Description

  The present invention relates to a method for remodeling an existing two-multi-stage parking apparatus having a plurality of pallets, and a parking facility remodeled by this method.

The two- and multi-stage parking apparatus is a mechanical parking apparatus in which pallets for loading a vehicle are arranged in two or more stages in the vertical direction.
Such a two-multistage parking apparatus is disclosed in, for example, Patent Documents 1 and 2.

The existing two- and multi-stage parking apparatus may be requested to be disassembled partly or entirely and used for other purposes as the size of the vehicle increases and the demand is sluggish.
In order to satisfy this demand, for example, Patent Documents 3 and 4 have been proposed.

The “planar parking facility” of Patent Document 3 installs a pillar on the bottom surface of a pit, installs a beam along either the length direction or the width direction, and fixes the end of the beam to the side surface of the pit. , Install the deck on the beam.
In the “planar parking lot” of Patent Document 4, a floor board is laid on the upper end of the pit, and the top of the floor board is used as a parking space. The floor board is laid on a large beam and a small beam installed on the upper end portion of the pit, and a column is interposed between the bottom surface of the pit and the large beam.

The two- and multi-stage parking apparatus has a pit having a depth of one stage or more for vehicle parking. The pit depth for one vehicle is about 1.7 to 2.0 m, and the pit depth for two vehicles is about twice that.
In addition, the bottom of the pit of the two- and multi-stage parking apparatus can support a large vertical load because it supports the total weight of the parking apparatus, but the side surface of the pit may be damaged when a large horizontal load is applied.

In the devices disclosed in Patent Documents 3 and 4, when the pit upper surface is used as a parking space for a vehicle, a horizontal force proportional to the vehicle weight acts on the pit upper portion when the vehicle enters and exits or during an earthquake during parking.
When this horizontal force is applied, in the devices of Patent Documents 3 and 4, there is a possibility that the beam supporting the deck portion (or floor plate) will be greatly displaced horizontally, and the beam end portion may collide with the pit side surface and damage the pit side surface. was there.
Further, in order to support this horizontal force, when the beam end is fixed to the pit side surface, it is necessary to reinforce the pit side surface, which may require excessive cost and time for the reinforcement work.

  The present invention has been developed to solve the above-described problems. That is, the object of the present invention is to dismantle part or all of the existing two- and multi-stage parking device and effectively use the pit, and it is not necessary to reinforce the side of the pit, and horizontal force is generated in the event of an earthquake. The object is to provide a method for remodeling a two- and multi-stage parking apparatus that can prevent damage to the side surface of the pit even if it acts, and a parking facility remodeled by this method.

According to the present invention, there are provided a plurality of basic parking units having a pit below the loading / unloading height and moving up and down two or more pallets, and the basic parking units are located close to each other in the width direction. A method for remodeling a parking device,
Removing at least one of the basic parking units to form an empty space in the pit;
A two-stage parking device that installs a seismic mount on the bottom of the pit in the empty space with a gap from the pit side, and sets the horizontal displacement of the seismic mount with respect to the horizontal force to be less than the gap with the pit side. A remodeling method is provided.

  Moreover, according to this invention, the parking equipment remodeled by the remodeling method mentioned above is provided.

  According to the present invention, at least one of the basic parking units is removed to form an empty space in the pit, and the seismic mount is installed on the bottom surface of the empty space. Part or whole can be dismantled to make effective use of pits.

In addition, since the seismic mount is installed on the pit bottom surface of the empty space with a gap from the pit side surface, it is not necessary to reinforce the pit side surface during installation.
Furthermore, since the horizontal displacement of the seismic frame with respect to the horizontal force is set to be less than the gap, damage to the pit side surface can be prevented even if the horizontal force acts during an earthquake.

It is explanatory drawing of the parking equipment of 1st Embodiment remodeled with the remodeling method of this invention. It is the front view (A) and side view (B) of the parking equipment of 2nd Embodiment remodeled with the remodeling method of this invention. It is a top view of the parking equipment of FIG. It is the front view (A) and side view (B) of the parking equipment of 3rd Embodiment remodeled with the remodeling method of this invention. It is a front view which shows the utilization form of the parking facility of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.

  FIG. 1 is an explanatory diagram of a remodeling method of the present invention and a parking facility of a first embodiment remodeled by this method. In this figure, (A) is before remodeling and (B) is after remodeling.

  In FIG. 1 (A), the two- and multi-stage parking device 9 before remodeling includes a plurality of basic parking units 3 that have a pit 1 below the loading / unloading height FL and move up and down two or more pallets 2. A plurality (three in this example) of basic parking units 3 are located close to each other in the width direction (left and right in the figure).

In the remodeling method of the present invention, first, as shown in FIG. 1B, at least one basic parking unit 3 positioned in the width direction is removed to form an empty space 4 in the pit. This empty space 4 has the size of the pit 1 of the removed basic parking unit 3.
The basic parking unit 3 to be removed may be two or more or all of them.

In the remodeling method of the present invention, the seismic mount 12 is then installed on the pit bottom surface 1b of the empty space 4 with a gap from the pit side surface 1a.
That is, the earthquake-resistant rack 12 is supported by the pit bottom surface 1b of the empty space 4 and is installed independently from the adjacent basic parking unit 3 and the pit side surface 1a.

In the remodeled parking facility 10, the total weight of the earthquake-resistant rack 12 is set to be lighter than the removed basic parking unit 3. Therefore, additional reinforcement of the pit bottom surface 1b can be eliminated.
Further, since the seismic mount 12 is installed on the pit bottom surface 1b with a gap from the pit side surface 1a, the reinforcement of the pit side surface 1a can be made unnecessary. This gap is preferably set to a size that does not hinder when a vehicle or a person is placed at the entry / exit height FL, for example, 10 to 30 mm.

  Further, the seismic mount 12 is set so that the horizontal displacement with respect to the horizontal force acting thereon is less than the gap with the pit side surface 1a.

In FIG. 1 (B), the seismic mount 12 has a single seismic cell 13.
The seismic cell 13 includes four seismic columns 14 spaced apart in the width direction and the front-rear direction, and a rigidity adding device 16 that reduces horizontal displacement of the four seismic columns 14.

  The four seismic columns 14 are, for example, H-shaped steel having high bending rigidity, and the lower ends thereof are fixed to the pit bottom surface 1b and are erected vertically.

In this example, the rigidity adding device 16 is a plurality of braces 16a installed between the four seismic columns 14 in the width direction and the front-rear direction.
In this example, two braces 16a are obliquely crossed and attached in an X shape between two seismic columns 14 adjacent in the width direction and the front-rear direction.
That is, the single seismic cell 13 reduces the horizontal displacement of the seismic column 14 by a total of eight braces 16a.

  With the above-described configuration, the horizontal displacement with respect to the horizontal force acting on the seismic mount 12 can be set to be less than the gap with the pit side surface 1a.

  In FIG. 1B, the seismic mount 12 further includes a plurality of large beams 18, a plurality of small beams 20, and a floor surface 22.

A plurality of (two in this example) large beams 18 are respectively supported by the four seismic columns 14 of the earthquake-resistant cell 13 at two points, and extend horizontally in the width direction or in the front-rear direction (in this example, the front-rear direction). The girder 18 is, for example, H-shaped steel, and has rigidity capable of supporting the entire weight of a load (for example, a vehicle) placed on the floor surface 22.
The girder 18 is preferably firmly fixed to the end face of the seismic column 14 by welding or bolts and nuts.

The plurality of small beams 20 are supported by the plurality of large beams 18, extend horizontally in the horizontal direction (in this example, the width direction) perpendicular to the large beams 18, and are spaced apart from each other. The beam 20 may be H-shaped steel, for example.
The small beam 20 is preferably firmly fixed to the end face of the large beam 18 by welding or bolts and nuts.

The floor surface 22 is supported by the plurality of small beams 20 and extends horizontally. The floor surface 22 may be composed of a plurality of plate materials.
The floor surface 22 is preferably firmly fixed to the end surface of the beam 20 with bolts and nuts.

  The interval between the small beams 20 and the rigidity of the floor surface 22 are set in consideration of the weight and movement of a load (for example, a vehicle) placed thereon.

  By the remodeling method of 1st Embodiment mentioned above, the earthquake-resistant rack 12 can be installed independently from the adjacent basic parking unit 3 and the pit side surface 1a. Moreover, since the rigidity addition apparatus 16 prevents the seismic column 14 from being displaced in the width direction and the front-rear direction, even if a horizontal force is applied during an earthquake, the pit side surface 1a can be prevented from being damaged without being reinforced.

  FIG. 2: is the front view (A) and the side view (B) of the parking equipment 10 of 2nd Embodiment remodeled with the remodeling method of this invention.

In FIG. 2, the seismic mount 12 has a pair of seismic cells 13 on the left and right sides installed at both ends in the width direction, and a pair of auxiliary columns 15 before and after being positioned between the pair of seismic cells 13.
The pair of auxiliary columns 15 have the same length as the seismic column 14 and are spaced apart in the same width direction and front-rear direction as the seismic column 14.
In this example, the auxiliary column 15 is an H-shaped steel having the same bending rigidity as that of the seismic column 14, and the lower end thereof is fixed to the pit bottom surface 1b and is erected vertically.
The auxiliary pillars 15 are not limited to one pair, and may be a plurality of pairs.

In FIG. 2, a plurality of (in this example, five) large beams 18 are supported at two points in the front and back by the earthquake-proof column 14 or the auxiliary column 15 of the earthquake-resistant cell 13 and extend horizontally in the front-rear direction in this example.
A plurality (9 in this example) of the small beams 20 are supported by the plurality of large beams 18, and in this example, extend horizontally in the width direction and are spaced apart from each other in the front-rear direction. The distance in the front-rear direction is set in consideration of the weight and movement of a load (for example, a vehicle) placed thereon.
The floor surface 22 is supported by the plurality of small beams 20 and extends horizontally.

FIG. 3 is a plan view of the parking facility 10 of FIG.
In this figure, the X direction is the width direction and the Y direction is the front-rear direction. Further, in this figure, illustration of the floor surface 22 is omitted.

  In FIG. 3, reference numeral 24 denotes a car stop. In this example, four vehicles 6 can be parked on the floor surface 22 in the X direction (width direction).

Moreover, in this example, the earthquake-resistant rack 12 has the opening part 26 and the raising / lowering equipment 28 which were provided in the floor surface 22 of the entrance / exit height FL.
The opening 26 communicates the outside and the inside of the pit. The opening 26 is provided inside a rectangular portion composed of two adjacent large beams 18 and two small beams 20. The opening 26 is preferably provided with a door (not shown) that can be opened and closed.
The elevating equipment 28 can be moved up and down through the opening 26. The elevating equipment 28 is a ladder in this example, but may be a staircase.

  By providing the opening 26 and the lifting equipment 28 described above, a person can enter the pit through the opening 26, and the pit 1 can be effectively used as a storage space.

  FIG. 4 is a front view (A) and a side view (B) of the parking facility 10 of the third embodiment modified by the modification method of the present invention.

In FIG. 4, the earthquake-resistant rack 12 has a pair of left and right earthquake-resistant cells 13 installed at both ends in the width direction, and the auxiliary column 15 in FIG. 2 is omitted.
In this example, the opening 26 has no door, and the lifting equipment 28 is a staircase having a handrail.
Other configurations are the same as those of the second embodiment.

FIG. 5 is a front view showing a usage pattern of the parking facility 10 of FIG.
As shown in FIGS. 5A and 5B, the modified floor 22 can be used as a parking lot for the vehicle 6, a bicycle parking lot, or an installation place for the delivery box 7.
Further, the pit 1 can be effectively used as a storage space for the tire rack 8 or the like.

  According to the above-described embodiment of the present invention, at least one of the basic parking units 3 is removed to form the empty space 4 in the pit, and the seismic mount 12 is installed on the pit bottom surface 1b of the empty space 4. It is possible to effectively use the pit 1 by disassembling part or all of the two- and multi-stage parking apparatus 9.

For example, by providing the floor surface 22 on the upper surface of the pit 1 (entry / exit height FL), the floor surface can be used as a parking lot, a bicycle parking lot, or a delivery box.
Further, by providing the opening 26 and the lifting equipment 28, the inside of the pit can be effectively used as a storage space for a tire rack or the like.

Moreover, since the seismic mount 12 is installed on the pit bottom surface 1b of the empty space 4 with a gap from the pit side surface 1a, it is not necessary to reinforce the pit side surface 1a during installation.
Further, since the horizontal displacement of the seismic mount 12 with respect to the horizontal force is set to be less than the gap, damage to the pit side surface 1a can be prevented even if a horizontal force acts on the upper part of the pit during an earthquake.

  Note that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. Moreover, the “remodeling method of the two-multistage parking apparatus” of the present invention is an invention of a manufacturing method of the “modified two-multistage parking apparatus”.
