Weld the fixed plates, the base plate 1, and the base ring plate 11 into a whole, and leave corresponding screw holes on each fixed plate. Make the front and rear movable modules according to the required dimensions;

[0040] Step 2: Install screws on the second plate 3, the fifth plate 6, and the seventh plate 7 and secure them in place with nuts. Adjust the position of the upper and lower movable plates 15. Tighten the first screw 18 and the second screw 19 to the desired height, secure the upper and lower movable plates 15 with the screw holes, and tighten the fifteenth nut 37 and the sixteenth nut 38 to secure the screws.

[0041] Step 3: Insert the grooves of the front and rear movable modules 13 into the corresponding second plate 3, and insert the third screw 20 and the fourth screw 21 into the two holes of the seventh plate 8. Twist a nut into the third screw 20 and the fourth screw 21 on the inner side of the mold respectively. After using the screws to advance the front and rear movable modules 13 to the desired position, twist a nut into the third screw 20 and the fourth screw 21 on the outer side of the mold respectively (forming a nut combination), and tighten all the nuts to the seventh plate 8 to fix the third screw 20 and the fourth screw 21 in position;

[0042] Step 4: Twist a nut into each of the second screw rod 17 and the fifth screw rod 22. Then, align the groove of the left movable module 14 with the fourth plate 5, and the two holes with the second screw rod 17 and the fifth screw rod 22. After pushing the left movable module 14 to the desired position, twist a nut into each of the second screw rod 17 and the fifth screw rod 22. Tighten the nuts on the screw rods toward the left movable module 14 to fix the position of the left movable module 14.

[0043] Step 5: Twist a nut into the first screw rod 16 and the fifth screw rod 22 respectively, then adjust the groove of the right movable module 12 to the third plate 4, and the two holes to the first screw rod 16 and the fifth screw rod 22. After pushing the right movable module 12 to the desired position, twist a nut into the first screw rod 16 and the fifth screw rod 22 respectively. Tighten the nuts on the screw rods toward the right movable module 12 to fix the position of the right movable module 12.

[0044] Step 6: Pour concrete into the multifunctional concrete mold. After the concrete solidifies and takes shape, remove the mold in the reverse order of the installation of the concrete mold with adjustable specimen size used for irradiation test, and then you can take out the formed concrete specimen.
