Reference numeral 25 denotes a batten, 26 a vertically iZ1~8 extending cover, and 27 a transversely extending cover.
Each of th~ mullions 2 and 3 comprises a main body 30 and a batten 31 interconnected by means of a bolt 33 through a heat insulating connector 32. The main body 30 is formed, on the side of the room, with a heat transfer medium flow passage 34 and a transverse recess 35, and has also a hollow intermediate portion forming an air flow passage 36 as well as a first transverse recess or groove 37 formed in the outside thereof. The above-mentioned batten 31 has a second transverse recess or groove 372 formed therein. Mullions 2' and 3' of panel units Al and A2 are of the same shape as those of the mullions 2 and 3. The mullion 2 is connected to the mullion 2' of the panel unit Al by means o packing bands 38 and 39 located inside and outside relative to the room, whilst the mullion 3 is connected to the mullion 3' of the panel unit A2 ~y means of the inner and outer packing bands 38 and 39.
Further, the outer packing hand 39 comprises first and second outer packing bands 391 and 392 abutted each other.
As shown in Fig.4, the aforementioned transoms 10 and 11 are identical in configuration wherein a framable section 40 is connected by means of a bolt 43 through a heat insulating connector 42 to a batten 41. Each of the framable sections 40 is a long member having a hollow space 40' defined by an upper wall 40a, a lower wall 40b, an inside wall 40c and an outside wall 40d. Fixedly secured to the lower part of the framable section 40 is an upwardly open U-shaped frame member 44. The inside wall 40c has a heat transfer medium l'~l9~Z8 circulation passage 45 formed therein. Reference numeral 46 denotes a cover, and 47 a member for regulating the amount of air to be blown offO
As shown in Fig.5, the opposite end faces C and D
of formable section members 40, 40 of the transoms 10 and ll are cut at an angle of 45 deyrees, and the end faces E and F
directed towards outside walls 40d are cut at right angles to each other. Each of the inside walls 40c is cut off by a predetermined length, and the end faces G and H adapted to abut against each inside wall 40c are located inside the aforementioned opposite end faces C and D, respectively.
Thus, the formable sections 40 and 40 of the left and right transoms lO and ll can be connected as mentioned hereinbelow.
Stating in brief, the end faces E and F formed to cross at right angles are brought into contact with the left and right inside walls 23a and 23b, respectively, of the corner mullion 1 and then fastened thereto by means of screws 48. Then, the opposite end faces C and D cut at an angle of 45 are spaced apart with a predetermined clearance there-between in which a caulking member 49 is fitted. An L-shaped outer connector member 50 is fixedly secured at both ends thereof to the inner surfaces of the outside walls 40d, 40d and the lower walls 40b, 40b. Whilst, L-shaped brackets 52, 52 are fixedly secured by means of screws to mounting portions 50a, 50a, respectively, of an outer connector member 50. A
connection plate 53 extends between the brackets 52, 52 and g lZ19~28 is fixedly secured thereto. Further, a connection plate 54 extends along the inner connector member 51 and is fixedly secured thereto.
A connector member 60 is threadahly engaged with and fixedly secured to one end of each of the members having heat transfer medium circulation passages 45 formed therein.
A member made of a flexible r.late.rial such as rubber or a flexible synthetic resin which se~ves as a heat transfer mediurn communication passage 70 is connected between the connector members 60, 60 of the left and right transoms 10 and 11 so as to allow the heat transfer medium circulation passages 45, 45 of the left and right sections 40, 40 to communicate with each other.
Stating in more detail, as shown in Fig.5, threaded end portions 61a of pipe joints 61 are threadably engaged with the respective ends of the heat trans~er mediurn circula-tion passages 45, 45 so that the respective flanges 61b of the pipe joints 61 may be thrusted against end faces G and H, respectively through "O" rings. A union nut 63 is thr~adably engaged with the other threaded end 61c of each of the pipe joints 61, while each end of the rubber hose 70 which serves as heat transfer mediurn communication passage is thrusted against and fixedly secured to the other engaging end portion 61d of each of the pipe joints 61.
Thus, as shown in Figs. 3 to 6, the pair of framable sections 40, 40 each having the heat transfer medium circula-tion passage 45 can be connected to the left and right inside 1;~19 ~ZB
walls 23a and 23b of the corner mullion 1 by means of the inner and outer connector members 51 and 52 etc.
Further, since the inside walls 40c which form the heat transfer medium circulation passages 45 are cut so as to allow the end faces G and H lie short of -the end faces C
and D, respectively, of the framable sections 40, 40, a space required for connecting the pipe joints 61, 61 and the rubber hose 70 can be secured, and aLso the opposed heat transfer medium circulation passages 45, 45 can be connected by means of the pair of pipe joints 61, 61 and the rubber hose 70.
Therefore, even if the framable sections 40 have working errors, they can be compensated or absorbed by the elastic deformation of the rubber hose 70 thereby preventing the possible leakage of the heat transfer medium from the connection between the opposed heat transfer medium circulation passages 45, 45.
Further, the elastic deformation of the rubber hose 70 accommodates or absorbs the possible expansion and con-traction of the framable sections 40, 40 thereby preventing the leakage of the heat transfer medium through the connection.
Moreover, since the pair of framable sections 40, 40 are connected by the inside and outside connector members 51 and 50 etc., and the opposed heat transfer medium circulation passages 45, 45 are connected by the pair of pipe joints 61, 61 and the rubber hose 70, the construction of the connecting part can be simplified, and also connecting operation can be made readily and simply.
1~ L9 ~28 Fuxther, since the rubber hose 70 can be deformed elastically in accordance with the angle of connection between the pair of framably sections 40, 40, the latter can be con-nected at any desired angle.
S In the aforementioned embodiment, there is described the connection of the framable sections forming the transoms, the present invention is not to be limited to it, but is also applicable to connections of all framable sections having heat transfer medium circulation passages which form a curtain wall assembly.
Further, a variant of connector member ~0 and heat transfer medium communication passage 70 as shown in Figs. 7 and 8 can also be used wherein the pipe joint 61 has a stepped portion 64 formed at the other end thereof; the flange 61b has an engaging groove 65 formed therein; the flexible pipe 70 has a large stepped bore 71 ~ormed at the end thereof and in which the stepped portion 64 is fitted; a pair of connector pieces 72 made of spring plate are attached to the shoulder -on the large diameter portion of the pipe 70 so as to be turned freely and an engaging portion 72a of the pin 70 is detachably engaged with the groove 65~
It is to be understood tha-t the foregoing description is merely illustrative of the preferred embodiments of the invention, and that the invention is no-t to be limited thereto, but is to be determined by the scope of the appended claims.

The mullion 2 is connected to the mullion 2' of the panel unit Al by means o packing bands 38 and 39 located inside and outside relative to the room, whilst the mullion 3 is connected to the mullion 3' of the panel unit A2 ~y means of the inner and outer packing bands 38 and 39.
Further, the outer packing hand 39 comprises first and second outer packing bands 391 and 392 abutted each other.
As shown in Fig.4, the aforementioned transoms 10 and 11 are identical in configuration wherein a framable section 40 is connected by means of a bolt 43 through a heat insulating connector 42 to a batten 41. Each of the framable sections 40 is a long member having a hollow space 40' defined by an upper wall 40a, a lower wall 40b, an inside wall 40c and an outside wall 40d. Fixedly secured to the lower part of the framable section 40 is an upwardly open U-shaped frame member 44. The inside wall 40c has a heat transfer medium l'~l9~Z8 circulation passage 45 formed therein. Reference numeral 46 denotes a cover, and 47 a member for regulating the amount of air to be blown offO
As shown in Fig.5, the opposite end faces C and D
of formable section members 40, 40 of the transoms 10 and ll are cut at an angle of 45 deyrees, and the end faces E and F
directed towards outside walls 40d are cut at right angles to each other. Each of the inside walls 40c is cut off by a predetermined length, and the end faces G and H adapted to abut against each inside wall 40c are located inside the aforementioned opposite end faces C and D, respectively.
Thus, the formable sections 40 and 40 of the left and right transoms lO and ll can be connected as mentioned hereinbelow.
Stating in brief, the end faces E and F formed to cross at right angles are brought into contact with the left and right inside walls 23a and 23b, respectively, of the corner mullion 1 and then fastened thereto by means of screws 48. Then, the opposite end faces C and D cut at an angle of 45 are spaced apart with a predetermined clearance there-between in which a caulking member 49 is fitted. An L-shaped outer connector member 50 is fixedly secured at both ends thereof to the inner surfaces of the outside walls 40d, 40d and the lower walls 40b, 40b. Whilst, L-shaped brackets 52, 52 are fixedly secured by means of screws to mounting portions 50a, 50a, respectively, of an outer connector member 50. A
connection plate 53 extends between the brackets 52, 52 and g lZ19~28 is fixedly secured thereto. Further, a connection plate 54 extends along the inner connector member 51 and is fixedly secured thereto.
A connector member 60 is threadahly engaged with and fixedly secured to one end of each of the members having heat transfer medium circulation passages 45 formed therein.
A member made of a flexible r.late.rial such as rubber or a flexible synthetic resin which se~ves as a heat transfer mediurn communication passage 70 is connected between the connector members 60, 60 of the left and right transoms 10 and 11 so as to allow the heat transfer medium circulation passages 45, 45 of the left and right sections 40, 40 to communicate with each other.
Stating in more detail, as shown in Fig.5, threaded end portions 61a of pipe joints 61 are threadably engaged with the respective ends of the heat trans~er mediurn circula-tion passages 45, 45 so that the respective flanges 61b of the pipe joints 61 may be thrusted against end faces G and H, respectively through "O" rings. A union nut 63 is thr~adably engaged with the other threaded end 61c of each of the pipe joints 61, while each end of the rubber hose 70 which serves as heat transfer mediurn communication passage is thrusted against and fixedly secured to the other engaging end portion 61d of each of the pipe joints 61.
Thus, as shown in Figs. 3 to 6, the pair of framable sections 40, 40 each having the heat transfer medium circula-tion passage 45 can be connected to the left and right inside 1;~19 ~ZB
walls 23a and 23b of the corner mullion 1 by means of the inner and outer connector members 51 and 52 etc.
Further, since the inside walls 40c which form the heat transfer medium circulation passages 45 are cut so as to allow the end faces G and H lie short of -the end faces C
and D, respectively, of the framable sections 40, 40, a space required for connecting the pipe joints 61, 61 and the rubber hose 70 can be secured, and aLso the opposed heat transfer medium circulation passages 45, 45 can be connected by means of the pair of pipe joints 61, 61 and the rubber hose 70.
Therefore, even if the framable sections 40 have working errors, they can be compensated or absorbed by the elastic deformation of the rubber hose 70 thereby preventing the possible leakage of the heat transfer medium from the connection between the opposed heat transfer medium circulation passages 45, 45.
Further, the elastic deformation of the rubber hose 70 accommodates or absorbs the possible expansion and con-traction of the framable sections 40, 40 thereby preventing the leakage of the heat transfer medium through the connection.
Moreover, since the pair of framable sections 40, 40 are connected by the inside and outside connector members 51 and 50 etc., and the opposed heat transfer medium circulation passages 45, 45 are connected by the pair of pipe joints 61, 61 and the rubber hose 70, the construction of the connecting part can be simplified, and also connecting operation can be made readily and simply.
1~ L9 ~28 Fuxther, since the rubber hose 70 can be deformed elastically in accordance with the angle of connection between the pair of framably sections 40, 40, the latter can be con-nected at any desired angle.
S In the aforementioned embodiment, there is described the connection of the framable sections forming the transoms, the present invention is not to be limited to it, but is also applicable to connections of all framable sections having heat transfer medium circulation passages which form a curtain wall assembly.
Further, a variant of connector member ~0 and heat transfer medium communication passage 70 as shown in Figs. 7 and 8 can also be used wherein the pipe joint 61 has a stepped portion 64 formed at the other end thereof; the flange 61b has an engaging groove 65 formed therein; the flexible pipe 70 has a large stepped bore 71 ~ormed at the end thereof and in which the stepped portion 64 is fitted; a pair of connector pieces 72 made of spring plate are attached to the shoulder -on the large diameter portion of the pipe 70 so as to be turned freely and an engaging portion 72a of the pin 70 is detachably engaged with the groove 65~
It is to be understood tha-t the foregoing description is merely illustrative of the preferred embodiments of the invention, and that the invention is no-t to be limited thereto, but is to be determined by the scope of the appended claims.
