Description

The present invention relates to a construction blackboard that has been used as a necessity when taking construction photographs that record the progress and processes of construction at various construction sites, etc. For construction work, the display content can be easily changed by obtaining a display of the display surface that can be fixed and replaced with multiple notation boards in order to efficiently operate the construction photography work. blackboard.

With a conventional construction blackboard, supervisors, etc., usually fill in the display contents such as letters and schematics with chalk at the construction site each time a construction photo is taken, and erase the entry and fill in the next display contents. It was intended to be used repeatedly by handwriting and erasing.

In addition, in order to avoid repeated use of entry and deletion at the construction site, it was necessary to prepare multiple construction blackboards with pre-filled display contents according to the photography plan in advance and bring them to the construction site. .

However, in the above display means, the display contents such as characters and schematics become unclear due to dirt on the display surface due to repeated use of entry and deletion, and the work between them is interrupted by taking time to rewrite. In addition, there were inconveniences such as the written characters flowing or not being able to fill in during rainy weather.

In addition, if a plurality of construction blackboards are brought to the construction site, the display contents may be rubbed and disappeared during the transportation, or the transportation may be manual, and there is room for improvement in work in any case.

The present invention solves the above-mentioned problems, can execute a plurality of accurate notations according to the photography plan in advance, and can be replaced with a notation plate for changing the display contents, and is not affected even in rainy weather Provide an all-weather construction blackboard capable of labor-saving and efficient construction photography.

The present invention is a rectangular plastic flat plate processed in the shape of frosted glass or the same type processed in the same way for the material of the notation board on which letters and schematics etc. are actually written with chalk, markers, etc. A rectangular metal plate is used for the outer edge of the blackboard, and plastic, wooden, or metal squares are used on it. A plurality of grooves are provided so as to face each other on the inner side of the peripheral edge, and further, one of the peripheral edges opens and closes. The construction blackboard has a structure in which the fixing positions of a plurality of inserted notation boards can be changed, and the display contents can be easily changed by obtaining the required notation display.

In addition, the sign board is divided into top and bottom or left and right, and it has a partition peripheral part for inserting and fixing each divided sign board. The display content can be changed by replacing only the variable display portion in which the schematic diagram and the dimensions thereof are written.

In addition, the writing instruments for writing on the sign board are familiar with the sign board such as wax system such as Dermatograph (registered trademark) and crayon (registered trademark) and water-resistant marker, and it will be washed away in the rain even in rainy weather. Of course, it can be easily completed even when the notation board is wet, and is provided as a writing instrument for an all-weather construction blackboard.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

1A is a front view and FIG. 1B is a side view of a construction blackboard according to the present invention. In this figure, the construction blackboard of the present invention is for inserting and replacing the three black notation plates 1 and the black peripheral edge 2 provided with three grooves for fixing and fixing the notation plate. 1 includes a handle 4 for holding or hanging the blackboard, and a leg 5 for raising the blackboard. FIG. 1 shows a state in which the open / close portion is closed, and FIG. 2 shows that the open / close portion is opened. It is the (c) front view and (d) side view of a state.

A black acrylic board is used for the material of the notation board 1, and both the front and back sides are finely concavo-convex in the shape of ground glass, and the construction name, white character of the work type, and the white frame line 6 are printed. Yes.

Recycled polystyrene resin squares are used for the peripheral portion 2, and stainless steel pulling handles are used for the handle 4.

The notation board is filled with the construction status, schematic diagram or completed drawing based on the photography plan and their dimensions, etc. The construction blackboard of the embodiment of the present invention has three notation boards and six faces. , You can fill in six types of construction status in advance, or you can paste letters and schematics printed using a personal computer in advance on the notation board, by changing the notation surface according to the shooting target The display necessary for continuous construction photography can be obtained immediately.

For writing instruments, if you use a water-based marker, etc. rather than chalk, it will also prevent stains on the notation board, and wax-based writing instruments such as Dermatograph (registered trademark) and crayon (registered trademark) are suitable for rainy weather measures, Oil-based pens such as water-resistant markers can also be used, and they can be used in fine weather without any problems.

As for the eraser, melamine foam is used, but a commercially available felt eraser soaked with fats and oils can be substituted.

As for FIG. 3, the notation plate 1 of FIGS. Three signboards are inserted, and multiple construction sites with different construction names can be photographed with a set of construction blackboards.

Effect of device

The present invention can be used when taking a construction photograph in advance by filling out the required number of completed forms and schematics according to the construction status and progress status and their dimensions on the sign board. In addition, a continuous construction photograph can be taken immediately by simply replacing and displaying a necessary notation board on the display surface, which can contribute to labor-saving and efficient operation of construction photography and related work.

It is the surface view (a) and side view (b) of the blackboard for construction photographs which is the Example of this invention. It is the surface view (c) and the side view (d) which opened the opening-and-closing part of the construction blackboard of FIG. 1, and has inserted three notation boards. It is the surface view (e) and side view (f) of the construction blackboard which divided | segmented the construction blackboard of FIG.
