JPH10115113A - Earthquake-proof support bracket for steel tower type vertical circulation type parking-device support in building - Google Patents

Abstract

PROBLEM TO BE SOLVED: To maintain the strength of a steel tower type vertical circulation type parking-device support in a building, and to improve an earthquake-proof effect by installing an earthquake- proof support bracket having a vibration-proof rubber at a front end to the support and mounting the vibration-proof rubber under the state, in which the vibration-proof rubber is faced oppositely to a column or a beam for the building through a required clearance. SOLUTION: Earthquake-proof support brackets 12 are projected and set up towards beams 5 for a building near to each support 3. Vibration-proof rubbers 9 are stuck at the front ends of the earthquake-proof support brackets 12, and the surfaces of the vibration-proof rubbers 9 and the surfaces of the beams 5 for the building are faced oppositely through required clearances. Since the earthquake-proof support brackets 12 are installed to the supports 3 constituting a steel tower 11, the earthquake-proof support brackets 12 are assembled automatically and construction cost is reduced when the steel tower 11 is built up. Since the parking-device support is not slipped off easily even when large force is applied and large horizontal force applied to the steel tower 11 is transmitted to the building, large earthquake-proof force works from the building to the steel tower 11 as reaction, and a required earthquake-proof effect can be obtained.

Cars are moved in and out of the vehicle by changing directions using a turntable p provided in front of the entrance. Here, q indicates an intermediate stay, r indicates a control panel base, and s indicates slack take-up for removing the slack of the chain c.

When such a vertical circulation type parking device is installed in a building, if the parking device is directly supported by the pillars or beams of the building, vibrations generated by the parking device are transmitted to the building, and there is a possibility that livability may be impaired. is there. For this purpose, an independent steel tower is erected in the building, thereby supporting the parking device and preventing vibration from being transmitted to the building. FIG. 5 is a plan view of such a steel tower type vertical circulation parking device in a building. In the figure, 1 is a parking space in a building, 2 is a vertical circulation type parking device, 3 is a column constituting four corners of a steel tower, 4 is a column of a building, 5
Is a building beam, and 6 is a turntable provided on the front of the parking device.

[0004] It is not economically feasible to construct a tower installed in a building into an earthquake-resistant structure similar to a tower of a parking device installed independently outside. Therefore, when an earthquake occurs, there is a possibility that the column itself will be largely shaken. Therefore, the column 3 is held through a required gap by the anti-seismic support bracket attached to the beam 5 or the column 4 of the building, so that the column is largely shaken. Is done. The clearance is provided to prevent the shaking during normal operation from being transmitted to the building. The anti-seismic support bracket is 6
They are provided at intervals of about m.

FIGS. 6A and 6B show an example of such an anti-vibration support bracket, wherein FIG. 6A shows an L-shape and FIG. 6B shows a box-shaped example. In these figures, reference numeral 3 denotes a column made of H-shaped steel. 5
Is a building beam, and 7 is an L-shaped bracket. The L-shaped bracket is attached to a beam 5 of the building by an anchor bolt 8. An anti-vibration rubber 9 is affixed to the surface of the L-shaped bracket 7 facing the column 3, and a required gap is provided between the anti-vibration rubber 9 and the column 3. Reference numeral 3a denotes a steel plate attached to a portion of the column 3 facing the anti-seismic rubber 9. The box-shaped bracket 10 is provided so as to surround the column 3. In this case, anti-vibration rubber 9 is attached to the inner surfaces of the three sides.

[0006]

The above-described seismic support brackets 7, 10 have the following problems. (1) When an earthquake occurs, a large tensile force and a shearing force are simultaneously applied to the anchor bolts 8 fixing the seismic proof support brackets 7 and 10 due to the swing of the columns 3, so that the anchor bolts 8 are cut and the horizontal force is reduced. Therefore, the purpose of the anti-seismic support brackets 7 and 10 cannot be achieved. (2) After the building is put into operation, the seismic support bracket 7 is attached to the building frame.
Installation costs are increased due to centering, installation of internal scaffolding, mounting of brackets, etc. for mounting 10.

The present invention has been devised in view of the above-mentioned problems of the prior art. By attaching an anti-seismic support bracket to a column, it has sufficient strength and has a low construction cost. It is an object of the present invention to provide an anti-seismic support bracket for a circulating parking device support.

[0008]

In order to achieve the above object, an anti-seismic support bracket for a tower-type vertical circulation type parking device support in a building according to the present invention is provided by a tower having columns installed upright at four corners of a parking space in a building. An anti-seismic support bracket for the column of the tower-type vertical circulation type parking device for supporting a circulation type parking device, wherein the bracket has an anti-seismic rubber at its tip and is provided so as to project from the column to a pillar or a beam of the building. The anti-seismic rubber and the pillars or beams of the building face each other with a required gap.

It is preferable to provide a gap adjusting means for adjusting the gap between the earthquake-proof rubber and the pillar or beam of the building.

It is preferable that the main body of the anti-vibration support bracket is made of a square steel pipe because it is lightweight and has sufficient strength.

Next, the operation of the present invention will be described. According to the present invention, the seismic support bracket is automatically assembled when the steel tower is assembled, because the seismic support bracket is attached to the pillar that forms the tower, not the pillar or beam of the building. Therefore, the construction cost is reduced and the horizontal force can be safely transmitted to the building when an earthquake occurs because there are no weak parts such as anchor bolts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a steel tower in a building having the earthquake-proof support bracket of the present invention. FIG. 2 is a view taken in the direction of arrows AA in FIG. FIG. 3 is a plan view of an anti-seismic support bracket having a gap adjusting means. In these drawings, the same parts as those described as the conventional example are denoted by the same reference numerals, and duplicate description will be omitted. In these figures, reference numeral 11 denotes a steel tower that supports the parking device 2 (see FIG. 5), and has columns 3 at four corners. The four columns are connected to each other via beams 14 assembled in a girder to form an independent tower 11. The beams 14 are provided at a plurality of locations at a required interval in the height direction.

Reference numeral 12 denotes an anti-seismic support bracket, which is shown in FIGS.
As shown in FIG. 2, a total of eight pieces are provided so as to project two at a right angle from each column 3 toward the beam 5 of the nearest building from one place in the height direction. An anti-vibration rubber 9 is affixed to the tip of the anti-vibration support bracket 12, and the surface of the anti-vibration rubber 9 and the surface of the beam 5 of the building face each other via a required gap. The gap between the surface of the anti-vibration rubber 9 and the surface of the beam 5 of the building is preferably 10 to 20 mm. Bracket 12
May be provided every other floor in the height direction. That is, they are provided at intervals of about 6 m.

FIG. 3 shows the details of the seismic isolation support bracket 12. The main body 12a of the anti-seismic support bracket 12 has a structure in which flanges 12b are welded to both ends of a rectangular steel pipe, and a base end thereof is fastened to the column 3 by a bolt nut 13. 12
c is a gap adjusting means having an anti-vibration rubber 9 attached to one surface,
Four bolts 12d on the opposite surface where the anti-seismic rubber 9 is attached
Is erected by welding. Bolt 12d to body 12a
The drilled holes are inserted through the flanges 12b on the tip side, and the two nuts 12e screwed to the bolts 12d tighten the flanges 12b to fix the positions.

Next, the operation of the present embodiment will be described. The anti-seismic support bracket 12 is not attached to the pillar 4 or the beam 5 of the building as in the prior art, but is attached to the column 3 constituting the tower 11. Therefore, when the tower 11 is assembled, the anti-seismic support bracket 12 is automatically assembled. Will rise. Accordingly, construction costs are reduced. In addition, since it is not fixed to the pillars 4 and the beams 5 of the building with the anchor bolts 8 unlike the conventional seismic support brackets 7 and 10, even if a large force is applied, it does not come off easily. Since the large horizontal force applied to the building is transmitted to the building, a large seismic force acts on the steel tower 11 from the building as a reaction, and the necessary seismic effect is obtained.

Since the length of the seismic support bracket 12 can be adjusted by the gap adjusting means 12c, the gap can be adjusted according to the unevenness of the finishing surface of the beam 5 of the building. Since the bracket body 12a is made of square steel pipe,
It is lightweight and has a structure that can sufficiently withstand the compressive force.

The present invention is not limited to the embodiments described above, and various changes can be made without departing from the gist of the invention. For example, in this embodiment, the anti-seismic support bracket 12 has been described to transmit the horizontal force to the beam 5 of the building, but may be one that transmits the horizontal force to the pillar 4 of the building.

[0018]

As described above, the anti-seismic support bracket of the present invention has the following excellent effects because it is directly attached to the column constituting the steel tower. (1) No centering for mounting the bracket and no internal scaffolding are required, and mounting work costs are extremely low.

(2) The horizontal force acting on the tower during an earthquake can be transmitted to the building without difficulty, and the seismic effect is large.
