Abstract

PROBLEM TO BE SOLVED: To provide a brace such that the generation of frictional sound can be prevented and that a gap between its shaft and its stiffening pipe can be adjusted properly. SOLUTION: A brace 10a comprises a stiffening pipe 11 made of a rectangular steel pipe and a shaft 12 made of flat steel, which is passed through the stiffening pipe 11 and supported on one of the opposite inner corner parts of the stiffening pipe 11 with a gap θ between them. A liner 13 comprising two steel plates 13a, 13b with a lubricant 14 between them is inserted and supported in a gap θ between the inner corner part of the stiffening pipe 11 and each side end of the shaft 12 by a fixing means 15 using spot welding, so that the liner 13 covers each side end of the shaft 2. When the shaft 12 is exerted with an axial compressive force and restricted by the stiffening pipe 11, the corners of the shaft 12 at ends on both sides do not make direct contact with the interior walls of the corner parts of the stiffening pipe 11, while the sides of the two steel plates 13a, 13b constituting the liner 13, where the lubricant intervenes, are allowed to preferentially slide on each other without resistance, preventing the generation of frictional sound.

However, FIGS. 15 and 16 in Japanese Patent Application Laid-Open No. 9-221830 mentioned above.

In the operation of assembling the brace material, the values of the gaps α and β between the side end of the shaft member 2 and the stiffening tube 1 greatly affect the stiffening effect. 2 is determined, and 1/20 to 1/4 of the thickness of the flat steel as the shaft 2
The gaps α and β are such that the stiffening tube 1 is slidable between the side ends of the flat steel and the stiffening tube 1 so that the stiffening tube 1 is not restrained during assembly.
However, in practice, there are dimensional tolerances in the stiffening tube 1 and the shaft member 2, and it is difficult to form such a desired gap at all times in assembly work. , Β tend to be greater than the required value. Further, it is time-consuming and complicated to adjust the gap α and the gap β to the same degree.

However, if the gap α and the gap β are larger than required values, the stiffening effect of buckling is small when an axial compressive force acts on the shaft member 2, and the original function can be sufficiently performed. When the gap α and the gap β are different in size, for example, on the side of the small gap α, the corner inner wall in the stiffening pipe 1 and the corner of the side end of the shaft member 2 easily come into contact with each other, Friction noise is easily generated.

On the other hand, the technique shown in FIG. 17 according to the above-mentioned Japanese Patent Application Laid-Open No. 9-221871 can easily adjust the gap between the outer member 4 and the shaft member 2, but has the following problems.

When an axial compressive force is applied to the shaft member 2 by using the brace material as described above, only the inner wall of the corner portion in the outer member 4 and the corner of the side end portion of the shaft member 2 come into contact with each other. , Fricatives are likely to occur. In this case, even if one or both of the outer peripheral portion of the shaft member 2 and the inner peripheral portion of the outer member 4 are coated with a Teflon-based or urethane-based surface treatment material having a low friction coefficient, the corners in the stiffening tube 1 are not affected. If only the corner between the inner wall and the side end of the shaft member 2 is in contact, the effect of the coating is small, and a similar friction noise is generated.

2 is restrained by the stiffening tube 11, the reinforcing plate 16
Is not in direct contact with the corner inner wall of the stiffening tube 11, and instead, the outer surface of the steel plate 23 a constituting the liner 23 is coated with the lubricating material 14. The inner wall of the corner in the rigid pipe 11 slides preferentially without resistance to prevent the generation of friction noise, and at the same time, the surface of the steel plate 23a coated with the lubricant 14 is also in contact with the side end of the shaft 12. Sliding without resistance due to surface contact makes it possible to double prevent the generation of friction noise. FIG. 12 is a side view showing one embodiment of the liner fixing means used in the present invention, and FIG.
It is a front view which has a partial cross section by CC line 2 of FIG.

The lid 24 of the fixing means, which is a feature of the present invention, is attached to the end of the stiffening tube 11 by welding. Reference numeral 26 indicates the welded portion. The lid 24 is a two-part lid member 24.
a, 24b, and cutouts 25a, 25b are provided so that the shaft member 12 and the reinforcing plate 16 can pass through.
Even if the brace material 10 is attached to a structure or the like and an axial compressive force acts on the shaft material 12, the single-side lubricating liners 20 and 21 are stopped by the lid 24 and do not go out of the stiffening tube 11. . Therefore, not only can they fully demonstrate their functions, but also the lid itself can prevent the influence of outside air,
The deterioration of the lubricant can be prevented.

According to the present invention as described in the above embodiment, when an axial compression force acts on a shaft and the shaft is restrained by a stiffening tube, both ends of the shaft are Since the corners and the inner walls of the corners in the stiffening tube are prevented from directly contacting each other, there is no friction between the both ends of the shaft due to the corners. Instead,
Since the lubricated surface of the lubricating interposed composite liner, or the one-side lubricating liner or the two-side lubricating liner, slides preferentially without resistance, no friction noise is generated.
In the case of a brace material having a reinforcing plate, no friction noise is generated.
