Without proper load calculations you can end up with sagging floors and cracked walls.
This is a great example of loli columns spaced properly to create the correct span for that sized beam. Loli columns are one of the accepted methods for structural support point loads.
This is an improperly built concrete block column. Proper mortar joints and proper placement of the block are necessary to create the proper bearing capacity. This photo shows neither.
This is what is referred to as a screw jack. It can be turned to expand or contract in length to make it higher or lower. It is typically used to brace failing or sagging beams. It is not code compliant and will not pass any structural inspection. It is what we refer to as a band aid or patch job.
This is a properly built concrete block column pier which has the same purpose as a loli column.
This is an example of a properly sized beam. It is a triple 2x10 girder and the span is 10’0” from concrete block pilaster to concrete block pier.
This is an example of a beam bearing on a pilaster.
This is an example of a pier footing that is formed and has steel rebar in it. The concrete gets poured in the form to create a surface for the loli column or concrete block pier to bare on. Concrete is best used for compressive strength (it does not compress) and steel rebar is best used for tensile strength ( the resistance of a material to breaking under tension ). The combination of steel and concrete being used together changed the way buildings are designed and paved the way for the skyscraper and the long span bridge.
This is an example of an improperly sized beam. Beams are calculated based on their span (how long they are between the point loads they are sitting on) and their size (2x6, 2x8 etc). When beams are improperly sized, they can result in sagging floors and cracked walls. From this photo, you can see how the beam is sagging on both sides of the column. To correct this issue, Thunder Road Masonry will install more loli columns, concrete piers or a bigger beam.
This is an example of footing forms for an addition to an existing house.
This is an example of completed concrete footings for an entire new house after the concrete is poured.
