Connections, Span Tables and Graphs

 

Maximum spacings of fasteners for horizontal installation

Maximum spacings of fasteners for vertical installation

 

Shear strength per fastener for the following connections

Note
The design capacities for the fixings are generally significantly less than the manufacturers design capacities because of deformation of the fixing holes. We have used the lesser of the two values.

 

Maximum wall height

Use of Tables

  1. Determine the loads on the Speedwall in accordance with NZS 4203 1992 or AS/NZS 1170.0 as applicable.
  2. Use Table 1 and/or Figure 1 to ensure that walls spanning horizontally can carry the loads previously calculated. Use Table 2 and/or Figure 2 to ensure that walls spanning vertically can carry the loads previously calculated. Interpolation of points in the tables is allowed.
  3. The Tables and Graphs have been generated for a range of deflection limits i.e. Span/150 Span/200 Span/250 Span/ 300 in both the vertical and horizontal panel configurations.
  4. The walls must be checked for both ultimate limit state loading (ULS) and serviceability limit state (SLS) loading.
  5. Vertical Wall Tables and Graphs have been generated to a maximum of 8m height.
  6. Horizontal Wall Tables and Graphs have been generated assuming a 14m high wall. This is the maximum wall height.


Boundary members and openings
The Speedwall walls must be supported on all edges and around the perimeter of all openings. The connection between the walls and the boundary members and the boundary members themselves must be specifically designed to carry the loads from the Speedwall® walls.
Boundary member loads must not be transferred to the Speedwall panels.

The fastener strengths shown in this section may be used to design the connections. Maximum spacing of fasteners is shown on page 8. Refer to Section 6 for installation information.

Installation note
All C Track to Structure, C Track to Speedwall and Speedwall to Speedwall connections shall be in accordance with details specified in this manual unless specified otherwise by the Project Engineer.
