Abstract

Настоящее изобретение касается анкерного болта (1) для заделки в канал (2) шпура, содержащего удлиненную поглощающую энергию часть (4), первый конец (11) поглощающей энергию части (4), содержащий анкер (12), и второй конец (15) поглощающей энергию части (4), содержащий винтовое соединение (16) для создания предварительного напряжения анкерного болта (1). Анкерный болт (1) содержит удлиненную трубчатую часть (3) с кожухом (7) и первый концевой участок (5), а также второй концевой участок (6) с внутренним размером, который больше наружного размера поглощающей энергию части (4), и выполненную таким образом, что она окружает поглощающую энергию часть (4). Изобретение касается также способа изготовления такого анкерного болта.The present invention relates to an anchor bolt (1) for embedding a hole in a channel (2) containing an elongated energy absorbing part (4), a first end (11) of the energy absorbing part (4) containing an anchor (12), and a second end (15) the energy absorbing part (4) containing a screw connection (16) for creating a pre-stressing of the anchor bolt (1). The anchor bolt (1) contains an elongated tubular part (3) with a casing (7) and a first end portion (5), as well as a second end portion (6) with an inner dimension that is larger than the outer dimension of the energy absorbing portion (4), and in such a way that it surrounds the energy absorbing part (4). The invention also relates to a method for manufacturing such an anchor bolt.
