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 for assigning the content to work for each of the mold carpenter worker and the reinforcement worker to construct the reinforced concrete frame in the construction of apartment buildings, so that the worker can efficiently move to the same floor or the next floor, Provide construction planning and staffing methods that allow for rapid and repetitive work in the same framework plane area or location.

According to the Ministry of Land, Infrastructure and Transport's 2017 housing permit, the apartment has 470,000 households. The apartment construction consists of 2 to 6 buildings, with a maximum of 20 buildings.

Apartment types are divided into tower type and plate type. Recent types of plaques are straight or 'a' or 'b'. The number of households in one floor is 4th generation to 6th generation. The households are arranged in the south direction and consist of staircases and elevators. The core is located in the north and is usually two.

The plate type has a lot of space placed on the front, so it is excellent in daylighting and sunlight, facing the living room and kitchen, which is favorable for direct wind. Most apartments are designed as 'ㄱ' because the number of furniture can be maximized when the apartment building is composed of 'ㄱ' rather than 'ㅡ'.

The layout of the plane is a V-shape where the corners of the 'a' are arranged in the south direction, so that in the morning, the right part of the east receives sunlight and in the afternoon the west, the other half, receives sunlight.

The cores of staircases and elevators should be placed north so that they do not block view or sunlight.

The most bird's eye view or the floor plan of the apartment shows the arrangement as above.

The structural type is reinforced concrete structure, vertical load is wall structure supported by wall, and slab is flat slab without beam.

The construction of the apartment is carried out in the order of the construction of the foundation mat after the digging, the completion of the basement floor, and then the construction of the ground concrete reinforced concrete finishing and finishing work. The height of the double-layer framing construction is 20 to 49 stories.

The ground frame has the characteristics of a serial construction method that has a clear structure of the preliminary work and the subsequent work of constructing the 11th floor after constructing the 10th floor after constructing the lower floor.

Since the framework is the skeleton of the building, the construction period is long, expensive, and a large number of workers are involved.

Such a frame construction is usually carried out by manpower takes 6 to 8 days in one floor construction. The work order for one floor consists of feeding, wall column reinforcement, wall column formwork, slab club and slab formwork, slab reinforcement, concrete pouring and curing.

Here, the mold is constructed by a carpenter worker, a mold worker, and functions as a box as formwork and plywood, and the frame is completed by adding reinforcing bars and pouring concrete into it.

Since concrete is poured on the last day, the previous stages are the main tasks of the formwork and reinforcing work, which is mostly carpenter work. The rest is electricity and equipment work.

In the fourth generation of a single-floor apartment, about 150 workers are employed. The largest number of double molder (carpenter) workers, followed by the rebar workers, combined with the mold worker and reinforcing workers occupy about 70% to 80% of the total.

Therefore, it can be seen that the frame construction is produced by the construction worker and the rebar worker.

On the other hand, in the case of a 10-day cycle for the 10-story frame construction of 101-dong, the molder and the rebar worker have an irregular structure.

On the 6th day, the last day, concrete is poured, so the mold or reinforcement work is completed by the 5th day, and on the 6th day, there are no more than 100 molders and reinforcement workers.

From the first to the fifth day, many or less irregular work is carried out in the form or reinforcing bar work, so workers are irregularly dispatched.

As a result, the remaining workers will work in another Dong-dong 102 building or another nearby site.

According to these characteristics, unlike the manufacturing industry, it is very important for a worker manager to mobilize or manage a worker because construction sites must be arranged according to irregular worker demand by date.

However, the worker manager's placement of the mold and the rebar worker is currently being carried out based on his own experience or know-how.

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

As apartments vary in plan shape for each site or building, errors can increase when the experience is applied.

Since the daily number of people is irregular, it is possible to minimize the loss of personnel or labor costs by efficiently managing the necessary or remaining personnel, but the method of calculating the number is used.

Existing papers and studies on apartment worker placement and circulation suggest the order of cycle cycles by apartment building, but there is no way to suggest concrete molds and the number of rebar workers based on apartment floor, rebar and concrete quantity.

Formwork and reinforcement workers are composed of several teams and perform work tasks individually, but there is no specific way of moving individual workplaces or building parts.

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

In collecting the work productivity results and reflecting them in the plan how much construction is done per day, there is no individual analysis method or embodiment for each construction worker.

Frame and rebar workers are working on specific members for each individual, but they do not allocate their own structure to each other in consideration of their capabilities.

Therefore, in the present invention, in connection with such a technique, in the apartment frame construction consisting of a plurality of buildings, the molder and the reinforcement worker to improve the work productivity of the individual work place movement path arrangement plan analysis method.

The present invention has been made to solve the problems according to the prior art as described above, and provides a method for assigning a work place, work object and quantity for each individual to the mold and reinforcement workers in the construction of the apartment frame, and analyzing the performance do.

In order to achieve the above object and to solve the above-mentioned problems of the prior art, in the apartment frame construction according to the present invention, the individual work assignment method and apparatus of the mold and reinforcement worker calculates the formwork and the reinforcement quantity of each floor, Workers are assigned to columns (walls) in consideration of work productivity, workers are assigned based on the room or area of the slabs, and when the work is finished, a path is moved to the next floor or another zone to correspond to each member. The worker is calculated.

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

You can plan in detail who and when to construct each column or wall in a frame.

Work time is objective and accurate because it is calculated by dividing the quantity of members by the worker's daily productivity.

Workers can work efficiently because they can know in advance the location and time of work on each floor and the quantity to be worked in advance. You can also see how much you have built and know your daily or wage trends in advance.

Worker managers who assign workers can assign workers and perform performance measurement scientifically, taking into account their individual capabilities. This allows for more efficient worker assignment on the next floor or other construction, reflecting the characteristics of the worker.

The contractor can identify the problems in detail and systematically by comparing the construction performances with the planned worker assignments, so it is easy to identify the problems and establish countermeasures.

For example, if the work of 101-901 is delayed compared to other areas, the entire schedule is affected, so that you can know who is assigned to the room, analyze the productivity, and add or replace workers. This becomes quick and easy.

The work plan of each worker is combined to establish a construction plan for each team, and the construction plan for the entire construction is accurately established. Accordingly, various simulations can be used to create construction methods that reduce labor costs by allocating air shortening and the minimum number of workers.

By assigning to tasks that the worker is familiar with or familiar with, and assigning them to be able to work repeatedly, the learning or learning effects can be exerted. This can increase work productivity by more than 10%.

If work productivity increases, construction time can be shortened by the same personnel or construction labor cost can be reduced.

Reduces manpower and time lost due to irregular worker launches or unreasonable assignments.

As workers work in the same and repetitive manner, they become more aware of the work of the asset, improving quality and reducing the risk of safety accidents.

The construction company or reinforced concrete construction company using the above-mentioned worker assignment method can quickly and accurately assign and manage workers compared to other competitors, and can shorten the number of construction days and reduce labor costs, thereby increasing the competitiveness of order and survival of apartment framing. .

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

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

Referring to FIG. 1, the construction method analysis apparatus 10 for individual work assignment according to the present embodiment includes a control unit 11, an architectural drawing database 12, a reference layer planar tool division database 13, and material quantity data. A base 14, a worker productivity database 15, a schedule table database 16, and a worker assignment database 17 are included.

The control unit 11 calculates the quantity (quantity) of material parts for each tool according to the tool division on the reference layer planar tool division database 13 from the material quantity database 14, and the worker productivity database 15 for each worker. ), The work time for each member (column, wall, slab for each room) is calculated, the worker movement path is calculated from the process table database 16 to the next tool or layer, and the calculated result is sent to the worker assignment database 17. Save it.

For example, the control unit 11 stores the building drawings, the structural drawings, and the BIM drawings in the building drawing database 12 in the construction of four 35-story apartment buildings. The reference layer plane is divided into two, A and B.

Room 9, Room 901, 101, Living Room, Kitchen, Study Room, Small Room, Toilet, Toilet 1, Area of Porch Porch, Formation of Reinforcement and Reinforcement of Column Wall Slab. The outermost inner chamber consists of four walls and one ceiling slab, and the quantity of wall reinforcement and wall frame for the construction of four walls is calculated.

The slab mold and the number of reinforcing bars for constructing slabs, which are floors, are also calculated.

The worker is assigned to the quantity for constructing the inner wall 1, and the working time is calculated by dividing the quantity by daily productivity or productivity per hour. Productivity uses the worker productivity database 15 for each worker.

When the worker assignment for the 901 households is completed in the above order, the worker is assigned to the 902 households next to the household. And the assigned number 1 for the core consisting of stairs and elevators. Next, 903, 904, and Core 2 are also assigned in the same manner as in 901.

When the process table is read from the process table database 16 and the allocation to the 9th floor is completed, the next 10th floor is allocated. The workers are assigned from the 11th floor to the 35th floor, and the result is stored in the worker assignment database 17.

The architectural drawing database 12 stores architectural drawings, structural drawings, and BIM. Calculating workforce and material quantities include floor plans, cross sections, floor heights, and column wall dimensions. The construction site is constructed in accordance with the drawings, so the drawings are already completed in CAD, etc. before the start of construction.

The reference layer plane division database 13 stores information obtained by dividing one layer into two tool zones in general.

Here, the criterion for tool division is the unit to cast concrete. For example, if building 101 consists of four generations and two cores, tool A, which includes 901, 902, and core 1, will cast concrete on Monday and the rest of tool B (903, 904, core 2). Times) pour on Wednesday.

The material quantity database 14 stores quantity information of the form of the wall and the slab and the reinforcing bars for each room. For example, it stores information about the number of formwork and reinforcing bars of slabs and walls on the porch and the walls of the entrance porch.

The quantity corresponds to an existing task that is generally calculated by a professional company.

The worker's individual work productivity database 15 stores information about a person's daily construction ability or construction capability per hour of the mold worker and the rebar worker.

For example, Hong Gil-dong, the first reinforcing bar worker, has recorded 1.2 tons of wall reinforcing bars per day and 1.5 tons of slab rebars.

The schedule table database 16 is a construction schedule showing a work schedule for each floor, and includes a frame construction and a reinforcement construction.

For example, it displays the date and time information on the construction of reinforcement and reinforcement of walls and slabs on the porch, the room, the living room, the kitchen, the study room, the bathroom, the bathroom, the bathroom and the porch.

The worker assignment database 17 stores a result of assigning a worker to each member of each room. For example, it describes the contents of which worker should construct the inner wall No. 1 of building 101, 9, 901. Reinforcement wall No. 1 can be constructed in one day, so we assign Hong Gil-dong, the reinforcement worker No. 1.

2 to 4 is a flow chart of the construction method analysis method for individual work assignment according to an embodiment of the present invention.

First, referring to FIG. 2 according to an embodiment, an architectural drawing, a structural drawing, and a BIM drawing of an apartment frame are stored (S10). Each floor of the apartment is divided into two zones (S20). For example, in a flat apartment of a 'b' shape, it is divided into two zones A (101, 102, core 1) and B zone (103, 104, core 2).

A process table for the divided zones A and B is prepared and stored in the process table database 16 (S30).

Building 101 and 102 are paired and divided into tool A. The work days of each floor in zones A and B are 4 days, and zones A and B are 2 days apart. Prepares a timetable that progresses by one day or three days. The minimum time unit of the timetable is hourly or at least AM afternoon.

The first day includes the filling, rebar lifting, wall reinforcement, and wall frame installation work for Building 101, Zone A, 101, and 102.

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

For example, the number of formwork and reinforcing bars is stored for each wall and slab for the living room, kitchen, study room, small room, toilet, toilet, and porch.

In addition, the worker is assigned to each member by dividing the number of molds and reinforcing bars for each room by the worker productivity of the work productivity database 15 for each worker (S50).

For example, if the 1st and 2nd reinforcing bars are 1,000kg each of the four walls in the main room of 101-101, and the productivity of Hong Gil-dong, the reinforcing worker 1, is 1,500kg per day, the wall 1 and the reinforcing worker 1 will be wall 1 Allocate 100% at time, 50% at Wall 2, and the next two rebar workers at 50% of Wall 2.

In the same way as above, the floor and the reinforcement workers are assigned in the order of No. 101 to No. 104 to complete the first floor assignment.

Next, the worker is assigned to the second floor, which is the upper floor, in the same manner as in the first floor (S60). The final floor is assigned to the 35th floor to complete the allocation of the frame.

When the assignment is completed, the worker required trend is calculated by calculating the required number of workers on a morning and afternoon basis for each time zone (S70).

When the number of workers is determined as a result of determining the number of workers (S80), the process of calculating the number of people by applying another assignment plan is repeated (S90).

Simulation by worker simulation for the number of cases

The quantitative analysis index indicator for the number of people, the working time is calculated (S100).

After determining the most excellent worker assignment among these is selected as the first proposal (S110).

When the first proposal is selected in the above step, the member list and the corresponding worker list are displayed on a table or a plan view so as to be easily understood and managed (S120).

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

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

The following describes the steps to collect the construction results according to the start of construction.

When the construction of the first floor 101 building 101 is started, the worker is put into the first day, and the work results are collected in the morning afternoon or the first day, and then stored in the work productivity database 15 for each worker (S140).

When the results are collected, the difference is calculated by comparing the productivity value of the planning step of S50 and the performance productivity value of the step S140 (S150).

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

According to the results of the analysis of the productivity difference, the productivity difference (working rebar quantity difference) of the individual worker is calculated to determine the less than worker and the excess worker (S160).

In the case of the construction zone that is not met, additionally inject or replace workers to comply with the planned construction schedule and working time for each construction zone (S170).

In the above manner, the process of comparing and analyzing the performance compared to the plan and correcting the difference is continuously and systematically repeated (S180).

The individual and total productivity analysis is performed for several floor units, five or ten floor units, and when the framework is completed (S190).

Through the above process, the construction method was analyzed for the process of building one floor one by one while moving the 101 and 102 areas.

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

5 is a construction overview of a plate-like apartment according to an embodiment of the present invention. In the bird's-eye view, the number of apartments is 20 apartment buildings of over 3,000 households. In the central layout, the plane is shaped like 'a' and consists of four households and two cores. The bottom generation floor plan is Bedroom 1 (room), small living room, kitchen and bathroom.

The structure is reinforced concrete wall structure and flat plate slab.

Figure 6 is a skeleton construction process table according to an embodiment of the present invention. Each building is divided into Zone A (2nd Generation and Core No. 1) and Zone B (2nd Generation and Core No. 2). Zones A and B are 4 days cycles per floor, with 2 days difference. Buildings 101 and 102 are divided into section A and run one or three days apart.

For example, Building 101 5-F Zone A (501, 502, Core 1) will be poured concrete on Monday, and Building 102 5-F Zone A (501, 502, Core 1) will be poured on Tuesday. Building 5, B-floor B (503, 504, Core 2) will be concrete on Wednesday, and building 102, 5F B-zone (503, 504, Core 2) will be poured on Thursday. do.

As a detailed process table at a lower level than FIG. 6, a detailed process table for each member for each generation for each zone is created and stored separately.

Figure 7 shows the numbering for each wall member of the 101-501 generation, in accordance with an embodiment of the present invention on a household plan view. Home Living Room Kitchen Study Room Small Room Toilet 1 Toilet 2, wall and slab formwork and reinforcement list for porch.

FIG. 8 illustrates the rebar quantity for each wall member for each room of each member of FIG. 7 according to an exemplary embodiment of the present invention. In addition, the number of slab reinforcing bars, wall molds, and slab molds is calculated.

The quantity for each member is generally calculated by a professional company for integration, but it is necessary to divide it again by generation and member because it is aggregated by floor by material type and standard.

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

The productivity data of the molder is also calculated and managed separately.

10 is a view showing the contents of assigning an operator to each member of FIG. 8 according to an embodiment of the present invention. The reinforcement worker No. 1 Hong Gil-dong is assigned to the house wall 01, and the reinforcement worker No. 1 Hong-gil-dong and the rebar No. 5 worker are assigned to the kitchen wall 04 at the same time.

The molder will be assigned to each room in the same way.

11 is a view showing a movement route of a daily worker according to an embodiment of the present invention. Reinforcement worker No. 1 Hong Gil-dong is working on 501, A zone 101, on the first day, 102 A on zone 501, on the second day, and 503 on B zone 101 on the third day.

Figure 12 shows the difference with the performance compared to the plan according to an embodiment of the present invention. Reinforcement worker No. 1 Hong Gil-dong worked in Room 501, Building 101, on Day 1, but failed to construct the planned quantity. This allows managers to add additional workers, direct night work, or replace workers.

The cause and problem can be accurately identified by individual, so that necessary actions can be taken quickly and easily. As a result, the ability to proceed with the construction according to the set schedule.

FIG. 13 is a diagram showing the daily shift of required number of reinforcing worker of two buildings, which combined 101 and 102, according to an embodiment of the present invention. The number of people required is equal, and if the number of people left in building 101 on Monday is working in 102, the opposite is the case. On Tuesday, the number of people remaining in building 102 is working in 101, showing the overall balance.

This equal demand for workers reduces labor loss, reduces labor costs, secures quality, prevents safety accidents, shortens construction periods and working hours, and improves productivity through learning effects as soon as the same members are constructed. .

The worker assignment method for each team can be applied from the above-mentioned individual worker assignment method, and a reinforced concrete construction company can perform efficient worker assignment and operation management using the concepts and ideas.

As described above, an object of the present invention is to provide a method for operating a worker who can establish a work plan for each worker, which is the minimum unit of reinforcing bar and frame worker, which is the core of apartment framing.

It is to find the optimal manpower management method by analyzing the work assignment method for the optimal construction method by determining the working time and order according to the mold and the number of reinforcing bars and the individual capacity of the worker to extinguish it.

In the present embodiment, the method is applied to the flat-type apartments, but the construction engineers will clearly know that the above-described methods can be applied in the same manner or similar to the construction of the tower-type apartments, the residential complex, and the officetel framing. .
