Vinyl & Cork Underlay

BGC Vinyl & Cork Underlay sheets have been designed to provide a smooth, durable and completely termite and rodent proof surface on which to lay vinyl and cork tiles and parquet floors.

Vinyl and Cork Underlay sheet are immune to water damage and will not swell. The sheets are completely termite and rodent proof.

Vinyl & Cork Underlay:

• provides a smooth base on which to lay vinyl or cork flooring.
• durable and easy to work with.

6.0 Design Approach

There are 2 methods of construction – typical and tie-down. Typical is the most common method of building whilst the tie-down method is required for cyclonic or high wind areas (as determined by an engineer). This guide provides information for both building methods.

Important Note

It is the responsibility of the architectural designer and engineering parties to ensure that the information in the Hebel PowerBlocks Design and Installation Guide is appropriate for the intended application. The recommendations of this guide are formulated along the lines of good building practice, but are not intended to be an exhaustive statement of all relevant data. Hebel accepts no responsibility for or in connection with the quality of the recommendations or their suitability for any purpose when installed.

Scope

The Hebel PowerBlocks Design and Installation Guide has been created to provide information for detached residential buildings. The design information in this guide has been condensed from the Hebel Technical Manual and AS3700 Masonry structures. The design basis is AS3700 Masonry structures, Section 12 Simplified design of masonry for small buildings. The footing and slab design is based on AS2870 Residential slabs and footings – Construction.

Refer to Table 6.1 for Building Geometry Limitations.

Design Parameters

The structural design information in this guide is based on the data and assumptions in Table 6.2, 6.3 and 6.4.

Design Sequence

Fig. 6.1 details Hebel recommendations for how to design a Hebel PowerBlock home.

Table 6.1: Building Geometry Limitations

 2 storeys max
 Max. height to underside of eaves  6.0m
 Max. height to top of roof ridge  8.5m
 Max. building width incl. verandah but not eaves  16.0m
 Max. building length  5x width
 Max. lower storey wall height  3.0m
 Max. upper storey wall height  2.7m
 Max. floor load width on external wall  3.0m (6.0m single span floor)
 Max. roof load width on external wall  3.0m (6.0m rafter/truss span)
 Max. floor load width on external wall  6.0m

Where the building geometry is outside the above limitations, the designer must refer to the Hebel Technical Manual and AS3700 Sections 1-11.
