FR2778934A1 - Insulating and draining construction block - Google Patents

Abstract

The construction block utilizes draining cells (1,2,3) on the external face. Rainwater is captured through holes (14) and evacuated by the cavities (15). Some cells (4,5,6,7,8) are filled with clay to reinforce the insulation.

Description

  [, a present invention relates to a building block and its new structure. Existing blocks are often cement blocks used for raising walls or more sophisticated blocks incorporating into their structure

  insulating, thermal or phonic parts, see both.

  They sometimes combine a facing material which gives them a

decorative function.

  This innovation adds a draining function to the construction and avoids the juxtaposition of products of different structures, thus canceling out the

  difficulties of use and the fragility that may result.

  This invention is carried out using a specific material of low density (1 kg / dm3), thermal insulator (0.25W / mk) and resistant to

compression (150 kg / cm2).

  The qualities of this component can be increased by adding

  of water repellent making it waterproof against any external infiltration.

  A fungicide treatment makes the block more stable over time, especially

  in decorative use without plasters.

  Different colors can then be associated with the material in order to

  conform to those used in each region or even country.

  2 sizes: 60/30/2 () and 50/25/20 2 draining versions and reservation 2 options normal insulation and reinforced insulation All these sizes, versions and options are found in the block

common or decoration block.

  The major consequence of this invention is the disappearance of certain interventions, in particular in the case of a decoration block in the reservation version (no exterior or interior coatings, no double partition, protected and concealed networks). Thus, the cost of construction is reduced. The draining version also allows to avoid complex interventions. During the construction of a traditional basement, it is necessary to create a gutter on the plan of the foundations, to set up a catchment drain, to coat and to undergo an asphalt treatment on the whole surface

  buried. It is also necessary to constitute a drain over the entire height of the

ground.

  In the case of a drain made of gravel, this must be protected before backfilling with a decontaminating felt to avoid

  the pollution of these draining materials by the earth which surrounds them.

  - 2 - With the use of the block, only this last operation remains essential to prevent sludge or fine particles from entering

  draining cells of the block (1,2,3) at the risk of blocking it.

  The felt will therefore be placed in front of the water collection holes (14) over the entire buried surface, and will be maintained by a simple and punctual gluing. The two options (normal insulation and reinforced insulation) make it possible to adapt to climatic constraints whatever the geographical situation. Reinforced insulation is created by filling certain cells (4,5,6,7,8) with a material such as expanded clay which is of density

  low and which ensures a good insulation coefficient.

  The mass of a block will not be a handicap during its installation because that of a block of 60/30/20 in option reinforced insulation remains clearly lower than that of a traditional block of 50/27/20 while being neighbor of

that of a simple 50/20/20 block.

  All the qualities of the block will be maintained at all stages

  of construction through the use of suitable elements.

THE INSULATING AND DRAINING BLOCK

  Allows: - traditional masonry, - the making of a drain by using the draining cell on the external face of the construction (1,2,3). Water is captured by

  holes (14) and evacuated by the reservations (15).

  -the creation of the space necessary for the passage of the electrical, telephone and even water networks when the draining cell is placed on the internal face and this without risking destructuring the construction by recessed grooves. In this case, the water supply is in the frost-free position. (1,2,3,15) In addition: - the fungicidal treatment avoids the degradation and premature aging of the material, - its water-repellent nature dispenses with the use of exterior plasters, - the insulation it provides allows '' avoid the double interior partition

  with or without interior plasters (plaster or others).

  - the possibility of placing blocks!

  interior or exterior decorative use of the material.

  (A brushed finish can be considered to improve the decorative character of the material.) - the weight of the blocks, identical to that of a traditional cement block, does not make the installation of the elements more difficult and offers a clear reduction in the number of operations. Tcmpà of work and cost of

construction are therefore reduced.

  - the adapted elements ensure a perfect seal of

  all while removing thermal bridges.

  - the insulating binder also removes thermal bridges and its water-repellent quality completes the sealing of the whole. This binder will

used with water-repellent adjuvant.

  -the strilles located on the vertical joints (16) make it conform

  earthquake-resistant assembly standards for such materials.

  the holes (14) in the face of the block will only be made for

draining use.

  -the compartment (17) allows the casting of corner posts or

  masonry reinforcements in case of support.

Claims (5)
