Field of the Invention The present invention relates to a wall of a building, in which mounting members are provided, and fixing members are provided at four corners of a wall such as a glass panel, a metal panel, or a slab, and the fixing members are fixed to the mounting members. The present invention relates to a curtain wall having a body attached to a building frame.

[0002]

2. Description of the Related Art As a curtain wall in which a wall is attached to a building frame, for example, a curtain wall disclosed in Japanese Patent Laid-Open No. 6-341209 is known. In this curtain wall, as shown in FIG. 1, a mounting bracket 1 is provided on a building frame, fixing members 3 are provided at four corners of a wall body 2, and the fixing members 3 are attached to the mounting bracket 1.
And the wall 2 is attached to the building frame.

More specifically, as shown in FIG. 2, the mounting bracket 1 has four arms 5 integrally provided at a 90-degree interval radially integrally with a frame mounting portion 4, and the distal end of each arm 5 is provided. In which holes 6 are formed. As shown in FIG. 3, the fixing member 3 is fixed to the arm 5 by screwing a nut 8 through a bolt 8 inserted through a through hole 7 formed at each of the four corners of the wall body 2 through the hole 6 of the arm 5. Things.

[0004]

The above-mentioned curtain wall 2 is attached to the building frame by the fixing member 3 and the mounting bracket 1 at the upper right and left two places and the lower right and left two places. The weight of 2 is supported by either the left and right fixing members 3 on the upper edge or the left and right fixing members 3 on the lower edge.

Since the weight of the wall 2 is supported by one of the upper and lower arms 5 of the left and right mounting brackets 1, the two upper and lower arms 5 of the mounting bracket 1 are supported.
, One half of the weight of the wall 2 acts on one arm 5, the weight of the wall 2 does not act on the other arm 5 of the upper and lower two arms 5, and the other arm 5 2
Is merely supported so as not to move in the out-of-plane direction.

[0006] Because of this, the cross-sectional area of one arm 5 of the mounting bracket 1 is large enough to provide rigidity capable of supporting half the weight of the wall 2, and the arm 5 is thick. The frame mounting portion 4 has a size commensurate with the thickness of the arm 5. Eventually, the size of the arm 5 and the frame mounting portion 4 of the mounting bracket 1 is large enough to support half the weight of the wall 2, so that the mounting bracket 1 becomes large.

[0007] Therefore, when the curtain wall is viewed from the room, the large mounting bracket 1 is visible and the appearance is poor.

The four arms 5 of the mounting bracket 1 are 90
As shown in FIG. 4, in the case of a square wall 2, the distance L ₁ between the fulcrums in the left-right direction (the distance between the through holes 7) is short, and the vertical distance depends on the wall weight. direction deflection amount [delta] ₁ is small.

However, distance between supporting points L ₁ in the lateral direction is longer in the case of the rectangular wall 2 as shown in FIG. 5, the upper and lower due to the wall weight of direction deflection amount [delta] ₁ is large.

[0010] For this, the vertical deflection amount [delta] ₁ due to the wall weight of the case of the rectangular wall body 2 may exceed the allowable value, it is very dangerous.

Therefore, an object of the present invention is to provide a curtain wall capable of solving the above-mentioned problems.

[0012]

According to a first aspect of the present invention, there is provided a mounting bracket comprising a frame mounting portion, four arms provided in the frame mounting portion, and a connecting member connecting upper and lower adjacent arms. A curtain wall in which mounting members are mounted on a building frame, fixing members are mounted on corners of the four walls adjacent to each other, and each of the fixing members is connected to an arm of the mounting member.

According to a second aspect of the present invention, there is provided a frame mounting portion and four arms provided on the frame mounting portion, and the angle between the left and right adjacent arms is larger than the angle between the vertically adjacent arms.
Large, the tip of the four arms on the upper and lower edges of the four walls
A mounting bracket that is close and farther than the left and right vertical edges,
The mounting brackets are attached to the building frame, and fixing members are respectively attached to corners of the four walls adjacent to each other , near the upper and lower edges, and farther than the left and right vertical edges, and the fixing members are attached to the four arms of the mounting bracket. It is a curtain wall connected to each tip.

According to a third aspect of the present invention, there is provided a skeleton mounting portion, four arms provided on the skeleton mounting portion, and a connecting member for connecting arms vertically adjacent to each other, and an angle between the right and left adjacent arms. Is a mounting bracket that is larger than the angle between the vertically adjacent arms, and this mounting bracket is attached to the building frame.
A curtain wall in which fixing members are attached to adjacent corners of two wall bodies, and the fixing members are respectively connected to tips of four arms of the mounting bracket.

[0015]

According to the first aspect of the present invention, the weight of the wall acting on one of the vertically adjacent arms of the mounting bracket acts on the other arm via the connecting member, so that the two arms of one mounting bracket are provided. Will disperse and support half the weight of the wall.

Accordingly, the cross-sectional area of the arm of the mounting bracket may be a size capable of supporting one-fourth the weight of the wall, so that the arm becomes smaller, and the smaller the arm, the smaller the body mounting portion.

According to the second aspect of the present invention, the tips of the four arms of the mounting bracket are close to the upper and lower edges of the wall and farther from the left and right vertical edges, and the mounting position of the fixing member of the wall is closer to the upper and lower edges. It becomes far from the right and left vertical edges.

As a result, the distance between the fulcrums in the left-right direction of the wall is smaller than the total length in the left-right direction, so that the amount of vertical deflection due to the weight of the wall is reduced.

According to the third aspect of the present invention, the weight of the wall acting on one of the arms vertically adjacent to the mounting bracket acts on the other arm via the connecting member. Half of the weight of the wall will be dispersed and supported. Also, the tips of the four arms of the mounting bracket are close to the upper and lower edges of the wall body and farther from the left and right vertical edges, and the mounting positions of the fixing members of the wall body are closer to the upper and lower edges and far from the left and right vertical edges.

Accordingly, the arm cross-sectional area of the mounting bracket may be large enough to support one-fourth the weight of the wall, so that the arm is small, and the arm is small, so that the frame mounting part is also small. Further, since the distance between the fulcrums in the left-right direction of the wall is smaller than the entire length in the left-right direction, the amount of vertical deflection due to the weight of the wall is reduced.

[0021]

As shown in FIG. 6, mounting brackets 11 are fixed to the outdoor surface of a building frame, for example, a vertical steel frame 10 spaced apart in the left-right direction, with a spacing in the vertical direction. At the four corners of the wall, for example, the glass plate 12, the fixing members 1
3 are provided, and four fixing members 13 provided at one corner of four glass plates 12 adjacent vertically and horizontally are fixed to the one mounting bracket 11.

As shown in FIGS. 7, 8, and 9, the mounting bracket 11 includes a frame mounting portion 20, four arms 21, and a connecting member 22 for connecting two vertically adjacent arms 21. Become. The frame mounting portion 20 is cylindrical and has a bolt hole 23. The bolt hole 23 is screwed into a bolt 24 fixed to the vertical reinforcing bar 10, and the mounting bracket 11 is fixed to the vertical reinforcing bar 10.

The length of the four arms 21 is the same, a through hole 25 is formed at the tip end, and the angle θ ₁ between the two right and left adjacent arms 21 is the two vertically adjacent two arms 21. It is larger than the angle θ ₂ between.

The fixing member 13 has a holder 30 and a bolt 31, and the holder 30 is attached to the through hole 3 of the glass plate 12.
2 into the holder 30 from the outside,
Are screwed together to fix the holder 30 to the glass plate 12. The bolt 31 is inserted into the through hole 25 of the arm 21, screwed a pair of nuts 34, and clamps the arm 21 to fix the bolt 31 to the arm 21.

As described above, the weight of the glass plate acting on one of the arms 21 vertically adjacent to the mounting bracket 11 also acts on the other arm 21 via the connecting member 22, and is half the weight of the glass plate 12. Is supported by the two arms 21. Eventually, half of the weight of the glass 12 is dispersed and supported by the arm 21 on one side of the one mounting bracket 11.

For example, in FIG. 7, when the weight is supported by suspending the glass plate 12 with a fixing member 13 fixed to the upper edge of the glass plate 12, the lower arm 21 vertically adjacent to the glass plate 12 holds the glass plate 12. Half the weight acts, and half the weight acting on the lower arm 21 acts on the upper arm 21 via the connecting member 22.

As described above, the cross-sectional area of the arm 21 is smaller than the half weight of the glass plate 12 (approximately 1/1).
4 weight) and a size that can provide rigidity that can support
The arm 21 can be made thin. When the arm 21 becomes thinner, the frame mounting portion 20 can be made smaller.

Therefore, since the mounting bracket 11 is small, when the curtain wall is viewed from inside the room, the mounting bracket 11 becomes small.
Is not noticeable and does not look good.

Since the angle θ ₁ between the right and left adjacent arms 21 is larger than the angle θ ₂ between the vertically adjacent arms 21, the tip of the arm 21 is close to the upper and lower edges of the glass plate 12, Since it is farther than the vertical edge, the fixing member 1
The position where the glass plate 12 is fixed in 3 (the position of the through hole 32 of the glass plate 12) is close to the upper and lower edges of the glass plate 12, and is farther than the left and right vertical edges.

The smaller this manner, the lateral direction distance between supporting points L ₁ of the glass plate 12 as shown in FIG. 10 as compared with the lateral direction length. For example, smaller than the conventional case shown in FIG. 5, the vertical distance between supporting points L ₂ is the same as in the conventional case shown in FIG.

[0031] Thus, the vertical deflection amount [delta] ₁ due to the wall weight of the case of the rectangular glass plate 12 becomes smaller than the conventional case shown in FIG. 5, may not exceed the allowable value.

[0032]

According to the first aspect of the present invention, the weight of the wall acting on one of the upper and lower arms adjacent to the mounting bracket acts on the other arm via the connecting member.
One arm will distribute and support half the weight of the wall.

Accordingly, the cross-sectional area of the arm of the mounting bracket may be a size capable of supporting one-fourth the weight of the wall, so that the arm is reduced, and the smaller the arm, the smaller the frame mounting portion.

Therefore, since the mounting bracket is small,
The mounting bracket does not stand out when the curtain wall is viewed from the room, and the appearance is improved.

According to the second aspect of the invention, the tips of the four arms of the mounting bracket are close to the upper and lower edges of the wall and farther from the left and right vertical edges, and the mounting position of the fixing member of the wall is closer to the upper and lower edges. It becomes far from the right and left vertical edges.

As a result, the distance between the fulcrums in the left-right direction of the wall is smaller than the total length in the left-right direction, so that the amount of vertical deflection due to the weight of the wall is reduced.

Therefore, in the case of a rectangular wall, the amount of deflection in the vertical direction due to the weight of the wall does not exceed an allowable value, which is safe.

According to the third aspect of the present invention, the weight of the wall acting on one of the arms vertically adjacent to the mounting bracket acts on the other arm via the connecting member. Half of the weight of the wall will be dispersed and supported. Also, the tips of the four arms of the mounting bracket are close to the upper and lower edges of the wall body and farther from the left and right vertical edges, and the mounting positions of the fixing members of the wall body are closer to the upper and lower edges and far from the left and right vertical edges.

Accordingly, the arm cross-sectional area of the mounting bracket may be large enough to support one-fourth the weight of the wall, so that the arm is reduced, and the smaller the arm, the smaller the frame mounting portion. Since the metal fittings are small, the mounting metal fittings do not stand out when the curtain wall is viewed from the room, and the appearance is improved. Also, since the distance between the fulcrums in the left-right direction of the wall is smaller than the total length in the left-right direction, the amount of deflection in the vertical direction due to the weight of the wall is small, and in the case of a rectangular wall, the amount of deflection in the vertical direction due to the weight of the wall is small. It is safe without exceeding allowable values.
