Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to the structure of a building, and particularly to the structure of a partition panel attachment part in a mullion.

(Prior Art) Conventionally, a mullion section located inside the room has been used to attach a partition panel to the room.

An example of this is shown in FIG. 3, which shows a horizontal cross-sectional view of the mullion. The ends of a pair of mullion covers 2' and 2" bent around the mullion 1 located on the indoor side are overlapped and connected with screws 3'. Then, the other ends of the mullion covers 2', 2'' are screwed to the curtain wall 4'. A U-shaped partition panel mounting fitting 6' is fixed to the thus formed concave groove 5' on the indoor side via a base material (not shown), and a partition panel 7' is fitted thereto.

However, as can be seen from the figure, since the mullion covers 2' and 2'' are of an overlapping type, the manufacturing process is increased, and screw holes must be machined in order to attach the base material to the groove 5'. If the concave groove 5' is not used for attaching the partition panel, the screws used to attach the mullion covers 2', 2'' to the mullion 1' will be visible from the indoor side, spoiling the aesthetics.

(Purpose of the invention) The present invention was made in view of the above, and allows the use of a symmetrical mullioned cover, eliminates the need for a base material for mounting partition panel mounting brackets, and eliminates the need for screw heads that degrade the aesthetic appearance. To provide a structure of a partition panel mounting part in a mullion in which the partition panel is not visible from the indoor side.

(Structure of the invention) The above object is a structure consisting of a mullion attached to a building frame and erected, and a curtain wall section arranged on the outdoor side of the mullion, with a longitudinal wall attached to the indoor side of the mullion. An engagement receiving fitting fixed along the axis, and a symmetrical inverted L-shaped cross section that is attached between the engagement receiving fitting and the curtain wall portion and substantially covering both sides of the mullion and the interior side surface. A pair of mullion covers and a partition panel mounting bracket having a rectangular head bolt and having a U-shaped cross section, each of which has an indoor side end portion extending inward, and a partition panel mounting bracket having a rectangular head bolt and a partition panel mounting bracket having a U-shaped cross section. This is achieved by the structure of the partition panel mounting part in a mullion, which forms a C-shaped groove for accommodating the bolt head of the partition panel mounting fitting between the metal fittings.

(Example) As shown in FIG. 1, a mullion 2 is fixed to a floor slab 1 through a fastener 3 having mullions 2 erected in a notch of the floor slab 1. Further, a blind 5 is horizontally attached to the mullion 2 by an angle 4, and a curtain wall part 6 is disposed thereon. In the figure, 7 is the vertical frame of the curtain wall opening, which is connected to the mullion 2 by a small angle 8. Adjacent vertical frames 7 are connected to each other by battens 9. 10 is a tight material that seals the connecting portion of the vertical frame 7.

The mullion 2 is made of extruded steel or aluminum alloy, and since it protrudes into the interior space, it is necessary to decorate this part. First, an elongated engagement receiving fitting 11 having a substantially hat-shaped cross section is screwed onto the indoor side surface of the mullion 2 along the longitudinal axis. Engagement receiving grooves 12 are formed on both sides of the middle portion of the engagement receiving fitting 11 . Reference numeral 13 denotes a pair of mullion covers having a symmetrical inverted L-shape in cross section, which serve as decorative plates for mullion 2, and are made of aluminum alloy or the like. The folded portion 14A of the short side 14 of the mullion cover 13 is inserted into the engagement receiving groove 1.
2, and the outdoor end of the long side 15 is screwed to the vertical frame 7 of the curtain wall section. Therefore, both side surfaces of the mullion 2 and the interior side surfaces are almost entirely covered by the pair of mullion covers 13, 13.

The mullion cover 13 that covers the mullion 2 in this way,
Each of the short sides 14 of 13 is provided with a small extending portion 14B extending inward, and there is a space between the indoor end of the pair of mullion covers 13, 13 facing each other and the engagement receiving fitting 11. A C-shaped groove 16 is formed.

A partition panel mounting fitting 18 that supports the partition panel 17 is usually a long member having a U-shaped cross section, and is provided with a bolt 19 having a rectangular head. With the head of this bolt vertical, insert it into the C-shaped groove 16, rotate it approximately 90 degrees, tighten the nut onto the bolt 19, and attach the mounting bracket 18 to the mullion covers 13, 13.
Fixed to.

(Effects of the invention) The invention is constructed as described above, and since the pair of mullion covers have a symmetrical cross-sectional shape, it is easy to manufacture and manage during work, and there is no need for a base material for attaching the partition panel mounting brackets. Then, there is a C on the side of the room.
Since shaped grooves are formed, there are many advantages such as the ability to attach partition panels without drilling screw holes in the mullions.

Further, according to the embodiment of the present invention, since one end of the mullion cover is engaged and only the other end is fixed with screws, the installation work is extremely easy.
