Description

  The present invention relates to an outer peripheral wall structure of an externally insulated wooden building by a wooden frame construction method, and a wooden building having the outer peripheral wall structure.

  For insulation construction of wooden buildings such as wooden houses and wooden warehouses, filling insulation that fills the space between vertical members such as pillars and studs and horizontal members such as beams, girders, and trunk gaps with glass wool and other insulation materials In addition, there is external heat insulation in which a plate-like heat insulating material is attached to the outside of the vertical material or the horizontal material, and conventionally, a fire-resistant interior surface material such as a gypsum board has been attached to the indoor side of the column. Therefore, the outer heat insulation has a problem that the outer wall becomes thicker by the thickness of the heat insulating material than the filling heat insulation, and the substantial floor area becomes narrow. However, the outer periphery of the building can be covered with a heat insulating material without gaps, and there is an advantage that uniform and high heat insulation can be obtained, and condensation in the wall does not occur. It is coming.

  In Patent Document 1, a heat insulating panel provided with an interior surface material and a heat insulating material is arranged outside the pillar, and further, a pillar as a structural member that is usually arranged between the pillars is arranged outside the heat insulating panel. An outer peripheral wall structure is disclosed in which the floor area is expanded by opening the space between the pillars to the indoor side after removing the pillars between the pillars and attaching them to the set. In the previous heat insulation work, electrical / communication wiring, water pipes, and gas equipment piping were installed in the space between the columns covered with the interior surface material. Therefore, before installing the interior surface material on the indoor side of the column,・ It was necessary to determine the position of the communication equipment, the water circumference, and the gas equipment. However, in the structure of Patent Document 1, the interior surface material is attached to the outdoor side of the pillar. It can be installed by selecting the location of the water circumference and gas equipment.

Moreover, you may have the open area | region which is not provided with this specific structure other than the open area | region provided with the specific structure which concerns on this invention.

  The shaft assembly according to the present invention includes columns and cross members. In the present invention, “columns” refer to through columns and tube columns, which are structural members. In recent wooden buildings, there is a structure that does not use a pillar, and the present invention includes such a structure. In the case of a structure that does not use a through pillar, a pipe pillar is disposed at the position of the through pillar. Further, in the present invention, the “cross member” is a structural member arranged in the horizontal direction such as a beam, a girder, a trunk difference, and a base.

  Further, in the present invention, the electric / communication wiring drawn out in the gap between the interior surface material and the heat insulating material is an electric / communication wire attached to a shaft, wall surface, ceiling, floor, etc., such as pillars and beams exposed indoors. Wirings and cables connected to communication facilities, such as electrical / communication facilities, such as lighting equipment, audio / video equipment, air-conditioning equipment, operation panels and switches, grounding terminals, etc. Power outlets, intercom indoor equipment, landline telephones and LAN outlets.

  Hereinafter, with reference to the drawings, a two-story wooden house will be described as an example as a preferred embodiment. The dimensions, materials, shapes, and relative arrangements of the constituent members described in these embodiments do not limit the scope of the present invention. In addition, the well-known or well-known technique of the said technical field is applied regarding the part which is not illustrated or described in particular in this specification.

  FIG. 1 is a schematic cross-sectional view showing a preferred embodiment of the outer peripheral wall structure of the present invention, which is a schematic cross-sectional view parallel to the vertical direction and the thickness direction. 2A is a schematic cross-sectional view taken along the line AA ′ in FIG. 1, FIG. 2B is a schematic cross-sectional view taken along the line BB ′ in FIG. 1, and FIG. It corresponds to a CC ′ cross-sectional schematic diagram. 3 is a perspective view schematically showing the configuration of the hollow panel used for the construction of the outer peripheral wall structure of FIG. 1, FIG. 4 is an enlarged view of the vicinity of the trunk difference of FIG. 1, and FIG. 5 is the implementation of FIG. It is a perspective view which shows the state which partially cut off the 1st floor part of the form. In the drawings, the same reference numerals are assigned to the same members, but in FIGS. 2 and 5, the reference numeral 10 indicating the hollow panel is omitted for convenience.

  Since the outer peripheral wall structure of the present invention is externally insulated, as shown in FIG. 1, a heat insulating material 15 is disposed on the outer side (right side of the drawing) of the shaft set such as the column 11, the base 12, and the trunk difference 13. However, in the present invention, the interior surface material 14 is first disposed outside the shaft assembly, and the spacer 16 is disposed outside the interior surface material 14, and the spacer 16 is attached to the shaft assembly. And the heat insulating material 15 is arrange | positioned through this predetermined | prescribed clearance gap with this interior surface material 14 in the outer side of the interior surface material 14. FIG. This example shows an example in which the heat insulating material 15 is arranged outside the stud 16. In this example, in consideration of the ease of construction work, the hollow panel 10 shown in FIG. 3 (a), in which the plate-like heat insulating material 15, the interior surface material 14, and the spacer 16 are integrated, is assembled. The form attached to is shown. Further, this example is a configuration example in which an open region having a specific structure according to the present invention is provided at one corner portion of the outer peripheral wall.

  In the hollow panel 10 of this example, the positions of the studs 16 are at least both ends of the hollow panel 10 in the horizontal direction as shown in FIGS. 2 and 3A in consideration of the ease of mounting the studs 16 to the shaft assembly. To place. Further, it is preferable to reinforce the panel 10 by disposing a further intermediate column 16 between the intermediate columns 16 and 16 at both ends. In the hollow panel 10 of this example, since the interior surface material 14 and the heat insulating material 15 are integrated via the spacers 16, the gap corresponding to the depth of the spacers 16 (the length in the thickness direction of the outer peripheral wall) is hollow. Formed in panel 10.

  The stud 16 used for the hollow panel 10 corresponds to a stud as a structural member that has been conventionally arranged between the pillars 11 and 11, and also functions as a structural member after being attached to the shaft assembly in the present invention. Therefore, it is preferable that the depth of the studs 16 is 60 mm to 120 mm, the width is 45 to 90 mm, and the pitch is 450 mm to 910 mm. Further, the depth of the gap between the interior surface material 14 and the heat insulating material 15 (t in FIG. 3A) is preferably 60 mm or more so that the electrical / communication wiring can be routed, and the upper limit is determined by the depth of the stud 16. Therefore, 120 mm or less is preferable.

  Further, as the interior face material 14, a material that satisfies the fire resistance standard of the area where the wooden building of the present invention is built, has strength as a wall surface, and has a cosmetic property that is not affected even when exposed to the indoor side is selected. The Therefore, in areas where fire-resistant wall materials are not required on the indoor side, interior materials such as wallpaper (cloth) may be attached to plywood. In areas where fire-resistance standards are strict, wall materials with fire resistance and cosmetics In addition, a combination of fire-resistant wall materials and interior materials such as wallpaper is used. Specifically, for example, 9.5 mm-thick “MOIS (registered trademark)” (Mitsubishi Corporation Building Materials Co., Ltd.) having fire resistance and cosmetics is preferably used. The inter-column 16 and the interior surface material 14 may be integrated with an adhesive so that the indoor surface of the interior surface material 14 is not affected, but the adhesive strength between the interior surface material 14 and the inter-column 16 is weak. Alternatively, a structure in which a plywood is attached to the inter-column 16 with a nail or the like and the interior surface material 14 is bonded to the plywood may be employed.

  Moreover, as the heat insulating material 15, the plate-shaped heat insulating material used for the heat insulation construction of a general wooden house is used preferably. Specifically, for example, “Neofoam (registered trademark)” (Asahi Kasei Construction Materials Co., Ltd.) of Class A phenol foam heat insulation board No.1 type 2 F ☆☆☆☆ S prescribed in JIS A 9511 foamed plastic heat insulation material, Fenova board (registered trademark) "(Sekisui Chemical Co., Ltd.) is preferably used. The thickness of the heat insulating material 15 is appropriately selected depending on the environment of the area where the wooden building is constructed.

  Although the integration means of the spacer 16 and the heat insulating material 15 is not specifically limited, it is preferable to integrate using the adhesive like the interior surface material 14, and a nail, a screw, etc. may be used as needed.

  In the present invention, the stud 16 is attached to the shaft set and functions as a structural member. Therefore, the hollow panel 10 is fixed to the shaft assembly by attaching the studs 16 to the shaft assembly. In FIG. 1, the stud 16 is attached to a cross member such as a trunk difference 13 and a base 12 in the vertical direction. Therefore, the upper end of the hollow panel 10 that constitutes the outer wall of the first floor is up to the center in the vertical direction of the trunk difference 13 on the first floor, and the upper half of the trunk difference 13 constitutes the outer wall of the second floor. The lower end of the hollow panel 10 is attached. It is preferable to attach the intermediate column 16 at a position overlapping the column 11 also to the column 11. As shown in FIG. 4, the spacers 16 are attached to the shaft assembly from the outside using attachment members such as screws 31, screws, and nails. In addition, when attaching the hollow panel 10 to a shaft assembly, you may temporarily fix the hollow panel 10 to a shaft assembly using a double-sided tape, an adhesive agent, etc. previously. Further, it is preferable that the airtight tape is attached to the boundary between the hollow panels 10 adjacent to each other in the horizontal direction and the vertical direction to improve the airtightness. Further, a waterproof sheet or the like may be appropriately attached to the outside of the hollow panel 10.

  In addition, in the corner part of the outer peripheral wall structure of the present invention, as shown in FIG. 2, square members 23 having dimensions corresponding to the inter-columns 16 and the interior surface material 14 are attached to the outside of the columns 11 so as not to cause heat-insulating defects. The heat insulating material 15 may be disposed outside the square member 23.

  In the outer peripheral wall structure of the present invention, the exterior member 18 is attached to the outermost part through the ventilator edge 17. As shown in FIG. 4, the ventilating drum edge 17 is attached to the stud 16 using a mounting member such as a screw 32. Therefore, if a mark indicating the position of the stud 16 is provided on the outside of the heat insulating material 15 in advance, the ventilating drum Positioning of the edge 17 is easy and preferable. As the ventilation trunk edge 17, a vertical trunk edge conventionally used as a base material of the exterior material 18 is preferably used, and the thickness (length in the thickness direction of the outer peripheral wall) is 18 mm to 20 mm, and the width (outer peripheral wall). The length in the horizontal direction parallel to the wall surface is about 30 mm to 60 mm.

  The exterior material 18 is preferably a commercially available exterior panel such as metal or ceramic siding or ALC (lightweight cellular concrete board) that satisfies the fire resistance standards of the outer wall, but is not limited to these in the present invention. It is not something. The exterior member 18 is attached to the trunk edge 17 using an attachment member such as a screw 33.

  In the outer peripheral wall structure of the present invention, since the interior surface material 14 is provided on the indoor side, it is not necessary to attach an interior surface material such as a gypsum board further inside. Further, since the studs 16 are attached to the shaft assembly from the outside, the region has a resistance against wind pressure from the outside. Therefore, in such an area, it is not necessary to attach a stud between the pillars 11 and 11, and a wide floor area can be obtained as an open area where the pillars 11 and 11 are opened indoors. Moreover, since all the members including the interior surface material 14 are attached from the outside of the shaft assembly, the attachment members are not exposed to the indoor side, and the appearance is good.

  In the outer peripheral wall structure of the present invention, since there is a gap between the interior surface material 14 and the heat insulating material 15, the electric / communication wiring is exposed to the indoor side by drawing the electric / communication wiring into the gap. Can be minimized. Further, when drawing out the electrical / communication wiring into the gap, it is only necessary to make a hole in the interior surface material 14, so that workability is good.

  1 and 4 show a configuration in which the floor structure of the second floor composed of the floor base material 25 and the floor finishing material 26 is the ceiling of the first floor, but 1 below the floor structure of the second floor. When the ceiling member of the floor is provided and used as the ceiling, by attaching the ceiling member below the trunk difference 13, the gap formed between the ceiling member of the first floor and the trunk difference 13 is used, The electrical / communication wiring drawn out to the ceiling of the first floor can be drawn out directly into the gap between the interior surface material 14 and the heat insulating material 15. Therefore, the wiring from the ceiling of the first floor or the electrical equipment attached at a position away from the outer peripheral wall to the operation panel or switch attached to the outer peripheral wall is connected between the ceiling back, the interior surface material 14 and the heat insulating material 15. Can be routed to the gap between them. Similarly, by attaching a ceiling member on the second floor under the roof to form a ceiling on the second floor, exposure of electrical / communication wiring to the indoor side of the second floor can be suppressed. In addition, the electrical / communication wiring drawn out in the gap between the interior surface material 14 and the heat insulating material 15 on the second floor can be routed to the first floor using the gap.

  Further, in this example, as shown in FIG. 1, the joist is not disposed on the base 12, and a structural plywood having a thickness of 24 mm or more is directly disposed on the base 12 as the floor base material 25, Since the floor finishing material 26 is disposed, there is no gap between the base 12 and the floor base material 25. Normally, the electrical / electrical power drawn into the gap between the interior surface material 14 and the heat insulating material 15 is provided. There is no area for drawing communication wiring under the floor.

  Therefore, in the present invention, by providing the recess 12a on the upper surface of the base 12, the electrical / communication wiring drawn out in the gap between the interior surface material 14 and the heat insulating material 15 can be easily drawn out under the floor. . Specifically, as shown in FIG. 5, a recess 12 a that penetrates inward and outward, that is, penetrates in the thickness direction of the foundation 22 is formed on the upper surface of the base 12 disposed on the foundation 22. The hollow panel 10 is arranged on the foundation 22 so that the interior surface material 14 is adjacent to the base 12. Thereby, a hole is made in the interior surface material 14 from under the floor of the wooden building through the recess 12a, and the wiring drawn out in the gap between the interior surface material 14 and the heat insulating material 15 can be easily pulled out under the floor. .

  Moreover, in this invention, as shown in FIG.3 (b), by providing the opening part 14a previously in the area | region which overlaps the outer side opening part of the recessed part 12a of the interior surface material 14, the interior surface material 14 or It is not necessary to make a hole in the interior surface material 14 in order to draw out the electric / communication wiring after the hollow panel 10 is attached to the shaft assembly.

  In addition, when the joist is arranged between the floor base material 25 and the base 12, with respect to the base 12 arranged in the direction intersecting with the joist, a gap corresponding to the height of the joist between the adjacent joists is provided between the base 12 and the under floor. Since it opens between the base material 25, it is possible to make a hole in the interior surface material 14 using such a gap, but on the foundation 12 arranged in parallel with the joist, the joist is arranged and the floor foundation Since the material 25 is arranged, there is no gap from the floor to the interior surface material 14. Therefore, even in the case where joists are used, in a region where the joists and the base 12 are parallel, the recesses 12a are provided in the base 12 so that the electric / communication wiring can be easily drawn under the floor.

  It is desirable that the recess 12a has a size within a range that maintains the strength of the base 12 while securing a length necessary for taking out the electrical / communication wiring. Therefore, the depth of the recess 12a is preferably 30 mm or more and 1/2 or less of the height of the base 12. The opening width of the recess 12a (the length in the direction parallel to the wall surface of the foundation 22) is preferably 30 mm or more and 470 mm or less, and the distance between the adjacent recesses 12a and 12a is preferably 120 mm or more. In addition, since the electric / communication wiring cannot be taken out in the region overlapping the column 11 and the inter-column 16, the recess 12 a is provided avoiding the region overlapping the column 11 and the inter-column 16.

  In this example, as shown in FIGS. 1 and 5, the hollow panel 10 is disposed on the foundation 22 via the receiving material 28, and the drainage metal 27 is attached to the receiving material 28. These are members used as necessary.

  Moreover, in this example, the heat insulating material 15 is arrange | positioned on the base 12, and the upper part from the foundation 22 is covered with the heat insulating material 15 altogether. Therefore, as shown in FIG. 1 and FIG. 5, by applying a heat insulation work by attaching a heat insulating material 29 to the outside of the foundation 22, a heat insulation work without heat insulation defects is performed between the foundation 22 and the upper part thereof. Can do. In addition, the foundation thermal insulation construction uses a sealed foundation with a flat upper surface and no vent holes communicating from the bottom to the outside, and by attaching a heat insulating material to the outside of the foundation, the outer insulation of the entire foundation Say to give. Therefore, also in this invention, when performing the said foundation heat insulation construction, as the foundation 22, the upper surface is flat, and the airtight foundation in which the ventilation hole connected to the exterior from under the floor is not provided is used.

  As described above, in the present invention, since the electrical / communication wiring can be easily drawn under the floor by making a hole only in the interior surface material 14, the electrical / communication wiring is constructed after the construction of the outer peripheral wall of the present invention. The electric / communication equipment can be attached to a desired position without exposing the wall to the indoor side wall surface. Therefore, after the delivery of the wooden building of the present invention, the owner can freely select the position of the electrical / communication equipment, and the electrical / communication equipment can be installed while suppressing the exposure of the electrical / communication wiring to the indoor side. In addition, it is possible to easily change the position of the electrical / communication equipment once attached when redesigning or remodeling the room. Moreover, since the operation | work which draws out electrical / communication wiring to the clearance gap between the interior surface material 14 and the heat insulating material 15 and the operation | work pulled out under a floor | bed is easy, the period which concerns on the said operation | work is short, and can be implemented cheaply.

  As described above, in the present invention, the gap between the interior surface material 14 and the heat insulating material 15 is used for routing the electric / communication wiring. However, a water pipe and a gas pipe may be arranged in the gap. . In the present invention, since such a gap is formed by the studs 16, a sufficient size is ensured for the arrangement of these pipes. When using a conventional hard pipe, it is necessary to arrange the pipe in the gap between the interior face material 14 and the heat insulating material 15 when constructing the outer peripheral wall. Recently, flexibility has been widely used. In the case of using the pipe having the pipe, the pipe can be arranged in the gap between the interior surface material 14 and the heat insulating material 15 after the construction of the outer peripheral wall, similarly to the electric / communication wiring. Therefore, not only electrical / communication equipment but also water and gas equipment can be installed by selecting the position freely after construction of the outer peripheral wall and suppressing the exposure of the pipe to the wall surface.

  The wooden building of the present invention is characterized by having the above-described outer peripheral wall structure of the present invention. However, a part of the outer peripheral wall may be a bearing wall. FIG. 6 is an example thereof, and is a schematic cross-sectional view of a position corresponding to the B-B ′ cross section of FIG. 1. As shown in FIG. 6, a structural plywood 52 is attached parallel to the outer peripheral wall to cover the corner pillar 11 and the pillar 11 adjacent thereto in the embodiment shown in FIGS. Further, the structural plywood 52 is attached so as to be orthogonal to the outer peripheral wall so as to connect the pillar 11 on the outer peripheral wall side and the pillar 11 newly provided indoors to constitute a bearing wall ( This is an example in which two places of the outer peripheral wall are load bearing walls. In FIG. 6, the intermediate pillar 51 for supporting the structural plywood 52 is arranged in the bearing wall. However, when the structural plywood 52 is as thick as about 24 mm, the intermediate pillar 51 can be omitted. In this embodiment, the bearing wall is a face bearing wall in which the structural plywood 52 is attached to the columns 11 and 11. .

  Moreover, in the said embodiment, although the example which constructs an outer peripheral wall using the hollow panel 10 which integrated the interior surface material 14 and the heat insulating material 15 via the spacer 16 was given, in this invention, it is a shaft assembly. If the interior surface material 14 and the heat insulating material 15 are provided with a gap between them and the space 16 is attached to the shaft assembly, the present invention is not limited to the above embodiment. .

  For example, in this invention, you may arrange | position a plywood between the spacer 16 and the heat insulating material 15, and in that case, as shown in Fig.7 (a), the interior surface material 14, the spacer 16, and the plywood. The hollow panel 10 which united 41 and the heat insulating material 15 is comprised, and this hollow panel 10 can be attached to a shaft set similarly to previous embodiment. In this hollow panel 10, since the heat insulating material 15 is bonded to the plywood 41 with an adhesive after being attached to the plywood 41 and the intermediate column 16 with an adhesive or a nail or a screw, the integrated strength of the heat insulating material 15 and the intermediate column 16 is obtained. Becomes higher. Moreover, as shown in FIG. 7B, after forming the hollow panel 10 in which the interior surface material 14, the interposition column 16, and the plywood 41 are integrated, and attaching the hollow panel 10 to the shaft assembly, the heat insulating material 15 is formed. May be attached to the plywood 41.

  Further, in the present invention, a plywood may be disposed outside the heat insulating material 15 to reinforce, and in that case, a plywood 41 is attached to the outside of the heat insulating material 15 as shown in FIG. Further, by using the hollow panel 10, it can be easily attached to the shaft assembly. In such a configuration, a further plywood may be further disposed between the spacer 16 and the heat insulating material 15.

Further, as a reference example, in FIG. 8B , the plywood 41 and the interior surface material 14 are integrated via the intermediate pillar 16, and a predetermined gap is formed between the intermediate pillars 16 and 16 and the interior surface material 14. The hollow panel 10 filled with the heat insulating material 15 is shown . In this case, the depth of the gap between the interior surface material 14 and the heat insulating material 15 is small with respect to the depth of the studs 16, and the outer peripheral wall structure of the present invention can be implemented with the minimum depth. However , as compared with the configuration in which the spacer 16 is disposed between the interior surface material 14 and the heat insulating material 15, the configuration in which the heat insulating material 15 is disposed between the spacers 16 and 16 has a gap between the heat insulating material 15 and the spacer 16. In view of heat insulation, the former is more advantageous.

  In any of the configurations, the hollow panel 10 is not configured, and after attaching the interior panel 14 to the shaft assembly, the plywood 41 is disposed between the studs 16 and, if necessary, between the studs 16 and the heat insulating material 15. Moreover, you may attach the heat insulating material 15 and the plywood 41 arrange | positioned outside the heat insulating material 15 as needed.

  In the above description, a two-story house has been described as an example as an embodiment. However, the wooden building of the present invention is not limited to this, and it may be a one-story or three-story building. It is preferably applied to tenement houses such as three houses and apartments, meeting places, stores, warehouses, and various facilities.
