Abstract

PROBLEM TO BE SOLVED: To provide a louver unit bringing about a reduction in deformations, such as torsion, camber, etc., which are caused to a blade when the upper and lower frames of a mounting frame are moved in the direction opposite to an in-plane one. SOLUTION: In the louver unit, the mounting frame 6 is mounted with a blade unit 7 wherein the blade 21 is mounted on a blade unit frame 20, the longitudinal and upper frame members 22 and 23 of the unit frame 20 are respectively fixed to the longitudinal and upper frames 12 and 10 of the mounting frame 6, and a lower frame 11 and a lower frame member 24 are coupled in such a manner as to be able to slide in the in-plane direction. Consequently, the deformations, such as torsion, camber, etc., of the blade 21 are reduced because a great force does not act on the blade 21 when the frames 10 and 11 are moved in the direction opposite to the in-plane one.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rattling unit and a building outer wall provided with the rattling unit.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No.
As shown in Japanese Patent No. 9235, there has been proposed a unit frame in which a plurality of blades are attached at intervals in the vertical direction. As a building outer wall, what is called a curtain wall in which an outer wall material such as a PC board, a glass unit, or a window unit is attached to a building frame has been proposed.

[0003]

In the above-mentioned rattling unit, when the upper frame and the lower frame of the unit frame move in opposite directions in the plane, the vertical frame becomes oblique, so that the blade attached to the vertical frame is impossible. A large force acts, and deformation such as twisting and warping occurs.

[0004] By attaching the above-mentioned garbage unit to an outer wall material constituting an outer wall of a building, an outer wall of the building provided with the gallery unit can be formed. In this case, when the outer wall material attached to the upper floor and the outer wall material attached to the lower floor are interlayer-displaced, the gallery unit moves together with one outer wall material in the in-plane direction, so that there is no problem. However, in the case described above, the gullry unit is small.

[0005] In the case of a large gallery unit, the gallery unit is attached between upper and lower outer wall members, so that when the interlayer is displaced, the blades of the gallery unit may be twisted and deformed such as warpage. For example, if the upper frame of the unit frame is attached to the outer wall material attached to the upper floor, and the lower frame is attached to the outer wall attached to the lower floor, the upper frame and the lower frame will face each other due to the interlayer displacement of the outer wall material when interlayer displacement occurs. Moving in the opposite direction to the left and right, and the vertical frame becomes oblique, an excessively large force acts on the blade fixed to the left and right vertical frame with screws etc., and the blade twists,
Deformation such as warpage occurs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gully unit and a building outer wall provided with the gully unit which can solve the above-mentioned problems.

[0007]

According to a first aspect of the present invention, there is provided a mounting frame, a blade unit having a plurality of slats mounted on the blade unit frame, and a vertical portion of the blade unit frame is fixed to a vertical portion of the mounting frame. The upper horizontal portion of the blade unit frame is fixed to the upper horizontal portion of the mounting frame, and the lower horizontal portion of the blade unit frame can slide in the in-plane direction to the lower horizontal portion of the mounting frame so that the outer horizontal direction This is a gallery unit that is connected so as not to move.

According to a second aspect of the present invention, in the first aspect, the blade unit frame has a shape having a middle bone in an intermediate portion in the left-right direction, and an upper portion of the middle bone is fixed to an upper lateral portion of the mounting frame. This is a rattling unit in which the lower part of the middle bone is slidable in the in-plane direction on the lower side of the mounting frame so as not to move out of the plane.

According to a third aspect of the present invention, in the first or second aspect, the vertical portion of the mounting frame and the vertical portion of the blade unit frame are fixed so as to be relatively movable in an in-plane direction. .

According to a fourth aspect of the present invention, there is provided an outer wall of a building having a gallery unit in which a gallery unit is mounted between outer wall materials vertically adjacent to each other, wherein the gallery unit includes a plurality of slats on a mounting frame and a blade unit frame. The blade unit frame is fixed to the vertical portion of the mounting frame, and the upper horizontal portion of the blade unit frame is fixed to the upper horizontal portion of the mounting frame. The lower horizontal portion of the mounting frame is connected to the lower horizontal portion of the mounting frame so as to be slidable in the in-plane direction and not to move out of the surface, and the upper horizontal portion of the mounting frame is mounted on the upper outer wall material. , Wherein the lower lateral portion is attached to a lower outer wall material, which is a building outer wall provided with a rub-down unit.

[0011]

According to the first aspect, the upper horizontal portion of the mounting frame,
By moving the lower horizontal part in the opposite direction to the in-plane direction, the vertical part becomes diagonal, and the vertical part of the blade unit frame follows the vertical part of the mounting frame and becomes diagonal, but with the lower horizontal part of the blade unit frame The lower horizontal portion of the mounting frame slides relatively in the in-plane direction. As a result, the blade is twisted without exerting an excessively large force on the blade, and deformation such as warpage is reduced.

According to the second aspect, the strength of the blade unit frame in the out-of-plane direction is increased by the middle bone. The work of fixing the upper part of the middle bone to the upper side of the mounting frame and the work of fixing the lower part of the middle bone to the lower side of the mounting frame are easy.

According to the third aspect, when the vertical portion of the mounting frame is inclined, the blade unit frame moves in the plane with respect to the vertical portion of the blade unit frame. The angle is smaller than the vertical part. Therefore, deformation such as twisting and warping of the blade is further reduced.

According to the fourth aspect, when the upper outer wall material and the lower outer wall material are interlayer-displaced, the upper horizontal portion and the lower horizontal portion of the mounting frame move together with the upper and lower outer wall materials in opposite directions in the plane. The vertical part becomes oblique, and the vertical part of the blade unit frame follows the vertical part of the mounting frame and becomes diagonal, but the lower horizontal part of the blade unit frame and the lower horizontal part of the mounting frame are relative to the in-plane direction. Slide to. As a result, the blade is twisted without exerting an excessively large force on the blade, and deformation such as warpage is reduced.
