Thickness Of Concrete Walls Architecture

Axis distance is measured from the surface of the concrete to the centreline of the main reinforcing bars.

Thickness of concrete walls architecture.

There are various architectural concrete surface finishes for. In general poured concrete basement walls that are 8 feet tall or less and have no more than 7 feet of soil pressing against them from the outside function well at a thickness of 8 inches. There are some basic rules of thumb for foundation wall thickness and these are outlined in many modern building codes. 2 5 clear to strength steel 4 10 rather than the designed 5 10 bending strength of the section has been reduced by about 35.

The exterior wythe can be thickened to accommodate architectural details. As with typical wall panels the panels are cast in a flat orientation so the form side is generally the side that will be exposed to view in the final construction. The length to width ratio of the panel formed by the surrounding control joints should be limited to 1 5. 4 to 15 ft.

Slab on ground control joint spacing is typically limited to between 24 and 30 times the slab thickness. Varying thicknesses interior and exterior wythes are typically 1 3 4 thick. The aspect ratios of length width and thickness of a concrete slab are limited by control joints and construction joints. Shapes an assortment of architectural elements such as cornices bullnoses and reveals can be cast into the concrete carefully and cost efficiently.

Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well. The thickness of reinforced concrete walls is affected by the fire rating of the structure to which they are to form a part. Minimum cover to reinforcement to be kept at 20mm. Exterior wall thickness depends on siding material.

Architectural concrete stays permanently exposed to view on surfaces of completed structures making important for the contractor to work with precision. For brick walls a common thickness is 230mm 9 and for concrete block walls common thicknesses are 200mm 8 150mm 6 and 100mm 4. Standard 2 by 4 studs are 3 1 2 inches wide and drywall is 1 2 inch thick so interior walls are usually 4 1 2 inches thick. The recommended maximum is 12 inches.

Architectural concrete construction needs special care in the selection of materials forming placing and finishing in order to achieve the designated architectural appearance. 5 to 12 in including 1 to 4 in. When a taller wall or a higher level of soil or both come into play the thickness should increase to 10 inches. The thickness of interior walls is dictated by stud width and wall covering.
