A circular column or a circular cylinder refers to a solid cylindrical structure or a hollow cylinder or a mixture thereof, and more specifically, a column, a pipe,
Refers to a pile or the like. Further, the male tapered cylinder and the female tapered cylinder provided at these connection ends are the same as the circular column or the circular cylinder, separate bodies connected by welding or the like, embedded in concrete or the like.

て強固に係合するようにしてもよい。The above annular joint is a joint in which a male tapered cylindrical body having a tapered taper and a female tapered cylindrical body which is fitted to the outside thereof are axially pushed and fitted. It is preferable that the male tapered cylinder and the female tapered cylinder have mating conical tapered surfaces having the same gradient as each other, but the present invention is not limited thereto, and the male tapered cylinder and the female tapered cylinder are It is also possible to have a mating conical tapered surface having a gradient that is different from the whole or partially, and for example, the pushing force may be increased so as to firmly engage.

It is good to set it in the range of 10/1/50. It is not easy to form a joint that is difficult to pull out with a gradient greater than 1/10,
When the gradient is smaller than 1/50, the surface pressure of the tightening surface (taper surface) fluctuates greatly due to slight fluctuation of the pushing force, which is not appropriate. The axial length of the male tapered cylindrical body and the female tapered cylindrical body is preferably about 0.5 to 1.0 times the average outer diameter of the conical tapered surface of the male tapered cylindrical body. Preferably, the minimum thickness of the male tapered cylinder and the female tapered cylinder is 3 mm or more. If the wall thickness is less than 3 mm, there is a problem such as deformation during processing or on-site handling, which is not preferable. Also, there is a problem that buckling occurs when the joint is tightened, and it is not effective as a joint.

によって接触面圧を調整することができる。The male tapered cylindrical body and the female tapered cylindrical body may have smooth conical tapered surfaces. The conical tapered surfaces are provided with circumferential ridges perpendicular to the axes of the male tapered cylindrical body and the female tapered cylindrical body, respectively. This circumferential unevenness can increase the resistance to escape when the cross-sectional shape in the axial direction of the cylindrical body is saw-toothed. In addition, the contact surface pressure can be adjusted by providing an axial slit on one or both tapered insertion end sides of the male and female tapered cylindrical bodies.

It is possible to transmit both the axial thrust and the rotational torque, and retains the function of preventing the detachment even if the taper is loosened. If a circumferential groove is provided on the tapered surface of the male tapered cylinder, and a set bolt fitted into the circumferential groove is provided on the female tapered cylinder, it will be a safety device for preventing removal. In this case, the set bolts can transmit the axial thrust, but do not transmit the rotational torque, and have a structure in which they can freely rotate with each other.

The backup cylinder is in close contact with the inner periphery of the male tapered cylinder. When the inner circumference of the male tapered cylinder is cylindrical, the outer circumference of the backup cylinder is cylindrical. It is appropriate that the backup cylinder is located at a thin portion of the male taper cylinder, a portion provided with a slit, or the like. Particularly, a portion provided with a slit cannot expect a tapered surface pressure. And ensure a strong bond.

Sometimes can be applied. Of course, it can be used as a joint between steel and concrete members, or as a joint between steel and concrete composite members. In the case of concrete, concrete can be backed up without providing a backup cylinder of the male taper member. In this case, a strong joint is formed due to a difference in elastic modulus between the steel cylinder and concrete. There are advantages that can be done.

圧ｐが生ずる。BEST MODE FOR CARRYING OUT THE INVENTION An annular joint of the present invention and a tightening jig thereof are connected by pushing male and female conical tapers into each other in the axial direction and penetrating them. When the inclination angle of the taper (the inclination angle with respect to the conical axis) is θ, the average diameter of the tapered surface is d, the effective length of the tapered surface in the axial direction is L, and the thrust P is applied in the axial direction to push the tapered surface. , A surface pressure p expressed by the following equation is generated on the tapered surface.

不均一にし、わずかな軸方向抜け方向の移動に対して、
抜け抵抗の減少を緩やかにすることなども考えられる。P = P / πdL · sin θ When the inclination angle θ of the taper is reduced, a relatively small thrust P
And a large surface pressure p can be obtained. When the surface pressure p becomes larger than the yield point of the material of the tapered surface, the surface is plastically deformed, so that neither the surface pressure p nor the thrust P increases and there is an upper limit. A frictional force is generated in the sliding direction of the surface by the surface pressure of the tapered surface, and a pull-out resistance is generated by an axial component of the frictional force. This resistance is
If the friction coefficient is 0.1, it is approximately 0.1P.
If θ is large, the contact pressure decreases sharply due to slight movement in the pull-out direction, and the frictional force decreases. Therefore, fixing by only the pull-out resistance due to friction cannot secure reliability depending on the inclination angle of the taper. In addition, since a material receiving a load generally undergoes relaxation of the stress with the passage of time, another measure is required to ensure the detachment resistance.
For example, it is effective to provide unevenness on the tapered surface or roughen the contact surface. However, for example, the inclination angle θf of the female taper is set to a value slightly smaller than the inclination angle θm of the male taper. When the joint is inserted, the surface pressure of the thin part of the female tapered cylinder reaches the plastic region of the material, makes the surface pressure distribution non-uniform, and moves slightly in the axial direction.
It is also conceivable to moderate the decrease in pullout resistance.

することができる。Providing a circular ring-shaped concavo-convex strip perpendicular to the axis on the tapered surface is effective in preventing slipping. At this time,
When the tapered surfaces come into contact with each other at the ridges, the contact area is small, so the surface pressure becomes extreme pressure, the contact surface yields, and a hoop tension is generated in the female cylinder body, and the pushing further proceeds and the tapered surface When the concave and convex portions come into contact with each other, the extreme surface pressure is eliminated, and the contact area is increased and the surface pressure is reduced. Depending on the dimensions, the contact pressure may be zero. At this time, the detachment resistance is resisted by a large force because the ridges mesh with each other. If the size and arrangement of the ridges are appropriately determined, the value of the pull-out resistance can be set to a value that is approximately similar to the thrust P. When the shape of the above-mentioned ridge is formed in a sawtooth shape in which the cross-sectional shapes in the axial direction are meshed with each other, it is possible to impart a greater resistance to removal.

果を奏し、産業上寄与するところが大であるThe annular joint of the present invention is constructed as described above. For example, when this is used for connection of piles, it is easily connected by setting and pushing the upper pile on the lower pile. Therefore, an appropriate thrust can be applied, and a pull-out resistance can be appropriately given, which is extremely useful for simple and quick construction without welding or the like. In addition, a joint such as a pipe can be connected with good sealing properties. In some cases, there is an excellent effect that a structure having various characteristics with respect to transmission of rotational torque, thrust, and the like can be obtained, which greatly contributes to industry.
