Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a civil engineering and construction panel.

[0002]

2. Description of the Related Art Various types of civil engineering and construction panels, particularly panels attached to outer walls, have been marketed and used. Examples include natural stone panels, tiles, and spray material panels. These are applied to the surface of the building to beautify the appearance, and are called dry method for those applied and sprayed on site. The advantage is that the construction period is short,
It does not pollute the work environment at the site.

Panels are also laid on balconies of buildings and the like. This is to improve the feeling of walking, to prevent slippage, and for aesthetic reasons. Such applications include artificial turf, babyshoe type panels, wood panels and the like. Furthermore, in so-called outer trench construction, it is also applied to pouches, around trenches, gate posts, fences, and the like. In addition, since water slips or splashes in the garden, sidewalks, platforms, etc., water permeability is desired.

[0004]

However, the conventional ones have the following drawbacks. As an outer wall panel,
Natural stone panels are excellent but very expensive, tiles are cheap but quickly cracked, and spray panel has aesthetic problems.

In addition, tiles and the like have no water permeability, and cannot be used in the above-mentioned parts where water permeability is required.

Further, the aesthetic appearance of the spray material panel is a problem, and it is inevitably seen as inexpensive.

[0007]

In view of the above circumstances, the present inventor has completed the civil engineering and construction panel of the present invention as a result of diligent research, and its characteristic features are as follows.
An aggregate of 0.1 to 5.0 mm is mixed with a thermosetting resin, and the mixture is manufactured by heat compression molding and has water permeability,
The mixing ratio of the aggregate and the resin is 2 to 15 parts by weight of the resin with respect to 100 parts by weight of the aggregate.

The thermosetting resin does not have to be special and may be ordinary one. Examples thereof include epoxy resins, polyurethane resins, unsaturated polyesters, alkyd resins, etc., which may be commercially available.

Needless to say, the resin may be mixed with what should be usually mixed in addition to the aggregate. For example, pigments, fragrances, germicides and surfactants may be mixed. This is because mixing a surfactant improves water permeability. This amount is about 0.1 to 5 parts by weight with respect to 100 parts by weight of the aggregate. Below this, the effect is small, and above this, it is meaningless and not so good for the resin.

As the aggregate, any inorganic particles such as stones, ceramics and glass can be used. These aggregates are preferably aesthetically colored aggregates. Further, various colors may be mixed, or the patterns may be divided and cured. Further, by using a plurality of aggregate colors, granite or marble may be used.

The size of the aggregate is 0.1 to 5.0 mm. This means that most of the aggregates have this size, and it is not a strict matter such as no grains falling off.

To obtain the above-mentioned granite tone, for example, to obtain the black granite, black aggregate, white aggregate, pink (skin color,
Aggregate (gray, etc.) may be mixed under the following conditions. Black Aggregate: Size 2-3 mm, 20-30% White Aggregate: Size 2-3 mm, 30-40% Pink Aggregate: Size 1-2 mm, 20-40% In addition, in order to create a white shade, The following conditions are good. Black Aggregate: Size 2-3 mm, 10-20% White Aggregate: Size 2-3 mm, 50-60% Pink Aggregate: Size 1-2 mm, 20-40% Also, to give a red shade, The following conditions are good. Black aggregate: size 2-3 mm, 10-20% White aggregate: size 2-3 mm, 20-30% Pink aggregate: size 1-2 mm, 50-60%

In the case of stone aggregate, the mixing ratio of the aggregate and the resin is preferably about 2 to 15 parts by weight of the resin with respect to 100 parts by weight of the aggregate. This is to ensure water permeability. Naturally, the lower the specific gravity of the aggregate, the less the weight of stone is.

Although the thickness of the panel of the present invention is free in principle, it is about 3 to 20 mm, more preferably 5 to 10 mm. The size is completely free. From the viewpoint of ease of molding, which will be described later, 30 × 30 cm or 50 × 50 cm is convenient.

Next, the hot compression molding which is the most important point of the present invention will be described. The heat compression molding itself is a commonly used method for molding plastics and is an ordinary method in itself. However, there is no water-permeable type (very little resin) building member as in the present invention, and such a manufacturing method is completely new. This means that resin is originally used as a spraying material on the outer wall (compression molding etc. is not possible by spraying), and a plate is manufactured at the factory using the same resin with its extension line and stuck on site. Has been carried out.

In this method, a material in which a resin, an aggregate and the like are mixed is put in a mold and heated and compressed. For example, in the case of an epoxy resin, it is completed at about 140 ° C. in 10 to 20 minutes. At this time, if the mold is filled with a material that gives a natural stone tone, a very good looking product can be obtained. Compared to the conventional method of simply pouring and leaving, the surface is also completely different.

Further, by making various modifications on the surface of the die, so-called burner finish tone, Edo cutting, etc. can be freely formed.

The panel of the present invention can be laid as it is on a sidewalk, a veranda, a wall surface or the like, but it may be attached to a substrate. For example, it is attached to a well-drained plastic plate that drains well. Further, it may be used at any place regardless of where it is used.

Since the panel of the present invention itself has a very small amount of resin, the peripheral portion may be chipped (aggregate may drop) during handling. To prevent this, the resin content may be increased only in the peripheral portion. For example, such a portion having a width of about 5 to 20 mm on the periphery is used. The resin content is 15 parts by weight or more, preferably 20 parts by weight or more with respect to 100 parts by weight of the aggregate. There is no water permeability, but there is no problem because it is only the peripheral part.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a plan view showing an example of the panel 1 of the present invention. It used the following mixture as aggregate. The size is 300 × 300 × 10m
m. Black Aggregate: Size 2-3 mm, 30% White Aggregate: Size 2-3 mm, 35% Gray Aggregate: Size 1-2 mm, 35% Therefore, the appearance is similar to the black granite.

In this manufacturing method, the above-mentioned aggregate and resin (epoxy resin) are mixed, placed in a molding machine and compression molded. The mixing ratio of the aggregate and the resin was 8 parts by weight of the resin with respect to 100 parts by weight of the aggregate.

FIG. 2 is a partially enlarged perspective view of the end portion of the example of FIG. The amount of resin is very small, and the aggregates 2 are bonded to each other at almost all points.

FIG. 3 is a plan view showing another example of the panel 1 of the present invention. The aggregate is the same, but the peripheral part 3 and the central part 4
And the resin amount is different. In the peripheral portion 3, the amount of resin is 100
20 parts by weight were mixed.

In FIG. 4, a water-permeable plastic plate 5 is fixed to the back surface of the panel shown in FIG. The fixing method may be adhesion or any other method.

[0025]

The civil engineering and construction panels of the present invention have the following advantages. (1) As it has water permeability, it has a veranda, an outer groove, a pouch,
It can be laid on sidewalks, gardens, and various other places to create a safe floor that does not slip. (2) If the aggregate (plural color aggregates) is properly selected,
It gives the appearance of natural stone and is very aesthetically pleasing. (3) Since it is heat-compression-molded, it is easy to mold and can be thin but strong. (4) Various shapes can be made by devising a molding die.
Burner finishing can be easily performed by processing the surface of the mold.
