Specifications

1.The composition of point-supported glass curtain wall
Point-supported glass curtain wall of glass panels supported by point fixing, usually four-point fixing, there are 6 or 8 point fixing. Steel point fixing bolts on the hole through the glass and glass link. Steel shaft and the point fixing bolt there is a gap between the hole and lined with nylon casing, supporting fixing between the Ministry of flexible gasket and glass, these measures have some leeway to make glass, but not in direct contact with metal, to prevent by force after the local stress excessive damage. Some of point fixing hinge can rotate the ball head, to better adapt to the glass surface by the plane after the bending load.

2.The point-supported glass curtain wall by the force characteristics
Acting on the point fixing the load on the wall and the role is:
Plane: vertical gravity loads; temperature effect; plane seismic effects;
Plane: the wind loads; horizontal seismic loads.
For point-supported glass curtain wall, since the control action is: the plane of gravity load, wind load for the plane.
The weight of the glass can withstand the fixing shaft, but also by a special spring suspension under gravity point to bear.
Wind and seismic forces of plane perpendicular to the wall of, by the fixing shaft bear.
Single-sided multi-point is support glass plate, under the action of the board itself by bending in the wind, and stress concentration at point fixing at the high level of stress greatly.
Glass at point fixing and stress point fixing structure, but also with processing the glass holes. Hole machining high precision grinding carefully, residual micro-defects (such as chipping, V-shaped notch, etc.) less, the stress concentration is low, stress is uniform; the other hand, a high degree of stress concentration, easily localized cracking. In addition, the bent edge of the warping board, board rotation, if the point fixing head can rotate with the rotation of the glass panel, the stress concentration can be greatly reduced.
Point-wall and in-plane and the plane are under the action of the load, the stress condition as shown. All bear the force, but the final pass through the supporting structure to the main structure up.
