Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural structure such as a roof or an outer wall.

[0002]

2. Description of the Related Art In an architectural structure such as an outer wall or a roof, an exterior panel or the like is provided on a skeleton through a supporting member such as a rim material or a tile bar. At this time, the space formed between the exterior panel and the frame may have a function such as ventilation. The support member used here is generally formed of wood, synthetic resin, or the like. However, when the support member is formed of wood, the support member may be corroded by moisture or moisture entering the ventilation layer. Further, when the support member is formed of a synthetic resin, the support member does not allow moisture to pass therethrough, so that the mounting position is restricted to secure a drainage path, or moisture is retained for a long time by the ventilation layer so that the moisture is not absorbed. They move to the indoor side.

[0003]

Therefore, in the present invention,
An object is to provide a building structure having water permeability between an exterior member and a skeleton.

[0004]

According to the present invention, there is provided, in accordance with the present invention, an architectural structure comprising a skeleton, an exterior member, and a support member, wherein the exterior member includes the support member. A substrate portion attached to an exterior side of the skeleton while being supported by a member, the support member is fixed to the skeleton, and a substrate portion facing at least one of the skeleton and the exterior member; A plurality of partitioning portions projecting from the base portion, and a water channel is formed by the substrate portion and the partitioning portion, and the support member has a structure in which the substrate portion and the partitioning portion are made of synthetic resin with a substantially uniform thickness dimension. The present invention provides an architectural structure integrally formed by the above method.

[0005] In this architectural structure, since the water flow passage is formed in the support member in a state where the support member is attached to the frame, air and moisture can be circulated through the water flow passage of the support member. For this reason, this architectural structure has good air permeability and water permeability. In addition, the support member is formed of a synthetic resin or the like and thus has high water resistance. Since the substrate and the partition are formed to have a substantially uniform thickness, the strength in the thickness direction is high. Further, since deformation such as warpage or bending does not easily occur at the time of molding the support member, an architectural structure with less deviation can be obtained. In the present specification, “synthetic resin and the like” includes various polymer materials such as synthetic resin, rubber, and plastic.

Further, in the above-mentioned building structure, the water channel is formed in a hole having a square cross section, and the length of one side and the length of the other side are 1: 0.75. ~ 1.
An architectural structure formed in a ratio of 25 is provided. In this architectural structure, since the plurality of partitions are provided at predetermined intervals so that the cross section of the flowing water channel has a square shape or a shape similar thereto, the strength in the thickness direction of the support member is large. In addition, distortion such as warpage or bending of the support member after molding or in a construction state is unlikely to occur.

Alternatively, in the building structure, the substrate portion has at least two substrate portions along the frame and the exterior member, and the partition portion is provided between the two substrate portions. And a building structure formed in a corrugated shape. In this support member, a flowing water channel is formed by dividing the two substrate portions into a plurality by a corrugated partition portion. For this reason, a plurality of flowing water channels are formed at substantially equal intervals, warping of the support member after molding or in the construction state,
The occurrence of distortion such as bending is suppressed.

In any one of the above-mentioned architectural structures, the support member has two substrate portions and a plurality of partition portions provided between the two substrate portions. The thickness of the portion and the thickness of the partition portion are 5% or more and 15% or more of the thickness of the support member defined by the two substrate portions.
% Or less can be provided. When the thickness of the substrate portion and the partition portion of the support member is formed in the above-described ratio with respect to the thickness of the entire support member, the support member has water permeability and is a light support member having sufficient strength. In addition, it is possible to suppress distortion such as warpage or bending after the support member is formed or in a working state.

[0009] Further, there is provided the above-mentioned architectural structure, wherein an upper end of a portion of the support member abutting on the skeleton is inclined downward toward the exterior member side. In this architectural structure, the upper end of the substrate portion or the partition portion of the support member abutting on the skeleton is inclined downward toward the exterior member. For this reason, water does not accumulate in the thickness portion of the support member abutting on the skeleton, and there is no possibility that moisture will move inside the skeleton, that is, inside the room.

In any one of the above-mentioned building structures, the skeleton is a wall skeleton, and the support member is fixed to a stud provided on the wall skeleton so as to extend in a horizontal direction. The exterior member is an exterior wall material, and an architectural structure to which the fixing tool is attached by being penetrated from the exterior wall material to the substrate portion of the support member is provided. Alternatively, in any of the above building structures, the skeleton is a wall skeleton, and the support member is fixed so as to extend along a stud provided on the wall skeleton, and the exterior member Is an exterior wall material, and provides an architectural structure attached from the exterior wall material to which a fixing portion is attached by penetrating through the substrate portion of the support member.

In this wall structure, the supporting member favorably supports the exterior wall material as a horizontal frame material or a vertical frame material,
Water flow is provided by flowing water channels. For this reason, the water can move quickly in the direction of the flowing water channel, so that it is difficult for the water to move to the wall skeleton side, particularly to the attachment site. Further, the exterior wall material is fixed by, for example, a fixing tool such as a nail penetrating through the substrate portion of the support member, and thus has a strong force to support the exterior wall material.

On the other hand, the building structure may be a roof structure. That is, in any of the above-described building structures, the skeleton is a roof skeleton, and the support member extends horizontally to a base plate provided on the roof skeleton so that the support member extends horizontally. It is possible to provide an architectural structure attached by a fixing tool penetrating through the substrate portion, wherein the exterior member is a roofing material, and is attached by being locked to the support member. In this roof structure, since the support member is firmly fixed to the roof skeleton by the fixing tool penetrating through the substrate portion of the support member, the roof material such as a tile is locked to the support member, and It is kept stable. Also, rainwater or the like that has entered the inside of a roof material such as a tile can move downward from above through a through hole of the support member.

The skeleton 2 is a part constituting the main body of the building structure, and has a waterproof property on the outdoor surface. The skeleton 2 is a wall skeleton in the present embodiment, and has a plurality of columns 6 and studs 8 that form a frame or the like. Although not shown, a heat insulating material is filled between the pillars 6 and the studs 8 to form a heat insulating material layer, and various known members such as interior members are provided on the indoor side. As shown in FIG. 1, the pillars 6 extend from the base of the building or the like, and are provided at predetermined intervals between the corners and the plane portion of the wall structure 1. A plurality of studs 8 are provided at predetermined intervals between the pillars 6.

As shown in FIG. 1, waterproofness is provided by laying a waterproof sheet 9 on the outdoor side of the frame 2, that is, on the outdoor side of the columns 6 and the studs 8. The waterproof sheet 9 is a means for preventing water from flowing from the exterior side to the inside of the frame 2. Note that the waterproof sheet 9 may have a function as a windproof sheet. Further, for example, various waterproof sheets such as a type having airtightness, a type having air permeability only in one direction from the indoor side to the outdoor side, and a type having air permeability in both directions can be used.

The support member 10 is a long member fixed to the frame 2 and is an integrally formed body such as a synthetic resin.
In the present embodiment, the support member 10 is a horizontal frame member. As shown in FIG. 1, a plurality of support members 10 are provided at predetermined intervals so as to extend in the horizontal direction of the wall structure 1, and the exterior member 4 is attached via the support members 10.

FIG. 3 shows the support member 10. Support member 10
Is at least one substrate portion 12 (12a, 12b)
And a plurality of partition portions 14 formed to protrude from the substrate portion 12.

The substrate portion 12 is a flat plate portion provided so as to face at least one of the frame 2 and the exterior member 4 when fixed to the frame 2. As shown in FIG. 3, the support member 10 preferably has an inner substrate portion 12a closest to the outdoor surface of the frame 2 and an outer substrate portion 12b closest to the exterior member. With this configuration, the strength against the compressive force in the thickness direction applied to the support member 10 during construction or in an attached state is improved.

The partition part 14 is a part formed to protrude from the substrate part 12. The partition part 14 is typically
It is formed so as to protrude from at least two places of at least one substrate unit 12. The shape of the partition part 14 can be formed in a flat plate shape, a curved plate shape, a corrugated plate shape, or the like having a substantially uniform thickness.

The support member 10 of the present invention is formed such that the thickness of the substrate portion 12 and the thickness of the partition portion 14 are substantially equal to each other. By being formed in this way, when the support member 10 is integrally molded, the occurrence of distortion such as warpage or bending is favorably suppressed. The support member 10
Are the inner board part 12a and the outer board part 12b
In the case where the supporting member 10 is provided, it is preferable that the thickness of the substrate portions 12a and 12b and each of the partitioning portions 14 be 5% or more and 15% or less with respect to the thickness of the supporting member 10. Here, the thickness of the support member 10 refers to the inner substrate portion 12a and the outer substrate portion 12b.
And the thickness is defined as In the present embodiment, the thickness is from the outer surface of the inner substrate portion 12a to the outer surface of the outer substrate portion 12b. When formed in this ratio, it is easy to suppress the occurrence of distortion during molding, and it is possible to increase the strength of the support member against the compressive force in the thickness direction.

The space defined by the substrate section 12 and the partition section 14 is formed in a flowing water channel 16. The water channel 16 is a hole-like space or a groove-like space, and is formed so that water can flow down in a state where the support member 10 is fixed to the structure. Since the support member 10 of FIG. 3 is used as a lateral frame material, a plurality of flowing water passages 16 are formed that penetrate in a direction substantially perpendicular to the longitudinal direction of the support member 10 formed in a long shape. The flow channels 16 are preferably formed with equal cross-sectional shapes. Also, more preferably, the water passages 16 are formed in equal cross-sectional shapes, and are arranged at equal intervals. Specifically, the cross section of the flowing water channel 16 is formed in a square shape, a triangular shape, or the like. Preferably, it is formed in a square or equilateral triangle. In other words, the partition portions 14 are preferably formed so as to protrude from the substrate portion 12 in a similar or symmetrical shape to each other, and more preferably have the same shape. Further, it is preferable that the partition portions 14 are arranged on the substrate portion 12 at equal intervals.

For example, as shown in FIG. 3, a plurality of partition portions 14 are provided between the two substrate portions 12a and 12b.
By forming it perpendicular to 2a and 12b, a square water channel 16 can be formed. Here, the square shape means that the length in the thickness direction of the partition part 14 and the interval at which the partition part 14 is provided, that is, the ratio of the length of one opposite side to the other opposite side of the flowing water channel 16 is 1: 0. 75-1.
Say 25. When formed in this manner, the occurrence of distortion such as warpage or bending after the support member 10 is integrally formed is suppressed, straightness is favorably maintained, and the compressive strength of the support member 10 in the thickness direction is increased.

Further, like the support member 30 shown in FIG. 4B, the partition part 24 is formed in a corrugated plate shape, and a hole-shaped flowing water channel formed by the substrate part 22a or 22b and the partition part 24. 26 can be formed in an equilateral triangle shape. Also in this case, similarly to the case of FIG. 3, distortion such as warpage or bending after integral molding is well suppressed, and the compressive strength in the thickness direction of the support member 20 is increased. The equilateral triangle shape is
Regardless of the shape of each vertex or the length of each side, it refers to a triangular shape whose appearance looks like an equilateral triangle.

Alternatively, as shown in a supporting member 20 shown in FIG. 4A, an intermediate substrate portion 12c is provided between the inner substrate portion 12a and the outer substrate portion 12b, and between the substrate portions 12a, 12c and the substrate portion 12c. , 12b, a plurality of partitions 14 may be formed at equal intervals. Also in this case, the flowing water channel 16 formed by the substrate portions 12a to 12c and the partition portion 14 is provided.
Is preferably formed in a square cross section. In addition,
A plurality of intermediate board parts 12c may be provided. further,
As shown in a supporting member 40 shown in FIG. 4C, only one substrate portion 32 constituting either the inside or the outside is provided, and a plurality of partition portions 34 are formed at equal intervals from the substrate portion 32. Is also good. Also in this case, it is preferable that the flowing water channel 36 is formed in a square cross section.

The end of the supporting member 10 through which the water flow passage 16 penetrates, as shown in FIGS.
a, 12b can be formed on an end surface that is inclined from a direction perpendicular to the direction. When formed in this manner, the support member 1
The upper end surface of the portion that comes into contact with the 0 skeleton 2 is formed so as to be inclined down to the exterior member 4 side.

The support member 10 is fixed to the frame 2 by various methods so that the water passage 16 penetrates in a direction in which water can flow down. As shown in FIG. 2, when the support member 10 is fixed to the stud 8, the support member 10 is stably fixed. Further, it may be fixed to a member such as a pillar 6 which constitutes a shaft assembly. As shown in FIG. 2, the support member 10 includes a support member 10 such as a nail, a screw, a tucker, or the like.
It is preferable that the fixing member 17 is fixed to the skeleton 2 by the fixing member 17 which can penetrate the substrate portion. In the present embodiment, the support member 10 is fixed with a nail 17 so as to extend in the horizontal direction with respect to the frame 2. At this time, running water channel 1
6 penetrates in the vertical direction, that is, in the direction of gravity. In addition, as shown in FIG. 2, the support member 10 is fixed so that the uppermost end of the end face in the penetrating direction of the flowing water channel 16 formed obliquely contacts the frame 2 side.

The exterior member 4 is a part constituting the exterior of the building structure. In the present embodiment, the exterior member 4 is
It is a thin plate-like exterior wall material composed of an exterior panel and its base material. As shown in FIG. 2, the exterior member 4 is fixed to the skeleton 2 so as to be supported by the support member 10. Various methods can be used to attach the exterior member 4, such as nails, screws, and tackers 19, which can penetrate the exterior member 4 and the substrate portion of the support member 10, as shown in the figure.
Is preferably fixed because it is firmly fixed.

The wall structure 1 comprises a frame 2 and an exterior member 4.
A space for ventilation is formed between them. A running water passage 16 is provided in the support member 10 that crosses the ventilation space. For this reason, air and water can flow over the whole vertical direction of the wall structure 1, and favorable air permeability and water permeability are ensured.

Therefore, even when rainwater or the like enters,
Moisture flows down from the top to the bottom through the ventilation space through the flowing water channel 16, so that the moisture does not remain. For this reason, the stud 8, the fixing members 17, 19, the exterior member 4, the frame 2
Hard to corrode inside. Since the support member 10 is formed of a synthetic resin or the like, there is no possibility of corrosion. Also, even when moisture moves from the indoor side or when moisture and humidity increase due to dew condensation due to a temperature difference between the room and the outside, air and humidity move through the ventilation space, so that a good dry state is maintained. can do. For this reason, it is suppressed that moisture accumulates in the heat insulating material layer in the skeleton 2 and the function is reduced, or that moisture moves to the indoor side.

As shown in FIG. 2, since the upper end of the portion of the support member 10 (substrate portion 12a) abutting on the frame 2 is inclined downward toward the exterior member 4, the support member 10 is directed downward from above. The flowing water does not accumulate at the upper end of the support member 10 and flows down smoothly. For this reason, the period during which moisture contacts the skeleton 2 is short, and the penetration of moisture into the interior of the skeleton 2 is favorably suppressed. Further, accumulation of moisture and accumulation of moisture are suppressed.

The shape in which the upper end of the portion of the support member 10 abutting on the frame 2 is inclined downward toward the exterior member 4 is such that only the thickness portion of the substrate portion 12a is moved toward the exterior member 4 (flow water channel 16). It can also be obtained by forming it on a surface inclined downward. The support member 10 contacting the frame 2 is formed by forming the upper end of the support member 10 in contact with the frame 2, that is, the upper surface of the inner substrate portion 12 a or the partition 14 downward toward the exterior member 4 side. The shape is such that water does not collect at the upper end of the. Similarly, the portion of the support member 10 that comes into contact with the exterior member 4 has a shape that is inclined downward toward the skeleton 2 (flow channel 16), so that the portion of the support member 10 that comes into contact with the exterior member 4 is formed. Water can be prevented from being accumulated, and accumulation of moisture can be suppressed.

Here, a method for manufacturing the support member of the present invention will be described. The support member is made of a synthetic resin or the like, that is, various polymer materials such as plastic or rubber. Preferably, when the support member 10 is formed of a material containing a hard polyolefin resin, the rigidity and toughness of the support member 10 increase. In this case, when the fixing member 17 such as a nail penetrates through the substrate portion of the support member 10, the support member 10 is prevented from being cracked or torn and broken. More preferably, a resin material containing a polypropylene resin as a main component is used.

The support member 10 is preferably formed by integral molding, and can be formed by injection molding or extrusion molding. When integrally molded with synthetic resin, rubber, or the like, the water channel 16 can be formed simultaneously with molding. More preferably, when it is formed by extrusion, it is easy to form it into a length commensurate with the size of the building structure.

For example, as shown in FIG. 5, it is preferable to form the support member 11 provided with the flowing water channel 16 by extrusion and then to separate the support member by cutting or the like in a predetermined direction. In this method, the flowing direction of the water passage 16 with respect to the shape of the support member 10 is determined by the support member raw material 1.
It is determined by the direction that separates one. For example, when separated in a direction perpendicular to the extrusion direction of extrusion (the X direction in FIG. 5), as shown in FIG. 3, a support provided with a flowing water channel penetrating in a direction perpendicular to the longitudinal direction of the support member. The component is manufactured. When separated in a direction parallel to the extrusion direction of extrusion (Y direction in FIG. 5), as shown in FIG. 8 described later, a support member having a flowing water passage penetrating in a direction parallel to the longitudinal direction of the support member is provided. Is manufactured.

The separating direction of the support member raw material 11 is not limited to the direction perpendicular or parallel to the extrusion direction of the extrusion molding, and may be cut diagonally. Even in this case,
The flowing water channel 16 is penetrated from one side of the support member 10 to the other side, and has a configuration capable of flowing water.

Further, by cutting the supporting member raw material 11 such that the end face through which the flowing water passage 16 penetrates with respect to the surface forming the substrate portion 12 forms an acute angle, the thickness portion of the substrate portion 12 is flushed from the outer surface. It can be formed into a shape that enters the road side. According to this method, the support member can be easily formed into a shape in which the support member is formed from the raw support member and the upper end of the portion that contacts the frame of the substrate portion 12 is inclined downward toward the exterior member. Further, it is preferable because there is no waste of material as in the case of cutting.

In this manufacturing method, a support member having a flowing water channel and formed in a predetermined shape can be obtained only by the forming step and the cutting step. For this reason, there is no need to form a flowing water channel in a separate step, and the number of manufacturing steps is small, and the amount of wasted raw materials can be suppressed to manufacture the support member. For this reason, a low-cost supporting member having water permeability and water resistance can be manufactured. In addition, since a support member having a predetermined shape can be obtained by forming a plate-shaped raw material of a support member and cutting the same into a predetermined size, a large number of support members can be manufactured by one molding, or a plurality of support members can be manufactured. For example, a support member having a shape can be manufactured.

Next, a wall structure according to a second embodiment of the present invention will be described. FIG. 6 shows a wall structure 50,
FIG. 7 shows a cross section thereof. The wall structure 50 includes the wall structure 5.
2, a support member (vertical frame material) 60 is fixed to the outside of the room, and an exterior member 54 is provided outside the support member. Note that the wall frame 52 and the exterior member 54 are the same as the wall frame 2 and the exterior member 4 of the first embodiment, respectively, and a detailed description thereof will be omitted.

As shown in FIG. 8, the support member 60 has an inner substrate 62a, an outer substrate 62b, and a plurality of partitions 64. In the support member 60, the partition 64
Are formed so as to extend in parallel with the longitudinal direction of the support member 60. The water passage 66 formed by the substrate portions 62a and 62b and the adjacent partition portion 64 is formed to extend in the longitudinal direction of the support member 60, and has a square cross section. Further, as shown in FIG.
The end of the support member 60 can be formed on an inclined surface such that the end surface of “a” is inclined downward toward the flowing water channel 66.

The support member 60 can be fixed to the frame 52 with a fixing member 57 penetrating the substrate portion of the support member 60. The support member 60 is fixed to the skeleton 52 such that the water passage 66 penetrates in a substantially vertical direction (gravity direction). 6 and 7
As shown in FIG.
And extending along each stud 58,
It has the same configuration as the vertical frame material. Further, similarly to the exterior member 4, the exterior member 54 also includes the substrate portion 6 of the support member 60.
The frame 52 is fixed by the fixing tool 59 penetrated through the 2a and 62b.
Attached to the side.

In the wall structure 50, the exterior member 54 is attached to the frame 52 so as to be supported by the support member 60, and a ventilation space is formed between the exterior member 54 and the frame 52. . A running water channel 66 is formed in the support member 60 that passes through the ventilation space. For this reason, similarly to the wall structure 1 of the first embodiment, good ventilation and water permeability are ensured over the entire vertical direction of the wall structure 50. In addition, since the upper end of the portion of the support member 60 that contacts the skeleton 52 is inclined downward toward the exterior member 54, moisture does not accumulate at the upper end of the support member 60, and the moisture smoothly flows from top to bottom. Run down. For this reason, the period during which moisture contacts the skeleton 2 is short, and the penetration of moisture into the interior of the skeleton 2 is favorably suppressed.

The support member 80 may be attached to the field board 78, or may be fixed by a fastener 77 that passes to the rafter 76 as shown in FIG. The support member 80 is fixed to the outdoor surface of the roof frame 72 so as to extend in the horizontal direction, and is provided so that the water passage 86 penetrates from the upper side to the lower side along the roof surface.

As shown in FIG. 10, a plurality of support members 80 are provided at predetermined intervals in the vertical direction along the roof surface so as to extend over the entire roof frame 72 in the horizontal direction. When the length of the support member 80 is less than the horizontal length of the roof skeleton 72, the support members 80 can be mounted on the roof skeleton 72 in a connected manner by abutting the side ends of the support member 80.

In the present embodiment, the exterior member 74 is formed as shown in FIG.
As shown in the figure, the projection 75a formed on the upper end of the roof tile 7 is attached to the upper end of the support member 80 by being locked.
