Abstract

PROBLEM TO BE SOLVED: To provide a block pavement reinforcing plate for forming a barrier- free pavement which has sufficient water permeability and hard-to-foul characteristics even in using immaculate blocks by achieving smooth permeation of rain water through joints and which has no water gradient on the surface by providing sufficiently storable water reservoirs on the lower part of the surface layer of the pavement, thus giving a barrier-free pavement, preventing the flooding of a river in a city and giving less shock to heels during walking. SOLUTION: The block pavement reinforcing plate comprises a base plate to be located on the bottom surfaces of angular portions of the blocks placed back and forth, and right and left, a cross joint plate formed on the upper face of the base plate for forming a water permeable joint portion between the blocks placed in the backward and forward and lateral directions, and a plurality of supporting members formed on the upper face of the base plate for forming the water reservoir on the bottom surfaces of the blocks in contact with the bottom surfaces of the blocks placed in the backward and forward and lateral directions.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block pavement reinforcing plate that can be laid while forming water-permeable joints between laid blocks.

[0002]

2. Description of the Related Art Conventional permeable block pavement uses a method in which rainwater is guided to a roadbed by making the entire block porous, or a method in which the surface is dense and the base layer is porous and penetrates from joints filled with joint sand. Has been done. Further, as the elastic block pavement, blocks made of a soft material such as rubber or wood chips are mainly used.

[0003]

However, in the conventional method of making the entire block of a water-permeable pavement block porous to allow rainwater to permeate therethrough or to allow rainwater to permeate through joints, the block surface and joints are clogged with mud and the water permeability decreases. In addition to the disadvantage that the porous block cannot withstand the freeze-thaw action in cold regions. Also, both methods require a gradient for surface drainage,
Not suitable for wheelchair users. Moreover, when using solid blocks such as natural stone, an appropriate water-permeable pavement could not be obtained. The conventional elastic block pavement using rubber or wood chips has a problem in durability of the pavement surface.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
By allowing rainwater to penetrate smoothly from the joints, sufficient water permeability can be obtained even when using solid blocks, and clogging is difficult.Also, a sufficient water storage tank is provided below the surface of the pavement to create a pavement surface. It is an object of the present invention to provide a block pavement strengthening plate that eliminates the water gradient in the road and creates pavement that is barrier-free, prevents flooding of city rivers, and reduces shocks on the heel during walking.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are only for explanation and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above object, the present invention has a base plate which can be positioned on the bottom surface of a corner portion of a block which is laid in the front, rear, left and right directions, and is formed on the upper surface of the base plate. A cross-shaped joint plate that forms a water-permeable joint between blocks that are laid in the front, rear, left, and right, and a bottom surface of the block that is laid in the front, rear, left, and right formed on the upper surface of the base plate and is in contact with the bottom surface of the block. A reinforcing plate for block paving is configured with a plurality of support pieces forming a water tank.
Further, the present invention provides a base plate that can be positioned on the bottom surface of a corner portion of a block that is laid in front and rear or left and right, and a block that is laid in front and rear or left and right formed on an upper surface including one side surface of the base plate. A plurality of T-shaped joint plates forming a water-permeable joint between them, and a plurality of water tanks formed on the bottom surfaces of the blocks by contacting the bottom surfaces of the blocks formed on the upper surface of the base plate in the front-rear or left-right directions. Reinforcement plate for block paving is composed of individual support pieces.
