BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an outer frame of a curb block according to the present invention. (Embodiment 1) FIG. 1 is a perspective view of an embodiment (hereinafter referred to as "embodiment 1") of an outer frame of a curb block according to the present invention, and FIG. 2 is a plan view thereof. As shown in FIGS.
The first embodiment is an outer frame composed of an upright portion and a horizontal portion, and is composed of two L-shaped side portions 10, a front portion 20 of an upright portion, a back portion 30, and a front portion 40 of a horizontal portion. Yes,
The upper part of the upright part, the upper part and the bottom part of the horizontal part are openings. As shown in FIG. 2, ten semicircular fixing plates 50 are provided at the bottom, and each fixing plate 50 is provided with a fixing nail hole 51.

A plurality of detachable width stoppers 60 and 70 are provided on the upright portion and the horizontal portion of the outer frame, respectively. This width stopper is for preventing the outer frame from expanding when the outer frame is filled with concrete.
As shown in FIG. That is, the width stoppers 60 and 70 have hook holes 61 and 71 at both ends as shown in FIG. 3, and the hook holes 61 and 71 match the receiving shafts 62 and 72 provided on the outer frame body. Shafts 62, 72 which receive width stops 60, 70 from
It is designed to be inserted and attached to. Although the width stopper is detachable in the first embodiment, it may be formed integrally with the outer frame. Further, the thickness of the outer frame may be increased, or a stiffener may be provided inside the outer frame to eliminate the width stop.

As shown in FIGS. 1 and 2, a projection 11 is provided on one side of a side surface 10 and three recesses 12 are provided on the other side thereof so as to fit into the projection. A large number of outer frames can be connected by inserting the projections 11 into the recesses 12 of the adjacent outer frame side surface portion 10 from above. The outer frame thus connected is shown in a perspective view in FIG. 4, and the connected state of the outer frame is shown in an enlarged plan view in FIG. As shown in FIGS. 4 and 5, the outer frames at both ends do not have protrusions on one side surface serving as an end, and the height of the horizontal portion of the side surface coincides with the road surface. The height of the other side portion is higher than the height of the other side portion, and the upper portion of the side portion also reaches the uppermost step, and these points are different from the outer frame of the middle portion (the outer frame shown in FIG. 1). For example, the length from one side of the outer frame to the other side is 1 meter, and 10 of them are connected to form a series of 10 meters outer frames. In the series of frames connected in this way,
As shown in FIG. 4, the upper end of the side portion of the upright portion is lowered from the uppermost portion except for both end portions, and the upper end of the side portion of the horizontal portion is also lower than the height of the side portions of both ends.

Also, as shown in FIGS. 1 and 4, one of the upper portions of the front portion 20 of the middle outer frame projects slightly laterally, and there is a portion where the thickness of the portion is reduced. There are places where the surface has receded so that the protruding part can be accommodated. The same applies to the front surface portion 40 of the horizontal portion, and when the outer frames are connected to each other, one comes to the other front surface and comes into close contact with the other frame (see FIG. 5). This is to prevent the concrete from leaking from the boundary between the side surface of the outer frame and the side surface of the adjacent outer frame when the concrete is filled. Next, a method of actually installing the curb block on the sidewalk side end of the road using such an outer frame will be described.

FIGS. 1 and 2 show a state in which the width stoppers 60 and 70 are attached. First, all the width stoppers 60 and 70 are removed. Next, a combination of a plurality of L-shaped vertical reinforcing bars and a plurality of horizontal reinforcing bars orthogonal to the L-shaped reinforcing bars is placed on the ground, and the outer frame is covered from above. Next, a nail is driven into a nail hole 51 provided in the fixing plate 50 at the bottom to fix the outer frame to the ground. Next, the reinforcing bar is set inside the outer frame so as to be at a predetermined position, and the width stoppers 60 and 70 are attached to the outer frame. At this time, the width stop 60 comes under the uppermost horizontal reinforcing bar. Next, the adjacent outer frames are connected to each other by the protrusions 11 and
Are fitted and connected, and the outer frames each containing a reinforcing bar are nailed to the ground, and the width stoppers 60 and 70 are attached to the outer frame body. Thereafter, the concrete is poured from the opening in the upper portion of the outer frame and the opening in the horizontal portion, and the concrete is sufficiently spread inside the outer frame. As already mentioned, the side part height of the horizontal part is the same height as the road surface at both ends,
Since the middle part is lower than that, the concrete is filled up to the upper part of the middle side part, and the concrete surface is formed with a trowel or the like so as to have the same height as the road surface.
FIG. 6 shows a side cross-sectional view of a product obtained by arranging the reinforcing bar in the outer frame of the curb block, filling the concrete, and forming and completing the same. After that, if the concrete hardens, the curb is completed.

(Embodiment 2) FIG. 7 shows a second embodiment (embodiment 2) of the curb block according to the present invention. This embodiment consists only of uprights, and as shown in FIG.
It is composed of a character-shaped side part 10, a front part 20, and a back part 30, and the upper part and the bottom part of the upright part are openings. A fixing plate 50 and a fixing nail hole 51 are provided at the bottom similarly to the first embodiment, and a protrusion 11 and a concave portion to be fitted into the protrusion 11 are also provided at the side surface 10 similarly to the first embodiment. . In the case of this embodiment, the reinforcing bars installed inside the outer frame are mesh-shaped, and after the reinforcing bars are attached, the width stop is installed on the outer frame. This stop is the same as that in the first embodiment.

The above is the description of the embodiment of the outer frame of the curb block according to the present invention. As a material of the outer frame, plastic or light metal can be considered, but the material is not limited to this as long as it is lightweight.

[0013]

The outer frame of the curb block according to the present invention is light in weight, so that it can be easily installed on the ground even by elderly or non-powerful persons, and can be easily installed on the ground and connected with each other. Therefore, the transport and installation work is simpler than that of the conventional concrete block, and no skill is required.
Then, once the outer frame of the curb block is installed, it becomes a part of the curb and does not need to be removed, so that the cost and time required for the curb installation work can be reduced. In addition, by increasing the height of the curb block, the vehicle does not climb over the curb and enter the sidewalk, so that the danger is reduced not only for pedestrians but also for drivers. If the nighttime paint is applied to the front portion of the upright portion of the outer frame, it is useful for safe driving of the vehicle because the location of the curb can be recognized from the vehicle running at night. In addition, if the outer frame is made of plastic or light metal, the finish is beautiful and looks good.
