Acrow Props - How to pick The ideal Prop To your Project
Acrow props is visible on many construction sites and are also helpful to support a structure or transfer an order. Construction props are usually helpful to support concrete form work as the concrete is curing or even to support a roof or overhead structure while removing, replacing or repairing a wall or any other supporting structure. They're simple to position and so are fully adjustable within the height selection of the prop.
Acrow props contain two circular steel tubes, an inner tube using a top plate that slides vertical freely in the outer tube which can be connected to the base plate. The inner tube has holes down its length so that you can quickly extend the inner tube to just below the actual required height and insert a steel pin to freeze that length. To give the prop to the correct height the top outer tube is threaded including a collar, which happens to be similar to a nut using a bolt, answers and supports the steel pin. So by rotating the collar and moving up it extends the inner prop. This enables you to have the exact height required.
When it comes to using Acrow Props for your project you have a variety of options to decide on. Acrow Props can be found in 5 sizes from a No.0 to the No.4, how do we choose the right prop in your project?
Begin with Your Propping Height
Well step one is to look at the height or distance that you'll be planning to prop. Don't use props which can be short by looking into making inside the gap with timber or any other packer and also use the correct length prop to do the job. Similarly, if your propping distance is on the limit of your fully collapsed prop it may be best to pick another size right down to be sure that there exists enough adjustment inside prop if there's a slight variation on site.
The subsequent table shall be used to be a general guide only as specifications will be different with some other suppliers. Book with the supplier for his or her specific specification.
No.0 -- 1050 - 1830 mm ( or 3.44 - 6.00 feet)
No.1 -- 1600 - 2800 mm ( or 5.25 - 9.18 feet)
No.2 -- 1900 - 3400 mm ( or 6.23 - 11.15 feet)
No.3 -- 2170 - 3975 mm ( or 7.12 - 13.04 feet)
No.4 -- 3100 - 4900 mm ( or 10.17 - 16.07 feet)
Estimate The strain That you should Support.
Another step should be to examine what load the prop is needed to support. You will have to talk to your Engineer or another responsible persons regarding the weight of your overhead structure so they can evaluate which loads have to be supported. Where load is greater than the capability of a single prop you should use multiple props to raise the supported load inside a given area.
This table is usually to be used being a general guide only as specifications will be different with assorted suppliers. Book together with your supplier for specific specification.
No.0 -- 22 - 42 KN -- 2243 - 4282 kg ( or 4945 - 9442 lbs)
No.1 -- 12 - 34 KN -- 1223 - 3467 kg ( or 2697 - 7643 lbs)
No.2 -- 11 - 39 KN -- 1121 - 3976 kg ( or 2472 - 8767 lbs)
No.3 --- 7 - 35 KN --- 713 - 3569 kg ( or 1573 - 7868 lbs)
No.4 --- 7 - 20 KN --- 713 - 2039 kg ( or 1573 - 4496 lbs)
Make sure wherever you employ a construction prop how the structure at both the base as well as head with the prop are solid and sufficiently strong enough to support the specified load. Should there be any doubt then it would be a good plan to spread the impact with the prop using a spreader beam or plate.
Keep in mind that the best number of your props is essential for the safety and efficiency of this building site and should remain signed off by a suitably qualified engineer or another qualified person.
