JPH072645Y2 - Pedestrian pass sheet for construction sites - Google Patents

Description

TECHNICAL FIELD The present invention relates to a pedestrian passage sheet for a construction site that secures walking safety at a construction site.

Conventional technology Conventionally, at work sites such as electrical work, gas work, sewer work, etc., lanes have been clarified by providing fences or markings between the parts that should be pedestrian passages and the construction parts. On the other hand, we tried to ensure walking safety by laying a plywood board etc. on the part that is difficult to walk due to the waste generated by excavation or the surface of the ground caused by peeling of asphalt on the road surface. .

However, if there are complicated detours, etc.,
When the two areas are divided by fences or signs, it is not always possible to clearly indicate which area is the passage for pedestrians, and in some cases this may lead to the illusion of pedestrians. It was dangerous. In addition, when a veneer board is laid on a part that is difficult to walk, the veneer board has a high hygroscopic property and the surface is slippery in rainy weather, which not only poses a risk of falling to pedestrians, but this kind of board material is also heavy. Since it is bulky, it requires a great deal of labor to be transported to the construction site.

Therefore, in order to solve these problems, the inventor of the present invention provides, on one surface of a flexible sheet made of a flexible material such as rubber, a large number of uneven portions orthogonal to the longitudinal direction of the sheet, and Further, a pedestrian sheet for a construction site is provided with a concave portion representing a character or symbol for recognition as a passage for a pedestrian, and the concave portion is provided with a display layer that glows by irradiation of light. It has already been proposed as 55-52088.

This product has a display layer that shines when irradiated with light, and is capable of reliably showing a region that serves as a passage for pedestrians, and has a large number of uneven portions on a sheet material made of rubber, synthetic resin, or the like. This makes the surface less slippery, and by selecting a lightweight and flexible material, it can be wound compactly and can be transported.

In addition, this product has a display layer that shines when irradiated with light and is provided in a recessed portion that is further provided on the uneven surface, so that the display layer does not wear or flake off even on heavy traffic roads, and it can be used for a long time. It bears.

However, when this is used at a construction site where the ground surface is exposed, sand and mud tend to accumulate on the display layer in the recess, and especially in rainy weather, the amount of ambient light decreases and the recess By collecting rainwater, sand and mud are diffused throughout the recess. As a result, the display layer is blocked and the visibility is impaired. Furthermore, this requires a cleaning operation to remove the sand and dirt and dust that have entered the recess, and thus has a problem that the cleaning operation is troublesome. .

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention An object of the present invention is to provide a pedestrian seat for a construction site which is more reliable in terms of visibility and anti-slip function and has good rain finish.

Means for Solving the Problems The present invention provides a sheet made of a flexible material such as rubber or synthetic resin with a large number of concavo-convex portions that are orthogonal to the longitudinal direction of the sheet, and a flat portion on a part thereof. A character portion is provided in a convex shape on the flat portion, a protector having a protrusion amount larger than the protrusion amount of the character portion is provided around the character portion, and a cut groove is formed in a part of the protector and a part of the closed portion of the character part. The above problem was solved by providing the above.

Action A sheet made of a flexible material such as rubber or synthetic resin is laid with the side having the uneven portion facing up, and a large number of the uneven portions which are orthogonal to the longitudinal direction of the sheet act as a slip stopper for walking motion.
On the other hand, the convex character part provided on the flat part has a high light irradiation degree of the display layer, so that the characters are visually recognized by being raised, and these characters are not buried in sand or dust, Since the mud and the like adhered to are wiped off by the friction accompanying the walking motion, the visibility for the pedestrian at night is always secured, and the convex portion also acts as a slip stopper for the walking motion.

The character part prevents the shoulder part of the character part from being directly pressed by a protector with a protrusion amount larger than the protrusion amount of the character part surrounding it, and the water in the protector and the character circuit is discharged from the cut groove to the outside. It

Embodiment An embodiment of the present invention will be described below. In FIG. 1, reference numeral 1 is a long sheet made of a flexible material such as rubber or synthetic resin and having an appropriate width as a width of a passage for pedestrians. A large number of concave and convex portions 2 that are orthogonal to each other are provided (second cross section AA).
See figure).

Further, the flat portions 1a, 1b, 1c, 1d of the sheet 1 are provided with flat portions excluding the convex portions, and the flat portions 1a, 1b, 1c, 1d are provided with "walks", "rows", "persons", respectively. , And "for" are provided in a convex shape, and the surface of each character becomes a character portion 3a, 3b, 3c, 3d provided with a display layer that emits light by irradiation of light. The character portion may be formed of a reflective layer having a large number of transparent spheres such as fine glass or synthetic resin, or a paint layer containing a fluorescent substance. Reference numeral 4 is a protector provided in a convex shape so as to surround each character portion, and the amount of protrusion of the protector 4 is larger than the amount of protrusion of each character portion. This prevents the shoulder portion from being directly pressed and has the effect of making it difficult for the sag to occur on the outer circumference of the character portion. A kerf is provided in a part of the protector 4 to prevent rainwater and the like from collecting on the flat portion, and a kerf is also provided in a part of the closed path of the character to improve rain finish.

In use at a construction site, the sheet 1 is laid along the area that will be a passage for pedestrians with the uneven portion 2 side facing up.

By laying the seat 1 in this manner, the area that serves as a passage for pedestrians is directly displayed on the road surface. Therefore, an illusion that occurs when a fence is provided, that is, "the road surface is divided by the fence However, the illusion that occurs when you set a sign, such as "Which area should you really go through?", "The arrow is displayed on the sign, but the direction of the arrow and the position of the divided road surface" There is no suspicion such as "Which area should we select?" Because they do not exactly match each other, and accidents due to the illusion of a pedestrian are prevented.

In addition, the flat portions 1a, 1b, 1c, 1d are provided on the display portions 3a, 3b, 3 of each sheet 1.
c, 3d, that is, “walk”, “row”, “person”,
Since the letters "for" are provided in a convex shape, the degree of light irradiation of the display layer is higher than that with the display layer in the recessed portion, and the letters are raised and visually recognized, and therefore the visibility is high. Moreover, since these characters are not buried in sand mud or dust, and mud adhered to the surface is wiped off by the friction associated with the walking motion, the display layer shining by the irradiation of light can be applied to pedestrians at night. Visibility is always ensured.
Furthermore, the display portions 3a, 3b, 3c, 3d provided in a convex shape are the uneven portions 2
It also acts as a non-slip, and the cut groove drains rainwater etc. from the flat part inside the protector and the closed part of the character, so it further complements the anti-slip function of the character part itself and prevents pedestrians from falling accidents in rainy weather. It can be prevented.

Further, since the sheet 1 is relatively lightweight and excellent in flexibility, and can be collected by being wound and bundled in the longitudinal direction thereof, each work process of loading and unloading on a transport vehicle, transport, laying, and recovery is very easy. Be converted.

In this embodiment, four display portions 3a, 3b, 3c, 3d are provided, and "walk", "row", "person",
Although the characters “for use” are displayed, it goes without saying that the number of display portions provided on the sheet 1 may be any number, and the characters to be displayed there can be appropriately selected as necessary.

EFFECTS OF THE INVENTION According to the present invention, by providing the convex character portion on the flat portion, the light irradiation degree of the display layer is higher than that having the display layer on the concave portion, and the character is visually recognized as being raised. Therefore, the visibility is high, and these characters are not buried in sand and dirt, and their surface is always in contact with the sole of the shoes to prevent the adhesion of mud. This eliminates the need for cleaning work to remove sand and mud on the letters, and the visibility of the display layer illuminated by light is always secured for pedestrians at night, and it is possible to clearly indicate the existence of a pedestrian passage. As a result, accidents due to the illusion of pedestrians can be prevented. In addition, the convex character part itself has an anti-slip action, and the cut groove drains rainwater etc. from the flat part inside the protector and the closed part of the character, so the anti-slip action of the character part itself is supplemented. However, in rainy weather, it is possible to prevent pedestrians from falling and prevent the shoulders of the character part from being directly pressed by a protector with a protruding amount larger than the protruding amount of the character part surrounding the character part. Since the abrasion of the lever is prevented, it can withstand long-term use.
