Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is applicable to paving by holding a plurality of concrete slabs, various types of tiles, various tiles called interlocking tiles, or treads such as real bricks. This relates to a frame for laying treads used in

[Prior art] Stepping boards, such as bricks, concrete slabs, or tiles, are held by a laying frame in a manner that corresponds to 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 pavements using treads such as bricks was generally developed and proposed by the present inventor (Jitsukonuma No. 61-44230, Jitsukondoma No. 61-
No. 107080, Jitsuginoma No. 62-85126, Patent Application No. 1986
No. 3-173614, and others, none of which are publicly known).

[Problems to be Solved by the Invention] When paving with various types of treads is created using a paving frame as described above, the paving frame itself is molded from a resilient material, such as plastic. Because of its elasticity, it provides some elasticity to the paved road surface, giving it the advantage of giving a softer walking feel.

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. Moreover, 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 that using real 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 this brick that have poor elasticity.

[Means to solve the problem J What is the gist of the configuration of the present invention?

The frame body is configured with holding sections for a plurality of treadboards corresponding to the arrangement at the time of installation, a bottom plate having a large number of water permeable holes is formed in each holding section, and an elastic member is arranged on the bottom plate. death,
Further, this is a frame for laying footboards, in which an elastic collar piece extending diagonally downward inward from the compartment wall that divides the holding compartment is provided.

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. - The convergence will most likely be a quadrilateral such as a square or a rectangle, but of course it is not limited to this, and there is no problem in taking various complicated shapes depending on the shape of the target tread.

Furthermore, it is not necessary for the above-mentioned partition walls to be erected in all parts on the lines that constitute the partitions. be.

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.

It is preferable that the four sides of the frame include a male connecting part on a pair of adjacent sides with the negative corner between them, and a female connecting part on the other pair of adjacent sides. Of course, you can adopt any structure you want.

However, for example, the bottom plate can be extended from the corresponding side and the tip enlarged to form an appropriate shape. 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 may be used as the elastic member, or a large number of elastic particles may 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 particles, so there is no need to consider any means of permeation.The latter can be constructed at low cost, such as by crushing waste synthetic rubber. You can also do it.

[Operation 1] Since the present invention is constructed as described above, each holding section holds the treadboards, and then the paved road surface is completed by consecutively arranging the laying frames in the target area. 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 loading and holding treads in a large number of laying frames.It is best to perform this work by hand.If the treads are large and difficult to insert, first remove the treads. The lower part of the holding compartment is charged into the holding compartment and then hammered in with a mallet or the like.Since the compartment wall of the holding compartment is formed with an elastic collar piece that faces diagonally downward inward, it is possible to Regardless of the operation, the treadle boards can be loaded without any inconvenience, and the loading process can generally be carried out smoothly. Further, the loaded footboards are securely held in the holding compartment by the flange piece.

After holding the treads in the required number of laying frames in this way,
Install the laying frames in the target area one after another.

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 treads shall be successively arranged on the above-mentioned base. 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 complete when the subsurface of the target area is covered with the paving frame.

The paved road surface completed in this way has elasticity because an elastic member is placed between the bottom surface of the treads and the bottom plate of the holding section, giving the treads vertical elasticity. This results in an extremely good walking feeling.

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

As shown in FIG. 1, nine holding sections 2.2, each having a square plan view, are arranged vertically and horizontally in a frame l having a square plan view.

Each holding section 2.2... is divided only at each of its four corners, and the partition walls that partition each holding section 2.2... are located at the corners of the frame 1.

By the action of the above-mentioned collar pieces 4, 4, etc., the concrete flat plate 10 can be pushed into the holding section 2 a little, and then it can be charged relatively easily by hitting it with a mallet or the like. Further, the concrete flat plates 10, lO... charged in the holding compartments 2.2... in this way are connected to the above-mentioned flange pieces 4.
4... provides an effect to prevent removal and is reliably held within the holding section 2.2....

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

In addition, the above target area has a gravel base 1 that has ensured water permeability in advance.
