  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a brace and an attaching method thereof according to the present invention will be described with reference to the drawings. First, a description will be given of the brace, and then a method for attaching the brace will be described. In each embodiment, the same components are denoted by the same reference numerals, and different configurations are denoted by different symbols. To explain.

  FIG. 1 shows a brace 1 according to the first embodiment. The brace 1 is provided with an oblique brace 3 that is a brace material between suspension bolts 2 suspended at an appropriate interval on the lower surface of the slab, and is attached to the cylinder 4 and the cylinder 4 so as to be rotatable. And four diagonal anti-vibration members 3. The diagonal anti-vibration material 3 is a long bolt, and one end thereof is screwed into a rotating plate 6 provided on the mounting piece 5 on the outer peripheral surface of the cylindrical body 4.

  The rotating plate 6 is formed by bending a single plate into a plane triangle, and the tip end portion that is folded into two is attached to the mounting piece 5 with a pin 7. Therefore, the diagonal anti-vibration material 3 rotates around the rotating plate 6. As described above, when the slant anti-vibration member 3 is not used in the same manner as an umbrella, the slant anti-vibration member 3 is in a state of hanging downward, that is, in a closed state, and when used, it is rotated and opened.

  On the other hand, the fixed piece 8 is attached to the other end portion of the diagonal anti-vibration material 3. To attach this to the adjacent suspension bolt 9, it is once removed from the oblique anti-vibration material 3 and attached to the suspension bolt 9. Later, the other end of the diagonal anti-vibration material 3 is screwed into the nut 10 of the fixed piece 8. As shown in FIG. 2, the through hole 11 into which the suspension bolt 9 is inserted in the fixed piece 8 is cut at the center, and the cut plate 12 is bent in opposite directions. A female screw 13 that engages with the bolt 9 is formed.

  Further, as shown in FIG. 3, the cylindrical body 4 includes an insertion hole 14 into which the suspension bolt 2 is inserted, and a storage portion 15 having a lower side wide and a narrow upper side is formed in an inner lower portion of the insertion hole 14. . Then, four gripping members (or three) 16 as fixing means are stored in the storage portion 15, and these gripping members 16 are always pushed up by a spring 18 provided between the bottom plate 17. When the four gripping members 16 are combined, the shape is the same as that of the storage portion 15, that is, the lower side is wide and the upper side is narrowed, and a suspension bolt insertion portion 19 is formed at the center. 9 is formed.

  Accordingly, when the gripping member 16 is pushed up by the spring 18, the tube 4 is contracted inward to narrow the insertion portion 19, while when it is lowered, the insertion portion 19 is expanded outward to enlarge the insertion portion 19. Can be pushed up, but cannot be pushed down. This is because when the cylinder 4 is pushed up, the gripping member 16 is lowered to enlarge the insertion portion 19, while when the cylinder 4 is pushed down, the gripping member 16 is raised to narrow the insertion portion 19.

  FIG. 4 shows a brace 21 according to the second embodiment. This brace 21 is different from the brace 1 of the first embodiment only in the rotating plate 23, and the other configuration is the same. The rotating plate 23 has an L shape in which a reinforcing plate 24 is welded to the bottom side. One of the rotating plates 23 is connected to the fixed piece 8 by a pin 25, and the oblique bent antistatic material 3 is screwed into the other bent piece 26. .

  FIG. 5 shows a brace 22 according to the third embodiment. The brace 22 of (1) is different from the brace 1 of the first embodiment only in the fixed piece 27, and the other configuration is the same. The fixing piece 27 includes a horizontal piece 28 fixed horizontally to the suspension bolt 9 and a swash plate 29 connecting the oblique anti-vibration member 3. The oblique anti-vibration member 3 is attached to the bent piece 30 of the swash plate 29 with a nut. 31 is connected. The fixing piece 27 is easily fixed to the suspension bolt 9. Further, in the anti-vibration tool 22 of (2), the penetration hole 11 is formed with the notch plate 12 in the same manner as the anti-vibration tool 1 of the first embodiment so that the fixing piece 27 can be fixed horizontally to the suspension bolt 9. It is bent in opposite directions, and a female screw 13 is formed here.

  Next, the attachment method of a brace is demonstrated based on FIG. 6 and FIG. This attachment method uses the brace 1 of the first embodiment. This is to install the brace 1 on the suspension bolt 2 having a length of 1500 mm or more suspended from the lower surface 32 of the slab at an interval of about 900 mm.

  First, as shown to (1) of the figure, the operator 34 attaches the cylinder 4 to the one suspension bolt 2 from the scaffold 33 for ceilings. This is because when the suspension bolt 2 is inserted into the insertion hole 14 of the cylindrical body 4 and the cylindrical body 4 is pushed up along the suspension bolt 2, the gripping material 16 is lowered and the insertion portion 19 is expanded. Pushed up. And when it pushes up until it reaches the uppermost part of the suspension bolt 2, that is, the slab lower surface 32, the cylinder 4 cannot be lowered by the gripping material 16 (because the gripping member 16 is contracted by the downward pressing force and the insertion portion 19 is narrowed). .

  Next, as shown in (2) of the figure, the fixing piece 8 is attached to the suspension bolt 9 adjacent in the XY direction of the suspension bolt 2 in which the cylinder 4 is inserted. This is the one that is attached to the suspension bolt 9 after removing the other attached to the other end of the diagonal anti-vibration material 3, and the four other anti-vibration materials 3 are opened like an umbrella and the other end The part is connected to the fixed piece 8. As shown in FIG. 2, the diagonal anti-vibration material 3, which is a long bolt, is screwed into the nut 10 of the fixed piece 8, and the length is adjusted by the rotation of the diagonal anti-vibration material 3.

  Next, as shown in (3) of the figure, when the horizontal anti-vibration material 35 is attached in the vertical and horizontal directions to the lower end of the oblique anti-vibration material 3, that is, the place where the fixed piece 8 is attached, this horizontal anti-vibration material As shown in FIG. 7, 35 is attached in a cross shape around the suspension bolt 2 into which the cylindrical body 4 is inserted. It should be noted that the cleats 21 and 22 of the second and third embodiments are also attached by the same method.
