[Modes for carrying out the invention]

[0009] Hereinafter, with reference to the drawings, a temporary scaffolding design program 100 and a temporary scaffolding design system 101 according to embodiments of the present invention will be described.

[0010] The temporary scaffolding design system 101 of this embodiment (hereinafter simply referred to as "design system 101") is a system used for scaffolding planning to design temporary scaffolding to be installed at construction sites, etc. The design system 101 provides a function for designing temporary scaffolding by placing objects representing temporary scaffolding, etc., in a three-dimensional virtual space.

[0011] As shown in Figure 1, the design system 101 includes an input device 15 into which operator inputs operations, a display device 16 for displaying information, and an information processing device 10 (computer) connected to the input device 15 and the display device 16.

[0012] The input device 15 is electrically connected to the information processing device 10 by wire or wireless means and consists of one or more devices operated by an operator. The input device 15 consists of, for example, a touch sensor, a keyboard, a mouse, etc. The input device 15 transmits an input signal to the information processing device 10 in response to the operator's input.

[0013] The display device 16 is a display that is electrically connected to the information processing device 10 by wire or wireless connection. The display device 16 displays information based on signals received from the information processing device 10.

[0014] The information processing device 10 is comprised of a computer equipped with a CPU (Central Processing Unit) for executing programs, a ROM (Read-Only Memory) for storing programs executed by the CPU, a RAM (Random Access Memory) for storing CPU calculation results, a GPU (Graphics Processing Unit), a communication device, and the like. The information processing device 10 is equipped with multiple processors such as CPUs and GPUs. The information processing device 10 performs the various functions of the information processing device 10 described herein by loading programs stored in ROM into RAM and executing them on RAM by the CPU. The information processing device 10 may be comprised of a single computer, or it may be comprised of multiple microcomputers configured to distribute the processing of each control among the multiple computers.

[0015] In this embodiment, the information processing device 10 is a so-called personal computer (PC) and is connected to an external input device 15 and a display device 16. Alternatively, the design system 101 may be provided by a portable terminal such as a smartphone or tablet, in which the input device 15, display device 16, and information processing device 10 are integrated. In this case, the design system 101 may include, for example, a touch panel that functions as both the input device 15 and the display device 16.

[0016] The information processing device 10 includes a storage unit 11 that stores a temporary scaffolding design program 100 (hereinafter simply referred to as "design program 100"), and a processing unit 12 that calls and executes the design program 100 stored in the storage unit 11.

[0017] In addition to the design program 100, the storage unit 11 stores information necessary for processing executed by the design program 100 described in the present specification. For example, the storage unit 11 stores, as information of objects arranged in a three-dimensional space on a design screen W described later, temporary scaffolding objects which are one unit of objects constituting a temporary scaffolding, a site object representing a site where the temporary scaffolding is to be installed, and virtual objects to be virtually installed. Information of each object is information about the shape (dimensions) of the object.

[0018] The storage unit 11 stores information of a plurality of types of temporary scaffolding objects. The information of the temporary scaffolding objects stored in the storage unit 11 includes, for each temporary scaffolding object, shape information as well as information on the type and quantity of members used for the temporary scaffolding object. Details of the temporary scaffolding object will be described later.

[0019] A site object is an object including two-dimensional or three-dimensional information representing the state (spatial shape, arranged equipment, materials, etc.) of a site where a temporary scaffolding is to be installed. The site where the temporary scaffolding is to be installed includes, for example, information of existing or planned buildings. The storage unit 11 stores the site objects in a file format corresponding to each object.

[0020] A two-dimensional site object is, for example, a two-dimensional drawing such as a plan view or an elevation view of a site. Two-dimensional drawings include two-dimensional drawings created by CAD software, images obtained by imaging a site, and images obtained by scanning hand-drawn drawings. A two-dimensional site object is an object having no thickness.

[0021] A three-dimensional site object includes, for example, three-dimensional drawings (3D models) created by CAD software or 3D modeling software (CG software), and three-dimensional data constituted by point clouds or mesh data obtained by reading a site with a 3D scanner.

[0022] In this embodiment, the design program 100 includes a game engine and is provided to the worker as an application for designing temporary scaffolding. Generally, a game engine is software that integrates (packages) the programs necessary to create computer games. The game engine in this embodiment is capable of parallel processing by multiple processors (CPU and GPU) and can perform drawing (rendering) of objects (or models) in three-dimensional space and physics calculations on those objects. The game engine includes, for example, an audio engine, a logic engine, a rule engine, an animation engine, a graphics engine, a user interface engine, a physics engine, etc. The game engine may also include a navigation engine, etc. Furthermore, the design program 100 does not necessarily have to include a game engine.

[0023] Next, we will describe the information processing performed by the design program 100.

[0024] The design program 100 is programmed to receive input signals from the input device 15 and to draw temporary scaffolding objects 20 representing temporary scaffolding in three-dimensional space and display them on the display device 16 according to the received input signals.

[0025] The following describes in detail the functions of the application realized by the information processing performed by the design program 100. In other words, the design program 100 is programmed to enable the design system 101 to realize the following functions.

[0026] [Design screen display and basic functions] When the design program 100 is executed, a design screen W for designing scaffolding is displayed on the display device 16, as shown in Figure 2. The design screen W displays a virtual three-dimensional space on which objects are drawn, a cursor C operated on the design screen W by the operator via the input device 15, and multiple buttons (icons) that can be selected by the operator. The three-dimensional space is a space represented, for example, by mutually orthogonal X, Y, and Z axes. The three-dimensional space includes a reference plane P on which objects are placed. By selecting each button on the design screen W with the cursor C, the corresponding function is executed.

[0027] The design program 100, like 3D CAD software and 3D modeling software, includes basic functions such as saving and loading data files containing the designed data, changing the viewpoint (view) in 3D space, redoing and undoing operations, and moving and rotating objects.

[0028] In this embodiment, the design screen W displays operation buttons B for executing basic functions, a scaffolding creation button B1 for placing temporary scaffolding objects, a lifting equipment button B2 for placing lifting equipment such as stairs, a component list button B3 for displaying a list of the quantities of components used in the designed temporary scaffolding, a model placement button B4 for placing site objects, a size change button B5 for changing the dimensions (size) of the temporary scaffolding, and a dimension display button B6 for displaying the dimensions of the temporary scaffolding objects.

[0029] [Placement of temporary scaffolding objects] Selecting the scaffolding creation button B1 displays the object window W1, which shows candidate temporary scaffolding objects to place. Selecting one of the displayed candidates will display the corresponding 1-unit temporary scaffolding object in 3D space.

[0030] The following explanation will use the example of designing temporary scaffolding by placing a roughly cubic temporary scaffolding object 20, as shown in Figure 3, in three-dimensional space.

[0031] As shown in Figure 3, the temporary scaffolding object 20 includes a work platform 21 that serves as a work area, support columns 22 having plate-shaped flanges 22b (see Figure 4) that can be connected to each other axially and can fix the work platform 21, jacks 23 that are height-adjustable members provided on the ground surface of the support columns 22, and fabric strips 24 and braces 25 provided between adjacent support columns 22. The temporary scaffolding object 20 is composed of a ground surface 27 including the jacks 23, support columns 22, and braces 25, and a frame 28 provided on the upper part of the ground surface 27 including the support columns 22, work platform 21, fabric strips 24, and braces 25. The support columns 22 can be connected to each other axially. The frame 28 is the basic unit of the temporary scaffolding object 20, and multiple frames 28 can be connected and provided on the upper part of the ground surface 27.

[0032] The work platform 21 is roughly rectangular in plan view (XY plan view), and each of its four corners is fixed to one of the four support columns 22. A baseboard is provided on the outer edge of the work platform 21, protruding upwards to prevent workers from falling. Hereinafter, the longitudinal direction of the work platform 21 will be referred to as the "longitudinal direction," the short direction as the "end direction," and the direction perpendicular to the work platform 21 as the "height direction." The height direction is the direction along the Z-axis in three-dimensional space. Multiple support columns 22 are provided at intervals in the longitudinal and end directions. As shown in Figure 4, the storage unit 11 of the information processing device 10 stores multiple types of support columns 22 with different axial dimensions and flange 22b positions, which can be appropriately selected when configuring the temporary scaffolding object 20. "Multiple types of support columns 22" are, for example, support columns 22 of multiple model numbers (standards) from the support column 22 manufacturer, and the support columns 22 shown in Figure 4 are just one example. As shown in Figure 4, the flanges 22b are formed to be larger in diameter than the main body 22a of the support column 22, and multiple flanges are formed spaced apart from each other in the axial direction. A brace 25 is fixed to any flange 22b, or a work platform 21 is fixed via a fabric material 24. When two support columns 22 are connected to each other, the lower end of one support column 22 contacts the upper end of the other support column 22 via a joint member. The jack 23 is provided at the lower end of the support column 22 and its height can be adjusted by extending and retracting so that its length changes continuously.

[0033] The fabric members 24 are provided between adjacent support columns 22 in the longitudinal direction and between adjacent support columns 22 in the gable direction, respectively, to support the support columns 22. The fabric members 24 are provided circumferentially around the ground contact area 27 (near the ground contact surface) to efficiently support the support columns 22, and in Figure 3, they are also provided circumferentially at the upper and lower ends of the frame 28, respectively, and circumferentially between the upper end of the frame 28 and the work platform 21. The braces 25 are fixed to the flanges 22b and are provided intersectingly between the upper end of the frame 28 and the work platform 21. Note that the arrangement of the fabric members 24 and braces 25 shown in Figure 3 is just one example.

[0034] In the design program 100, the support columns 22 can be selected from multiple types of support columns 22 stored in the memory unit 11, and the height of the jacks 23 can be selected within a settable range. The worker can design the temporary scaffolding by connecting any number of temporary scaffolding objects 20 in the longitudinal and end-side directions, and by connecting any number of frame bodies 28 in the height direction.

[0035] In the design program 100, a temporary scaffolding object 20 is selected from the object window W1, and by moving the cursor C on the design screen W to select an arbitrary position, one unit (frame 28) of the temporary scaffolding object 20 is placed at the selected position. The ground contact portion 27 is automatically added to the temporary scaffolding object 20 when attempting to place it on the reference plane P.

[0036] As shown in Figure 2, pressing the resize button B5 displays the settings window W2, which allows you to set the dimensions of one unit of temporary scaffolding object 20. The dimensions set for the temporary scaffolding object 20 include, for example, height, working platform height, longitudinal length, and end-side length. The height and longitudinal length can be set to any value within a predetermined range set for each temporary scaffolding object 20. The working platform height can be set to any value. The end-side length can be set by selecting from several pre-set dimension values.

[0037] The temporary scaffolding object 20 is automatically connected to the already placed temporary scaffolding object 20 by aligning its surface with that of the temporary scaffolding object 20 already placed in three-dimensional space, so that their surfaces are joined together.

[0038] [Extending and retracting of temporary scaffolding] The temporary scaffolding object 20 can be continuously placed or deleted in a predetermined direction by selecting each face of the cube shape and moving it perpendicular to that face. In short, the temporary scaffolding composed of the temporary scaffolding object 20 can be stretched or resized by clicking on each face of the temporary scaffolding object 20 and dragging it perpendicular to it.

[0039] To explain in more detail, as shown in Figure 5(a), for example, one side perpendicular to the longitudinal direction of a temporary scaffolding object 20 is selected, and the temporary scaffolding object 20 is moved away from that side by the length of its longitudinal dimension in the longitudinal direction (in the direction of the arrow in the figure). As a result, as shown in Figure 5(b), a new temporary scaffolding object 20 of the same shape as the original temporary scaffolding object 20 is automatically placed adjacent to it (continuously) in the longitudinal direction. In this way, the temporary scaffolding is extended in the longitudinal direction.

[0040] Conversely, if you select one side of a temporary scaffolding object 20 at one end of a series of temporary scaffolding objects 20 arranged consecutively in the longitudinal direction, and move it longitudinally by a unit dimension toward that temporary scaffolding object 20, the temporary scaffolding object 20 at the end will be automatically deleted. This will shrink the temporary scaffolding in the longitudinal direction. These shrinking and shrinking operations can also be performed in the gable end direction.

[0041] Furthermore, even if you select and drag a face of a temporary scaffolding object 20, if the length dragged in 3D space is less than the dimension of one unit of the temporary scaffolding object 20 (in other words, the longitudinal dimension of the frame 28), a new temporary scaffolding object 20 will not be placed. In other words, in this embodiment, even if you drag a face of a temporary scaffolding object 20, an object smaller than one unit of temporary scaffolding object 20 will not be placed; the system is configured to design temporary scaffolding using combinations of one unit of temporary scaffolding object 20.

[0042] If you need to place a temporary scaffolding object 20 smaller than the one currently being placed, you can select and change it from the scaffolding candidates in the object window W1 (see Figure 2). In this way, by allowing users to freely select the temporary scaffolding object 20 to be placed, and fixing the dimensions of the automatically placed temporary scaffolding object 20 during expansion and contraction to correspond to the selected temporary scaffolding object 20, it is possible to prevent the placement of temporary scaffolding objects 20 with shapes unintended by the worker. Therefore, the design of temporary scaffolding becomes easier.

[0043] Furthermore, although not shown in the diagram, even in the case of a temporary scaffolding object 20 in which multiple frame bodies 28 are stacked in the height direction, by selecting and dragging the side, multiple adjacent temporary scaffolding objects 20 can be automatically placed in a continuous manner in the stretched direction. For example, by dragging the side in the longitudinal direction of three temporary scaffolding objects 20 (frame bodies 28) lined up in the height direction, it is possible to place three new layers of temporary scaffolding objects 20 adjacent to each of the three layers of frame bodies 28 lined up in the height direction. In other words, even if multiple layers of frame bodies 28 are stacked, they can be stretched and compressed as a single unit in a predetermined direction.

[0044] In this way, by selecting and dragging each face of the temporary scaffolding object 20 (in other words, moving the face as if pushing it out), the temporary scaffolding can be intuitively stretched or retracted in any direction.

[0045] [Expansion and contraction of temporary scaffolding in the height direction] When the temporary scaffolding object 20 is dragged in a direction that increases its height, the height of the ground contact points 27 is adjusted first. The ground contact points 27 have stepped upper height limits (thresholds) that allow them to be extended or retracted within a range below the unit height (standard height) of the frame 28. When the temporary scaffolding object 20 is dragged in the height direction and exceeds the threshold, the ground contact points 27 are changed to new ground contact points 27 with a higher height threshold. Repeating this process until the height of the dragged and extended ground contact points 27 reaches the unit height of the frame 28, a new frame 28 is added on top. Accordingly, the ground contact points 27 are changed to those with lower thresholds so that the overall height change is continuous. In this way, the ground contact points 27 are automatically adjusted so that the height can be changed continuously, allowing scaffolding to be designed at any desired height.

[0046] When a temporary scaffolding object 20 is dragged in a direction that decreases its height, it exhibits the opposite behavior to when it is dragged in a direction that increases its height. In this way, the temporary scaffolding object 20 is stretched or compressed in the height direction. This height adjustment is not limited to a single temporary scaffolding object 20; multiple temporary scaffolding objects 20 can be adjusted as a group all at once.

[0047] [Creating a parts list] When the component list button B3 (see Figure 2) is operated, the types and quantities of components used in the temporary scaffolding are calculated based on the temporary scaffolding objects 20 placed in three-dimensional space. Furthermore, the calculated types and quantities of components can be output as an order form in a predetermined format based on a predefined template.

[0048] [Displaying dimensions] When the temporary scaffolding object 20 is placed in 3D space, its dimensions are automatically displayed. The automatic dimension display function can be turned ON / OFF by operating the dimension display button B6 (see Figure 2).

[0049] [Importing and Exporting Objects] When the model placement button B4 (see Figure 2) on the design screen W is selected, a file selection screen (not shown) is displayed, allowing the user to select a file of on-site objects stored in the memory unit 11. By selecting a file, the on-site objects contained in that file are imported into the 3D space. The position of the on-site objects in the 3D space can be changed, similar to the temporary scaffolding objects 20.

[0050] By incorporating the three-dimensional site object 30 into the three-dimensional space, workers can position the temporary scaffolding object 20 while considering its relative position to the site object 30.

[0051] Alternatively, as shown in Figure 6, the temporary scaffolding can be designed by importing the floor plan 31 and elevation 32 of the building on which the temporary scaffolding will be installed as site objects, aligning their positions, and using them as the background. The height of the temporary scaffolding can be adjusted by referring to the ceiling surface of the building in the background, or by creating a temporary ceiling surface at an arbitrary height and referencing it. This simplifies the design work. Note that in Figure 6, the temporary scaffolding object 20 is shown simplified as a cube.

[0052] Furthermore, the designed temporary scaffolding can be exported externally, for example, in 3D data format (such as an obj file), or information about the scaffolding components can be exported externally. This allows the temporary scaffolding designed with the design system 101 of this embodiment to be imported into conventional CAD software or BIM (Building Information Modeling) and used in scaffolding planning.

[0053] [Interference detection function] Design program 100 has an interference detection function that determines interference (contact) between objects by performing physical calculations using the physics engine included in the game engine. Since the method of interference detection can employ known technology, a detailed explanation is omitted.

[0054] The design program 100 performs interference checks on the temporary scaffolding object 20 with the site object 30 whenever a new object is placed or an object is moved in the three-dimensional space (specifically, it checks whether the components of the temporary scaffolding object 20 and the site object 30 overlap). In this embodiment, if the design program 100 determines that the temporary scaffolding object 20 is interfering with the site object 30, it rearranges the temporary scaffolding object 20 so that the two no longer interfere with each other (specifically, so that the components of the temporary scaffolding object 20 and the site object 30 do not overlap) and reconstructs the temporary scaffolding object 20.

[0055] Figure 7 is a schematic diagram showing the procedure for reconstructing the temporary scaffolding object 20 when the lower part of the temporary scaffolding object 20 interferes with the site object 30. In this embodiment, when the design program 100 determines that at least one of the jack 23 provided on the ground surface and the support column 22 connected to the jack 23 (in Figure 7(a), the support column 22 constituting the lowest frame 28) has interfered with the site object 30, it first deletes the interfering temporary scaffolding object 20 and the temporary scaffolding object 20 located above the said object. Specifically, as shown in Figure 7(a), when it is determined that the jack 23 provided on the ground surface, the support column 22 connected to the jack 23, and the lowest frame 28a have interfered with the site object 30, as shown in Figure 7(b), the ground surface portion 27 including the support column 22 and the jack 23, the frame 28a, and the frames 28b and 28c provided above (directly above) the interfering frame 28a are deleted. In other words, ensure that there is no temporary scaffolding object 20 above the site object 30.

[0056] Next, as shown in Figure 7(c), in the area where the temporary scaffolding object 20 was removed, the strip material 24 supporting the support column 22 is repositioned near the site object 30 (at a predetermined height from the top surface of the site object 30), and above the strip material 24, the work platform 21, strip material 24, and brace 25 (i.e., part of the frame 28) are repositioned to the same height as the parts that were not removed (in Figure 7(c), adjacent frame 28). Then, as shown in Figure 7(d), the support column 22 and jack 23 are repositioned in the area where the temporary scaffolding object 20 was removed. The support column 22 and jack 23 are repositioned so that their height from the reference plane P is the same as the temporary scaffolding object 20 that was not removed (in other words, they are shorter by the height of the site object 30 than the temporary scaffolding object 20 that was not removed), and the flange 22b of the support column 22 is positioned to fix the repositioned work platform 21, strip material 24, and brace 25. During the rearrangement of the support columns 22 and jacks 23, at least one of the following is performed: selection of a support column 22 from multiple types of support columns 22 stored in the memory unit 11, and adjustment of the height of the jacks 23. In this way, the height of the frame 28, such as the work platform 21, is adjusted as closely as possible, and the temporary scaffolding object 20 is reconstructed. Note that the rearrangement of the work platform 21, stripping material 24, and bracing 25 shown in Figure 7(c) and the rearrangement of the support columns 22 and jacks 23 shown in Figure 7(d) may be performed in reverse order.

[0057] Figure 8 is a schematic diagram showing the procedure for reconstructing the temporary scaffolding object 20 when the upper part of the temporary scaffolding object 20 interferes with the site object 30. In this embodiment, as shown in Figure 8(a), when the design program 100 determines that the temporary scaffolding object 20, which is positioned above the support column 22 (in Figure 8(a), for example, the support column 22 that constitutes the lowest frame 28) connected to the jack 23 provided on the ground surface, has interfered with the site object 30, it deletes the entire temporary scaffolding object 20 as shown in Figure 8(b).

[0058] Then, as shown in Figure 8(c), below (directly below) the site object 30, the work platform 21, the strip 24, and the braces 25 (i.e., part of the frame 28) are rearranged so that the height distance D between the uppermost work platform 21 (also referred to as work platform 21a) and the site object 30 is equal to or greater than the height at which site workers can work on the work platform 21a. Also, if there is a sufficient distance between the rearranged work platform 21 and the ground surface, the work platform 21, the strip 24, and the braces 25 are rearranged in the same manner, and the strip 24 supporting the support columns 22 is rearranged near the ground surface (at a predetermined height from the ground surface). Next, as shown in Figure 8(d), in the remaining area where the temporary scaffolding object 20 has not been rearranged, the work platform 21, the strip 24, and the braces 25 are rearranged to the same height. In addition, in areas that do not interfere with the site object 30 (i.e., not directly below the site object 30), the work platform 21, the stripping material 24, and the bracing 25 may be repositioned to a position higher than the work platform 21a.

[0059] Then, as shown in Figure 8(e), the support columns 22 and jacks 23 are rearranged. The support columns 22 and jacks 23 are rearranged so that the flange 22b of the support column 22 can fix the rearranged work platform 21, stripping material 24, and bracing 25. In areas where the support columns 22 and jacks 23 may interfere with the site object 30 (directly below the site object 30), they are rearranged to a height that leaves a predetermined gap so as not to interfere with the site object 30. When rearranging the support columns 22 and jacks 23, at least one of the following is performed: selection of a support column 22 from a plurality of types of support columns 22 stored in the memory unit 11 and adjustment of the height of the jacks 23, similar to when the lower part of the temporary scaffolding object 20 interferes with the site object 30. In this way, the height of the frame 28, such as the work platform 21, is matched as closely as possible, and the temporary scaffolding object 20 is reconstructed. Note that the rearrangement of the work platform 21, fabric material 24, and bracing 25 shown in Figures 8(c) and (d), and the rearrangement of the support columns 22 and jacks 23 shown in Figure 8(e) may be in reverse order.

[0060] As described above, in the design program 100 of this embodiment, when the interference detection function determines that a temporary scaffolding object 20 has interfered with a site object 30, at least the interfering temporary scaffolding object 20 is deleted, and in the area where the temporary scaffolding object 20 was deleted, at least one of selecting a support column 22 and adjusting the height of a jack 23 is performed to reposition the temporary scaffolding object 20 to match the position of the site object 30, thereby reconstructing the temporary scaffolding object 20. With this configuration, when a temporary scaffolding object 20 interferes with a site object 30, the program automatically deletes the interfering temporary scaffolding object 20 and repositions the temporary scaffolding object 20 to match the position of the site object 30 by performing at least one of selecting a support column 22 and adjusting the height of a jack 23. Therefore, the construction of temporary scaffolding can be easily performed in the program.

[0061] Furthermore, in the design program 100 of this embodiment, if the interference determination function determines that at least one of the jacks 23 provided on the ground surface and the support columns 22 connected to the jacks 23 interfere with the site object 30, the reconstruction of the temporary scaffolding object 20 is performed by selecting the support columns 22 and adjusting the height of the jacks 23 so that the height of the work platform 21 to be repositioned matches the height of the work platform 21 that is not deleted, thereby repositioning the temporary scaffolding object 20. Thus, the program makes it easy to construct temporary scaffolding with a uniform height of work platform 21.

[0062] Furthermore, in the design program 100 of this embodiment, if the interference determination function determines that a temporary scaffolding object 20 positioned above a support column 22 connected to a jack 23 provided on the ground surface has interfered with a site object 30, the reconstruction of the temporary scaffolding object 20 involves selecting a support column 22 and adjusting the height of the jack 23 to reposition the temporary scaffolding object 20 so that the height distance D between the work platform 21 to be repositioned and the site object 30 is equal to or greater than the height at which a site worker can work on the uppermost work platform 21 (work platform 21a). Thus, the program facilitates the construction of temporary scaffolding that ensures workspace for site workers.

[0063] Furthermore, in the design program 100 of this embodiment, if the interference determination function determines that a temporary scaffolding object 20 positioned above a support column 22 connected to a jack 23 provided on the ground surface interferes with a site object 30, the reconstruction of the temporary scaffolding object 20 involves deleting the entire temporary scaffolding object 20 and rearranging the temporary scaffolding object 20 by selecting a support column 22 and adjusting the height of the jack 23 so that the height of the work platform 21 is uniform in the horizontal direction. Thus, the program makes it easy to construct temporary scaffolding with a uniform height of the work platform 21.

[0064] Next, modifications of this embodiment will be described. The following modifications are also within the scope of the present invention, and it is possible to combine the configurations shown in the modifications with the configurations described in the above embodiments, or to combine the configurations described in the following different modifications.

[0065] <Example 1> In the above embodiment, if the design program 100 determines in its interference determination function that at least one of the jack 23 provided on the ground surface and the support column 22 connected to the jack 23 has interfered with the site object 30, it deletes the ground portion 27 including the support column 22 and the jack 23, the interfering frame 28a, and the frames 28b and 28c provided above the frame 28a, and then rearranges them. However, the design program 100 may, in its interference determination function, determine that at least one of the jack 23 provided on the ground surface and the support column 22 connected to the jack 23 has interfered with the site object 30, and then delete only the interfering area (support column 22 and jack 23) and rearrange them. Furthermore, it is preferable that the height of the work platform 21 to be rearranged and the work platform 21 that is not deleted are the same, but the heights of these work platforms 21 do not have to be the same.

[0066] Similarly, if the design program 100 determines in its interference detection function that a temporary scaffolding object 20 positioned above a support column 22 connected to a jack 23 on the ground surface interferes with a site object 30, it may delete only the temporary scaffolding object 20 positioned directly below the site object 30 and rearrange the work platform 21 so that the height distance between the work platform 21 and the site object 30 is greater than or equal to the height at which a site worker can work on the uppermost work platform 21. In this case as well, it is preferable that the height of the rearranged work platform 21 and the work platform 21 that is not deleted are the same, but the heights of these work platforms 21 do not have to be the same. In other words, the heights of the work platforms 21 do not have to be the same in the horizontal direction.

[0067] <Modification 2> In the above embodiment, the design program 100 changes its control depending on whether the interference determination function determines that at least one of the jack 23 provided on the ground surface and the support column 22 connected to the jack 23 has interfered with the site object 30, or whether the interference determination function determines that a temporary scaffolding object 20 positioned above the support column 22 connected to the jack 23 provided on the ground surface has interfered with the site object 30. The design program 100 is not limited to this, and may include, for example, a first mode and a second mode that can be arbitrarily switched by the user on the design screen W.

[0068] In the first mode, the interfering temporary scaffolding object 20 and the temporary scaffolding object 20 located below it (directly below) are deleted and not repositioned. Above the site object 30 (directly above), the temporary scaffolding object 20 is repositioned by selecting a support column 22 and adjusting the height of the jack 23 so that the height of the work platform 21 to be repositioned matches that of the work platform 21 that is not deleted. In other words, in the first mode, regardless of the location of the interference with the site object 30, the temporary scaffolding object 20 located directly below the site object 30 is deleted and not repositioned, while the temporary scaffolding object 20 located directly above the site object 30 is reconstructed in the same manner as when the interference detection function determines that at least one of the jack 23 provided on the ground surface and the support column 22 connected to the jack 23 has interfered with the site object 30.

[0069] On the other hand, in the second mode, the interfering temporary scaffolding object 20 and the temporary scaffolding object 20 positioned above it (directly above) are not deleted and repositioned. In other areas, the temporary scaffolding object 20 is repositioned by selecting a support column 22 and adjusting the height of the jack 23, such that the height distance D between the uppermost work platform 21, which is repositioned below the site object 30, and the site object 30 is greater than or equal to the height at which site workers can work on the uppermost work platform 21. In other words, in the second mode, regardless of the position where the site object 30 interfered, the temporary scaffolding object 20 located directly above the site object 30 is not deleted and repositioned. In other areas, reconstruction is performed in the same manner as when the interference detection function determines that a temporary scaffolding object 20 positioned above a support column 22 connected to a jack 23 provided on the ground surface has interfered with the site object 30. Even with this configuration, the same effects as in the above embodiment are achieved.

[0070] Although embodiments of the present invention have been described above, these embodiments only represent a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.

[0071] The design program 100 according to this embodiment may be provided by a storage medium readable by the information processing device 10, or it may be provided via a network line. Furthermore, the distance D in the height direction between the uppermost work platform 21a and the site object 30 may be a fixed value or a value with a certain range. [Explanation of Symbols]
