ABSTRACT
Knowing what fixings to use to fix timber together or to other materials and surfaces such as walls, ceilings and floors, etc, comes with few rules other than trade experience and is not normally specified by the architect or structural engineer. However, there are some exceptions to this, usually when structural stability is dependent upon certain fixings. For example, the maximum spacing of galvanized restraint straps at roof level is not determined by the carpenter who fixes them, but by British Standards’ Codes of Practice and the Building Regulations. The majority of fixings, therefore, are determined by the carpenter and details of these will be stated as we progress through each section of this book. Fixing devices such as framing anchors, joist hangers, restraint straps, metal banding and panel adhesive, will also be detailed and dealt with in other chapters.
