Description

[Detailed Description of the Invention] The present invention relates to the improvement of mullion members in curtain walls, and is a proposal that eliminates the need for connection fittings when connecting upper and lower mullions.

Conventionally, the method of connecting mullions was to use a connecting fitting such as a joint sleeve or a joint pin at one end of the connecting part, but requiring a separate member for connection in this way requires additional manufacturing time and materials. There were various disadvantages, such as the high cost of the mullions required for the connection, and the hassle of attaching the connecting fittings to the mullions.

The purpose of this invention is to solve the above-mentioned drawbacks of the conventional method. Namely, the shape of the extruded aluminum material, which is a mullion, is made partially asymmetrical so that a part of the end part protrudes and is placed vertically opposite to each other. The protruding portion of the member is adapted to fit into the groove of the mating member.

To explain the present invention with reference to the embodiment shown in the drawings below, between a base body 1 with a rectangular cross section located on the indoor side and a flat exterior plate 2 located on the outdoor side, there is a gap between the center line of the base body 1 and the exterior plate 2. A slightly offset partition plate 3 is integrally formed, and the ends of the partition plate protrude from the upper surfaces of the ends of the base body and the exterior plate to form a projecting piece T, and the partition plate 3 is formed with the center line between them. Protrusions 5 and 5' are provided at the outer end of the base 1 opposite to 3 and the inner end of the exterior plate 2, with a gap 4 matching the wall thickness of the partition plate 3, so that the outer end of the base 1 Attachment recesses 7, 7' for the glass fixing frame 6 are formed on the end face and the inner end face of the exterior plate 2.

That is, in the present invention, the partition plate 3 is provided on one side of the center line connecting the base body 1 and the exterior plate 2, and on the opposite side of the center line, a gap 4 is provided and a protrusion 5 is formed. Therefore, when connecting mullions vertically, for example, when lowering the upper mullion member with the upper mullion member in the opposite direction, the protruding piece T of the partition plate 3 in the upper mullion member will fill the gap in the lower mullion member. 4, and the protruding piece T of the partition plate 3 of the lower mullion member also intervenes in the gap 4 of the upper mullion member, so the lower surface of the upper mullion is placed in contact with the upper surface of the lower mullion. If they are in close contact with each other, they will not separate.

As described above, in the present invention, the mullions to be connected face each other, and the partition plate protrusion T on one side is inserted into the gap 4 on the other side to naturally connect the mullions. Since there is no need for connecting fittings, there is a practical benefit in that manufacturing costs can be reduced and installation time can also be reduced.

It goes without saying that the mullion member of the present invention can be easily and quickly obtained by cutting an extruded aluminum material as in the conventional method.

[Brief explanation of drawings]

The drawings show one embodiment of the present invention, in which Fig. 1 is a plan view, Fig. 2 is a perspective view showing a state in which the upper and lower mullioned members are connected, and Fig. 3 is a front view of the same. 1 is a base body, 2 is an exterior plate, 3 is a partition plate, 4 is a gap, L is a center line, and 5 and 5' are protrusions.

Claims (1)

[Scope of utility model registration request] A diaphragm is formed between the base body and the exterior plate at a position where the center line connects the base body and the exterior plate to each other and on one side, and an end portion of the diaphragm protrudes from the upper surface of the end portion of the base body and the exterior plate to form a projecting piece, and the above-mentioned A cubic member for a curtain wall in which protrusions are provided opposite to each other at the outer end of the base body and the inner end of the exterior plate on the side opposite to the partition plate with a gap matching the wall thickness of the partition plate across the center line.
