[Means for Solving the Problems]

 The hanging bolt fixture according to the present invention has a box body having an open surface as a surface embedded in a structure, a pair of support rails installed in parallel between opposite side plates of the box body, and a space between the pair of support rails. A pair of upper and lower movable mounting members formed so as to sandwich the support rail in the erection direction so as to be sandwiched from above and below, and a suspension bolt is formed through the pair of movable mounting members so that the longitudinal position can be adjusted. And a pair of nuts screwed to the hanging bolt so that the pair of movable mounting members can be clamped from above and below.

[0006]

[Action]

 In this invention, a pair of nuts are screwed into the oblong holes of the pair of movable mounting members that are passed between the pair of support rails of the hanging bolt mounting member so that the hanging bolts can be caught. The box body that is sandwiched and embedded in the structure suspends the suspension bolt through the support rail, the movable mounting member, and the nut without any problem of pulling strength. When the movable mounting member is screwed by the nut, the movable mounting member is positionally adjustable in the erection direction of the support rail, and the suspension bolt is screwed in the elongated hole of the movable mounting member so as to be longitudinally positionally adjustable. Therefore, by adjusting and screwing the positions in both directions, the suspension bolt can be fixed at an arbitrary position within a plane within the position adjustment range in both directions.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1A and 1B show a suspension bolt attachment according to an embodiment of the present invention. FIG. 1A is an overall front view of a suspended state, FIG. 1B is a bottom view, and FIG. 1C is a side sectional view. In FIG. 1, 3 is a suspension bolt, and as shown in FIG. 1 (A), this suspension bolt fixture 1 is embedded in a ceiling or the like of a concrete structure 9 and attached to the suspension bolt fixture 1. The hanging bolt 3 is used to suspend a suspended object such as the duct 5 via the support member 4. As shown in FIGS. 1 (B) and 1 (C), this hanging bolt attachment 1 is a box body 11 made of steel plate and the like, one side of which is open and the other five sides are closed, and a box body 11 Anchors 18 such as steel rods are attached to the back of the box by welding, etc., and are installed in parallel inside the box 11 between the opposite side plates of the box 11 by welding etc. on both side plates. Two support rails 12 and 13, two upper and lower movable mounting members 14 and 15 formed so as to sandwich the support rails 12 and 13 from above and below by passing over the support rails 12 and 13, and this movable mounting member 14 , 15 are provided with elongated holes 14h and 15h formed in the longitudinal direction through which the hanging bolt 3 passes, and nuts 16 and 17 screwed to the hanging bolt 3.

As shown in FIG. 2 (A), first, as shown in FIG. 2 (A), the method of embedding the hanging bolt fixture 1 in the concrete structure 9 is as follows. Attach the setting frame 6 by hitting it with a nail or the like. Next, as shown in FIG. 2 (B), the hanging bolt fixture 1 is fitted into the setting frame 6 and installed. Next, as shown in FIG. 2 (C), concrete is poured. After the concrete is solidified, the concrete form 7 and the setting frame 6 are removed as shown in FIG. 2 (D). When the concrete is solidified, the concrete is attached to the anchors 18 and the like, and the suspension bolt fixture 1 is firmly embedded, so that there is no problem such as pull-out strength. After the concrete has solidified, the hanging bolt 3 can be attached to the hanging bolt fixture 1 as described later. If the decorative panel 2 is attached with the attaching screw 21 so that the inside cannot be seen, a better appearance can be obtained.

Next, the mounting procedure and function of the suspension bolt 3 will be described. As described above with reference to FIG. 2, the box body 11 of the hanging bolt fixture 1 is embedded at a predetermined position in the concrete structure 9. However, since it is concrete pouring work, it is impossible to set the position of the box body 11 accurately. After the concrete has solidified, as shown in FIGS. 1 (B) and 1 (C), the movable mounting member 14 is passed over the support rails 12 and 13, and the movable mounting member 15 is superposed and supported from below. The rails 12 and 13 are sandwiched, and the hanging bolt 3 to which the nut 17 is screwed is inserted through the elongated holes 15h and 14h of the movable mounting members 15 and 14, and the nut 16 is screwed into the tip of the hanging bolt 3. Before strongly tightening the movable mounting members 14 and 15 with the nuts 16 and 17, move the movable mounting members 14 and 15 in the installation direction of the support rails 12 and 13 (vertical direction in FIG. 1B) to determine the position, By moving the suspension bolt 3 in the elongated holes 14h and 15h of the movable mounting members 14 and 15 in the horizontal direction in FIGS. 1B and 1C to determine the position, the movable mounting members 14 and 15 can be moved. The position of the hanging bolt 3 can be freely adjusted and determined within a plane limited by the range and the movable range of the hanging bolt 3 in the elongated holes 14h and 15h. If the movable mounting members 14 and 15 are tightened with the nuts 16 and 17 after the position of the suspension bolt 3 is adjusted and set, the movable mounting members 14 and 15 pinch the support rails 12 and 13, and the movable mounting members 14 and 15 are clamped. , 15 and the position of the suspension bolt 3 with respect to the movable mounting members 14, 15 are also fixed, so that the position of the suspension bolt 3 is fixed at the adjustment setting position.

Since the hanging bolt fixture 1 has a wide range of position adjustment of the hanging bolt 3, when the hanging bolt fixture 1 is embedded in the concrete structure 9, the setting frame 6 shown in FIG. It is not necessary to install the box body 11 directly on the concrete formwork 7 while restraining it by using the reinforcing bar 8 or the like. Since the hanging bolt fixture 1 has no portion projecting from the surface of the concrete structure 9, it has a good appearance, but as shown in FIG. 2 (D), if the decorative panel 2 is attached, the appearance will be further improved. You can
