Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building member, and more particularly to a decorative thin plate used as a building member such as a stainless steel plate and an FRP plate, and a method for producing the same. .

[0002]

2. Description of the Related Art For example, a column standing upright in the entrance hall of a building is made of reinforced concrete as a structure for maintaining the strength of the building. The outer surface of concrete is covered. In this case, normally, a semi-cylindrical stainless plate obtained by bisecting a cylinder in the longitudinal direction is manufactured and used in combination.

Conventionally, when the stainless steel plate 2 is used as the decorative plate as described above, the stainless steel plate 2 is machined.
Was plastically deformed, and the inner surface was subjected to spot welding or the like for reinforcement of the iron plate 12 or the like. In this case, since the entire surface of the stainless plate 2 is not in close contact with the iron plate 12, the stainless plate 2 itself needs to have rigidity.
A stainless plate 2 having a thickness of about 5 mm is used. If the steel plate is welded to the stainless steel plate 2 having a thickness of about 1.5 mm to reinforce it, the outer surface of the pillar will not be deformed even when the user leans on or pushes the pillar when using the building. When the iron plate 12 is spot-welded to the stainless steel plate 2, welding marks are generated on the outer surface of the stainless steel plate 2. In order to erase it, the outer surface of the stainless plate 2 is polished and finished. Iron plate 12 welded to the inside of stainless plate 2
Is directly welded to the reinforcing bar when the stainless plate 2 is attached to the reinforced concrete column structure.

In addition, for example, when manufacturing a pool having a cave or a waterfall, there is a case where an artificial rock whose surface is made of FRP (reinforced plastic) is used. Artificial rocks can be freely colored, and are indistinguishable from real rocks in appearance. Manufacture of artificial rock is performed by making a mold from plaster, synthetic rubber or the like based on natural rock, and pouring FRP in which polyester and reinforcing fibers are mixed in a molten state into the mold to solidify. Then, if the inside is hollow, it will dent if pushed during use, so at the installation site, construction work such as filling sand or pouring concrete and hardening it was done.

[0005]

However, it is necessary to accurately plastically deform the stainless steel plate 2 into a semi-cylindrical shape.
Even by mechanical processing such as pressing, it cannot be processed by a single pressing, and it is performed by repeatedly performing the pressing processing in steps of several mm. Therefore, it takes a lot of time and costs a lot. In addition, it takes time and effort to remove the traces of the welding of the iron plate 12 to the stainless steel plate 2 from the outer surface of the stainless steel plate 2 to finish a clean outer surface, resulting in extra cost. In addition, since a steel plate is welded to a 1.5 mm stainless steel plate and has a large weight, in the case of a long pillar, it has been unavoidable to separately manufacture and combine them. In addition, when tapping a stainless steel cylinder when using a building, a metallic sound of hollow contents may give the user the impression that the building is a cheap building.

In addition, the conventional method of manufacturing artificial rock by FRP or the like requires work at the installation site and it is necessary to pour concrete into the entire interior of the artificial rock. It was up. Moreover, the construction period was extended because work at the installation site was required. In addition, a cavity is easily formed between the packed concrete and the FRP forming the outer surface, and a dent portion may be formed when pushed during use.

[0007]

In order to achieve this object, the concrete reinforcing thin plate of the present invention is a thin plate having a planar shape.
Were fixed by modeled after the mold having a curved surface, the glass fiber reinforced concrete is applied directly on one side all <br/> surface of the thin, since it is produced by solidifying the glass fiber reinforced concrete, glass It is reinforced with fiber reinforced concrete.

Further, in the concrete reinforcing thin plate of the present invention, a flat thin plate is fixed by following a curved mold.
Straight glass fiber reinforced concrete at one side total surface of the sheet
Since it is produced by coating by contact and solidifying the glass fiber reinforced concrete, it is reinforced by the glass fiber reinforced concrete, and the mounting member for fixing the concrete reinforced thin plate to a building is the glass. The surface to which the fiber reinforced concrete is applied is fixed by the glass fiber reinforced concrete.

[0009]

The concrete reinforcing thin plate of the present invention having the above structure is elastically deformed by placing a stainless plate or the like having a thickness of about 0.5 mm on an outer frame having an arbitrary diameter, and in that state, glass is sprayed inside. It is produced by spraying and solidifying fiber reinforced concrete. Increasing the amount of glass fiber added increases the adhesive strength of the glass fiber reinforced concrete to the stainless steel plate.

At this time, after the glass fiber reinforced concrete is sprayed, an iron plate, a rod or the like is solidified while being inserted into the glass plate reinforced concrete having both ends thereof sprayed inside the stainless steel plate. An attachment member for fixing the concrete reinforced thin plate to a building is fixed to the surface coated with the glass fiber reinforced concrete with the glass fiber reinforced concrete.

Further, an FRP which is cast into a mold and molded
5-10mm of glass fiber reinforced concrete inside
Artificial rock can be produced by spraying and solidifying by a spray method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 are process diagrams illustrating a method for producing a concrete-reinforced thin plate of the present invention. As shown in FIG. 1, the stainless steel plate 2 is cut into a predetermined size, and a bent portion 2 is formed on one end side for combining with another stainless steel plate.
a is supplied in a pressed state. The stainless steel plate 2 has a thickness of 0.5 mm, and at least the surface constituting the outer surface of the column is polished. The outer frame 1 is a mold made of gypsum having a semicylindrical recess 1a on the upper surface. The outer frame 1 may be made of a welded structure such as an iron plate, urethane rubber, foam polystyrene, FRP, or a wooden outer frame. As a simple means, it is possible to use cardboard for the outer frame. The recess is semi-cylindrical with a diameter of 600 mm.

When the stainless steel plate 2 is placed on the outer frame 1, the shape of the stainless steel plate 2 follows the recess 1a of the outer frame 1 due to its own weight, and the shape is as shown in FIG. Here, when the diameter of the semi-cylindrical column is small, it is necessary to apply a strong external force to forcibly elastically deform the stainless steel plate. In this case, the stainless plate 1 may be fixed with a vise 7 or the like as shown in FIG. Next, the baffle plate 9 is put on the end of the stainless plate 2 opposite to the bent part 2a. This is because the glass fiber reinforced concrete 3 is not applied to a predetermined end of the stainless steel plate 2 so that the glass fiber reinforced concrete 3 does not get in the way when it is superposed on another concrete reinforced thin plate 10.

Next, as shown in FIG. 3, mortar and glass fibers are directly sprayed on the inside of the stainless plate 1 by the direct spray method. Generally, the glass fiber for concrete reinforcement is formed by roving, which is obtained by gathering about 30 strands of approximately 200 fibers having a diameter of 10 to 20 μm, or chopped strands obtained by cutting the strand to a length of 6 to 25 mm. It is used according to the method. Here, the product name "JSR Tomac Super" manufactured by Japan Latex Processing Co., Ltd. is used. Mortar is a mixture of normal cement, sand and water.

The glass fiber is supplied to the roving cutter 6 as a long roving. The mortar is supplied to the mortar pump 5 in a state where the cement, sand and water are well stirred by a mixer or the like. The compressor 4 generates high-pressure air, and the air blown from the compressor 4 and speeded up is supplied to the mortar gun. The mortar gun 11 is supplied with glass fibers cut into a length of about 6 to 25 mm by a roving cutter 6 and mortar by a mortar pump 5. The glass fiber and the mortar are mixed in the mortar gun 11 by the air having a high speed and sprayed onto the stainless plate 2. As shown in FIG. 3, the glass fiber reinforced concrete 3 in which glass fibers and mortar are mixed is 5 to 10 mm on the stainless steel plate 2.
It is composed of a certain thickness. After that, the baffle plate 9 is removed.

Since the glass fiber reinforced concrete 3 has a high viscosity, the thickness does not change greatly even if it is left to solidify as it is. It takes about 14 days for the glass fiber reinforced concrete 3 to completely solidify, but the vise 7 can be removed early. There is concern about the deformation of the stainless steel plate 2 due to the dimensional change when the glass fiber reinforced concrete 3 is solidified, but it can be kept within a practical range by increasing the sand cement ratio or increasing the fiber amount. is there. This is because the glass fibers restrain the dimensional change by increasing the glass fibers. Thus, the concrete reinforcing thin plate 10 as shown in FIG.
Is produced.

Further, as shown in FIG. 5, both ends are put into the glass fiber reinforced concrete 3 immediately after the mounting plate 8 for mounting the stainless plate 2 is sprayed on the reinforced concrete which is a structure. If solidified, the attachment plate 8 can be attached to the stainless steel plate 2 without trouble. When the glass fiber reinforced concrete 3 is solidified, it strongly fixes the mounting plate 8. The mounting plate 8 is welded to the reinforcing bar protruding outside the reinforced concrete column. As a result, the concrete reinforcing thin plate 10 is fixed to the building.

In this embodiment, glass fiber reinforced concrete 3
Was used because the glass fiber reinforced concrete 3 is used to reduce the amount of concrete for reinforcement and to reduce the weight as a whole, and because the adhesion between the glass fiber reinforced concrete 3 and the metal plate is good. Is. In this embodiment, the spray method is used for coating, but a premix method may be used in which mortar is mixed and dispersed with chipped stride in advance. Further, the glass fiber reinforced concrete 3 may be sprayed by a spray suction method and then dehydrated under reduced pressure.

In this embodiment, a stainless plate is used, but an aluminum plate may be used. In the present embodiment, the production of columns reinforced with glass fiber reinforced concrete has been described, but it goes without saying that it can be used for production of inner wall members and outer wall members having a curved shape.

The method for producing artificial rock is almost the same as in the above embodiment. That is, a mold is made from natural rock with urethane rubber or the like, and molten FRP is poured and solidified. Next, the glass fiber reinforced concrete 3 is sprayed and solidified inside the FRP by a spray method. The thickness of the glass fiber reinforced concrete 3 at this time is 5 to 10 m.
About m is sufficient. The artificial rock produced by this method does not dent even if it has cavities inside, and has sufficient strength. Further, since the glass fiber reinforced concrete 3 is used to provide strength with a small amount of concrete, the weight of the artificial rock produced can be light and convenient for transportation. By reinforcing the glass fiber reinforced concrete 3 inside the FRP, not only artificial rock but also decorative reliefs, pillars, three-dimensional signs, monuments and the like can be manufactured.

Further, by forming the outer frame with FRP or a stainless plate and reinforcing the inner side with the glass fiber reinforced concrete 3, it is possible to easily manufacture a lightweight yacht, boat or the like. Further, as a roof waterproofing material, a waterproof material can be formed by a simple method by pulling a vinyl plate or the like downward and spraying the glass fiber reinforced concrete 3 thereon. It can also be used for repairing bathrooms and leaks. Also, when the lid of the drainage pit is made of glass fiber reinforced concrete, the drainage pit lid is easy to carry and install by drying the iron angle etc. on the back with part of it inside. it can.

[0022]

The concrete reinforced thin plate of the present invention has a curved surface.
Produced by applying glass fiber reinforced concrete over the entire surface of one side of a thin plate that is fixed according to the shape of the mold and is elastically deformed, and solidifying the glass fiber reinforced concrete, and reinforced with glass fiber reinforced concrete Since it has any curved surface , it is reinforced with glass fiber
It is possible to produce a decorative metal plate used for the outer surface of a concrete-reinforced column or the like with a small number of steps and at a low cost. Further, since the glass fiber reinforced concrete 3 is in close contact with the entire surface of the stainless steel plate, a sound that the contents are clogged is produced when hitting, so that the user does not have a cheap image.

Further, in the artificial rock, since the inside of the FRP is reinforced with glass fiber reinforced concrete, it is not necessary to fill the inside with sand or concrete after the installation, and the construction work can be completed in a short period of time. it can. Also, FR
Since the entire surface of P is reinforced with glass fiber reinforced concrete, it will not dent even if the outer surface is pressed.

Further, since the concrete-reinforced thin plate of the present invention is produced by applying glass fiber-reinforced concrete over the entire one surface of the elastically deformed thin plate and solidifying the glass-fiber-reinforced concrete, In addition to being reinforced with fiber reinforced concrete,
Since the attachment member for fixing the concrete-reinforced thin plate to the building is fixed by the glass fiber-reinforced concrete to the surface coated with the glass fiber-reinforced concrete, it is lightweight and convenient to carry.
No need for another process such as bolting the mounting member
Can be installed .
