TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wall amount optimizing system for optimizing a load-bearing wall amount when designing a floor plan.
[0002]
[Prior art]
Building design is generally performed in the following procedure. First, the customer asks about the layout of the building. Create design drawings according to the determined layout. Next, the structural calculation of the building is performed according to the created design drawing. Through the structural calculation, it is determined whether or not the structural strength satisfies the structural strength stipulated by the Building Standards Act and the performance evaluation standards (hereinafter simply referred to as performance evaluation standards) based on the provisions of the Act on Ensuring Housing Quality. . Unless a sufficient amount of walls (bearing walls) having a certain strength are provided for external force due to wind and earthquake, the strength standards for wind pressure, earthquake vibration and impact are not satisfied. If each floor section separated by a load-bearing wall line with load-bearing walls does not have a certain strength or more, it will not meet the earthquake resistance standards. The required floor strength varies depending on the positions and intervals of the load-bearing wall lines. The strength of the floor is calculated from the number of reinforcing members called fire beams and the strength by a structural method such as a floor group.
[0003]
[Problems to be solved by the invention]
By the way, the conventional techniques as described above have the following problems to be solved.
When the floor plan of the building is discussed and its outline is determined, it is confirmed that the building satisfies the proof standard defined by the Building Standards Act and the performance evaluation standards as described above. If it is found out that the standard is not satisfied at that time, the floor plan will be discussed again. However, in order to determine whether or not the standard is satisfied, it is necessary to re-design each time. Therefore, studying the floor plan places a lot of burden on the designer. Also, if it is not possible to immediately judge whether or not the above criteria are met even if the floor plan is changed, the customer will also be required to make arrangements many times, and there will be a problem that it will take a very long time to determine the floor plan. .

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described using specific examples.
In the present invention, by analyzing the floor plan, the position of the load-bearing wall line and the floor magnification of each floor divided by the load-bearing wall line are obtained, and it is automatically determined whether the floor magnification of each floor satisfies a predetermined standard. And the result is displayed on the display. Further, when the type or layout of the wall is changed, the position of the load-bearing wall line is detected again, and the result is reflected in the determination. This enables a design that satisfies the required floor magnification on the spot while studying the floor plan.
[0010]
FIG. 1 is a functional block diagram of a computer for realizing the wall amount optimizing system of the present invention.
This computer is, for example, a personal computer or a workstation operated when a customer and a reporter in charge of design discuss a floor plan. A computer used for a meeting between a customer and a designer and a computer performing arithmetic processing with contents as shown in this figure are connected to each other via a network, and are configured to perform distributed processing. There is no problem. This computer is provided with hardware such as a display 1, a storage device 2, and an operation unit 4. The display 1 displays a floor plan or the like. The storage device 2 stores CAD data 3. The CAD data 3 is design drawing data for displaying a floor plan or the like. The operation unit 4 includes a keyboard 5, a mouse 6, and the like. Using this operation unit 4, the floor plan displayed on the display 1 is changed or corrected until the wall amount is optimized.
[0011]
The functional blocks such as the floor plan display means 7, the load-bearing wall line display means 8, and the comparison operation processing means 9 are composed of a computer program for causing a computer to execute a plan for a floor plan and a process of optimizing a wall amount. The existing floor magnification 11 and the required floor magnification 12 are data stored in a storage device of a computer for calculation processing. These may be included in the CAD data 3 together with the floor plan data, and may be extracted live as needed.
[0012]
FIG. 2 is an explanatory diagram illustrating an example of a floor plan displayed on a display.
The customer and the designer in charge determine an appropriate floor plan in advance, and the floor plan display means 7 displays the floor plan 20 on the display 1. The load-bearing wall line display means 8 detects all the load-bearing walls in the floor plan and accumulates the length of the load-bearing walls arranged on the same straight line. If the cumulative value of the length of the load-bearing wall is equal to or greater than the reference value, a straight line in which the load-bearing walls are arranged is set as a load-bearing wall line and displayed in the floor plan. In the example of FIG. 2, the load-bearing wall is displayed by a white frame, and the load-bearing wall line 21 is displayed by a dark solid line. At the end of the load-bearing wall line 21, the wall length K and the depth L are displayed side by side. The reason why the wall length K and the depth L of the load-bearing wall line are specifically displayed is to facilitate the review and optimization of the wall amount.
[0013]
The reference value is, for example, a case where bearing walls are arranged at least 60% of the length of the building in the linear direction. When a floor separated by the load-bearing wall line is called a floor section, an existing floor magnification is obtained for every floor section. The existing floor magnification is a design floor strength. In the figure, the horizontal display of each floor indicates that α is a coefficient for calculating the required floor magnification determined by the state of the load-bearing wall line, E is the required floor magnification for earthquake, W is the required floor magnification for wind, and A is the average floor magnification. It is.
[0014]
For example, in the case of a two-story building, the standard floor magnification determined by the specifications of the floor, the roof, and the stairwell is assigned to the existing floor magnification by looking at the state of the upper floor. If there are portions having different floor magnifications in one floor section, the average value of all floor magnifications is set as the existing floor magnification of this floor section. In this process, a standard floor strength is set for each part, and the existing floor magnification is calculated using the standard value. This is because the floor magnification can be checked even before the detailed structural design is determined. Next, the required floor magnification of the floor section is determined. The required floor magnification is a floor magnification that satisfies the standard defined by the performance evaluation standard of the quality assurance method. First, the required floor magnification for an earthquake is determined. Next, the required floor magnification for the wind is determined. Then, the larger value is adopted as the actual required floor magnification.
[0015]
FIG. 3 is an explanatory diagram of a floor plan example after the comparison operation processing means operates.
After obtaining the existing bed magnification and the required bed magnification, it is confirmed that the existing bed magnification is larger than the required bed magnification. When this condition is satisfied, it can be said that the floor plan during the design satisfies the standards defined by the Building Standards Act and the new performance evaluation standards. On the other hand, if this standard is not satisfied, the design must be reviewed by changing the position of the load-bearing wall or changing the layout. Therefore, in order to distinguish a floor section that does not satisfy the condition from other floor sections, for example, as shown in FIG. 3, the corresponding floor section 25 is hatched in the study direction. Review the design as follows. First, the space between the load-bearing wall lines 21 is reduced, and the area of the corresponding floor section 25 is reduced. If the area of the floor section becomes smaller, the required floor magnification becomes smaller.
[0016]
In order to reduce the interval between the load-bearing wall lines 21, there is a method of increasing the load-bearing wall line by adding a load-bearing wall to a portion where there was no load-bearing wall line. There is also a method of changing the position of the load-bearing wall line by changing the position of the load-bearing wall, which has been used so far. The required floor magnification can be reduced by matching the positions of the load-bearing wall lines on the upper and lower floors sandwiching the floor. Further, it is also possible to increase the existing floor magnification by increasing the design strength of the floor. Specifically, there is a method of increasing the amount of fire beams or changing the specifications of the floor. After changing the existing bed magnification or the required bed magnification, it is confirmed again that the existing bed magnification is larger than the required bed magnification. Repeat this to determine the optimal layout.
[0017]
FIG. 4 is an explanatory diagram showing an example of attribute data of a floor section displayed when a part of the floor section is changed from the standard floor magnification to increase the strength on the screen.
The screen 30 includes a display 31 of a floor covering and a display 32 of a magnification, a display 33 of a roof covering and a display of a magnification 34, a display 35 of a horizontal striking structure, and a display 36 of a magnification. A magnification display 37 is provided. From these, the existing floor magnification of the portion to be changed can be known. Further, a comparison display 38 of the average floor magnification and the required floor magnification in the X direction and the Y direction in the floor section including the changed portion and a display 39 of the comparison determination result are provided. In this way, for example, it is possible to change the attribute value of the floor section whose existing floor magnification is less than the required floor magnification by manual input, and to adjust so as to satisfy the condition.
[0018]
FIG. 5 is a flowchart showing a specific operation of the computer program.
First, in step S1, a floor plan is input, and the floor plan is displayed on the display 1 by the floor plan display means 7. When a start key (not shown) is clicked in step S2, the load-bearing wall line display means 8 is activated in step S3. It works and wall line selection is done. This wall line refers to all the lines on the floor plan where the wall exists. In step S4, the length of the bearing wall is accumulated on the first wall line. Next, in step S5, the length of the load-bearing wall is compared with the reference value, and if it is equal to or greater than the reference value, the load-bearing wall line is displayed in the manner already described.
[0019]
In the next step S6, it is determined whether or not selection has been completed for all wall lines. If there are remaining wall lines, the process returns to step S3. Thus, the processing from step S3 to step S6 is repeated. When the processing for all wall lines is completed, the process proceeds to step S7. In step S7, the comparison operation processing means 9 starts. Here, for all floor sections separated by the load bearing wall line, a comparison calculation process between the existing floor magnification and the required floor magnification is performed. When the first floor section is selected in step S7, the existing floor magnification and the required floor magnification are compared in step S8. If the existing floor magnification is smaller than the required floor magnification, the process proceeds from step S9 to step S10, and the corresponding floor section is hatched. In step S11, it is determined whether or not this calculation process has been completed for all floor sections. If not completed, the process returns to step S7 and the processes from step S7 to step S11 are repeated again.
[0020]
Through the processing from step S1 to step S11, the determination result for the floor plan input first is displayed. Based on the determination result, focusing on the portion where the existing floor magnification is insufficient, performing processing such as moving the load-bearing wall line, changing the floor plan, increasing the load-bearing wall, or changing the floor strength. . The result is input to the computer again. Then, the processing from step S1 to step S11 is executed again. Since the calculation processing by the computer is performed at an extremely high speed, it is not a great burden for the person in charge of designing the floor plan and optimizing the floor plan and the amount of wall by making appropriate corrections if the standard is not satisfied. Moreover, if the standard floor strength is set for each part and the existing floor magnification is calculated based on the value of the standard floor strength, the floor magnification can be checked without performing a structural design. is there. Therefore, it is possible to solve the conventional problem that the structural design is performed in accordance with the layout arrangement and the layout arrangement must be performed again when the wall amount is insufficient.
[0021]
FIG. 6 is an explanatory diagram showing a specific modification example of the display method of the wall amount.
In the above example, the wall length K and the depth L of the load-bearing wall line are displayed numerically along each wall line. However, when calculating the wall amount, it is required to confirm the total wall length in each of the X direction and the Y direction. Therefore, a graph space is provided on the side of the screen 50 as shown in the figure. The length of the bar 52 corresponds to the total wall length in the Y direction. The value was displayed as “the amount of existing wall”. 31.40 indicates the wall length of the load-bearing wall in units of meters (m). In addition, in this graph space, three types of indices 53, 54, and 55 of grade 2, grade 3, and (standard method × safety factor) are shown. Each level for multiple evaluation criteria, such as whether the wall length of the load-bearing wall exceeds grade 2, exceeds grade 3, and meets all the criteria of the standard method considering the safety factor of the company standard It can be evaluated simultaneously in this graph space. In this example, only the graph space for displaying the total wall amount in the Y direction is shown, but the same applies to the X direction.
[0022]
As described above, a predetermined amount of data is displayed on the graph space formed in a strip shape at the periphery of the display screen using the length of the bar extending in the longitudinal direction of the graph space, and the data amount is displayed on the graph space. By displaying a plurality of indices to be compared with, important data such as wall length can be displayed clearly and easily using a very narrow space. That is, with such display, while the load-bearing wall amount is increased or decreased, the wall amount can be optimized and the floor magnification setting can be adjusted in parallel. Each functional block shown in the figure may be configured by a separate program module, or may be configured by an integrated program module. Further, all or a part of these functional blocks may be configured by hardware using a logic circuit. Further, each program module may be operated by being incorporated in an existing application program, or may be operated as an independent program. The computer program for implementing the present invention as described above can be recorded on a computer-readable recording medium such as a CD-ROM, installed, and used. It can also be used by downloading it to the memory of a computer via a network.
