Following are the various components of a staircase: Parts of a staircase. Source: DIY DOCTOR A step is composed of tread and riser. Tread is a scrap of the stairway that is stepped in. It is the top or horizontal surface to press beneath the feet.
A stair is a series of steps arranged in a manner to connect different floors of a building. Stairs are designed to provide easy and quick access to different floors. No. of step in a flight should be restricted to a maximum of 12 and a minimum of 3
A quick crash course in common staircase terminology can effectively change that, however, and it can help ensure that you’re able to easily communicate your wishes and needs with your designers, contractors and stair parts providers. So, what are the primary components of a staircase, and what’s the main purpose of each?
The material of the tread can be timber, steel, glass, acrylic, panel product or tiling. A standard straight run of stairs in a residence, the minimum depth is 10 inches.
The treads of your staircase are the flat, horizontal parts that you actually place your feet on when ascending and descending. Treads can come in a variety of materials, including wood and metal, and you can also add carpeting or other anti-slip solutions to your treads in accordance with your needs.
The newel posts refer to the more substantial vertical components that typically appear at key structural points, while the balusters, which are also known as “spindles,” are the smaller, sometimes more decorative vertical elements that often appear between the newel posts. Both newel posts and balusters present prime opportunities for customization, and you can typically choose from a wide range of materials and styles when designing them.
You don’t actually place your feet on your staircase’s risers, and in some cases, your stairs may not have risers at all. Spiral staircases and outdoor deck steps, for example, often lack risers, whether for safety, aesthetics or what have you, but they still have a rise.
The different parts of stairs are as follows: 1. Step: It is a combination of tread and riser which permits ascent and descent from one floor to another. 2. Tread: The upper horizontal portion of the step over which foot is placed during ascend ing or descending a stairway is known as tread. 3.
Pitch or Slope: The vertical angle made by nosing line of the stair with the horizontal is known as pitch or slope of the stair . 14. Run: The total length of the stair in horizontal plane including lengths of landings is known as run of the stair.
5. landing: A horizontal platform between two successive flight of a stair is called landing. Landing is used as a resting place during use of the stair. It facilitates the change of direction of the flight. Landing which extends for full width of the staircase is known as half-space landing. Landing extending for only half the width ...
The vertical height between the tread of one flight and the ceiling of the overhead construction is known as head room. Head room should be sufficient so as not to cause any difficulty to the persons using the stair. Head room is also known as head way.
It is an imaginary sloping line parallel to the slope of the stair and touching the nosing of all the treads. 21. Walking Line: It is the approximate line on the stair, adopted by the people during the use of the stair. This line is located about 40 cm from the centre of the handrail.
It also acts as a protective bar. 11. Baluster: It is an individual vertical member made of timber, metal, or masonry and fixed between string and hand rail to provide support to the hand rail. 12. Balustrade: Framework made from series of balusters and hand rail is known as balustrade. It is also known as barrister.
Hand rail: It is an inclined rail provided at convenient height over balustrades. The inclination of the rail is parallel to the slope of the stair. It serves as a guard rail and provides assistance to the users of the stair. hand rails can be molded in so many architectural forms. It also acts as a protective bar.
Tread is a scrap of the stairway that is stepped in. It is the top or horizontal surface to press beneath the feet. It is trodden on while climbing or descending the staircase. It is constructed to the same thickness as another flooring. There is always one fewer tread than risers in a staircase. The overall horizontal distance of the stairs will be the number of threads added together.
Nosing. Nosing is the horizontal, protruding edge of a stair where most foot traffic occurs. Mostly, it is the half rounded molding fixed to the ends of the threads exposed in a half which covers where the balusters fit into the treads.
The word easing refers to any type of hand railing change in direction. Wall handrails are mounted directly onto the wall with wall brackets. At the bottom of the stairs, such railings flare to a horizontal railing and horizontal portion is called a starting rising. At the top of the stairs, the horizontal portion of the railing is called - over easing. Up easing is an element of a handrail that allows changing the direction of a handrail from angular to vertical.
The riser is the vertical portion between each tread on the stair. Not all stairs have risers. The rise-less steps are known as the open thread. Open riser stairs have grown in popularity in recent years. Closed tread stair has risers included. The vertical board forms the face of the step, also forms the space between one step and the next.
A volute is a handrail end component for the curtail or bullnose footsteps that curve inward like a spiral. It is said to be left or right-handed depending on which side of the handrail is as one faces up the stairs. The detail is like a scroll at the entry of a handrail, sometimes called a monkey's tail. Available with an up-ramp, it is installed at the bottom of the side on a starting step, extending out from the side of the staircase. However, it has the most difficult installation process you can find in a staircase.
The greatest riser height within any flight of stairs shall not exceed the smallest by more than 3/8 and the rise shall not be less than 11 inches. Check the local building codes on stair riser height if you are building your own staircase.
Stair nosing helps to improve the visibility of wooden stair edges.
Generally, they are provided at the rear of a building to access for serving various floors. When viewed above appear to Fallow a circle with the single center of curvature and large radius. Components of staircase
Wooden stairs –. As they are light in weight, mostly used for residential building. The main objection to this stair that it is easily attacked by fire and thus in the fire, the occupants of the upper floor can’t escape. If it is made from good timber like teak, sal, etc.
Staircase – A staircase, stairwell, flight of stairs, or simply stairs is a construction designed to a large vertical distance by dividing into the smaller vertical distance is called steps stairs. A stair is a series of steps arranged in a manner to connect different floors of a building.
Going – it is a horizontal distance between the faces of two consecutive risers. Handroll – inclined rail over the string. Generally, it is molded. Headroom – vertical distance between noising of one light and bottom of flight immediately above is called the headroom.
Requirements of staircase. No. of step in a flight should be restricted to a maximum of 12 and a minimum of 3. A staircase is an enclosure that contains the complete stairway. In a residential house may be provided near the entrance. In public buildings, stairs must be from the main entrance and located centrally.
Rcc stairs –. Commonly used in all types of construction. They resist better fire and wear than any other material and can be molded to the desired shape. The step can be provided with a suitable finishing material such as marble, terrazzo, tile.
Scotia – an additional finish provided to noising to improve the elevation. Soffit – under the surface of a stair. Generally, it is covered to a ceiling or finished with plaster. Step – a combination of tread and riser. Tread – it is an upper portion of the step.
