Abstract

The draining concrete block (1) has the same dimensions as a standard 20x20x50cm B40 concrete block. The 2 holes intended to carry the concrete block are modified into a 10mmx30mm slot (6) for example so as to be able to insert a tool and thus facilitate handling .The upper surface of the concrete block has small holes (2) to allow the passage of water into the cells (4)(5) (one hole per cell). The diameter of the holes is between 5mm and 10mm in order to to prevent them from getting clogged and not to cause problems with the objects that will be placed on the terrace. The holes are located on the edge of the cells (2)(4) and not in the middle of the cells for better resistance . All water that falls on the terrace or sidewalk is drained immediately where the water fell, even in the event of heavy rain, no puddles form. The draining concrete block has a capacity of 20cm of water, which is considerable. Figures for the abstract: [Fig. 1]

Description

Draining concrete block

The present invention relates to the field of construction of terraces (10) and sidewalks (11) around homes (7) and swimming pools with the aim of effectively draining rainwater, splashing water around swimming pools, cleaning by watering.

This type of terrace makes it possible to put the level of the terrace at the same level as the floor of the home without creating infiltration at the level of the slab.

This type of terrace does not require a slope and this is the desired goal from an aesthetic point of view and becomes essential for example for a U-shaped home. (7)

Inside the U all the bay windows (12) are at the same height, a slope would be difficult to manage.

• Un coût élevé des dalles d’une épaisseur de 2cm
• Un coût élevé des plots
• Une grande quantité de plots
• Quand il a plu, les dalles restent mouillées et il est nécessaire de passer une raclette

The design of a terrace or sidewalk using draining concrete blocks is an excellent alternative to laying 60x60 slabs on pedestals, which has some disadvantages:

• A high cost of slabs with a thickness of 2cm
• High cost of plots
• A large quantity of studs
• When it rains, the tiles remain wet and it is necessary to use a squeegee

• La structure des plots retient l’eau et favorise la prolifération des moustiques.

or wait for the water to evaporate.

• The structure of the blocks retains water and encourages the proliferation of mosquitoes.

The draining terrace (10) or sidewalk (11) is made up of draining concrete blocks (1) aligned and placed on a draining soil made up of a geotextile and 15 to 20 cm of 10/20 limestone, the limestone is compacted, tamped and upgraded.

A first row of draining concrete blocks is placed all around the part of the house where the terrace (8), the sidewalk or around the swimming pool is to be built, and in the direction of the length of the concrete block. The width of the concrete block will have a very slight slope, 1% over 20cm that is 1 or 2 millimeters, the slope is continuous with that of the bay window thresholds (12) for example.

All other draining concrete blocks are installed in a line and without slope. (9)

The underside of each concrete block is manually tamped to obtain the correct position of the concrete block, a perfect level in the direction of width, length and height using a laser.

All the draining concrete blocks (1) are laid in lines directly on the limestone and only glued together with mortar on the part provided for this purpose (14). The lines of draining concrete blocks are just placed next to each other and offset by ½ concrete block (13), this makes it easier to adjust the position of the concrete blocks.

The juxtaposition of the lines of draining concrete blocks already offers the possibility of evacuating water.

A terrace was made with normal concrete blocks, but this took time and a lot of mortar consumption.

In fact, you have to fill the 2 holes with mortar and drill holes above each of the cells.

If you use corner concrete blocks, you have to fill the huge hole with mortar.

The present invention specifically concerns the structure of the draining concrete block in order to reduce the installation time and the volume of mortar to be installed, which amounts to reducing the construction cost, while improving performance.

• Le parpaing drainant (1) a les mêmes dimensions qu’un parpaing standard 20x20x50cm B40.
• Les 2 trous prévus pour porter le parpaing sont modifiés en une fente de 10mmx30mm (6) par exemple de manière à pouvoir incérer un outil et ainsi faciliter la manutention.
• La surface supérieure du parpaing est dotée de petits trous (2) pour permettre le passage de l’eau dans les alvéoles (4)(5) (un trou par alvéole).
• Le diamètre des trous est compris entre 5mm et 10mm afin d’éviter qu’ils se bouchent et pour ne pas provoquer de problèmes avec les objets qui seront posés sur la terrasse.
• Les trous sont situés sur le bord des alvéoles (2)(4) et non pas au milieu des alvéoles pour une meilleure résistance.
• Le parpaing drainant doit être suffisamment résistant pour supporter par exemple une personne forte assise sur une chaise dont le piètement est en tube de 15mm de diamètre
• Le parpaing drainant peut être facilement coupé en son milieu au niveau de l’alvéole (5).

Description of the draining concrete block:

• The draining concrete block (1) has the same dimensions as a standard 20x20x50cm B40 concrete block.
• The 2 holes intended to carry the concrete block are modified into a slot of 10mmx30mm (6) for example so as to be able to insert a tool and thus facilitate handling.
• The upper surface of the concrete block has small holes (2) to allow the passage of water into the cells (4)(5) (one hole per cell).
• The diameter of the holes is between 5mm and 10mm in order to prevent them from getting clogged and not to cause problems with the objects that will be placed on the terrace.
• The holes are located on the edge of the cells (2)(4) and not in the middle of the cells for better resistance.
• The draining concrete block must be strong enough to support, for example, a strong person sitting on a chair with a 15mm diameter tube base.
• The draining concrete block can be easily cut in the middle at the level of the cell (5).

• Le parpaing drainant a une capacité de 20cm d’eau, ce qui est considérable.
• La terrasse drainante peut-être recouverte d’un gazon synthétique qui est lui aussi est drainant ou tout autre revêtement drainant.

All water that falls on the terrace or sidewalk is drained immediately where the water fell, even in heavy rain, no puddles form.

• The draining concrete block has a capacity of 20cm of water, which is considerable.
• The draining terrace can be covered with synthetic turf which is also draining or any other draining covering.
