Acrow Props - Selecting The appropriate Prop On your Project

Posted

What on earth is An Acrow Prop?

Acrow props can be seen on many construction sites and so are employed to support a structure or transfer a large quanity. Construction props can be accustomed to support concrete form work while the concrete is curing or even support a roof or overhead structure while removing, replacing or repairing a wall or some other supporting structure. They may be an easy task to position and are generally fully adjustable with in the peak array of the prop.

Acrow props

Acrow props contain two circular steel tubes, an inner tube using a top plate that slides down and up freely in a outer tube which is attached to the base plate. The inner tube has holes down its length to enable you to quickly extend the inner tube just to below the specified height and insert a steel pin to lock in that length. To supply the prop towards the correct height the top of the outer tube is threaded along with a collar, and that is much like a nut for a bolt, registers and props up steel pin. So by rotating the collar and moving up it extends the inner prop. This lets you reach the exact height required.

With regards to using Acrow Props on the project you then have a few different options to choose from. Acrow Props come in 5 various sizes originating from a No.0 to a No.4, how do you pick a qualified prop on your project?

Start With Your Propping Height

Well step one is usually to go through the height or distance that you will be seeking to prop. Avoid the use of props which might be quite short by causing on the gap with timber as well as other packer and use the correct length prop for the position. Similarly, if the propping distance is to the limit of your fully collapsed prop it may be best to decide on the following size to ensure that there may be enough adjustment from the prop when there is a small variation on site.

No.4 -- 3100 - 4900 mm ( or 10.17 - 16.07 feet)

Estimate The Load You will want to Support.

The 2nd step is usually to have a look at what load the prop needs to support. You simply must consult your Engineer and other responsible persons regarding the weight of your overhead structure just for them to evaluate which loads need to be supported. The spot that the load is above the proportions of a single prop you can utilize multiple props to enhance the supported load in the given area.

The next table is going to be used as a general guide only as specifications will change with assorted suppliers. Please check using 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 certain that wherever you choose a construction prop which the structure at their base along with the head of your prop are solid and sufficiently strong enough to aid the load. When there is any doubt it would have been a good plan to spread the impact on the prop using a spreader beam or plate.
