Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a heat insulating device for a parapet portion of a curtain wall.

PRIOR TECHNOLOGY Since the parapet section is constructed by attaching a cap that serves as a foothold between the top of the curtain wall and the top of the building frame, heat is conducted between the cap and the indoor side of the curtain wall. The heat received by the Kasagi is transmitted to the indoor side of the curtain wall, causing poor insulation.

For this reason, even if an insulating curtain wall is used, the insulation performance deteriorates due to the parapet part, and there are problems in that moisture between the curtain wall and the building frame is transmitted to the cap and condenses on the inside surface of the cap. .

Purpose of the invention It is possible to improve the insulation of the parapet by eliminating heat conduction between the cap and the indoor side of the curtain wall, and also to improve the insulation of the parapet part, and also to allow moisture between the curtain wall and the building frame to be transmitted to the cap and condense on the inside of the cap. The purpose is to ensure that there are no

Structure of the invention The top part of the curtain wall has a structure in which the indoor side member and the outdoor side member are connected through a connecting body made of a heat insulating material, and a moisture-proof sheet is attached between the indoor side member and the building frame. A heat insulating layer is formed between the indoor side material, waterproof sheet, and cap.

Embodiment Figure 1 is an overall schematic front view of a building using a curtain wall. On the outdoor side of the building frame, panel units A are continuously arranged vertically and horizontally to form a unit type curtain wall. ing.

The panel unit A has left and right vertical members (mullet).
An upper horizontal member 2 and a lower horizontal member 3 are constructed between 1 and 1 to form a frame, and a panel member 4 such as a window, glass, or heat insulation panel is attached within the frame.

Then, the upper horizontal member 2 of the uppermost panel unit A
A Kasagi 5 is attached to the parapet section.

FIG. 2 is a detailed cross-sectional view taken along the line - in FIG.
Primary fastener 1 fixed to the top of building frame B
0, a secondary fastener 11 is fixed with bolts and nuts 12 so as to be movable and adjustable in in-plane and out-of-plane directions, and a tertiary fastener 1 is attached to the secondary fastener 11.
3 is fixed by welding, and its tertiary fastener 13
A support 14 is fixed with bolts and nuts 15 in a vertically adjustable manner, and a downward hook 17 of a hook 16 fixed to the vertical member 1 is fitted to the support 14, so that the vertical member 1 is attached to the building frame. It is attached to B.

The upper horizontal member 2 has an indoor side member 20 and an outdoor side member 21 connected through a connecting body 22 made of a heat insulating material.
Upward and downward fitting grooves C and D are formed between the mounting frame 23 and the heat insulating body 2 in the upward fitting groove C.
4 and 24, and is connected to the indoor member 20 with screws 25, and the mounting frame 2
A drainer 23b is integrally formed on the upper wall 23a of 3, and this drainer 23b covers the upper part of the outdoor side member 21 and the vertical and horizontal covers 26, 27, and serves as a panel member in the downward fitting groove D. The insulation panel 4a and the glass 4b are packed indoors/outside 4
It is attached via c and 4d.

The cap 5 consists of first and second caps 30 and 40, and the first cap 30 has an upper horizontal member 31 and an indoor/outside vertical piece 3.
2 and 33 form a substantially downward U-shape, and the indoor/
The lower ends of the outer vertical pieces 32 and 33 are bent into hook shapes to form indoor/outside mounting pieces 34 and 35, and the outdoor mounting piece 35 is attached to an angle screwed to the upper wall 23a of the mounting frame 23. It is fixed to the material 36 with screws 37,
The outdoor vertical piece 33 is attached so as to be aligned with the vertical cover 26.

The second cap 40 includes an inclined upper horizontal piece 41 and an indoor vertical piece 42, and the outdoor side of the upper horizontal piece 41 is bent upward to become an outdoor mounting piece 43, and the lower end of the indoor vertical piece 42 is bent into a hook shape to form an indoor mounting piece 44, and the outdoor mounting piece 43 is located on the outdoor side of the indoor mounting piece 34 of the first cap 30, and is attached to the main body 2.
The indoor mounting piece 44 is fixed to a reinforcing frame 52 attached to the building frame B with screws 46.

On the other hand, the indoor attachment piece 34 of the first cap 30
is fixed to an attachment 53 fixed to the mounting bracket 51 with screws 38.

The reinforcing frame 52 is provided with inserts 58 and 58 in the building frame B.
A moisture-proof sheet 5 is attached via an L-shaped bracket 55 and an attachment plate 56 to a downward U-shaped attachment frame 54 attached via an attachment plate 59, and covers the attachment frame 54.
One end edge of 7 is connected to the indoor member 2 by the heat insulating material 50.
0, and the other edge is attached to a presser plate 60 on the vertical surface B ₁ on the indoor side of the building frame B than the primary fastener 10.
It is fixed with a fixing device 61, and blocks the air layer E between the indoor side member 20, the moisture-proof sheet 57, and the cap 5, and the air layer F between the indoor side of the panel unit A and the building frame B. This prevents the moisture in the air layer F from being transmitted to the cap 5 and condensing on the inner surface of the cap.

Moreover, the air layer E becomes a heat insulating layer, and the Kasagi 5
, indoor side member 20, fasteners 10, 11, 1
3. Improve the insulation of the parapet part by preventing heat from being conducted between it and the building frame B, so that the heat received by the Kasagi 5 is not transmitted to the indoor side member 20 (in other words, the indoor side) of the panel unit A. It is set as.

On the inner surfaces of the first and second caps 30 and 40,
A foamed heat insulating material 64 is injected and filled through filling holes 62 and 63 formed in the reinforcing frame 52 and the indoor attachment piece 44 of the second cap 40, thereby improving the above-mentioned heat insulating properties.

Effects of the idea: It is possible to improve the insulation of the parapet by eliminating heat conduction between the cap and the indoor side of the curtain wall, and the moisture between the curtain wall and the building frame is transmitted to the cap and condenses on the inside of the cap. This can be prevented.
