[Industrial applications]

 The present invention relates to a multilevel parking facility.

[0002]

[Prior Art]

 In the multi-level parking facility, a mechanical parking device that accommodates a large number of vehicles in a vertically movable manner is installed in the parking tower in which a flat outer wall plate is supported by a steel frame structure standing on the ground. Is generally known as being supported and provided by the. FIG. 6 shows the structure of the parking tower 65. That is, the outer wall plate 68 of the parking tower 65 is rigidly connected to the beam 70 of the steel structure 69 that supports the mechanical parking device. 7 and 8 specifically show an example of a support structure for the outer wall plate 68, and the outer wall plate 68 is coupled to the beam 70 via a vertical furring strip 71 and a bracket 72.

In such a three-dimensional parking facility, when the mechanical parking device is operated, this serves as a vibration source, and the parking tower 65 vibrates in its own vibration mode as shown in FIG. The outer wall plate of the parking tower 65 may act like the diaphragm of the speaker to give low-frequency sound or low-frequency vibration to the surrounding houses.

On the other hand, there is a proposal to attach a vibration damping device to a mechanical parking device inside the parking tower for damping the vibration. For example, Japanese Utility Model Laid-Open No. 59-48962 discloses a proposal of suspending and supporting a support base of a parking device on a parking tower, and Japanese Utility Model Publication No. 62-71435 and Japanese Utility Model Publication No. 63-201237. Discloses a proposal to attach damping means to the pedestal of the parking device.

[0005]

[Problems to be solved by the device]

 However, although each of the above proposals has a certain effect in that the vibration of the mechanical parking device is prevented from being transmitted to the steel frame structure, it is actually difficult to effectively suppress such vibration transmission. The problem of vibration of the outer wall plate still remains, and the internal structure of the parking tower becomes complicated. Therefore, in the present invention, it is intended to suppress the vibration transmission from the steel frame structure to the outer wall plate.

[0006]

[Means for Solving the Problems]

 In order to solve such a problem, the present invention, as shown in FIG. 6, causes both the beam and the outer wall plate of the steel frame structure to flex in the same vibration mode as the mechanical parking device operates, and as a result, In view of generation of low frequency sound and low frequency vibration, the outer wall plate does not follow the vibration of the steel frame structure.

That is, the means for solving the above-mentioned problems is a machine for accommodating a large number of vehicles in a vertically movable manner in a parking tower in which a flat outer wall plate is attached to a steel frame structure erected on the ground. The parking structure is a multi-level parking facility supported by the steel frame structure, wherein the outer wall plate is connected to the steel frame structure at both side edges thereof in a state in which a tensile force is applied in the horizontal direction. The intermediate portion of the outer wall plate in the horizontal direction is movably supported by the steel frame structure in a direction perpendicular to the plate surface of the outer wall plate.

In this case, between the intermediate portion of the outer wall plate and the steel frame structure, the vibration damping means for damping the vibration in the direction perpendicular to the plate surface of the outer wall plate facing the steel frame structure is provided. This is a more suitable means for solving the above problems.

[0009]

[Action]

 In the above multi-level parking facility, since the middle part of the outer wall plate is movable in the direction perpendicular to the plate surface with respect to the steel frame structure, even if the steel frame structure vibrates due to the operation of the mechanical parking device, The intermediate portion does not mechanically follow the steel frame structure and vibrate. Further, since a horizontal tensile force is applied to the outer wall plate, it is difficult to resonate with the steel structure.

Further, when the vibration damping means is further provided, the vibration of the outer wall plate can be effectively suppressed.

[0011]

[Effect of the device]

 Therefore, according to the present invention, the steel frame structure supporting the mechanical parking device is connected to both side edges of the outer wall plate in a state in which a horizontal tensile force is applied to the outer wall plate, and the horizontal wall of the outer wall plate is connected. Since the middle part in the vertical direction is movably supported in the direction perpendicular to the plate surface, vibration of the outer wall plate due to vibration of the steel frame structure is suppressed, and low-frequency sound and low-frequency vibration are prevented from affecting the parking tower area. can do.

Further, according to the device having the vibration damping means, vibration and noise can be suppressed more effectively.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. -Overall configuration-The overall configuration of the multilevel parking facility 1 is shown in FIG. In the figure, 2 is a steel frame structure that supports the mechanical parking device 4, and 3 is an exterior material attached to the steel frame structure 2. As shown in FIG. 2, the steel frame structure 2 includes four pillars 5, beams 6 vertically arranged at intervals and connecting adjacent columns 5 and 5, and a diagonal member 7. The parking device 4 supports a large number of cages 12 for accommodating and mounting a vehicle W in a circulating manner by an endless chain 11 wound around upper and lower sprockets 10 and 10. Is driven to rotate by a drive motor (not shown). The exterior material 3 includes a ceiling plate 15 and an outer wall plate 16.

-Mounting Structure of Outer Wall Plate to Steel Structure-The outer wall plate 16 has a flat plate shape, and as shown in FIG. 3, both side edge portions have tension adjusting means on columns 5 and 5 of the steel structure 2, respectively. The intermediate portion in the horizontal direction is connected to the beam 6 of the steel structure 2 by the intermediate supporting means 18, 18 and the vibration damping means 19.

-Tension Adjusting Means- The tension adjusting means 17 is specifically shown in FIG. First, the top of a horizontal section T-shaped support member 21 is fixed to the pillar 5, and a through hole is formed in the leg of the support member 21. The tension adjusting means 17 applies a tensile force in the horizontal direction to the outer wall plate 16 by supporting the leg portions of the supporting member 21. A bolt 23 that horizontally protrudes outward from the side end surface of the outer wall plate 16 from the mounting bracket 22 and is inserted into a leg through hole of the support member 21, and a tightening nut 24 and a lock nut that are screwed into the bolt 23. 25 and.

That is, the outer wall plate 16 is given a predetermined tensile force in the horizontal direction by tightening the tightening nuts 24 of the tension adjusting means 17, 17 provided on both side edges of the outer wall plate 16, and the outer wall plate 16 is locked in that state. It is connected to the pillar 5 via the support member 21 by tightening the nut 25.

—Intermediate Support Means— The intermediate support means 18 is specifically shown in FIG. 5, and the intermediate portion of the outer wall plate 16 in the horizontal direction is movable with respect to the beam 6 in a direction perpendicular to the plate surface. And a supporting member 32 fixed to the inner surface of the outer wall plate 16 and a supporting member 32 fixed to the beam 6.

The receiving member 31 has a peripheral edge portion fixed to the outer wall plate 16, a receiving portion 31a protruding toward the beam 6 in the central portion, and a through hole 31b formed in the receiving portion 31a. .. The support member 32 includes a head 35 provided inside the receiving portion 31a, and a shaft portion (screw portion) protruding toward the beam 6 through the through hole 31b of the receiving member 31; It is provided with both inner and outer nuts 33, 34 for fixing the shaft portion of the bolt 35 to the beam 6.

In this case, the through hole 31b of the receiving portion 31a is formed smaller than the outer diameter of the outer nut 34 and the bolt head portion 36. As a result, the outer wall plate 16 allows relative displacement in the direction perpendicular to the plate surface with respect to the beam 6 by the distance between the outer nut 34 and the bolt head 36, and the outer nut 34 and the bolt. The head portion 36 functions as a stopper that restricts excessive displacement of the outer wall plate 16.

—Vibration Damping Unit— The vibration damping unit 19 includes a cylinder having two chambers partitioned by a piston, and a damper formed by enclosing a fluid capable of moving the two chambers in the cylinder. The cylinder is fixed to the beam 6, and the piston rod is fixed to the outer wall plate 16. The damping characteristic of the vibration damping means 19 is set so that the damping force becomes the highest at the natural frequency of the outer wall plate 16.

-Effects-Thus, in the case of the above-described multi-level parking facility 1, even if the steel frame structure 2 vibrates and the beam 6 bends in the horizontal direction due to its own weight due to the operation of the parking device 4, the amount of deflection is the same. If the relative displacement between the outer wall plate 16 and the outer wall plate 16 is within the range, no displacement occurs in the intermediate portion of the outer wall plate 16. That is, the bending of the beam 6 does not directly cause the outer wall plate 16 to vibrate.

Further, the vibration of the steel frame structure 2 is transmitted to the outer wall plate 16 through the pillar 5, but since a horizontal tensile force is applied to the outer wall plate 16, it is Resonance is prevented. Particularly, in the case of this embodiment, since the horizontal tensile force of the outer wall plate 16 can be adjusted, the natural frequency of the outer wall plate 16 is set so as not to resonate with the natural frequency of the steel structure 2. Easy to do. Further, when the outer wall plate 16 vibrates with respect to the steel structure 2, the vibration is suppressed by the action of the vibration damping means 19, and in particular, the outer wall board 16 resonates at the natural frequency with the external vibration. Effectively prevented by 19.

When an excessive external force acts on the outer wall plate 16 due to an earthquake or a strong wind, the outer nut 34 or the bolt head 36 of the supporting member 32 fixed to the beam 6 receives the receiving portion of the receiving member 31 on the outer wall plate 16 side. The outer wall plate 16 is prevented from excessively displacing by abutting against 31a. That is, since the excessive external force can be received by the steel frame structure 2, the outer wall plate 16 is prevented from being damaged.

As shown in FIGS. 7 and 8, when the vertical furring strip 71 and the bracket 72 are provided between the outer wall plate and the beam, the outer wall plate and the vertical furring strip are provided between the outer wall plate and the vertical furring strip. The intermediate support means 18 and the vibration damping means 19 may be provided between the bracket and the bracket.

When the outer wall plate itself has a low tensile strength, a steel strip may be fixed to the outer wall plate to apply a tensile force to the steel strip.
