[Formwork design output processing by formwork design system X]
Next, with reference to FIGS. 3 to 5, details of the formwork design output process for realizing the formwork design method by the formwork design system X according to the embodiment of the present invention and designing and outputting the formwork will be described.
In the formwork design output process of the present embodiment, the design data 200 conforming to the standard of a concrete concrete product is acquired and processed by the user using the application GUI, and then output data for the 3D printer 3. Convert to 210. At the time of this conversion, the data is converted into output data 210 having a shape optimized for the production of a concrete molded product form, and divided if necessary. The output data 210 that is output is three-dimensionally modeled by the 3D printer 3.
Further, the formwork design output process of the present embodiment can be realized mainly by the control unit 10 and the image processing unit 11 of the formwork design apparatus 1 executing the control program stored in the storage unit 12. .
Hereinafter, with reference to the flowchart of FIG. 3, details of the formwork design output processing of the present embodiment will be described for each step.

(Step S101)
First, the design data acquisition unit 100 performs design data acquisition processing.
When the user starts an application of the formwork designing apparatus 1 and designates reading of the design data 200 by the input unit 13, the design data acquisition unit 100 acquires the design data 200. At this time, the design data acquisition unit 100 reads design data 200 such as a file at a location designated by the user and stores it in the storage unit 12.
Further, the design data acquisition unit 100 may convert the file format of the design data 200 into a format suitable for the form design of a concrete molded product. Specifically, for example, the design data acquisition unit 100 may specify each component from CAD data or the like and classify it into a tree format, and convert the polygon of each component into data in a unique format. At this time, the design data acquisition unit 100 may appropriately complement the incomplete data portion where the direction of the normal line is reversed between the surfaces or there is a gap. .

(Step S102)
Next, the design data processing unit 110 performs design data processing.
For example, the design data processing unit 110 performs 3D rendering of the read design data 200 by the image processing unit 11 and causes the display unit 14 to display the design data 200, and causes the user to instruct the part to be processed by the input unit 13 through the GUI.
Referring to the example of FIG. 4, when the user instructs the part to be processed and the method of processing using the input unit 13, the design data processing unit 110 acquires this. The design data processing unit 110 performs processing for adding a three-dimensional model corresponding to the instructed method by dividing the polygon of the design data 200 at the instructed location or adding a polygon. Specifically, the design data processing unit 110, for example, draws and adds a character or pattern designated by the user as a polygon group by designating the size, depth, shape, or the like.

FIG. 4A shows an example in which the user designates one surface of the concrete molded product of the design data 200.
FIG. 4B shows an example in which a user designates a character and a pattern “ABC city ★” and processes and reflects the design data 200. In this case, the design data processing unit 110 processes the design data 200 so as to be a reverse letter because it is data of the formwork.

  In addition to the example of FIG. 4, the user can specify an arbitrary character or pattern and specify the size, shape, or the like. That is, in the case of a character, it is possible to specify font, size, depth and height of a solid, deformation of a shape, a curved surface, and the like. In the case of a pattern, 3D data, pixel data, or the like can be designated. Based on these instructions, the design data processing unit 110 converts the data into appropriate polygon data and adds it to the design data 200.

(Step S103)
Next, the output data conversion unit 120 performs output data conversion processing.
For example, when the user gives an instruction “convert to output data” at the input unit 13 using the GUI of the application, the output data conversion unit 120 acquires this instruction. Then, the output data conversion unit 120 converts the design data 200 into, for example, output data 210 for the 3D printer 3.

At this time, the output data conversion unit 120 may divide the output data 210 into specific units for each mold to be assembled when molding a concrete molded product.
Further, the output data conversion unit 120 may perform strength calculation and structure calculation of the design data 200. Accordingly, the output data conversion unit 120 may divide the output data 210 by a specific unit adjusted so as to maintain a strength that does not lose its shape when molding the concrete. Further, for example, the output data conversion unit 120 may divide the output data 210 in a specific unit that has a strength that is difficult to be damaged or deformed. At this time, the output data conversion unit 120 may convert the output data 210 according to the difference in strength when the assumed strength is different between the original design time and the output time. Specifically, when the design data 200 is design data of a conventional steel formwork, but the raw material for modeling of the 3D printer 3 is resin or the like, the output data conversion unit 120 adjusts to this. May be converted to increase the strength. At this time, for example, the output data conversion unit 120 may increase the thickness of a polygon at a portion where the stress of the output data 210 is large, or increase the intensity by combining the division units. Further, the division unit of the output data 210 may be changed or the assumed strength or the like may be changed according to the concrete molding method designated by the user.

Further, the output data conversion unit 120 may convert the output data 210 after, for example, performing a process of filling a gap in the design data 200 and reducing the joint portion of the surface. At this time, for example, when the polygon of the design data 200 is converted into STL data, the output data conversion unit 120 doubles or thickens the polygon on the concrete molding surface in particular so as to be solid and difficult to form a gap. Also good. In addition, when creating slice data, the output data conversion unit 120 adds a command that causes the 3D printer 3 to be shaped so that the direction in which the material is output is orthogonal to each surface or to close the gap. Or may be slightly shifted for each surface. Thereby, it becomes possible to prevent the leak at the time of shaping | molding of a concrete molded product.
On the contrary, the output data conversion unit 120 creates a structure like a beam in the interior of the polygon of the design data 200, and the output formwork is hard to be deformed and the strength is increased. The output data 210 may be converted.

Further, the output data conversion unit 120 may smoothly convert the unevenness of the surface on which the concrete molded product is molded, for example.
Specifically, when the angle between the polygons on the surface on which the concrete is molded is not gentler than the specific angle, the polygons in the design data 200 may be divided and made gentle. Further, when there is an acute angle between the surfaces of the polygons of characters and patterns, the polygons may be divided and smoothed. Thereby, it becomes easy to peel the concrete molded product after molding.
Note that the output data conversion unit 120 may convert the design data 200 into the output data 210 after making the above changes, or once convert the design data 200 into the output data 210 and then perform the above conversion. Good.

  FIGS. 5A to 5E show an example in which the output data 210 of a mold divided in units that can be manufactured by the 3D printer 3 and a part thereof are drawn.

(Step S104)
Next, the output unit 130 performs output processing.
The output unit 130 outputs the output data 210 converted by the output data conversion unit 120 to the 3D printer. In the present embodiment, the output unit 130 transmits the output data 210 to the 3D printer 3.
When the 3D printer 3 acquires the output data 210, the 3D printer 3 models in 3D based on the raw material. Thereby, it becomes possible to manufacture the formwork of a concrete molded product using the output data 210 created by the formwork design apparatus 1.

In addition, you may use the formwork of the concrete molded product main force by 3D printer 3 for the shaping | molding of the concrete demonstrated below as it is.
Also, the divided formwork can be filled with an adhesive or putty such as epoxy resin or UV curable resin and bonded, or the surface of the formwork can be polished and smoothed before being used for molding concrete. Good.
Moreover, when the raw material for modeling of the 3D printer 3 is a soft material such as gypsum, the strength may be increased by adding a resin or the like separately.

[Manufacture of concrete molded products]
Here, the example which manufactures a concrete molded product with the formwork designed and manufactured by the formwork design system X which concerns on embodiment of this invention is demonstrated.
The formwork of the concrete molded product of the present embodiment is preferably molded using high-fluidity concrete when it is molded using a resin as a raw material as in the FDM system or the optical modeling system.
Specifically, by using various admixtures such as blast furnace slag, fly ash, silica fine powder, and chemical admixture, etc., high fluidity concrete that is excellent in fluidity, does not separate, and has excellent filling properties even without vibrations is used. And mold. At this time, the molding may be performed with no vibration or slight vibration for removing only bubbles on the surface. That is, by using such high fluidity concrete, it is possible to manufacture a solid concrete product without much vibration even if it is a resin mold with low rigidity.
In addition, by manufacturing a mold with less rigidity with a 3D printer, it is possible to manufacture a concrete secondary product that is inexpensive and excellent in shortening delivery time, and particularly excellent in appearance properties.

By configuring as described above, the following effects can be obtained.
Conventional concrete molded products are made of concrete with a slump of about 3 to 8 cm, and are molded with strong vibrations using a table vibrator or form vibrator to produce a solid and excellent appearance product. Was. However, for that purpose, the formwork has to have a firm (strong) structure, and it has been necessary to manufacture a strong one by welding, bolting or the like using a steel material or a steel plate.
For this reason, the method described in Patent Document 1 cannot be used for the formwork of such a concrete molded product.
On the other hand, the formwork design apparatus 1 of the formwork design system X according to the embodiment of the present invention includes a design data acquisition unit 100 that acquires the design data 200 of the formwork of a concrete molded product, and a design data acquisition unit. Design data processing unit 110 that processes design data 200 acquired in accordance with a user instruction, and design data 200 processed by design data processing unit 110 for a 3D printer suitable for a concrete molded product Output data converter 120 for converting the output data 210 into the output data 210.
By comprising in this way, it becomes possible to provide the formwork design apparatus 1 which can be used for the formwork of a concrete molded product.

In addition, conventional steel molds are troublesome for welding and are deformed by welding heat, and thus require a lot of time for manufacturing. For example, a delivery time of at least three weeks or more is required.
On the other hand, if the output data 210 is created by the formwork designing apparatus 1 of the present embodiment, and the formwork is manufactured by modeling with the 3D printer 3, the formwork can be molded within several hours to several days. Thereby, the delivery date of manufacture of concrete molded products, such as precast concrete, can be shortened, and the plan of a manufacturing process becomes easy.

Conventionally, the mold cost occupying the manufacturing cost is high, and the orderer of the concrete molded product bears the mold cost.
On the other hand, it becomes possible to manufacture a formwork with a normal 3D printer by designing with the formwork design apparatus 1 of this embodiment. Thereby, a cheaper formwork than the conventional steel formwork can be manufactured. As a result, it is possible to reduce the formwork cost in the manufacturing cost of the concrete molded product and to suppress the product sales price, so that a sales promotion effect is obtained and the profit is increased.
Moreover, the design freedom of the design etc. of a concrete molded product can be increased by designing with the formwork design apparatus 1 of this embodiment.

Further, the form design apparatus 1 according to the embodiment of the present invention is characterized in that the design data processing unit 110 performs processing for adding a three-dimensional character or pattern to the design data 200.
Constructed in this way, the output data 210 designed by the formwork designing apparatus 1 is shaped by a 3D printer, so that a concrete molded product with letters or patterns added can be easily manufactured according to the user's intention. It becomes possible to do.
In other words, since 3D printers can be produced in small quantities, a variety of shaped concrete molded products can be “customized” according to the intention of the orderer.

Further, in the formwork designing apparatus 1 according to the embodiment of the present invention, the output data conversion unit 120 is a size that can be output by a 3D printer for each formwork assembled at the time of molding a concrete molded product, It is characterized in that the design data 200 is divided into specific units adjusted so as to maintain the strength not to lose shape during molding, and converted into output data 210 for each divided design data 200.
By configuring in this way, it is possible to manufacture a mold having sufficient strength and less deformation even if it is modeled and output by a 3D printer using a resin or the like as a raw material.

Moreover, in the formwork designing apparatus 1 according to the embodiment of the present invention, the output data conversion unit 120 fills the gap in the design data 200 so as to prevent leakage at the time of molding a concrete molded product, and a joint portion of the surface It is characterized by decreasing.
By configuring in this way, it is possible to manufacture a formwork optimum for a formwork of a concrete molded product that needs to be filled with concrete even if it is modeled by a 3D printer. Moreover, since the gap of the manufactured formwork is reduced, it is possible to reduce leakage even in the case of high fluidity concrete.

In addition, since steel used in conventional molds has good adhesion to concrete, a mold release agent for demolding was required when producing a concrete molded product.
On the other hand, the formwork designing apparatus 1 according to the embodiment of the present invention is characterized in that the output data conversion unit 120 smoothly converts the unevenness of the surface on which the concrete molded product of the output data 210 is molded. To do.
By comprising in this way, it becomes possible to suppress use of a peeling agent. In particular, when a resin is used as the raw material for modeling the 3D printer 3, the mold release from the concrete is good, and a release agent such as mold oil is unnecessary. Thereby, one process of manufacture of a concrete molded product can be omitted, and it can contribute to efficiency improvement and cost reduction.
In the case where a resin is used as a raw material for modeling in the 3D printer 3, if the unevenness of the output data 210 is originally smooth at a specific ratio, it is not necessary to use a release agent.

In addition, the formwork designing apparatus 1 according to the embodiment of the present invention further includes an output unit 130 that outputs the output data 210 converted by the output data conversion unit 120 to a 3D printer.
With this configuration, it is possible to create output data 210 optimized for the 3D printer 3, and it is possible to manufacture a more precise, high-speed, and low-cost formwork.

Further, when a conventional steel formwork is stored for a long period of time, corrosion (rust) occurs during storage management, and it is necessary to perform a pretreatment such as polishing when reused.
On the other hand, the formwork produced by modeling the output data 210 designed by the formwork designing apparatus 1 according to the embodiment of the present invention with a 3D printer such as the 3D printer 3 is created each time by the 3D printer. Therefore, it is possible to save labor.
Moreover, when the raw material of modeling of 3D printer is resin etc., rust does not generate | occur | produce and the effect that it is excellent in storage management is also acquired. Moreover, in this case, since it can be manufactured lighter than a conventional steel mold, handling of the manufactured mold becomes easy.

  Note that the configuration and operation of the above-described embodiment are examples, and it is needless to say that the configuration and operation can be appropriately changed and executed without departing from the gist of the present invention.

  The formwork designing apparatus of the present invention can be used industrially because it can design a formwork of a concrete molded product that can be output by a 3D printer.
