Earlier than you may start putting in a pre-stressed lintel and bricking up, it’s good to be sure you have the proper supplies and instruments. You’ll need a pre-stressed lintel, a bricklayer’s trowel, a stage, a plumb bob, a tape measure, a hammer, and a few nails. As well as, you might also need to put on security glasses and gloves.
Upon getting gathered your supplies and ready your workspace, you may start putting in the pre-stressed lintel. First, it’s good to discover the middle of the opening the place you’ll be putting in the lintel. Then, it’s good to align the lintel with the middle of the opening. As soon as the lintel is in place, you may safe it with nails or bolts. Lastly, you may start bricking up the opening across the lintel. To do that, you will have to make use of a bricklayer’s trowel to use mortar to the bricks. As soon as the bricks are in place, you need to use a stage and plumb bob to verify they’re stage and plumb. After the bricks are dry, you may end the job by pointing the joints between the bricks.
Putting in a pre-stressed lintel and bricking up is a comparatively easy process that may be accomplished in just a few hours. Nevertheless, you will need to take your time and do the job accurately. If you don’t, you would find yourself with a cracked lintel or a wall that’s not stage. By following the directions on this article, you may be sure that your lintel is put in accurately and that your wall is structurally sound.
Getting ready the Lintel
Correct preparation of the lintel ensures its structural integrity and longevity. Observe these steps meticulously:
1. Select the Acceptable Lintel
Choose a pre-stressed concrete lintel that meets the precise load necessities and span distance of the opening. Think about components resembling imposed masses, bearing capability, and constructing codes. Seek the advice of with a professional engineer for complicated or high-load functions.
| Lintel Kind | Loading Capability | Span Distance |
|---|---|---|
| Single-Beam Lintel | Medium to Heavy | As much as 10 ft |
| Double-Beam Lintel | Heavy | Over 10 ft |
| Field Beam Lintel | Very Heavy | Customizable |
2. Place the Bearing Surfaces

7. Brick Up the Opening
As soon as the lintel is in place, you may brick up the opening. Observe these steps:
| Step | Directions |
|---|---|
| 1 | Lay a course of bricks on prime of the lintel. |
| 2 | Unfold a layer of mortar on the highest of the bricks. |
| 3 | Lay one other course of bricks on prime of the mortar. |
| 4 | Proceed laying bricks on this method till the opening is stuffed. |
| 5 | Level the joints between the bricks with mortar. |
Finalizing the Set up
8. Grouting and Pointing
After the brickwork has set, fill the joints between the bricks and the lintel with mortar. Use a pointing trowel to clean the mortar and create a neat end. To make sure a watertight seal, apply a water-proof sealant to the joints.
To guard the lintel from corrosion, apply a rust-resistant primer and paint. This can prolong the lifetime of the lintel and keep its structural integrity.
Lastly, take away any extra mortar from the encircling space and clear the lintel and brickwork. Examine the set up for any imperfections and make essential changes to make sure a professional-looking end.
