Abstract

The structure comprises a pillar member (1) including an indoor section (5) and arcuate outdoor section (6), a thermally insulating material (10) e.g. glass wool disposed in the space defined between the indoor and outdoor sections, a cylindrical, thermally insulating, spacer (7) e.g. of synthetic resin interposed between the indoor and outdoor sections (5, 6) passing through the material (10) and a screw (8) passing through the spacer (7) connecting the indoor and outdoor sections (5, 6) to each other. The indoor and outdoor sections (5, 6) form a panel holding groove (12, 12) at each end of each side of the same. <IMAGE>

Description

SPECIFICATION Corner structure of curtain wall This invention relates to a corner structure in an adiabatic curtain wall.
In a curtain wall, the heat insulation property of the'curtain wall has an important influence on the air conditioning efficiency in the curtain wall. Even if the panel portions in the curtain wall exhibit sufficient heat insulation functions, if the corner portions or the like, other than the panel portions in the curtain wall have an insufficient heat insulation capacity, the overall heat insulation capacity in the curtain wall is inevitably reduced to a substantial extent.
For example, U.K. Patent Nos. 2102112 and 2023277 disclose a corner construction of a curtain wall in which a metal skeleton column is used as a corner member. However, as the corner construction of these U.K. Patents does not include a heat insulation structure between the indoor portion and the outdoor portion, the overall heat insulation capacity of the curtain wall is greatly reduced.
In addition to the problem of the heat insulation, easy installation and good external appearance of the corner structure are essential in the curtain wall. U.K. Patents Nos. 2102112 and 2023277 do not refer to these points at all.
According to the present invention there is provided a corner structure of a curtain wall comprising a pillar member including an indoor section and an arcuate outdoor section, an adiabatic material disposed in the space defined between the indoor and outdoor sections, a cylindrical adiabatic spacer interposed between said indoor and outdoor sections through said adiabatic material, and a screw passed through said spacer and connecting between said indoor and outdoor sections to each other, said indoor and outdoor sections forming a panel holding groove at at least one end of each side of the same.
It is believed possible by means of the present invention is to provide a corner structure of the curtain wall which has a sufficient heat insulation capacity.
It is also believed possible by means of the present invention to provide a corner structure as aforementioned wherein the construction is easy for installation and the external appearance is pleasant.
In a preferred embodiment of the invention since the indoor and outdoor sections are separated from each other by the adiabatic material interposed therebetween, the room where the curtain wall is installed can be effectively cooled and heated without affecting the adiabatic system of the curtain wall. And since the indoor and outdoor sections of the pillar member can be easily and positively fastened together by the screw with the tubular of cylindrical spacer interposed between the indoor and outdoor sections, the sealing function of the panel members is not adversely affected.
Furthermore, even if rainwater invades the corner structure through the screw hole in the panel, since the tightened cylindrical spacer abuts and is sealed at the opposite ends against the indoor and outdoor sections, the rainwater will not invade the adiabatic material and thus, sufficient heat insulation can be maintained. Furthermore, since the outdoor section presents the arcuate outer surface and only few screws are employed to fasten the indoor and outdoor sections together, the curtain wall has a pleasant external appearance and is easy for construction.
The present invention will be described by way of examples with reference to the accompanying drawings in which: Fig. 1 is a perspective view of a corner structure embodying the present invention as seen from the outside of the room in which the corner structure is installed; Fig. 2 is a cross-section view taken along the line Il-Il of Fig. 1; and Fig. 3 is a cross-sectional view of a modified spacer.
Fig. 1 is a perspective view of a portion of a curtain wall in which the corner structure embodying the invention is incorporated as seen from the outside of a room where the curtain wall is installed. The curtain wall comprises curtain wall units each including two vertical members (in this case one of which is a pillar member 1 and the other is not shown) and a plurality of horizontal members 2 including upper, lower and intermediate horizontal members to provide a framework. The horizontal members 2 extend from the opposite faces of the pillar member 1 at substantially right angles to each other. In order to provide the curtain wall with a heat insulation feature, panels 3 such as a pair of glass sheets or adiabatic panels are fitted in the framework.
Fig. 2 shows the details of the pillar member 1 in cross-section taken along the line Il-Il of Fig.
1. The pillar member 1 includes a hollow indoor section 5 and an arcuate outdoor section 6 both of which can be formed by extruding aluminum, for example. These indoor and outdoor sections 5, 6 form the pillar member having a substantially sector-shaped cross-section as shown. In the illustrated embodiment, although the angle of the sector is shown as 90 , the angle of the sector may be varied if desired.
The panel members 3 are fitted and held in the grooves 12, 12 formed by opposing panel holders 13 and 14 at each end of each side of the indoor and outdoor sections 5 and 6, respectively. In Fig.
2, reference numeral 4 denotes a push member and reference numeral 11 denotes a gasket interposed between the associated panel member 3 and indoor and outdoor sections 5, 6.
The outer surface of the outdoor section 6 itself forms the outer surface of the pillar member 1 and is formed arcuated as stated above. The outdoor section 6 is formed at the central area in the width thereof with a holed screw receiving area 1 5 whereas the indoor section 5 is also formed with a holed screw receiving area 1 6 in the portion projecting outwardly from the rest of the indoor section in opposing the screw receiving area 1 5. Adiabatic (that is, thermal insulating) material 10 such as glass wool is disposed in the space 1 7 defined between the indoor and outdoor sections 5, 6. A spacer 7 in the form of a tube and preferably a cylinder is passed through the adiabatic material 10 and is provided between the indoor and outdoor sections 5, 6. The spacer is formed of material having sufficient rigidity, the ability to be firmly tightened and adiabatic (i.e.
thermal insulation) properties, such as synthetic resin. A screw 8 is threaded in through hole 9 formed in the spacer 7 and connects between the indoor and outdoor sections. Fig. 3 shows a modified embodiment of the spacer 7 which has seal material 1 8 of high sealing properties attached to the opposite ends thereof to provide a positive seal between the screw receiving areas 15,16.
The screw receiving area 1 5 of the outdoor section 6 is formed thicker than and continguous to the rest of the section 6 so that the screw receiving area is effectively prevented from deforming and/or being damaged when subject to stress which will be applied to the area when the screw 8 is tightened.
