Description

[Detailed explanation of the invention] <Industrial application field> This invention utilizes curing sheets (including mesh-shaped ones) surrounding construction sites to
It relates to a device for promoting and advertising.

<Conventional technology> Traditionally, when constructing houses and buildings, or constructing elevated structures such as railways and bridges, it has been used to prevent accidents caused by falling objects or for aesthetic purposes.
It is common practice to surround buildings with fabric sheets, that is, curing sheets.

<Problem that the invention aims to solve> These curing sheets have the name of the builder on them, or have plates attached to them to alert people passing by the construction site about the construction work. However, although these all function well during the day, they are of no use after sunset, as they cannot be distinguished due to darkness. In addition, if construction is being done in a place where many people can see it at night, if this curing sheet surface can be used to convey information to many people, it will be of no use other than preventing falling objects at night. This means that the unused curing sheet surface can be used effectively even at night.

<Means for Solving the Problems> The present invention provides a group of curing sheets surrounding a construction site, at least one of which is translucent, and a group of curing sheets surrounding the construction site. This is an information night transmitting device comprising a lighting device that can illuminate the translucent sheet portion from inside and form characters or patterns on the illuminated portion. Alternatively, it can attract the attention of people passing by a construction site even in a dark place such as underground, and can be used for advertising.

The curing sheet used in this invention is one that is used at ordinary construction sites, etc.
It is specified in JISA8952-1977.
For example, the tensile strength (weakest direction of length and breadth) is 50Kgf or more, and the eyelet strength (weakest direction of length and breadth) is 0.25Kgf or more (L is the distance between eyelets (mm)). There are various sizes within the range of (1800 to 5400) mm x (3600 to 6800) mm, and the size is selected from this range depending on the purpose.
It is said to be large enough to be pieced together to surround the construction site.

A light-transmitting curing sheet must be used for at least a part of the enclosure made of these curing sheets. The curing sheets used at ordinary construction sites do not have the necessary translucency.
The light-transmitting curing sheet used in this invention is
When light is applied to one side of the sheet, the light can pass through the sheet sufficiently.For example, a curing sheet that is commonly used is impregnated with resin to make it transparent, or a sheet that is made transparent. like,
Examples include those with different fibers and weaving methods. A pattern or text may be drawn on the light-transmitting portion of the curing sheet so that the pattern or text appears when exposed to light. In addition, in translucent curing sheets, by using threads that have a different light transmittance than other parts in the parts that will become patterns or characters, the sheet will be able to A similar effect can be obtained by changing the fabric weight and weaving method.

However, simply shining a light on the letters and patterns formed on a translucent curing sheet to reveal the letters and patterns does not change the letters or patterns midway through, and attracts people's attention. The drawback is that it is difficult to collect over a long period of time. In order to improve this point, it is preferable to change the color and intensity of the light or give it movement over time in the lighting that is applied from behind the curing sheet.

A more preferable method is to use the light-transmitting part of the curing sheet as a screen and use a projector or slide device installed inside the curing sheet to project the screen to attract the attention of people outside for a long time.

Next, the present invention will be explained based on the drawings. 1st
The figure is a perspective view of a construction site using the device of the present invention, and FIG. 2 is a plan view thereof. In the figure, 1 is a building, 2 is a curing sheet, 3 is a screen projected on the surface of the curing sheet (this part is made of a transparent curing sheet), and 4 is a light source for projection.
As is clear from these figures, the present invention uses a translucent curing sheet for at least a part of the curing sheet surrounding the building, uses this part like a screen, and uses the area surrounded by the curing sheet (the building object side)
Light is shined on the translucent part of the curing sheet, thereby revealing letters and patterns on the surface of the curing sheet, thereby transmitting information to people outside the area surrounded by the curing sheet. .

<Effects of the invention> With this invention, it is now possible to attract the attention of many people and convey information at construction sites using curing sheets, which previously only served to prevent accidents caused by falling objects at night. It became possible.

The present invention will be explained below with reference to Examples.

Example: Young bamboo and milky white soft vinyl chloride resin were laminated to a base fabric in which 13 filaments of 2000 dr polyester filament were implanted per inch in the weft direction, and the light transmittance at a wavelength of 500 nm was 1% and 50
A sheet corresponding to Class 1 of JIS A8952 was produced.

This sheet was sewn into a sheet with dimensions of 1800 x 4500 mm and a peripheral eyelet interval of 250 mm, and a Wakatake color sheet.
Using 10 sheets and 2 milky white sheets, we lined up 4 sheets horizontally and 3 vertically using the same grommet rope as before on a steel frame at the construction site, making a total of 12 sheets, with the milky white sheet in the center. It was installed so that it was located in the section.

Separately, cut letters made from a black vinyl sheet with almost no light transmittance were attached to a milky white sheet using adhesive, and the milky white sheet installed at the above site was set as a focal point, and the surface brightness of this sheet was The product of the present invention was manufactured by setting two lighting devices, one each on the upper and lower parts of the mounting sheet, so that the light intensity was 100 candela/m ² .

During the day, this sheet is almost the same as the conventional product, but at night, despite the dim surroundings, the milky white sheet shines and the letters stand out, demonstrating extremely good information transmission. In addition, the lighting devices set on the top and bottom are blinked at regular intervals, so that both the top and bottom lights are on, and only the top one is on.
It was also found that repeating no lighting and changing the intensity of the light was also effective in transmitting information.
