Lockset Works

The Purpose

Lockset work is undertaken during building extension, elevation designing, building structural change and column post extension works.

The Process

In the earlier days, to extend a slab or beam, its front portion is broken upto one feet, its old iron rods are pulled out and the new iron rods welded with them.

Instead of this method, nowadays Lockset procedure is being used. In this method, for example, to join a 8 mm rod to a front portion of a slab or a beam, the slam or the beam has to be drilled for atleast 10 mm diameter and 5 inches depth. Next, it has to be cleaned using an air gun and chemical filling is done into the hole using a chemical pump. After that, the 1.5 feet long rod with the 8 mm diameter should be fitted into the hole. Now, the side gaps should be filled fully with the chemical hardening agent and be allowed to dry for about two hours.

After the hardening process is over, try to remove or move the rods sidewards. It will not be possible. The hardness will be such that even if you try to remove the rod with the power of elephant also, the rod is unmovable which proves the strength of the Lockset process.

Different sizes of rods can be used in the Lockset method and they are 8 mm, 10 mm, 12 mm, 16 mm, 18 mm, 20 mm and 25 mm. The hardening chemical agents used are from popular brands such as Fischer, Bostik and Fosroc.
