Description

  The present invention relates to an apparatus for determining whether or not bar arrangement at a joint between a beam and a column in a reinforced concrete building is properly performed.

At the joint between beams and columns in a reinforced concrete structure (RC structure), many rebars are complicated, but even in such a state, it is possible to arrange the gaps between the rebars appropriately. is important.
In designing the structure, first, the cross-sectional area of the reinforcing bar, the reinforcing bar strength, the beam width, and the column width are determined by the structural design.
Then, the design for the rebar fitting, that is, the detailed arrangement of the reinforcing bar, is performed by manual dimensional calculation or drawing, and if it does not fit, the structural calculation is performed again.
However, enormous time was required for dimension calculation and drawing.
Therefore, a bar arrangement design support method has been proposed as a solution to such problems (see Patent Document 1).

  The reinforcing bar design support method proposed in Patent Document 1 is described as follows: “A bar arrangement pattern input process for inputting a bar arrangement pattern of a joint between a beam and a column to a computer, and a basic method for inputting basic data including a cover thickness to the computer. Based on the data input process, the dimension data input process for inputting dimension data including the size of beams, columns, beam bars, and column bars to the computer, and the bar arrangement pattern, basic data, and dimension data input by the above process A bar arrangement design support method including a bar arrangement drawing creation step of creating a bar arrangement diagram by a computer, wherein the bar arrangement pattern input step is performed on a grid pattern screen prepared in advance. It is characterized by selecting a muscle position "(refer to claim 1 of Patent Document 1).

Japanese Patent Publication No. 7-76975

As mentioned above, the detail design of how to arrange bars and columns is based on the beam width and column width determined by the structural calculation, with a certain margin, and the beam width and column. The width is set, and the setting is performed based on the set beam width and column width.
Since it is very complicated to perform such detailed arrangement of the bar manually, as shown in Patent Document 1, a bar arrangement design support method has been proposed.

  However, the bar arrangement design support method disclosed in Patent Document 1 is merely a method that can automate what is conventionally performed manually. That is, the beam width and the column width are set with a predetermined margin in the beam width and the column width obtained by the structural design, and the bar arrangement detailed design is performed based on the set beam width and the column width. In the detailed arrangement of the bar arrangement, whether or not the bar arrangement is possible is determined by actually drawing a drawing, and a specific mode of the bar arrangement is designed.

However, the method for determining whether or not bar arrangement is possible by drawing a drawing is an extension of the prior art, and is a complicated operation in the first place.
Moreover, even if the beam width and column width are obtained in the structural design, there is a problem of interference between the bar arrangements of the orthogonal beams at the part where the two beams are orthogonal to the corner column. It is unclear how much room should be taken for the beam width and column width obtained in the above, and the current situation is that they are determined at the discretion of the skilled worker.
Furthermore, regardless of the case where the bar arrangement is the outermost edge, the so-called two-stage or three-stage reinforcement that is arranged inward of the outermost edge is more complicated. It is the actual situation that is done by.

  Therefore, an object of the present invention is to provide a technique capable of supporting so that the bar arrangement can be performed as easily as possible even in the case of a complicated bar arrangement in which two beams are orthogonal to a corner column. It is said.

As described above, the bar arrangement design support method disclosed in Patent Document 1 is to automate the drawing of the bar arrangement that has been performed manually and is merely an automated task.
In other words, the conventional idea is to set the beam width and column width by empirically leaving the beam width and column width obtained by the structural calculation, and detailing the reinforcement arrangement based on the set beam width and column width. Is to do. Accordingly, the beam width and the column width, which are the basis for the detailed bar arrangement design, are set based on experience, so to speak, so that the detailed bar arrangement design cannot be performed properly in the first place.
In particular, in beam-column joints where orthogonal beams are joined to the corner columns, the bar arrangement is complicated, and it is not possible to predict at all when two-stage bars or three-stage bars are arranged. It is.

Therefore, the inventor, regarding the current detailed bar arrangement design, the beam width and the column width set with a margin with respect to the beam width and column width obtained by the structural design should arrange a predetermined reinforcing bar. I thought about judging in advance whether or not is possible. In other words, as a pre-stage of detailed bar arrangement design using drawings, we thought that it would be very easy to handle the situation if it was determined whether or not bar arrangement was possible.
Since such an effect is large in the part where the bar arrangement is the most complicated, it was examined in the joint between the corner column and the orthogonal beam where the bar arrangement is the most complicated.

As a first step, the inventor examines whether the column width obtained by the structural calculation and the beam width are equal to or larger than the minimum width required when the bar is actually arranged. We decided to determine whether reinforcement can be arranged on the obtained beam and column cross section.
Therefore, first, the case of the first-stage bar arrangement was examined as a basic form.
Note that the single-level bar arrangement is a case where all the reinforcing bars are arranged at the outermost edge in the case of a beam, for example. In addition, the two-stage bar arrangement means a case where a reinforcing bar is arranged at the outermost edge and a reinforcing bar is arranged inside thereof.

The inventor is a column beam joint where the orthogonal beam is joined to the target beam connected to the corner column. The minimum column width was calculated and a database with the table as a table was created.
Then, it was considered to obtain the minimum beam width and the minimum column width in the case of two-stage bar arrangement and three-stage bar arrangement using this one-stage bar arrangement database.
The beam width and column width calculated from the structure calculation and set by the designer with empirical margins are calculated based on the calculated column width and beam width stored in the database that is originally required. Whether or not the set value is appropriate is determined depending on whether or not it is above.

  The present invention has been made based on such knowledge, and specifically comprises the following constitution.

[Embodiment 1]
An embodiment of the present invention will be described with reference to the drawings. The present embodiment is a case where the number of beam main bars of two orthogonal beams (the target beam and the orthogonal beam) is equal.
The bar arrangement appropriateness determination device 1 according to the present embodiment is a bar arrangement appropriateness determination device that determines whether or not the bar arrangement of a column beam whose beam is orthogonal to a corner column is appropriate. Storage means 3 for storing a database in which the column and beam sizes are recorded, information input means 5 for inputting information on planned dimensions such as column sizes, reading means 7 for reading out necessary information from the database, and reading out Based on the information and the information input by the information input means 5, a determination means 9 for determining the suitability of the planned dimensions and a display means 11 for displaying the determination result are provided.
Note that the database, the reading unit 7, the determination unit 9, and the like are realized by the CPU executing a predetermined program.
Hereinafter, each configuration will be described in more detail.

<Storage means [database]>
The memory | storage means 3 is comprised by memory | storage devices, such as memory, and has memorize | stored the information memorize | stored in the database so that reading is possible.
The database shows the concrete cover thickness, main reinforcement information (main steel grade, diameter, number of column outermost edges, number of beam main reinforcement steps and number), reinforcement reinforcement (reinforcing bar, band reinforcement) information for the case of one-stage reinforcement. The required column size and beam size are recorded based on the diameter of the reinforcing bar.
The contents of the database will be described in detail below.

As a premise for explaining the details of the database, the form of bar arrangement targeted by the database, specifically, the bar arrangement form of a column beam in which two beams are orthogonal to a corner column will be described with reference to FIG.
FIG. 2 shows a state in which the beam is orthogonal to the corner column 13, FIG. 2 (a) is a plan view, and FIG. 2 (b) is a cross-sectional view taken along the line AA in FIG. FIG.2 (c) is sectional drawing which follows the arrow BB line of Fig.2 (a). 2B and 2C, the main bars of the column are omitted from the viewpoint of preventing the drawings from becoming complicated.
For convenience of explanation, the beam in the Y direction is referred to as the target beam 15 and the beam in the X direction is referred to as the orthogonal beam 17 because the beam is orthogonal to the target beam 15 in the Y direction.
In the example of FIG. 2, four column main bars 19 are arranged on the outermost edge of the column. Further, the target beam 15 has a single-stage reinforcement, and the target beam main reinforcement 21 has three upper bars and three lower bars. The orthogonal beam 17 is also a one-stage reinforcement, and the orthogonal beam main reinforcement 23 has three upper bars and three lower bars.
In addition, in FIG. 2, the arrangement | positioning of the reinforcing bar at the time of becoming a two-stage reinforcement is shown with the broken line.

In the bar arrangement shown in FIG. 2, the required size of the beam to be arranged without interfering with the reinforcing bar is shown in the table shown in FIG. 3, and this table shown in FIG. 3 is one of the databases. is there.
The required size of the beam for reinforcing bars to be arranged without interfering is the bending inner diameter (D) of the reinforcing bar, the main beam diameter and the number of reinforcement bars and the number of beam main bars, and the main bar diameter of the orthogonal beam 17. This is set for each and is stored as a database in a table as shown in FIG.
For example, in the case of bending inner diameter (D): 4d (d is a numerical value of the main bar name), main bar diameter: D29, barb diameter: D13, target beam main bar number: 3, orthogonal beam main bar: D25 In the table shown in FIG. 3, it is 353 mm as shown by being surrounded by a broken-line circle.

  The table shown in FIG. 3 is a summary of the dimensions of the inventor that should be secured by the inventor for each of the conditions shown in the table.

Next, the required size of a pillar is demonstrated based on FIG. 4, FIG.
As shown in FIG. 4, the minimum column width (required column width) is set based on the target beam main bar diameter, the number of target beam main bars, the orthogonal beam main bar, the column main bar diameter, and the band bar diameter, This is compiled as a table in FIG. 4 and stored as a database.
For example, in the case of the target beam main bar diameter: D19, the number of target beam main bars: 2, orthogonal beam main bar: D29, the column main bar diameter: D19, and the band bar diameter: D13, encircle them with a broken line in the table shown in FIG. As shown in FIG.
The table shown in FIG. 4 is similar to the table in FIG. 3 and is compiled by examining each dimension of the conditions shown in the table to determine if the inventor should secure the interference of the reinforcing bars. It is.

  Note that the beam size in FIG. 3 and the column size in FIG. 4 have a relationship that the column size can be obtained by adding a predetermined cover thickness to the beam size, so that if one can be specified, the other can be specified.

<Information input means>
The information input means 5 is means for inputting information related to planned dimensions such as column size. Specifically, it includes a keyboard and a memory that temporarily stores information input through the keyboard.
The information input by the information input means 5 includes column / beam plan dimensions including column plan size, beam plan size, concrete cover thickness, and main bars including steel type, diameter, number of column outermost edges, number of beam main bars and number. Information and reinforcement information about the diameter of the reinforcement.

<Reading means>
The reading means 7 reads necessary information from the database.
As described above, the database is a collection of column sizes and beam sizes that are required to prevent interference of reinforcing bars in the first-stage reinforcement. However, there are cases where the number of steps increases from the outermost edge toward the inside of the beam, for example, two-step bar arrangement and three-step bar arrangement. In the case of such a multi-level bar arrangement, rebars are complicated and interference problems are likely to occur.
However, when there are a plurality of stages, it is extremely complicated and cumbersome to construct a database as shown in FIGS. 3 and 4 for each stage.
Therefore, the inventor considered that the database for the one-stage bar arrangement shown in FIGS. 3 and 4 is applied to a plurality of stages, and realized it by devising the reading means 7 for reading information from the database. .
In the following, the method will be described.

The example shown in FIG. 2 is a case where the target beam 15 and the orthogonal beam 17 are arranged in one stage as described above, and the reinforcing bars of the first stage reinforcement are indicated by solid lines.
In the case of one-stage bar arrangement, see the intersecting frame of the one-stage shape of “Specification method of dimension in X direction” and the one-stage shape of “Specific direction of dimension in Y direction” in the table shown in FIG. 0/0], which means that the addition of the number of main bars of the target beam 15 in the table shown in FIG. 4 is 0, that is, the number of main bars in one stage in the table of FIG. It means that it can be applied as it is.
Therefore, in this case, when reading information from the table of FIG. 4, the reading means 7 reads the column size information in the column of the number based on the number of main streaks in one stage.
If the column size can be specified from the table of FIG. 4, the beam size can also be specified by subtracting a predetermined cover thickness.

As shown in FIG. 7, both the target beam 15 and the orthogonal beam 17 have two-stage reinforcement, and the second stage of the target beam 15 and the orthogonal beam 17 is not full reinforcement but full reinforcement (3 The case where the number of reinforcements is one less than that of the book (two) will be described.
In this case, as shown in FIG. 8, “(upper) one-stage full, two-stage streaks (one or more less)” and “specific direction of Y-direction dimension” in the two-stage form of “X-direction dimension identification method” In the two-stage shape, [0/0] is seen in the intersecting frame of “(bottom) one-stage full, two-stage streaks (one or more less)”, and this meaning is the object in the table shown in FIG. This means that the addition of the number of main bars of the beam 15 is 0, that is, it means that the number of main bars in one stage in the table of FIG. 4 can be applied as it is.
Therefore, also in this case, when reading information from the table of FIG. 4, the reading means 7 reads the column size information in the column of the number based on the number of main streaks in one stage.

  As shown in FIG. 9, when the target beam 15 and the orthogonal beam 17 are both arranged in two steps, the second step of the target beam 15 is one less than the full reinforcement (two). There will be described a case where the second stage of the orthogonal beam 17 is full reinforcement (three bars). In addition, in the arrow view of FIG. 9, the side view of the reinforcing bar of the beam that is full reinforcement shows the beam in color. For example, in FIG. 9B, the orthogonal beam 17 is colored. This point is the same in the following drawings.

In the case as shown in FIG. 9, as shown in FIG. 10, “(upper), 1 and 2 full steps” and “specific direction of Y direction” are two stages of “specification method of X direction dimension”. If you look at the intersecting frame of “(bottom) one-step full, two-step streaks (one or more less)”, it is [0 / + 1]. Since the “X direction dimension specifying method” side is “0”, this means that the addition of the number of main bars in the table shown in FIG. This means that the number of main streaks in the first stage in the table of 4 can be applied as it is.
Therefore, when obtaining the column size to which the target beam 15 is joined, the reading means 7 reads information on the column size in the column of the number of columns based on the number of main bars in one stage when reading the information from the table of FIG. Is read.

On the other hand, since the “Y direction dimension identification method” side is “+1”, this means that for the orthogonal beam 17, the addition of the number of main bars in the table shown in FIG. 4 is “1”. That is, it means that the table can be applied by adding “1” to the number of main streaks in one stage in the table of FIG. For example, when the number of the first stage of the orthogonal beam 17 is 3, the table in FIG. 4 can be applied as it is by looking at the four frames.
Therefore, when obtaining the column size to which the orthogonal beam 17 is joined, the reading means 7 reads out information from the table of FIG. 4 based on the number of main bars obtained by adding 1 to the number of main bars in one stage. Read column size information.

As shown in FIG. 11, when the target beam 15 and the orthogonal beam 17 are both arranged in two stages, the second stage of the target beam 15 is full reinforcement (three), and the two stages of the orthogonal beam 17 are arranged. The case where the eye has one bar arrangement (two bars) less than the full bar arrangement will be described.
In this case, as shown in FIG. 12, “(upper) 1-stage full, 2-stage streaks (one or more less)” and “specific direction of Y-direction dimension” in the two-stage form of “X direction dimension specification method” If you look at the intersecting frame of “(bottom), 1st, 2nd full)”, it is [+1/0]. Since the “X direction dimension specification method” side is “+1”, this means that the addition of the number of main bars in the table shown in FIG. 4 is “1” for the target beam 15. That is, it means that the table can be applied by adding “1” to the number of main streaks in one stage in the table of FIG. For example, when the number of the first stage of the orthogonal beam 17 is 3, the table in FIG. 4 can be applied as it is by looking at the four frames.
Therefore, when obtaining the column size to which the target beam 15 is joined, the reading means 7 reads the information from the table of FIG. 4 based on the number of main bars which is obtained by adding 1 to the number of main bars in one stage. Read column size information.

On the other hand, since the “Y direction dimension identification method” side is “0”, this means that for the orthogonal beam 17, the number of main bars in the first stage in the table shown in FIG. 4 can be applied as it is.
Therefore, when obtaining the column size to which the orthogonal beam 17 is joined, the reading unit 7 reads the column size information in the column of the number based on the number of main bars in one stage when reading the information from the table of FIG. Is read.

As shown in FIG. 13, when the target beam 15 and the orthogonal beam 17 are both arranged in two stages, the second stage of the target beam 15 is full reinforcement (three), and the two stages of the orthogonal beam 17 are arranged. The case where the eyes are also fully arranged (three) will be described.
In this case, as shown in FIG. 14, “(upper), 1 and 2 full steps” in the two-stage “specifying method in the X direction” and “(( Looking at the intersecting frame of “Bottom 1st, 2nd Full”, it is [+ 1 / + 1]. Since the “X direction dimension specification method” side is “+1”, this means that the addition of the number of main bars in the table shown in FIG. 4 is “1” for the target beam 15. That is, it means that the table can be applied by adding “1” to the number of main streaks in one stage in the table of FIG. For example, when the number of first beams of the target beam 15 is two, the table in FIG. 4 can be applied as it is by looking at the three frames.
On the other hand, since the “Y direction dimension specifying method” side is also “+1”, this means that “1” is added to the number of main bars in the first stage in the table shown in FIG. This means that the table can be applied.
Therefore, in this case, when the column size to which the orthogonal beam 17 is joined and the column size to which the target beam 15 is joined is obtained, the reading unit 7 reads the information from the table of FIG. Based on the number of main bars obtained by adding 1 to the number of main bars, information on the column size in the column of the number of bars is read.

As described above, in the case of the two-stage bar arrangement, the necessary column size can be read out using the table of FIG. 4 in which the column sizes necessary for the first-stage bar arrangement do not cause interference of the reinforcing bars. it can.
When the required column size is known, the required beam size can be obtained from a predetermined relationship.

When the meaning of the table of FIG. 6 is generalized, when the number of steps m of the target beam and the number of steps n of the orthogonal beam are the same, that is, when m = n,
The column size (X dimension) to which the target beam is attached is the number of the main beam of one stage of the input target beam + (m-1) when the maximum number of steps for arranging the full number of target beams is m. ] Read the column size for the number of beam main bars from the database,
Column size for the number of beam main bars of [input target beam + 1 stage beam main bar number + (m-2)] when the maximum number of steps of full bar arrangement of the target beam is m-1 Are read from the database.
The column size (Y dimension) to which the orthogonal beam is attached is the number of the main beam of one step of the input orthogonal beam + (m-1) when the maximum number of steps of arranging the full number of orthogonal beams is m. ] Read the column size for the number of beam main bars from the database,
When the maximum number of reinforcing bars for the full number of orthogonal beams is m-1, the column size for the number of main bars of the input beam + (m-2)] Are read from the database.
When m = 1, the column size for the number of beam main bars in one stage of the input beam is read from the database.

The fact that this generalization is correct will be verified with reference to FIG. 6 in the case of a three-stage bar arrangement in which the number of steps of the bar arrangement is three for both the target beam and the orthogonal beam.
As specific reinforcement, the following cases are assumed.
Target beam: 1 step = full reinforcement (4), 2 steps = full reinforcement (4), 3 steps = 1 less than full reinforcement (3)
Orthogonal beam: Full reinforcement (4 bars) for both 1st, 2nd and 3rd stages
In this case, according to the above generalization, the (minimum) column size (X dimension) of the columns to which the target beams are joined has a maximum number of steps for arranging the full number of the target beams to be two. This corresponds to the case where the maximum number of reinforcing bars for the full number of target beams is m−1. In this case, [the number of input main beam of the target beam + (m−2)], that is, 4 + 1 = You will see the column of the number of five reinforcing bars.
The (minimum) size (Y dimension) of the column to which the orthogonal beam is joined is 3 (maximum number of orthogonal beams). This corresponds to the case where the maximum number of stages of bar arrangement is m. In this case, [the number of beam main reinforcing bars in one stage of the input orthogonal beam + (m−1)], that is, the number of reinforcing bars of 4 + 2 = 6 You will see the column.

When the above specific example is verified based on the table of FIG. 6, “(upper) 1, 2, 3 full” and “Y” are obtained from the table of FIG. Looking at the intersecting frame of “(bottom), 1st, 2nd full, 3rd streak (1 or more less)” in the three-stage shape of “specific direction of direction dimension”, it is [+ 1 / + 2]. Since the “X direction dimension specifying method” side is “+1”, the addition of the number of main bars in the table shown in FIG. In addition, since the “Y direction dimension identification method” side is “+2”, since the addition of the number of main bars in the table shown in FIG. It will be.
Thus, the result is the same as the above generalization, and it can be seen that the above generalization is correct.

<Determination means>
The determining means 9 determines the suitability of the planned dimensions based on the information read by the reading means 7 and the information input by the information input means 5. For example, if the column size input by the information input unit 5 is larger than the column size read by the reading unit 7, it is determined that the column size is appropriate (OK). Conversely, the column size input by the information input unit 5 is determined by the reading unit 7. If it is smaller than the read column size, it is determined as non-conforming (NG).

<Display means>
The display means 11 is constituted by a monitor, for example, and displays the determination result. Further, it is preferable that the input information input by the information input means 5 can be displayed.

A method for determining whether or not the planned column / beam size is appropriate by the bar arrangement appropriateness determination apparatus 1 configured as described above will be described.
By means of the information input means 5, column / beam plan dimensions including column plan size, beam plan size, concrete cover thickness, main bar information including steel type, diameter, number of column outermost edges, number of steps and number of beam main bars, and reinforcing bars When reinforcing bar information relating to the diameter of the bar is input, the input information is displayed on the display means 11.

When the input of information is completed, the operator clicks a determination execution button displayed on the screen, for example, and reading of information by the reading unit 7 and a determination operation by the determining unit 9 are started.
As described above, the reading unit 7 reads the column / beam size necessary for the reinforcing bar not to interfere from the database based on the input information.
When the column / beam size required by the reading unit 7 is read, the determining unit 9 determines the suitability of the planned dimensions based on the information read by the reading unit 7 and the information input by the information input unit 5. The determination result is displayed on the display means 11.

  As described above, according to the present embodiment, the database constructed for the first-stage reinforcement can be used even in the case of a multi-stage arrangement of two-stage arrangements and three-stage arrangements. It can be simplified. In this way, by using a simplified database, it is possible to automatically determine whether or not the planned dimensions have been manually performed by a computer.

[Embodiment 2]
The reading means 7 in the first embodiment is for the case where the target beam and the orthogonal beam have the same number of steps. In the second embodiment, the function of the reading unit 7 when the number of stages of the target beam and the orthogonal beam is different will be described. The configuration other than the reading means 7 is the same as that of the first embodiment.

As shown in FIG. 15, when the target beam 15 has a three-level bar arrangement and the orthogonal beam 17 has a two-level bar arrangement, the target beam 15 has a full bar arrangement (three) in all three levels and is orthogonal. An example will be described in which the second stage of the beam is not full reinforcement but one arrangement less than full arrangement (three).
In this case, in the table shown in FIG. 6, “(upper) one-step full, two-step streaks (one or more less)” and “specific direction of Y-direction dimension” in the two-step form of “X-direction dimension specification method” If you look at the intersecting frame of “(bottom) 1,2,3 full”, it is [+1/0].

Since the “X direction dimension specification method” side is “+1”, this means that the addition of the number of main bars in the table shown in FIG. 4 is “1” for the target beam 15. That is, it means that the table can be applied by adding “1” to the number of main streaks in one stage in the table of FIG. In this example, since the number of first beams of the target beam 15 is 3, the table of FIG. 4 can be applied as it is by looking at the four frames.
On the other hand, since the “Y direction dimension specifying method” side is “0”, this means that the orthogonal main beam 17 can be applied to the number of main bars in the first stage in the table shown in FIG. .
Therefore, when obtaining the column size to which the target beam 15 is joined, the reading means 7 reads the information from the table of FIG. 4 and the number of four main bars obtained by adding +1 to 3 which is the number of main bars in one stage. The column size information in the column of the number is read based on.
When obtaining the column size to which the orthogonal beam 17 is joined, the reading means 7 reads the information from the table of FIG. 4 based on the number of the three main bars which is the number of main bars in one stage. Read the column size information in the column.

Thus, even when the number of stages of the target beam 15 and the orthogonal beam 17 is different, the table of FIG. 6 can be used, and this point generalizes the meaning of the table of FIG. 6 as in the first embodiment. In the case where the number of steps m of the target beam is different from the number of steps n of the orthogonal beam, that is, m ≠ n, the number of beam main bars of the two orthogonal beams is m steps (target beam) and n steps (orthogonal beam) ( m> n)
The column size (X dimension) to which the m-stage beam (target beam) is attached is the number of beam main bars of the input target beam + (n-1)] Read the column size from the database,
The column size (Y dimension) to which the n-stage beam (orthogonal beam) is attached is set to [the beam main bar of the input orthogonal beam when the maximum number of stages for arranging the full number of orthogonal beams is n. The column size for the number of beam main bars of (number + (n-1)) is read from the database, and when the maximum number of bars for arranging the full number of orthogonal beams is (n-1), [input The column size for the number of beam main bars of the orthogonal beam + (n−2)] is read from the database.

The fact that this generalization is correct will be verified based on FIG. 6 in the case where the number of reinforcing bars is 4 (m = 4) and the number of orthogonal beams is 3 (n = 3).
As specific reinforcement, the following cases are assumed.
Target beam: Full reinforcement (4 bars) for both 1st, 2nd, 3rd and 4th levels
Orthogonal beam: 1 stage = full reinforcement (4), 2 stages = full reinforcement (4), 3 stages = 1 less than full reinforcement (3)
In this case, according to the above generalization, the (minimum) column size (X dimension) of the columns to which the target beams are joined is [the number of main beam bars of one stage of the input target beam + (n−1)]. That is, the column of 4 + 2 = 6 rebars is seen.
The (minimum) size (Y dimension) of the (minimum) column of the columns to which the orthogonal beams are joined is (n−1) because the maximum number of stages for arranging the full number of orthogonal beams is two. In this case, the column of [number of main bars of the input orthogonal beam + (n−2)], that is, 4 + 1 = 5 rebars is seen.

When the above specific example is verified based on the table in FIG. 6, it is found from the table in FIG. 6 that “(upper), 1st, 2nd full, 3rd streaks (1 or more less) ) ”And“ (Specification of Y direction dimension) ”, and the frame intersecting“ (bottom) 1, 2, 3, 4 steps full) ”is [+ 2 / + 1]. . Since the “X direction dimension specifying method” side is “+2”, the addition of the number of main bars in the table shown in FIG. Also, since the “Y direction dimension specifying method” side is “+1”, the addition of the number of main bars in the table shown in FIG. It will be.
Thus, the result is the same as the above generalization, and it can be seen that the above generalization is correct.

In addition, when the number of steps of the orthogonal beam is 1 (n = 1), the column size (X dimension) to which the target beam is attached is the number of beam main bars of [number of input beam main bars per stage]. The column size for the number of main bars of the orthogonal beam is read from the database.
This is because when n = 1, n-2 takes a negative value, and when n-2 takes a negative value, it is treated as 0.

  As described above, even when the number of steps of the target beam and the orthogonal beam is different, the database constructed for the first-stage reinforcement is a plurality of two-stage reinforcements and three-stage reinforcements as in the case of the first embodiment. Since it can also be used in the case of step reinforcement, the database can be greatly simplified. In this way, by using a simplified database, it is possible to automatically determine whether or not the planned dimensions have been manually performed by a computer.

[Embodiment 3]
In the first embodiment, the case where the number of steps of the target beam and the orthogonal beam is equal is described, and in the second embodiment, the case where the number of steps of the target beam and the orthogonal beam is different is described.
That is, when only the case where the number of steps of the target beam and the orthogonal beam is assumed to be the same as the form of reinforcement, the first embodiment is sufficient, and the number of steps of the target beam and the orthogonal beam is different as the form of reinforcement. Embodiment 2 is sufficient when only this is assumed.
However, when both the case where the number of steps of the target beam and the orthogonal beam is equal and the case where the number of steps of the target beam and the orthogonal beam are different are assumed, the reading means 7 has both functions of the first and second embodiments. It only has to be.
When the reading means 7 has both functions of the first and second embodiments, both the case where the number of stages of the target beam and the orthogonal beam are equal and the case where the number of stages of the target beam and the orthogonal beam are different are assumed. However, as in the case of the first and second embodiments, the database constructed for the first-stage reinforcement can also be used in the case of a multi-stage arrangement such as a two-stage arrangement and a three-stage arrangement. Can be greatly simplified. In this way, by using a simplified database, it is possible to automatically determine whether or not the planned dimensions have been manually performed by a computer.

  The table shown in FIGS. 3 and 4 referred to in the above description is an example when the reinforcing bar is a U-shaped bar as shown in FIG. 2, but for example, when the reinforcing bar is a vertically separated type, FIG. Although the required beam size and column size shown in FIG. 4 change, it is determined whether or not the bar arrangement is appropriate for the multi-level bar arrangement by creating a table for the single-level bar arrangement as in FIGS. 3 and 4. This is the same as the point that is possible.

  The arrangement appropriateness determining apparatus 1 of the first to third embodiments as described above can be constructed by a single personal computer (PC). However, as shown in FIG. 16, the database, the reading means 7, and the determining means 9 are connected to the Internet.
