Description

  The present invention relates to a flat parking facility.

  When Japan boiled in a bubble economy, the shortage of parking lots became serious as the private car ownership rate increased. In order to cope with such a shortage of parking lots, a mechanical parking device has been born in which cars are stacked on a pallet and parked. Mechanical parking devices are widely used mainly in urban areas of Japan, such as Tokyo and Osaka, where parking space is scarce. As a mechanical parking device, for example, as shown in Patent Document 1, a type that is installed in an underground pit portion formed underground is known.

  As shown in FIG. 1, the flat parking facility 10 includes an underground pit portion 12, a pillar 14, a beam 16, and a deck portion 18. In the flat parking facility 10, three parking spaces SP for parking the vehicle in the length direction X are provided in the width direction Y. The underground pit portion 12 is a substantially rectangular parallelepiped pit formed by excavating the ground and solidifying all sides with concrete, and has an upper surface opening portion 20, four side surface portions 22a to 22d, and a bottom surface portion 24. ing. In FIG. 1, the side surface portions 22a to 22d include four side surfaces 22a and 22b on the back side and side surfaces 22c and 22d on the near side.

  The column 14 is an H-shaped steel having a standard cross-sectional dimension H × B × t1 × t2 of “100 mm × 100 mm × 6 mm × 8 mm” and a height Ha of 1,600 to 4,000 mm. The column 14 is installed on the bottom surface portion 24 with the base plate 26 and the mortar 28 interposed therebetween. Further, two L-shaped joining members 30 are provided on both sides of the column 14 so as to sandwich the end portion on the bottom surface side of the column 14. In this L-shaped joining member 30, one joining portion is fixed to the column 14 with two bolts, and the other joining portion is secured to the base plate 26 with anchor bolts. As described above, the column 14 and the base plate 26 are fixed.

  In addition, about the installation number of the pillar 14, it determines with the magnitude | size of the parking space SP of one vehicle. For example, as shown in FIG. 2A, when the parking space SP of one vehicle has a length L1 of 5,000 to 7,200 mm and a width W1 of 2,200 to 3,000 mm, It is preferable to use a total of six pillars 14 for one parking space SP. In this case, among the six pillars 14, it is preferable to arrange two in the length direction X and three in the width direction Y. Moreover, when providing multiple parking space SP along the width direction Y, as shown to FIG. 2 (B), in the boundary part P of adjacent parking space SP, it does not install each pillar 14 separately, respectively. It is preferable to use the column 14 at the boundary portion P.

  The beam 16 is an H-shaped steel having a standard cross-sectional dimension H × B × t1 × t2 of “200 mm × 100 mm × 5.5 mm × 8 mm” and has a length of 5,000 to 7,000 mm. The beam 16 is provided along the length direction X, and is not provided along the width direction Y. As shown in FIG. 3, a portion of the beam 16 that is joined to the column 14 is fixed to the column 14 by two L-shaped joining members 32. The two L-shaped joining members 32 are provided so as to sandwich both ends of the end portion of the column 14 on the beam side. In this L-shaped joining member 32, one joining portion is fixed to the column 14 with two bolts 34, and the other joining portion is secured to the beam 16 with two bolts 36. .

  As shown in FIG. 4, both ends of the beam 16 are fixed to L-shaped joining members 38 provided on the side surface portions 22a and 22c of the underground pit portion. In this L-shaped joining member 38, one joining portion is fixed to the beam 16 with two bolts 40, and the other joining portion is secured to the side portions 22a and 22c with two anchor bolts 42. Has been.

  Here, in this embodiment, the column 14 and the beam 16 are not joined by welding as in the case of a ramen structure or a pin structure, but are joined only by bolts without using welding. Further, the beam 16 is provided only in the length direction X and is not provided in the width direction Y. For this reason, there is a concern about insufficient strength due to no welding or not installing the beam 16 in the width direction Y, in particular, insufficient strength against horizontal force due to an earthquake or the like. In this embodiment, both ends of the beam 16 are connected to the underground pit portion. By fixing to the side portions 22a and 22c, the strength deficiency at the joint portion between the column 14 and the beam 16 is resolved, and the strength of the entire flat parking facility 10 is sufficiently secured.

  In addition, if the column 14 and the beam 16 are joined by welding, the hot dip galvanization provided for preventing rust on the column 14 and the beam 16 may be peeled off. Therefore, there is no possibility that the hot dip galvanizing of the column 14 and the beam 16 will be peeled off.

  As shown in FIG. 1, the deck portion 18 is configured by arranging a plurality of elongated deck plates 46 extending in the width direction Y along the length direction X. Each deck plate 46 and the beam 16 are fixed by bolts (not shown). Each deck plate 46 has a length L2 of 180 to 220 mm and a width W2 of 2,500 to 3,000 mm. For example, it is preferable to arrange 22 to 38 deck plates 46 for the beam 16 having a length of 5,000 to 7,000 mm.

  As described above, the deck portion 18 is not configured by a single deck plate, but a plurality of elongated deck plates 46 are arranged side by side in the length direction X. Therefore, the deck portion 18 is added to the deck portion 18 due to the weight of a car or the like. The power is dispersed. Thereby, since the force applied to the beam 16 and the column 14 through the deck portion 18 is made uniform, the force applied to the joint portion between the column 14 and the beam 16 is reduced. Therefore, the strength of the flat parking facility 10 as a whole can be sufficiently ensured.

  Next, the installation method of a plane parking facility is demonstrated along the flowchart shown in FIG. First, a mechanical parking device (not shown) installed in the underground pit part 12 is removed. As a mechanical parking device, a vehicle is placed on a pallet and stacked and parked. This mechanical parking device, for example, lowers a pallet on which a vehicle is placed to an underground pit portion and stores the pallet on the underground pit portion when the vehicle is stored. On the other hand, when leaving the car, the pallet is raised to the ground so that the car can be taken out from the pallet.

  Next, as shown in FIG. 6, after the mechanical parking device is removed, the pillar 14 is installed on the bottom surface portion 24 of the underground pit portion. The columns 14 are installed at predetermined intervals in the length direction X and the width direction Y of the underground pit portion 12. For example, as shown in FIG. 2, with respect to the length direction X, the distance L2 between the side surface portions 22a, 22c of the underground pit portion and the pillar 14 is set to 1,200 to 2,000 mm, and the distance L3 between the adjacent pillars 14 is set. It is preferable to make it 2,500-3,000 mm. Further, with respect to the width direction Y, it is preferable to install the columns 14 at an interval W2 of 1,100 to 1,500 mm.

  Next, as shown in FIG. 7, the beam 16 is installed on the column 14 along the length direction X. After the beam 14 has been pillared 14, both ends of the pillar 14 are sandwiched between two L-shaped joining members, and one of the L-shaped joining members and the pillar 14 are fixed with bolts 34. Then, the other joint and the beam 16 are fixed with a bolt 36. The column 14 and the beam 16 are joined only by bolts without using welding. In addition, L-shaped joining members 38 are installed on the side portions 22a and 22c of the underground pit portion at locations corresponding to the installation positions of the beams 16, respectively. In this L-shaped joining member 38, one joining portion and the beam 16 are fixed with a bolt 40, and the other joining portion is secured to the side surface portions 22 a and 22 c with an anchor bolt 42.

  Next, as shown in FIG. 8, the deck portion 18 is installed by arranging a plurality of elongated deck plates 46 on the beam 16 along the length direction X. The installation of the deck portion 18 closes the underground pit portion 12. For example, when the beam 16 has a length of 5,000 to 7,000 mm, it is preferable to arrange 22 to 38 deck plates 46. The beam 16 and the deck plate 46 are fixed with bolts. Finally, in the deck portion 18, a car stop 48 is installed at a predetermined position of the parking space SP, and a line is drawn with a paint or the like at the boundary portion of the parking space SP so that the position of the parking space SP can be understood (see FIG. 1). .

  As described above, the installation method of the flat parking facility allows the flat parking facility 10 to be installed with only the pillars 14, the beams 16, and the deck plate 46 without backfilling the underground pit portion 12. Costs can be greatly reduced. Further, since the column 14 and the beam 16 are joined by manual work using only bolts without using welding, the construction period and cost can be greatly reduced. Moreover, even if it is joining only a volt | bolt, since the beam 16 is being fixed to the side parts 22a and 22c of an underground pit part, the intensity | strength in the plane parking equipment 10 whole is fully ensured.

  In addition, in this invention, although the both ends of the beam 16 joined only with the pillar 14 and the volt | bolt are fixed to the side parts 22a and 22c of an underground pit part, the intensity | strength of the plane parking equipment 10 whole is ensured, Only at least one of both end portions of the beam 16 may be fixed to the side surface portions 22a and 22c of the underground pit portion. Further, in the present invention, the beam 16 is provided only along the length direction X of the underground pit portion 12, but instead, the beam 16 is provided only along the width direction Y of the underground pit portion 12. Even if it is a case, the same effect is acquired.
