Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a concrete flat plate, various types of tiles, various types of interlocking tiles, or a plurality of treads such as wooden bricks. This relates to a frame for laying treads used in paving.

[Prior art] Stepping boards such as wooden bricks, concrete slabs, tiles, etc. are held by a laying frame in accordance with the arrangement at the time of laying, and the laying frame, which holds the stepping boards in this way, is connected to the target area. By doing so, the practical technology for creating pavement with treads such as wooden bricks was generally developed and proposed by the present inventor (Utility Application No. 61-44230, Utility Application No. 61-107080). , Utility Application No. 62-85126, Patent Application No. 173614-1983, and others.
Note that none of these are publicly known. ).

[Problem to be Solved by the Invention] When paving with various types of treads is created using a paving frame such as the one described above, the paving frame itself is made of a resilient material, such as plastic. Because of its elasticity,
This gives the paved road surface some elasticity, which has the advantage of softening the feeling of walking.

By the way, as mentioned above, there are various materials for treads, such as wood such as wood bricks, concrete, stone, and bricks. Among them, wood bricks, which are made of wood, have some elasticity themselves. To,
The paved road using the above-mentioned paving frame has sufficient elasticity, and an extremely good walking feeling can be obtained.
Paved roads using the above-mentioned paving frames that use tiles and other non-resilient treads are also more resilient and provide a better walking experience than conventional paved roads that are simply fixed to the base with mortar, etc. However, it cannot be compared to using wooden bricks.

It is an object of the present invention to provide a laying frame that can provide sufficient elasticity even when paving with treads other than wood bricks, which have poor elasticity.

[Means for Solving the Problems] The gist of the configuration of the present invention is that a frame body is configured with a plurality of holding sections for treadboards corresponding to the arrangement at the time of laying, and a large number of holding sections are arranged in each holding section. installation of treads comprising a bottom plate having water permeability holes, an elastic member disposed on the bottom plate, and an elastic flange extending diagonally downward inward from the partition wall that partitions the holding partition; It is a frame.

Although the frame is not limited to a specific planar shape, a quadrilateral planar shape is suitable for convenience of handling. Plastics are suitable as the material because they are easy to mold and have high elasticity.

The planar shape of the holding section is determined according to the planar shape of the treads to be held. Generally, it will be a quadrilateral shape such as a square or a rectangle. However, it is of course not limited to this, and there is no problem in adopting various complicated shapes depending on the shape of the target tread.

Further, the partition wall does not need to be erected at all parts on the line forming the partition. It is sufficient to erect them in such a way that they are centered on each corner on the line forming the compartment and extend forward and backward.

Needless to say, the shape of the water permeable hole is arbitrary. However, since there is no reason to make the shape particularly complicated, it is appropriate to form the hole into a simple circular hole.

On the four sides of the frame, a pair of adjacent sides with one corner interposed therebetween is preferably configured with a connecting male part, and the other pair of adjacent sides is preferably configured with a connecting female part. Of course, the male connection part can have any configuration, but for example, it can be configured in an appropriate shape with the bottom plate extended from the corresponding side and the tip enlarged. On the other hand, the female connection part may be formed as a notch in the bottom plate located inside the corresponding side, with a shape corresponding to the shape of the male connection part.

Furthermore, the reason for the existence of the elastic member is to impart vertical elasticity to the treads loaded into the holding compartment. Any aspect may be used as long as it does not inhibit water permeability and does not inhibit water permeability. for example,
An elastic sheet can be used as the elastic member, and a large number of elastic particles can also be used. In the case of adopting the former method, it is necessary to drill a large number of water permeable holes evenly through the elastic sheet from top to bottom. If the latter is adopted, rainwater etc. can pass between the grains, so there is no need to consider a water permeation means in particular. The latter can also be constructed at low cost by crushing waste synthetic rubber.

[Function] Since the present invention is configured as described above, the paved road surface is completed by holding the treadboards in each holding section and arranging the paving frames in series in the target area as follows. can be done.

Although the stepboards may be loaded and held in the installation frame after the installation frame is laid in the target area, it is more efficient to hold the treadboards in advance before installation.

Therefore, a necessary number of laying frames are prepared in advance for paving the target area, and treads are loaded and held in each holding section. It is best to automate this work when a large number of laying frames are to be loaded and held with treadboards. If this is done by hand and the treadboards are somewhat large and difficult to insert, the lower part of the treadboards may be inserted into the holding compartment first, and then hammered in with a mallet or the like. Since the compartment wall of the holding compartment is formed with a resilient collar piece that faces diagonally downward inward of the compartment, the treads can be loaded without any inconvenience despite the above-mentioned operation. The admission process is generally smooth. Further, the loaded footboards are securely held in the holding compartment by the flange piece.

After the necessary number of laying frames hold the treadboards in this manner, the laying frames are sequentially installed in the target area.

It is necessary to prepare a base for laying in advance in the above-mentioned target area. As a general rule, the base should be water permeable. For example, the target area is dug, gravel is poured into it and compacted, then sand for unevenness adjustment is placed on top of it, and then it is further compacted.

In this way, a permeable gravel base is created.

The holding frames for the above-mentioned treadboards shall be successively arranged on the above-mentioned base ground. When a connecting male part and a connecting female part are formed on each side, the adjacent sides of the installation frame are connected to each other by these parts. Paving is completed when the subsurface of the target area is covered with the paving frame.

The paved road surface completed in this way has an elastic member placed between the bottom surface of the treads and the bottom plate of the holding section.
Since the footboards are given elasticity in the vertical direction, the road surface has elasticity, and the walking feeling is extremely good.

[Example] An example of the present invention will be described below based on the drawings.

As shown in FIG. 1, nine square holding sections 2, 2, .

Each holding section 2, 2... shall be divided only at each of its four corners, and the partition walls which partition each holding section 2, 2... shall be those located at the corners of the frame 1. The T-shaped partition walls 3a, 3a... are located along the sides, and the T-shaped partition walls 3b, 3b...
Those located inside are the ten-shaped partition walls 3c, 3c...

Further, on the bottom plate 5 of the holding sections 2, 2..., as shown in FIG. 2, a large number of elastic particles 7, 7... are arranged. The elastic particles 7, 7... are formed by crushing chloroprene-based synthetic rubber.

Further, as shown in FIG. 1, a pair of adjacent sides with one corner sandwiched between the four sides of the frame 1 are provided with connecting male portions 8, each having an enlarged tip. The male connection part 8 is constructed by extending the bottom plate 5 of the holding section 2. On the other hand, on the other pair of adjacent sides, female connection parts 9 each having a shape corresponding to the male connection part 8 are formed. This connection female part 9
is constructed by cutting out the area from the corresponding side to the bottom plate 5 of the holding section 2 located inside the corresponding side.

The frame body 1 and the above-mentioned components attached thereto, except for the elastic particles 7, 7, . . ., are molded from plastic mainly made of polypropylene.

Since the laying frame of this embodiment is constructed as described above, each holding section 2, 2 is constructed as described in detail below.
It is possible to create a paved road surface by holding treadboards with dimensions and shapes corresponding to the respective shapes, that is, treadboards with a square plan view, and then arranging them in series in a target area.

Here, an example will be described in which small concrete flat plates 10, 10, . . . are employed as the treads.

First, a necessary number of laying frames are prepared in advance for paving the target area, and the concrete flat plates 10, 10, . . . are charged and held in each of the holding sections 2, 2, . The concrete flat plates 10, 10... are normally charged into the holding compartments 2, 2... by the compartment walls 3a, 3a.
..., 3b, 3b..., 3c, 3c... can be easily performed even by hand due to the action of the collar pieces 4, 4... configured diagonally downward. Of course, if the concrete flat plates 10, 10... are slightly larger than the specified dimensions, it may be difficult to charge them, but even in such cases, the above-mentioned collar pieces 4, 4
Due to the action of..., the concrete flat plate 10 can be pushed into the holding section 2 a little, and then it can be charged relatively easily by being hammered in with a mallet or the like. Furthermore, the concrete flat plates 10, 10... charged into the holding sections 2, 2... are provided with a retaining effect by the action of the above-mentioned collar pieces 4, 4..., and are reliably charged into the holding sections 2, 2... held within.

After repeating such operations to hold the concrete flat plates 10, 10, . . . on the necessary number of laying frames, the laying frames are successively installed in the target area.

Note that a gravel base 11 with water permeability ensured is provided in advance in the target area. This is constructed by digging the target area, filling it with gravel and compacting it, placing sand on top of it for unevenness adjustment, and further compacting it.

Thus, the laying frames holding the concrete flat plates 10, 10, . . . as described above are sequentially placed on the gravel base 11.

A laying frame to be installed subsequently to the existing laying frame is laid while joining the side where the female connecting part 9 of the latter is formed to the side where the male connecting part 8 of the former extends. The latter laying frame is lowered at the above position, and the male connecting part 8 of the former laying frame is fitted into the female connecting part 9 of the latter. By repeating such laying work, the gravel base 11 of the target area is
