Mode for Carrying Out the Invention

[0017] <First Embodiment> [Example of the attachment mode of the eaves gutter] Hereinafter, the design and construction support device of this embodiment will be described. When attaching the eaves gutter that constitutes the rain gutter to a building, a support fitting such as a metal fitting is used. The support fitting is provided so as to be fixed to a predetermined part on the building side while supporting the eaves gutter.

[0018] In the following description, the building to which the eaves gutter is attached may also be described as the "building to be constructed", and the eaves gutter to be attached to the building to be constructed may also be described as the "eaves gutter to be constructed".

[0019] First, with reference to FIG. 1, an example of the attachment mode of the eaves gutter corresponding to the design and construction support device of this embodiment will be described. In this figure, an example is shown in which two systems of eaves gutters 20 (10 - A, 20 - B) are connected to the drop - opening 10 (vertical gutter). Each of the eaves gutters 20 - A and 20 - B is supported by a support fitting 30 so as to be given a predetermined gradient. In the example of this figure, the support fitting 30 is fixed to the gable part of the folded - plate roof 40. In this case, the interval (support interval p) for positioning the support fitting 30 in the longitudinal direction of the eaves gutter 20 is the interval between adjacent gable parts of the folded - plate roof 40. In the following description, the case where the eaves gutter 20 is attached by the support fitting 30 according to the mode of FIG. 1 will be taken as an example.

[0020] [Regarding the construction support function] The design and construction support device of this embodiment is used, for example, in the design stage or construction stage of a building. In response to an operation in which a user inputs numerical values of predetermined parameters (an example of calculation use information), information (support tool-related information) calculated and determined regarding the support tool used for attaching the eaves of the construction target can be presented to the user.

[0021] The design and construction support device of this embodiment may be, for example, a personal computer, a smartphone, a tablet terminal, or the like. The function as the design and construction support device of this embodiment is realized by installing an application program (design and construction support application) corresponding to construction support. The design and construction support application may be configured, for example, by setting calculation formulas and macros in spreadsheet software, or may be a dedicated application created corresponding to the construction support function of this embodiment.

[0022] By the operation of the design and construction support application of this embodiment, the design and construction support device has a building-support tool compatibility determination function and a used support tool determination function.

[0023] The building-support tool compatibility determination function is a function for determining the compatibility between the building of the construction target and the support tool. Specifically, depending on the building-support tool compatibility determination function, based on the relationship between the dimensions of the support tool, the dimensions of the part (the part to be attached) in the building of the construction target to which the support tool is to be fixedly attached, and the dimensions of the eaves, it is possible to determine whether it is possible to attach the support tool to the part to be attached. In this embodiment, the case where a folded plate roof is used for the roof of the building to be constructed is taken as an example. In this case, the part to be attached in the building is the flat part of the ridge in the folded plate roof. In the following description, an example is given where the specifications of the eaves product used for attachment to a building are uniquely defined, and accordingly, the specifications of the support product used for supporting the eaves are also uniquely defined. In this case, the dimensions of the eaves member used for building / support fitting conformity determination will be predetermined according to the fact that the specifications of the eaves are single. Also, the supports will have different predetermined specifications for each gauge.

[0024] The support usage determination function is a function for determining the supports used for attaching the eaves to the building. Specifically, depending on the support usage determination function, the number of supports used for attaching the eaves to the building can be calculated. In the present embodiment, for the supports to give a gradient to the eaves, a plurality of types (gauges) of supports with dimensions (specification dimensions) defined under different specifications are prepared. Depending on the support usage determination function of the present embodiment, the number for each gauge of the supports can be calculated.

[0025] Also, depending on the support usage determination function, it is also possible to perform a determination (gradient setting feasibility determination) as to whether it is possible to set the height difference (vertical height difference) between both ends (the highest water level and the lowest water level) of the eaves according to the length of the eaves and the gradient of the eaves specified by the user's input, using the gauge of the prepared supports.

[0026] [Explanation of the sheets of the design / construction support application] When the user operates the design / construction support device to start the design / construction support application, an application screen (operation screen) of the design / construction support application is displayed on the display unit of the design / construction support device. The application screen of the design / construction support application includes a plurality of sheets corresponding to each function, and it is possible to select the sheet to be made active according to the user's operation.

[0027] The sheets of the design / construction support application include four sheets: a basic information input sheet, a building / support fitting conformity determination sheet, a support usage determination sheet, and a support information output sheet. The basic information input sheet is a sheet on which an operation of inputting basic information related to the construction of a building to which eaves are to be attached is performed. The basic information input into the basic information input sheet is included in the use support tool information output on the support tool information output sheet. The building / support tool compatibility judgment sheet is a sheet on which an input operation of parameters corresponding to the above-described building / support tool compatibility judgment function and a result of building / support tool compatibility judgment according to the input parameters are presented. The use support tool judgment sheet is a sheet on which an input operation of parameters corresponding to the above-described use support tool judgment function and a result of use support tool judgment according to the input parameters are presented. The support tool information output sheet is a sheet on which use support tool information is output. The use support tool information is information in which the result of the use support tool judgment presented on the use support tool judgment sheet is reflected.

[0028] As an operation on these sheets, for example, the user may first be made to perform an operation of inputting basic information into the basic information input sheet.

[0029] Next, the user may perform an operation on the building / support tool compatibility judgment sheet. The user can confirm whether it is possible to attach support tools to the gable roof of the building to be constructed based on the building / support tool compatibility judgment result shown on the building / support tool compatibility judgment sheet according to the operation.

[0030] When the user confirms that it is possible to fix support tools to the gable roof of the building to be constructed as described above, next, the user may perform an input operation of parameters on the use support tool judgment sheet. On the use support tool judgment sheet, the number of support tools required for attaching the eaves is presented according to the user's parameter input operation. The user can grasp the number of support tools required for attaching the eaves based on the presented content. The building / support tool compatibility judgment sheet can be created in multiple copies corresponding to each attachment position of the eaves corresponding to each drop opening in the building to be constructed, for example.

[0031] Next, the user may display the support tool usage information in which the number of support tools for each usage support tool determination sheet is reflected on the support tool information output sheet by operating the support tool information output sheet. Also, the user can output the support tool usage information displayed on the support tool information output sheet in, for example, a file format of a predetermined format.

[0032] First, an example of the form of the basic information input sheet and an example of the operation procedure for the basic information input sheet will be described. FIG. 2 shows an example of the form of the basic information input sheet. On the basic information input sheet, the user can input the destination name, date (year / month / day), property name, business office name, inputter, and management number, etc.

[0033] Next, an example of the form of the building / support tool conformity determination sheet and an example of the operation procedure for the building / support tool conformity determination sheet will be described. FIG. 3 shows an example of one form of the building / support tool conformity determination sheet. The building / support tool conformity determination sheet in the figure includes a product designation area AR1 and a roof dimension input area AR2. The user can arbitrarily select either the product designation area AR1 or the roof dimension input area AR2 and perform an input operation.

[0034] The product designation area AR1 is an area where an operation of designating a product as the folded plate roof, which is the attachment site of the support tool, is performed when designating the dimensions of the folded plate roof. In the product designation area AR1, a manufacturer name / product name input area AR11 and a determination result area AR12 are arranged.

[0035] The manufacturer name / product name input area AR11 is an area where the user can perform an operation of inputting the manufacturer name and product name of the product as the folded plate roof, which is the attachment site. The manufacturer name / product name input area AR11 includes a manufacturer name input area AR111 and a product name input area AR112.

[0036] The manufacturer name input area AR111 is an area where the manufacturer name of the product to be specified is input. The product name input area AR112 is an area where the product name of the product to be specified is input. The manufacturer name input area AR111 and the product name input area AR112 may be enabled to input the manufacturer name and the product name, respectively, by an operation of selecting menu items from, for example, a pull-down menu.

[0037] By inputting the manufacturer name and the product name (an example of dimension-related information and product-specific information) of the product into the manufacturer name input area AR111 and the product name input area AR112, respectively, the product as a folded-plate roof is uniquely specified.

[0038] The determination result area AR12 is an area that indicates whether the folded-plate roof specified according to the input operation for the manufacturer name / product name input area AR11 can be attached to the support. That is, in the determination result area AR12, it is shown whether the dimensional relationship between the specified folded-plate roof and the support conforms to the attachment of the support. In FIG. 3, an example is shown in which a display indicating conformity is made in the determination result area AR12 in response to an input being made to the manufacturer name / product name input area AR11.

[0039] Although illustration is omitted, when it is determined that the folded-plate roof as the product specified by the operation on the manufacturer name / product name input area AR11 does not conform to the support, in the determination result area AR12, a display indicating non-conformity is made in a predetermined manner.

[0040] FIG. 4 shows an example of a state when an input operation is performed on the roof dimension input area AR2 of the building / support conformity determination sheet.

[0041] The roof dimension input area AR2 is an area where an operation of inputting the dimensions of the folded-plate roof, which is the attachment site of the support, is performed when specifying the dimensions of the folded-plate roof.

[0042] In the roof dimension input area AR2, a dimension value input area AR21 and a determination result area AR22 are arranged. The dimension value input area AR21 is an area where an operation for the user to input the numerical value of the dimension of a predetermined part in the corrugated roof, which is the part to be attached, is performed. In the dimension value input area AR21 of the figure, numerical values of each dimension (dimension values) of the working width (ridge pitch), height, and shoulder width, which are each parameter (an example of dimension-related information), are set as input items.

[0043] In the dimension value input area AR21, input boxes BX21-1, BX21-2, and BX21-3 are arranged. The input box BX21-1 is an input box where an operation for inputting the dimension value of the working width is performed. The input box BX21-2 is an input box where an operation for inputting the dimension value of the height is performed. The input box BX21-3 is an input box where an operation for inputting the dimension value of the shoulder width is performed.

[0044] Fig. 5(A) shows each part of the working width Wa, height H, and shoulder width Wb when the corrugated roof is of the overlapping type. Fig. 5(B) shows each part of the working width Wa, height H, and shoulder width Wb when the corrugated roof is of the lapped type.

[0045] As an input operation for the building / support fitting conformity determination sheet, it is simple because in the product specification area AR1, it is only necessary to input the manufacturer name and product name. However, when the product as the corrugated roof of the building to be constructed is unknown, by actually measuring the working width Wa, height H, and shoulder width Wb of the corrugated roof of the building to be constructed and inputting the measured values into the dimension value input area AR21, the building / support fitting conformity determination becomes possible.

[0046] In Fig. 4, an example is shown in which, in response to the input of dimension values into each of the input boxes BX21-1, BX21-2, and BX21-3 in the dimension value input area AR21, a display indicating conformity is performed in the determination result area AR22.

[0047] FIG. 6 shows an example of a mode of a building / support fitting conformity determination sheet, as a result of input operations being performed on each of input boxes BX21-1, BX21-2, and BX21-3 in dimension value input area AR21, a display for confirmation of the object to be realized being performed in determination result area AR22. For example, in determining the conformity of a building and a support fitting, a lower limit value of a folded-plate roof that is determined to be conforming with respect to the shoulder width Wb is defined. However, if the shoulder width Wb is within a range (quasi-conforming range) from the lower limit value minus a predetermined value, depending on the actual situation of the folded-plate roof, it may be possible to fix the support fitting. Therefore, when the dimension value of the shoulder width Wb input into dimension value input area AR21 of roof dimension input area AR2 corresponds to the quasi-conforming range, as shown in FIG. 5, a display for confirmation of the object to be realized is performed in determination result area AR22.

[0048] In this way, the building / support fitting conformity determination sheet of the present embodiment determines the conformity (whether a support fitting can be attached to the attachment site) between the attachment site and the support fitting in response to receiving a simple operation such as an operation of designating a product or an operation of inputting a predetermined dimension at the attachment site, and can output a determination result. That is, by using such a building / support fitting conformity determination sheet, it is possible to easily confirm whether a support fitting can be attached to the attachment site.

[0049] In the present embodiment, the dimensions of the eaves member used for determining the conformity of the building and the support fitting are values determined in advance according to the fact that the specifications of the eaves are single. However, when the specifications of the eaves are selectable, an area may be provided in the building / support fitting conformity determination sheet where an operation of inputting predetermined dimensions such as the height and width of the target eaves is possible. Also, it may be possible to input the manufacturer name and product name indicating the product as the eaves, and the dimensions such as the height and width of the eaves may be specified from the input manufacturer name and product name. In this case, the input dimensions of the eaves are used for determining the conformity of the building and the support fitting.

[0050] Next, an example of the mode of the usage support tool determination sheet and an example of the user's operation procedure for the usage support tool determination sheet will be described. FIG. 7 shows an example of the mode of the usage support tool determination sheet. One usage support tool determination sheet shown in the figure presents information regarding the use of support tools corresponding to one downspout in the structure of a rain gutter provided in a building. In the structure of a rain gutter, one downspout is connected to one or more eaves gutters of a predetermined number of systems. That is, one usage support tool determination sheet can present information regarding the use of support tools for a predetermined system of eaves gutters connected to one downspout in the structure of a rain gutter provided in a building. In the explanation of the figure, an example is given where the rain gutter structure is such that a maximum of two eaves gutters are connected to one downspout.

[0051] In the usage support tool determination sheet of FIG. 7, a construction site designation area AR3 and usage support tool information areas AR4 (AR4-1, AR4-2) are arranged. The construction site designation area AR3 is an area where an operation for designating a construction site corresponding to the target downspout is performed in the building under construction. The usage support tool information area AR4 corresponds to each system of eaves gutters connected to the downspout designated by the construction site designation area AR3, and presents information (usage support tool information) regarding the support tools used in the corresponding eaves gutter system in response to the user's input operation. The usage support tool information here includes information indicating whether support (attachment) by a support tool is possible for the conditions of the eaves gutter corresponding to the value of the parameter input by the user's operation. Further, the usage support tool information here includes information indicating the number of support tools used for the support of the eaves gutter for each gauge number under the conditions of the eaves gutter that can be attached by the support tool. In the usage support tool determination sheet of the figure, two usage support tool information areas AR4-1 and AR4-2 are arranged in advance in response to a maximum of two systems of eaves gutters being connected to one downspout. Regarding the structure in which one gutter is connected to one row of eaves, it is sometimes called "single flow", and regarding the structure in which two rows of eaves are connected to one gutter, it is sometimes called "double flow".

[0052] As an operation on the usage support tool determination sheet, the user may first perform an operation on the construction site designation area AR3. For example, based on the design drawing of the building to be constructed, the user checks the position of the gutter corresponding to the row of eaves of interest. In the construction site designation area AR3, input boxes BX3-1, BX3-2, BX3-3, and BX3-4 are arranged. In the input box BX3-1, an operation of inputting the name of the target part in the building to be constructed is performed. In the input box BX3-2, an operation of inputting the position of the system corresponding to the row of eaves of interest is performed. In the input box BX3-3, an operation of inputting the position of the gutter corresponding to the row of eaves of interest is performed. In the input box BX3-4, an operation of inputting a numerical value as the interval between support members (support interval) in the longitudinal direction of the row of eaves of interest as a parameter is performed.

[0053] The user performs an operation of inputting the part name, system, and gutter position corresponding to the confirmed gutter position for each of the input boxes BX3-1, BX3-2, and BX3-3. In addition, the user performs an operation of inputting the numerical value of the support interval to be set for the row of eaves into the input box BX3-4. The support interval input into the input box BX3-4 is used for calculating the number of uses for each gauge number presented in the support tool number area AR42 in the usage support tool information area AR4. The support tool number area AR42 in the figure corresponds to the case where gauge numbers from "1" to "12" (1st gauge to 12th gauge) are prepared from above water to below water as the specifications of the support tools.

[0054] In the construction area designated area AR3, a calculation availability display area AR31 for indicating whether the calculation of the number of support tools to be used is possible is arranged. In the construction area designated area AR3 in the figure, an example is shown where a display indicating that the calculation of the number of support tools to be used is possible is made.

[0055] In the calculation availability display area AR31, when at least one of the input boxes BX3-1, BX3-2, BX3-3, BX3-4 is in an uninput state, a display indicating that the calculation is impossible is made. Also, in the calculation availability display area AR31, when the numerical value of the support interval input to the input box BX3-4 exceeds a predetermined upper limit value (support interval upper limit value), a display indicating that the calculation is impossible is made.

[0056] Next, the user performs an input operation on the use support tool information area AR4 in order to grasp the number of support tools required for the construction of attaching the target eaves to the building. In the use support tool information area AR4, input boxes BX4-1 and BX4-2 for inputting parameters are arranged. In the input box BX4-1, an operation for inputting a parameter as the length of the target eaves (eaves length) is performed. In the input box BX4-2, an operation for inputting a parameter as the gradient set for the target eaves is performed.

[0057] The user inputs the length and gradient of the target eaves into the input boxes BX4-1 and BX4-2 respectively. The attachment availability display area AR41 displays whether it is possible to attach the target eaves to the building using support tools in the case of the combination of the eaves length and gradient input to the input boxes BX4-1 and BX4-2.

[0058] First, the range of the gradient value (permissible gradient range) that can be input into the input box BX4-2 is predetermined. When the gradient value input into the input box BX4-2 is outside the permissible gradient range, as shown in the usage support tool information area AR4-1 in FIG. 8, a display indicating that it cannot be attached is made in the attachment permission prompt area AR41. Also, in this case, in the usage support tool information area AR4-1, a message MS1 prompting to re-enter the value of the gradient parameter so as to be within the permissible gradient range is displayed. Also, when such a display indicating that it cannot be attached is made in the attachment permission prompt area AR41, a display indicating that calculation is not possible is also made in the calculation permission prompt area AR31 in the construction site designation area AR3 in conjunction.

[0059] Further, depending on the eaves length and gradient input into the input boxes BX4-1 and BX4-2, the height difference (water level upper and lower height difference) between the uppermost water level part and the lowermost water level part caused by the gradient of the target eaves is uniquely obtained. When the water level upper and lower height difference obtained in this way exceeds a predetermined upper limit value (height difference upper limit value), even if a support tool with specified dimensions for each thread count is used, the water level upper and lower height difference cannot be set.

[0060] Note that the water level upper and lower height difference calculated based on the eaves length and gradient input into the input boxes BX4-1 and BX4-2 as described above may be corrected according to the specification of the size of the support tool. Such correction may be performed in response to a specification in which the support tool is made longer by a predetermined dimension for each thread count. As a specific example, when the support tool is specified to be made longer by a dimension difference of 7 mm each time the thread count increases in order, the water level upper and lower height difference (mm) calculated based on the input eaves length and gradient is corrected to the nearest value among the multiples of the dimension difference of 7 mm. For example, when the water level upper and lower height difference calculated based on the input eaves length and gradient is 26 mm, the water level upper and lower height difference may be corrected to 28 mm.

[0061] When the water level difference determined by the combination of the input eaves length and gradient exceeds the upper limit value of the level difference, as shown in the usage support tool information area AR4-1 of Fig. 9, a display indicating that installation is not possible is made in the installation availability prompt area AR41. Also, in this case, in the usage support tool information area AR4-1, a message MS2 prompting the user to re-enter the parameters (eaves length, gradient) so that the water level difference is below the upper limit value of the level difference is displayed.

[0062] In the case of a single-flow where there is one system of the target eaves, the user may perform an operation of entering the parameters (eaves length, gradient) in either one of the usage support tool information areas AR4-1 and AR4-2. On the other hand, in the case of a two-flow where there are two systems of the target eaves, the user may perform an operation of entering the parameters (eaves length, gradient) corresponding to each system of the eaves in each of the usage support tool information areas AR4-1 and AR4-2. In this case, the eaves length and gradient for each system may be different.

[0063] When the parameters of the two systems of eaves are entered, the lowest underwater parts of each of the two systems of eaves are connected to the same drain opening. For this reason, it is necessary for the gauge numbers of the support tools attached to the lowest underwater parts of each of the two systems of eaves to be common. However, depending on the relationship between the parameters (eaves length, gradient) entered for each of the two systems, there may be cases where the gauge numbers of the support tools attached to the lowest underwater parts of each of the two systems of eaves cannot be set to be common. In such cases, as shown in Fig. 10, in each of the usage support tool information areas AR4-1 and AR4-2, a display indicating that installation is not possible is made in the installation availability prompt area AR41.

[0064] Also, in this case, in each of the usage support tool information areas AR4-1 and AR4-2, a message MS3 prompting the user to re-enter the parameters (eaves length, gradient) that can make the gauge numbers of the support tools attached to the lowest underwater parts of each of the two systems of eaves common is displayed.

[0065] Also, for example, when parameters are input into each of the use support tool information areas AR4-1 and AR4-2 corresponding to two rows of eaves, (Condition A) The support interval input into the construction part designation area AR3 is less than or equal to the upper limit value of the support interval. (Condition B) The vertical height difference due to the parameters (eave length, gradient) input into each of the use support tool information areas AR4-1 and AR4-2 is less than or equal to the upper limit value of the height difference. (Condition C) The gauge numbers of the support tools attached to the lowest part of each of the two rows of eaves are the same. When the three conditions are satisfied, as shown in FIG. 7, a display indicating that attachment is possible is performed in each of the attachment possible / impossible presentation areas AR41 of the use support tool information areas AR4-1 and AR4-2.

[0066] Also, in each of the use support tool number areas AR42 of the use support tool information areas AR4-1 and AR4-2, the number for each gauge number of the support tools used for attaching the target eaves and the total of the numbers for each gauge number are shown. Here, when attaching the eaves gutter, ideally, it is preferably equal in number for each gauge of the support tool to be used. However, depending on the length of the eaves gutter and the support interval conditions, the number may not be the same for each gauge of the support tool to be used. Also in the example of the figure, in the used support tool information area AR4-1, since the required number of support tools from gauge 1 to gauge 5 is 24, after equally allocating 4 for each gauge, 4 remain as a remainder. Further, in the used support tool information area AR4-2, since the required number of support tools from gauge 1 to gauge 5 is 12, after equally allocating 2 for each gauge, 2 become the remainder. In such a case, for example, according to a predetermined rule (support tool number calculation rule), it is added so that the remainder is appropriately allocated to the number of support tools of the gauge on the water upper side or the water lower side. Specifically, in the used support tool information area AR4-1, for the number of support tools of each of the 4th and 5th gauges on the water lower side, 2 of the 4 remainders are allocated and added to become 6. Also, in the used support tool information area AR4-1, for the number of support tools of each of the 4th and 5th gauges on the water lower side, 1 of the 2 remainders is allocated and added to become 3. As the number of support tools of the same gauge increases, the gradient becomes gentle. Therefore, regarding which side, the water upper side or the water lower side, to add the number of support tools with a remainder, it may be determined in consideration of, for example, which of the following advantages should be prioritized. First, when allocating the remainder to the number of support tools on the water lower side, since the gradient on the water lower side becomes gentle, it is easy to construct when joining the eaves gutter and the vertical drain, joint, etc., and it is difficult to form a gap, so it is possible to suppress the occurrence of water leakage. Also, when allocating the remainder to the number of support tools on the water upper side, since the gradient on the water upper side becomes gentle, it is possible to obtain ease of construction and difficulty in forming a gap when joining the gutters on the water upper side. Also, by making the gradient on the water upper side gentle, the gradient on the water lower side can be strengthened, for example, to improve the water flow around the drain and suppress the occurrence of mold and moss around the drain.

[0067] In addition, in the additional information areas AR43 in the usage support tool information areas AR4-1 and AR4-2 respectively, the vertical and horizontal height differences corresponding to the eaves and purlin system, the number of yarn counts used (number of warp threads), and the total number of support tools used (number of support tools) are presented as additional information.

[0068] Note that when parameters (eave and purlin length, gradient) are input into either one of the usage support tool information areas AR4-1 and AR4-2 corresponding to one system of eaves and purlins, when the above conditions A and B are satisfied, in the usage support tool information area AR4 where the parameters are input, a display similar to FIG. 7 is performed.

[0069] As described above, a plurality of usage support tool determination sheets are created corresponding to each construction site, and by the user performing the same operations as above, usage support tool information about the target eaves and purlins can be presented.

[0070] The user can confirm the list of usage support tool information presented on the usage support tool determination sheet as described above using the support tool information output sheet. FIG. 11 shows an example form of the support tool information output sheet. The support tool information output sheet includes a header area AR5 and a support tool information area AR6. The header area AR5 presents basic information about the building under construction. The content input into the basic information input sheet (FIG. 2) is reflected in the header area AR5. In the support tool information area AR6, usage support tool information based on the content of the created usage support tool determination sheet is presented. In the figure, each row corresponding to the part name indicates the usage support tool information corresponding to one usage support tool determination sheet. In the support tool information area AR6, the number of support tools used for each eaves and purlin is shown for each yarn count, and the total number of support tools used for each eaves and purlin is also shown. In addition, in the support tool information area AR6, the total number for each yarn count of the support tools used is shown. In addition, in the support tool information area AR6, the total number of support tools used for each eave is further added up and shown as the total count.

[0071] An update button BT51 and a file output button BT52 are arranged on the support tool information output sheet. The update button BT51 is a button for instructing an operation to update the content of the support tool information output sheet so that when the content of the basic information sheet or the used support tool determination sheet is changed by an operation, the changed content is reflected in the support tool information output sheet. Note that even if the update button BT51 is not operated, the changes made to the basic information sheet or the used support tool determination sheet may be linked and reflected in the support tool information output sheet as well. The file output button BT52 is a button for instructing an operation to output the content of the support tool information output sheet as a file in a predetermined format.

[0072] [Functional Configuration Example of Design and Construction Support Device] With reference to FIG. 12, a functional configuration example of the design and construction support device 100 of the present embodiment will be described. The design and construction support device 100 may be configured as hardware including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and the like. The functions of the design and construction support device 100 shown in the figure are realized by the CPU provided in the design and construction support device 100 executing a program of a design and construction support application.

[0073] The design and construction support device 100 in FIG. 12 includes a user interface unit 101, a control unit 102, and a storage unit 103. The user interface unit 101 is a part including an operation unit and a display unit provided in the design and construction support device 100.

[0074] The control unit 102 executes various controls in the design and construction support device 100. The control unit 102 includes an acquisition unit 121 (an example of a first acquisition unit and a second acquisition unit), a conformity determination unit 122, a calculation unit 123, and an output unit 124.

[0075] The acquisition unit 121 acquires information such as basic information and parameters input in response to operations performed on the sheets of the design and construction support application.

[0076] The conformity determination unit 122 determines the conformity (whether a support can be attached to the attachment site in the building) between the attachment site in the building and the support based on the information input in the building - support conformity determination sheet.

[0077] The calculation unit 123 calculates the number of each gauge of the support to be used for the eaves of the construction target based on the information (parameter values such as support interval, eaves length, gradient, etc.) input in the support usage determination sheet. Further, the calculation unit 123 may also determine whether it is possible to attach the eaves with the support corresponding to the parameter values input in the support usage determination sheet.

[0078] The output unit 124 (an example of a first output unit and a second output unit) outputs the determination result by the conformity determination unit 122. The output of the determination result in this case may be performed as a display in the determination result areas AR12 and AR22 in the building - support conformity determination sheet. Also, the output unit 124 outputs support usage information. The output of the support usage information in this case includes a display by the support information output sheet and an output of a file in response to an operation of the file output button BT52 in the support information output sheet.

[0079] The storage unit 103 stores various information related to the design and construction support device 100. The storage unit 103 includes a support information storage unit 131, a product information storage unit 132, and a calculation rule storage unit 133.

[0080] The support information storage unit 131 stores support information. The support information includes information on the dimensions for each gauge of the support.

[0081] The product information storage unit 132 stores product information. The product information includes the manufacturer name, product name, dimensions, etc. as the specifications for each product as the roof (corrugated roof) which is the attachment site of the support tool.

[0082] The calculation rule storage unit 133 stores calculation rules (support tool quantity calculation rules) used by the calculation unit 123 to calculate the quantity for each gauge of the support tool used for the eaves and rafter attachment. Such a calculation rule may be information in a table structure showing the specification quantity for each gauge of the support tool, corresponding to, for example, each combination of the eaves and rafter length and the gradient. Also, the calculation rule storage unit 133 may store, as calculation rules, the upper limit value of the support interval used by the calculation unit 123 for determining whether calculation is possible, the allowable gradient range used for determining whether attachment is possible, the upper limit value of the height difference, etc.

[0083] [Example of processing procedure] With reference to the flowchart of FIG. 13, an example of the processing procedure of the design and construction support device 100 corresponding to the operation procedure example performed by the user on the design and construction support application operating on the design and construction support device 100 will be described. Step S100: The user performs an operation of inputting basic information to the basic information input sheet. In the design and construction support device 100, the acquisition unit 121 acquires the input basic information.

[0084] Step S102: Next, the user performs either an input of the manufacturer name and product name to the manufacturer name / product name input area AR11 or an input of the dimensions of the corrugated roof to the dimension value input area AR21 as an input operation on the building / support tool compatibility determination sheet. In the design and construction support device 100, the acquisition unit 121 acquires the manufacturer name, product name, or the dimensions of the corrugated roof input by the user, and the compatibility determination unit 122 executes a building / support tool compatibility determination based on the acquired information. The output unit 124 displays the determination result in the determination result area AR12 or the determination result area AR22.

[0085] Step S104: Next, the user performs an operation of inputting the construction site (site name, system, position of the outlet) and an operation of inputting the parameters for the determination of the support tool to be used (support interval, length of the eaves, gradient) on the support tool determination sheet. In the design and construction support device 100, the acquisition unit 121 acquires the construction site input by the user and the parameters for the determination of the support tool to be used, and the calculation unit 123 executes the determination of the support tool to be used based on the acquired information. The determination of the support tool to be used includes a calculation feasibility determination, an attachment feasibility determination, and a calculation of the number for each gauge number of the support tool. The output unit 124 displays the result of the calculation feasibility determination in the calculation feasibility presentation area AR31, displays the result of the attachment feasibility determination in the attachment feasibility presentation area AR41, and displays the support tool information based on the calculation result of the number for each gauge number of the support tool in the support tool number area AR42 and the additional information area AR43.

[0086] Step S106: Next, the user performs an operation to activate the support tool information output sheet. The output unit 124 of the design and construction support device 100 displays the basic information input to the basic information input sheet in step S100 in the header area AR5 of the activated support tool information output sheet, and displays the support tool information obtained in step S104 in the support tool information area AR6. In addition, the output unit 124 executes a process of outputting the display content of the support tool information output sheet as a file in a predetermined format in response to the operation of the file output button BT52 arranged on the support tool information output sheet.

[0087] Referring to the sequence diagram of FIG. 14, a processing procedure example executed by the design and construction support device 100 of the present embodiment in response to an operation on the building and support tool conformity determination sheet (FIGS. 3, 4, and 6) will be described.

[0088] Step S200: The user is made to select either the manufacturer name and product name input area AR11 or the dimensional value input area AR21 as the target of the input operation on the building and support tool conformity determination sheet. Here, the user selected the manufacturer name and product name input area AR11 as the operation target and performed the input operations for the manufacturer name and the product name. The acquisition unit 121 of the design and construction support device 100 acquires the input manufacturer name and product name.

[0089] Step S202: In the design and construction support device 100, the conformity determination unit 122 acquires the dimensions of the folded plate roof as a product specified by the manufacturer name and product name acquired in step S20. For this purpose, the conformity determination unit 122 searches the product information storage unit 132 for the product information associated with the combination of the manufacturer name and product name acquired in step S200. The conformity determination unit 122 acquires the dimensions of the folded plate roof as a product included in the searched product information.

[0090] Step S204: The conformity determination unit 122 collates the dimensions of the folded plate roof acquired in step S202 with the dimensions of the support tool indicated by the support tool information stored in the support tool information storage unit 131.

[0091] Step S206: Based on the result of the collation in step S204, the conformity determination unit 122 determines the suitability (conformity) of the attachment of the folded plate roof (the part to be attached) and the support tool. For example, the conformity determination unit 122 may determine whether there is conformity based on whether the dimension of the shoulder width of the folded plate roof is larger than the dimension of the corresponding part of the support tool. Also, the conformity determination unit 122 may determine whether there is conformity based on whether the height of the support tool is longer than the combined length of the height H of the roof (Fig. 5) and the dimension of the height of the member as the eaves.

[0092] Step S208: The output unit 124 displays the determination result regarding the conformity in step S206 in the determination result area AR12 within the product specification area AR1.

[0093] Step S220: Further, as an input operation on the building - support fitting determination sheet, the user selected the dimensional value input area AR21 as the operation target and performed an input operation for the dimensions (working width, height, shoulder width) of the folded - plate roof. The acquisition unit 121 of the design and construction support device 100 inputs the inputted dimensions (working width, height, shoulder width) of the folded - plate roof as parameters to be used for conformity determination.

[0094] Step S222: In the design and construction support device 100, the conformity determination unit 122 collates the dimensions of the folded - plate roof acquired in Step S220 with the dimensions of the support fittings indicated by the support fitting information stored in the support fitting information storage unit 131.

[0095] Step S224: Based on the result of the collation in Step S222, the conformity determination unit 122 determines the suitability (conformity) of the attachment of the folded - plate roof (the part to be attached) and the support fittings.

[0096] Step S226: The output unit 124 displays the determination result regarding the conformity in Step S224 in the determination result area AR22 within the roof dimension input area AR2.

[0097] Next, with reference to the sequence diagram in FIG. 15, an example of the processing procedure executed by the design and construction support device 100 of the present embodiment in response to an operation on the usage support fitting determination sheet (FIGS. 7 to 10) will be described.

[0098] The user can perform a designation operation for the construction part (Step S300) on the input boxes BX3 - 1, BX3 - 2, BX3 - 3 within the construction part designation area AR3, an input operation for the parameter of the support interval on the input box BX3 - 4 within the construction part designation area AR3 (Step S304), an input operation for each parameter of the eaves length and gradient on the input boxes BX4 - 1, BX4 - 2 in the usage support fitting information area AR4 - 1 (Step S310), and an input operation for each parameter of the eaves length and gradient on the input boxes BX4 - 1, BX4 - 2 in the usage support fitting information area AR4 - 2 (Step S316) as input operations on the building - support fitting determination sheet.

[0099] When there is one type of eaves gutter system connected to the drop opening of the construction site to be targeted, the user may perform an input operation of parameters for any of the usage support tool information areas AR4-1. On the other hand, when there are two types of eaves gutter systems connected to the drop opening of the construction site to be targeted, the user may perform an input operation of parameters corresponding to each system for each of the usage support tool information areas AR4-1 and AR4-2. In the following description, the eaves gutter system corresponding to the usage support tool information area AR4-1 may be described as system A, and the eaves gutter system corresponding to the usage support tool information area AR4-2 may be described as system B.

[0100] Step S300: The user performed an operation (construction site designation operation) of inputting the construction site (site name, system, drop opening position) to the input boxes BX3-1, BX3-2, and BX3-3 in the construction site designation area AR3.

[0101] In step S300, it is sufficient that an input operation is performed on at least one of the input boxes BX3 (BX3-1, BX3-2, BX3-3). When there is an uninput input box BX3, the output unit 124 may cause a display indicating non-calculability to be made in the calculation availability prompt area AR31. Also in step S300, the user can perform an input operation to change the information of the input box BX3 in which information has already been input.

[0102] Step S302: In the design and construction support apparatus 100, the acquisition unit 121 acquires the construction site (site name, system, drop opening position) input to the input boxes BX3-1, BX3-2, and BX3-3 in step S300. The information of the construction site (site name, system, drop opening position) thus acquired is reflected on the support tool information output sheet.

[0103] Step S304: Also, the user performed an operation of inputting a numerical value of the support interval to the input box BX3-4 in the construction site designation area AR3.

[0104] Step S306: In response to the input of the numerical value of the support interval in Step S304, the calculation unit 123 sets the input numerical value of the support interval as a calculation parameter. Then, the calculation unit 123 executes a calculation using the numerical value of the support interval set as the calculation parameter. Specifically, the calculation unit 123 may perform a calculation feasibility determination by comparing the numerical value of the support interval set as the calculation parameter with the upper limit value defined for the support interval. Further, when the length and gradient of the eaves have been input and set as calculation parameters in at least one of the already used support tool information areas AR4-1 and AR4-2, the calculation unit 123 may recalculate the number of support tools used for each thread count using the length and gradient of the eaves and the support interval.

[0105] Step S308: The output unit 124 performs a display according to the calculation result in Step S306 on the used support tool determination sheet. That is, the output unit 124 causes a display indicating the result of the calculation feasibility determination in Step S306 to be performed in the calculation feasibility presentation area AR31. In addition, the output unit 124 causes a display indicating the result of recalculating the number of support tools used for each thread count to be performed in the support tool number area AR42.

[0106] Step S310: Also, the user performs an input operation of the numerical values of the eaves length and gradient on the input boxes BX4 (BX4-1, BX4-2) in the used support tool information area AR4-1 for the eaves of system A. In this Step S310, the user may be made to perform an input operation on at least one of the input boxes BX4 (BX4-1, BX4-2), or may perform an input operation to change the numerical value of the already input input box BX4.

[0107] Step S312: In response to the input operation in Step S310, the calculation unit 123 sets the input numerical values of the eaves length and gradient as calculation parameters. Furthermore, the calculation unit 123 uses the length of the eaves and the numerical values of the gradient set as calculation parameters, and the parameter of the support interval set in step S306 to execute the calculation of the number of support tools to be used. The calculation of the number of support tools to be used here also includes recalculation in response to a change in at least one of the length of the eaves and the gradient. In addition, as described in detail with reference to FIG. 7, the calculation unit 123 may perform a process of adding the number assigned from the remainder to the upper or lower count when a remainder occurs after equally dividing the number for each count to be used. In calculating the number of support tools to be used, the calculation unit 123 may use the support tool number calculation rule stored in the support tool number calculation rule storage unit 133. In addition, when calculating the number of support tools to be used, the calculation unit 123 performs an attachment determination based on whether the vertical height difference between above and below water obtained from the length of the eaves and the gradient set as calculation parameters exceeds the upper limit value of the height difference. Note that when obtaining the vertical height difference between above and below water, the calculation unit 123 may correct the value of the vertical height difference between above and below water calculated from the length of the eaves and the gradient to a value that is a multiple of the dimensional difference determined by the specifications of the support tool.

[0108] Step S314: The output unit 124 performs a display according to the calculation result in step S312 on the support tool determination sheet. That is, the output unit 124 causes the attachment determination result by the calculation unit 123 to be displayed in the attachment determination presentation area AR41 of the support tool information area AR4-1. Further, when an attachment determination result of "attachable" is obtained, the output unit 124 causes the calculation result of the number of specification support tools by the calculation unit 123 to be displayed in the support tool number area AR42 of the support tool information area AR4-1.

[0109] Step S316: Also, the user performs an input operation of the numerical values of the length of the eaves and the gradient on the input boxes BX4 (BX4-1, BX4-2) in the support tool information area AR4-2 for the eaves of system B. In this case, the calculation unit 123 and the output unit 124 may execute the same processes as steps S312 and S314 described above corresponding to the support tool information area AR4-2 in steps S318 and S320.

[0110] <Second Embodiment> Next, the second embodiment will be described. In the usage support tool determination function of the first embodiment described above, when presenting usage support tool information corresponding to both flows in which two eaves-to-roof systems are connected to one drop opening, for each of the usage support tool information areas AR4-1 and AR4-2 in the usage support tool determination sheet, the eaves-to-roof length and gradient are individually input.

[0111] In contrast, in this embodiment, for example, when determining the usage support tool for both flows, if the condition is that the vertical height difference of each of the two eaves-to-roof systems is the same, after inputting the eaves-to-roof length and gradient into each of the input boxes BX4-1 and BX4-2 in one of the usage support tool information areas AR4 (AR4-1, AR4-2), for the other usage support tool information area AR4, it is sufficient to input the eaves-to-roof length into the input box BX4-1 and not input the gradient into the input box BX4-2. That is, in this embodiment, when determining the usage support tool corresponding to both flows, it is possible to omit the input of the gradient parameter for one of the two systems.

[0112] In the following description, the two eaves-to-roof systems corresponding to one drop opening are referred to as the first system and the second system, respectively. Here, the user input the eaves-to-roof length and gradient into each of the input boxes BX4-1 and BX4-2 in the usage support tool information area AR4-1 corresponding to the eaves-to-roof of the first system, and input the eaves-to-roof length into the input box BX4-1 in the usage support tool information area AR4-2 corresponding to the eaves-to-roof of the second system.

[0113] In this case, in response to the input of the parameters as described above, the calculation unit 123 of the design and construction support device 100 calculates the water level difference, the number of crossflows, and the number of supports corresponding to the first system based on the eaves length and the gradient input to the use support tool information area AR4-1. The output unit 124 causes the calculated water level difference, the number of crossflows, and the number of supports to be displayed in the additional information area AR43 in the use support tool information area AR4-1.

[0114] Further, the calculation unit 123 of the design and construction support device 100 inputs the water level difference calculated corresponding to the first system as one of the parameters for calculating the number of crossflows and the number of supports of the second system. In response to the input of the water level difference as a parameter corresponding to the second system in this way, the output unit 124 displays the water level difference in the additional information area AR43 of the use support tool information area AR4-2.

[0115] As described above, for the second system, the eaves length input by the user to the input box BX4-1 of the use support tool information area AR4-2 and the water level difference input by the calculation unit 123 are obtained as parameters. Therefore, the calculation unit 123 calculates the gradient of the eaves of the second system using the parameters of the eaves length and the water level difference input corresponding to the second system. Further, the calculation unit 123 calculates the number of crossflows and the number of supports corresponding to the second system using the gradient calculated as described above and the eaves length input to the input box BX4-1 of the use support tool information area AR4-2.

[0116] The output unit 124 displays the calculated gradient of the eaves of the second system in the input box BX4-2 of the use support tool information area AR4-2. Further, the output unit 124 causes the calculated number of crossflows and the number of supports of the second system by the calculation unit 123 to be displayed in the additional information area AR43 of the use support tool information area AR4-2. The user can confirm the required number of crossflows and the number of supports for each system's eaves in both flows using the use support tool determination sheet displayed as described above.

[0117] <Third Embodiment> Next, the third embodiment will be described. In the previous first embodiment, when performing the use support tool determination (calculation of the number of eaves and the number of use support tools) corresponding to one row of eaves, the length and gradient of the eaves were input to the use support tool information area AR4 in the use support tool determination sheet.

[0118] In contrast, in this embodiment, when performing the use support tool determination corresponding to one row of eaves, instead of the gradient, the vertical height difference is input to the use support tool information area AR4 in the use support tool determination sheet. In this case, although not shown in the figure, it may be shown that the parameter to be input to the input box BX4-2 in the use support tool information area AR4 of this embodiment is the vertical height difference. Also, in the additional information area AR43 of the use support tool information area AR4, the gradient may be shown instead of the vertical height difference.

[0119] In this embodiment, when the user performs the use support tool determination for one row of eaves, as an operation on one use support tool information area AR4 in the use support tool determination sheet, the user inputs the length of the eaves to the input box BX4-1 and the vertical height difference to the input box BX4-2.

[0120] In this case, the calculation unit 123 may perform a determination (gradient setting availability determination) as to whether the input vertical height difference can be set according to the gauge number of the prepared support tool. Further, the calculation unit 123 may calculate the gradient based on the length of the eaves input to the input box BX4-1 and the vertical height difference input to the input box BX4-2, and then determine whether the calculated gradient is within the allowable gradient range. When the calculation unit 123 determines that the input vertical height difference cannot be set, or when the gradient exceeds the allowable gradient range, the output unit 124 may display that it is not possible to install in the installation availability prompt area AR41.

[0121] When the calculation unit 123 determines that the eaves gutter can be attached based on the input water level difference and the calculated gradient, it calculates the number of downflows and the number of fittings used based on the input eaves gutter length and the water level difference. The output unit 124 may display the calculated gradient, the number of downflows, and the number of fittings used in the additional information area AR43.

[0122] <Fourth Embodiment> Next, the fourth embodiment will be described. In the usage support tool determination function of the above-described third embodiment, when presenting usage support tool information corresponding to the case of both flows in which two eaves gutter systems are connected to one drain opening, for each of the usage support tool information areas AR4-1 and AR4-2 in the usage support tool determination sheet, the eaves gutter length and the water level difference are to be input.

[0123] On the other hand, in the present embodiment, when determining the usage support tool in the case of both flows, when the gradients of the two eaves gutter systems are made common, after inputting the eaves gutter length and the water level difference into the respective input boxes BX4-1 and BX4-2 in one of the usage support tool information areas AR4 (AR4-1, AR4-2), for the other usage support tool information area AR4, it is not necessary to input the water level difference into the input box BX4-2 after inputting the eaves gutter length into the input box BX4-1. That is, in the present embodiment, when determining the usage support tool corresponding to both flows, the input of the parameter of the water level difference can be omitted for one of the two systems.

[0124] Here, the user inputs the eaves gutter length and the water level difference into the respective input boxes BX4-1 and BX4-2 in the usage support tool information area AR4-1 corresponding to the eaves gutter of the first system, and inputs the eaves gutter length into the input box BX4-1 in the usage support tool information area AR4-2 corresponding to the eaves gutter of the second system.

[0125] In this case, in response to the input of the parameters as described above, the calculation unit 123 of the design and construction support device 100 calculates the gradient corresponding to the first system based on the eaves length and the vertical and horizontal height difference input to the usage support tool information area AR4-1, and also calculates the number of crossflows and the number of support tools. The output unit 124 causes the gradient, the number of crossflows, and the number of support tools calculated by the calculation unit 123 to be displayed in the additional information area AR43 in the usage support tool information area AR4-1.

[0126] Furthermore, the calculation unit 123 inputs the gradient calculated corresponding to the first system as one of the parameters for calculating the number of crossflows and the number of support tools of the second system. In response to the input of the gradient corresponding to the second system in this way, the output unit 124 displays the gradient in the additional information area AR43 of the usage support tool information area AR4-2 corresponding to the second system.

[0127] As described above, for the second system, the eaves length input by the user to the input box BX4-1 of the usage support tool information area AR4-2 and the gradient input by the calculation unit 123 are obtained as parameters. Therefore, the calculation unit 123 calculates the vertical and horizontal height difference of the eaves of the second system using the eaves length and the gradient input corresponding to the second system. In addition, the calculation unit 123 calculates the number of crossflows and the number of support tools corresponding to the second system using the vertical and horizontal height difference calculated as described above and the eaves length input to the input box BX4-1 of the usage support tool information area AR4-2.

[0128] The output unit 124 displays the vertical and horizontal height difference of the eaves of the second system calculated by the calculation unit 123 as described above in the input box BX4-2 of the usage support tool information area AR4-2. In addition, the output unit 124 causes the number of crossflows and the number of support tools of the second system calculated by the calculation unit 123 to be displayed in the additional information area AR43 of the usage support tool information area AR4-2. Thus, also in this embodiment, the user can confirm the number of crossflows and the number of support tools required for the eaves of each system in both flows using the usage support tool determination sheet on which the display is performed as described above.

[0129] In the usage support tool determination sheet of each of the above embodiments, the support interval is to be input to the input box BX3-4 in the construction site designation area AR3. Therefore, when a plurality of eaves systems are provided for one drain outlet so as to flow in both directions, the support interval can be set commonly for the plurality of eaves systems. The support interval is often made common for each eaves system. For this reason, in each of the above embodiments, the support interval is input to the input box BX3-4 in the construction site designation area AR3, and the support interval in each eaves system can be set by inputting the support interval once. On the other hand, there may be a case where it is desired to individually set the support interval for each eaves system. In response to such a case, for example, regarding the usage support tool determination sheet, it is possible to input the support interval for each eaves system, and the calculation unit 123 may calculate the attachment possibility determination, the number of proper flows, the number of support tools, etc. using the input support interval parameters for each eaves system.

[0130] Further, in the usage support tool determination sheet of each of the above embodiments, the parameters to be input for the usage support tool determination are three, namely, the support interval, the length of the eaves, and the gradient or the water level difference. In this case, in each of the above embodiments, the user is to input the length of the eaves to the usage support tool determination sheet. Regarding the use support tool determination sheet of each of the above embodiments, instead of inputting the length of the eaves as described above, the number of support tools may be input. In this case, when making a determination regarding the use support tool, the user is made to input three parameters, namely, the support interval, the number of support tools, and the gradient or the vertical height difference, as parameters to the use support tool determination sheet. In this case, the calculation unit 123 may calculate the length of the eaves using the support interval and the number of support tools among the input support interval, number of support tools, gradient, or vertical height difference. The calculation unit 123 may calculate the vertical height difference using the calculated length of the eaves and the input gradient, or may calculate the gradient using the calculated length of the eaves and the input vertical height difference. Further, the calculation unit 123 may calculate the number of drip flows using the calculated vertical height difference or gradient and the calculated length of the eaves.

[0131] <Modification Example> Hereinafter, modification examples of each of the above embodiments will be described. [First Modification Example] The design and construction support device 100 of each of the above embodiments may also be capable of determining (evaluating) the water-receiving property of the eaves that is attached by the support tool. The water-receiving property is the performance related to receiving rainwater flowing down from the roof by the eaves.

[0132] In this case, for example, the calculation unit 123 of the design and construction support device 100 makes a determination (first determination) as to whether the difference between the dimension of the height as a member of the support tool and the dimension of the height as a member of the eaves is within a range of a predetermined water-receiving possible height. Further, a determination (second determination) is made as to whether the distance (length) from the eaves tip of the roof to the protruding dimension of the eaves is equal to or greater than a predetermined water-receiving possible width. Corresponding to the second determination, the storage unit 103 may store the dimension of the eaves tip of the roof and the protruding dimension of the eaves.

[0133] When a determination result that it is within the range of the water-receiving possible height and is equal to or greater than the water-receiving possible width is obtained, the calculation unit 123 may determine that it has the water-receiving property, and when a determination result that it is outside the range of the water-receiving possible height or less than the water-receiving possible width is obtained, the calculation unit 123 may determine that it does not have the water-receiving property.

[0134] The output unit 124, although not shown in the drawings, may display information regarding the determination result of the water-receiving property, for example, in the usage support tool information area AR4. Also, the output unit 124, although not shown in the drawings, may display information regarding the determination result of the water-receiving property in correspondence with the target eaves on the support tool information output sheet.

[0135] [Second Modification Example] The design and construction support device 100 of each of the above embodiments may evaluate the wind pressure resistance performance of the eaves attached by the support tool. In evaluating the wind pressure resistance performance of the eaves, the calculation unit 123 of the design and construction support device 100 may calculate the wind pressure of the eaves according to, for example, the wind pressure calculation formula defined by the Building Standards Act, and based on the calculated wind pressure, determine whether the eaves attached by the support tool satisfy the wind pressure resistance performance.

[0136] Note that the calculation unit 123 may be able to change the support interval of the support tool for the eaves so that, for example, the wind pressure resistance performance is enhanced, based on the calculated wind pressure of the eaves.

[0137] The output unit 124, although not shown in the drawings, may display information regarding the evaluation result of the wind pressure resistance performance, for example, in the usage support tool information area AR4. Also, the output unit 124, although not shown in the drawings, may display information regarding the evaluation result of the wind pressure resistance performance in correspondence with the target eaves on the support tool information output sheet.

[0138] [Third Modification Example] The design and construction support device 100 of each of the above embodiments may evaluate the snow load resistance performance of the eaves attached by the support tool. In evaluating the snow load resistance performance of the eaves, the calculation unit 123 of the design and construction support device 100 may calculate the snow load of the eaves according to, for example, the calculation formula defined by the Building Standards Act, and determine whether the snow load resistance performance of the eaves attached by the support tool is satisfied based on whether the calculated snow load satisfies the conditions defined in the area corresponding to the building under construction.

[0139] Note that the calculation unit 123 may be configured to be able to change the support interval of the support for the eaves based on the calculated snow load on the eaves, for example, so as to enhance the snow load resistance performance.

[0140] Although not shown in the figure, the output unit 124 may display information regarding the evaluation result of the snow load resistance performance, for example, in the usage support tool information area AR4. Also, although not shown in the figure, the output unit 124 may display information regarding the evaluation result of the snow load resistance performance corresponding to the target eaves on the support tool information output sheet.

[0141] [Fourth Modification Example] The design and construction support device 100 of each of the above embodiments may calculate the cost of eaves construction. In calculating the cost of eaves construction, the storage unit 103 of the design and construction support device 100 may store price information indicating the price of the eaves members, the price for each gauge of the support tools, the labor cost related to the eaves construction, etc. Furthermore, the calculation unit 123 of the design and construction support device 100 may refer to the price information to obtain the cost of the eaves corresponding to the length of the eaves to be constructed input in the usage support tool determination sheet, the cost of the support tools corresponding to the breakdown of the number of usage support tools calculated corresponding to the eaves, and the labor cost corresponding to the eaves length, thereby calculating the cost of eaves construction. Although not shown in the figure, the output unit 124 may display the calculated cost of eaves construction on the usage support tool determination sheet. Also, although not shown in the figure, the output unit 124 may display the calculated cost of eaves construction on the support tool information output sheet. Note that the design and construction support device 100 may be configured to be able to calculate and output the construction cost of the rain gutter including the eaves and the vertical members by including, for example, the price of the members corresponding to the vertical members, the price of the support tools for the vertical members, the labor cost for the vertical members, etc. in the price information.

[0142] [Fifth Modification Example] The calculation unit 123 of the design and construction support device 100 of each of the above embodiments may calculate the greenhouse gas emissions corresponding to the construction of the eaves gutter.

[0143] In the life cycle from the manufacture to the disposal and reuse of the members of the eaves gutter, CO2 is emitted. Therefore, for the eaves gutter to be constructed for one building, the greenhouse gas emissions such as CO2 corresponding to the number and size of the members constituting the eaves gutter will be generated. Considering such a situation, evaluating the greenhouse gas emissions (for example, LCCO2 (Life Cycle CO2) emissions) of the rain gutter constructed for a building leads to the understanding of the environmental performance of the eaves gutter (or rain gutter). Therefore, it can be said to be meaningful from the perspective of, for example, global environmental protection.

[0144] In calculating the greenhouse gas emissions corresponding to the construction of the eaves gutter, the storage unit 103 of the design and construction support device 100 may store emission information indicating the greenhouse gas emissions per unit quantity of the members of the eaves gutter, the greenhouse gas emissions for each gauge of the support tool, and the like. In the design and construction support device 100 of this modification example, the calculation unit 123 refers to the emission information, and obtains the greenhouse gas emissions of the eaves gutter corresponding to the length of the eaves gutter to be constructed input to the support tool usage determination sheet, and the greenhouse gas emissions corresponding to the breakdown of the number of support tools calculated corresponding to the eaves gutter. Thus, the greenhouse gas emissions corresponding to the construction of the eaves gutter may be calculated. The output unit 124 may display the calculated greenhouse gas emissions on the support tool usage determination sheet. Further, the output unit 124 may display the calculated greenhouse gas emissions on the support tool information output sheet. Note that the design and construction support device 100 may be configured to be able to calculate and output the greenhouse gas emissions of the rain gutter including the eaves gutter and the vertical gutter by including, for example, the greenhouse gas emissions corresponding to the members as the vertical gutter and the greenhouse gas emissions of the support tools for the vertical gutter in the price information.

[0145] [Sixth Modification Example] The calculation unit 123 of the design and construction support device 100 of each of the above embodiments may calculate the product weight corresponding to the construction of the eaves gutter. The calculated product weight may include the members as the eaves gutter and the supports corresponding to the number of support tools calculated corresponding to the eaves gutter. In calculating the product weight, the storage unit 103 of the design and construction support device 100 may store weight information indicating the weight of the members per unit length of the eaves gutter and the weight of the support tools for each thread count. The calculation unit 123 of the design and construction support device 100 may calculate the product weight corresponding to the construction of the eaves gutter by referring to the weight information to obtain the weight of the eaves gutter corresponding to the length of the eaves gutter to be constructed input to the support tool determination sheet and the weight corresponding to the breakdown of the number of support tools calculated corresponding to the eaves gutter. The output unit 124 may display the calculated product weight on the support tool determination sheet. Also, the output unit 124 may display the calculated product weight on the support tool information output sheet. Note that the design and construction support device 100 may be configured to be able to calculate and output the product weight corresponding to the overall construction of the rain gutter including the eaves gutter and the vertical gutter by including, for example, the weight corresponding to the members as the vertical gutter and the weight of the support tools for the vertical gutter in the price information.

[0146] [7th Modification Example] The calculation unit 123 of the design and construction support device 100 of each of the above embodiments may calculate the number of materials corresponding to the construction of the eaves gutter. The number of materials here may include the members as the eaves gutter and the supports corresponding to the number of support tools calculated corresponding to the eaves gutter. In calculating the number of materials, the storage unit 103 of the design and construction support device 100 may store dimension information indicating the dimensions of the members as the eaves gutter and the dimensions of the support tools for each thread count. The calculation unit 123 of the design and construction support device 100 may calculate the number of materials corresponding to the construction of the eaves gutter by referring to the dimension information to obtain the number of materials of the members of the eaves gutter to be used according to the length of the eaves gutter to be constructed input to the support tool determination sheet and the number of materials corresponding to the number of support tools used.

[0147] Furthermore, the calculation unit 123 may calculate the packing size of the materials required for the construction of the eaves based on the calculated number of materials. In this case, the storage unit 103 may store packing material size information indicating the size of the packing materials. The calculation unit 123 may calculate the size of the packing materials used for packing each of the eaves and the supports using the packing material size information, the number of materials for the eaves, and the number of materials for the supports. Furthermore, the calculation unit 123 may calculate the number of required packing materials. The output unit 124 may display the calculated size of the packing materials and the number of packing materials on the usage support tool determination sheet. Also, the output unit 124 may display the calculated size of the packing materials and the number of packing materials on the support tool information output sheet. Note that the design / construction support device 100 may be configured to be able to calculate and output the number of materials, the size and number of packing materials, etc. for the overall construction of the rain gutter including the eaves and the vertical members by including dimensions corresponding to members such as the vertical members as the eaves, dimensions of the supports for the eaves, etc. in the dimension information.

[0148] [Eighth Modification Example] In the design / construction support device 100, when the calculation unit 123 determines that it is impossible to install based on the length and slope of the eaves input to the input boxes BX4 (BX4-1, BX4-2) of the usage support tool determination sheet, the calculation unit 123 calculates the length, slope, and specification dimensions of the supports for which installation is possible, and the output unit 124 may display the calculated results in a predetermined manner on the usage support tool determination sheet.

[0149] Furthermore, when there are blank input items among the input items such as roof dimensions, eaves slope, eaves dimensions (height·width), and fitting dimensions on the usage support tool determination sheet or the building / support tool conformity determination sheet for which no numerical values have been input, the calculation unit 123 calculates the numerical values that enable installation by inputting to the blank input items, and the output unit 124 may display the calculated numerical values of the input items in a predetermined manner on the usage support tool determination sheet or the building / support tool conformity determination sheet.

[0150] [Ninth Modification Example] In each of the above embodiments, the type of roof to which the support is attached is not limited to a folded plate roof, and may be, for example, a corrugated slate roof, a tile bar roof, or the like. In addition, the attachment site on the building side to which the support is attached is not limited to the roof, and may be, for example, an outer wall of the building or the like.

[0151] [10th Modification Example] In each of the above embodiments, the compatibility determination between the support and the attachment site is performed for the eaves of the rain gutter, but the compatibility determination between the support and the attachment site may be performed for the vertical part of the rain gutter.

[0152] [11th Modification Example] The configuration of each of the above embodiments may be configured by communicably connecting a user terminal and a server on the network (such as a server device or a cloud server). In this case, the user terminal may access the server through a construction management application or a web browser so that an operation screen corresponding to the writing sheet is displayed. The user performs an input operation on the displayed operation screen. The server may execute processes such as determination and calculation similar to those of the design and construction support device 100 of each of the above embodiments in response to the input operation on the operation screen, and display the executed processing result on the operation screen. In this case, the functions in the control unit 102 and the storage unit 103 of FIG. 12 may be realized by a plurality of servers distributed on the network.

[0153] In addition, a program for realizing the functions of the above-described design and construction support device may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed to perform the processing as the above-described design and construction support device. Here, "reading and executing the program recorded on the recording medium by the computer system" includes installing the program in the computer system. The "computer system" as used herein is assumed to include hardware such as an OS and peripheral devices. Further, the "computer system" may include a plurality of computer devices connected via a network including a communication line such as the Internet, WAN, LAN, or dedicated line. Also, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, magneto-optical disk, ROM, CD-ROM, or a storage device such as an HDD or SSD built into the computer system. Thus, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. In addition, the recording medium includes an internal or external recording medium provided so as to be accessible from a distribution server for distributing the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program executable on the terminal device. That is, any form stored in the distribution server is acceptable as long as it can be downloaded from the distribution server and installed in a form executable on the terminal device. Note that the program may be divided into a plurality of parts, downloaded at different timings, and then combined on the terminal device, or the distribution servers for distributing the divided programs may be different.
