A skirt member that extends outward and sits on a steel plate is screwed together, and the skirt member is provided on the dowel body,
By seating this on the steel plate on the outer periphery of the dowel body, even if shearing or bending stress is applied to the steel plate or concrete layer, the skirt member will partially bear the load, and stress will not be concentrated at the base of the dowel body. It is designed to disperse stress and provide strong support.
［実施例］
以下、本考案に係るスタツドジベルの好適一実
施例を添付図面に基づいて説明する。[Embodiment] Hereinafter, a preferred embodiment of the stud dowel according to the present invention will be described based on the accompanying drawings.

考案のスタツドジベルＡを示す。スタツドジベル
Ａはジベル本体４からなり、その外周にねじ部５
が設けられ、このねじ部５に螺合するナツト状の
スカート部材６から構成される。 FIG. 2 shows the stud dowel A of the invention before being stud welded onto the steel plate 1. The stud dowel A consists of a dowel body 4, with a threaded part 5 on its outer periphery.
is provided with a nut-shaped skirt member 6 that is screwed into the threaded portion 5.

る位置に保持される。 The dowel body 4 has a protrusion 7 for stud welding to the steel plate 1 at its lower end, and a head 8 having a diameter slightly larger than the diameter of the dowel body 4 at its upper part.
The skirt member 6 has a seat 9 at its lower end that seats on the steel plate 1, and is screwed into the dowel body 4 from the lower part so that the seat 9 is held at a position sufficiently apart from the steel plate 1 before stud welding.

つても支障なく着座できる。 In the state shown in FIG. 2, the dowel main body 4 is stud welded 10 to the steel plate 1, and then the skirt member 6 is rotated so that its seat surface 9 is seated on the steel plate 1.
At this time, since the skirt member 6 is screwed onto the dowel body 4, the skirt member 6 is
Since the skirt member 6 is not in direct contact with the base of the dowel main body 4 and is separated from it when the dowel body is seated, the dowel body 4 can be seated without any problem even if there is weld overlay on the base.
このようにして鋼板１上に本考案のスタツドジ
ベルＡを多数植設したのち、第１図に示すように

を低くすることが可能となる。 When stress is applied to the steel plate 1, for example, as indicated by the arrow in the figure, the stress is also transmitted to the dowel body 4 via the steel plate 1. In this case, a skirt member 6 is provided around the outer periphery of the dowel body 4, and its seat surface 9 is seated on the steel plate 1. Therefore, even if the dowel body 4 tries to bend from its base, this skirt member 6 It is possible to disperse the load and prevent stress from concentrating on the base of the dowel body 4, and since the approximate center of the dowel body 4 is supported by the skirt member 6, it has extremely high bending rigidity. Moreover, the compressive stress transmitted to the concrete layer 3 is also dispersed, making it possible to lower the overall stress level.
