Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a sidewalk board base frame for constructing a water-permeable sidewalk board by filling the frame with mortar or inserting treads. It is.

[Prior Art] Currently, there is no concrete sidewalk board constructed by filling a base frame with mortar.

The applicant in this case is not yet publicly known. A patent application was filed for technology related to this on October 16, 1988.

This is a sidewalk board structure in which the base frame main body is divided into a number of bottomed compartments, and the division wall that divides each of the compartments is formed with a number of vertical passage holes whose upper ends are closed so that they can be opened. It is the base frame.

Furthermore, the applicant or the inventor has filed numerous patents or utility model registration applications regarding the technology of constructing water-permeable sidewalk boards by inserting treads into the base frame.

Briefly, the frame body has sections for holding treads, wooden bricks and other treads are charged and held in each section, and then the entire frame is laid on the base ground. The plan is to pave with bricks, etc. A hole is formed in the bottom of each holding section to pass through the holding section from top to bottom, and a slight gap is formed on both sides of the partition wall between the holding section and the wooden bricks, etc. to be held.

Therefore, accurate laying on the base, ease of laying work, and water permeability of the paved road surface are ensured.

Many proposals have been made for concrete sidewalk boards that are designed to be water-permeable by modifying their constituent materials.

[Problems to be Solved by the Invention] The first technique proposed by the present applicant has the advantage that good water permeability can be obtained by itself, and that even an amateur can accurately manufacture concrete sidewalk boards.

However, in addition to this, from another point of view, there is also a need for a base frame with a similar structure that achieves water permeability without the need for processing or other operations on the base frame itself.

Most of the conventional water-permeable sidewalk boards mentioned at the end of the above are designed to ensure water permeability by devising the composition of the constituent materials, so they are not easy to manufacture and also tend to clog early after construction. However, it has the problem of losing water permeability.

However, in this invention, the base frame is constructed to be able to hold the treads, and it is also possible to charge and fill this with mortar to construct a concrete sidewalk board.At the same time, it is simple and reliable. The purpose is to ensure water permeability.

[Means for Solving the Problems] The gist of the configuration of the present invention is that the base frame main body is configured in the shape of a container with an open top, and that the outer wall of the base frame is provided with other adjacent walls when it is laid on the substrate. This is a sidewalk board base frame in which a plurality of spacer pieces are protruded to create a water permeable gap between the base frame body and the outer wall.

The planar shape of the base frame main body can be freely determined in the same manner as that of possible treads. Square or rectangular shapes are common. However, as mentioned above, it can be formed into a hexagonal shape or any other arbitrary shape. Naturally, the dimensions of each part, such as the height, are also free.

The spacer piece projects from the outer wall in a direction perpendicular thereto. For example, the spacer pieces are configured in a plate shape, and a large number of plate-shaped spacer pieces are made to protrude from the outer wall in a right angle direction. If the base frame body is a quadrilateral such as a square plane or a rectangle, plate-shaped spacer pieces of the same size are arranged protruding at a right angle on two adjacent sides at a constant pitch, and on the other two sides. In this case, a plate-shaped spacer piece of the same size is protruded and arranged at the same pitch, shifted by half a pitch from the above arrangement.

With this configuration, when the sidewalk board base frames are installed consecutively on the base, if the adjacent sidewalk board base frames are made to adjoin the outer walls having the spacer pieces that are shifted by half a pitch from each other, It is advantageous that the spacer pieces are inserted alternately between the spacer pieces of each other.

When this sidewalk board base frame is used to construct a concrete sidewalk board by filling the base frame body with mortar, the bottom of the base frame body is filled with mortar near its center. Preferably, a holding protrusion is provided to hold the mortar after solidification.
The holding protrusion has an enlarged upper part. It is preferable that ribs having a lower height extend radially from the lower part of the holding protrusion to the lower part of the outer wall. In addition, a large number of drainage holes leading to the back surface should be bored and scattered at an appropriate density in the bottom.

The general structure is designed to be compatible with both cases in which concrete sidewalk boards are constructed by filling the base frame body with mortar, and cases in which treads of the appropriate size and shape are inserted into the base frame body. In this case, the above-mentioned holding protrusion is not provided. However, the above-mentioned ribs and drain holes constitute. With this configuration, treads such as wooden bricks or various types of concrete slabs can be inserted and held. Of course, it is also possible to construct a concrete sidewalk board by filling it with mortar.

On the outside of the outer wall of the base frame main body, it is preferable that male connection parts be formed on two adjacent sides outside the spacer piece as necessary, and female connection parts are formed on the other two adjacent sides.

It is preferable that the base frame body and each of the constituent elements formed thereon be integrally molded from a plastic material.

[Function] Since the present invention is configured as described above, it can be used in the following manner.

First, using the sidewalk board base frame of the present invention, mortar is charged and filled into it to form a concrete sidewalk board, or tread boards are inserted and held.

To explain the former method, first, the base frame body is placed in a predetermined location facing upwards, and mortar is poured from above. Pour mortar completely into the base frame body, and use a ruler board or the like with a length that exceeds the width between the outer walls of the base frame body to cover the top surface of the mortar. By moving it from one end to the other end, the mortar beyond the upper end of the outer wall is removed. In this way, the top surface can be made flat.

If a large number of drainage holes are provided in the bottom of the base frame main body as described above, the water in the mortar will drain from these holes below the bottom, which is convenient for drying and solidifying the water. Further, when the mortar hardens, if a holding protrusion is formed at the center of the bottom of the base frame body, it will be firmly fixed to this and will not come off.

In the case of the latter usage, it is sufficient to simply insert treads of the corresponding dimensions into the base frame body.

In either case, the spacer pieces outside the outer wall remain intact. When laid as described below, it is possible to easily construct a concrete sidewalk board or treadboard holder having a water-permeable gap outside the outer wall.

In any case, since it is constituted by the sidewalk board base frame, it can be extremely easily made to have accurate dimensions and shape.

The concrete sidewalk board or treadle holder constructed in this manner can be used by laying it on a sidewalk, etc., in the same way as a general one.

This will be briefly explained.

The base is naturally made to be water permeable. A gravel base etc. is suitable.

For example, the relevant area is dug down a little, gravel is poured into it, the gravel is compacted, and then sand is placed on top of it for unevenness adjustment. After this, roll it again to make the top surface flat.

The concrete sidewalk board, etc. is laid on the gravel base. The concrete sidewalk boards that were laid first are laid one after the other, with the outer walls of the base frame bodies having spacer pieces shifted by half a pitch in correspondence with each other. The spacer pieces of each outer wall are inserted between the opposing spacer pieces.
In this way, concrete sidewalk boards and the like are arranged vertically and horizontally on the gravel base.

Thus, when constructing concrete sidewalk boards, etc. using the sidewalk board base frame of the present invention and paving with them, water permeability gaps are surely created at positions corresponding to the joints of the laid concrete sidewalk boards, etc. This results in a pavement with extremely good water permeability.

To explain this in more detail, when the outer walls of adjacent sidewalk board base frames are installed, they are separated by spacer pieces, and gaps are created between the spacer pieces.
Therefore, rainwater and the like fall onto the ground surface through this gap, and if the groundwork is permeable as described above, the rainwater and the like will further permeate underground.

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

As shown in FIGS. 1 and 2, the base frame body 1
is constructed in the shape of a square container with an open top.

The protruding length of ... is 10 mm.

The bottom part 4 of the base frame main body 1 is provided with ribs 5, 5 which are arranged diagonally when viewed from above. Also, a large number of drain holes 6, 6, . . . communicating with the lower surface are bored and arranged evenly.

The base frame main body 1 and each component constructed thereon are integrally molded from plastic material.

Since this embodiment is configured in this way, it can be used as follows.

First, an example will be described in which a concrete sidewalk board is constructed by charging mortar into the base frame body 1 and laying it on a gravel base.

First, a plurality of sidewalk board base frames are placed in a predetermined work place with the tops of the base frame bodies 1, 1... facing upward,
Pour mortar into the interior from above. Pour mortar completely into the base frame bodies 1, 1... and scrape off excess mortar using a ruler board or the like with a length that exceeds the width between the outer walls 2a and 2b of the base frame body 1. . That is, the above-mentioned ruler plate etc. are attached to the outer walls 2a on both sides,
2b in a bridging manner and moving it from one end to the other, the outer walls 2a, 2a, 2b,
Remove excess mortar beyond the top of 2b.
In this way, the top surface can be made flat.

In the above process, the sidewalk board base frames are placed one after another on a suitable conveyor (belt conveyor, roller conveyor, etc.), and while being transported to the next process work position,
Mortar is poured into the base frame bodies 1, 1... of each sidewalk board base frame, and as the mortar progresses further, as described above, a ruler plate etc. arranged perpendicular to the conveyor is placed in the base frame bodies 1, 1... It is also possible to automate this process by bringing the mortar into contact with the upper ends of both outer walls 2a and 2b, and scraping and smoothing the mortar that exceeds these.

As described above, as shown in FIG. 3, mortar is filled into the base frame main body 1 and the upper surface is made smooth.

During the above process, the bottoms 4 of the base frame bodies 1, 1... are provided with a large number of drainage holes 6, 6... as described above, so that moisture in the mortar is drained from these holes to the bottoms. This will allow it to flow downward and solidify smoothly. Further, the ribs 5, 5 are intended to reinforce the bottom portion 4, but at the same time, they also play a role of holding the charged mortar. After this, cure thoroughly,
Let the mortar harden.

In this way, concrete sidewalk board 7 with accurate dimensions and shape can be manufactured extremely easily.

The concrete sidewalk board 7 constructed in this manner can be used by laying it on a sidewalk etc. in the same way as a general one. This will be briefly explained below.

Create a gravel base in the target area.

The predetermined area is dug down a little, gravel is poured into it, the gravel is compacted, and then sand for unevenness adjustment is placed on top of it. After this, roll it again to make the top surface flat.

The concrete sidewalk board 7 is laid on the gravel subsurface. Place other concrete sidewalk boards 7 on the side of the concrete sidewalk board 7 that was laid first.

In this way, the concrete sidewalk boards 7, 7... have the outer walls 2a, 2b separated by at least their lengths by the spacer pieces 3, 3... of the base frame bodies 1, 1..., and there is a gap between the spacer pieces 3, 3... Since it is open, this part becomes a water permeable gap. Therefore, concrete sidewalk board 7 using the above-mentioned sidewalk board base frame
When paving with this method, reliable water-permeable gaps are obtained on the paved road surface, resulting in a pavement with good water permeability.

That is, rainwater or the like falls onto the gravel subsurface through the gaps formed between the spacer pieces 3, 3, and further permeates underground through the gravel substratum.

It is also possible to fill the sidewalk board base frame with tiles of matching dimensions and lay them on the sidewalk.

The tiles are loaded into the base frame body 1, 1 of the sidewalk board base frame...
All you have to do is place it facing upwards and insert the tiles inside.

The installation procedure and the like are the same as those for installing the concrete sidewalk board 7 described above.
