Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rebar processing specification creating apparatus for creating rebar cutting / bending / extending specifications used when constructing a rebar building.

[0002]

2. Description of the Related Art Conventional steel bar processing specifications have been given for one steel bar irrespective of the positional relationship with respect to the skeleton.

[0003]

As a result, the processing specifications of the reinforcing bars in each skeleton component are manually determined one by one while the arrangement data and the reinforcement list data of the skeleton components are held in the computer system in advance. There was the trouble of having to pick up one.

[0004] The present invention has been made in view of the above-mentioned circumstances, and based on the arrangement data and the reinforcing bar list data of skeleton components registered in advance in a computer system, a processing specification of a reinforcing bar used for the skeleton is specified. An object of the present invention is to provide a rebar processing specification creating device that can be automatically derived.

[0005]

According to the present invention, there is provided a rebar processing specification creating apparatus according to the present invention for solving the above-mentioned problems, in which a pre-registered reference point of a reinforcing bar disposed in each structural element is registered. Set with the three-dimensional coordinates based on the layout data and the reinforcing bar list data of the skeleton components, and include the processing specifications of each rebar, the length of the line segment calculated from the three-dimensional coordinates of the adjacent passing reference point, and the rebar. Represented by the relative angle between the base axis selected from the line segment and another line segment or the difference coordinates between adjacent passing reference points, and when represented by the length and relative angle of the line segment, the relative angle Is output as a horizontal angle and a vertical angle with respect to a base plane including the base axis.

[0006] The passage reference point of the rebar refers to, for example, a portion that can serve as an index when indicating the position and shape of the rebar, such as an end point or a bending point of each rebar. The arrangement data is data required to specify the members and locations to be arranged, such as the specifications and arrangement coordinates of the skeleton components and the amount of eccentricity with respect to the grid, and the reinforcing bar list data is the specifications of the skeleton components This is data in which the bar arrangement status set according to is stored. With three-dimensional coordinates based on these, a reference plane (for example, a horizontal plane) on which a skeleton is placed is set as a plane including the X axis and the Y axis,
The coordinates indicated by the three-dimensional coordinate system obtained by adding the Z axis orthogonal to the reference plane are position coordinates calculated from the arrangement status indicated by the arrangement data and the arrangement state indicated by the arrangement list data.

[0007] The processing specification indicates at least numerically a method of processing such as how many times a line segment is followed by bending in any direction. The line segment refers to the straight line portion when the reinforcing bar is linear between the adjacent passing reference points, and when the reinforcing bar is curved between the adjacent passing reference points, both ends of the curved portion. Refers to a virtual straight line connecting. The base surface is a surface selected as the most convenient when expressing the processing specifications. Specifically, it is efficient to use a plane parallel to the two line segments included in each reinforcing bar in that the bending operation can be omitted even a little, but it is selected as constituting the base surface. Workability at the time of machining differs depending on the line segment, and it is often convenient to use the plane containing the longest line segment and the second longest line segment among the line segments included in each reinforcing bar as the base surface. Therefore, it is often convenient to use the longest line segment among the line segments included in each reinforcing bar as a base axis. The difference coordinate between the adjacent passing reference points is a difference between the three-dimensional coordinates between the adjacent passing reference points indicated by an absolute value.In this case, the same reference as the case indicated by the relative angle is used. It is effective to hold and set the base plane of the three-dimensional coordinate system.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a machining specification creating apparatus according to the present invention. The processing specification creating device 7 according to the present invention plays a part of a frame integration related system composed of a so-called personal computer as shown in FIG. 1 and an input / output device connected to the personal computer or the like via various interfaces. Normally, a drawing editing device 8 for inputting a grid, a floor plan, a floor name / height, a frame component list, and a frame specification including each of those specifications, a reinforcing bar used for the frame, concrete It is constructed together with the frame integration device 9 for performing the integration of the above. As is well known, the personal computer or the like is a kind of computer system including a CPU, a memory, and a storage device, and is activated by a program installed in an internal storage device or a program recorded in an external storage device. The processing specification creating means 6 of the processing specification creating device 7 is activated.

Assuming that the frame specification has already been input to the personal computer by the drawing editing device 8, the processing specification creating means 6 is activated.
The dimensions of each skeleton component are determined by the dimension determining means 10. The dimensions are determined as shown in Tables 1 and 2 in terms of the cross-sectional dimensions of continuous foundations, columns and beams, and the thicknesses of continuous foundations, slabs and walls when entering a plan view. The three-dimensional coordinates (reference plane (for example, horizontal plane) on which the frame is placed) automatically set by input operation (numerical input, mouse operation, etc.) for registering drawings and numerical contents of The coordinate is expressed in a three-dimensional coordinate system obtained by adding a plane including the Z-axis perpendicular to the reference plane.

[0010] The dimensions of the continuous foundation, columns and beams in the axial direction are based on the boundary between the skeleton component and the skeleton component existing in the axial direction, or the start point and end point of the skeleton component. The outer edge is set, and the three-dimensional coordinates required to specify the outer edge are calculated, and the three-dimensional coordinates are calculated in consideration of the inclination and curvature of the skeleton component. Furthermore, in the plane dimensions of the slab and the wall, the outer edge is set based on the boundary with the skeleton component existing around the skeleton component or the edge of the skeleton component, and the outer edge is specified. Is calculated in consideration of the inclination and curvature of the skeleton components. In any of the above calculation methods, it is basically performed in a form of calculating a linear distance or a curved distance between points indicated by the three-dimensional coordinates,
Later, by referring to the dimensions obtained in this way and the preset bar arrangement list, the processing specifications of the skeleton components will be derived.

[0011]

[Table 1]

[0012]

[Table 2]

The processing specifications of the independent skeleton components are derived only from the dimensions and the pre-set reinforcing bar list data. In particular, a part of the skeleton such as a column, a beam, a continuous foundation, a slab, etc. In the skeleton component forming the shape, in addition to the determination of the dimensions, by the operation of the continuous information acquisition means 11,
The continuous state of the skeleton components is derived from the layout data included in the plan view, and the processing specifications are derived with reference to the reinforcing bar list data (see FIG. 3). Hereinafter, an example of deriving the continuous state of the vertically continuous columns 12 will be described with reference to FIG. In addition, for convenience, it is represented in a state of being inclined in the drawings.

The continuity information acquiring means 11 refers to the skeleton specification, and as shown in FIG.
Column 12 whose cross section 13 is at least partially overlapped in the direction toward which the reinforcing bar 1 is to be disposed inside the vertically continuous column 12 in accordance with the reinforcing bar list data included in the skeleton component list. They are sequentially connected (see FIG. 2B). In particular, in this example, when arranging the pillar 12,
Are arranged, so that the sections 13 of the columns 12 arranged from the start section 13a to the end section 13b of the continuous column group are sequentially detected.

This processing is performed until all the columns 12 including the reinforcing bar 1 to be connected are detected. When the cross section 13 of the pillar 12 that continues in the direction of the core line P of 12 cannot be detected, that is, when the direction of the core line P of the previous pillar 12 changes in the next column 12, the cross section serving as the starting point of the change , For example, a core line P connecting the three-dimensional coordinates of the center of the cross section between the upper end and the lower end, the upper end and the intermediate point, or the lower end and the intermediate point of the column 12 becomes a new core line P. The connection point of the reinforcing bar 1 arranged in parallel with the column becomes the passage reference point 2 of the reinforcing bar 1 disposed inside the column 12.

Next, the coordinate conversion means 14 is activated, and the three-dimensional coordinates of the passage reference point 2 of each reinforcing bar 1 are calculated by dividing the line segment 3 of the reinforcing bar 1 by two.
The coordinates are converted into relative coordinates with respect to the base plane 5 including one or more. Hereinafter, one rebar 1a is extracted from the column rebar shown in FIG. 2 into a three-dimensional coordinate system as shown in FIG. 4, and an example of a specific conversion procedure is shown.

1) The longest line segment 3 among the line segments 3 connecting the passage reference points 2 (this axis is defined as a base axis 4) 3
Is detected from the reinforcing bar 1a. 2) The entire target rebar 1a formed by connecting a plurality of line segments 3 is moved so that the base axis 4 is parallel to the X axis of the three-dimensional coordinate system, and the coordinates of each passage reference point 2 are set as the target rebar 1b. Update. 3) The second longest line segment 3a among the line segments 3 connecting the passage reference points 2 is detected. 4) The second longest line segment 3a is the XY of the three-dimensional coordinate system.
The entire rebar is rotated about an axis parallel to the X axis so as to be parallel to the plane, and the coordinates of each passage reference point 2 are updated as the target rebar 1c (in this example, the coordinates are updated here. The coordinates are relative coordinates, and the base axis 4, that is, the plane defined by the longest line segment 3 and the second longest line segment 3a is referred to as a base plane 5.)

Subsequently, the angle calculation means 15 uses the relative coordinates converted in this way to calculate each line segment 3 other than the base axis 4.
, The relative angle between the base axis 4 and the other line segment 3 is calculated in the form of a horizontal angle α and a vertical angle β with respect to the base surface 5 including the base axis 4. The calculation result is output to an output device appropriately provided by the activation of the specification output unit 16 by, for example, transferring the entire target reinforcing bar 1c to the XY plane, the XZ plane, or the YZ plane as shown in FIG. A two-dimensional drawing projected on a plane may be displayed, and the horizontal angle α and the vertical angle β and the length of each line segment 3 may be described in each drawing. Note that the above display method does not prevent the relative angle with the line segment 3 other than the base axis 4 as necessary, and in some cases, as shown in the two-dot chain line circle in FIG. In some cases, the distance may be represented by the length of a line segment 3 defined by the adjacent passage reference points 2 and 2 and the difference coordinates between the adjacent passage reference points 2 and 2.

In the example of FIG. 7, a line segment 3 of 550 mm is taken from one end of the reinforcing bar along the Z-axis, and 56 m from the end of the passage reference point 2 in the Y-axis direction (the back side of the paper, the same applies hereinafter).
m, 674 mm in the Z-axis direction (upward on the paper, the same applies hereinafter),
It is bent in the X-axis direction (rightward on the paper, the same applies hereinafter) in a direction indicating a point separated by 3370 mm, a line segment 3 having a length of 3440 mm is taken, and further, a passage reference point 2 which is an end of the line segment 3
Is bent in a direction pointing to a point at a distance of 57 mm in the Y-axis direction, 689 mm in the Z-axis direction, and 2870 mm in the X-axis direction. It is displayed that processing such as taking three minutes is performed. That is, in this example, the base line 17 by the X axis and the Z axis is constituted by the line segment 3 of 550 mm and the line segment 3 of 695 mm corresponding to the start end and the end of the reinforcing bar.

The processing specification creation processing as described above can also be applied to the processing including a curved column shown in FIGS. 5 and 6, and in this case, the processing specification of each rebar is also changed to the adjacent passage reference point 2. , 2
Is determined by the length of the line segment 3 determined by the following formula and the relative angle between the base axis 4 selected from the line segment 3 included in the reinforcing bar 1 and another line segment 3 or the difference coordinates between the adjacent passage reference points 2 and 2. 18
Can be sufficiently clearly shown including the amount of bending.

[0021]

As described above, if the processing specification creating apparatus according to the present invention is used, not only the processing specifications of the reinforcing bars included in a single skeleton component, but also the continuous configuration over a plurality of skeleton components. The processing specifications of the reinforcing bars included in the system can be quickly created using the arrangement data of the building components and the list of reinforcing bars input to the computer system in advance. The complexity of manually picking up the processing specifications one by one can be eliminated.
