Description

Technical Field

[0001] This invention relates to a UHPC production method and molding equipment, belonging to the technical field of UHPC molding equipment. Background Technology

[0002] UHPC, or Ultra-High Performance Concrete, is a new type of building material whose strength, toughness, and durability far exceed those of ordinary concrete.

[0003] In the production of UHPC panels, a reinforcing mesh needs to be placed in the mold groove of the mold table. In order to improve the quality of the formed UHPC panels, the reinforcing mesh needs to be located in the middle of the UHPC panels. Therefore, the reinforcing mesh needs to be suspended and raised. This step requires manual operation, which is time-consuming and labor-intensive. In addition, the current mold table is just a simple casting platform and does not have a demolding function. When demolding the UHPC panels, the mold table needs to be transferred to a flipping machine for demolding. However, the flipping of the flipping machine has certain risks and can easily cause the UHPC panels to crack due to impact. It also occupies the molding space, and the cost of adding a flipping machine will increase significantly. In view of the above shortcomings, this invention proposes a UHPC production method and its molding equipment. Summary of the Invention

Multiple support slide rods and first springs are spaced apart at the left and right sides of the bottom surface of the square frame plate for corresponding to the sliding mouth of the support rod. A mold frame is placed vertically on the top surface of the square frame plate, and multiple fixing components for positioning the mold frame are spaced apart on the outside of the mold frame, and each fixing component is located in the groove of the anti-jamming groove.

[0011] A further improvement is that the mold frame includes a square vertical frame, and a reinforcing edge is welded to the outside of the square vertical frame. A fixing groove and a first pressing slope are provided on the outer side of the reinforcing edge at the position aligned with each fixing component.

[0012] Each of the fixing components is composed of an adjusting screw, a rotating seat and a fixing block connected together. The lower right side of the fixing block is provided with a second pressing slope for abutting against the slope of the first pressing slope to press and fix the mold frame.

[0017] A further improvement is that the main body of the fabric spreading machine, the main body of the lifting and vibrating table, the main body of the scraping and troweling machine, the worm gear, and the linkage rod are all existing technologies, and their structures will not be described in detail here.

[0020] A further improvement is that the mold frame has a multi-layer stacking function.

[0021] Furthermore, this invention also provides a production method for the aforementioned UHPC molding equipment: the production process is as follows:

[0022] First, a molding mold platform mechanism is transferred between two slide rails. Then, the molding mold platform mechanism is quickly electrically connected. On the external control panel, the first and second sliding blocks on the mold frame drive mechanism are operated to move and push the mold frame lifting assembly, so that the square vertical frame rises to the top surface of the mold platform plate to form the mold groove required for UHPC board casting.

[0023] Then, the external control console drives the various lifting mechanisms on the mold frame drive mechanism to close and synchronously lift each support column core group, so that each column core rises into the mold groove required for the UHPC board to be cast and formed.

[0024] Then the steel mesh is hoisted into the mold groove, and each column core supports the steel mesh, so that the steel mesh is suspended in the middle of the mold groove.

[0025] Then, the UHPC material is poured into the mold groove by the sliding body of the material placing machine. Then, the lifting and vibrating table slides to vibrate the forming mold mechanism to make the UHPC material dense and support the bottom of the steel mesh. After that, each column core needs to be lowered and returned to its position. Then, the scraper and trowel slides to scrape and trowel the surface of the UHPC material in the mold groove, and finally obtain the UHPC board.

[0026] Finally, the molding platform mechanism that casts the UHPC board is transported to the outside for curing, and in the curing area, the molding platform mechanism is powered on to perform the demolding operation on the UHPC board.

[0027] The beneficial effects of this invention are:

[0028] This invention provides a UHPC production method and molding equipment. The molding mold platform mechanism, consisting of a mold stand, a demolding mechanism, a mold frame lifting assembly, a rebar support mechanism, and a mold frame drive mechanism, is designed in conjunction with two slide rails, a fabric placing machine body, a lifting vibration table body, and a leveling and troweling machine body to form a UHPC molding equipment. This molding mold platform mechanism can be transported and stacked. The rebar support mechanism provides suspended support when the rebar mesh is placed, eliminating the need for manual shimming, saving time and effort. The mold frame drive mechanism assists in driving the horizontal lifting function of the mold frame lifting assembly. After the rebar support mechanism rises again to lift the UHPC board for demolding, the square vertical frame can descend into the cavity of the mold stand, facilitating external hoisting and transport equipment or forklifts for transport operations and preventing the square vertical frame from falling out. The design incorporates mechanical interference prevention and side drainage to prevent water ingress and damage to the steel reinforcement support mechanism and mold frame drive mechanism on the demolding mechanism frame. The square vertical frame on the mold frame lifting assembly uses a downward pressing design with angled surfaces to secure it. When replacing square vertical frames of different sizes, there's no need to disassemble and reassemble the screws sequentially, allowing for quick and easy replacement. This saves time and effort. Furthermore, each molding mold assembly has its own demolding function, allowing the UHPC board to be horizontally lifted and suspended for demolding after molding. This ensures more stable demolding without the need for external flipping machines for auxiliary demolding, simplifying the molding process and eliminating the risk of cracking or breakage due to impact during demolding. It also saves on additional equipment costs and production space. Attached Figure Description

The first moving slide 151 and the second moving slide 152 have the same structure.

[0062] 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.

[0063] Working principle:

[0064] The production method is as follows:

[0065] 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.

[0066] 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.

[0067] Then, the external control console drives the various lifting mechanisms 142 on the mold frame drive mechanism 15 to close and synchronously lift the various support column core groups 141, so that each column core 1413 rises into the mold groove required for the UHPC board to be cast and formed.

[0068] Then the steel mesh is hoisted into the mold groove, and each column core 1413 supports the steel mesh, so that the steel mesh is suspended in the middle of the mold groove.

[0069] The lifting and lowering of the steel bar support mechanism 14 is achieved by the worm gear on the motor 144 driving the worm 143 to rotate. Under the action of the linkage rod 145, the bidirectional threaded screws 1421 on each lifting mechanism 142 can rotate synchronously. The threaded rotation method allows the two unfolding and closing push seats 1422 on each set of lifting mechanisms 142 to unfold or close on the lifting mechanism slide rail 124. When the two unfolding and closing push seats 1422 are closed, they are pushed up by the two inclined push surfaces 1425 against the inclined surface on the trapezoidal push seat 1411, thereby realizing the load-bearing and lifting of the trapezoidal push seat 1411. The support crossbar 1423 is set laterally on the two unfolding and closing push seats 1422 so that the stress generated when the two unfolding and closing push seats 1422 push against each other can be placed on the support crossbar 1423, preventing the bidirectional threaded screws 1421 from being affected by stress.

[0070] In addition, when the two unfolding pushers 1422 are unfolded, the trapezoidal pusher 1411 itself has enough weight to drive the core 1413 to automatically descend inside the sleeve 1414.

[0071] Then, the UHPC material is poured into the mold groove by sliding the main body 3 of the material placing machine. Then, the main body 4 of the lifting and vibrating table slides to vibrate the forming mold plate mechanism 1 to make the UHPC material dense and support the bottom surface of the steel mesh. Then, each column core 1413 needs to be lowered and returned to its position. Then, the main body 5 of the scraping and polishing machine slides to scrape and polish the surface of the UHPC material in the mold groove, and finally obtains the UHPC board.

[0072] In addition, the main body of the cloth laying machine 3, the main body of the lifting vibration table 4, and the main body of the scraping and troweling machine 5 are all existing technologies, and the specific implementation methods of cloth laying, vibration and troweling are not described in detail here.

[0073] Finally, the molding platform mechanism 1, which has cast and molded the UHPC board, is transferred to the outside for curing. In the curing area, the molding platform mechanism 1 is powered on to operate itself to demold the UHPC board.

[0074] In addition, the mold frame 136 and each fixing component 137 are fixed by pressing. When it is necessary to replace the mold frame 136 of different specifications, there is no need to disassemble and install the screws one by one. This can achieve the purpose of quick replacement and fixation, which saves more time and effort.

[0075] In addition, when the UHPC board in the mold groove condenses and drains, the water flows in from the gap between the square frame plate 131 and the mold frame lifting groove 112, and is discharged outward from each drainage channel 117.

[0076] In addition, when the forming mold platform mechanism 1 is demolded in the curing area, the steel bar support mechanism 14 first pushes the column cores 1413 to be evenly distributed and synchronously pushed on the bottom surface of the UHPC board. Then, the mold frame driving mechanism 15 drives the mold frame lifting assembly 13 to descend, so that the UHPC board is suspended on the top surface of the forming mold platform mechanism 1. Therefore, the external transfer equipment can horizontally lift or suspend the UHPC board for transfer.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
