Is done. These databases 8 and 9 are provided in a data management center, and a designer accesses the center using information communication means such as a LAN, or reads a recording medium on which data is recorded on a personal computer. Thus, the designer can use it arbitrarily.

Next, the portal ramen used in the present invention will be described. FIG. 3 is a perspective view showing the structure of the portal ramen 10 used in the present invention. The portal ramen 10 includes a pair of column members 11 and 11 'having a solid structure and a beam member 12 connected to the inside of the upper end portion thereof. Grooves are formed on the upper and lower surfaces of both ends of the beam member 12, hole-down fittings 14 are attached to the grooves, and hexagon bolts 15 are passed through the column members 11, 11 'from the outside to form the hole-down fittings 14. Screw on. The beam member 12 has a configuration in which a pair of satiety beams are attached to both side surfaces of a pair of frame members that extend parallel in the vertical direction, and intermediate pillars that connect the upper and lower frame members are provided at predetermined intervals in the middle part of the frame member. . In addition, since the detailed structure and effect of the portal ramen 10 are described in Japanese Patent Application No. 2003-367510 by the present applicant, detailed description is omitted here.
The portal ramen 10 having such a structure is used for a portion having an opening of a wooden building. However, the opening of a wooden building has various sizes depending on its structure. However, since the size of each part of a wooden building such as a normal house is defined by the metric method or the shank method, the size of the portal ramen 10 can be integrated into a certain number of standard frames.

The standard frame is set as follows.
(1) Height of pillar members 11 and 11 'The height of the pillar members 11 and 11' is based on the height of a three-story eave height of 9m according to the Building Standard Law. The height of the pillar 11 is 3000 mm, and the height of the pillar 11 of the portal ramen 10 for the second and third floors is 2730 mm.
(2) Spacing (span) between the pair of column members 11, 11 ′
The distance between the pair of column members 11, 11 ′ (hereinafter referred to as “span”) is determined according to the width of the wall surface having the opening, and is 4000 mm, 4500 mm, 5000 mm, 5500 mm, 6000 mm, 6500 mm, 7000 mm, 7500 mm, and 8000 mm. Nine types are prepared.
(3) Width and height of beam member 12 (beam back)
The beam member 12 includes a BB (B) type in which the upper and lower frame members of the satiety beam are made of a laminated material having a width of 120 mm and a height of 150 mm, an upper frame member having a width of 120 mm × height of 360 mm, and a lower frame member having a width of 120 mm. X Two types of BB (A) type composed of a laminated material having a height of 150 mm are prepared, and the height between the upper end of the upper frame member and the lower end of the lower frame member (hereinafter referred to as the beam back) is BB ( For the A) type, four types of 650 mm, 750 mm, 850 mm and 950 mm are prepared, and for the BB (B) type, five types of 550 mm, 650 mm, 750 mm, 850 mm and 950 mm are prepared. In addition, these are all for the outer peripheral portion where the installation position hits the corner of the building, and for the intermediate portion, the beam back is raised by 500 mm.
Among these combinations, when the beam back is selected to be 1/10 or less of the span, and the one that can secure the opening height under the beam of 1980 mm or more is selected, 82 types whose numerical values are shown in FIG. become. These 82 types are set as the standard frame of the portal ramen in the present invention. With regard to the standard frames of 82 types of portal ramen, the allowable strength is calculated in advance and stored in the portal ramen database 8 in FIG. The numerical value in FIG. 4 is the allowable strength (unit is kN) of each standard frame.

Next, a method for designing a building using the portal ramen 10 as described above will be described. In the following description, a method for newly building a building will be described as an example, but the method is basically the same for extension and reconstruction.
Referring to the flowchart of FIG. 1, first, in step 1, plan view data of a newly built building is created, input, and stored in the storage means in the CAD software 5. FIG. 5 shows an example of the plan view 20 of the one-story house input. The input of the plan view is performed by reading out data created in advance by the CAD software 5 installed in the personal computer 1 or by directly writing in the personal computer 1 using the input device 2. Alternatively, the drawing may be made on paper and read by the scanner 4. The plan view 20 input to the personal computer 1 is displayed on the display means (screen) of the personal computer 1.
Next, in step 2, in the plan view 20 displayed on the display means of the personal computer 1, the position for installing the portal ramen 10 is designated. In this operation, the CAD software 5 detects the opening from the indoor space and the wall surface partitioning the indoor space from the data of the plan view 20, and displays the color of the opening and both sides thereof in a color display or blinking manner. The input device 2 such as a mouse is appropriately designated from the outer wall portion and a position extending from the outer wall portion in a direction orthogonal to the inside. In FIG. 5, for example, it is specified that the portal ramens 31, 32, 33, and 34 are installed so as to surround four sides of the space composed of the living room 21 and the Japanese-style room 22. The openings of the two portal ramens 31 and 32 along the outer wall correspond to the windows of the living room 21 and the Japanese-style room 22, and the openings of the two portal ramen structures 33 and 34 in the room are the living room 21 and the kitchen 23. Corresponding to a passage with another room such as the dining room 24, an opening facing the closet 25, the space 26 between the floors, and the like.

Next, in step 3, the data of the portal ramens 31, 32, 33, 34 at the position specified in step 2 is acquired. In step 3, when the position is designated in step 2, the designated position information is read by the CAD software 5, and the data of the portal ramens 31, 32, 33, and 34 most suitable for the position and its dimensions are obtained. It is read from the standard frames of 82 types of portal ramen stored in the portal ramen database 8. That is, for the floor number data of the building and the installation position data for the outer or middle part, select the corresponding one, and for the span data, if there is no match, select the one with the closest span width . Specifically, the portal ramen 31 is for the outer wall of the living room 21 and has an opening of 4500 mm. Therefore, from the data in FIG. 4, the floor height H for the first floor is 3000 mm and the span L is 4500 mm. BB (B) 550 is read and displayed on the display means of the personal computer 1. Similarly, the portal ramen 32 is for the outer wall of the living room 21 and the Japanese-style room 22 and has an opening of 7000 mm. Therefore, a BB (B) 750 having a floor height H = 3000 mm and a span L = 7000 mm for the first floor is The ramen 33 is for the interior that constitutes a passage part between the living room 21 and other rooms such as the kitchen 23 and the dining room 24, and has an opening of 7000 mm. Therefore, the floor height H for the first floor is H = 3000 mm, the span L is 7000 mm, BB (B) 800 having a beam back 500 mm larger, the portal ramen 34 has an opening facing the Japanese-style room 22 and the closet 25, the space 26 between the floors, etc., and the opening is 4500 mm. BB (B) 600 with 3000 mm, span L = 4500 mm, and beam back 500 mm larger is read as corresponding data. Alternatively, the position information data may be manually input, and the portal ramens 31, 32, 33, and 34 that match the position may be read from the portal ramen database 6 based on the input data.
Next, in step 4, the difference between the span of each of the portal ramens 31, 32, 33, 34 read from the portal ramen database 6 in step 3 and the length at the corresponding location in the plan view is corrected. A plan view 20 based on the dimensions of the portal ramen is created. The plan view 20 in FIG. 5 is not corrected because the spans of the respective portal ramens 31, 32, 33, and 34 and the lengths of the corresponding portions in the plan view 20 are the same. If the span of the portal ramens 32 and 33 read and input from the database 8 is different from the length of the plan view 20, the difference is moved between the living room 21 and the outer wall on the kitchen 23 side, that is, the adjacent indoor space. The plan view 20 is corrected by changing the areas of the living room 21 and the kitchen 23. This correction is automatically performed by correction software incorporated in the CAD software 5 in advance, or manually by the designer using the input device 2.
When the portal ramen data is taken in and corrected in the plan view 20 in this way, it is confirmed in step 5, and if it is determined to be good, the process proceeds to step 6. If the modification of the plan view 20 does not like the designer or the client in step 5, the process returns to one of steps 2 to 4 and the operations from the step are repeated.
If the result of the confirmation in step 5 is satisfactory, the process proceeds to step 6 where the allowable proof stress of each of the portal ramens 31, 32, 33, 34 is converted into a wall magnification, and in step 7, the structure of the entire building is calculated. In addition, in the structural calculation of the entire building, the wall magnification is determined by the position and shape of each unit wall of the wall other than the portal ramen, that is, the wall forming the outer wall of the building and the inner partition. These wall magnification targets are obtained by acquiring the position information indicating the positions of the pillars and horizontal members, the wall material existing between the pillars and the size information of the openings with the CAD software 5 from the plan view 20 data. It is determined whether it corresponds to a semi-bearing wall or other wall, and the wall amount of each determined wall is calculated. Further, not only the structural calculation based on the wall magnification but also the building balance is performed by converting the allowable proof strength of each of the portal ramens 31, 32, 33, and 34 into the wall magnification. The building balance is performed by adding the wall magnifications of the respective walls on the coordinate axes XY, and comparing the distance between the rigid position on the coordinate axes and the center of gravity position of the building based on the calculated distance.
As a result of the structural calculation in step 7, it is determined in step 8 whether the building standard method and the predetermined seismic performance are satisfied. If the determination result is acceptable, the design is completed. If the determination result is unacceptable, the process returns to one of steps 2 to 4 and the work from the step is repeated. Conversion to wall magnification, structural calculation of the entire building, and result determination of the structural calculation are performed by the structural calculation software 6.

  In the above description, the one-story building in FIG. 5 has been described as an example. However, a two-story or three-story building can be designed in the same manner. In the case of a two-story or three-story building, the selection of the portal ramen in step 3 is performed by selecting the first floor part from the group of the first floor height H = 3000 mm in FIG. 4 and the second and third floor parts in FIG. Are selected from the group of floor height H = 2730 mm for the second and third floors. Other steps are the same.

FIG. 6 is a flowchart showing the flow of the building estimation method in the present embodiment. Step 11 and subsequent steps in FIG. 6 are performed when the determination result in step 8 in FIG. 1 is acceptable. When the determination result of step 8 in FIG. 1 passes and the design is completed, the process proceeds to the required cost estimation calculation in FIG.
In step 11, the materials of the portal ramens 31, 32, 33, 34 selected in step 3 of FIG. 1, materials such as joining members and fittings, and portal ramen member data such as unit prices from the construction database 9. take in. FIG. 7 shows an example of portal ramen member data.
In step 12, data such as the man-hours, time and unit price required for the construction of the portal ramens 31, 32, 33, 34 are taken from the construction database 9.
In step 13, construction is performed based on the portal ramen 31, 32, 33, 34 data acquired in step 11 and the portal ramen construction data required for the construction of portal ramen 31, 32, 33, 34 acquired in step 12. Calculate the amount of money needed for.
In step 14, the result calculated in step 13 is created in the form of a predetermined estimate and stored in the hard disk or external memory of the personal computer 1.
Each operation of step 11 to step 14 is executed by the estimation calculation software 7.
In step 15, the estimate prepared in step 14 is supplied to the output device 3 and printed by a printer.

FIG. 8 is a block diagram illustrating an example of a hardware configuration for executing the building design method according to the present embodiment.
The operation of the hardware configuration in FIG. 8 will be described below with reference to the flowchart of FIG.
First, a plan view 20 of a building created in advance by the scanner 4 is read (step 1), and an opening in the input plan view 20 is detected by the opening detection unit 41. Since the portal ramen used in the present invention is installed in an opening of a building, the detection of the opening corresponds to setting a position candidate for installing the portal ramen.
Next, the position data of the opening detected by the opening detection unit 41 by the opening specifying unit 42 is compared with the position data stored in the portal ramen position selection database 43, and an opening having a substantially matching position is selected. And specify the position to install the portal ramen. That is, the portal ramen position selection database 43 stores the condition data by pre-selecting a position where it is preferable to install the portal ramen for the building in consideration of the Building Standard Law and the like. By selecting a position where the condition data and the condition data of the opening detected by the opening detection unit 41 match or approximate, the position where the portal ramen is to be installed is designated (step 2).
Next, the comparison / selection unit 44 compares the position data specified by the opening specifying unit 42 with the standard frame data of 82 types of portal ramen stored in the portal ramen database 8 to specify the opening. The standard frame of the portal ramen that best matches the position data specified by the unit 42 is selected (step 3).
Next, in the plan view correcting unit 45, based on the size of the portal ramen so as to correct the difference between the span of the standard frame of the portal ramen selected by the comparison / selection unit 44 and the length at the corresponding portion of the plan view. A plan view 20 is created (step 4).
The plan view corrected by the plan view correction unit 45 is confirmed in step 5, and if it is determined to be good, the process proceeds to step 6. If the modification of the plan view 20 does not like the designer or the client in step 5, the process returns to one of steps 2 to 4 and the operations from the step are repeated.
If the confirmation result of step 5 is satisfactory, the wall magnification conversion unit 46 converts the allowable proof strength of each portal ramen into the wall magnification based on the plan view corrected by the plan view correction unit 45 (step 6), and further the structure. The calculation unit 47 calculates the structure of the entire building (step 7).
The structural calculation result calculated by the structural calculation unit 47 is compared with various data and seismic performance data based on the building standard method stored in the building standard method database 49 by the comparison unit 48, and the result is determined ( Step 8) is displayed on the display unit 50.

In the above description, the member data and the construction data of the portal ramen are acquired in step 11 and step 12, and the case where the estimated amount of only the portion using the portal ramen is calculated in step 13 is explained. The data other than the portal ramen use part of the building is accumulated in 9, and a step of acquiring those data is added before step 13, and an estimate required for construction of the entire building is created in step 13 It is also possible.
In this case, if Step 11 and Step 12 are omitted, it is possible to create an estimate of the building without using the portal ramen, so create comparison data of the estimated amounts with and without using the portal ramen. can do. Therefore, the client can be presented with a comparison of the estimated amounts of both.
In addition, if you create the comparison data of earthquake resistance and strength by the design using the portal ramen method described in this example and the conventional design that does not use the portal ramen, and present it together with the comparison data of the estimated amount, the client The superiority of the portal ramen method according to the present invention can be explained sufficiently.
