Abstract

The subject of the invention is a press device for obtaining a composite element made of compressed clay. It is constituted by the combination of a double successive distribution by hoppers 5, 5' into spaces of different volume provided on a sliding container 6 which slides and transfers the load into a mould subjected to the pressure of compression and extraction jacks. It is intended for the construction of the main works of a building, for coverings, pavings and other parts with built-in protection and decoration.

Description

 The object of the invention relates to a press device for obtaining a composite element of compressed earth.

 It is intended for the construction of the main works of a building, for cladding, paving and other parts with integrated protection and decoration.

 Until now, pressed earth elements were obtained mechanically with various mixtures of binders but not comprising a protective coating from manufacturing, after assembling the blocks and putting them in place, coat the raw surfaces with a coating whose stickiness left something to be desired.

 The press device according to the invention eliminates these drawbacks and makes it possible to obtain an industrially usable product comprising a resistant earth mass of support having undergone high compression, but using in the same operation a protective stratification with a coating incorporated in the same forming and using the same pressure of homogenization when the setting of the binder mixed with the earth begins as a means of integrating the protective layer.

 It is constituted by the combination of a successive double distribution by hoppers in capacities of different volume - practiced on a sliding drawer and transferring the load in a mold subjected to the pressure of compression and extraction cylinders.

In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figures 1 and 2 show seen in elevation and in longitudinal and transverse section the press as a whole with the product obtained.

 Figures 3 and 4 show the construction detail and the operation of the mobile distributor drawer.

 Figure 5 is an overview of the press.

 The press, FIGS. 1 and 2, is constituted by the combination of a frame 1, of compression cylinders 2, 2 ′, of a cylinder guide 3, of a compression pad 4, of a movable drawer 6 moving on the guide rails 7, under the drawer is located the mold 8, the release pad 11 with stroke adjustment 12, 13, the release cylinder 14 is located in opposition to the compression cylinders.

 The drawer 6, Figure 2, 3, 4, is provided with receiving honeycombs 15, 16 of different volumes intended to receive the earth and coating loads distributed by the hoppers 5 and 5 '.

This same drawer moving in the direction of the arrows
A and B are used to extract the finished product 18.

 On either side of the drawer are the work tables 10, 10 '.

 The element 18 is obtained with a mixture of earth and cement 19 or of any suitable binder with an agent adapted to its destination and moistened after kneading. I1 occupies the cell 15.

 The coating product distributed by the honeycomb 16 during the translation of the mold arrow A. The return movement arrow B first distributes the product 20 at the bottom of the mold.

The earth mass 19 covers this stratification 20.

 The pressure cylinders 2, 2 'are then set in motion. They develop a power of around 40 tonnes, which allows a pressure adjustment of around 400 bars.

 After forming and integrating the coating 20, the release cylinder remounts the block which is brought by the face 17 of the drawer to the extraction console 21.

 There is thus a pressed earth construction element 19 automatically coated with an insulating, isothermal or impermeable protective lining, structuring and reinforcing it, also serving for its decoration, all in a single forming operation.

 The production rates can reach more than two hundred blocks per hour, it being specified that during the automatic compression and demoulding operation, the operation can free the block from the work station 21 which accelerates the yield.

However, the shapes, dimensions and arrangements of the different elements may vary within the limit of the equivalents, like the materials used for their manufacture,
without changing for that, the general conception of the invention
which has just been described.

Claims (1)

CLAIMS 1 Press device for obtaining a composite element in compressed earth intended for the construction of the main works of buildings, for coatings, pavements and others, making it possible to obtain an industrially usable finished product having undergone in the same compression operation , the homogenization of the support and the integration of an isothermal, soundproofing or waterproofing coating for the uses of pressure at the same time as the setting of the binder of the support as a means of strengthening adhesion cohesion, being characterized by the combination of a frame (1) of compression cylinders (2, 2 ') of a compression pad (4), of a movable drawer (6) of a guide (7) of a mold ( 8), a release pad (11) with guide (12,  13) a release cylinder  (14).  20 Device according to claim 1, characterized in that the sliding drawer (6) comprises two receiving holes (15, 16), volumes of soil (19) and of coating (20) distributed by the hoppers (5, 5 ').  30 Device according to claim 1, characterized in that the block obtained formed by the earth mass mixed with the binder (19) and by the integrated lining (20) are distributed after forming on the extraction surface (21) by the face (17) of the drawer forming a pusher and which moves on the brackets (10, 10 ').
