Definitions
- the present invention relates to a method for adjusting, to a predetermined height, the height of building blocks and the like, in particular of concrete blocks intended to be laid dry on each other and to be filled or not with a binder, according to which blocks are deposited on the upper faces of a quantity of a material, which can harden and be fixed on the latter, such as cement, of a height which is greater than the difference between the predetermined height above and the actual height of the block in question and this quantity of material is flattened on said faces before the latter hardens until the total height of said block, formed by the sum of the height of the latter and that of this quantity of material, corresponds substantially to the predetermined height.
- a quantity of a material which can harden and be fixed on the latter, such as cement
- the present invention aims to provide a method of the above type which can easily adapt to all known methods for the manufacture of building blocks, in particular concrete blocks in a static press.
- the method according to the invention successively comprises the formation in a mold of blocks whose height varies between the height
- the deposition on the unhardened and still wet blocks of a quantity of the abovementioned material, the height of which is greater than the difference in height between this predetermined height and the actual height of the block in question and the flattening of this quantity of material until the total height of said block, formed by the sum of the actual height of the latter and that of the quantity of material corresponds substantially to the predetermined height, the blocks moving in a substantially continuous manner at least from their exit from the molds until the aforementioned deposition of the material on the blocks.
- the invention also relates to a positive device for the implementation of this process, that is to say a device for adjusting the height of building blocks and the like, in particular of hollow blocks intended to be laid dry one on the other. on the others, comprising a metering device for depositing on the upper faces of the blocks a quantity of material which can harden and be fixed on the latter and an equalizing device for flattening this material on the blocks so as to give the latter a height total corresponding substantially to a predetermined height.
- a positive device for the implementation of this process that is to say a device for adjusting the height of building blocks and the like, in particular of hollow blocks intended to be laid dry one on the other. on the others, comprising a metering device for depositing on the upper faces of the blocks a quantity of material which can harden and be fixed on the latter and an equalizing device for flattening this material on the blocks so as to give the latter a height total corresponding substantially to a predetermined height.
- This device is characterized in that it comprises a conveyor for the blocks extending from a press in which the blocks are formed and moving in a substantially continuous manner through the equalizing device, a leveling element above an es- the space in which said blocks are brought by the conveyor to flatten the material deposited on the blocks by the metering device, and spacing or guide members making it possible to maintain the above-mentioned element, at a relative distance from the underside blocks corresponding substantially to the aforementioned predetermined height, during the flattening of the material deposited on the blocks.
- the leveling element comprises at least one substantially horizontal cylinder, actuated so that each point of the cylindrical surface generates a cycloidal curve relative to the blocks, that is to say rolls, without sliding , on the material deposited on these.
- the spacing or guiding members are fixed relative to the leveling element and cooperate with a plate or board carrying the blocks to be adjusted when the cylinder is found in its low position, that is to say near the upper surface of these blocks, the distance separating the part of the leveling element intended for flattening the material on the blocks of the part of the spacer or guide member intended to cooperate with a plate or board carrying the blocks to be adjusted is substantially equal to the total predetermined height of the blocks.
- the invention relates essentially to the manufacture of concrete blocks and especially of light concrete blocks, for example with a base of expanded clay, having at least one hollow passing right through the blocks over the entire height and which can be assembled at dry so as to form ash channels in which a binder can be poured, in particular concrete.
- a quantity of material is deposited on the upper faces of the blocks, which can harden and become fixed on the latter, preferably a product based on cement and in particular pure cement, of a height which is greater than the difference between a predetermined or prescribed height and the actual height of the block in question, and to flatten, at least partially, this material on said faces before hardening thereof until the total height of said block corresponds appreciably to the predetermined height or prescribed, this total height being formed by the sum of the actual height of said block and that of this amount of flattened material.
- This material is deposited on the blocks as soon as they leave the press, that is to say before they are dry, so that this material can harden and become fixed to said blocks, at least partially due to humidity held in the same blocks.
- At least four small heaps, cone-shaped, are formed on the upper edges of the material.
- this quantity of material is flattened, in particular by means of a roller or cylinder, until the total height of said blocks, formed by the sum of its actual height and that of the quantity of material , correspond-
- the blocks In a final stage, "the blocks thus adjusted in height are subjected to drying and hardening.
- the blocks move in a substantially continuous manner at the outlet of the press andluate preferably as well during deposition heaps of the material on the upper surface of the blocks than during the flattening of these heaps.
- These blocks are in particular formed in the static press on platens, called boards, which, at the exit of the press, move on a conveyor formed by two endless parallel chains driven by a continuous movement.
- This method therefore has the advantage that it does not slow down the production of blocks in the static press, the operations of depositing the material on the blocks and the operation of flattening this material preferably being carried out without inter ⁇ break in the advancement of the plates carrying the blocks emerging from the press.
- the aforementioned flattening is carried out advantageously by means of a rolling cylinder, without sliding, above the blocks, at the above-mentioned pre-finished height.
- the appended figure shows schematically a particular embodiment of a device making it possible to apply the method described above.
- This device essentially comprises a metering device 1 for depositing on the upper faces of blocks 2 a quantity of a material in the form of cones 3 and an equalizing device 4 for flattening these cones on the blocks so as to give the blocks a total height corresponding substantially to the aforementioned predetermined or prescribed height.
- This device is mounted at the outlet of a static press, not shown, for the. manufacture of concrete blocks.
- the metering device 1 and the equalizing device 4 are mounted in series on the same rigid frame 5 so as to form a one-piece assembly.
- the metering device comprises a hopper 6 with an inclined bottom 7 intended to contain the powdery product, in particular cement, to be deposited on the blocks.
- This hopper has at its lowest part a series of orifices 8 each cooperating with a separate closing member 9 making it possible to adjust the quantity of product passing through each of these orifices.
- This metering device 1 is preceded by a cylindrical brush 10 suspended from the frame 5 at a height adjustable by screw rods 11.
- the equalizing device 4 comprises a leveling element above a space 12 in which the blocks 2 can be brought to flatten the cones 3, deposited on the blocks by the hopper 6 of the dosing device 1.
- spacers or guide members 13 are provided to maintain the element of
- This leveling element comprises, in the embodiment shown in the figure, three identical cylinders 14 whose axes extend in the same substantially horizontal plane. These cylinders are actuated around their axes, so that each point on their cylindrical surface generates a cycloidal curve relative to the blocks, that is to say rolls, without sliding on the material deposited on the latter.
- the equalizing device 4 also comprises a sliding frame 15 suspended, by means of screws 16 controlled by handwheels with handle 17, from a frame of the frame 5.
- the cylinders 14 are in turn mounted in a frame 19 which can undergo a downward and upward movement, as indicated by the arrows 20, relative to the frame 15, between a high position, in which the cylinders are in an inactive state, and a low position, in which the cylinders can accomplish the abovementioned flattening operation.
- This movement of raising and lowering of the chassis 19 takes place by means of bellows jacks 21.
- the spacing or guide members 13 are fixed relative to the chassis 19 carrying the cylinders 14 and cooperate with the plate or the board 22 carrying the blocks 2 to be adjusted when the cylinders are in their low position, that is that is, near the top surface of the blocks. This is the position shown in the figure.
- the spacing and guide members comprise wheels or rollers 23 mounted on the lower end of a vertical profile 24 welded to the chassis 19.
- These wheels or rollers 23 are, in the figure, two in number per cylinder 14 and extend on either side of the vertical plane of symmetry passing through the axis of a cylinder.
- Means are provided for adjusting the distance between the cylinders and the wheels or rollers.
- these means consist of machined shims 25 which can be placed between the lower end of the profile 24 and cushions ts 26 fixed on this. last and carrying the rotation shaft of the wheels or rollers 23.
- Such means could, for example, be used to adapt the distance separating the cylinders 14, in their low position, of the boards 22 with which the rollers or wheels 23 cooperate in this position.
- the wheels or rollers 23 freely rotate about their axis in the bearings 26, while the cylinders 14 are driven by by means of a geared motor 27 controlled by an incorporated frequency variator. This drive takes place via cranked belts 28 moving around pinions 29 mounted on the rotation shaft of the different cylinders 14.
- This drive is such that when the cylinders are in their low position, they can roll on the blocks 2 without sliding, that is to say so that each point of the cylindrical surface of the cylinders 14 generates a cycloidal curve.
- the blocks pass automatically and continuously below the openings 8 of the hopper 6 of the metering device 1 and cimei studs of conical shape 3 are deposited at very precise locations on the surface upper 32 of the blocks.
- the board 22 then passes, still in a substantially continuous manner, into the space 12 of the equalizing device 4.
- the frame 19 carrying the cylinders 14 is subjected to a downward movement by means of the jacks 21 up to when the wheels or rollers 23 meet the board and roll freely on the latter, this descent being for example of the order of 0.5 to 1 c.
- a blowing device 34 is provided on the frame 5 at the entrance of the space 12 to sweep this path of rolling.
- the movable frame 15 not only carries the chassis 19 but also the hopper 6. It is also important to provide an effective cleaning system for the rollers, for example squeegees, not shown, acting on the cylindrical surfaces of the cylinders at the time. where the latter are in the high position, that is to say their inactive position.
- plu ⁇ eral cylinders 14 are used, as in the embodiment shown in the Figure, to mount each roller on a frame 19 independent ordered separately so that the rollers or wheels 23 can only descend when a plane is below the corresponding cylinder.
- the spacing and guiding members could be replaced by a double conveyor belt between which are taken the longitudinal edges of the plates 22 at the time of their passage in the space 12 and in which the boards are kept at a constant distance from fixed supports against which the chassis 19 can abut in its lowest position, so as to be located at the aforementioned predetermined distance allowing the height of the blocks to be adjusted 2. It would suffice for example by providing a lower conveyor belt which makes it possible to apply the board against an upper conveyor belt moving in guide rails or else a rolling over the two longitudinal edges of the boards.
- Yet another variant consists in using a leveling element fixed in height, but comprising rollers undergoing translation in the direction of movement of the blocks, however providing for means of transport separate from the conveyor 30, the latter moving by a substantially continuous manner, which can temporarily release the boards of this conveyor 30 to maintain them for a short period of time in an immobile position at a well determined distance, corresponding to the above prescribed height, of the cylinders 14 when these the latter flatten the cones 3.
- a temporary stop could also be provided in the metering device.
- the aforementioned adjustment method is not. not necessarily limited to hollow blocks intended to be filled with concrete or any other binder, but may apply to any type of hollow block or not, which may preferably be laid dry on top of each other in a construction of wall.
