Description

Filling mold model of special-shaped structure and its production method

The present invention relates to special-shaped structures and molding models thereof, in particular to a molding model of a special-shaped structure and a manufacturing method thereof, as well as special-shaped structures and a manufacturing method thereof.

In the traditional construction engineering method, for reinforced concrete structures, regardless of the scale of construction, after completing the steel tying operation of the structural skeleton of the columns and beams, floors or walls, etc., each structure is then According to the size and shape required by the design, formwork is used to construct corresponding pouring mold models around each structural frame, and then concrete is poured into the pouring mold model. When the solidification strength of the concrete reaches the standard value of concrete cube compressive strength, the formwork can be removed.

In the early days, the formwork only had wooden formwork, which could be reused according to usage habits, but the number of reuses was not many. After the project was completed, many wooden formwork became waste. Furthermore, the wooden formwork was easy to absorb water, degumming, bulging, shelling, cracking, and had to be reassembled. At that time, the board seams were difficult to deal with, and the thickness of the wooden formwork varied, leading to problems such as structural cross-sectional size deviations. Therefore, steel formwork, plastic formwork or aluminum alloy formwork...etc. have been developed.

For example: China's new patent No. 207620358, the abstract mentions a composite high-strength plastic formwork. The formwork includes an upper side plate, a middle plate and a lower side plate that are arranged parallel to each other. A plurality of first support members extending in one direction. On a cross-section perpendicular to the first direction, the plurality of first support members are connected to each other in a "W" shape; a A plurality of second support members extending along the second direction are connected to each other in a "W" shape in a cross-section perpendicular to the second direction. Or, China's new patent No. CN204850422U (new model name: ribbed plastic formwork) mentions that the front of the formwork body is flat, and the back of the formwork body is provided with vertically crossed reinforcing ribs around and in the middle. Or, Chinese Invention Patent Publication No. CN107217842A (invention title: a curved beam plate side formwork construction template and its installation method) mentions that the present invention relates to a curved beam plate side formwork construction template and its installation method, using a plastic formwork The flexibility ensures that the bendable plastic formwork can be freely adjusted in any arc. By setting up ridges, it ensures that the formwork will not deform in the vertical direction.

However, whether it is wooden formwork, steel formwork, plastic formwork or aluminum alloy formwork, the construction method is time-consuming and laborious, especially relying on a large number of manual operations. In today's manpower shortage situation, the construction time is often prolonged. Furthermore, using the aforementioned traditional formwork to make a cast-in-place model requires too much manual operation, and the quality of construction workmanship will also affect the construction quality. Therefore, the traditional formwork construction method often causes unstable construction quality.

Based on the above reasons, many researchers or related industries have developed three-dimensional printing templates. For example, the abstract of U.S. Patent No. US11065782 (invention title: Method for casting a construction element) mentions moving the material deposition head and selectively depositing material to create a formwork; pouring building material in contact with at least a portion of the formwork; allowing the building material to at least partially solidify to form a structure; and removing at least a portion of the formwork from the structure. Or there are research papers (paper name: Rapid Composite Formwork: An Automated and Customizable Process for Freeform Concrete Through Computational Design and Robotic Fabrication, authored by Guy E. Gardner and four others, published on July 8, 2020) that mention the use of Three-dimensional printing is used to design structures with special surface textures.

However, there are several problems as follows in the aforementioned patent cases or documents: (1) There is only one-dimensional surface modeling, and free modeling such as two-dimensional and three-dimensional surfaces is not realized. (2) Bending only through the plasticity of plastic has material limitations. (3) There is only a single local technical description using template perfusion, and there is a lack of overall description of demoulding, joints, etc. (4) Stiffening ribs provide uniform reinforcement of the entire formwork without reducing material usage. (5) The focus is on reducing mold consumption and producing special surface textures through composite molds, rather than analyzing and manufacturing three-dimensional sharply curved free-form surface shapes.

Based on the above reasons, it is necessary to improve the design of formwork for reinforced concrete structures to solve the above problems. In addition, if the construction procedures and time can be further reduced, and the problem of form explosion during pouring concrete can be avoided, it will be greatly improved. Solve construction problems of reinforced concrete structures.

Referring to Figure 4, the present invention provides a method for making a casting model of a special-shaped structure, which includes the following steps: (S101) Obtain the watering prototype information matching the special-shaped structure 2; (S102) Perform calculation and analysis on the information of each watering prototype to generate pressure distribution information matching each template body 100; (S103) Use topology optimization technology to generate strengthening information for setting multiple structural reinforcements 102 on the surface or inside of each formwork body 100 based on the pouring prototype information and pressure distribution information. When making each formwork body 100, it can be produced together. The structural reinforcement part 102 is provided, and each structural reinforcement part 102 is used to strengthen the strength of each formwork body 100 to avoid the problem of mold explosion during the process of pouring the filling material into the pouring prototype; (S104) Use topology optimization technology to generate assembly information for setting extension wings 104 on the edges of each formwork body 100 based on the pouring prototype information and pressure distribution information. When making each formwork body 100, the extensions can be produced together. The wing plate 104 is used to fix each template 10 together using the fixing clamp 5; (S105) Use topology optimization technology based on the watering prototype information and pressure distribution information to generate watering information that sets at least one pouring hole 106 in each formwork body 100 at a position staggered from each structural reinforcement part 102. Each pouring hole 106 is staggered from each other. The purpose of the structural reinforcements 102 is to prevent the pouring holes 106 from damaging each structural reinforcement 102 to enhance the strength of the template body 100; (S106) Use topology optimization technology to add the enhanced information, the assembly information and the pouring information to the pouring prototype information to generate a plurality of template finished product information; and (S107) Use an additive manufacturing machine to produce a finished product of the template 10 based on the finished product information of each template.

In the present invention, the pouring prototype information includes information on the size, shape, material and structural strength of the plurality of formwork bodies 100. The pressure distribution information is calculated using engineering auxiliary software during the process of pouring the filling material into the pouring prototype. The amount of pressure applied to each template body 100.

In the present invention, the additive manufacturing machine can be a three-dimensional printer, and the additive manufacturing machine can use plastic materials or metal materials, or even composite materials mixed with plastic materials and metal materials to make each template 10 .

In order to further illustrate the process of making a casting model of a special-shaped structure, an example is given below:

In this embodiment, it is expected that the three-dimensional printer will use poly(ethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate), also known as: Each template is made of Polyethylene Terephthalate Glycol (PETG) material. The yield strength of PETG material is 50 million Pascals (MPa). The safety factor should not exceed one-half of the yield strength, which is 25 million Pascals (MPa). Therefore, use simulation software (for example: Ansys Structures) to obtain pouring prototype information that matches the pouring mold model of the special-shaped structure. The pouring prototype information is each formwork body 100 of the formwork 10 as shown in Figure 1, and does not include the structure. The shape and size of the reinforcing part 102, the extended wing plate 104 and at least one pouring hole 106 are calculated and analyzed using simulation software to calculate and analyze the information of each pouring prototype to generate pressure distribution information that matches each template body. Each pouring prototype information simulates the pressure distribution information of concrete pouring completed in one hour, two hours and four hours.

As shown in Figures 5 and 6, the pressure distribution information generated by the concrete pouring material on the formwork body 100 after being poured within one hour of simulation almost all shows a color level above green on the outside or inside (concrete side) of the formwork body 100 , there are also some yellow and red color scales, and the maximum pressure is 135MPa (the location selected by the dotted circle in Figure 5). In Figures 5 and 6, pressures greater than 25 MPa are all represented by red color scales.

As shown in Figures 7 and 8, the pressure distribution information generated on the formwork body 100 by simulating the concrete pouring completed within two hours almost all shows dark blue and light blue color gradations on the concrete side of the formwork body 100. There are also a small number of green color scales, and the maximum pressure is 71MPa (the location selected by the dotted circle in Figure 7). In Figures 7 and 8, pressures greater than 25 MPa are all represented by red color scales.

As shown in Figures 9 and 10, the pressure distribution information generated by the concrete pouring on the formwork body 100 after simulating four hours of pouring is almost all dark blue on the concrete side of the formwork body 100, and there are a few. is a light blue color scale, and the maximum pressure is 43MPa (the location selected by the dotted circle in Figure 9). Since the maximum pressure area of the template body 100 is extremely small, the red color cannot be displayed at the location selected by the dotted circle in Figure 9. Color levels.

In addition, from the perspective of deformation distribution, please refer to Figure 11. The maximum deformation amount produced by the concrete pouring material on the formwork body 100 within one hour of simulation is 209 millimeters (mm). Referring to Figure 12, the maximum deformation amount produced by the concrete pouring material on the formwork body 100 within two hours of simulation is 118 millimeters (mm). Referring to Figure 13, the maximum deformation amount produced by the concrete pouring material on the formwork body 100 within one hour of simulation is approximately 72 millimeters (mm).

To sum up, the pressure distribution information of the concrete pouring completed in one hour, two hours and four hours exceeded the safety factor of 25 million Pa, and the deformation amount was between 72 and 209 mm. In other words, the formwork The body 100 does not meet safety standards.

Referring to Figures 14 to 16, the topology optimization technology is then used in the simulation software to generate reinforcement information for setting a plurality of structural reinforcements 102 on the surface or inside of each template body 100 based on the watering prototype information and pressure distribution information, and then used separately The simulation software simulates the pressure distribution information generated by concrete pouring completed in one hour, two hours and four hours. In Figures 14 to 16, pressures greater than 25 MPa are represented by red color scales.

Please refer to Figures 17~19. The maximum pressure generated by the concrete pouring completed within one hour is 71 MPA, and the maximum deformation is 94mm; the maximum pressure generated by the concrete pouring completed within two hours is 40MPA, and the maximum deformation is approximately is 54mm; the maximum pressure generated by the concrete pouring completed within four hours is 24 MPA, and the maximum deformation is 33mm.

According to the above, we can observe that the maximum pressure generated by the concrete pouring completed within four hours is less than the safety factor (25MPA), and the maximum deformation is 39mm less, which has reached sufficient reinforced strength, and smaller The deformation amount of each formwork body 100 will not cause the problem of mold explosion during the process of pouring the filling material into the pouring prototype. As for the assembly information and pouring information generated using topology optimization technology, a similar method will be used to verify the strength of each template body 100, so that the additive manufacturing machine can respectively produce the finished template 10 based on the finished template information. Therefore, the mold filling The model is chosen to be filled with concrete within four hours to solve the problem of mold blasting.

Please refer to Figure 20. The present invention is a method for manufacturing a special-shaped structure, which includes the following steps: (S201) Provide a plurality of connectors 40 on the base 4; (S202) Set the structural frame 3 on the base 4, and connect a part of the structural frame 3 to the connecting piece 40; (S203) Connect the above-mentioned templates 10 with the corresponding extension wings 104, and assemble the templates 10 together to form the casting model 1; (S204) Use the fixing clamp 5 to connect the extended wing plate 104 of each finished template 10; (S205) Filling material is poured from each pouring hole 106 into the pouring mold model 1, and whenever the filling material is about to overflow from the pouring hole 106, each pouring hole 106 is plugged with a plug 42 until the pouring mold model 1 is filled. Filler; (S206) After the filling material solidifies to a predetermined solidification level, each formwork 10 is removed, and the special-shaped structure 2 is formed from the base 4, the connector 40, the structural skeleton 3 and the filling material.

In summary, the present invention uses an additive manufacturing mechanism to create free-form molding models 1 such as two-dimensional and three-dimensional curved surfaces, which will allow the present invention to be applied to the design of various special-shaped structures, and the additive manufacturing machine It is not limited to being made of plastic materials, but can also be made of metal materials or composite materials. In addition, the present invention uses software to analyze the pressure distribution of filling materials into the molding model 1, and uses topology technology to provide reinforcing ribs on the surface or inside of the formwork body 100 to avoid the problem of mold explosion and reduce material waste. , Furthermore, the structure of the template 10 of the present invention is specific and clear, easy to disassemble and assemble, and complete instructions for connection and demoulding are provided, which improves the problems of the prior art.
