Description

The present invention relates to a check sheet for calculating the structure of a wooden building, mainly to obtain the owner's opinion regarding the structural strength.

In structural calculations for wooden buildings, numerical information on strength calculation elements such as seismic performance, wind resistance, and load-bearing performance is introduced into the calculation formula, and based on the obtained results, for example, columns and Determine the type and necessity of materials such as the diameter of structural materials such as beams and bundles, the thickness of load-bearing walls, and the presence or absence of load-bearing walls. Patent Document 1 is cited as an example of a technique related to structural calculation of wooden buildings.

Japanese Patent Application Publication No. 2005-316864

In particular, numerical information on strength calculation elements such as earthquake resistance, wind resistance, and load-bearing performance is selective for custom-built houses and freely designed houses, etc., and the owner is asked to determine the structural performance of the wooden building. It is advisable to ask whether the For this purpose, the owner is often asked to fill out a check sheet, but since the check sheet only contains numerical information on strength calculation elements such as seismic performance, wind resistance, and load-bearing performance, the owner does not know what to do. I often wondered whether I should select numerical information based on .
Also, while it is natural for everyone to want numbers that increase strength, it is not immediately clear how this will affect the payment amount, so even if you are asked to check a check sheet, The current situation was that it was not easy to make a decision.

Means 1 is a check sheet for structural calculation of wooden buildings, and the sheet surface has numerical information on each of a plurality of strength calculation elements for obtaining numerical information necessary for structural calculation of wooden buildings. A plurality of check items are displayed in stages according to the size, and each check item is accompanied by an explanation that is reflected in the living conditions according to the size of the numerical information of the strength calculation element. .

As a result of the above, the owner (or person related to the owner) who is the main subject of the check understands the content of the explanation reflected in the living conditions, selects the numerical information of the corresponding strength calculation element, and checks the check item. This eliminates the possibility of being extremely confused about selecting numerical information or mistakenly selecting a check item that is not numerical information that has the effect you expected.
The "check sheet" may be, for example, paper or an electronic panel as long as the checker checks the visualized check area. In other words, the concept includes not only checking an actual sheet (paper) with a writing instrument, but also checking on a touch screen of a computer, which can be called a virtual sheet, such as checking a tablet computer with a smart pen. .
"Multiple strength calculation elements" are elements for acquiring numerical information necessary for structural calculation of wooden buildings, such as seismic performance, wind resistance, load-bearing performance, swaying performance against external forces, and tilting performance against external forces. etc. In these structural calculation formulas, the coefficients for each element are set in stages according to the strength. These can also be further subdivided. For example, load-bearing performance includes snow-bearing performance that is specific to the weight of snow that accumulates on the roof, and floor-bearing performance that is specific to the weight of people and objects in a residence.
"Numerical information on strength calculation elements" is information on, for example, specific values of coefficients in calculation formulas and strength evaluation values corresponding to specific values when performing structural calculations of wooden buildings. The strength evaluation value will be described later. "Specific numerical value" is the numerical value of the coefficient when actually used in the calculation formula for strength calculation. As this value changes, the strength calculation results differ.
``Explanation reflected in living conditions'' is because even if the checker is shown only the numerical information of the strength calculation element, it is difficult to understand what kind of change will occur in the living conditions when that numerical value is selected. , is an explanation for understanding. Therefore, it is better to explain it by replacing it with a familiar phenomenon that is checked. For example, if the strength calculation element is load-bearing performance, it may be set to "a level that is safe enough to hold a piano" or "a level that is safe even if 1 meter of snow accumulates on the roof." For example, if the strength calculation element is seismic performance, it is preferable to replace it with seismic intensity.

Moreover, in means 2, the plurality of strength calculation elements are two or more elements selected from earthquake resistance performance, wind resistance performance, load resistance performance, shaking performance, and tilt performance.
This is because these elements are necessary in the structural calculation of wooden buildings, and they are also elements that require the understanding of the checker.
Further, in means 3, the numerical information is information on the strength evaluation value corresponding to the specific numerical value of the coefficient of the calculation formula used for structural calculation.
If the specific values of the coefficients in the calculation formula are actually written down on a check sheet, it will be difficult for even an expert such as a construction company to understand. Therefore, it is preferable to display the strength evaluation value in other words, "strength evaluation value corresponding to a specific numerical value." For example, if a strength evaluation value of ``grade 1'' is displayed on the check sheet for the standard coefficient value, and the value is a large strength value for the next stage, in actual calculations, a value of 1.25 times is used. Even if it is substituted, when expressing it, a specific numerical value is not displayed as "Grade 2" as the strength evaluation value on the check sheet.
Here, the strength evaluation value is not only a numerical value such as 1.2, but also A. B. It may also be a symbol that can be ordered, such as the alphabet. In this way, by using a rephrased strength evaluation value rather than a specific numerical value, it can be used as an index for judgment of the strength of the building by specialists such as construction companies and designers. However, even if such a paraphrase is used, the owner, who is an amateur, will not be able to understand even the strength evaluation value. Therefore, it is necessary to provide explanations that are reflected in living conditions.

Further, in the means 4, reference numerical information is displayed to be used as a reference when the checking entity checks the selected strength calculation element.
As a result, the standard numerical information that is generally used as a reference for wooden buildings can be displayed in advance on the check sheet, and the checking entity can refer to it and think about where to check, so it is possible for the checking entity to request. Changes to standard numerical information can be made smoothly. For example, if a construction company, which is an expert, determines standard numerical information in advance, it becomes easier for the person checking to make decisions based on that information.
Further, in means 5, the check items corresponding to the reference numerical information are displayed in a different manner from the check items not corresponding to the check items.
As a result, the checker will be able to distinguish between check items that correspond to standard numerical information and check items that do not, based on different display formats. This makes it easier to understand how much change there is.
Examples of "different display modes" include changing the color of the characters and background, or changing the line type of the characters. You may also create a relationship by using the same color for the text and background as the color for displaying reference numerical information, or by using the same line type.

Further, in means 6, the explanation includes information regarding material costs that are changed in accordance with changes in numerical information.
This allows the checking entity to understand how changing numerical information affects material costs, and can use this as a criterion when deciding whether to change numerical values.
"Information regarding material costs" may be, for example, the amount itself, or the rate of increase or decrease for materials relative to a reference value.
Furthermore, in means 7, the explanation is written without using numerical conditions.
This is because if numerical values are used in the explanations themselves, it may be difficult for the checker to make a judgment based on the living conditions unless they understand the meaning of the numerical values. However, if the number is widely known to the population, the meaning of that number will be understood by checkers who have received normal education, so using it will actually make it easier for checkers to understand. In some cases. For example, it is a numerical value such as seismic intensity.

According to the invention of the present application, the checking subject can understand the contents of the explanation reflected in the residence conditions, select the numerical information of the corresponding strength calculation element, and check the check items. You no longer have to worry about selecting information or accidentally select a check item that is not numerical information that has the effect you expected.

Hereinafter, one embodiment of the check sheet of the present invention will be described based on the drawings.
As shown in FIG. 1, the check sheet 1 is configured by being printed on the surface of a prescribed rectangular paper. Information is displayed (written) on the surface of the check sheet 1 in a plurality of (in this case, three) areas. As shown in FIG. 2, information about buildings is displayed in the first area 2. In this embodiment, specific examples of information about the building include the owner's name, building purpose, number of floors, floor height, and total floor area of the building.
As shown in FIG. 3, in the second area 3, performances serving as strength calculation elements and their grades (performance grades) are displayed. In the present embodiment, specific examples of performance grades include earthquake resistance grade, wind resistance grade, snowfall resistance grade, weight grade, and shaking grade. Here, the numerical values of each performance class displayed in the second area 3 are determined based on the building information displayed in the first area 2 by the construction company, based on empirical rules, as the strength of this wooden building. This is a temporary reference value that is subjectively considered to be appropriate, that is, the strength of the building is not too much or too little.

As shown in FIG. 4, a checklist 5 is displayed in the third area 4. Checklist 5 asks the owner to check each of the five factors reflected in intensity calculations, starting from the top: ``Earthquakes,''``Wind,''``Snow,'' ``Weight of people and objects,'' and ``Shaking.'' They constitute first to fifth check column groups 7 to 11.
The first check column group 7 of "About earthquakes" is a check item regarding building strength against earthquake shaking. In the first check column group 7, a check column 12, a grade rank 13, and an explanation 14 are arranged side by side in the horizontal direction, and these are arranged in three columns in the vertical direction in descending order of structural strength of the building. The owner selects one of the three 13 grades (earthquake resistance grade 1 to earthquake resistance grade 3) and checks it in the check box 12 with a writing instrument. At this time, the owner who is the main body of the check reads and understands the explanation content corresponding to each grade rank 13, and checks the check box 12 corresponding to the desired grade rank 13.
Explanation 14 of the basic "Earthquake Resistance Grade 1" states, "This is the minimum standard stipulated by the Building Standards Act. It does not collapse or collapse even under a seismic intensity of 6, and will not be damaged even under an earthquake of 5." Explanation 14 of "Earthquake Resistance Grade 2" states, "It is equivalent to facilities designated as evacuation centers such as schools and hospitals. It is 1.25 times the minimum standard." Furthermore, the building structure has a high strength. Explanation 14 of "Earthquake resistance grade 3" states, "It is equivalent to facilities designated as disaster prevention bases such as police and fire departments. It is 1.5 times the minimum standard." The cells with the standard value of "earthquake resistance grade 3" are colored (in Figure 4, the colored state is indicated by diagonal hatching).

Next, the second check column group 8 of "Regarding wind" is a check item regarding the strength of the building against shaking caused by wind. In the second check column group 8, a check column 15, a grade rank 16, and an explanation 17 are arranged side by side in the horizontal direction, and these are arranged in two columns in the vertical direction in descending order of structural strength of the building. The owner selects one of the two 16 grade ranks (wind resistance grade 1 to wind resistance grade 2) and checks it in the check column 15 with a writing instrument. At this time, the owner who is the main body of the check reads and understands the explanation content corresponding to each grade rank 16, and checks the check column 15 corresponding to the desired grade rank 16.
Explanation 17 of the basic "Wind Resistance Class 1" states, "This is the minimum standard stipulated by the Building Standards Act. It can withstand a typhoon with a wind speed of 50 m/s." Explanation 17 of ``Class 2'' states, ``The structure can withstand winds 1.20 times stronger than the minimum standard.'' The cells with the standard value "Wind Resistance Class 2" are colored (in FIG. 4, the colored state is indicated by diagonal hatching).
Next, the third check box group 9 "About snow" is a check item regarding the load of snow accumulating on the roof. In the third check column group 9, a check column 18, a grade rank 19, and an explanation 20 are arranged side by side in the horizontal direction, and these are arranged in three columns in the vertical direction in descending order of structural strength of the building. The owner selects one of the three grade ranks 19 (snow resistance grade 0 to snow resistance grade 2) and checks the check box 18 with a writing instrument. At this time, the owner who is the main body of the check reads and understands the explanation content corresponding to each grade rank 19, and checks the check box 18 corresponding to the desired grade rank 19.
Explanation 20 of "Snow Resistance Grade 0", which is based on regions with no or little snow, states, "This is a standard specific to regions with little snow. Approximately 0.3 m of snow will not cause damage." Explanation 20 of ``Snow Resistance Grade 1'', which is based on regions where roofs with higher load capacity are required, is ``This is the minimum standard stipulated by the Building Standards Act. Explanation 20 of ``Snow Resistance Class 2'', which means that the building structure is stronger than that, says, ``It is a structure that can withstand snowfall that is 1.20 times the minimum standard.'' The cells with the reference value "snow resistance grade 0" are colored (in FIG. 4, the colored state is indicated by diagonal hatching).

Next, the fourth check box group 10 of "Weight of people and objects" is a check item regarding the load applied to floors supported by bundles, beams, joists, and flooring indoors. In the fourth check column group 10, a check column 21, a class rank 22, a use 23, and an explanation 24 are arranged side by side in the horizontal direction, and these are arranged in four columns in the vertical direction in descending order of structural strength of the building. ing. The owner selects one of the four grade ranks 22 (weight grade 1 to weight grade 4) and checks it in the check column 21 with a writing instrument. At this time, the owner who is the main body of the check reads and understands the explanation content corresponding to each grade rank 22, and checks the check box 21 corresponding to the desired grade rank 22. In the fourth check column group 10, a purpose 23 is also written as an explanation accompanying the explanation 24. Additionally, since there are cases where the weight applied to the floor surface differs depending on the room, there is a special notes field to write down which of weight classes 1 to 4 you would like to apply to each room as special notes. 25 are provided.
Explanation 24 of the basic ``Weight class 1'' is ``This is the weight of a typical residential room.'' Explanation 24 of ``Weight class 2,'' which has a higher strength building structure, is ``The weight of a typical residential room.''"This is when many people constantly come and go on the floor." Explanation 24 of "Weight Class 3", where the building structure has high strength, says, "This is when many people come and go." Explanation 24 for "Weight Class 4", which has high strength, says, "This is when heavy objects such as pianos, bookshelves, and large refrigerators are placed." The cells with the reference value "Weight class 1" are colored (in FIG. 4, the colored state is indicated by diagonal hatching).
Next, the fifth check column group 11 "About shaking" is a check item regarding the degree of temporary deflection of the building due to wind shaking. In the fifth check column group 8, a check column 26, a grade rank 27, and an explanation 28 are arranged side by side in the horizontal direction, and these are arranged in two columns in the vertical direction in descending order of structural strength of the building. The owner selects one of the two grade ranks 27 (sway grade 1 to shake grade 2) and checks it in the check column 26 with a writing instrument. At this time, the owner who is the main body of the check reads and understands the explanation content corresponding to each grade rank 27, and checks the check column 26 corresponding to the desired grade rank 27.
Explanation 28 of the basic "Swaying Class 1" states, "This is our company's minimum standard. It is set assuming that the floor will deflect by a maximum of 8 mm due to external force." Explanation 28 of ``2'' states, ``The setting is based on the assumption that the floor will deflect by a maximum of 5 mm due to external force.This is 1.2 times the minimum standard.'' The squares with the reference value "shaking grade 2" are colored (in FIG. 4, the colored state is indicated by diagonal hatching).

By using such a check sheet 1, the following effects are achieved.
(1) When the construction company takes into account the wishes of the client and decides on coefficients and numerical values to be introduced into the structural calculation formula to ensure that the wooden building has the specified strength, the client may check the coefficients and values without fully understanding them. This eliminates the need to get lost and take time to check.
(2) For example, since grades have ranks, experts can understand them based on their ranks, but amateur owners often do not understand the differences between grades. By adding explanations in this way, it is possible to get a feel for what the grades mean, thereby reducing the discrepancy between what the owner thinks about the strength of the wooden structure.
(3) The numerical value of each performance grade tentatively displayed in the second area 3 can be changed to the current value by coloring the column indicating the grade rank in the first to fifth check column groups 7 to 11 of checklist 5. The construction company will show the strength that it considers appropriate based on its experience and information such as the floor plan and total floor area. Therefore, the owner can make decisions based on this initial information, which shortens the check time.

The embodiments described above are merely described as specific embodiments for illustrating the principles and concepts of the present invention. That is, the present invention is not limited to the above embodiments. The present invention can also be embodied in the following modified aspects, for example.
- The style, grade notation, number of ranks, and explanatory text in check column groups 7 to 11 of Checklist 5 above are examples, and you are free to modify and implement them as appropriate. Additionally, it is also possible to include other factors in the strength calculation, such as the temporary "tilt" of the building when subjected to external forces, to be checked and include an explanation. Conversely, if an element does not require explanation, it is possible to omit the explanation.
・As shown in FIG. 5, in check column groups 7 to 11 for each performance grade of checklist 5 (here, the fourth check column group 10 for "Weight of people and objects" is shown as an example), A "cost" column 29 may be provided to display the rate of increase/decrease in material costs according to the rank of the grade based on the minimum standard. This allows the client to understand that if the strength is increased more than necessary, it will be reflected in the cost, and costs can be reduced. In addition, the rate of increase/decrease in material costs may be displayed based on the reference value of each performance grade displayed in the second area 3 of the check sheet 1.
・In the above, the squares of the grade rank corresponding to the standard numerical value are colored, but since it is only necessary to know that this is the standard numerical value, it is possible to distinguish it by means other than coloring, such as adding a mark or changing the font. It is also possible to make it understandable.
- In the above embodiment, a concrete paper check sheet 1 was taken into consideration, but when requesting a check from a client, a virtual sheet, such as checking a tablet computer with a smart pen, can also be used. good.
