pipe, the tank body 12 has excellent mechanical properties, particularly flexibility, and the tank body 12 is cracked even if an earthquake occurs. hard. Further, since the tank body 12 and the frame 14 functioning as a fixture are integrated, and the frame 14 is provided so as to be within the height range of the tank body 12, the water tank 10 is installed in the building. The height dimension can be suppressed. Further, since the frame 14 is formed in a planar rectangular shape surrounding the tank body 12, the frame 14 is sufficiently strong, and the water tank 10 itself is sufficiently strong.

  Returning to FIG. 1, the water tank installation method is applied when the water tank 10 as described above is installed on the ceiling of a building or the like. Below, the case where the water tank 10 is installed in the apartment which has RC structure (reinforced concrete structure) is demonstrated. In this case, the water storage tank 10 is suspended and installed in a housing on the ceiling of the apartment, that is, a concrete slab (hereinafter, simply referred to as “slab”) 100.

  Specifically, as shown in FIGS. 1 and 8, first, suspension bolts 102 are provided on the slab 100 at intervals according to the positions of the attachment portions 52 of the first frame 48. Next, the water storage tank 10 is lifted from below, and the suspension bolts 102 are inserted into the attachment portions 52. At this time, a tubular reinforcing tool 104 formed of hard vinyl chloride or the like having impact resistance may be bitten so as to contact the inner surface of the first frame 48. Then, the upper surface 16a of the case 16 is brought into contact with the lower surface 100a of the slab 100, and in this state, the first frame 48 and the suspension bolt 102 are fixed appropriately using a nut or the like, and the water tank 10 is installed on the slab 100. .

  In this way, by adopting an installation structure in which the upper surface 16a of the case 16 is in contact with the lower surface 100a of the slab 100, the movement of the water tank 10 is synchronized with the movement of the slab 100 without distortion when an earthquake occurs. To do. That is, the water storage tank 10 only shakes with the slab 100 and is not affected by strain from the slab 100. Moreover, the vibration of the slab 100 due to the earthquake is absorbed by the elasticity of the case 16. Therefore, since the influence which the shaking of an earthquake has on the tank main body 12 can be reduced, the damage to the tank main body 12 can be prevented, and clean water in the tank main body 12 is ensured. That is, it is excellent in earthquake resistance.

  Moreover, the water tank 10 can be installed along the lower surface 100a of the slab 100 by making the shape of the case 16 into a flat horizontally long shape whose upper surface 16a is flat, that is, the lower surface 16b of the case 16 and the slab 100. Since the distance to the lower surface 100a of the slab 100 can be shortened, the movement of the water storage tank 10 is easily synchronized with the movement of the slab 100. Moreover, since the contact area with the lower surface 100a of the slab 100 is increased, the vibration of the slab 100 due to the earthquake is easily absorbed by the elasticity of the case 16.

  Furthermore, since the water storage tank 10 is not placed and installed on the ceiling material 106 provided under the slab 100 (the same applies to a beam 108 described later), the water storage tank 10 is suspended and installed on the slab 100. In comparison, the ceiling material 106 having a lower strength is not damaged during an earthquake and falls together with the water tank 10.

  In addition, although the above-mentioned Example demonstrated the case where the water tank 10 was installed in the apartment which has RC structure (reinforced concrete structure), the installation method of a water tank is when installing the water tank 10 in a wooden building. Is also applicable. In this case, as shown in FIG. 9, the water storage tank 10 is suspended and installed on a frame on the ceiling of a wooden building, that is, a beam 108.

  Specifically, an L angle 110 is fixed to the beam 108 and a suspension bolt 102 is attached to the L angle 110. Then, similarly to the case where it is installed in the slab 100, the tank body 10 is lifted from below, the suspension bolts 102 are inserted into each of the attachment portions 52, the upper surface 16a of the case 16 is brought into contact with the lower surface 108a of the beam 108, Fix with nuts as appropriate. Even if it does in this way, since the motion of the water tank 10 synchronizes with the motion of the beam 108 without a distortion | strain, the shake by an earthquake is absorbed by the elasticity of the case 16, and it is excellent in earthquake resistance.

  Moreover, in the above-mentioned Example, although the water storage tank 10 was installed in the housing | casing using the flame | frame 14 provided in the height range of the tank main body 12, it is not limited to this. For example, the frame 14 may be provided at a position that deviates from the height range of the tank body 12, and the water storage tank 10 may be installed on the housing using the frame 14.

  Further, instead of using the frame 14 provided in the water storage tank 10, for example, as shown in FIG. 10, the water storage tank 10 is installed in the housing by using a fixture 112 separate from the water storage tank 10. You can also. In this case, for example, when the water storage tank 10 is installed, a plurality of suspension bolts 102 are arranged on the slab 100 in a position along the both side surfaces 16 c of the case 16. Next, the water storage tank 10 is lifted, and the upper surface 16 a of the case 16 is brought into contact with the lower surface 100 a of the slab 100 so as to pass between the suspension bolts 102. And in this state, the attachment tool 112 formed with grooved steel etc. is passed between the suspension bolts 102 installed along the both side surfaces 16c of the case 16, and the water storage tank 10 is moved from below by the attachment tool 112. The fixture 112 and the suspension bolt 102 are appropriately fixed with a nut or the like so as to be supported. At this time, the water storage tank 10 and the suspension bolt 102 or the fixture 112 are appropriately fixed so that the water storage tank 10 does not shift laterally.

  The reason for installing the water storage tank 10 on the back of the ceiling of the building as in the above-described embodiment is to install the water storage tank 10 at a position higher than the water tap used as an emergency water intake tap. Thereby, in emergency, the water in the water storage tank 10 can be taken out from the emergency intake tap by natural flow.

  However, the installation method of the water storage tank can be applied not only when the water storage tank 10 is installed by being suspended from the slab 100 or the beam 108 on the back of the ceiling, but also when the water storage tank 10 is installed under the floor or the like. For example, when installing the water storage tank 10 under the floor, a bolt is driven on the concrete foundation under the floor, the bolt is inserted into the mounting portion 52, and the lower surface 16b of the case 16 is brought into contact with the upper surface of the concrete foundation. It is good to fix with a nut etc. suitably. Even if it does in this way, since the motion of the water storage tank 10 synchronizes with the motion of a concrete foundation without a distortion | strain, the shake by an earthquake is absorbed by the elasticity of the case 16, and it is excellent in earthquake resistance. In addition, when installing the water storage tank 10 under the floor of a detached house, since it is difficult to take out the stored water in the water storage tank 10 by natural flow, a separate water intake is provided at the upper part of the main body 12 of the tank. It may be necessary to remove the stored water from the intake. However, for example, in the case of an apartment house, it is possible to install the water storage tank 10 in the common area and take out the stored water downstairs.

  Moreover, in the above-mentioned Example, the water storage tank 10 provided with the case 16 which accommodates the tank main body 12 horizontally is assumed, and the water storage tank 10 was installed in the housing | casing which extends in the horizontal direction, such as the slab 100, but this It is not limited to. For example, when installing the water storage tank 10 provided with the vertically long case 16 for storing the tank main body 12 in a vertical position, the side surface of the vertically long case 16 is brought into contact with the side surface of a vertically extending casing such as a pillar. In addition, the water storage tank 10 can be fixed to the housing. In this case, the side surface of the vertically long case 16 corresponds to the upper surface 16 a of the horizontally long case 16.

  Moreover, the housing which installs the water tank 10 is not limited to the thing in a building. For example, the water storage tank 10 can be installed in a frame such as a pillar whose surface is exposed outside the building. In this case, it is preferable to cover the entire water storage tank 10 with a protective member. Even when the water tank 10 is provided outside the building, the stored water can be taken out from the building.

  Furthermore, the shape of the case 16 covering the tank body 12 is not limited to a flat horizontally long shape, and an appropriate shape can be adopted according to the shape of the casing surface to be brought into contact. For example, a cylindrical case 16 may be employed. However, the shape which can take large contact area with a housing | casing surface and can be installed along a housing | casing surface is preferable.
