[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a construction work management system structure.
[0002]
[Prior art]
For example, when building a hull, which is one of large structures, a block in which the entire hull is divided into a plurality of blocks is assembled in advance at the factory, and each block is loaded into a dock or the like and stacked in a predetermined order. Bonding between blocks is performed sequentially. For example, a plurality of blocks located at the bottom of the ship are first placed in the dock and the blocks are joined together, and the blocks are stacked on top of each other to further join each other.
[0003]
In the construction of such a hull, the blocks are mutually joined mainly by welding between members constituting the blocks. Therefore, the main work in the construction of the hull is a welding work by each worker, and this welding work is performed based on the mounting order (mounting schedule) of each block. At the stage of creating the mounting schedule, the amount of work is calculated for each member to be welded based on the design drawing of the block, taking into account the length, thickness, groove, and worker's work posture (welding posture) during welding work. As a result, the total work amount related to the mounting of each block is calculated as the management amount.
[0004]
In the actual work stage, a work schedule is created based on the management amount of each block, and work assignment is instructed to each worker as a work instruction for each work day. Each worker completes the welding work within the day of the instruction at the work location described in the work instruction. Each worker is obliged to report the work at the end of the day's work, and the work progress is managed based on the work report.
[0005]
[Problems to be solved by the invention]
By the way, the above-described conventional technology has the following problems.
(1) Since the calculation of the management amount is performed manually, it takes time and a calculation error is likely to occur.
(2) Since the above-mentioned work instruction is created by hand of the team leader, for example, entry mistakes or omissions are likely to occur, and the contents of the instruction may not be accurately transmitted to the worker. Due to this, it is easy for unfinished work and work delay to occur.
(3) It is difficult to objectively grasp the work ability of each worker, and the work progress is left to the discretion of the team leader and the worker (group member). Therefore, when the work is delayed, the cause (for example, due to the management amount, due to the personnel plan, or due to the ability of the worker) cannot be accurately grasped, resulting in the work delay. It is difficult to take an appropriate response.
(4) Since the work progress is managed by erasing on the work schedule based on the work report from each worker, that is, the work performance is not cumulatively managed, the change status of work progress is accurately determined. It is difficult to grasp.
(5) Since there is nothing that can confirm at a glance the overall progress of work in the hull construction, it is difficult to accurately grasp the overall work progress in the hull construction and take measures against work delays.
[0006]
The present invention has been made in view of the above-mentioned problems, calculates an accurate management amount in a short time, accurately transmits the work contents to each worker, and appropriately manages the work progress. It is intended to be realized.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a construction work management system for a structure according to the present invention will be described with reference to the drawings.
[0021]
In this embodiment, the present invention is applied to construction work management of a hull, which is one of the structures. That is, a plurality of blocks constituting the hull are assembled in advance at a factory, and these blocks are docked. It is related to the work management when building a hull by carrying in and joining together. In this case, first, the blocks located at the bottom of the ship are joined together and the blocks are sequentially stacked on top of each other to construct a hull. In joining between the blocks, specific members (joining target members) of blocks adjacent to each other are welded together.
[0022]
FIG. 1 is a system configuration diagram of this embodiment. As shown in this figure, the construction work management system is composed of a management amount calculation device 1, a higher level management device 2, and a work management device 3 interconnected by a communication line.
[0023]
The managed amount calculation device 1 is provided in the design department of the hull (structure), and the joining between the joining target members based on the three-dimensional shape data relating to the design model of the hull designed in the design department. The amount of work required for this is calculated, and this amount of work is added to the three-dimensional shape data as attribute data of the members to be joined, and output to the upper management apparatus 2 as design data. The managed amount calculation device 1 calculates, for example, a relative angle between a connection side and a horizontal plane at a joining portion of a joining target member based on three-dimensional shape data as a welding posture (joining posture), and the welding posture and the joining portion. A βNL value is calculated using an evaluation function having the shape (plate thickness, groove shape, and weld leg length) as variables. The βNL value calculated in this way is a numerical value indicating a standard work amount (work time) required when welding the joining target members.
[0024]
The upper management device 2 is arranged in a department in charge of production engineering, and relates to a block currently joined from the design data received from the management amount calculation device 1 via a communication line. Only design data (work block design data) is extracted and sequentially provided to the work management apparatus 3. By providing the upper management device 2, only the work block design data related to the actual work currently being performed is supplied to the work management device 3 having a lower processing capacity than the management amount calculation device 1 and the higher management device 2. To do. The management amount calculation device 1 and the upper management device 2 are engineering workstations, for example, while the work management device 3 is a general-purpose personal computer, for example.
[0025]
The work management device 3 is arranged at a work site, and has a function for creating work instructions for each worker and a function for managing work progress. The work management device 3 displays a 3D image of a design model related to a block that is a current work object (joining object) based on the 3D shape data included in the design data, and refers to the 3D image. Thus, a work instruction is created on the basis of the work procedure input by the operator (the work manager such as the head of the work team) and the βNL value of the joining target member included in the design data.
[0026]
In addition, the work management device 3 selects only a joining target member (that is, a member including a βNL value as attribute information) from a three-dimensional image of the design model based on a predetermined operation input. When an operator designates a worker and a joining target member in the SECT image by an operation input, the welding work of the designated joining target member is assigned to the worker. Then, by repeating the above work for each worker, a welding work is assigned to a plurality of workers, and the assignment result is printed out as a work instruction for each worker. The details of the procedure for creating the work instruction will be described later.
[0027]
Further, the work management device 3 is configured to update the βNL value of each joining target member according to the progress when the actual value of the welding work is input by operating the keyboard or the like. Each member to be welded is color-coded according to the remaining management amount obtained by subtracting the actual value from the βNL value, and the remaining management of the member to be joined is instructed by an operation instruction with a pointing device or the like. The quantity is configured to be displayed numerically.
[0028]
Next, a time-series operation of the construction work management system configured as described above will be described with reference to the flowchart shown in FIG. This flowchart shows a procedure for creating a work instruction sheet using the work management apparatus 3.
[0029]
In this construction work management system, in the state where only the work block design data is extracted from the design data by the host management apparatus 2, the work management apparatus 3 is operated for various purposes to create work instructions and the progress of work. The situation is confirmed. That is, at the time when the joining work of each block is performed at the work site, the βNL value is calculated by the management amount calculation device 1, the design data generation process based on the βNL value and the three-dimensional shape data, and the work by the upper management device 2 The block design data extraction processing has already been completed as preprocessing. In such a state, the work instruction for each worker is created as follows using the work management device 3.
[0030]
Here, the βNL value can be calculated by using an evaluation function having variables of the welding posture and the shape of the joint part (plate thickness, groove shape, and weld leg length) obtained from the three-dimensional shape data of the work target block. It is automatically calculated by the device 1. That is, in the present embodiment, since the βNL value that has been manually calculated is automatically calculated by the management amount calculation device 1, the time required to calculate the βNL value is shortened and there is very little room for calculation errors.
[0031]
In the work instruction creation process, first, design data (work block design data) is fetched. When the operator inputs a work block design data import instruction, the work management device 3 acquires the work block design data from the host management device 2 via the communication line (step S1). As a result, the work management apparatus 3 displays an image of the three-dimensional shape of the work target block based on the work block design data. When the operator gives an instruction to display the SECT image, the work management apparatus 3 extracts only the joining target member to which the βNL value is assigned as the attribute information and displays it as the SECT image (step S2).
[0032]
The subsequent processing is processing for assigning a specific joining target member as a work target for each worker of each work group. When the operator inputs and inputs the team leader name and the worker name, the work start time and the work end time of the work group (step S3), and further specifies a specific joining target member on the SECT image, the joining target member is It is assigned to the worker corresponding to the worker name (step S4). Here, by repeating the operation designation of the joining target member on the SECT image, a plurality of joining target members can be assigned to the worker corresponding to the worker name.
[0033]
Usually, since the hull welding operation is composed of a plurality of work groups and each work group is composed of a plurality of workers, the judgment in step S5 is “No”, so that the operator can name other workers. The operations of steps S2 and S3 are repeated, and work assignments to workers of work groups corresponding to other worker names are sequentially performed. When the work assignment to all workers is completed as described above and the operator gives an operation instruction for printing, the work management device 3 sends the setting data based on the reasons in steps S2 and S3 to the printer. The work instructions for each worker are printed in color (step S6), and the work instruction creation process ends.
[0034]
According to such a work instruction creation process, the operator can accurately and accurately assign a plurality of members to be joined to each worker, and there is room for occurrence of assignment mistakes or assignment leakage. Extremely less.
[0035]
Further, the work instruction sheet of the present embodiment describes the three-dimensional shape of the work target block, the three-dimensional shape of the joining target member assigned as the work target, and the work schedule on the work day. This work schedule is a graph display of the target value of the work day for the total βNL value of single or plural joining target members assigned as work targets. With the work instruction sheet configured as described above, each worker is accurately instructed on the work location.
[0036]
Subsequently, each worker performs welding work based on the work instruction sheet prepared as described above, and when one day of work is completed, the actual value of welding work related to each joining target member is reported to each group head. To do. The actual value of each member to be joined is input to the work management apparatus 3 using a keyboard or the like. When the actual value is input, the work management device 3 calculates a remaining management amount obtained by subtracting the actual value from the βNL value of each joining target member, and updates the βNL value of each joining target member to the remaining management amount.
[0037]
As a result, each joining target member displayed on the progress confirmation image (three-dimensional image) is color-coded according to the remaining management amount, and when an operation instruction is given to any joining target member using a pointing device or the like, The remaining management amount of the joining target member is displayed numerically. Therefore, it is possible to easily confirm the progress of the welding operation for each joining target member by the SECT image based on the remaining management amount updated in this way.
[0038]
In the progress confirmation image, the progress status of the work day can be confirmed based on the actual value. In other words, each joining target member displayed on the progress confirmation image is color-coded according to the actual value on the day of the work, and the actual value of the joining target member that has been instructed for operation is numerically displayed. By using such a progress confirmation image, a work plan for the next day can be easily drafted.
[0039]
