DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cloth upholstery finish,
The present invention relates to a base material used for a wall surface, a ceiling, or the like for performing a paint finish.

[0002]

2. Description of the Related Art As interior finishing of a building, finishes such as wallpaper and vinyl cloth which are generally referred to as cloth upholstery and paint finishes by applying an appropriate coating are performed. . As a base material for these finishes, plywood such as veneer or gypsum board is used.The base material is cast on a wall surface or a ceiling surface with a nail or the like, and a cloth material is adhered to the surface or painted. And finish it.

[0003] In order to treat the outer corner or the inner corner of the wall surface, the base material is simply abutted or a corner material having an L-shaped end surface is stuck, and if necessary, the surface is smoothened with putty.
A cloth material is stuck on the upper surface. In addition, at the boundary between the ceiling surface and the wall surface, the boundary portion (surrounding edge portion) is a decorative finish with a watermark form. Conventionally, at a boundary portion of such a portion that is not formed on the same plane, each member is independently nailed or screwed to each wall surface or ceiling surface.

[0004] By the way, the relative position of the wall surface or the like in the building may be slightly shifted due to the shaking of the building when it receives a wind, the expansion and contraction of the structure (dry moisture absorption of wood, etc.), or the delicate change of the ground. For this reason, even in places where there was no problem at the time of finishing at the time of construction, fine wrinkles, floating and cracks were generated on the surface of the cloth over time. Of course, cracks also occurred on the painted surface.

More specifically, as shown in FIG. 3A, base plates 01 and 02 serving as bases of the cloth A are nailed to the respective rims C connected to the pillars B, and the cloth A is applied or painted. However, a gap 03 exists between the base plates 01 and 02, and the gap 03
Fluctuates, the wrinkles or lifts up at the corners 04 of the cloth A, and cracks occur in the case of painting.

[0008] As shown in FIG. 8A, a base plate 01 is nailed on the front and back sides of a stud D at an opening portion of a wall surface of a room without a frame, and a narrow base plate 05 is provided on an end surface. And a coating such as pasting a cloth A on the surface of the substrate. However, when the stud D shrinks due to drying, a step 06 occurs between the base plate 01 and the base plate 05 on the end face. For this reason, the cloth A is cracked or the painted surface is cracked.

Further, the work of assembling the base material is very complicated depending on the location of the assembling.
Of course, the above-mentioned outgoing corners and inset corners, but in the case of forming the watermark around the ceiling peripheral edge and the wall surface in the form of a watermark,
The base form for covering the steel frame portion projecting indoors is very complicated.

For example, the watermark gap between the ceiling surface and the wall surface must be formed uniformly, and since the work is performed upward, it is troublesome. In addition, the watermark wall surface must accurately form a watermark portion at regular intervals, and the dimensions of the watermark gap must be accurate. In particular, when a gypsum board is used as a base material, the end face where the gypsum is exposed is hard to be adhered with a cloth paste, and the cloth tension work itself is troublesome.

[0009] The covering of the steel frame portion projecting indoors is shown in FIG.
As shown in (a), a rafter F is incorporated around the steel frame E, and a narrow base plate 07 is nailed to the rafter F, which is complicated.

Various proposals have been made even before this to improve workability. For example, Japanese Patent Publication No. 53-280
Japanese Patent No. 51 discloses a gypsum board provided with a non-sticking portion of the base paper and the gypsum portion on the front and back sides. Has been proposed. However, gypsum board does not necessarily contribute to the improvement of workability because it requires reprocessing at the site, and the connection of non-coplanar surfaces of further processed gypsum board is performed only with the base paper of gypsum board. In addition, it cannot cope with the above-mentioned delicate shaking of the wall surface or the like, and does not prevent generation of wrinkles or cracks of the cloth stuck on the upper surface.

Japanese Patent Publication No. 4-81017 discloses a member for connecting a rigid plate, which is a main base material, to a base material at an inner corner and an outer corner with a plate-shaped object disposed at a corner. . However, the above-mentioned member lacks cooperation with a base material (gypsum board) used in places other than the inside and outside corners, and is a special member for general versatility, and cannot be said to be easy to use.

[0012] Further, as a problem of the base material, the size is generally standardized to a certain degree, and the height of the wall surface is generally insufficient, so that the upper and lower sides are added. For this reason, putty finishing of the upper and lower seams is required. Of course, if a base material with a sufficient height is used, handling is inconvenient, and if the width is made narrower to make it easier to handle, the joint between the adjacent base plates on the left and right increases, reducing work efficiency. Does not. In addition, even if a cut is made by leaving the protective paper on one side of the gypsum board so that the base material can simply be folded, if the cut portion is exposed, a putty finish is naturally required at the joint, and the cut In the case of the back surface, putty finishing is still necessary to eliminate wrinkles on the protective paper portion on the front surface, which is not a solution.

Accordingly, the present invention proposes a new base material which suppresses the occurrence of abnormalities on the finished cloth surface and painted surface and is excellent in workability.

[0014]

A base material such as a wall surface according to the present invention is formed by connecting a plurality of base plates with a thin sheet material having sufficient toughness and flexibility. Therefore, since the respective base plates can be arbitrarily bent with respect to each other, they can be nailed relatively to the non-coplanar surfaces, and the base plates which become non-coplanar after the nailing are connected by a thin sheet material. As a result, it becomes an integral structure, and does not cause any abnormality in the cloth attached to the location even when the building shakes. Of course, the nail attachment point of the base material is set as a place away from the connection point so that the shaking of the building does not directly act on the connection point. Further, the above-mentioned member is a single member as a whole, so that handling is easy and workability is excellent.

In particular, when a V-shaped valley in which the connecting side surface of the thin sheet material is formed as a valley bottom is formed between the end surfaces of the boundary portion of the connecting base material, it is easy to form an inner corner. Material.

Further, when the connected base plate is opened between the end surfaces of the boundary portions of the base materials to be connected, a slight gap is provided at the end surface portion on the thin sheet material connection side, and the other surface side end surface collides. When the base plate is formed in an inverted V-shaped valley shape, even if the length of the base plate is sufficiently long, the base plate can be folded at the thin sheet material portion and transported in a state where the width is reduced, so that the handling becomes easy. Also, when the base material is opened to make the same surface, one of the base plates rises slightly, and this lift is pressed against a wall surface by a nail, and the collision edge rotates around the center, and the thin sheet material is rotated. The portion is strongly stretched, and putty finishing is not required for the thin sheet material portion to be folded.

[0017] When an appropriate interval is provided between both ends of the base material to be connected, the base material can be easily formed with a watermark around the ceiling or a ceiling or a wall surface.
When the end face of the watermark is formed on the surface where the cloth material can be adhered, and the elongated plate body whose surface is the surface where the cloth material can be adhered is attached to the bottom surface of the watermark recess, it is used for the watermark surface where the cloth tension work is easy. Base material can be provided.

Further, if a bendable shape-retaining member is interposed between both end surfaces of the base material, the base material can easily form rounded corners.

If a thin, inconspicuous reference line is displayed on one or both sides of the front and back sides, it becomes a reference for nailing and cutting, and when a thin sheet material is provided on the entire surface of the base plate, the overall strength is increased. Can be

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention basically comprises a base plate 1 and a thin sheet material 2, and the base plate 1 is made of gypsum board, plywood or other plaster board. Gypsum board was used, but all could be replaced with plywood or other plasterboard. The gypsum board (base plate) 1 includes a front and back protection paper 11 and a gypsum portion 12 interposed and filled between the protection paper 11. Further, the thin sheet material 2 may be a paper-thin material such as a glass fiber-containing fabric, a non-woven fabric, or a synthetic resin sheet, as long as it has sufficient toughness and bendable flexibility. In particular, when a gypsum board is used, a thin sheet material may be used in place of the protective paper, or may be provided along the inner surface of the protective paper. Further, in each of the embodiments described below, the cloth finish is used as an example, but in all the embodiments, a paint finish may be used instead of the cloth finish.

<First Embodiment> In the first embodiment, the end surface 1 of the base plate 1 is in a state where the base plate 1 is in abutting condition and at a boundary portion.
3, a V-shaped valley a in which the thin sheet material 2 side is a valley bottom is formed.

FIGS. 1 to 4 show a first embodiment, in which two base materials 1a and 1b having an appropriate width and an appropriate length are abutted, and a V angle between the end surfaces 13 of the abutting portion is 90 degrees. A valley a is formed, and the protective paper 11 on the back of the V-shaped valley a is further formed.
A thin sheet material 2 is adhered to the base material and the two are integrally connected.

The reference line 3 is displayed on the front and back surfaces of the protection paper 11 and the front surface of the thin sheet material 2 or on a range of any one of them or a combination thereof. The reference line 3 is thin and inconspicuous. If the display is dark, it may be visually recognized through the cloth material A.

The above-mentioned base material is mainly used at the protruding corners and the corners, and as shown in FIGS. 3 (b) and 3 (c), the V-shaped valley a is bent to form an end face of each other. When the base material 13 is brought into contact, the base material is in a state where the base plates 1a and 1b are bent at 90 degrees, so that the base material is separated from the protruding corner and the entering corner at the trunk edge C and the stud D connected to the column B. If a nail is directly nailed to a location (the same applies to all the following embodiments), the bases at the inner corner and the outer corner are formed. In particular, in the above-mentioned nailing work, if the reference line 3 exists, it becomes a mark of a nailing point, which is convenient (in all the following embodiments,
A reference line is provided at an arbitrary position as needed, and the description thereof is omitted.) In addition, since the non-coplanar base plate 1 is connected by the thin sheet material 2, the base material has an integral structure, does not strongly act on the connecting portion even by shaking of the building or the like, and is thin even when some force is applied. No abnormality occurs in the cloths connected by the sheet material 2.

Further, depending on the material of the thin sheet material, if the effect of the screw becomes possible, screwing that cannot be used with the gypsum board becomes possible. In particular, when a thin sheet material is provided on the entire back surface of the base plate 1, the strength of the whole base material is increased, and the screwing range is also widened.

Also, since the whole can be folded in two, even if the member has a length corresponding to the vertical height of the wall surface, it is not particularly inconvenient to handle depending on the adjustment of the width. There is an advantage that the workability is improved by the amount that is not included, and it is also beautifully finished because there is no upper and lower replenishment points (the advantage of this long shape can be naturally adopted in all other embodiments, The description of this point will be omitted in the following embodiments.

Although the first embodiment shows an example in which the thin sheet material 2 is provided on one surface of the gypsum boat (base plate) 1, a modified example as shown in FIG. 4 can be adopted. For example, when manufacturing a gypsum boat, a base material 1A whose main part is shown in FIG.
, A non-woven fabric (thin sheet material) 2
a, or a thin plastic sheet (thin sheet material) 2b on the inner surface of the protective paper 11, as in a base material 1B whose main part is shown in FIG. Further, on the end face 13a of the gypsum part, a material for hardening gypsum is applied,
The end face 13a may be maintained in a robust state by mixing. These base materials 1A and 1B can be employed in all the following embodiments as well as the first embodiment. In the following embodiments, the thin sheet material 2 is formed in the protective paper 11. Is omitted.

FIGS. 5 and 6 show a second embodiment, in which the number of base plates 1 is three, and the left and right base plates 1c are connected by thin sheets 2 similarly to the first embodiment. The intermediate base plate 1d has a short width, and the inside angles of the V-shaped valleys b on both sides of the intermediate base plate 1d are 45 degrees. Note that the V-shaped valley b may be formed by inclining either one end surface or both end surfaces.

As shown in FIG. 6, when the bent portion is bent at the V-shaped valley b and employed at the protruding corner or the entering corner of the first embodiment, it can cope with the protruding or entering corner of the chamfered shape. .

FIGS. 7 and 8 show a third embodiment, which is a base material used for an opening without a frame on the wall surface in a room. The opening in which the frame is not provided in the room is to stick a cloth continuously so as to have a sense of unity with the wall surface, and the base material of the third embodiment used for this is the same as that of the second embodiment. Then, on both sides of the opening end surface base plate 1e, a wall surface base plate
And a V-shaped valley a having an inner angle of 90 degrees is formed on both sides of the opening end surface base plate 1e.

Therefore, since the width of the opening of the wall surface is determined to a certain extent, if the width of the base plate 1e for the opening end surface is determined in advance, the base material can be easily attached to the opening end surface continuously to the wall surface. 8 and the workability is improved.
Since the step 06, which is a conventional problem shown in (a), does not occur, wrinkles and cracks of the cloth material A and the painted surface do not occur after finishing.

Further, when the base plates of the first and third embodiments are used in combination, as shown in FIG.
The underlayer forming operation is significantly simplified. That is, for the wall surface, the base material for the corner in the first embodiment is adopted, the base plate 1a is nailed or bonded to the rafter F on the wall, and the other connected base plate 1b is The width of the protruding length of the columnar cover is set along the protruding side surface of the steel frame E, the end face base plate 1e of the third embodiment is set on the front surface of the steel frame E, and both side base plates 1f are provided.
Is glued to the upper surface of the base plate 1b with an adhesive or is connected and integrated at another appropriate first stage, so that no vertical F
The base material can be easily covered with the protruding steel frame E without incorporating the same.

<Second Embodiment> In the second embodiment, adjacent base plates 1 are connected to each other by a thin sheet material 2 with an appropriate space between adjacent base plates 1.

FIGS. 10 and 11 show a fourth embodiment of the present invention, which is a base material having a continuous ceiling and wall surface, which is used when the watermark E is used for the edge. That is, the ceiling base plate 1g and the wall base plate 1h are connected by the thin sheet material 2 with a predetermined interval c. The interval c is obtained by adding the width of the watermark G to the thickness of the base plate 1.

As shown in FIG. 11, the wall base plate 1h is fixed on the rim C and the stud D, the ceiling base plate 1g is fixed on the ceiling edge H, and the base plates 1g and 1h are fixed. The cloth A is stuck on the indoor side surface.

Therefore, as shown in FIG. 11, the width of the watermark G is naturally determined, its workability is remarkably improved, and the ceiling base plate 1g and the wall base plate 1h are connected by the thin sheet material 2. In the finished cloth, wrinkles and cracks are prevented from occurring, or problems such as peeling are prevented.

FIGS. 12 and 13 show a modification of the fourth embodiment, in which a long reinforcing plate 4 having an h-shaped cross section is incorporated. The long reinforcing plate 4 may be made of a resin material or an extruded aluminum material. The gap of the facing portion 41 is made to match the width of the gypsum portion 11 of the base plate 1g, and the non-facing portion 42 is a watermark G to be formed. In the production of the gypsum board, the gypsum board may be incorporated inside the protective paper 11, or attached to the edge of the gypsum board (base plate) 1g separately from the gypsum board (base plate) 1g. Later, 1h
And the thin sheet material 2.

Therefore, as illustrated in FIG. 13, since the tip of the non-opposing portion 42 of the long reinforcing plate 4 collides with the wall base plate 1h, the long reinforcing plate 4 acts as a ruler, and an accurate watermark G is formed. Very easy to assemble.

FIGS. 14 and 15 show a fifth embodiment of the present invention, which is a base material for a watermark wall surface or a watermark ceiling surface. In addition to the connection, the elongated plate 5 is attached to the sheet material 2 at the same interval d. In particular, when an existing gypsum boat is used, at least the end face of the base plate 1i is a protective paper 11i.
Use the part covered with a. In addition, slender plate 5
Is a thin plate having an appropriate strength, such as a plastic plate, a wooden plate, or an aluminum plate, and has a surface on which a cloth A can be attached by attaching paper.

In the base material, the formation interval of the watermark is adjusted by the width of the base plate 1i, and the watermark wall surface,
It is nailed to the ceiling face of the eyelet and used as a groundwork for the surface. Therefore, the watermark surface is accurately and easily formed,
Since the cloth A is easily adhered to the inside of the concave portion of the watermark by the elongated plate body 5 and the protective paper 11, the work efficiency of crossing the watermark surface is significantly improved.

FIGS. 16 and 17 show a sixth embodiment of the present invention.
j is provided with an interval e corresponding to the formation width of the rounded corner, is connected by the thin sheet material 2, and is provided with a shape retainer 6 that can be bent at the same interval e. The shape retainer 6 is formed of plywood or plastic in a shape in which a number of ridges 62 are bent on the base portion 61, and the base portion 61 is attached to the thin sheet material 2 and is interposed at the interval. Things.

Thus, when the base plate 1j is nailed to the protruding corner of the wall surface, the base plate 1j has appropriate durability against the pressure received from the outside by the ridges 62 as shown in FIG. The base plate 1j sandwiching the protruding corner portion is connected by the thin sheet material 2, so that the base plate 1j absorbs some expansion and contraction and finishes. There is no risk that a problem will later occur on the cloth surface.

Further, in place of the shape retainer 6, a shape retainer 6a made of a thin plate made of a foamed resin that can be formed into a compressed shape may be employed. As shown in FIG. 17 (b), when the base plate 1j is nailed to a protruding corner position of a wall surface, the inner shape side of the shape preserving body 6a is compressed, thereby retaining the rounded protruding corner.

<Third Embodiment> In the third embodiment, an inverted V-shaped valley is formed between the adjacent base plates 1 and can be folded and transported, and the connecting portion of the folded portion is connected to the wall surface of the base material or the like. When nailing or the like, it is possible to maintain a clean surface without any wrinkles, and as a result, it is possible to substantially adopt a long member.

FIGS. 18 and 19 show a seventh embodiment in which the base plates 1k and 1l are connected by thin sheet material 2 and are characterized by the shape of the end face between the base plates 1k. That is, when the connected base plates 1k and 1l are opened from the folded state to the single use state, the end face portion on the connecting side of the thin sheet material 2 has a slight gap f, and the other end face 14 collides. Formed in an inverted V-shaped valley shape. Of course, as long as the above conditions are satisfied, the end faces of the base plates 1k and 1l are not flat, but may be curved or stepped.

Therefore, even if the lengths of the base plates 1k and 1l are long enough to sufficiently satisfy the vertical height of the wall surface, they can be transported in a state where the thin sheet material 2 is folded and the width is reduced. Therefore, handling becomes easy.

When the base plates 1k and 1l are opened to form the same plane, one base plate 1k is replaced with the other base plate 1l.
However, the end surface 14 collides and becomes slightly lifted. Therefore, one of the base plates 1k is connected to the stud D
After the base plate 11 in the other floating state is pressed against the wall surface to suppress the floating, the collision edge 14 rotates around the center and the thin sheet material 2 is fixed. The part will be stretched strongly. Therefore, when the raised base plate 1l is held down and fixed to the wall with nails,
The folded portion of the sheet member 2 is fixed to a wall surface or the like in a state in which it is stretched neatly without becoming wrinkled.

Accordingly, it is possible to substantially employ a long member which is easy to handle, and it is not necessary to perform the work of adding the upper and lower walls of the base material, so that the putty finish of the seam is not required, and the work efficiency is reduced. Significantly improved. In addition, since the surface of the base material is applied with a predetermined tension to the sheet material, it also has an advantage that it can be finished to a beautiful surface.

The present invention is not limited to the first, second and third embodiments, but includes the number of base plates, the width and length of base plates, and the distance between base plates. The width, the angle of the V-shaped valley, and the like may be selected as required values. In addition, when combining three or more base plates in one base material, the connection form of each adjacent base plate is selectively combined with the first embodiment, the second embodiment, and the third embodiment, respectively. You may adopt it.
