DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a wall panel, and more particularly to a structure for fixing a wall panel to be attached to a building unit manufactured in a factory to a column frame for the wall panel.

[0002]

2. Description of the Related Art In order to support a wind load applied to a wall panel having an outer wall material and a wall frame fixed to the outer wall material and the load of the wall panel itself, the wall frame of the wall panel is fixed to a column frame. However, in Japanese Utility Model Publication No. 59-67408,
The structure in which the column frame is simply overlapped with the wall frame in the wall thickness direction and connected is shown.

[0003]

In the fixing structure described in the above-mentioned publication, since the column frame and the wall frame overlap each other, the size in the wall thickness direction is large, and the sectional modulus is small.

An object of the present invention is to provide a wall panel fixing structure capable of obtaining a large section modulus in a limited space in a wall thickness direction.

SUMMARY OF THE INVENTION The present invention relates to a fixing structure for a wall panel having an outer wall material and a wall frame fixed to the outer wall material, comprising two side edges and an edge extending between the two side edges. The wall frame has a first side sandwiched between the outer wall material and an end side of the column frame, and a second side extending from the first side. The sides are
The column frame and the first side are coupled to the column frame so as to form a closed space in a horizontal cross section.

[0006]

[Operation and Effect] The area of the wall frame and the column frame overlap in the wall thickness direction in the horizontal section, that is, in the direction perpendicular to the outer wall material, and a closed space is formed in the horizontal section. Large cross-sectional performance can be ensured within a limited space in the wall thickness direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The wall panel fixing structure is a structure for fixing a wall panel 10 to a column frame 12 connected to a unit (not shown).

The wall panel 10 has an outer wall material 14 formed to a predetermined size by ceramic siding such as a noncombustible board, and a wall frame 16 fixed to the outer wall material 14.

The pillar frame 12 has two sides 18 and an end 19 extending between the sides.

In the embodiment shown, the column frame 12 has a flange side 20 extending from each side 18 in a direction opposite to the end 19 in parallel with the outer wall material 14 and has a so-called hat cross section. Two steel materials 21 having shapes are overlapped symmetrically with the flange sides 20 abutting each other to form a closed space in a horizontal section. Alternatively, the column frame 12 can be formed by a single hat-shaped steel material 21;
Further, it can be formed of a steel material bent so that its horizontal cross section has a U-shape.

The wall frame 16 is formed of a steel material and has a first side 24 and a second side 25 fixed to the outer wall member 14 by bonding or screwing, and the first side 24 is formed of the outer wall member 14. And the end 19 of the column frame 12. The second side 25 extends from the first side 24 and is coupled to the column frame 12 so as to form a closed space in a horizontal cross section in combination with the column frame 12 and the first side 24.

In the illustrated embodiment, the second
The side 25 is formed such that its horizontal cross section has an L-shape. Have been. as a result,
The second side 25, together with the column frame 12 and the first side 24, forms a closed space 30 in a horizontal section.

In order to mount and fix the wall panel 10 to the column frame 12, the two wall panels 10 are arranged with a space 32 between the outer wall members 14, and the flange portion 26 of the second side 25 of the wall panel 16 is fixed. The second side 25 is joined to the column frame 12 by rivets 28 while overlapping the flange side 20 of the column frame 12. In this case, the edge 19 of the pillar frame 12
It is preferable that a waterproof material 34 be interposed between the first frame 24 and the first side 24 of the wall frame 16.

According to the illustrated embodiment, two steel materials 21 are press-formed in a hat shape, and the hat-shaped cross sections are arranged so as to face each other to form a closed space in the column frame 12 in a horizontal cross section. Because the pillar frame 1
2, the rivet holes can be provided in the flange side 20 by press molding, so that workability can be improved.

Furthermore, according to the embodiment shown, the space or joint 32 created at the abutting portion of the two wall panels 10.
Is the space 3 that will be connected when the waterproof material 34 disappears.
Since 0 is surrounded by the steel material of the column frame 12 and the steel material of the wall frame 16, it is possible to prevent the intrusion of flame from the outside to the inside of the wall panel 10. Further, since the first side 24 of the wall frame 16 can be lengthened, the position of the screw 40 for fixing the outer wall member 14 can be set at a position away from the edge of the outer wall member 14, and A firm fixation is possible.

The column frame 12 is made of a single hat-shaped steel material 21.
, The wall frame 16 can have the same structure as in the previous embodiment. Further, when the column frame is made of a U-shaped steel material, the second side 25 of the wall frame 16 is provided with a contact side extending inward from the flange portion 26, that is, with a contact side extending farther with respect to the first side 24. It is formed in a crank shape, and the contact side and the column frame can be connected. Thus, the second side of the wall frame is combined with the column frame and the first side of the wall frame to form a closed space in a horizontal cross section.
