Abstract
The utility model discloses a tool for skid resistance and compression resistance testing of a right-angle fastener, wherein the tool is applied to a right-angle fastener skid resistance and compression resistance testing apparatus for building detection. The tool comprises a pressure beam and at least two pressure rods. A connecting structure is arranged in the middle of the pressure beam. One ends of the pressure rods are installed at the pressure beam by bolts and the other ends of the pressure rods are provided with arc clamps having semicircular structures; anti-skid structures are formed at the two ends of the inner sides of the semicircular structures and protruding structures are formed at the tops of the inner sides; strain gauge type pressure sensors are embedded at the protruding structures; and the heights of the protruding structures are identical with those of the anti-skid structures. Besides, the distance between the two adjacent pressure rods is 150mm to 200mm. And because of the embedded strain gauge type pressure sensors, the influence on the detection result by the tool itself can be minimized. Compared with the prior art, the tool enables the skid resistance and compression resistance of the right-angle fastener to be detected at universal material testing equipment. Moreover, the size of the tool is small; the detection data are accurate; and the operation is simple.
