Abstract

PURPOSE:To improve workability and strength by installing a trapezoid block, on which a vertical through-hole is formed, on a road surface, inserting a reinforcement into a road surface bored section formed at the position of the through-hole, injecting mortar and fixing the reinforcement. CONSTITUTION:A block body 1, which has an approximately trapezoid cross section, at corners of which R is formed and the inside of which is hollowed as required, is mounted. Vertically penetrated cylindrical cement holes 2 are formed near both ends of the main body 1 while cut sections 3 for holding are formed at both ends of an underside. The main body 1 is installed on a road surface, the central sections of the holes 2 of the road surface are bored by a drill, reinforcements are inserted into the holes, and cement mortar is injected and the reinforcements are fixed. Accordingly, the block body 1 is easily handled because of light weight, the cost of construction and the term of work can be reduced, no angular section is shaped and safety can be improved, and mounting strength can be increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is a lightweight, easy-to-handle car stop block to be installed in a parking lot that is currently growing on a nationwide scale with the increasing demand for automobiles. In addition, the present invention relates to a new car stop block that can be shortened in construction period and its installation method.

[0002]

2. Description of the Related Art Conventionally, a concrete block for a car stop is generally in the shape of a bar having ridges at all corners and is unsafe. A heavy block of about 20 to 50 kg is used for transportation. It was difficult. In addition, most of the installation methods required cutting the pavement surface, embedding blocks, and then performing back-paving, and the finished aesthetics were also inconvenient and inconvenient. There is also a method of attaching a small block to the pavement surface with a bonding agent, but this is low in strength and the car stop block will immediately fall due to the impact of the car,
Construction is easy but not much done.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention is a novel car stop block installed in a parking lot, which is safe, lightweight and easy to handle, and the installation and construction thereof is safe, reliable, inexpensive and has a short construction period. The purpose is to provide a car stop block and its installation method.

[0004]

In order to achieve the above object, first of all, a bollard block according to the present invention has a substantially trapezoidal cross section of which length, width and height are appropriately dimensioned, and an appropriate length in which R is provided at an upper ridge. The block main body is provided, and the cement holes penetrating from the upper surface to the lower surface are drilled left and right near the inside from both the left and right ends of this block, and the appropriate width at the lower parts of the left and right ends,
It is a car stop block that is formed by forming side surface cutting parts for cues that penetrate the front and rear surfaces at a height. Next, as the installation method, first install the car stop block at a predetermined position, drill holes at the left and right cement hole positions in the asphalt and the ground with a depth of about 35 cm, and insert reinforcing bars of the same length into this. Then, cement mortar is injected from the cement hole into the hole around the reinforcing bar to fix the car stop block and the reinforcing bar, and the upper part of the cement hole and the peripheral part and the lower part of the block are pressed with a trowel for finishing.

[0005]

The car stop block of the present invention constructed as described above can be lightened by hollowing out the inside of the central portion if necessary, so that it is light at about 15 kg as a whole and formed at the lower ends of both ends. Both hands can be placed on the cue cutting part for easy transportation and installation. In addition, the ridgeline on the top surface is rounded, so it is highly safe.

Also, in the installation method, centering is easier than the conventional method because of post-paving construction, and the blocks are light as described above, so transportation and installation work is easy, and the construction period is usually one day. The process is short and the construction cost is 7 compared to the conventional one.
It is relatively inexpensive with 0 to 80%, has high strength, and its workability is almost unaffected by the weather, and all-weather construction is possible. Moreover, it has a high record of safety.

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, a block main body 1 having a substantially trapezoidal cross section and measuring lengths on the upper ridge and corners and having an appropriate length is provided. 2 is penetrated to the left and right respectively, and at the lower parts of the left and right ends, a cue cutting portion 3 for penetrating the front and rear surfaces is formed at an appropriate width and height, and if necessary, the inside of the central portion is cut off to form a hollow portion 4 It is a car stop block formed by forming.

Next, an embodiment of the installation method will be explained.
Is a block cross-sectional view in the center of the cement hole 2 of the car stop block body 1. After drilling the center of the cement hole 2 of the block 1 installed on the asphalt pavement surface A with a drill, insert the reinforcing bar 5 in the center. Then, the cement mortar 6 is injected around it and the car stop block is fixed and installed. Normally, the depth of the hole from the asphalt pavement surface is about 350 mm, and the length of the reinforcing bar is about 400 mm.

[0009]

Since the present invention is constructed as described above, it has the following effects. In consideration of safety, the car stop block of the present invention is rounded in all corners in terms of shape, and in consideration of workability, claw cutting parts are formed at the lower ends of both ends, and a hollow part is further provided. It is a new car stop block that is lighter and can be installed with a reflector etc. by using cement holes. And as this installation method, after drilling at the position of the cement hole on the asphalt pavement surface with a drill, after inserting mortar cement, inserting a reinforcing bar, installing a car stop block into this and filling the cement hole with mortar, finishing with a trowel It is an invention that can be expected to make an epoch-making contribution to the maintenance of parking lots by using the earth pin construction method of fixing by fixing it at a low cost, with a fast construction period and high strength.
