Abstract

PURPOSE:To obtain a structure wherein noise and slippage occurs at low levels during the running of a car in a multistory parking space including a frame of steel materials. CONSTITUTION:Steel materials are used to form a frame 6 of parking floors 2, 3 and a sloped running track 4, and a large number of standardized concrete floor boards 10 are arranged on the frame 6 to form a floor surface and a running surface. The concrete floor board 10 has a damping property for vibration, and hence noise is restrained from occurring. And by making rough the surfaces of the boards 10 of the track or by forming a groove-like pattern 21 thereon, frictional forces on the surface of the running track is increased thereby to prevent slippage of a car.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple multistory parking lot having a steel frame.

[0002]

2. Description of the Related Art A simple multi-storey parking lot is known in which a single-story or multi-story parking floor is formed by steel frames, and the parking floors are connected by slope runs.

In this multi-level parking lot, a frame of a parking floor and a slope runway, which are vertically stacked by steel columns and beams, is constructed and a floor board is attached to the frame to form a floor surface and a runway surface. As the floor plate, a metal plate obtained by subjecting punched metal, expanded metal or the like to rust prevention is used.

[0004]

However, such metal floor boards are connected to each other by using bolts or the like,
Although it is attached to the skeleton, when the vehicle runs on the floor plate, there is a problem that an impact sound at the connecting portion and a resonance sound of the floor plate itself are likely to be generated, which becomes a large noise source.

Further, although a metal floor plate is provided with anti-slip measures such as punching, since the metal surface itself is slippery, the vehicle tends to slip. In particular, when the floor board gets wet due to rain or the like on an inclined sleep runway, there is a problem that the frictional resistance on the surface of the floor board decreases and slipping easily occurs.

Furthermore, the metal surface of the floorboard is subjected to various anticorrosion treatments such as galvanization, but the metal surface subjected to these treatments easily reflects light, and the reflected light is bad for the surrounding environment. There were also defects that affected it.

[0007] Therefore, an object of the present invention is to solve the above-mentioned conventional problems, and to provide a multi-story parking lot which is low in noise, excellent in slip prevention performance, and easy to construct. .

[0008]

In order to solve the above-mentioned problems, the present invention forms a single-layer or multiple-layer parking floor and a slope runway connecting between the parking floors with a steel frame. In a multi-storey car park, the floorboards of each parking floor and slope runway were formed by a plurality of standardized concrete slabs.

The second means of the present invention employs a structure in which the surface shape of the concrete floor slab is partially different between the parking floor and the slope runway.

In each of the above structures, a groove pattern may be provided on a part of the surface of the concrete floor slab.

[0011]

As described above, when the floor board is formed of a concrete floor slab, the concrete has a function of attenuating vibrations, and the floor board itself does not easily become a resonator, so the sound generated when the vehicle runs on it is reduced. However, noise is suppressed.

Further, since the surface of the concrete has a large surface roughness and the entire surface has irregularities, the frictional resistance between the surface of the concrete and the tire of the vehicle is large, and slip can be prevented. Further, since the concrete surface has a smaller light reflectance than the metal surface, the influence of the reflected light can be reduced.

Further, as in the second means, the surface shape of the concrete floor slab is formed so as to have a larger frictional resistance in a portion such as a running path or a slope running path on the parking floor where slipping is likely to occur. It is possible to more effectively prevent slipping during traveling of the vehicle.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 2, the multi-storey parking lot of this embodiment has a two-story structure, and two parking floors 2 stacked on the ground floor parking floor 1 at predetermined intervals.

5 constructs a frame 6 by combining a large number of steel columns 7 and beams 8 and 9 on the basement floor 1, and installs a large number of concrete floor slabs 10 between the beams 8 and 9 of the frame 6. It is formed by mounting.

As shown in FIG. 3, the concrete floor slab 10 is a precast plate (PC plate) in which stress is introduced by pre-tensioning and post-tensioning. It is formed by embedding the braided reinforcing bar 12.

The concrete floor slab 10 is formed in a rectangular shape having a rated size by a mold for concrete molding. As shown in FIG. 2, the beam 8 and the beam 9 of the skeleton 6 are formed.
Several floor slabs 10 can be mounted side by side in the gap formed between the floors.

Further, as shown in FIG. 3, a plurality of recesses 13 are formed in the side portion of the concrete floor slab 10 at predetermined intervals, and joint fittings 14 are attached to the respective recesses 13. .

This joint fitting 14 is shown in FIGS.
As shown in, the bottom plate 15 and the three side plates 16 are formed. The side plates 16 on both sides of the bottom plate 15 are embedded in the concrete of the concrete floor slab 10 and are fixed to the tips of the reinforcing bars 12. Further, elongated bolt-shaped bolt holes 17 and 18 are formed on the floor plate 15 and the front side surface 16, respectively.

In order to mount the concrete floor slab 10 and the skeleton 6 using this joint fitting 14, as shown in FIG. The bottom plate 15 is fastened and fixed with bolts 19. Further, the side plates 16, 16 of the butted joint fittings 14, 14 are fastened with bolts 19 to connect the floor slabs 10 to each other, and then the recess 13 is filled with mortar or the like to be integrated.

On the other hand, on the side surface of the floor slab 10 which is not connected to the beams 8 and 9 of the frame 6, the side plates 16 of the joint fittings 14 and 14 abutted to each other as shown in FIG. Fill with mortar etc. and connect.

In the embodiment of the multi-story parking lot having the above structure, the beams 8 and 9 of the steel frame 6 as shown in FIG.
In the meantime, a number of concrete floor slabs 10 are arranged to form parking floors 2 and 3 and slope runs 4 and 5, and a car stop 20 or the like is attached to the floor slabs 10 at predetermined positions on the parking floors 2 and 3 to provide a parking space. Form.

In addition, the surface of the concrete floor slab 10 on the sloped roads 4 and 5 and the running roads of the parking floors 2 and 3 is formed with a rough surface having large irregularities, or various groove patterns 21 are formed. Increase the frictional resistance of the surface. As a result, slipping of the vehicle traveling on the track can be effectively prevented, and safe traveling of the vehicle can be guaranteed. Such surface roughening of the floor slab and formation of a groove pattern can be easily performed by changing the shape of the concrete formwork for molding the floor slab, and can be easily adapted to mass production.

In the multi-storey parking lot of the above embodiment, the concrete forming the concrete floor slab 10 is a vibration-proof material and has a function of damping vibrations. The sound generated from
Generation of noise is suppressed.

Further, since the concrete surface does not have the gloss like a metal surface and the reflectance of light is small, the influence of the reflected light on the surroundings can be significantly reduced.

In addition, since the concrete floor slab 10 is easy to mold and can be mass-produced, it can be supplied at a low price and the parking lot can be manufactured at a low cost.
