Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a continuous inclined floor type self-propelled multi-story parking garage having a structure in which a parking space is provided along a lane that is spirally continuous in the vertical direction. It relates to the floor structure.

[Background Art] There is a continuous inclined floor type self-propelled multi-story parking lot as a parking lot constructed in a large city and surrounding cities. This is basically a structure in which an inclined furnace is provided between each of the multi-story floors.
The vehicle has a structure in which a vehicle path is spirally continued in the vertical direction so as to ascend and descend the height of the floor, and a parking space is provided along the vehicle path.

In general, a building with a continuous inclined floor type self-propelled multi-story parking garage generally has a steel frame and a floor slab made of reinforced concrete. And in the case of reinforced concrete construction in this way, after forming a frame for floor slab on the steel beam and the steel beam that is the frame, giving the necessary reinforcement, then placing concrete Forming a floor slab. This concrete floor slab is constructed so that the floor is connected to each layer and each floor continuously with a gentle slope.

"Problems to be Solved by the Invention" However, in such a conventional continuous inclined floor type self-propelled multi-story parking garage, the floor slab is continuously and continuously provided between each floor as described above. Due to the structure connected in an inclined manner, water flows along the surface of the continuous inclined floor slab, for example, when rainwater enters or when water is sprayed for cleaning each floor, and this water flow is generated on the lower floor. There was a problem that the concentration increased intensively and reached the lowest floor. In particular, in this type of parking lot, the exterior wall of the building is often removed or made open for the purpose of opening feeling and cost reduction, etc., so that rainwater easily penetrates, and this point also increases the above-mentioned problem. There was a problem.

On the other hand, considering the seismic shear force input to the building as an external force, the layer shear force for each floor is unclear due to the continuous slope type, and the entire building including the seismic design is therefore unclear. There is also a problem that the analysis required in the structural design becomes extremely complicated and difficult.

Further, since the floor slabs having a function of transmitting to the seismic elements such as braces are continuous over each floor in this way, the axial force or the like generated on the floor slabs may be added to all floors of the building. In such a case, it is expected that the degree of stress concentration will inevitably increase. Therefore, as a countermeasure, it is necessary to increase the thickness of the floor slab in advance, and also to increase the section of the seismic element. There was also a problem that there is.

[Means for Solving the Problems] In order to achieve the above object, the present invention is directed to a vehicle that is spirally connected to a vertical direction so as to ascend and descend a height of one floor by a 360-degree turning. In a continuous inclined floor type self-propelled multi-story parking lot provided with a parking space, a floor slab that forms the lane and the parking space on each floor is provided with a groove extending in the width direction of the floor slab over the entire width. A floor structure in which a drain port is provided in the groove and a water-permeable lid is provided in the groove. Here, it is desirable that the groove is formed at a depth greater than the thickness of the floor slab.

[Operation] In the present invention, a groove extending in the width direction of the floor slab is provided on the floor slab that forms the lane and the parking space of each floor of the continuous inclined floor type self-propelled multi-story parking garage over the entire width. By providing a drain structure in the ditch and a floor structure with a water-permeable lid, rainwater that has penetrated into the building and water that is sprayed during floor washing and drained from the floor slab surface can be drained. It can be performed effectively for each floor.

Since the groove is provided with a lid, the running of the vehicle is not hindered.

If this groove is provided deeper than the thickness of the floor slab,
A discontinuity is created in the floor slab, which has the effect of clarifying the layer shear force on each floor. As a result, it is possible to rationally determine the cross section of the floor slab having the function of transmitting the data to the seismic element and the brace of the seismic element. By clarifying the layer shearing force, the stress state of the entire structure can be stabilized.

Embodiment An embodiment of the present invention will be described below in detail with reference to FIGS. 1 to 4.

FIG. 1 is a perspective view showing a floor structure of a reference floor of a self-propelled multi-story parking garage according to the present invention. FIG. 2 is a plan view of a reference floor.

In the figure, reference numeral 1 denotes a lane, which is raised and lowered by one floor by 360 ° turning. The lane 1 has a pair of opposed inclined plane straight sections having inner and outer routes formed at substantially equal slopes and a pair of opposed inclined planes having inner and outer routes formed at unequal slopes. The rectilinear portion and four corner portions each having an inclined curved surface for matching the inclination of each of the rectilinear portions are formed so as to turn in a rectangular shape. A parking space 2 is provided along a lane 1 that is spirally continuous with the vertical direction. 3 is an outside parking area, and 4 is an inside parking area. Reference numeral 5 denotes a corner portion, and reference numeral 6 denotes a line indicating a traveling section of the lane 1. 7 is a partition, 8 is an elevator room,
9 is an emergency staircase.

Reference numeral 10 denotes a floor slab that forms a lane 1 and a parking space 2 on each floor. In this embodiment, as shown in FIG. 1 and FIG. 2, of the floor slab 10, the lane 1 is traversed on a part where there is a substantially flat inclined lane. The groove 11 extending in the width direction of the floor slab 10 has a full width AB
Is provided over. In this embodiment, the groove 11 is a single elongated groove.

FIG. 3 is a sectional view showing a specific structure of the groove 11 provided in the floor slab 10. As shown in FIG. FIG. 4 is a plan view of FIG. In the drawing, reference numeral 12 denotes a steel beam (small beam), and reference numerals 13 and 14 denote angle irons for receiving a formwork for cast-in-place concrete for the bottom slab. The floor slab 10 is provided with a groove 11 deeper than the thickness of the floor slab as shown in the figure, thereby creating a stress discontinuity in the floor slab. At least one drain port (not shown) is provided at the bottom of the groove, and is configured to drain water to the outside through a gutter. And the said groove | channel and a drain port are normally provided for every floor. At the upper end of the groove 11, steps are formed along the groove 11, and an L-shaped steel plate 15 is anchored to these steps.
16 is firmly attached to the floor slab 10. And
These steps have lids 17 such as gratings and steel grid frames.
Is placed. Waterproof mortar 18 is applied to the bottom of the groove. The floor slab 10 has a large thickness near the groove of the steel beam 12. 19 is a lath and 20 is a refractory coating.

In the continuous inclined floor type self-propelled multi-story parking lot of the above structure,
The water flowing along the surface of the inclined floor slab, such as when rainwater enters the building or when water is sprayed for cleaning each floor,
The water flows into a groove 11 provided over the entire width of the floor slab 10, and is discharged to the outside through a drainage port at the bottom of the groove.
Usually, this drainage port is provided for each floor, so that the flowing water is drained for each floor. Therefore, there is no problem such that the height increases intensively from the upper floor to the lower floor along the surface of the continuously inclined floor slab and reaches the lowest floor.

Since the lid is provided on the above-mentioned groove, it does not hinder the running of the car.

Further, the depth of the groove 11 is provided deeper than the thickness of the floor slab 10, and by providing a discontinuous portion in the floor slab 10, the layer shearing force of each floor is independent for each floor. Become
Therefore, the layer shearing force for each floor becomes clear. The clarification of the layer shear forces on each floor greatly simplifies the analysis required for the structural design of the entire building, including the unclear seismic design due to the continuous slope. And since there is no fear that the axial force and the like generated on the floor slab having a function of transmitting to the seismic element such as the brace are added to each floor as in the conventional case, the thickness of the floor slab is increased more than necessary. Further, there is an advantage that it is not necessary to enlarge the section of the member of the earthquake-resistant element.

 FIG. 5 is a sectional view showing a second embodiment of the present invention.

In this embodiment, the groove 11 is constituted by a steel groove frame 21 and the floor slab 10 is divided by the groove frame 21. The steel grooved frame 21 is attached to the flange of the steel beam (small beam) 12 on the lower side of the lane, and also serves as a cast-in-place concrete floor slab to be cast thereafter. . The inner wall of the steel groove frame 21 is coated with a waterproof coating. A U-shaped notch is provided at the end of the upper surface of the groove 11 to form a wide width, and the L-shaped steel plate 15 is firmly attached to the floor slab 10 by the anchor 16. A lid 17 such as a grating or a steel grid frame is placed on the step formed at the end of the upper surface of the second embodiment, which is the same as the previous embodiment.

In addition, the drainage effect of the water flow flowing along the floor surface such as rainwater intrusion into the building of the continuous inclined floor type self-propelled multi-story parking garage of this structure and water sprinkling for each floor washing, earthquake and wind etc. The operation and effect when the external force is applied are almost the same as those in the first embodiment, and therefore the description thereof is omitted.

FIG. 7 is a view showing a third embodiment of the present invention. In this embodiment, the floor slab 10 is divided. Both floors
On the lower surface of 10, a grooved frame 22 made of a thin steel plate has a fastener 23 such as a bolt.
It is fixed at.

The structure of the upper end of the groove 11 is exactly the same as in the first and second embodiments. Although the basic operation and effect of this embodiment are almost the same as those of the first and second embodiments, in this case, the groove frame 22 is attached to both floor slabs 10.
Since it is only necessary to attach it to the lower side of the groove frame, the work is very easy, and the material cost of the groove frame 22 can be reduced. Further, the depth of the groove 11 can be easily changed only by changing the depth of the groove frame 22.

Further, since the floor slab 10 is completely divided, the layer shearing force for each floor becomes clearer than in the first and second embodiments.

FIG. 8 is a view showing a fourth embodiment of the present invention. In this embodiment, the groove 11 of the floor slab 10 is formed by a steel groove frame 21,
This steel groove frame 21 is stretched between the steel beam 12 and the flange.
Connected at 24. The structure of the upper end of the groove 11 is the first to third
This is exactly the same as the embodiment. With this configuration,
Since the concrete above and below the elastic member 24 is substantially cut off by the elastic member 24, the effect of the structure of this embodiment when an external force such as an earthquake or wind is applied to the building having the structure of this embodiment Is almost the same as that of the second embodiment.

Although the grooves of the full width of the floor slab in the first and fourth embodiments are straight in a plan view, it is needless to say that the grooves may be jagged, though not particularly shown.

[Effect of the Invention] As described in detail above, the inclined floor type self-propelled multi-story parking garage according to the present invention is spirally continuous in the vertical direction so as to ascend and descend the height of one floor by turning 360 °. In a sloping-type self-propelled multi-story parking garage having a parking space provided along a lane to be extended, the floor slab forming the lane and the parking space on each floor extends in the width direction of the slab. Since the groove is provided over the entire width, a drain port is provided in the groove, and a water-permeable lid is provided in the groove, the inclined floor slab such as rainwater or water for cleaning each floor which has entered the building is provided. The water flowing along the surface of the floor can be efficiently drained to the outside for each floor.

Further, when the groove is provided deeper than the thickness of the floor slab, a discontinuous portion is formed in the floor slab, and a layer shearing force due to an external force such as an earthquake or wind becomes clear for each floor. The overall structural design can be simplified to the same extent as a general building. Further, the cross section of the floor slab and the brace or the like as the earthquake-resistant element can be determined rationally, and there is an excellent effect that the stress state of the entire structure can be stabilized.
