Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wooden block aggregate for paving roads, etc., and a paving method using the same. Road pavement in places such as, residential areas, etc.
This invention relates to a wooden block aggregate for laying on rooftops and other places, and a paving method using the same.

[Conventional technology]

There is a conventional method of paving using wooden blocks. That is, ■ Wooden block bodies 1 as shown in Fig. 8 are directly pasted one by one onto a mortar-finished surface of gravel compacted ground a as shown in Fig. 9 with adhesive C, and the wooden blocks are A method of filling the gaps in body 10 with joint material d.

■ Fit the wooden block body l into the plastic frame e as shown in Figure 10, and as shown in Figure 11, install the plastic frame e on the gravel compacted ground a or on the mortared surface, and screw Method of connecting construction while fixing with f.

etc.

[Problem to be solved by the invention]

However, the construction method of gluing the wooden block body 1 to a mortar-finished surface requires the skills of a professional engineer, is time-consuming, cannot be constructed in the rain, does not have sufficient adhesive strength, and is easily peeled off. There was a problem.

In addition, in the construction method in which the wooden blocks 1 are fitted and the plastic frames e are combined and connected to the gravel compacted ground a1 or mortar finished surface, it is difficult to connect the plastic frames e to each other, and the connecting claws are often damaged and become unworkable. Despite being a good product, the workability was surprisingly poor, and even after installation, it did not fit in well, and it did not feel good when stepped on, as it wobbled.

Also, the gaps between the plastic frames e and the wooden blocks 1
Earth and sand enters the gap between the plastic frame e and the wooden block body 1, which acts to suppress the pressure when the wooden block body 1 absorbs water and expands, and the buffer disappears, resulting in the overall springing up as a place for the expansion force to escape. It may happen.

Therefore, the technical problem of the present invention is to have excellent workability on site,
Moreover, it is an object of the present invention to provide a wooden block aggregate for paving roads, etc., which has excellent adhesion to the road surface.

[Means for solving the problem] The means for achieving the above problem is to paste a plurality of wooden blocks impregnated with synthetic resin on a bituminous board and make a board of wooden blocks. That's true.

In this wooden block assembly board, the wooden blocks are attached to the bituminous board preferably using a water-resistant adhesive.

When paving a road surface, etc., aggregates of these wooden blocks are laid on the road surface.

[Effect]

Since bituminous board is a mixture of wood and bituminous materials,
It has elasticity and is extremely water resistant. In addition, because it contains wood, it blends well with synthetic resin-treated wooden blocks and prevents the adhesive surface from peeling, unlike combinations of extremely dissimilar materials such as mortar and wooden blocks or plastic and wooden blocks. There aren't many.

This means that the bituminous board and the wooden block treated with synthetic resin are not completely different from each other, and that the adhesive has a strong effect on both, and that it does not repeatedly expand and contract. This is probably because the bituminous board and the wooden block treated with synthetic resin are similar to each other.

It is no exaggeration to say that the installation of bituminous boards and wooden blocks is simply laid flat on the ground.It is so simple that no special skills are required, and anyone can do it. Moreover, the construction finish is always uniform. Furthermore, there are no problems that would make the work difficult, and construction can be done at any time, regardless of the weather.

The combination of the appropriate elasticity of the bituminous board and the woody feel of the wooden block gives it a great feel when treading.

With the above means, the above problem can be solved.

〔Example〕

Hereinafter, the present invention will be specifically described with reference to Examples.

FIG. 1, FIG. 2, and FIG. 3 are a plan view, a front right view, and a rear view, respectively, showing a collection board of wooden block bodies 1 according to an embodiment of the present invention.

As shown in these figures, a plurality of wooden blocks 1 are bonded to a bituminous board 2 by an adhesive layer 3, and a joint material 4 is pasted between the wooden blocks 1.

In this embodiment, the aggregate board of the wooden block body 1 has a size of 10
0 x 10 (] x 37 mm wooden block 1 5 x 5
One unit board is 1/4 m' with 25 pieces pasted.

On the other hand, a 10 mm thick bituminous board 2 made of 70% by weight of bituminous material such as coal tar and 30% by weight of wood such as chips was
Cut into 90x49[1s], make drainage holes 5 with a diameter of 6 mm at the locations corresponding to the four corners of the wooden block body 1, and place a joint board 4 made of a foamed rubber board with a thickness of 3 mm on this surface.
Total dimensions 100 x 100 x pasted on two side surfaces
Twenty-five pieces of 37 mm joint-pasted wooden block bodies 1 with 20 tongue pieces 2a of bituminous plates 2 protruded from two sides are crimped using a synthetic rubber-based solvent-type fast-drying adhesive such as silicone rubber.

As a result of the test, after crimping the bituminous board 2 and the wooden block body 1,
After approximately 1 hour had passed, there was no abnormality at all after 6 months of immediate immersion in water, and no peeling occurred unless intentional destructive peeling was performed.

In addition, the dimensions, shape, and attachment of the wooden block body 1 are determined by the number of pieces,
It goes without saying that the area and shape of a unit board can be changed as appropriate depending on the object, but the product value can be further improved by forming small paragraphs or chamfering on the upper end of the block board. can be made into something.

The bituminous board 2 is preferably a plate with a bituminous content of 70% by weight or more, but a similar bituminous fiberboard with a bituminous content of about 35% can also be used. If so, you can also use this.

The bituminous board 2 and the wooden block body 1 can be bonded using adhesives, nails, screws, etc., but it is preferable to use adhesives such as polyurethane, epoxy, or phenolic synthetic resins. , synthetic rubber-based water-resistant adhesives are preferably used.

As a drainage measure for the wooden block body 1 collection board, bituminous board 2
Approximately 611I are placed directly under the four corners of the wooden block body 1.
In addition to providing a drain hole 5 with a diameter of about I11,
) is a front view of the main part in Fig. 3, and (b) is a side view of the same), a drainage groove is formed in the part of the tongue piece 2a of the bituminous board 2 that corresponds to the gap in the wooden block body 1, and It is preferable that the interlocking portions of the collecting disks have a gap of about 10 spaces.

The wooden block aggregate thus manufactured is laid on a road surface, ie, a gravel compacted surface, a mortar finished surface, or an asphalt finished surface.

Fig. 5 shows the case of construction on crushed stone, in which a sand plate 1 is laid on crushed stone 10 which has been subjected to compaction treatment as shown in (a), and an asphalt emulsion 12 is poured on top of the sand plate 1. Gluing. This is a construction method suitable for cases where there is a risk that wooden block aggregates may float due to poor drainage. Fifth
Figures 1 and 2) show a method of driving a pile 13 up to the compacted surface of crushed stone 11 and fixing it in a screw hole 2C provided at a corner of a tongue piece 2a of a bituminous plate 2 with a nail, screw 14, or the like.

Figures 6 and 7 show the case where wooden blocks (8) are laid on 15 concrete surfaces and 16 asphalt surfaces, respectively.
Fixed by When using the adhesive 17 in these cases, it is desirable to use a water-resistant adhesive such as epoxy, chloroprene rubber, or asphalt.

In addition, in places where water permeation to the ground is required, a practical number of permeation holes are provided in the mortar or asphalt finishing layer, and conversely, in construction such as rooftops where water leakage prevention is required, water permeation through the mortar or asphalt layer is required. No holes are provided.

In addition, by using foamed rubber material as the joint material 4 between the wooden block bodies 1, it prevents dirt from entering, buffers the expansion pressure, and eliminates overall bulges and jumps.
Provides a paved road surface with a comfortable walking feel.

〔Effect of the invention〕

As explained above, the present invention provides the following effects.

■ On-site construction is extremely simple, workability is good, and the finished state is always uniform with no defects.

■ There is no peeling, lifting, or overall swelling or jumping after construction.

■ It does not have the hardness of asphalt or concrete pavement, and has a gentle feel when stepped on, providing a pleasant walking sensation and relieving fatigue.
