DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint decorative structure of a building board and a joint decorative member used for the same, which are arranged in parallel with their side edges facing each other at a predetermined interval with respect to a base. .

[0002]

2. Description of the Related Art As a style of interior or exterior of a building, it has recently been proposed to attach an architectural board having a decorative layer on the surface thereof to the surface of a foundation. A building board is generally composed of a rectangular base layer and a decorative layer applied to the surface of the base layer.When such a building board is used as an interior or exterior of a building, it has a fireproof property. In addition, it is desirable to have excellent heat insulation properties, but it is also desirable to have excellent workability in addition to them.

[0003]

A typical example of an architectural board which itself is excellent in fire resistance and heat insulating properties is an architectural board in which the base layer is made of gypsum and the decorative layer is made of plaster. . Thus, when such building boards are arranged and used side by side (butting each other) with substantially no gap therebetween, the boundaries of the building boards, ie, joints, are exposed as they are. Since there is no
The requirements for fire protection and thermal insulation can satisfy this. However, it is extremely difficult, if not impossible, to arrange the side edges of the building boards adjacent to each other neatly and orderly with almost no gap due to various factors such as the accuracy of the foundation of the building itself. Poor workability.

[0004] On the other hand, when the above-mentioned building boards are arranged in parallel with their side edges facing each other with an appropriate gap therebetween, the workability is excellent,
Since the joints are exposed as they are, in the event of a fire, there is a high possibility that wood, which is a common base material, will spread from the joints, resulting in poor fire protection. Furthermore, since the joints are exposed as they are, the heat insulating layer is partially absent between the building boards, so that the heat insulating property is deteriorated and the appearance is deteriorated.

[0005] The present invention has been made based on the above facts, and an object of the present invention is to provide a joint board decorative structure for a building board and a joint joint used therein, which are excellent in fire protection, heat insulation and workability. It is to provide a decorative member.

According to one aspect of the present invention, each side edge of a base is opposed to each other at a predetermined interval along a joint of building boards arranged in parallel. A joint decorative member is inserted, and the joint decorative member includes a core formed of a bundle of inorganic fibrous materials, and a decorative sheet member covering an outer peripheral surface of the core. You.

[0007] In the above invention, since the building boards are arranged side by side with the respective side edges facing the base at a predetermined interval, they are arranged side by side. There is no need to arrange the side edges neatly without gaps, and therefore excellent workability is ensured. Furthermore, since the joints of the building board are not exposed as they are due to the joint decorative member being inserted along the joints of the building board, excellent heat insulating properties are obtained, and in the event of a fire, In addition, there is no possibility that wood, which is a general base material, spreads directly from the joints, and the fire resistance is improved. Further, even if there is a slight step between the surfaces of the building boards, the effect is obtained that the joint decorative member does not become noticeable. Furthermore, since the joint decorative member inserted along the joint is composed of a core made of a bundle of inorganic fibrous materials and a decorative sheet member covering the outer peripheral surface of the core, the joint itself is hardly burned, and therefore, is excellent. Fire protection is ensured. Further, since the core is composed of a bundle of inorganic fibrous materials, the joint decorative member has a suitable flexibility for insertion along the joint of the building board, and therefore, the joint of the joint decorative member. The work of inserting into the device is extremely easy, and the workability in this aspect is also excellent.

[0008] According to another aspect of the present invention, a joint decoration is inserted along the joints of the building boards arranged in parallel with the side edges facing each other at a predetermined interval with respect to the base. There is provided a joint decorative member comprising a core made of a bundle of inorganic fibrous materials, and a decorative sheet member covering an outer peripheral surface of the core.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a joint decorative structure of the present invention and a joint decorative member used therein will be described in further detail with reference to the accompanying drawings.

FIG. 1 and FIG. 2 show a part of the interior of a building provided with a preferred embodiment of the joint makeup structure of the present invention. A pair of architectural boards 4 are fixed on a base 2 of the building (see FIG. 2). The base material constituting the base 2 is made of wood in this embodiment. The pair of architectural boards 4 are arranged in parallel with one side edge 6 facing each other at a predetermined interval. The joint decorative members 8 described later are inserted along joints of the pair of building boards 4 arranged in parallel. Architectural board 4
Are covered by a baseboard 10 and the top edge surface is covered by a peripheral edge 12.
The baseboard 10 and the peripheral edge 12 are fixed to required parts by ordinary carpentry work.

Each of the pair of building boards 4 includes a rectangular base layer 14 and a decorative layer 16 provided on the surface of the base layer 14. The base layer 14 in each of the building boards 4 is a plaster board, a calcium silicate board, a foamed cement, which is a material excellent in fireproof and heat insulating properties among appropriate materials widely used as a base material in a building. It can be formed from a board or a volcanic glassy laminate. In the building board 4 shown in FIG. 2, a base layer 14 made of a commercially available gypsum board is used.
The base layer 14 has a core 18 formed by kneading and shaping a small amount of inorganic fine aggregate and water into a hemihydrate gypsum as a raw material.
And cardboard 20 covering both front and back surfaces and both side surfaces (left and right side surfaces in FIG. 2) of the core 18. The upper end surface and the lower end surface of the core 18 are exposed without being covered with the cardboard 20. The decorative layer 16 is formed from a solidified curable composition. Makeup layer 16
Can be conveniently formed by laminating a kneaded product of the curable composition and water on the surface of the base layer 14 in an appropriate manner, then curing and solidifying.

The kneaded material which is dried and solidified to form the decorative layer 16 can be formed by kneading the curable composition and water. The curable composition used for forming the kneaded material is advantageously an inorganic curable composition which is solidified by drying. Inorganic curable compositions preferably used include those obtained by adding appropriate additives to curable compounds such as calcium hydroxide, calcium sulfate, and magnesium oxide, particularly, plastered slaked lime, plaster, and water such as dolomite plaster. Curable compositions containing calcium oxide as a main component, in particular, those obtained by adding an aqueous emulsion to calcium hydroxide can be used. Further, if necessary, short fibers, inorganic fine aggregates, fine particles, thickeners, fluidizers, defoamers and the like can be added. Makeup layer 16
May be formed by attaching a not-shown decorative sheet member to the surface of the cardboard 20 in place of the above configuration.
The decorative sheet member can be formed by performing an appropriate printing process on a sheet member made of resin-impregnated paper, Japanese paper, olefin, soft polyvinyl chloride, or the like. In the building board 4 shown in FIG. 2, a decorative layer 16 made of stucco is shown.

The fixing of each of the building boards 4 to the base 2 of the building can be accomplished in a known manner, such as by gluing or nailing. When the nail is fixed by nailing, the nail has a fragile portion formed at a position near the head near the head, the diameter being smaller than that of the other main body. Nails (not shown)
It is preferred to use This nail is a thin nail of about 1.2 mm, and is driven from the surface of the building board 4 with a rubber spacer attached between the head and the fragile portion. The driving is stopped when the fragile portion of the nail substantially matches the surface of the building board 4. The operation of stopping the driving is easy due to the presence of the spacer. Next, by hitting the spacer and the head projecting upward from the surface of the building board 4 with a hammer in a direction perpendicular to the axis of the nail, the nail can be easily broken from the fragile portion. The broken part of the nail is located at a position substantially the same as or slightly submerged with the surface of the building board 4 and is exposed on the surface side of the building board 4. It can be said that the top is not visible.

The predetermined distance between the side edges 6 of the building board 4 is determined by fixing each of the building boards 4 to the base 2.
It is easily set by interposing a plurality of spacers (not shown) between the opposing side edges 6. Each of the spacers can be formed from a rectangular parallelepiped wood or an appropriate synthetic resin. Each of the spacers also has a building board 4
Are fixed to the base 2 and then extracted.

In the joint makeup structure of the present invention, as clearly shown in FIG. 2, the joint makeup member 8 is inserted along the joint of the pair of building boards 4 (in this embodiment, press-fitted). The joints of the pair of building boards 4 are made up. Referring to FIG. 3 as well, joint decorative member 8 includes a core 22 made of a bundle of inorganic fibrous materials, and a decorative sheet member 24 covering the outer peripheral surface of core 22. The core 22 is formed by bundling a plurality of inorganic fiber materials, each of which is relatively short. The inorganic fibrous material can be formed, for example, from glass wool. Decorative sheet member 2
No. 4 can be formed by performing an appropriate printing process on a sheet member made of resin-impregnated paper, Japanese paper, olefin, soft polyvinyl chloride, or the like. Core 22 and decorative sheet member 24
Has a substantially circular cross section and a diameter slightly larger than a predetermined distance between the side edges 6. In some embodiments, the joint decorative member 8 has a substantially elliptical cross section. In this case, the diameter (the maximum diameter or the minimum diameter) is formed to be slightly larger than a predetermined interval between the side edges 6. Note that the circular or elliptical shape is
It is not necessary to have a strict shape in a geometric sense, and it is sufficient if the shape is substantially such.

First, each of the building boards 4 configured as described above is arranged in parallel with the side edges 6 facing each other at a predetermined interval with respect to the base 2, and is fixed by bonding. . The predetermined distance between the side edges 6 can be easily set by using the spacer as described above.
Therefore, at the time of construction, it is not necessary to arrange the side edges 6 of the adjacent building boards 4 without any gaps, and excellent workability is ensured. Next, the joint decorative member 8 is inserted (press-fitted) along the joints, that is, between the side edges 6 of the building board 4. Thereby, the joint decorative member 8 is held at the joint of the building board 4, and the joint decorative structure is formed. The construction of the joint is completed only by performing the operation of inserting the joint makeup member 8 along the joint, so that the construction is extremely easy. In the joint makeup structure, the joint makeup member 8 is also provided.
Since the joints are not exposed as they are due to the presence of, excellent heat insulating properties can be obtained, and in the event of a fire,
There is no longer a possibility that the wood forming the fire spreads directly from the joints, and the fire resistance is improved.

Joint decorative member 8 inserted along joint
Is composed of a core 22 made of a bundle of inorganic fibrous materials (in the embodiment, an inorganic fibrous material made of glass wool), and a decorative sheet member 24 covering the outer peripheral surface of the core 22, so that it is difficult to burn itself, and therefore is excellent Fire protection is ensured. Needless to say, heat insulation is also ensured as desired. In addition, the joint decorative member 8 has a suitable flexibility for insertion along the joint, since the core 22 is composed of a bundle of inorganic fibrous materials, in this embodiment, a bundle of inorganic fibrous materials made of glass wool. Therefore, the work of inserting the joint decorative member 8 into the joint is extremely easy, and the workability in this aspect is also excellent. Since the core 22 is formed by bundling a plurality of inorganic fibrous materials, each one of which is relatively short, in the embodiment, glass wool, the flexibility is practically easily and reliably obtained. Since the joint decorative member 8 has a circular cross section and a diameter slightly larger than a predetermined interval between the side edges 6, the press-fitting operation is very easy, and the joint does not slip out of the joint. Is easily obtained. If the cross section of the joint decorative member 8 has an elliptical shape and the minimum diameter is slightly larger than a predetermined interval between the side edges 6, the minimum diameter portion is pressed into the joint. Let me know. This use form is useful, for example, when the thickness of the building board 4 is relatively thick (joint depth is relatively deep) and the joint width is relatively narrow. If the joint decoration member 8 has an elliptical cross section and its maximum diameter is slightly larger than a predetermined distance between the side edges 6, the maximum diameter portion is press-fitted into the joint. Let me know. This use form is useful, for example, when the thickness of the building board 4 is relatively thin (the joint depth is relatively shallow) and the joint width is relatively wide.

Next, another preferred embodiment of the joint makeup structure of the present invention will be described with reference to FIGS. 4 to 6, substantially the same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof will be omitted. As is clearly shown in FIG. 6, the joint decorative member 8 is integrally attached (adhered) so as to extend linearly in the longitudinal direction along one surface of the strip-shaped thin plate member 30. The thin plate member 30 can be formed of a wood material such as wood, plywood, or a medium-density fiberboard; paper; or a synthetic resin such as polypropylene or polyvinyl chloride, which is a relatively thin and hard material. The thin plate member 30 has a width larger than the width (diameter in the above embodiment) of the joint decorative member 8. The joint makeup member 8 is
The thin plate member 30 is positioned so as to project in the width direction from both sides of the joint decorative member 8. In this embodiment, the joint decorative member 8 is positioned at the center of the thin plate member 30 in the width direction. One of the protruding portions 32 of the thin plate member 30 from both sides of the joint decorative member 8 is connected to the lower surface along the side edge 6 of one of the building boards 4 (the left building board 4 in FIGS. 4 and 5) and the groundwork. 2 and the other of the protrusions 34
Is inserted between the lower surface and the lower surface along the side edge 6 of the other building board 4 (the building board 4 on the right side in FIGS. 4 and 5).

The joint makeup structure shown in FIGS. 4 and 5 is configured as follows. The one side of the building board 4 is first fixed to the base 2 as described above. Next, the projecting portion 32 on one side of the thin plate member 30 on which the joint decorative member 8 is integrally attached is forcibly inserted between the lower surface along the one side edge 6 of the building board 4 and the base 2. (Inserted). When the one of the building boards 4 is fixed to the base 2 by bonding, the protrusion 32 of the thin plate member 30 can be forcibly inserted relatively easily immediately thereafter. Further, even when the building board 4 is fixed with nails, the lower surface along the one side edge 6 of the building board 4 and the base 2 are not completely in close contact with each other, and there is some gap between them. Due to the presence, a forced insertion as described above can accomplish this relatively easily. By inserting the protruding portion 32 of the thin plate member 30 between the lower surface along the one side edge 6 of the building board 4 and the base 2, the joint decorative member 8 integrally attached to the thin plate member 30 becomes A part of the outer peripheral surface is held in a state of being pressed against, in contact with, or close to the one side edge 6. Next, the lower surface of the other side of the building board 4 along the side edge 6 is projected to the other side of the thin plate member 30.
Is fixed so as to cover the upper surface of the substrate 2. The joint decorative member 8 is positioned at each joint of the building board 4 in a state of being pressed, in contact with, or in close proximity to each side edge 6 of the building board 4 to make up the joint.

In the above embodiment in which the joint decorative member 8 is integrally mounted on one surface of the thin plate member 30, the joint decorative member 8 is firmly attached to each joint of the building board 4 while the construction is relatively easy. Can be installed. Further, since the joint decorative member 8 is firmly held without being pressed between the side edges 6 of the building board 4, there is no problem even if the accuracy of the interval between the side edges 6 is relatively rough. In this respect, it can be said that the workability is excellent. Other functions and effects are the same as those described with reference to FIGS.
