Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction structure for sandwiching a panel between a plurality of longitudinal members arranged in parallel and a manufacturing method thereof.

There has been known a building structure including a plurality of longitudinal members (for example, pillars or the like) and a rigid panel sandwiched between the longitudinal members so as to be parallel to each other in the longitudinal direction For example, Patent Document 1). For example, the panel is a heat insulating material made of a synthetic resin.

In such an architectural structure, high precision of the panel dimensions is required. Specifically, when the dimension of the panel is small, a clearance is generated between the panel and the longitudinal member. On the contrary, when the dimension of the panel is small, the panel is not sandwiched between the longitudinal members or the panel which is forcibly fitted is damaged.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a building structure and a method of manufacturing the same that can easily fit the panel between the longitudinal members and prevent a gap from being generated between the panel and the longitudinal member, .

The building structure according to the present invention includes a plurality of length members arranged in parallel in a second direction orthogonal to the first direction so that the longitudinal direction of the building members is parallel to the first direction, and a panel sandwiched between the length members, The panel 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.

According to the construction structure of the present invention, the plurality of length members are arranged in parallel in a second direction orthogonal to the first direction so that the longitudinal direction of each of the plurality of length members is parallel to the first direction. The panel is resilient in the second direction because it is a foam having a plurality of cells elongated along a direction orthogonal to the second direction. Thus, the panel, which is compressed in the second direction, is decompressed and restored between the longitudinal members (or the panel is compressed between the longitudinal members while being compressed in the second direction) so that the panel is in close contact with the longitudinal members, And is sandwiched between the longitudinal members in a pressed state.

In the building structure according to the present invention, the plurality of cells may be elongated along the first direction so that the elastic modulus of the panel in the second direction is smaller than the elastic modulus of the panel in the first direction.

According to this configuration, since the plurality of cells are formed along the direction orthogonal to the second direction, the modulus of elasticity in the second direction of the panel is reduced. Thereby, since the panel has elasticity in the second direction, the panel is liable to be compressed in the second direction. Furthermore, since the plurality of cells are formed along the first direction in the direction orthogonal to the second direction, the modulus of elasticity of the panel in the first direction is increased. Whereby the panel sandwiched between the elongated members is stably held between the elongated members because the panel has rigidity in the first direction.

A method of manufacturing a building structure according to the present invention is characterized in that the plurality of length members are arranged in a second direction orthogonal to the first direction so that their longitudinal directions are parallel to the first direction, A panel that is a foam having a plurality of cells formed along a direction orthogonal to the second direction is sandwiched between the length members.

INDUSTRIAL APPLICABILITY As described above, the present invention has an excellent effect that it is possible to easily insert the panel between the longitudinal members and to prevent a gap from being generated between the panel and the longitudinal members.

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

As shown in Figs. 1 and 2, the building structure 1 according to the present embodiment has a plurality of (two shown in Figs. 1 and 2) lengths arranged in parallel in the width direction so that their longitudinal directions are parallel to each other (2), and a panel (3) sandwiched between the longitudinal members (2, 2). The building structure 1 is provided with frame members 4 and 4 fixed to the end portions of the elongated member 2 and a plate member 5 fixed to the side portions of the elongated member 2. [ In the present embodiment, the building structure 1 is a wall.

The length member 2 has support surfaces 21, 21 for supporting the panel 3 on both sides in the width direction. Specifically, the cross-sectional shape of the elongated member 2 is rectangular. The plurality of length members 2 are arranged so that the support surfaces 21 face each other. In the present embodiment, the elongated member 2 is a column, and its longitudinal direction is arranged parallel to the height direction.

The panel 3 is formed in a rectangular parallelepiped shape. The longitudinal direction of the panel 3 and the longitudinal direction of the longitudinal member 2 are parallel to each other in the state where the panel 3 is sandwiched between the longitudinal members 2 and 2, Are parallel to each other.

In the present invention, the direction parallel to the longitudinal direction of the longitudinal member 2 is referred to as a first direction D1 of each of the building structure 1, the longitudinal member 2 and the panel 3, The direction parallel to the parallel direction is referred to as a second direction D2 of the building structure 1, the elongated member 2 and the panel 3 respectively and is orthogonal to the first direction D1 and the second direction D2. Direction is referred to as a third direction D3 of the building structure 1, the longitudinal member 2 and the panel 3, respectively.

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

The panel 3 is a foam formed of a synthetic resin (for example, a urethane resin, a styrene resin, a phenol resin, or the like) and having elasticity, as shown in Figs. Specifically, the panel 3 is a foam having a plurality of cells 31 elongated 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 that all the cells 31 are formed long along the direction perpendicular to the second direction D2. For example, in order to have the elasticity of the panel 3 in the second direction D2, At least half of the cells 31 may be formed long along the direction orthogonal to the second direction D2. That is, in the present invention, if the panel 3 has elasticity in the second direction D2, the cell 31 may be provided along the direction parallel to the second direction D2.

The panel 3 is formed such that the modulus of elasticity in the width direction D2 is smaller than the modulus of elasticity in the longitudinal direction D1. The panel 3 is formed such that the modulus of elasticity in the width direction D2 and the modulus of elasticity in the thickness direction D3 are substantially equal to each other.

The panel 3 is formed such that the plurality of cells 31 are elongated along the longitudinal direction D1 of the direction orthogonal to the width direction D2 so that the elastic modulus in the width direction D2 is greater than the elastic modulus in the longitudinal direction D1, Is smaller than the elastic modulus of elasticity. More specifically, since the plurality of cells 31 are arranged along the longitudinal direction D1 with the longest dimension, the modulus of elasticity in the width direction D2 and the thickness direction D3 of the panel 3 is greater in the longitudinal direction (D1).

The elastic modulus is a ratio of stress and distortion (deformation amount) in the elastic range in the case of deforming the panel 3 by applying an external force. In other words, the smaller the modulus of elasticity, the larger the amount of deformation to the same stress (pressure).

Since the dimension W2 of the width direction D2 of the panel 3 which is not elastically deformed is larger than the spacing distance W1 of the length members 2 and 2, And is sandwiched between the longitudinal members 2, The dimension W2 of the panel 3 in the width direction D2 which is not elastically deformed is preferably 101% to 115% of the spacing distance W1 of the length members 2 and 2, and preferably 105% to 110% Is more preferable.

In the present 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 polyisocyanate component with a polyol compound containing water as a foaming agent and a polyisocyanate component and has a longitudinal direction D1, a width direction D2 and a thickness direction D3 the ratio of polyurethane foam and a panel foam density of 15kg / ㎥ or less vertical direction (D1) 10% compressive strength (S _D1) and 10% compressive strength (S _D2) in the transverse direction (D2) of (S _D1 / S _D2 ) 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 a foam density is set within the above range, for example, by adjusting the amount of water as the foaming agent to 20 to 100 parts by weight (100 parts by weight of the large polyol compound). Here, the foam density is a value measured in accordance with 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 elongated in the longitudinal direction D1 and formed into an elliptical shape. The longitudinal direction D1 of the panel 3 becomes parallel to the longitudinal direction D1 of the elliptical cell 31 so that the foam strength in the longitudinal direction D1 of the panel 3 increases. The foam strength in the thickness direction D2 and the thickness direction D3 is lowered and the width direction D2 and the thickness direction D3 of the panel 3 have elasticity.

The panel 3 is formed such that two or more non-(S _D1 / S _D2) in the longitudinal direction of 10% compressive strength (S _D1) and 10% compressive strength (S _D2) in the transverse direction (D2) of (D1) have. 10% compressive strength (S _D1 ) in the longitudinal direction D1 and 10 (10) compressive strength in the width direction D2 in order to achieve both the work of sandwiching the panel 3 between the elongated members 2 and the self- (S _D1 / S _D2 ) of the percent compressive strength (S _D2 ) is preferably 3 or more, and more preferably 5 or more. The upper limit of this ratio (S _D1 / S _D2 ) is not particularly limited, but is, for example, about 7. The X% compressive strength is a stress required to compressively deform the panel 3 by an amount of X%.

It is necessary to be able to easily compress the panel 3 in the width direction D2 in order to improve workability of sandwiching the panel 3 between the elongated members 2, Thus, the panel 3 is 10% compressive strength (S _D2) is less than or equal to 3N / ㎠ in the transverse direction (D2) is preferred, more preferably not more than 1N / ㎠ of, to 0.5N / ㎠ or less is particularly preferred.

It is also necessary that the compressed panel 3 be quickly restored in order to improve workability of sandwiching the panel 3 between the elongated members 2, Therefore, even when the panel 3 is compressed by 20% in the width direction D2, it is not damaged or broken. Further, when the panel 3 is opened after being compressed by 20% in the width direction D2, Or more.

It is preferable that the panel 3 is formed such that the foaming direction of the cell 31 is substantially perpendicular to the width direction D2 and the thickness direction D3, respectively. The term " substantially perpendicular " means specifically 90 DEG +/- 15 DEG, and particularly 90 DEG +/- 10 DEG. (The direction D1) of the width direction D2 of the panel 3 and the width direction D2 of the panel 3 in the longitudinal direction D1, And a portion of about 10% on both sides of the dimension in the longitudinal direction D1 and the dimension in the width direction D2 from the center in the width direction D2).

Since the panel 3 is used as a heat insulating material, the thermal conductivity lambda of the panel 3 is preferably 0.04 W / mK or less. As a result, sufficient heat insulation performance can be exhibited even with the panel 3 having a low density. 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%. By thus increasing the degree of communication, excellent dimensional stability can be ensured. Here, the closed cell ratio is a value measured in accordance with ASTM D2856.

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

A flame retardant, a catalyst and a foam stabilizer are usually added to the polyol composition. In addition, various additives such as a coloring agent and an antioxidant may be further added to the polyol composition.

Examples of the flame retardant include organic phosphoric acid esters, halogen-containing compounds, and metal compounds such as aluminum hydroxide, and organic phosphoric acid esters are particularly preferable because they have a viscosity-lowering effect of the polyol composition. Examples of the organic phosphoric acid ester include halogenated alkyl esters of phosphoric acid, alkyl phosphoric acid esters, aryl phosphoric acid esters, and phosphonic acid esters. Specific examples thereof include tris (chloropropyl) phosphate (TMCPP, manufactured by Daihachi Chemical), tributoxyethyl phosphate (TBEP), tributyl phosphate, triethyl phosphate, trimethyl phosphate and cresyldiphenyl phosphate. The blending amount of the flame retardant is preferably 10 to 50 parts by weight, more preferably 15 to 40 parts by weight, based on 100 parts by weight of the polyol compound. Particularly, it is preferable that the polyol composition contains 20 parts by weight or more of a flame retardant in addition to the polyether polyol (A) and the short glycol (B) in 100 parts by weight of the polyol compound in order to prevent the brittleness deterioration of the foam.

The lower limit of the isocyanate index is, for example, 20. By making the isocyanate index fall within the above range, a polyurethane foam panel 3 having a low density and having particularly excellent elasticity and heat insulating performance can be obtained. Here, the isocyanate index means the ratio of the equivalent ratio of the isocyanate group of the polyisocyanate component to the total active hydrogen group contained in the polyol composition (water as a foaming agent is calculated as a bifunctional active hydrogen compound) as a percentage Equivalent ratio of isocyanate group).

The method for producing the panel 3 is a method for producing a polyurethane foam panel 3 obtained by using as a raw material a polyol compound, a polyol composition containing water as a foaming agent, and a foamed stock solution composition containing a polyisocyanate component, For example, when the polyol composition contains a polyether polyol (A) having an average number of functional groups of 2 to 4 and a weight average molecular weight of 3000 to 8000 as a polymer of an alkylene oxide and a polyol compound containing a short glycol (B) having a molecular weight of less than 250 And 20 to 100 parts by weight of water with respect to 100 parts by weight of the polyol compound, it is preferable that the isocyanate index when the polyol composition and the polyisocyanate component are mixed and reacted is less than 30.

In the reaction step, the mold 7 may be warmed as a whole or locally as necessary.

The construction of the building structure 1 according to the present embodiment is as described above. Next, a manufacturing method of the building structure 1 according to the present embodiment will be described below with reference to Fig.

As shown in Fig. 6, the plurality of length members 2, 2 are arranged in parallel in the width direction D2 such that the longitudinal direction D1 is parallel. An external force is applied to the panel 3 so that the panel 3 is compressed in the width direction D2. The dimension W2 in the width direction D2 of the panel 3 larger than the spacing distance W1 of the length members 2 and 2 is smaller than the spacing distance W1 of the length members 2 and 2 .

After the panel 3 compressed in the width direction D2 is positioned between the elongated members 2 and 2, the applied external force is released and the panel 3 is restored. Since the panel 3 is further restored by the elastic force even after it abuts against the support surface 21 of the elongated member 2, the elongated member 2 is pressed against the elongated member 2 in a state of being pressed against the elongated member 2, 2, 2).

As described above, according to the building structure 1 of the present embodiment, the plurality of the longitudinal members 2 are arranged in the second direction (vertical direction) perpendicular to the first direction D1 so that the longitudinal direction of each of the longitudinal members 2 is parallel to the first direction D1 D2.

According to the building structure 1 of the present embodiment, since the plurality of cells 31 are elongated along the direction orthogonal to the second direction D2, the number of the cells 31 in the second direction D2 The modulus of elasticity is reduced. Thus, since the panel 3 has elasticity in the second direction D2, the panel 3 is liable to be compressed in the second direction D2.

Furthermore, since the plurality of cells 31 are elongated along the first direction D1 in the direction orthogonal to the second direction D2, the modulus of elasticity of the panel 3 in the first direction D1 becomes large. The panel 3 sandwiched between the longitudinal members 2 and 2 is stably held between the longitudinal members 2 and 2 because the panel 3 has rigidity in the first direction D1. As a result, the panel 3 can stand alone.

In addition, since the plurality of cells 31 are elongated 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 It is possible.

As a result, since the panel 3 has rigidity in the first direction D1, the panel 3 sandwiched between the longitudinal members 2, 2 can stand alone, .

In the building structure 1 shown in Fig. 8, the adjacent panel end portions 32 and 32 abut against each other at positions deviated from each other between the longitudinal members 2 and 2, and the panel end portions 33 and 33 on the opposite side abut each other Is located between the elongated members 2 and 2 and abuts against the elongated member 2 and the plate member 5. The panel 3 receives the external force such that the adjacent panel end portions 32 and 32 are positioned between the longitudinal members 2 and 2 so that the panel 3 is compressed in the second direction D2, , 2).

In the building structure 1 according to the embodiment, the panel 3 is formed such that the dimension in the first direction D1 is larger than the dimension in the second direction D2.

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 this configuration. For example, in the present invention, the panel 3 may be cut in a rectangular parallelepiped shape such that the foamed undiluted solution composition is spread on the conveyor and the vertical direction is the first direction D1.

9, the panel 3 may have a tapered portion 34 inclined at an end thereof in the second direction D2 with respect to the third direction D3, as shown in Fig. The panel 3 is formed by the tapered portion 34 such that the dimension in the second direction D2 gradually increases. Such a panel 3 is pressed in the third direction D3 and is sandwiched between the longitudinal members 2 and 2 while being compressed in the second direction D2. The tapered portion 34 may be provided only at one end of the panel 3.

10, a stop 6 for stopping the panel 3 sandwiched between the longitudinal members 2, 2 while protruding in the second direction D2 from the longitudinal member 2 It may be configured to be installed. The stop portion 6 includes an engagement portion 61 for engaging the panel 3 sandwiched between the elongated members 2 and 2 in the second direction D2 and an inclined portion 61 inclined with respect to the third direction D3 (62).

With such a configuration, the panel 3 is compressed in the second direction D2 by the inclined portion 62 of the stopper 6 by being pressed in the third direction D3. The panel (3) is sandwiched between the longitudinal members (2, 2) by passing over the stop (6). The panel 3 sandwiched between the elongated members 2 and 2 is prevented from coming out from between the elongated members 2 and 2 because it is caught by the stopper 6.

In the present invention, the panel 3 may be covered with a film (for example, a shrink film made of vinyl or the like) on its surface. According to this configuration, the panel 3 can be easily handled when the operator has the panel 3 or when the plurality of panels 3 are piled up.
