Description

[Detailed Description of the Invention] The present invention relates to a support structure for fireproof materials in a curtain wall.

For example, in the case of the spandrel part of a curtain wall, in order to maintain an appearance that harmonizes with the windows placed above and below it, the outer layer is made of glass, and the inner layer is made of fireproofing material for the building itself. Also, install fireproof and heat insulating materials in consideration of heat insulation. Among the above materials, the heat insulating material is made of glass wool and is relatively lightweight, whereas the fireproof material is made of cement-based materials, asbestos, gypsum, etc. and is heavy. A strong floor slab could be used to support heavy refractory material in place, i.e. at the back of the spandrels, but this is not possible due to the extremely low precision of the relative position of the floor slab to the curtain wall. cannot be relied upon.

Therefore, in a typical curtain wall constructed of mullions and horizontal frames between the mullions, the refractory material was usually supported by support brackets screwed to the horizontal frames. However, the horizontal frame is made of aluminum alloy profiles and is not strong enough to support heavy fireproof materials, and the width (height) on the indoor side is not very large, so the mounting position of the support bracket must be adjusted up or down. It was difficult to adjust.

The present invention was developed in consideration of the above-mentioned drawbacks of the conventional structure. Focusing on the vertically extending mullions of buildings, a C-shaped vertical groove is formed at the back of the mullion, and this groove is utilized. This provides a refractory support structure that can be adjusted vertically by attaching a strong support bracket.

The present invention will be described below with reference to Examples.

On both sides of the mullion 1, there is a glass fitting groove 3 formed by a ribbed edge 2, and in the fitting groove 3, a glass plate 6 is inserted between the mullions 1 arranged in parallel with a tight material 4 and a sealing material 5 interposed therebetween. Insert. On the indoor side of the glass plate 6, a panel-shaped refractory material 9 and a heat insulating material 10 are disposed between the upper horizontal frame 7 and the lower horizontal frame 8 to form a spandrel section S. W is a window section disposed above and below the spandrel section S (second window section).
figure).

In order to support the fireproof material 9, a vertical groove 11 having a C-shaped cross section extending in the longitudinal axis direction is formed on the indoor side, ie, the back side, of the mullion 1.

As shown in FIG. 3, the refractory material support bracket 13 that supports the refractory material has a channel portion 1 having a U-shaped cross section.
4 and the upper wing portions 15A, 15 of the channel portion 14.
It is formed of a rectangular plate-shaped receiving part 15 which is extended and fixed by means such as welding, and a hole 14A through which a bolt passes is bored in the web part of the channel part 14. It is preferable that the refractory support bracket 13 is made of a strong material such as iron. In order to secure the refractory support bracket 13 thus formed to the indoor side of the mullion 1 near the lower horizontal frame 8 using the bolt 16, the head 16A of the bolt 16 is fitted into the vertical groove 11. , hole 14A of refractory support bracket 13
A nut 17 is attached through the stem of the bolt 16, and after adjusting the vertical position of the refractory support bracket 13 and tightening it, the nut 17 is welded to prevent rotation. Furthermore, there is a stopper block 1 in the vertical groove 11.
8 is preferably welded and brought into contact with the lower surface of the bolt head 16A. In order to support the refractory material 9 on the refractory material support bracket 13 attached to the mullion 1 in this way, both lower ends of the refractory material 9, which are formed approximately equal to the distance between the mullions, are connected to two adjacent branches 15. They are respectively placed on wing portions 15A extending inward from the mullion.

Further, an auxiliary material 19 that also serves as a base for mounting the curtain box 22 is screwed to the back side of the horizontal frame 8, and a flat plate 21 is welded to the end of the auxiliary material 19, and the horizontal frame 8 is fixed in advance by an appropriate means. By welding the refractory material support bracket 13 attached to the side of the mullion 1 in the vertical position 1 and the flat plate 21, the mullion 1 and the horizontal frame 8 are kept in close contact with each other, and the space between them is maintained. Air and watertight performance can be improved.
It is advantageous to use the refractory material support bracket 13 in common, without providing a dedicated support bracket to support the heat insulating material 10, as the number of parts can be reduced. In that case, bend the back side of the auxiliary material 19 upward and insert it into the insulation material 1.
It is preferable to support the indoor side of 0. Sho 20
is the setting block.

The present invention is constructed as described above, and the refractory support bracket is attached using the vertical grooves of the mullions, so sufficient support strength can be obtained, and the vertical mounting position of the refractory support bracket can be freely adjusted. can do. Furthermore, the fireproof materials located on both sides of the mullion can be safely supported simultaneously.
