[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a building work efficiency system suitable for use in general work related to building, such as building design, multiplication, construction, maintenance, and renovation.
[0002]
[Prior art]
In recent years, CAD (Computer Aided Design) systems have been used in various fields such as architecture, circuit diagrams, aircraft, and cars. For example, in a general architectural CAD system, shape data and attribute information of an object corresponding to each structural element of a building are defined in advance, and those data are called up at the time of design, and are displayed on a display screen. By arranging each object in the drawing area, a design model of the building is created, thereby saving the labor of the design work.
[0003]
As a system in which this kind of CAD system is combined with other related systems and databases, for example, a building database CAD system disclosed in JP-A-2001-243267 is known.
This building database CAD system is configured by combining a building-based 3D-CAD, a unique database, and related systems such as an estimation system, an ordering system, and a construction drawing creating system, and connecting these with an mutual interface. In this construction database CAD system, the quantity of each component is calculated based on the quantity information of the object corresponding to each component of the building and the attribute information of the object, and this is shared in the system. This is useful for tasks such as estimation and order management.
[0004]
[Problems to be solved by the invention]
However, in the above-mentioned conventional construction database CAD system, only a small part of the information required for the construction-related work is shared in the system, and this alone increases the efficiency of the whole construction-related work. Was insufficient to achieve In other words, the act of building is an accumulation of the act of joining (or possibly disassembling) a plurality of components, and various resources such as technology, cost, time, and work environment for the act, or the act. Environmental impact, waste, by-products, etc. In general, as information to be managed in construction-related work, there is much more information about joining and separation between components than information about components themselves. For example, if another component called an aluminum sash is attached to the opening of a component called a reinforced concrete wall, trying to calculate the construction cost of this part, the cost for building this wall, the sash In addition to the cost of the sash, the cost of the sash work to attach the sash to the wall must be added to the cost, and in addition to this, the process of the formwork installing the sash anchor on the formwork in advance, Various construction processes, such as the process of filling mortar into the gap between the sash and the seal for waterproofing, are concentrated on the joint between the wall and the sash, and it is necessary to add up all the related costs. In addition, these construction steps vary depending on the difference in the attributes of the objects to be joined, for example, if the wall is a dry construction wall, it will be different. Therefore, simply sharing the quantity information of the constituent elements is not enough to improve the efficiency of the whole work related to the construction, and it has been difficult to obtain a significant work improvement effect.
[0005]
The present invention has been made in view of such circumstances, and it is possible to share not only the quantity information of the building components but also information relating to the process of joining or disassembling the building components in the system. For example, in the construction cost estimation business, it is possible to build a system that automates the process from picking up the calculation items to the calculation of the number of items based on the CAD data created by the design department and the creation of an estimate, etc. An object of the present invention is to provide a building work efficiency improvement system capable of dramatically improving efficiency.

Further, the CPU 11 determines the joint state of the objects based on the shape data and the position information of each object, and based on the result of the determination, determines the joint information of the objects (the classification of the building components corresponding to the objects having the joint relationship). A code, a joint form data, and a joint amount) are created and stored in the storage area of the storage device 15.
[0013]
The CPU 11 constitutes a quantity information output unit according to the present invention, and counts the number of each building component based on the number of objects created by the CAD system 20 and the attribute information of each object. A process for storing the counting result in the form quantity database 23 in the storage device 15 is executed.

Here, in order to make the contents of the processing easy to understand, the description will be given by taking an example in which only a specific phase of the building project is targeted.
[0020]
First, in step S1, a process of creating a design model of a building is performed using the basic functions of the CAD system 20. In this process, based on the instruction input from the input device 14, an object corresponding to each component of the building is created, and the attribute information of the object (identification information or classification code of the corresponding building component, classification code, building configuration). In the storage area of the storage device 15, information such as quantitative information on elements, and information on joints between objects (a classification code of building components corresponding to each object in a joint relationship, joint form data, joint amount), and the like are stored. Execute the process.
[0021]
Next, in step S2, the quantity of each building component is counted based on the attribute information and the quantity of each object stored in the storage area of the storage device 15 in step S1, and the counting result is stored in the form quantity database 23.

[0022]
Next, in step S4, a process of acquiring building process information corresponding to the joining relationship information stored in the form quantity database 23 from the building process information database 21 and storing the acquired building process information in a predetermined storage area of the storage device 15 is performed. .
Next, in step S5, the building component is calculated based on the relationship between the coefficient or the arithmetic expression included in the building process information acquired in step S4 and the joint amount included in the joint information between the objects stored in the form quantity database 23. A process of calculating quantity data of items relating to joining / separation therebetween and storing the calculated data in a predetermined storage area of the storage device 15 is executed. As a result, the storage area of the storage device 15 stores the quantity information of each building component and the quantity data of the item related to joining / separation between the building components, whereby the information is stored in the building work efficiency improvement system. It becomes a shared state within 10. Thereafter, the shared information is output to a related system such as an integrating system or an ordering system in accordance with various instructions input from the input device 14.

In addition to outputting the counting result, a combination of building components in a joining relationship is extracted based on the relationship between the objects, and building process information corresponding to the joining relationship information of the combination is acquired from the building process information database 21. Since the information is output in the form, not only the quantity information of the building components but also the building process information relating to joining and separating the building components can be shared in the system.

[0025]
In the present embodiment, in the process of creating a design model of a building, a classification code corresponding to each building component is acquired from the building member classification code table 22 and added to the attribute information of the object. However, the present invention is not limited to this. For example, immediately before acquiring the building process information from the building process information database 21, the classification code corresponding to each building component is acquired from the building member classification code table 22. May be stored in the form quantity database 23. Further, in the present embodiment, the configuration is such that the classification code is automatically given in the CAD system 20. However, for example, a configuration in which the user sets and inputs the classification code when creating the design model is also possible. Similarly, in this embodiment, the CAD system 20 is configured to automatically derive the quantitative information (area, perimeter, etc.) of the building components. However, for example, when the user creates the building It is also possible to adopt a configuration in which the quantitative information is set and input.
[0026]
Further, in the present embodiment, the joining state between the objects is determined in the CAD system 20, and the relationship between the constituent elements is automatically detected based on the judgment. For example, the user has the joining relationship. By selecting a combination of objects or by setting and inputting as attribute information by the user, the relationship between the constituent elements may be detected in the system.
[0027]
In addition, as a method of extracting joint state information from CAD data, in addition to a method of directly outputting joint relation information by a CAD system application program, a form and position information of each object is output once by a CAD system application program, There is also a method of analyzing the output information by an application program other than the CAD system, grasping the joint relation information, and outputting the information.
Further, in the present embodiment, the case where the building work efficiency improvement system 10 is configured by a single computer system has been described as an example, but the present invention is not limited to this. It is also possible to configure the efficiency improvement system 10. Further, in this case, each process of the CPU 11 described in the present embodiment may be executed in a distributed manner by the CPU of each computer system.
[0028]
The method of creating an object model based on the input to the CAD system 20 includes a method in which the input person directly inputs the three-dimensional shape of the architectural component, and a method in which the input two-dimensional shape and the input two-dimensional shape are separately provided. A method of indirectly generating a three-dimensional object by processing height information such as a ceiling height of a room obtained by an application program of the CAD system 20 is also included.
[0029]
【The invention's effect】
As explained above, according to the building work efficiency system according to the present invention, not only the quantity information of the building components, but also the resources and by-products necessary for the building / renovation / demolition process after interpreting the configuration state Information is grasped and managed, it becomes possible to systematize the application of complex practical knowledge to a building model on CAD.
