Project Menu Project Menu. Using a masonry drill bit and drill or an angle grinder with diamond tipped blade, drill or cut out the mortar from the joint, making sure you remove all of it. Mark each of these points along your mortar line. Depending on what support method your using e. A solid concrete base should be more than adequate worth getting it checked though but if you are propping off of a timber floor and joists, these will need to be checked to ensure that they can take the weight. Many of these are not immediately obvious. With the prop placed, pull the inner tube up until it is the rough height needed and push the pin all the way through so that it comes out the other side. As above, measure and mark the exact positions where each of your needles need to go, in line with the spacing calculations you or your engineer arrived at. Even if you have never used one before it is likely that you have come across one. De Vigier quickly identified these problems and set about inventing a new propping system that was made of steel and could be height-adjusted, meaning that it was much safer and longer lasting and could be used over and over again in a variety of different situations.

In this project you will learn all about the Acrow prop and how it can be used on conjunction with timber needles or Strongboxes to support a acrow prop dimensions bearing wall while new openings are created or repair work is carried out.

If there is take it off and start again, it needs to be absolutely solid! One other aspect to consider is the base that you will be propping off of. Some of the most common are as follows:.

All project content written and produced by Mike Edwardsfounder of DIY Doctor and industry expert in building technology.

Put simply, an acrow prop is a temporary vertical support used in the construction industry to hold up load bearing objects, preventing them from colapsing while building or repair work is carried out below.

Move your prop so that it is next to the area to be supported so that you can judge how far to pull up the inner tube and where you need to insert the pin. The first task before positioning your props and any structural supports is to mark out the exact area that you will be removing for your new opening.

With your Acrow acrow prop dimensions in place and your wall now fully supported you can now safely go ahead and remove any bricks and blocks to form your opening. Despite this, there are some pointers you should beaware of:. As the Acrow prop does such a great job when it comes to the supporting of vertical loads, numerous attachments have been developed and can easily be added to provide additional supporting.

These latter designs can also be threaded and have a collar that allows them to be screwed up or down for further adjustment and ease.

As we have stated several times, if you are in any doubt about whether your supporting methods will be suitable, get them checked by a professional structural engineer or architect before starting! Once both are, tighten the collar to a decent hand tightness and then check that the needle itself is fully engaged with the underside of any brick or block faces.

Drill or cut away all of the mortar around each brick, one at a time and use a club hammer and bolster to knock the brick out. With your Acrow or Acrows in place, tighten the screw collar s to the point that they are hand tight.

Before the Acrow prop was invented around by Swiss-born William de Vigier, timber beams were traditionally used, with each beam having to be cut acrow prop dimensions the correct supporting height for each job.

As you can imagine, this lead to a huge amount of waste and cost, not to mention safety issues as timber by its very nature is particularly susceptible to both fire and damp. With the above in mind, we would always recommend a qualified structural engineer or architect carry out these calculations for you so that you know they are absolutley correct.

The single-piece outer tubes are much sturdier than their welded counterparts. Traditional style timber supports β€” Image courtesy of actionwallties.

When it comes to needles, this is a similar process, but instead of removing just the mortar, we will be removing the entire brick or block or even several, to provide enough space to insert the needle.

Now, move the prop in to place, pushing the blade into the mortar slot you created, right up until the handle body is touching the face of the wall.

The Different Parts of an Acrow Prop When it comes acrow prop dimensions the individual parts of an acrow prop, its real beauty lies in its simplicity. Acrow props being used to support lintel β€” Image courtesy of constructionphotography.

Also ensure they are manufactured to BS standards.

Originally, the props were constructed of pure steel and, although they far outlasted acrow prop dimensions traditional timber prop, they were still subject to rusting over time, especially if they were left exposed to the elements. If any is left, especially on the underside of the bricks or blocks that the Strongboy will be taking the weight on, then this could compromise its ability to hold weight correctly and cause it to fail.

In most cases, the depth of the mortar line will be thick enough to get the blade in, but if not then you will need to remove article source brick above. Where the Strongboy differs is that instead of having to run them through both wall skins, mortar can be removed from between brick courses and the front edge of the blade of the Strongboy can be pushed through the gap to provide teh vertical support.

Do your own calculations if you know how by all means, but always get them checked by a professional just to be sure. A design featuring numerous moving parts or complicated internals would almost certainly spell unreliability, especially when subjected to the rigours of a building site. It is also important to note that you should never over tighten the collar as this can cause damage to the Strongboy itself, the prop and even the brickwork it supposed to be supporting. Now measure and mark this measurement either side of each mark on your mortar joint so that you have a line the total width of your blade with the propping point dead in the centre. Once you have made your holes and can easily pass the needle through, work through the below steps to get this area supported before you move on and create any futher holes. We are also going to assume that you are cutting a new doorway opening in to a cavity wall, where bricks or blocks are no more than mm thick and the cavity is 50mm in width and that you are inserting a reinforced concrete lintel for your new support.
