Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a sheet tensioning method that is effective when applied to constructing a wall or ceiling surface using a sheet.

"Prior Art" Sheet ceilings, in which the ceiling surface of a room is made up of sheets, have been known for some time now. This is shown in Figure 15,
A sheet b is provided with a hook-shaped locking edge a along its entire circumference, and a surrounding edge d is fixed to the ceiling height of a wall surface C.
It is fixed with enough tension applied to prevent it from loosening or wrinkling.

By the way, in the above case, since the hook-shaped locking edge a is required at the peripheral edge of the seat b, the cost of the seat b becomes high, and the lower surface of the surrounding edge d is exposed indoors, which is not desirable in terms of design. There were cases where there was none.

In particular, in recent years, it has been considered to configure walls using the same method as the sheet ceiling described above, but in that case, the surrounding edge d is exposed around the wall, making it more noticeable than in the case of a ceiling, and therefore It was difficult to apply a notebook ceiling like the one above directly to a wall surface.

From the above, without providing the locking edge a on the seat b, and without exposing the surrounding edge d into the room,
It is desired to provide a means by which the sheet b can be stretched against a ceiling or wall, and for this reason, the use of the apparatus shown in FIGS. 16 and 17 is being considered.

The device shown in these figures was provided as a device to be used when fixing a wall hanging to a wall surface (Japanese Patent Laid-Open No. 52
-81918), as shown in FIG. The upper edge of the wall hanging f is fixed to the member e by wrapping a ruler g therein and pushing the ruler g into the groove formed in the member e.

Since it is difficult to apply sufficient tension to the wall hanging f only by using the above member e, the 17th
As shown in the figure, another member j having a rotatable lever i is attached to a position close to the floor, and the locking edge provided at the lower end of the wall hanging is engaged with the tip of the lever i. By stopping the lever i and rotating the lever i downward, tension is applied to the wall hanging r.

If the sheet is fixed and stretched using such a device, the members e and j corresponding to the above-mentioned surrounding edge d will not be exposed inside the room, which will solve the design problem. Can be done.

``Problems to be Solved by the Invention'' However, in the above-mentioned device shown in FIGS. 16 and 17, two types of members esj must be prepared, and in particular, a lever i for applying tension must be prepared. The member j has a complicated structure and shape and is expensive, and although the sheet does not require a locking edge on the side that is fixed to the member e, there is a locking edge on the side that is fixed to the member j. The drawback remains that an edge k is required. In addition, when fixing the sheet to the member e, the ruler g tends to shift or slide relative to the sheet, and sometimes even comes off, so it is not easy to fix the sheet, and it is not suitable for sheet ceilings or sheet walls. It is not necessarily effective when doing so.

"Means for Solving the Problems" The sheet tensioning method of the present invention involves wrapping a band-like sheet fixing jig around the peripheral edge of the sheet that forms the wall or ceiling surface of the room. When fixing the sheet to the circumferential edge by pushing the fixing jig into the groove formed on the side edge of the circumferential edge, temporarily adhere the sheet fixing jig to the surface of the circumferential edge. Then, the peripheral edge of the sheet is adhered to the surface of the temporarily adhered sheet fixing jig, and then the sheet fixing jig is peeled off from the surrounding edge and the peripheral edge of the sheet is folded back to attach the sheet fixing jig. After that, while pulling the sheet, the sheet fixing jig is reversed and pushed into the groove of the surrounding edge.

"Example" Hereinafter, an example in which a sheet wall is constructed by the method of the present invention will be described with reference to FIGS. 1 to 1O.

First, with reference to FIGS. 1 and 2, the surrounding edge 11 and the sheet fixing jig 2 for fixing the sheet S to the surrounding edge 1 used in the method of this embodiment will be described.

The surrounding edge 1 shown in FIG. 1 is a long member made of synthetic resin or aluminum profile, and has a structure in which a front plate 4 and a back plate 5 are connected to each other by a reinforcing plate 6.6, and its thickness The dimensions, that is, the mutual spacing between the front plate 4 and the back plate 5 are:
- It becomes gradually narrower from the side edge side (the left side in FIG. 1) to the other side edge side (the right side in FIG. 1).

A tongue portion 7 extends obliquely from one side edge of the back plate 5 toward the front plate 4 side, and a tongue portion 7 extends inward from one side edge of the front plate 4 in parallel to the tongue portion 7. Tongue 8
is extending. A groove 9 having a U-shaped cross section and opening toward the surface plate 4 is formed by these tongues 7 and 8 over the entire length at one side edge of the circumferential edge l. In addition, in other side camphor parts of this surrounding edge l,
A groove 11 having a substantially U-shaped cross section and opening toward the side is formed by the reinforcing plate 10 .

Further, a large number of streaks are formed on the surfaces of the front plate 4 and the back plate 5, respectively, so that both of these surfaces are rough.

Next, the sheet fixing jig 2 (hereinafter simply referred to as the jig) shown in Fig. 2 is formed of acrylic resin into a long and thin strip shape, and extends from both sides to the center in the width direction. A large number of cuts 12 are alternately made at predetermined intervals. This jig 2 is made of acrylic resin and has notches! 2... is inserted, so that it can be elastically twisted and deformed, and can also be elastically bent laterally.

Furthermore, double-sided adhesive tapes are attached to both the front and back surfaces of the jig 2, and release paper that can be freely peeled off during use is attached to the surfaces of these double-sided adhesive tapes. Note that the width dimension of this jig 2 is
The depth dimension of the groove 9 is slightly larger than that of the groove 9.

Next, a procedure for tensioning the sheet S using the circumferential edge 1 and the jig 2 described above will be explained with reference to FIGS. 3 to 10.

(i) First, as shown in Figure 3, there are four surrounding edges!・・・

The back plate 5 is brought into close contact with the wall base I5 so that t9... is on the outside, and each surrounding edge l...
Cut the ends of . at an angle of 45° to the length direction, and butt the ends together with a gap of a predetermined size (for example, about 51 mm).

Note that these surrounding edges 1... can be fixed to the wall base 15 by screwing, nailing, tacking, or gluing, but it is necessary to ensure sufficient fixing strength. pay attention to. In addition, if necessary, non-combustible material such as rock wool is attached to the inside of the surrounding edge l...

(ii) Next, prepare four jigs 2... each slightly longer than each of the surrounding edges l... fixed above, and attach both ends of them to 45mm in the same way as the surrounding edges 1... Cut into °. Then, move those jigs 2... around the edges as shown in Figure 4! With the direction of the inclination of the end of jig 2 and the direction of inclination of the end of jig 2 being opposite, peel off the release paper on the back side of jig 2 and attach it to both sides. Temporarily bond them onto the surface plates 4 of the surrounding edges l... using adhesive tape.

At this time, both ends of each jig 2... are positioned on the outermost side of the circumferential edge l... and overlapped with each other, and the center part of each jig 2... is positioned as shown in Fig. 3. curve inward. FIG. 5 is a sectional view of the central part of the jig 2.

(iii) Next, each jig 2 temporarily bonded above...
The release paper on the front side of the sheet is peeled off, and the back side of the peripheral edge of the sheet S is adhered to the entire circumference of the front side as shown in FIG.

(iv) Next, as shown in Fig. 7, one of the four jigs 2... is peeled off from the surrounding edge 1 along with the sheet S, and at the same time, the edge of the sheet S is folded inward. The jig 2 is rolled up in a curved state, and the sheet S is also adhered to the back side of the jig 2.

At this time, since the surface plate 4 of the circumferential edge l has streaks and has a rough surface, the adhesive force when temporarily bonding the jig 2 to the circumferential edge 1 is not very strong, so the jig 2 can be easily peeled off.

(V) Then, hold the jig 2 wrapped around the sheet S,
While pulling the sheet S outward, the jig 2 is turned over as shown in FIG. 8, and the jig 2 is pushed into the groove 9 over its entire length as shown in FIG. At this time, since the jig 2 can be twisted and deformed, by partially twisting the jig 2 while pulling the sheet S and sequentially inverting it from one end side to the other end, the entire length can be easily can be pushed into the groove 9.

(vi) By sequentially performing the operations (iv) and (v) above for all the surrounding edges l... Fixed and tensioned. FIG. 1O shows the state of a part of the corner after the jig 2 has been pushed into the groove 9. In addition, four jigs 2
... may be fixed in any order, but it is better to fix in the order of the upper jig, one side jig, the other side jig, and the lower jig in Fig. 3. .

In the above, one sheet S was stretched, but if the wall surface is wide, it is sufficient to stretch multiple sheets S... in succession. In that case, the surrounding edge I is shown in Fig. 11. All they have to do is to line them up like this and fix them to the wall base 15. In addition, for the large corners of the room, as shown in FIG. 12, after installing the sheet S on one wall base 15a in the above procedure,
The sheet S may be fixed by attaching the surrounding edge 1 to the other wall base 15b. Alternatively, as shown in Fig. 13, the surrounding edges 1.1 are attached in advance to the wall bases 15a and 15b with the grooves 9 and 9 facing each other, and the sheets S and 2 are fixed around them U+ and t. Alternatively, as shown in FIG.
It is also possible to use two connected corner edges 20. By doing this, in either case, only a small gap is left between the tensioned saws 1-9 and 2.

As explained above, according to the method of this embodiment, the jigs 2 are wrapped around the entire circumference of the sheet S, and the jigs 2 are reversed to wrap around the edges l...
Since the sheet S is fixed by being pushed into the groove 9 of It is hidden inside and is not exposed indoors.

According to this method, after temporarily adhering the jig 2 to the circumferential edge l and adhering the circumferential edge of the sheet S to the surface of the jig 2, the jig 2 is peeled off from the circumferential edge l to remove the sheet S. By folding it back, the jig 2 is rolled in, and by twisting and inverting the jig 2, and pushing it into the groove 9, it is fixed.
At the same time as the sheet S is fixed, the sheet S is automatically pulled outward, and sufficient tension can be applied. Since the sheet S is folded back and bonded to both sides of the jig 2, the jig 2 will not slip or shift relative to the sheet S when the jig 2 is turned over.
The fixing work of the sheet S can be easily performed, and the sheet S can be reliably pulled.

Furthermore, when temporarily bonding the jig 2 to the surrounding edge l, the center part of the jig 2 is curved inward, and the sheet S is rolled up and bonded in the curved state.
The central portion of the sheet S is pulled outward to a greater extent than the peripheral portion, and therefore, a large tension can be applied to the central portion of the sheet S, which is particularly prone to loosening and wrinkles.

Although the present invention has been described in detail above, the present invention is not limited to the above. For example, in the above example, 4
With both book jigs 2... in a curved state,
..., but it is not always necessary to do so, and it is also possible to position each jig 2 ... on the inside of the surrounding edge 1 ... and temporarily glue it in a straight line. Or, of the two jigs 2 and 3 facing each other, the one to be fixed to the circumferential edge l first is temporarily glued in a straight line without being curved, and the one to be fixed later is It is also possible to curve only the jig 2.

Further, although the jig 2 used in the above embodiment is made of acrylic resin, it is not necessarily limited to this, and may be made of other materials as long as it has appropriate flexibility and flexibility. A jig may also be used.

Further, instead of using double-sided adhesive tape, an adhesive may be applied to both the front and back surfaces of the jig 2, and release paper may be attached to the jig 2.

Furthermore, the shape of the tightening is not limited to the above, but may be changed as appropriate as long as it has a groove into which the jig wound around the sheet is pushed.

Although the above embodiment is an example in which a wall surface is constructed of sheets, it is of course possible to construct a sheet ceiling in exactly the same manner.

"Effects of the Invention" As explained in detail above, according to the present invention, after temporarily adhering a jig to the surrounding edge and adhering the peripheral edge of the notebook to the surface of the jig, the jig is peeled off. The sheet is folded back to wrap around the jig, and the jig is then inverted and pushed into the groove to fix the sheet, eliminating the need for a locking edge on the sheet, which is required in the case of conventional sheet ceilings. The seat can be manufactured at a low cost, and it is advantageous in terms of design because the surrounding edges are hidden behind the seat and are not exposed inside the room.At the same time, the seat is automatically pulled outward when it is fixed, so it has sufficient tension. This has the effect that the sheet can be stretched in a state where it has been applied.
