Abstract

PURPOSE:To make it possible to embody the standardization of manhour based on a statistical ground and perform sophisticated manhour estimation promptly and accurately by inputting a process factor for the execution of building construction and calculating a process required time and displaying their output. CONSTITUTION:Building conditions, site conditions, administration conditions and execution conditions, which are process factors of building construction, are input into an input unit 1. Then, an arithmetic operation unit 2 computes a real manhour by digitalizing the input process factors statistically and multiplying a standard manhour to the computed value, thereby converting the real manhour into a process required time. The process required time is output- displayed in an output unit 3. With regards to the output display, the process required time is represented by the length of a segment which extends on a time-scaled axis where a starting point of the segment stands for the start of construction work while an end point of the segment stands for the end of construction work.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man-hour accumulating device for accumulating and displaying the actual man-hours required for constructing a house or the like.

[0002]

2. Description of the Related Art Conventionally, in order to arrange workers, estimate construction costs, and calculate profits necessary for building construction,
Construction scale, building specifications, site conditions such as temperature and precipitation, man-hours of incidental work, construction range, regional disparities such as building material prices and personnel costs, worker proficiency, operating time, and construction difficulty I had to make a comprehensive judgment on the factors, and relied on the experience and intuition of a skilled engineer.

[0003]

However, with the diversification of consumers' tastes, recent building types are becoming more diverse and complicated, and therefore, the integration method relying on the experience and intuition of a skilled person is difficult. Sometimes there was a big difference with reality. For this reason, the reliability of the estimation is low, and particularly when a subcontractor or the like is requested to carry out the construction, the problem that the construction period, cost, etc. are difficult to predict is remarkable. In addition, auxiliary work is also complicated, and it is difficult to accurately grasp and judge all the process factors mentioned above.

An object of the present invention is to provide a man-hour accumulating device which can standardize man-hours based on a statistical basis so that complicated man-hour accumulating can be performed quickly and accurately.

[0005]

A man-hour accumulating device of the present invention is an actual man-hour which is obtained by statistically quantifying an input section for inputting a process factor of building construction and a process factor inputted in the input section and multiplying the standard man-hour. And a calculation unit for converting the actual man-hours into a process required time and an output unit for outputting and displaying the process required time obtained by the calculation unit. The output display of the output unit represents the process required time by the length of a line segment that extends on the axis with a time scale and has a start point as a construction start time and an end point as a construction end time.

[0006]

[Function] The process factors in the above means are mainly building conditions, site conditions, management conditions, and construction conditions. In order to quantify these statistically, for example, the general tendency that the proficiency level improves as the number of years of work experience of workers increases It is conceivable that the proficiency level of each worker is aggregated for each frequency to create a frequency distribution chart and the deviation of the frequency distribution chart is replaced with a coefficient. On the other hand, the standard man-hours mentioned above are, for example, standard man-hours set according to conditions such as specifications, work amount, difficulty, scale efficiency, etc., and the standard man-hours are executed by a plurality of workers to make the actual man-hours of each worker. It is conceivable that the average value of these values is calculated by aggregating.

According to the man-hour integrating device of the present invention, the process factors can be quantified as described above, and the standard man-hours can be multiplied by the process factors to calculate the actual man-hours. It is not necessary to comprehensively judge many process factors based on the experience and intuition of the person. Further, the process required time obtained by the calculation unit is represented by the length of a line segment that extends on the axis with a time scale and has a start point as a construction start time and an end point as a construction end time, thereby The working hours of workers can be understood at a glance. Therefore, even if the building is built through a complicated construction process, we will arrange the workers necessary for construction and estimate the construction cost.
Furthermore, profit calculation and the like can be performed quickly and accurately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A man-hour integrating device according to an embodiment of the present invention is shown in FIG.
Input section 1 for inputting process factors of building construction, as shown in
And a calculation unit 2 for statistically quantifying the process factors input to the input unit 1 to calculate the actual man-hours by multiplying the standard man-hours and converting the actual man-hours into a process-required time; An output unit 3 for outputting and displaying the required process time, a storage unit 4 for accumulating statistical data, and a printer 5 for printing the output contents of the output unit 3 are provided. The input unit includes a keyboard and a mouse (not shown). The output unit 3 is a CRT screen. The storage unit 4 stores information using a floppy disk or the like as a medium.

The process factors mainly include building conditions, site conditions, management conditions and construction conditions. In detail, the building conditions include building scale, utilization effect, specifications, number of floors, roof slope, main / sub / accessory, and the site conditions are temporary conditions, surrounding environment, commuting distance,
Meteorological conditions and the like, management conditions such as organization, design, material arrangement, construction information, and construction guidance, and further construction conditions include years of experience, age structure, employment form, setup superiority and inferiority, Physical strength, teamwork, etc. can be mentioned. In addition to the above, the process factors are classified into peripheral environment, site conditions, contractor, incidental work amount, work efficiency, season, building, work, production, construction and other factors as shown in FIG. You can also In addition, in FIG.
As indicated by the ruled line drawn from the entry column for each factor, factors related to the building include, for example, structural system, snow cover classification, model, fire protection classification, number of floors, construction methods such as manual assembly and compounding, and roof slope.

In order to quantify these statistically, for example, a general tendency that the skill is improved as the number of years of practical experience of a worker is expressed as a proficiency level. This proficiency level is a numerical value that increases or decreases according to the deviation of the frequency distribution chart shown in FIG. That is, the average level of proficiency is set to 1 and is replaced with a coefficient such that the man-hour decreases as the proficiency level improves.

In addition to this, the general tendency that the physical strength of the worker is remarkably decreased and the work efficiency is decreased as the worker ages is expressed as age efficiency. As shown in FIG. 4, this age efficiency is improved by setting the work efficiency of a 35-year-old worker as 1 in the frequency distribution chart in which the work efficiency of each worker is aggregated by age for a large number of workers. It is replaced with a coefficient that decreases as Furthermore, as a scale for comparing the setup of construction and the superiority and inferiority of planning, FIG.
Based on the frequency distribution chart in which the results of a plurality of workers are aggregated as shown in (1), the number of workers at the average level is set to 1, and a coefficient is introduced so that the man-hour decreases as the number of good performers increases.

[0012] Further, if the building becomes large in scale, the construction period will be remarkably prolonged, but conversely, it may be possible to facilitate the loading of building materials and increase the working space due to an increase in the floor area, etc. The scale efficiency refers to the tendency that construction can be performed more efficiently in such a large-scale building than in a small-scale building such as a detached house. This scale efficiency is shown in Figure 6.
As shown in, in the frequency distribution chart that aggregates the work efficiency at each construction site by floor area for a large number of construction sites, the construction site with a floor area of 135 m ^{2 which} is relatively in demand is 1 It is replaced with a coefficient such that the unit man-hour decreases with increasing.

Further, the tendency that the construction work becomes more difficult on the sloped roof as compared with the flat roof is expressed as the slope difficulty. This grade difficulty level is based on the aggregate work efficiency for each construction site by comparing the required time for the process and the number of workers required for construction, etc., for a large number of construction sites on a pitched roof and a flat roof. In addition to creating the frequency distribution chart shown in Fig. 7, the roof gradient, which is often used in general residential areas, is set to 1 in the frequency distribution chart and replaced with a coefficient that increases the man-hour as the gradient increases. is there.

The work efficiency of the worker is greatly affected by the temperature, and the tendency that the worker can perform the work most efficiently in the temperature range of 14 to 21 degrees Celsius is shown as the work effect by the temperature. In the frequency distribution chart shown in FIG. 8, the work effect due to this temperature becomes approximately 1 in the range of 14 to 21 degrees Celsius, and is replaced with a coefficient such that the man-hour increases or decreases as the temperature rises or falls from this temperature range. It is a thing. Furthermore, as a measure for comparing the superiority and inferiority of crane operation, based on the frequency distribution chart that aggregates the skill levels of workers as shown in FIG. The crane operation effect is introduced so that

On the other hand, the above-mentioned standard man-hours are set by standard man-hours according to conditions such as specifications, work amount, difficulty, scale efficiency, etc. The man-hours are totaled and the average value of these is calculated. The frequency distribution table, the coefficient, and the standard man-hours illustrated above are respectively stored in the storage unit 4 as statistical data, and can be called to the calculation unit 2 when necessary. In addition, the process factors that are not illustrated are also quantified based on the statistics collected in advance as described above.

According to the man-hour accumulating device configured as described above, when various process factors are input to the input unit 1 on the basis of materials such as a construction drawing to be built and a management ledger of a worker prepared in advance. The statistical data corresponding to the input process factor is called from the storage unit 4 to the calculation unit 2. Then, the calculation factor 2 quantifies the process factors based on the statistical data. That is, if the worker's age is 3
If the person is 5 years old, the coefficient value becomes 1. Further, the actual man-hours are calculated by multiplying the quantified process factors by the above-exemplified standard man-hours.

Therefore, even in the case of a building that is constructed through a complicated construction process, without the reliance on the experience and intuition of a skilled worker, arrangements of workers necessary for construction construction and estimation of construction costs including incidental construction, Furthermore, profit calculation and the like can be performed quickly and accurately. In addition, it is possible to objectively grasp the total process even in a building where the construction process is extremely complicated, and the proficiency level of each worker based on the proficiency level of the work worker, the temperature difference due to the season, or the site conditions. Since it can be digitally grasped, it can also be used to create materials for employment measures.
Further, even when a subcontractor or the like is requested to carry out the construction, the construction period, construction cost, etc. can be accurately grasped.

Further, the actual man-hours are converted into the process required time, and the process required time is extended on the axis with a time scale as shown in FIG. 10 and the starting point is the construction start time and the end point is the construction end time. It is possible to output and display from the output unit 3 as a process chart represented by the length of the line segment. Further, the process table can be printed by the printer 5. As a result, it is possible to understand at a glance, for example, what time of the month and what time is required for the work of the building framework.
