Brick nogging partitions — method of construction Brick nogging type partition walls are constructed by which of the following methods?
-
ALaying bricks as stretchers in cement mortar as a freestanding wall
-
BLaying bricks as headers in cement mortar as a freestanding wall
-
CReinforcing a brick wall with iron straps only
-
DBuilding brickwork infill within a timber (wooden) framework
-
ENone of these
Answer
Correct Answer: Building brickwork infill within a timber (wooden) framework
Explanation
Introduction / Context:Brick nogging is a traditional method for creating lightweight internal partitions and for infilling timber frames. It combines the speed and economy of brickwork with a structural timber skeleton that carries the main loads, leaving the nogging primarily as infill and for stiffness and fire separation.
Given Data / Assumptions:
- Partition (non-loadbearing) application.
- Conventional timber studs and rails forming bays.
- Thin brick units laid within the bays.
Concept / Approach:In brick nogging, brickwork is built inside a timber frame between studs and rails. The timber frame resists vertical loads; the brick infill adds mass, fire resistance, and some lateral stiffness. This is distinct from a standalone brick wall (stretchers or headers) and from mere strapping of a wall with iron bands. Proper ties and allowances for movement between brick and timber are necessary to avoid cracking.
Step-by-Step Solution:
Identify primary structural system: timber frame carrying loads.Recognise nogging: brick infill within the frame bays.Select the method describing brickwork within a wooden framework.Verification / Alternative check:Historic half-timbered construction and modern adaptations illustrate brick nogging between timber members, often with lath and plaster finishes over.
Why Other Options Are Wrong:
- (a) and (b) describe freestanding masonry bonds, not nogging.
- (c) Iron straps alone do not define nogging construction.
- (e) Incorrect because (d) is correct.
Common Pitfalls:Rigidly connecting nogging to timber without movement joints; inadequate tying leading to gaps; moisture incompatibility between materials.
Final Answer:Building brickwork infill within a timber (wooden) framework
