Description

Building structure and manufacturing method thereof

The present invention relates to a building structure in which a panel is fitted between a plurality of long materials arranged in parallel, and a method for manufacturing the same.

2. Description of the Related Art Conventionally, as a building structure, a plurality of long materials (for example, pillars and the like) arranged in the width direction and a hard panel fitted between the long materials so that the longitudinal directions thereof are parallel to each other are provided. A building structure is known (for example, Patent Document 1). For example, the panel is a heat insulating material made of synthetic resin.

In such a building structure, high accuracy of panel dimensions is required. Specifically, when the panel dimensions are slightly small, a gap is generated between the panel and the long material. Conversely, when the panel dimensions are slightly large, the panel cannot be fitted between the long materials. Or forcibly fitted panels may be damaged.

Japanese Unexamined Patent Publication No. 2003-278290

Therefore, in view of such circumstances, the present invention provides a building structure that can easily fit a panel between long materials and prevent a gap from being generated between the panel and the long material, and a method for manufacturing the same. The issue is to provide.

The building structure according to the present invention includes a plurality of long members arranged in parallel in a second direction orthogonal to the first direction, such that the longitudinal directions thereof are parallel to each other in the first direction, and the long A panel that is fitted between the scale members, and the panel has a plurality of cells that are elongated along a direction orthogonal to the second direction so as to have elasticity in the second direction. It is a foam.

According to the building structure according to the present invention, the plurality of long members are juxtaposed in the second direction orthogonal to the first direction so that the longitudinal directions of the long members are parallel to each other in the first direction. . Since the panel is a foam having a plurality of cells formed elongated along a direction orthogonal to the second direction, the panel has elasticity in the second direction. Therefore, when the panel compressed in the second direction is released and restored between the long materials (or the panel is fitted between the long materials while being compressed in the second direction), the panel is It is fitted between the long materials while being in close contact with the long material and pressing the long material.

Further, in the building structure according to the present invention, the plurality of cells are arranged such that an elastic modulus in the second direction of the panel is smaller than an elastic modulus in the first direction of the panel. It may be configured to be elongated along the direction of 1.

According to such a configuration, since the plurality of cells are formed long along the direction orthogonal to the second direction, the elastic modulus in the second direction of the panel is reduced. Thereby, since the panel has elasticity in the second direction, the panel is easily compressed in the second direction. Further, since the plurality of cells are elongated along the first direction among the directions orthogonal to the second direction, the elastic modulus in the first direction of the panel is increased. Accordingly, since the panel has rigidity in the first direction, the panel fitted between the long materials is stably held between the long materials.

Moreover, the manufacturing method of the building structure which concerns on this invention is the some elongate paralleled by the 2nd direction orthogonal to the said 1st direction so that a mutual longitudinal direction may become parallel in a 1st direction. A panel which is a foam having a plurality of cells elongated along a direction orthogonal to the second direction so as to have elasticity in the second direction with respect to the material. Fit in between.

As described above, the present invention has an excellent effect that a panel can be easily fitted between long materials, and a gap can be prevented from being generated between the panel and the long material.

DETAILED DESCRIPTION An embodiment of a building structure according to the present invention will be described below with reference to FIGS.

As shown in FIG.1 and FIG.2, the building structure 1 which concerns on this embodiment is the multiple (it is two figures in FIG.1 and FIG.2) arranged in the width direction so that a mutual longitudinal direction may become parallel. A long material 2 and a panel 3 fitted between the

long materials

2 and 2. The building structure 1 includes

frame members

4 and 4 that are fixed to end portions of the long material 2, and a plate member 5 that is fixed to a side portion of the long material 2. In the present embodiment, the building structure 1 is a wall.

The long material 2 includes

support surfaces

21 and 21 that support the panel 3 on both sides in the width direction. Specifically, the cross-sectional shape of the long material 2 is a rectangular shape. The plurality of long materials 2 are arranged so that the support surfaces 21 face each other. In the present embodiment, the long material 2 is a pillar, and is arranged so that the longitudinal direction is parallel to the height direction.

The panel 3 is formed in a rectangular parallelepiped shape. In the state in which the panel 3 is fitted between the

long members

2 and 2, the longitudinal direction of the panel 3 and the longitudinal direction of the long member 2 are parallel, and the width direction of the panel 3 and the width direction of the long member 2. And are parallel.

In the present invention, the direction parallel to the longitudinal direction of the long material 2 is referred to as a first direction D1 of each of the building structure 1, the long material 2 and the panel 3, and is parallel to the direction in which the long materials 2 are juxtaposed. The direction is referred to as the second direction D2 of the building structure 1, the long material 2 and the panel 3, and the direction perpendicular to the first direction D1 and the second direction D2 is the building structure 1, long length. Each of the material 2 and the panel 3 is referred to as a third direction D3.

That is, in the present embodiment, the first direction D1 of the panel 3 is the longitudinal direction (vertical direction) of the panel 3, the second direction D2 of the panel 3 is the width direction of the panel 3, and The third direction D3 is the thickness direction of the panel 3. Hereinafter, the directions corresponding to the first to third directions D1, D2, and D3 are denoted by D1, D2, and D3, respectively.

As shown in FIGS. 3 and 4, the panel 3 is formed of a synthetic resin (for example, urethane resin, styrene resin, phenol resin, etc.) and is a foam having elasticity. Specifically, the panel 3 is a foam having a plurality of cells 31 that are formed in a long direction along a direction orthogonal to the width direction D2 so as to have elasticity in the width direction D2.

In the present invention, it is not necessary for all the cells 31 to be elongated along the direction perpendicular to the second direction D2, and the panel 3 has elasticity in the second direction D2. For example, more than half of the cells 31 need only be formed long along a direction orthogonal to the second direction D2. That is, in the present invention, as long as the panel 3 has elasticity in the second direction D2, the cells 31 that are elongated along the direction parallel to the second direction D2 may be provided. .

The panel 3 is formed so that the elastic modulus in the width direction D2 is smaller than the elastic modulus in the longitudinal direction D1. The panel 3 is formed so that the elastic modulus in the width direction D2 and the elastic modulus in the thickness direction D3 are substantially the same.

Specifically, the panel 3 has a plurality of cells 31 that are elongated along the longitudinal direction D1 in the direction orthogonal to the width direction D2, so that the elastic modulus in the width direction D2 is the same as that in the longitudinal direction D1. It is formed so as to be smaller than the elastic modulus. More specifically, the plurality of cells 31 are arranged with the longest dimension along the longitudinal direction D1, so that the elastic modulus in the width direction D2 and the thickness direction D3 of the panel 3 is the longitudinal direction D1. It is smaller than the elastic modulus.

The elastic modulus is a ratio between stress and strain (deformation amount) within the elastic range when the panel 3 is deformed by applying an external force. In other words, the smaller the elastic modulus, the greater the amount of deformation with the same stress (pressure).

Since the dimension W2 in the width direction D2 of the panel 3 that is not elastically deformed is larger than the separation distance W1 between the

long materials

2 and 2, the panel 3 is compressed and deformed in the width direction D2 and It is fitted between the two. The dimension W2 in the width direction D2 of the panel 3 that is not elastically deformed is preferably 101% to 115%, more preferably 105% to 110% of the separation distance W1 of the

long materials

2 and 2.

In this embodiment, the panel 3 is a polyurethane foam panel. The configuration of the panel 3 will be described in detail below.

The panel 3 is obtained by mixing and reacting a polyol composition containing a polyol compound and water as a foaming agent, and a polyisocyanate component. The panel 3 has a longitudinal direction (longitudinal direction) D1, a width direction D2, and a thickness direction D3. a polyurethane foam panel with the ratio of 10% compression strength _{S D2} of a 10% compression strength _{S D1} and the width direction D2 of the foam density is 15 kg / ^{m 3} or less and a vertical direction D1 _{_(S} D1 _/ S _D2) is It is set to be 2 or more.

The foam density (core density) of the panel 3 is preferably 15 kg / m ³ or less, more preferably 13 kg / m ³ or less, and further preferably 11 kg / m ³ or less. Such foam density is set within the above range, for example, by adjusting the amount of water as a blowing agent to 20 to 100 parts by weight (with respect to 100 parts by weight of the polyol compound). Here, the foam density is a value measured according to JIS K7222.

Since the foam density of the panel 3 is 15 kg / m ³ or less, it is very low, and the expansion ratio of the panel 3 is high. Therefore, the cell 31 is stretched in the vertical direction D1 and formed in an ellipsoidal shape. When the major axis direction of the ellipsoidal cell 31 is parallel to the longitudinal direction D1 of the panel 3, the foam strength in the longitudinal direction D1 of the panel 3 is increased, while the foam strength in the width direction D2 and the thickness direction D3 of the panel 3 is increased. The width direction D2 and the thickness direction D3 of the panel 3 have elasticity (flexibility).

Panel 3, so that the ratio between the 10% compressive strength _{S D2} of a 10% compression strength _{S D1} and the width direction D2 in the vertical direction D1 _{_(S} D1 _/ S _D2) is 2 or more, are formed. And workability fitting the panel 3 between the

long material

2,2, in order to achieve both autonomy fitted

panels

3, 10% compressive strength of 10% compression strength S _D1 and the width direction D2 of the longitudinal direction D1 The ratio to S _D2 (S _D1 / S _D2 ) is preferably 3 or more, and more preferably 5 or more. The upper limit of the ratio (S _D1 / S _D2 ) is not particularly limited, but is about 7, for example. The X% compressive strength is a stress necessary for compressing and deforming the panel 3 by an amount of X%.

In order to improve the workability of fitting the panel 3 between the

long materials

2 and 2, the panel 3 needs to be easily compressed in the width direction D2. Thus, 10% compression strength _{S D2} in the width direction D2 of the panel 3, it is preferably 3N / cm ² or less, more preferably 1N / cm ² or less, 0.5 N / cm ² or less Is particularly preferred.

Also, in order to improve the workability of fitting the panel 3 between the

long materials

2 and 2, it is necessary that the compressed panel 3 is quickly restored. Therefore, when the panel 3 is not damaged or destroyed even if it is compressed 20% in the width direction D2, and is opened after being compressed 20% in the width direction D2, the panel 3 has a dimension of 90 in the width direction D2 before compression. It is preferable to restore to% or more.

In the panel 3, it is preferable that the foaming direction of the cells 31 is substantially perpendicular to the width direction D2 and the thickness direction D3, respectively. Specifically, “substantially vertical” means 90 ° ± 15 °, particularly 90 ° ± 10 °. The “cell foaming direction” means a major axis direction when the shape of each cell 31 is regarded as an ellipsoid, and in particular, a central portion of the panel 3 in the width direction D2 (the vertical direction D1 and the width direction D2). The direction when measured from the center at a portion of about 10% on both sides of the dimension in the longitudinal direction D1 and the dimension in the width direction D2 is assumed.

Since the panel 3 is used as a heat insulating material, the thermal conductivity λ of the panel 3 is preferably 0.04 W / m · K or less. Thereby, even if it is the panel 3 reduced in density, sufficient heat insulation performance can be exhibited. The thermal conductivity is a value measured according to JIS A1412-2.

The closed cell ratio of panel 3 is preferably 15% or less, and more preferably 0 to 10%. Thus, by increasing the communication rate, excellent dimensional stability can be ensured. Here, the closed cell ratio is a value measured according to ASTM D2856.

As described above, the panel 3 is obtained by mixing and reacting a polyol composition containing a polyol compound and water as a foaming agent and a polyisocyanate component.

The polyol compound has an average functional group number of 2 to 4 and a weight average molecular weight of 3000 to 8000, a polyether polyol (A) which is a polymer of alkylene oxide, and a short glycol (B And).

The polyether polyol (A) is a polyoxyalkylene polyol obtained by ring-opening addition polymerization of alkylene oxide to an initiator having 2 to 4 active hydrogen atoms.

Examples of the initiator include aliphatic polyhydric alcohols (for example, ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, 1,4-butanediol, 1,3-butanediol, 1,6-hexanediol, neopentyl Glycols such as glycol, cyclohexylene glycol and cyclohexanedimethanol, triols such as trimethylolpropane and glycerin, tetrafunctional alcohols such as pentaerythritol), aliphatic amines (eg ethylenediamine, propylenediamine, butylenediamine, hexamethylene) Alkylenediamines such as diamine and neopentyldiamine, alkanolamines such as monoethanolamine and diethanolamine), aromatic amines (eg, 2,4-toluenedia) Emissions, 2,6-toluene diamine, diethyl toluene diamine, 4,4'-diaminodiphenylmethane, p- phenylenediamine, o- phenylenediamine, naphthalene diamines, etc.) and the like.

The hydroxyl value of the polyether polyol (A) is preferably 20 to 100 mgKOH / g, and more preferably 30 to 60 mgKOH / g. When the hydroxyl value is less than 20 mgKOH / g, the viscosity ratio of the polyol composition to the polyisocyanate component becomes high, resulting in poor stirring during mixing. On the other hand, when it exceeds 100 mgKOH / g, it becomes difficult to impart moderate toughness to the obtained polyurethane foam. The hydroxyl value is a value measured according to JIS K1557-1: 2007.

Of these, diethylene glycol, dipropylene glycol and glycerin are preferable, and diethylene glycol is particularly preferable in order to increase the resin strength of the foam more reliably. The molecular weight of the short glycol (B) is preferably 62 to 200 mgKOH / g, and more preferably 90 to 150 mgKOH / g.

In the polyol composition used as a raw material, the polyol compound further contains a polyether polyol (C) which has an average functional group number of 2 to 4 and a weight average molecular weight of 3000 to 5000 and is a propylene oxide polymer. It is preferable. The polyether polyol (C) is a polyoxyalkylene polyol obtained by ring-opening addition polymerization of propylene oxide alone to an initiator having 2 to 4 active hydrogen atoms. Examples of the initiator include the aliphatic polyhydric alcohols, aliphatic amines, and aromatic amines described above, and are not particularly limited. As the initiator, glycerin is particularly preferable.

The polyol composition used as a raw material contains 10 to 80 parts by weight of the polyether polyol (A) in 100 parts by weight of the polyol compound in order to produce a polyurethane foam panel 3 having a low density and excellent heat insulating performance. It is preferable to contain 10 to 60 parts by weight of the short glycol (B), more preferably 15 to 70 parts by weight of the polyether polyol (A), and more preferably 10 to 50 parts by weight of the short glycol (B).

More preferably, it is contained in an amount of 40 to 60 parts by weight.

In the polyol composition, water is blended as a foaming agent. The blowing agent is preferably water alone, and the blending amount thereof is preferably 20 to 100 parts by weight, more preferably 30 to 90 parts by weight, more preferably 40 to 40 parts by weight based on 100 parts by weight of the polyol compound. More preferably, it is 80 parts by weight. Thus, the density of the panel 3 can be reduced by blending a large amount of water.

The flame retardant, catalyst and foam stabilizer are usually further added to the polyol composition. Moreover, various additives, such as a coloring agent and antioxidant, may further be mix | blended with the said polyol composition.

Examples of the flame retardant include metal compounds such as organophosphates, halogen-containing compounds, and aluminum hydroxide. Particularly, organophosphates are preferable because they have an effect of reducing the viscosity of the polyol composition. Examples of the organic phosphate esters include halogenated alkyl esters, alkyl phosphate esters, aryl phosphate esters, and phosphonate esters of phosphoric acid. Specific examples include tris (chloropropyl) phosphate (TMCPP, manufactured by Daihachi Chemical), tributoxyethyl phosphate (TBEP), tributyl phosphate, triethyl phosphate, trimethyl phosphate, cresyl diphenyl phosphate, and the like. The blending amount of the flame retardant is preferably 10 to 50 parts by weight, more preferably 15 to 40 parts by weight with respect to 100 parts by weight of the polyol compound. In particular, in order to prevent deterioration of the brittleness of the foam, in addition to the polyether polyol (A) and the short glycol (B) in the polyol composition, the flame retardant is 20 parts by weight with respect to 100 parts by weight of the polyol compound. It is preferable to contain above.

The catalyst is not particularly limited as long as it is a catalyst that accelerates the urethanization reaction, but it is preferable to use a reactive amine catalyst that can react with the isocyanate group of the polyisocyanate component.

It is preferable to use liquid diphenylmethane diisocyanate (MDI) from the viewpoint of ease of handling, speed of reaction, excellent physical properties of the resulting polyurethane foam, and low cost. Liquid MDIs include Crude MDI (c-MDI) (44V-10, 44V-20, etc. (manufactured by Sumika Bayer Urethane Co., Ltd.), Millionate MR-200 (Nippon Polyurethane Industry)), uretonimine-containing MDI (Millionate MTL: Nippon Polyurethane) (Made by industry) etc. are mentioned. In addition to liquid MDI, other polyisocyanate compounds may be used in combination. As the polyisocyanate compound to be used together, polyisocyanate compounds known in the technical field of polyurethane can be used without limitation.

Panel 3 preferably has an isocyanate index (NCO Index) of 30 or less, more preferably less than 30, when the polyol composition and the polyisocyanate component are mixed and reacted. As a minimum of an isocyanate index, 20 is mentioned, for example. By setting the isocyanate index within the above range, the polyurethane foam panel 3 having low density and excellent elasticity and heat insulation performance can be obtained. Here, the isocyanate index is the percentage equivalent of the isocyanate group of the polyisocyanate component to all active hydrogen groups contained in the polyol composition (calculated using water as a blowing agent as a bifunctional active hydrogen compound). (Equivalent ratio of isocyanate groups to 100 equivalents of active hydrogen groups).

The manufacturing method of the panel 3 is a manufacturing method of the polyurethane foam panel 3 obtained by making into a raw material the foaming stock solution composition containing the polyol composition containing the polyol compound and water which is a foaming agent, and a polyisocyanate component. Thus, for example, such a polyol compound has a polyol composition having an average functional group number of 2 to 4, a weight average molecular weight of 3000 to 8000, and a polyether polyol (A) which is a polymer of alkylene oxide, and a molecular weight.

In order for the plurality of cells 31 to be formed along the longitudinal direction D1 of the panel 3 so that the panel 3 has elasticity in the width direction D2, as shown in FIG. With respect to the mold 7 having the width direction D2 and the thickness direction D3, an injection step of injecting the foaming stock solution composition with the surface extending along the width direction D2 and the thickness direction D3 as the bottom surface 71, and the foaming stock solution composition after the injection step It is preferable to provide a reaction step.

Specifically, in the manufacturing method of the panel 3, the mixing head 8 has a bottom surface 71 as a surface extending along the width direction D2 and the thickness direction D3 with respect to the mold 7 having the vertical direction D1, the width direction D2, and the thickness direction D3. Then, a foaming stock solution composition containing a polyol composition and a polyisocyanate component is injected (injection step). After injection, the foamed stock solution composition reacts and forms a foam while foaming (swelling) in the longitudinal direction D1 (reaction process). In the reaction step, the mold 7 may be heated as a whole or locally as necessary.

The configuration of the building structure 1 according to this embodiment is as described above. Next, a method for manufacturing the building structure 1 according to this embodiment will be described below with reference to FIG.

As shown in FIG. 6, the plurality of

long materials

2 and 2 are juxtaposed in the width direction D2 so that the longitudinal direction D1 is parallel. By applying an external force to the panel 3, the panel 3 is compressed in the width direction D2. Accordingly, the dimension W2 in the width direction D2 of the panel 3 which is larger than the separation distance W1 between the

long materials

2 and 2 is smaller than the separation distance W1 between the

long materials

2 and 2.

After the panel 3 compressed in the width direction D2 is positioned between the

long materials

2 and 2, the applied external force is released, so that the panel 3 is restored. Since the panel 3 tries to be further restored by the elastic force even after contacting the support surface 21 of the long material 2, the long material 2 is in close contact with the long material 2 and presses the long material 2. , Fits between the two.

As described above, according to the building structure 1 according to the present embodiment, the plurality of long members 2 are orthogonal to the first direction D1 such that the longitudinal directions of the plurality of long members 2 are parallel to each other in the first direction D1. Two directions D2 are arranged in parallel. Since the panel 3 is a foam having a plurality of cells 31 that are elongated along a direction orthogonal to the second direction D2, the panel 3 has elasticity in the second direction D2.

Therefore, when the panel 3 compressed in the second direction D2 is decompressed and restored between the

long members

2 and 2, the panel 3 is in close contact with the long member 2 and the long member 2 is attached. It fits between the

long materials

2 and 2 in the pressed state. As described above, the building structure 1 according to this embodiment allows the panel 3 to be easily fitted between the

long members

2 and 2 and prevents a gap from being generated between the panel 3 and the long member 2. it can.

Moreover, according to the building structure 1 which concerns on this embodiment, since the several cell 31 is formed elongate along the direction orthogonal to the 2nd direction D2, the elasticity in the 2nd direction D2 of the panel 3 is provided. The rate is reduced. Thereby, since the panel 3 has elasticity in the second direction D2, the panel 3 is easily compressed in the second direction D2.

Further, since the plurality of cells 31 are formed along the first direction D1 out of the directions orthogonal to the second direction D2, the elastic modulus of the panel 3 in the first direction D1 is large. Become. Thereby, since the panel 3 has rigidity in the first direction D1, the panel 3 fitted between the

long materials

2 and 2 is stably held between the

long materials

2 and 2. As a result, the panel 3 can stand on its own.

In addition, since the plurality of cells 31 are elongated along the first direction D1 among the directions orthogonal to the second direction D2, the heat insulation performance in the third direction D3 of the panel 3 is improved. It can also be made.

In addition, this invention is not limited to the structure of above-described embodiment, and is not limited to the above-mentioned effect. It goes without saying that the present invention can be variously modified without departing from the gist of the present invention. For example, it is needless to say that configurations, methods, and the like according to various modifications described below may be arbitrarily selected and employed in the configurations, methods, and the like according to the above-described embodiments.

In the building structure 1 according to the above embodiment, one panel 3 is configured to be fitted between the

long materials

2 and 2. However, the present invention is not limited to such a configuration. For example, in the present invention, as shown in FIG. 7, a plurality of panels 3 may be arranged in parallel in the first direction D <b> 1 and fitted between the

long members

2 and 2. As shown, a plurality of panels 3 may be arranged in parallel in the second direction D2 and fitted between the

long materials

2 and 2.

In the building structure 1 shown in FIG. 7, when the first direction D <b> 1 is configured to be the height direction, the panel 3 includes a plurality of cells 31 that are elongated along the first direction D <b> 1. Thus, it is preferable that the elastic modulus in the width direction D2 is formed to be smaller than the elastic modulus in the longitudinal direction D1. Thereby, since the panel 3 has rigidity in the first direction D1, the panel 3 fitted between the

long materials

2 and 2 can not only stand alone, but also the panel 3 arranged on the upper side can be stably provided from below. I can support it.

In the building structure 1 shown in FIG. 8, adjacent

panel end portions

32, 32 abut at positions deviated from between the

long materials

2, 2, and the opposite

panel end portions

33, 33 are long. It is located between the

scale members

2 and 2 and is in contact with the long member 2 and the plate member 5. And the panel 3 receives external force so that the adjacent

panel edge parts

32 and 32 are located between the

elongate materials

2 and 2, and the panel 3 is compressed in the 2nd direction D2, while the

elongate materials

2 and 2 are received. Fit between two.

Moreover, in the building structure 1 according to the above-described embodiment, the panel 3 is configured such that the dimension in the first direction D1 is larger than the dimension in the second direction D2. However, the present invention is not limited to such a configuration. For example, in the present invention, as shown in FIG. 7, the panel 3 may be formed such that the dimension in the first direction D1 is smaller than the dimension in the second direction D2.

In the above embodiment, the long material 2 is a pillar, and the building structure 1 is a wall. However, the present invention is not limited to such a configuration. For example, in the present invention, the long material 2 may be a floor joist in which the first direction (longitudinal direction) D1 is a horizontal direction, and the building structure 1 may be a floor. The long material 2 may be a ceiling joist in which the first direction (longitudinal direction) D1 is the horizontal direction, and the building structure 1 may be a ceiling. 1 may be a rafter whose direction (longitudinal direction) D1 is inclined with respect to the vertical direction and the horizontal direction, and the building structure 1 may be a roof. In short, in the present invention, the first to third directions D1, D2, and D3 are not limited to specific directions.

In the above embodiment, the panel 3 is manufactured using the mold 7. However, the present invention is not limited to such a configuration. For example, in the present invention, a configuration may be employed in which the foaming stock solution composition is spread on a conveyor, and the panel 3 is cut into a rectangular parallelepiped shape so that the vertical direction is the first direction D1.

In the present invention, as shown in FIG. 9, the panel 3 may be provided with a tapered portion 34 that is inclined with respect to the third direction D3 at the end in the second direction D2. The panel 3 is formed by the tapered portion 34 so that the dimension in the second direction D2 is gradually increased. The panel 3 is fitted between the

long materials

2 and 2 while being compressed in the second direction D2 by being pressed in the third direction D3. The tapered portion 34 may be provided only at one end of the panel 3.

Further, in the present invention, as shown in FIG. 10, a stop portion 6 that protrudes from the long material 2 in the second direction D2 and stops the panel 3 fitted between the

long materials

2 and 2 is provided. It may be configured. The stop portion 6 includes a locking portion 61 that locks the panel 3 fitted between the

long members

2 and 2 in the second direction D2, and an inclined portion 62 that is inclined with respect to the third direction D3. ing.

According to such a configuration, the panel 3 is compressed in the second direction D2 by the inclined portion 62 of the stopper 6 when pressed in the third direction D3. The panel 3 is fitted between the

long materials

2 and 2 by getting over the stopper 6. Since the panel 3 fitted between the

long members

2 and 2 is locked to the stopper 6, it is prevented from coming out between the

long members

2 and 2.

In the present invention, the panel 3 may be configured such that the surface thereof is covered with a film (for example, a shrink film made of vinyl or the like). According to such a configuration, when the panel 3 is held by an operator or when a plurality of panels 3 are stacked, the panel 3 can be easily handled.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.
