Kind Code:
A1
Abstract:
Provided is an anchor bolt capable of reducing labor involved in assembly etc., even if a bolt body is long. This anchor bolt (1) is anchored in a hole (3) in a wall (2) made of concrete or the like, and has a tapered member (8), which forms an internal thread (7) that screws together with an external thread (4) of a bolt body (5), and an expanding member (9) that fits externally on the tapered member (8). The expanding member (9) has two contact sections (12) connected by a bridge section (13). An inclined surface (10) of the tapered member (8), and inner surfaces (14) of the contact sections (12), which come into contact with the inclined surface (10), are inclined in such a manner as to approach the central axis of the bolt body (5) toward the base end side of the bolt body (5). The tapered member (8) is divided into two tapered pieces (8a, 8b), and by inserting the bolt body (5) inside tapered pieces (8a, 8b) while open and then closing the tapered pieces (8a, 8b), the internal thread (7) of the tapered member (8) screws together with the external thread (4) of the bolt body (5). The closed tapered pieces (8a, 8b) are locked by a lock pin (26).
