![]() ![]() Therefore, understanding and following these tables is not just good practice but often a legal requirement. Most jurisdictions require the use of LVL span tables for building projects. This table ensures that the load applied to the beams will not exceed their capacity, which in turn guarantees safety. Using an LVL span table can significantly reduce the risk of structural failure. The Importance of LVL Span Tables in Modern Construction Risk Mitigation Always be mindful of unit conversions when interpreting these tables, as a miscalculation can have severe consequences. The units used in LVL span tables may vary, depending on the source. Understanding these terms is critical for proper application in projects. Anatomy of an LVL Span Table Understanding the MetricsĪn LVL span table usually contains a variety of metrics such as span, load per linear foot, and deflection limits. These tables provide data on how much weight a particular LVL beam can bear, which is essential for preventing structural failures. The core purpose of LVL span tables is to ensure safety in construction. These tables provide architects, engineers, and builders with crucial information needed for safe and effective structural designs. What Are LVL Span Tables? Definition and PurposeĪn LVL span table is a technical document that specifies the weight capacities and spans of Laminated Veneer Lumber (LVL) beams. ![]() But what exactly is it? How do you read it? Why is it crucial for your projects? This article aims to demystify LVL span tables, making them more accessible and understandable, even if you’re not a seasoned professional. We’ve been providing professional grade tape measures for more 140 years in a range of scales, lengths and durable cases.If you’re involved in construction, architecture, or engineering, you’ve likely come across an LVL span table at some point. If you’re in the market for a new tape measure, turn to U.S. Always take care to pull or push your tape so that it’s taut to take advantage of the true zero feature. Thus, the metal piece will shift back to fill the gap. If you’re measuring the outside of a surface and hook your metal end on the edge, that metal piece will shift out and create a gap, so that you aren’t counting it in your measurement.Īnd if you need to measure the inside of a surface – like in a window frame, you want to count the thickness of the metal piece in your calculations. The metal tip is exactly 1/16 of an inch thick. This isn’t an error: it’s meant to provide you with accurate readings whether you’re measuring the inside or outside edge of a surface. The first inch of the tape is short by 1/16 of an inch. The metal tip at the end of your tape measure is a little bit loose for a reason. ![]() If you’re measuring something and don’t have a marking tool handy, you can use this serrated edge to make a mark by running it back and forth on whatever you’re measuring. THE SCRIBING TOOLĭid you ever notice that the bottom of the end hook of your measuring tape has a serrated edge? There’s a good reason for that. This way, if you’re measuring a flat surface and don’t have anyone to hold the other end of the tape, you just need to hammer in a nail or insert a screw and hook the end of the tape onto it to get a clear and accurate measurement. It’s there to grab onto the end of a nail or screw. On nearly every measuring tape, you’ll find a small slot on the end hook. Those diamond marks are there for builders who want to take advantage of the great strength of engineered I-beams by using fewer floor joists, with no loss of floor support. If you multiply these dimensions by 8, 6, 5, and 4, respectively, you’ll find each comes to 96”, the length of the plywood panels used for sub-flooring. ![]() Span tables for these beams provide ratings for spacings of 12”, 16”, 19 3/16”, and 24”. Because these beams can support more weight than their dimensional lumber counterpart, they often have different spacing requirements. The diamond marks on tape rule blades are for spacing these engineered floor joists in new construction. The black diamonds which appear every 19 3/16” on metal tape measures are for spacing I-beam “timbers.” Several wood-product manufacturers offer I-beam “timbers” as a substitute for solid lumber floor joists. This curve allows the blade to “stand out” while measuring, helping you read the measurement. Have you ever wondered why the blade on a tape measure is curved? The concave design helps keep the blade rigid when extended. Here are a few hidden features you will find within your tape measure. After all, a measuring tape is a simple device with a simple – although important – purpose: to measure things.īut there’s more to this tool than meets the eye. Are you getting the most out of your tape measure? ![]()
