FR2762026A1 - Precast concrete or rubble block assembled using sprayed mortar - Google Patents

Abstract

The blocks are 20 cm x 20 cm x 50 cm or 20 cm x 25 cm x 50 cm or can be made in other sizes. The blocks have openings which allow the mortar to penetrate. The blocks are assembled dry, four or fives rows at a time, and mortar is sprayed into the openings. The lower surface of the block has bevelled edges 2 cm wide forming a groove which enables mortar to be injected forming a horizontal joint. The vertical face has grooves which allow the blocks to be aligned and the grooves leave a vertical space into which mortar can be inserted forming a vertical joint.

Description

 The present invention relates to the new form of a rubble or concrete block and the new way of laying it.

 The rubble has a different shape from existing rubble. The way of laying it changes completely.

 We put it down and then fill the joints by mechanical projection. What allows to have a yield four times higher.

 So an incomparable speed of installation.

 This invention relates to the installation of all the rubble which can be manufactured in 20 CM X 20 CM X 50 CM, in 20 CM X 25 CM X 50 CM or another dimension.

 The rubble stones are laid by horizontal casing then by lining the joints by mechanical projection and possibly at the same time we can roughen the walls.

 The composition of the materials making up the concrete block or rubble can be the same as that of existing rubble.

 The filling can be done even from the top of the rubble with a more liquid mortar but always with a machine projection. At that time we will fill one row at a time. This pouring will be done through the holes which are used to lay the rubble stones.

 The rubble or concrete blocks are laid dry. We put five or six rows in a row.

 Then we spray the mortar on the rubble joints with the spraying machine. Since it sends the mortar with pressure, the mortar will penetrate the rubble and we can leave two or three centimeters inside the rubble. This operation will be done with a slightly liquid mortar so that the mortar distributes well level.

Claims (1)

CLAIM  10) Method of laying construction elements of the rubble or concrete block type (overall dimension 50X20X25 or 50X20X20) characterized by the following steps - use of elements provided with orifices (1, 3 or 4)  mortar tration - dry assembly by interlocking of the elements - placement of the laying mortar by the orifices by projecting  mechanical tion  2 ") Building element intended to be used in the method according to claim 1, characterized by a lower face releasing by bevelled parts of 2 CM a lumen (3) allowing the injection of the mortar; this achieving the horizontal connection.  3) Building element intended to be used in the method according to claim 1 or building element according to claim 2, characterized by a vertical face with stable interlocking (2), allowing the alignment of the block and providing a vertical space facilitating the placement of mortar; this constituting the vertical connection.
