Abstract

PURPOSE:To enable even an unskilled engineer to effectively perform the final design by inputting the design conditions via the selection of items carried out through a sheet and the key operations on a keyboard and calculating the product performance to decide the propriety of this performance. CONSTITUTION:The intensity of an external panel is calculated by setting a sheet on a tablet 11. The type, the material, the structure, etc., of the panel are inputted by pointing the corresponding sections in the sheet with use of a stylus pen 12. Then the size of the panel is inputted via a keyboard 13 together with the value of the coefficient of wind force and the panel attachment conditions including the panel attachment height, etc. Then the sectional size of an area where the intensity is calculated is inputted. Thus a CPU 2 displays the allowable stress and the allowable flexion on a display device 3 and decides whether the result of calculation exceeds the allowable value or not to inform an operator of this deciding result. Thus the designing operations can be repeated with change of the designing conditions and the optimum design is effectively attained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method of examining product specifications for exterior panel building materials, and relates to a structural calculation device that facilitates the examination of strength against wind pressure to 1%.

(Prior art) Conventionally, in this type of wind pressure strength calculation method, the wind pressure to which the exterior panel building material is subjected is calculated based on the Building Standards Act, etc., and the cross-sectional performance (2 Calculations of dimensional moments, etc.) as well as stress and deflection values, which are required in consideration of materials and other factors, are all done manually. Moreover, in order to determine whether the performance of a product is appropriate based on the calculation results, searching for calculation formulas and judging the calculation results are all done manually, making it difficult for architectural design professionals who require these calculations.
This was an impediment to making the industry more efficient.

(Problem to be solved by the invention) In the conventional method for calculating the wind pressure strength of exterior panel building materials, the calculation formula and constants necessary for calculation are manually searched, and calculations and judgments are difficult. Work is also manual.

Therefore, one task takes a long time and there are many calculation errors.
The drawback is that it can only be done by experienced people.

Therefore, it was not possible to conduct a sufficient specification study.

The drawback is that it reduces the efficiency of the design.

An object of the present invention is to suitably select the pattern of exterior panel building materials displayed as a picture on the display device, automatically select the shape, calculation formula, and various constants according to instructions from the display device. This is an exterior panel construction material that eliminates the above drawbacks by automatically calculating the strength just by inputting the condition values and determining whether it is appropriate or not, so that even non-experts can efficiently perform it. The purpose of the present invention is to provide a wind pressure strength calculation device.

(Means for Solving the Problems) A wind pressure strength calculation device for exterior panel building materials according to the present invention includes a central processing unit, an auxiliary storage device, an input device, and a display device.

The central processing unit is for calculating and determining the wind pressure strength of the exterior panel building material when a calculation pattern or parameter is selected interactively, and displaying the result on the display device.

The auxiliary storage device is for storing information regarding exterior panel building materials and their calculations and formulas, as well as information necessary for calculations. 2. A human powered device is a device for inputting instructions by operating keys and an indicator pen.

The display device is for displaying operating conditions and calculation results according to the calculation results of the central processing unit.

(Example> Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a wind pressure strength calculation device for exterior panel building materials according to the present invention.

In FIG. 1, l is an input device, 2 is a central processing unit, and 3 is an input device.
1 is an auxiliary storage device, 11 is a tablet, 12 is a stylus pen, and 13 is a keyboard.

The input device l consists of a tablet 11, a stylus pen 12, and a keyboard 13. A sheet divided into several items is placed on the tablet 1, and information can be input to the central processing unit 2 by pointing to an appropriate section on the sheet with the stylus pen 12. Based on the input information, the central processing unit 2 performs calculation processing using each draft data and calculation formula stored in the auxiliary storage device 4, and displays the results on the display device 3 together with the input information.

In calculating the strength of the exterior panel, a sheet as shown in FIG. 2 is placed on the tablet 11. The type, material, structure, etc. of the panel on which the calculation is to be performed can be entered by using the stylus pen 12t to indicate the corresponding section in the sheet.

Next, when the dimensions of the panel are input from the keyboard 13, the central processing unit 2 calculates the area of the party wind section and displays it on the display device 3.
Shown above. Next, when the wind force coefficient value and the panel installation conditions such as the height of the panel are input, the central processing unit 2 calculates the wind pressure and the load applied to the panel according to the building standards, etc., and displays it on the display device 3. do.

Next, when the cross-sectional dimensions of the part whose strength is to be calculated are input,
Based on this, the central processing unit 2 calculates the second moment of inertia and section modulus of the section C, and calculates the bending moment, stress, and deflection in conjunction with the previously calculated load.
The results are displayed on the display device 3. The central processing unit 2 simultaneously displays the allowable stress and allowable deflection t on the display device fii3, determines whether the calculated result exceeds the allowable value, and notifies the operator.

FIG. 3 is an explanatory diagram showing an example of a display when calculation processing is completed.

In addition to the above explanation, it is also possible to calculate a cross-sectional dimension that satisfies the allowable stress and allowable deflection by changing the purpose of calculation.
