Functionalities? Of StairCase

A Stair is a set of Steps leading from one floor of the building to another typically inside the building. It is responsible for vertical transport within the building. Steps are also used in emergency situations.This article gives a full detailed information about types of Stair cases and their usage in different types of Building. After reading this article one will be able to create stair case designs that will be suitable for different types of Buildings.

Types Of Stair Cases

The list below specifies the different types of Stairs.

1. Straight Stair
2. Half turn Stairs
3. Winder Stairs
4. Cantilever Stairs
5. Spiral Stairs
6. Bifurcated Stairs

Straight Stairs

Straight Stairs is no change in direction between two successive floors. Straight stairs are generally use for small houses,mini bungalows and this specific type of stairs are used in that condition when there is less amount of Space and stairs runs straight between two floors.This types of staircase is also used for the single flight or double with landing.
On longer flights of stairs, a landing is inserted to break up the flight. Building codes require this for floor heights above 12 feet. Especially in commercial buildings, straight stairs often have platforms halfway up the run of the stairs.

Advantages of Straight Chairs

1. It is easier to build and it also depend on the level of detail in the design
2. Straight Chairs can only be connected at the top and the bottom
3. They work well with minimalist design homes due to their inherent simplicity.
4. Measuring for railings for straight stairs is simpler than for other stair designs.

Disadvantages of Straight Chairs

1. Straight Chairs use? a? fair amount of Linear Space.
2. Straight Chairs do not offer privacy between the floors of a residence.
3. A stair 12-feet high requires a landing to break up the span. The addition of a landing will use up a lot more space and therefore these types of stairs are seldom used in residential construction.

Half Turn Stairs

The main function of Half turn chairs is that they can change the direction by 180 degrees. It is further classified into three types.

1. Dog legged Stair
2. Open newel Half turn stair
3. Geometrical half turn stairs
4. Dog Legged stairs:

Dog Legged Stairs

Dog legged stairs come under the category of newel stairs in which newel posts are provided at the beginning and end of each flight,and this type of design is mostly constructed for educational buildings.

Open newel Half turn stair

This type of stairs has open newel half turn stairs. and this stair has a well between the outer strings.

Geometrical Half turn Stairs

In geometrical half turn stairs there is the absence of Newel Post and in this staircase there are any geometrical shape. In this staircase direction is change. and for this types we required a skillful person to construct it because there is curve and many geometrical shapes are there.

Winder Stairs

Winder Stairs are a variation of L shaped chair, instead of a flat landing, they have a pie shaped or triangular shape at the corner transition.

Advantages? Of Winder Stairs

1. The primary advantage of Winder Stairs is that they require less space than many other types of stairs. It is mainly used for the secondary staircase.
2. Winder Stairs seem to create seamless transition, visually as they meander round the corners.
3. Winder stairs are compact in nature and that is the sole reason that adds an extra glamour in interior designs of any residence.

Disadvantages of Winder Stairs

1. Winder stairs are a little harder to navigate than L stairs.
2. It can be more difficult to add a handrail to these than some of the other types of stairs.
3. Like with L shaped stairs, a center support is typically required.

Cantilever Stairs

Cantilever Stairs are created to have their stairs treads appear to be floating in the air without support. In this specific stair the stair stringer will be attached to one end of the treads and can be exposed or hidden. These? stairs add an extra grandeur to the room if crafted properly.

Advantages of Cantilever Stairs

1. Cantilever stairs create a more open and spacious aesthetic to the room.
2. The stringer is located to one side hidden in the wall which can allow for more headroom.
3. Cantilever Stairs stirs visual interest and are more unique than any other stairs.

 

Disadvantages of Cantilever Stairs

 

1. The design of the structure should be taken into consideration to support Cantilever stairs
2. Tread supports need to be designed to handle the weight and potential torque.
3. Due to structural requirement Cantilever stairs are more expensive.

Spiral Stairs

These stairs are quite similar to circular stairs except that the radius of the curvature is small and the stairs may be supported by a Centre Post.

Advantages of Spiral Stairs

1. One of the key advantages of spiral stairs is their compactness. They are very popular on beach front decks where space is at a premium. They are also used extensively on city lofts for the same reason.
2. Spiral stairs can be attractive and there are many variations on railings styles which can have a major impact on the overall appearance of the stair.
3. Since the center pole and landing typically provide the structural support for the stairs, they do not need much in the way of extra support structures, making installation easier than with many other types of stairs.

Disadvantages of Spiral Stairs

1. It is very difficult to carry large items in Spiral Stairs
2. Only one person can go? up and down in Spiral Stairs.

Bifurcated Stairs

Bifurcated Stairs are a wide set of stairs starting from the bottom that ends at a landing partway up the flight . The stairs splits at the landing into two narrower sets of Stairs leading in opposite directions

Advantages of Bifurcated Stairs

1. Bifurcated Stairs acts in a dual role, by leading up to different sections of the building making each end of the upper level easily accessible.
2. They add an impressive architectural design statement to the building.
3. Typically used in large homes or commercial buildings as a Grand Entry. They are suitable for interior or exterior locations.

Disadvantages of Bifurcated Stairs

1. Bifurcated stairs require a large amount of space
2. Bifurcated stairs are not so pocket friendly. Therefore one needs to think minutely while designing Bifurcated stairs for the interiors of the residence.

Conclusion

When listing the primary elements of a house design, the staircase is the first integral part to be named. A staircase location in the new layout of the particular? building establishes a major decision, as this often dictates the layout of the entire property. The sole purpose of stairs is easy means of moving between levels. In modern Construction Engineering the structure of a staircase can serve as: a partition to break up a large open-plan area, a home's sculptural centrepiece, or even as a creative storage option. Cupboards can be installed below them, they can be adapted to hold bookshelves and drawers can be installed in the risers. Thus a well designed stair case can last for generations without being replaced and proves a vital part of the house layout.
