[First embodiment]
A concrete placement management device 100 as a first embodiment of the present invention will be described with reference to FIGS. 1A to 5. FIG. The concrete placement management device 100 divides a structure into small blocks of a predetermined size according to a concrete placement plan, sets up a concrete placement plan, and manages efficient concrete placement. be.

Normally, when concrete is placed in a structure, unhardened concrete is transported by an agitator vehicle (concrete carrier), and, for example, unhardened concrete is sequentially placed in the formwork assembled in the construction area of 1 day. type in Then, before the previously cast concrete hardens, the next concrete is poured and compacted by a vibrator or the like to integrate the two concretes. By repeating the work from placing to integration, the placing of concrete into the construction area is completed. After the concrete is poured, it is cured for a certain period of time to harden, and the assembled formwork is demolded.

In this case, for example, when concrete is poured sequentially into a structure as shown in FIG. must be integrated by In addition, the time for pouring refers to the time from the end of pouring of the previous concrete to the start of pouring of the next concrete. The start of the pouring time is set at the time when the pouring of the previous unhardened concrete ends, and even if compaction by a vibrator or the like continues, the measurement of the pouring time is started. This is because the concrete has already started to harden when the unhardened concrete has been poured. At this time, if the time for pouring concrete exceeds the control time (for example, the control time according to the Standard Specifications for Concrete), a cold joint or the like may occur in the jointed portion of the concrete, which may result in a weakened portion. Therefore, in placing concrete for structures, it is important to manage the time from mixing of materials, the order of pouring concrete, and the time for pouring concrete.

Here, when the scale of the concrete construction area increases, a large amount of concrete is required, and the number of agitator vehicles required to transport the concrete increases. Furthermore, in order to place concrete in a large-scale structure, it is necessary to divide the structure into multiple layers according to the transportable capacity of the agitator vehicle, etc., and place the concrete in order. number of layers tends to increase. As a result, the number of joints increases, so in order to prevent weak parts such as cold joints 150 from occurring, it is necessary to consider the time and amount of concrete to be poured, and the speed, sequence and thickness of the concrete to be poured. It was necessary to make a concrete casting plan 160 by deciding such things as.

However, the work of dividing the structure into several layers or dividing it into small blocks of a predetermined size in order to set up the concrete pouring plan 160 can be performed on site using the two-dimensional blueprint of the structure. was done manually by field workers. For this reason, it is often difficult to make a stamping plan for dividing layers and dividing into small blocks and in what order to stamp them, which has been a burden on the field workers. Therefore, by using the concrete placement management device 100, the user can easily set the layer division, the division into small blocks, and the order of placing each small block based on the basic conditions such as the supply amount of concrete and the casting speed. become.

Next, referring to FIGS. 1B to 1E, management of a concrete placement plan using the concrete placement management apparatus 100 will be described. First, as shown in FIG. 1B, three-dimensional design information 120 including three-dimensional data of a structure designed using a three-dimensional CAD (Computer-Aided Design) or the like is connected to the concrete placement management apparatus 100. The image is displayed on a monitor or display, or the display 140 of a portable terminal such as a tablet or smartphone owned by the user. The three-dimensional design information 120 also includes information such as construction areas and construction periods, for example. The three-dimensional design information 120 is created in advance using three-dimensional CAD or the like.

The three-dimensional design information 120 is a construction area set according to the amount of concrete that can be placed in a predetermined period, and is divided into a plurality of large blocks 123, 124, 125, and 126. FIG. The construction area is set, for example, as a range of concrete that can be placed in one day. For example, consider a case where attention is focused on a large block 123 and this large block 123 is divided into small blocks of a predetermined size.

First, as shown in FIG. 1B, the user designates a division reference point 121 that serves as a reference for division into small blocks in a large block 123 to be divided into small blocks (large block of interest). Then, the concrete placement management apparatus 100 sets the division reference point 121 at the position designated by the user. Here, the division reference point 121 is a reference point for determining in which direction the large block 123 is divided based on which position.

In the example shown in FIG. 1B, the division reference point 121 is set at the vertex portion (bottom left bottom) of the large block 123 . Note that the division reference point 121 can also be set at points other than the vertex portions. It can be set to any internal position. The user can set division reference points for the other large blocks 124 , 125 , and 126 by performing the same operation as for the large block 123 .

Next, as shown in FIG. 1C, the axis is set. That is, considering the division reference point 121 as the origin, the concrete placement management apparatus 100 sets the end point 122 in the X-axis direction at the position specified by the user. Then, the concrete placement management apparatus 100 generates an X-axis 127 as a line segment passing through the end point 122 from the dividing reference point 121 . The generated axis (X-axis 127) may be displayed, for example, near the large block 123 as illustrated, or may be displayed at a position away from the three-dimensional design information 120. FIG.

Similarly, for the Y-axis and Z-axis, based on the positions of the end points of each axis designated by the user, the concrete placement management apparatus 100 divides the division reference point 121 into line segments passing through the designated end points. , the Y-axis and Z-axis are generated. Each generated axis (Y-axis, Z-axis) may be displayed near the large block 123 or may be displayed at a position away from the three-dimensional design information 120 . Each axis (X-axis 127 , Y-axis, Z-axis) is a line segment parallel to the vertical, horizontal and height directions of the large block 123 .

Subsequently, as shown in FIG. 1D, the user sets parameters necessary for dividing the three-dimensional design information 120 into small blocks of a predetermined size. Parameters set by the user include, for example, equal width division (division interval), equal division (division number and rounding width), and layer thickness. These parameters are set by, for example, inputting numerical values into predetermined boxes of a parameter setting window displayed on the right side of the display 140 .

Here, equal width division refers to the case where a structure is divided at a predetermined width (predetermined division interval) to obtain small blocks of a predetermined size. In this case, for example, division lines of the structure are generated and displayed at intervals of 800 mm from the division reference point 121 (see FIG. 1D).

Equal division refers to the case where a structure is divided so that a predetermined division number of small blocks is generated. The rounding width determines, for example, the size unit of each small block generated by division when equally dividing. For example, if the rounding width is set to 100 mm, small blocks of sizes such as 600 mm, 700 mm, and 800 mm are created in units of 100 mm increments (the unit of the length of one side). will be generated. Similarly, if the rounding width is set to 10 mm, for example, the unit of the size of the block to be generated (the unit of the length of one side) will be 810 mm, 820 mm, 830 mm, etc., in units of 10 mm increments. Blocks will be created.

By setting the rounding width and adjusting the fraction of the size of the small blocks in this way, it becomes easy to manage the volume of each small block, so that the placement of concrete can be easily managed. Then, the concrete placement management device 100 divides the three-dimensional design information 120 into small blocks of a predetermined size according to the set parameters. After dividing into small blocks of a predetermined size, setting the order of concrete placement for each of the small blocks enables appropriate management of concrete placement. The order of implantation is set for each layer, for example, but is not limited to this.

As shown in FIG. 1E, when the structure as a whole includes structures having a plurality of different shapes, for example, by setting division reference points for each structure, the structure As a whole, divide into small blocks. In addition, when one structure is considered to be a structure having a complicated shape, it can be considered that a plurality of structures having different shapes are connected to each other.

When the structure as a whole includes structures having a plurality of different shapes, the connecting portions of the respective structures are located at positions where the cross-sectional changes are discontinuous when the entire structure is viewed from the Z-axis direction. It has a cross section change surface.

When such a cross-section change surface exists, for example, when dividing a structure based on one dividing reference point 131, concrete is continuously poured in a portion straddling the cross-section change surface. The cross-section changing surface becomes a weak point. Therefore, it is necessary to set a boundary on this cross-sectional change surface and manage it. Therefore, it is necessary to set the dividing reference point 131 each time a cross-section changing surface appears. For example, when concrete is poured across a cross-section change surface, moisture rise (bleeding) from uncured concrete occurs, and bleeding concentrates on the cross-section change surface, which may result in a weakened portion. Therefore, when a cross-section changing surface exists, it is preferable to set the dividing reference point 131 so that the cross-section changing surface becomes the boundary surface. In this way, by setting the division reference point 131 on the cross-section changing surface (by using the cross-section changing surface as the boundary surface), it is possible to suppress the generation of small blocks that straddle the cross-section changing surface.

As described above, the user sets a plurality of division reference points 131 for the three-dimensional design information 130, and sets parameters such as division width and division number for each of the set division reference points 131. FIG. Then, the concrete placement management apparatus 100 divides the structure into small blocks of a predetermined size based on the set division reference point 131 and parameters.

Next, with reference to FIG. 2, the configuration of the concrete placement management device 100 will be described. The concrete placement management device 100 has an acquisition unit 201 , a division reference point setting unit 202 , an axis line generation unit 203 and a small block generation unit 204 .

The acquisition unit 201 acquires the three-dimensional design information 120 (130) of the structure. Three-dimensional design information is three-dimensional data of a structure (concrete structure) generated using three-dimensional CAD, and is information including design information such as work zones and processes. May contain information. In addition, the structure may be divided into predetermined blocks according to the process, work area, and member name (part name of the structure), and the three-dimensional design information 120 includes data regarding these predetermined blocks. good too.

Here, the process is, for example, a period set according to the amount of concrete that can be placed in one day, for example, set for the entire structure or for the name of the member. Also, the work section is a section divided as a construction unit, for example, a section divided for each member constituting the structure with respect to the entire structure.

The three-dimensional design information may be generated in the concrete placement management apparatus 100 or may be generated in an apparatus other than the concrete placement management apparatus 100. FIG.

The dividing reference point setting unit 202 selects a target block from among a plurality of large block data indicating a construction area that is included in the acquired three-dimensional design information 120 and that is set based on the amount of concrete that can be placed in a predetermined period. In the first large block data of interest (for example, data for each of the large blocks 123, 124, 125, and 126), a first division reference point that serves as a reference for dividing the first large block data of interest into small blocks of a predetermined size. set.

Here, for example, the division reference point 121 is a reference point for dividing the large block 123 (data of the large block 123) to generate a plurality of small blocks.

The dividing reference point can also be set at an arbitrary position. That is, the division reference point is not only a point (position) on the three-dimensional design information 120 of the structure, but also a point (position) away from a point on the three-dimensional design information 120 of the structure, for example, It is also possible to set it at an arbitrary point (position).

Also, it is possible to set a plurality of division reference points. For example, if the shape of the structure is complex, or if the structure as a whole is a combination of multiple structures, it is possible to set multiple division reference points according to the shape of the structure. It is possible.

Furthermore, if the three-dimensional design information 120 of the structure includes a cross-section change plane, the division reference point is set on the cross-section change plane. Here, the cross-sectional change plane is, for example, a plane including a position where the cross-sectional change of the structure is discontinuous when the structure is viewed from the vertical direction. That is, the cross-section changing plane generally refers to a horizontal plane in which the horizontal cross-sectional shape of the structure changes, but the way of taking the cross-section is not limited to the plane horizontal to the vertical direction of the structure. A cross-sectional change plane includes a change in cross-sectional shape of a plane perpendicular to an arbitrary axial direction of the structure. Therefore, by setting the dividing reference point on the cross-section changing surface, it is possible to control to prevent the formation of small blocks straddling the cross-section changing surface. For example, if the structure as a whole includes a plurality of structures, the joints between the structures will be cross-section changing surfaces. Reference numeral 202 sets a division reference point on the cross-section changing plane.

Further, the cross-section changing surface is set in advance by, for example, a CAD operator or the like at the stage of designing a structure using three-dimensional CAD. For this reason, for example, when a person in charge of a construction site sees the three-dimensional design information of a structure at a concrete casting site, the three-dimensional design information including the three-dimensional data of the structure should display the cross-section changing surface. is possible. Therefore, even when the division reference point 121 is set on the cross-section change plane, the division reference point 121 can be set with reference to the cross-section change plane displayed in the three-dimensional design information 120 . In addition, the division reference point setting unit 202 can also display the cross-section changing surface.

Axis line generator 203 generates a first axis line (X axis 127) and a second axis line (Y axis) extending in any two directions from the first division reference point (division reference point 121), and a first axis line (Y axis) from the first division reference point. and a third axis (Z-axis) extending in a direction perpendicular to a plane containing the axis and the second axis.

The axis becomes a line segment that serves as a reference when dividing the large block 123 or the like. For example, when dividing the large block 123, etc., the large block 123 is divided by dividing lines perpendicular to the axes (X-axis 127, Y-axis, Z-axis). be the standard for the case. Note that the dividing line does not have to be orthogonal to each axis.

As described above, even if the user specifies the direction in which the X-axis and the Y-axis extend, or the concrete placement management apparatus 100 automatically determines the direction in which the X-axis and the Y-axis extend, good. Moreover, the directions in which the X-axis and the Y-axis extend may be any directions. Furthermore, each axis generated here can be shared by each of the other large blocks 124, 125, 126, or each of the other large blocks 124, 125, 126 can generate its own axis. good. In addition, since each axis line is a line segment used as a reference when dividing each of the large blocks 123, 124, 125, 126, along the vertical, horizontal and height directions of the large blocks 123, 124, 125, 126 and the structure. It doesn't have to be anything.

Further, for example, the axis line generation unit 203 generates the first axis line and the second axis line so that the plane containing the first axis line and the second axis line is a horizontal plane, and furthermore, the axis line generation unit 203 generates the first axis line and the second axis line so that the plane containing the first axis line and the second axis line is a vertical plane. Generate 3 axes. In this way, when the plane containing the first axis (X-axis 127) and the second axis (Y-axis) is the horizontal plane and the third axis is the vertical line, the actual construction of the structure This is advantageous because it enables management of concrete placement in a state.

Further, the axis line generator 203 generates the first axis line and the second axis line so that the first axis line (X axis 127) and the second axis line (Y axis) are orthogonal to each other. When the cross-sectional shape of the structure is, for example, rectangular, circular, semicircular, rhomboid, etc., when the axis is generated so that the first axis and the second axis are orthogonal, in the subsequent division into small blocks, It becomes possible to generate small blocks that facilitate casting management.

The small block generation unit 204 sets each of the first axis (X-axis 127), the second axis (Y-axis), and the third axis (Z-axis) with the first division reference point (division reference point 121) as the origin. A plurality of small blocks are generated by dividing the first target large block data at intervals or a predetermined number of divisions. When dividing into blocks, it is also possible to divide the blocks into arbitrary widths.

The small blocks to be generated are, for example, separated from the large block 123 (first large block of interest) by a predetermined interval ( For example, intervals of several hundred mm) or divided by the number of divisions.

Note that the division of the large block 123 may be a combination of division by a predetermined interval and division by a predetermined number of divisions. That is, for example, the large block 123 may be divided at predetermined intervals (several hundred mm intervals) in the X-axis direction and the Y-axis direction, and at a predetermined number of divisions in the Z-axis direction. By setting the placing order for the plurality of small blocks generated in this way, it is possible to appropriately manage the placement of concrete. The placement order is set for each layer, for example, but is not limited to this. The order of placement is also set according to the arrangement and number of adjacent small blocks.

Furthermore, division into small blocks can be performed by setting the width of the generated small blocks to an arbitrary size. That is, by finely adjusting the size of the small blocks generated by the above-described procedure, the generated small blocks can have a more balanced configuration. Also, by individually setting the size of each generated small block, the large blocks 123, 124, 125, 126, etc. can be divided into a plurality of small blocks.

For example, it is possible to divide a large block once at predetermined intervals to generate small blocks, set the width of the generated small blocks to an arbitrary size, and perform fine adjustment individually. For example, the size of the small block can be adjusted by changing the values shown in the width column of the table shown on the right side of FIG. 1D.

For example, the width of the row with 4 in the "number" column (the fourth small block) is currently 700 mm, but is increased by 50 mm to 750 mm. Make it absorb with a block. For example, it is possible to adjust the size of the small block so that the width of the row (the third small block) in which the "number" column is 3 is currently 800 mm, but is reduced by 50 mm to 750 mm. . Thus, the size of the small block can be adjusted by changing the numerical value of the width of the generated small block.

Also, in the table shown on the right side of FIG. 1D, the size of the small block can be adjusted by adding rows or deleting predetermined rows. For example, if a large block is divided into a predetermined number of divisions, and the width (size) of the generated small block becomes larger than expected, one row is added, that is, the small block is increased by one. , the width of the generated small blocks can be adjusted. Conversely, for example, when a large block is divided by a predetermined number of divisions, but the width of the generated small block is smaller than expected, one line is deleted, that is, the small block is divided into 1 You can also adjust the width of the generated sub-blocks by decreasing by one.

Furthermore, as described above, in addition to the method of dividing a large block at a predetermined interval or a predetermined number of divisions, before generating small blocks, the size of each small block to be generated is individually specified, and the specified size is specified. It is also possible to generate each of the small blocks with As a result, when a small block is generated, it is possible to divide the large block while checking the relationship with the previously generated small blocks and the overall balance.

Also, when dividing the large block 123 into a predetermined number of divisions, for example, fractions may occur due to the relationship between the length of one side of the large block 123 and the number of divisions. In this case, the fraction can be adjusted by setting the rounding width. For example, if the rounding width is set to 100 mm, each small block generated by dividing by a predetermined number of divisions has a side length of 100 mm unit (eg, 800 mm, 700 mm, etc.). Also, for example, if the rounding width is set to 10 mm, each generated small block will have a side length of 10 mm units (for example, 750 mm, 760 mm, etc.).

For example, if the length of the large block 123 in the X-axis direction is 4,700 mm, the number of divisions is 6, and the rounding width is 100 mm, five small blocks with sides of 800 mm are generated, and 5 small blocks with sides of 700 mm are generated. One small block with edges is generated (see FIG. 1D, etc.). By setting the rounding width in this way, it is possible to suppress the generation of small blocks having extremely different sizes, which facilitates the placement management of concrete. The position of the block for setting the rounding width can be specified at the center or end of the target axis (X-axis, Y-axis, Z-axis). Here, the center of the symmetrical axis is, for example, the row of number 4 (4th row cell) in the table (where the X axis is displayed) shown on the right side of FIG. set, making this row a fractional size row. Further, the ends of the symmetrical axis are the rows of numbers 1 and 6 (the first cell and the sixth cell) in the table shown on the right side of FIG. 1D, and the rounding width is set for these rows. and these rows become fraction-sized rows.

Note that when a large block is divided by a predetermined number of divisions (equal division), small blocks of fractional size are generated in the center row of the target axis, and when a large block is divided by a predetermined interval (equal width division), the target Fractional size blocks can be generated at the ends of the axis. It should be noted that the position where the small block of the fractional size is generated is not limited to the position shown here.

In addition, when the large block 123 is divided at a predetermined interval (for example, 700 mm interval), if a small block with a size equal to or smaller than the predetermined interval (700 mm or less) is generated (if a fraction occurs), a small block equal to or smaller than the predetermined interval is generated. Blocks may be left at their original size. For example, if the size of the small blocks below the predetermined interval is about 600 mm, the small blocks may be left as they are.

However, for example, if the size of the small blocks with a predetermined interval or less is 50 mm, the small blocks with this predetermined interval or less may be incorporated into another small block or distributed to a plurality of other small blocks. For example, if there are five other small blocks, the blocks may be divided into the other small blocks by 10 mm. In this case, the sizes of the other small blocks are 10 mm larger than the predetermined interval initially specified by the user.

Each of the generated small blocks becomes a unit for managing the time of concrete placement start and concrete placement end time, etc., and a unit for calculating the pouring time between adjacent small blocks. It also becomes.

The size of the small block is determined according to, for example, the amount of concrete that can be placed in a predetermined period (for example, one day) and the amount of concrete that can be transported by one agitator vehicle. The methods are not limited to these. In addition, if it is desired to control the time for placing concrete in more detail, it is possible to set the size of the small block to a smaller value. Conversely, if only rough control over the concrete pouring time is required, it is possible to set the size of the small block to a larger value. The size of the small block can be changed by adjusting the division interval and the number of divisions, for example.

Next, an example of the placement amount table 301 of the concrete placement management apparatus 100 will be described with reference to FIG.

[Second embodiment]
Next, a concrete placement management device 700 according to a second embodiment of the present invention will be described with reference to FIGS. 6 to 8. FIG. FIG. 6 is a diagram for explaining the configuration of a concrete placement management device 700 according to this embodiment. A concrete placement management device 700 according to the present embodiment differs from that of the first embodiment in that it has a moving part. Since other configurations and operations are the same as those of the first embodiment, the same configurations and operations are denoted by the same reference numerals, and detailed description thereof will be omitted.

For example, consider a waterway 601 as shown in FIG. 6 as a structure. The channel 601 has a concave shape with a depressed center, and this shape continues for a considerable length. As the three-dimensional design information of the waterway 601, the waterway 601 is divided into several large blocks 611, 612, 613 as shown. Each of the large blocks 611, 612, 613 is designed according to, for example, the amount of concrete that can be placed in one day.

First, the first large block 611 is set as the first target large block, and the dividing reference point 621 is set at the illustrated position. Using the set division reference point 621 as a reference, the large block 611 (first large block of interest) is divided at a predetermined interval or a predetermined number of divisions to generate a plurality of small blocks (see dotted lines in FIG. 6).

Here, the waterway 601 is a long recessed structure, and can also be regarded as a structure in which a predetermined number of large blocks (611, 612, 613) are connected in succession by dividing the waterway 601 by construction section or construction period. . As described above, in the waterway 601 as a structure, since a plurality of large blocks of the same shape appear, the same operations and settings (setting of predetermined intervals, predetermined number of divisions, etc.) must be performed. becomes complicated.

When dividing the large block 612 into a plurality of small blocks as the second large block of interest (second large block of interest), the predetermined intervals and the predetermined number of divisions are set again as in the case of the large block 611. Is required.

Therefore, in the large block 612, for operations other than the setting of the dividing reference point 622, the operations and settings performed in the large block 611 are transferred to the large block 612 as they are so that similar operations can be performed. By moving the settings of the large block 611, the large block 612 can be divided into small blocks in the same way as the large block 611 (see the dotted line in FIG. 6).

Also, in the large block 613, similarly to the large block 612, the division reference point 623 is set, and for other operations, etc., the operations and settings made in the large block 611 are transferred to the large block 613 as they are. move. Similarly to the large block 611, the large block 613 can also be divided into small blocks in the large block 613 (see the dotted line in FIG. 6). By performing similar operations on subsequent large blocks, the large block can be divided to generate a plurality of small blocks.

In this way, in a structure where large blocks of the same shape or similar shape appear multiple times, once the division reference point is set, other settings and operations will be performed by moving the previous large block ( By copying), in this embodiment, simplification of the operation is attempted.

Next, the configuration of the concrete placement management device 700 will be described with reference to FIG. Concrete placement management device 700 further includes moving unit 701 . First, the division reference point setting unit 202 divides the second large block data of interest (for example, the data of the large block 124), which is different from the first large block data of interest (the data of the large block 123), into the large block data of a predetermined size. A second division reference point is set as a reference for division into small blocks. In this case, it is assumed that the large blocks 123 and 124 have the same three-dimensional shape and volume. Also, in this case, it is assumed that the small block is generated only in the large block 123 .

The moving unit 701 moves the data of the plurality of small blocks generated for the first division reference point (division reference point 121) and the first large block data of interest to the set second division reference point. The division reference point (division reference point 121) is moved so as to overlap the second division reference point.

Then, the small block generation unit 204 generates a second block based on the moved first division reference point (division reference point 121) and a plurality of small block data generated for the first target large block data. A plurality of small blocks are generated for the large block data of interest (data of the large block 124). For example, the small block generation unit 204 copies the small block data generated for the large block 123 as it is, and generates a plurality of small blocks for the large block 124 .

In this way, by copying the data of a small block that has been generated once, it is possible to easily generate small blocks for large blocks that have the same three-dimensional shape or similar three-dimensional shapes simply by setting the division reference points. becomes. Therefore, small blocks can be easily generated in a structure in which the same three-dimensional shape is repeated multiple times.

Next, the processing procedure of the concrete placement management device 700 will be described with reference to the flowchart shown in FIG. This flow chart is executed by the CPU 410 in FIG. 4 using the RAM 440, and implements each functional configuration of the concrete placement management apparatus 700 in FIG.

In step S801, the concrete placement management apparatus 700 sets a second division reference point that serves as a reference for dividing the second large block data of interest, which is different from the first large block data of interest, into small blocks of a predetermined size. In step S803, the concrete placement management apparatus 700 divides the plurality of small blocks generated for the first division reference point and the first target large block data with respect to the second division reference point set in step S801. Data is moved so that the first division reference point overlaps the second division reference point. That is, the data of a plurality of small blocks generated for the first large block data of interest are copied to the second large block of interest. In step S805, the concrete placement management apparatus 700 divides the plurality of small blocks generated for the first division reference point (division reference point 121) and the first target large block data moved in step S803. Based on the data, a plurality of small blocks are generated for the second large block data of interest.

According to this embodiment, since it is not necessary to set the predetermined interval or the predetermined number of divisions again, small blocks of a predetermined size can be generated more easily, and efficient and easy concrete placement management can be performed. be able to.
