Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit roadbed material such as a sidewalk board used for paving a sidewalk of a general road, a sidewalk in a park, or other sidewalks, which is placed on the roof of a building or the like and shielded. The present invention relates to a unit roadbed material constituting frame used to form a unit roadbed material that can be used for heat or the like.

[0002]

2. Description of the Related Art A technique of holding a wooden brick or other member by using a frame and using it for paving has been proposed by the present inventor. Among them, the one close to the present invention is a base frame for sidewalk board construction (Japanese Patent Application No. 62-260887, Japanese Patent Publication No. 4).
No. -13482), this is "a large number of bottomed compartments are sectioned on the base frame main body,
It is a side frame for forming a sidewalk board in which a large number of vertical through-holes whose upper ends are closed so that they can be opened are continuously formed.

The sidewalk board base frame is the first to propose a technique for forming a sidewalk board using the base frame. Concrete is filled into the sidewalk board to form a sidewalk board, and the upper end of the partition wall is By removing it, the through hole formed in the partition wall is vertically penetrated to function as a water permeable hole. This is excellent because it does not lose water permeability for a long time.

[0004]

As described above, the above technique is excellent, but the connection of the sidewalk boards made by this technique is not limited to the connection protrusions provided on two adjacent sides. Only the structure in which the connection concave portions opened on the other two adjacent sides are fitted is proposed. In general, this is not particularly inconvenient, but it is desirable to make sure that the adjacent mutual connection is achieved while further improving the handling in transportation and the like. It is an object of the present invention to provide a frame body for constructing a unit roadbed material that solves the above problem.

[0005]

The gist of the structure of the present invention is that a bottom plate having a water-permeable hole and a frame body having peripheral walls on its four sides are provided on both sides of the frame body. A central line which forms a coupling recess having a recessed center portion, and which is a side protrusion that relatively protrudes laterally at positions adjacent to each of the coupling recesses and that is orthogonal to the side having the coupling recess. A side protrusion having a shape corresponding to the shape divided by, a coupling hole is formed in the side protrusion, and the side protrusions of the other two frame bodies are provided in the coupling recess. When the other side adjacent to the side of the frame in which the side projection is provided is adjacent to each other and engaged from the side, the two frames are formed in the coupling recess. It is a frame for unit roadbed material composition which comprises a connecting projection piece which will be fitted in a connecting hole of a side projection part of a body.

Since this frame is constructed as described above, it can be said that it has a generally drum shape or an eight-shape when viewed from above, with the body being thin due to the coupling recesses on both sides. In the lower part of the bottom plate of the frame body, it is preferable to configure a rainwater circulation groove composed of a cross groove crossing in the vertical and horizontal central portions and a half-width groove along two sides in a direction orthogonal to the side having the coupling recess. This rainwater circulation groove, both the cross groove and the half-width groove constituting the rainwater opening, open to the corresponding sides of the frame, respectively, as a result, to open on all sides, flowing from any opening, Alternatively, the rainwater flowing down from the upper part of the frame through the water-permeable holes can freely flow to the lower slope of the base. Needless to say, however, it is preferable that the cross groove and the half width groove are respectively continuous.

As described above, a large number of water-permeable holes are formed on the bottom plate by penetrating the front and back sides, but the size and shape are arbitrary. Further, the bottom plate is provided with an upper surface provided with a connecting cylinder body axially divided into a plurality of pieces.
The purpose is to spread the filler such as gravel and rubber chips together with concrete and other adhesives to strengthen the bond with the filler. It is preferable to configure a restriction stand around the connection cylinder body so as to prevent the expansion from unnecessarily expanding and falling.

Regarding the peripheral wall, the upper part of all the sides is
It is preferable to form an auxiliary peripheral wall whose inner surface coincides with or is located outside the outer surface of the lower peripheral wall. When configured in this way, after filling the gravel and rubber chips and other fillers together with the adhesive in this frame body and solidifying it, if the auxiliary peripheral wall is cut off with a blade, it is constructed with this frame body This is convenient because the frame itself cannot be seen from above after the unit roadbed material is laid on the foundation. Further, the auxiliary peripheral wall on the upper part of the peripheral wall is to be connected only by connecting sides formed at several places for easy separation, and a flange piece arranged at a right angle to this is provided on the outer surface of the auxiliary peripheral wall. It is more preferable that the projecting portion can be easily removed from the lower peripheral wall by picking and pulling with a pliers or the like.

The connecting projection is not limited to a particular structure, but may be composed of a tongue protruding outward from the peripheral wall and a locking claw hanging at the tip thereof. It is necessary to set the length of the tongue piece portion to a length that does not extend outside the side protrusion. Further, the coupling hole also needs to be capable of coupling in correspondence with the coupling protrusion, but is not limited to a special configuration other than that. When the coupling projection is configured as described above, the coupling hole can be configured by a hole into which the tongue piece can be inserted and a locking groove that engages the locking claw.

The frame can be molded from a suitable plastic. It is suitable to use polypropylene or the like to which a weather resistant agent is applied.

[0011]

Since the unit roadbed material constituting frame of the present invention is constructed as described above, it can be used as follows. This unit roadbed material frame is filled with a filler such as gravel, sand, or rubber chips, and is water-permeable while being bonded and solidified with concrete or another adhesive to form a unit roadbed material. Can be configured. At this time, as described above, when the connecting cylinder is provided upright on the bottom plate, when the frame is filled with a filler such as gravel or rubber chips, the divided cylinder pieces are divided. Can spread radially to enhance the bond with the filler

When the auxiliary peripheral wall is formed on the peripheral wall, the auxiliary peripheral wall is cut off with a blade after the filler such as gravel, sand and rubber chips is solidified. In this way, as described above, the frame cannot be seen in a plan view. When the auxiliary peripheral wall is joined to the peripheral wall only at a few connecting pieces and the flange is provided on the outer surface of the auxiliary peripheral wall, the auxiliary peripheral wall can be easily removed by grasping the flange with pliers and pulling it. it can. The brim piece can also serve as a reinforcing material that reinforces the auxiliary peripheral wall so as not to be easily deformed when the frame body is filled with the filling material. As described above, according to the frame of the present invention, it is possible to easily form a water-permeable unit roadbed material by filling it with a filler such as gravel, sand, or rubber chips.

Further, in the unit roadbed material constituted by the frame body as a constituent element in this way, when the transportation is carried out, the coupling projection piece is located in the coupling concave portion formed on the side portion of the frame body. , Easy to handle without any hindrance. This also applies to the state of the frame body before forming the unit roadbed material.

Since this unit roadbed material is constructed as described above, the area to be laid is dug down to an appropriate depth, gravel or the like is introduced and compacted, and sand is applied to adjust the unevenness. It is suitable to arrange the obtained flat water permeability on the lower ground. Adjacent to each other in the direction of the side without the connecting recess, the sides are arranged in contact with each other, and the side with the connecting recess is fitted with the side projections of the two unit roadbed materials in one connecting recess. To arrange. At this time, the coupling protrusions of the coupling recess are arranged while being inserted and coupled into the coupling holes of the side protrusions. In this way, one unit roadbed material is firmly connected in the lateral direction by the connection of the connection recess and the side protrusion, and the other is the connection of the connection protrusion and the connection hole in the vertical direction. Adjacent unit roadbed materials do not move easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, the frame body 1 has a configuration in which the center portion on both sides of a flat rectangular bottom plate 2 is recessed to form a substantially hourglass shape, and the peripheral wall 3 is raised along the edge thereof. It is basic. An auxiliary peripheral wall 4 is attached to the upper end of the peripheral wall 3 over the entire circumference. The auxiliary peripheral wall 4 is positioned such that its inner surface is slightly outside the outer surface of the peripheral wall 3, as can be seen clearly in FIG. 3, and in particular, as can be seen in FIG. The upper end of the peripheral wall 3 and the lower end of the auxiliary peripheral wall 4 are connected at 16, 16 ,. Further, a flange piece 5 is provided on the lower portion of the outer surface of the auxiliary peripheral wall 4 so as to extend outward over the entire circumference. The auxiliary peripheral wall 4 is reinforced and is pinched with pliers or the like when removing the auxiliary peripheral wall 4 as described later.

The recesses on both sides of the frame 1 constructed as described above serve as coupling recesses 6, and the protrusions on both sides thereof form side protrusions 7, 7. As shown in FIG. 1, the shape of the coupling recess 6 and the side protrusions 7, 7 viewed from the plane is such that the two side protrusions 7, 7 are adjacent to each other in the direction orthogonal to the side where the two side protrusions 7, 7 are located. When they are fitted into the coupling recess 6 while being brought into contact with each other, the shape is such that a close fitting relationship can be obtained.

The bottom plate 2 has a large number of water-permeable holes 8, 8 ... Penetrating the front and back sides, and as shown in FIGS. And a rainwater flow groove 9 composed of half-width grooves 9b, 9b along two sides orthogonal to the side having the coupling recesses 6, 6,
Further, on the upper surface of the bottom plate 2, reinforcing ridges 10 are provided upright along the edges of the rainwater circulation grooves 9. Four connecting cylinders 11, 11 ... Are erected on the upper surface of the bottom plate 2.
Each of the connecting cylinders 11 is set up in a partition partly including the side projections 7, 7, ... Partitioned by the reinforcing ridge 10. As shown in FIGS. 1 and 3, the connecting cylinder body 11 has a circular regulating base 11a on the periphery thereof, and a connecting cylinder body 1 composed of four divided cylinder pieces 11b, 11b ... Inside thereof.
It was the launch of 1.

In the coupling recesses 6, 6 on both sides of the frame body 1,
Two connecting projections 12, 12 are formed so as to project from the peripheral wall 3 so as to be located on both sides of the cross groove 9a that opens at this position. In addition, at the tips of the coupling projections 12, 12, the
As shown in, the locking claw portion 13 is hung down. The length of the connecting projection 12 is determined so as not to project outward from the side projection 7. On the other hand, in the side projections 7, 7 on both sides of the coupling recesses 6, 6, a coupling hole 14 is formed in the peripheral wall 3 adjacent to the half-width groove 9b. As shown in FIG. 3, the coupling hole 14 is composed of a hole into which the coupling projection 12 can be inserted and a locking groove 15 that engages the locking claw 13.

The frame body 1 and the constituent elements integrally formed with the frame body 1 are molded using polypropylene having a weatherproofing agent.

In this embodiment, however, since it is constructed in this way, the frame 1 is filled with a filler such as gravel, sand, or rubber chips to keep the water permeability and other materials such as concrete. The unit roadbed material 18 can be configured by bonding and solidifying with an adhesive or the like.

In this example, the gravel 17 is filled and solidified with concrete so that a small gap is left between the gravel 17 so as to ensure water permeability, and the unit roadbed material including the frame body 1 as a part of the element. Make up 18. When charging the gravel 17,
The connecting cylinder 11 is radially expanded by the gravel 17, and the divided cylinder pieces 11b, 11b ... Are thrust into the gravel 17 obliquely or laterally. Then, when the gravel 17 is solidified with concrete, the divided cylinder pieces 11b, 11b ... Are inserted into the solidified gravel 17 to be joined, so that the gravel 17 is securely fixed in the frame 1.

After the gravel 17 is solidified in this way, the auxiliary peripheral wall 4 is removed from the peripheral wall 3 by pinching the flange piece 5 with pliers or the like and pulling it. The auxiliary peripheral wall 4 is a connecting piece 16,
It is easy to remove since it is only connected to the peripheral wall 3 by 16. When the auxiliary peripheral wall 4 is removed in this way,
The peripheral wall 3 located below it is hidden by the solidified gravel 17 and disappears. That is, as described above, the auxiliary peripheral wall 4 is constructed so that the auxiliary peripheral wall 4 is outside the peripheral wall 3, more specifically, the inner surface of the auxiliary peripheral wall 4 is slightly outside the outer surface of the peripheral wall 3, so that the gravel 17 is reached to this position. Is filled and solidified. Thus, the permeable unit roadbed material 18 filled with the gravel 17 can be easily constructed.

Further, in the unit roadbed material 18 constituted by the frame body 1 as a constituent element as described above, the coupling projection 12 is formed in the coupling recess 6 formed on the side portion of the frame body 1 during transportation. As it is located, it is easy to handle without any hindrance. Further, the frame body 1 before constituting the unit roadbed material 18
This is the same in the state of.

The unit roadbed material 18 has such a structure and can be used for paving a sidewalk or the like, like a general sidewalk board. When this unit roadbed material 18 is used for pavement, in order to secure water permeability to the foundation, a gravel foundation is used in which the target area is slightly dug and then gravel is arranged and compacted.

As shown in FIG. 4, the unit roadbed materials 18 are arranged on the gravel substrate in the direction of the sides where the adjacent connecting recesses 6 are absent, as shown in FIG.
As for the side having the coupling recess 6, the side projections 7, 7 of the two unit roadbed materials 18, 18 are arranged so as to fit into one coupling recess 6. At this time, the coupling projection 12 of the coupling recess 6,
12 are inserted into and coupled to the respective coupling holes 14 of the side protrusions 7, 7. When the laying of the unit roadbed materials 18, 18 ... Is completed in the target area in this manner, the paving is completed.

With this arrangement, however, the adjacent unit roadbed members 18, 18 are prevented from moving in the lateral direction due to the connection between the connecting recesses 6 and the side projections 7, 7, and the connecting projections are also connected. Due to the coupling of the pieces 12 and 12 and the coupling holes 14 and 14, the adjacent ones cannot move vertically relative to each other. The coupling tongue 12 and the coupling hole 14
The combined state with and is as shown in FIG.

In this embodiment, since the unit roadbed material 18 is made water-permeable, the paved road surface made of this material has good water-permeability and rainwater overflows on the road surface even in the case of rain. Cannot happen easily. That is, in case of rain, rainwater flows down through the gaps of the solidified gravel 17 onto the bottom plate 2 of the frame body 1, and the water permeation holes 8 and 8 formed in the bottom plate 2 further.
It will flow down onto the ground through. A part of the material flows down from the gap between the unit roadbed materials 8, 18 ...

Thus, the rainwater first flows down onto the base, and the rainwater flowing down onto the base gradually permeates underground.
When the amount of precipitation per unit time is the largest and exceeds the amount of permeation per unit time, it will remain on the substrate, but these rainwater will vertically and horizontally spread on the lower surface of the bottom plate 2 of the frame. A rainwater distribution groove 9 is formed, and unit roadbed materials 18 and 1
When laying 8 ..., the unit roadbed materials 18, which are adjacent to each other,
Since they are connected to and communicate with each other, they flow downward through the rainwater circulation grooves 9, 9 ... And are easily drained to a side groove or the like formed on the road edge.
