What is a scaffold in teaching?
Instructional scaffolding is a process through which a teacher adds supports for students in order to enhance learning and aid in the mastery of tasks.
The teacher does this by systematically building on students’ experiences and knowledge as they are learning new skills..
What are the 3 load ratings of scaffolds?
OHSA designates three different categories for load bearing calculations on scaffold boards. They are: Light Duty – 25 pounds per square foot. Medium Duty – 50 pounds per square foot.
What are the 3 types of scaffolds?
There are three basic types of scaffolds: Supported scaffolds, which consist of one or more platforms supported by rigid, load-bearing members, such as poles, legs, frames, outriggers, etc. Suspended scaffolds, which are one or more platforms suspended by ropes or other nonrigid, overhead support.
What is the rated load capacity for a medium duty scaffold?
50 pounds per square footRated Load CapacityRated Load Capacity of ScaffoldIntended Load Should BeLight-Duty “standard”25 pounds per square foot (applied uniformly)Medium-Duty “brick masons”50 pounds per square foot (applied uniformly)Heavy-Duty “stone-setters”75 pounds per square foot (applied uniformly)
What type of scaffolding holds more weight?
Weight Capacity These types of scaffolds are best used when weight is spread out along the platform. A light-duty scaffold can hold about 25 pounds per square foot, a medium-duty scaffold can carry 50 pounds per square foot, and a heavy-duty one will hold 75 pounds per square foot.
What is medium duty scaffold?
Medium Duty Scaffolding refers to a Safe Working Load (SWL) of 450Kg per bay or tower. This equates to four average male workers with tools and equipment.
How is SWL of scaffold calculated?
– D = Dead Load: This is the weight of the working platform and the scaffold components. When all the variables in the formulae is obtained, fixing the values in, we can calculate the SWL of any scaffold. HSEWatch is an all-encompassing Health and Safety platform.
How high can you go with scaffolding?
Scaffold tower can be erected in all shapes and sizes. The standard dimensions are 5 foot and 7 foot long. Reaching 5 foot high all the way up to 30 feet tall.
How do you stabilize scaffolding?
Once the scaffolding is assembled and in place, double-check that it’s level and resting securely on all four base plates or casters. If it rocks, readjust one of the screws to stabilize the scaffolding. Use the built-in ladders to climb the scaffolding. Don’t climb on the cross braces.
What size is standard scaffolding?
The scaffolding width is determined by the width of the boards, the minimum width allowed is 600 mm but a more typical four-board scaffold would be 870 mm wide from standard to standard. More heavy-duty scaffolding can require 5, 6 or even up to 8 boards width.
