Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall construction structure in which a plurality of ceramic outer panels are fixed to a structural body of a building by a framed wall method, a framed wall method or the like to form a bearing wall.

[0002]

2. Description of the Related Art Conventionally, as an outer wall construction structure of a building board, there is an outer wall construction structure constructed by a framed wall construction method, a framed wall construction method or the like. As the above-mentioned conventional outer wall construction structure 9, there is one shown in FIG.

That is, the outer wall construction structure 9 is a structural body 9 of a building composed of a skeleton member 921 made of wood or the like.
2 and a plurality of structural face materials 9 fixed to the structural frame 92.
3, a waterproof sheet 94 covering the structural face material 93, a body edge 95 fixed to the structural face material 93 via the waterproof sheet 94, and a plurality of ceramics systems attached to the body edge 95. It comprises an outer wall plate 96 (FIGS. 16 and 17). The above structural frame 92
The structural face material 93 fixed to the wall constitutes a load-bearing wall 930 for securing the strength of the building against an applied mechanical load.

When the outer wall construction structure 9 is constructed, firstly, the skeleton member 921 is used to construct the structural frame 92.
Assemble. Next, the plurality of structural face members 93 are fixed to the skeleton member 921 by hitting a nail 935. Thus, a bearing wall 930 in which the structural face material 93 is fixed to the structural skeleton 92 is formed. Further, the structural surface material 93
Then, a body edge 95 is fixed via the waterproof sheet 94, and a plurality of ceramic outer wall plates 96 are sequentially attached to the body edge 95. If necessary, a coating material is applied to the front surface of the ceramic outer wall plate 96. Thus, the outer wall construction structure 9 is obtained.

[0005]

However, the above-mentioned conventional outer wall construction structure 9 has the following problems. That is, the outer wall construction structure 9 is, as described above, the structural body 92,
It is composed of a structural surface material 93, a waterproof sheet 94, a rim 95, and a ceramic outer wall plate 96, and has many components and a complicated structure (FIGS. 16 and 17). Therefore, the outer wall construction structure 9
Construction requires a large number of man-hours and also increases material costs. Further, since the outer wall construction structure 9 has a large thickness excluding the structural skeleton, there is also a problem that the effective indoor space is narrowed.

Also, the ceramic outer wall plate 96 is attached to the body edge 95.
It is also conceivable to nail and fix directly to the structural body 92 via the above. However, since the ceramic outer panel 96 does not particularly have impact resistance, when it is nailed to this,
As shown in FIG. 18, cracks 966 and chips 967 are likely to occur around the penetrating portion of the nail 935 on the back side surface 961. Thereby, there is a possibility that the fixing force of the ceramic outer wall plate 96 to the structural frame 92 may be reduced.

In the outer wall construction structure 9, since the waterproof sheet 94 is provided, it is possible to prevent water from infiltrating into the interior of the building (arrow B in FIG. 17). Water absorption from the back surface 961 of itself cannot be prevented. Therefore, conventionally, the rear side surface 96 of the ceramic outer wall plate 96 has been described.
Although a means for applying a sealer treatment is employed in 1, the waterproofing effect is also insufficient by this, and there is a possibility that water is absorbed particularly from the cracks 966 and chips 967. Due to the water absorption, the ceramic outer wall plate 96 may change its dimensions. Further, the above-mentioned crack 966
When carbon dioxide invades from the portion of the chip 967 or the like, carbonation and neutralization of the ceramic outer panel 96 due to aging are promoted, and there is a possibility that the durability may be deteriorated.

Further, the ceramic outer wall plate 96 is attached to the structural frame 9.
2 directly, there is a problem that it is difficult to prevent dew condensation on the indoor side wall of the ceramic outer wall plate 96, the structural frame 92, and the like. That is, as shown in FIG. 21A, when the ceramic outer wall plate 96 is directly fixed to the structural frame 92, the heat insulating material 9 is placed on the indoor side of the ceramic outer wall plate 96.
8 is installed. Then, particularly in winter, the high-temperature and high-humidity air 7 in the room passes through the heat insulating material 98 and reaches the inside of the ceramic outer wall plate 96. Since the temperature near the ceramic outer wall plate 96 is close to the temperature of the outside air, the temperature is low in winter and the like. Therefore, the high-temperature and high-humidity air 7 passing through the heat insulating material 98 from the room is cooled, and the ceramic-based outer wall plate 9 is cooled.
Dew condensation occurs on the inner surface of the inner surface 6, the heat insulating material 98, or the surface of the structural body 96.

Here, as shown in FIG. 17, in the case of a structure in which a structural face material 93 is fixed to the structural frame 92 and a ceramic outer wall plate 96 is further constructed via a rim 95, The ventilation layer 9 is provided between the face material 93 and the ceramic outer wall plate 96.
7 can be provided (FIG. 20). That is, the ventilation layer 9
7 is provided as follows. That is, the ceramic outer wall plate 96
19A, the above-mentioned rim 95 is constructed in the vertical direction as shown in FIG. 19 (A). When the ceramic outer wall plate 96 is constructed in the vertical direction, as shown in FIG. 19 (B). A cut 951 is provided in the torso 95 and is constructed in the lateral direction.

As a result, it is possible to form the ventilation layer 97 through which the air 7 between the ceramic outer wall plate 96 and the structural face material 93 can reliably escape upward. Therefore, as shown in FIG. 20, the air 7 passes through the ventilation layer 97, thereby preventing the above-described dew condensation. In addition,
In FIGS. 19A and 19B, reference numeral 928 denotes a window frame.

However, as described above, the structural frame 92
When the ceramic outer wall plate 96 is directly fixed to the
In (A)), the ventilation layer 97 cannot be provided. In particular, the barrel insert 924 in the structural frame 92 is
Since the left and right through pillars 923 are connected as shown in FIG. 21B, the passage through which the high-temperature and high-humidity air 7 escapes is blocked (FIG. 21A).

For this reason, the ceramic outer wall plate 96 and the heat insulating material 9
8. There is a risk of dew condensation on the structural frame 92. As a result, the durability of the load-bearing wall may be degraded due to the corrosion of the structural frame 92, or the heat insulation performance may be degraded due to the swelling of the heat insulating material 98. Further, the permeation of moisture into the ceramic outer wall plate 96 causes the durability of the plate itself to gradually deteriorate. Further, when the structural frame is made of wood, it may cause corrosion of the wood.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is intended to provide a bearing wall having excellent workability, waterproofness, and durability, and to provide an outer wall construction structure having excellent air permeability. Things.

[0014]

According to the first aspect of the present invention, there is provided an outer wall construction structure comprising a load-bearing wall formed by fixing a plurality of ceramic outer panels to a structural body of a building. The ceramic outer panel is lined with a resin sheet on the back side, and a waterproof tape is interposed between the rear side and the structural frame at the peripheral end of the ceramic outer panel, and An outer wall construction structure is characterized in that a cutout groove for ventilation is formed in a contact face with the ceramic outer wall plate on a side wall constituting the structural frame to vertically penetrate therethrough.

The most remarkable point of the present invention is that the ceramic outer wall plate is lined with a resin sheet on the back surface, and the waterproofing is provided between the back side surface and the structural frame at the peripheral end of the ceramic outer wall plate. A tape is interposed, and a cutout groove for ventilation is formed in the trunk. The notch groove is formed in a vertical direction in a state where the body insertion is assembled as a skeleton of a structural body.
That is, the notch groove is formed in a direction perpendicular to the length direction of the barrel insertion. A plurality of the notch grooves may be formed around the width of one ceramic outer wall plate.
It may be formed individually.

Examples of the ceramic outer wall board include a hard wood chip cement board, a magnesium carbonate board, a wood fiber mixed cement board, a pulp mixed cement board and the like. Examples of the resin sheet include a polyethylene sheet, a foamed polyethylene sheet, a polyethylene terephthalate sheet,
There are vinyl chloride sheets and vinylidene chloride sheets. Alternatively, as the resin sheet, for example, a foamed polyethylene sheet and a polyethylene terephthalate sheet are laminated, a foamed polyethylene sheet and a paper nonwoven fabric or a polyethylene terephthalate nonwoven fabric are laminated, or a polyethylene sheet and a paper nonwoven fabric or a polyethylene terephthalate nonwoven fabric are laminated. A combination may be used.

The above-mentioned structural body is made of, for example, wood, laminated wood, or the like. The resin sheet is lined with the ceramic outer wall plate by, for example, bonding with an adhesive, fusion by heating, or fusion using ultrasonic waves or high frequency.

The peripheral edge of the ceramic outer panel refers to, for example, a region from the left, right, upper and lower four sides of the ceramic outer panel to about 30 mm inward. When nailing the ceramic outer panel as described below, in order to prevent the ceramic outer panel from being destroyed, for example, the inner edge of the ceramic outer panel is inserted 15 to 30 mm inward from the left, right, upper and lower four sides, for example. Hit the nail into the area of the piece. More preferably, a nail is nailed into a portion 20 mm inward from the four sides of the ceramic outer panel.

Next, an example of the construction method of the exterior wall construction structure of the present invention will be described. First, the above-mentioned structural body is assembled with wood or the like. Next, the waterproof tape is applied to a portion of the structural frame where the rear side surface at the peripheral end of the ceramic outer wall plate abuts. Next, a plurality of the ceramic outer wall boards, which are previously lined with a resin sheet, are pasted on the waterproof tape with their ends abutted to each other. These are fixed to the structural body by nailing to form the load-bearing wall.

Next, the operation and effect of the present invention will be described.
As described above, the outer wall construction structure includes the structural skeleton and a plurality of ceramic outer wall plates. Therefore, the outer wall construction structure has a simple structure and is easy to construct. Also,
Since the number of components is small, the material cost can be reduced. Further, the construction time on site can be reduced.
In addition, since the thickness of the outer wall construction structure excluding the structural frame portion can be reduced, the effective indoor space can be increased.

In addition, since the ceramic outer wall plate has a back surface lined with a resin sheet, it hardly absorbs water and carbon dioxide from the back surface. Therefore, there is no possibility that the above-mentioned ceramic outer wall panel will change its dimensions, and neither carbonation nor neutralization will be promoted. Therefore, it is possible to obtain an outer wall construction structure having excellent durability. In addition, since the above ceramic outer panel is lined with the above resin sheet,
Cracking and chipping can be prevented when nailing the above structural body.

In addition, a waterproof tape is interposed between the rear side surface at the peripheral end of the ceramic outer wall plate and the structural frame. That is, the waterproof tape is interposed between the resin sheet lined on the back side surface of the ceramic outer wall plate and the structural frame. Therefore, it is possible to reliably prevent water from entering from between the ceramic outer wall plate and the structural skeleton. In addition, this eliminates the necessity of separately applying a waterproof sheet required for the conventional exterior wall construction structure, and further simplifies the exterior wall construction structure, and further simplifies the construction.

Further, a cutout groove for ventilation is formed in the body frame of the structural body at a contact surface with the ceramic outer wall plate. Therefore, air permeability can be secured on the indoor side of the ceramic outer wall plate. Accordingly, it is possible to prevent the high-temperature and high-humidity air in the building from being condensed on the back surface of the ceramic outer wall plate and its surroundings.
Therefore, there is no possibility that the above-mentioned structural body is corroded, and an outer wall construction structure having excellent durability can be obtained.

Next, as in the second aspect of the present invention, the ceramic outer wall plate preferably has a thickness of 12 to 25 mm. Thus, the outer wall construction structure has sufficient strength and is easy to construct. When the thickness of the ceramic outer panel is less than 12 mm, it may be necessary to limit the material used for the ceramic outer panel in order to secure sufficient strength. On the other hand, when the thickness is 2
If it exceeds 5 mm, construction may be difficult.

Next, as in the invention according to claim 3, a back side surface at a peripheral end of the ceramic outer wall plate is disposed on the structural frame, and the peripheral end is formed at a predetermined pitch. It is preferable to be nailed and fixed to the structural frame. This makes it possible to obtain an outer wall construction structure with even higher strength. Preferably, the predetermined pitch is 50 to 150 mm. If the predetermined pitch is less than 50 mm, the base material may be damaged around the nailed portion on the front and back surfaces of the ceramic outer panel. On the other hand, if the pitch is 15
If it exceeds 0 mm, it becomes difficult to form a bearing wall.

Next, it is preferable that the waterproof tape has elasticity. As a result, it is possible to securely close and tightly close the small gap generated between the ceramic outer panel and the structural frame, and to reliably prevent inundation.

Next, it is preferable that the waterproof tape is in close contact with the resin sheet of the ceramic outer wall plate and the structural body, respectively. That is, the waterproof tape is in close contact with the resin sheet lined on the back side of the ceramic outer wall plate and the skeleton material constituting the structural body. This makes it possible to more reliably prevent water from entering between the ceramic outer panel and the structural frame.

Next, as in the invention as set forth in claim 6, the adjacent ceramic outer wall plates constituting the load-bearing wall may have a butt portion where their ends are joined to each other, or a mutual end portion may be attached to each other. A jointed part formed by jointing is formed, and a jointless joint consisting of an elastic joint treatment material and a mesh-like body arranged inside the joint is formed on the butted portion and on the surface of the jointed portion. Preferably, it has been applied.

[0030] Thereby, it is possible to reliably prevent water from entering from the butted portion and the decided (gouge) portion,
It is possible to sufficiently secure the strength of the butted portion and the decided portion. In addition, it is possible to obtain an outer wall construction structure in which the joint portion of the ceramic outer wall plate is inconspicuous and has excellent appearance design. In addition, the front side of the above-mentioned consensus portion is the portion where the end on the front side of the ceramic outer wall plate is abutted (FIG. 5).
No. 36)).

Next, it is preferable that the surface of the load-bearing wall be coated with a coating material. As a result, it is possible to obtain an outer wall construction structure having excellent appearance design. Further, it is possible to reliably prevent the ceramic outer wall plate from absorbing water and carbon dioxide, and to surely prevent the dimensional change of the ceramic outer wall plate and the promotion of carbonation and neutralization. Therefore, it is possible to obtain a more durable outer wall construction structure. In addition, the front surface of the load-bearing wall means the front surface of the load-bearing wall including the above-described jointless material when the seamless material is applied.

Next, as in the invention as set forth in claim 8, it is preferable that the through pillars constituting the vertical skeleton of the structural skeleton have the side pillars fixed thereto. Thereby, the through column can be reinforced, and the strength of the structural frame can be secured.

Next, it is preferable that the through pillar and the supporting pillar have the same cross-sectional dimensions. Thereby, the construction cost can be further reduced.

Next, as in the tenth aspect of the present invention,
It is preferable that the end of the trunk is fixed to the front end of the spur pillar. That is, for example, the end of the trunk can be fixed in a state where it is placed on the edge of the upper end of the supporting column. This makes it possible to easily and surely fix the girth to the through column via the attachment column.

Next, as in the eleventh aspect of the present invention,
The notch groove has a depth of 10 to 30 mm and a width of 3 to 150.
mm. This makes it possible to reliably ventilate the ceramic outer wall plate on the indoor side and to ensure the strength of the structural frame.

If the depth of the notched groove is less than 10 mm, it may not be possible to perform sufficient ventilation. On the other hand, when the above-mentioned depth exceeds 30 mm, the strength of the above-mentioned trunk insertion may be reduced and the strength of the structural frame may not be able to be secured. If the width of the notched groove is less than 3 mm, the ventilation may not be sufficiently performed. On the other hand, if the width exceeds 150 mm, nails may not be able to be driven at a pitch required to form a bearing wall.

Next, as in the twelfth aspect of the present invention,
The ridge formed between the adjacent notches is 60 to
Preferably it has a width of 400 mm. This gives
The ventilation inside the ceramic outer wall plate can be reliably performed, and the strength of the structural frame can be ensured. In addition, it is easy to drive nails at a pitch required to form a bearing wall.

If the width of the ridge is less than 60, the contact area between the barrel and the ceramic outer panel is too small,
There is a possibility that the strength of the outer wall construction structure cannot be secured. Further, when the ceramic outer wall plate is fixed to the barrel by nails, nailing may be difficult. On the other hand, if the width of the ridge portion exceeds 400, there is a possibility that ventilation cannot be sufficiently performed.

Next, as in the invention of claim 13,
It is preferable that the ceramic-based outer wall plate is nailed at the protruding portion with respect to the trunk. This makes it possible to easily and surely fix the ceramic outer wall plate to the trunk.
