[0011]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, in the present embodiment, for example, a notebook personal computer 1 (computer)
The personal computer 1 includes an input unit 4 composed of a keyboard 2 and a mouse 3 and a display unit 5 composed of a liquid crystal display or the like. Is built-in, and is connected to a printing device (not shown) so that various data such as input images can be printed. In carrying out the present invention, a so-called desktop personal computer or the like may be used instead of the notebook personal computer 1.

The storage unit of the personal computer 1 previously stores a floor plan input display program for inputting the floor plan of each floor of the house on the display unit 5 in a predetermined input procedure. Further, the storage unit stores a conversion program for converting each member (outer wall, beam, column, etc.) in the input plan into three-dimensional coordinate data, and performs a structural calculation based on the coordinate data. A structural calculation program to be performed is stored. The various programs are recorded on one or more floppy disks F (recording medium), for example.
The floppy disk F can be installed in the storage unit of the personal computer 1. Note that a CDROM or the like may be used as the recording medium.

Next, a method of creating a floor plan of each floor of a house while displaying it on the display unit 5 of the personal computer 1, particularly a procedure of inputting a plane shape of a beam in the floor plan will be described. When starting the creation of a floor plan, after setting in advance how many floors the house will be, and specifying a desired floor, for example, the second floor, as shown in FIG. An input screen A for creating a floor plan of the floor is displayed on the display unit 5. The upper part of the input screen A forms an operation button display area A1 for displaying various buttons C for input operation,
An area extending from the center to the lower part of the input screen A forms an image display area A2 for displaying an image such as a plan.

In the image display area A2, for example, the size of a house 5
Guide lines 6 are displayed vertically and horizontally at intervals corresponding to m, large dots 7 are displayed at intervals corresponding to 1 m of the house, and small dots 8 are displayed at intervals corresponding to 0.25 m. Note that the intervals between the guide lines 6, the large dots 7, and the small dots 8 can be appropriately set, and changes such as omitting the display of the guide lines 6 can be arbitrarily made.

When creating a floor plan on the image display area A2, a cursor (not shown) is moved to a button C corresponding to a member to be input among various buttons C in the operation button display area A1, and the left mouse button The button 3a is clicked (hereinafter, the operation of clicking the left button 3a of the mouse 3 is simply referred to as clicking). For example, when inputting a beam, when the beam button C1 is clicked, a member name “beam” is displayed on the member display section D1, as shown in FIG. 3, and subsequently, a selection button Cs for selecting the type of beam. When you click, the name corresponding to the type of beam “G1, G3, B1, B3, B4 ...
.. ", And a display area F displaying the cross-sectional shape and cross-sectional dimension of each beam appears.

Here, "G" beams ("G1", "G3")
And the "B" beams ("B1,""B3,""B4") are made of H-section steel. “G1” and “B1” have the same cross-sectional dimensions,
Both 250 (web width) x 125 (flange width) x
6 (web thickness) x 9 (flange thickness) (all units are mm). “G3” and “B3” have the same cross-sectional dimensions, and both are 250 × 125 × 4.5 × 6. Further, the cross-sectional dimension of “B4” is 250 × 125 × 3.2 ×
4.5. The “G” beam is friction-bonded to other members (other beams and the like) using high-strength bolts, while the “B” beam is connected in a normal connection form and has the same cross-sectional dimension.
In terms of strength, the “G” beam is stronger than the “B” beam.

Also, "E" beams ("E1", "E2")
Is used as a windproof beam or the like, and has a larger cross-sectional dimension than the “G” beam and the “B” beam. “J1” and “J2” are beam connections and have smaller cross-sectional dimensions than “G” beams and “B” beams. Although the automatic selection of the beam size will be described later, the personal computer 1 determines the type of the beam from the “G” beam or the “B” beam according to the use position of the beam or the connection relationship with other members. Is a mode in which is automatically selected.

For example, when the input operator selects and inputs a beam of type "G1", the cursor is moved to "G1" and clicked, as shown in FIG. 4, the name "G1" is displayed on the type display section D2. Is displayed, and in this state, the beam of the type “G1” can be input. When inputting, first, the cursor is placed on the starting point S1 of the beam to be input and clicked, and the personal computer 1 recognizes and stores the starting point S1.
Here, the large dot 7 or the small dot 8 closest to the cursor at the time of clicking is selected as the start point S1.

Subsequently, when the cursor is moved vertically or horizontally in the direction of the end point of the beam by operating the mouse 3, the direction in which the beam extends along the straight line L in the image display area A2 as shown in FIG. Is displayed. In this case, the direction in which the beam extends is displayed as a vertical or horizontal straight line L based on the start point S1 even if the cursor slightly meanders due to the operation of the mouse 3.

Then, when the cursor reaches the end point S2 of the beam, when the beam is clicked again, the beam 10 is formed as a rectangular image having a predetermined width instead of deleting the straight line L as shown in FIG. The name “G1” is displayed and indicates the type of the beam 10. As described above, in the present embodiment, the type of the beam 10 is selected, and the start point S1 and the end point S1 are selected.
By simply clicking two points 2, a rectangular image representing the planar shape of the beam 10 is created and displayed in the image display area A2. As can be seen from FIG. 6, both end positions of the beam 10 displayed on the display unit 5 correspond to the start point S1 and the end point S2.
The beam 10 is positioned slightly inside, so that the length of the beam 10 is slightly shorter than the distance between the start point S1 and the end point S2.
The length of 0 is determined.

Thereafter, in the same manner as above, the type of the beam 10 or the beam joint 11 is selected in the display area F of FIG. 3, and the two points of the starting point and the ending point are sequentially clicked and input. Image data representing 10 or the beam joint 11 is stored in the storage unit of the personal computer 1 and displayed in the image display area A2 as shown in FIG. In this case, the individual beams 10 or the beam joints 11 are displayed at a substantially fixed scale, so that the “E” beam (“E1”, “E2”) is displayed wider than the “G” beam or the “B” beam. On the other hand, the beam connection “J1” and “J2” are displayed to be narrower than the “G” beam and the “B” beam.

In the present embodiment, the individual beams 1
Since the ends of the beams displayed on the display unit 5 are located slightly inside from the start point S1 and the end point S2 of 0, for example, as shown in FIG. When two beams 10 orthogonal to each other (for example, both types “G1”) are sequentially input, even if the starting points S1 of both beams 10 at the time of input are both located in the corner portion X, the display portion 5 Are not occupying the corner portion X.

Therefore, when it is desired to set the connection relationship of any one of the beams 10, for example, the beam 10 extending in the lateral direction in the figure, so as to occupy the corner X, one end of the beam 10 in the lateral direction is required. By designating 10a, the display is switched so that the beam 10 occupies the corner portion X as shown in FIG.

Here, the beam 10 on the side occupying the corner portion X
Is specified, for example, after clicking the material end button Ce in the operation button display area A1, the one end 1
By placing the cursor on 0a and clicking, the display is switched so that the one end 10a occupies the corner X as shown in FIG. Thereby, the beam 10 on the side occupying the corner portion X (referred to as a winning beam) and the beam 10 on the side not occupying the corner portion X (referred to as a losing beam) can be easily selected.

The input beam 10 is displayed in the image display area A2.
When deleting from the personal computer 1, the cursor is positioned on the delete button C2 in the operation button display area A1 and clicked. Then, the cursor is positioned on the beam 10 to be deleted and clicked once again. The image representing the beam 10 is deleted from the storage unit and is deleted from the image display area A2.

Although not described in detail here, various members such as columns and outer walls are selected by the corresponding buttons C in the operation button display area A1 in addition to the beams 10 and the beam joints 11 when an actual plan is created. The various members are input to the image display area A2 by a predetermined input method. After the construction of the 2nd floor plan is completed,
When there is a floor above the third floor, subsequently, the floor button C3 in the operation button display area A1 is clicked, and the floor above the third floor is sequentially designated to create a floor plan for each floor of the house.

In the floor plan of the first floor, a base beam (beam) is input instead of the beam 10 or the beam joint 11 described above. As shown in FIG. 10, when inputting the foundation beam, clicking the foundation beam button C4 causes the member display section D to be displayed.
1 displays a member name “foundation beam”, and subsequently, when the selection button Cs is clicked, a plurality of names indicating the type of foundation beam are displayed in the display area F. Although the type of the foundation beam is not described in detail, here, it is assumed that a standard reinforcing bar is selected and input.

As shown in FIG. 11, at the time of inputting the foundation beam, as in the case of the beam 10, clicking on the start point S1 and the end point S2 on the image display area A2 causes the start point S1 and the end point S2 to be clicked. The image data of the foundation beam to be inputted is created by the personal computer 1 according to the type of the foundation beam and the type of the foundation beam.
Based on this image data, the foundation beam 1 is placed in the image display area A2.
The two rectangular planar shapes are displayed. Here, beam 10
Unlike the case of (1), the end 12a of the foundation beam 12 is set slightly outside the start point S1 and the end point S2, and
The length of 2 is slightly longer than the distance between the start point S1 and the end point S2.

In the present embodiment, it is considered that the data on the foundation (cloth foundation) is also inputted along with the input of the foundation beam 12, and the foundation 13 is displayed around the foundation beam 12 by a dotted line. . The width of the base 13 can be selected from a plurality of types. When the width of the foundation 13 is selected, as shown in FIG.
1 displays “cloth base width”, and in this state the selection button C
When s is clicked, a plurality of base widths (standard is 590 mm) are displayed in the display area F, and a desired base width may be selected by clicking the desired base width. FIG. 13 illustrates a case where a foundation beam 12 is input by selecting a foundation width other than the standard, for example, 1100 mm.

FIG. 14 shows a state in which a plurality of vertical and horizontal foundation beams 12 are input at a standard foundation width by clicking the start point and the end point as described above. Here, beam 1
Unlike the case of 0, even if the processing by the material end button Ce is not performed, the corner beams X are displayed in a state where the ends of the vertical and horizontal foundation beams 12 overlap each other. In addition, the foundation beam 12 and the foundation 1
When part of part 3 is desired to be lowered, clicking down button C6 displays "foundation beam part down" in member display portion D1, and in this state, clicking selection button Cs causes display of foundation beam 12 in display area F. The down amount (unit: mm) is displayed. Here, for example, 300 mm is selected, and in FIG. 15, when the start point T1 and the end point T2 of the area for lowering the foundation beam 12 and the foundation 13 are sequentially clicked, the down area 14 of the foundation beam 12 and the foundation 13 becomes a rectangular mark. Is displayed with.

When the creation of the floor plan for all floors is completed,
When the structural calculation is performed, when the structural calculation is instructed to the personal computer 1, each of the members graphically input in the above-described plan is converted into coordinate data by the conversion program, and subsequently, based on the coordinate data, The structural calculation is executed by the structural calculation program. As a result of the structural calculation, if any of the members is determined to have insufficient strength, the plan is changed in order to reinforce the member or its peripheral portion.

For example, when it is determined that one of the beams 10 has insufficient strength, the beam 10 is deleted by the above-described method and replaced with a beam 10 of higher strength, or After making changes such as increasing the number of beams in the peripheral portion where the insufficient beam 10 is located, the above-described structural calculation is performed again.

Next, the case where the above-mentioned automatic beam selection mode is used will be described. When the automatic selection of the beam type is performed, when the automatic selection is selected in the display area F of FIG.
As shown in the figure, "automatic selection" is displayed on the type display section D2. In this state, the start point S1 and the end point S1
When 2 is input, a graphic representing the beam 10 is displayed on the display unit 5 as described above.

This automatic selection is based on the “G” beam (“G1”,
“G3”) and “B” beams (“B1”, “B3”, “B”)
4)), a predetermined selection rule is stored in the storage unit incorporated in the personal computer 1, and when the input operator selects the automatic selection mode, the input position of the beam and other members are determined. The personal computer 1 automatically selects any one of the "G" beam and the "B" beam based on the above selection rule in accordance with the connection relationship of the above. In the case of automatic selection, as described later, the initially selected beam may be replaced by another beam depending on the result of the structural calculation. Therefore, the name indicating the type of beam is as shown in FIG. In the beginning, simply "G"
(Or “B”) only, or the name is not displayed until the type of beam is finally determined.

Here, an example of the above selection rule will be described. The initial setting for automatic selection is "B4", and the size is increased under the following conditions. That is, the beam receiving the outer wall is "B3". The beam to which the supporting column (column made of square steel) is connected is "G
3 ". The beam to which the ramen columns (columns made of H-section steel) are joined is referred to as “G1”. The wind resistant beam is “G1”. Here, a stairwell with a stairwell facing the perimeter of the house and a beam having a length exceeding 2.5 m is regarded as a windproof beam. The beam that does not correspond to any of the above-mentioned items is "B4" of the initial setting.

In the case of using the automatic beam selection mode, after the creation of the plan, when the personal computer 1 performs the structural calculation,
If any of the automatically selected beams is determined to have insufficient strength or the like, the automatically selected beams are automatically sized up under the following conditions, and the structural calculation is performed again after the sizing. That is,

As a result of the stress analysis by the structural calculation, the beam determined to contribute to the stress transmission of the support column is increased in size to “G3”. Here, the beam that contributes to the stress transmission of the support column is defined as a beam in which a unit vertical load is applied to all the nodes attached to the support column, and the stress transmission rate is 10% or more.

As a result of the stress analysis by the structural calculation, the beam determined to contribute to the rigid frame is increased in size to “G3”. Here, the beam that contributes to the rigid frame is defined as a beam that generates a bending stress in a strong axial direction when a horizontal load is applied.

The beam determined to be insufficient in strength as a result of the cross-sectional verification by the structural calculation is “B4” for the “B” beam.
The size is increased in the order of “B3” → “B1”, and the size of the “G” beam is increased in the order of “G3” → “G1”. However, the size increase over “B1” and “G1” is not performed. When actually inputting beams, the input operator may select the beam type for some beams and use the automatic selection mode for the remaining beams. In addition, the automatic selection of the foundation beam 12 is not normally performed.
