Building panel construction

摘要

The invention relates to a method of constructing reinforced, filled and set walls. Each panel comprises construction boards 1 held apart from each other by spaced apertured metal strength members 2, forming a sandwich construction. Each strength member is provided with at least one bar (10 figure 3) extending beyond an edge of the construction boards. Each strength member 2 has a bar receiving portion (see figures 3a, b) associated with its end opposite the at least one bar. To construct a wall, a first such panel is first erected with its strength members extending vertically and with the bars projecting above the remainder of the panel. The void between the construction boards is then filled with a settable material such as cementitious material. A second panel is located vertically above the first by slotting the bars of the first panel into bar receiving portions of strength members in the second panel. Thereafter, the void between the construction boards of the second panel is filled with the settable material. Lateral reinforcement 3 may be provided by a plurality of steel bars 9 extending horizontally through respective openings 7 in the strength members. Later embodiments relate to a strength member for use in the manufacture of pre-formed hollow panels, and a pre-formed hollow panel for use in a method for constructing reinforced, filled and set walls.
