Abstract

PURPOSE:To permit wooden brick pavements to be constructed on a desired paving area by a method on which placing frames formed by pressing wooden bricks into a square plastic molded frame with partition walls to form holding sections are set connectedly. CONSTITUTION:In a square frame 1, 9-holding sections 2 are partitioned by walls 3 to form bottom plates 5 and hook pieces 4 are extended slantly downwards into the sections. In this case, the frame 1 and these component parts are formed integrally of plastics. Wooden bricks 11 are pressed into the sections 2 and the side tiered portions are fixed by the pieces 4, where sand 10 is bonded to the upsides of the walls 3. The placing frames are sec connectedly on a desired paving area to complete a wooden brick pavement. The appearance of the pavement can thus be raised due to no exposure of partition walls to the joints, and the water permeability of the joints can also be secured.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a footboard installation frame for holding footboards such as wooden bricks, concrete slabs, or various types of tiles.

[Prior Art] A laying frame for holding footboards was proposed by the present inventor.

This generally consists of a plurality of holding compartments in a frame body, and after holding steps such as wooden bricks in the holding compartments, the wooden bricks are laid in a predetermined area. This is to complete the pavement using treads such as
3301 etc.).

[Problems to be Solved by the Invention] As mentioned above, the conventional footboard laying frame proposed by the present inventor has a structure in which bricks and other footboards are held in each holding section, and the frame is laid flat. Paving with treads is completed by arranging them in series on the groundwork.

However, since the paved road surface obtained as described above is based on the footboards held in the holding section of the paving frame, the upper end of the partition wall of the holding section is slightly above the joint of the paved road surface. It is visible. This may be an eyesore for some people.

The present invention aims to solve the above-mentioned problems without causing other problems as side effects.

[Means for Solving the Problems] The gist of the present invention is to provide a frame with a plurality of holding compartments for holding footboards, and a water permeable opening in the lower part of each of the holding compartments. constructing an open bottom plate, and constituting a fixing means for fixing the footboards in the holding compartments, and further laying footboards with sand adhered to the upper part of the partition wall that partitions each of the holding compartments; It is a frame. It is appropriate that the holding compartment walls and all other constituent elements of the frame are made of elastic plastic material.

The planar shape of the frame is preferably square or rectangular for convenience of installation. However, circular and other shapes are also acceptable.

The planar shape of the holding compartments should naturally correspond to the shape of the steps to be held by them. Therefore, a rectangular shape is common, but a circular, oval, or triangular shape can also be adopted. Of course, if the holding sections are configured in a circular or elliptical shape when viewed from above, gaps will be created between each holding section, so measures such as installing a large number of pressure protrusions in these gaps may be taken. It becomes necessary.

Furthermore, various configurations can be freely adopted as the fixing means.

For example, it is possible to adopt a configuration in which the footboards are fixed from the bottom surface of the bottom plate with screws or the like.

Further, for example, elastic collar pieces may be extended diagonally downward inward from the partition walls that partition the holding partitions, thereby supporting the side portions of the footboards. When adopting this configuration, as will be described later, it is preferable to configure a step that expands downward in the middle of the side of the footboard. In this way, the lower end of the flange piece can be locked to the step on the side of the step board inserted into the holding compartment, and the flange piece can be reliably prevented from coming off. If the footboard is of a type like this brick that expands and contracts repeatedly depending on the moisture content, the pieces can also absorb the expansion and contraction.

By the way, the stepboards to be held in the above-mentioned holding section are, as described above, solid bricks, concrete slabs, tiles, etc., and are not limited to specific ones. Further, as described above, in either case, it is preferable that a step is formed in the middle of the side part so that the lower end of the collar piece can be fixed in the holding section. Further, the sand may be natural sand or may be produced by crushing suitable stones. If desired, sands of various colors can be used; it is suitable that the sands are attached using an adhesive.

Specifically, for example, the adhesive is applied to the upper part of the compartment wall by turning the installation frame upside down and dipping it slightly into an adhesive tank, and then keeping the installation frame upside down in the same way and flattening the top surface. By bringing the upper part of the laying frame into contact with the sand placed on the partition wall, the sand can be attached to the upper part of the partition wall. However, for partition walls that are common to the outer wall of the frame, it is best to immediately scrape off any sand that has adhered to the outer periphery of the partition wall. The purpose is to allow adjacent laying frames to come into good contact with each other during laying.

It goes without saying that the means for attaching sand to the upper part of the partition wall may be of any other configuration.

Incidentally, the outer wall of the frame body is provided with male and female connecting means for connecting adjacent ones.

[Function] Since the present invention has the above-described configuration, if the desired footboards are held in each holding section in the laying frame, and then the laying frame is successively installed in a desired area, Paving with treads without exposing the partition walls is completed. First, the stepboards mentioned above are charged and held in the holding section of the laying frame.
As mentioned above, if a collar piece is formed on the partition wall that divides the holding section, and a step that expands downward is formed in the middle of the side part of the step, the step and the like can be simply placed in the holding section. By simply pushing in, the relevant footboard can be fixed in the holding compartment. That is, when the steps are pushed into the holding section, the collar piece initially retreats outward to allow the pushing movement, and then when the step of the step passes the lower end of the collar piece,
The flange piece returns to its original position and locks onto the step. The treadle is thus secured within the holding compartment. Due to its elasticity, the above-mentioned flange pieces can be
It also has the effect of absorbing the expansion and contraction.

After the footboards are held in the holding sections of the laying frame in this way, the laying frame is laid in a required area. The laying frames are connected to each other by male and female connecting means formed on their outer walls. Note that it is appropriate to prepare a flat water-permeable base in advance in the above-mentioned required area. A gravel base is suitable as the permeable base. The above-mentioned gravel base can be created by, for example, digging the required area slightly, placing gravel there, compacting it, and applying sand to adjust the unevenness.

However, if a flat base for laying is prepared in advance in this manner, a flat paved road surface using footboards can be extremely easily constructed simply by arranging the laying frames in series as described above.

Moreover, in the road surface constructed in this way, sand is attached to the upper part of the partition wall that divides the holding sections, so sand appears at the joints of the paved road surface made by treads, and the partition wall is hidden. ing. Therefore, a natural texture can be obtained on the paved road surface.

The above-mentioned sand was attached to the top of the partition wall, and was not simply charged into the joints between the footboards, so it would not scatter from the joints and spread onto the road surface. Also, if you simply put sand into the joints, it will sink downward.
In order to hide a partition wall, it is necessary to fill it with a large amount of brick, but for example, if real bricks are used as footboards and a flange is constructed on the partition wall, it is not necessary to simply fill it as described above. In this case, the expansion and contraction of the actual bricks is inhibited by the sand, and the effect of the brim pieces is nullified. On the other hand, in the present invention, sand is attached to the upper part of the partition wall, and the area around the collar piece is not filled with sand, so its function is not inhibited.

In addition, since the adhesive is not completely filled between the sand grains, water permeability can also be ensured. Furthermore, the paved road surface constructed by such a paving frame is suitable for use as a sidewalk or a parking lot. [Example] An example of the present invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, nine holding sections 2, 2, .

The holding sections 2, 2... are respectively partition walls 3, 3...
from the upper end of the partition walls 3, 3, . . . , one flange piece 4 is made to project diagonally downward inward from the upper end of each holding partition 2, 2, .

Further, a bottom plate 5 is formed at the bottom of each of the holding sections 2, 2, . A circular water permeation hole 6 is bored in the central circular part. In addition, each holding section 2, 2・
The openings along each side of . . . become water permeable openings 7, 7, .

Furthermore, connection recesses 8, 8 are formed on two adjacent sides of the four sides of the frame l, and connection protrusions 9 are formed on the other two adjacent sides.

The frame l and each of the above-mentioned components constituting it are integrally molded from a resilient plastic material. Natural sand 10 is attached to the upper part of the partition walls 3, 3, . . . that partition the holding sections 2, 2, . To attach the sand 10, first, the laying frame is turned upside down and slightly dipped into an adhesive tank (not shown), so that the adhesive is attached to the upper part of the partition walls 3, 3, . . . . Subsequently, the sand 10 is attached by etching the upper parts of the partition walls 3, 3, .

Since this embodiment has the above-described configuration, it can be used for paving sidewalks, parking lots, etc. in the same way as the conventional wooden brick laying frame proposed by the inventor described above. can.

Here, real bricks 11, 11... are used as stepboards, and the wooden bricks 11, 1l... are approximately It is configured in a square shape, and there are steps 12, 12 and 12 on each side that expand at the lower side.
Configure... The heightwise positions of the steps 12, 12... are as follows when 1 liter of wooden bricks are charged into the holding section 2.

The charging and holding of the bricks 11, 11, . . . can be carried out by simply pushing the bricks 11, 11, . Then, since the collar pieces 4, 4, etc. retreat outward at this time, the charging of the wooden bricks 1l, 11, etc. is allowed, and the side steps l2, l2,... At the same time as passing the lower end position of the flange pieces 4, 4-..., the flange pieces 4, 4... return inward, and their lower ends meet the step l2.
, l2 . . . and leads to fixing the actual bricks 11, 1 . . . into the holding compartments 2, 2 . . .

On the other hand, the area that requires paving is prepared in advance on a base that is as flat as possible. Here, a gravel base L3 with good water permeability is used.
The gravel base 13 can be created by digging the area a little, adding gravel, compacting it, and then applying sand to adjust the unevenness. After doing so, place wooden bricks l1, 1 in the holding compartments 2, 2...
The above-mentioned laying frame charged with 1... is arranged in series on the above-mentioned gravel base 13. As shown in FIG.

In addition, since the sand 10 attached to the partition walls 3, 3, etc. is not completely filled with adhesive etc. between the sand grains, gaps remain between each sand grain, and water permeability is lost. It won't happen. [Effects of the Invention] According to the present invention, the partition walls of the holding section are not exposed at the joints of the paved road surface formed by the obtained treads, and the sand is visible, so that the appearance of the pavement formed by the treads is improved. .

There is also no risk of the sand particles visible from the joints scattering.

Furthermore, the sand that covers the partition wall at the joint will inhibit the absorption effect of the expansion and contraction of the wood brick by the brim piece, even if, for example, wooden bricks are used as the base of the footing and a brim piece is placed on the partition wall. It will not be done.

In addition, the constructed paved road surface can ensure water permeability at the joints.
