  The large pull support 5 is a wall that contacts the large pull side surface, and may further include a wall that extends substantially perpendicular to the large pull receiving portion 51.

  The shaft portion 7 passes through the inside of the turnbuckle 1, the base contact portion 3, and the large pull support portion 5. The shaft portion 7 is not fixed to any of the turnbuckle 1, the base contact portion 3, and the large pull support portion 5, and is movable with respect to the turn buckle 1, the base contact portion 3, and the large pull support portion 5. It is preferable that The shaft portion 7 is formed with a male screw as a whole, for example. A lower end 7b of the shaft portion 7 is embedded in the base. A large pull fixing portion 9 is provided at the upper end 7 a of the shaft portion 7.

  The large pull fixing portion 9 is provided at the upper end 7 a of the shaft portion 7, and fixes the large pull by sandwiching the large pull together with the large pull support portion 5. This pinching force is a vertical force in FIG. The large pull fixing portion 9 is made of a nut, for example, and is fitted into the male screw portion (an example of the first male screw portion) at the upper end 7a of the shaft portion 7 from above by a screw action. In order to increase the area of the portion where force is applied to the large pull, the large pull fixing portion 9 may have a larger area at the lower end than at the upper end.

  The male thread portion of the shaft portion 7 is for fitting the large pull fixing portion 9 by a screw action when the large pull fixing portion 9 is made of a nut. In the present embodiment, in order to facilitate the processing of the shaft portion 7, the shaft portion 7 is formed of a dimensioned bolt, and a male screw portion is formed on the entire shaft portion 7. When the large pull fixing portion 9 is made of something other than a nut, the shaft portion 7 does not have to be formed with a male screw portion. Even when the large pull fixing portion 9 is made of a nut, at least the shaft portion 7 is not provided. It is only necessary that a male screw portion is formed on the upper end 7a.

  Each of the upper part and the lower part of the turnbuckle 1 may be provided with nuts 11a and 11b for preventing the turnbuckle 1 from rotating. Further, washers (spring washers) 13a and 13b may be provided between the turnbuckle 1 and each of the nuts 11a and 11b.

The wheel anchor 15 may be fixed to the lower portion 7b of the shaft portion 7 by other methods such as adhesion.

  FIG. 3 is a bottom view showing the configuration of the base contact portion.

  With reference to FIG. 3, in the base contact portion 3, the base plate 31 is formed with a plurality of holes 3 a through which screws for fixing the bundle 100 to the base are passed. A hole 3b constituting a hollow portion is formed in the central portion of the base plate 31. The hole 3b and its periphery are recessed upward.

  FIG. 4 is a top view showing the configuration of the large pull support portion.

  With reference to FIG. 4, in the large pull support portion 5, the large pull receiving portion 51 and the rubber sheet 53 are formed with a plurality of holes 5 a through which screws for fixing the large pull are passed. A hole 5b constituting a hollow portion is formed at the center of the large receiving portion 51. The shaft portion 7 passes through the hole 5b. The hole 5b and the periphery thereof are recessed downward, and a rubber sheet 53 is attached to a portion excluding these portions.

  Next, a method for fixing the fork on the base using a bundle will be described with reference to FIGS.

  Referring to FIG. 5, first, on the base BS made of concrete, for example, a position where the bundle 100 is to be installed is determined, and a hole is made at that position. Next, the wheel anchor 15 is inserted into the hole. Thereby, the wheel anchor 15 is fixed in the base BS.

  Referring to FIG. 6, the bundle 100 is then mounted on the wheel anchor 15 by fitting the lower end 7 b of the shaft portion 7 to the wheel anchor 15. At this time, the large pull fixing portion 9 is removed from the shaft portion 7. The base plate 31 contacts the upper surface of the base BS by its own weight. The base plate 31 may be fixed to the base BS with screws (not shown). Subsequently, the nuts 11a and 11b are loosened so that the turnbuckle 1 can be rotated.

  Referring to FIG. 7, next, the height of the contact surface with the large drawing in the large drawing support portion 5 (here, the length from the upper surface of the base BS to the upper surface of the rubber sheet 53) is provided. Adjust to the planned height L1. The height of the contact surface of the large pull support portion 5 with the large pull can be adjusted by rotating the turnbuckle 1. That is, when the turnbuckle 1 is rotated in the direction indicated by the arrow AR1, the base contact portion 3 and the large pull support portion 5 are loosened (moved in a direction away from the turnbuckle 1), and the large pull support portion 5 The height of the contact surface with the large pull increases. On the other hand, when the turnbuckle 1 is rotated in the direction indicated by the arrow AR2, the base contact portion 3 and the large pull support portion 5 are tightened (moved in a direction approaching the turnbuckle 1). The height of the contact surface with the large pull becomes low.

  Referring to FIG. 8, next, the nuts 11 a and 11 b are tightened, and the rotation of the turnbuckle 1 is fixed so that the height of the contact surface of the large pull support portion 5 with the large pull does not change. Subsequently, a large pull WD made of wood in which the hole PL is formed in advance is prepared, and the large pull WD is arranged on the large pull support 5 so that the shaft portion 7 is inserted into the hole PL. By inserting the shaft portion 7 into the hole PL, the large pull WD can be disposed on the large pull support portion 5 more stably. At this time, the large pull WD may be further fixed to the large pull support 5 with screws. Thereafter, the large pull fixing portion 9 is fitted into the shaft portion 7 and the large pull WD is tightened by the large pull fixing portion 9 from above. Accordingly, the large pull WD is sandwiched between the large pull support portion 5 and the large pull fixing portion 9. In this state, the height of the contact surface of the large pull fixing portion 9 with the large pull (here, the length from the upper surface of the base BS to the lower surface of the large pull fixing portion 9) is the height L1 and the large pull WD. This corresponds to the height L2 of the sum with the thickness d1.

  Through the above steps, the large pull WD is fixed on the base BS.

  Subsequently, a method of adjusting the bundle when the large drawing becomes thin with time and the thickness of the large drawing in the vertical direction is reduced will be described with reference to FIGS.

  Referring to FIG. 9, here, it is assumed that the large pull WD is thinned over time, and the vertical thickness of the large pull WD is changed from the thickness d1 (FIG. 8) to the thickness d2 (d1> d2). . In this case, a gap exists between the large pull support portion 5 and the large pull WD, or between the large pull fixing portion 9 and the large pull WD. As a result, the force that sandwiches the large pull WD between the large pull support portion 5 and the large pull fixing portion 9 is weakened, and rattling occurs in the large pull WD.

  Referring to FIG. 10, in the case of FIG. 9, the nuts 11a and 11b are loosened so that the turnbuckle 1 can be rotated. Next, the turnbuckle 1 is rotated in the direction indicated by the arrow AR1. As a result, the large pull support portion 5 is raised, the gap between the large pull support portion 5 and the large pull fixing portion 9 is narrowed, and the large pull WD can be sandwiched again between the large pull support portion 5 and the large pull fixing portion 9. it can.

  In addition, the height of the contact surface with the large pull in the large pull fixing portion 9 is maintained at the height L2. The height of the contact surface with the large drawing in the large drawing fixing part 9 defines the height of the upper surface of the large drawing from the base BS and the height of the floor base, and these heights change with time. It is not a thing.

  Referring to FIG. 11, finally, nuts 11 a and 11 b are tightened, and rotation of turnbuckle 1 is fixed so that the height of the contact surface with large pull in large pull support 5 does not change. In this state, the height of the contact surface of the large pull support portion 5 with the large pull corresponds to the height L3 of the difference between the height L2 and the thickness d2.

  The adjustment of the bundle 100 is completed by the above steps.

[Effect of the embodiment]
According to the present embodiment, even when the overdrawing thins over time, the overdrawing can be sandwiched between the overdrawing support portion and the overdrawing fixing portion by raising the overdrawing support portion. As a result, it is possible to suppress large-scale rattling. In addition, since the large support portion can be raised by rotating the turnbuckle, the height of the large support portion can be easily adjusted. Further, by allowing the shaft portion to penetrate the large pull, the large pull can be more stably fixed on the large pull support portion.

  Moreover, the height of the large pull fixing portion can be easily adjusted by configuring the large pull fixing portion with a nut and fitting it into the male screw portion of the shaft portion by a screw action.

  Further, by providing the wheel anchor at the lower portion of the shaft portion, the bundle can be more stably fixed to the base.

  Furthermore, the length of the portion embedded in the base in the shaft portion (depth of the hole formed in the base) by enabling the shaft portion to move inside the turnbuckle, the base contact portion, and the large support portion Regardless, the base contact portion can be easily brought into contact with the upper surface of the base.
