The entry section deck 5a is fixed to the beam members 12 and 12A by welding, anchor bolts, or the corner angle of the pit 4 by welding or the like.

  The pit type multistory parking garage 1 is provided with a gate 13 that can be moved up and down on the approach path 5, allowing the vehicle to pass into the pallet 2 by raising the gate 13, and lowering the gate 13 to lower the pallet. It has a configuration that restricts the passage of vehicles to the inside and prevents them from entering. The gate 13 is supported by two guide rails 14 and 14 erected in parallel with the pillars 11 and 11 facing the approach path 5 and is moved up and down by a lifting motor (not shown). . The guide rails 14 and 14 are fixed to the column members 11 and 11 with bolts or the like, but may be configured to be fixed by welding or other means.

  The gate 13 has a shape in which a mesh body 13b is combined with a gate body 13a in which a metal prism is welded in a rectangular shape, and a plurality of rollers 13c (FIGS. 3 and 4) fixed to the outer peripheral sides of the left and right vertical pieces of the gate body 13a.

The support plate 15 includes a closing plate 16 for preventing rainwater from entering the pit 4 during heavy rain, a water-inhibiting rubber 17, and The side flooding prevention plate 18 is fixed.

The closing plate 16 is formed of a flat plate such as a metal plate material or a resin plate material, is formed to have substantially the same width as the gate body 13a, and is fixed to the gate body 13a with screws or the like. The inundation preventing rubber 17 is formed of an elastically deformable rubber having a U-shaped cross section, and the support plate 15 is positioned and fixed in the upper opening, and the U-shaped portion is crushed when pressed downward. It can be elastically deformed. The side flood prevention plate 18 has a function of reducing a gap between the gate 13 and the guide rails 14 and 14 and is configured by a flat plate such as a metal plate material or a resin plate material, and approaches the front surface of the guide rail. By reducing the gap between the gate 14 and the gate 13, the amount of inundation such as rainwater passing through the gap is limited. Cover plates 19, 19 are fixed in the longitudinal direction along the inundation preventing rubber 17.

  A side closing plate 20 is fixed between the guide rails 14 and 14 and the rising wall 6 to prevent rainwater or the like from entering the pit 4. Specifically, as shown in detail in FIGS. 3 and 4 and the like, the side closing plate 20 is formed by bending a metal plate material, and the lower side portion 20a is anchored to the foundation concrete portion constituting the pit 4, and the rising wall 6 The vertical portion 20 b facing the base is anchored to the rising wall 6. The vertical portion 20c on the guide rail 14 side and the closing plate 14a below the guide rail 14 are connected and fixed with a caulking agent or the like to prevent intrusion of rainwater or the like.

  As described above, the gate 13 is supported by the entrance path 5 of the pit type multi-story parking garage 1 so as to be able to move up and down, and restricts or permits the passage of the vehicle into the pallet 2. The lower infiltration preventing rubber 17 is lowered so as not to contact the entry deck 5a, and is set to be stopped at a normal position where a space is formed below the gate 13. Further, when it is raining, the gate 13 descends so that the lower infiltration prevention rubber 17 is compressed in contact with the entry deck 5a and stops so that the infiltration prevention rubber 17 and the entry deck 5a are in close contact with each other. It is set so that rainwater does not enter the pit 4 from the space below the gate 13. A protective cover plate 21 (see FIG. 3) is fixed in front of the gate 13 along the vertical direction, and protects the driver and the operator from pinching fingers or the like when the gate 13 is raised or lowered. It is.

  The operation of the inundation preventing device of the pit type multi-story parking lot 1 of the present embodiment configured as described above will be described below. When entering the pit type multistory parking lot 1 of the present embodiment, for example, in the case of the middle pallets 2B and 2B, the gate 13 is raised and the vehicle enters the pallet 2B through the entry deck 5a of the entry path 5. Can be placed. Thereafter, when the gate 13 is closed, the gate 13 is stopped at a normal position (see FIG. 5b) where a space is formed below the gate when it is not raining, and rainwater enters the pit 4 below the normal position when it rains. Stop at the flood prevention position (see FIG. 5a) to prevent.

  This inundation prevention position stops the gate 13 further below the normal position, and since there is no space below the gate 13, inundation of rainwater collected around the pit 4 into the pit 4 is prevented. In other words, at the flooding prevention position, the gate 13 is further lowered below the normal position, and the flooding prevention rubber 17 is pressed against the entry deck 5a and is brought into close contact with the deformation. Thereby, even if rainwater accumulates on the ground surface 3, intrusion of rainwater from the lower infiltration prevention rubber 17 and the entry deck 5a is prevented, and the gap between the guide rails 14 and 14 and the gate 13 becomes side inundation. Since it is shrunk by the prevention plates 18, it is possible to reduce water intrusion into the pit 4 as much as possible. In addition, since the gap between the rising wall 6 and the guide rails 14 and 14 is closed by the closing plate 20, flooding from the gap is prevented.

  When the vehicle is placed in the lower pallets 2A, 2A ..., the middle pallets 2B, 2B are horizontally moved so as to open the upper part of the pallet to be used out of the three pallets, and into the open space. Pallet 2A is raised. Then, the gate 13 can be raised and the vehicle can be moved in and out through the entry deck 5a. After the vehicle is moved in and out of the pallet 2A, the gate 13 is lowered to restrict the vehicle from entering and leaving. When the gate 13 descends, the gate 13 stops at a normal position with a space downwardly in normal weather. On the other hand, when it rains in the rain, the gate 13 is stopped at the inundation preventing position where there is no space below, and the intrusion of rainwater into the pit 4 is prevented.

  Further, when the vehicle is placed in the upper pallets 2C, 2C..., The middle pallets 2B and 2B are horizontally moved so as to open the lower part of the pallet to be used among the three pallets, and the open space is opened. The pallet 2C is lowered inside. Then, the gate 13 can be raised, and the vehicle can be moved in and out through the entry deck 5a. When the gate 13 is closed, the gate 13 is stopped at a normal position with a space below when it is not raining, and is stopped at a flood-preventing position where there is no space below when it rains, thereby reducing water intrusion into the pit 4 as much as possible. .

  In a normal pit type multistory parking lot with a large amount of precipitation such as guerrilla heavy rain, a large amount of rainwater flows into the pit from the outer surface of the outer periphery, and the amount of rainwater inflow is greater than the amount of drainage from the drain pump in the pit. The rectangular pit in plan view is filled with rain water, and there is a risk of damage to the vehicle located in the lower stage. In the pit type multi-story parking lot 1 of this embodiment, the three sides of the outer periphery of the pit 4 are rising walls. 6 is surely prevented from being flooded, and a large amount of rainwater flows into the pit 4 by the closing plate 16, the flooding prevention rubber 17 and the side flooding prevention plate 18 located at the lower part of the gate 13 on one side of the approach path 5. In order to prevent this, the inflowing rainwater is sufficiently drained by the drainage pump in the pit 4 and the pit 4 is not filled with rainwater, causing damage to the vehicles mounted on the lower pallet 2A. do not do.

  In other words, rainwater collected on the outer periphery of the pit 4 due to heavy rain is prevented from flowing into the pit 4 from the entrance path 5 on one side because the rising wall 6 prevents the rainwater from flowing into the three sides of the rectangular pit in plan view. The rainwater is prevented from flowing in by the closing plate 16 fixed below the gate 13 and the inundation prevention rubber 17 being in close contact with the upper surface of the entry deck 5a of the approach path 5, and the gap between the gate 13 and the guide rails 14, 14 is Inflow of rainwater is restricted by the side flooding prevention plates 18, 18, and the gap between the guide rails 14, 14 and the rising walls 6, 6 is closed by the side closing plates 20, 20. The amount of water flowing into the pit is reduced and drained by the drain pump in the pit, so that it is possible to prevent rainwater from accumulating and filling the pit 4.

  In the inundation prevention device of the pit type multistory parking lot 1 according to the present embodiment, a rain sensor or a rainfall sensor is provided, and the gate 13 is operated during rain or heavy rain, and the space below the gate 13 is stopped at the inundation prevention position. Alternatively, the infiltration prevention rubber 17 may be brought into close contact with the entry portion deck 5a to limit the infiltration into the pit 4. Moreover, although the example in which the inundation preventing rubber 17 abuts on the entry section deck 5a of the approach path 5 has been shown, it does not abut on the deck 5a, but abuts on the ground surface 3 and the corner angle of the entrance path 5. It may be configured. That is, any part may be used as long as it closes the space below the gate 13.

  In the above-described embodiment, the water-inhibiting rubber 17 having a U-shaped cross section is used as the water-inhibiting member. However, the water-inhibiting member is not limited to this shape. Alternatively, a water-inhibiting rubber 17A having a substantially L-shaped cross section may be used. In FIG. 6, components having the same configuration and function as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In the inundation preventing apparatus of the modification shown in FIG. 6, the entrance path 5 of the vehicle to the pallet is provided with a gate 13A that can be raised and lowered to restrict or permit passage of the vehicle, and a support plate 15A is provided below the gate 13A. The cover plate 16A is fixed and connected to the support plate 15A to prevent rainwater from entering the pit 4. A water immersion prevention rubber 17A is fixed below the support plate 15A and the closing plate 16A.

This water-inhibiting rubber 17A moves up and down together with the gate 13A, and comes into contact with a rubber shock-absorbing plate 5b fixed to the upper part of the entry deck 5a when lowered to the water-inhibiting position shown in FIG. 6a. . The buffer plate 5 b is closed with a caulking agent 5 c or the like in the gap between the corner plate fixed to the corner of the ground surface 3 of the pit 4. The buffer plate 5b is not necessarily required, and may be configured to directly contact the loading section deck. Although not shown, it is preferable to reduce the gap between the gate 13A and the guide rail and the gap between the guide rail and the rising wall with a side block plate or the like as in the above embodiment.

  In the inundation preventing rubber 17A configured in this way, the gate 13A stops at the normal position shown in FIG. 6b when there is no rain, and there is a space below, but when it rains, the inundation prevention position shown in FIG. 6a below the normal position. To stop. In this flooding prevention position, the flooding prevention rubber 17A fixed below the gate 13A comes into contact with the buffer plate 5b fixed on the loading portion deck 5a, and the front end portion thereof is elastically deformed to be in close contact with the buffer plate 5b. For this reason, even if rainwater accumulates on the ground surface 3 due to heavy rain or the like, the inundation preventing rubber 17A below the gate 13A provided in the approach path 5 comes into close contact with the buffer plate 5b on the ground surface 3 and enters the pit 4. Prevent intrusion of rainwater.

  This water-inhibiting rubber 17A has a substantially L-shaped cross section, has a simple structure, can achieve cost reduction, can be easily attached and detached, and has an advantage of easy maintenance. Further, when a large amount of rainwater is accumulated on the ground surface 3, the tip of the infiltration prevention rubber 17A is pressed downward by the weight of the rainwater, so that the infiltration prevention performance is improved and the inundation into the pit 4 is efficiently performed. It can be well prevented. In addition, it is preferable to extend both sides of the water-inhibiting rubber 17A so as to have a function of integrally closing a gap between the guide rail and the rising wall.

  Another embodiment of the present invention will be described in detail with reference to FIGS. In this embodiment, in the above-described embodiment, the gate is raised so that the vehicle can pass to the pallet, whereas the gate that moves up and down to restrict or permit the vehicle to pass into the pallet is a pit. The vehicle is lowered inward, and the vehicle can enter the pallet with the gate lowered. Other substantially equivalent configurations are denoted by the same reference numerals, and detailed description thereof is omitted.

  7-10, the pit type multistory parking garage 1A of this embodiment can accommodate three vehicles of two stages, and includes three pallets 2D, 2E, and 2F. The pit 4A is formed by digging underground from the ground surface 3 and has a size and depth that can accommodate two pallets. In the state shown in the figure, one pallet 2F is located in the pit, and two pallets 2D and 2E are located at the same height as the ground surface 3. It faces 5 and can enter and exit.

  Also in this embodiment, the pit 4A dug underground is formed in a rectangular shape in plan view, and rising walls 6 are formed on three sides other than the approach path 5. A gate 23 that restricts or permits passage of the vehicle into the pallet is located on one side that functions as the approach path 5 so as to be movable up and down.

  In this embodiment, the gate 23 for restricting or permitting the passage of the vehicle into the pallet 2 can be lifted and lowered into the pit 4A by a lifting device such as a motor (not shown). The gate 23 is positioned at the front of the vehicle so as to block the passage and restrict passage, and at the lowered position, the gate 23 is lowered deeper than the ground surface 3 so that the vehicle can freely pass through. It is something to allow.

  The gate 23 is formed of a gate main body 23a formed in a rectangular shape with an iron square pipe and a mesh 23b positioned within the frame of the gate main body, and a closing plate 23c extending to the entire width is fixed below. This gate 23 is fixed to an elevating guide 23d that is mounted on one flange of an H-shaped steel column 11 constituting a framework for supporting a plurality of pallets so as to be movable up and down, and can be accommodated in the pit 4A.

  At the upper corner of the pit 4A on the approach path 5 side, a corner angle 4b is fixed as an end edge of the pit 4A, and a protrusion of the approach path 5 is formed. Then, between the corner angle 4b and the gate 23, a receiving plate 5b is welded and fixed as a protruding portion of the approach path 5 so as to extend horizontally from the ground surface 3 toward the inside of the pit 4A. The width and dimensions of the receiving plate 5b are set so that the gap between the receiving plate 5b and the gate 23 is reduced.

On the other hand, under the gate 23, an infiltration prevention material 24 that contacts the receiving plate 5b fixed to the corner angle 4b from below is fixed, and a packing 25 is fixed on the upper surface of the infiltration prevention material 24. The packing 25 is formed of an elastically deformable rubber plate or the like. The infiltration preventing member 24 and the packing 25 constituting the inundation preventing member can be moved up and down together with the gate 23, and are configured to contact the lower surface of the receiving plate 5b at the inundation preventing position raised from the normal position.

  In the present embodiment, as means for closing the gap between the gate 23 and the rising wall 6, the water stop plates 26 and 26 and the flood prevention plates 27 and 27 are provided at both end portions of the gate. The water stop plate 26 is formed of a rectangular plate material, is formed of a metal plate, a plastic plate, a rubber plate, or the like, and is fixed to both lower sides of the gate 23. Further, the water immersion prevention plate 27 is bent on a metal plate and fixed to the rising wall 6 by anchoring. And it arrange | positions so that the front side bending part of the infiltration prevention board 27 and the water stop plate 26 may approach, and the small clearance gap is formed between both. The gap between the column 11 and the corner angle 4b is closed by a hole closing plate 28 welded to the corner angle 4b. A protective plate 29 is fixed in the vertical direction in front of the infiltration prevention plate 27 and has a function of protecting the driver and the operator from pinching fingers and the like.

  In the pit type multistory parking garage 1A configured as described above, the approach path 5 is closed at the position where the gate 23 is raised and the passage of the vehicle is restricted, so that the vehicle cannot be taken in and out. When the vehicle is taken out from the pallet 2 or the vehicle is put into the pallet 2, when the gate 23 is lowered, the gate 23 is accommodated in the pit 4A, and the approach path 5 is opened so that the vehicle can pass.

  When the loading / unloading of the vehicle is completed, the gate 23 is raised. When the weather is fine, the gate 23 stops at a low position (normal position) as shown in FIG. 10a, and the receiving plate 5b fixed to the corner angle 4b and the packing 25 of the flood prevention plate 24 are separated from each other. 23 is raised to a high position as shown in FIG. 10b, and stops at the flooding prevention position. In this flooding prevention position, the flooding prevention material 24 and the packing 25 that have risen together with the gate 23 are welded and fixed so as to extend into the pit 4A from the corner angle 4b fixed to the ground surface 3 at the upper end of the pit 4A. Contact the plate 5b.

  For this reason, even if rainwater accumulates on the ground surface 3 due to heavy rain or the like, rainwater can be prevented from entering the pit 4A. Further, since the gap between the gate 23 and the rising wall 6 is blocked by the water stop plate 26 and the flood prevention plate 27, the flood from the gap can be reduced, and the interior of the pit 4A is filled with rain water or the like. Can be prevented. Furthermore, since the gap between the column 11 and the corner angle 4b is closed by the hole closing plate 28, water intrusion from this gap can be reduced.

  The receiving plate 5b as a receiving member with which the inundation preventing material 24 and the packing 25 abut is formed of a metal plate welded to the corner angle 4b, but is a metal material having a substantially T-shaped cross section. It may be formed integrally with the corner angle. Moreover, although the example of the flat receiving plate was shown, it can also be set as appropriate shapes, such as a square pipe.
