。Conventional insulation support rod (1) configured as above
Problem 7 was that the rod (1) could easily be pulled out from the joint fitting (2) due to shear failure at the part between the right glass fiber (Eia) and the outer glass fiber (6b) under a low tensile load.
本発明は右側と外側の繊維の間の部分が剪断破壊しない

提供することを［］的とする。An object of the present invention is to provide a method for manufacturing a heat insulating support rod that prevents shear failure of the portion between the right side and outer fibers and has excellent mechanical strength.
本発明においては、テーパ部を半割れ金具に引掛けるの
みでなく、テーパ部（８）の勾配Ｙ／Ｘを１／ｌ。In the present invention, not only the tapered part is hooked on the half-split metal fitting, but also the slope Y/X of the tapered part (8) is 1/l.

するものである。After press-fitting the tapered part of the rod into the half-split metal fitting by pulling or pushing the rod in the central axis direction with a force greater than the supporting load but not damaging, the tapered part returns from the half-split metal fitting. By pressing the tip of the bolt against the end of the rod and applying compressive force in the radial direction between the glass fiber on the right side and the glass fiber on the outside to prevent it from coming out, the shear fracture strength between both glass fibers is increased. do. By setting the slope Y/X to 1/30 or more, the tightening force acting in the radial direction of the tapered portion of the rod is limited, and the tapered portion is prevented from gradually becoming plastically deformed due to the tightening force. This prevents the metal from gradually pulling out from the joint fitting (2) due to plastic deformation, and prevents the interval between the joint metal fittings at both ends from changing over a long period of time.

This half-split metal fitting (3), cylindrical metal fitting (4), and bolt (5) are collectively referred to as a joint metal fitting (2). Fix the cylindrical metal fitting (4) to a fixing member (not shown), and pull or push it in the direction of arrow M with a force that is greater than the support load of the support rod and does not cause damage to the rod (1), to tighten the tapered part. Half-split metal fittings (

している。FIG. 2 shows the relationship between the fracture strength of the tapered portion (8) and the slope, and the relationship between the slope and the change in the spacing of the joint fittings (2) when the joint fittings (2) at both ends are repeatedly pulled. Further, the solid line shows the result when the tapered part (8) is press-fitted into the half-split metal fitting (3), and the broken line shows the result when it is not press-fitted. As shown in this result, when press-fitting, the slope is reduced to 1/10
It can be seen that if the slope is set below, the breaking strength can be maintained at about 80% or more, and if the slope is set to 1730 or more, the change in the spacing between the joint fittings (2) is almost zero. This effect is particularly remarkable compared to the broken line curve in the case of no press fitting, indicating that it exhibits excellent performance as a heat insulating support rod.

利点がある。As explained above, according to the present invention, both ends of the fiber-reinforced plastic rod are tapered outward, the slope of this taper is set to 1730 to 1/10, and the tapered part is sandwiched between half-split metal fittings (3). This was held with a cylindrical metal fitting, and the rod was pulled or pushed in the direction of the central axis with a force greater than the supporting load but not damaging the rod, and the tapered part was press-fitted into the half-split metal fitting. It stably increases the shear fracture strength of the portion between the eccentric fibers and the outer fibers in the tapered part, making it possible to support a smaller load than before. Further, if the supporting load is the same as in the conventional case, there is an advantage that the cross-sectional area of the rod can be reduced, the thermal resistance can be increased, and the amount of heat penetration can be reduced. Furthermore, the slope of the above taper is set to 1730
By doing the above, the distance between the fittings fitted to both ends of the rod hardly changes, so when supporting between two points with this insulating support rod, the distance between the fulcrums can be maintained stably. .
