Description

  The present invention relates to a pre-cut construction system capable of performing on-site mounting (pasting) after an exterior material (siding board) is previously cut at a processing factory based on on-site measurement data.

The conventional siding board (exterior material) pasting construction is mainly performed by measuring each piece of the board in accordance with the construction part on the site, and cutting and pasting on the site based on the measurement.
In this construction method, a siding board of about 20 kg was measured, cut and pasted on site, and a great deal of labor was required.
In order to alleviate this, a pre-cut method has been proposed in which the siding board is previously cut by a factory machine.
However, the conventional pre-cut construction method is merely cut into an approximate shape from the CAD data for building design, and the conventional labor-to-site measurement, processing and pasting labor are not fundamentally improved.
This is because the CAD data for architectural design and the actual building often have different dimensions.

  In view of the above technical problems, the present invention is a network in which on-site simple measurement and computer-controlled NC cutting machines are linked via a network, processing up to the actual mounting dimensions is performed on the factory side, and can be easily pasted on site. The purpose is to provide a pre-cut construction system for exterior materials using

  The technical gist of the present invention is that in a pre-cut construction system for a building exterior material, the exterior material installation builder computer and the exterior material cutting factory side computer are connected via a network, and the exterior construction material side computer The computer is provided with exterior material attachment schedule display means and measurement data input means for the exterior material attachment schedule, and the cutting processing plant side computer is based on the measurement data input to the exterior material attachment schedule. NC program data creation means for cutting exterior material, storage means for cutting NC program data, means for rearranging cutting NC program data in order of installation on site, transferred NC program for cutting The exterior material is cut based on the data, delivered to the installer, and installed on site.

Here, the exterior material attachment schedule display means provided in the installation construction side computer is provided with a program for registering in advance the basic dimensions of the siding board, the tension surface of the siding board in the house standing plan view, the number of plates, and the tension direction. Based on this basic information registered in advance, the computer on the builder side is prompted to input information necessary for cutting processing such as basic line position, extension specification, slope specification, cutting pattern specification, and measurement value input. The screen can be displayed.
The installer can easily input the dimensions of the building according to the screen.
The exterior material cutting plant computer creates NC program data for cutting each siding board based on the information input by the installer.
That is, the shape and dimensions of the siding board required by the installer are registered in the factory computer using the screen of the installer computer.
Then, the factory computer creates NC program data for processing the siding board into a desired shape and size with an NC cutting machine.
Here, the transfer NC program data for cutting to the cutting machine means that the factory side computer and the NC cutting machine are connected so that the data can be transferred, or the NC program data is loaded into the NC cutting machine by a method such as via a storage medium. This means that the NC program loading method from the factory computer to the NC cutting machine is not particularly limited.
As described above, the NC cutting machine can start precutting of an accurate siding board immediately after measurement by an NC program comprising information measured at a construction site.
The factory-side computer has a function that rearranges the registered siding board processing order into an order that takes into account the loading order at the time of shipment. A loading state is obtained.
This eliminates the need for rearranging the siding boards at the site, improving work efficiency.

In the present invention, as a network construction method between the exterior material attachment builder computer and the exterior material cutting factory side computer, at least if there is a file server that manages the database under the telecommunications means, It is not limited.
From the viewpoint of ensuring security, it is preferable to use a dedicated program for data input / output even if the file server is made public on the Internet.

In the pre-cut construction system using the network according to the present invention, it is possible to accurately measure the building dimensions at the factory by linking the on-site simple measurement and the computer-controlled NC cutting machine without using the conventional architectural design data. A pre-cut that fits can be done neatly.
Thus, the siding board can be installed only by attaching the siding board, and the exterior construction can be performed quickly and with low labor.
Since the cutting process at the construction site can be omitted, the construction period can be shortened, and the cutting process at the factory eliminates noise and dust at the site, minimizing inconvenience to neighboring residents. it can.
Since waste materials are also processed at the factory, the construction site can always be kept clean, making it suitable for construction in densely populated houses.
In addition, since the work is awaited without leaving the material waiting to be processed at the construction site, the place where the material is placed and the place for processing can be greatly reduced.

FIG. 1 shows a construction example of a network according to the present invention.
The siding board precutting method using the network shown in FIG. 1 is a management computer 1 in a management office 1 such as a construction contractor, and a computer on a cutting plant for exterior materials that is a server in a processing factory 3 (hereinafter simply referred to as a factory side). (Referred to as a computer).
The management office has a person in charge of basic data registration and a factory has a person in charge of cutting a siding board.
In addition, on the custom-built home construction site 21, the renovated home construction site 22, the construction site 23 of the house maker, etc., a computer for installing exterior materials for measuring data input (hereinafter simply referred to as a computer on the side of the builder) is arranged. In addition, a person in charge of inputting measurement dimensions and the like is provided.

The installer computer and the factory computer are connected to a network that is an Internet network using an Internet protocol.
Examples of access means to the server include WWW and SQL * Net.

Pre-cutting siding boards for buildings first creates an NC program in the factory computer that takes into account the construction sequence that matches the building shape by linking the computer on the builder side and the computer on the factory side connected via a network. .
Then, precutting is performed by transferring the created NC program to a cutting machine.
When creating the NC program, the processing order is rearranged so that the stacked state is the order in which the siding boards are actually attached.
For example, the person in charge of the management office registers in advance in the exterior material attachment schedule (exterior material attachment details creation program) that has a function for registering basic information on siding board installation according to the construction contents in the factory computer. .
The installer computer has a function of displaying an exterior material attachment schedule provided by the factory computer as a server (exterior material attachment schedule display means and measuring data input means).
Thus, the installer can input the dimensions measured at the construction site and the required cutting shape according to the screen and register them in the factory computer.
Then, after registering data necessary for processing the siding board, NC program data is created in a storage device in the factory computer (cutting NC program data storage means).
The created NC program data is transferred to the NC cutting machine when cutting the siding board. In addition, when transferring the cutting information to the NC cutting machine, a cutting NC program rearranging means is provided so as to be attached in order after unpacking at the site, and a cutting order instruction is incorporated.
The transfer means for transferring NC program data from the storage device of the factory side computer to the NC cutting machine may be transfer using a network or transfer via a storage medium. Not.
The processing person in charge processes the siding board after transferring and loading the NC program data to the NC cutting machine.

FIG. 2 is a block diagram showing the flow of the system according to the present invention.
First, the management person in charge at the management office inputs and registers the property, upholstery, number of plates, and processing pattern from the management office computer to the factory side computer via the network while referring to the residential floor plan ( Step S1).
FIG. 3 and FIG. 4 show screen examples of the builder computer for registering basic information on siding board installation according to the construction contents in the factory computer.
For this screen, the basic dimensions of the siding board, the siding board tension surface, the number of split plates, and the tension direction in the house plan are registered in advance.
Next, the measurement person in charge at the construction site uses the laser level to derive a reference line and make a mark (step 2).
A reference line designation screen shown in FIG. 6 is displayed based on the basic information registered in advance.
From this reference line, the dimensions of each siding board are measured, or the dimensions from the reference line to the edge of the tension surface are measured and input to the construction computer as simple measurements.
This process is shown by the flow from A in FIG.
First, on the screen shown in FIG. 4, the person in charge of measurement inputs initial information such as the construction period, location, type of siding board, etc., then, according to the screen shown in FIGS. 4 and 5, the installation direction and tension (construction) in the building Registers the settings for construction details such as the number of surfaces, the number of vertical divisions, the number of horizontal divisions (required number of sheets), the number of tension parts (the number of uneven parts with respect to the tension surface), the number of tensions, and the tension direction.
In this way, when the setting of the construction content is registered, the factory computer that is the server automatically creates detailed information on the cutting shape and measuring dimensions necessary for specifically cutting the siding board, and this detailed information. The input screen based on is displayed on the construction computer screen.
On this input screen, the person in charge of measurement inputs the presence / absence of processing and the processing shape and dimensions for processing for each siding board.
Then, based on the basic information registered in advance, the factory-side computer sends a reference line designation screen shown in FIG. 6, a stretch / gradient designation screen shown in FIG. 7, and a cutting pattern registration screen shown in FIG. Then, a screen prompting input of specific information necessary for the cutting process such as a reference line measurement input display screen shown in FIG. 9 is displayed.
As a result, the builder can easily input the siding board cutting content that matches the dimensions and shape of the building according to the screen.

The factory computer receives information on the cutting shape, measuring dimensions, and pasting order entered by the installer via the network.
That is, the shape and dimensions of the siding board required by the installer are registered in the factory computer using the screen of the installer computer.
When the input is completed, the NC program data creation process is performed from the NC program creation screen shown in FIG. 10 to create the NC program data in a lump and output it to, for example, the internal storage device of the factory side computer and save it.
This NC program is a program for processing siding boards in the order of construction on site and in consideration of unloading.
When the creation of the NC program is completed, the person in charge of cutting the siding board at the processing plant transfers the NC program data to the NC cutting machine and loads it into the NC cutting machine.
The means for transferring the NC program data to the NC cutting machine is not particularly limited as long as the data can be stored in the NC cutting machine, for example, by copying a file of a factory computer or via an external storage device.
Then, cutting of the siding board is started by the NC program.
In this way, an NC program consisting of information measured at the construction site can be created immediately after measurement.
Since this NC program is based on an accurate measuring dimension, a pre-cut that can be directly attached to a siding board can be performed.
The NC cutting machine pays out the siding boards in the on-site construction order and the order considering the unloading (step S5).
That is, the state in which the siding boards are stacked is the order of attachment in consideration of the tension direction.
This eliminates the need for rearranging the siding boards at the site, thus improving work efficiency.
Then, the person in charge of shipping at the processing factory loads the processed siding boards onto the pallet, and the person in charge of delivery delivers the siding board to the construction site (step S6).
