Insert steel girder or camber - what must be considered?

If you have to break through a wall, either to use an extra door, or even to remove the wall altogether, you must pay attention to a few things. What is important, and how to proceed properly in wall breakthroughs, you will learn in this post.

Wearing walls

You can not break load bearing walls, not even to install a door. When working on a load-bearing wall, this is done only after a static inspection and in strict compliance with the requirements of the structural engineer.

Please also note that if you carry out such work yourself, you are liable for all errors and damages that may occur in the following. Those who do not have sufficient expertise, and who can not implement the requirements of the structural engineer professionally and exactly according to all applicable standards, should by no means approach such work.

In some cases, structural walls may also statically have a stiffening function for the exterior wall. In these cases, the structural engineer will usually forbid you to break the wall, or the work required will be very complicated.

Example: installing a lintel

If you want to install a lintel in a wall and use a steel beam, there is only one way to do it right. By way of example, we have described the correct order below. All possibly deviating specifications of the structural engineer (such as: additional interception of the ceiling, special supports) is of course essential to follow!

Install lintel and break through wall for one pass - the steps

  • Steel girder in required length
  • suitable mortar
  • Plastering material (also stretched wire for plastering the support)
  • suitable tools for breaking through the wall
  • Container for rubble

1. Intercept ceiling (if necessary)

Information on how and where to support is what the structural engineer does. This information always mandatory.

2. Lift the slot for the carrier

Where the carrier is to sit later, lift a sufficiently high slot in the wall. There must be enough room to gut the carrier. If you need to make supports, you must leave room for them.

3. Insert carrier

If no special supports or reinforcements are needed, you can insert the support (camber), fix with wedges and mortar. It is important that you use suitable mortar, which is also approved for this application and sufficiently stable. Wait for the mortar to set.

4. Make wall breakthrough

Taking into account the required support surface for the carrier make the wall breakthrough with suitable tools. Depending on the wall texture use the appropriate tools.

5. plastering

The plaster and the resulting soffit plaster. If necessary, the soffit must be compensated accordingly, so that it is straight.

Tips & Tricks

The best way to plaster a wearer is in our special article. Before doing so, think about whether or not you will immediately install a suitable lintel from the respective wall material (for example, sand-lime brick). Often this is much easier and for most building materials there are prefabricated parts in many different lengths.
