Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of walls such as the outer walls of houses.

[Background technology]

The wall is formed between the pillars 1 and 1 erected on the foundation 10, etc., but when an opening such as a window is formed between the pillars 1 and 1, braces are used to reinforce this opening. I can't do something like that. Therefore, as shown in Fig. 1, a load-bearing wall 3 is erected on the foundation 10 between the columns 1 and 1 below the beam 2 constructed between the columns 1 and 1, and the load-bearing wall 3 is used to open the opening. In some cases, it may be done to form a In this case, the horizontal force applied to the column 1 as indicated by the arrow a in FIG. 1 can be supported by the load-bearing wall 3 as well. However, in the case of the structure shown in Fig. 1, in addition to receiving the above-mentioned horizontal force, the vertical force shown by the arrow b in Fig. 1, such as live load and fixed load, is also applied to the load-bearing wall 3 by the beam 2. There has been a problem in that the application of this vertical force to the vertical frame 4 at the end of the wall 3 may cause the vertical frame 4 to buckle.

[Purpose of invention]

The present invention has been developed in view of the above points, and is a wall that transmits only horizontal force to the load-bearing wall and does not transmit vertical force, thereby preventing buckling of the vertical frame of the load-bearing wall. The purpose is to provide a structure for

[Disclosure of invention]

However, in the wall structure according to the present invention, a load-bearing wall 3 is erected between the columns 1 and 1 at a position below the beam 2 constructed between the columns 1 and 1 with a gap between the lower surface of the beam 2 and the lower surface of the beam 2. However, at the position where the horizontal frame 5 at the upper end of the load-bearing wall 3 is constructed, a metal plate 8 is interposed between the vertical frame 4 at the side end of the load-bearing wall 3 and the side surface of the column 1, and other parts of the vertical frame 4 are This invention is characterized by forming a gap between the vertical frame 4 and the pillar 1, and connecting the vertical frame 4 and the pillar 1 via a metal plate 8. With this structure, the present invention achieves the above object. The present invention will be described in detail below with reference to Examples.

The load-bearing wall 3 is formed by constructing L-shaped steel horizontal frames 5, 5 between the upper and lower parts of the left and right H-shaped steel vertical frames 4, 4, and by stretching panel boards. A bolt through hole 6 is bored in the upper end of the holder. The columns 1 and 1 are erected on the foundation 10 by fixing their lower ends to the foundation 10 with anchor bolts, and a beam 2 such as a floor beam is installed between the middle stages of the columns 1 and 1. It has been erected. A bolt through hole 7 is bored on the inner surface of the column 1 at a position below the beam 2.

The load-bearing wall 3 is disposed below the beam 2 between the columns 1, 1, as shown in FIG. 2, and its lower end is fixed onto the foundation 10 or the like with anchor bolts or the like. A gap is provided between the upper end of the load-bearing wall 3 and the lower surface of the beam 2 to prevent the beam 2 from coming into contact with the upper end surface of the load-bearing wall 3. A metal plate 8 is inserted between the upper end of the vertical frame 4 of No. 3 and the column 1, and the vertical frame 4 is
and bolt through holes 6, 7 of column 1 and metal plate 8
The upper end of the load-bearing wall 3 is fixed to the column 1 by the vertical frame 4 by passing a bolt through the bolt through hole 9 and screwing it with a nut. Therefore, a gap is formed between the vertical frame 4 and the column 1 as shown in FIG. 2 except for the metal plate 8, and the force from the column 1 is transmitted only through the metal plate 8. It is transmitted to the vertical frame 4 and supported by the horizontal frame 5 installed on the upper end of the vertical frame 4. In the embodiment shown in Fig. 2, the load-bearing wall 3 is installed over almost the entire area between the pillars 1, 1, but the load-bearing wall 3 is installed only in a part between the pillars 1, 1. , the load-bearing wall 3 may be connected only to one column 1. Further, a load-bearing wall 3 can be attached above the beam 2 in the same manner. However, when a horizontal force is applied to the column 1 as shown by the arrow a in Fig. 2, this force is directly transmitted to the load-bearing wall 3 through the metal plate 8, and the load-bearing wall 3 also acts in this horizontal direction. As the force is supported, the load-bearing wall 3 acts as a brace. In addition, even if a vertical force is applied to the beam 2 and the beam 2 is deflected downward as shown by arrow b in Figure 2, there is a gap between the beam 2 and the load-bearing wall, so the vertical force is applied to the load-bearing wall 3. is not transmitted, and it is possible to prevent the vertical frame 4 of the load-bearing wall 3 from buckling due to vertical force. Note that the upper end of the load-bearing wall 3 may not be connected to the beam 2, but in order for the load-bearing wall 3 to receive the horizontal force more effectively, the upper end of the load-bearing wall 3 may be connected to the beam 2 as shown in FIG. It is preferable that the upper end of the load-bearing wall 3 is connected to the upper end of the load-bearing wall 3. That is, a mounting hardware 12 with a connecting rod 11 projecting upward is fixed to the upper end of the vertical frame 4 of the load-bearing wall 3 with bolts and nuts, and an L-shaped angle 13 is attached to the bottom surface of the base plate 14. is fixed to the lower surface of the beam 2 with bolts and nuts, and an insertion hole 16 with an inner diameter slightly larger than the outer diameter of the connecting rod 11 is provided in the horizontal piece of the angle 13 (for example, if the outer diameter of the connecting rod 11 is 22 mm, the insertion hole 16 is When installing the load-bearing wall 3 between the pillars 1 and 1 as described above, insert the connecting rod 11 into the insertion hole 16 and attach the load-bearing wall to the beam 2 using the fixing hardware 15. This connects the upper ends of 3. A retaining nut 18 is screwed into the male threaded portion 17 at the upper end of the connecting rod 11. In this case, if a force is applied in the horizontal direction of the arrow a in Figure 2, the fixed hardware 1
The force is transmitted by the beam 2 to the vertical frame 4 of the load-bearing wall 3 through the connecting rod 11 inserted into the insertion hole 16 of the load-bearing wall 3, and the horizontal force is received by the load-bearing wall 3. Furthermore, when a force is applied in the vertical direction indicated by the arrow b in FIG.
1 is inserted in a free state in the vertical direction, so that vertical force is not transmitted to the vertical frame 4 of the load-bearing wall 3. Since the connecting rod 11 is freely inserted into the insertion hole 16 in the vertical direction in this way, it is also possible to cope with variations in accuracy between the members.

[Effect of idea]

As mentioned above, in the present invention, the load-bearing wall is erected below the beam with a gap between it and the lower surface of the beam, and the vertical frame of the load-bearing wall is connected to the side surface of the column. Therefore, when a horizontal force is applied to a column, this force is received by the load-bearing wall and the load-bearing wall acts as a brace, and the vertical force is applied to the load-bearing wall between the beam and the load-bearing wall. It is not transmitted to the load-bearing wall due to the gap, and there is no fear that buckling will occur in the vertical frame of the load-bearing wall. In addition, at the position where the horizontal frame at the upper end of the load-bearing wall is installed, a metal plate is interposed between the vertical frame at the side end of the load-bearing wall and the side of the column to create a gap between other parts of the vertical frame and the column. At the same time, the vertical frame and the column are connected through the metal plate, so the horizontal force applied to the column is transmitted to the vertical frame only at the part where the horizontal frame is installed through the metal plate. There is no fear that the horizontal force applied to the column will be received only by the vertical frame and deform the vertical frame.
