An embodiment of the building structure of the present invention will be described below with reference to Figs. 1 to 6 .

As shown in FIG. 1 and FIG. 2, the building structure 1 of the present embodiment includes a plurality of parallel rows in the longitudinal direction so as to be parallel to each other in the longitudinal direction (in FIG. 1 and FIG. 2, two are shown). The strip material 2; and the panel 3 embedded between the strips 2 and 2. The building structure 1 includes a frame member 4 and 4 fixed to an end portion of the elongated material 2, and a plate member 5 fixed to a side portion of the elongated material 2. In the present embodiment, the building structure 1 is a wall.

The elongated material 2 is provided with support faces 21 and 21 of the support panel 3 on both sides in the width direction. Specifically, the cross-sectional shape of the elongated material 2 is a rectangular shape. The plurality of strips 2 are arranged such that the support faces 21 face each other. In the present embodiment, the elongated material 2 is a column and is disposed such that its longitudinal direction is parallel to the height direction.

The panel 3 is formed in a rectangular parallelepiped shape. In a state in which the panel 3 is fitted between the elongated materials 2 and 2, the longitudinal direction of the panel 3 is parallel to the longitudinal direction of the elongated material 2, and the width direction of the panel 3 is parallel to the width direction of the elongated material 2.

In the present invention, the direction parallel to the longitudinal direction of the long material 2 refers to the first direction D1 of each of the building structure 1, the elongated material 2, and the panel 3, and is parallel to the direction of the parallel strip material 2. The second direction D2 of each of the building structure 1, the long material 2, and the panel 3, and the direction orthogonal to the first direction D1 and the second direction D2 means the building structure 1, the elongated material 2, and the panel 3 The third direction of each is D3.

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

As shown in FIG. 3 and FIG. 4, the panel 3 is a foam which is formed of a synthetic resin (for example, an urethane resin, a styrene resin, a phenol resin, or the like) and has elasticity. Specifically, the panel 3 has a foam having a plurality of cells 31 formed in a long direction orthogonal to the width direction D2, and has elasticity in the width direction D2.

Furthermore, in the present invention, it is not necessary for all of the cells 31 to be formed in a strip in a direction orthogonal to the second direction D2, and for example, more than half of the cells are provided such that the panel 3 has elasticity in the second direction D2. 31 may be formed in a strip 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, a unit 31 formed in a strip shape in a direction parallel to the second direction D2 may be provided.

The panel 3 is formed such that the elastic modulus in the width direction D2 is smaller than the elastic modulus in the longitudinal direction D1. Further, the panel 3 is formed such that the modulus of elasticity in the width direction D2 is substantially the same as the modulus of elasticity in the thickness direction D3.

Specifically, the panel 3 is formed by making the plurality of cells 31 elongated in the longitudinal direction D1 in the direction orthogonal to the width direction D2, and the elastic modulus in the width direction D2 is smaller than the elastic mode of the longitudinal direction D1. The way of the number is formed. More specifically, by arranging the plurality of cells 31 in the longitudinal direction D1 in the direction of the longest dimension, the elastic modulus of the width direction D2 and the thickness direction D3 of the panel 3 is smaller than the elastic mode of the length direction D1. number.

Further, the elastic modulus is a ratio of stress to strain (amount of deformation) in the elastic range when an external force is applied to the panel 3 to deform it. In other words, the smaller the modulus of elasticity, The same amount of stress (pressure) is deformed.

Since the dimension W2 of the width direction D2 of the panel 3 which is not elastically deformed is larger than the distance W1 of the strip materials 2 and 2, the panel 3 is embedded in the strip material 2 in a state of being compressed and deformed in the width direction D2. 2 rooms. The dimension W2 of the width direction D2 of the panel 3 which is not elastically deformed is preferably 101% to 115%, more preferably 105% to 110%, of the distance W1 between the strips 2 and 2.

In the present embodiment, the panel 3 is a polyurethane foam panel. The constitution 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) with a polyisocyanate component, and having a polyurethane in the longitudinal direction (longitudinal direction) D1, the width direction D2, and the thickness direction D3. foam panels, and is set to become foam density 15kg / m ³ or less, and 10% of the longitudinal compressive strength D1 _D1 the width direction D2 S 10% of the compressive strength ratio S _D2 (S _D1 / S _D2) becomes 2 or more.

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

The foam density of the panel 3 is 15 kg/m ³ or less, so it is very low, and the expansion ratio of the panel 3 is high. Therefore, the unit 31 is stretched in the longitudinal direction D1 to be formed into an ellipsoidal shape. By making the major axis direction of the ellipsoidal unit 31 parallel to the longitudinal direction D1 of the panel 3, the foam strength in the longitudinal direction D1 of the panel 3 is increased, and on the other hand, the foam strength in the width direction D2 and the thickness direction D3 of the panel 3 is lowered. The width direction D2 and the thickness direction D3 of the panel 3 are elastic (flexibility).

3 longitudinal panel lines D1 to 10% of the compressive strength and the width direction D2 _D1 S 10% of the compressive strength ratio S _D2 (S _D1 / S _D2) of 2 or more is formed becomes. In order to combine the workability of embedding the panel 3 between the elongated materials 2 and 2 and the self-supporting property of the panel 3 to be embedded, it is preferable to compress the 10% compressive strength S _D1 and the width direction D2 of the longitudinal direction D1. The ratio of the strength S _D2 (S _D1 /S _D2 ) is 3 or more, and more preferably 5 or more. The upper limit of the ratio (S _D1 /S _D2 ) is not particularly limited, and is, for example, about 7. Further, the X% compressive strength is a stress necessary for only compressing the panel 3 by an amount of X%.

In order to improve the workability of embedding the panel 3 between the elongated materials 2 and 2, it is necessary to easily compress the panel 3 in the width direction D2. Therefore, the 10% compressive strength S _D2 of the width direction D2 of the panel 3 is preferably 3 N/cm ² or less, more preferably 1 N/cm ² or less, and particularly preferably 0.5 N/cm ² or less.

Further, in order to improve the workability of embedding the panel 3 between the long materials 2 and 2, it is necessary to quickly restore the compressed panel 3. Therefore, it is preferable that the panel 3 is not damaged or broken even if it is compressed by 20% in the width direction D2, and can be restored to the width before compression when the compression is released after being compressed by 20% in the width direction D2. More than 90% of the size of the direction D2.

Preferably, the panel 3 has a foaming direction of the unit 31 which is substantially perpendicular to the width direction D2 and the thickness direction D3. By "substantially perpendicular", specifically, it means 90 ° ± 15 °, especially 90 ° ± 10 °. The term "foaming direction of the unit" means the direction of the major axis when the shape of each unit 31 is regarded as an elliptical shape, and particularly refers to the central portion of the width direction D2 of the panel 3 (from the center of the longitudinal direction D1 and the width direction D2). The direction to the measurement is made to the portion of the dimension of the longitudinal direction D1 and the portion of the dimension D2 which is about 10% on both sides.

Since the panel 3 can be used as a heat insulating material, the thermal conductivity of the panel 3 is λ. It is preferably 0.04 W/m‧K or less. Thereby, even if it is the panel 3 which is low density, it can exhibit sufficient heat insulation performance. Further, the thermal conductivity is a value measured in accordance with JIS A1412-2.

The closed cell ratio of the panel 3 is preferably 15% or less, more preferably 0 to 10%. Thus, by increasing the connectivity ratio, excellent dimensional stability can be ensured. Here, the independent bubble ratio is a value measured in accordance with ASTM D2856.

As shown in FIG. 6, a plurality of strips 2 and 2 are parallel in the longitudinal direction D1. The manner is juxtaposed in the width direction D2. The panel 3 is compressed in the width direction D2 by applying an external force to the panel 3. Thereby, the dimension W2 of the width direction D2 of the panel 3 which is larger than the distance W1 of the long strips 2, 2 becomes smaller than the distance W1 of the strip material 2, 2.

After the panel 3 compressed in the width direction D2 is placed between the elongated materials 2 and 2, the applied external force is released, thereby restoring the panel 3. After the panel 3 abuts against the support surface 21 of the long material 2, the panel 3 is also restored by the elastic force, so that it is embedded in the strip material 2, 2 in a state in which it is adhered to the strip material 2 and the strip material 2 is pressed. between.

Further, according to the building structure 1 of the present embodiment, since the plurality of units 31 are formed in a long direction in a direction orthogonal to the second direction D2, the modulus of elasticity of the panel 3 in the second direction D2 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 in a long direction along the first direction D1 in the direction orthogonal to the second direction D2, the elastic modulus of the first direction D1 of the panel 3 is increased. Big. Thereby, since the panel 3 has rigidity in the first direction D1, the panel 3 interposed between the elongated materials 2 and 2 can be stably held between the elongated materials 2 and 2. The result panel 3 is self-supporting.

Further, since the plurality of cells 31 are formed in a long direction along the first direction D1 in the direction orthogonal to the second direction D2, the heat insulating performance in the third direction D3 of the panel 3 can be improved.

Furthermore, the present invention is not limited to the configuration of the above embodiment, and is not limited to the above-described effects. It is apparent that various modifications can be made without departing from the spirit and scope of the invention.

The building structure 1 of the above embodiment has a configuration in which one panel 3 is fitted between the elongated materials 2 and 2. However, the present invention is not limited to this configuration. For example, in the present invention, as shown in FIG. 7, the panel 3 may be arranged in parallel in the first direction D1 and embedded in the strips 2 and 2, or may be as shown in FIG. The configuration is such that the panel 3 is placed in parallel in the second direction D2 and embedded between the elongated materials 2 and 2.

In the case where the building structure 1 shown in FIG. 7 is configured such that the first direction D1 is in the height direction, the panel 3 is preferably formed in a long strip by the plurality of units 31 along the first direction D1. It is formed such that the elastic modulus of the width direction D2 is smaller than the elastic modulus of the longitudinal direction D1. Thereby, since the panel 3 has rigidity in the first direction D1, the panel 3 interposed between the elongated materials 2 and 2 can be self-supported, and the panel 3 disposed above can be stably supported from below.

In the building structure 1 shown in Fig. 8, the adjacent panel end portions 32, 32 are abutted from a position offset from the strip materials 2, 2, and the opposite end panel end portions 33, 33 are respectively positioned. Between the strips 2 and 2, the strip 2 and the sheet 5 are abutted. Then, the panel 3 is subjected to an external force so that the adjacent panel end portions 32 and 32 are located between the elongated materials 2 and 2, whereby the panel 3 is compressed in the second direction D2 and embedded in the strip material 2, 2 between.

Further, the building structure 1 of the above-described embodiment has a configuration in which the panel 3 is formed 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 this configuration. For example, in the present invention, as shown in FIG. 7, the panel 3 may be formed such that the dimension of the first direction D1 is smaller than the dimension of the second direction D2.

Further, in the above embodiment, the configuration is such that the long material 2 is a column and the building structure 1 is a wall. However, the present invention is not limited to this 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, or may be as follows. The long material 2 is a first direction (longitudinal direction) D1 is a horizontal ceiling joist, and the building structure 1 is a ceiling. Further, the structure may be as follows: the long material 2 is a first direction (longitudinal direction) D1 is a vertical direction and a direction inclined with respect to the horizontal direction, and the building structure 1 is a roof. In short, in the present invention, the first to third directions D1, D2, and D3 are not limited to a specific direction.

Moreover, in the above embodiment, the panel 3 is manufactured using the mold 7. However, the present invention is not limited to this configuration. For example, in the present invention, the foaming stock solution may be sprayed onto the conveyor, and the panel 3 may be cut into a rectangular parallelepiped shape so that the vertical direction becomes the first direction D1.

Further, in the present invention, as shown in FIG. 9, the panel 3 may have a tapered portion 34 that is inclined with respect to the third direction D3 at the end portion of the second direction D2. The panel 3 is formed by the tapered portion 34 so as to gradually increase in size in the second direction D2. The panel 3 by the first The three directions D3 are pressed, and one side is compressed in the second direction D2 and embedded between the elongated materials 2 and 2. Furthermore, 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 fixing portion 6 in which the long strip material 2 protrudes in the second direction D2 and is fixed to the panel 3 interposed between the elongated materials 2 and 2 may be provided. The fixing portion 6 includes a locking portion 61 that locks the panel 3 that is fitted between the elongated materials 2 and 2 in the second direction D2, and an inclined portion 62 that is inclined with respect to the third direction D3.

According to this configuration, the panel 3 is pressed in the third direction D3, and is compressed by the inclined portion 62 of the fixing portion 6 in the second direction D2. The panel 3 is embedded between the elongated materials 2 and 2 by passing over the fixing portion 6. Since the panel 3 embedded between the long strips 2 and 2 is locked to the fixing portion 6, it is possible to prevent separation from the strip materials 2 and 2.

Further, in the present invention, the surface of the panel 3 may be covered with a film (for example, a shrink film made of ethylene or the like). According to this configuration, when the operator holds the panel 3 or when a plurality of panels 3 are stacked, the operation of the panel 3 is facilitated.

Thereafter, the polyurethane foam panel 3 obtained by reacting the foaming raw material composition is cut along the cut surface in the longitudinal direction D1 and the width direction D2, and the thickness direction D3 of the panel 3 is produced and the foaming direction of the unit 31 is substantially Vertical (90°) panel 3 (dimension of longitudinal D1: 700 mm, dimension of width direction D2: 400 mm, dimension of thickness direction D3: 60 mm). The results are shown in Fig. 11.
