Abstract
Description
[Technical Field]
[0001] The present invention relates to a concrete pouring planning method and a concrete pouring planning support device. [Background technology]
[0002] In concrete work in construction, preventing initial defects is a social requirement to ensure long-term durability, and among other things, preventing cold joints caused by concrete pouring is a fundamental issue in construction management, and construction requires pouring plans to pour concrete within the allowed time, and pouring management that strictly adheres to these plans. However, currently pouring plans are created based on the experience of on-site personnel, and are sometimes created without objective confirmation that they are optimal or not. Even in the planning of pouring block division, which is part of the pouring plan, the person in charge creates a block division plan from a structural drawing, so not only do different people create a variety of plans, but a pouring block division plan created by an inexperienced person may result in a plan that is difficult to actually pour.
[0003] Here, Patent Document 1 proposes a pouring plan creation method and a pouring plan creation device that enable creation of an ideal concrete pouring plan. The pouring plan in the pouring plan creation method is a pouring order in units of construction blocks that sets the order in which concrete is poured into the construction blocks that the construction object is divided into, and includes a block group setting step that sets candidate block groups, which are groups of construction blocks to be poured consecutively, in order for the construction object, and an intra-group order determination step that determines the pouring order within the candidate block group. The block group setting step and the intra-group order determination step are repeatedly executed to determine the pouring order of the construction blocks that make up the construction object. The candidate block group is composed of overlapping blocks adjacent to a target block that serves as the basis for the candidate block group, and extended blocks located around the overlapping blocks.In the block group setting step, when the order of placement within the previous candidate block group is determined, a placed construction block that has not yet been placed into an adjacent construction block and has the earliest placement completion time is selected from among the placed construction blocks, and the selected construction block is set as the new target block to set a new candidate block group.

[0004] [Patent Document 1] Japanese Patent Publication No. 2021-188419 Summary of the Invention [Problem to be solved by the invention]
[0005] According to the method for creating a pouring plan described in Patent Document 1, construction blocks that are not directly related to the pouring of the target block are also included in the group of candidate blocks so that the pouring constraints for the poured blocks can be met earlier, which is effective in shortening the maximum pouring time compared to when only the poured blocks for the target block are considered as candidate blocks. However, the above-mentioned problem of the division of construction blocks being based on the experience of the person in charge has not yet been resolved, and the actual flow behavior of concrete when poured is not reflected in the block division, so there is room for improvement in terms of modeling block division.
[0006] The present invention aims to provide a concrete pouring planning method and pouring planning support device that allows anyone to divide pouring blocks with high accuracy, simulating the flow behavior of actual concrete, regardless of whether they have experience in pouring planning. [Means for solving the problem]
[0007] In order to achieve the above object, one aspect of the concrete pouring planning method according to the present invention is to A concrete pouring planning method for planning concrete pouring blocks during the construction of a concrete structure, comprising: A process A is carried out to create a block image in which a plurality of pouring unit blocks are drawn adjacent to each other, and at this time, the pouring unit block is a polygon close to a circle whose area is determined by the set concrete flow distance; The method is characterized by having a step B in which a structure image, which is a planar image of the concrete structure, is overlaid on the block image to create an overlaid image, and in the overlaid image, the area and centroid of the overlapping area of the pouring unit block and the concrete structure are identified, the area is used as the basis for calculating the concrete volume of the overlapping area, and the centroid is used as the position of the nozzle of the hose when pouring concrete in the overlapping area.
[0008] According to this aspect, in a concrete pouring block division plan, pouring block division is carried out based on an overlaid image in which a block image, which is a polygon close to a circle and whose area is determined by the set concrete flow distance, is drawn with multiple pouring unit blocks adjacent to each other, and a structure image, which is a planar image of the concrete structure, is overlaid, thereby making it possible to formulate a pouring plan based on pouring block division that reflects the actual flow behavior of concrete. Furthermore, by identifying the area and centroid of the overlapping area of the planar image of the pouring unit block and the concrete structure, the concrete volume in the overlapping area can be accurately identified based on the identified area and the planned pouring height of the concrete, and the position of the hose nozzle when pouring the concrete can be accurately set based on the identified centroid position. In addition, in this type of pouring planning method, pouring unit blocks are uniquely created by setting the flow distance of the concrete, a block image comprising multiple pouring unit blocks is created, and an overlaid image is created by superimposing the block image and the structure image, making it possible to perform similar pouring block division regardless of the experience of the person planning the pouring plan. Furthermore, even if the planar shape of the concrete structure is complex, the actual pouring block is defined by the overlapping area of multiple polygons close to circles and the concrete structure, making it easy to plan the pouring plan.
[0009] Here, "a polygon close to a circle" means a polygon with pentagons or more sides that is closer to a circle than a square (quadrilateral), for example, as described in Patent Document 1, and can also be called a "polygon approximating a circle." If circular pouring unit blocks are used to simulate the actual flow of concrete, the end areas of adjacent pouring unit blocks will overlap, making calculations complicated, such as finding the area by deleting the overlapping area from the area of one of the blocks.
[0010] In another aspect of the concrete pouring planning method according to the present invention, The polygon is a regular hexagon, and the block image is formed by arranging a plurality of the regular hexagons without any gaps.
[0011] According to this aspect, since the polygon is a regular hexagon, it is possible to form a polygonal pouring unit block that is as close to a circle as possible, and it is desirable that multiple polygons can be arranged without gaps. In other words, although polygons that can be arranged without gaps include equilateral triangles, squares, and regular hexagons, only regular hexagons are suitable as polygons that are close to a circle.
[0012] Another aspect of the concrete pouring planning method according to the present invention is The flow distance is set depending on the type of concrete.
[0013] According to this aspect, by setting the flow distance according to the type of concrete, it is possible to achieve pouring block division based on highly accurate pouring unit blocks that reflect the flow distance of the type of concrete actually applied. Here, the types of concrete include ordinary concrete and high-flow concrete.
[0014] Another aspect of the concrete pouring planning method according to the present invention is In step B, a threshold value is set for the area of the overlapping area, and overlapping areas with an area smaller than the threshold value are included in the same pouring block as other adjacent overlapping areas.
[0015] According to this aspect, a small overlapping area is extracted based on a threshold value related to the area of the overlapping area, and by including this small overlapping area in an adjacent pouring block rather than as a separate pouring block, it is possible to realize a concrete pouring plan that faithfully simulates actual concrete pouring.
[0016] Further, one aspect of the concrete pouring planning support device according to the present invention is A concrete pouring planning support device that supports concrete pouring block splitting planning during the construction of a concrete structure, The apparatus includes a drawing unit, a specifying unit, a display unit, and a storage unit, The storage unit stores concrete flow distance data, The drawing unit A block image is created in which a plurality of pouring unit blocks are drawn adjacent to each other, and at this time, the pouring unit block is a polygon close to a circle whose area is defined based on the flow distance data, a structure image, which is a planar image of the concrete structure, is superimposed on the block image to create a superimposed image; The identification unit identifies an area and a centroid of an overlapping area of the pouring unit block and the concrete structure in the overlapping image, and uses the area as a basis for calculating the concrete volume of the overlapping area, and uses the centroid as a nozzle position of the hose when pouring concrete in the overlapping area, The display unit displays the block image, the structure image, and the superimposed image, and displays the area and centroid of each of the superimposed regions in the superimposed image.
[0017] According to this aspect, a concrete pouring block splitting plan can be formulated based on a pouring block splitting plan that reflects the actual flow pattern of concrete by superimposing a block image, in which a plurality of pouring unit blocks, each of which is a polygonal block close to a circle and whose area is determined by a set concrete flow distance, on a structure image, which is a planar image of the concrete structure. Then, by determining the area and centroid of the overlapping region of the pouring unit block and the planar image of the concrete structure, the concrete volume in the overlapping region can be accurately determined based on the determined area and the planned concrete pour height, and the position of the hose nozzle during concrete pouring can be accurately set based on the determined centroid position.
[0018] In another aspect of the concrete pouring planning support device according to the present invention, The drawing unit creates the block image by treating the polygons as regular hexagons and arranging a plurality of the regular hexagons without any gaps between them.
[0019] According to this embodiment, since the polygon is a regular hexagon, it is possible to form a polygonal pouring unit block that is as close to a circle as possible, and it is also desirable because multiple polygons can be arranged without gaps.
[0020] In another aspect of the concrete pouring planning support device according to the present invention, The storage unit stores the flow distance data according to the type of concrete, The drawing unit is characterized in that it creates the block image, which includes a pouring unit block whose area is defined based on the flow distance data corresponding to the selected type of concrete.
[0021] According to this aspect, by setting the flow distance according to the type of concrete, it is possible to achieve pouring block division based on highly accurate pouring unit blocks that reflect the flow distance of the type of concrete actually used.
[0022] In another aspect of the concrete pouring planning support device according to the present invention, the storage unit stores a threshold value related to the area of the overlapping region; The identification unit is characterized in that it includes small overlapping areas whose area is smaller than the threshold value in the same pouring block as other adjacent overlapping areas.
[0023] According to this aspect, a small overlapping area is extracted based on a threshold value related to the area of the overlapping area, and by including this small overlapping area in an adjacent pouring block rather than as a separate pouring block, it is possible to realize a concrete pouring plan that faithfully simulates actual concrete pouring. [Effects of the Invention]
[0024] According to the concrete pouring planning method and pouring planning support device of the present invention, anyone can perform highly accurate pouring block division that simulates the flow behavior of actual concrete, regardless of whether they have experience in pouring planning.

[0026] Hereinafter, a concrete pouring planning method and a concrete pouring planning support device according to an embodiment will be described with reference to the accompanying drawings. Note that in this specification and the drawings, substantially identical components may be designated by the same reference numerals to avoid redundant description.
[0027] [Concrete pouring planning method and pouring planning support device according to the embodiment] An example of a concrete pouring planning method and a pouring planning support device according to an embodiment will be described with reference to Figures 1 to 9. Here, Figure 1 is a diagram showing an example of the hardware configuration of the concrete pouring planning support device according to an embodiment, and Figure 2 is a diagram showing an example of the functional configuration of the concrete pouring planning support device according to an embodiment.
[0028] The pouring plan support device 10 is a device that supports a concrete pouring block division plan when constructing a concrete structure.
[0029] The hitting plan support device 10 is configured by an information processing device (computer) such as a personal computer (PC). The computer that constitutes the hitting plan support device 10 includes a CPU (Central Processing Unit) 11, a main memory device 12, an auxiliary memory device 13, an input / output IF (interface) 14, and a communication IF 15, which are interconnected by a connection bus 16. The main memory device 12 and the auxiliary memory device 13 are computer-readable recording media. Note that the above components may be provided separately, or some of the components may not be provided.
[0030] The CPU 11 is also called an MPU (Microprocessor) or a processor, and may be a single processor or a multiprocessor. The CPU 11 is a central processing unit that controls the entire driving plan support device 10, which is made up of a computer. The CPU 11, for example, deploys a program stored in the auxiliary storage device 13 in an executable form in the working area of the main storage device 12, and controls peripheral devices through the execution of the program, thereby providing functions that meet a predetermined purpose.
[0031] The main memory device 12 stores computer programs executed by the CPU 11, data processed by the CPU 11, etc. The main memory device 12 includes, for example, a flash memory, a RAM (Random Access Memory), and a ROM (Read Only Memory). The auxiliary memory device 13 stores various programs and various data on a readable and writable recording medium, and is also called an external memory device. The auxiliary memory device 13 stores, for example, an OS (Operating System), various programs, various tables, etc. The OS includes, for example, a communication interface program that exchanges data with external devices connected via the communication IF 15.
[0032] When the construction planning support device 10 is a computer owned by a person in charge of construction planning for a certain construction project, external devices include, for example, computers owned by people involved in the construction project, and computers in related departments of the head office or branch offices of a construction company.
[0033] The auxiliary storage device 13 is used, for example, as a storage area that supplements the main storage device 12, and stores computer programs executed by the CPU 11, data processed by the CPU 11, etc. The auxiliary storage device 13 is a silicon disk including nonvolatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD: Hard Disk Drive), a solid state drive, etc. Examples of the auxiliary storage device 13 include drives for removable recording media such as CD drives, DVD drives, and BD drives, and examples of removable recording media include CDs, DVDs, BDs, USB (Universal Serial Bus) memories, and SD (Secure Digital) memory cards.
[0034] The input / output IF 14 is an interface for inputting and outputting data between devices connected to the hitting plan support device 10. Input devices such as a keyboard, a touch panel, a mouse or other pointing device, and a microphone are connected to the input / output IF 14. The hitting plan support device 10 receives operation instructions and the like from an operator who operates the input device via the input / output IF 14.
[0035] The input / output IF 14 is connected to, for example, a display device such as a liquid crystal panel (LCD: Liquid Crystal Display) or an organic electroluminescence (EL: Electroluminescence) panel, a printer, a speaker, or other output devices.
[0036] For example, as described below, the screen displays block images in which multiple pouring unit blocks are drawn adjacent to each other, structure images which are planar images of concrete structures, and superimposed images in which these are superimposed.
[0037] The communication IF 15 is an interface with a cable or network to which the playing plan support device 10 is connected. The communication IF 15 transmits the superimposed image, in which the block image and the structure image are superimposed, created by the playing plan support device 10, as well as information on the area and centroid of each superimposed area included in the superimposed image, to the computers or mobile terminals (smartphones or tablet terminals) of the respective parties, via various networks, such as a public network such as the Internet, a wireless network such as a mobile phone network, a dedicated network such as a VPN (Virtual Private Network), or a LAN (Local Area Network).
[0038] 2, the playing plan support device 10 provides various functions of at least an acquisition unit 102, a drawing unit 104, an identification unit 106, a display unit 108, and a storage unit 110 by executing a program by a CPU 11. Here, at least some of the processing functions may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), or the like, and similarly, at least some of the processing functions may be provided by a dedicated LSI (Large Scale Integration) such as an FPGA (Field-Programmable Gate Array), a numerical calculation processor, an image processing processor, or other digital circuits, or the like.
[0039] The acquisition unit 102 acquires structure image data relating to a structure image, which is a planar image of a concrete structure, that has been created by another computer, and the acquired structure image data is stored in the storage unit 110.
[0040] The drawing unit 104 creates various images and displays them on the display unit 108, and also overlays multiple images to create an overlaid image, which is similarly displayed on the display unit 108. Alternatively, commercially available AutoCAD (Computer Aided Design) software may be installed on the computer, and some or all of the drawing functions of the drawing unit 104 may be executed by starting AutoCAD. For example, structure image data created by another computer using AutoCAD may be imported and displayed on the display unit 108, and block images, etc., described below, may also be created using AutoCAD, and various overlaid images, including structure images, may be created by compositing (overlapping) each image (layer).
[0041] 3 and 4, the images created in the drawing unit 104 and displayed on the display unit 108 will be described below. Here, Fig. 3 and Fig. 4 are diagrams showing an example of a block image and an example of a first superimposed image, respectively, displayed on the display unit.
[0042] 3, the block image 20 is formed by arranging a plurality of pouring unit blocks 21, each having a regular hexagonal shape in plan view, adjacent to one another. The pouring unit block 21 is shown as a regular hexagon (an example of a regular polygon) that approximates a circle indicated by a dashed line based on the actual phenomenon in which, when the nozzle of a hose used for pouring concrete is placed at its centroid g1 and concrete is poured, the concrete spreads out in a circular or nearly circular shape around the nozzle.
[0043] Among the common polygons that are close to (approximate to) a circle, a regular hexagon is suitable as a shape that allows adjacent shapes to be placed side by side without any gaps. For example, other regular polygons that can be placed side by side without any gaps in this way include an equilateral triangle and a square, but neither an equilateral triangle nor a square can be said to be a regular polygon that is close to a circle.
[0044] Furthermore, if a pouring unit block is created by overlapping circles that simulate actual phenomena, as shown by the two dotted lines in Figure 3, then when calculating the concrete volume in the pouring unit block, it is necessary to take the time and effort of deleting the area of the overlapping portion from one of the pouring unit blocks, and this becomes even more noticeable when a large number of pouring unit blocks are adjacent to each other, as in the example shown, which is undesirable.
[0045] In this way, as a way to simulate the actual spreading pattern of concrete when it is poured, while also reducing the effort required to calculate the area of the pouring unit block, we decided to apply a block image 20 formed by arranging pouring unit blocks 21, each of which has a regular hexagonal shape that is close to a circle when viewed from above, side by side, as shown in the example.
[0046] Although not shown, various setting screens are displayed on the display unit 108, and on these setting screens, the maximum horizontal flow distance of the arc (arc shown by the dashed line in FIG. 3) adjacent to the regular hexagon, which corresponds to the concrete flow distance r, the length of one side of the block image 20, the pouring height, etc. Furthermore, other information such as a margin for the concrete flow distance (the overlap width of the two arcs shown in FIG. 3) may also be input.
[0047] The flow distance r of the concrete, which defines the area of the regular hexagonal pouring unit block 21, is set depending on the type of concrete used in construction.
[0048] The lateral pouring distance of concrete is generally stipulated according to the type of concrete, and the Concrete Standard Specifications (Japan Society of Civil Engineers) stipulates that for ordinary concrete, lateral movement is prohibited and instead the pouring interval should be 2m to 4m as a guideline, and for high-flow concrete, the principle is 8m to 15m or less. Therefore, when the person in charge of pouring plan sets the flowing distance r, they must properly evaluate it based on the type of concrete to be applied and the flowing distance stipulated in the compliance guidelines, such as the Concrete Standard Specifications, and set it after.
[0049] The drawing unit 104 identifies the centroid g1 of the regular hexagonal pouring unit block 21 created based on the set flow distance r, and draws it inside the pouring unit block 21. Here, the identification of the centroid g1 may be performed by the identification unit 106.
[0050] As shown in Figure 4, the structure image 30 stored in the memory unit 110 is imported into the drawing unit 104 and overlaid on the created block image 20, thereby creating a first overlaid image 40 (an example of an overlaid image) having multiple overlaid areas 45 in which the pouring unit block 21 and the interior of the structure line 41 are overlaid.
[0051] The structure to be constructed included in the illustrated structure image 30 is a reinforced concrete structure with an extremely complex structure line 41, in which numerous partition walls are provided inside a circular exterior wall in plan view, an internal structure that is not continuous with the exterior wall, and an external structure that is not continuous with the exterior wall, are also provided outside the exterior wall. Therefore, pouring plans for constructing the structure by pouring concrete essentially require a lot of time and effort, and the quality of the pouring plan depends on the experience of the concrete pourer.
[0052] As shown in Figure 4, in the first overlaid image 40, among the pouring unit blocks 21 that form the block image 20, there are pouring unit blocks that are completely contained within the structure line 41, while there are also pouring unit blocks that are not completely contained and only a portion of them are contained within the structure line 41.Although the size of the pouring unit blocks 21 has an impact, in a structure with a complex structure line 41 as in the illustrated example, there may be more pouring unit blocks 21 that are only partially contained within the structure line 41.
[0053] For example, among the overlapping areas 45A to 45F marked with diagonal lines in Figure 4, in overlapping area 45D, the pouring unit block 21 is completely contained within the structure line 41, while in the other overlapping areas, only a portion of the pouring unit block 21 is contained; more specifically, the area contained within the structure line 41 varies in a variety of ways.
[0054] In the identification unit 106, for each overlapping area 45 in the created first overlapping image 40, the centroid g2 of the overlapping area 45 is re-identified from the centroid g1 of the original regular hexagonal pouring unit block 21, and the centroid g2 corresponding to each overlapping area 45 is displayed.
[0055] For example, in the overlapping area 45D where the pouring unit block 21 is completely contained within the structure line 41, the centroid position does not change, so the original centroid g1 is maintained, while the centroid positions of the other overlapping areas change from g1 to g2.
[0056] In this way, the centroid g2 (including g1) of the overlapping area 45 indicating the actual concrete pouring area is set as the nozzle position of the hose of each pouring block.
[0057] The identification unit 106 identifies the area of each overlapping region 45, and calculates the concrete volume of the overlapping region 45 by multiplying the identified area by the pouring height data that has already been input.
[0058] In this way, the identification unit 106 identifies the area of each casting block to be used as the basis for calculating the concrete volume, and identifies the centroid of each casting block to be used as the position of the hose tip when pouring concrete.
[0059] The memory unit 110 also stores a threshold value for the area of the overlapping area 45. The identification unit 106 identifies overlapping areas with a small area that is smaller than the threshold value, and performs a calculation to include the overlapping areas in the same pouring block as other adjacent overlapping areas.
[0060] For example, in Figure 4, overlapping area 45E is an overlapping area of extremely small area and is not suitable for being set as a single pouring block, so for example, overlapping area 45E is included in adjacent overlapping area 45F and these are re-set as a common pouring block.
[0061] In this way, by extracting a small overlapping area 45 based on a threshold value related to the area of the overlapping area 45, and including this small overlapping area 45 in an adjacent pouring block rather than as a separate pouring block, it is possible to realize a concrete pouring plan that faithfully simulates actual concrete pouring.
[0062] The pouring planning support device 10 enables anyone to split pouring blocks with high accuracy, simulating the flow behavior of actual concrete, regardless of whether they have experience in pouring planning.
[0063] The concrete pouring planning method according to the embodiment is as follows.
[0064] First, as shown in Figure 3, a block image 20 is created in which multiple pouring unit blocks 21 are drawn adjacent to each other.In this case, the pouring unit blocks 21 are polygons (in the illustrated example, regular hexagons) close to circles whose area is determined by the set concrete flow distance r.
[0065] The concrete flow distance r is set based on the type of concrete to be (planned to be) applied in construction, such as ordinary concrete or high-flow concrete, and the flow distance corresponding to the type of concrete specified in various guidelines, etc., to be applied when planning construction (this is process A).
[0066] Next, as shown in FIG. 4, a structure image 30, which is a planar image of the concrete structure, is superimposed on the block image 20 to create a superimposed image 40.
[0067] In the overlapping image 40, the area and centroid of the overlapping region 45 of the pouring unit block 21 and the concrete structure are identified, and the area is used as the basis for calculating the concrete volume of the overlapping region 45, and the centroids g1 and g2 are used as the positions of the hose nozzles when pouring concrete in the overlapping region 45. The concrete volume for each pouring unit block is calculated by multiplying the identified area of each overlapping region 45 by the set pouring height.
[0068] In addition, a threshold value is set for the area of the overlapping area, and if the area of the overlapping area is smaller than the threshold value, it is included in the same pouring block as other adjacent overlapping areas (this is process B).
[0069] Next, with reference to FIGS. 5 to 9, a method of dividing each overlapping region 45 (pouring blocks) constituting the first overlapping image 40 shown in FIG. 4 into a plurality of cells and sequentially searching each cell will be described.
[0070] Here, Fig. 5 is a flowchart of an example of a cell search method, Fig. 6 is an enlarged view of an example of a second superimposed image, and Fig. 7 is a diagram showing an example of a cell search image displayed on a display unit. Also, Fig. 8A is a schematic diagram explaining an example of a search starting from the nozzle position, and Fig. 8B is a schematic diagram explaining an example of a re-search after moving to an adjacent cell. Furthermore, Fig. 9 is a diagram showing an example of a search calculation result image displayed on a display unit.
[0071] First, a second superimposed image is created as shown in Fig. 5. As shown in Fig. 6, the second superimposed image 60 is formed by superimposing a cell image 50, which is made up of a plurality of vertical and horizontal grids and in which small square cells 51 are arranged side by side in a plan view, a block image 20, and a structure image 30. Here, Fig. 6 shows an enlarged portion of the second superimposed image 60, which has a size similar to that of Fig. 4 as a whole screen.
[0072] In FIG. 6, the area below the structure line 41 is the inside of the structure and corresponds to an overlapping area 45, and the area above the structure line 41 is the outside of the structure and corresponds to a non-overlapping area 48 (step S10).
[0073] After creating and displaying the second overlaid image 60 shown in Fig. 6 in the computer, a third overlaid image, which is an image for cell search, is created. As shown in Fig. 7, the third overlaid image 70 is an image formed by deleting the block image 20 from the second overlaid image 60 and consisting only of the cell image 50 and the structure image 30 (this is step S11).
[0074] For example, the cell located at the centroid g2 (g1) of any overlapping area 45 diagonally downward to the left in FIG. 7 is set as the cell for starting the search, and pouring block calculation is started from this cell (step S12).
[0075] The pouring block calculation is performed by sequentially calculating the four cells (cells above, below, left, and right) adjacent to the starting cell (step S13). Specifically, as shown in Figure 8A, when the function that performs the incorporation process into the pouring block for the cell (x, y) at the current nozzle position is F(x, y), F(x, y) is expressed as follows:
[0076] F(x, y) = {If this cell has already been processed, do nothing and return. If it has not been processed, process this cell.} Next, execute F(x, y+1), then execute F(x+1, y), then execute F(x, y-1), and finally execute F(x-1, y). This marks the end of processing for cell (x, y) and return.
[0077] This incorporation process checks the following three items: (1) Is the selected cell unexamined? (Step S14) (2) Is the cell connected to the structure? (Step S15, is it outside the pouring range? Is the structure not connected?) (3) Does it exceed the maximum lateral flow distance from the nozzle? (Step S16)
[0078] If any of the above items is not satisfied, the cell is excluded from the search and the search for the next adjacent cell continues (step S18). That is, as shown in Figure 8B, the current position is moved to the adjacent cell, the concrete is considered to have been poured, and the search continues recursively (step S17).
[0079] Cell (x+1, y) is the starting point. Next, F(x+1, y+1) is executed, then F(x+2, y), then F(x+1, y-1), and finally F(x, y) is executed (since processing has already finished, it returns). This marks the end of processing for cell (x+1, y), and returns. From then on, the process repeats in the same direction, checking the four adjacent cells.
[0080] After the judgment for the four adjacent cells is completed and the judgment for all cells in one overlapping area 45 is completed, the same judgment is repeatedly performed starting from the cell at the centroid g2 (g1) of the adjacent overlapping area 45.
[0081] The above determination is repeated sequentially, and the calculation (cell search) is terminated when there are no undetermined overlapping regions 45. On the other hand, if an undetermined cell remains when the calculation is terminated, the cell is merged into an adjacent overlapping region 45 (step S19).
[0082] When the cell search is completed, the display unit 108 displays a search calculation result image 80, as shown in FIG. 9, which has a plurality of pouring unit blocks 81 each having a centroid g2 (g1) therein, which is the nozzle position.
[0083] By the above cell search, a block number is automatically assigned to each pouring unit block 81 in the search calculation result image 80, and a cell number is automatically assigned to the multiple cells that make up each pouring unit block 81. In this way, the search calculation result image 80 having pouring unit blocks 81 to which cell numbers are automatically assigned in the computer is suitable for application to T-Con.PAS (registered trademark), a concrete pouring support system.
[0084] It should be noted that the present invention is not limited to the configurations shown here, and other embodiments may be possible in which other components are combined with the configurations described in the above embodiments. In this regard, the present invention can be modified within the scope of the present invention, and can be appropriately determined depending on the application form. [Explanation of symbols]
