The Indian Standard IS :1946 (1961) outlines the code of practice for using fixing devices in walls, ceilings, and floors of solid construction. Adopted on November 23, 1961, it was developed to improve the use of fixing devices such as expansion plugs and bolts in building construction, aiming to ensure stronger, more durable fixtures with minimal damage to structures.
The standard emphasizes the need for precise hole drilling corresponding to the fixing device’s dimensions to ensure a strong grip and proper fixture installation. It details the use of various fixing devices, including expansion wall plugs, expansion shells, and caulked-in anchor devices, which are inserted into pre-drilled holes and expand to secure the fixture.
Special attention is given to materials and construction of these devices to ensure they are durable, termite-proof, and damp-proof where necessary. The document specifies the conditions under which different types of plugs should be used, based on environmental factors like presence of vibrations, temperature extremes, or corrosive chemicals.
Additionally, the code provides detailed guidelines on the selection of the appropriate size and length of plugs based on the load requirements and the specific installation environment. It also covers the proper methods for installation, ensuring that the fixtures are installed with a high degree of safety and reliability.
Overall, IS:1946 (1961) is a crucial standard for the construction industry, guiding the proper use and installation of fixing devices to enhance building safety and integrity.
