Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a window frame body with heat medium flow passages constituting a window frame such as a curtain wall having a temperature regulating function.

Prior art A temperature control function in which a window frame is formed by framing a window frame body with a heat medium flow path into a rectangular shape, and a heat medium such as hot water or cold water is circulated through the heat medium flow path of the window frame body. For window frames such as curtain walls, etc., various shapes can be considered for the window frame body, but considering the strength, heat transfer efficiency of thermal energy of the heat medium to the indoor side, extrusion moldability, etc., the shape shown in Figure 1 is considered. The shape shown in is preferable.

In other words, it is preferable to use a window frame body in which the indoor side wall b of the main body a is made thick, and the heat medium flow path c is formed in the indoor side wall b.

However, with this shape, the indoor wall b has to be thick and the weight becomes large, so as shown in FIG. Although the weight is reduced by forming d and d, this shape results in poor extrusion moldability.

In addition, since the vertical window frame body and the horizontal window frame body are connected and the heat medium flow paths between the two are connected, it is necessary to be able to easily maintain and inspect the connection part. If the window frame body has the shape shown in FIG. 2, inspection and maintenance work for the above-mentioned connecting portions becomes troublesome.

Purpose of the invention The purpose was to have strong strength, good heat conduction efficiency of the heat medium to the indoor side, good extrusion moldability, and also to enable easy maintenance and inspection of the connection part of the heat medium flow path. do.

Composition of the invention A hollow part and a heat medium flow path are formed in the indoor wall,
A cover body is attached to the side surface of the room, and a notch is formed at the end of the heat medium flow path forming part.

Embodiment Figure 3 is an overall schematic front view, and Figure 4 is a vertical cross-sectional view.The building frame has panel units A, which serve as window frames with a temperature control function, arranged continuously in the vertical and horizontal directions. It constitutes a formal curtain wall.

The panel unit A has a rectangular shape by constructing an upper frame 2, a horizontal window frame body 3, a waist frame body 4, and a lower frame 5 between the left and right vertical window frame bodies 1 and 1. A frame is formed, and a window 6, double glazing 7, and a heat insulating panel 8 are attached to the frame.
and panel members such as glass 9 are attached.

FIG. 5 is a detailed cross-sectional view taken along the line - in FIG.
The waistless member 4 has an indoor side member 10 and an outdoor side member 1.
1 are connected by bolts 13 with a spacing holder 12 made of a heat insulating material interposed therebetween, and a double glass 7, a heat insulating panel 8 and a glass 9 are installed between the indoor and outer members 10 and 11, respectively. .

The indoor side member 10 has an elongated hollow shape with a space 24 formed by upper and lower walls 20, 21 and indoor/outside walls 22, 23, the indoor side wall 22 is thick, and a hollow section 25 is formed in the upper part. is formed in the longitudinal direction to form a thin upper wall part B, both side connecting walls C, C, and a lower thick wall part D, and in the lower thick wall part D, a heat medium flow passage 26 is formed in the longitudinal direction. The indoor side surface 22a has a linear surface 22'a facing the hollow portion 25 and an arcuate surface 22''a facing the heat medium flow path 26.
The thermal energy of the heat medium flowing through the chamber 6 can be efficiently transmitted to the indoor side. In other words, it improves heat transfer efficiency.

An upper engaging portion 2 is provided on the upper indoor side of the indoor wall 22.
7 is formed, a vertical piece 28 is integrally formed on the lower surface 22b to constitute a recess 29, and a lower engaging part 30 is formed at the lower part of the vertical piece 28, and the upper and lower engaging parts 2
The upper and lower engaging pieces 3 of the cover body 31 span between 7 and 30.
2 and 33 are engaged, and the indoor side surface 2 of the indoor wall 22
2a and the recess 29 are covered.

Both ends of the indoor wall 22 are upper wall portions B.
and both side connecting parts C, C are cut out leaving some parts to form a cutout part 40, and the end face of the lower thick part D (that is, the heat medium flow path forming part) is cut out from the indoor side member 1.
0 (the end surfaces of the upper and lower walls 20 and 21 and the outdoor wall 23).

The waist mukume 4 and the mullion 1 are connected as shown in FIG.

That is, the end face of the indoor member 10 is brought into contact with the side surface 1a of the mullion 1 and connected with screws, etc., and a flexible rubber hose or the like is attached to the end of the heat medium flow path 26 to serve as the heat medium flow path connecting member. One end of the connecting cylinder 32 is threadedly connected via a connecting member 32a such as a unit nut, and the other end of the connecting cylinder 32 is connected to the connecting member 3 such as a unit nut from the side surface 1a of the mullion 1.
2b, the opening is connected to the heat medium flow passage 1' of the mullion 1, and the notch 40 is covered with a cover body 31.

Since the indoor side wall 22 of the indoor side member 10 is made thick, its strength is increased, and since the hollow part 25 and the recessed part 29 are formed, the weight is reduced, the extrusion moldability is improved, and the heat Thermal energy of the heat medium flowing through the medium flow path 26 can be efficiently transferred to the indoor side, and heat conduction efficiency can be improved.

In addition, the notch 40 allows a space E to be formed between the side surface 1a of the mullion 1 and the indoor side of the hipless mesh 4, and since the cover body 31 is detachably attached, the cover body 31 can be removed. As a result, the connecting cylinder 32 can be easily attached and detached, and the maintenance and inspection work of the heat medium flow passage connecting part can be easily performed, and the connecting cylinder 32 can be covered with the cover body 31, so that the appearance can be improved.

Although the above embodiments have been described with reference to the lower frame 4, the upper frame 2, the lower frame 3, the lower frame 5, and the mullion 1 may be constructed in the same manner, and the interior side member 10 alone may be used. It can also be used as a window frame.

Effects of the invention: Stronger strength, better thermal conductivity of the heating medium to the indoor side, better extrusion moldability, easier maintenance and inspection of the connecting parts of the heating medium flow path, and an improved appearance. It can be made into
