Components of Wooden Stairs
As we know, a staircase comprises of so many components but there are three major components of wooden stairs:
01. Wooden Steps
02. Wooden Stair Landings
03. Wooden Stringers
Let us get introduced to each of these major components of timber staircase. Along with an introduction, we have provided some prescriptive design dimensions. These dimensions are for preliminary guidance only because component sizes cannot be determined by customary data collection as this calculation varies with different classes of timber. Hence, based on relevant standards like, Indian standards, British standards, etc., we are providing here with some minimum dimensions for these components:
01. Wooden Steps:
i. Wooden Steps of a stair basically comprise of wooden tread, wooden riser, nosing and angle blocks.
ii. Wooden Tread is a part of the staircase made from wood, which is horizontal to floor, on which a person steps while, walking between the floors. The thickness of the wooden tread should not be less than 35 MM.
iii. Wooden Riser is the vertical member between the two wooden treads. The minimum thickness of wooden riser should be 25 MM or more.
iv. Wooden Treads and Wooden Risers are mostly joined together by tongue and groove joint.
v. Ensure that the nosing of the edge should not project more than the thickness of the wooden Tread beyond the wooden Riser.
vi. Angle blocks are triangular sections of wood glued in internal angles between the underside of treads, risers and strings to strengthen the right-angled joint between the treads, risers, and stringers.
02. Wooden Stair Landings:
i. Wooden Stair Landings are boarding on joists and supported on walls.
ii. Wooden Stair Landings are joined with tongued and groove joints.
03. Wooden Stringers:
Wooden Stringers are the inclined wooden member used to support the wooden steps. These wooden members should be around 30 – 50 MM thick and 250 – 380 MM deep.
There are 4 types of wooden stringers:
i. Cut Stringer:
Cut stringer improves stair appearance. It has its upper surface cut to receive wooden tread and wooden risers. Its lower edge is kept parallel to the pitch of the wooden stairs.
ii. Housed Stringer:
Housed stringer has its both top and bottom edges parallel to pitch of stairs. Grooves’ are provided for receiving treads and risers. These treads and risers are generally nailed, glued, and wedged to the stringer.
iii. Rough Stringer:
In wider stairs, the rough stringer, which renders intermediate support to the wooden steps is provided.
iv. Wreathed String:
The Wreathed string is a curved stair string.
Types of the Wooden Staircase
The wooden staircases are classified into multiple types depending on two major categories, as stated under:
Case 1: Types of wooden staircase based on their functional requirement
Case 2: Types of wooden staircase based on latest trends
So, let’s see both the above-stated cases:
Case 1: Types of Wooden Staircase Based on their Functional Requirement
The primary function of stairs is to provide access to principle spaces on different floors. Thus, to achieve its functional requirement, stairs are classified into various types based on their functional requirements.
Let us see different types of wooden staircase based on their functional requirement:
01. Straight Wooden Stairs:
Straight Wooden Stair is one of the most common types of stairs found in residences. It is a type of stair, in which no change in direction of stair’s flight is observed.
02. Half Turn Wooden Stairs:
Half Turn Wooden Stairs is a type of straight wooden stair, which bends in other direction at the mid-way of flight at landing. These stairs are comparatively safer and more comfortable than straight wooden stairs.
03. Quarter Turn Wooden Stairs:
Quarter Turn Wooden Stairs structure is a type of wooden stair that bends in a different direction closer to the top or bottom of the stairs. Even these stairs are comparatively safer than straight wooden stairs.
04. Curved Wooden Stairs:
Curved Wooden Stairs follow a helical arc. We can use curved wooden stair for aesthetic purposes in our home. They however prove costly, as it consumes more wood.
05. Circular Wooden Stairs:
Circular Wooden Stairs are spherical in constructional plan. In this type of stair, the step does not radiate a central pole. Also, circular wooden stair gives a grand appearance, as they have a minimal diameter.
06. Spiral Wooden Stairs:
Spiral Wooden Stairs, with different shapes and various configurations, can be an iconic element of a house. They occupy very smaller area than other staircases. They are however not very comfortable and even less safe.
07. Bifurcated Wooden Stairs:
Bifurcated Wooden Stairs gets bifurcated in two directions from the landing. This type of stairs has a wider flight at the bottom, and the stairs’ width decreases after the landing.
Let us now see some more types of latest and trendy wooden staircases.
Case 2: Types of Wooden Staircase Based on on-going Trends
Along with the stairs’ functional requirements, it’s essential to go parallel with the modern on-going trends.
01. Space Saving Wooden Stairs:
We can use the Space Saving Wooden Stairs mostly when the space in our house is limited, and we can’t afford to spare more area for the construction of stairs. We can adopt different exciting design ideas to save space.
02. Mono-Stringer Floating Wooden Stairs:
Monostringer Floating Wooden Stair consists of a mono stringer, which is a single spline stringer designed to provide architectural features to the house, as well as to provide support to the treads of the staircase.
03. Floating Wooden Stairs:
Floating Wooden Stair is a type of stair that gives the impression that the treads of the stair are floating in the air. These floating wooden stairs are mostly popular in an open concept space for a house.
04. Wooden Stair with Storage:
The space under the stairs can be a great spot for making the closet when there is limited space for storage in a house. Even we can add doors to conceal the space under the stair.
05. Modern Suspended Wooden Stairs:
Modern Suspended Wooden Stairs are the type of stair suspended in the air. These stairs are incredibly light in weight that appear like the wings holding each step as though they were feathers.
Along with wooden components, even some non-wooden materials can be incorporated into wooden stairs to increase its elegance and attraction. Now, let us get familiar with various non-wooden materials and their uses to enhance the charm and attractiveness of stairs.
Variety of materials used with wood for timber stair construction
For the construction of stairs in different shapes and styles, the non-timber materials mostly used for the construction of wooden stairs are as following:
Let’s have a look at both these non-timber materials used along with wood for timber stair construction.
