BILDA is an innovative technology for assembly of structures and mechanical ﬁxing of cladding panels which comprises the following basic components:
BILD-ing kit. А modular set of square proﬁles, Q-channeled at corners, and versatile elements that can form various structures through quick dovetail coupling – from ﬂat grids to spatial constructions and entire independent structures. These can incorporate mechanically ﬁxed layers to form cladding skins for facades or other applications. BILDA components are produced from aluminium alloy EN AW 6063-T6.
Cladding method. А precision slot technique that allows for innovative slot-and-blade
attachment of the skin elements to the substructure. The precision slot is a minimally invasive cut in the side of the panels that spares their thickness and their strength, respectively. The blades of the ﬁxing clips tie back the panels by penetrating the slots. The ‘slot- and-blade’ connection also allows for even distribution of stress from horizontal load.
Know-how. Assembly rules, detailing, technical data, instructions and methodology, precision slot milling guidelines
– all developed through study, modelling, testing and practice.
Slotting machinery. Patented machinery and tools for milling the precision mortise slots in panels by a low-cost cutting process. A range of eﬃcient rigs for the factory and construction site as well as handheld machines is available.
These are equipped with cutting discs for all cladding materials.
Features & Advantages
Versatility. The modular set of elements can be used to just cover walls and create simple cladding layers. It can also help model the cladding layer in a ‘bas relief’ manner or create ‘haut relief’ features and façade elements.
Low cost. BILDA accomplishes structures of excellent strength- to-cost ratio due to its integrity. Labour time is saved through quick connections. Panel thickness may be reduced via the ﬂat precision slot. Slots are the easiest cladding panel mortise due to machining through cutting.
Universality. A wide range of ﬁxing clips of diﬀerent size and shape can support panels from all materials, of diﬀerent thickness and conﬁguration. The clips, in addition to the preferred ‘slot- and-blade’ method, can handle all known ﬁxing methods - the ‘hole-and-dowel’, ‘undercut’ of diﬀerent types, etc. These can be employed next to each other.
Basic assemblies. Vertical strut assembly - mainly for ‘landscape’ orientation of the cladding panels. Horizontal strut assembly - mainly for ‘portrait’ orientation of the cladding panels.
Pre-planned solutions. For feature nodes within the cladding areas (corners, reveals, copings, etc.) and for interface fragments (to curtain walls, windows, doors, roofs).
Regulations. BILDA cladding system has been designed and executed in accordance with European building regulations:
EN 1990: Eurocode – Basis Structural Design
EN 1991: Eurocode 1 – on Structures
EN 1999: Eurocode 9 – of AluminiumStructures
DIN 18516-1:2010-06–Cladding for external walls, ventilated at rear.
Vertical Strut Assembly
The bracket (A) is the base element of the system. It is attached to the external wall of the building and carries all other elements of the structure. It transfers the loads applied on the cladding to the main structure of the building.
The traverse (B) is attached to the bracket by self-drilling screws. Its function is to hold the strut while allowing for its vertical movement where necessary.
The strut (C) and the traverse are fitted together (they can be pre-fitted) and the strut is secured to the traverse by means of self-drilling screws. The so formed unit is then fixed to the bracket. The strut and the traverse can form two types of connections: fixed and sliding point.
The yoke (D) is attached to the strut by means of a tongue fitting into the strut groove on one side, and by means of self-drilling screws again fitting into the parallel strut groove. Its function is to carry the clips and to distribute the load evenly onto the strut.
The yoke clips (E) are hooked to the yoke. Their function is to support the cladding panels.
Horizontal Strut Assembly
The bracket (A) is attached to the external wall of the building and carries all other elements of the system. It transfers the loads applied on the cladding to the main structure of the building.
The traverse (B) is attached to the bracket. Its function is to hold the strut while allowing for its horizontal movement where necessary. The traverse and the strut are pre-attached and the so formed unit is fixed to the brackets.
The strut (C) is slid onto the yoke, guided by its grooves.
The strut clips (D) are hooked to the strut. Their function is to support the cladding panels.
