Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a car stopper block installed on the concrete floor of a parking lot, and is particularly suitable for installation on a floor with a waterproof layer, such as on a rooftop.

[Conventional technology]

BACKGROUND ART Concrete car stop blocks are known that are installed on the concrete floor of a parking lot to catch the rear wheels of a car when it backs up, and prevent the car from rolling back further to prevent accidents.

[Problem that the invention attempts to solve]

The above-mentioned known car stop blocks are generally only fixed on the concrete floor with mortar or adhesive, and if the car backs up violently and the wheels collide with the blocks, the blocks will break away from the concrete floor. It may peel off.

In order to eliminate this problem, it is recommended to drill holes in the floor and install bolts, and use these bolts to secure the block, but it is said that drilling holes in floors that have a waterproof layer on the roof of a building will impair the waterproofing effect. There's a problem.

[Means for solving problems]

In order to solve the above problems, this invention has a wheel bearing surface in a cross section in the front-rear direction, which has a concave arc shape in which the front part is low and gradually becomes higher towards the rear.
The cross section in the left and right direction is formed horizontally, and the front part is made thinner and the rear part thicker, so that the difference in height between the front part and the rear part is considerably lower than the radius of the wheel. The rear part is designed to prevent the wheels from moving backwards when the wheel rests on the wheel receiving surface, and the front and rear surfaces are sloped with the upper part retracted, so that there are no obstacles such as bolts that could damage the waterproof layer on the floor. To provide a car stopper block that can be fixed to a floor surface without using anything.

〔Example〕

1 is a car stop block of this invention, made of reinforced concrete. This block 1 has a thin wall thickness at the front part 2 and a thick wall thickness at the rear part 3.

In addition, the upper wheel bearing surface 4 is a recessed arc-shaped surface that is low at the front and gradually becomes higher toward the rear when viewed in the front-rear cross section as shown in Figure 1, and in the left-right cross section. It is horizontal in all parts.

Further, the upper end face 5 of the rear part 3 is a horizontal plane, and the front face 6 of the front part 2 and the rear face 7 of the rear part 3 are slopes with the upper part recessed.

The dimensions of the above embodiment are as follows: The bottom surface of the block 1 is a rectangle measuring 410 mm in the front-rear direction and 500 mm in the left-right direction, the height of the front surface 6 is 50 mm, the upper end is a slope recessed by 10 mm from the vertical plane, and the height of the rear surface 7 is 50 mm. is 170 mm and the upper end is a slope retracted 15 mm from the vertical plane, and the width of the upper surface 5 in the front and back direction is 85 mm.
mm. Therefore, the height difference between the front and rear parts is
It will be 120mm. This value is suitable for a wheel with a diameter of approximately 600 mm, is considerably lower than the radius of the wheel of 300 mm, and is at a height that allows the rear part to prevent the wheel from moving backward when the wheel rests on the bearing surface 4. However, it goes without saying that this value varies within a certain range depending on the size of the wheel.

FIG. 1 shows a block 1 of this invention fixed on a concrete floor 9 provided with a waterproof layer 8.

That is, after the block 1 of this invention is placed on a predetermined location on the waterproof layer 8, a known asphalt pavement 10 is applied.

The above pavement 10 has a thickness such that its upper surface is equal to the upper surface of the front section 2.

In some cases, a block of this invention is placed on a concrete floor surface that does not have a waterproof layer, and then asphalt is applied to the concrete surface.

〔effect〕

The car stopper block of this invention is made of concrete, and its upper surface is a concave arc surface, and the height difference between the front and rear parts is 120 mm, which is considerably lower than the radius of the wheel. The rear part is set at a height that can prevent the wheel from moving backward when the wheel rests on the wheel receiving surface, so when the wheel is placed on the wheel, the center of the wheel is considerably above the rear part of the wheel stopper block of this invention. Most of the force acting on the stopper block is directed downward, preventing the wheels from moving backwards, and since the block is made of heavy concrete, there is little risk of the block shifting backwards.

Therefore, the car stop block of this invention only needs to be placed on a concrete floor or a concrete floor that has a waterproof layer, and since it does not cause any damage to the concrete floor, it can be used as a waterproof barrier against rainwater, such as on multi-story parking garages or the rooftops of various buildings. It can be installed even on treated floors without worrying about the possibility of water leakage. In addition, the front and rear surfaces of the blocks are sloped, and the asphalt pavement is in contact with these slopes, which prevents the blocks from floating, so the blocks are stable without the use of bolts or the like, compared to the conventional method of simply gluing. fixed more firmly than others.

Furthermore, since the car's wheels rest completely on the wheel bearing surface of the block and are stopped at the thick rear part, the block is pressed against the floor by the car's own weight, making the connection with the floor even stronger. . Therefore, there is no fear that the block will be displaced due to contact with the wheels of the vehicle. Furthermore, since the top surface of the car stopper block of this invention has a concave arc shape, the contact surface between the wheels and the tires is widened, so that even when the car is parked for a long period of time, it does not adversely affect the tires.

Claims (1)

[Scope of utility model registration request] The wheel bearing surface is formed in a cross section in the front-rear direction so that the front part is low and gradually becomes higher towards the rear, forming a concave arc shape, and the cross section in the left-right direction is horizontal.
By making the front part thinner and the rear part thicker, the height difference between the front and rear parts is much lower than the radius of the wheel. A concrete car stop block designed to prevent backing up, with the front and rear sides having slopes with recessed tops.
