Description

  The present invention relates to a grid having a rainwater storage function for storing rainwater that has fallen on the roof of a building and effectively using the rainwater.

  Conventionally, rainwater that has fallen on the roof has been collected in rainwater tanks for the use of rainwater, but the rainwater tank itself is bulky and heavy, and if installed near the building, it does not match the exterior of the building. I often feel a sense of discomfort and pressure. In addition, most of the installation locations are so-called narrow dog-running portions around the building, and if a rainwater tank is installed here, it will stick out on the road, and in most cases it will get in the way.

  Therefore, conventionally, along the outer wall surface of the house, vertical gutters and pipe-type rainwater tanks are installed in multiple stages extending in the horizontal direction, and the vertical gutters and each pipe-type rainwater tank are respectively connected via connecting pipes. A rainwater storage device connected by piping is known (for example, see Patent Document 1).

  However, in the conventional example shown in Patent Document 1, when the upper and lower multi-stage pipe-type rainwater tanks are installed along the wall surface of the house, the appearance is impaired, for example, a sense of incongruity with the building occurs. Moreover, the pipe portion connecting the downpipe and each pipe-type rainwater tank is exposed to the outside and is unsightly. In addition, since the grid length dimension in the horizontal direction of the pipe-type rainwater tank is standardized to a certain size, for example, the pipe-type rainwater tank can be adjusted according to the position of the window, etc. It also has the problem of becoming difficult.

  The present invention has been made in view of the above circumstances, and the object of the present invention is that it can be installed along the outer wall surface of the house with good appearance and without causing a feeling of pressure, and the degree of freedom in design conditions is increased. It is to provide a grid with a rainwater storage function that can be expanded with good looks.

  In order to solve the above-described problems, the present invention is characterized by the following configurations.

  It is a grid provided with a rainwater storage function installed along the outer wall surface of a house, wherein either one of the vertical grid 2 and the horizontal grid 3 is constituted by a cylindrical grid element body unit 4, and the other is at both ends. The cylindrical connecting body 5 is opened. The lattice element unit 4 includes a plurality of cylindrical bodies 6 divided in the length direction A and ends of the adjacent cylindrical bodies 6 arranged between the cylindrical bodies 6 and connected to each other. A tubular joint with a connecting function, which includes a plurality of tubular joints 7 having an upper connection port 7a and a lower connection port 7b that communicate with each other, and at least one tubular joint 7 can be connected to the tubular connection body 5. It consists of eight. By closing the lowermost part of the lattice element unit 4, a bottomed cylindrical water reservoir 9 is formed inside the lattice element unit 4, and a cylindrical joint 8 having a connecting function between adjacent lattice element units 4.

  As shown in FIG. 2, the plurality of lattice element units 4 constituting the vertical lattice are three lattice element units 4 having a water storage function (hereinafter referred to as “water storage unit 4A”). It is divided into one lattice element unit 4 (hereinafter referred to as “overflow unit 4B”) that functions as an overflow downspout.

  Each water storage unit 4 </ b> A is provided with a bottomed cylindrical water storage portion 9 that is long in the vertical direction, and each water storage portion 9 is connected to and communicated with each other via a cylindrical connector 5.

  A rainwater inlet 11 that opens upward is provided at the top of any one of the water reservoirs 9, and rainwater that flows into the eaves 52 (FIG. 1) from the roof 70 passes through the rainwater inlet 11. It is introduced into the reservoir 9. A rainwater outlet 12 connected to a stop cock 80 is provided in the vicinity of the lowermost portion of any one of the water storage sections 9, and rainwater collected in the water storage section 9 by opening the stop cock 80. Can be sprayed to the outside through the rainwater outlet 12 using watering means or the like.

  On the other hand, the upper end side of the overflow unit 4B communicates with the inside of the water storage portion 9 through the water-flowing cylindrical connecting body 5, and the cylindrical connecting body 5 on the lower end side of the overflow unit 4B is water stop means 13B. The water is stopped at. An overflow outlet 17 is provided at the bottom of the overflow unit 4B.

  Next, specific structures of the water storage unit 4A, the cylindrical connecting body 5, and the overflow unit 4B will be described.

  First, the specific structures of the water storage unit 4A and the cylindrical connector 5 will be described.

  As shown in FIG. 4, the water storage unit 4 </ b> A includes a plurality of cylindrical bodies 6 divided in the length direction A, and end portions of the adjacent cylindrical bodies 6 disposed between the cylindrical bodies 6. A plurality of cylindrical joints 7 that connect and communicate with each other are provided.

  Each of the tubular body 6 and the tubular joint 7 is formed in a hollow prismatic shape with both upper and lower ends opened, and the appearance of the entire water storage unit 4A is unified in a prismatic shape.

  As shown in FIG. 5A, the cylindrical joint 7 has an upper connection port 7 a and a lower connection port 7 b that are fitted and connected to end portions of the cylindrical body 6 adjacent to each other in the vertical direction.

  In the example of FIG. 4, for each lattice element unit 4, at least two tubular joints 7 are formed of tubular joints 8 with a connecting function that can be connected to the tubular connecting body 5 that becomes the horizontal lattice 3.

  In addition, the cylindrical connection body 5 used as the horizontal lattice 3 is formed in the hollow cylinder shape which both ends opened.

  The cylindrical joint 8 with a connecting function of this example projects the cylindrical connecting body 5 from one side as shown in FIG. 5 (b) in addition to the common configuration having the connection ports 7a and 7b at both upper and lower ends. The first tubular joint 8A, and the second tubular joint 8B having the tubular connection body 5 projecting from one side and the lateral connection port 20 being opened on the other side, as shown in FIG. 5 (c), As shown in FIG.5 (d), it classify | categorizes into the 3rd cylindrical joint 8C which opened the horizontal connection port 20 in one side surface. As shown in FIG. 4, the connection between the adjacent first cylindrical joint 8A and the second cylindrical joint 8B, the connection between the adjacent first cylindrical joint 8A and the third cylindrical joint 8C, and the adjacent first By appropriately combining the connection between the two cylindrical joints 8B and 2B and the connection between the adjacent second cylindrical joint 8B and the third cylindrical joint 8C, the plurality of lattice element units 4 and the plurality of cylindrical shapes are combined. The connection body 5 is combined and configured in a lattice shape.

  Here, an example of the connection method of the cylindrical connection body 5 with respect to the said cylindrical joint 8 with a connection function is shown in FIG. This connection auxiliary member 13 has two types, a water flow type connection auxiliary member 13A having both ends opened in FIG. 6A and a water stop type connection auxiliary member 13B in which the inside of FIG. 6B is closed. . The water flow type connection auxiliary member 13A is mainly used in the water storage unit 4A, and the water stop type connection auxiliary member 13B is mainly used in the overflow unit 4B described later.

  As for the connection auxiliary member 13, the flange part 21 and the insertion part 22 are formed in the cross-sectional hat shape, and as shown by the arrow of FIG.6 (c), the horizontal connection port 20 is made into the 1st cylindrical joint 8A from the inner side. It inserts toward the inner surface of the cylindrical connection body 5 protruding from the adjacent second cylindrical joint 8B. At this time, as shown in FIG. 6 (d), the adhesive 23 is applied to the outer surface of the connection auxiliary member 13, and then, as shown in FIG. 6 (e), the tip of the cylindrical connector 5 and the connection auxiliary member 13 are connected. By sandwiching the first cylindrical joint 8A with the flange portion 21, the cylindrical connector 5 and the first cylindrical joint 8A are joined and integrated. In addition, not only the joining by the adhesive agent 23 but it is also possible to use another fixing means for connecting and fixing the cylindrical connecting body 5 and the first cylindrical joint 8A, for example.

  Further, in the example of FIG. 4, the rainwater inlet 11 opened upward is connected to one end of the call basin 53 via the call bar elbow 54a, and the other end of the call bar 53 is connected to the eaves wall 52 via the call bar elbow 54b. The rainwater in the eaves wall 52 is connected to the rainwater inlet 11 via the call elbow 54a → calling ring 53 → calling elbow 54b. The call elbows 54a and 54b are waterproofly connected to the rainwater inlet 11 and the call 53, respectively, using an adhesive. Note that the top opening at the top of the water storage unit 4A other than the water storage unit 4A provided with the rainwater inlet 11 is closed by the upper lid 50, respectively.

  The bottom opening at the bottom of each water storage unit 4A is closed by a lower lid 51, whereby a bottomed cylindrical water storage portion 9 (long inside the water storage unit 4A extending in the vertical direction) ( FIG. 2) is formed. In this example, the upper lid 50 is inverted so that it can be shared as the lower lid 51.

  Next, the overflow unit 4B will be described.

  The overflow unit 4 </ b> B is composed of one lattice element body unit 4 located at one end of the plurality of lattice element units 4. The overflow unit 4B of this example is similar to the water storage unit 4A, and includes a plurality of tubular bodies 6, a tubular joint 7, a first tubular joint 8A divided in the length direction A (vertical direction in FIG. 4), It is composed of a third cylindrical joint 8C and the like. Each of these parts is unified in a prismatic appearance. The uppermost top opening of the overflow unit 4B is closed by an upper lid 50, and the lowermost part is an overflow outlet 17.

  Here, the horizontal connection port 20 (FIG. 5 (d)) of the uppermost third cylindrical joint 8C incorporated in the vicinity of the upper cover 50 of the overflow unit 4B and the vicinity of the uppermost portion of the water storage unit 4A adjacent thereto. The first cylindrical joint 8A is connected to the cylindrical connecting body 5 (FIG. 5B), and a water-permeable connection auxiliary member 13A (FIG. 6A) is provided inside the cylindrical connecting body 5. Inserted. This cylindrical connecting body 5 is located at the highest position than the other cylindrical connecting bodies 5, and the other cylindrical joints 8A and 8C other than the uppermost part of the overflow unit 4B are both water-stop type. The connection auxiliary member 13B (FIG. 6B) is connected to the tubular connection body 5 in a water-stopped state. Thereby, the overflow water from the inside of the water storage part 9 overflows in the overflow unit 4B only from the uppermost cylindrical connection body 5. FIG.

  One water storage unit 4C located at the other end on the opposite side to the overflow unit 4B is provided with a rainwater outlet 12 for taking out the stored rainwater to the outside. In the example of FIG. 4, the tubular connection body 5 protruding from the lowermost second tubular joint 8 </ b> B of the water storage unit 4 </ b> C functions as the rainwater outlet 12.

  Thus, in the grid 1 having the rainwater storage function having the above-described configuration, the rainwater flowing into the eaves 52 from the roof 70 at the time of raining flows from the rainwater inlet 11 as indicated by arrows a → b in FIG. Each of them flows into the water storage portion 9 in the water storage unit 4A and is temporarily stored, and can be used for sprinkling water from the rainwater outlet 12 by opening the stop cock 80 as necessary.

  On the other hand, when a large amount of rainwater flows in from the rainwater inlet 11 and the rainwater is filled in the water reservoir 9, excess rainwater flowing in from the rainwater inlet 11 is indicated by an arrow c in FIG. It overflows from the water flow-type tubular connecting body 5 connected to the vicinity of the uppermost part of the overflow unit 4B, and is discharged to the outside from the lowermost part of the overflow unit 4B.

  Here, on the construction side, the number of the cylindrical bodies 6 incorporated in the lattice element units 4 constituting the water storage unit 4A and the overflow unit 4B is increased or decreased, or the length dimension of the cylindrical body 6 itself is changed. The total length of the lattice element body unit 4 can be easily adjusted. Further, the total width of the grid 1 can be easily adjusted by increasing or decreasing the number of grid element units 4 used. Therefore, for example, the shape and size of the grid 1 can be changed as appropriate according to the height of the outer wall, the position of the window, and the like. As a result, unlike the conventional pipe type rainwater tank, the rainwater The degree of freedom of the design conditions of the grid 1 having a storage function is increased, and the addition of the grid 1 can be performed with good appearance.

  Moreover, in this example, the connection auxiliary member 13 inserted into the cylindrical connection body 5 can be used to connect the cylindrical connection body 5 and the cylindrical joint 8 and to prevent the connection portion from coming off and preventing water leakage. Therefore, there is no need to reinforce the connection portion to prevent it from coming off from the outside or to perform waterproofing, and the labor and cost for construction can be reduced. In addition, since the connection auxiliary member 13 is not exposed to the outside, the appearance of the lattice 1 is not impaired.

  Further, in terms of the external appearance, by connecting the plurality of lattice element units 4 constituting the water storage unit 4A and the overflow unit 4B to each other via the cylindrical connection body 5, the external appearance becomes a lattice shape, And it can give a rainwater storage function to itself. In addition, ventilation and lighting can be performed through the gaps between the lattice element units 4, and the distance between the lattice element units 4 can be uniformly ensured by the cylindrical connection body 5. In addition, the rainwater inlet 11 and the eaves wall 52 can be accommodated and connected well, creating a sense of unity between the eaves wall 52 and the grid 1, and as a result, there is no sense of incongruity when constructed, compared to conventional pipe-type rainwater tanks In addition, the design of the house is dramatically improved, and furthermore, by extending the lattice element unit 4 into a cylindrical shape, it is possible to suppress the protrusion to the outdoor side while securing the water storage amount. There is no need to stick out on the road side or obstruct traffic.

  Further, in terms of usage, excessive rainwater is discharged from the overflow unit 4B, so that rainwater does not flow back from the rainwater inlet 11 side during heavy rain and scatter to the surrounding outer wall or road side. Becomes better. In addition, since the lattice 1 has a large surface area, the amount of heat radiation is large, which is particularly useful for suppressing temperature rise in houses in summer.

  Next, an example of the wall surface fixture 14 for fixing the lattice element unit 4 is shown in FIG. The wall surface fixing tool 14 is fixed to the wall surface 10 (FIG. 1) using a fixing tool 35 such as a nail, and is formed from a substantially C-shaped bracket in which a pair of left and right lip-shaped latching portions 15 are projected from the front portion. Become. On the other hand, the tubular joint 8 with a connection function (first tubular joint 8A (FIG. 5B)), second tubular joint 8B (FIG. 5C), third tubular joint 8C (FIG. 5D) A pair of left and right claw-shaped hooking portions 16 project from the back of each of the cylindrical joints 8. By hooking the hooking portions 16 on the hooking portions 15, the cylindrical joints 8A to 8C are connected to each other. Each unit is hooked in a slidable state in the length direction A of the unit, and the size of the wall fixture 14 of this example is the same as or smaller than that of the cylindrical joints 8A to 8C. 7, the wall fixing tool 14 is not visible, and reference numeral 37 in FIG.

  Thereby, when the constituent material of each lattice element unit 4 is resin, for example, when the resin contracts due to heat in summer, the thermal contraction is applied to the latching portion 15 of the wall fixture 14 and the lattice element unit 4 side. It becomes possible to absorb at the sliding latching portion with the latched portion 16. As a result, it is possible to prevent the lattice element unit 4 from being deformed due to heat shrinkage, and to eliminate the need for measures for preventing water leakage due to deformation and to adjust the unevenness with the wall surface 10 (FIG. 1). It can last for a long time.

  Next, the watering means 18 connected to the rainwater outlet 12 will be described.

  FIG. 3 shows an example of the case where the grid 1 having the rainwater storage function is installed on the front wall 10a and the side wall 10b of the house, respectively, and between the rainwater outlet 12 of the grid 1 and the watering hose 18a. A filtration unit 25 is interposed. As shown in FIGS. 3 (b) and 4, the filtration unit 25 of this example is formed in a flat box shape, and a rainwater intake 26 for taking in rainwater provided at the upper end of the filtration unit 25 is connected to rainwater via a hose 27. The outlet 12 is connected and connected.

  As shown in FIG. 9A, the internal space of the filtration unit 25 is partitioned up and down by a filter portion 28, and a rainwater intake pipe 30 that is opened and closed by a water stop valve 31 is accommodated on the upper side. The rainwater from 26 diffuses and flows down to the entire upper surface of the filter portion 28 via the rainwater intake pipe 30. Rainwater filtered by the filter unit 28 is stored in the lower water storage unit 32 via a plurality of water conduits 29. A rainwater discharge port 33 is provided at the bottom of the water storage section 32, and a watering hose 18a (FIG. 4) having a shower discharge port 34 at the tip is connected to the rainwater discharge port 33 from the outside.

  In this example, the upper end position P1 of the water storage section 32 in the filtration unit 25 is positioned lower than the height (FIG. 4) of the rainwater outlet 12 of the water storage unit 4A, and the filtration unit 25 is moved to the wall surface 10 ( Fix to Fig. 3). Thereby, watering from the watering hose 18a can be performed using the water pressure in the water reservoir 9 (FIG. 2). In other words, water can be sprayed to the outside by using water pressure without using a power source such as a pump.

  The filtration unit 25 is fixed using the wall surface fixture 14 shown in FIG. Each wall fixture 14 is formed of a substantially J-shaped bracket that is fixed to the wall surface 10 (FIG. 3) using a fastener 35 such as a nail. Thus, the hooked portion 16 on the back surface of the filtration unit 25 is hooked.

  Thus, in addition to the function of connecting the rainwater outlet 12 and the watering hose 18a, the filtration unit 25 of this example has a filter function of removing dust and impurities such as dead leaves, dust, and sand in rainwater. Therefore, it can be used for various purposes as domestic water or emergency water. Further, when cleaning the filter portion 28, the water stop valve 31 is closed so that no water pressure is applied, and then a scattering prevention and insect repellent cover (not shown) covering the upper surface opening of the filtration unit 25 is removed, The collected garbage can be cleaned. Furthermore, by making the filtration unit 25 into a flat box shape, forward protrusion is suppressed, and, like the lattice 1, it does not stick out to the road side or obstruct traffic.

  Further, the filtration unit 25 of the present example is a flat box shape whose outer shape is easily deformed, but the hooked portion 16 on the back surface is hooked and slidable on the hooking portion 15 of the wall fixture 14. Therefore, there is an advantage that the deformation of the filtration unit 25 can be absorbed by the slide latching portion, and the appearance deterioration due to the deformation can be suppressed as much as possible.

  FIG. 8 shows the grids 1 and 1 having the rainwater storage function of the present example on the front wall 10a (FIG. 3 (a)) and the side wall 10b (FIG. 3 (b)) across the corner 10c of the building. In the case of installation, an example in which both grids 1 and 1 are connected to each other using a corner tubular joint 8D is shown.

  The corner tubular joint 8D includes the second tubular joint 8B of the water storage unit 4A closest to the corner portion 10c side of the front wall 10a and the first cylinder of the water storage unit 4A closest to the corner portion 10c of the side wall 10b. The cylindrical joint 8A is connected to each other via a cylindrical connecting body 5 protruding from the second cylindrical joint 8B. The water reservoir 9 (FIG. 2) in the lattice 1 on the front wall 10a side and the water reservoir 9 (FIG. 2) in the lattice 1 on the side wall 10b side communicate with each other through the corner tubular joint 8D. Thus, the amount of rainwater stored increases, and only one rainwater inlet 11, rainwater outlet 12, and overflow outlet 17 are provided. Further, only the cylindrical connecting body 5 of the corner cylindrical joint 8D is exposed at the connection portion between the two grids 1 and 1, and the appearance of the corner portion 10c is not impaired. The corner tubular joint 8D may be fixed to the wall surface 10 but may not be fixed. In this case, the hooked portion 16 (FIG. 7) provided on the back surface can be omitted.

  FIG. 10 shows an example in which the lattice element unit 4 is used as the horizontal lattice 3 and the cylindrical connector 5 is used as the vertical lattice 2. In this example, the uppermost lattice element unit 4 among the lattice element units 4 horizontally arranged in the upper and lower four rows is made to function as an overflow unit 4B, and the lower three-stage lattice element units 4 are respectively water storage units. It functions as 4A.

  One tubular body 6 of the uppermost overflow unit 4B is provided with a rainwater inlet 11 that opens upward, and a first tubular joint 8A that is located on both the left and right sides of the tubular body 6 including the rainwater inlet 11. The cylindrical connection body 5 protruding to the lower surface side of (FIG. 5B) is connected to the lateral connection port 20 of the second cylindrical joint 8B (FIG. 5C) of the lower water storage unit 4A. . Each water storage unit 4A is formed with a water storage portion that is closed at both ends and extends in the lateral direction B. Rainwater flowing from the rainwater inlet 11 is stored in the water storage unit 4A. It is like that.
