JP3965165B2 - System for assigning building materials to the outer wall of a house - Google Patents

Description

  The present invention relates to a system for optimally allocating building materials to an outer wall surface of a house, and in particular, a building material allocating system capable of performing a simulation for automatically and optimally allocating building materials to an outer wall surface of a house on a computer. It is about.

  When a customer constructs a house, he creates a design drawing and selects interior and exterior designs according to the design drawing. As the exterior design, after determining the position of openings such as windows and the shape of the roof (gable, dormitory, etc.), external wall materials and roof materials are selected. The design of the outer wall and the roof is expressed by arranging a plurality of outer wall materials and roof material base materials having various patterns, patterns, and colors having various shapes and sizes.

  Designers, construction companies, etc. make up designs that have exterior wall materials and roofing materials appropriately pasted on the exterior of the design drawings, and present several proposals to customers as images of the completion of housing construction. It is common to choose. However, due to recent advances in drawing processing software, customers themselves select base materials from catalogs of outer wall materials and roof materials, and paste them in the desired manner on the appearance of design drawings displayed on the screen to complete the construction. You can also create images.

  Patent Literature 1 describes a system that realizes a simulation for generating an exterior design of a house as described above between a server and a client connected via a network. In the system of Patent Document 1, a customer acquires data such as building material images necessary for simulation from a server device using a client device, and pastes it on house image data or the like held in the client device. It is said that it is possible to simulate the appearance design generation.

  By the way, the building materials (outer wall materials) used for the outer wall surface of a house are usually specified as 9 length x 1.5 width (2730mm x 455mm) or 9 length x 3 width (2730mm x 910mm). Manufactured in modular units with dimensions. The prescribed dimension of the outer wall material is determined in accordance with the dimension of the base material of the outer wall, and the dimension of the base material is determined from the viewpoints of structural strength and material strength. In practice, however, the building material is often cut in the longitudinal direction in order to accurately align it with the corners and openings at the construction site, so the longitudinal direction of the building material product is longer than the required dimension ( For example, it is made into a 1030 product with a length of 3030 mm.

  Conventionally, a construction shop or the like assigns building materials of a prescribed size to the outer wall surface of a house based on a design drawing. For the allocation of building materials, consider the dimensions and shape of the outer wall surface of the house, minimize the end material (loss) generated by cutting the building material, and consider the design of the building material. The location of the joints of the building materials must be determined so as not to impair the beauty of the walls. In particular, wet and dry joint materials are applied to the joints in the longitudinal direction of building materials in order to prevent water leakage and joint expansion and contraction. The aesthetics of the outer wall of the house are greatly affected by the position of the. Furthermore, since there are openings such as windows and entrances on the outer wall surface of the house, these positions and dimensions must be taken into consideration. When cutting the building material in accordance with the opening, it is necessary to be careful that the horizontal or vertical width of the building material does not become too small. This is because if a building material having a too small width is used, strength failure may occur.

  Therefore, it is necessary to allocate the building materials to the outer wall surface of the house in consideration of various points such as aesthetics, water leakage prevention function, ensuring strength, and cutting loss reduction.

Patent Document 2 discloses a method for allocating building materials to the outer wall surface of a house, in which standardized building materials are arranged, and an allocation simulation is performed to cut off unnecessary portions of building materials such as openings, and is generated by cutting A method for allocating building materials is described in which a portion that is less than the limit on the strength of the building material to be detected is detected, and an arrangement in which this portion does not occur or an arrangement in which the number of the portions is minimized is determined as the optimum arrangement.
Japanese Patent Laid-Open No. 2002-41879 (in particular, summary, paragraphs 0028 to 0029) Japanese Patent No. 3466536 (in particular, claims 1 and 2)

  As described above, the most appropriate allocation method for building materials is assigned to the outer wall surface of the house in consideration of the occurrence of cutting loss of the building materials due to the presence of openings, a decrease in strength, and changes in aesthetics due to seam positioning. Since it is necessary to search for it, the person in charge of a construction company has been relying on experience and intuition. Arrangement of building materials and positioning of joints can be carried out in various ways, and the aesthetics of each house can be slightly different, but in reality, a single allocation method determined by the person in charge of the construction company etc. However, the current situation is that the customer cannot select the allocation method (Problem 1).

  Also, during construction, the building materials are cut and used according to the position and dimensions of the openings on the outer wall of the house, but the cut ends are discarded, so this loss rate is expected when ordering building materials. It is common to place a large order. However, as described above, only building materials with specified dimensions such as length 9 × width 1.5 and length 9 × width 3 are supplied. Depending on the case, a large part of the building material having a specified size must be cut and discarded. If the loss rate of building materials increases, not only the cost of building materials but also the cost of collecting discarded scraps will increase, and the construction period will become longer if there is a lot of cutting work for building materials. Wants to be as low as possible (Problem 2).

  In the building material allocating method described in Patent Literature 2, only the problem of securing the building material strength is a problem, and no means for solving the above-described problems is presented.

  Therefore, regarding the allocation of building materials to the outer wall surface of the house, several allocation methods (such as arrangement of building materials and positioning of seams) are presented to the customer, and the customer's view of the aesthetics of the house (Problem 1) It is an object of the present invention to realize on a computer a system capable of performing a simulation for comparing and examining each allocation method from the viewpoint of reducing the loss rate (Problem 2) and determining which one to employ.

  As a result of diligent research in view of the above-mentioned problem, the present inventor can prepare a plurality of building material units having the same type of building material and different dimensions, and perform allocation by combining them, and can also allocate by a plurality of allocation methods. I came up with the idea of realizing a system capable of simulation on a computer.

That is, the present invention is a building material allocation system that allocates building materials to the outer wall surface of a house, and includes a design drawing file including design drawing data of a house, and a product name, size / shape, and the same kind of building material for each building material. data for different building materials unit dimensions, and a database for storing building materials file containing the image data of the building materials, manages the data of the design drawing file and building materials file of the database, using these data, the design drawings A design management unit that provides a client device with a construction simulation function for applying a building material image included in the building material file to an arbitrary design drawing included in the file to generate a housing construction image, and a client via the network Interface to enable communication with the device A network interface unit is a chair for each outer wall surface of the construction image generated by the working simulation, while providing a simulation function to assign a building material having a predetermined size, caused by allocation of該建material, the allocated該建material It is equipped with a building material allocating section that calculates the amount of loss or loss rate due to cutting and the number of allocated building material units for each building material and outputs the result as the building material allocation result. Is a vertical line arranged at a certain interval in the horizontal direction with respect to the outer wall surface, and the distance between the vertical lines is the maximum value of the length in the longitudinal direction of the building material unit. The reference line, which is the reference for allocating building materials in the longitudinal direction, was determined to match , Against the outer wall surface in the working image, in which the allocation is made by combining different building materials unit dimensions a same type of building material to provide a building material allocation system characterized Rukoto.

  In the building material allocation system of the present invention, the building material unit has a dimension that is an integral multiple of the basic dimension in the longitudinal direction. For example, if the basic dimensions are 3 and 6 and 9 building materials units are prepared, an appropriate building material unit can be efficiently allocated according to the dimensional shape of the allocated portion.

In the building material allocating system of the present invention, the building material is allocated in such a manner that the vertical bisector of the horizontal length of the outer wall of the house matches the vertical bisector of the horizontal length of the building material. The method of allocating, the method of allocating building materials so that the vertical bisector of the horizontal length of the outer wall surface of the house matches the joint between the building materials in the horizontal direction, and from one end to the other end of the outer wall surface in the horizontal direction toward characterized thereby set one of the methods of allocating building materials to the customer.

  Thereby, it is possible to perform an allocation simulation that compares a plurality of allocation methods and examines which one to employ.

  In the building material allocation system of the present invention, the building material allocation unit outputs the number of allocations of each building material unit as a building material allocation result. Further, the building material allocating unit calculates a loss amount or a loss rate due to cutting of the building material, and outputs the result as a building material allocation result.

  Thereby, it becomes possible to select the allocation method in consideration of not only the beauty but also the size of the cutting loss of the building material. The cutting loss amount of the building material can be represented by, for example, the total area of the design surface of the cut building material.

In the building material allocating system of the present invention, the design management unit manages the design drawing file of the database and the data of the building material file, and uses these data for any design drawing included in the design drawing file. A construction simulation function for generating a construction image of a house by applying an arbitrary construction material image included in the construction material file is provided to the client device .

  Customers can use a client device to perform a construction simulation in which building materials are pasted on the design drawings of their homes.

The building material allocation system according to the present invention further includes an order management unit that receives an order for building materials based on a building material allocation result by the building material allocation unit.

  If the order management unit acquires the building material allocation result output by the building material allocation unit, it can be handled as it is as the order data, so that the order can be processed efficiently.

The present invention also provides a building material allocation program for causing a computer to function as the above-described building material allocation system .

  As described above, according to the present invention, on the computer, several allocation methods (such as arrangement of building materials and positioning of seams) are presented to the customer, and the customer can view the aesthetics of the house as well as the building materials. From the standpoint of reducing the loss rate, a construction material allocation system is realized that performs a simulation to compare and examine each allocation method and decides which one to employ. With this system, the loss rate of building materials in residential buildings is reduced, and environmental burdens are reduced and residential building costs are reduced.

[4] Usage Form of Building Material Allocation System Next, a usage pattern of the building material allocation system of the present embodiment configured as described above and operations of the client device and the server device will be described in detail. FIG. 5 is a flowchart schematically showing a processing flow when a customer or the like uses this system from a client device.

  A customer or the like who wants to use this system first creates a design drawing of a house to be built by the design drawing editing software 412 of the client device, and uploads the design drawing data to the server device of the building material manufacturer (step S51). ). By the way, the aspect of the uploaded design drawing data may differ depending on the type of design drawing editing software 412 possessed by the client device. For example, when the Architrend 21 is used, the part of the house in the design drawing is recognized at the drafting stage, and this design drawing data can be handled as it is in this system.

  On the other hand, in the case of general-purpose CAD software or the like, since the part of the house in the design drawing is not recognized, the customer etc. uploads the design drawing data to the server device, and then the part, shape, size, etc. of the house in the drawing Must be confirmed. Examples of display screens for performing this work are shown in FIGS. This function is provided by the design management unit 206. The design drawing data in a form that can be handled in this system is stored in the design drawing file 222 of the database 220 in association with the customer information. Further, it is assumed that the customer has uploaded predetermined customer information to the server device in advance.

  Subsequently, the customer can perform a construction simulation in which the building material is pasted on the design drawing uploaded to the server device (step S52). The construction image generated by the construction simulation is stored in the construction image file 224 of the database 220 in association with customer information and design drawing data. Furthermore, building material allocation simulation can be performed based on the generated construction image (step S53). The building material allocation simulation result data can be stored in the construction image file 224 of the database 220 in association with the construction image. As shown in FIG. 5, after the design drawing data is uploaded to the server device or the construction simulation is completed, the state is saved in the database 220 of the server device or the storage unit 402 of the client device. Processing can also be terminated. In this case, the subsequent processing can be continued using data stored later. Hereinafter, the process in the construction simulation in step S52 and the process in the building material allocation simulation in step S53 will be described in detail.

[4.1] Construction Simulation FIG. 8 is a flowchart showing in detail the processing flow of the construction simulation described above. Each step of the construction simulation described below is executed by the design management unit 206 of the server device, and a simulation image is appropriately displayed on the display unit 404 via the user interface unit 410 of the client device, and an input unit The customer's operation received by 406 is transmitted to the design management unit 206 of the server device. In addition, about the image display in construction simulation, it can process by software, such as WEB3D marketed.

  First, design drawing data to be subjected to construction simulation is acquired (step S81). The design drawing data is uploaded from the client device and stored in the design drawing file 222 of the database 220. An elevation of the acquired design drawing data is displayed on the display unit 404 of the client device (step S82). An example of the screen displayed on the client device at this time is shown in FIG. Here, an elevation view representing one side of the house is displayed so that the building material pasting operation is facilitated, but a perspective view or the like may be displayed.

  On the screen shown in FIG. 9, the customer or the like selects a region to which the building material is to be pasted (Step S83), and uses the building material pasting tool to select a building material to be pasted on the selected region (Step S84). An example of a screen displaying the building material pasting tool is shown in FIG. The composition and layout size of the building material are selected on the screen 1 in FIG. 10, the pattern is selected on the screen 2, the color is selected on the screen 3, and the design of the building material is confirmed. The operation of selecting a building material is not limited to this example, and is performed in an appropriate mode (for example, a catalog format) according to the data configuration of the building material file 223 stored in the database 220 of the server device. do it. In addition, as described above, in this system, since the part of the house in the design drawing data is recognized, the selection of the pasting area such as the curtain, the eaves, the windbreak, the exit corner, the entrance corner, etc. This can be done for each part, and when affixing the building material, the building material to be affixed can be selected from the building materials suitable for the part to be used. Although FIG. 10 shows an example in which the building material is horizontally pasted, the customer may be able to select whether to vertically or horizontally.

  When the building material pasting operation is completed, an image with the building material pasted is displayed in the elevation view shown in FIG. 9, so that the customer or the like can select another region and perform the building material pasting operation. Yes (step S85). When all the building material pasting operations are completed, the customer or the like can further display an elevation view of the other side of the design drawing and similarly perform the building material pasting operation (step S86). When the building material pasting operation is completed for all the design drawings, a construction image in which the building material images are combined with the design drawings is displayed (step S87). An example of a screen displaying a construction image is shown in FIG. In FIG. 11, only an elevation view of one side of the design drawing is displayed, but in addition to this, a perspective view or the like may be displayed.

  The customer can store or print the construction image generated in this way in his / her client device or server device. When the construction image is stored in the server device, the construction image is stored in the construction image file 224 of the database 220 as construction image data.

  In using this system, construction simulation is not an essential process. For example, a usage form in which a construction image created in a client device is uploaded to a server device and a next building material allocation simulation is executed is also possible.

[4.2] Building Material Allocation Simulation FIG. 12 is a flowchart showing in detail the flow of processing for performing building material allocation simulation based on the construction image generated by the construction simulation. Each step of the building material allocation simulation described below is executed by the building material allocation unit 208 of the server device, and the customer needs the input unit 406 while viewing the screen displayed on the display unit 404 of the client device. The operation can be performed. In this embodiment, allocation is performed such that the longitudinal direction of the building material coincides with the horizontal direction (horizontal pasting), but in the same manner, the allocation is performed such that the longitudinal direction of the building material coincides with the vertical direction. It can also be done (vertical paste).

  First, a construction image generated by construction simulation is acquired (step S121). The construction image is stored in the construction image file 224 of the database 220 or the storage unit 402 of the client device. The customer selects one outer wall surface of the construction image and displays it on the display unit 404 of the client device (step S122). This outer wall surface display screen is, for example, a screen as shown in FIG.

  The customer sets a reference line as a reference for allocating building materials in the longitudinal direction to the displayed outer wall surface (step S123). In the present embodiment, the reference line can be set by any one of the three methods shown in FIGS. The reference lines are vertical lines that are arranged at regular intervals in the horizontal direction, and the distance between the reference lines is determined so as to coincide with the maximum value of the length in the longitudinal direction of the building material unit. In the present embodiment, the length in the longitudinal direction of the building material is 9 scales (2730 mm) at the maximum, so the distance between the reference lines is 2730 mm.

  In the first method shown in FIG. 13, the center line (vertical bisector) of the horizontal length of the outer wall surface of the house matches the center line (vertical bisector) of the horizontal length of the building material. This is a method of allocating building materials and is generally called core allocation. First, after allocating one building material at the center, the building material is allocated toward the left end and the right end. The second method shown in FIG. 14 is such that the center line (vertical bisector) of the horizontal length of the outer wall surface of the house coincides with the horizontal seam of the building material (joint portion between the building materials in the horizontal direction). This is a method for allocating building materials, and is generally referred to as center joint distribution. First, after allocating the two building materials so that the horizontal seam of the building materials is aligned with the center line of the horizontal length of the outer wall surface of the house, the building materials are allocated toward the left end and the right end. The third method shown in FIG. 15 is a method in which a reference line is taken at the left end (or right end) of the outer wall surface of the house, and building materials are assigned from here toward the right end (or left end).

  When the customer sets the reference line, the building material is automatically assigned to the outer wall surface in the construction image (step S124). As described above, in the present embodiment, a building material unit having a length of 9 measures × width of 1.5 measures, a length of 9 measures × width of 1.5 measures, a building material unit of length 9 measures × width of 1.5 measures. Since a building material unit having a length and a building material unit having a length of 3 × 1.5 width are prepared, allocation is performed by optimally combining these building material units (details will be described later). After automatic allocation of building materials, the cutting loss area (or cutting loss rate) of building materials is automatically calculated (step S125).

  When these processes are completed, the building material allocation image and the cutting loss area (or cutting loss rate) are displayed on the display unit 404 of the client device (step S126). The customer can see these displays and select whether or not to adopt this allocation method (step S127). If another allocation method is desired to be displayed, the process returns to step S123, and the reference line is set again. That is, the customer can display the allocation images of the first to third building material allocation methods described above, and determine which allocation method is to be applied based on a comparative study. Examples of screens that display the building material allocation image and the cutting loss area (or cutting loss rate) are shown in FIGS. In the figure, the thick vertical line represents the joint of the building material, and it can be seen that the appearance of the wall surface of the residential area depends on the position of the joint. The customer can determine which allocation method to use by looking at these screens and considering the appearance and the cutting loss area. Moreover, you may display together the cutting loss rate divided | segmented by the total area of the building material which uses the cutting loss area of a building material.

  In the examples shown in FIGS. 16 and 17, it is assumed that building materials are not reused, but loss area calculations when building materials are reused according to customer instructions are also included. May be performed. For example, in FIG. 16, the building material disposed on the left side of the upper opening portion generates 1.5 × 2 end materials, which can be assigned to the right side of the same opening portion. As a result, the loss of 1.5 × 4 places is not generated, and the loss area is reduced to three.

  When the customer adopts any of the allocation methods, the product information of the building materials to be used and the number of sheets used for each building material unit are displayed (step S128). An example of this display screen is shown in FIG.

  FIG. 19 is a flowchart showing details of the building material automatic assignment processing in step S124. The automatic building material assignment process acquires the dimensions of the outer wall surface of the house (horizontal length, vertical height, dimensions of each member such as the opening and end) from the construction image (step S191), Of these, the effective surface excluding the opening is recognized (step S192), and the building material is assigned to the effective surface in the predetermined allocation direction based on the set reference line (step S193). Specifically, it recognizes the effective surface for each assigned surface (height is 455mm and horizontal length is 2730mm at the maximum) divided by adjacent reference lines, determines its horizontal length, and determines its length. The process of allocating building material units according to is performed. In the present embodiment, a building material unit having a length of 9 × 1.5 width, a length of 6 × 1.5 width of a building material unit, and a length of 3 × 1.5 width of a building material unit are prepared.
