Description of the Related Art Conventionally, as a joining auxiliary member for a high-strength bolted joint of this type, a bolt hole is provided at a central portion, and a size of a maximum range affected by a tightening force of one high-strength bolt is known. On one surface of a circular plate-shaped member having a linear shape, a plurality of parallel linear blade-like projections with shoulders are formed over the maximum range in which the effect of the tightening force of one high-strength bolt is exerted. A single parallel high-strength bolt over the maximum range that is affected by the tightening force of a single high-strength bolt around the bolt hole at the joint surface to be joined to the base material of the joint fitting such as a base plate. It is known that a plurality of blade-shaped projections with shoulders are integrally formed (see Japanese Patent Application No. 5-280102). The former is such that the blade-shaped projections with shoulders are at right angles to the stress acting on the base plate and the like, and protrude above the bonding surface in the counterbore recess provided around the bolt hole in the joint surface of the base plate and the like. It is used by fitting a plate-shaped body, and the blade of each blade-shaped projection with a shoulder bites into the base material to the root by tightening the base material and the attachment plate with high-strength bolts, and the shoulder is inserted into the base material. coherent or reduced interrupt, slip strength of the line of action perpendicular direction of stress is obtained, also the latter,
The same operation and effect can be obtained by tightening the base material and the supporting plate with a high-strength bolt without performing any pretreatment process.

FIG. 1 is a perspective view showing an example of an embodiment of a joining auxiliary member for a high-strength bolted joint according to the present invention. The joining auxiliary member 7 for a high-strength bolted joint, as will be described later , applies a stress acting on the attached plate or the like to a joint surface around a bolt hole in an attached plate or a joint fitting joined to the base material by the high-strength bolt. (For example, tensile and compressive forces), which are fitted in a plurality of grooves provided in the direction perpendicular to the line of action of a single high-strength bolt over the maximum range in which the effect of the tightening force is exerted. It is formed of high-strength steel, stainless steel, ceramics, cemented carbide, cermet, or the like having a strength and hardness equal to or higher than that of the base material or the base plate. Then, the joining auxiliary member 7 is fitted into the groove having a wide trapezoidal cross section with the bottom surface provided on the joining surface of the attachment plate or the like, with the upper surface appropriately projecting from the joining surface, and tightening one high-strength bolt. have a straddle length to the maximum extent the effect of the force is exerted, and, the bottom surface
Is formed of a fitting portion 8 having a wide trapezoidal cross section , and one blade-like projection 9 having a triangular cross section integrally formed at the center of the upper surface of the fitting portion 8 . Here, the joining auxiliary member 7 has a thickness (height) of 1 to 20 mm and a width of the fitting portion 8 of 3 to 15 mm.
The angle of the blade-shaped protrusion 9 is 20 to 90 °, and the height thereof is 0.5.
It is preferable that it is 3.0 mm. On the other hand, the maximum range affected by the tightening force of one high-strength bolt is, for example, an outer diameter of about 40 to 90 mm in the case of a high-strength bolt diameter of 16 to 30 mm and a plate thickness of 12 mm of a base plate or the like. .

2. As shown in FIG. 3 , one high force is applied to the joint surface 10a around the bolt hole 11 of the attachment plate 10 made of a constituent material such as SS400 in a direction perpendicular to the line of action of the stress acting on the attachment plate 10. bolts are those influence of the clamping force across the添板10 exceeds the maximum range that spans provided with a bottom (not shown) is used to fit a plurality of grooves 12 of the wide cross-section trapezoidal, high power bolt
By tightening the base material (not shown)
Then, the blade-shaped projections 9 of the respective joining auxiliary members 7 reach the base of the base material.
The upper surface of the fitting portion 8 is closely attached to the base material or
Reduces and holds down the periphery of the bite-shaped protrusion 9
Therefore, while the joint surface of the base material is
The compressive force becomes a resultant force with the stress applied to the blade-shaped protrusion 9.
As a result, sufficient slip strength in the direction perpendicular to the line of stress
In particular, since the fitting portion 8 has a trapezoidal cross section,
Reduction of the base material (not shown) interrupt is Ru been effectively carried out. This
In this case, the side of the fitting portion 8 of each joining auxiliary member 7 is
Since there is no stress concentration on the side wall of the groove 12 that has been touched,
The auxiliary member 7 does not move. Note that the groove 12
The fitting of the joining auxiliary member 7 can be performed by cold fitting, full circumference welding, or groove.
12 is performed by caulking around the periphery.
