FIGS. 1 and 2 are perspective views showing a first water heater fixing hardware, FIG. 3 is a perspective view showing a pressing portion, and FIG. The perspective view which shows a 2nd water heater fixed metal fitting, FIG. 5 is explanatory drawing which shows the function of a press part, FIG. 6 is explanatory drawing which shows the attachment state of a water heater leg part.

First, the 1st water heater fixed metal fitting S1 which concerns on this embodiment is demonstrated using FIG. 1 thru | or FIG.
FIG. 2 is a perspective view of FIG. 1 viewed from the back side, and shows the internal structure of the first water heater fixing hardware S1.
Note that the water heater fixing hardware S is a superordinate concept, and, as will be described later, the first water heater fixing hardware S1 and the second water heater fixing hardware S2 are derived by the difference in the penetration direction of the adjusting bolt 3.
As shown in FIGS. 1 and 2, the water heater fixing hardware S <b> 1 according to this embodiment includes a main body 1, a pressing portion 2 (see FIG. 2), and an adjustment bolt 3.

The main body 1 according to this embodiment includes side portions 11 and 11, a top surface portion 12, a front surface portion 13, fixing pieces 14 and 14, and locking ribs 15 and 15.
The side surface portion 11 according to the present embodiment is a substantially pentagonal plate, and has two sides with different lengths rising substantially vertically from both ends of the longest side 11a (the long side is the “rising long side 11b”, and the short side is Is denoted as “rising short side 11c”), the upper side 11d extending from the upper end of the rising long side 11b substantially parallel to the longest side 11a and extending toward the short side 11c (the upper side 11d extends to a substantially central portion of the longest side 11a). , Extending substantially parallel to the longest side 11a), a front end of the upper side (the end opposite to the side in contact with the rising long side 11b) and a main body oblique side 11e that bridges the rising short side 11c.

Further, the front side (the rising short side 11c side) from the substantially central portion of the longest side 11a is cut out into a substantially rectangular shape, and a “cutout portion K” is formed.
The height of the notch K is configured to be slightly larger than the thickness of the lower end plate P1 constituting the leg of the water heater, and the lower end plate P1 can be inserted into the notch K. Yes.
The side surface parts 11 and 11 are arranged to face each other substantially in parallel so that the longest side 11a faces downward and the shapes are matched.

Further, the top surface portion 12 according to the present embodiment is a slope formed so as to bridge between the main body oblique sides 11e, 11e constituting the opposite side surface portions 11, 11, and the front surface portion 13 is the top surface portion. It hangs down so that it may be flush with the rising short sides 11c, 11c opposite to each other from the lower end side.
The front surface portion 13 is formed with a body portion adjusting bolt through hole 13a.
The main body adjustment bolt through hole 13a is formed as a loose hole having a long axis in the vertical direction.
Therefore, the top surface portion 12 becomes an inclined surface that descends from the rear to the front (rises from the front to the rear).

The fixing piece 14 according to the present embodiment is a substantially rectangular plate-like body that is bent outward so as to be substantially perpendicular to the side surface portion 11, and is formed with a fixing hole 14a.
Note that the fixed piece 14 is bent outward from the longest side 11a of the side surface portion 11 from the end where the rising long side 11b rises to the position where it is aligned with the contact position of the upper side 11d and the oblique side 11e. Is formed.
Moreover, the fixing pieces 14 and 14 are respectively formed in the side parts 11 and 11 which oppose each other.

Further, the locking rib 15 according to the present embodiment is substantially directed from the front side edge (the edge on the side where the front surface portion 13 is formed) of the fixed piece 14 upward (to the side where the upper side 11d is disposed). It is a substantially rectangular plate that stands vertically.
The locking ribs 15 are formed on the fixing pieces 14 formed on the opposing surfaces 11, 11, respectively.

Since the top surface portion 12 constituting the main body portion 1 is a slope that descends from the rear to the front (the front surface portion 13 side), the side surface portions 11, 11, the top surface portion 12, and the front surface portion 13 form the main body portion. The outer shape of the front of 1 is a wedge shape.
In the present embodiment, the distance between the uppermost portion of the top surface portion 12 (the wedge-shaped topmost portion: the rear side) and the lower end portion of the main body portion 1 is larger than the height of the leg portion P of the water heater. It is configured.
Although this will be described later when the installation method is described, it is to add a function as a wedge to the first water heater fixing hardware S1 and to fix the leg portion P securely.

As shown in FIGS. 2 and 3, the pressing portion 2 according to the present embodiment includes pressing portion side walls 21 and 21 and a pressing portion front wall 22.
The pressing portion side wall 21 is a substantially trapezoidal plate body with one corner formed substantially at a right angle.
The two pressing portion side walls 21, 21 are disposed to face each other in parallel so that the hypotenuses on the side sandwiching the substantially right-angled corners face downward so that the shapes are matched (that is, they face each other). The upper base and the lower base are arranged so as to stand up and down substantially in parallel).

The two pressing portion side walls 21 and 21 are opposed to each other with an interval slightly smaller than the interval in which the side surface portions 11 and 11 constituting the main body portion 1 are opposed to each other.
That is, the pressing portion 2 is configured to be housed inside the main body portion 1.

Also, the pressing portion front wall 22 of a substantially rectangular plate is formed so as to bridge the upper bases of the pressing portion side walls 21 and 21 facing each other (the shorter side of the substantially parallel opposing sides). Yes.
The pressing portion front wall 22 has a pressing portion adjusting bolt screw hole 22a.
The inner wall surface of the press adjusting bolt through hole 22a is threaded, and the adjusting bolt 3 is screwed.

It should be noted that the inclination of the hypotenuse (the hypotenuse that is not the leg on the side sandwiching the substantially right angle corner) disposed on the upper side is aligned with the inclination of the hypotenuse 11e that constitutes the side part 11. It is configured.
Hereinafter, this hypotenuse that constitutes the pressing portion side wall 21 is referred to as a “pressing portion side hypotenuse 21a”.
Further, the leg side that sandwiches the substantially right-angled corner constituting the pressing portion side wall 21 is referred to as a “pressing fixing portion 21b”.
In addition, the boundary corner | angular part of the press fixing | fixed part 21b and the press part front wall 22 is notched in the substantially triangular shape.
In this way, the slope extending from the pressing portion fixing portion 21b that is notched to the pressing portion front wall 22 so as to be continuous is hereinafter referred to as “auxiliary slope 21c”.
When the pressing portion 2 rides on the lower end plate P1, the pressing portion 2 rides from the pressing portion front wall 22 side. Then, the pressing portion 2 climbs on the lower end plate P1 along the auxiliary inclined surface 21c and rises, and the pressing portion-side oblique side 21a comes into pressure contact with the inner wall surface of the top surface portion 12 of the main body portion 1.
Therefore, the pressing part 2 can more reliably press and fix the lower end plate P1.
As described above, the auxiliary inclined surface 21c functions to smoothly ride on the lower end plate P1 of the pressing portion 2 and allows the pressing portion 2 to be pushed up to enable more reliable pressing and fixing.

  The adjusting bolt 3 according to the present embodiment is a known bolt, and is inserted into the front surface portion 13 and the pressing portion front wall 22 via a washer or the like so as to be rotatable.

As shown in FIG. 2, the pressing portion 2 is assembled to the main body portion 1.
The pressing portion 2 has its pressing portion side oblique sides 21a, 21a aligned and in contact with the inner wall surface of the top surface portion 12 that bridges both the main portion oblique sides 11e, 11e constituting the main body portion 1, and the pressing portion front wall 22 is The main body 1 is inserted into the main body 1 so as to be aligned with the front surface 13 constituting the main body 1 on the inside (so as to face substantially parallel).

  At this time, the pressing portion adjusting bolt screwing hole 22a formed in the pressing portion front wall 22 and the main body portion adjusting bolt through hole 13a formed in the front wall 13 are configured to communicate with each other. The adjusting bolt 3 is passed through a communicating hole between the screw hole 22a and the main body adjusting bolt through hole 13a via a washer, a nut, and the like, and the pressing portion 2 is assembled to the main body 1 by the adjusting bolt 3.

In the first water heater fixing hardware S1, the adjustment bolt 3 is fixed with the head facing outward.
That is, the adjustment bolt 3 can be rotated from the outside of the main body 1.
As will be described later, in the present embodiment, since the adjustment bolt 3 does not change its horizontal position, the rotation of the adjustment bolt 3 causes the pressing portion 2 screwed to the adjustment bolt 3 to be drawn toward the front surface portion 13 side. They are separated (that is, the pressing part 2 moves in the horizontal direction).

Moreover, since the top surface part 12 which comprises the main-body part 1 at this time becomes a slope which descends toward the front (front surface part 13 arrangement | positioning side) from back, when the press part 2 is pulled toward the front surface part 13, The pressing part 2 will descend along the slope of the top surface part 12.
Therefore, the lower part can be pressed and fixed at the lower end side (press fixing part 21b) of the pressing part 2.

Moreover, in FIG. 4, 2nd water heater fixed metal fitting S2 is shown.
The second water heater fixing hardware S2 has the same structure as the first water heater fixing hardware S1 in the main body 1 and the pressing part 2, but the insertion direction of the adjusting bolt 3 is different.
Since the other configuration is the same as that of the first water heater fixed hardware S1, description thereof is omitted.
That is, in the second water heater fixing hardware S <b> 2, the adjustment bolt 3 is fixed so that the head is disposed inside the main body 1.
Therefore, in 2nd water heater fixed metal fitting S2, adjustment bolt 3 will be constituted so that fastening and relaxation can be performed from the inside of main part 1.

Next, the function of the pressing portion 2 will be described with reference to FIG.
5 is a cross-sectional view taken along line AA in FIG.
Since the functions of the pressing portion 2 of the first water heater fixed hardware S1 and the second water heater fixed metal S2 are the same, the first water heater fixed hardware S1 will be described.
As shown in FIG. 5A, the pressing portion 2 is assembled inside the main body portion 1, but when the adjustment bolt 3 is rotated in the direction to be fastened in this state, the adjustment bolt 3 moves in the horizontal direction. Therefore, the pressing portion 2 screwed with the adjusting bolt 3 is pulled in the X direction by the pressing portion adjusting bolt screwing hole 22a.

  As described above, the pressing portion 2 moves along the inner wall surface of the top surface portion 12 because it is in contact with the inner wall surface of the top surface portion 12 that bridges the oblique sides 11e and 11e of the main body portion 1 constituting the main body portion 1. It will be.

At this time, the top surface portion 12 that bridges both the oblique portions 11e and 11e of the main body portion is inclined so as to descend toward the front surface portion 13 in the same manner as the inclination of the oblique portions 11e and 11e of the main body portion. The partial side walls 21, 21 are lowered with movement.
Therefore, as shown in FIG. 5B, the pressing fixing portions 21 b and 21 b that are the lower end sides of the pressing portion side walls 21 and 21 protrude downward from the main body portion 1 as the movement proceeds.
That is, it is possible to press the lower side with the protruding pressing fixing portions 21b and 21b.

With reference to FIG. 6, a method of fixing the leg P of the water heater by the first water heater fixing metal S1 and the second water heater fixing metal S2 thus configured will be described.
As the leg portion P of the water heater, as long as it is a leg having a configuration in which a substantially flat plate body (a configuration corresponding to the lower end plate P1) is fixed in contact with the installation surface, it does not depart from the spirit of the present invention. Any shape may be used, but in the present embodiment, a rectangular shape is used as the leg portion P of the water heater.
First, the first water heater fixing hardware S1 is attached to the floor surface.
This is performed by installing the first water heater fixing metal S1 at a predetermined position and bolting from the fixing holes 14a, 14a formed in the fixing pieces 14,14.

Next, the lower end plate P1 constituting the leg-shaped leg P is slid from the side surface and fitted into the notch K.
Next, by rotating the adjustment bolt 3 of the first water heater fixing metal S1 in the fastening direction, the pressing portion 2 is moved in the direction of the front surface portion 13, and the lower end plate P1 is pressed and fixed by the pressing fixing portions 21b and 21b.

At this time, since the top surface portion 12 constituting the main body portion 1 is an inclined surface, the front outer shape of the main body portion 1 is wedge-shaped by the side surface portions 11, 11, the top surface portion 12, and the front surface portion 13. Yes.
In the present embodiment, the distance between the uppermost part of the top surface part 12 (the wedge-shaped uppermost part) and the lower end part of the main body part 1 is the height of the leg part P of the water heater, that is, the lower end plate P1 and the upper end part. It is comprised so that it may become larger than the distance with board P2 (or water heater bottom face).

Therefore, the front of the main body 1 surely enters between the lower end plate P1 and the upper end plate P2 (or the bottom surface of the water heater) and serves as a wedge.
Therefore, the front of the main body 1 is securely fitted between the lower end plate P1 and the upper end plate P2 (or the water heater bottom surface) constituting the leg portion P, and the lower end plate P1 is reliably pressed and fixed.
Note that the distance between the uppermost portion of the top surface portion 12 (the wedge-shaped uppermost portion) and the lower end portion of the main body portion 1 is the height of the leg portion P of the water heater, that is, the lower end plate P1 and the upper end plate P2 (or the water heater). Even if the distance is smaller than the distance to the bottom surface), the lower end plate P1 is securely fixed by the first water heater fixing hardware S1 by the above configuration.

Next, the lower end plate P1 is further fixed by the second water heater fixing hardware S2.
