Description

  The present invention relates to a sheet structure.

  A sheet structure in which a sheet is stretched horizontally or substantially horizontally is known. The sheet structure is used, for example, as a ceiling of a building. When a sheet structure is used as a ceiling, it is extremely lighter than gypsum board, etc., which is generally used as a ceiling material. Because it has characteristics such as light transmission and the like, it is different from a general conventional ceiling.

By the way, the material of the sheet constituting the sheet structure used for the ceiling is required to have flame retardancy from the viewpoint of disaster prevention. In general, a film made of a flame-retardant resin (for example, a fluororesin film) or a film material in which a flame-retardant resin is coated on a substrate made of fiber (for example, a fluororesin coating film) Material) is used as a sheet constituting the sheet structure.
However, for reasons of cost, a sheet such as a film made of a non-flammable resin such as a vinyl chloride resin which is inexpensive may be used as a sheet constituting the sheet structure.
However, it is generally difficult to use such a sheet as a sheet structure, for example, when it is used for a ceiling where flame retardancy is required.

  It is an object of the present invention to provide a technique that allows a sheet having no flame retardancy to be used for a sheet structure as a sheet constituting the sheet structure.

In order to solve the above-mentioned problem, the present inventor proposes the following invention.
The invention of the present application is intended to be used as a set of at least two sheets in a state where they are fixed to the frame with a gap therebetween so as to face each other, and the first sheet, which is a sheet therebetween, and the first sheet This is a long fixing material that is capable of extending the second sheet, which is a highly flame-retardant sheet, substantially horizontally.
In addition, both of the at least two fixing members include, below the first fixing member, first fixing means used to fix one side of the first sheet and a side facing the first sheet, and the two fixing members. Both of the members are provided with second fixing means used for fixing one side of the second sheet and the side opposite to the second sheet above the first fixing means, respectively. One side of the first sheet and its opposite side are fixed to each of the first fixing means, and one side of the second sheet and the opposite side thereof are respectively fixed to each of the second fixing means of the two fixing members. , So that the second sheet is located at a predetermined height above the first sheet between at least two fixing members, so that the first sheet and the second sheet Overhang So that the resulting sheet structure has.
When this fixing material is used, the second sheet and the first sheet are arranged between the two long fixing materials in a substantially parallel state from above. In particular, when a sheet structure including the first sheet and the second sheet is used for a ceiling, a person usually sees the first sheet having no flame retardancy located on the lower side. This allows a person to see the first sheet, which is often aesthetically pleasing, for example. On the other hand, the second sheet, which has a relatively high flame retardancy (preferably, has flame retardancy) stretched over the first sheet, ensures the flame retardancy of the sheet structure.
Note that the term “sheet” in the first sheet and the second sheet in the present application refers to a film typically made of resin alone, a woven or knitted fabric woven or knitted with fibers, A sheet material such as a film material typically having at least one surface coated with a resin or rubber on at least one side of the base material being a woven or knitted fabric, or a sheet composed of a plurality of layers of resin or the like is not particularly limited. Used in the sense of including.
One side of the first sheet and the second sheet and the side opposite thereto are often straight in many cases, and the first sheet and the second sheet are often rectangular.

The fixing member of the present invention includes the first fixing means and the second fixing means as described above. The first fixing means may fix the first sheet by itself, or may fix the first sheet together with another member. The second fixing means may fix the second sheet by itself, or may fix the second sheet together with another member. The fixing member of the present invention may include, as the second fixing means, a plate-like body that is substantially horizontal (or horizontal) when the fixing member is used, over the entire length direction. In this case, the second sheet is formed by piercing one side and the vicinity of the opposite side of the second sheet with the plate-like body with a driving material such as a screw, so that the one side and the opposite side are at least two fixing members. May be fixed to the second fixing means.
When the fixing member has a plate-like body, an upper plate member extending vertically upward may be provided on an outer edge of the plate-like body. Note that, in the present application, the concept of the inside and outside of the fixing material is defined as a side closer to the other fixing material of the two fixing materials as an inside and a side far from the other fixing material as an outside.
The fixing material needs to be fixed to the building such as pillars, beams, ceilings, walls, etc. of the building, but if the fixing material has an upper plate, the outer surface of the upper plate is attached to the inner surface of the building, for example, the wall By driving a nail, screw or the like into the skeleton with the upper plate material penetrating from the inside in the attached state, the fixing material can be easily fixed to the skeleton.

The first fixing means may be present at various places in the fixing material. On the other hand, the first fixing means may extend over the entire length of the fixing material in the length direction. In addition, the fixing member may have the same cross-sectional shape when cut perpendicular to the length direction over the entire length in the length direction. If the cross-sectional shape of the fixing material cut perpendicular to its length direction is the same in all parts in its length direction, it is easy to manufacture the fixing material by extrusion molding. Become. The fact that the first fixing means is present over the entire length in the length direction of the fixing material is such that the cross-sectional shape of the fixing material when cut perpendicular to the length direction is the same in all parts in the length direction. It is suitable for
The first fixing means may be provided, for example, below the plate-like body. When the first fixing means is provided below the plate-like body, the lower part of the plate-like body and the inside of the plate-like body with respect to the first fixing means extend over the entire length of the plate-like body. A lower plate member extending below the plate-like body is provided, and one side of the first sheet, which is in contact with the lower end of the lower plate member and bent upward, and the opposite side thereof are fixed by the first fixing means. It may be fixed. The first sheet is located lower than the second sheet as described above. By providing the lower plate as described above, the position of the lower end of the lower plate can be the height of the upper surface of the first sheet, which is convenient for positioning the height of the first sheet. Since the first sheet is preferably horizontal as a whole, mainly from an aesthetic point of view, the height of the lower end of the lower plate of one fixing member should be constant, and the two fixing members should be fixed. The height of the lower end of the lower plate should also be constant.
The first fixing means in the fixing member having a plate-like body, wherein the first fixing means is located below the plate-like body and is opened downward; A fixed body that can be fixed to one side of the sheet or an opposite side thereof and that can be inserted into the opening, and that extends over the entire length of the plate-shaped body. In this case, inside the opening, a stopper for preventing the fixed body from dropping out of the opening while preventing insertion of the fixed body into the opening is provided. May be. According to such a first fixing means, one side of the first sheet or the opposite side thereof can be easily fixed over the entire length in the length direction of the fixing member, and one side of the first sheet or At the same time as fixing the opposing sides to the two fixing members, it is possible to apply a certain amount of tension to the first sheet in the width direction of the two fixing members. This is suitable for improving the appearance of the sheet structure, particularly the first sheet of the sheet structural material.
To further enhance the aesthetics of the seat structure, the first fixing means, for example, a long lower surface that is substantially flush with the lower surface of the first sheet for concealing the opening, After the fixing of one side of the first sheet or the opposing side thereof is completed, the fixing material is provided with a decorative material that can be fixed to the fixing material by hiding the first fixing means. preferable.

The present inventor also proposes the following components as one embodiment of the present invention. Such a component constitutes the above-mentioned fixing material in the case where the present invention includes the first fixing means and the lower plate, and the first fixing means and the lower plate are made into one member. Things.
In this case, the remaining part of the fixing member is a plate-like body or a plate-like body and an upper plate material integrated. In this case, the plate-shaped body may be a simple long plate, and the one in which the plate-shaped body and the upper plate material are integrated may be a long L-shaped member.
As described above, by dividing the fixing material into the part and the rest thereof, especially the remaining part, there are many general-purpose products, so that the range of selection can be expanded, and the width of the positioning of the above-described part with respect to the rest is expanded. .
The parts of the anchoring material and the rest thereof are both long, so that in all of their lengths the cross-section perpendicular to their length can be made identical, By doing so, its production by, for example, extrusion molding becomes easy.

The present inventor also proposes the following sheet structure as one embodiment of the present invention. The following sheet structure has the above-described operation and effect achieved by each fixing member by adopting the same configuration as the fixing member described above.
One example of the sheet structure of the present application is a state in which a first sheet, which is a sheet, and a second sheet, which is a flame-retardant sheet than the first sheet, are arranged in parallel to each other with a space therebetween. A long fixing material that is to be used in a pair of at least two pieces, and between which the first sheet and the second sheet can be stretched substantially horizontally. Both of the fixing members are provided below the first fixing means used to fix one side of the first sheet and the side opposite to the first sheet, and the two fixing members are both Above the first fixing means, there is provided a second fixing means used to fix one side of the second sheet and a side opposite to the second sheet, and the first fixing means comprises two first fixing members. The first means One side of the sheet and the opposite side thereof are fixed, and one side of the second sheet and the opposite side thereof are fixed to each of the second fixing means of the two fixing members, thereby fixing the two sides. The first sheet and the second sheet can be stretched so that the second sheet is located at a predetermined height above the first sheet between the materials. Between the two fixing members, and the two fixing members, so that the second sheet is located at a predetermined height above the first sheet, so that the first sheet and the second sheet It is a sheet structure stretched over two sheets.

The seat structure is, for example, a ceiling.
When the first sheet is a film made of a single resin, the material is, for example, vinyl chloride resin (PVC), polyethylene resin (PE), polypropylene resin (PP), ethylene vinyl acetate resin (EVA) , Polyurethane resin (PU), polystyrene resin (PS), acrylonitrile-butadiene-styrene copolymer resin (ABS), nylon resin (PA), acrylic resin (PMMA), polycarbonate resin (PC), methylpentene resin (TPX) And the like. For example, a film made of PVC, one of the above-mentioned resins, does not have flame retardancy, but even such a vinyl chloride resin film has higher flame retardancy, preferably flame retardancy. By combining the second sheet with the first sheet, the sheet can be used as the first sheet in the sheet structure of the present application.
The first sheet may also be, for example, a woven or knitted fabric woven or knitted with natural fibers or synthetic fibers, and at least one surface of the woven or knitted fabric substrate may be made of resin. In some cases, the material coated with the above is a typical film material. In such a case, the above-described resin can be used as the resin for coating the base material.
In addition, the first sheet may be formed of a resin or the like in a multi-layered form, but among the resins constituting the layer formed of the resin, those described above can be used.
The second sheet has higher flame retardancy than the first sheet. Preferably, the second sheet has flame retardancy. The second sheet is, for example, a glass cloth. As another example, the second sheet may be a carbon cloth made of carbon fiber, a fluorine fiber cloth made of fluorine fiber, a fluororesin film, or the like.

The inventor of the present application also proposes a construction method of the following sheet structure as one embodiment of the present invention. The following construction method of the sheet structure adopts the same configuration as that of the above-described fixing member, thereby achieving the above-described operation and effect of each fixing member.
One example of the method for constructing the sheet structure of the present application is to use a pair of at least two sheets in a state in which they are fixed to the frame with a space therebetween and arranged in parallel, and the first sheet, and the It is a long fixing material that is capable of extending the second sheet, which is more flame-retardant than one sheet, substantially horizontally, and the two fixing materials are both below the first fixing material. A first fixing means is used for fixing one side of the sheet and a side opposite to the one side, and the two fixing members are both above the first fixing means, and the second sheet is And a second fixing means used to fix each side opposite to the one side, and when at least two are fixed to the skeleton, at least two of the fixing members are fixed. That of the first fixing means Fixing the one side of the first sheet and the opposite side thereof to each other, and fixing the one side of the second sheet and the opposite side thereof to each of the second fixing means of the two fixing members. By executing, the first sheet and the second sheet are stretched so that the second sheet is located at a predetermined height above the first sheet between the two fixing members. This is the construction method for passing the sheet structure.
Before this construction method, a step of fixing the above-mentioned two fixing members to the frame in parallel with a gap therebetween may be included.

In the method for constructing a sheet structure according to the present application, the fixing member has a plate-like shape whose upper surface is brought into contact with a mounting surface that is a downward surface of the skeleton over the entire length thereof. Is used as the second fixing means, and the plate-like body and one side of the second sheet and the vicinity of the opposite side are pierced together, and the lower side of the frame is The plate-shaped body is attached to the mounting surface of the skeleton by driving a driving material into a surface, and one side of the second sheet and the opposite side thereof are attached to the second fixing means of the two fixing members. It may be fixed.
The upper surface of the plate-shaped second fixing means is brought into contact with the lower surface of a beam or a ceiling, for example, and the fixing material is fixed to the frame by driving a driving material such as a nail or a screw, and the driving material is used. By fixing the second sheet in this manner, it is possible to reduce the labor for fixing the second sheet.
The method for constructing a sheet structure according to the present application may further comprise: a driving member driven into a fixing member fixing one side of the second sheet; and a fixing member fixing the side opposite to one side of the second sheet. The method may further include a step of stretching the striated body between the inserted struts and allowing the striated body to support the second sheet from below.
When the second sheet is fixed to the fixing member using a driving material, it is difficult to apply tension to the second sheet. If the above-described striated body is used to support the second sheet from below, it is possible to prevent the second sheet from bending downward without applying tension. In addition, even if the striated body is fixed to the driving material by irreversible fixing using an adhesive or the like, the striated body is wrapped around the driving material and the two members are fixed by the frictional force between them. However, it may not be fixed. The latter has a smaller work load and is still sufficient to obtain the above-mentioned effects.
When viewed in a plan view, the striated body is stretched zigzag between the driving members so that a plurality of diamonds continuous at the apex are continuously drawn between the two fixing members. At the same time, an angle formed by the two striated bodies in a portion of the rhombus that comes into contact with the fixing material may be 33.4 ° or less. As described above, the downward bending and dropping of the second sheet can be prevented by supporting the second sheet with the striated body. Deflection may occur. In order to prevent such a risk, it is effective to reduce the distance between the striatum by stretching the striatum as described above.
In addition, as a striated body, any fishing line, piano wire, or any other thread-shaped material can be used.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of the fixing member 100 used in this embodiment. Two fixing members 100 in this embodiment are used as one set. The fixing member 100 in this embodiment is used for forming a sheet structure including a first sheet and a second sheet described below. The seat structure in this embodiment is, but not limited to, a ceiling of a building.
The fixing member 100 shown in FIG. 1 is a cross section of one of the fixing members 100 used as a pair. The other fixing member 100 has a configuration in which the fixing member 100 shown in FIG. The terms “inside” and “outside” used to describe the configuration of the fixing member 100 shown in FIG. 1 are based on the definitions already described, but the right side in FIG. 1 is inside the fixing member 100 and the left side is This corresponds to the outside of the fixing member 100.

The fixing member 100 includes an upper member 110, a lower member 120, a locking member 130, and a decorative material 140.
In this embodiment, the upper member 110, the lower member 120, the locking member 130, and the decorative material 140 are all made of resin, although not necessarily limited thereto.
The upper member 110, the lower member 120, the locking member 130, and the decorative material 140 are all long, and in this embodiment, their lengths are substantially the same.
Also, the upper member 110, the lower member 120, the locking member 130, and the decorative material 140 are not necessarily limited to this, but in this embodiment, in all the portions in the length direction, the cross sections perpendicular to the length direction are provided. Are identical. The upper member 110, the lower member 120, the locking member 130, and the decorative material 140 having such a shape are all easily manufactured by extrusion.

The upper member 110 includes a plate-like body 111 that is horizontal, at least substantially horizontal, when used. The plate-like body 111 is an elongated rectangle in plan view. The upper surface and the lower surface of the plate-like body 111 are flat in this embodiment.
The upper member 110 includes an upper plate member 112 extending upward from an outer edge of the plate member 111. The upper plate 112 is a plate perpendicular to the plate 111, and in this embodiment, the shape when viewed from the outside in FIG. 1 is a rectangle. As will be described later, the outer surface of the upper plate member 112 is brought into contact with the inner surface of a skeleton, for example, a wall when the upper member 110 is used.

The lower member 120 is attached to the lower side of the upper member 110 when the fixing member 100 is used.
The lower member 120 includes a horizontal plate 121. The horizontal plate 121 is a plate that is at least substantially horizontal when the fixing member 100 is used, and at least the upper surface thereof is flat. When attaching the lower member 120 to the lower side of the upper member 110, the upper surface of the horizontal plate 121 is brought into contact with the lower surface of the plate member 111.
Below the horizontal plate 121, a first plate 122, a second plate 123, and a third plate 124 are provided from the inside thereof.
The first plate 122 is a plate provided on an inner edge of the horizontal plate 121 and is perpendicular to the horizontal plate 121. The vertical length of the first plate 122 is shorter than the second plate 123 and the third plate 124. At the tip of the first plate 122, a bent portion 122A that bends outward is provided.
The second plate 123 is substantially perpendicular to the horizontal plate 121. In the middle of the second plate 123, a protruding portion 123A protruding inward is provided. The protruding portion 13A of the second plate 123 has a positional relationship corresponding to the bent portion 122A of the first plate 122. At the lower end of the second plate 123, a U-shaped member 123B having the same overall length as the second plate 123 and having a U-shaped cross section and opening upward is fitted. The width of the groove of the U-shaped member 123B is so small that the U-shaped member 123B does not come off from the second plate 123. The U-shaped member 123 </ b> B is for making the lower end of the second plate 123 round downwardly convex. If the object is achieved without the U-shaped member 123B, the U-shaped member 123B is not always necessary, or the U-shaped member 123B may be integrated with the second plate 123.
The third plate 124 is a plate provided on an outer edge of the horizontal plate 121 slightly inclined downward toward the outside, and is perpendicular to a portion of the horizontal plate 121 that is not inclined. The main role of the third plate 124 is to create an opening 129 that is a space between the second plate 123 and the third plate 124. The locking member 130 is fitted into the opening 129 as described later. The third plate 124 is also bent in a crank shape. The inner surface of the bent portion forms a locking portion 124A that protrudes into the opening 129.

The locking member 130 has a substantially U-shaped cross section. An edge of a first sheet, which will be described later, can be fixed to the long side 131 of the cross section of the locking member 130. Such fixing may be appropriately performed using a known technique. For example, the first sheet is fixed to the locking member 130 by bonding.
The short side 132 of the character of the cross section of the locking member 130 is configured to be slightly thicker than the long side 131, and a groove 132A is cut at the tip.
The locking member 130 can slightly reduce the angle on the small side between the long side 131 and the short side 132 of the cross section by applying an external force. . The locking member 130 can be pushed into the opening 129 with the above-mentioned angle reduced. The above-described angle of the locking member 130 pushed into the opening 129 returns to the original state by the elastic force. Then, the locking member 130 is locked by the locking portion 124 </ b> A in the groove 132 </ b> A, so that the locking member 130 is not pulled out from the opening 129 even if a force for pulling out from the opening 129 is applied.

The decorative material 140 includes a decorative plate 141 located below the decorative member 141 and two fixing plates 142 extending above the decorative plate 141. By sandwiching the lower end of the third plate 124 in the gap between the fixing plates 142, the decorative material 140 can be fixed to the lower end of the third plate 124. Although the fixing plate 142 is substantially perpendicular to the decorative plate 141 so as to be able to do so, the distance between them is narrowed toward the tip thereof. Thus, the third plate 124 is firmly held by the fixing plate 142 to such an extent that the decorative plate 141 does not fall off the third plate 124.
The lower surface of the decorative plate 141 is the lower end of the U-shaped member 123B attached to the lower end of the second plate 123 (more specifically, the lower surface of the first sheet that passes below the lower end of the U-shaped member 123B). It is made to be flush. Further, when the decorative material 140 is attached to the third plate 124, the inner edge of the decorative plate 141 is close to the lower end of the U-shaped member 123 </ b> B, and the outer edge thereof is on the outer side of the plate-shaped body 111. Its width is adjusted so that it is located just below the edge. When the decorative material 140 is fixed to the third plate 124, the decorative plate 141 is flush with a first sheet described later, and the inside of the opening 129, the third plate 124, and the vicinity of the outer end of the plate-like body 111 are: The state is hidden by the decorative board 141.

Next, a method of constructing a sheet structure using the fixing member 100 described above will be described.
As will be described later, the sheet structure includes, in addition to the fixing material 100, a first sheet, a second sheet, and an appropriate number of screws and filaments corresponding to the driving material of the present application. Note that a plurality of screws other than the above-mentioned screws are used to fix the sheet structure, more specifically, the fixing member 100 to the frame.
The first sheet used in this embodiment may be a film made of a single resin, a woven or woven fabric woven or knitted with fibers, or other woven or woven fabrics with fibers, for example. Alternatively, any material may be used, such as a film material typically formed by coating at least one surface of a base material which is a knitted fabric with a resin, or a sheet having a multilayered resin layer or the like. The first sheet is not necessarily required to have flame retardancy.
When the first sheet is a film made of a single resin, examples of the material include PVC, PE, PP, EVA, PU, PS, ABS, PA, PMMA, PC, and TPX.
When the first sheet is a film material, those described above can be used as the resin for coating the base material.
When the first sheet is a sheet, those described above can be used as the resin used for the resin layer therein.
The second sheet used in this embodiment has higher flame retardancy than the first sheet, and preferably has flame retardancy. For example, the second sheet is a glass cloth made of glass fiber, a carbon cloth made of carbon fiber, a fluorine fiber cloth made of fluorine fiber, a fluorine resin film, or the like.
In this embodiment, the first sheet is, but not limited to, a film made of PVC, and the second sheet is a glass cloth.

In order to make the sheet structure, first, the fixing member 100 and the second sheet are fixed to the skeleton B of the building. The skeleton B of the building is a pillar, a wall surface, a beam, a ceiling, or the like, but is not limited thereto. However, the skeleton B in this embodiment is a wall. Although not shown, the frame B, which is a wall, is assumed to exist in a direction perpendicular to the sheet structure. Although not limited to this, it is assumed that the frame B, which is the wall in this embodiment, is parallel.
To fix the fixing member 100, first, the upper member 110 is fixed to the skeleton B. For this purpose, the outer surface of the upper member 110 is brought into contact with the inner surface of the skeleton B which is a wall, and the tip of the screw 500 penetrating the upper member 110 is driven into the skeleton B. By driving a plurality of screws 500 at appropriate intervals in the length direction of the upper member 110, the upper member 110 is fixed to the frame B.
Next, the lower member 120 and the second sheet 210 are fixed to the upper member 110.
To do this, the lower surface of one side of the second sheet 210 prepared in advance into a predetermined shape (although the shape is not limited to this, it is assumed to be rectangular in this embodiment), is attached to the plate-like body 111 of the upper material 110. With the upper surface of the horizontal plate 121 of the lower member 120 being in contact with the lower surface of the plate-like body 111 of the upper member 110, the screw 300 is connected to the horizontal plate 121 of the lower member 120, Then, the plate-like body 111 of the upper material 110 and the second sheet 210 are made to penetrate all together. Thereby, the lower member 120 and the second sheet are fixed to the upper member 110 (FIG. 2). Similarly, also on the side opposite to one side of the second sheet 210, the fixing member 100 and the second sheet 210 are fixed to the frame B in a state where the left and right sides are reversed as shown in FIG. Thereby, the second sheet 210 is horizontally stretched between the two fixing members 100.
A screw 300 used to fix the lower member 120 and the second sheet to the upper member 110 is driven between the projecting portion 123A of the second plate 123 of the lower member 120 and the bent portion 122A of the first plate 122. . When projecting the screw 300, the projecting portion 123A of the second plate 123 and the bent portion 122A of the first plate 122 serve as a guide for the position at which the screw 300 is driven. A plurality of screws 300 are driven at appropriate intervals in the length direction of the fixing member 100. In this embodiment, but not necessarily, the screws 300 are driven at equal intervals. The distance between the screws 300 fixed to the two fixing members 100 is equal, and the screws 300 fixed to the two fixing members 100 are moved from the screw fixed to one fixing member 100 to the other fixing member 100. When a straight line perpendicular to the length direction of one fixing member 100 is drawn toward the fixing member 100, a screw 300 for fixing the other fixing member 100 exists at a position where the straight line intersects the other fixing member 100. I do. That is, the screws 300 are present at corresponding positions in the length direction of the two fixing members 100.
The length of one side of the second sheet 210 and the length of the side facing the second sheet 210 are set to be substantially the same as the length direction of the long length of the fixing material 100, and the length of the second sheet 210 is opposite to the length of one side. The distance to the side is adjusted to a length that is just enough to fix one side and the opposite side with the screws 300 used to fix the two fixing members 100 described above. In addition, when the decorative material 140 is later attached to the lower material 120, the outer edge of the decorative material 140 becomes the outer edge of the plate-like body 111 of the upper material 110. Adjust so that it comes directly below.
Next, the U-shaped member 123B is fitted and fixed to the lower end of the second plate 123. Note that the U-shaped member 123B may be fixed to the second plate 123 before fixing the fixing member 100 and the second sheet.

Next, the filament 400 is fixed to the screw 300.
A fishing line, a piano wire, or the like can be used for the striated body 400. As will be described later, the linear member 400 has a function of supporting the second sheet 210 from below. However, the linear member 400 must be thick enough to provide sufficient strength to prevent the second sheet from bending or falling. It can be used as appropriate.
The linear body 400 is located between the upper surface of the plate-like body 111 of the upper material 110 and the lower surface of the second sheet 210. The striated body 400 is fixed to the screw 300 in this embodiment, but not limited thereto. In this embodiment, the linear body 400 is fixed to the screw 300 by the frictional force between the striated body 400 and the screw 300 by making the screw 300 make a round, for example (FIGS. 3 and 5).
In this embodiment, two filaments 400 are used. One end of the fixing member 100 (for example, the fixing member 100 on the left side in FIG. 4) is fixed to the first screw 300 on one end side (for example, the upper side in FIG. 4) by one end of the fixing member 100, and the filament extended therefrom. The body 400 is wound around and fixed to the second screw 300 of the other fixing member 100, is fixed to the third screw 300 of the one fixing member 100, and so on, and the other end is one or the other. By being tied to the screw 300 fixed to the other fixing member 100, it is stretched in a zigzag manner between the two fixing members 100. In addition, the other fixing member 100 (for example, the right fixing member 100 in FIG. 4) is fixed by being tied to one end of the first screw 300 on one end side (for example, the upper side in FIG. 4), and is extended therefrom. The striated body 400 is fixed to the second screw 300 of one fixing member 100, fixed to the third screw 300 of the other fixing member 100, and so on, and the other end is set to one end. Alternatively, by being tied to a screw 300 fixed to the other fixing member 100, the two fixing members 100 are stretched in a zigzag manner. In order to support the second sheet 210 from below, a certain amount of tension is applied to the two linear members 400.
As described above, the distance between the screws 300 for fixing the two fixing members 100 is equal (that is, the lengths indicated by L in FIG. 4 are all equal), and the screws 300 for fixing the two fixing members 100 are one side. When a straight line perpendicular to the length direction of one fixing member 100 is drawn from the screw 300 driven into the fixing member 100 toward the other fixing member 100, the straight line intersects with the other fixing member 100. Since the screw 300 for fixing the other fixing member 100 is present, when the two striated members 400 are staggered between the fixing members 100, the striated member 400 becomes Between the two fixing members 100, a plurality of rhombuses continuous at the apex are continuously drawn.
Since the striated body 400 is stretched in this way, the striated body 400 supports the second sheet 210 from which it is difficult to apply tension from below, thereby preventing the second sheet 210 from bending downward. . If this is possible, the striated body 400 does not necessarily need to be stretched in a zigzag manner between the fixing members 100, and the striated body 400 does not need to be fixed to all the screws 300. However, when the striated body 400 is stretched between the two fixing members 100 so that a plurality of rhombus continuous at the apex are continuously drawn, the above-described rhombic fixing member 100 and If the angle α formed by the two striated bodies in the contacting part is set to 33.4 ° or less, the bending of the second sheet 210 in the downward direction can be effectively prevented. However, this is the case in this embodiment.

Next, the first sheet 220 is stretched between the two fixing members 100. The first sheet 220 has the same shape as the second sheet 210 in advance. However, the length from one side of the first sheet 220 to the side opposite to the first sheet 220 is adjusted in advance to an appropriate length to apply a tension in the direction perpendicular to the fixing member 100 to the first sheet 220 as described later. Keep it.
When the first sheet 220 is stretched, the locking member 130 having the same length as the entire length is fixed to one side and the side opposite to the first sheet 220. One side of the first sheet 220 and the side facing the first sheet 220 are fixed to the long side 131 of the hook of the locking member 130 as described above.
Next, by applying an external force to the locking member 130, the angle between the long side 131 and the short side 132 of the cross section is slightly narrowed, and the locking member 130 is pushed into the opening 129. With the locking member 130 pushed into the opening 129, the groove 132 </ b> A of the side 132 on the short side of the cross section is locked by the locking portion 124 </ b> A of the third plate 124, and a force is pulled out from the opening 129. Is not pulled out from the opening 129 (FIG. 6). This process is performed on the two fixing members 100.
When this processing is performed with the two fixing members 100, the first sheet 220 comes into contact with the lower end of the U-shaped member 123B slightly inside near one side and slightly inside near the opposing side thereof, and One side of 220 and the side opposite to it are fixed to the locking member 130 that has moved to a position higher than the lower end of the U-shaped member 123B in the opening 129, so that the U-shaped The lower end of the member 123B is bent upward. In this way, the first sheet 220 is stretched between the two fixing members 100 so as to be located below the second sheet 210. The height of the first sheet 220 is determined by the position of the lower ends of the U-shaped members 123B of the two fixing members 100. Unless there are special circumstances, the heights of the lower ends of the U-shaped members 123B of the two fixing members 100 are the same, so that the first sheet 220 stretched over the two fixing members 100 is practically horizontal. As described above, the height of the first sheet 220 can be determined by the position of the lower end of the U-shaped member 123B, but the position of the lower end of the U-shaped member 123B can be moved up and down by the length of the second plate 123. If a plurality of lower members 120 having different lengths of the second plate 123 are prepared, the interval between the first sheet 220 and the second sheet 210 can be changed. It is desirable that the interval between the first sheet 220 and the second sheet 210 is 100 mm or less.

Finally, the decorative material 140 is attached to the lower end of the third plate 124 of the lower member 120 of the two fixing members 100 (FIG. 7). Thereby, the decorative plate 141 of the decorative material 140 is flush with the lower surface of the first sheet 220 that is in contact with the lower end of the U-shaped member 123B, and the inside of the opening 129 and the third plate 124, and the plate-like shape. The vicinity of the outer end of the body 111 is hidden by the decorative board 141.
Thus, the sheet structure in this embodiment is completed.
