Abstract
A frame support holds an extendable and retractable cylinder on which a tile engaging device is mounted. A vibrator is combined with the tile engaging device. In operation, when a tile is to be tested for adhesion on its base and expected life-span the frame support is placed on a tile surface, the cylinder is extended with the tile engaging device against a selected tile. When the tile is engaged, vibration thereto is initiated for a predetermined time and at a predetermined rate. The cylinder is retracted and the force used to pull the tile is an indication of the strength of the bond between the tile and the adhesive and between the substrate and the adhesive, so that the life-span of the laid tile can be determined based on the measured force which is used to pull the tile.
Description
7 ~ ~
This inven-tion relates to an apparatus for testing tiles. More specifically, the presen-t invention is concerned with an apparatus for individually testing the adhesion or bond of a plurality of tiles which a;re fixedly moun-ted on a base, such as a floor, in order to determine if the tile has sufficient life-span. In particular, the invention relates to a method and an apparatus to test any laid tile for -the strength of the bond formed between the tile and the adhesive so that the life-span of the laid tile can be determined based on the measured force displayed when removing a tile by the method and apparatus according to the invention.
Presently, there is no method generally available enabling to determine whether the bond between the tile and the adhesive and between the substrate and the adhesive which makes a tile adhere to a substrate such as a floor is satisfactory or in good condition, in a sense that the laid tile has the expected life-span. This is important, because in today's construction, the adhesion with which a tile adheres to a base, although it mus-t be of excellent condition, may vary depending on the use which the tile surface will endure, especially pedestrian traffic which may vary substantially depending where the tile is laid.
There is therefore a need to provide a method and/or a device which is efficient, reliable and not too expensive, to test any laid tile for bond strength so as to determine its life-span under specific conditions of use.
In accordance with the invention, there is provided an apparatus for individually testing the adhesion oE a plurality of tiles which are fixedly 2~3~i7~2 moun-ted on a base to consti-tute a tile su.rface and for determining the expected life-span of said tiles, said apparatus comprising:

means downwardly operating said holding means to cause engagement of said suction means with said individual tilei first switching means to operate said suction means to cause firm engagement thereof with said individual tile;
second switching means to cause said vibrator means to initiate vibration of said suction means;
means upwardly operating said holding means until said tile is removed; and means measuring force used to remove said tile.
In accordance with a preferred embodiment, the frame support comprises a pair of vertical members intended to rest on the tile surface and a transverse horizontal member fixedly mounted on the upper portions of the vertical members, the holding means being retained by the transverse horizontal member.
The holding means preferably comprises a hydraulic cylinder which is mounted on the transverse member.
iJ3 rj~ ~ 2 In accordance with another preferred embodiment, the apparatus comprises a hydraulic pump operatively connected to the hydraulic cylinder to operate same with an extension or retraction movement.
In accordance with another embodiment, the apparatus comprises a hydraulic piston provided on the hydraulic cylinder, the hydraulic piston being extendable and retractable at the outer end of the hydraulic cylinder.
In accordance with yet another embodiment, the suction means comprise a cup which is made of resilient material, such as rubber.
In accordance with yet another embodiment, the cup is mounted at the outer extremity of the hydraulic piston, and -the apparatus comprises a vacuum pump operatively connected to the cup to provide suction therein.
In accordance with yet another embodiment, the apparatus comprises a vibrator mounted on the piston in combination with the cup to cause vibration thereof when the vibrator is in operation.
In accordance with yet another embodiment, the apparatus comprises a pressurized air circuit adapted to be connected to a supply of air under pressure, the pressurized circuit to operate the vacuum pump and the vibrator.
The invention also relates to a method for individually testing the adhesion of a plurality of tiles which are fixedly mounted on a base to constitute a tile surface, which comprises applying a suction device against upper surface of a tile whose adhesion to said base and expected life-span are to be determined, 2~a~r~
providing sufficient suction in said suction device to enable said suction device to hold said tile after having exert:ed a pulling force away from said base, producing a vibration in sai~ suction device at a predetermined rate, and for a prede-termined period of time, and thereafter exerting said pulling force away from said base, and measuring the force used to pull said tile away from said base which determines said life-span under estimated pedestrian traffic.
The invention is illustrated but not restricted by the annexed drawings of a preferred embodiment in which:
The single FIGURE is a schematic illustration of an apparatus according to the invention.
With reference to the drawings, it will be seen that the apparatus 1 according to the invention is intended to test the adheslon and expected life-span of the tiles 3 which are bonded in known manner on a floor 5, to constitute a tile surface.
The apparatus which is schematically illustrated comprises a frame support which is made of a pair of vertical members 7 and 9. These vertical members are designed so that their lower ends can rest on the tile surface by sitting in a suitable manner on any appropriate tile or tiles 3.
The two vertical members 7 and 9 should be sturdy and strong enough to hold the remaining part of the apparatus 1. To complete the frame support, a transverse horizontal member 11 is fixedly mounted in known manner, such as by means of attachment devices 13,15 at the upper portions of the vertical members 7 and 9. In the assembled position of the frame, the transverse horizontal member 11 is spaced from the 7'~ 2 tile surface a predetermined distance a which is sufficient for mounting -the equipments which will be described hereinbelow.
A hydraulic cylinder 17 is mounted on the traverse vertical member 11 half way between the two vertical members 7 and 9 so that the lower part thereof projects substantially below the transverse vertical member 11 all as shown in the drawings. The specific design and mounting on the transverse horizontal member 11 of the hydraulic cylinder 17 form no part of the invention and are essentially left to the choice of the designer and builder of the apparatus.
The hydraulic cylinder 17 is connected via an oil circuit, represented here by an oil duct 19 to a hydraulic pump 21 of known construction. A
pressure gauge 23 is provided in known manner on the hydraulic pump 21 to measure the pulling force used by the hydraulic cylinder 17 to pull the tile 3 away from the floor. This pulling force determines the strength of the bond between the tile 3 and the floor 5.
In known manner, the hydraulic cylinder has a hydraulic piston 25 at the lower end of the hydraulic cylinder 17 and the piston is arranged to be retractable at the end of the hydraulic cylinder between an extended position shown in full lines and a retracted position not illustrated in the drawings.
The apparatus 1 also comprises a rubber cup 27 mounted in known manner at the outer extremity of the hydraulic piston 25. As shown, the cup is bell shaped so as to be able to engage an individual tile 3 whose bond strength is to be determined. The individual tile is of course selected from those forming the tile surface. An air operated vibrator 29 is also mounted in suitable manner at the lower 2 ~ 2 extremity of the piston 25 and is in combination with the cup 27 to cause the latter to vibrate when the vibrator 29 is in operation. The vibrator can operate at variable Erequency of impact depending on es-timated pedestrian traffic: over the tile. The higher the estimated -traffic, the higher the frequency which will be used. The rubber cup 27 is connected via an air duct 31 to a vacuum pump 33 which is sufficiently powerful to provide a strong suction in the cup 27. In order words, the suction should be strong enough to enable the hydraulic cylinder to pull the tile 3 from its underlying floor 5 when sufficient force is applied by the hydraulic cylinder.
To ensure the operation of the rubber cup 27 and vibrator 29 with pressurized air, there is provided a pressurized air circuit of which air duct 31 is a part an also including air ducts 35, 36 and 37, all being connected to a supply of air under pressure (not shown).
A switch 39 in the form of a valve is mounted along air duct 37 to initiate the operation of vacuum pump 33 which will enable to provide suction in the rubber cup 27 via duct 31. A second switch 41 also in the form of a valve is provided along air duct 35 to cause the vibrator 29 to initiate vibration of the cup 27 at a predetermined rate.
The nature of the vibrations to be produced by the vibrator 29 is of course dependent on the nature of the test to be carried out. The vibrations could vary from very slow to very rapid, all depending on the conditions of use, such as pedestrian traffic to which the tile surface will be subject. Adjustment of the vibration rate is made 3 ~
possible by providing a vibration regulator 43. This regulator is well known -to t:hose skilled in the art and forms no part of the invention.
Finally, the Eorce which is used by the hydraulic cylinder 17, to pull a tile 3 which has undergone a specific type of vibrations is determined by the pressure gauge 23 as indicated above.
The operation o~ the apparatus is as follows. The apparatus 1 is placed on a tile surface such as a floor covered with tiles, over a specific tile 3, with the rubber cup 27 against that tile.
The air supply is connected to the inlet valve 39 enabling air under pressure to circulate through the pressurized air circuit, and activate the vacuum pump 33 until the test is completed. The regulator 43 is adjusted to supply adequate air into the vibrator to provide a vibration in the rubber cup 27 at a predetermined rate. Switch 41 is thereafter opened and this will initiate a predetermined vibration in the rubber cup which has been firmly engaged over the tile by opening the inlet valve 39.
The vibrator is allowed to operate for a preselected leng~h or time. The vibrator is then turned off by closing switch 41. The hydraulic pump is thereafter operated at a sufficient pressure to pu-il a tile from its substrate. The hydraulic pump is thereafter shut down, the air inlet valve is closed and the apparatus is moved to the next tile.
While the tile is being removed, gauge 23 will give an indication of the measure of the force applied by the cylinder to remove the tile. Such force will be used to calculate the bond strength between the tile and adhesive and between the substrate and the adhesive. The estimated pedestrian 7 ~1 ~
traEfic being known, and this factor having been reproduced by the vibrator, the bond strength will indicate whether the tile has been properly la.id.
Although the inven-tion has been illustrated by means of one embodiment" modifications are of course possible and permissible. For example, the cup may be replaced by any ti.le engaging device, the components may be operatecl by other means than pressurized air, the hydraulic pump may be replaced by any suitable pulling device.
