Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical type rainwater for storing rainwater, which is installed in a part of a building such as a house for use in car washing, watering a garden, and flushing a flush toilet. Water storage
It relates to the bottom fixing structure of the link .

[0002]

2. Description of the Related Art First, a background of utilizing rainwater will be described. Japan is one of the rainiest countries in the world, with an annual rainfall of about 1750 mm / m ^2, which is the world average of 970.
It is almost twice as large as mm / m ² . However, the population density is high, and the per capita population is about 5460 m ^3, which is the world average of 2687.
It is about ⅕ of 0 m ³ , and because of the steep topography, much rainwater immediately flows out into the sea through the river,
The amount of water available is even more limited, with only about 870 m ³ actually available. Under these circumstances, the amount of water supply has increased with the increase in urban areas these days.
Water shortages are becoming more serious. On the other hand, in urban areas, rainwater is drained directly into the sewer through the gutter and eventually flows into the sea, so groundwater cannot be secured, which increases the impervious area of groundwater. The rise in surface temperature is a factor that causes urban heat islands.

Under these circumstances, it is sufficient to use rainwater effectively for car washing and irrigation of gardens without using clean water, and the amount of clean water used can be saved accordingly. In addition, if rainwater is effectively used for irrigation and the like, it is possible to recharge groundwater. From the above, it has been attempted to adopt a structure for storing rainwater in the house so that rainwater can be effectively used. Japanese Patent Laid-Open No. 5-
Japanese Patent No. 295767 discloses a structure in which a large-capacity aquarium is provided at an appropriate place in a house.

[0004]

However, providing a water tank that requires a certain amount of capacity limits the design of the house due to its installation, complicates the construction process, and costs it. If possible, it is possible to easily install in a conventionally constructed house without considering the installation space of such an aquarium, and to save the installation space, and to effectively use the stored water for car washing, etc. A rainwater storage method is preferable. In addition, along with this, we would like to make the tank structure for water storage that requires piping work simple in structure and easy to carry out piping work, and further to take up no space for installation.

In such a situation, using the space under the eaves,
A vertical type vertical rainwater storage tank that can be installed vertically, which does not take up space horizontally and can be distributed by utilizing the weight of water without using a power source such as a pump, has been introduced. The problem with this is that since the tank is vertical, a large load is applied to the bottom, and a vibration-proof structure against vibration such as an earthquake is required.

Further, if piping is provided from the bottom of the tank in order to enable high-pressure water distribution by utilizing the weight of water in the tank, if the bottom is in contact with the ground, the piping will be underground. Buried construction is required. This is an obstacle to installing such a tank at low cost and with easy construction.

[0007]

The present invention uses the following means in order to solve the above problems. Claim

The arrangement and use of the vertical rainwater storage tank VT of the present invention in a house will be described with reference to FIG. The house shown in FIG. 1 is a two-story building, and has a structure in which the roof between the first and second floors is not provided and the roof R is arranged at the top. The vertical rainwater storage tank VT of the present invention is erected vertically from below the eaves of the roof R to the floor height of the first floor. The rainwater stored in the tank is first used as cleaning water for the toilet WC arranged on the first floor. A toilet may be provided on the second floor so that the toilet wash water is introduced from the middle of the tank.

[0012] Around the house, soil is laid, planting P is provided, and a home garden F is provided. The water in the vertical rainwater storage tank VT is used for watering these. To do. A horizontal rainwater storage tank LT is arranged next to the parking lot PK, and is used for flushing the toilet, washing the car, and watering the planting P and the home garden F. In this way, the water for toilet flushing, car washing, water sprinkling, and planting and raising is usually stored by rainwater, so it is possible to sprinkle water even when the water is short, and the amount of tap water used is reduced. You can save. Further, for planting and growing, the pavement H leading to the parking lot PK is made water-permeable, and the surrounding block BL is also made water-permeable so that rainwater can sufficiently penetrate into the soil in rainy weather. I have to. In the past, these were not water permeable, but when it rained, rainwater flowed on the surface and flowed out to the gutters, and the water retention capacity of the soil was weak. It became.

In this way, if rainwater can be effectively used for sprinkling, the area of planting P can be increased without increasing the amount of water supply used. If the planting P is effectively used and the vine plants are grown so as to cover the upper part and the lateral part of the terrace, as in the house shown in FIG. 1, for example, in the summer, the sunshine is blocked and the temperature rise in the room is suppressed. In the winter, by dropping more leaves, it takes in much sunlight and raises the indoor temperature, so it exerts a natural indoor temperature control function and saves heating and cooling costs.
Above all, it gives a pleasing appearance, and can also give a refreshing blessing to people passing outside the house.

In this way, effective use of rainwater is
It contributes greatly to the saving of clean water, measures against water shortage, and planting and raising. Among them, the vertical rainwater storage tank VT according to the present invention, particularly the bottom fixing structure, will be described below.

The structure of the vertical rainwater storage tank VT is roughly described. The upper end of the main body tank 1 which is a vertically long cylindrical body is open, and rainwater is supplied from the gutter G provided along the roof. When introduced, rainwater is stored in the main body tank 1. In addition to this, in FIGS. 9 and 10 described later, a water supply pipe 10 is provided at the bottom of the tank, and rainwater is introduced into the main body tank 1 through the water supply pipe 10. Further, a bottom lid 2 is provided on the bottom portion, and various water conduits are introduced into the main body tank 1 via the bottom lid 2. Further, water intake plugs V are attached to the side surfaces of the main body tank 1 and the bottom cover 2 as shown in FIGS.

The vertical rainwater tank VT having such a structure is
As mentioned above, it is erected vertically using the space under the eaves, but when supporting the bottom of the eaves, first of all, because it is vertical, it supports a large hydraulic load on the bottom and supports earthquakes, etc. Need to be strong against vibration. If you bury the bottom in the ground, you can handle these things,
On the other hand, as described above, since various water conduits are piped below the bottom cover 2, this makes pipe construction difficult.
That is, in order to facilitate the pipe construction, it is necessary to arrange the bottom part at a position at a certain height above the ground.

Therefore, the foundation B of the building is extended outward to form a foundation extension portion Ba, a pedestal is fixedly mounted on the foundation extension portion Ba, and the tank bottom portion is placed on the pedestal. 2 to 8 disclose the pedestal 3 and FIGS. 9 to 13 disclose the pedestal 4, but both of them have the same fixing structure to the base extension portion Ba, so here, the pedestal 3 is fixed. The structure will be explained. Saddle plates 3a and 3a (saddle plates 4a and 4a in the pedestal 4) are hung from the bottom surface of the pedestal 3 in parallel, and when the saddle plates 3a and 3a are fixed to the foundation extension part Ba, The bottom surface of the pedestal 3 is brought into contact with the top surface of the base extension portion Ba so that the base extension portion Ba is attached to the side surface of the base extension portion Ba, and the base extension portion Ba is attached to both the saddle plates 3.
It is sandwiched between a and 3a, and both saddle plates 3a and 3a
Anchor bolt AB (shown in FIG. 3) on the foundation extension portion Ba
It will be tightened at. In this way, the pedestals 3 and 4 are fixedly provided on the upper portion of the base extension portion Ba, so that the pedestals 3 and 4 are arranged at a certain height above the ground, and the piping space can be held below the pedestals 3 and 4.

The pedestals 3 and 4 are made of a rigid member such as a metal material so as to withstand a large load from the tank. Further, on both saddle plates 3a, 3a, reinforcing rib plates 3b, 3b ... (Reinforcing rib plates 4b, 4b. Even if the tank vibrates due to an earthquake or the like, the pedestal 3 (4) is supported from below by these reinforcing rib plates 3b (4b) and does not follow the vibration, and is integrally formed with the foundation extension Ba. It remains fixed.

However, with respect to the pedestal 3 (4) which is integrally formed with the base extension portion Ba and whose amplitude is suppressed as described above,
If a tank with a large amplitude (in which the main body tank 1 and the bottom lid 2 are integrated) vibrates, the friction between the tank bottom and the pedestal is severe, and the tank bottom may be immediately damaged. Therefore, FIG. 3, FIG. 6A, and FIG.
As shown in (a), the cushioning material 6 made of an elastic material is attached to the inner upper surface of the bottom plate of the pedestal 3 (4) and the inner side surface of the side plate. The cushioning material 6 is mainly made of rubber, and other materials such as synthetic resin having elasticity and absorbing vibration of the bottom of the tank are used. By thus interposing the cushioning material 6, it is possible to avoid damage to the bottom of the tank even during vibration. As described above, the pedestal 3 (4) fixed to the foundation extension portion Ba is provided with a sufficient seismic structure.

Next, the piping structure will be described. First,
In the pedestal 3, as shown in FIGS. 2 and 4, in order to connect the piping only to one side of the foundation extension portion Ba, the pedestal 3 shown in FIGS.
As described above, the piping holes 3c, 3d, and 3e are formed in the bottom plate portion at the outer position of the one saddle plate 3a. (Cushioning material 6
Also, a hole is formed along with it. ) An overflow pipe 7 is inserted into the pipe hole 3c having a large central diameter as shown in FIG. The overflow pipe 7 is vertically long in the main body tank 1 and is a pipe for overflowing rainwater stored from the upper end opening in the main body tank 1 so as not to overflow.

The pipe provided with the opening / closing plug 8a on the side thereof is the drain pipe 8, and water in the tank can be drained by opening the opening / closing plug 8a, thereby purifying the stored water in the tank. Can be achieved. On the other side, the water distribution pipe 9 is provided for the flush toilet WC as described above, or for watering the planting P or the like. 2 to 5 using the pedestal 3 as described above.
In the illustrated embodiment, the overflow pipe 7, the drain pipe 8 and the water distribution pipe 9 are provided only on one side of the base extension portion Ba.

On the other hand, in the embodiment shown in FIGS.
As shown in FIG. 1 and FIG. 12, on one outer side of the saddle plate 4a of the pedestal 4, piping holes 4c, 4d, and 4e similar to the piping holes 3c, 3d, and 3e of the pedestal 3 are formed. Piping holes 4f are also formed on the outside of the other saddle plate 4a. The drain pipes 8 and the water distribution pipes 9 are fitted into the pipe holes 4d and 4e similarly to the pipe holes 3d and 3e. Water pipe 9
9 and 10, in particular, a hole Bb for piping is bored in the foundation B, the hole Bb for piping is fitted and the pipe 9a for toilet cleaning is branched and piped in the building. In addition, the main plumbing is piped for watering outside the building.

A water supply pipe 10 for supplying rainwater into the main body tank 1 is fitted into the pipe hole 4c on the same side as the pipe holes 4d and 4e with respect to the base extension Ba.
An overflow pipe 7'is inserted into the piping hole 4f on the opposite side. That is, the vertical rainwater storage tank VT in this case
In the above, the rainwater is introduced into the main body tank 1 by the water supply pipe 10 and is distributed from the overflow pipe 7 ′ which is arranged on the opposite side across the base extension portion Ba so that the rainwater flow passage is formed in one direction. In addition, the main body tank 1
It is possible to install continuously.

In the above embodiments, it is necessary to construct the base extension portion Ba from the base B. That is, at the construction stage of the building, it is necessary to preliminarily perform basic construction assuming that the vertical rainwater storage tank VT will be attached. However, in consideration of future spread, it is necessary to be able to arrange the vertical rainwater storage tank VT even in an existing building. The reason why the foundation extension portion Ba is newly constructed is that not only is construction difficult, but there are many cases where there is no construction site. To do this, the bottom of the tank must be supported at a certain height above the ground (for easy piping work) regardless of the foundation. Of course, the support structure must have a vibration isolation structure.

An embodiment in which the vertical rainwater storage tank T is supported by using the pedestal 5 will be described with reference to FIGS. First, the structure of the pedestal 5 will be described with reference to FIGS. 16 to 18. The sheath pipe 5a is vertically downward from the bottom plate of the pedestal 5.
Between the sheath pipe 5a and the pedestal bottom plate, reinforcing ribs 5c, 5c ... Having a triangular shape in a side view are radially arranged to reinforce the pedestal 5. In addition, a telescopic pile 5d is slidably fitted in the sheath pipe 5a, while height adjusting holes 5b, 5b ... Are formed in the sheath pipe 5a. 5b is selected, a bolt is inserted, and the expansion pile 5d is fixed to a constant length. Thereby, the height of the pedestal 5 is adjusted.

In the pedestal 5 whose height can be adjusted in this way, as shown in FIGS. 14 and 15, the expansion piles 5c are driven and embedded in the ground to directly mount the pedestal 5 without using the foundation of the building. It can be installed upright from the ground. As in the case of the pedestals 3 and 4, a cushioning material 6 is attached to the inner surface of the bottom plate of the pedestal 5 thus erected in the same manner as in the case of the pedestals 3 and 4 in order to buffer interference with the tank bottom portion during vibration. There is. In the vertical rainwater storage tank VT of this embodiment, only the overflow pipe 7 ″ is vertically provided from the bottom of the bottom, and the pipe hole 5e is formed in the pedestal bottom plate so that the overflow pipe 7 ″ can be fitted. Has been drilled. Further, in the vertical rainwater storage tank VT of this embodiment, the water intake plug V is provided on the side surface of the main body tank 1 and the bottom lid 2 as in the above-described embodiment, and the drain port 11 is provided on the side surface. . The drain port 11
A flange 12 is provided on the front side, and the flange 12 is fastened and closed when not draining.

Thus, even if the base extension portion Ba is not provided, by mounting the pedestal 5 on the ground, the bottom of the tank can be supported at a constant height above the ground, and like the overflow pipe 7 ", It becomes possible to construct piping below the bottom of the tank, and between the pedestal portion and the sheath pipe 5a and the expansion / contraction pile 5c interposed between the ground and the pedestal 5, the reinforcing rib 5 is provided.
It is supported by b, and the sheath pipe 5 is used even during vibration such as an earthquake.
It has a seismic resistant structure without cracks at the root of a. Further, by attaching the cushioning material 6, it is possible to avoid the interference between the tank and the pedestal, and the tank is not damaged.

[0028]

The present invention having the above-described structure has the following effects. That is, in the structure for fixing the bottom portion of the vertical rainwater storage tank to the pedestal by configuring as in claim 1, by the cushioning material attached to the pedestal,
Even during vibration such as an earthquake, interference between the bottom of the tank and the pedestal is avoided, and the bottom of the tank is protected. In addition, by forming the piping hole, piping such as an overflow pipe downward from the tank bottom can be easily installed by only penetrating the pedestal. Further, by fixing the pedestal in a state that the upper part of the foundation extension of the building is sandwiched, the pedestal can be arranged at a constant height above the ground, and the above-mentioned piping hole is provided in the foundation extension. Combined with drilling at the outer position, the piping from the tank bottom below the pedestal does not interfere with the foundation extension,
Can be easily installed. Further, since the pedestal is fixedly mounted in a state of sandwiching the foundation extension, it becomes integral with the foundation extension, and the structure is such that vibration of the pedestal is small even during an earthquake or the like.

According to the second aspect of the present invention, when it is difficult to construct the foundation extension as in the first aspect, the pile can be directly driven to the ground without providing the extension. As a result, the pedestal can be erected at a constant height, and similarly to the above, the structure is such that piping from the tank bottom to the lower part can be facilitated. In addition, the height of the pedestal can be easily adjusted by making the pile expandable and contractible.

According to the above-mentioned constructions of the present invention, the vertical rainwater storage tank is easily constructed and is supported by a pedestal having an earthquake resistance, avoiding interference with the bottom of the tank even during an earthquake. Since it is easy to install piping from the bottom to the bottom, it is possible to take water by the weight of the stored water in the tank,
The use of power pumps can also be dispensed with. Therefore,
Since it is possible to realize a vertical rainwater storage tank that is easy to construct, low cost, and stable, it is possible to expect the spread of this tank, which contributes to the elimination of water shortage by effective use of rainwater and the securing of soil water retention. it can.
