Bridle: This is a member used to bridge a wall opening; supports one end of the putlog at the opening.
What are the parts of scaffolding called?
Scaffolding contains the following parts.
- Standards: The vertical posts (also called uprights).
- Ledgers: The horizontal members parallel to the wall.
- Braces: The bracing system.
- Putlogs: Horizontal members normal to the wall.
- Transoms: Putlogs whose both ends are supported on ledgers in double scaffolding.
How many types of scaffolding bracing are there?
Transverse (Sectional or Ledger) Bracing : Diagonal braces installed in the plane of the shorter dimension (width) of the scaffold. Zig-Zag (Dog-leg) Bracing : Diagonal braces placed end-to-end and that alternate back and forth.
What is scaffolding and its parts?
Scaffolding Parts or Components
Ledgers: Flat horizontal tubes that join between the standards. Ledgers connect multiple bays. Ledgers decide the height of the working platform. Transom or Bearer: Transoms are used to support standards and they are at the right angles to the ledgers. Transoms define the bay width.
What are the 3 types of scaffolds?
Yet, despite the many types of scaffolding, there are only three main categories: suspended, support, and aerial.
What are ledgers in scaffolding?
Ledgers are 48mm diameter tubes with a cast wedge fixing device at each end. They are positioned horizontally between two vertical scaffold standards to give the length of the scaffold bay, at platform level. They may also be fitted as a handrail.
What is a scaffolding ladder?
ladder scaffold means a scaffold with a working platform which is supported directly or by means of a crutch or bracket on a rung or rungs of a ladder; Sample 1. Sample 2. Sample 3. ladder scaffold means a scaffold with a working platform which is supported.
What is bricklayer scaffold?
Brick layers scaffolding or Single scaffolding. In this type of scaffolding, a series of vertical members made of bamboo or timber (named as Standards), are firmly fixed into the ground in a row parallel to the building wall. The distance in between two standards is generally kept within 2.4 to 3 m.
What is transverse bracing?
n (Anatomy) either of the projections that arise from either side of a vertebra and provide articulation for the ribs. transverse wave. n a wave, such as an electromagnetic wave, that is propagated in a direction perpendicular to the direction of displacement of the transmitting field or medium.
What is a suspended scaffold?
A suspended scaffold incorporates a suspended platform capable of being raised or lowered when in use. Other terms often used are ‘suspended cradle’ and ‘swing-stage’ scaffold. They are typically prefabricated modular units (see Figure 1) or permanently fabricated units although they can be assembled from scaffolding.
What is a bay in scaffolding?
Bay in relation to scaffolds, means that portion of the scaffold between horizontal or vertical supports whether standards or supports from which the portion is suspended, which are adjacent longitudinally; Sample 1.
Why is it called Baker scaffold?
Narrow frame scaffolds are also called Baker for Perry scaffolding. Because of their small size, portability and configuration options, they can be used in many different construction and work applications. They function the same as a platform ladder and they are safer and cost less.
What are the three types of scaffolds OSHA?
Workers who use scaffolds can be divided into three groups:
- Suspended Scaffolds.
- Supported Scaffolds.
- Aerial Lifts.
What do aerial scaffolds include?
Types include:
- Extendable boom platforms,
- Aerial ladders,
- Articulating (jointed) boom platforms,
- Vertical towers, and.
- Any combination of the above.
Is also known as masons scaffold?
Single Scaffolding
Single scaffolding is generally used for brick masonry and is also called as brick layer’s scaffolding. Single scaffolding consists of standards, ledgers, putlogs etc., which is parallel to the wall at a distance of about 1.2 m.
What are the four main types of scaffolds?
Types of scaffolding
- Single scaffolding. Single scaffolding stands parallel to a wall of a structure by using vertical supports called standards.
- Double scaffolding.
- Cantilever scaffolding.
- Suspended scaffolding.
- Trestle scaffolding.
- Steel scaffolding.
- Patented scaffolding.
- Wooden and bamboo scaffolding.
What is scaffold transom?
The transom, a horizontal cross-section load-bearing component which holds the batten, board, or decking unit.Batten or board decking component used to make the working platform. Coupler, a fitting used to join components together. Scaffold tie, used to tie in the scaffold to structures.
What is difference between ledger and transom?
Ledgers – horizontal tubes tying the structure together longitudinally, usually running parallel to the face of the building. Transoms – short horizontal tubes spanning across ledgers normally at right angles (90°) to the face of the building. They may also be used to support a working platform.
What is the most commonly used type of scaffold?
Supported Scaffolding
Supported Scaffolding
This is the most commonly used form of scaffolding and is the type that you will see being used in construction work and on most other forms of work where elevation is required.
What is a jack scaffold?
A ladder jack scaffold is a system designed to perform activities, such as: installing building exteriors, trim, and finishes.Triangle-shaped brackets called “ladder jacks” are attached to portable ladders, which are used on each side of a ladder jack scaffold to form a means of support for a platform.
What are the 3 types of ladders?
Ladders come in a range of styles to suit the different jobs they can be used for:
- Single Pole Ladders (maximum length 9 metres)
- Extension Ladders (maximum length 15 metres)
- Step Ladders (maximum height 6.1 metres)
- Dual Purpose Ladders (stepladder hinged to provide an extension)
- Platform (podium) Ladders.
