[0023]

According to the present invention, the rainwater that has fallen on the floor panel body on the upper floor of the multi-storey car park flows down to the vertical shaft through the first draining means, and the rainwater from the vertical shaft is the second draining means. Received at
Furthermore, a third drainage means provided on the lower surface side of the H-section steel, and a fourth drainage means
The rainwater that has flowed onto the ground, a drainage groove formed on the ground, or the like via the drainage means can efficiently drain the rainwater that has fallen on the upper surface of the floor panel body. Therefore, rainwater will not leak to the floors below the floor panel body. Therefore, a person who parks a car on the lower floor and gets on and off does not get rainwater and does not feel uncomfortable. Further, the floor panel main body is formed by a plate portion integrally formed with the vertical frame and a plurality of plate-shaped plates so that the floor surface is closed, and is constituted by a conventional net body that allows the floor above to be seen from below. Unlike the floor panel itself, you cannot see the upper floors from the bottom, which gives a sense of security, especially for women.

Further, in the present invention, as the first drainage means, a gap is formed between the plate portion of the vertical frame and the plate, and between the plates over substantially the entire length in the longitudinal direction. Rainwater that has fallen on the upper surface of the floor panel main body can be efficiently drained to the vertical shaft via the.

Further, in the third aspect, the plate portion of the vertical frame and the end portion of the plate are bent and formed into a substantially L shape, and the rainwater flows vertically from the gap between the bent pieces. Since it is designed to be drained to the vertical panel, rainwater that has fallen on the upper surface of the floor panel body can be efficiently drained to the vertical shaft through this gap, and the bending pieces increase the strength of the plate and plate. Can be improved.

According to a fourth aspect of the present invention, as the first drainage means, the end portions of the vertical frame between the plate portions and between the plates are brought into contact with each other, and the end portions of the plate portions and the plate on the contact surface side are brought into contact with each other. Since a plurality of drainage holes are formed along the longitudinal direction at predetermined intervals, rainwater can be efficiently flowed vertically through the drainage holes while keeping the strength of the plate portion and the plate of the floor panel body constant. Can be washed away.

Further, in the present invention, as the second drainage means, a hole is formed at a side plate located at an end of the vertical shaft, and rainwater is discharged from the vertical shaft through the hole. Therefore, rainwater flowing vertically through the holes in the side plates can be efficiently discharged to the outside.

Further, according to the present invention, drainage grooves are integrally formed inside the lower portions of the left and right vertical frames constituting the floor panel body, and the horizontal caverns located above the drainage grooves of the vertical frames are opened at the upper surface. As a shape, the end of the horizontal shaft is opened to the drain groove side of the vertical frame, a hole for draining is formed in the bottom of the vertical shaft located above the horizontal shaft, and the rainwater that has dropped from the hole is drained horizontally. In addition, by draining water through the drains of the vertical frame, the rainwater that has flowed down the vertical shaft can be drained from the horizontal shaft to the drains of the vertical frame through the vertical shaft itself and the holes formed in the vertical shaft. The two drainage routes will be formed, and rainwater can be drained efficiently.

Further, in the present invention, the contact between each member of the vertical frame, the plate, the vertical shaft, the horizontal shaft, and the side plate is point contact or line contact, and the entire floor panel main body in which the respective members are fixed by welding is used. Since it is plated, compared to the case where the entire floor panel main body, which is made by welding the members by making surface contact with each other, is plated, each member is point-contacted or line-contacted. It is possible to prevent the discoloration due to non-plating and the occurrence of rust, so that the appearance is not damaged, the product value is not deteriorated, and the repair is not required after the construction. In addition, it is possible to easily carry out washing or the like later.

According to the eighth aspect of the present invention, the floor panel main body is arranged in the inner space of the H-shaped steel, and the upper surface of the floor panel main body and the upper surface of the H-shaped steel are laid substantially flush with each other. The upper surface of the H-shaped steel is also used as the floor surface in the same manner as the upper surface of the plate, and the area of the floor panel main body is smaller if the H-shaped steels are arranged at the same intervals as compared with the case of so-called power flow. It is possible to reduce the weight of the floor panel body. Therefore, the cost of the floor panel body can be reduced.

In the ninth aspect, the third drainage means is a gutter having an open top surface.
It can receive all the rainwater drained from the floor panel body, does not leak the rainwater, and the structure of the gutter body has an open top surface, so that the gutter body can be easily manufactured.

Further, in claim 10, since the drainage groove is integrally formed in the H-shaped steel as the third drainage means, it is not necessary to additionally attach a gutter body for receiving rainwater from the floor panel main body. The construction can be simplified and the cost can be kept low.

In the eleventh aspect of the invention, since the fourth drainage means is a vertical gutter installed along the side surface of the pillar, a general downspout can be used as the downspout. Can be constructed at low cost, and does not impair the appearance.

In the twelfth aspect, the fourth drainage means is a hose provided along the side surface of the column and having elasticity and flexibility, so that the drainage port of the hose is arranged on any side surface of the column. It can be installed, and can respond flexibly according to the construction site. Also, the cost can be reduced,
Construction is also easy.

According to the thirteenth aspect, since the fourth drainage means is provided inside the cylindrical column, the drainage device is not attached to the outer surface of the column, so that the drainage device is an obstacle. There is no need to reduce the space in the parking lot and it is easy to move in and out of the car. In addition, the appearance of the drainage device is not damaged as compared with the case where the drainage device is provided on the outer surface of the pillar.

According to the fourteenth aspect of the invention, the plate portion of the vertical frame and the upper surface of the plate are formed with projections in a substantially eight shape at a predetermined interval over the entire length in the longitudinal direction. Therefore, a plurality of plates are laid. In this case, the protrusions have a continuous zigzag pattern, so that the slip of the tire of the automobile can be more completely prevented, and the protrusions can also increase the strength of the plate itself. Moreover, the projections provided on the upper surface of the plate reduce splashes of rainwater when the vehicle is running, and also reduce splashes of rainwater when a person walks. Furthermore, the projections of the rainwater that has been vigorously falling can serve as a guide, and the rainwater can be smoothly drained.

In the fifteenth aspect, since the upper surface of the plate is an inclined surface that descends from the substantially central portion to both sides, rainwater that has fallen on the upper surface of the plate can be smoothly drained through the inclined surface. Therefore, the rainwater is not retained on the upper surface of the floor panel body, and the user of the parking lot does not feel uncomfortable due to the retention of the rainwater.

Next, the drainage of rainwater that has fallen on the second floor of the multi-storey parking lot will be described in detail. First, when the drainage hole 22 is not formed in the vertical shaft 5, rainwater is drained as follows. That is, the rainwater that has fallen on the upper surface of the floor panel body 1 flows down into the vertical shaft 5 from the gap 12 (or the drain hole 21 in FIG. 6) formed between the plate portion 6 and the plate 8. Then, the rainwater that has flowed down into the vertical shaft 5 flows toward the end of the vertical shaft 5, and the holes 18 of the side plate 3
Will be drained to the outside.

Next, a case where the drainage hole 22 as shown in FIGS. 7 and 8 is formed at the bottom of the vertical shaft 5 will be described. Rainwater that has fallen onto the upper surface of the floor panel body 1 flows down into the vertical stalk 5 from the gap 12 (or the drain hole 21 in FIG. 8 ) formed between the plate portion 6 and the plate 8.

The rainwater that has not flowed to the side flows toward the end of the vertical shaft 5, and is drained to the outside from the hole 18 of the side plate 3.

As for the rainwater that has fallen on the floor panel body 1 in this way, the final drainage of the floor panel body 1 itself is notched from the drainage grooves 9 on both sides of the floor panel body 1 and the ends of the vertical shafts 5. It flows from the portion 17 and the hole 18, respectively. Then, the subsequent rainwater is drained by the drainage means as shown in FIGS. 11 and 12.

That is, the rainwater that has fallen on the upper surface of the floor panel body 1 is discharged to the outside from the end portions on both sides of the vertical frame 2 as described above. This means that rainwater is drained inside the H-shaped steel 35 on the side plate 3 side of the floor panel body 1. Therefore, as shown in FIGS. 11 and 12, a gutter 51 having a substantially U-shaped cross section is bridged below the H-shaped steel 35 and between the columns 33. The gutter 51 is formed so as to descend from the center to both sides, and drains rainwater more smoothly. Further, since the gutter body 51 only drains rainwater, when it is made of metal, it is made thin so as to be light. Of course, the gutter body 51 may be formed of plastic or the like.

As shown in FIG. 11B, the width of the gutter body 51 is made larger than the width of the H-shaped steel 35 so as to receive all rainwater falling from the H-shaped steel 35. Also,
As shown in FIG. 12, drainage holes 52 are formed at both ends of the gutter body 51, and vertical gutters 53 for receiving rainwater drained from the drainage holes 52 are provided along the side surfaces of the columns 33.
Therefore, all the rainwater from the floor panel body 1 is received by the gutter body 51, the rainwater is drained from the drain hole 52 of the gutter body 51, and further, the rainwater is drained through the vertical gutter 53, or one of the three-dimensional parking lot. It is designed to drain into a drainage ditch on the floor.

The vertical gutter 53 may be formed of a general vertical gutter, or the rainwater from the gutter 51 may be drained by a rubber hose. When the rubber hose is used, unlike the downspout 53, it has elasticity and flexibility. Therefore, the position of the rainwater drainage port at the bottom of the rubber hose can be set on any side surface of the column 33.

Further, a hole is made in the side surface of the column 33 located at the end of the gutter body 51, and the gutter body 51 is inserted through the hole.
The rainwater drained at may be poured into the pillar 33. In this case, the pillar 33 is in the shape of a rectangular tube, and a drain hole is formed in the lower side surface of the pillar 33. Further, for example, hot-dip galvanizing is applied to the entire inner surface and outer surface of the pillar 33, whereby rust of the pillar 33 due to rainwater can be prevented.

Further, the shape of the gutter body 51 is not limited to a U-shaped cross section, but may be a substantially U-shaped cross section, a substantially semicircular cross section, a substantially V-shape, or the like. In short, any shape may be used as long as it can receive rainwater drained from the floor panel body 1.

Instead of using the gutter 51 shown in FIG. 12, H-shaped steel 35 shown in FIG. 18 may be used as a means for draining rainwater. That is, the horizontal width of the lower piece 55 of the H-shaped steel 35 is formed wider than the upper piece, and the bent piece 56 is formed by bending the end of the lower piece 55 upward over the entire length. The drain groove 57 is formed by the piece 55. In this embodiment, the floor panel body 1
The rainwater drained from the H-shaped steel 35 is received by the drainage groove 57, and the rainwater is made to flow to the pillar 33. At the end of the H-shaped steel 35, the rainwater is directly poured into the inside of the pillar 33. . Alternatively, the end of the H-shaped steel 35 may be connected to a downspout, a rubber hose or the like to allow rainwater to flow.

As a drainage method in the floor panel body 1, the height of the side plate 3 is made shorter than the height of the vertical frame 2, and the end of the L-shaped piece 14 is arranged above the vertical piece 13 of the vertical frame 2. The end of the drain groove 15 formed by the L-shaped piece 14 of the side plate 3 may be opened above the drain groove 9 of the vertical frame 2.
In this case, rainwater leaked from the vertical shaft 5 to the hole 18 of the side plate 3 without being drained is received by the drain groove 15 and drained to the drain groove 9 of the vertical frame 2. Further, without forming the holes 18, all the rainwater from the vertical shaft 5 is received by the drain groove 15 of the L-shaped piece 14 of the side plate 3, and the rainwater is drained from the drain groove 15 to the drain groove 9 of the vertical frame 2. It may be done.

By the way, as shown in FIG. 9, a caulking material or packing is laid to prevent rainwater from entering between the H-shaped steel 35 and the vertical frame 2 of the floor panel body 1. , It is designed to completely prevent the entry of rainwater. Even when the floor panel main bodies 1 are directly connected and fixed to each other, a caulking material or packing is laid between the floor panel main bodies 1 in the same manner as described above to completely prevent infiltration of rainwater. That is, as shown in FIG. 11A, when a plurality of floor panel main bodies 1 are laid, a cushioning material is interposed between the side surfaces of the floor panel main body 1, and above the cushioning material, the same as above. A caulking material or packing is laid on the to completely prevent the entry of rainwater.

As described above, the floor panel main body 1 is formed with the left and right vertical frames 2, the front and rear side plates 3, and the three horizontal and vertical bridges 4 and 5 which are bridged to the vertical frame 2 in the middle to form the frame main body 7. , This frame body 7
Is formed by covering a plurality of plates 8 on the upper surface thereof.
Each of the above members of the floor panel body 1 is made of steel, and each member is fixed by welding or the like, and after welding, for example, is plated by hot dip galvanizing. The same applies to the H-shaped steel 35 to be plated, but the floor panel body 1 is used as a floor panel on the second floor of a multi-storey parking lot, and is corroded by rainwater or the like to impair the appearance, This is to prevent the deterioration of strength with respect to the load of the automobile.

That is, first, the left and right vertical frames 2 and the front and rear side plates 3 are fixed to each other by welding in a rectangular frame shape, and then, as described above, the horizontal shaft 4, the vertical shaft 5, and the fixing brackets 19, 20 are vertically connected. It is fixed to the frame 2 and the like by welding. In this embodiment, the plate portions 6 of the vertical frames 2 on both sides and the two inner plates 8 are laid on the vertical shaft 5. Then, the respective members are welded and connected and fixed. The floor panel body 1 thus formed is immersed in a plating bath, and the entire floor panel body 1 is subjected to hot dip galvanizing.

In the pre-process of the plating process, in order to perform the plating process completely, the grease adhering to the member is removed and cleaning is performed to remove excess rust due to sulfuric acid or the like.
That is, a so-called degreasing step, pickling step, etc. are performed in the step before the plating process. By the way, for example, to construct a floor panel body, as shown in FIG. 19, a flat plate (iron plate) 58 is used as a plate, and the flat plate 58 is brought into surface contact with a casket 59 constituting a frame to perform welding. When the plating process is performed after performing the process, so-called non-plating is performed, the appearance is deteriorated, the commercial value is reduced, and further, it is necessary to always perform repair after the construction.

That is, when the upper surface of the cauldron 59 and the lower surface of the flat plate 58 are brought into surface contact and welded to each other to perform plating treatment, sulfuric acid in the pickling step, moisture in the atmosphere, and the like are brought into contact with the cauldron 59 and the flat plate 58. It gets in between by capillary phenomenon. Then, after the plating treatment, the acid-based water contained between the board 59 and the flat plate 58 comes out, and the surface is discolored or corroded.

Therefore, in the present embodiment, the frame main body 7 and the plate 8 are welded in a state of being in point contact or line contact without making surface contact, and in the plating treatment after welding,
The structure is designed so that acid or the like does not stay on the contact surface or can be easily washed with water or the like. That is, the vertical frames 2 and the side plates 3 on both sides of the floor panel body 1, the horizontal joints 4 and the vertical joints 5, the fixing fittings 19 and 20, the vertical frames 2 and the horizontal joints 4, and further the plate portion 6 and the plate 8 and the vertical frames. The contacts of the second grade are point or line contacts, respectively.

Further, when the bending pieces 10 and 11 are formed, the plate portion 6 and the plate 8 are not formed in a flat plate shape, but are formed in a substantially U-shaped cross section. The strength is also improved. Therefore, the floor panel body 1 having such a structure does not cause non-plating between the members even after the plating process, and also improves the strength of the plate portion 6 and the plate 8.

By the way, as a method of laying a floor panel on the second floor of a multi-storey car park, there is a so-called power flow method. FIG. 20 shows a laying method called this power flow. The plate 6 laid between the H-section steels 35 as a floor panel.
0 has a substantially U-shaped cross section, and one end of the plate 60 is L-shaped.
The mold connecting piece 61 and the U-shaped connecting piece 62 on the other end side. In this laying method, the connection piece 61 on one end side of the plate 60 is placed on the half of the upper surface of the H-shaped steel 35, and the connection pieces 61 of the adjacent plates 60 are placed in the U-shaped connection piece 62. And lay it down one after another.

In the laying method called this power flow, since the connecting piece 61 of the plate 60 is placed on the upper surface of the H-shaped steel 35, the upper surface of the H-shaped steel 35 is not used as a floor surface and is laid at the same intervals. However, the H-shaped steel 35 has a problem that the size of the plate 60 becomes large.

Therefore, in the present embodiment, the method of laying the floor panel body 1 on the upper surface of the H-section steel 35 is not adopted, but the H-section steel 35 is formed.
The floor panel main body 1 is disposed on the side of the floor panel main body 1 and the upper surface of the floor panel main body 1 and the upper surface of the H-shaped steel 35 are flush with each other. That is, as shown in FIGS. 9, 11, and 12,
The side surface of the H-shaped steel 35 is connected and fixed to the floor by the bolts 45 or the like, so that the upper surfaces of the plate portions 6 and 8 of the floor panel main body 1 and the upper surface of the H-shaped steel 35 are flush with each other. As a result, the upper surface of the H-section steel 35 can also be used as the floor surface, and the H-section steel 35 can be used as compared with the case of power flow.
If the distances are the same, the area of the floor panel body 1 itself can be reduced. Therefore, the weight of the floor panel body 1 itself can be reduced, and the multi-story parking lot can be made inexpensive in terms of cost.

By the way, as the measures for preventing the slipping of the tire of the automobile on the upper surface of the iron plate, those having unevenness have already been provided. However, the irregularities formed on the upper surfaces of these iron plates are merely formed for the purpose of preventing the slipping of the tire, and for example, there are continuous corrugated irregularities. In such a case, the unevenness is formed only to prevent slippage, and unlike the present invention, the unevenness is not used in combination with the floor panel on the second floor of the multi-storey parking lot and drainage of rainwater is taken into consideration.

That is, as shown in FIGS. 1, 2, and 5 to 8, patterns are formed on the upper surfaces of the plate portions 6 and the plates 8 of the floor panel main body 1, that is, unevenness is formed. 5 to 8 are enlarged views. Figure 5
In FIG. 8 of FIG. 8, for example, an elongated rib-shaped protrusion 63 having a substantially eight shape is provided on the upper surface of the plate 8, and a substantially circular convex portion is formed on both sides of the protrusion 63. 6
4 is projected. These two protrusions 63 and four protrusions 64 are continuously formed over the entire length of the plate 8 in the longitudinal direction. In addition, the vertical frames 2 on both sides of the floor panel body 1
Similarly, the upper surface of the plate portion 6 integrally formed with
And the convex portion 64 is formed. In addition, the pair of protrusions 63
May be formed alternately in opposite directions in the longitudinal direction of the plate portion 6 and the plate 8 . In addition, the convex portion 64
Is substantially circular, but it is needless to say that it may be formed into an elliptical shape or an elongated shape.

The protrusions 63 and the protrusions 64 formed on the plate 8 are formed, for example, by press working from above and below with two dies. As a forming method, for example,
There are squeezing processing and stringing processing, and the projection 63 and the like are formed by these drawing processing and stringing processing. As for the shape of the projection 63, the cross-sectional shape obtained by drawing out may be a substantially U-shape, or the cross-section may be formed into a substantially arcuate shape by drawing out, as shown in the figure. In the case of squeezing, the protrusion size of the protrusion 63 is set to
It is about half the thickness of the plate 8. When a plurality of plates 8 are laid, the protrusions 63 having a substantially eight shape are integrated with the protrusions 63 of the adjacent plates 8 to form zigzag unevenness as a whole, and the slip of the tire of the automobile is prevented. The function is enhanced. Furthermore, the strength of the plate 8 is also increased by the elongated rib-shaped protrusions 63.

Further, since the projections 63 and the projections 64 are not continuous wave-shaped irregularities but are formed separately, they do not interfere with drainage of rainwater, for example, rainwater that vigorously falls, The elongated protrusion 63 serves as a guide,
It has a role of smoothly guiding to the gap 12. Further, due to the projection 63 and the convex portion 64, even if rainwater is on the upper surface of the plate 8, it is difficult for water to splash by the tire, and
Even when walking, the shoe does not splash on the protrusion 63 and the protrusion 64 to splash water.

In the above case, the case where the upper surfaces of the plate portion 6 and the plate 8 are flat has been described.
By descending from the center of the plate 8 in the width direction to both sides over the entire length, that is, by forming the cross section of the upper surface of the plate 8 in the width direction into a substantially V shape, the plate 8 descends to the upper surface. The rainwater can be drained more smoothly without being retained on the upper surface. The inclination angle of the inclined surface of the plate 8 is set so that the user does not feel that the plate 8 is not inclined, because the rainwater is simply poured. As a result, the user does not feel anxious that the upper surface of the plate 8 is inclined. Further, in this case, the elongated rib-shaped projection 63 serves as a guide to smoothly guide the rainwater to the gap 12 and the drain hole 21. Furthermore, the upper surface of the plate portion 6 of the vertical frame 2 may be slightly inclined toward the plate 8 side.

The above matters have been described for the case of a two-story multistory parking lot, but the present invention is not limited to the case of a two-story multistory parking lot and the present invention can be applied to a multistory parking lot of three or more stories. It is applicable. Further, it goes without saying that the present invention can be applied to not only a self-propelled multi-storey parking lot but also any type of multi-storey parking lot.

[0088]

According to the present invention, the rainwater that has fallen on the floor panel body on the upper floor of the multi-storey parking lot flows down to the vertical shaft through the first drainage means, and the rainwater from the vertical shaft is discharged to the second vertical shaft. It is received by the drainage means, and further flows through the third drainage means provided on the lower surface side of the H-shaped steel and the fourth drainage means to the ground, drainage grooves formed on the ground, and the like. Rainwater that has fallen on the upper surface of the floor panel body can be efficiently drained. Therefore, rainwater will not leak to the floors below the floor panel body. Therefore, a person who parks a car on the lower floor and gets on and off does not get rainwater and does not feel uncomfortable. Further, the floor panel main body is formed by a plate portion integrally formed with the vertical frame and a plurality of plate-shaped plates so that the floor surface is closed, and is constituted by a conventional net body that allows the floor above to be seen from below. Unlike the floor panel itself, you cannot see the upper floors from the bottom, which gives a sense of security, especially for women.

Further, according to the second aspect, as the first drainage means, a gap is formed between the plate portions of the vertical frame and between the plates, and substantially the entire length in the longitudinal direction. Rainwater that has fallen on the upper surface of the floor panel main body can be efficiently drained to the vertical shaft via the.

Further, in the present invention, the plate portion of the vertical frame and the end portion of the plate are bent substantially L-shaped over substantially the entire length in the longitudinal direction, and the gap between the bent pieces is formed. Since the rainwater is drained from the vertical shaft to the vertical shaft, the rainwater that has fallen on the upper surface of the floor panel main body can be efficiently drained to the vertical shaft through this gap, and the bent portion causes the plate portion to drop. Also, the strength of the plate can be improved.

According to a fourth aspect of the present invention, as the first drainage means, the plate portions of the vertical frame and the end faces of the plates are brought into contact with each other, and the end portions of the plate portions and the plate on the contact surface side are brought into contact with each other. Since a plurality of drainage holes are formed along the longitudinal direction at predetermined intervals, rainwater can be efficiently flowed vertically through the drainage holes while keeping the strength of the plate portion and the plate of the floor panel body constant. Can be washed away.

Further, in the present invention, as the second drainage means, a hole is formed at the side plate located at the end of the vertical shaft, and the rainwater is discharged from the vertical shaft through this hole. Therefore, rainwater flowing vertically through the holes in the side plates can be efficiently discharged to the outside.

Further, in the present invention, drain grooves are integrally formed inside the lower portions of the left and right vertical frames constituting the floor panel main body, and the horizontal caverns located above the drain grooves of the vertical frames are opened at the upper surface. As a shape, the end of the horizontal shaft is opened to the drain groove side of the vertical frame, a hole for draining is formed in the bottom of the vertical shaft located above the horizontal shaft, and the rainwater that has dropped from the hole is drained horizontally. In addition, by draining water through the drains of the vertical frame, the rainwater that has flowed down the vertical shaft can be drained from the horizontal shaft to the drains of the vertical frame through the vertical shaft itself and the holes formed in the vertical shaft. The two drainage routes will be formed, and rainwater can be drained efficiently.

Further, in claim 7, the contact between the respective members of the vertical frame, the plate, the vertical shaft, the horizontal shaft and the side plate is point contact or line contact, and the entire floor panel main body in which the respective members are fixed by welding is used. Since it is plated, compared to the case where the entire floor panel main body, which is made by welding the members by making surface contact with each other, is plated, each member is point-contacted or line-contacted. It is possible to prevent the discoloration due to non-plating and the occurrence of rust, so that the appearance is not damaged, the product value is not deteriorated, and the repair is not required after the construction. In addition, it is possible to easily carry out washing or the like later.

In the eighth aspect, the floor panel main body is arranged in the inner space of the H-shaped steel, and the upper surface of the floor panel main body and the upper surface of the H-shaped steel are laid substantially flush with each other. The upper surface of the H-shaped steel is also used as the floor surface in the same manner as the upper surface of the plate, and the area of the floor panel main body is smaller if the H-shaped steels are arranged at the same intervals as compared with the case of so-called power flow. It is possible to reduce the weight of the floor panel body. Therefore, the cost of the floor panel body can be reduced.

In the ninth aspect, since the third drainage means is a gutter having an open upper surface,
It can receive all the rainwater drained from the floor panel body, does not leak the rainwater, and the structure of the gutter body has an open top surface, so that the gutter body can be easily manufactured.

Further, in claim 10, since the drainage groove is integrally formed in the H-shaped steel as the third drainage means, it is not necessary to additionally attach a gutter body for receiving rainwater from the floor panel main body. The construction can be simplified and the cost can be kept low.

In the eleventh aspect, since the fourth drainage means is a vertical gutter attached along the side surface of the pillar, a general downspout can be used as the downspout. Can be constructed at low cost, and does not impair the appearance.

In the twelfth aspect, the fourth drainage means is a hose provided along the side surface of the column and having elasticity and flexibility, so that the drainage port of the hose is arranged on any side surface of the column. It can be installed, and can respond flexibly according to the construction site. Also, the cost can be reduced,
Construction is also easy.

In the thirteenth aspect, since the fourth drainage means is provided inside the cylindrical column, the drainage device is not attached to the outer surface of the column, so that the drainage device is an obstacle. There is no need to reduce the space in the parking lot and it is easy to move in and out of the car. In addition, the appearance of the drainage device is not damaged as compared with the case where the drainage device is provided on the outer surface of the pillar.

In the fourteenth aspect of the present invention, the plate portion of the vertical frame and the upper surface of the plate are formed with projections in a substantially eight shape at predetermined intervals over the entire length in the longitudinal direction. Therefore, a plurality of plates are laid. In this case, the protrusions have a continuous zigzag pattern, so that the slip of the tire of the automobile can be more completely prevented, and the protrusions can also increase the strength of the plate itself. Moreover, the projections provided on the upper surface of the plate reduce splashes of rainwater when the vehicle is running, and also reduce splashes of rainwater when a person walks. Furthermore, the projections of the rainwater that has been vigorously falling can serve as a guide, and the rainwater can be smoothly drained.

According to the fifteenth aspect, since the upper surface of the plate is an inclined surface that descends from the substantially central portion to both sides, rainwater that has fallen on the upper surface of the plate can be smoothly drained through the inclined surface. Therefore, the rainwater is not retained on the upper surface of the floor panel body, and the user of the parking lot does not feel uncomfortable due to the retention of the rainwater.
