CONSTRUCTION DETAILS OF CAVITY WALL:- A cavity wall is constructed of two leaves that is inner and outer with a hollow space in between them. The width of cavity varies from 50mm to 100mm and it stands vertically. The outer is generally of 1⁄2 brick thickness and the inner wall may be of 1⁄2 of 1 brick thickness. The two portions of the wall are connected by means of metal ties or specially prepared bonded bricks. The metal ties are generally of wrought iron or mild steel and they are coated with tar or galvanizedso as to have protection against rust. Where corrosion is heavy, the metal ties of copper or bronze may be adopted. The metal ties are placed at a horizontal distance of 900 mm and a vertical distance of 450 mm. The arrangement of ties is kept staggered . The outer wall is generally constructed in stretcher bond , but it may be constructed in the flemish bond or english garden-wall bond or flemish garden-wall bond by using bats for headers. As far as possible, there should be no intimate contact between two leaves of the cavity wall. - Study24x7
