Description

  The present invention relates to an outer wall structure of a building which has been subjected to a ventilation construction method using an air receiving material effective in preventing the occurrence of condensation inside the outer wall of the building.

  Conventionally, in the outer wall structure of a building, a waterproof / breathable sheet is pasted on the base structure material such as pillars, studs, trunk differences, trunk edges, foundations, etc., and a base panel is pasted on it, and the outer wall is directly on it. Construction methods have been carried out by attaching panels. However, in recent years, with the progress of high airtightness and high thermal insulation in buildings, there has been a problem that air circulation is hindered and condensation occurs inside the outer wall structure. Therefore, in the past, ventilation receivers made of timber were used in the ventilation structure of the outer wall, but the inhomogeneity and strength of the wood strength due to defects and defects such as knots, dead knots, rot, etc. of the wood material In many cases, the dimensional stability due to the decrease and the moisture content variation due to moisture is lacking, resulting in a decrease in the wall magnification of the wall. Therefore, there is an outer wall structure using a ventilation receiving material using a structural plywood having excellent dimensional stability and few defects. (For example, refer to Patent Document 1).

  In addition, if air vents are provided in the horizontal direction in the air receiving material and the outer wall panel is vertically stretched, the air flow receiving material can be attached in the horizontal direction without inhibiting air flow in the vertical direction. In order to realize a good outer wall structure, a ventilation edge is attached horizontally or vertically to the surface of the foundation structure of the building at predetermined intervals, and a recess is formed on the inner surface of the edge. There is a ventilation trunk edge in which a communication concave part communicating with the concave part is formed on both side surfaces of the trunk edge material. (For example, refer to Patent Document 2).

  However, the ventilation receiving material described in the above-mentioned Japanese Patent Application Laid-Open No. 2002-194829 does not have a ventilation hole for promoting air circulation in the ventilation receiving material itself, and the housing is particularly inferior in the living environment, particularly in the humidity environment. In the outer wall, there is a certain limit to the promotion of air circulation inside the outer wall. In addition, the ventilation trunk edge described in JP-A-5-5330 has a communication recess formed only in a direction substantially orthogonal to the lateral direction of the ventilation trunk edge, that is, the major axis direction. No communication recess is formed in the direction. Therefore, unless the size of the communication recess is set to a certain level or more, the amount of air flow is limited and the effect of preventing condensation cannot be exhibited. Further, if the size of the communication recess is too large, the strength of the ventilating cylinder edge itself is weakened, and there is a risk of breakage during or after construction. In particular, since the recesses are formed from the front and back surfaces of the ventilator rim, when a load due to external force is applied, stress concentration occurs in the recesses, which may cause damage.

  In addition, in the outer wall structure, if there is unevenness or a step in the underlying structure material, if the outer wall panel is attached by attaching a trunk edge for ventilation, that is, a ventilation receiving material, to the adjacent outer wall panel Steps and unevenness are likely to occur between the surfaces, which causes cracks such as mortar finish on the surface.

  Further, at the position where the other end in the longitudinal direction of the outer wall panel 2 comes, the wide vertical ventilation receiving material 3a is attached at a position where it is retracted by a dimension corresponding to the projecting dimension, and a recess U is formed. In this case, the vertical ventilation receiving material 3a is not necessarily wide. At the position where the concave portion U comes, an end ventilation member E is attached on the column 5 via a waterproof / breathable sheet 7 in advance by site construction. The end ventilation receiver E may be the same as the wide vertical ventilation receiver.

It may be narrow. As an example, at the position where the upper end portion of the outer wall panel 2 comes, a convex portion T is formed by projecting approximately half the width dimension of the lateral ventilation receiving material 3b, while on the other hand, at the position where the lower end portion comes, A concave portion U is formed at a position retracted by a size corresponding to the size of the convex portion T. Further, a ventilation path 4 is secured in the vicinity of the vertical ventilation receiving material 3a and the horizontal ventilation receiving material 3b.

  In FIG. 5, the detail of the ventilation receiving material of 2nd embodiment of this invention is shown. A perspective view thereof is shown in (a), a cross-sectional view taken along the line C-C is shown in (b), and a cross-sectional view in a state where adjacent vertical or horizontal ventilation receiving members are fitted to each other is shown in (c).

  The ventilation receiving member 3 is a member having a substantially rectangular cross-sectional shape and an elongated appearance. A fitting convex portion KT is formed on one side surface in the longitudinal direction, and a fitting concave portion KU is formed on the other side surface in the longitudinal direction. Is formed. Furthermore, a partition piece S is provided in the vicinity of the center in the width direction along the longitudinal direction for improving the strength. The position of the partition piece S may not be the center in the width direction as shown in this example. What is necessary is just to set a position suitably. Further, although depending on the material of the ventilation receiving material 3, the partition piece S can be omitted when the material is strong in strength.

  In addition, a hollow portion is formed in the longitudinal direction in the ventilation receiving material 3, and a ventilation hole TH in the longitudinal direction is provided. Further, a short-side vent hole YH is provided at the position of the fitting convex part KT and the fitting concave part KU on the left and right side surfaces of the ventilation receiving material 3. As shown in this example, the short-side vent hole YH is not necessarily formed directly above the fitting convex part KT and the fitting concave part KU. The fitting convex part KT and the fitting concave part are not necessarily formed. The position may be slightly deviated from directly above the position of KU. What is necessary is just to be formed so that air may distribute | circulate in the transversal direction of the ventilation receiving material 3. FIG.

  Further, in the present example, the ventilation receiving material 3 of the present invention has a cross-sectional shape taken along the line CC, and is substantially rectangular except for the fitting convex part KT. May have a flat surface substantially parallel, and may be a cross-sectional view, a square, a substantially parallelogram, a substantially hexagon, and other polygons. Further, the left and right side surfaces may not be parallel surfaces as in this example, but may be curved surfaces. The fitting convex part KT and the fitting recessed part KU should just be formed in both sides | surfaces, and they should mutually fit.

  Further, the opening shape of the vent hole TH in the longitudinal direction may be a circle, an ellipse, or other irregular shapes other than a square. Further, the short side vent hole YH on the side surface may be a plurality of small holes provided on the fitting convex part KT and the fitting concave part KU along the longitudinal direction of the side surface as shown in this example. Also, it may be a long oval or rectangle formed along the longitudinal direction. Further, the intervals between the small holes are not necessarily equal. An appropriate interval may be provided. The shape of the small hole formed as the short-side vent hole YH on the side surface of the vent receiving material 3 may be a rectangle, a triangle, an ellipse, or other irregular shapes other than the circle as shown in this example.

  The longitudinal vent TH and the short vent YH pass through the vent receiving material 3, respectively. In addition, it is preferable for air circulation that the longitudinal ventilation hole TH and the transverse ventilation hole YH cross each other and communicate with each other inside the ventilation receiving material 3. By communicating in this way, the flow of air is in communication with each other inside the wall body, and the effect of preventing condensation is further increased.

  Moreover, (c) of FIG. 5 is sectional drawing of the state which fitted the ventilation receiving material 3 adjacent to each other. As can be seen from FIG. 5C, the protruding length of the tip of the fitting convex part KT is designed to be shorter than the depth of the fitting concave part KU. That is, the front end portion of the fitting convex portion KT is configured not to reach the partition piece S. Therefore, even if the positional relationship in the longitudinal direction between the two adjacent air receiving members 3 is slightly shifted, the air flow from the vent hole YH in the short direction is not hindered.

  Moreover, the material of the ventilation receiving material 3 of the second embodiment of the present invention may be substantially the same as that of the first embodiment. The dimensions and thickness of the air receiving member 3 may be substantially the same as those of the first embodiment. As in the first embodiment, there are two types of width dimensions, ie, a wide member and a narrow member, and only one narrow member having a width of about 45 mm may be used. When used on a wide structural material such as the pillar 5, the trunk difference 8, the base 10, etc., the two air-receiving members are fitted to make the width wide. Moreover, what is necessary is just to set suitably the magnitude | size which can fit each other as the magnitude | size of the fitting convex part KT and the fitting recessed part KU.

  In FIG. 2C, a cross-sectional view of the outer wall structure constructed using the ventilation receiving material 3 of the second embodiment of the present invention is shown. Between the pillars 5 and 5, the pillars 6 are attached at intervals of about 1.5 inches (about 450 mm), and a heat insulating material D is attached therebetween. The heat insulating material D is attached by mechanical means such as staples in combination with an adhesive. A waterproof / breathable sheet 7 is attached thereon, and a vertical ventilation receiving member 3a is attached to a position where the pillars 5 and the inter-columns 6 come. Further, the horizontal ventilation receiving material 3b is attached to the position where the horizontal members such as the trunk difference 8, the trunk edge 9, and the base 10 come.

  Even if unevenness or level difference occurs on the surface of the wooden frame foundation structure material such as the pillar 5, the inter-column 6, the trunk difference 8, the trunk edge 9, and the base 10, the vertical ventilation receiver 3a and the horizontal By fitting the fitting convex part KT and the fitting concave part KU provided in the ventilation receiving material 3b to each other, the unevenness and the level difference are absorbed, and a level difference is formed between the outer wall panels 2 to be applied on the surface. Etc. can be effectively prevented. Therefore, even if a mortar finish is applied thereon, there is no risk of surface cracks such as cracks after construction.

  The ventilation receiving material 3 according to the second embodiment of the present invention is installed and constructed on the structure base material such as the pillar 5, the intermediary pillar 6, the trunk difference 8, the trunk edge 9, and the base 10, and the outer wall panel 2 thereon. The vertical ventilation receiving material 3a and the horizontal ventilation receiving material 3b are attached in advance at predetermined positions on the back surface of the outer wall panel 2 at a factory or the like (see FIG. 6). There are two possible construction methods that do not require attachment. In any case, the fitting projections KT and the fitting depressions KU provided in the vertical ventilation receiving material 3a and the horizontal ventilation receiving material 3b are fitted to each other, so that the surface between adjacent outer wall panels can be accurately detected. There is no level difference, and the outer wall panels 2 can be connected and constructed firmly.

  In particular, in the case of the air receiving material of the first embodiment, not only the air receiving material on the back surface of the outer wall panel, but also a waterproof / moisture permeable sheet, a pillar, a heat insulating material, etc. are attached in advance at a factory, etc. It is also possible to significantly improve the performance.

  In FIG. 6, the example at the time of attaching the ventilation receiving material 3 of 2nd embodiment of this invention to the back surface of the outer wall panel 2 beforehand in the factory etc. is shown. (A) is a plan view, and (B) is a cross-sectional view along the line DD. The outer wall panel 2 is attached so that one end face in the longitudinal direction of the back surface of the outer wall panel 2 faces the fitting recess KU outward and the outer wall panel end face is aligned with the end face of the vertical ventilation receiving member 3a. Attach with nail, staple or adhesive. The other end is attached so that the fitting projection KT of the longitudinal ventilation receiving member 3a faces outward and only the fitting projection KT protrudes from the end face of the outer wall panel. The vertical ventilation receiving material 3a is also attached to the position of the stud at the substantially central portion in the width direction of the outer wall panel. These three longitudinal ventilation members 3a are not necessarily as wide as the column width. All three may be wider than the stud width or slightly wider.

  In addition, at the upper and lower ends of the rear surface of the outer wall panel, two horizontal ventilation receiving materials 3b are attached to the upper and lower ends, respectively. The attachment state and attachment method are the same as those of the longitudinal ventilation receiving material 3a. The width dimension of the horizontal ventilation receiving material may be the same as that of the vertical ventilation receiving material. Further, a ventilation path 4 is secured in the vicinity of the vertical ventilation receiver 3a and the horizontal ventilation receiver 3b. In this way, the construction is such that the fitting convex part KT and the fitting concave part KU are fitted to each other between adjacent outer wall panels when viewed in cross section after construction.

  If the ventilation receiving material 3 of the present invention is used, the circulation of the air inside the wall body is promoted. Therefore, the environmental conditions are so bad against moisture that the circulation of the air inside the wall body cannot be handled by the conventional ventilation path alone. Even in the lower house, it is possible to effectively prevent condensation.
