[Brief description of the drawings]

[0014] [Figure 1] FIG. 1 is a schematic diagram of a wall surface fixing frame used for fixing an article such as a rainwater tank to a wall surface according to one embodiment of the present invention. [Diagram 2] FIG. 2 is a photograph showing a structure for fixing a rainwater tank to a wall surface according to one embodiment of the present invention. [Diagram 3] FIG. 3 is an external view showing a state in which a rainwater tank according to one embodiment of the present invention is fixed to a wall surface fixing frame. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A structure for fixing an article such as a rainwater tank to a wall surface and a wall surface fixing frame used in the fixing structure according to one embodiment of the present invention (hereinafter referred to as "this embodiment") will be described with reference to FIG.

[0016] In the article fixing structure of this embodiment, a wall fixing frame 1 for fixing an article to a wall surface of a building is divided into four parts, left, right, top and bottom, and the two parts 2 and 3 on the left and right sides are fixed to the wall surface. The lower part 4 is formed into a frame shape and has both left and right ends 4b and 4d connected to the bottom ends 2b and 3d of the two parts 2 and 3 on the left and right sides, respectively, for placing the article on it, and the upper part 5 has both left and right ends 5a and 5c connected to the top ends 2a and 3c of the two parts 2 and 3 on the left and right sides, respectively, to support the back of the article.

[0017] In the article fixing structure according to this embodiment, an article can be installed and fixed using only the hollow wall surface as a fulcrum, without contacting the bottom of the building or the ground, by using the wall fixing frame 1. That is, by fixing the two parts 2 and 3 on the left and right sides of the wall fixing frame 1, which fix the article to the hollow wall surface, to the hollow wall surface, the article can be firmly fixed to the hollow wall surface.

[0018] In this embodiment, the item is preferably a rainwater tank. By installing a rainwater tank on the wall of a building, especially on the hollow wall mentioned above, the height can be freely determined, and when installed at a high place, water can be transported to the place of use by using potential energy without using electricity.

[0019] As shown in Figure 2, the rainwater tank is preferably rectangular, and more preferably a thin rectangular parallelepiped. By making it a thin rectangular parallelepiped, it becomes easier to fix it to the wall of a building using a wall fixing frame 1.

[0020] The lower part 4 formed in a frame shape of the wall mounting frame 1 is preferably formed in a U-shape to correspond to the rectangular shape of the rainwater tank. A rectangular (rectangular) rainwater tank can be placed on the lower part 4 formed in a U-shape.

[0021] The two parts 2 and 3 on both the left and right sides of the wall mounting frame 1 are preferably fixed to the wall of the building with screws 10. As shown in FIG. 1, it is more preferable to fix the part 2 on the right side with multiple screws 10 arranged in a zigzag pattern from the top end 2a to the bottom end 2b. By arranging multiple screws 10 in a zigzag pattern as described above, the load can be distributed and strength can be increased. The number of screws 10 is preferably five or more, and from the viewpoint of workability, it is preferable to limit the number to seven. The part 3 on the left side can also be fixed in the same way with screws 10.

[0022] As shown in FIG. 1, the right side of the lower part 4 of the wall mounting frame 1 is U-shaped. Side end Department 4b is connected to the lower end 2b of the right part 2, and the left end of the lower part 4 is formed into a U-shape. Side end Department Connect 4d to the bottom end 3d of the left part 3. The L-shaped connection between the right part 2 and the lower part 4 is made by a reinforcing member 6. Side end Department It is preferable to connect the lower end 2b of the right part 2 to the lower end 2b of the right part 2 with three screws 11. It is more preferable to increase the strength by connecting the three screws 11 in a non-linear manner. Side end Department 1, 4b and the reinforcing member 6 are connected by six rivets 13. The L-shaped connection between the left part 3 and the lower part 4 is also connected to the lower part 4 via the reinforcing member 6. On the left end Department 4d is preferably connected to the lower end 3d of the right part 2 by three screws 11.

[0023] 1, the back of the article can be supported by connecting the right end 5a of the upper part 5 of the wall mounting frame 1 to the upper end 2a of the right part 2 and the left end 5c of the upper part 5 to the upper end 3c of the left part 3. The connections are preferably made with screws 12.

[0024] Fig. 3 shows an external view of the rainwater tank according to this embodiment fixed to a wall mounting frame. It is preferable to provide a fastener on the upper part 5 to be attached to the top surface of the rainwater tank, and to fix the rainwater tank with the fastener.

[0025] (Wall mounting frame material) The material of the wall mounting frame is preferably steel plated (to impart corrosion resistance), and among them, stainless steel is more preferable from the viewpoint of strength.

[0026] (Handling items of different sizes) In order to accommodate items such as rainwater tanks of different sizes, multiple types of parts for the left and right sides, lower parts, and upper parts that make up the wall-mounted frame can be prepared, so that the appropriate part can be selected depending on the size of the rainwater tank, etc.

[0027] (Verification of fixed frame and screw load) For the wall mounting frame shown in Figure 1, the frame and screw loads were verified as follows. (a) The total tank weight was set at 1,300N (tank body + fixed frame + parts), and it was confirmed that the frame structure and screws were capable of withstanding a load of more than three times Unwin's safety factor (3,900N or more). (b) The load was changed from 1300N to 2600N to 3900N to etc. from above, below and on the side, and the condition of the fixing frame and screws was checked. (c) The number of screws fixing the frame to the wall was reduced from 7 on each side, to 6 on each side, with no screws on top, to 6 on each side, with no screws on the bottom, to 5 on each side, with no screws on the top or bottom, and we checked to see if the number was consistent with the calculated values. (d) The number of fixing screws and rivets at the connecting part of the L-shaped portion was reduced to two and two, respectively. (e) Because there was a risk of damage to the drinking water supply pipe due to deflection, the amount of deflection at both ends of the fixed frame was measured.

[0028] Neither the fixing frame nor the screws were damaged up to 3,900N (safety factor 3). For the fixed frame, the deflection rate increased above 3900N, and at 6400N the load could no longer be applied, so testing was discontinued. When we checked the frame, we found that the L-shaped part was torn, so we considered ways to reinforce it. The number of fixing screws in the L-shaped part was increased from two to three, and the installation was done in an L-shape to increase strength. Strength was increased by increasing the number of rivets from two in one row to three in each of two rows, top and bottom. We re-tested the fixed frame and found no problems with the 6400N. There were no problems with the screws, even at the calculated value of 6400N.

[0029] (Verification results) The measurement results of the deflection (displacement) are shown in Table 1.
