Abstract

PURPOSE:To shorten the testing time with a simplified panel support by sliding a slide body to the specified position of a horizontal rail of a shear tester to grasp the upper end of a panel with a support finger while the lower end thereof is fixed with a fixture. CONSTITUTION:A slide body 3 is mounted slidably on the top surface of a horizontal rail 2 arranged at the upper part of a shear tester A through a bearing 11. The slide body 3 is fixed at the specified position on the rail 2 with a clamp bar 15 and then, a knob 20 is turned to grasp and fix the upper end of a panel 4 between a pair of support fingers 5 with a grasping roller 21. The lower end of the panel 4 is fixed through a fixture 7. Thereafter, the clamping of a top plate 13 on the horizontal rail 2 may be relaxed with a clamp bar 15 to make the slide body 3 free to slide. Under such a condition, external force can be applied in the direction of the arrow to permit accurate measurement of a shear stress with limited variations in the measured value.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a panel support device for a shear testing machine. It had been cleaved for a long time. This tendency is particularly noticeable with large panels, and the measured values also vary widely and become inaccurate.

[Purpose of the invention]

The purpose of the present invention is to provide a shear tester that not only can easily support panels and shorten testing time, but also can perform tests under constant conditions, with less variation in measured values, and that can perform accurate tests. The object of the present invention is to provide a panel support device for the following.

[Disclosure of the invention]

The panel support device of the shear testing machine of the present invention +1) id, the panel (

〔Effect of the invention〕

In the present invention, the support is Suri! 11 A pair of support claws that can be moved close to and apart from each other are provided at the bottom of the body, so slide the sliding body to a predetermined position K on the horizontal rail of the shear testing machine and clamp the upper end of the sheath panel between the support claws. By fixing the entire lower end with fixing devices, you can not only easily support the panel and shorten test time, but also be able to always perform tests under constant conditions, reducing variations in measured values. It allows for accurate testing.
