Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mullion-type curtain wall in which a panel is attached to a mullion member serving as a vertical member attached to a building frame, and a curtain wall in which a vertical member and a horizontal member are framed in a rectangular shape. This invention relates to a curtain wall such as a unit type curtain wall in which a curtain wall unit having a panel attached to the front side of the unit body is attached to a frame via its vertical members.

Conventionally, in the case of curtain walls in which panels are attached to vertical members attached to the frame, a continuous vertical gap may be formed between the frame and the panel, and in this case, air can flow through each floor. However, in the event of a fire, flames will propagate and smoke will penetrate between floors, so as shown in Publication No. 15858/1985, there is An interlayer plug made of fire-resistant material is fixed.

However, when the interlayer plug is fixedly installed between the slab and the spandrel in this manner, the slab and spandrel are integrally connected by the integrated interlayer plug, so that the slab and the spandrel cannot be displaced between the layers. For this reason, when an out-of-plane load acts on the curtain wall due to wind pressure, etc., unreasonable force is generated at the connection between the vertical members and the panels, and the connection between the frame and the vertical members, causing interlayer closure and each connection. may be damaged.

The present invention was made in view of the above circumstances, and its purpose is to be able to reliably maintain airtightness between each floor, to prevent flame propagation in the event of a fire and smoke from flowing between floors, and to reduce wind pressure, etc. To provide a curtain wall in which a connecting part between a vertical member and a panel and a connecting part between a frame and a vertical member are prevented from being damaged even when a load is applied in an out-of-plane direction.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal cross-sectional view of a unit type curtain wall, in which curtain wall units B are suspended from the top and bottom, left and right sides of a frame A to form a wall.

The curtain wall unit B has a panel B ₁ on the front side of a curtain wall unit body B 1 which is made up of a pair of left and right vertical members 1, 1, and an upper frame 2, a baseboard 3, and a lower frame 4, which are horizontal members, in a rectangular shape. ₂ is attached to the left and right curtain wall units.

As a result, the left and right vertical members 1, 1 of each curtain wall unit B are connected via the fasteners C, with one of them being fixed to the frame A and the other being connected to the frame A so as to be movable in the in-plane direction. Ru.

Mounting pieces 40 are welded and fixed to the lower end walls 5b of the shaped steel material 5 in a continuous manner with both end faces of the primary fasteners 14 in the in-plane direction. The indoor partition plate 41 extending between the end faces is fixed with screws 42, and the bent piece 32 of the brackets 30, 30' has a partition plate 41 extending between the inner walls 1a, 1a of the left and right vertical members 1, 1 of the curtain wall unit B. The outdoor partition plate 43 extending over the space is fixed with screws 44.

Indoor rising piece 43a of the outdoor partition plate 43
and a downwardly bent piece 41a of the indoor partition plate 41.
An indoor side dry packing 45 is installed between the outdoor side rising piece 43b of the outdoor side partition plate 43.
An outdoor dry packing 47 is installed between this and the heat insulating panel _B2 .

The upper end of the heat insulating panel B ₂ is connected to the upper frame 2 by screws 4 via a connecting body 48 made of a heat insulating material to the upper frame 2.
A packing 51 is provided between the presser foot edge 50 connected at 9,
51, and the lower end is connected to the lower frame 4 through a connecting body 52 made of a heat insulating material to the lower frame 4, and the screw 5
There is a packing 55 between the presser foot edge 54 connected at 3
55.

56 is a drainer provided between the lower frame 4, presser edge 54 and the upper frame 2, presser edge 50, and the ceiling 9 is attached to the upper frame 2 via an angle member 9a.

A stopper 59 is fixed to the interior wall 1b of the vertical member 1, and is fixed after the curtain wall unit B is attached to the fastener C. The amount of lift is regulated.

5 and 6 are longitudinal and cross-sectional views of a mullion-type curtain wall, and a horizontal piece 61a of a primary fastener 61 attached to the frame A via an anchor means 60 has a secondary fastener 62 attached thereto. The horizontal piece 62a is fixed with bolts and nuts 63, and a mullion bracket 64 is fixed to the vertical piece 62b of the secondary fastener 62 with bolts and nuts 65. The vertical member 66 is connected via a joint gasket 67 and a joint sleeve 68, and a presser piece 69 is integrally formed on the outdoor side of the vertical member 66, and between the presser piece 69 and the presser edge 70, The end of the panel 71 is packed 7

An indoor dry packing 76 is installed between the indoor side bent piece 74a of No. 4 and the outdoor side bent piece 72a of the indoor side partition plate 72. An outdoor dry packing 77 is attached between the piece 74b and the panel 71.

As described above, the present invention closes the gap between the frame and the panel with the indoor/outside partition plates and the indoor/outside dry packing, so it is possible to maintain airtightness between each floor, prevent flame propagation in the event of a fire, Smoke can be prevented from circulating between floors.

In addition, the amount of displacement of the panel when an out-of-plane load is applied due to wind pressure, etc. is absorbed by the outdoor dry packing, and when a large out-of-plane load (impact force) that displaces the vertical members is applied, Since the amount of displacement is absorbed by dry packing on both the indoor and outdoor sides, it is possible to prevent damage to the connecting parts between the panels and the vertical members, and between the vertical members and the frame.

Furthermore, since the interior and exterior packing is dry packing, work can be done even in rainy weather, and the installation work is easy.

Note that durability can be ensured by using noncombustible materials for the indoor and outdoor dry packing.

In addition, the indoor partition plate and the outdoor partition plate are in contact with each other through the indoor dry packing, and the outdoor partition plate and the panel are in contact with each other through the outdoor dry packing, so they can be relatively displaced. , flexibility in thermal expansion.

Furthermore, since the partition plates are connected to each other through dry packing, even if the panels or vertical members are displaced, the squeaks that occur when metals come into contact with each other will not occur.
