Definitions
- the invention relates to the manufacture by molding of a straight cylindrical body from a curable granular composition.
- straight cylindrical designates the shape generated by a so-called “generating line” which moves parallel to itself by following a so-called “directing” curve situated in a plane perpendicular to the right.
- This director is circular in the simplest case, but the invention is not limited to this profile and extends to any form of director.
- the body therefore has a constant cross section in a plane perpendicular to the direction of the length of the body.
- the invention applies in particular to the manufacture by molding of a pipe from a curable cement or ceramic composition, without however being limited to this application.
- curable cementitious compositions which consist of relatively fine materials and have a very low water / cement weight ratio, in particular a weight ratio of less than 0.16.
- compositions have very advantageous mechanical characteristics.
- the publication US 5,545,297 describes the manufacture of a straight cylindrical pipe from a cement composition in which the composition is passed in the pasty state into the molding cavity of an extruder, with an extrusion pressure the higher the lower the proportion of water relative to the cement in the composition.
- the publication EP 0 406 612 describes a technique for manufacturing a straight cylindrical pipe in which a granular cement composition is gradually poured in the loose state into a vertical molding cavity having the shape of the pipe to be obtained and is submitted to the cavity with the action of a vibrating wall generating radial forces and vertical forces directed upwards.
- the present invention relates to an industrial manufacturing technique by molding a straight cylindrical body, in particular a pipe, from an initially loose granular composition, not requiring the use of high pressures or the setting using such a vibrating wall and which is nevertheless suitable for molding a curable cementitious composition containing only a very small proportion of water.
- a straight cylindrical molding cavity having the dimensions in cross section of the cross section of the body to be manufactured is used and this cavity is supplied with a controlled flow of successive charges of the composition in the loose state, so that at any time the composition in place in the cavity has a free surface there and that each new charge is deposited on an area of this free surface, and each new charge is pushed into said surface to cause interpenetration of the new charge and of the composition underlying said surface, by means of pushing surfaces which are moved on the one hand in a reciprocating movement directed towards said free surface and in the opposite direction and, on the other hand, according to a cyclic movement such that the pushing surfaces are displaced in the extent of the free surface, and simultaneously during molding, a relative displacement of the molded composition is carried out and pushing surfaces so as to maintain substantially constant the distance between the mean point of the movement of the reciprocating movement of the pushing surfaces and said free surface, said charge flow being controlled so that, during each cycle, the material on which the charges are deposited is gradually densified in depth by the cumulative interpenet
- the interpenetration is carried out so that at each elementary stroke of a thrust surface, the underlying composition is interpenetrated to a depth at least equal to five times the average diameter of the granular class of the largest constituents of the composition.
- composition contains fibers or other similar reinforcements, the dimensions of these constituents are not taken into account for the determination of the penetration depth.
- the maximum penetration depth is limited to ten times this average diameter.
- the conditions will preferably be regulated so that the interpenetration occurs over a depth of 5 to 10 times the average diameter grains of sand, for example a depth of 1.5 to 3 mm if this average diameter is 0.3 mm.
- charges of loose material are deposited simultaneously on several non-contiguous zones of said free surface.
- the process is preferably carried out continuously, that is to say, by supplying the charges continuously, it is also possible to operate discontinuously.
- a plurality of separate thrust surfaces are used to push the loads; the charges are introduced between the thrust surfaces;
- - Said cyclic movement is a rotational movement; - Performing said relative movement by evacuating through the molding cavity the molded composition as in a die, as and when molding; said relative displacement is carried out by displacing the thrust surfaces, as the level of the molded composition rises in the molding cavity; said relative movement is achieved by simultaneously moving a wall of the mold cavity and the thrust surfaces; a pressure lower than atmospheric pressure is produced to degas the charges before pushing them; a phase shift is made between the back and forth movements of the different thrust surfaces.
- the material is allowed to harden before demolding or after demolding, as the case may be.
- a composition consisting of fine powders is preferably used, for example, a composition such as the composition of the concrete matrix defined in the publication FR 2 707 625.
- a device which comprises: a mold which determines a straight cylindrical molding cavity which has a cross section of shape identical to that of the body to be fabricate and which extends along an axis perpendicular to the plane of this cross section, over a length equal to a fraction or to the entire length of the body to be manufactured; introduction means for introducing a controlled flow of charges of the loose composition in the direction of said cavity; thrust means which determine a plurality of separate thrust surfaces distributed around said axis and directed towards the plane of the cross section of the mold cavity; - control means for causing a displacement of the thrust surfaces on the one hand according to a back-and-forth movement directed along this axis and, on the other hand according to a cyclic movement around said axis; and control means for carrying out, during the molding, a relative displacement of the molded composition and of the thrust surfaces, as a function of the rate of introduction of the loose material, so as to maintain substantially constant the distance between the mean
- the introduction means are designed to introduce the charges between the thrust surfaces;
- the molding cavity constitutes a die through which the molded material is pushed;
- the mold cavity is determined by an interval between two walls, one of these walls being movable with the thrust surfaces to achieve said relative displacement;
- the mold is fixed and the pushing surfaces are movable to achieve said relative displacement;
- the pushing surfaces are such that there exists between them and the walls which determine the molding cavity a lateral gap which allows a release of part of the material of the loads under the effect of the displacements of the pushing surfaces;
- the thrust surfaces are preceded in the direction of said cylindrical movement, by inclined surfaces for pre-compacting the loads.
- FIG. 1 is a schematic axial section of a device in accordance with the invention reduced to its essential parts;
- Figure 2 is a diagram showing details of the device of Figure 1, in axial section;
- Figures 3 and 4 are schematic perspective views which show the device of Figure 2, respectively seen in an oblique direction at 45 ° downwards ( Figure 3) and seen in an oblique direction at 45 ° upwards ( Figure 4) starting from the eye of the observer.
- - Figures 5 to 7 are diagrams of devices according to different embodiments of the invention. The mold shown in FIG.
- a rotor (5) which carries a plurality of pushing tools (6) identical to each other and separated by constant intervals. Respective means (not shown) are used to drive the tools respectively in a cyclic movement around the axis (2) of the molding cavity, in the direction of the arrow (8) and in an alternating movement along the arrow ( 9) parallel to the axis (2) of the molding cavity.
- Means shown diagrammatically by the arrows (10) are present for introducing charges of loose material between the tools.
- a frustoconical wall (13) is provided above the internal wall of the mold (3).
- FIGS. 2 to 4 parts of the device in FIG. 1 are shown, on a different scale, in order to make the tools appear better, apart from their common support.
- the tools are shaped to have a lower end (6a) which has a face (11) turned downwards to push the loose material towards the free surface of the material already in place in the mold when the tool is moved downwards and a face (12) turned in the direction of rotation according to arrow (8), which precedes the pushing face in the rotary movement of the tool and which is capable of precompacting the load of loose material.
- these two faces help push the filler material into the molded material.
- they together form a convex surface. They are themselves flat or curved.
- FIG. 2 the tools are shown in the low extreme positions (solid lines) and high (broken lines) of their reciprocating movement.
- the reciprocating movement of the thrust surfaces is preferably adjusted with a fairly high displacement frequency, typically from 5 to 50 reciprocating per second, even better from 10 to 30 reciprocating by second.
- a lateral gap T
- the figures represent different possibilities for driving the tools and for carrying out a relative displacement between the molded material and the tools as the molded material increases: in the case of FIG. 1, the outer wall (1) of the mold is fixed and its inner wall (3) is moved upward during molding at the same time as the tools.
- the mold comprises a core (17) whose lower part is shaped to constitute the wall (3) of the mold, this core carrying the tools (6) so that they can rotate around the core (arrow 8) and rise or fall (arrow 9); the core itself is moved upward (arrow 18) during molding.
- the mold is progressively moved away from the tools during the molding in the direction of the arrow (19), the tools remaining stationary (except of course their two functional movements back and forth and rotation) .
- the mold functions as a die and its bottom wall (14) is moved
- a loose, dry and pulverulent material is essentially prepared by kneading the following constituents (for 10 kg of material): , 5 kg of sand with a grain size of about 0.3 mm
- the density of the loose material is between 1 and 1.5.
- a vertical mold is formed with two coaxial cylindrical walls having diameters of 120 and 100 mm respectively and a bottom wall, using the central wall of the mold to carry four pushers shaped according to the invention; a fraction of the loose material is poured into the bottom of the mold until it forms a ring over a height of a few millimeters; each pushing tool is driven with a vertical reciprocating movement of 15 strokes per second over a vertical stroke of 10 mm, the reciprocating movements each being phase shifted by a quarter of a cycle, and with a rotary movement of 1 revolution per second, while supplying the free surface with a volume flow of
- the material is allowed to harden in the mold and is demolded.
