256 Barry’s Advanced Construction of Buildings Cavity wall Joint sealed with mastic Double fin to form movement joint Figure 4.96 Movement joint in fin wall. are tilted by crane into position. This technique has been used principally for the construction of single-storey commercial and industrial buildings on open sites where there is room for casting and the necessary lifting equipment. Tilt-up construction has been used quite extensively in the US, where it originated, and many other countries such as Australia and New Zealand, for the speed of casting and speed of erection of the panels. The technique is most economical when there is a high degree of repetitiveness in the structure and the walls are used in a loadbearing capacity. Typical applications include low-rise warehouses, offices and factories. There are few examples of this type of construction in the UK. The concrete panels provide good resistance to the penetration of rain and also provide good durability and freedom from maintenance. Panels also provide good fire resistance, resistance to the passage of sound and relatively good security against forced entry. The reinforced concrete panels do not provide adequate thermal insulation for heated buildings. Thermal insulation is usually applied to the internal face of the panels with a moisture vapour check between wall and insulation. Insulation boards are used to provide both insulation and an internal finish to the building, fixed to timber battens which are shot fired to the panel. Tilt-up concrete panels vary in size, shape and thickness, but typically will be around 7 × 5 m, 160 mm thick, and weigh between 20 and 30 tonnes. Panel size is limited by the strength of the reinforced concrete panel necessary to accommodate the stresses induced in the panel as it is tilted from the horizontal to the vertical and also by the lifting capacity of the cranes. Wall panels may vary in design from plain, flat slabs to frames with wide openings for glazing, provided that there is adequate reinforced concrete to carry the anticipated loads. A variety of shapes and features are made possible by repetitive use of the formwork in the casting bed, and a variety of external finishes can be produced, ranging from smooth to textured finishes. Sequence of assembly The sequence of operations is shown in Figure 4.97. The site slab of concrete is cast over the completed foundations, drainage and service pipework and accurately levelled to
