DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to arrange a pavement or a floor surface with treads or the like in an area where an outdoor is required to be laid such as a sidewalk or a parking lot or an area where an indoor is required to be installed. Related to a composite tread.

[0002]

2. Description of the Related Art A composite tread is constructed by holding treads such as a single wooden brick with a laying frame, and laying these to form a wooden brick pavement and a pavement with other treads. Relates to the proposal of the present inventors. The following is a specific example of a number of applications proposed for this type of technology.

That is, the above-mentioned laying frame generally comprises a holding section in a frame body, and a partition wall for partitioning the holding section is formed by a diagonally downward elastic piece of elasticity. After holding the wooden brick in the holding section, it is laid in a predetermined area to complete the pavement of the wooden brick (Japanese Patent Laid-Open No. 33301/1988).

[0004]

The conventional laying frames for wooden bricks and other treads are constructed as described above, and are used for laying speedy and flat treads and treads. With respect to (1), an intended purpose such as absorption of expansion and contraction of wooden bricks due to a change in moisture state can be achieved.

[0005] Here, a composite tread board incorporating treads and the like beyond the laying frame is constructed so that it can be used both indoors and outdoors as well as outdoors and forms a walking surface on which a stumbling hardly occurs. Providing is an issue to be solved.

[0006]

The gist of the structure of the present invention is that a plurality of holding sections for holding a plurality of treads alone in a frame corresponding to an arrangement at the time of laying are formed on a frame body, and each holding section is provided. A composite tread that holds a tread alone so as to be movable in a horizontal direction within a range limited to the holding section.

[0007] The frame may be formed in a polygonal shape such as a hexagon when viewed from a plane, but a quadrilateral is suitable for convenience in laying. Above all, it is more convenient to form a square than a rectangle.

Needless to say, the holding section is formed in a planar shape corresponding to the planar shape of the target treadle alone.
Of course, in order to be able to move a little in the holding section, it is configured to have an internal size slightly larger than the plane size of the target tread sole. The general shape is a rectangle or a square corresponding to the shape of a general treadle. Furthermore, the number of holding sections is not particularly limited. For example, if the target treadle unit has a square planar shape, nine holding sections can be configured in three rows and columns. In this case, by forming the partition walls in a lattice shape, the holding partitions can be arranged vertically and horizontally as described above. The partition wall is common between adjacent holding partitions. Further, for example, it is also possible to adopt a configuration in which about three rows of holding sections for holding the flat rectangular treads alone are arranged so as to be in contact with the longitudinal side surfaces.

Although a bottom plate may be simply formed at the bottom of the holding section, it is appropriate to form a pedestal for receiving the back surface of the target treadle alone. In any case, a water-permeable hole or a slit is formed in a part so that rainwater or other water that has entered the holding compartment can flow out from the bottom. When the receiving stand is configured, for example, it is appropriate that the receiving stand is configured to be slightly raised from the bottom of the holding section. In the case where the holding section is a flat square, it is appropriate to form one cradle at the center thereof. If the holding section is a flat rectangular section or the like, it is appropriate to arrange a plurality of receiving stands at appropriate intervals depending on the length. The cradle is configured to be supported by a plurality of arms extending from near the lower part of the partition wall of the holding partition. Both sides of each arm are the water-permeable holes or water-permeable slits.

[0010] As a configuration for holding the tread sole so as to be movable in the horizontal direction within a range limited within the holding section, various configurations can be freely adopted as long as the operation is ensured. Can be. For example, each of the holding sections is provided with a flange piece that protrudes inward on the inner surface of the partition wall that partitions the holding section, while the tread sole itself has the flange piece when it is loaded into the holding section. Engagement grooves are formed on the four sides to allow engagement, and a gap is formed between the lower portion of the engagement groove and the partition wall of the holding section when the treadle is inserted into the holding section. The engaging groove is retracted so that the upper portion of the engaging groove is formed as a projecting portion that projects so as to cover a part of the upper end of the partition wall. A configuration in which a flange piece of a partition wall is inserted into the engagement groove of the tread alone can be adopted.

When the frame is installed on a pavement ground, it is appropriate to form a connecting male portion and a connecting female portion for connecting adjacent ones to each other. Needless to say, the connecting male portion and the connecting female portion are configured to be connectable to the connecting female portion and the connecting male portion of the adjacent frame, respectively. In the case where the frame is formed in a quadrilateral such as a plane square or a rectangle, the simplest example is, in each side, a symmetrical positional relationship, and one position corresponds to the thickness of the peripheral side wall. There is a configuration in which a protrusion (a male connection portion) is protruded, and a fitting hole (a female connection portion) into which the protrusion can be fitted is formed in the other position. With such a configuration, adjacent frame bodies can be connected to any side. This is particularly significant when the pattern of the pavement surface or floor surface differs depending on the direction, such as when the treadle held by the frame is a flat rectangular one.

The frame is suitably molded from a plastic material having sufficient strength.

[0013] Further, each of the tread soles is inserted and held in the holding section of the frame. The loading of the tread sole is performed by pushing the tread into the holding section of the frame placed upward from above. The tread sole is held so as to be movable in the horizontal direction within a range limited in the holding section, according to the specific configuration of each tread. As described above, each holding section is provided with a flange piece that protrudes inward on the inner surface of the partition wall that separates the holding section, while the tread sole has a configuration in which an engaging groove is formed on the peripheral side thereof. In this case, the tread sole is inserted into the holding section, and the flange piece of the partition wall is inserted into the engaging groove of the tread sole.

Since the composite tread of the present invention is constructed as described above, it can be used for forming an indoor floor surface of a building or for forming an outdoor tread pavement.

For example, laying work on a sidewalk or other area is performed as follows. First, an appropriate foundation such as a gravel foundation or a concrete foundation is formed. The above-mentioned gravel ground, after digging down the required area, put the gravel,
Sufficiently rolled for a smooth finish. The concrete foundation may be similarly dug down in a required area, cast in by a general method, and smooth the upper surface.

On the gravel or concrete substrate as described above, a composite tread board constituted by holding a plurality of tread boards alone in the frame is arranged vertically and horizontally. When the connecting male part and the connecting female part are formed on the peripheral side of the frame, they are arranged so as to connect adjacent ones with each other as follows. First, a number of composite treads corresponding to the number of composite treads arranged at the connection direction end of the existing composite tread group are arranged in a row and connected. Naturally, this connection is made by connecting one connecting male part and connecting female part of the adjacent composite treading frame to the other connecting female part and connecting male part. Is connected to a composite tread in a row at the end of the existing composite tread group by connecting the connecting male part and the connecting female part to each other in the same manner as described above.

The installation is completed by performing such an operation over a necessary area. Therefore, smooth pavement using a plurality of treads alone can be performed very easily and efficiently even by a layman by arranging multiple treads in series. The same applies to the case where an indoor floor surface is configured.

By the way, in this composite tread, since the tread alone loaded in each holding section is movable in the horizontal direction within the respective range, as described above, the composite tread is constituted by the composite tread. Even if the pedestrian walking on this paved path hooks a toe or the like at the corner of one of the treads, the tread only moves within a certain range in the horizontal direction and the feet move. There is an advantage that a stumbling is prevented without being restricted by force.

Thus, a smooth pavement made of the wooden bricks 5, 5,... Can be completed by an extremely simple operation of arranging the frames 1, 1,.

By the way, in the composite tread of this embodiment, the wooden bricks 5, 5,.
Are movable in the horizontal direction within the range of the holding section 2, respectively. Therefore, as described above, even if the pedestrian walking on the pavement road constituted by the composite treads may hook a toe or the like on the corner of any of the wooden bricks 5, 5,. However, the wooden brick 5 does not move and does not forcibly restrict the movement of the foot, so that a stumbling can be avoided. Further, since the upper side of the wooden brick 5 is extended as the overhanging portions 14, 14, there is an advantage that a part of the upper end of the partition wall 3, 3,.

[0032]

According to the present invention, it is possible to complete a smooth floor or pavement with the treads by a very simple operation of arranging the frames constituting the composite treads in a row. Moreover, on the pavement surface obtained by the obtained composite tread, the tread alone can freely move in the horizontal direction within the range of the holding section. Therefore, when walking, even if the tip of the shoe is hooked on this, the sole of the tread moves and does not forcibly restrict the movement of the foot,
Pedestrians can avoid stumbling even in such a case.
