Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to a non-slip concrete surface.

[0002]

2. Description of the Related Art In a three-dimensional parking lot for automobiles, a plurality of parking floors are formed, and these parking floors are connected to each other through an inclined road. On this sloping road, the tires of automobiles are slippery and the tires are often slipped. For this reason, the surface of the concrete on the sloped road is roughened, or small irregularities are formed on this surface,
It sometimes prevented the tires from slipping.

[0003]

However, when the surface of concrete is roughened or small irregularities are formed on this surface, there is a problem that the running noise of the automobile, that is, the noise generated between the tire and the concrete becomes large. .

Therefore, an object of the present invention is to provide a non-slip concrete surface which can reduce the running noise of an automobile while improving the anti-slip action.

[0005]

In order to solve the above-mentioned problems, the concrete surface of the present invention has a non-slip surface in which a plurality of non-slip chips made of synthetic rubber or synthetic resin are superposed on the surface of the concrete. Non-slip chips are half-embedded in the concrete surface.

[0006]

According to the present invention, a plurality of anti-slip chips made of synthetic rubber or synthetic resin are half-buried in the surface layer of concrete. Therefore, on the surface of this concrete, each slip stopper chip and the surface of the concrete are mixed. These anti-slip tips increase the friction on the concrete surface and thus serve as a non-slip agent. Further, since these anti-slip chips are made of synthetic rubber or synthetic resin, they have flexibility. Therefore, even if an automobile runs on this concrete, a large amount of noise does not occur.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The non-slip concrete surface of this embodiment is applied to the floor of a multi-storey parking lot as shown in FIG. 1, for example. This multi-storey car park has a three-story structure, and a parking floor 1 on the ground floor, a parking floor 2 on the second floor, a parking floor 3 on the third floor, and a sloped track connecting the parking floors 1 and 2 4 and a sloped track 5 that connects the parking floors 2 and 3 to each other.

Each parking floor 2, 3 and each sloped road 4, 5
Builds a skeleton 6 by combining a large number of steel columns 7 and beams 8 and 9 on the parking floor 1 on the ground floor, and installs a large number of concrete floor slabs 10 between the beams 8 and 9. It becomes.

As the concrete floor slab 10, a precast plate (PC plate) in which stress is introduced by pre-tension and post-tension is used as shown in FIG. 2, and reinforcing bars are knitted longitudinally and laterally inside the concrete layer 11. Arrangement 1
It is the one that embedded 2.

This concrete floor slab 10 is provided with a non-slip surface for the concrete surface of this embodiment, and has the features of the present invention.

That is, as shown in FIG. 2, a plurality of synthetic rubber pieces 13 are arranged and superposed on the surface of the concrete floor slab 10, and as shown in FIG. The piece 13 is partially buried.
Anchor pins 14 are provided so as to project from the back surface of the synthetic rubber pieces 13.
4 deeply sinks into the concrete slab 10. The respective synthetic rubber pieces 13 are firmly fixed by these anchor pins 14.

Therefore, on the surface of the concrete floor slab 10, each synthetic rubber piece 13 and the concrete surface are mixed.

The concrete floor slab 10 is formed using a mold for concrete molding. In the mold, the synthetic rubber pieces 13 are pressure-bonded to the surface of the concrete floor slab 10, and the synthetic rubber pieces 13 are partially buried.
In addition, this formwork enables the concrete floor slab 10
Is formed into a rectangle with the rated dimensions. As shown in FIG. 4, several rectangular floor slabs 10 are attached between the beams 8 and 9 of the frame 6.

As shown in FIG. 2, a plurality of recesses 15 are formed on the side piece of the concrete floor slab 10 at predetermined intervals. Joint fittings 16 in these recesses 15
Is attached.

As shown in FIGS. 5 and 6, the joint fitting 16 is formed of a bottom plate 17 and three side plates 18, and the side plates 18 on both sides are embedded in the concrete of the concrete floor slab 10 to form the reinforcing bar 12 It is fixed to the tip.
Further, elongated bolt holes 19 and 20 are formed in the bottom plate 17 and the front side plate 18.

In order to attach the concrete floor slab 10 to the skeleton 6 using the joint fittings 16, as shown in FIG. 7, each of the joint fittings 16 and 1 is mounted on the beam 8 of the skeleton 6.
6 bottom plates 17, 17 are placed on the beam 8 and the bottom plates 17, 1
7 are fastened and fixed by respective bolts 21 and 21. Also, each butted joint fitting 16, 16
The side plates 18, 18 are fastened with respective bolts 21, 21 to connect the floor slabs 10, 10 on both sides to each other, and then the recesses 15, 15 are filled with mortar to be integrated.

Also, with each concrete floor slab 10 alone,
Connect with each other. As shown in FIG. 8, each joint fitting 1
The side plates 18, 18 of 6, 16 are fastened with bolts 21 to connect the floor slabs 10, 10 on both sides to each other, and the recesses 15, 1,
Fill 5 with mortar.

As described above, in the multi-storey parking lot, the sloped roads 4 and 5 and the parking floors 2 and 3 are formed by the concrete floor slabs 10.
As described above, the synthetic rubber pieces 13 are arranged on the surface of the. When an automobile runs on these concrete floor slabs 10, these concrete floor slabs 10
Since a large amount of friction is generated between the large number of synthetic rubber pieces 13 and the tire of the automobile, slipping and idling of the tire of the automobile are prevented. Since the increase in friction due to these synthetic rubber pieces 13 depends on the material and surface shape of these synthetic rubber pieces 13, it is necessary to appropriately determine the material and surface shape. Alternatively, the arrangement of the synthetic rubber pieces 13 on the concrete floor slab 10 may be devised to make it more slippery.

Further, since the synthetic rubber piece 13 has elasticity, it reduces the impact between the tire of the automobile and the concrete floor slab 10. This reduces the running noise of the car,
Helps prevent noise pollution.

On the other hand, since the concrete floor slab 10 is molded in the mold as described above, it is suitable for mass production and can be provided at a low price. It also enables the production cost of parking lots to be kept low.

In this embodiment, the synthetic rubber piece is exemplified, but the invention is not limited to this and a synthetic resin piece may be used. Further, the shapes and sizes of the synthetic rubber pieces and the synthetic resin pieces may be appropriately determined. Further, a groove may be formed on the outer periphery of the synthetic rubber piece or the synthetic resin piece to make it difficult to separate from the concrete.

Although a concrete floorboard made of a precast plate is exemplified here, the slip stopper of the present invention can be applied to the surface of any kind of concrete.

Furthermore, the present invention can be applied not only to the floor of the parking lot, but also to any place as long as slipperiness and low noise are required.

[0025]

As described above, according to the present invention, each surface of the concrete is mixed with the slip preventing chips and the surface of the concrete. These anti-slip tips increase the friction on the concrete surface and thus serve as a non-slip agent. Further, since these anti-slip chips are made of synthetic rubber or synthetic resin, they have flexibility. Therefore, even if an automobile runs on this concrete, a large amount of noise does not occur.
