  In the structural calculation of the conventional formwork support as described in Patent Document 1, a designer or the like needs to input the load conditions (body size, concrete type, construction load, etc.) by himself / herself. In addition, since it is necessary for a designer or the like to set the specifications (material used, arrangement interval) of the formwork support work, there is a problem that the processing becomes complicated and takes time. Furthermore, since the calculation system only performs pass / fail judgments based on the above set conditions, when making a reasonable plan, the materials and intervals of the formwork support work must be changed in various ways, and each changed condition must be calculated. There was a problem of having to.

  According to the present invention, a reasonable form support work plan in the target area can be obtained, and the time required for creating the form support work plan can be shortened. Furthermore, the formwork support costs such as material costs and labor costs can be automatically calculated, and the most economical formwork support can be selected.

  In the formwork support calculation of the present invention, information such as the shape and dimensions of building components is processed with digital values. Examples of such digital processing will be described with reference to FIGS. FIG. 18 is an explanatory diagram illustrating an example of building information stored in the building information storage unit A of the storage unit 14 illustrated in FIG. FIG. 18A shows a folder structure set in a tree shape. Under the “building” folder, the “floor”, “beam”, and “column” folders are set. Below the “Floor”, “Beam”, and “Column” folders are “Object Basic Data”, “Position Data”, “Shape Data”, “Material Data”, “Joint Data”, “Process Data”. Each folder is set. FIG. 18 shows an example of internal data of the building information model.

  18B is stored in each folder of “object basic data”, “position data”, “shape data”, “material data”, “joining data”, and “process data” in FIG. 18A. It is explanatory drawing which shows the example of data. In these data, specific characteristics are set in the (s) column corresponding to each item in the (r) column. In this example, as object basic data, a structure name is set as a floor slab, an object ID is set as ID, and a structure type is set as conventional RC. As position data, the member coordinate system is set by a three-dimensional vector of X, Y, and Z.

As material data of member 1, the material type is ordinary concrete, design standard strength Fc
(N / mm ² ) and unit volume weight ρ (N / mm ³ ) are input. As the position data, center positions X01, Y01, Z01 (mm) of the member 1 are set. As the shape data of the member 1, the dimension 1 is set as a three-dimensional vector of Xe, Ye, and Ze. As the process data, the material age (day) of the work day of the member 1 is set.

  For the member 2, material data and position data are set in the same manner as the member 1. As the shape data of the member 2, dimensions 1 to 12 are input. For example, in the dimension 1 column, the diameter of the upper stripe and the pitch of the upper stripe are input. With regard to the “fixing method” of the joining data, for example, in the fixing 1, it is set whether or not the joining is performed in a state where the upper end of one end is placed on the upper part of the upper end of the other end.

  FIG. 19 is an explanatory diagram illustrating an example of building information described in digital information. In this example, a floor slab divided into 35 sections S1 to S35 as shown in FIG. 20 is targeted. FIG. 20 is a diagram for calculating the strength of a building member when a heavy machine enters the floor. “Floor slab” is set in the structure name in the column (c) of FIG. An appropriate ID is set for the object ID in the column (d). “Conventional RC” is set in the structure format of the (e) column. In (f) to (n), the member coordinates X1 to X3, Y1 to Y3, and Z1 to Z3 are set as digital values. 0 and 1 in the columns (f) to (n) are examples.

  For example, when the member 1 shown in FIG. 18 is concrete and the member 2 is a reinforcing bar, the center coordinates (X1, Y1, Z1) of the member 1 are (1, 1, 1), and the center of the member 2 The coordinates (X2, Y2, Z2) are (1, 1, 0). When the member 3 is not used, the center coordinates (X3, Y3, Z3) are (0, 0, 0).

  In FIG. 19, only the position data which is a part of the building information is shown as a digital value. However, the material data, shape data, process data, etc. as described in FIG. The column is described with a digital value. Here, digital values are used as an example of the format of electronic data. However, the digital values are not particularly limited as shown in this table as long as the computer can recognize the data and exchange data during program execution. That is, in the embodiment of the present invention, all building information is described as digital values. Since the present invention is intended for formwork support work, as the building information of FIG. 18 (a), as will be described later, the “support plate”, “jita”, “outline”, which are members of the formwork support work, “Stand” etc. are described.

  FIG. 1 is a flowchart showing a calculation processing procedure of formwork support in an embodiment of the present invention. In FIG. 1, a calculation target part (zone) determination process program is started in S1. Here, the calculation target part (area) corresponds to a specific floor of a building to be processed, a specific area of the floor, and the like. Next, the load condition is calculated in S2. At this time, information such as the slab thickness, the slab size, and the concrete type is acquired from the building information model. In addition, information on the loading load such as a load load and an impact load is acquired from the construction plan model. In S3, a member for using a formwork (siding plate, joist, large draw, support) is selected. In this process, one combination of materials to be used for each part (skin plate, joist, large draw, support) is selected.

In S4, the formwork support interval is calculated. This process is based on the information on the load condition obtained in the process of S2 and the information on the structure of the formwork use member obtained in the process of S3.
The arrangement interval of each member is calculated from structural safety and rationality. Details of this processing will be described later. In S5, the formwork support cost is calculated (material cost, labor cost). In this process, the number of members is calculated, and the labor progress is obtained from the database. In S6, the presence or absence of comparison with other conditions is determined. If the determination result is N, the result of S5 is regarded as the optimum result without comparing with other conditions, that is, the most economical case of formwork support. Determination is made and the process proceeds to S7. If there is a combination of formwork support that has not been examined other than the combination of formwork support set in S3, the loop processing from S3 onward is repeated again. By repeating this process, select the formwork support members (feathers, joists, large draws, struts), calculate the formwork support interval by combining each formwork use member, and each combination The formwork support cost can be calculated. Finally, for all the combinations, when the examination up to S5 is completed, the process proceeds to S6, and the one with the lowest formwork support cost is selected and the process proceeds to S7. The output process of S7 outputs drawings of building information as shown in FIGS. If the determination result is Y, the process returns to S3, and the loop process after S3 is repeated. By following the above procedure, a case that minimizes the cost of the formwork support can be automatically calculated. In the above description, the case of minimizing the cost of formwork support has been described. However, by changing the content to be calculated in S5, the number of formwork support members and the total number of formwork support members It is possible to automatically calculate a combination of formwork support that optimizes other selection conditions such as weight and construction period.

FIG. 2 is a flowchart showing an example of calculating the formwork support interval, and FIG. 3 is an explanatory diagram of the processing of FIG. The flowchart showing the calculation of the formwork support interval in FIG. 2 shows a specific example of “calculation of formwork support interval” which is the process of S4 in FIG. In FIG. 11A, which will be described later, an example of the arrangement of the “shelves 1”, “Jota 2”, “Ohiki 3”, and “post 4” which are structural members of the formwork support is described. . In FIG. 2, the calculation condition determination process is started in S11. This process determines the design load W (n / m ² ), the formwork support material, and the allowable deflection of the formwork support. In S12, the maximum support interval of the plate 1 is calculated. This calculation can be easily calculated from the knowledge of structural mechanics. However, as shown in FIG. 3A, the design load W (n / m) is applied to the board 1 supported by the joist 2. ² ), the maximum support interval T of the plate 1 by the joist 2 is calculated so that the allowable stress (bending moment, shear) of the plate 1 and the allowable deflection of the plate 1 are satisfied. It is.

The joist 2 is examined in S13. In this process, as shown in FIG. 3B, it is assumed that the design load W (n / m ² ) is applied to the joist 2 supported by the large pull 3, and the allowable stress degree (bending of the joist 2) The condition (condition A) of the joist interval and the joist span Ya satisfying the moment (shear) and the allowable deflection of the joist 2 is obtained. This calculation can also be easily calculated from the knowledge of structural mechanics. The joist span Ya corresponds to the interval between the large pulls 3-3. Subsequently, the joist span and joist interval satisfying the condition A within the maximum support interval T of the dam 1 by the joist 2 are obtained. This condition is shown as a range on the left side of the straight line Da and below the curve Db in FIG. The joist span Ya does not exceed the width of the floor of the building. Therefore, assuming that the number of lines in the drawing is Na and the effective width of the floor of the building is Wf, the relationship Ya = Wf / (Na-1) is established. The effective width of the floor of the building is the distance that has escaped inward from the distance between the centers of the pillars to the extent that it does not interfere with the installation work such as drawing. Therefore, when Na = 2, the joist span Ya is determined from the width of the floor, and the maximum joist interval in this case is obtained as the intersection of the straight line Da or the curve Db in FIG. Actually, because there is a pillar, it is not possible to install a large fork to the full floor width of the building, and the effective width Wf of the floor is set slightly smaller than the width of the floor of the building. When a combination of the number of large draw columns, joist span, and joist interval is found in this way, the number of large draw columns is incremented by one and the same calculation is repeated. As the number of lines is increased, the combination of the joist span and joist interval is obtained as the intersection of Da, that is, the joist interval is the maximum support interval T of the board 1 by the joist 2, but in that case, The calculation for increasing the number of large draw columns Na is not performed.

In S14, Daiki 3 is examined. In this process, as shown in FIG. 3C, assuming that the design load W (n / m ² ) is applied to the large pull 3 supported by the support column 4, the allowable stress degree of the large pull 3 is obtained. A large drawing interval (joe span) and a large drawing span condition (condition B) that satisfy (bending moment, shear) and satisfy the allowable deflection of the large drawing 3 are obtained. This calculation can also be easily calculated from knowledge of structural mechanics. In FIG. 13B, it is shown as the lower range of the curve Ha. The large drawing interval (joe span) is determined from the floor width and the number of large drawing rows Na as before, so the maximum value of the large drawing span is calculated in order from Na = 2. Here, the calculation beyond the Na that was terminated in S13 is not performed. Finally, it is confirmed whether or not the axial force applied to the column is less than the allowable axial force when the pulling span (V) is the maximum value. If the axial force applied to the support is less than the allowable axial force, in S15, the result of examination on the type of the dam, joist, large draw, and the type and interval of the support is output. FIG. 3 (d) shows an output example of the examination result of S15, and the type and size of the material of each part of the formwork support (strip board, joist, large drawing, support) are described in a table format. ing.

In FIG. 4, the construction plan model (A) sets (1) “self-weight”, (2) “loading load”, and (3) “impact load” as the load for calculation of formwork support. (1) In “self weight”, weight data is acquired from a building model and a construction object ID is set (a). For the approximate formwork load, 40 kg / m ² is used as the initial value, and it is settled after the formwork specification is determined (b). (2) In “loading load”, a construction method such as pumping, the number of workers such as earthwork, and a work machine installed such as a generator are set.
