Regardless of the type of window, it is possible to maintain good earthquake resistance.

  In particular, the cross-sectional area of the beam material is increased (beam back 150 mm × beam width 120 mm) to make it difficult for the beam material itself or the joint between the beam material and the column material to break down, or to fix the structural plywood or By increasing the pitch of the screws (at a rate of 9 per meter), the load on the bearing wall is prevented from rising excessively, making it difficult for the column material to bend and breaking, thereby greatly improving the elongation capacity of deformation. A tenacious structure.

  In addition, the horizontal frame material that spans between the upper and lower ends of adjacent column members must be less likely to break due to the large force that is difficult to act even when subjected to a horizontal force during an earthquake or typhoon. Therefore, the cross-sectional area is made smaller than the beam material used as the window lintel or window sill, thereby reducing the material cost.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the load-bearing wall 1 of a wooden house according to an embodiment of the present invention is used to wind a window as a horizontal frame member between upper end portions of adjacent column members 3 constituting the shaft assembly 2. A beam member 11 serving as a window base is bridged between the intermediate portions of the adjacent column members 3 constituting the shaft assembly 2, and the lower end portions of the adjacent column members 3 constituting the shaft assembly 2. Between them, a base material 12 as a horizontal frame member is bridged, and two openings 13 and 14 are partitioned and formed between the adjacent column members 3 constituting the shaft assembly 2 in the vertical direction. As shown in FIG. 3, the upper end portion of the column member 3 is fixed to the beam member 4 constituting the shaft assembly 1 via a column head metal 15, and the lower end portion of the column member 3 is interposed via a column base metal 16. The cloth base 5 is fixed to the rising part.

  The window lintel 10 is made of a square bar having a vertical cross section height of 60 mm and a horizontal width of 120 mm, and both ends thereof are fixed to the upper ends of the adjacent column members 3 with nails or screws. The base material 12 is made of a square material having a vertical cross section height of 60 mm and a horizontal width of 120 mm, similar to the window lintel 10, and both ends thereof are fixed to the lower end portion of the adjacent column material 3 with nails or screws. . On the other hand, the beam member 11 serving as the window base is made of a square member having a vertical cross-section height (beam back) of 150 mm and a lateral width (beam width) of 120 mm, and an intermediate portion of the column member 3 adjacent to both ends thereof. Are fastened to each other through a joint hardware 20.

  As shown in FIG. 4, the metal joint 20 is formed by bending a metal plate into a U shape in a plan view, and has a plate-like column-side fixing portion 23 and both ends along the vertical direction of the column-side fixing portion 23. And a pair of left and right plate-like beam-side fixing portions 24 protruding from the portion. A plurality of bolt insertion holes 25 are formed in the column side fixing portion 23 at intervals in the vertical direction. A substantially V-shaped pin receiving groove 26 that opens upward and a pin insertion hole 27 are formed in the beam-side fixing portion 24 with an interval in the vertical direction.

  Tightening of the column member 3 using the joint hardware 20 and the beam member 11 serving as a window base is performed as follows. Note that a pair of bolt through holes 30 are formed in the middle portion of the column member 3 at intervals in the vertical direction. A pair of slits 31 that open to the upper and lower surfaces and the end surface of the beam member 11 are formed at intervals in the horizontal direction. Furthermore, a pair of pin through-holes 32 are formed at the end of the beam member 11 so as to be orthogonal to the slit 31 with a space in the vertical direction.

  First, the column-side fixing portion 23 of the metal fitting 20 is brought into contact with the intermediate portion of the column member 3 such that the bolt insertion hole 25 is overlapped with the bolt through hole 30 of the column member 3. From this state, the bolt 35 is inserted into the bolt through hole 30 and the bolt insertion hole 25 that are coincident with each other, and a nut 36 is screwed onto the tip of the bolt 35 and tightened to join the intermediate portion of the column member 3. The column side fixing part 23 of the hardware 20 is fixed. Subsequently, the end portion of the beam member 11 is brought into contact with the intermediate portion of the column member 3 so that the beam-side fixing portion 24 of the metal joint 20 is inserted into the slit 31. At this time, the drift pin 37 is inserted in advance into the pin through hole 32 on the upper side of the beam member 11, and the drift pin 37 is dropped into the pin receiving groove 26 of the beam side fixing portion 24, thereby lowering the beam member 11. The beam member 11 is temporarily fixed to the beam-side fixing portion 24 so that the pin through-hole 32 and the pin insertion hole 27 of the beam-side fixing portion 24 coincide with each other. From this state, the end of the beam member 11 is fixed to the beam-side fixing portion 24 of the metal joint 20 by inserting the drift pin 37 through the pin through hole 32 and the pin insertion hole 27 that coincide with each other. As a result, the intermediate portion of the column member 3 and the end portion of the beam member 11 are fastened together via the bonding hardware 20.

  As shown in FIGS. 1 and 3, the upper opening 13 is formed of a rectangular frame-shaped portion surrounded by the adjacent column member 3, the window lintel 10, and the beam member 11 serving as a window base. A window 40 is installed in the part 13. That is, the upper opening 13 is a window installation opening.

  As shown in FIGS. 1 and 2, the window 40 is a sliding window in which a pair of shojis 42 are slidably attached to a window frame 41, and is fitted into the window installation opening 13 to fix it with a nail or a screw. Installed by fixing. The window 40 is not limited to the sliding window, and may be any type of window such as a fitting window, a raising / lowering window, an outer window, a folding window, and a bay window.

  As shown in FIG. 1 and FIG. 3, the lower opening 14 is composed of a rectangular frame-shaped portion surrounded by the adjacent column member 3, the beam member 11 serving as the window base, and the base member 12. In the opening 14, a semi-column 45 and an inter-column 46 are provided between the beam member 11 and the base material 12, and a rectangular structural plywood 50 is attached. The upper and lower end portions of the half pillar 45 and the intermediate pillar 46 are fixed to the beam member 11 and the base member 12 by nails or screws, but may be fixed via a joint hardware.

  The structural plywood 50 is driven by nails 51 at a rate of about 9 per 1 m (about 120 mm pitch) along its peripheral edge, so that the lower opening 14, that is, the adjacent column 3, the beam that becomes the window base Nailed and fixed to the material 11 and the base material 12. Further, a nail 51 is appropriately driven into a portion of the structural plywood 50 where the half pillar 45 and the interposition pillar 46 abut, and is fixed to the half pillar 45 and the intermediary pillar 46 with a nail. A small gap 47 is provided between the beam member 4 constituting the shaft assembly 2 and the window lintel 10, and the beam member 4 and the window lintel 10 are formed so as to close the gap 47. A strip-like plywood 52 is fixed with a nail.

  Thus, in the above-mentioned load-bearing wall 1, the beam material 11 which is a structural material having a large cross-sectional area is used as a window base, and both ends of the beam material 11 are intermediate between adjacent column members 3 in the shaft set 2. Since it is tightly coupled to the portion via the joint hardware 20, it is difficult for the beam member 11 itself or the joint portion between the beam member 11 and the column member 3 to be broken. Moreover, since the structural plywood 50 is fixed to the lower opening 14 with a nail pitch being rough (at a pitch of about 120 mm), the load on the bearing wall 1 is prevented from excessively increasing, It is possible to lighten the bending load of the column member 3 (to prevent excessive force from acting on the intermediate portion of the column member 3 from the joint between the beam member 11 and the column member 3) While preventing, it is possible to increase resistance to horizontal force during earthquakes and typhoons. As a result, the structure has a tenacious structure that greatly improves the elongation capacity of deformation, and can maintain good earthquake resistance.

  In addition, a large force acts on the window lintel 10 and the base material 12 as horizontal frame members spanned between the upper and lower ends of the adjacent column members 3 even when receiving horizontal force during an earthquake or typhoon. The cross-sectional area is made smaller than that of the beam member 11 serving as a window base because it is difficult to destroy and the material cost is reduced.

  In addition, although not shown in figure, except the part which installed the window 40, the interior material is affixed on the indoor side, and the exterior material is affixed on the outdoor side.

  FIG. 5 shows the shear test result of the load bearing wall 1 described above, and FIG. 6 shows the shear test result of the load bearing wall of the comparative example. As shown in FIG. 7, in the bearing wall of the comparative example, the window base 11A is made of a square member having a vertical cross section height (beam back) of 60 mm and a horizontal width (beam width) of 120 mm, and both end portions thereof are adjacent to each other. The structural plywood is nailed and fixed to the lower opening 14 by driving nails at a pitch of about 60 mm along the peripheral end portion. Other configurations are the same as those of the load bearing wall 1 described above. In the shear test, a load in the horizontal direction was applied to the beam member 4 constituting the shaft assembly 2, and the deformation angle with respect to the load at this time was measured. This measurement was performed three times.

  From this shear test result, in the load bearing wall 1 described above, the maximum load is suppressed, it is tenacious without being broken until a large deformation occurs, and a short-term allowable shear strength can be sufficiently ensured. It was confirmed that the maximum load is increased in the bearing wall, and the deformation does not extend and brittle fracture occurs, and the short-term allowable shear strength is greatly reduced. The short-term allowable shear strength is the yield load (Py), ultimate load and deformation performance (Pu × 0.2 / Ds), 2/3 of the maximum load (2/3 × Pmax), and deformation angle 1/120. It is determined from the minimum value of the load.
