  Hereinafter, a characteristic configuration of the horseshoe mounting bracket 10 will be described.

  In FIG. 1, reference numeral 22 denotes a claw formed inward from the inner peripheral surface of the bolt insertion hole 11 and having an appropriate interval. The claw 22 has a function of catching the screw thread of the bolt 4 during construction, thereby preventing the bolt 4 from dropping.

  As shown in FIG. 2, at the time of construction, the upper end surface 9 a of the nut 9 screwed to the bolt 4 hits the peripheral lower surface portion b ′ of the bolt insertion hole 11 in the flat lower surface b of the plate-like base 12. In this embodiment, an angle is given to the portion of the horseshoe mounting bracket that the nut 9 that presses (tightens) the horseshoe mounting bracket 10 hits. That is, the flat lower surface b (the peripheral lower surface portion b ′ of the bolt insertion hole 11 on the lower surface b) of the plate-like base portion 12 with which the nut 9 contacts is parallel to the faucet mounting portion lower surface L and the plate-shaped arm portion 13. Out of the upper portion 30 (the right plate-like arm portion 13 in FIG. 2), the lower end portion b of the peripheral edge of the bolt insertion hole 11 so that the front end side upper portion 30b abuts the faucet mounting portion lower surface L instead of the rear end side upper portion 30a. 'And a tip side upper portion 30b of the upper portion 30 of the plate-like arm portion 13 are provided in a crossing direction. In this embodiment, as shown in FIG. 1 (C), the lower end b ′ of the plate-like base portion 12 against which the nut 9 abuts and the upper tip side of the upper portion 30 of the plate-like arm portion 13 against the faucet attachment portion lower surface L. The angle θ formed by the upper surface d ′ of the upper portion 30b, that is, the angle θ formed by the straight line r and the straight line t is set to 4 degrees, and 4 ≦ θ ≦ 10 degrees is preferable. In this embodiment, the upper surface d 'is the upper surface d of the upper portion 30 of the plate-like arm portion 13 including the rear end side upper portion 30a. In FIG. 1C, a straight line r indicated by a one-dot chain line is an extension line from the upper surface d (d ′), and a straight line t indicated by a dotted line is an extension line from the lower surface b (b ′). is there. q is an intersection of the straight line r and the straight line t.

  Thus, as shown in FIG. 4, the release paper on the lower surface of the seat packing 40 that has been applied to the lower surface M of the hot-water mixing tap main body 1 is peeled off, and the pipe joints 6, 7 and bolts already connected to the hot-water mixing tap main body 1. 4 is inserted into the through-hole 8 so that the seat packing 40 does not deviate from the center of the through-hole 8 and the hot and cold water mixing plug main body 1 is positioned on the upper surface H of the mounting portion 5. Further, the mounting packing 50 is positioned between the horseshoe mounting bracket 10 and the lower surface L of the mounting portion. In this state, the bolt 4 is inserted into the bolt insertion hole 11 of the horseshoe mounting bracket 10 and the pipe joints 6 and 7 are inserted between the left and right arm portions 13 and 13 of the horseshoe mounting bracket 10. Subsequently, the nut 9 is tightened. At this time, the flat lower surface b ′ (b) of the plate-like base portion 12 against which the nut 9 is contacted is positioned in parallel with the attachment portion lower surface L, so that the upper ends 30 and 30 of the plate-like arm portions 13 and 13 are on the tip side. The upper surface d ′ of 30b, 30b can be brought into contact with the lower surface L of the faucet mounting portion. Then, by tightening the nut 9 in this state, it is possible to increase the degree of the tightening force on the front side of the hot and cold water mixing plug main body 1 where the tightening force of the nut 9 has been weak. In addition, it is possible to reliably prevent the front side of the hot and cold water mixing plug body 1 from rising from the upper surface of the faucet mounting portion. Further, by providing the plate-like arm portion 13 with the recess 23 having an opening on the upper side, the upper portion 30 functions as a strength reinforcing rib, and the plate-like arm portion 13 is stronger than the case where the recess 23 is not provided. Can be strong.

  In the state where the faucet is attached to the faucet attachment portion, the peripheral lower surface b ′ of the bolt insertion hole 11 is parallel to the attachment portion lower surface L, and in this embodiment, the upper portion 30 of the plate-like arm portion 13 The upper portion 30 of the plate-like arm portion 13 is configured to have a flat upper surface d so that the tip-side upper portion 30b contacts the faucet mounting portion lower surface L by surface contact. The upper portion 30 of the arm 13 may be configured. Moreover, as a structure of the upper part 30 of the plate-shaped arm part 13, the shape of the location contact | abutted to the faucet attachment part lower surface L may be provided with uneven | corrugated shape.

  FIG. 5 shows another embodiment of a horseshoe mounting bracket according to the present invention. 5, the same reference numerals as those shown in FIGS. 1 to 4 are the same or equivalent. In the horseshoe-shaped mounting bracket 10 shown in FIG. 1, the left and right plate-like arm portions 13 are strengthened in strength by providing the recesses 23, 23 only in the left and right plate-like arm portions 13, 13. The horseshoe-shaped mounting bracket 51 is composed of the plate-like base portion 12, the inclined portions 20, 21 and the left and right plate-like arm portions 13, 13, and one side from the left and right end portions (inclined portions 20, 21) of the plate-like base portion 12. The extension lengths of the left and right plate-like arm portions 13, 13 are shorter than those of the horseshoe-type mounting bracket 10. Further, the horseshoe-shaped mounting bracket 51 is formed with a single horseshoe-shaped recess 53 that is open in the entire upper side thereof. 54 and 54 are a pair of front and rear outward flanges formed so as to be connected to the upper portions 30 and 30 of the left and right plate-like arm portions 13 and 13, respectively. That is, the horseshoe-shaped mounting bracket 51 is provided with the upper portions 30 and 30 that function as ribs and the outward flanges 54 and 54 along the outer peripheral edge of the recess 53. Compared with the case where it is not provided, the strength of the entire horseshoe mounting bracket 51 can be increased.
