Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of the frame of the outer wall of a house.

[Background technology]

The wall is formed between the pillars 1 and 1 erected on the foundation 10 etc., but in order to form an opening 11 such as a window in the wall, the subframe 5 is installed between the pillars 1 and 1. It may be erected on a foundation 10 or the like in one room. The column material 6 of the subframe 5 is connected to the lower surface of the beam 2 by the subframe fixing hardware 4 so that the horizontal force applied to the column 1 as indicated by the arrow a in FIG. 1 is also supported by the subframe 5. be. However, if a vertical force, such as a live load or a fixed load, as indicated by arrow b in Figure 1 is applied to the pillars 6 of the subframe 5 via the subframe fixing hardware 4, the pillars 6 of the subframe 5 will buckle. Therefore, there is a problem in completely fixing the column material 6 of the subframe 5 to the beam 2 with the subframe fixing hardware 4.

[Purpose of invention]

The present invention has been made in consideration of the above points, and aims to provide a wall frame structure in which only horizontal forces are transmitted to the subframe and no vertical forces are transmitted.

[Disclosure of invention]

However, the structure of the wall frame according to the present invention has columns 1,
A subframe fixing hardware 4 with a support angle 3 having an L-shaped cross section is attached to the lower surface of the beam 2 suspended horizontally between the pillars 1 and 1, and the pillar material 6 of the subframe 5 is erected approximately vertically between the pillars 1 and 1. A connecting rod 7 is made to protrude upward from the upper end, and an insertion hole 8 having an inner diameter slightly larger than the outer diameter of the connecting rod 7 is provided in the support angle 3 and is open vertically. The present invention is characterized by being inserted into the body from below, and with this configuration, the above object has been achieved.The present invention will be described in detail below with reference to examples.

FIG. 4 shows the subframe mounting hardware 12 fixed to the upper end of the pillar material 6 of the subframe 5.
Connecting rods 7, 7 made of round steel or the like are fixed to the inner surface of the main body 21, which has a U-shaped horizontal cross section, by welding or the like so as to protrude upward. A male thread 13 is cut into the upper end of the connecting rod 7. 14 is a bolt hole. As shown in FIG. 3, the subframe mounting hardware 12 is fitted into the upper end of the column 6 of the subframe 5 made of H-shaped steel or the like via a spacer 15, and is secured to the subframe 5 by bolts and nuts.
It is fixed to the upper end of the pillar material 6. FIG. 5 shows the subframe fixing hardware 4, in which a support angle 3 with an L-shaped cross section is fixed to the bottom surface of the base plate 16 by welding or the like, and reinforcing plates 17 are attached on both sides.
It is formed by attaching it by welding etc. Insertion holes 8 are bored in the horizontal piece of the support angle 3 at equal intervals to the connecting rods 7 and having an inner diameter slightly larger than the outer diameter of the connecting rods 7. For example, the diameter of the connecting rod 7 is
If the diameter is 22 mm, the inner diameter of the insertion hole 8 is set to 23 mm. 18 is a bolt hole. The subframe fixing hardware 4 is fixed to the lower surface of the beam 2 with bolts and nuts, as shown in FIGS. 2a and 2b.

As shown in Fig. 1, the columns 1, 1 are erected with their lower ends fixed to the foundation 10, etc., and the beam 2 is suspended horizontally and fixed to both columns 1, 1. There is. The subframe 5 includes a pair of pillar members 6,
It is formed by installing horizontal members 20, 20 between the upper and lower parts of the pillars 6, and is arranged between the above-mentioned columns 1, 1, and the lower ends of the pillars 6, 6 are fixed to anchor bolts etc. on the foundation 10. It has been erected. When the subframe 5 is erected in this way, the upper part of the connecting rod 7 at the upper end of the column 6 is inserted into the insertion hole 8 of the subframe fixing hardware 4 and loosely fitted, as shown in FIGS. 2a and 2b. It is something. A locking nut 19 is screwed onto the male screw 13 at the upper end of the connecting rod 7. The subframe 15 may be attached on the beam 2 in the same manner. In this case, when a horizontal force is applied to the column 1 and the beam 2 as shown by the arrow a in Fig. 1, this horizontal force is absorbed by the subframe fixing hardware 4 when the connecting rod 7 is inserted into the insertion hole 8. The horizontal force is transmitted to the subframe 5 and can be received by the subframe 5, causing the subframe 5 to act as a brace. Also, even if the beam 2 is deflected downward due to vertical force as shown by arrow b in FIG. Since the rod 7 is in a free state in the vertical direction, vertical force is not transmitted to the column 6, and buckling of the column 6 is prevented.

[Effect of idea]

As mentioned above, in the present invention, an insertion hole with an inner diameter slightly larger than the outer diameter of the connecting rod is provided in the support angle of the subframe fixing hardware, opening upward and downward, and protruding upward from the upper end of the column material of the subframe. The upper part of the connecting rod was inserted into the insertion hole and the subframe was connected to the beam between the columns using the subframe fixing hardware, so the horizontal force applied to the columns was absorbed by the subframe fixing hardware. This force is transmitted to the subframe and can be received by the subframe, and the vertical force is not transmitted to the subframe by the subframe fixing hardware, preventing buckling of the subframe columns. .
