Japanese Patent Laying-Open No. 2005-320853

  Here, when the opening frame is disposed at a position separated from the column, the side surface of the vertical frame portion is separated from the side surface of the column, and the vertical frame portion cannot be directly fixed to the column. Therefore, it is conceivable to provide a stud between the opening frame and the column, and fix the vertical frame portion of the opening frame to the column via the stud. However, when the separation distance between the column and the opening frame is larger than the width dimension of the stud, the stud is separated from at least one of the column and the opening frame, so that the stud is directly fixed to both the column and the opening frame. It is necessary to use a stud having the same width as the distance between the column and the opening frame. In this case, a method of preparing a plurality of types of studs and using the studs properly according to the separation distance between the column and the opening frame is conceivable. However, this method increases the cost burden and the work burden.

  This invention is made | formed in view of the said situation, and even if an opening frame is spaced apart and provided from the pillar, it is providing the wall structure which can fix the opening frame to a pillar suitably. It is the purpose.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

  In the wall structure of the building of the first invention, a wall opening having a pair of wall materials and a plurality of studs provided between the wall materials is provided with a wall opening, and between the pair of wall materials. A wall structure of a building in which a pillar is provided in addition to the plurality of studs, wherein the wall opening is provided with an opening frame having a vertical frame portion and a horizontal frame portion, and the plurality of studs Includes a gap stud provided in a gap between the column and the vertical frame portion, extending along the vertical frame portion and having the vertical frame portion fixed thereto, and the gap stud is a connecting member. The connecting member has a stud side fixing portion fixed to the gap stud and a column side fixing portion fixed to the column. .

  According to the first invention, since the gap stud arranged between the column and the opening frame is fixed to the column via the connecting member, the separation distance between the column and the opening frame is temporarily a gap stud. Even if it is larger than the width dimension, the gap stud can be fixed to both the vertical frame portion and the column by arranging the gap stud at a position where the side surface thereof overlaps the side surface of the vertical frame portion of the opening frame. That is, the vertical frame portion can be fixed to the column via the gap stud. In this case, since a general-purpose product having a width dimension smaller than the separation distance between the column and the opening frame can be used as the gap stud, the cost burden and work burden on the gap stud can be reduced. Therefore, even if the opening frame is provided apart from the pillar, the opening frame can be suitably fixed to the pillar.

  In a second invention, in the first invention, the stud side fixing part extends between the gap stud and the column by extending in the wall thickness direction from the column side fixing part, and the entry This is fixed to the gap stud.

The gap stud is fixed to one of the inner surfaces of the pair of flanges in the runner.

  In the fifth invention, in the runner, since the gap stud is fixed to only one of the pair of flanges, there is a concern that the fixing strength of the gap stud to the runner is insufficient. Therefore, in order to ensure the supporting strength of the opening frame by the gap stud, it is effective that the gap stud is fixed to the column via the connecting member as in the first invention.

  In a sixth invention, in any one of the first to fifth inventions, the wall portion is an outer wall portion in which a wall heat insulating portion is provided between the pair of wall surface materials, and the wall heat insulating portion is It is provided in a state of entering between the column and the vertical frame portion on the outdoor side of the gap stud.

  According to the sixth aspect of the invention, even in the outer wall portion where the gap between the column and the opening frame is spaced enough to install the gap stud, the wall heat insulating portion enters between the column and the opening frame from the outdoor side. Therefore, it can suppress that the heat insulation performance of an outer wall part falls by the clearance gap between a pillar and an opening frame.

  In a seventh invention, in the sixth invention, a plurality of the connecting members are provided at predetermined intervals in the vertical direction, and the stud side fixing portion of each connecting member is on the indoor side from the wall heat insulating portion, It penetrates between the gap stud and the column.

  In a configuration in which a plurality of connecting members are arranged vertically, if the connecting member enters between the column and the wall heat insulating portion, a gap is generated between the wall heat insulating portion and the column between the connecting members adjacent to each other in the vertical direction. It will be easier. On the other hand, according to the seventh invention, since the connecting member does not enter between the pillar and the wall heat insulating part, a gap is generated between the wall heat insulating part and the pillar, and the outer wall part is formed by the gap. It can suppress that heat insulation performance falls.

  In an eighth invention according to the sixth or seventh invention, the wall heat insulating portion is provided in a gap between the column-side heat insulating portion arranged on the outdoor side of the column and the column and the vertical frame portion. The column side heat insulation portion and the gap heat insulation portion are arranged side by side in the wall width direction and are continuous with each other.

The column-side fixing portion 63 extends from the stud-side fixing portion 62 along the wall width direction, and is fixed to the column 13 with a second screw 66 in a state of being superimposed on the indoor side surface of the column 13.

  Here, a connection structure between the gap stud 47 </ b> B connected by the connection member 61 and the column 13 will be described with reference to FIGS. 2 and 3. FIGS. 3A and 3B are diagrams showing the configuration of the connecting member 61. FIG. 3A is a perspective view of the connecting member 61, and FIG. 3B is an exploded perspective view of the connecting structure of the column 13 and the gap stud 47B.

  As shown in FIG. 3A, the connecting member 61 has a pair of plate portions orthogonal to each other, and one of the plate portions is a stud-side fixing portion 62 and the other is a column-side fixing portion 63. It is said that. The connecting member 61 is formed of a steel material such as a short angle material. The column-side fixing portion 63 is provided with a screw hole 63a for the second screw 66. The screw holes 63 a are round holes, and a plurality of screw holes 63 a are arranged along the boundary portion between the column side fixing portion 63 and the stud side fixing portion 62.

  The stud side fixing portion 62 is provided with a screw hole 62a for the first screw 65. The screw hole 62 a is a long hole extending along the extending direction of the stud side fixing portion 62 from the column side fixing portion 63. The screw holes 62a extend orthogonally to the direction in which the boundary between the column side fixing part 63 and the stud side fixing part 62 extends, and a plurality of screw holes 62a are arranged along the boundary. In this case, the screw hole 62a extends in the horizontal direction along the wall thickness direction. The screw hole 62a of the stud side fixing portion 62 corresponds to the fixing hole.

  As shown in FIG. 2, the stud-side fixing portion 62 of the connecting member 61 enters between the column 13 and the gap stud 47B from the indoor side, and overlaps the side surface of the gap stud 47B. Here, in the wall width direction, the width dimension W1 (for example, 25 mm) of the gap stud 47B is set to be smaller than the separation distance W2 between the vertical frame portion 52a of the window frame 52 and the column 13. Thus, even if the width dimension of the gap stud 47B is not sized to match the distance between the vertical frame portion 52a and the column 13, the connection member 61 and the gap stud 47B are used by using the connection member 61. Thus, the vertical frame portion 52a is fixed to the column 13.

  The clearance distance between the gap stud 47B and the column 13 is larger than the thickness dimension of the stud side fixing portion 62, and the stud side fixing portion 62 is in a state of being overlapped with the side surface of the gap stud 47B. It is separated from the column 13 toward the gap stud 47B. The first screw 65 passes through the screw hole 62a of the stud side fixing portion 62 and protrudes to the column 13 side, and the protruding dimension is larger than the separation distance between the stud side fixing portion 62 and the column 13. ing. In this case, the first screw 65 is attached not only to the stud side fixing part 62 but also to the pillar 13.

  The inner wall surface material 41 is separated from the pillar 13 in the wall thickness direction toward the indoor side, and the pillar side fixing portion 63 of the connecting member 61 is in the separated portion. In this case, the separation distance between the inner wall surface material 41 and the column 13 is smaller than the thickness dimension of the column side fixing portion 63, and the column side fixing portion 63 is separated from the inner wall surface material 41 to the outdoor side.

  The stud side fixing portion 62 of the connecting member 61 does not protrude to the outdoor side from the upper runner 43 and the lower runner 44 in the wall thickness direction. In the connecting member 61, the extension dimension of the stud side fixing part 62 from the column side fixing part 63 is made smaller than the thickness dimension of the gap stud 47B in the wall thickness direction. In this case, the connecting member 61 is disposed on the indoor side with respect to the wall heat insulating portion 48.

  The wall heat insulating part 48 includes a gap heat insulating part 48a that enters from the outdoor side between the column 13 and the vertical frame part 52a of the window frame 52, a column side heat insulating part 48b provided on the outdoor side of the column 13, and a column. It has a main heat insulating part 48c arranged on the opposite side to the gap heat insulating part 48a across the side heat insulating part 48b. These heat insulating portions 48a to 48c are all formed in a plate shape by a foam heat insulating material, and are arranged side by side along the wall width direction in a state where the side surfaces thereof are overlapped with each other. That is, the heat insulating portions 48a to 48c are in a continuous state.

In the gap heat insulating portion 48a, the side surface on the column side heat insulating portion 48b side is overlapped with the side surface of the column 13, and is also overlapped on the side surface of the vertical frame portion 52a, and between the column 13 and the vertical frame portion 52a. Insulates heat. Here, the stud-side fixing part 62 of the connecting member 61 is separated from the gap heat insulating part 48a to the indoor side. In this case, for example, unlike the configuration in which the stud-side fixing portion 62 enters between the column 13 and the gap heat insulating portion 48a, the heat insulating performance by the gap heat insulating portion 48a is not reduced by the stud side fixing portion 62.

  An operation procedure for fixing the gap stud 47B to the column 13 will be briefly described.

  First, the column-side fixing portion 63 of the connecting member 61 is overlapped on the indoor side surface of the column 13, and in this state, the second screw 66 is driven into the column 13 from the screw hole 63 a to fix the connecting member 61 to the column 13. Here, in the wall width direction, the installation positions of the window frame 52 and the gap stud 47B are determined in advance, and the fixing position of the connecting member 61 with respect to the column 13 is set so that the stud side fixing portion 62 contacts the side surface of the gap stud 47B.

  Then, the gap stud 47B is disposed at a position where it abuts against the side surface of the stud-side fixing portion 62, and the first screw 65 is driven toward the stud-side fixing portion 62 from the gap stud 47B side. Here, in the wall thickness direction, the installation position of the inner wall surface material 41 is determined in advance, and the gap stud 47B with respect to the connecting member 61 is placed so that the indoor side surface of the gap stud 47B abuts the outdoor side surface of the inner wall surface material 41. Determine the fixed position. In this case, since the screw hole 62a of the stud side fixing portion 62 extends along the wall thickness direction, the position adjustment of the gap stud 47B with respect to the stud side fixing portion 62 can be easily performed when the first screw 65 is driven. Can do.

  After fixing the gap stud 47B to the column 13 using the connecting member 61, the inner wall surface material 41 and the vertical frame portion 52a are fixed to the gap stud 47B with screws or the like.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the gap stud 47B is connected to the column 13 via the connecting member 61, the gap stud 47B is connected to the column 13 and the window frame even when the separation distance between the column 13 and the window frame 52 is larger than the width dimension of the gap stud 47B. 52 can be fixed to both. In this case, since a general-purpose product having a width smaller than the separation distance between the column 13 and the window frame 52 can be used as the gap stud 47B, the cost burden and work burden on the gap stud 47B can be reduced. it can. Therefore, even if the window frame 52 is provided at a position separated from the pillar 13, the window frame 52 can be suitably fixed to the pillar 13.

  Since the stud side fixing portion 62 of the connecting member 61 enters between the column 13 and the gap stud 47B, the stud side fixing portion 62 does not need to enter between the gap stud 47B and the inner wall surface material 41. For this reason, when the inner wall surface material 41 is fixed to the gap stud 47B with a screw or the like, there is no need to penetrate the stud side fixing portion 62 through the screw or the like. As a result, it is possible to avoid that the stud-side fixing portion 62 becomes an obstacle and a screw or the like for fixing the inner wall surface material 41 cannot be driven into the gap stud 47B in an appropriate state.

  Since the stud-side fixing portion 62 of the connecting member 61 extends in the wall thickness direction, the gap stud 47B is moved along the stud-side fixing portion 62 so that the gap stud 47B is aligned in the wall thickness direction. It can be done easily. Moreover, since the screw hole 62a of the stud side fixing portion 62 is a long hole extending in the wall thickness direction, it is easy to set the driving position of the screw or the like according to the position of the gap stud 47B in the wall thickness direction.

  Since the column-side fixing portion 63 of the connecting member 61 extends along the wall width direction, the column-side fixing portion 63 is moved along the side surface of the column 13 to move the connecting member 61 in the wall width direction. The alignment operation can be easily performed. In this case, the gap stud 47B fixed to the stud side fixing portion 62 of the connecting member 61 can be easily aligned in the width direction. Moreover, since the inner wall surface material 41 is separated from the pillar 13 to the indoor side, the inner wall surface material 41 is not directly fixed to the column 13 with screws or the like. This is a configuration in which the column-side fixing portion 63 is less likely to become an obstacle in fixing the inner wall surface material 41 to the column 13 even if the column-side fixing portion 63 enters between the inner wall surface material 41 and the column 13. It can be said that.

  In the upper runner 43 and the lower runner 44, the gap stud 47B is fixed to only one of the pair of flanges, so that there is a concern that the fixing strength of the gap stud 47B with respect to the runners 43 and 44 is insufficient. However, since the gap stud 47B is fixed to the column 13 via the connecting member 61, even if the fixing strength of the gap stud 47B by the runners 43 and 44 is insufficient, the shortage is compensated by fixing to the column 13. be able to.

  Even in the outer wall part 11 where the pillar 13 and the window frame 52 are spaced apart so that the gap stud 47B can be installed, the wall heat insulating part 48 is inserted between the pillar 13 and the window frame 52 from the outdoor side. Therefore, it can suppress that the heat insulation performance of the outer wall part 11 falls by the clearance gap between the pillar 13 and the window frame 52. FIG.

  Since the stud side fixing portion 62 of the connecting member 61 does not enter between the column 13 and the gap heat insulating portion 48a, the connecting members adjacent to each other in the vertical direction as compared with the configuration in which the stud side fixing portion 62 enters between them. Between 61, it is hard to produce a clearance gap between the pillar 13 and the clearance heat insulation part 48a. Thereby, it can suppress that a clearance gap produces between the pillar 13 and the clearance heat insulation part 48a by presence of the connection member 61, and the heat insulation performance of the outer wall part 11 falls by the clearance gap.

  In the wall heat insulating portion 48, two heat insulating members such as the gap heat insulating portion 48 a and the column side heat insulating portion 48 b are arranged side by side in the wall width direction, so that one heat insulating member arranged on the outdoor side of the column 13 is the column 13. Compared to the configuration entering between the window frame 52 and the window frame 52, the gap heat insulating portion 48 a and the column side heat insulating portion 48 b are easily in close contact with the side surfaces of the column 13 and the window frame 52. Therefore, the heat insulation performance of the outer wall part 11 by the wall heat insulation part 48 can be improved.

  The pillar 13 is included in the lattice pillar. The lattice pillar has a pair of pillars 13 arranged at a predetermined interval in the wall width direction, and a lattice 77 connecting the pillars 13. In the configuration in which the lattice 77 is provided inside the outer wall portion 11, the column-side heat insulating portion 48 b is provided not only on the outdoor side of the column 13 but also on the outdoor side of the lattice 77. Further, the inner wall base 42 is provided on the indoor side of the lattice 77, and the thickness dimension of the inner wall base 42 is smaller than the thickness dimension of the inner wall base 42 of the above-described embodiment. For example, the thickness dimension of the stud 47 provided on the indoor side of the lattice 77 is smaller than the thickness dimension of the gap stud 47B (for example, 25 mm).

  (2) In the above embodiment, the gap stud 47B protrudes upward and downward from the window frame 52. However, the gap stud 47B does not protrude from the window frame 52 in at least one of the upper and lower sides. Good.

Here, the connection runners 81 and 82 have a thickness dimension in the wall thickness direction smaller than the runners 43 to 46 in accordance with the thickness dimension of the gap stud 47B. In this case, in the connection runners 81 and 82, the side surface of the gap stud 47B is overlapped with both of the pair of flanges, and the overlapped portion is fixed by welding or the like. Thus, the gap stud 47B is firmly fixed to the intermediate runners 45 and 46 via the connection runners 81 and 82.

  Short studs 47A are installed above and below the gap studs 47B, and the short studs 47A and the gap studs 47B are arranged side by side.

  Further, the gap stud 47 </ b> B may protrude only upward or downward from the window frame 52. For example, when the gap stud 47 </ b> B protrudes above the window frame 52, the gap stud 47 </ b> B is preferably spanned between the upper runner 43 and the lower connection runner 82. In addition, when the gap stud 47 </ b> B protrudes below the window frame 52, the gap stud 47 </ b> B is preferably spanned between the lower runner 44 and the upper connection runner 81.

  (3) In the above embodiment, the gap stud 47B is provided in a direction in which its long side is orthogonal to the wall width direction. However, the gap stud 47B has its long side in the wall width direction as shown in FIG. You may be provided in the direction extended along. In this configuration, the vertical frame portion 52a of the window frame 52 is formed of gypsum board, and the width dimension in the wall width direction is smaller than the vertical frame portion 52a of the above-described embodiment. The separation distance from the pillar 13 is large. For this reason, it is possible to install the gap stud 47B with the long side extending in the wall width direction.

  In the connecting member 61, the screw hole 63a of the column side fixing part 63 is a long hole extending along the wall width direction, and the screw hole 62a of the stud side fixing part 62 is attached to the first screw 65. It is a round hole. The first screw 65 is not attached to the pillar 13. In this case, in the first screw 65, the length dimension of the protruding portion from the stud side fixing portion 62 to the column 13 side is smaller than the separation distance between the stud side fixing portion 62 and the column 13. Note that if at least one of the screw holes 62a and 63a is a long hole extending in the horizontal direction or in a direction inclined in the horizontal direction, it is easy to change the driving position of the screws 65 and 66.

  (4) In the above embodiment, the gap stud 47B and the stud side fixing portion 62 of the connecting member 61 are screw-fixed using the first screw 65, but the gap stud 47B and the stud side fixing portion 62 are bolts. It may be fixed. For example, a bolt hole is formed in a side surface portion on the connecting member 61 side in the gap stud 47B, and a bolt is inserted into the bolt hole from the hollow portion side of the gap stud 47B, and the bolt is connected to the stud side of the connecting member 61. A configuration is adopted in which the nut is disposed on a side opposite to the gap stud 47B with the fixing portion 62 interposed therebetween. In this configuration, the position of the stud side fixing portion 62 relative to the column 13 can be adjusted along the wall thickness direction by moving the bolt in the wall thickness direction with the screw hole 62a of the stud side fixing portion 62 inserted. It has become easier.

  (5) In the above embodiment, the stud side fixing portion 62 of the connecting member 61 has entered between the column 13 and the gap stud 47B. However, the stud side fixing portion 62 is between the column 13 and the gap stud 47B. It does not have to go in. For example, the stud side fixing part 62 is configured to be disposed on the indoor side or the outdoor side of the gap stud 47B. When the stud side fixing portion 62 is disposed on the indoor side of the gap stud 47B, the stud side fixing portion 62 is overlapped on the indoor side surface of the gap stud 47B, and the overlapped portion is fixed by welding or the like.

In the connecting member 61, the column side fixing portion 63 may be provided on each of the indoor side and the outdoor side of the column 13. For example, the connecting member 61 may include a pair of column side fixing portions 63 that face each other with the stud side fixing portion 62 interposed therebetween.

  (7) The column side fixing portion 63 of the connecting member 61 may be disposed between the column 13 and the gap stud 47B. In this case, it is preferable that the stud-side fixing portion 62 is disposed not on the pillar 13 and the gap stud 47B but on the indoor side or the outdoor side of the gap stud 47B.

  (8) The stud side fixing portion 62 of the connecting member 61 may protrude to the outdoor side from the inner wall base 42. Even in this case, it is preferable that the stud side fixing portion 62 does not enter between the column 13 and the gap heat insulating portion 48a in order to maintain the heat insulating performance of the outer wall portion 11.

  (9) The connecting member 61 may extend in the vertical direction along the column 13 and the gap stud 47B. For example, the connecting member 61 has substantially the same length dimension as the gap stud 47 </ b> B, and is configured to be stretched over the upper runner 43 and the lower runner 44.

  (10) The window 12 may not be a wall opening, but an entrance such as an entrance may be a wall opening.
