[0032] Each support column core group 141 comprises a trapezoidal push seat 1411, a plurality of anti-jamming openings 1412 are formed in the bottom surface of the trapezoidal push seat 1411 in intervals, and a plurality of column cores 1413 and sleeves 1414 are arranged on the top surface of the trapezoidal push seat 1411 in intervals, a sealing ring 1415 for preventing leakage when the column core 1413 is lifted is sleeved on the upper cylinder of the sleeve 1414, and each sleeve 1414 is sequentially sleeved in the column core through hole 115.

[0033] Each of the aforementioned lifting mechanisms 142 includes a bidirectional threaded screw 1421, and the left and right sides of the bidirectional threaded screw 1421 are threadedly connected to two unfolding push seats 1422 for pushing the trapezoidal push seat 1411. A plurality of support crossbars 1423 and a second spring 1424 are horizontally fitted between the two unfolding push seats 1422. The upper end of the inner side of the two unfolding push seats 1422 is provided with an inclined push surface 1425 that abuts against the inclined surface on the trapezoidal push seat 1411. The bidirectional threaded screw 1421 and each support crossbar 1423 are located directly below the anti-jamming opening 1412.

[0034] The first moving slide 151 includes a U-shaped moving slide 1511, and the bottom surface of the U-shaped moving slide 1511 is longitudinally spaced with a plurality of anti-arc grooves 1512 for positioning and fitting the first roller 153, and the top surface of the U-shaped moving slide 1511 is spaced with a plurality of moving cavities 1513. The first moving slide 151 and the second moving slide 152 have the same structure.

[0035] The bottom surface of each of the aforementioned positioning cavities 1513 is formed from right to left as a low surface 15131, a ramp surface 15132, and a high surface 15133. Working principle: The production method is as follows: First, a molding mold platform mechanism 1 is transferred between two slide rails 2. Then, the molding mold platform mechanism 1 is quickly electrically connected. On the external control panel, the first moving slide 151 and the second moving slide 152 on the mold frame drive mechanism 15 are operated to move and push the mold frame lifting assembly 13, so that the square vertical frame 1361 rises to the top surface of the mold platform plate 111 to form the mold groove required for UHPC board casting.

[0036] The movement of the mold frame drive mechanism 15 is achieved by the synchronous lateral extension and retraction of two bidirectional hydraulic cylinders 155, which drive the first moving slide 151 to roll on each of the first rollers 153 and the second moving slide 152 to roll on each of the second rollers 154. The first moving groove 122 and the second moving groove 123 can be lubricated to make the movement of the first moving slide 151 and the second moving slide 152 smoother and more wear-resistant. When the first moving slide 151 and the second moving slide 152 move laterally... During positioning, the positioning wheel 133 moves back and forth between the low surface 15131, the ramp surface 15132 and the high surface 15133 within the positioning cavity 1513, thereby achieving the overall lifting of the mold frame lifting assembly 13. After the mold frame lifting assembly 13 is lifted, the first spring 135 will be in a taut state, so that when the positioning wheel 133 moves to the low surface 15131 again, the first spring 135 can provide a rebound force to drive the mold frame lifting assembly 13 to descend within the mold frame lifting groove 112.

[0037] Then through the external console drive module drive mechanism 15 on each push mechanism 142, the folding synchronization of each support column core group 141 is pushed, and each column core 1413 is lifted to the required mold groove of the UHPC plate pouring forming.

[0038] Then the reinforcement net is hoisted into the mold groove, and each column core 1413 supports the reinforcement net, so that the reinforcement net is suspended in the middle of the mold groove.

[0039] The lifting of the reinforcement support mechanism 14 is driven by the worm gear on the motor 144 to rotate the worm gear 143, and under the action of the linkage rod 145, the bidirectional threaded screw rod 1421 on each push mechanism 142 is synchronously rotated, and the two expansion and folding push seats 1422 on each group of push mechanisms 142 are expanded or folded on the push mechanism slide rail 124 by screw rotation. When the two expansion and folding push seats 1422 are folded, the inclined surfaces 1425 are pushed against the inclined surfaces on the trapezoidal push seat 1411 to lift, thereby realizing the bearing and lifting of the trapezoidal push seat 1411. The support cross bar 1423 is arranged transversely on the two expansion and folding push seats 1422, so that the stress generated when the two expansion and folding push seats 1422 are pushed can be borne on the support cross bar 1423, preventing the bidirectional threaded screw rod 1421 from being affected by stress.

[0040] In addition, when the two expansion and folding push seats 1422 are expanded, the trapezoidal push seat 1411 has enough weight to automatically lower the column core 1413 in the sleeve 1414.

[0041] Then the material distribution machine main body 3 slides against the mold groove to pour UHPC raw materials, and then the lifting vibration table main body 4 slides against the forming mold table mechanism 1 to vibrate and make the UHPC raw materials compact to form support on the bottom surface of the reinforcement net. Then the column cores 1413 need to be lowered to the original position, and then the screed machine main body 5 slides against the surface of the UHPC raw materials in the mold groove to perform screeding and smoothing, and finally the UHPC plate is obtained.

[0042] In addition, the material distribution machine main body 3, the lifting vibration table main body 4, and the screed machine main body 5 are prior art, and the specific implementation of the material distribution, vibration, and forming operations will not be described in detail.

[0043] Finally, the forming mold table mechanism 1 of the poured and formed UHPC plate is transported to the outside for curing, and the forming mold table mechanism 1 is powered on to perform demolding operation on the UHPC plate.

[0044] In addition, the mold frame 136 and each fixed component 137 are fixed by pressing, and when different specifications of mold frames 136 are replaced, screws do not need to be disassembled in sequence, which can realize the purpose of quick replacement and save time and effort.

[0045] In addition, when the UHPC plate in the mold groove is condensed and drained, water flows from the gap between the square frame plate 131 and the mold lifting groove 112, and is discharged outward from each drainage channel 117.

[0046] In addition, when the forming mold table mechanism 1 is demolded in the maintenance area, each column core 1413 is uniformly distributed and synchronously pushed up to the bottom surface of the UHPC plate by the steel bar supporting mechanism 14, and then the mold lifting assembly 13 is lowered by the mold frame driving mechanism 15, so that the UHPC plate is in a suspended state on the top surface of the forming mold table mechanism 1, and thus the external transfer equipment can horizontally fork or lift the UHPC plate for transfer.

[0047] The above shows and describes the basic principles and main features of the present application and the advantages of the present application, and it is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application.
