Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building process management system, and more particularly to a building process management system that automatically generates a process management table necessary for house building process management.
[0002]
[Prior art]
In the construction of houses, a process control table is prepared in advance, and a series of various work from the start to the completion is carried out according to this process control table. This process management table is indispensable for management of construction cost estimation, material arrangement, management, worker arrangement, construction progress, etc. Producing a process management table properly shortens the construction period. And directly reduce the construction cost.
[0003]
Conventionally, a process management method has been studied as a production management technique in the manufacturing industry widely including the construction industry. A typical example is a CPM process management method (critical process method).
[0004]
In addition, development of computer systems that rationally perform work planning and process management in building construction and the like is underway. As this type of prior art, Japanese Patent Application Laid-Open No. 9-21231 and Japanese Patent Application Laid-Open No. 11-193431. Various things such as a gazette have been proposed, and further, process management software that can be used on a personal computer is actually used.
[0005]
[Problems to be solved by the invention]
Unlike small buildings, such as single-family houses, schedules are created by assigning work items to standard schedules prepared in advance, while referring to construction drawings and accumulated materials. The work is picked up, and the standard process chart is modified and created manually or by a personal computer.
[0006]
For example, when selecting a process schedule for a typical model house as a standard process schedule and creating a process schedule for an individual house, compare the floor area and floor plan of that house with that of the model house, and use the same work items. Is applied to the standard process chart and the time is adjusted according to the floor area and the floor plan. In this case, the basic standard for creating the process chart is the floor area.
[0007]
For this reason, work that takes several days for the same work, for example, the sash installation process, etc., is roughly classified as a sash installation process on the first floor and a sash installation process on the second floor. Since specific differences in the layout of individual houses and ease of work are discarded and are not reflected in the process chart, a deviation appears between the actual work volume and the work volume on the process chart. In addition, there is a problem that the goal of work to be completed in one day is not clear.
[0008]
Therefore, an object of the present invention is to solve the problems of the prior art, accurately reflect the conditions of each house such as a floor plan in the process chart, and the actual work amount required for the work in one day. An object of the present invention is to provide a building process management system capable of automatically generating a process chart capable of clearly grasping a work target to be finished.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a building process management system for managing a series of work processes of construction work of a building, in which CAD drawing data and material data of the building are accumulated. A storage means for storing a work time calculation master file in which data of unit work in which a work amount and work time are associated with each other as a data base for work time calculation is stored as a database , A work group consisting of independent unit processes as constituent elements, and a work group consisting of unit processes that consolidate unit works that share materials or floors across multiple rooms into room units. more of a step master file to set the working group, CAD drawing data and location to be used of materials and material from the material data of the building of the construction schedule, Reads the amount, picked up work items and work of the unit work, against said working time calculation master file, and means picking unit operation counts the operation time for each unit process, the data of the step master file In addition, each unit process is grouped by work group, and a totaling means for totaling work time by work group, and assigning each work group in accordance with a predetermined standard process table, in particular, materials across multiple rooms. Or, for a work group belonging to a work group whose unit element is a unit process in which unit works common to floors are aggregated into room units, each unit process is arranged in the order of adjacent rooms and assigned to the process chart to generate a process chart. And means.

These master files will be further described later.
[0013]
FIG. 2 is a process diagram showing all processes related to the construction of a detached house. There are various processes in the construction of a residential building. The types of work performed by carpenters in connection with the construction of the building itself include the basement, the upper building, and the woodwork (manufacturing) in the order of construction. Other construction related to the building includes temporary work, foundation work, roof work, exterior wall work, cloth work, tile work, tatami work, etc., but these work is performed by specialized craftsmen. Other specialized craftsman works include electrical work, gas work, water supply / drainage work, and ant work.
[0014]
In the case of ordinary residential buildings, the construction progresses from construction to foundation work and foundation work. In carpentry work, only the upper wing works together by multiple carpenters. Are often in charge of construction until the final process. Moreover, since woodwork has a wide range of work types and takes a long time, it is more important to create an appropriate work schedule than other works.
[0015]
Therefore, the process generation for the woodwork with the longest process days will be described as an embodiment of the present invention and will be described in detail below.
[0016]
FIG. 3 is a diagram showing a work group constituting a series of steps of the woodwork. In this work group, some unit processes defined by a predetermined standard are gathered to form one work group. For example, the work group SG1 of the first process is a plurality of unit processes that constitute the foundation of the building, marking, foundation ventilation member installation, distribution between foundations, drilling anchor bolts, foundation installation, anchor bolt tightening, large pulling It consists of unit processes such as mounting and under floor storage. These unit processes are processes that do not have such a property that each of the unit processes is independently common.
[0017]
On the other hand, for example, if the work group SG6 is a work group for attaching window lintels, such work is commonly performed on the first and second floors of the building, and the same floor is used. However, it is a work that spans rooms such as a Japanese-style room, a Western-style room, and a living room. Unit processes constituting such a work group are room-unit processes. The work of attaching the sash is also a work group composed of unit processes in units of rooms. Such work groups are registered in advance in the process master file 25 as data as shown in FIG. The unit process to which each work group belongs is identified by a process code. For all work groups not shown in FIG. 4, the unit processes are registered in the same manner and assigned process codes.
[0018]
Next, FIG. 5 is a diagram showing data registered in the work time calculation master file 24 in which data serving as a basis for work time aggregation is stored.
[0019]
As shown in FIG. 5, the classification is for distinguishing whether the construction is foundation work or the like, and construction on the first floor or construction on the second floor. The process code corresponds to the unit process code shown in FIG. In the unit work item, all unit work items necessary for process generation are registered.For example, when installing a window sill or sash, all specifications of the window sill are registered. Each unit time required for the mounting operation is preset in minutes. These unit work data are registered for all work.
[0020]
Here, FIG. 6 shows an example of a CAD drawing of a target building for process generation. When the arithmetic processing unit 22 d reads the CAD data and the corresponding material data from the CAD database 16, the arithmetic processing unit 22 d picks up all unit operations shown in the CAD drawing.
[0021]
For example, FIG. 6 is a plan view of the first floor. For example, the floor area and wall area of each room such as a living room, a Japanese-style room, a kitchen, a bathroom, and a toilet are calculated and necessary for the construction of the floor of each room. Pick up unit work by picking up materials and materials necessary for walls. In addition, the necessary unit work is picked up by picking up all materials and fittings such as the window sill, magsa, number of studs, number of sashes and specifications of each room. Such unit work is picked up on all CAD drawings of the building such as the second floor plan, the front view of the building, and the base plan view.
[0022]
Next, the arithmetic processing unit 22d picks up the unit work by matching the picked-up material with the data of the work time calculation master file 24 shown in FIG. FIG. 7 shows an example of unit work picked up from CAD data on the first floor. In this case, the unit work picked up is totaled for each process code, so that the work time can be totaled as a unit process.
[0023]
In this way, all unit operations are tabulated by process code, so that unit operations are grouped for each unit process. Then, the arithmetic processing unit 22d aggregates all unit processes by work group while referring to the process master file 25 of FIG. For example, in the sash-attached work group SG12, as shown in FIG. 8, the unit processes of sash attachment for each room are grouped into the work group SG12, and the work time is totaled for each unit process.
[0024]
Next, each tabulated work group is assigned to a standard process chart registered in the process master file 25 to generate a process chart. FIG. 9 shows a part of the generated process chart. When generating the process table, the tool / material master file 26 is referred to, and necessary materials and necessary tools are picked up, aggregated for each work group, and assigned to the process table. Within the work group, the unit processes for each room are preferably arranged in the order of adjacent rooms based on CAD data. Also, the operating rate for one day is calculated. Here, the operating rate refers to the ratio of the total working time of the unit process calculated by the work group to the management time, where the working time per day is 8 hours as a reference management time.
[0025]
In this way, by introducing the concept of a work group and summarizing unit processes, the target value of the daily work can be clarified. In addition, since work with common materials and the like is generated as a process in units of rooms, the conditions of individual houses such as floor plans can be accurately reflected in the process chart.
[0026]
As described above, the present invention has been described by taking the process generation of the woodwork as an example. However, the process management system of the present invention incorporates a function of writing a work record in the generated process and a function of updating the generated process. May be. Further, the process generation is not limited to the wood work but can be applied to other works.
[0027]
【The invention's effect】
As is apparent from the above description, according to the present invention, a work group having independent unit processes as constituent elements, and a unit work that shares materials or floors across a plurality of rooms are made room units. By setting up multiple work groups consisting of work units that have aggregated unit processes as components, and uniting the unit processes for each work group, the conditions of individual housing such as floor plans are accurately reflected in the process table. In addition, it is possible to automatically generate a process chart that can clearly grasp the actual work amount necessary for work and the work target to be completed in one day.
