Claim:
Accessory in combination with modular elements for the support and ventilation of crawl spaces, floor structures, or floors, wherein each one of said modular elements comprises an upper horizontal wall and a plurality of vertical supporting legs, and wherein the lateral profiles of each pair of said vertical supporting legs define a corresponding lateral aperture for obtaining a continuous passage below said upper wall, said accessory comprising a front wall and at least a lateral wall connected to said front wall and having-substantially the same shape of said lateral profiles of each pair of said vertical supporting legs of the respective modular element, whereby said front wall and said lateral wall are able to selectively close said lateral aperture of the modular element, the position of said lateral wall with respect to the lateral profiles of each pair of said vertical supporting legs of the modular element being selectively variable for consequently varying the distance between said front wall and said modular element, whereby said accessory is able both to close said lateral aperture of the modular element and to act as an extension element for said modular element, wherein said front wall is inclined by about 5°-15° with respect to a vertical plane.
