Description

Allocation device, program

The present invention relates to an allocation device and a program, and more particularly to an allocation device that supports an allocation work of building materials, and a program for causing a computer to function as the allocation device.

Conventionally, a technique has been proposed in which building materials are pasted on a design drawing of a house by construction simulation using data created by CAD (Computer Aided Design) (Reference 1 [Japanese Patent Publication No. 2005-242923]). reference). In Document 1, in a construction simulation, a region for pasting a building material is selected for a construction image displayed on the screen, and a building material to be pasted using a building material pasting tool is selected. Further, Document 1 describes a technique for estimating the amount of building material used for each building material by using information such as building material product name, price, and amount used.

By the way, in Reference 1, building materials are assigned to the construction image based on the dimensions of the building materials. That is, the building materials are allocated using the relationship between the shape and size of the object to which the building materials are pasted and the dimensions of the building materials. Therefore, there is a problem that the method of allocating building materials to the construction image is uniform.

This invention aims at providing the program for functioning the allocation apparatus which enabled selection of the allocation method of building materials, and a computer as this allocation apparatus.

The allocation apparatus of the form which concerns on this invention is about the 1st memory | storage part which stores the 1st data which represented the shape and dimension of the said target surface by making the construction surface which is the object of construction into a target surface, and several types of building materials A second storage unit storing second data representing a shape and dimensions, and a plurality of types applicable when attaching the plurality of types of building materials stored in the second storage unit to a construction surface An input for accepting designation information for designating a building material to be used from among the plurality of types of building materials stored in the third storage unit storing the allocation rules for each requirement and the second storage unit Allocation to the first data and the second data according to the requirements among the plurality of types of allocation rules when allocating the specified building materials to be used to the target surface By applying rules, A processing unit that generates an allocation diagram in which the building materials to be used are allocated to the target surface, and an output unit that outputs the allocation diagram generated by the processing unit, and the input unit receives and receives the requirements According to the requirement, an allocation rule to be applied to the target surface is specified from the plurality of types of allocation rules stored in the third storage unit.

The program according to the present invention causes a computer to function as an allocation device.

The allocation device described in the present embodiment will be described by taking as an example a case in which a building wall (wall material) is allocated to a wall surface, with an indoor wall surface in the building as a construction surface that is a target of construction. Hereinafter, a construction surface that is a target of construction is referred to as a “target surface”. However, the technology of the present embodiment is such that when building materials (wall materials) are assigned with the outer wall surface of the building as the target surface, building materials (floor materials) are assigned with the floor surface as the target surface, and building materials (ceilings) with the ceiling surface as the target surface. This can also be applied to the case of material allocation. The building material is assumed to be a plate-like member constituting the surface of the building. In addition, a plurality of building materials are used for one target surface, and it is allowed to cut on the site according to the shape of the target surface.

The building material is not necessarily a surface material. For example, if the building material is a wall material for indoor use, a cloth pasted on the surface of the wall material may become the surface material. In the following description, even when the wall material is not used as a surface material, the surface on the indoor side of the wall material is expressed as a surface forming a wall surface. Further, the target surface may be a virtually determined surface instead of the actual surface. For example, when a wall material such as a plaster board is attached to the frame material forming the base of the wall, a virtual plane on which the wall material is attached in the frame material becomes the target surface.

The same applies when the building material is a wall material, floor material, or ceiling material for the outer wall, but the floor material is often a surface material like flooring, and the wall material or ceiling material for the outer wall is In many cases, building materials also serve as surface materials. The flooring will be briefly described in the embodiment.

Furthermore, the building materials assumed in the following description are distinguished by a model number or a product number, and if they are the same model number or product number, they are formed in the same dimensions. Note that even if the model numbers are the same, there may be variations in the color and the like, but the product number is determined as one type including the color and the like. As the information for distinguishing the type of building material, either the model number or the product number may be used, but the model number is used below. The model number can be read as the product number.

The allocation device is configured using a computer. That is, a program for causing a computer to function as an allocation device is provided. The program may be provided in a state written in a ROM (Read （Only （Memory) in advance, but may be provided through an electric communication line such as the Internet for changing specifications and the like. Further, the program may be provided in a state where it is recorded on a computer-readable recording medium.

The building may be either newly built or already built. However, the shape and dimensions of the construction surface (that is, the surface on which the building material is attached) that is the object of construction are represented by data that can be read by a computer. Such data can be obtained as design data when a building is designed using CAD (Computer Aided Design) at the time of new construction. In the case of an existing building, the three-dimensional shape of the building is measured by a three-dimensional scanner using laser light, and the data of the shape and dimensions of the construction surface is generated from the measurement result data.

In addition, when measuring the shape and dimensions of the construction surface with a three-dimensional scanner, it is desirable to increase the resolution as much as possible (to reduce the interval between measurement points). The three-dimensional scanner is configured to measure the distance from the origin defined in the three-dimensional scanner to the construction surface, and is configured to measure the distance to the construction surface at a predetermined angular interval. That is, the three-dimensional scanner measures the distance to the construction surface at every predetermined angular interval, and the resolution of the three-dimensional scanner is determined by this angular interval. In other words, in the three-dimensional scanner, the distance is measured for each measurement point determined by the angular interval.

The resolution is expressed by using an interval between two measurement points at a certain distance (for example, 10 m) from the origin determined for the three-dimensional scanner. The measurement point may be said to be a point group virtually defined on a sphere centered on the origin, and the 3D scanner measures the distance on a straight line connecting the point group on the sphere and the origin. Will be.

By the way, when measuring the shape and dimensions of the construction surface with a three-dimensional scanner in a room with a large area, the position where the three-dimensional scanner is installed may be changed multiple times. When measuring the shape and dimensions of the construction surface, a lower limit is set for the density of measurement points on the construction surface in response to a request for measurement accuracy. Therefore, when the resolution is low, it is necessary to limit the distance from the three-dimensional scanner to the construction surface to a relatively short distance in order to keep the density of the measurement points on the construction surface above the lower limit value. Therefore, if the room has a large area, the number of measurements may increase.

On the other hand, if the resolution of the 3D scanner is high, the density of the measurement points on the construction surface can be kept above the lower limit value even if the distance from the 3D scanner is relatively large, so the resolution of the 3D scanner is high. It is possible to reduce the number of measurements. In general, when the resolution of a three-dimensional scanner is increased, the time required for one measurement becomes longer. However, as described above, the number of measurements is reduced as compared with the case where the resolution is low. Therefore, it is necessary to determine the resolution so that the entire measurement time is shortened according to the area of the room.

For example, assuming that a three-dimensional scanner capable of selecting a resolution is used and the first resolution is selected, one measurement time is 6 minutes, the number of measurements is 8, and the second resolution is When selected, it is assumed that one measurement time is 10 minutes and the number of measurements is two. If the time required for installing the three-dimensional scanner is ignored, if the first resolution is selected, the overall measurement time is 48 minutes, whereas if the second resolution is selected, the overall measurement time is 20 minutes. In such a case, by selecting the second resolution, the overall measurement time required to measure the shape and dimensions of the construction surface is shortened.

On the other hand, although it is a room with a small area, there is a part where a blind spot is generated from a three-dimensional scanner, and it is necessary to perform measurement twice regardless of whether the resolution is the first resolution or the second resolution. Assume a certain case. In this case, when the first resolution is selected, the overall measurement time is 12 minutes, and when the second resolution is selected, the overall measurement time is 20 minutes. Therefore, the overall measurement time is shorter when the first resolution is selected.

As described above, in order to shorten the overall measurement time as much as possible using a 3D scanner, the resolution of the 3D scanner may be selected according to the area of the room, the shape of the room, and the like. In other words, if the resolution of the three-dimensional scanner is selected according to the object to be measured, the overall measurement time can be shortened as much as possible.

Of course, the data of the shape and dimensions of the construction surface can be input manually, and it does not prevent the data from being generated even for the construction surface that is not the target of construction. However, since the technology for generating the shape and dimension data of the target surface is not the gist of the present embodiment, it will not be described in detail. That is, a case where data representing the shape and dimensions of the target surface is generated first will be described.

By the way, the indoor wall surface is often formed by a plurality of (for example, four) planes. Therefore, in order to assign a building material (wall material) that forms a wall surface, it is necessary to select which wall surface is to be formed. When selecting a wall surface to be formed, a plan view of the building is shown on the screen of a computer which is an allocation device. With respect to this plan view, a wall surface can be selected using an input device selected from a pointing device such as a mouse, a touch panel, a keyboard, and the like.

For example, when using a pointing device, the cursor (mark shown on the screen) is moved to the position of the desired wall surface displayed on the screen, and the corresponding wall surface is designated by clicking. A front view of the specified wall is displayed on the computer screen. Moreover, you may select the several wall surface adjacent to each other collectively. For example, if a cursor is placed on a plurality of wall surfaces and a click is performed in order while pressing the shift key on the keyboard, the plurality of wall surfaces are specified at once. When a plurality of wall surfaces are designated together, a development view of the selected wall surfaces is displayed on the computer screen.

Dimension is displayed on the front and development views. The display of dimensions follows a general dimensioning method. That is, the location where the dimension is displayed is shown for each target surface using the dimension extension line and the dimension line, and a numerical value representing the dimension is entered on the dimension line. Further, when the interval between the dimension extension lines is small and a numerical value cannot be entered on the dimension line, a lead line for entering the numerical value is drawn out from the dimension line. For example, when the target surface is rectangular, dimension extension lines and dimension lines are displayed so as to represent the dimensions of the four sides, and numerical values of the dimensions are shown on the four dimension lines, respectively.

When the target surface is a plurality of wall surfaces, the dimension of the vertical line segment passing through the center of the wall surface (that is, the height dimension at the center of the wall surface) is also shown in the development view. However, it is desirable to display the height dimension of the center of the wall outside the development view without using the dimension extension line. The line indicating the outline of the development view is displayed as a thicker line on the screen than the line for indicating the dimension. Further, in order to adjust the amount of data to be displayed on the screen, the development view is saved in both bitmap data (bmp) and vector data (dxf) formats. When displaying the development on the screen, one of bitmap data and vector data is selected as necessary.

In this way, when the target surface to which the wall material is to be attached is specified, the wall material is assigned to the target surface according to the type of wall material to be attached to the target surface, the constraints when attaching the wall material to the target surface, etc. It is done. When the calculation for allocating the wall material to the target surface is completed, an allocation diagram in which the building material is allocated to the target surface is displayed on the screen of the display device included in the computer. Further, the allocation diagram is not only displayed on the screen of the display device, but also can be printed by a printer.

Hereinafter, the allocation device 10 will be described in more detail. As shown in FIG. 1, the allocating device 10 includes a first storage unit 11 that stores first data that represents the shape and dimensions of the target surface, and a second that represents the shape and dimensions of a plurality of types of building materials. And a second storage unit 12 for storing data.

The first storage unit 11 actually stores the shapes and dimensions of a plurality of construction surfaces on which building materials need to be attached in a building. Therefore, the allocating device 10 includes the input device 31 for allowing the user to specify a target surface as a target to which a building material is allocated from among a plurality of construction surfaces. The input device 31 is selected from, for example, a pointing device such as a mouse or a touch pad, a keyboard, a touch panel provided on the display device screen, and the like. In the present embodiment, the output device 32 is a display device. Input information from the input device 31 is received by the input unit 15, and information is output from the output unit 16 to the output device 32. The 1st memory | storage part 11 may store together with the data of the construction surface in which the design drawing of the whole building needs to attach a building material. Moreover, it is desirable that the construction data is classified according to the type of building material to be applied.

For example, construction surfaces are classified into indoor wall surfaces, floor surfaces, ceiling surfaces, outer wall surfaces, and the like. Moreover, even if it is the same kind of construction surface, it is possible to attach a different building material. Therefore, rooms with different wall materials to be attached can be classified into different types of construction surfaces.

The allocation device 10 includes a processing unit 14 that processes data. The processing unit 14 displays a plan view on the screen of the output device 32 based on the building data stored in the first storage unit 11. Further, the processing unit 14 causes the user to designate the construction surface to be the target surface 20 through the input device 31 in a state where the plan view is displayed on the screen of the output device 32. When the user designates the target surface 20, the processing unit 14 displays a front view or a developed view of the target surface 20 on the screen of the output device 32 as illustrated in FIG. 2A. That is, if the target surface is one surface, a front view is displayed on the output device 32, and if the target surface is a plurality of adjacent surfaces, a development view developed on one plane is displayed on the output device 32. In the example shown in FIG. 2A, an opening 23 corresponding to an entrance / exit is formed on the target surface 20. When the allocation rules described below are applied to the target surface 20 shown in FIG. 2A, for example, used building materials 25, 26, 27, and 28 are allocated as shown in FIG. 2B. The used building material is a building material assigned to the target surface 20.

The shape of the outer periphery of the target surface 20 is generally rectangular, but a portion of the rectangle may be missing due to a step on the floor or ceiling. As the dimension of the outer peripheral edge of the target surface 20, the length dimension of each side is used. Moreover, when the opening part 23 equivalent to a window or an entrance / exit exists in the target surface 20, the position of the opening part 23 in the target surface 20 is shown. The position of the opening 23 is a distance from any side surrounding the target surface 20 to any side surrounding the opening 23, or a distance from any side surrounding the target surface 20 to the center of the opening 23. Is used. The size of the target surface 20 is known from the data stored in the first storage unit 11, and the position and size of the opening 23 are also known from the data stored in the first storage unit 11.

By the way, when the opening 23 corresponds to a window or an entrance / exit, the opening 23 corresponds to a wiring device, the opening 23 is formed for other purposes, etc. How to take is different.

For example, when the opening 23 is a window or an entrance / exit, a frame may be attached to the opening 23 as shown in FIG. The opening 23 in the example shown in FIG. 3 corresponds to a window. When the frame 24 is attached to the opening 23, the distance L1 from one edge of the target surface 20 to one edge of the opening 23, the Chile dimension L2 of the frame 24, the horizontal dimension L3 of the opening 23, and the vertical direction The inner dimension L4 is required. These data are included in the first data stored in the first storage unit 11. On the other hand, the frame 24 is not necessary for the opening 23 corresponding to the wiring device, but since a part of the wiring device (plate) overlaps around the opening 23, the size of the overlapping portion must be considered. .

The processing unit 14 extracts building materials that can be attached to the target surface 20 from the second storage unit 12 according to the type of the target surface 20 specified through the input device 31. That is, the 2nd memory | storage part 12 has memorize | stored the data table which matched the kind of building material with the kind of construction surface. When the target surface 20 is designated by the input device 31, the processing unit 14 extracts the building material corresponding to the type of the construction surface designated as the target surface 20 from the second storage unit 12, and outputs the extracted building material to the output device. 32 screens.

In this state, the input device 31 waits for an input for the user to select a building material. If the extracted building material is one type, the building material is designated as a used building material to be attached to the target surface 20 through the input device 31. If there are a plurality of types of extracted building materials, the building materials to be attached to the target surface 20 are selected through the input device 31, and the selected building materials are designated as the building materials to be used.

In the present embodiment, the building material used is a building material arranged to fill the target surface 20. The building materials include building materials with higher characteristics such as heat insulation performance or sound insulation performance than normal and normal building materials. The user operates the input device 31 according to the performance required for the target surface 20 and uses it. Select the type of building material.

In addition, it is desirable that the second storage unit 12 stores not only the model number of the building material that can be attached to the construction surface but also the description of the building material and the image of the building material. In this case, when the processing unit 14 displays the building material extracted from the second storage unit 12 on the screen of the output device 32, the processing unit 14 can refer to the building material or refer to the image, and the user determines the building material to be used. It is desirable to present helpful information.

The processing unit 14 performs a process of assigning the used building material to the target surface 20 when the target surface 20 is specified and the used building material attached to the target surface 20 is specified through the input device 31. The allocation device 10 includes a third storage unit 13 that stores an allocation rule that is a constraint condition when the building materials to be used are allocated to the target surface 20. The allocation rule means a group of rules applied when the building materials to be used are allocated to the target surface 20.

The allocation rule is set so as to fill the target surface 20 by arranging the used building materials in order on the target surface 20. The basic allocation rules for allocating building materials to be used for the target surface 20 are as follows: the position at which the building material to be used is first attached to the target surface 20, the direction in which the building material is arranged on the target surface 20 from the initial position, and the building material to be used And the orientation to be arranged. The basic allocation rule is to use the target surface 20 after arranging the used building material for the target surface 20 for the first time, arranging the used building materials in order in the direction indicated in the allocation rule. It is created to be filled with building materials. The building materials to be used are allocated to the target surface 20 according to such an allocation rule.

The allocation rule may be determined so that the orientation of the building material used with respect to the target surface 20 does not change. In addition, the allocation rule arranges the main used building materials among a plurality of types of used building materials at the target position, and then arranges the subordinate used building materials so as to fill the gap formed on the target surface 20. It may be determined to do. These allocation rules are examples, and various allocation rules are determined according to the shape of the target surface 20, the type of building materials used, and the like. Below, the example of an allocation rule is demonstrated.

Figure 4 shows an example of allocation rules. In the example shown in FIG. 4, after the precondition is selected (S11), it is determined whether or not the opening 23 exists in the target surface 20 (S12). As the precondition, the structure of the building and the type of the target surface 20 can be selected.

Here, the case where the structure of the building is selected from wooden or RC (Reinforced-Concrete) is taken as an example. The reason why the building structure is selected as a precondition is that the type of frame to which the building material is attached differs depending on the structure of the building.

The type of the target surface 20 is the type of the surface constituting the room. That is, the type of the target surface 20 includes a wall surface, a floor surface, a ceiling surface, and the like. Since the target surface 20 is a surface that constitutes a room and on which used building materials are arranged, depending on the shape of the room, there is also a surface that is not classified into any of a wall surface, a floor surface, and a ceiling surface.

For example, in a building such as RC structure, a part covering the beam may be exposed indoors, and the building material used may be arranged on the surface of the part covering the beam (hereinafter referred to as “covered surface”). When the portion covering the beam is exposed indoors, the portion covering the beam protrudes indoors from the ceiling surface. Furthermore, the part which covers a beam may protrude from the upper part of a wall surface to the indoor side. In this case, the portion covering the beam protrudes indoors from the corner portion sandwiched between the wall surface and the ceiling surface. Since used building materials may be arranged on the covering surface, it is desirable that the covering surface can be selected as the target surface 20 as well as the wall surface, floor surface, and ceiling surface.

By the way, when a building is made of wood and the target surface 20 is a wall surface, the used building materials are arranged such that the longitudinal direction is along the horizontal direction, and the building materials are arranged so that the longitudinal direction is along the horizontal direction. There is a case. That is, when the building is made of wood, the used building materials to be arranged on the wall surface are often arranged so that the longitudinal directions of the used building materials are aligned in the same direction.

When the building is an RC structure and the used building materials are arranged on the covering surface, the used building materials 29 are arranged so that the longitudinal direction is along the horizontal direction as shown in FIG. 5A. The example shown in FIG. 5A is used on the surface of the portion 55 covering the beam in a building in which the portion 55 covering the beam protrudes from the corner portion sandwiched between the wall surface 50 and the ceiling surface 52 as shown in FIG. 5B. The state which has arrange | positioned the building material 29 is shown. Thus, when the target surface 20 is a covering surface and the surface of the covering surface is covered with the building material used, the building material 29 used is arranged so that the longitudinal direction is along the horizontal direction. Even if the building is an RC structure, the building materials 25, 26, 28, etc. used are arranged in addition to the covering surface.

In the above-described example, the covering surface is handled as a wall surface, a floor surface, and a ceiling surface, but may be handled as a part of the wall surface 50 or the ceiling surface 52. That is, the processing unit 14 may be configured such that when the wall surface 50 or the ceiling surface 52 is selected as the target surface 20, the covering surface can be specified as a part of the wall surface 50 or the ceiling surface 52. .

When the target surface 20 selected as the precondition is a ceiling surface, for example, it is specified whether a ceiling panel exists or does not exist. This is because the type of building material and the type of accessories described later differ depending on the type of ceiling surface. In addition, when the target surface 20 is a floor surface, for example, it is specified whether or not floor heating is performed. Further, when floor heating is performed, the type of floor material integrated type and floor material separation type is specified. .

In the following, it is assumed that a wooden structure is selected as the building and a wall surface is selected as the target surface 20 in step S11 of FIG. If it is determined that the opening 23 is present in step S12 under this precondition (S12: yes), the processing unit 14 arranges the building materials to be used in the left region of the opening 23 located on the leftmost side in the target surface 20. The building materials to be used are allocated as described above (S13). Next, the processing unit 14 allocates the used building material so as to arrange the used building material in the region on the right side of the opening 23 (S14). Thereafter, the processing unit 14 arranges the used building material in the left area of the opening 23 adjacent to the right of the opening 23 described above (S15), and uses the building material in the right area of the opening 23. Building materials are allocated (S16). Here, the processing unit 14 assigns the used building materials to each region so that the used building materials are arranged in order from the left side. That is, the process of step S <b> 13 corresponds to arranging used building materials from the left end of the target surface 20. In step S15, since the same area as step S14 is targeted, it can be usually omitted. However, the building material used may not reach the opening 23 on the right side only by the process of step S14. In order to allocate the building materials to be used with certainty, the process of step S15 is provided.

The processing of step S15 and step S16 is continued until the processing for all the openings 23 of the target surface 20 is completed (S17). That is, when the building materials to be used are arranged in the region on the right side of the opening 23 and the region in which the building materials are arranged reaches the right end of the target surface 20 (S17: yes), the processing for allocating the building materials to be used is completed.

Here, the target surface 20 is a wall surface, and the opening 23 is assumed to be a window or an entrance. In addition, the building materials used are attached such that the longitudinal direction thereof is along the vertical direction, and the longitudinal dimensions of the building materials used disposed on the right or left with respect to the opening 23 are larger than the vertical dimensions of the target surface 20. Assumes a short case. Therefore, the target surface 20 cannot be filled only with the used building materials allocated by the processing from step S13 to step S17 described above. Therefore, appropriate used building materials are also disposed in the remaining portion of the target surface 20.

The processing from step S13 to step S17 is repeated until the used building material is allocated to the entire surface of the target surface 20 (S18: no), and when the used building material is allocated to the entire surface of the target surface 20 (S18: yes), the target surface The work of allocating building materials to be used at 20 is finished. In addition, when the opening part 23 does not exist in the target surface 20 (S12: no), the process part 14 arranges use building materials in order toward the right (arrangement direction) from the left end (initial position) of the target surface 20 (S19). ). When the used building materials are arranged on the target surface 20 and filled with the used building materials up to the right end of the target surface 20 (S20: yes), the processing unit 14 ends the process of assigning the used building materials to the target surface 20.

4 assumes that the target surface 20 is a wall surface, but part of the allocation rule is changed depending on the type of the target surface 20 selected as a precondition in step S11. That is, since the types of the target surface 20 that can be selected include a ceiling surface, a floor surface, a covering surface, and the like in addition to the wall surface, the processing unit 14 assigns according to the type of the target surface 20 selected in step S11. Use rules.

By the way, the dimensions of building materials are standardized sizes (standard size), and in particular, the dimensions in the longitudinal direction are often selected from a plurality of types of fixed dimensions. Usually, the maximum fixed dimension in the longitudinal direction of the building material (hereinafter referred to as “maximum fixed dimension”) is 2700 mm. On the other hand, when the building material to be used is assigned to the target surface 20, the dimension in the specific direction of the target surface 20 is not necessarily equal to or less than the fixed dimension in the longitudinal direction of the building material in use. When the dimension of the target surface 20 in the specific direction exceeds the fixed dimension in the longitudinal direction of the building material used, and when the building material to be used is arranged so that the longitudinal direction of the building material used is along the specific direction, a plurality of usages are used. It is necessary to arrange building materials in the longitudinal direction.

For example, if the height from the floor surface to the ceiling surface exceeds 3000 mm, even if the building materials used are arranged so that the longitudinal direction of the building materials to be assigned to the wall surface is along the vertical direction of the wall surface, the floor surface and the ceiling surface Cannot be filled with a single building material. Therefore, it is necessary not only to arrange a plurality of used building materials in the width direction but also to arrange a plurality of used building materials in the longitudinal direction.

Fig. 6 shows an example in which the building materials used are assigned to the wall surface in the state described above. In the example shown in FIG. 6, the dimension between the floor surface 51 and the ceiling surface 52 exceeds the maximum fixed size of the building materials used 531, 532, 533, 534, and 535, and the building materials used 531, 532, 533, 534, A case where the size is smaller than twice the maximum fixed size of 535 is assumed. In the example shown in FIG. 6, the wall surface has the opening 23, and the dimension from the lower edge of the opening 23 to the floor surface 51 and the dimension from the upper edge of the opening 23 to the ceiling surface 52 are each one. It is assumed that it is below the fixed dimension in the longitudinal direction of the used building materials 533, 534, and 535. In the following description, the used building materials 531, 532, 533, 534, and 535 are referred to as used building materials 53 when they are not distinguished.

Among the wall surfaces, in the region D1 excluding the space between the opening 23, the lower edge of the opening 23 and the floor surface 51, and the space between the upper edge of the opening 23 and the ceiling surface 52, two walls are provided in the vertical direction of the wall surface. Used building materials 531 and 532 are arranged, and a plurality of used building materials 531 and 532 are arranged in the horizontal direction of the wall surface. The longitudinal direction of the used building materials 531 and 532 is along the vertical direction of the wall surface, and the width direction of the used building materials 531 and 532 is along the horizontal direction of the wall surface. In the region D1, the plurality of building materials 531 and 532 adjacent in the width direction are arranged in a straight line with one end edge (that is, the upper edge or the lower edge) in the longitudinal direction along the horizontal direction of the wall surface.

Hereinafter, the state where the used building materials 531 and 532 are arranged as in the region D1 is referred to as step bonding. The step bonding is premised on an arrangement in which a plurality of used building materials 53 are arranged in the longitudinal direction in the vertical direction of the target surface 20. The step pasting is a state in which a plurality of used building materials 53 are arranged in the width direction in the horizontal direction of the target surface 20, and one end edge in the longitudinal direction of the plurality of used building materials 53 arranged in the width direction is on a straight line in the horizontal direction. It is in a state of side-by-side arrangement. The case where the number of building materials 53 used in the longitudinal direction is two is referred to as two-step pasting. In addition, the building where step sticking is adopted is often other than a house, and the target surface 20 where step sticking is adopted is only a wall surface.

Incidentally, it is necessary to divide the wall surface into the area D1 where the opening 23 does not exist and the area D2 where the opening 23 exists regardless of whether or not the step pasting is adopted. The region D2 where the opening 23 exists is a region of the opening 23 in the wall surface, a region between the lower edge of the opening 23 and the floor surface 51, and between the upper edge of the opening 23 and the ceiling surface 52. It means the range that combines the areas. That is, when it is assumed that the opening 23 is expanded downward to the floor surface 51 and the opening 23 is expanded upward to the ceiling surface 52, the area occupied by the expanded opening 23 is the opening 23. It is assumed that the area D2 exists. The region D1 in which the opening 23 does not exist means a region of the wall surface excluding the region D2 in which the opening 23 exists.

The reason for dividing the wall surface into a region D1 where the opening 23 does not exist and a region D2 where the opening 23 exists is that the region D1 where the opening 23 does not exist and the region D2 where the opening 23 exists have different dimensions. This is because the building material 53 used is necessary. In particular, when step bonding is performed on at least a part of the wall surface, as shown in FIG. 6, the dimension in the longitudinal direction differs between the region D1 where the opening 23 does not exist and the region D2 where the opening 23 exists. A plurality of types of building materials 53 may be required.

As a rule, the allocation rule in the case of step bonding is adopted when the dimension between the floor surface 51 and the ceiling surface 52 is larger than the maximum fixed dimension in the longitudinal direction of the building material 53 used. Therefore, in the step-by-step allocation rule, after the wall surface is divided into the regions D1 and D2, the building material used (the building material 531 used in FIG. 6) whose longitudinal dimension is the maximum fixed size is arranged on the wall surface in the region D1. It has established. Further, in the step pasting allocation rule, when a plurality of used building materials (used building materials 531 and 532 in FIG. 6) are arranged in the vertical direction, the used building material (used building material 531 in FIG. 6) having a large longitudinal dimension is lower. The arrangement of a plurality of building materials to be used is determined.

However, when there are building materials in use with vacuum heat insulating materials, the allocation rules stipulate that priority is given to the placement of building materials in use with vacuum heat insulating materials. In other words, after the position of the vacuum heat insulating material is preferentially determined and the building material with the vacuum heat insulating material is assigned to the wall surface, the remaining space is filled so that the gap generated between this building material and the floor or ceiling surface is filled. Building materials used are allocated. FIG. 7 is an example in which used building materials 541 and 542 having a vacuum heat insulating material are arranged, and in the region D1 where the opening 23 does not exist and the region D2 where the opening 23 exists, near the middle in the vertical direction of the wall surface. The building materials 541 and 542 used are allocated so that the vacuum heat insulating material is located at the top.

In the example shown in FIG. 7, in order to ensure the function of heat insulation, the building materials 541 and 542 provided with a vacuum heat insulating material are preferentially arranged in the middle portion in the vertical direction of the wall surface. In other words, the position of the vacuum heat insulating material is designed so as to satisfy the heat insulating performance, and the positions of the building materials 541 and 542 provided with the vacuum heat insulating material are determined so that the vacuum heat insulating material is positioned at the designed position. The allocation rule in this case stipulates that normal building materials 543, 544, 545, and 546 are allocated to areas of the wall surface that are not filled with only the building materials 541 and 542 that include the vacuum heat insulating material.

The above-described allocation rule defines basic processing of the processing unit 14. However, it is desirable that the allocation rules can be selected from a plurality of types according to requirements such as performance, cost, workability, and design even if the target surface 20 is the same and the building materials used are the same type. That is, an allocation rule is defined for each requirement. The kind of building material recommended as a building material to be used may be changed according to these requirements. That is, when extracting the building material to be attached to the target surface 20 from the second storage unit 12, the processing unit 14 extracts a building material that meets the requirement if the requirement has been input first through the input device 31. It is possible. Further, when the user inputs a requirement after specifying the building material to be used using the input device 31, the processing unit 14 matches the building material specified as the building material to be used with the requirement after the requirement is input. You may change to building materials.

In the following description, it is assumed that requirements are entered after the target surface 20 and building materials to be used are specified. In this embodiment, the requirements are selected from five types: standard, performance priority, cost priority, workability priority, and design priority.

The performance priority is further classified into heat insulation performance, sound insulation performance, etc., and one or more types of performance classification can be designated through the input device 31. When the performance priority is selected, an allocation rule that determines the type and orientation of the building material to be used attached to the target surface 20 is applied so as to enhance the performance of the designated section.

In cost priority, as described later, when there are high-performance building materials and building materials to fill gaps, the number of high-performance building materials should be the same as the standard, and the total number of building materials should be minimized An allocation rule that includes In other words, when the cost priority allocation rule is adopted, the number of building materials to be used is reduced as compared with the case of applying the standard allocation rule, which leads to cost reduction.

In the workability priority, in the work of attaching the used building material to the target surface 20, an allocation rule including a restriction condition of minimizing the measurement work of the position where the building material is attached and the processing work of the used building material is minimized. Design priority is selected mainly when the building material used is a surface material, and the allocation rules regarding the finished appearance such as the direction in which the building material to be used is attached to the target surface 20 and the position at which the building material is attached are defined.

By the way, there are cases where specified building materials are prohibited from cutting or drilling. For example, when the building material uses a vacuum heat insulating material, if the vacuum heat insulating material is cut or a hole is made in the vacuum heat insulating material, the vacuum state cannot be maintained, so the heat insulating effect cannot be obtained. . On the other hand, an opening 23 may be formed on the target surface 20, and if this type of building material is allocated around the opening 23, it cannot be constructed. Therefore, the processing unit 14 can be replaced with this type of building material and can be replaced with a building material that can be cut or drilled so that building materials that cannot be cut or drilled are not applied around the opening 23. Has been.

Therefore, an appropriate building material is selected as a building material to be used so that a building material that cannot be cut or punched is not allocated around the opening 23. In addition, as for the building material using a vacuum heat insulating material, the area | region which does not provide the vacuum heat insulating material is provided, for example by 20 cm in the both ends of a longitudinal direction. This region can be cut or punched, and if this region is used, the size or shape can be adjusted while maintaining a function such as heat insulation.

FIG. 8 shows an example of the finish due to the difference in requirements in association with the schematic diagram. The target surface 20 is not a rectangle but a shape in which the lower left corner of the rectangle is missing, and one type or two types of building materials are used. The hatched building material (hereinafter referred to as the first building material) 21 is a highly functional building material having high heat insulation performance and sound insulation performance, and the building material (hereinafter referred to as the second building material) 22 without hatching is the first It is a building material arranged in a gap generated when the building materials 21 are arranged. That is, it is assumed that the first building material 21 is more expensive than the second building material 22. The first building material 21 can be cut at both ends in the longitudinal direction so that the length can be adjusted on site. Moreover, the 2nd building material 22 can be cut | disconnected in arbitrary positions.

In the following description, it is assumed that the first building material 21 and the second building material 22 have the same dimensions before cutting. Since many building materials are formed with standardized standard dimensions, this assumption is valid.

The first building material 21 has a total length of about 1800 mm, leaves about 200 mm at both ends in the longitudinal direction, and improves the heat insulation performance and sound insulation performance within the range of about 1400 mm in the center (hereinafter referred to as functional members). The structure in which the "calling" is arranged is known. The building material having this configuration cannot cut the center part, but can cut about 150 mm at both ends in the longitudinal direction. In other words, the length of the first building material 21 can be shortened by about 300 mm at the maximum.

8, the standard allocation rule includes a rule that the center line along the horizontal direction of the target surface passes through the vicinity of the center of the functional member in the first building material 21. That is, the standard allocation rule includes a rule that the first building material 21 is arranged such that the longitudinal direction of the first building material 21 is along the vertical direction of the target surface. Moreover, when the dimension in the longitudinal direction of the first building material 21 is smaller than the dimension in the vertical direction of the target surface, the rule is to fill the missing dimension with a member obtained by cutting the second building material 22 into a necessary dimension. Is set. Furthermore, in the standard allocation rule, the second building material 22 arranged in the longitudinal direction of the first building material 21 is required to have the same length. When such an allocation rule is applied, the first building material 21 and the second building material 22 are allocated as illustrated by standard items in FIG.

In FIG. 8, the performance priority allocation rule includes a rule that the area of the first building material 21 occupying the target surface is maximized. Therefore, the usage amount of the second building material 22 is minimized. The cost priority allocation rule includes a rule of minimizing the total number of first building materials 21 and second building materials 22 as described above. Moreover, it is desirable to set a rule that adds a restriction that the number of the first building materials 21 having high functions is not changed in the cost priority allocation rule. Without this rule, in order to reduce costs, an option of increasing the number of the second building materials 22 occurs, and the heat insulation performance and the sound insulation performance are significantly lowered from the standard.

The workability priority allocation rules include a rule that minimizes the number of times the building material is processed and a rule that only cuts straight lines. In other words, in the construction priority assignment rule, the direction in which the building material is attached to the target surface 20 is limited in that the longitudinal direction of the building material is either the vertical direction or the horizontal direction of the target surface 20, but the vertical direction and the horizontal direction There is no limit to one of the directions. In short, the direction in which the building material is arranged is determined so that the number of times of cutting the building material is reduced. In addition, when the allocation rule with priority on workability is adopted, the cut surface becomes one flat surface, and a plurality of flat surfaces are not formed on one cut surface. It becomes easy.

Design priority layout rules are applied mainly when the target surface is an indoor floor surface or when the target surface is a building material (brick, tile, etc.) on the outer wall of the building. As the design priority assignment rule, for example, a rule is set so as to repeat a predetermined arrangement pattern.

Such an allocation rule is desirably displayed on the screen of the output device 32 together with the outline diagram in the format as shown in FIG. 8 after the target surface 20 is designated. In this state, it is desirable that the user selects a desired allocation rule using the input device 31. If the user selects an allocation rule, it is determined whether the building material used will be one type or multiple types. Thereafter, similar to the above-described operation, building material candidates that can be attached to the target surface 20 are displayed on the output device 32.

As described above, the target surface 20 and the building material are specified, and the allocation rule to be applied is determined. Thereafter, the processing unit 14 applies the allocation rule to the data stored in the first storage unit 11 and the data stored in the second storage unit 12 to allocate the building materials to be used to the target surface 20. The processing unit 14 generates an allocation diagram in which the building materials to be used are allocated to the target surface 20, and outputs the allocation diagram through the output unit 16. An example of an allocation diagram is shown in FIG. The target surface 20 shown in FIG. 9 is formed in a rectangular shape with the lower left corner missing. Such a shape is formed on the wall surface when it corresponds to a step on the floor surface.

The allocation diagram shown in FIG. 9 is generated by applying a standard allocation rule. For the target surface 20, 13 first building materials 21 and 7 second building materials 22 are used. Specifically, among the building materials arranged in the center in the vertical direction in FIG. 9 and arranged in the left-right direction, the first and seventh from the right are the second building materials 22, and the remaining 13 pieces are the first. It is a building material 21. Further, the short building material 22a of the upper stage and the lower stage of FIG. 9 is generated by cutting so as to divide the second building material 22. When one of the second building materials 22 is divided, it is possible to generate five building materials 22a in consideration of the loss at the time of cutting. Since the number of building materials 22a is 22, the building material 22a can be generated from the five second building materials 22, and together with the two second building materials 22 used in the central portion in the vertical direction, Two building materials 22 are used.

When the standard allocation rule is applied to the target surface 20 shown in FIG. 9, as described above, the building material is embedded so as to fill the target surface 20 with the 13 first building materials 21 and the 7 second building materials 22. Can be assigned. If the building material is allocated to the same target surface 20 without considering the division of the second building material 22, 24 (22 + 2) second building materials 22 are required, resulting in significant waste. become. In this embodiment, since the allocation device 10 configured by a computer allocates the building material to the target surface 20 in consideration of the division of the building material, it is possible to estimate in the same manner as when a person allocates the building material, and the building material is wasted. Order can be prevented.

Furthermore, since the allocation rules can be selected from a plurality of types, building materials can be allocated to the target surface 20 according to the purpose desired by the user, and the satisfaction of the user can be increased. In particular, as shown in FIG. 8, if the assignment device 10 displays an example of the finish according to the assignment rule on the screen of the output device 32, the user can imagine the finished state by the screen of the output device 32. Can do. Therefore, when used for proposals to customers, the appeal effect can be enhanced. In this case, the target surface 20 displayed on the screen of the output device 32 is more preferably the target surface 20 in the actual building that is the construction target.

When the processing unit 14 generates an allocation diagram as shown in FIG. 9, the processing unit 14 can determine the type and quantity of building materials (used building materials) necessary for the target surface 20. The output unit 16 outputs the type and quantity of the building material used determined by the processing unit 14 in the form of a material table in which the type and quantity are associated with each other. That is, the allocating device 10 not only automatically generates an allocation diagram, but also automatically generates a material table showing the types and quantities of necessary building materials. The output destination of the material table is based on the output device 32. The output unit 16 is configured to output the material table to the printer after the material table is confirmed by the output device 32.

Incidentally, in order to attach the building material to be used to the target surface 20, a member such as a screw or a material such as an adhesive is required, and a member for decorating the building material such as a peripheral edge may be required. Below, the material required when attaching a building material to be used to the target surface 20 is called an accessory. The quantity of accessories varies depending on the quantity of building materials used. Therefore, the 3rd memory | storage part 13 has memorize | stored not only an allocation rule but the structure rule which matched the kind and quantity of the accessory used in order to attach a building material to a construction surface with the unit quantity of building materials. When the processing unit 14 determines the quantity of building materials to be used and generates an allocation diagram, the processing unit 14 determines the type and quantity of accessories using the configuration rule. The output unit 16 preferably outputs a material table obtained by adding the type and quantity of accessories obtained by the processing unit 14 to the above-described material table.

Furthermore, it is desirable that the second storage unit 12 stores the unit price of building materials, and the third storage unit 13 stores the unit price of accessories. Since the processing unit 14 can calculate the total amount (cost) of the building materials and accessories allocated to the target surface 20 using the unit price information of the building materials and accessories, the unit price and the amount are indicated on the material table. Thus, it is possible to automatically create an estimate. Furthermore, it is desirable for the processing unit 14 to obtain the dimensions and weight when the building materials and accessories used are loaded. When the required loading dimensions and weight are described in the bill of materials, it can be used for inventory management or transportation management.

Incidentally, as in the building 40 shown in the plan view of FIG. 10, a part of the room 41 may be formed to protrude from one outer wall 42 surrounding the building 40. Such a room 41 includes a part in which two of the four walls 431, 432, 433, and 434 surrounding the room 41 divide the external space and the internal space of the building 40, and the building 40. And a part for partitioning the interior space. Of the remaining two walls 431 and 434 surrounding the room 41, one wall 431 as a whole partitions the external space and internal space of the building 40, and the other wall 434 as a whole divides the internal space of the building 40. Partitioning.

Suppose a building material is assigned to the target surface 20 including the walls 432 and 433 in such a room 41. In this case, it is necessary to allocate to the walls 432 and 433 a mixture of building materials that are applied to the part that partitions the external space and the internal space of the building 40 and building materials that are applied to the part that partitions the internal space of the building 40. Become.

The allocation device 10 has a function of dividing the designated target surface 20 into a plurality of sections in order to deal with such cases. That is, the input device 31 can perform an operation of dividing the image of the target surface 20 displayed on the output device 32 into a plurality of sections, and outputs division information when the operation of dividing the target surface 20 is performed. . Moreover, the input part 15 of the allocation apparatus 10 is comprised so that the designation | designated information which designates a building material to be used for every division may be received, if division information is received from the input device 31. FIG. Further, when the input unit 15 receives the division information, the processing unit 14 applies the allocation rule for each divided section. That is, when the input unit 15 receives the division information, the assignment device 10 does not treat the target surface 20 as a single surface but treats it as if there are a plurality of target surfaces 20.

Therefore, for the building 40 having a shape as shown in FIG. 10, a building material including a heat insulating material is used for a part of the walls 432 and 433 adjacent to the wall 431, and a heat insulating material is used for the remaining parts of the walls 432 and 433. It is possible to specify to use building materials that are not equipped with.

The allocation device 10 of the present embodiment described above includes a first storage unit 11, a second storage unit 12, a third storage unit 13, a processing unit 14, an input unit 15, and an output unit 16. The 1st memory | storage part 11 stores the 1st data showing the shape and dimension of the target surface 20 by making the construction surface which is the object of construction into the target surface 20. FIG. The 2nd memory | storage part 12 has memorize | stored the 2nd data showing the shape and dimension about multiple types of building materials. The 3rd memory | storage part 13 has memorize | stored the multiple types of allocation rule applicable when attaching a multiple types of building material to a construction surface for every requirement. The input unit 15 receives designation information for designating a building material to be used from a plurality of types of building materials stored in the second storage unit 12. When the processing unit 14 allocates the designated building materials to the target surface 20, the allocation rule specified according to the requirement among the multiple types of allocation rules is applied to the first data and the second data. By doing so, the allocation figure which allocated the used building material to the object surface 20 is produced | generated. The output unit 16 outputs the allocation diagram generated by the processing unit 14. Furthermore, the input unit 15 receives the requirement, and according to the received requirement, the allocation rule to be applied to the target surface 20 is specified from the plurality of types of allocation rules stored in the third storage unit 13. It is configured.

According to this configuration, since the assignment work of the building materials to be used on the target surface 20 is automated by the assignment device 10, an assignment work that requires about 3 hours per case, for example, takes about 20 minutes per case, for example. Shortened to That is, the number of man-hours required for the allocation work is reduced by, for example, about 90%, resulting in a significant man-hour reduction.

The multiple types of allocation rules are set so that the used building materials are sequentially arranged and attached to the target surface 20, and include a position where the used building materials are first attached to the target surface 20 and a direction in which the used building materials are arranged in order on the target surface 20. It is out.

According to this configuration, the used building material is automatically allocated to the target surface 20 by a simple operation of simply designating the target surface 20 and the used building material in the allocation work. Moreover, since the allocation rules are set so that the target surface 20 is filled with the used building materials by arranging the used building materials in order on the target surface 20, the allocation device 10 can perform the allocation work by iterative processing, The amount of description is reduced. Moreover, since the allocation apparatus 10 does not require complicated calculation, an increase in processing load is suppressed.

Furthermore, there are a plurality of types of allocation rules, and it is desirable that the third storage unit 13 stores the allocation rules for each requirement. In this case, it is desirable that the input unit 15 is configured such that an allocation rule to be applied to the target surface 20 is specified from the allocation rules stored in the third storage unit 13 according to the requirements.

According to this configuration, according to the purpose of allocating building materials to the target surface 20, it is possible to specify allocation rules according to requirements from a plurality of types of allocation rules. Can be allocated appropriately.

When the processing unit 14 assigns the designated building materials to the target surface 20, by applying the allocation rule specified according to the requirements to the first data and the second data, It is desirable to be configured to determine the quantity of building materials to be used. In this case, it is desirable that the output unit 16 is configured to output a material table that represents the type and quantity of building materials used by the processing unit 14.

According to this configuration, when building materials are assigned to the target surface 20, the type and quantity of building materials to be used are required, so that it is easy to order building materials. In particular, since the bill of material is output, if the bill of material is created in a format suitable for ordering, the material bill can be used for ordering work, leading to labor saving.

It is desirable that the third storage unit 13 stores a configuration rule in which the types and quantities of accessories used for attaching a plurality of types of building materials to the construction surface are associated with the plurality of types of building materials. In this configuration, when the processing unit 14 determines the quantity of building materials to be used, it is desirable to determine the types and quantities of accessories used to attach the building materials to be used to the target surface 20 by using the quantities and the configuration rules. . The output unit 16 is preferably configured to include the type and quantity of the accessory obtained by the processing unit 14 in the material table.

According to this configuration, not only the type and quantity of building materials, but also a material table including accessories necessary for attaching the building materials to the target surface 20, that is, screws, adhesives, decoration materials, and the like are created. Therefore, it is possible to prevent forgetting to order accessories as well as to save labor in ordering work. In addition, since it is possible to know the area, volume, weight, etc. necessary for storage of building materials and accessories, it is possible to secure inventory space and arrange transportation vehicles. In addition, if the information on the unit price of building materials and accessories is available, the total price can be estimated from the unit price and quantity.

The multiple types of allocation rules are set to allow cutting of building materials when any of the multiple types of building materials is attached to the construction surface. When the used building material to be allocated to the target surface 20 is a building material that is allowed to be cut by the allocation rule, the processing unit 14 allocates the remaining portion of the used building material generated by the cutting to the target surface 20 and then determines the quantity of the used building material. It is desirable to decide.

According to this configuration, when a building material that can be cut is allocated to the target surface 20, the remaining portion obtained by cutting the used building material is also used, as in the case where a person estimates the number of building materials to be attached to the target surface 20. The quantity of building materials to be optimized can be optimized. In other words, the accuracy of estimating the quantity of building materials is increased, and the possibility of ordering building materials wastefully is reduced.

The processing unit 14 can replace the used member with the building material that can be used and cut from the building material stored in the second storage unit 12. In the replacement of building materials, there is a portion where cutting is prohibited in the used building material designated by the designation information received by the input unit 15, the opening 23 is formed in the target surface 20, and the building material used is changed to the opening 23. This is done when it is necessary to cut building materials to be installed.

For example, if it is necessary to cut (including drilling) the building material used to be attached to the target surface 20 to accommodate the opening 23, a vacuum heat insulating material cannot be used for the building material used. That is, when the vacuum heat insulating material is cut (including a case where a hole is made), the heat insulating effect cannot be obtained, so this kind of building material cannot be cut. For this reason, this kind of building material is not used as a used building material in a place that requires cutting, and a building material that is allowed to be cut is used as a used building material. In addition, since the building material using a vacuum heat insulating material has the area | region which has not arrange | positioned the vacuum heat insulating material in the both ends in a longitudinal direction, if it is this area | region, it can be cut | disconnected (a hole is included). is there.

It is desirable that the input unit 15 is configured to receive division information for dividing the target surface 20 into a plurality of sections, and to receive designation information that specifies building materials to be used for each section when the division information is received. In this configuration, the processing unit 14 receives requirements for each partition, and applies an allocation rule corresponding to the requirements received for the partition among a plurality of types of allocation rules for each partition.

According to this structure, when the division which requires the building material containing a heat insulating material and the division which does not require the building material containing a heat insulating material exist in one target surface 20, the target surface 20 is made into several divisions. It can be divided and appropriate building materials can be assigned to each section. In general, since building materials including heat insulating materials are more expensive than building materials not including heat insulating materials, by assigning building materials for each section of the target surface 20, compared to the case where only building materials including heat insulating materials are attached, the cost is reduced. It is possible to suppress the increase in

The above-described allocation device 10 can be realized by executing a program on a personal computer, but the basic configuration of the allocation device 10 may be realized by a server device or a cloud computing system. In this case, a terminal device (personal computer, smartphone, tablet terminal, or the like) serving as a client may be used as the input device 31 and the output device 32.

The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it can be changed.
