Description
SPECIFICATION
Connecting structure forframable sections in prefabricated unit type curtain wall assembly
This invention relates to a prefabricated unit type curtain wall assembly, and more particularly to a connecting structure for framable sections having heat transfer medium circulation passages for providing the curtain wall assembly with a built-in room temperature control system or air conditioning system.
In a prefabricated unit type curtain wall assembly wherein a pluraity of framable sections constituting the framework for the curtain wall assembly are formed with heat transfer medium circulation passages through which hot water, cold water or air is allowed to circulate to regulate the temperature of a room, it is also necessary to interconnect such heat transfer medium circulation passages when the framable sections are interconnected, and the framable sections are of a special construction.
Figure 1 of the accompanying drawings is a fragmentary sectional view of a connecting structure forframable sections in a prefabricated unit type curtain wall assembly of the prior art, namely, British
Patent Specification No. 2 023 277.
Stated briefly, in the connecting structure as shown in Figure 1, end face b' of a first section b having a heat transfer medium circulation passage a is allowed to abut against one side wall d' of a second section d having a heat transfer medium circulation passage c, said one side wall d' of the second section dhaving an opening eformed therein which opens into the heat transfer medium circulation passage a of the first section b; a connecting memberh having a passage fand a threaded hole g formed therein is fitted in between the heat transfer medium circulation passage a of the first section b and the opening e; and a bolt! its threadably engaged through the other side wall d" of the second section d" into a threaded hole g so as to interconnect the first and second sections and d and also interconnect the heat transfer medium circulation passages a and c.
This connecting means is, however, disadvantageous in that it is sometimes impossible to accurately connect the first and second sections b and ddue to working or machining errors of the sections b,d, the connecting member h and the opening e, resulting in leakage of the heat transfer
medium from the connection of the heat transfer
medium circulation passages a and c, and therefore, machining and connecting of the component parts
and troublesome and time-consuming.
Moreover, the framable sections expand and
contract by heat because hot water/cold water flow through the heat transfer medium circulation passages. However, since the first and second framable sections are connected directly so as not to allow them to make a relative displacement, the thermal expansion and contraction of the sections tend to cause bending of them and fracture of the connections thereof which result in leakage of the heat transfer medium.
It is believed possible by means of the present invention to provide a connecting structure for sections wherein a pair of framable sections having heat transfer medium circulation passages formed therein can be interconnected without causing any leakage of heat transfer medium through the connections of said passages even in cases where they have machining errors.
Another believed possibility of the present invention is to provide a connecting structure for sections wherein a pair of framable sections having heat transfer medium circulation passages formed therein can be interconnected without causing any leakage of heat transfer medium even when they expand and contract thermally.
Further believed possibility of the present invention is to provide a connecting structure for sections wherein a pair of framable sections of a simple construction having heat transfer medium circulation passages can be connected readily.
According to the present invention, there is provided a connecting structure for framable sections in a prefabricated unit type curtain wall assembly, comprising a pair of framble sections each having a heat transfer medium circulation passage and their repective opposed ends being cut at a predetermined angle so as to be interconnected, the ends of respective heat transfer medium circulation passages of the pair of framable sections being cut so as to lie short of the opposed end faces of said framable sections; a pair of connector members adapted to be connected to the open ends of said heat transfer medium circulation passages, respectively; and a member having a heat transfer medium communication passage formed therein adapted to connect said pair of connector members.
Preferably said pair of connecting members are pipe joints adapted to be threadably engaged with the open ends of said heat transfer medium circulation passages.
Preferably the member having said heat transfer medium communicating passage formed therein is made of a flexible material and is connected and fixedly secured to the pipe joint by means of a nut threadably engaged with the pipe joint.
Preferably said connector members each comprises a pipe joint whose base end is adapted to be threadably engaged with the open end of the heat transfer medium circulation passage and which has a stepped portion formed in the outer peripheral surface of the leading end thereof and has also a circumferentially extending groove formed in the peripheral surface of the approximately intermediate portion thereof in the longitudinal direction; a flexible pipe having a large diameter stepped bore formed in the leading end thereof and in which said stepped portion of the pipe joint is fitted; and a connector piece whose one end is fitted to the shoulder of the portion of said flexible pipe having large diameter stepped bore formed therein so as to be turnable freely and whose the other end is engaged with the groove of said pipe joint.

The member 20 located on the side of the room comprises a hollow frame portion 23 located on the side of the room and a hollow frame portion 24 located outside the frame portion 23. The hollow frame portion 23 is of an approximately rectangular, hollow frame configuration formed by left and right inside walls 23a and 23b crossing at right angles, and left and right outside walls 23e and 23dwhich cross at right angles.The hollow frame portion 24 located outside the hollow frame portion 23 has left and right outer side walls 24a and 24b to which the left and right side walls 21a and 21b of the member 21 are connected, respectively through the heat insulating connectors 22. Reference numeral 25 denotes a batten, 26 a vertically extending cover, and 27 a transversely extending cover.
Each of the 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 A1 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 unitA1 by means of 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 unitA2 by means of the inner and outer packing bandss 38 and 39.
Further, the outer packing band 39 comprises first and second outer packing bands 39, and 392 abutted each other.
As shown in Figure 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, and inside wall 40e and an outside wall 40d. Fixedly secured to the lower part of the framable section 40 is an upwardiy open
U-shaped frame member 44. The inside wall 40e has a heat transfer medium circulation passage 45 formed therein. Reference numberal 46 denotes a cover, and 47 a member for regulating the amount of air to be blown off.
As shown in Figure 5, the opposite end faces C and
D of framable/formable section members 40,40 of the transoms 10 and 11 are cut at an angle of 45 degrees, and the end faces E and Directed towards outside walls 40d are cut at right angles to each other. Each of the inside walls 40e is cut off by a predetermined length, and the end faces G and H adapted to abut against each inside wall 40e are located inside the aforementioned opposite end faces Cand D, respectively.
Thus, the framable/formable sections 40 and 40 of the left and right transoms 10 and 11 can be connected as mentioned hereinbelow.
Stating in brief, the end faces E and Fformed 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" arse spaced apartwith a predetermined clearancetherebetween 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, 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 is fixedly secured thereto. Further, a connection plate 54 extends along the inner connector member 51 and is fixedly secured thereto.
A pair of connector members 60 are threadably engaged with and fixedly secured to one end of each of the members having heat transfer medium circulation passages 45 formed therein. A member 70 made of a flexible material such as rubber or a flexible synthetic resin which serves as a heat transfer medium communication passage is connected between the connector members 60,60 of the left and right transoms 10 and 11 so as to allowthe 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 Figure 5, threaded end portions 61 a of pipe joints 61 are threadably engaged with the respective ends of the heat transfer medium circulation 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 "0" rings. A union nut 63 is threadably engaged with the other threaded end 61e of each of the pipe joints 61, while each end of the rubber hose 70 which serves as heat transfer medium communication passage is thrusted against and fixedly secured to the other engaging end portion 61 d of each of the pipe joints 61.
Thus, as shown in Figures 3 to 6, the pair of framable sections 40, 40 each having the heat transfer medium circulation passage 45 can be connected to the left and right inside 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 40e 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 Cand D, respectively, oftheframable sections 40,40 a space required for connecting the pipe joints 61,61 and the rubber hose 70 can be secured, and also the oposed 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 contraction 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.
Further, 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 connected at any desired angle.
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 60 and heat transfer medium communication passage 70 as shown in Figures 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 formed 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 larger 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.
