POINT FIXED GLASS (SPIDER GLASS)

Point Fixed Glass is a curtain wall system that gives the building an architectural design and aesthetic appearance. The most important feature of this system is the maximum visibility between the interior and exterior environment due to the use of only transparent glass as the facade cladding material. 

Stainless or steel carrier pipes (profiles) are used in accordance with the intended use of the building and in line with the demands. Tempered or laminated glass is preferred in Spider glazing curtain wall, but tempered glass with a high level of safety, especially specially manufactured, is most preferred. 

Glass thicknesses are calculated according to the width and height of the area of use and static values are calculated and glass properties are selected. For water tightness, ultraviolet resistant silicone is used in athe horizontal and vertical joints between the glasses. The main carriers in the system are manufactured from normal steel or stainless steel in accordance with architectural requirements.

PRODUCTION AND QUALITY CONTROL

It has the capacity to produce with high precision with advanced technology in its production facility. Quality standards are applied in all production processes.

After the completion of the production processes, the products are checked with quality control procedures to ensure that they comply with the standards. And as the last stage, the packaging process is realized to be sent to our customers. 

SPIDER GLASS WITH STEEL CARRIERS

The steel tubes behind the glass surface provide a stylish and modern appearance thanks to the matt, glossy and painted surface of the carriers. 

The main carriers in the system are manufactured from normal steel or stainless steel in accordance with architectural requirements. 

Steel support beams vary greatly, with attention to detail and workmanship. Infrastructure can be constructed using tubular columns or complex trusses and other intricate steel substructures, often manufactured to the highest standards. This type of solution is suitable for vertical facades as well as for ceiling glazing applications.
Such systems are often combined with tension bar or cable systems providing a hybrid solution to minimize steel and increase transparency. Snow loads, negative wind pressures and slope requirements are critical design considerations. Rod or cable elements can be incorporated into the design according to the glass panel dimensions and lateral tensioning systems are often used to stabilize the façade structure.

STEEL TENSION ROD SPIDER GLAZING

Τension rod supporting solutions are used when dematerialization of the structureis needed, to provide a semi-transparent design with very high span. These systems vary widely in both design and configuration, allowing easily achieved vertical,overhead, vaulted and dome applications. Bow string trusses or suspended cable trusses rely on prestress forces into the tensile elements of the truss to provide stability. All materials are made of high quality stainless steel. Glass is processed accordingto safety requirements, usually being tempered or tempered laminated as well asheak soak tested. Depending upon conditions of span and load, the required prestress forces can be quite high, and must be resisted by adjacent building structure. 
 

CABLE POINT SUPPORTED SPIDER GLAZING

Cable net supporting solutions represent the ultimate elegant minimalistic structural glazing providing optimum façade transparency. Cable supported facades, often called cable nets, are used where large expanses of glass are required to enclose huge spaces, with limited intrusion from supporting structure. This structural system supports glass by pre-stressed cables in a net geometry, providing a very flat design.

The horizontal cables are tensioned against the adjacent building structures and the vertical ones between the roof structure and the ground. Cables are locked together with stainless steel clamps, which also hold the glass panes. 

STRUCTURAL GLASS FINS

Glass fins  represent the earliest form of structural glass façade and are used when the design intent is maximum achievable transparency. The result is a completely frameless and almost invisible facade, with no use of steel or concrete elements, providing complete air tightness and water proofing. Glass-fin glass walls are quite simple in concept, utilizing a glass fin set perpendicular to the glass pane at each vertical line of the glass grid. Glass panes (Single or Double Glazing Units) are attached to the fins with stainless steel fittings such as rotules, spiders, fin splices and clamps. The whole façade is suspended from concrete or steel beams via pin joints and is fixed to the floor using special stainless steel sill channels. 

SPIDER FIXED GLAZING TYPES

✓ The steel structure can use circular steel tube or bar, or fish belly type steel hinge supporting the structure or other structural hinge forms. The spider claws are installed between the steel structure and the glass panel with its four corners fixed. The fasteners of spider claws pass through the glass panel holes and clamping the glass panel after being fastened. This connection structure is flexible in material selection and simple in installation.

✓ Self-balancing Tension Cable Supported Point-fixing Curtain Wall:
It consists of pulling cable or draw rod and steel structure, with the prestressed force in pulling cable or draw rod keeping itself balanced and stable. It can take outside load action by decreasing the load transferred to the major structure. When designing, the prestressed force of the pulling cable or draw rod must be considered in advance. The pre-stressing of the tension must be pre- specified. The actual installation must be carried out in strict accordance with the prescribed standards.

✓ Single Cable Point-fixing Curtain Wall :
It is supported by concave soft cable networks, consists of large scale hanging cable and single layer wire crossing network point system. The large scale hanging cable network system forms different concave fold curtain wall by advanced form finding technology. This system has the super anti earthquake capability between the large scale cable and single layer wire network.

✓ Glass Rib Supported Point-fixing Curtain Wall
There is no steel structure in this system, the glass rib is used for supporting, and the spider claws are connected to the strong thick glass rib, the fasteners of spider claws pass through glass panel holes and clamping the glass panel after being fastened. The top of glass rib is fixed as hanging connection, and the base is as flexible connection.
