The present invention relates to a method for measuring hole / plate spacing, and more particularly, to a method capable of conveniently and precisely measuring the distance between centers of a longage and the distance between centers of slits, and storing / displaying measured data in real time. It is about.

Frequently, the ship's construction adopts block construction. A block refers to a unit made by dividing the hull. In this case, if the subassembly of the block is separated and pre-assembled is applied, the effect can be further enhanced. Among these block drying methods, there is a slit method, which is a method for reducing the shortcomings of the conventional slot method, and the slit formed on the panel and the slit formed on the floor are combined. Thereby forming a single conjugate.

Figure 1 shows the combined structure of the panel and the floor constituting the hull of the ship as a representative object for applying the measuring method of the present invention. The panel 11 is formed by arranging a plurality of longages 12 in one direction, and the floor 13 is formed with a slit 14 to be coupled to correspond to the gap of the longages 12.

Here, when welding the long paper 12 on the panel 11, or when forming the slit 14 on the floor 13, for measuring the distance between the long paper 12, the slit 14 A non-coupling section occurs due to an error of a measuring device, a mistake of an operator, shrinkage deformation due to welding heat when welding the longage 12, and the like.

The non-combinable section refers to a phenomenon in which the rouge 12 is biased toward one side of the slit 14 due to a gap error between the rouge 12 and the slit 14. In this case, one side of the slit 14 is cut. By doing so, the re-cutting process is performed so that the longage 12 and the slit 14 can be combined. The re-cutting process takes a lot of additional time, and there is a problem of economic deterioration due to the amount of re-cutting.

Therefore, it is natural that minimizing the above-described re-cutting process contributes to the improvement of workability and productivity. For this purpose, it is necessary to measure and precisely measure the spacing between the longages and the spacing between the slits. It is necessary to be able to predict the interval in advance and respond quickly to it.

At present, the longage and slit intervals are measured with a tape measure. The measured values are not stored and managed as data, and the measured values are written with oil pens on the side of the longside or floor. However, this method is problematic in terms of measurement accuracy, work efficiency and speed.

Recently, the tape measure is used instead of the existing tape measure, and the digital caliper has been spotlighted as the measuring device. However, the above problem still remains in that the imbalance and measurement data of the working process using the measuring equipment are still recorded manually.

The present invention is to solve the above problems, the object of the present invention is to provide a measuring method that can measure the distance between the center of the long and the center of the slit conveniently and precisely to minimize the slit re-cutting process. .

Another object of the present invention is to provide a method for storing and displaying measured data in real time, so as to predict a section in which a slit should be recut in advance and to respond quickly to it.

In order to achieve the above object, the hole / plate spacing measuring method according to the present invention comprises: a measuring member information input step (S100) of inputting information of a member to be measured; A measurement data input step (S200) through which data measured through a hole / plate spacing measuring device is input; A welding line presence input step S300 in which whether the welding line exists between the long paper and the long paper, or between the slit and the slit; And a data processing step (S400) of storing and displaying the input measurement member information, the measurement data, and a result regarding the presence or absence of the weld line.
