Spider curtain wall.
- With constant development in science and technology, glass curtain walls are finding increasingly more applications and their structures are also experiencing great changes. Fully spider fitting frameless glass curtain walls, connect glass together in an open space using various types of light/heavy steel structures via various types of spider fitting members to form flexible and unobstructed glass façade. In this way, fully spider fitted glass walls not only maintain the safety of aluminium alloy frame glass curtain wall but also eliminate the disadvantages of the later in singular structure and restrictions from construction structures. As a result they provide unobstructed view as a whole, neat, bright and integrated with such advantages as safety, practicality and artistic taste thus becoming a vogue for modern construction and decorations.
- – Thermally toughened or tempered glass panels are used as single or insulated glass units. In case of single panels laminated safety glass is preferred due to safety reasons. This system consists of a number of accessories with metal arms. At the end of each arm, a sheet of glass is fixed by the corners with a special screw. The vacuum between these sheets is filled up with isolators to overcome mechanical pressure and weather conditions.
- The rectangular glass sheets have 4 or 6 countersunk drilled holes into which countersunk stainless steel bolts acting as point-fixings. The space between the glass panes are filled with weather seal. The support elements that hold the fitting can be space frame, glass fin, tension cables or steel circular columns to provide the aesthetic effect as desired by the customer.
Application Of Spider Systems
- Large main entrance facades of buildings and shop front facades.
- Glass canopies.
- Skylights and domes.
- Frameless glass curtain wall
- Structural Curtain wall.
Unitized curtain wall
Stick curtain wall
This is an outer covering placed on a building. This has a great advantage, as glass (which is mostly used) can allow more natural light into the building. The curtain wall is fixed to the wall of the building and does not carry any other weight aside its own.it is designed to resist air and water infiltration, sway induced by wind and other seismic forces acting on the building, while increasing its aesthetic features.
Depending on the type of glass used, it can also increase heat insulation (by deflecting sun rays) and sound insulation (if glass is laminated).
Types of curtain wall (according to design and mode of installation):
- Structural curtain walls; these are basically framed curtain walls with veins along the glass panels
- Frameless curtain walls; these have concealed frames with no veins along the glass panels.
- Unitized curtain walls; these can be structural or frameless but are designed as separate panels which can be installed independent of themselves.
- Spider curtain walls; these are curtain wall without frames, they have poles and spider fin for structural support.
