The permeable pavement brick cleavage tensile strength test universal fixture comprises an upper pressing plate and a lower pressing plate, wherein the lower surface of the upper pressing plate and the upper surface of the lower pressing plate are both arc-shaped surfaces, a guide connecting rod is fixedly arranged on the lower pressing plate, a guide post hole is formed in the upper pressing plate, and the guide connecting rod penetrates through the guide post hole to enable the upper pressing plate to be in sliding connection with the guide connecting rod.

Furthermore, the lower pressing plate comprises a lower pressing plate base at the lower part and a lower pressing plate clamping part at the upper part, and the upper surface of the lower pressing plate clamping part is an arc-shaped surface.

Furthermore, the upper pressure plate comprises an upper pressure plate clamping part at the lower part and an upper pressure plate pressing table at the upper part, the lower surface of the upper pressure plate clamping part is a circular arc surface, and the bottom end of the lower surface is a plane.

Furthermore, the guide connecting rod is a linear optical axis.

Furthermore, a vertical bearing is arranged in the guide pillar hole.

Furthermore, the vertical bearings are multiple and are uniformly distributed in the guide pillar hole in the circumferential direction.

Further, the circular arc radius of the upper surface of the lower pressing plate clamping part is 7.5 cm.

Further, the circular arc radius of the lower surface of the upper pressure plate clamping part is 7.5 cm.

Because the lower surface of top board and the upper surface of holding down plate are circular cambered surface, center when can guaranteeing the concrete sample pressurized is adjusted well to the scale on the accessible direction connecting rod reads length, thereby need not special routing and measure test piece length, its simple structure, low cost, convenient operation, location are accurate, very practical.
