Description

[Technical field]

[0001] The present invention relates to a scaffolding design support tool and a scaffolding design method that support the design of scaffolding to be installed around a building. [Background technology]

[0002] Traditionally, at construction sites, scaffolding is set up around the target building to carry out various tasks. In order to set up this scaffolding, it is necessary to design the installation range and dimensions of each part in advance according to the shape of the building, the dimensions of each part, the contents of the work (tasks), etc., and calculate the quantity of each type of material required to construct the scaffolding. Therefore, it is possible to use a 3D model creation system (3D-CAD, etc.) to design the scaffolding. However, conventional 3D model creation systems can only depict the three-dimensional shape of the structure, so in order to obtain detailed information such as the types and quantities of various components required to actually construct the scaffolding, as well as the joint structures between the components, it was necessary to use 2D drawings in addition. In contrast, the currently popular 3D model creation system known as BIM (Building Information Modeling) not only allows you to draw a building in 3D model like conventional drafting software, but also allows you to add information necessary for actual construction such as the material, price, and joint structure of each part that makes up the building. This not only makes it possible to create more accurate construction plans than before, but also allows the additional information necessary for construction to be managed as electronic data, and makes it possible to modify the content within electronic devices (computers, personal computers), thereby reducing costs. As an example of using such BIM-compatible three-dimensional CAD software or BIM software to design temporary scaffolding and to estimate the quantity of scaffolding components that make up the temporary scaffolding, for example, Patent Document 1 discloses a design and estimation support system and design and estimation method for temporary scaffolding that uses a computer on which three-dimensional CAD software, estimation software, and coordinate calculation software are installed.

[0003] [Patent Document 1] Patent Publication No. 2019-75028 Summary of the Invention [Problem to be solved by the invention]

[0004] However, as in Patent Document 1, in the design of temporary scaffolding using BIM-compatible three-dimensional CAD software or BIM software, various information necessary for construction can be handled, but since drawing and inputting information for each component are complicated, drawing work requires a lot of time, the amount of work increases, the burden on the drafter (engineer) increases, and input errors are likely to occur. In addition, when displaying (drawing) details of the created drawing or when additional information increases and the amount of data handled becomes large, the system operation slows down and workability deteriorates. Furthermore, since the operation is more complicated than conventional 3D-CAD and it takes a considerable amount of time to reach a certain level of drawing skill, there is a problem that engineers cannot be trained quickly and the number of engineers who can handle it is limited.

[0005] The present invention has been made in consideration of the above circumstances, and has an object to provide a scaffolding design support tool and a scaffolding design method which allow a drafter to design scaffolding with simple operations without having to learn complex operations, which significantly reduces the amount of input work, makes input errors less likely to occur, and reduces the workload, while also significantly reducing the load when drawing drawings and processing data, making work more comfortable and enabling the quantity of scaffolding components to be accurately calculated. [Means for solving the problem]

[0006] A scaffolding design support tool according to a first invention in accordance with the above object is a scaffolding design support tool that operates on a 3D model creation system and supports the design of scaffolding to be installed around a target building, a simplified model display means for displaying a simplified model of the scaffolding by arranging each box, which is displayed in a line diagram corresponding to each scaffolding unit constituting the scaffolding, at a designated position on a screen on which the building is displayed; A member information storage means for storing component information of each member constituting each scaffolding unit by linking it to each box body corresponding to each scaffolding unit; The scaffolding further includes a component calculation means for calculating the quantity of each component required to construct the scaffolding from the number of boxes in the simple model displayed on the screen, based on the component component information linked to each box and stored in the component information storage means.

[0007] In the scaffolding design support tool of the first invention, the width, depth and height dimensions of each of the boxes are displayed expandably on the screen by the simple model display means, and the component information storage means can change the component component information linked to each of the boxes in conjunction with the expansion and contraction of each of the dimensions of each of the boxes on the screen.

[0008] In the scaffolding design support tool according to the first invention, the component member information is preferably the number, dimensions and arrangement of the components constituting each of the scaffolding units.

[0009] In the scaffolding design support tool of the first invention, when the simple model includes multiple types of box bodies differing in any of the dimensions of width, depth, and height, the component estimation means can estimate the quantity of each of the components required to construct the scaffolding for each type of box body.

[0010] In the scaffolding design support tool of the first invention, it is preferable to have a detailed drawing creation means for creating each scaffolding unit detailed drawing showing details of each scaffolding unit corresponding to each box body based on the constituent member information of each of the members stored in the member information storage means, a detailed model creation means for creating a detailed model of the scaffolding by replacing each of the boxes in the simple model with the each scaffolding unit detailed drawing created by the detailed drawing creation means, and a display switching means for displaying the simple model or the detailed model on the screen.

[0011] A scaffolding design method according to a second invention in accordance with the above object is a scaffolding design method for designing scaffolding to be installed around a target building using a 3D model creation system, a simplified model creation process for creating a simplified model of the scaffolding by arranging each box, which is displayed in a line diagram corresponding to each scaffolding unit constituting the scaffolding, at a designated position on a screen on which the building is displayed; The method includes a component calculation process for calculating the quantity of each component required to construct the scaffolding from the number of boxes in the simple model displayed on the screen based on component information of each component that constitutes each scaffolding unit that is linked to each box in advance.

[0012] In the scaffolding design method of the second invention, the component estimation process can estimate the quantity of each component required to construct the scaffolding for each type of box when the simple model includes multiple types of box bodies differing in any of the dimensions of width, depth, and height. Effect of the Invention

[0013] According to the scaffolding design support tool of the first invention, a drafter can easily design a scaffolding by simply arranging boxes using the simple model display means, and after designing, the quantity of each component required to construct the scaffolding can be accurately calculated using the component calculation means, allowing a highly accurate construction plan to be created with little workload.

[0014] In the scaffolding design support tool of the first invention, the width, depth and height dimensions of each box are displayed expandably on a screen by a simple model display means, and the component information storage means changes the component component information linked to each box in conjunction with the expansion and contraction of each dimension of each box on the screen.The drafter can design the scaffolding by placing each box in the desired position while expanding or contracting each dimension of each box on the screen as appropriate, and the quantity of each component required to construct the scaffolding is accurately calculated by the component calculation means based on the component component information changed by the component information storage means in conjunction with the expansion and contraction of each dimension of each box.

[0015] In the scaffolding design support tool of the first invention, when the component information is the number, dimensions and arrangement of each component that constitutes a scaffolding unit, the component information regarding the number, dimensions and arrangement of components actually required to constitute each scaffolding unit is automatically changed (updated) in conjunction with the expansion and contraction of each dimension of each box on the screen, stored in the component information storage means, and accurately reflected in the calculation by the component calculation means.

[0016] In the scaffolding design support tool of the first invention, when a simple model contains multiple types of box bodies differing in any of the dimensions of width, depth, or height, if the component calculation means calculates the quantity of each component required to construct the scaffolding for each type of box body, the quantity of all components required to construct the scaffolding is accurately calculated without omission, even if the scaffolding is composed of multiple types of scaffolding units.

[0017] In the scaffolding design support tool of the first invention, when it has a detailed drawing creation means for creating each scaffolding unit detailed drawing showing details of each scaffolding unit corresponding to each box body based on the constituent member information of each member stored in the member information storage means, a detailed model creation means for creating a detailed model of the scaffolding by replacing each box body in the simple model with each scaffolding unit detailed drawing created by the detailed drawing creation means, and a display switching means for displaying a simple model or a detailed model on a screen, the drafter can create each scaffolding unit detailed drawing simply by considering the dimensions and arrangement of each box body corresponding to each scaffolding unit, and by switching the display of the simple model and the detailed model as necessary during drawing, the load of displaying (drawing) the detailed model on the screen can be significantly reduced, while efficiently designing scaffolding while checking the scaffolding unit detailed drawings at key points, allowing the drafter to work comfortably.

[0018] According to the scaffolding design method of the second invention, the drafter can easily design the scaffolding by simply arranging the boxes in the simple model creation process, and after the design is completed (after the simple model is created), the quantity of each component required to construct the scaffolding can be accurately calculated in the component estimation process, allowing a highly accurate construction plan to be created with little workload.

[0019] In the scaffolding design method of the second invention, when the simplified model contains multiple types of box bodies that differ in any of the dimensions of width, depth, or height, if the component estimation process estimates the quantity of each component required to construct the scaffolding for each type of box body, the quantities of all components required to construct the scaffolding are accurately estimated without omission, even if the scaffolding is composed of multiple types of scaffolding units.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Next, an embodiment of the present invention will be described with reference to the attached drawings to facilitate understanding of the present invention. A scaffolding design support tool 10 according to an embodiment of the present invention shown in Fig. 1 operates on a 3D model creation system (3D-CAD, etc.) to support the design of scaffolding to be installed around a target building. As shown in FIG. 1, the scaffolding design support tool 10 includes a simple model display means 11, a member information storage means 12, and a member cost calculation means 13. As shown in FIG. 2, the simple model display means 11 displays a simple model 18 of the scaffolding by arranging each box 16, 16a, 17, 17a displayed in a line diagram corresponding to each scaffolding unit constituting the scaffolding at a designated position on a screen on which a building 15 is displayed. Here, the boxes 16a and 17a correspond to each scaffolding unit arranged at the lowest position (lowest step). The type of box used in the simple model and the number and arrangement of boxes for each type are not limited to this embodiment, and the designer can consider the type (structure, dimensions) and arrangement of the scaffolding unit actually used according to the shape, structure, dimensions, etc. of the building 15, and arrange each box corresponding to each scaffolding unit at a desired position. Note that even boxes of the same dimensions on the simple model may correspond to different types of scaffolding units, in which case the number, dimensions, and arrangement of each member constituting each scaffolding unit are different.

[0022] The component information storage means 12 stores component information of each component that constitutes each scaffolding unit, linked to each box 16, 16a, 17, 17a corresponding to each scaffolding unit. In addition, the component calculation means 13 can calculate the quantity of each component required to construct the scaffolding from the number of boxes 16, 16a, 17, 17a in the simplified model 18 displayed on the screen, based on the component information linked to each box 16, 16a, 17, 17a and stored in the component information storage means 12.

[0023] Here, the component information is the number, dimensions, and arrangement of each component constituting each scaffolding unit. The width, depth, and height dimensions of each box body 16, 16a, 17, and 17a are displayed expandably on the screen by the simplified model display means 11, and the component information storage means 12 can change the component information linked to each box body 16, 16a, 17, and 17a in conjunction with the expansion and contraction of each dimension of each box body 16, 16a, 17, and 17a on the screen. In addition, when multiple types of boxes 16, 16a, 17, and 17a with different dimensions of width, depth, and height are included in the simplified model 18 (here, the dimensions (width) of the box body 16 and the box body 17 are different, and the dimensions (width) of the box body 16a and the box body 17a are different), the component calculation means 13 can calculate the quantity of each component required for constructing the scaffolding for each type of box body 16, 16a, 17, and 17a.

[0024] Therefore, the designer can design the scaffolding by appropriately arranging each box 16, 16a, 17, 17a without being too concerned about the type (configuration) of the actual scaffolding unit. Then, the designer can simply expand or contract the dimensions of each box on the screen, and the number, dimensions, and arrangement of each component that constitutes the scaffolding unit are automatically changed in conjunction with the expansion or contraction of the dimensions of each box, and the component information linked to each box is updated, so that the exact quantity of each component required to construct the scaffolding is instantly calculated.

[0025] Furthermore, the scaffolding design support tool 10 includes a detailed drawing creating means 20, a detailed model creating means 21, and a display switching means 22, as shown in FIG. The detailed drawing creating means 20 can create a detailed scaffolding unit drawing showing details of each scaffolding unit corresponding to each box body based on the constituent member information of each member stored in the member information storing means 12. The detailed scaffolding unit drawing 23 in FIG. 3 shows details of the scaffolding unit at the lowest position corresponding to the box body 16a. The scaffolding unit shown in the detailed scaffolding unit drawing 23 is composed of a jack base 25, a base 26, an arm 27, a building site 28, a work floor 29, a handrail 30, a center 31, a diagonal brace 32, and a baseboard 33, but this is only an example, and the type and combination of members constituting the scaffolding unit, as well as the number, dimensions, and arrangement of each member, are appropriately selected depending on the installation position of the scaffolding unit, etc. For example, the jack base 25 and the base 26 are included only in the scaffolding unit placed at the lowest position, and in each scaffolding unit, the arm 27, the handrail 30, the center 31, the diagonal brace 32, and the baseboard 33, etc. are appropriately added or omitted. Furthermore, as explained above, when the dimensions of each box are expanded or contracted on the screen, the component information of each component (the number, dimensions and arrangement of each component constituting the scaffolding unit) stored in the component information storage means 12 is automatically changed in conjunction with this, and accordingly, detailed views 23a, 23b of the scaffolding unit after expansion or contraction are created, as shown in Figures 4 and 5, respectively.

[0026] The detailed model creating means 21 can create a detailed model (not shown) of the scaffolding by replacing each box in the simplified model with a detailed drawing of each scaffolding unit created by the detailed drawing creating means 20. The display switching means 22 can display the simple model 18 or the detailed model on the screen according to the designer's instruction. Since it takes time to display (draw) a detailed model, the designer usually works using the simple model 18, and when it is necessary to check the detailed structure of each scaffolding unit, the designer can work comfortably with a significantly reduced drawing load by using the detailed model.

[0027] As described above, the scaffolding design support tool 10 includes the simple model display means 11, the member information storage means 12, the member cost calculation means 13, the detailed drawing creation means 20, the detailed model creation means 21, and the display switching means 22, and this scaffolding design support tool 10 causes a computer on which a 3D model creation system (3D-CAD or the like) and its software are installed and executed to function as the simple model display means 11, the member information storage means 12, the member cost calculation means 13, the detailed drawing creation means 20, the detailed model creation means 21, and the display switching means 22. As for the form of the computer, a desktop type or a notebook type is preferably used, but is not limited thereto.

[0028] Here, data of each box used in the simple model is created in a programming language (e.g., GDL language: Geometric Description Language) installed in the software of a 3D model creation system (3D-CAD, etc.). Then, as data of each box, component information of each member constituting each scaffolding unit corresponding to each box is added in advance, and the component information is linked to each box and stored.

[0029] A scaffolding design method using the scaffolding design support tool 10 will be described below. A drafter can create a simplified model 18 by placing each of the boxes 16, 16a, 17, and 17a around a building 15 as shown in Fig. 2 by specifying with an input means such as a mouse or a touch pen on the screen of a computer on which a 3D model creation system equipped with a scaffolding design support tool 10 is running. The dimensions of the width, depth, and height of each of the boxes 16, 16a, 17, and 17a are displayed on the screen in a stretchable manner by the simplified model display means 11. The drafter can stretch each of the boxes 16, 16a, 17, and 17a by specifying and moving a predetermined position (vertex or side) of each of the boxes 16, 16a, 17, and 17a on the screen with the input means. The dimensions of each of the boxes 16, 16a, 17, and 17a can be entered numerically on the input screen to expand or contract each of the boxes 16, 16a, 17, and 17a, or the box body to be used can be selected and arranged from multiple types of boxes with different dimensions that are prepared (stored) in advance (this is the simple model creation process).

[0030] When the creation of the simplified model 18 is completed, the quantity of each component required to construct the scaffolding is calculated from the number of boxes 16, 16a, 17, 17a in the simplified model 18 displayed on the screen by the component calculation means 13 based on the component information of each component that constitutes each scaffolding unit previously linked to each box 16, 16a, 17, 17a. In the component calculation step, when the simplified model 18 includes multiple types of boxes 16, 16a, 17, 17a that differ in any one of the dimensions of width, depth, and height, the quantity of each component required to construct the scaffolding can be calculated for each type of box 16, 16a, 17, 17a (the above is the component calculation step).

[0031] As described above, after the drafter creates the simple model 18 by arranging the boxes 16, 16a, 17, and 17a, the exact quantity of each component is automatically calculated based on the determined component information, so that the drafter does not need to input detailed component information such as the number, dimensions, and arrangement of each component that constitutes each scaffolding unit one by one as in the past, and can comfortably design the scaffolding with extremely simple procedures, reducing the workload and eliminating input and calculation errors. In addition, since there is no need to master complicated operations for designing the scaffolding, even engineers with little drafting experience can engage in scaffolding design as a drafter, and the time required for training engineers is reduced.

[0032] Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations described in the above embodiments, and also includes other embodiments and variations that can be considered within the scope of the matters described in the claims.
