Improvements in or relating to wall systems

摘要

A modular wall system ( 1 ) for constructing temporary buildings such as warehouses comprises a plurality of elongate panel members ( 2 ) arranged to extend horizontally between a pair of upright support members ( 3, 4 ). The panel members ( 2 ) are stacked one on top of another in a vertical plane to form a wall of the desired height wherein adjoining edges of adjacent panels ( 2 ) are provided with interlocking tongue and groove formations ( 7, 8 ). At least some of the panel members ( 2 ) are provided with an elongate reinforcing member ( 20 ) extending lengthwise of an internal longitudinal chamber ( 13 ) to assist withstanding wind forces. The reinforcing members ( 20 ) are constructed and arranged to have a higher resistance to forces applied in a direction (C) normal to a vertical plane of the wall than parallel to the vertical plane of the wall.
