ABSTRACT:
DESCRIPTION
The present invention relates to a device for anchorage to a grating floor, particularly applicable to floors having gratings for the passage of fluids or substances to be collected below the said grating as is the case, for example, for gratings for farms and the like.
The object of the device of the invention is to solve the problem which arises when screwed anchorages are required on grating floors since, given the dimensions and weight of the gratings and their fixed installation, access to their lower sides is difficult.
The purpose of the device of the invention is to enable one person alone to perform the anchoring without requiring access to the lower side of the grating.
To fulfil its purpose, the device of the present invention comprises an element the geometry of which allows the element to be introduced into an opening in the grating and, after the element has pivoted through 90°, prevents its removal. This element may have various designs according to the type of grating on which it is to be installed. On its lower face, the element has a cavity in which a nut is housed with the necessary pressure. In two of its lateral faces, the element has respective housings in which studs can be located and, above the said studs, the element has respective guide regions.
There is also a further element which has the purpose of securing and orienting the first element and which is constituted by a rectangular top portion of a width larger than that of the openings in the grating. Two legs of a width smaller than that of the openings in the grating extend from the lower side of this top portion and have, in their lower portions, respective studs arranged to be introduced into the housings of the first element. On the same face as the studs, there is a set of saw-teeth which can mesh with the toothed regions situated above the guide regions.
