Fully-Unitised System

Description: The wall is composed entirely of large framed units pre-assembled in the factory, complete with spandrel panels (if any) and often pre-glazed in the factory as well. The vertical edges of the unitised panels join to form mullion members; top and bottom members join to form horizontal transoms.

Advantages and Limitations: Unitised panels are fully assembled under controlled factory conditions. Installation speed is fast and that facilitates rapid closure of the building envelope. Relatively less dependent on field adjustments to achieve established quality standards and less field workers are required. Pressure-equalised design principle can be applied in the Curtainwall design. Minor disadvantages include relatively high construction cost and elaborate protective measures for the unitised panels are needed.

Open-Joint Aluminium Cladding System

Description: A non-load bearing external cladding assembly defined as a wall comprising an outer skin of panels and an airtight insulated/non-insulated backing wall separated by a ventilated cavity. It is designed in such a way that the air gap between the cladding system and the building's inner leaf should have either a proper drainage and ventilation system or is pressure equalized (the air pressure in the gap is the same as that of the outside conditions). This ensures that the cladding system provides enough "pressure cushion" as a protective layer.

Advantages of this System:
  1. Superb formability
  2. Wide range of fixing and jointing techniques
  3. Light-weight and easy to handle in the workshop and on site
  4. Low maintenance
  5. Low deadweight as compared to stone finishes
  6. Easy to install

Semi-Unitised System

Description: As the term implies, this is a compromise between the Stick System and the Fully-Unitised system. In this system, the mullions are separately installed prior to the assembly of the pre-assembled framed panels which are placed between the mullions. These panels may be full storey in height or may be divided into a spandrel unit and a vision glass unit. This system allows for factory glazing of the glass panels. This improves the quality of the sealing system.

Advantages and Limitations: The advantages and limitations of this system are comparable to the Unitised System. Pressure-equalized design principle is also not possible for this system.

Stick Systems

Description: The Stick System was used extensively in the 50's and 60's which represented the early years of Curtain Wall Development. This system must be installed in segments (mullions, transoms, etc.). Water-tightness design is done with the use of sealing systems such as sealants or gaskets.

Advantages and Limitations: The advantages are relatively lower material costs, shipping and handling costs and a simplistic system design. The disadvantages of a stick system are the necessity of field assembly work, rather than controlled factory conditions, and the fact that pre-glazing is unachievable. In comparison with the Fully/Semi-unitised System, movement and expansion tolerances are limited.

Point Supported Glass Façade System

It has been increasingly popular to attach the glass to the structure using fittings directly connected through holes in the glass. These fittings allow improved transparency and offer additional architectural opportunities in the detailing of these connections. Architects nowadays design structures with reduced or eliminated visual barriers between the outside and inside of buildings. This trend means that modern buildings today have fewer impediments to the outside view. The application of this Façade System allows for the realization of such structural designs.
Aluminium Mullion System

The 1970's began the widespread use of aluminium extrusions for mullions. Aluminium offers a unique advantage as it can be easily extruded into nearly any shape required for design and aesthetic purposes. Today, the design complexity and shapes available are nearly limitless. Custom shapes can be designed and manufactured with relative ease.

Limitation: The modulus of elasticity of aluminium is about 1/3 that of steel. This translates to 3 times more deflection in aluminium mullions compared to stainless steel mullions.

Glass Mullion System

Aluminium/Steel Mullions can also be in-filled/replaced by glass, which provide an architecturally pleasing building as well as being able to maximize on the benefits of day lighting. The resulting structure virtually disappears from view. This is achieved by eliminating all notions of structural support and devising a composite system in which the glass operates as a component of a working structure. However, parameters related to solar gain control such as thermal comfort and visual comfort are more difficult to control especially when using high-glazed curtain walls.

Stainless Steel and Steel Mullion System

Deflection in mullions is controlled by different shapes and depth of curtain wall members. The depth of a curtain wall system is usually controlled by the area moment of inertia required to keep deflection limits within the specification. The area moment of inertia refers to the property of a shape that is used to predict its resistance to bending and deflection. Another way to limit deflection in a given section is to choose steel (which has a higher modulus of elasticity) instead of aluminium. The steel can resist much of the load at a lower cost or smaller depth.

Tensile Fabric/Tensile Structure

A tensile structure is a construction of elements carrying only tension although, for the most part, they are supported by some form of compression or bending components such as masts, compression rings or beams. Tensile membrane structures are most often used as roofs as they can economically and attractively span large distances. They have long been used in tents, where the guy ropes provide pre-tension to the fabric and allow it to withstand loads.

Steady technological progress has increased the popularity of tensile roof structures. The low weight of the materials makes construction easier and cheaper than standard designs, especially when vast open spaces have to be covered.

The final shape or form of a fabric structure depends on the:
  1. shape or pattern of the fabric
  2. geometry of the supporting structure (such as masts, cables, ringbeams, etc.)
  3. pre-tension applied to the fabric or its supporting structure.

Tension Rod Systems

This system forms part of a Tensile Structure. This form of construction has become well understood and widespread in large structures in the latter part of the twentieth century.

Tension Structures can span any number of panels over any distance. However, the larger the span, the larger the rods required and the greater the tension forces required to maintain stability and resist the applied loading. It is, therefore, important to ensure that the host structure will be strong enough to withstand the forces imposed on it by the Tension Structure.

Glass Roof System

Glass Roof Systems capture timeless architectural traditions that have been popular for centuries. Exterior roof finishes also include aluminium in standard or custom colors. Glass Roof Systems provide a light and airy space but installation and maintenance of this system require special consideration to minimize the risk of serious injury or death. During installation, cleaning and maintenance, work should be performed from secured temporary platforms supported by structural components of the building.
Double Layer Shell Structure

This type of Glass Roof System has been maximized to its fullest aesthetic and design potential, as demonstrated in the Esplanade Project. The façade structure consists of a double layer space frame. A top chord, a bottom chord and diagonals have been executed using the MERO Bowl Node System. Triangular panes of insulated glass with thickness of 29mm have been installed on a surface area of 10, 731 sqm. The glass panels are fixed at the corners with aluminium discs at 2 equally spaced points along the edge of each pane.

KK-System
KK-BALL NODE SYSTEM

  • Load applied to the nodes
  • Single or Multi-layer
  • Each node has up to 18 threaded holes as pin jointed connections
  • Gives greatest freedom in design

System Description
The MERO KK-System, the 1st prefabricated Spaceframe System, has a high degree of versatility in its applications. Spaceframes are filigree systems out of nodes and members. Loads are applied via the nodes, the members distributes the compression and stress forces.

The members are round hollow sections because they have the best resistance against buckling. Diameters range from 30 to 355mm with different wall thickness. The length differs from 1.5m to 5.0m but is not fixed. The nodes are balls, to give a free selection for the connection holes. The standard ball nodes have diameters from 49.5mm to 350mm. To connect several members to a relatively small node, the members will have to be conical at the ends. The members are connected via high tensile bolts. The bolt has a dowel pin and is screwed into the node via a sleeve. Compression is transmitted via the sleeve, stresses via the bolt. Single and multi-layer Spaceframes can be designed.

Design Application
Loads from cladding or suspended loads should be applied via the nodes. Membranes are directly fixed to the nodes while roofing sheets are fixed to the purlins which are attached to the nodes via a purlin stool.

Material Choices
This System can be of steel, aluminium or stainless steel.

Additional Pointers
The KK-System can be combined within on project with NK-System, BK-System or even traditional steel sections.

NK-System
NK-BOWL NODE SYSTEM

  • Double-layer structure
  • Pin-jointed connection to the nodes
  • Lower chord as ball node system
  • Plane or vurved surfaces
  • Average to wide-span structure

System Description
The MERO NK-System is derived from the double layer KK-System, with the advantage that cladding of glazing can be directly fixed on the top chord without additional purlins. Thus, a higher transparency of glazed structures is achieved.

Standard bowls have diameters from 160 to 200mm. The members of the top grid are rectangular hollow profiles, approximately 1.5 to 4.0m long. The members are pin jointed to the nodes and the screws are not visible. Members and nodes are flushed and restrained torsionally. The nodes and the members of the bottom grid such as the diagonals correspond to the KK-System.

Design Application
Loads from cladding/glazing are applied directly to the RHS profiles of the top chord. If small panes have to be considered, additional rafters can be integrated in the level of the top grid. Loads can be applied to the ball nodes of the bottom chord.

If the double layer NK-System is combined with the single layer ZK-System, the NK bowl nodes can be designed with the bend resistant connection of two screws per member.

TK-System
TK-DISC NODE SYSTEM

  • Single-layer system in triangular surface geometry
  • Pin-jointed connection to the nodes
  • Curved surfaces of small to average span structures

System Description
The disc node is the most specialized connector. It is only applicable for curved structures with triangular grids.

RHS profiles are bolted with discs nodes. The connection is a flush fitting and torsion proof. The standard nodes have a diameter of 200mm with member section ranging from 70x70mm to 90x90mm. The members with lengths of 1.5m to 3.0m are bolted and concealed.

Design Application
Loads are applied to the members. Compression, stress and shearing forces are transmitted to the nodes. If small panels have to be considered, additional rafters can be integrated. Each perimeter node has to be supported.

Additional Pointers
For wide spanning structures, the single layer TK-System can be combined with the double layer NK-System.
ZK-System
ZK-CYLINDER NODE SYSTEM

  • Single-layer structure in triangular and/or trapezoidal surface geometry
  • Bend resistant connection
  • It is used specifically for curved surfaces of average span structures
  • Small to middle spans
  • Cladding elements fixed directly on members

System Description
The cylinder node provides a bend resistant connection. Thus, plane and curved single layer constructions can be executed with triangular or quadrangular girds. The quadrangular grid is very economical with respect to cost.

RHS profiles are connected to the cylinder node by two or four bolts per member. The connection is a flush fit and torsion proof. The standard nodes have a diameter of 200mm, the member sections are from 100x60mm to 160x80mm. The members, with lengths of 1.0m to 4.0m, are screwed via bolt insertion holes.

Design Application
Loads are applied directly to the RHS profiles. The connection resists bending forces. If small panes have to be considered, additional rafters can be integrated.

Additional Pointers
For wide spanned structures, the single layer ZK-System can be combined with the double layer NK-System.

Tension Cable System

This system forms part of a Tensile Structure. This form of construction has become well understood and widespread in large structures in the latter part of the twentieth century.

In its simplest form, a Tension Structure is a line of cables arranged to form two parabolic arcs, each resisting a load applied in a particular direction, with tubular steel struts at points of support for glazing.

Tension Structures can span any number of panels over any distance. However, the larger the span, the larger the cables required and the greater the tension forces required to maintain stability and resist the applied loading. It is, therefore, important to ensure that the host structure will be strong enough to withstand the forces imposed on it by the Tension Structure.
