Embodiment 1 Hereinafter, a specific embodiment 1 of the present invention will be described with reference to the drawings. In addition, the same or equivalent parts as those of the prior art will be described with the same reference numerals.

First, the structure will be described.
1 is an example in which an opening 7 is formed in the end wall frame 2 as shown in FIG. As the vertical frame at the corner of the end wall frame 2, a vertical frame 102 provided with a box hardware for towing is used. As a result, the side wall frame 2 has a vertical frame 1 between the upper frame 2a and the lower frame 2b.

As shown in FIG. 2, the vertical frame 102 is composed of a pair of wooden bars 102a and 102b each having a thickness (t2b) of 38 mm and arranged via a spacer 26 having a thickness of 38 mm. The thickness t2 is 114 mm. . Wooden bar 102a, 102
In b, through holes 27a and 27b for the bending bolt 24 are formed at positions facing the through holes 25 of the box metal member 22, respectively. Further, four screw holes 28 are formed in the wooden bar 102b for attaching magsa receiving hardware described later.

The box hardware 22 is inserted into the gap 29 between the wooden bars 102a and 102b, and the bending bolt 24 is inserted into the through holes 27b and 2b.
5 and 27a in this order so that the box hardware 2
2 is fixed to the vertical frame 102.

On the other hand, as shown in FIG. 3, the magsa receiving hardware 110 is a steel material (SS400) in which the fixing portion 111 to the vertical frame 102 and the magsa receiving portion 112 for supporting the magsa 8 from below are L-shaped. And a reinforcing rib 113 perpendicular to the L-shaped surface is provided at the center. The height h110 of the magsa metal fitting 110 is smaller than the height h8 of the magsa (normally 140 mm), and the width w110 is equal to the width w2b of the wooden bar 102b. The fixing portion 111 has four through holes 114a for fixing, and the receiving portion 112 has a pair of through holes 114b for fixing the nail.

As shown in FIG. 2, the through hole 114a has
A fixing screw 115 such as a hexagonal head screw screw (coach screw) having a diameter of 9 mm is inserted and screwed into the screw hole 28. As a result, the magsa receiving portion 112 is fixed to the vertical frame 102b. Length L of this fixing screw 115
It is sufficient that 115 can be fixed to the wooden bar 102b without interfering with the box hardware 22. That is, the length of the buried portion in the wooden bar 102b may be shorter than the thickness t2b (38 mm) of the wooden bar 102b and have sufficient strength to support the vertical force. In this example, for example, the length L115 is 38 mm.

With this configuration, as shown in FIGS. 4 and 5, the length L11 of the fixing screw 115 as a fixing member is used.
Since 5 (38 mm) is equal to the thickness t2b (38 mm) of the wooden bar 102b, if the magsa receiving hardware 110 is fixed by the fixing screw 115, only the wooden bar 102b has a margin for the screw head and the thickness of the magsa receiving hardware. And the magsa holder 110 can be fixed. Thereby, the fixing screw 115 as the fixing tool can be securely fixed without interfering with the box hardware 22.

12, the magsa 8 is placed at a slight distance from the magsa holder 110. In this state, the magsa 8 is positioned from below and nailed and fixed by the nail 116.

Unlike the general nailing, the fixing screw 115 is sufficient to bear a shearing load of about 700 kg, so that the load applied to the magsa 8 is vertically It is distributed to the frame 102 and transmitted to the foundation. Thus, even when the end wall frame 2 is used as a load-bearing wall line, it can be fixed without using the magsa holder 9, so that the width w7 of the opening 7 can be made large. [Modification] This modification shows an example in which the height of the opening 7 is adjusted in the first embodiment. In the first embodiment, since the height h110 of the magsa metal fitting 110 is smaller than the height h8 of the magsa 8, as shown in FIG.
The magsa 8 can be provided in contact with the upper frame 2a without limit. Thus, it is understood that the height of the opening 7 can be set freely by changing the length of the vertical bar 2d in the mounting structure of the magsa holder according to the first embodiment.

However, since the magsa receiving metal is fixed by a fixing tool whose length is shorter than the thickness of the frame material, the fixing tool can be attached without interfering with the metal material between the frame materials.

According to the second aspect of the present invention, even when the magsa is mounted across the vertical frames using at least one of the vertical frames having the metal members between the frame members interposed therebetween, the magsa receiving metal members can be used. Since the metal member between the frame members is fixed to one or both of the frame members on the side surfaces where the metal members between the frame members are exposed, the fixing member can be attached without interfering with the metal member between the frame members.

According to the third aspect of the present invention, in the mounting structure of the magsa receiving hardware according to the first or second aspect, the magsa has an opening width formed between the vertical frames. Since the length is shorter than the length, it is possible to attach the magsa metal fitting to the frame material without interfering with the frame material without making a cut for attaching the magsa metal fitting. According to the invention as set forth in claim 4, the metal member between frames is an auxiliary tool for lifting a building unit. Large openings can also be provided in the vicinity of the four corners.

Thus, according to the present invention, it is possible to provide a fixing structure for a magsa receiving metal member without any restriction on a fixing position even in a vertical frame in which metal members between frame materials such as box metal members are interposed.
