[0002] The cement mortar fluidity tester is suitable for the determination of pozzolanic silicate cement, composite silicate cement, ordinary silicate cement mixed with pozzolanic mixed materials, and slag silicate cement. It is fixed on the base with expansion bolts. The base of the instrument is cast by concrete (or brick-concrete foundation). The bottom size is about 400mm×400mm and the height is about 690mm. It is advisable to fill the gasket between the base and the instrument frame. The level of the desktop can be adjusted by adjusting the height of the gasket. After the instrument is installed, its desktop should be horizontal when measured along two diameter directions at right angles to each other. After the jump table is installed, the fluidity standard sample (JBW01-1-1) is used for calibration.

[0003] Since the bottom mold frame and the disc table top are fixed or integrally welded, it is not convenient to store and carry due to the welding or integrally fixed connection. The disc table top may be touched or damaged during carrying, thus affecting the detection effect. Utility Model Content

A through groove 12 is provided on the top of one side of the connecting seat 2 4. The bottom of the inner surface of the through groove 12 is fixedly connected to the cross rail 9, and the cross rail 9 extends to the outside of the connecting seat 2 4.

[0025] Embodiment 2:

[0026] Figure 1-4The utility model shows a combined bottom mold of a cement mortar fluidity tester according to an embodiment of the present invention, comprising a bottom mold frame 1, a disc table top 2 is arranged on the top of the bottom mold frame 1, a connecting seat 1 3 is fixedly connected to the front and rear positions of the bottom of the disc table top 2, a connecting seat 2 4 is fixedly connected to the top of the bottom mold frame 1, guide grooves 5 are provided on the front and rear sides of the surface of the connecting seat 1 3, vertical rails 6 are fixedly connected to the surrounding of the surface of the connecting seat 1 3, vertical grooves 7 for the vertical rails 6 to slide up and down are provided around the inner cavity of the connecting seat 2 4, the top end surface of the vertical groove 7 passes through the top end surface of the connecting seat 2 4, which facilitates the insertion of the connecting seat 1 3 into or out of the connecting seat 2 4, and a support seat 8 is fixedly connected to the top of the inner cavity of the connecting seat 2 4, and the distance between the front and rear end surfaces of the support seat 8 and one side of the inner cavity of the connecting seat 2 4 is five millimeters The width of the support seat 8 is the same as the width of the oblique block 10. The width of the support seat 8 is the same as the width of the oblique block 10 to prevent the connecting seat 3 from touching the oblique block 10 when moving downward or upward, thereby affecting the moving trajectory of the connecting seat 3. The front and rear positions of the top of the support seat 8 are fixedly connected with a cross rail 9, and the surface of the cross rail 9 is slidably connected with the oblique block 10. A gap is formed between the two connecting seats 3, and the gap formed is greater than the front and rear width distance of the oblique block 10.
