Method for constructing a building using bricks connected using dry joints

Abstract

The invention relates to a brick ( 1 ) made from a material comprising vegetable fibres agglomerated using a binder (such as hemp concrete), said brick being provided with a groove ( 9, 11 ) and a tongue ( 5, 7 ) allowing the dry-joint connection of bricks. The invention also relates to a method for constructing a building using such bricks.

1 . A method for constructing a building using prefabricated bricks made from a material comprising plant fibers agglomerated using a binder, provided with grooves and tongues allowing them to be fitted together, wherein the bricks are conned through dry-joint connection. 
     
     
         2 . The method according to  claim 1 , further comprising the combined placement of solid base bricks, provided with a groove and a tongue wherein that can be joined together, and honeycomb stiffening bricks, provided with a groove wherein and a tongue, that can be joined together as well as a cell with the passage of a reinforcing post. 
     
     
         3 . The method according to  claim 2 , further comprising:
 producing a mortar base;   placing a series of posts wherein in the base;   placing stiffening bricks at the posts wherein, with insertions of said posts into the cells of the stiffening bricks; and   placing base bricks between the stiffening bricks.   
     
     
         4 . The method according to  claim 3 , wherein each post comprises a metal framework embedded in concrete. 
     
     
         5 . The method according to  claim 3 , comprising an operation for placing, at a post and above a stiffening brick, a half-stiffening brick, provided with a tongue to allow it to be joint-connected on the stiffening brick and a cell for the passage of the post, and having a length equal to half the length of the stiffening brick. 
     
     
         6 . The method according to  claim 3 , further comprising:
 placing linking bricks comprising a tongue allowing them to be joint-connected in the grooves of other bricks, and a central cavity delimiting two side walls and a bottom;   placing a metal framework in the cavity;   filling in the cavity using concrete.   
     
     
         7 . The method according to  claim 3 , further comprising:
 placing linking bricks comprising a tongue allowing them to be joint-connected in the grooves of other bricks, and a central cavity delimiting two side walls and a bottom;   cutting out side walls;   placing a slab resting directly on the bottom of the linking bricks.   
     
     
         8 . A brick made from a material comprising plant fibers agglomerated using a binder to implement the method according to  claim 1 , provided with a tongue designed to be joint-connected in a groove, wherein the tab has a height whereof the ratio to an effective height or an effective width of the brick is comprised between 1/10 and 1/4. 
     
     
         9 . The brick according to  claim 8 , wherein the ratio between the height of the tongue and the effective height or the effective width of the brick is approximately 1/6. 
     
     
         10 . The brick according to  claim 8 , wherein the material is hemp concrete.
