Title:
ATTACHMENT INCLUDING NAIL AND PRESTRESSING ELEMENT
Document Type and Number:
Japanese Patent JP3811514
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent an attachment from slanted installation in a foundation material and the foundation material from being damaged by providing the attachment easily and surely installable in the foundation material by using an explosive powder operating type installation device.
SOLUTION: An attachment installed in a foundation material comprises a nail 1 and a prestressing element 2. The prestressing element 2 is useful to assure the complete fixed condition of the nail 1 without accompanying a variation in installation depth. In order to enlarge a contact area, the prestressing element 2 is surrounded partially by a plastic part 3. By this, an inherent surface pressure caused when the element touches the foundation material is lowered, and the attachment is prevented from being installed aslant into the foundation material. In addition, a recessed part 3b is formed in the plastic part in order to accurately support an attachment guide member 4 by the prestressing element 2 in an explosive powder operating type installation device.
