REINFORCED CAVITY WALL

INTRODUCTION :

A WALL CONSTRUCTED IN TWO LEAVES OR SKINS WITH A SPACE OR CAVITY BETWEEN THEM IS CALLED A CAVITY WALL.
USED AS AN EXTERNAL WALL.
THE MAIN PURPOSE OF CONSTRUCTING A CAVITY WALL IS TO PREVENT THE PENETRATION OF RAIN TO THE INTERNAL SURFACE OF THE WALL.
IT MAY OR MAY NOT BE REINFORCED.

ACCORDING TO BUILDING REGULATION RULES :

THE CAVITY SHALL NOT BE LESS THAN 50 MM NOR MORE THAN 75 MM IN WIDTH AT ANY LEVEL.

EACH LEAF SHALL NOT BE LESS THAN 100 MM IN THICKNESS AT ANY LEVEL.

FOR A NOMINAL 255 MM WIDE CAVITY WALL OF ANY LENGTH THE MAX. HT. IS 3.6 M & FOR LENGTH NOT EXCEEDING 9 M , THE MAX. HT. IS 9 M.

INNER LEAF CAN NOT BE LESS THAN 75 MM THK. IF THE WALL FORMS PART OF APRIVATE DWELLING HOUSE OF ONE STOREY OR IS THE UPPER STOREY OF SUCH A DWELLING HAVING ONLY TWO STOREYS.

A GAUGE MORTER NOT WEAKER THAN 1:2:9 SHOULD BE USED.

ADVANTAGES :

IT IS ABLE TO WITHSTAND A DRIVING RAIN IN ALL SITUATIONS FROM PENETRATING TO THE INNER WALL SURFACE.

NO NEED FOR EXTERNAL RENDERING

GIVES GOOD THERMAL INSULATION,KEEPING THE BUILDING WARM IN WINTER & COOL IN SUMMER.

ENABLES THE USE OF CHEAPER & ALTERNATIVE MATERIALS FOR THE INNER CONSTRUCTION.

POSSESSES HIGHER SOUND INSULATION VALUE THAN A STANDARD BRICK WALL.

DISADVANTAGES :

REQUIRES HIGH STANDARD OF DESIGN & WORKMANSHIP TO PRODUCE A SOUNDLY CONSTRUCTED WALL; THIS WILL REQUIRE GOOD SUPERVISION DURING CONSTRUCTION.

SLIGHTLY COSTLIER THAN A STANDARD 1 BRICK THK. WALL.

IT IS NEEDED TO INCLUDE A VERTICAL D.P.C. TO ALL OPENINGS.

CAVITY BLOCK CONSTRUCTION
HOLLOW CONCRETE BLOCKS ARE USED FOR THE CONSTRUCTION.
DIFFERENT SIZES & TYPES OF BLOCKS ARE AVAILABLE.
THE TYPE OF BLOCK DEPENDS UPON WHERE IT IS TO BE USED.

CONTEMPORARY CITY FOR THREE MILLION INHABITANTS

Urban design by Le Corbusier, 1922 Exhibited in 1922 at the Salon d’Automne in Paris, the Contem-porary City for Three Million Inhabitants was Le Corbusier’s first comprehensive urban-planning project. Accompanied by a 100-square-meter diorama, it consisted of a rigidly geometric, centralized orthogonal plan with monumental axes, uniform modern buildings, vast expanses of open space covering 85 to 95 percent of the surface, and a system of highways. The project was seen simultaneously as a breathtaking modern vision and as the destruction of the familiar urban setting. Influence on the project ranged from American gridded cities, Peter Behrens’ work, and Tony Garnier’s Une Cité industrielle (1901–04, 1917; An Industrial Town) to Bruno Taut’s Utopian Die Stadtkrone (1919; The City Crown). By 1922 Le Corbusier was one of the major figures of the Modern movement, and the Contemporary City marked a high point in a period of extraordinary activity. It incorporated two ideas that he had been...

DOM-INO HOUSES

Housing design by Le Corbusier, 1914–15 and later Between 1914 and 1915, Le Corbusier, partly encouraged by his friend Max du Bois, conceived of a standardized system of construction using reinforced concrete, which was to provide the structural basis of most of his houses through the mid-1930s. These were the Dom-ino prefabricated houses with independent skeletons. The frame was to be completely independent of the floor plans of the houses. Derived from the Hennebique frame, it consisted of six thin concrete columns that simply carried two horizontal slabs as the floors. The columns and slabs were connected by staircases. Apart from this structural core of the houses, nothing else was fixed, thus permitting a great flexibility to suit demands on the basis of aesthetics, climate, composition, or view. The floor plan was also extremely flexible, as interior partitions were independent of the grid. This utterly simple and clear “open plan” method did away with load-carrying walls. Suppor...
