Definitions
- the invention falls within the field of building and construction.
- the object of the present invention is to provide improvements in the construction of building walls by means of insulating shuttering blocks of parallelepiped shape and extending along a longitudinal axis. These insulating shuttering blocks allow easy installation and time-saving reinforcement installation, savings in concrete, while facilitating the passage of electrical ducts and / or water supply networks embedded through orifices provided for this effect during manufacture.
- These blocks mostly polystyrene, which are molded either in one piece with their spacers integrated into the molding, whether they are themselves in the same material as the walls of the block or in another material, metallic for example, either molded in 2 face pieces (facing walls) which will then be joined by a spacer, in material of plastic type in general, to form the shuttering block, often making installation difficult and difficult rebars and rebars pre-assembled in these blocks.
- the block is manufactured and constituted by two facing walls that must be assembled by a spacer
- the implementation of the reinforcing bars, especially horizontal (that is, say parallel to the longitudinal axis of the blocks) is greatly facilitated provided that the spacers are only through and are not closed "frames".
- the result of this design is a loss of time due to the assembly of the blocks, often obscured by sales agents, which negates the time saved on the installation of the blocks themselves, which are light and often larger unit dimensions, on the wall surface, than the traditional concrete block with mineral aggregate.
- the existing shuttering blocks are generally available in a wide choice of manufacturing widths which varies essentially by the thickness of one or both walls of the block.
- the internal dimension available for pouring concrete is imposed and the quantity of concrete to be used is large and often overabundant in relation to the structural needs of the building to be produced.
- the internal fixed widths mainly vary between 14 and 21 cm.
- the wall made before the concrete is poured is not very rigid and capable of moving on a simple pressure of the wind and, then when the concrete is poured, shoring brackets, of storey height, are generally used.
- the concrete placement instructions vary according to the products and manufacturers, ranging from: the entire height of the wall in a single step, to several stages of pouring at different successive heights.
- the object of the invention is to provide a molded block whose characteristics provide both great simplicity in its manufacture, in its implementation, in an easy installation of the reinforcing bars and pre-assembled reinforcements, a significant saving on the quantities of concrete to be used, while optimizing the average thermal resistance of the wall and facilitating the passage of electrical ducts and / or embedded water supply networks .

- Block 1 according to the invention is an improvement which allows simplified implementation and offers improved thermal insulation performance.
- the block 1 is of general parallelepipedal shape, more precisely in the form of a block with rectangular section, and extends along a longitudinal axis X.
- the block 1 comprises four side walls 5, 20, 21, respectively two transverse side walls 20, 21 and two longitudinal side walls 5.

- the block 1 comprises a plurality of wide grooves 2, 3, 4 formed in its two transverse walls 20, 21 and in its upper and lower walls 25, 26. These wide grooves 2, 3, 4 will be described in detail later in the description.
- the block 1 also has holes passing through 6 said vertical through holes 6, formed in the longitudinal side walls 5 and which extend perpendicularly to the upper 25 and lower 26 walls.
- These vertical through holes 6 provide a passage for the ducts electrical in particular, without the need to subsequently groove the wall formed of such blocks 1 on the site.
- these passages formed by the through orifices 6 are marked on the faces 7 of the longitudinal side walls 5 by at least one mark 16 to facilitate the positioning during drilling, on site, of the reservation of the electrical boxes and / or of the outlets. water supply networks.
- this block 1 does not require any spacer and is easily cut to form in length or in height, the block portions necessary for the realization of a wall table or of a lintel, for example.
- the term “height” will be assimilated to any dimension in a direction perpendicular to the upper and lower walls of the block.
- the term “length” will be assimilated to any dimension in a direction parallel to the longitudinal axis of block 1, and the term “width” will be assimilated to any dimension in a direction parallel to a transverse axis of said block 1.
- the wide grooves 2, 3, 4 formed in the walls 5, 20, 21 of the block 1 can easily receive a pre-assembled reinforcement, both vertically and horizontally, over standard lengths several meters, before the adjacent block comes to close the cavity.
- the term “vertical” will be assimilated to any direction perpendicular to the upper and lower walls 25, 26 of the considered block 1, while the term “horizontal” will be assimilated to any direction parallel to said upper and lower walls 25. , 26.
- the block 1 which is in the form of a straight block of length L1 and width L2 and which is in one piece, comprises four longitudinal grooves 2 with a quadrilateral section, which longitudinal grooves 2 are formed in pairs in the respectively upper 25 and lower 26 walls of block 1.
- the two longitudinal grooves 2 of the same pair are parallel to each other and extend over the entire length L1 of block 1.
- the two grooves 2 of the same pair are separated by a central longitudinal dividing wall 9.
- the block 1 comprises two opposing central longitudinal dividing walls 9 of the same width, respectively called the upper central wall and low central wall.
- H2 the height separating the bottom of the top groove 2 from the bottom of the opposite bottom groove 2 of the block 1 is denoted H2.
- the longitudinal side walls 5 are of equal thickness Ep.
- all the longitudinal grooves 2 have identical sections and are therefore of the same width L6.
- the longitudinal grooves 2 formed in the upper wall 25 will be referred to as the upper horizontal grooves, while the longitudinal grooves 2 formed in the lower wall 26 will be called the lower horizontal grooves.
- These top and bottom horizontal grooves 2 placed symmetrically make it possible, whatever the chosen arrangement of the block 1, to place in continuity the reinforcements of longitudinal stiffeners 14 called horizontal stiffeners 14 (see in particular Figures 8 to 10), as will be specified. in more detail in the remainder of the description.
- the block 1 also comprises first and second vertical grooves 3, 4 with a quadrilateral section, respectively provided in one of the transverse side walls 20 and in the opposite transverse side wall 21. These vertical grooves 3, 4 extend perpendicularly to the upper and lower walls 25, 26 of block 1 over the entire height H1 of said block 1.
- the first vertical groove 3 is centered in the considered transverse side wall 20, and has a width L5 equal to the cumulative width of the two longitudinal grooves 2 of the same pair and the central wall 9 separating these two longitudinal grooves 2.
- the second vertical groove 4 is arranged in alignment with two opposed longitudinal grooves 2 respectively provided in the upper and lower walls 25, 26.
- the width L6 of the second groove vertical 4 is equal to the width L6 of the longitudinal grooves 2.
- the first and second vertical grooves 3, 4 therefore have different widths.
- the two central partition walls 9 of the block 1 each have a longitudinal recess 10 formed at the level of the central wall in question 9 near the second vertical groove 4.
- These two recesses 10 thus form two spaces with a rectangular section which s 'extend perpendicularly to the two upper and lower walls 25, 26, each over a height equal to the height of the longitudinal grooves 2, and over a width equal to the cumulative width of one of the longitudinal grooves 2 and of the central partition wall considered 9.
- An advantage conferred by the design of the block 1 is its reversibility. This makes it possible to manufacture only one model of block 1 per wall thickness to be produced, or per desired thermal performance.
- the block 1 comprises projecting devices 8 in the form of a dovetail formed on a face 7 of at least one of the longitudinal side walls 5, as shown in FIG. 6.
- These faces 7 presenting the projecting devices 8 are designed to receive a finishing complex of the type coated with cement or other binder, plaster or plaster panels, and said projecting devices 8 facilitate the attachment of the finishing complex to the faces 7 of the block 1.
- two adjacent blocks 1 are butted so that their first 3 or second 4 vertical grooves are opposite.
- it is defined between two adjacent blocks of the assembly either a vertical quadrilateral space 23 formed by the two first grooves 3 facing the two adjacent blocks 1, or a vertical quadrilateral space 24 formed by the two second grooves 4 facing said adjacent blocks 1.
- block 1 The dimensional characteristics of block 1, and in particular the arrangement of its longitudinal 2 and vertical grooves 3, 4, allow the reversibility of block 1 so that the latter is always positionable with its grooves 2, 3, 4 in symmetry of those of blocks 1 which adjoin it.
- the tongues 11, 12, if they are produced by the manufacturer of the blocks 1, can optionally be placed in the grooves 2, which significantly reduces the transport volume.
- the cuts on site are easily achievable with manual or portable power tools.
- the cuttings are easily reusable and the losses are very limited.
- the smallest block widths 1 will greatly exceed the minimum thermal resistance required by the regulations in force, including with the least efficient materials in terms of thermal conductivity, and slightly greater thicknesses will very easily exceed the criteria required for passive constructions.
- the block assembly 22 and / or the wall formed of several sets of blocks 22 include a plurality of tabs 11, 12 of the same material as the block 1 and in the form of a straight block, designed to be inserted into the longitudinal grooves 2 of the blocks 1.
- These tongues 11, 12 have the advantage of optimizing the thermal resistance of the longitudinal transverse walls 5 without reducing its mechanical strength.
- the height of these tongues 12 may be equal to the height of the longitudinal grooves 2, in particular when such a tongue 12 is inserted in a block 1 disposed either at the foot or at the top of the wall.
- the height of these tongues 11 can be equal to twice the height of the longitudinal grooves 2, in particular when such a tongue 11 is inserted into the space formed by two longitudinal grooves 2 facing two superposed blocks. 1.
- Each tongue 11, 12 also has a width L6 substantially equal to the width L6 of the longitudinal grooves 2.
- tongues 11, 12 also make it possible to facilitate the assembly of the blocks of the same set, by being inserted into two longitudinal grooves 2 opposite two abutting blocks 1 (see in particular Figure 9).
- Shims or complementary small pieces of different dimensions can easily be cut from these plates, or from cuttings from corner blocks, for example, with manual or power tools.
- Nails suitable for maintaining pieces of foam can also be used to complete the good maintenance of various parts thus added, and in particular the maintenance of the tongues 11, 12 in the longitudinal grooves 2.
- the block assembly 22 and / or the wall can be reinforced by longitudinal stiffeners called horizontal stiffeners 14, and so-called stiffeners verticals 13 extending perpendicularly to the upper and lower walls 25, 26 of the blocks 1 making up the assembly 22 and / or the wall.
- stiffeners 13, 14 include linear reinforcements that can measure several meters in length in order to reinforce the blocks 1 of the same set 22 and / or the same wall.
- block 1 makes it possible to constitute a mesh of vertical 13 and horizontal 14 stiffeners which partly reconstruct the mechanical strength characteristics of a poured concrete wall without, however, using as much concrete.
- the thermal resistance must be preserved by avoiding affecting it by large concrete sections near the faces 7 of the longitudinal transverse walls 5.
- the arrangement of the vertical grooves 3, 4, which make up half of a cavity or vertical space 23, 24 to receive a concrete reinforcement must be alternated with a vertical stiffener 13 which will be arranged parallel to the two longitudinal transverse walls 5 of the block 1 and with another vertical stiffener 13 which will be arranged there perpendicular to the two longitudinal side walls 5.
- the set of blocks 22 comprises a plurality of vertical stiffeners 13 inserted into the vertical spaces 23, 24 formed by the first and second vertical grooves 3, 4 facing each other.
- a longitudinal stiffener 14 is inserted into the longitudinal grooves 2 facing and aligned blocks 1 forming the assembly 22.
- each block 1 of the assembly comprises, in its longitudinal groove 2 aligned with the second vertical groove 4 and which does not include the longitudinal stiffener 14, a tongue 1 1, 12 whose length L3 is equal to the distance separating two consecutive vertical stiffeners 13.
- Figures 13 and 16 illustrate examples arrangements of such vertical stiffeners 13.
- the longitudinal stiffener 14 is inserted into the longitudinal grooves 2 facing the blocks 1 forming the assembly 22, each longitudinal groove 2 of the considered block 1 being aligned with the second vertical groove considered 4.
- the two butted central blocks 1 are assembled by a single tongue 11, the length L4 of which is equal to the length separating two consecutive vertical stiffeners 13 inserted in spaces 23 formed by the first vertical grooves 3 facing each other. This length L4 is twice the length L3.
- the assembly and the maintenance between them of the blocks 1 can therefore be provided by a tongue 11 or 12, of parallelepiped shape and of length L3, L4 equal to the distance between two vertical stiffeners 13, to be inserted into the grooves horizontal 2 must not receive horizontal stiffeners 14.
- the set of blocks 22 does not include tongues 1 1, 12, but two longitudinal stiffeners 14 arranged in the longitudinal grooves 2 of the blocks 1.
- the set 22 also comprises vertical stiffeners 13 arranged in the same way. as for the whole 22 of the first configuration.
- the arrangement of the horizontal grooves 2 of the block 1 offers the possibility of choosing the position of the horizontal stiffener 14, on the inside or outside of the wall, or even use both.
- the position of the horizontal stiffener 14 as shown in Figures 12, 13, 15, 16, these tabs 1 1, 12 ensure the maintenance of two blocks 1 in horizontal continuity and vertical continuity while making thermal losses almost zero.
- the blocks of the upper assembly 22 each comprise in one of the upper grooves 2 a horizontal stiffener 14 and in the other upper groove 2 a tongue 1 1, and two tongues 1 1, 12 in the respective lower grooves 2;
- the blocks of the central assembly 22 each comprise in one of the upper grooves 2 a horizontal stiffener 14 and in the other upper groove the tongue 1 1 arranged in the lower groove considered 2 of the upper block considered, and two tongues 12 in the respective lower grooves 2. This configuration is also applied to sets of blocks 22 liable to be subjected to current shocks which could have an impact on the strength of the wall;
- the blocks of the lower assembly 22 each include in the upper grooves 2 two horizontal stiffeners 14 and in the lower grooves 2, respectively a horizontal stiffener 14 and a tongue 12.
- connection of the vertical stiffeners 13 with the horizontal stiffeners 14 must be ensured at each row even when a horizontal stiffener 14 is not placed in the longitudinal groove where there is a vertical stiffener 13 isolated at this row.
- openings between the horizontal grooves 2 must allow the establishment of reinforcing bars 15 connecting an isolated vertical stiffener 13 with the horizontal stiffener 14 passing through the opposite groove 2, such that illustrated in Figures 8, 10 and 16. These openings are the spaces formed by the longitudinal recesses 10 formed at the ends of the central walls considered 9 and described above.
- the general embodiment of the walls is similar to the majority of other systems by juxtaposition and superposition of the shuttering blocks or of the shuttering blocks, without it being useful to describe the various operations of realization of the structural parts in reinforced concrete which come under their DTU.
- the blocks 1 can be assembled by simple juxtaposition to form crosses as shown in Figures 17 to 21, or possibly be cut to form an angle as shown in Figure 22.
- the material constituting the blocks can be, without limitation, an expanded polystyrene, an extruded polystyrene, a graphitized polystyrene, a polyurethane foam or a cellular concrete or a very light concrete and, optionally, terracotta to form a honeycomb block 1.
- the spacing between the reinforced concrete stiffeners should make it possible to avoid the risks of intrusion by perforation of these spaces located between the vertical 13 and horizontal 14 stiffeners.
- the block 1, in particular illustrated by Figures 1 to 3, consists of:
- a central dividing wall 9 disposed between the longitudinal grooves 2 of the same pair and of the same height as these, which central wall 9 has, on its end near the vertical groove 4, a recess 10 in length;
- the distance L3, separating the transverse walls 20, 21 at the level of the first and second vertical grooves 3, 4, should not exceed a dimension allowing an intrusive passage.
- the height H2 separating the bottom of the top groove 2 from the bottom of the opposite bottom groove 2 of the block 1, should not exceed a dimension allowing intrusive passage.
- this dimensional arrangement makes it possible to reinforce the mesh formed by the vertical 13 and horizontal 14 stiffeners and to limit damage due to violent accidental impacts.
- the thickness Ep of the longitudinal side walls 5 of block 1 may be variable, but will always be identical on both sides of the same block 1.
- the vertical through holes 6 can be included in a diameter of 16 to 30 millimeters.
- the vertical marks 16 indicating the location of the vertical through holes 6 are materialized by a marking or by an indentation of between 1 and 3 millimeters.
- the tabs 11 and 12 illustrated in Figure 4 include:
- the tongues will be of the same width as that of the longitudinal grooves 2.
- a tongue 11 will be of a height equal to twice the height of the grooves 2, the other tongue 12 will be of a height equal to the height of the grooves 2.
- the tabs 11 and 12 can be manufactured directly in these sections or can be cut on the site in panels of standard sizes of commerce.
- the implementation is similar to that of the shuttering blocks or certain formwork blocks, but with a pour of concrete at each row to ensure good filling of both vertical and horizontal stiffeners. [001 19]
- the implementation chronology is as follows:
- Cutouts 19 can easily be made to marry the blocks in a particular arrangement as illustrated in FIG. 22.
- Nails suitable for fixing foam material can be used in addition to an ordinary maintenance by rulers or pieces of wood clamped by screw presses during the casting of the concrete.
- blocks can thus be produced from a width L2 of 28 cm, then varying from 2 to 2 cm in addition for example, ie 30 cm, 32 cm, 34 cm, 36 cm or more.
- the construction process according to the invention is particularly intended for the production of exterior walls of single-family houses and residential buildings and, more generally, of all premises requiring an interior comfort temperature linked to human activity.
