Description

{An apparatus and method for analyzing a working area and route of form worker and rebar worker at a housing construction}

The present invention relates to a method of assigning work to each individual frame carpenter and rebar worker constructing a reinforced concrete frame in the construction of an apartment complex, so that workers can efficiently move to the same floor or the next floor, Provides a construction plan and personnel input method that can work quickly and repeatedly in the same frame plan area or location.

According to the Ministry of Land, Infrastructure and Transport's 2017 housing licensing announcement, there are 470,000 apartments. Apartment construction consists of 2 to 6 buildings, and there are also large complexes with up to 20 buildings.

Apartment types are divided into tower type and plate type. The latest types of plate shapes are straight or 'ㄱ' or 'ㄴ' shaped. The number of households on one floor is 4 to 6 households. The units are arranged in the south direction, and the core consisting of the staircase and elevator is located in the north, and there are usually two.

The plate type has a lot of space in the front, so it has excellent lighting and sunlight, and the living room and kitchen face each other, which is advantageous for cross ventilation. Most apartments are designed in an 'ㄱ' shape because the number of households can be maximized when the apartment building is structured in an 'ㄱ' shape rather than in a 'ㅡ' shape.

The layout of the floor plan represents a V-shape with the corners of the letter 'L' facing south. This is to ensure that the right eastern half receives sunlight in the morning and the western half receives sunlight in the afternoon.

The core of the staircase and elevator is placed on the north side so as not to block the view or sunlight.

If you look at most apartment bird's eye views or building layout plans, they are laid out in the form above.

Looking at the structural type, it is a reinforced concrete structure, the vertical load is a wall structure supported by the wall, and the slab is a massless flat slab without beams.

Apartment construction is carried out in the following order: excavation, construction of an apartment foundation mat, completion of the basement floor, and reinforced concrete framing and finishing work on the ground floor. The height of the ground floor framing construction ranges from 20 to 49 floors.

The above-ground frame has the characteristics of a serial construction method with a clear structure of preceding and succeeding works, such as constructing the lower floor, then moving up to the upper floor, constructing the 10th floor, and then constructing the 11th floor.

Frame work is the framework of a building, so the construction period is long, construction costs are high, and many workers are involved.

This type of framing work is performed by manpower, and it usually takes 6 to 8 days to construct one floor. The work order for one floor consists of filling, wall column reinforcement, wall column form, slab framing and slab form, slab reinforcement, concrete pouring, and curing.

Here, the form is constructed by carpenters and form workers, and functions as a box as formwork and plywood. The frame is completed by placing rebar in it and pouring concrete.

Since the concrete is poured on the last day, the previous steps are mostly carpentry work, such as formwork and rebar work. The rest includes electrical and equipment work.

In the case of 4 units on one floor of an apartment, about 150 workers are employed. Among these, form workers (carpenters) are the most numerous, followed by rebar workers. Together, form workers and rebar workers account for about 70% to 80% of the total.

Therefore, it can be said that frame work is constructed and produced by form workers and rebar workers.

Meanwhile, when the construction period for the 10th floor of building 101 is a 6-day cycle, the number of form workers and rebar workers required per day is irregular.

Since concrete is poured on the 6th day, which is the last day, the form and rebar work is completed by the 5th day, so there is no need for more than 100 form workers and rebar workers on the 6th day.

From the 1st to the 5th day, the formwork or rebar work progresses irregularly, with more or less work being done, so workers are also dispatched irregularly.

Accordingly, the remaining workers will work in another building, Building 102, or at other nearby sites.

According to these characteristics, unlike manufacturing, construction sites must assign workers according to irregular demand for workers on a daily basis, so worker managers' ability to plan and manage worker mobilization is very important.

However, the task of assigning form and rebar workers to worker managers is currently being carried out based on their own experience or know-how.

The existing problems in existing worker placement work are as follows.

Apartments have different floor plans for each site or building, so errors may increase when applying experience.

Since the number of people per day is irregular, the loss of personnel or labor costs can be minimized by efficiently managing the required number of people or the remaining number of people. However, the manual calculation method is used to calculate this.

Existing papers or studies on apartment worker placement or circulation present the circulation cycle order for each building, but there is no way to present the specific number of form and rebar workers based on the apartment plan or the quantity of rebar and concrete.

Frame and rebar workers are organized into several teams and perform work duties individually, but there is no specific method for each team or individual to move to a work location or what members (columns) to construct.

There are no examples of analysis or quick and accurate calculations to minimize the remaining personnel, personnel losses, and labor costs due to irregular worker dispatch.

In collecting work productivity performance, such as how much construction a worker does per day, and reflecting this in the plan, there is no analysis method or example for individual frame construction workers.

Frame and rebar workers individually work on specific members, but the structural work that workers need to construct (e.g., the 10th floor of Building 101) is not assigned to each individual in consideration of their capabilities.

Therefore, in relation to this technology, the present invention seeks to devise a method for analyzing the movement path arrangement plan of each worker's individual work location, which can increase the work productivity of form workers and rebar workers in apartment framing construction consisting of multiple buildings.

The present invention was created to solve the problems caused by the prior art as described above, and provides a method of allocating work locations, work objects, and quantities to each individual and analyzing performance by frame and rebar workers in apartment framing construction. do.

In order to achieve the above-mentioned purpose and solve the problems of the prior art described above, the method and device for assigning individual work to formwork and rebar workers in apartment framing construction according to the present invention calculates the quantity of formwork and rebar for one floor, and calculates the amount of formwork and rebar for each floor. Workers are assigned to columns (walls) in consideration of work productivity, workers are assigned based on the room or area of the slab, and when the work is completed, the route to the next floor or other zone is designated to respond to each member. Workers are produced.

According to the present invention, the following effects can be expected.

It is possible to plan in detail who will construct each column or wall of the frame work, when, and in what order.

Working hours are objective and accurate because they are calculated by dividing the quantity of absences by the worker's daily work productivity.

Individual workers can work efficiently because they can accurately know the work location, time, and quantity of work on each floor in advance, and thus know future work in advance. In addition, you can know the quantity of construction and know your daily wage or wage trend in advance.

Worker managers who assign workers can assign workers by considering each worker's capabilities and measure performance scientifically. Accordingly, more efficient worker assignment can be made to the next floor or other construction work by reflecting the worker's characteristics.

By comparing the construction performance against the planned worker allocation, the construction company can learn about problems in detail and systematically on an individual basis, making it easier to identify problems and establish countermeasures.

For example, if work in room 901 of building 101 is delayed compared to other areas and the overall schedule is affected, you can find out who the workers assigned to the master room are, analyze productivity, and establish countermeasures such as adding or replacing workers. This becomes quick and easy.

By combining the work assignments of individual workers, a construction plan is established for each team, and the construction plan for the entire construction company is accurately established. Accordingly, through various simulations, it is possible to create a construction method that reduces labor costs by shortening the construction period and assigning the minimum number of workers.

By assigning workers to tasks they know well or are familiar with, and assigning them to work repeatedly, a learning or habituation effect can be achieved. As a result, work productivity can increase by more than 10%.

As work productivity increases, construction time can be shortened with the same number of people or construction labor costs can be reduced.

Reduces manpower and time loss due to irregular worker dispatch or unreasonable assignment.

As workers perform the same, repetitive tasks, they become more familiar with the asset's operation, improving quality and reducing the risk of safety accidents.

Construction companies or specialized reinforced concrete construction companies that use the above worker assignment method can assign and manage workers more quickly and accurately than other competitors, shorten the number of construction days, and reduce labor costs, thereby increasing the competitiveness of winning orders and surviving in apartment framing construction. .

Hereinafter, the apparatus and method for analyzing the work assignment method for each worker in the frame and rebar construction of apartment framing construction according to the present invention will be described in detail.

Figure 1 shows the overall configuration of a construction method analysis device for individual work assignment according to an embodiment of the present invention.

Referring to FIG. 1, the construction method analysis device 10 for individual work assignment according to this embodiment includes a control unit 11, an architectural drawing database 12, a reference floor plane tool division database 13, and material quantity data. It includes a base (14), an individual worker's work productivity database (15), a schedule database (16), and a worker assignment database (17).

The control unit 11 calculates the quantity (quantity) of material members for each tool according to the tool division on the reference layer plane tool division database 13 from the material quantity database 14, and calculates the quantity of material members for each tool from the material quantity database 14 and the work productivity database 15 for each worker. ), the working time for each member (column, wall, slab by room) is calculated, the worker movement path to the next tool or floor is calculated from the schedule database 16, and the calculated results are stored in the worker assignment database 17. Save.

For example, in the construction of a 35-story apartment building in four buildings, the control unit 11 stores the architectural drawings, structural drawings, and BIM drawings of each building in the architectural drawing database 12. Divide the reference floor plane into two, A and B.

Calculate the area of room 901 on the 9th floor of building 101, living room, kitchen, study room, small room, bathroom 1, bathroom 2, and entrance veranda, as well as the formwork and rebar for the column wall slab. The outermost master bedroom consists of four walls and one ceiling slab, and the quantity of wall rebar and wall form to construct the four walls is calculated.

The quantity of slab formwork and rebar for constructing the slab floor is also calculated.

Workers are assigned for the quantity to construct master bedroom wall 1, and the working time is calculated by dividing the quantity by daily productivity or hourly productivity. Productivity uses the work productivity database (15) for each worker.

Once worker assignment to household 901 is completed in the above order, they are assigned to household 902, which is the next generation. And carry out the assigned core number 1, which consists of stairs and elevators. Next, rooms 903, 904, and core 2 are assigned in the same manner as room 901.

When the schedule is read from the schedule database 16 and assignment to the 9th floor is completed, assignment to the 10th floor is then performed. Then, workers are assigned to the upper floors, from the 11th floor to the 35th floor, and the results are stored in the worker assignment database 17.

The architectural drawing database 12 stores architectural drawings, structural drawings, and BIM. To calculate the number of workers and materials, include floor plans, cross-sections, floor heights, and pillar wall dimensions. Construction sites are constructed according to drawings, so the drawings are already completed in CAD, etc. before construction begins.

The reference floor plane division database 13 generally stores information about dividing one floor into two tool zones.

Here, the standard for tool division is the unit for pouring concrete. For example, if Building 101 consists of 4 households and 2 cores, the concrete for Tool A, which includes Units 901 and 902 and Core No. 1, is poured on Monday, and the remaining Tool B (No. 903, No. 904, Core 2) is poured on Monday. number) will be poured on Wednesday.

The material quantity database 14 stores quantity information of walls and slabs and reinforcing bars for each room by household. For example, in room 901 on the 9th floor of Building 101, information about the quantity of molds and reinforcing bars for the walls and slabs for the master bedroom, living room, kitchen, study room, small room, bathroom 1, bathroom 2, and the entrance veranda is stored.

The above quantity corresponds to existing work generally calculated by companies specializing in integration.

The worker's individual work productivity database 15 stores information on the daily or hourly construction ability of each individual form worker or rebar worker.

For example, Hong Gil-dong, rebar worker number 1, shows the ability to construct 1.2 tons of wall rebar per day and 1.5 tons of slab rebar according to past records.

The schedule database 16 is a construction schedule showing the work schedule for each floor and household and includes formwork and rebar work.

For example, it shows the date and time information regarding the construction of the formwork and rebar for the walls and slabs for the master bedroom, living room, kitchen, study room, small room, bathroom 1, bathroom 2, and the entrance veranda in room 901 on the 9th floor of Building 101.

The worker assignment database 17 stores the results of assigning workers to absences by building, floor, household, and room. For example, it indicates which worker should construct wall number 1 in the master bedroom of room 901 on the 9th floor of Building 101 and when. Since the No. 1 rebar for the master bedroom wall can be constructed in one day, Hong Gil-dong, the No. 1 rebar worker, is assigned.

2 to 4 are overall flowcharts of a construction method analysis method for individual work assignment according to an embodiment of the present invention.

First, referring to FIG. 2 according to one embodiment, the architectural drawing, structural drawing, and BIM drawing of the apartment frame are stored (S10). One floor of each apartment building is divided into two zones (S20). For example, in an 'ㄱ' shaped flat apartment, it is divided into two: Zone A (No. 101, No. 102, Core No. 1) and Zone B (No. 103, No. 104, Core No. 2).

A schedule for the divided A zone and B zone is created and stored in the schedule database 16 (S30).

Buildings 101 and 102 are paired and divided into section A, the number of working days for one floor in zone A and zone B of each building is 4 days, zone A and zone B are carried out 2 days apart, and building 101 and 102 are divided into sections. Creates a schedule that progresses by 1 day or 3 days. The minimum time unit of the schedule is by time zone or at least morning and afternoon units.

Day 1 includes filling, lifting rebar, installing wall rebar, and installing wall frame for Building 101, Zone A, No. 101, No. 102, and Core No. 1.

Next, the quantity of frames and reinforcing bars for each member in each room is calculated and stored in the material quantity database 14 (S40).

For example, the quantity of formwork and rebar is stored for each wall and slab for the master bedroom, living room, kitchen, study room, small room, bathroom 1, bathroom 2, and entrance veranda in building 101, room 101.

Then, the quantity of frames and reinforcing bars for each member in each room is divided by the worker productivity of the individual worker work productivity database (15) to assign a worker to each member (S50).

For example, among the four walls of the master bedroom of building 101, number 101, if the rebar for walls 1 and 2 is 1,000 kg each, and the productivity of Hong Gil-dong, the rebar worker No. 1, is 1,500 kg per day, then the productivity of rebar worker No. 1 is 1,500 kg per day, and the rebar worker No. 1 is placed on wall 1. After allocating 100% to Wall No. 2 and 50% to Wall No. 2, rebar worker No. 2 is then assigned to the remaining 50% of Wall No. 2.

In the same manner as above, frame and rebar workers are assigned in the order from No. 101 to No. 104 to complete the assignment of one floor.

Next, workers are assigned to the upper second floor in the same manner as the first floor (S60). And by completing the allocation to the 35th floor, which is the last floor, the allocation for the framing work is completed.

Once assignment is completed, the number of workers required is calculated in the morning and afternoon for each time zone, and the worker requirement trend is calculated (S70).

As a result of judging the trend in the number of workers, if the number of workers is irregular (S80), the process of calculating the number of people is repeated by applying a different allocation plan (S90).

Through simulation of worker assignment plans for a large number of cases, each simulation

Calculate quantitative analysis indices for the number of people required and work hours (S100).

Among these, the best worker assignment plan is judged and selected as the first plan (S110).

If the first plan is selected in the above step, the member list and the corresponding worker list are displayed on a table or floor plan so that they can be easily seen and managed (S120).

Through the above process, a worker assignment plan for each worker was established.

The worker assignment results calculated through the above steps are stored in the worker assignment database 17 (S130).

The following describes the steps for collecting construction performance following the start of construction.

When construction of building 101, room 101 on the first floor begins, workers are assigned on the first day, work performance in the morning and afternoon or on the first day is collected and stored in the work productivity database 15 for each worker (S140).

When the performance is collected, the productivity value of the planning stage (S50) is compared with the performance productivity value of the (S140) stage and the difference is calculated (S150).

And the calculated productivity data is stored in the work productivity database 15 for each worker. The data includes productivity and work time information on location and area information consisting of construction name, building, floor, household, and room name.

According to the results of the analysis of the productivity difference, the difference in productivity of each worker (difference in the number of rebars worked) is calculated to determine which workers are under-performing and those who are over-performing (S160).

Measures are taken to ensure compliance with the construction schedule and work hours planned for each construction zone by adding additional workers or replacing them in construction areas where the work capacity is insufficient (S170).

In the same manner as above, the process of comparing and analyzing performance against plan and correcting for differences is repeated continuously and systematically (S180).

Individual and overall productivity analysis is performed for several floors of framing work, 5 or 10 floors, and the time of completion of framing work (S190).

Through the above process, the construction method for the process of constructing each floor while workers moved between buildings 101 and 102 was analyzed.

The following describes an example of application of the present invention to actual construction.

Figure 5 is an outline of the construction of a plate-type apartment according to an embodiment of the present invention. Looking at the bird's eye view, it is a very large apartment complex with 20 apartment buildings and more than 3,000 households. Looking at the central layout, the floor plan is in an 'ㄱ' shape and consists of 4 apartments and 2 cores. If you look at the floor plan of the unit below, you will see bedroom 1 (main room), a small room, living room, kitchen, bathroom, etc.

The structure is a reinforced concrete wall structure and a mass plate slab.

Figure 6 is a framing construction process table according to an embodiment of the present invention. Each building is divided into Zone A (2nd generation and Core 1) and Zone B (2 households and Core 2), and Zones A and B have a 4-day cycle per floor, with 2 days difference. Buildings 101 and 102 are divided into Section A and are held 1 or 3 days apart.

For example, concrete is poured for Zone A on the 5th floor of Building 101 (Rooms 501, 502, Core No. 1) on Monday, and Zone A on the 5th floor of Building 102 (Rooms 501, 502, Core No. 1) is poured on Tuesday. Concrete will be poured in Zone B on the 5th floor of Building 101 (Rooms 503, 504, Core No. 2) on Wednesday, and Zone B on the 5th floor of Building 102 (Rooms 503, 504, Core No. 2) on Thursday. do.

As a detailed schedule at a lower level than Figure 6, the detailed schedule for each date, zone, generation, and member is created and stored separately.

Figure 7 shows the numbering of each wall member of unit 501 in building 101 according to an embodiment of the present invention on a household floor plan. Includes a list of formwork and rebar members for walls and slabs for the master bedroom, living room, kitchen, study room, small room, bathroom 1, bathroom 2, and the entrance veranda.

Figure 8 shows the quantity of reinforcing bars for each wall member in each room for each member in Figure 7 according to an embodiment of the present invention. In addition, the quantity of slab rebar, wall form, and slab form is calculated.

The quantity for each member is generally calculated by a company specializing in integration, but since it is calculated by layer by material type and standard, it is necessary to divide it again by household and member.

Figure 9 shows individual productivity performance data of workers according to an embodiment of the present invention. The daily productivity data of wall rebar and slab rebar for Hong Gil-dong, rebar worker number 1, is displayed. Some of the productivity data of form workers and rebar workers belonging to a company specializing in reinforced concrete are displayed.

Productivity data of form workers is also calculated and managed separately.

Figure 10 shows the assignment of workers to each member of Figure 8 according to an embodiment of the present invention. Rebar worker No. 1 Hong Gil-dong is assigned to wall number 01 of the master bedroom in room 501 of building 101, and rebar worker number 1 Hong Gil-dong and rebar worker number 5 are assigned to kitchen wall number 04.

Form workers are also assigned to each room in the same manner as above.

Figure 11 shows the daily movement path of a worker according to an embodiment of the present invention. This shows that Hong Gil-dong, rebar worker No. 1, works in room 501, zone A of building 101, on the first day, in room 501, zone A of building 102, on the second day, and in room 503, zone B of building 101, on the third day.

Figure 12 shows the difference between plan and performance according to an embodiment of the present invention. Rebar worker No. 1 Hong Gil-dong worked in room 501, zone A of building 101, on the first day, but was unable to construct the planned quantity. Accordingly, managers can add additional workers, order night work, or replace workers.

Because causes and problems can be accurately identified for each individual, necessary measures can be taken quickly and easily. As a result, the ability to proceed with construction according to the set schedule increases.

Figure 13 shows the trend of the daily number of rebar workers in two buildings, including buildings 101 and 102, according to an embodiment of the present invention. This indicates that the number of people required is equal. On Monday, the remaining people from Building 101 work in Building 102. Conversely, on Tuesday, the remaining people from Building 102 work in Building 101, indicating overall balance.

This equal demand for workers reduces labor costs by reducing worker losses, secures quality, and prevents safety accidents, shortening the construction period and work hours, and improving productivity through learning effects by constructing the same members in a faster time. .

From the above-described individual worker allocation method, the team worker allocation method can be applied, and a construction company specializing in reinforced concrete will be able to efficiently assign workers and manage operations using the above concepts and ideas.

As described above, the purpose of the present invention is to provide a worker operation method that can establish a work plan for each individual worker, who is the minimum unit of rebar and formwork workers, which are the core of apartment framing construction.

The task is to determine the work time and sequence according to the quantity of frames and rebars to be worked on and the individual capabilities of the workers handling them, and to analyze the worker assignment method for the optimal construction method to find the optimal method of manpower management.

In this example, the method was applied to a plate-type apartment, but construction engineers will clearly know that the method can be applied in the same way to tower-type apartments, residential-commercial complexes, and officetels, since the framework work is also constructed using the same or similar methods and order. .
