[Conventional technology]

Traditionally, overpasses have been made accessible not only by people but also by wheelchairs, bicycles, and motorbikes by making the entire road surface of the access road for overpasses flat, or by making only part of the road surface flat and the other part made into stairs. There is something I did.
In this case, the above-mentioned road surface is constructed flat with concrete, but constructing the road surface of the ascending/descending passageway with concrete requires large-scale construction machinery and a long construction period. Construction work such as remodeling a part or the front part of a road to make it a flat road surface is not carried out unless it is extremely necessary.

[Problem that the invention attempts to solve]

However, even though there are many cases where it is convenient to make a part of the staircase a flat surface even if there is not a lot of traffic, there are cases where there is not enough demand to remodel it with concrete. In such cases, there was a problem in that the device had to be left as is without modification.

The purpose of this invention is to solve the above problems, and to provide an inexpensive, easy-to-use road that can be easily constructed in a short period of time without using large-scale construction machinery, unlike when constructing a concrete road surface. do.

[Means for solving problems]

The means taken to achieve the above purpose is that the engaging piece of the resin molded block is formed by integrally providing an engaging piece on one end of a flat tread reinforced with ribs, and the above-mentioned engaging piece is attached to a step on a staircase, etc. The other end of the tread is supported by the outer edge of the tread on the lower side of the stepped part, and the space between the tread and the resin molded block is fixed. is blocked by the outer panel.

[Example] Fig. 1a is a bottom view of a resin molded block A used for a simple passageway according to an embodiment of the present invention, and Fig. 1b
The figure is a sectional view taken along line A--A in FIG. 1a. This resin molded block A has an inclined engagement piece 2 integrally provided at one end of a flat footboard 1, and a plurality of stripes (four stripes in the illustrated example) extending in the longitudinal direction of the footplate 1 and the engagement piece 2. ) is reinforced by ribs 3..., and is formed by protrusions 4, 4 provided at both ends of the footboard 1 in the width direction and ribs 3, 3 corresponding to these protrusions 4, 4. It has groove parts 5, 5. Note that a portion (hereinafter referred to as an engaging portion) 3a of the ribs 3 provided on the plurality of engagement pieces 2 constitutes a part of the engagement piece 2.
In addition, the other end 1a of the footboard 1 protrudes from the ends of the ribs 3... and the protrusions 4, 4 by a certain width h, and the ribs 3... and the protrusions 4, 4 protrude from the ends of the footboard 1.
A portion provided at the other end 1a is obliquely cut away. The surface of the footboard 1 is treated to prevent slipping by making it an uneven surface, forming a plurality of grooves, or by other means.

FIG. 1c shows an example of a simple passage constructed using the resin molded block A described above. As shown in the illustrated example, the resin molded block A locks the engaging portions 3a of the ribs 3 constituting a part of the engaging piece 2 to the tread surface 11 on the upper step side of the stairs, and the tread plate 1
By supporting the other end 1a on the outer edge of the lower step side tread 11, the tread 1 is leaning diagonally against the stepped portion of the stairs. In addition, on the adjacent step of the stairs, the engaging portions 3a of the ribs 3 of the resin molded block A installed on the lower step side are connected to the end portions 1a of the tread plate 1 of the resin molded block A installed on the upper step side.
are matched against. Furthermore, the oblique side of a substantially triangular outer plate 20 is fitted into each of the grooves 5, 5 (see Figs. 1a and 1b) of each resin molded block A, and the outer plate 20 is used to form a stairway. The space between the surface 11 and the resin molded block A is closed.

In the easy passageway shown in Fig. 1c, a nearly flat road surface suitable for bicycles, wheelchairs, and motorbikes is formed by the treads 1 of resin molded blocks A installed at each step of the stairs. The uphill slope of the stairs is equivalent to the uphill slope of the stairs. Further, the outer panel 20 prevents dirt from accumulating under the road surface, resulting in a clean appearance.

When constructing a passageway using resin molded blocks A as shown in FIG. 1c, by supporting the other end 1a of the footboard 1 on the tread surface 11 as shown in FIG. It is desirable that the piece 4 be raised above the tread surface 11 or be in a state in which it is in light contact with the tread surface 11. By doing this, the end portions 4a, 4a of the projecting pieces 4, 4 are supported by the tread surface 11, and the other end portion 1a of the tread plate 1 does not rise from the tread surface 11. Even if the resin-molded block A runs over the block A, the resin molded block A will not flutter, and the noise associated with the flutter will not be generated. Step board 1 as described above
The state in which the other end portion 1a is supported by the tread surface 11 is as follows.
The other end 1a of the footboard 1 protrudes from the ribs 3... and the protrusions 4, 4 by a certain width h, and the ends of the ribs 3... and the protrusions 4, 4 are obliquely cut out.
Even if there is a difference in the steps of the stairs, it will be secured if the difference is not too large. The support state shown in FIG. 2 is similarly ensured even when the depth widths of the treads are different, since the other end 1a of the tread plate 1 is supported by the tread surface 11 if the difference is not very large.

In the above embodiment, the heights of the ribs 3 and the protrusions 4 are different, but the height of the ribs 3 into which the outer plate 20 is fitted is made as high as the protrusions 4 to ensure a secure fit. May be secured. Further, the height of all the ribs 3 may be made the same as the height of the protruding piece 4.

In the embodiment described above, there is a concern that the footboard 1, which is placed against the step of the stairs, may shake or shift when a bicycle or the like passes by. 3a...
and the tread surface 11, and the other end 1a of the tread plate 1 and the tread surface 1
This problem can be solved by joining 1 with adhesive. However, the engaging portion 3a of the rib 3, which is a part of the engaging piece 2, and the other end 1a of the footboard 1 are bonded with adhesive.
is attached to the tread surface 11, when replacing a part of the resin molded block A that is missing or damaged,
It takes time and effort to peel off the engaging portions 3a... and the other end 1a of the footboard 1 from the tread surface 11, remove the adhesive remaining after peeling them off, and apply new adhesive. There are such difficulties.

Therefore, a simple passageway that does not have such difficulties and a resin molded block A that can construct such a simple passageway will be described next.

The resin molded block A shown in FIGS. 3a and 3b has a locking piece 5 integrated between two ribs 3, 3 at the center in the width direction in the vicinity of the other end 1a of the footboard 1. It was established in In this resin molded block A, the locking piece 5 is the third
It is engaged with a locking member 30 bonded to the outer edge of the stair tread 11 with adhesive as shown in FIG. According to this, displacement of the footboard 1 is prevented by the locking member 30.

The resin molded block A shown in FIG. 4a has an inwardly folded locking part 6 integrally provided at the tip of the engaging piece 2.
Locking member 3 bonded to stair tread 11 with adhesive
The above-mentioned locking portion 6 is fitted into and locked into the recess 31a. According to this, the locking portion 6
The engagement between the locking member 31 and the locking member 31 prevents the engaging piece 2 from lifting up and the footboard 1 from shifting its position.

The resin molded block A shown in FIG. 4b has locking pieces 8a and 8b integrally provided at two locations on the engaging piece 2. In this resin molded block A, either one of the locking pieces 8a, 8b is engaged with a locking member 32 bonded to the stair tread 11 with adhesive. According to this resin molded block A, not only is the displacement of the footboard 1 prevented by the locking member 32, but also when the depth width of the footboard 11 is long, the locking piece 8b on the tip side is moved by the locking member 32. On the other hand, when the depth width of the tread surface 11 is short, the other locking pieces 8b can be engaged with the locking member 32. There are advantages that can be used in common.

The resin molded block A shown in FIG. 4c has a structure in which a protrusion 9 is provided on the engaging portion 3a of the rib 3 that constitutes a part of the engaging piece 2. In this resin molded block A, the projection 9 is fitted into a recess 33 formed in the tread 11 of the stairs. According to this, the engagement between the recess 33 and the protrusion 9 prevents the footboard 1 from shifting.

The configuration of FIGS. 3a and 3b described above, and the configuration of FIG. 4
It is possible to combine any of the configurations shown in FIGS. a to 4c, and by doing so, displacement of the footboard 1 can be more reliably prevented. In addition, if some of the resin molded blocks A are missing or damaged, remove only the resin molded blocks A from the stairs and replace them with new resin molded blocks without peeling off the adhesive joints. This is advantageous in terms of maintenance.

In addition, in FIGS. 3a, 3b, and 4a to 4c, the same parts as those in FIGS. 1a to 1c and FIG.

FIG. 5a shows a resin molded block A used for an easy passageway according to another embodiment of the present invention. This resin molded block A has an engaging piece 2 integrally provided at one end of the footboard 1, a seating piece 10 integrally provided at the other end of the footboard 1, and a width of the footboard 1. Grooves 5, 5 are provided at both ends in the direction. The seating piece 10 is the footboard 2
It is slightly tilted towards the ground. Such a resin molded block A has the seating piece 10 supported on the outer edge of the tread 11 as shown in FIG. By locking the footboard 1 at the top, the footboard 1 is leaning diagonally against the stepped portion of the stairs. Note that the engaging piece 2 and the seating piece 10, and the seating piece 4 and the tread surface 11, which are superimposed on each other, may be joined with adhesive, but the locking portion or the latching piece may be attached to the tread plate 1 as in the above embodiment. They may be provided integrally and joined to the tread surface 11 or engaged with a locking member.

Since the resin molded block A shown in FIG. 5a has a bulging protrusion 12 on the back surface of the tip end of the engagement piece 2,
When the engagement piece 2 is engaged with the stair tread 11 (directly or via the seating piece 10)
As shown in FIG. 6, this protrusion 12 is supported by the tread surface 11. In the figure, the solid line indicates the case where the step difference in the stairs is small, and the imaginary line indicates the case where the step difference in the stairs is large.As is clear from these, even if there is a difference in the step difference in the stairs, the difference is not very large. Since the protrusion 12 is supported by the tread surface 11, the engagement piece 2 does not lift off from the tread surface 11. Even if the depth width of the tread surface 11 is different, if the difference is not very large, the above-mentioned protrusion 1
2 is supported by the tread surface 11, the engagement piece 2 will not be lifted up from the tread surface 11. On the other hand, the engaging piece 2 may be formed into a flat plate shape, for example, as in the resin molded block A shown in FIG. When the tread 11 is locked, the tread 1 shown by the imaginary line in the figure may change depending on the step of the stairs and the depth width of the tread 11.
It is also possible that the outer edge of the engagement piece 1 hits the middle part of the engagement piece 2 and the tip of the engagement piece 2 is received up from the tread surface 11. Therefore, while the resin molded block A shown in Fig. 7 can be used when creating a passageway for stairs where the depth width of steps and treads are the same or similar,
The resin molded block A shown in FIG. 5a can be used to construct a passageway for stairs even if the steps or the depth widths of the treads are different, as long as the differences are not too large.

In the above-mentioned easy passageway, resin molded block A has excellent surface gloss due to the characteristics of the resin itself, and it is possible to apply various patterns and colors during the molding process, so such patterns are applied. and exhibits an excellent decorative effect. In addition, it is easy to make resin molded block A fluorescent by appropriate means such as applying fluorescent paint, and by doing so, the location of the easy passageway can be clearly identified even when it is dark, such as at night. Easy to recognize and convenient for users. Resin molding block A can be molded from hard synthetic resin as a raw material resin, but especially when molded from hard polypropylene resin mixed with reinforcing fibers such as glass fiber,
It is highly durable with excellent wear resistance and water resistance, making it ideal as a welfare member for easy access routes.

In the above embodiment, the tread 1 of the resin molded block A was placed against the step part of the stairs.
The easy passageway of this invention has resin molded blocks A on the step part formed at the boundary between the road surface and the sidewalk.
Forming such a simple passageway is convenient because it allows bicycles to be smoothly taken in and out of a garage or the like provided on the opposite side of the road across the sidewalk.
