ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to building and more particularly a method of laying floor tiles and/or coverings allowing the same to be pulled up quickly in case of their replacement, and means for carrying out such method as well.
BACKGROUND OF THE INVENTION
Destructive operations of coverings and floors tiled with majolica and the like and, if necessary, also the demolition of the floor foundation are currently needed in case of replacement thereof. In such case electric or pneumatic chisels and/or hammers are used causing discomfort as far as noise, dust and rubbles is concerned.
Another problem of the common techniques of pulling up floors and/or coverings is the considerable labour and time needed for such work with the result of an increase in the total cost.
SUMMARY OF THE INVENTION
One object of the invention is to overcome the above-mentioned problems relative to the demolition of floors in order to reduce dust and noise caused by the pulling up of tiles.
A second object of the invention is to strongly reduce the time needed for pulling up the tiles to be replaced.
A third object of the present invention is to allow tiles to be replaced without removing the floor foundation.
Such objects are accomplished by sticking the tiles to a supporting bed to be anchored in a removable way to a fixed support conjugated thereto which is secured in a not removable way to the floor foundation.
A better understanding of the invention will result from the following description with reference to the sole accompanying drawing which shows a preferred embodiment only by way of a not limiting example.
