DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view of a construction blackboard according to the present invention, in which a display board 10 has a black surface and is provided with squares or ruled lines for describing necessary items and a display locked by magnetic force on the surface. It is composed of a sheet 20. On the black surface of the display board 10, ruled lines or cells 25 which are white lines are drawn. However, the size of the ruled lines or cells 25 is not limited at all, and there are no restrictions on the intervals between the ruled lines. Can be set freely according to the purpose of use of the blackboard Further, the description items and the size of the display sheet 20 are completely free, and as described later, it is extremely easy to create the display sheet 20 of any description items according to the usage form. It is.

FIG. 2 is a perspective view of the display board 10,
Generally, it is composed of a front plate 11, a back plate 12, and an intermediate layer plate 13 as a substrate. The surface plate 11 is made of at least a magnetic plate material such as a thin iron plate, and is capable of attracting and supporting a display sheet 20 described later by its magnetic force. Also, the back plate 12 is not necessarily a magnetic material, and may be omitted if the strength of the display board 10 is sufficient. In this embodiment, a thin iron plate similar to the front plate 11 is used. It is configured. The intermediate layer plate 13 as a substrate is formed of a plate made of, for example, a synthetic resin, which is sandwiched and sandwiched between the front plate 11 and the back plate 12. However, the material of the intermediate layer plate 13 as the substrate is not particularly limited.

As is apparent from FIG.
The surface of 1 can be black or dark green. In this embodiment, the surface of the surface plate 11 made of a thin iron plate is coated with black paint. And
Since the surface of the blackboard is finished with ordinary blackboard paint, it can be written with chalk as needed. For example, the sign of an inspector can be written with chalk. In addition, the ruled line or square 25 is drawn using a white line, and constitutes a description item display portion 26 having an arbitrary shape and dimensions. Although the size of the display board 10 is not particularly limited, for example, it can be configured to have a width of 700 × 600 mm, 450 × 600 mm, and the like and a thickness of about 5 to 15 mm, similarly to a conventional construction blackboard. When the reinforcing frame is fixed to the back surface of the display board 10 as necessary, the handling is convenient.

FIG. 3 shows examples (A) to (F) of various display sheets 20, which are one of the characteristic structures of the present invention. That is, each of the display sheets 20 having various sizes or sizes includes a display paper surface 21 and an adhesive substrate 22 which is a substrate to which the display paper 21 is attached. Here, the display space 21
For example, the description on the construction blackboard that is described in the schedule or construction plan displayed on the personal computer etc., such as the construction name, construction date and time, construction location, concrete construction content, etc. 23 and printed out as black and white inverted characters. In this way, as is apparent from FIG. 11, a display paper surface 21 representing various white outlines on a black background can be obtained.

The bonding substrate 22 of the display sheet 20 is formed of a conventionally known magnet sheet. That is, for example, the sheet is a sheet obtained by mixing magnet powder in rubber and solidifying it into a sheet shape, which itself can be adsorbed and fixed to a magnetic material. And this magnet sheet may have a thickness of usually 1 to 2 mm.

The display sheet 20 is formed by bonding the display surface 21 onto such a magnet sheet using, for example, an adhesive, and setting the display surface 21 to a size corresponding to the characters 23 of the display surface 21 or a size suitable for the written contents. The display sheet 20 having a required size is obtained by cutting the sheet together with the adhesive substrate 22 as the magnet sheet using a cutter knife or the like.

FIGS. 4 and 5 show a state in which a work record at an actual work site is created using the present invention.
As shown in FIG. 4, for example, the work contents can be recorded in a photograph together with the work contents in the painting work of the piping portion 05, but any of the described items can be recorded by using the display sheet 20 prepared in advance. Accurate and beautiful records can be created.

Further, even in the record of the painting work 06 in the repair section of the bridge, for example, as shown in FIG. 5, it is possible to accurately and easily record the work place, date and time and work process.
Since the display sheet showing the description items prepared based on the work schedule in advance can be easily recorded simply by attaching it on the display board at the site, the construction contents and the recorded contents can be completely matched. As described above, these display sheets are formed by bonding black and white inverted character display surfaces of recorded matter displayed on a personal computer or the like to a magnet sheet and then cutting out the sheet to an appropriate size.

[0014]

According to the present invention, the construction described above can be used to record the necessary construction status and the like on a blackboard, but all of these items can be printed and recorded by a personal computer or the like. Since it is possible, there is no inconsistency with the contents of the construction plan. In addition, since the process management and the like of the construction can be made as predetermined, the planning of the construction itself is also improved. Since the characters on the display paper can be inverted characters on a personal computer, it is possible to obtain a record of very simple and beautiful white characters, and since such display paper is adhered to a magnet sheet, It has remarkable functions and effects such as being freely detachable on the board and being very easy to handle.
