Description

The present invention relates to an outer peripheral wall construction method of wooden buildings, particularly, the outer peripheral wall construction of wooden buildings to be built in wooden framework construction method capable ensuring the required thickness of insulation material without adding additional heat insulation It relates to the construction method .

  As construction methods of wooden buildings, there are mainly a wooden frame construction method and a wooden frame wall construction method, and most wooden buildings at present are constructed by one of these two construction methods.

  The wooden frame construction method is also called a conventional construction method, and is a structure that supports a building mainly by a frame (wire) such as columns and beams. As for the type and size of the wood used, the base is usually 105 mm x 105 mm, the large pull is 90 mm x 90 mm, the pillar is 105 mm x 105 mm, the intermediary pillar is 30 mm x 105 mm, and the beam is 105 mm x (105 mm, 120 mm, 150 mm , 180mm, 210mm, 240mm, 270mm, 300mm, 330mm, 360mm), bracing 105mm x 45mm, main pine is 105mm x 105mm rice pine, rafters are 45mm x 45mm, etc. There are a great variety, such as Yonematsu. Since stress concentrates on the columns and beams due to the structure, a certain amount of load-bearing walls, such as bracing and structural plywood, can be used to withstand horizontal loads such as seismic loads and wind loads. It is obliged to make a load-bearing floor.

  Since this wooden frame construction method has a high degree of freedom in design, it can flexibly respond to changes in the layout during construction and expansion / reconstruction after construction. There is an advantage that it is easy to secure engineers.

  However, in the wooden frame construction method, bracing is used to obtain earthquake resistance, but there is a problem that the earthquake resistance is inferior compared to a wooden frame wall construction method that obtains earthquake resistance by a wall material (face material). In addition, when the wall is filled with a heat insulating material to obtain heat insulating properties, the thickness of the pillar and the inter-column is normally 105 mm as described above, and the thickness of the heat insulating material should be ensured only within the thickness range. Since the heat insulation power is proportional to the thickness of the heat insulating material, the heat insulation power is weak and may be insufficient. Even if a thicker one is used for the pillars and the studs, if the cost is taken into consideration, the maximum thickness is 120 mm (4 inch square), and if you want to obtain more heat insulation, It is necessary to add additional heat insulation to the outside of the wall or the indoor side, and in that case, it is also essential to underlay the work to support the heat insulating material for additional heat insulation, which complicates the work and increases the construction cost. In addition, there was a problem that condensation in the wall may be caused by a difference in moisture permeability resistance due to a combination of different kinds of heat insulating materials (double heat insulation).

  On the other hand, the wooden frame wall construction method is also called a 2 × 4 construction method (two-by-four construction method), and is a structure that supports a building with walls and floors (face materials) in which structural plywood is struck on the framed wood. . The two-by-four method is based on 2 inch × 4 inch timber, two-by-four (2 inch × 4 inch), two-by six (2 inch × 6 inch), two-by eight (2 inch × 6 inch), two-by ten ( The frame of the house is made up of wood consisting of six types of standards: 2 inches x 10 inches, 2 bar twelve (2 inches x 12 inches), and four-by-four (4 inches x 4 inches), and the bearing walls and rigid floors are solidified there. It is a box-type structure integrated into

  Such wooden frame wall construction methods have standardized timber, so it is possible to reduce labor and cost by mass production at the factory, and most of them are only straight cuts, and complicated processing such as joints and joints is unnecessary. Therefore, there is an advantage that labor cost and construction period can be suppressed without requiring advanced technology. In addition, because the building is firmly integrated with a load-bearing wall and a rigid floor, it is extremely excellent in earthquake resistance and wind pressure resistance, and since it is based on surface elements such as walls and floors, there are very few gaps, Excellent heat insulation, air tightness and soundproofing.

  However, the wooden framed wall construction method has a low degree of freedom in design because the bearing wall occupies an important position in the structure, and is limited in layout, room size, window position, etc. There was a problem that large-scale remodeling that expanded or expanded the department was almost impossible.

  In this way, in each method, advantages and problems are mixed, and as a conventional proposal related to a construction method, for example, instead of a shaft assembly (37 mm ~ A “wooden building” (Patent Document 1) using a two-by-four material of (39 mm) × (88 mm to 90 mm) has been proposed.

  However, the proposal for the above-mentioned “wooden building” is simply a proposal using two-by-four material as a stud, and is not a proposal that can ensure the thickness of the heat insulating material beyond the thickness of the two-by-four material. In order to obtain heat insulation power, it was necessary to add additional heat insulation inside and outside the wall after all.

  Further, a “wooden building” (Patent Document 2) is proposed in which a wall panel produced in a factory such as used in the two-by-four method is fitted and fixed in a wall surface space formed between pillars by a wooden frame construction method.

  However, the proposal of the above “wooden building” is a proposal for simplifying the fixing of the wall panel in the wooden frame construction method, and as above, the thickness of the heat insulating material is more than the thickness of the normal columns and the studs. It was not a proposal that could be ensured, but in order to obtain further insulation, it was necessary to add additional insulation inside and outside the wall after all.

The present applicant pays attention to the design freedom of the wooden frame construction method and the productivity by standardized wood of the wooden frame wall construction method, and the idea of whether high thermal insulation power can be obtained without adding additional insulation. Below, it is possible to secure the necessary insulation thickness without adding additional heat insulation by adopting wood with a predetermined size as a pillar of the outer peripheral wall in a wooden building constructed by the wooden frame construction method. The construction method of an outer peripheral wall is developed, and it leads to the proposal of the "outer wall construction method of a wooden building" concerning this invention.

This invention is made in view of the said problem, and makes it a subject to provide the outer peripheral wall construction method of the wooden building which can ensure the thickness of a required heat insulating material, without adding additional heat insulation.

In order to solve the above problems, the present invention is a method for constructing an outer peripheral wall of a wooden building constructed by a wooden frame construction method, and is a stud arranged between corner columns and structural columns of the outer peripheral wall. As a standard, the two-sided material with a thickness dimension of 8 inches or more is used, the column head of the stud is cut by the width and thickness dimensions of the girders, and the inner surface of the structural pillar and stud with the inner wall material is attached to the outer wall member is mounted on the outer surface of the corner posts and structural columns and stud, insulation is filled in the hollow portion formed by the inner wall material and the outer wall member, the thickness of the studs About the outer peripheral wall which increased thickness by having made the dimension 8 inches or more, it is a construction method in which the wall core is moved outward by a predetermined dimension and offset .

Furthermore, the present invention can employ a construction method in which the studs are planarized from a two-by material to reduce the thickness dimension by a predetermined thickness.

Furthermore, the present invention can employ a construction method in which the corner column is composed of a 3 inch 5 arc (105 mm × 105 mm) or a 4 inch square (120 mm × 120 mm).

According to the outer peripheral wall construction method for a wooden building according to the present invention, it is possible to ensure the necessary thickness of the heat insulating material while maintaining the design freedom in the wooden frame construction method , and add additional insulation. It is possible to obtain an excellent effect that it is possible to obtain a high heat insulation power without performing.

Moreover, according to the outer peripheral wall construction method for a wooden building according to the present invention, the two-by material is mass-produced in a factory or the like by using a two-by material having a thickness of 8 inches or more as a pillar of the outer peripheral wall. Since it is a standard material, it has an excellent effect that it can simplify the work and contribute to reducing the construction cost.

Furthermore, according to the outer peripheral wall construction method for a wooden building according to the present invention, a hollow portion formed of an inner wall material and an outer wall material is used by using a two-by material having a thickness of 8 inches or more as a stud. While a space of more than an inch is secured, the corner column is composed of 3 x 5 arcs (105mm x 105mm) or 4 squares (120mm x 120mm), and the girders (copper material) are 3 x 5 minutes. Since it is configured with a width of (105 mm), it is possible to fill the space between the corner pillars and girders (copper difference material) and the inner wall material, and thereby the corner pillars and girders (copper difference) The material has an excellent effect that it is possible to prevent the heat bridge of the material itself.

Furthermore, according to the outer peripheral wall construction method for a wooden building according to the present invention, the heat insulating material in the hollow portion formed by the inner wall material and the outer wall material for the structural hardware (for example, the battledore bolt) penetrating from the outside of the outer wall material. Therefore, it is possible to prevent a heat bridge caused by the hardware.

It is a principal part enlarged view which shows embodiment of the outer peripheral wall construction method of the wooden building which concerns on this invention.

The present invention is an outer peripheral wall construction method for a wooden building 1 constructed by a wooden frame construction method , and has a thickness dimension as a pillar 24 arranged between a corner pillar 20 and a structural pillar 22 of the outer peripheral wall 10. Using a two-by-material produced in a standard size of 8 inches or more, the head of the stud 24 is cut by the width and thickness dimensions of the girders 44, and an inner wall is formed on the inner surface of the structural pillar 22 or the stud 24. The material 12 is mounted, and the outer wall material 14 is mounted on the outer surface of the corner column 20, the structural column 22, and the intermediate column 24, and the heat insulating material 30 is filled in the hollow portion formed by the inner wall material 12 and the outer wall material 14. The greatest feature is that the outer peripheral wall 10 whose thickness is increased by setting the thickness dimension of the spacer 24 to 8 inches or more is offset by moving the wall core outward by a predetermined dimension .
Hereinafter, an embodiment of an outer peripheral wall construction method for a wooden building 1 according to the present invention will be described based on the drawings.

In addition, the outer peripheral wall construction method of the wooden building 1 according to the present invention is not limited to the embodiments described below, and is within the scope of the technical idea of the present invention, that is, a shape that can exhibit the same operational effects. It can be appropriately changed within a range of dimensions and the like.

FIG.1 and FIG.2 is a top view which shows embodiment of the outer peripheral wall construction method of the wooden building 1 which concerns on this invention, FIG. 1 is a whole top view, FIG. 2 is a principal part enlarged view.
The outer peripheral wall construction method of the wooden building 1 according to the present invention is a construction method of the outer peripheral wall 10 in the wooden building 1 constructed by the wooden frame construction method , and includes the corner pillar 20 and the structural pillar 22 of the outer peripheral wall 10. As the stud 24 arranged between them, a standard-produced two-by-material having a thickness of 8 inches or more is used.

  The two-by material is wood standardized to a predetermined size used in a wooden frame wall construction method. Among them, in the present invention, the thickness is 8 inches or more, that is, two-by-eight (2 inches × 6 inches), A standard size two-by-material made of two-by ten (2 inches × 10 inches) or two bar twelve (2 inches × 12 inches) is used as the stud 24.

  In practice, when using the two-by material as the spacer 24, it is possible to use the standard size as it is. However, the two-by material is planarized to reduce the thickness dimension by a predetermined thickness (approximately 1 to 10 mm). It is preferable to use what is made for the spacer 24. That is, taking a two-by-eight material (2 inches × 8 inches) as an example, a thickness of 8 inches is 184 mm when converted to millimeters, but this is planarized to a thickness of about 180 mm. As a result, moisture permeation of the treated surface is suppressed, which contributes to prevention of corrosion of the wood and prolongs the life, and 180 mm × 105 mm wood generally used in the wooden frame construction method is used as the structural pillar 22. This contributes to simplification of work and cost reduction.

  The inter-column 24 made of the two-by material is provided between the corner column 20 and the structural column 22, specifically, between the corner column 20 and the corner column 20, between the corner column 20 and the structural column 22, or between the structural column 22 and the structural column. 22 is arranged.

  There are no particular limitations on the dimensions of the corner pillars 20 and the structural pillars 22 in the present invention, and it is sufficient to use pillar materials having existing dimensions that are used in a regular manner. However, it is necessary to be the same as the thickness dimension (8 inches, 10 inches, and 12 inches) of the spacer 24 or a small dimension. That is, even if the present invention uses a standard-produced two-by-material having a thickness of 8 inches or more as the spacer 24, the dimensions of the corner column 20 and the structural column 22 are not necessarily matched with the thickness of the spacer 24. There is no need.

  At this time, about the dimension of the said corner pillar 20, the aspect made into 3 dimensions 5 arcmin (105 mm x 105 mm) or 4 dimensions square (120 mm x 120 mm) can be considered. That is, the corner pillar 20 is a pillar material having a substantially square shape in a plan view. However, if this one side dimension is 5 dimensions or more (5 dimensions square or more), the material cost will increase, which is inconvenient. It is an economy. Therefore, the aspect of the corner column 20 used in the regular method, that is, a 3/5 arc or 4 arc is desirable.

  Further, a mode using a beam material for the structural column 22 can be considered. In other words, there is a material having an exactly good size such as 105 mm × 180 mm as a beam material. By attaching a pillar to such a normally used beam and using it as the structural pillar 22, a structure that increases the thickness of the heat insulating material 30 while suppressing the material cost can be realized.

  The inner wall material 12 is attached to the inner side surface of the stud 24. At this time, when the thickness dimension of the structural column 22 is the same as that of the intermediate column 24, the inner wall material 12 is mounted on the inner side surface of the structural column 22 together with the inner side surface of the intermediate column 24. Note that the material and type of the inner wall material 12 are not particularly limited, and may be determined as appropriate, for example, a plaster board. As for the specific structure of the inner wall material 12, as shown in FIG. 2, in view of the airtightness of the wooden building 1, a two-layer structure is used, and a structure in which an airtight sheet 18 made of a polyethylene film or the like is laid between the layers. It can be taken.

  The outer wall material 14 is attached to the outer surfaces of the corner pillars 20, the structural pillars 22, and the intermediate pillars 24. That is, the corner pillars 20, the structural pillars 22, and the interposition pillars 24 are arranged at appropriate positions so that the outer surfaces thereof are in contact with the outer wall material 14 of the outer peripheral wall 10. In addition, about the material and kind of the outer wall material 14, like the inner wall material 12, it does not specifically limit and can determine suitably. As for the specific structure of the outer wall member 14, as shown in FIG. 2, a structure in which the outer wall board 16 is disposed on the outer periphery of a structural plywood 46 made of, for example, MDF or an insulation board via a ventilation layer 15 is adopted. obtain.

  A heat insulating material 30 is appropriately filled in the hollow portion formed by the inner wall material 12 and the outer wall material 14. The material and type of the heat insulating material 30 are not particularly limited, and can be appropriately determined according to the use and cost, such as fiber heat insulating materials such as glass wool and rock wool, and foam heat insulating materials such as urethane foam and styrofoam. .

About the filling aspect of the heat insulating material 30 in a hollow part, the aspect which piles up and fills with the multiple types of heat insulating material 30 other than the aspect filled with a kind of heat insulating material 30 is also possible.
In this regard, in the case of the conventional double heat insulation, it is generally performed that a fiber-based heat insulating material is filled in the outer peripheral wall 10 and a foam-based heat insulating material is attached on the outer side of the load bearing wall. Because of rain and high construction difficulty, the fiber insulation has not been attached to the outside of the bearing wall. However, according to the conventional double heat insulation, not only the cost burden is large, but also the moisture permeability resistance of the foam heat insulating material is higher than that of the fiber heat insulating material. There was a possibility that water vapor entered the inside (inside the hollow portion) of the water and promoted internal condensation.

  In the case of the present invention, since the thickness of the hollow portion is at least 180 mm or more, the same effect as double heat insulation can be obtained by overlapping and filling a plurality of kinds of heat insulating materials 30 in the hollow portion. In this case, it is also easy to fill the outside with fiber insulation and the inside with foam insulation, which was difficult in the past. It will also help prevent internal condensation.

Thus, the outer peripheral wall construction method of the wooden building 1 according to the invention is configured by the corner pillar 20, the structural pillar 22, the intermediary pillar 24, the inner wall material 12 and the outer wall material 14, and the heat insulating material 30. With this structure, a thickness of at least 180 mm or more can be secured between the inner wall material 12 and the outer wall material 14 for the heat insulating material 30, so that a high heat insulating power can be obtained without adding additional heat insulation. .

  By the way, in the present invention, since the thickness of the spacer 24 is 8 inches or more, the outer peripheral wall 10 naturally has a thickness of 8 inches or more (actually, the thickness of the inner wall member 12 and the outer wall member 14 is equal to this). Added thickness), and the thickness is increased from the outer peripheral wall 10 in the conventional method. Therefore, it is necessary to adopt any structure of whether the increased thickness is pushed out to the indoor side or to the outside of the wooden building 1.

  When approaching this protruding structure from another angle, it can be said that “the structure in which the position of the wall core of the outer peripheral wall 10 is moved inward or outward to be offset”. Specifically, moving the wall core inward means that the outer peripheral wall 10 is pushed out indoors, and conversely moving the wall core outward causes the outer peripheral wall 10 to move outside the wooden building 1. It will be looming.

In the outer peripheral wall construction method of the wooden building 1 according to the present invention, a mode in which the wall core moves outward is adopted. In other words, the aspect Oite, by moving the walls wick outward to secure the interior side of the volume when the wooden structure 1 is constructed by Shakuma method. In contrast, In no event building a wooden structure 1 meter module is conceivable manner to move the wall core inwardly, the inner movement of the wall core that immediately outer peripheral wall 10 is pushed out to the indoor side This means that the indoor dimensions are narrowed. Therefore, the present invention adopts a mode in which the outer peripheral wall 10 is aligned inside without changing the indoor dimensions, and thereby the wall core of the outer peripheral wall 10 is moved outward by a predetermined dimension and offset.

In addition, in the outer peripheral wall construction method of the wooden building 1 which concerns on this invention, as shown in FIG. 2, the aspect which arrange | positions the square member 21 for adjustment adjacent to the corner pillar 20 can be considered. The adjusting square member 21 is used to fill a gap around the corner column 20 when the fixed heat insulating material 30 is appropriately cut into the hollow portion of the outer peripheral wall 10 and filled. is there.

  About the width | variety of the foundation raising part 40 of the wooden building 1 in this invention, as shown in FIG. That is, there is no reason to thicken the girders (copper differential material) 44 in proportion to the thickness of the heat insulating material 30, and these are designed to have a width of 3 dimensions and 5 minutes (105 mm) as the base 42. Since the load core of the horizontal member (large beam) in the room is a girder 44 and a copper differential core, the vertical load core P2 is offset at a position shifted from the position of the wall core. At this time, the portions where the structural plywood 46 abut on each column (corner column 20, structural column 22, and intermediate column 24) are cut with clearance, so that the vertical load is applied to the foundation core P <b> 1 in the foundation rising portion 40. Will enter. From the above, since it is sufficient to secure the fabric foundation main reinforcement and the necessary cover thickness in the centering, it is sufficient that the width of the foundation rising portion 40 is about 150 mm. Thus, since it is not necessary to make the width | variety of the foundation standup part 40 into the same dimension as the thickness of the outer peripheral wall 10, it becomes possible to prevent the raise of material cost.

  As for the joining mode of the spar 44 and the structural column 22 or the inter-column 24, the width dimension of the spar 44 and the thickness dimension of the structural column 22 and the inter-column 24 are different. However, as shown in FIG. 4, by making the column heads of the structural column 22 and the interphase column 24 L-shaped by cutting them by the width and thickness dimensions of the beam member 44, the column head and the column head are made flat. It can be constructed without any step in the room, and the construction of the airtight sheet 18 is easy and perfect.

  About the joining aspect of the roof rafter 48, the girder 44, and the structural pillar 22, as shown in FIG. In other words, it is a structure in which the rafters are not cut and the slopes are formed by cutting the girder and stigma according to the slope of the roof rafter 48. At this time, the L-shaped structure is adopted in the same manner as described above for the joining mode of the beam member 44 and the structural column 22. As a result, the continuity of the airtight sheet 18 applied from the roof rafter 48 to the inner wall material 12 is increased, which simplifies the construction work and contributes to the improvement of the housing performance.

The outer peripheral wall construction method of the wooden building 1 according to the present invention composed of the above components is constructed by a wooden frame construction method , and the construction procedure may be in accordance with a regular method, basically → Base → Main part → Shack → Roof → Floor → Wall. Further, structures other than the above-described constituent elements are also constructed according to a regular method in the same manner as the procedure.

The present invention is an outer peripheral wall construction method for a wooden building 1 constructed by a wooden frame construction method , and the two-by-material having a thickness of 8 inches or more is used as the intermediate pillar 24 of the outer peripheral wall 10. Since the materials are standard-produced in large quantities at factories, etc., the labor can be simplified and the construction cost can be reduced, and the thickness of the heat insulating material 30 is required without adding additional heat insulation. It is possible to secure as much as possible, and it is possible to obtain a high heat insulation power, and it is possible to build the design freedom in the wooden frame construction method as it is. I think that the industrial applicability of the “outer wall construction method ” is extremely large.
