It is held by a floor side rail 9 mounted on the top. The ceiling-side rail 8 includes a long flat plate-like attachment portion 8a and guide pieces 8b and 8b extending downward from both ends in the short direction of the attachment portion 8a and parallel to each other. The upper edge of the partition W is held between 8b and 8b. The floor-side rail 9 includes a long flat plate-like attachment portion 9a, and guide pieces 9b and 9b that extend upward from both ends in the short direction of the attachment portion 9a and are parallel to each other. The lower end edge of the partition W is held between 9b and 9b.

  The mounting bracket 1 is attached to the frame 3 of the system ceiling C, that is, the support bar 2, and as shown in FIG. 1, the supported portion 11 supported by the support bar 2 and the partition mounting attachment portion. 12.

  As shown in FIG. 2A, the supported portion 11 is formed in a cross shape having four arm portions 11a projecting in a cross direction from a substantially central portion corresponding to the cross-shaped hole A, Can be inserted into the support bar 2 from the cross-shaped hole A (that is, the inside surrounded by the mounting portion 21, both side pieces 22, 22 and both support portions 23, 23). . Further, the arm portion 11a is chamfered on both sides so as to be tapered and includes tapered surfaces 11b and 11c. The tapered surfaces 11b and 11c are inclined at an angle of 45 degrees with respect to the protruding direction of the arm portion 11a. Is set to have.

  As shown in FIG. 2 (b), the mounting portion 12 is composed of a bolt portion 12a suspended from a substantially central portion on the lower surface side of the supported portion 11, and a nut portion 12b that can be screwed to the bolt portion 12a. Has been. The nut portion 12b has a washer portion 12c on the upper surface side, and the width dimension (length dimension of the diameter) of the washer portion 12c is set wider than the width dimension of the opening 24 of the support bar 2. . The attachment portion 12 is also used as a grip portion when attaching the attachment fitting 1 to the support bar 2. In FIG. 2B, the bolt portion 12a is shown with a simplified shape.

  The mounting bracket 1 is configured as described above. Next, a method for mounting the mounting bracket 1 to the system ceiling C will be described with reference to FIGS.

  First, as shown in FIG. 3A, the supported portion 11 of the mounting bracket 1 is supported in the support bar 2 from the cross-shaped hole A of the portion P where the above-mentioned support bar 2 is connected in a cross shape. Insert from below the bar 2. Next, as shown in FIG. 3B, it is rotated 45 degrees around the vertical direction (state shown by a dotted line in FIG. 3B). Thereafter, when the mounting bracket 1 is slid along the opening 24 to a desired mounting position, the one arm portions 11a and 11a and the other arm portions 11a and 11a are respectively supported by the both support portions of the support bar 2. 23, the supported portion 11 is supported by the support bar 2 in a form (shown by a solid line in FIG. 3 (b)) placed on the support bar 2, thereby attaching the mounting bracket 1 to the support bar 2. Can do.

  At this time, by rotating the mounting bracket 1 by 45 degrees as described above, the tapered surfaces 11b and 11c inclined by 45 degrees with respect to the protruding direction of the arm portions 11a are formed in the vertical direction (FIG. 3B). The state shown by the solid line in FIG. 3B is substantially parallel to the inner surfaces of the two side pieces 22 and 22 of the support bar 2 in the vertical direction and the support bar 2 in the horizontal direction (left and right direction in FIG. 3B). Therefore, for example, even when the arm portion 11a hits the side pieces 22 and 22 of the support bar 2 when the mounting bracket 1 is slid laterally along the opening 24, the taper surface 11c The arm portion 11a can be prevented from being caught on the side pieces 22 and 22, and thus can be moved smoothly in the support bar 2. The same applies to the case of sliding in the vertical direction. In this case, each arm portion 11a is prevented from being caught by the tapered surface 11b and can be moved smoothly.

  Then, after the mounting bracket 1 is moved to a desired position, the nut portion 12b of the mounting portion 12 is tightened, and as shown in FIG. If the support portions 23 are sandwiched, the mounting bracket 1 is firmly attached to the support bar 2. When the mounting portion 12 is tightened, the bolt portion 12a naturally rotates in the rotation direction of the nut portion 12b, and as a result, the supported portion 11 attempts to rotate in the rotation direction of the nut portion 12b. Therefore, the length is such that the arm portion 11a of the supported portion 11 comes into contact with the inner surfaces of both side pieces 22 and 22 of the support bar 2 when inserted into the support bar 2 and rotated by a predetermined angle about the vertical direction. If the dimensions are set, as shown in FIG. 3 (c), the arm portion 11 comes into contact with the inner surfaces of the two side pieces 22, 22 of the support bar 2. It is possible to prevent the nut portion 12b from being screwed securely. In addition, by further increasing the number of portions on the inner surfaces of the side pieces 22 and 22 by the tapered surfaces 11b and 11c of the arm portion 11a, further prevention of idling is achieved.

  As described above, the mounting bracket 1 is attached to the system ceiling C, and the ceiling-side rail 8 for mounting the partition W is attached to the system ceiling C using these mounting brackets 1. That is, the ceiling-side rail 8 is tightened by inserting the bolt portion 12a of the mounting bracket 1 through a bolt hole (not shown) formed in the attachment portion 8a and screwing the nut portion 12b from below the attachment portion 8. As shown in FIG. 4B, the attachment portion 8a is sandwiched between the supported portion 11 and the washer portion 12c of the nut portion 12b together with the support portions 23 and 23 of the support bar 2 as shown in FIG. Is firmly attached to the system ceiling C.

  In this way, the above-described ceiling-side rail 8 is attached to the system ceiling C by using the mounting bracket 1, and the floor-side rail 9 is made to overlap the ceiling-side rail 8 in the vertical direction as shown in FIG. By attaching to the partition, the partition W can be attached by the ceiling side rail 8 and the floor side rail 9.

  Therefore, according to the mounting bracket 1 of the present invention, the supported bar 11 is provided with the supported portion 11 having a shape corresponding to the cross-shaped hole A opened at the portion P where the support bar 2 is connected in a cross shape. By inserting the supported portion 11 into the support bar 2 from below the support bar 2 through the hole A, the mounting bracket 1 can be attached to the system ceiling C. Therefore, even after the system ceiling C is installed, Since it is not necessary to remove the ceiling plate 7 attached, the mounting bracket 1 can be easily attached to the system ceiling C, so that the workability is improved, and as a result, the partition W can be easily attached to the system ceiling C. Will be able to. In addition, if the arm portion 11a protruding in the cross direction from the supported portion 11 serves as a retaining portion of the supported portion 11 if it is slid along the opening portion 24 after being inserted into the support bar 2, the opening portion 24 is prevented. Thus, the mounting bracket 1 can be reliably prevented from falling off, and even if a downward force is applied to the mounting bracket 1, it does not come out. In addition, by inserting the fitting 1 into the support bar 2 and rotating it 45 degrees around the vertical direction, for example, only one arm portion 11a and the other arm portion 11a are provided on both sides of the support bar 2. Rather than being placed on the support portions 23 and 23, all four of the one arm portions 11 a and 11 a and the other arm portions 11 a and 11 a are all on the support portions 23 and 23 of the support bar 2. Therefore, it is possible to increase the overlapping portions of the supported portion 11 and both the support portions 23 and 23, and in addition, the arm portions 11a are formed with tapered surfaces 11b and 11c. Thereby, the overlap part of both the support parts 23 and 23 and the arm part 11a can further be increased.
