  • Publication number: 20100229496
    Abstract: A structural member joint structure can easily join members to each other by using a simple structure having a reduced number of parts and can provide the members with a large fastening force which makes the members less likely to be loosened from each other. The joint structure is used to join one pillar and the other pillar to each other such that the other member is vertically abutted against a side face of the one pillar. The structure has a pair of fastening members positioned in the inside of the other pillar and arranged so as to be movable in the widthwise direction of a groove formed in a side face of the one pillar, a nut mechanism located on the inward side of the other pillar and formed between the pair of fastening members, and a bolt operated from the outside through an opening in the other pillar to be fitted into the nut mechanism. Rotating the bolt causes the nut mechanism to urge and move the pair of fastening members in the direction in which the pair is separated from each other.

A portion of the cylinder's exterior surface adjacent to the first end is threaded for placing the insert in a hole in the recipient material and then stabilizing the insert therein. Additional stability is provided by the interface of a flange on the cylinder's second end with an adhesive which is placed in the hole with the insert. The flange is formed by a circumferential recess near the cylinder's second end. The adhesive occupies the recess and, when it hardens and bonds to the recipient material adjacent to the recess, serves as an circular barrier abutting the inner boundary of the flange. The barrier prevents the insert from being pulled from the hole.

  • Patent number: 4642964
    Abstract: Fastener systems for securing an object to the surface of structure, and methods for forming the same. Shafts of fasteners have threaded ends which are to be embedded in holes formed in the structure and which are filled with a securing agent. For greater pull-out resistance the holes can be enlarged at their internal ends, either by molding or by breaking out the walls of the hole ends with a special tool. A lubricant coating the inserted shaft end permits withdrawal of the fastener shafts. In one embodiment, the external end and the internal end of the shaft are reversely threaded. A cap nut on the external end has a compressible pellet therein. Initial threading downward of the cap nut tightens the nut more securely against the secured object, and further turning unthreads the fastener. A fixed head embodiment carries a cap at its internal end to prevent hardening securing agent from filling in under the shaft so that the shaft can be threaded deeper into the hole when the securing agent hardens.
