Description

  The present invention relates to a construction plan system and a construction plan program for creating a construction plan for a building.

In the construction plan when constructing a building from the past, the choice of which construction method to use is limited to the scope of the construction planner's experience, so there are very few construction method options for one project. Limited. As a result, there is a possibility of selecting a plan different from the optimal solution when the plan is tried for many construction methods. On the other hand, if a construction plan is made for a large number of construction methods and compared with each other, there is a problem that the time and labor required for the plan increase.
In addition, as a prior art, there is known a frame construction method planning system capable of comparing a plan simulation reflecting various condition settings and a plan plan in a short time by modeling design information and construction information. (For example, refer to Patent Document 1).

  By the way, many systems that can make construction plans for building construction methods have been developed, but all of them create building data and construction method data that assume the construction method, and aggregate the data group. Quantity, cost or unique evaluation value is calculated. When the construction method to be applied is changed, it is necessary to correct / re-input the building data or the construction method data. Further, the conventional construction planning system is essentially in charge of only a simple counting function, and it takes a lot of man-hours to input data for delivery to the system. For this reason, conventional construction planning systems often have the main purpose of confirming the workability of a single construction method or a very small number of variations after the construction plan is fixed to some extent. There is a problem that has been reduced.

  This invention is made | formed in view of such a situation, and it aims at providing the construction plan system and construction plan program which can compare and examine the construction plan of many construction methods in a short time.

It has been created a process chart information by placing working length, by aggregating the construction quantities steps, and characterized in that a construction plan information output means for generating and outputting a construction planning information To do.

  The present invention further includes a building shape data defining means for defining the shape data of the building.

  According to the present invention, since the building shape data and the construction method data are separated, once the building shape data is created, the construction plan can be drafted in combination with other construction method data, so that the data correction Thus, there is an effect that it is possible to compare and examine the construction plans of a number of construction methods in a short time without re-input. Further, by eliminating the construction method information from the building shape data, the building shape data can be extremely simplified, and as a result, the input time can be greatly reduced. In addition, it is possible to carry out construction plan simulation at the initial stage of design (stage where construction method is undecided) and to feed back construction knowledge to the design at an early stage. It is possible to select a construction method with a small amount of work, and rework and recalculation can be reduced.

  Hereinafter, a construction planning system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment. In this figure, the code | symbol 1 is the construction plan part which outputs the construction plan information of a building. Reference numeral 2 is a conditional statement database in which conditional statements for defining members constituting the building are stored in advance. The code | symbol 3 is the process sentence database in which the process sentence for defining the member which comprises a building is stored beforehand. Reference numeral 4 denotes a construction method data generation that inputs a conditional statement stored in the conditional statement database 2 and a processed statement stored in the processed statement database 3, and generates and outputs construction method data for each construction method. Part. Reference numeral 5 denotes a construction method database that stores construction method data output by the construction method data generation unit 4 for each construction method. Here, it is assumed that the construction method data 51 of the steel lamination method, the construction method data 52 of the full PC method, and the construction method data 53 of the RCSS method are stored. Reference numeral 6 denotes a building shape database in which shape data of a target building for which a construction plan is drawn is stored. Reference numeral 7 denotes a building shape defining unit configured by a three-dimensional CAD system or the like. Reference numeral 8 denotes a member type estimation database that stores data to be referred to when a member type is estimated based on building shape data read from the building shape database 6. The aspect ratio and the member type of the members constituting the building Data associated with the information is stored. Reference numerals 9, 10, and 11 are construction plan information output by the construction planning unit 1. The construction plan information includes construction schedule information 9, construction information 10 necessary for construction and resources, and construction quantity information 11 for each floor and each work area.

  Next, the processing operation of the construction planning system shown in FIG. 1 will be described. In order to solve the problems of the prior art, the construction planning system according to the present invention outputs a construction plan for a large number of construction methods with a very small amount of labor and time in the construction plan, so that a comparative study can be performed. It is. In order to construct this system, the building shape data and the construction method data are separated, and the same building shape data can be used even if the construction method to be examined is changed. It is possible to output a construction plan with a completely different construction method such as construction. The building shape data depends on the request of the client and includes a unique building shape, and the construction method data is data relating to a method of building that exists independently of the shape data of the target building.

The building shape data obtained by designing by the building shape defining unit 7 needs to be designed to satisfy the following conditions and stored in the building shape database 6.
(Condition 1) An area occupied in the space of “members (columns, beams, floors, walls, etc.)” constituting the building is defined.
(Condition 2) Connection between members is defined (it is not necessary to be physically connected).
(Condition 3) Since the space area indicating the member needs to be divided during the planning process, the same expression is applied before and after the dividing process.

  Further, each “member” constituting the building shape data stored in the building shape database 6 does not include data depending on the construction method such as member cross section, material, joint position, unitization, and the like. Building shape data is greatly simplified by eliminating all building-related attributes other than location and rough range (geometric data). The geometric data representing the member does not indicate a cross section of the member but indicates a space that envelops the member. When individual construction method data is applied in the construction planning process described later, attributes such as an H-shaped cross section, a square cross section, and a circular cross section are given. Since the connection between members can be determined from the area occupied by the space of the members, it is not always necessary as data to be created. The connection information does not need to be physically connected (= the space area indicated by the “member” data is consistent), and the connection information is set when it is determined that the person is connected with common sense. Accordingly, when the girder is arranged between the two columns, the girder is allowed to be connected to the two columns even if the end of the girder is not in contact with the surface of the column. As the simplest example, a “member” is defined in a rectangular parallelepiped region arranged in space. An example of building shape data is shown in FIG.

On the other hand, the construction method data stored in the construction method database 5 is data in which construction part definition, construction order, work step, necessary resources (temporary, machine, labor, place, etc.), cost, and the like are defined. Construction method data includes the following data.
(1) Description of construction method, features and conditions of use.
(2) Definition of construction parts (definition of joint position, provision of construction quantity such as welding amount and number of bolts).
(3) Definition of the method of determining the work area (for example, creating a work area for every fixed area or creating a work area so that the construction quantity is constant).
(4) Process definition (required work, work context, target construction parts, required resources (machinery, temporary work, labor, etc.), input amount, work step).
An example of construction method data of the steel lamination method is shown in FIG.

  In this construction method data, one data group is defined for one construction method such as “steel laminated construction method”, and a large number of construction method data for construction methods that can be constructed are prepared in advance. Since this construction method data does not depend on the building shape data, it can be defined in advance. The construction method data is described in a computer-readable rule base format so that it can be processed by a computer program. For this description, “If a construction part belongs to a 'pillar' and faces the internal opening, we estimate three column stages.” “A certain construction part belongs to the 'floor' and is placed on the outer periphery. If the front side is not PCCW, a vocabulary necessary for construction planning is prepared. That is, the description necessary for the construction plan “facing the internal opening” and “arranged on the outer periphery” is possible.

  Here, with reference to FIG. 3 to FIG. 5, an operation in which the construction method data generation unit 4 shown in FIG. 1 generates construction method data with reference to the conditional statement database 2 and the processed statement database 3 will be described. FIG. 3 is a diagram illustrating an example of a conditional sentence stored in the conditional sentence database 2. FIG. 4 is a diagram illustrating an example of the processed text stored in the processed text database 3. These are fixed databases that do not depend on construction methods. “◯” in the figure indicates a parameter, and a numerical value or a character string is substituted when the construction method data is generated. The construction method data generation unit 4 generates construction method data for each construction method with reference to the conditional statements and processing statements shown in FIGS. 2 and 3, and stores them in the construction method database 5. The construction method data shown in FIG. 5 is an example of the construction method data of the steel lamination method. Similarly, construction method data such as “full PC construction method” and “RCSS construction method (a construction method in which a column is a reinforced concrete structure and a beam is a steel frame structure)” are generated, and each construction method data is stored in the construction method database 5. The construction method data is stored.

  Next, with reference to FIG. 2, the operation | movement in which the construction planning part 1 outputs construction plan information is demonstrated. At the time of planning the construction of the target building, first, building shape data is created by the building shape defining unit 7 and stored in the building shape database 6, and the desired construction method data is selected, and the building shape data and construction method data are selected. One construction plan is created for each combination.

  The construction planning unit 1 reads the building shape data from the building shape database 6 (step S1), and estimates the member type such as a column, a large beam, a small beam, a floor, and a wall (step S2). In the member type estimation database 8, the correspondence data of the aspect ratio and the member type is stored in advance for estimating the member type, and the construction planning unit 1 refers to the data stored in the member type estimation database 8. Then, the member type of the read shape data is estimated. For example, a case where the width and depth are the same and the height is 3.5 times or more the width (or depth) is estimated as a “pillar”.

  Next, the construction planning unit 1 normalizes the estimated member (step S3). Normalization here is a process of aligning the unit of members when applying construction method data. For example, in the case of a pillar, one member is arranged so that there is no break or overlap from FL to FL. That is. This normalization process is closely related to the construction method data design, but generally, the range divided by the floor and the span is set to 1 “member”.

  Next, the construction planning unit 1 divides the building shape data for each normalized member (step S4). And the construction plan part 1 provides an attribute with respect to each of the divided | segmented member (step S5). This attribute assigning process is a process of reassembling “members” into construction parts in accordance with construction method data. For this, it is only necessary to specify the division position. In the case of a pillar, the construction method data specifies that a joint is provided at a location of FL + 1m, or that a large beam is provided with a bracket type joint at a position 1.2m from the column core. Since it is defined, the parts are divided according to this and assembled according to the connection information, so that a final construction part is created. As for the outer wall, it is described that one span is divided into panels of 2.4 m, or an invisible panel from FL-1.0 m to FL + 1.0 m is made, so that it corresponds to the target construction method. Construction parts will be generated.

  Next, the construction planning unit 1 assigns attributes such as a welding length and a concrete placement amount to each construction part. This is also performed as specified in the construction method data. If the structure is steel, the welding length and the number of bolts are given. If the structure is RC, the formwork area and the concrete volume are given. Moreover, what is not given as a member shape, such as a rebuilding jig or a column stage in a steel structure, is given here as an attribute. Subsequently, the construction planning unit 1 is allocated to the work sections according to the positions of these construction parts, and totals the number of construction parts in each floor, each work section, the construction quantity such as the welding length, and temporary materials such as the rebuilding jig (step S6). . Thereby, the construction quantity of each floor and each work area was calculated.

  Next, the construction plan 1 calculates the time of each work (such as column construction) by multiplying / dividing the step and labor / machine inputs described in the construction method data stored in the construction method database 5. To do. Since the context of the work is given by the construction method data, the process table information is created by arranging the work having a length calculated based on the construction method data. In addition, the construction planning unit 1 outputs construction plan information by, for example, calculating the cost by summing up the construction quantity of one cycle process, multiplying labor, and multiplying the unit price (step S7). This construction plan information is output by printer output or screen display. As a result, the construction process schedule information 9, the pile information 10 of resources and labor necessary for construction, and the construction quantity information 11 for each floor and each work section are output. FIG. 8 shows an example in which construction process schedule information 9 is displayed on the screen. FIG. 9 shows an example of a screen display of resource / labor load information 10 necessary for construction. FIG. 10 shows an example in which construction quantity information 11 for each floor and each work section is displayed on the screen.

  By separating building shape data and construction method data in this way, once building shape data is created, construction plans can be drafted in combination with other construction method data. Without input, it is possible to compare and review construction plans for many construction methods in a short time. Further, by eliminating the construction method information from the building shape data, the building shape data can be greatly simplified, and as a result, the input time can be greatly reduced. In addition, it is possible to carry out a construction plan simulation at the initial stage of design (stage where the construction method is not yet determined), and construction knowledge can be fed back to the design at an early stage. In addition, when the basic design is completed, it is possible to select a construction method with less risk, thereby reducing rework and recalculation.

  1 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by the computer system and executed, thereby executing the construction plan creation process. May be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
