Description

Scaffold modeling method and computer program {METHOD AND COMPUTER PROGRAM FOR MODELING SCAFFOLDING}

The present invention relates to modeling of scaffolds, and more particularly, to modeling of scaffolds installed by a pipe method.

In general, scaffolding is a temporary structure installed so that construction can be carried out at a high place. Scaffolds are also called asshiba, chieftains, and scaffolds.

Scaffolding is often installed at a construction site in the form of enclosing a building under construction. At construction sites, scaffolding is usually used for remodeling and repairing exterior walls, applying cement, or painting paints. Scaffolding can also be seen in shipbuilding sites in shipyards. In this case, scaffolding is used to paint the inside and outside of the ship or to install wires and machines.

Scaffolding methods include a piece method and a pipe method. Which one of these construction methods to choose depends on the type of building or ship under construction.

In order to model the scaffold installed by the conventional pipe method, the designer had to manually arrange all the materials of various sizes and various quantities constituting the scaffold according to the rules to construct the scaffold having the desired structural dimensions.

However, such work has a problem that it is very complicated, difficult, and cumbersome. Therefore, there is a problem that errors generated due to the designer's mistake may exist in the result calculated by such work. Furthermore, there is also a problem in that it is difficult for the designer to grasp the existence of an error caused by his/her own mistake in the result.

In addition, there is a problem of increasing the number of design hours because such work requires a very large amount of time.

In addition, even if such work is performed, in order to grasp the quantity of materials required for the scaffolding to be installed, the designer calculates the quantity of each of various materials having various sizes (eg, various pipes having various lengths) from the calculated result. There was a problem that I had to figure it out on my own.

An object to be solved by the present invention is to provide a method and a computer program for easily, accurately and quickly modeling scaffolds to be installed by a pipe method, and to easily grasp the quantity of materials required for scaffolding to be installed.

Preferably, the structural dimensions include a bay width, a number of bay widths, a bay length, a number of bay lengths, a lift length and a number of lift lengths, wherein the pipes are made of a ledger, a transformer Includes Transom and Standard.

Preferably, the scaffold modeling method comprises the steps of: receiving an input on a screen location to place the modeled scaffold; and arranging the modeled scaffold at the received position on the screen.

Preferably, the scaffold modeling method comprises: receiving an input of a size and an arrangement position of a scaffold component to be additionally disposed on the modeled scaffold; and further disposing the scaffolding component having the received size at the received placement location.

A computer program according to an embodiment of the present invention for solving the above problems is stored in a medium in order to be combined with a computer to execute each step of the scaffold modeling method.

According to the present invention, it is possible to easily, accurately and quickly model the scaffold installed by the pipe method. Therefore, it is not necessary for the designer to directly perform complicated, difficult and troublesome work, errors due to the designer's mistake can be prevented, and the design time can be reduced. In addition, it is possible to easily grasp the quantity of materials required for the scaffolding to be installed.

1 is a flowchart of a scaffold modeling method according to an embodiment of the present invention. Referring to FIG. 1 , a scaffold modeling method 100 is a method of modeling a scaffold installed by a pipe method. The scaffold modeling method 100 may be performed by a computer having a processor and a memory.

In order to model the scaffold installed by the pipe method, first, the computer outputs an input window into which information can be input. The computer receives the structural dimensions of the scaffold to be modeled from the user through the input window (S110).

The structural dimensions of the scaffold are the dimensions of the elements constituting the scaffold structure. The structural dimensions of the scaffold include a bay width, a number of bay widths, a bay length, a number of bay lengths, a lift length, and a number of lift lengths.

For example, if the bay width is 2,500 mm and the bay length is 2,500 mm, then a 2,500 mm wide and 2,500 mm long square is a unit bay, and if the number of bay widths is 4 and the number of bay lengths is 4, the unit bays are per floor. Four unit bays are arranged in the width direction and four units are arranged in the longitudinal direction, so that a total of 16 unit bays (=4 rows x 4 columns) are arranged on each floor. And, if the lift length is 2,500 mm, the height between the layers becomes 2,500 mm, and if the number of lifts is 4, 4 layers are added in the height direction to the first floor, which is the floor layer.

The computer receives the length of the pipes constituting the scaffold from the user through the input window (S120). The pipes that make up the scaffolding include Ledger, Transom and Standard. The leather is a pipe arranged in the width direction of the scaffold, the transom is a pipe arranged in the longitudinal direction of the scaffold, and the standard is a pipe arranged in the height direction of the scaffold.

The input window may provide a drop-down list of selectable pipe lengths for each of Reza, Transom and Standard. The user can enter the pipe length by selecting the desired pipe length from the drop-down list. The pipe lengths constituting the drop-down list are actually available pipe lengths or pipe lengths selected according to other criteria, which are stored in the computer in advance.

In addition, the input window allows the user to separately select and input the length of the pipe used for the first time, the length of the pipe used in the middle, and the length of the pipe used at the end for each of the leather, transom, and standard.

So, the user selects the same or different length of the pipe used for the first time, the length of the pipe used in the middle, and the length of the pipe used at the end for each of Reza, Transom, and Standard through the input window. can do.

For example, the user selects and inputs 6,000mm as the length of the pipe used for the first time for leather, selects and inputs 4,000mm as the length of the pipes used in the middle, and sets the length of the pipe used last. can be entered by selecting 4,500mm.

The computer receives the modeling command after receiving the structural dimensions of the scaffold and the length of the pipes through the input window from the user. The modeling command is a command to 3D model the scaffold with the input structural dimensions of the scaffold and the length of pipes. The modeling command may be input from the user through the input window.

The computer receiving the modeling command three-dimensionally models and outputs the scaffold configured to have the received structural dimensions with pipes of the received length (S130). In addition, the computer classifies the pipes used in the modeled scaffolding by type and length, and calculates and outputs the number of pipes corresponding to each classification. Such modeling and counting are automatically performed in a computer by an algorithm that is pre-programmed and stored in the computer.

In this way, there is no need for a user to construct a scaffold having a desired structural dimension by directly arranging all pipes of various sizes and various quantities in order to model the scaffold. The user can model the scaffold easily, accurately and quickly by inputting only the structural dimensions of the scaffold and the length of the pipes. In addition, the user can easily grasp the quantity of pipes required to construct the scaffold of the desired structural dimensions by inputting only the structural dimensions of the scaffold and the length of the pipes.

Meanwhile, the computer may receive a reference point of a position on the screen where the modeled scaffold is to be placed from the user through the input window. The computer arranges and outputs the modeled scaffold based on the reference point of the position on the screen input from the user.

The user can select and input the reference point of the location on the screen where the modeled scaffold is to be placed on the screen on which the ship or structure is placed, and in this case, the user considers the location on the screen of the ship or structure and the screen where the modeled scaffold is placed. The reference point of the image position can be selected. When the modeled scaffolding is arranged based on the reference point of the selected location on the screen, the user can check in advance the state in which the scaffolding is installed on the ship or structure.

When the user determines that the modeled scaffold needs to be modified, the scaffold can be remodeled by re-entering the structural dimensions of the scaffold and/or the length of pipes. Users can repeat the remodeling until satisfactory results are obtained.

The computer may receive a clamp check command from the user through the input window. Clamps are fastened wherever the pipes cross, and serve to hold the crossed pipes firmly so that they are fixed. The clamp check command is a command to calculate the number of clamps required for the modeled scaffold.

The computer receiving the clamp check command calculates and outputs the number of clamps required for the modeled scaffold. This counting is also performed automatically in the computer by an algorithm that is pre-programmed and stored in the computer.

The user may further place ancillary scaffolding components on the modeled scaffold. If there is such an additional arrangement (S140), the computer receives the size and arrangement position of the scaffolding component to be additionally placed on the modeled scaffold from the user through the input window (S150).

Additional scaffolding components that may be further disposed on the modeled scaffold include Bracing, Board, Handrail, Kick Board, and Ladder.

Bracing refers to reinforcement applied diagonally to the quadrilateral to prevent deformation of the pipe frame woven in quadrilateral. Board refers to a footing used as a path and work space for workers. A handrail is a safety railing. A kickboard is a toe plate that prevents an operator's toe from protruding to the outside. A ladder is a device that can be stepped on when going up and down a high or low floor.

The computer additionally arranges and outputs the scaffolding component having the input size at the input placement position (S160). In addition, the computer calculates and outputs the number of additionally disposed scaffolding components. These additional batches and counting are also performed automatically in the computer by algorithms that are pre-programmed and stored in the computer.

The above steps (S150, S160) of receiving the size and arrangement position of the scaffolding component and further disposing on the modeled scaffold may be repeated until all scaffolding components to be additionally disposed are disposed (S170).
