#construction #m20 #concrete #information #influencer #viralvideo #yt --- What is a Wall Lantern in Construction? A wall lantern is a horizontal RCC (Reinforced Cement Concrete) band provided in the masonry wall. It is used to tie the entire wall structurally and is especially useful in seismic areas to prevent cracks and improve the building's strength. It is also commonly referred to as a lintel band, wall band, or tie beam at wall level. --- Purpose of Wall Lantern Provides structural reinforcement to walls Prevents cracks in long or high walls Ties all walls together to improve earthquake resistance Distributes loads evenly over door and window openings Reduces the chance of wall failure due to lateral forces --- Where is the Wall Lantern Used? Commonly placed at lintel level, which is just above doors and windows Sometimes provided at plinth level and roof level too Useful in both brick and block masonry walls Common in load-bearing wall construction --- Wall Lantern Thickness Thickness is generally 4 inches (100 mm) or 6 inches (150 mm), depending on wall type Width is equal to the wall thickness, such as 4 inch, 6 inch, or 9 inch --- Concrete Mix Ratio The concrete mix used depends on the structural requirement. Generally, the following grades are used: M15 grade concrete with a mix ratio of 1:2:4 (cement : sand : aggregate) M20 grade concrete with a mix ratio of 1:1.5:3 M20 is preferred for stronger and longer spans, especially in earthquake zones --- Steel Reinforcement Details Main Bars: Two or more 10 mm or 12 mm diameter steel bars In long spans, use three or four main bars for added strength Stirrups: 6 mm or 8 mm diameter stirrups (rings) Spacing is 150 mm center to center Rings should be closed and properly tied to the main bars --- Formwork for Wall Lantern Use wooden or steel shuttering Align it properly with the wall to prevent bulging or leakage Apply shuttering oil for easy removal after setting --- Concrete Pouring Process Mix concrete manually or with a mixer Pour evenly to avoid segregation Use a vibrator to compact the concrete if available Tap manually with rods if vibrator is not available Level the top surface smoothly with a trowel --- Curing of Wall Lantern Start curing after 24 hours of casting Keep it moist for at least 7 to 14 days to gain strength Use jute bags, cloth, or water sprinkling --- Key Points to Note Maintain a clear cover of 15 to 20 mm for steel bars Provide proper overlap of steel bars where necessary (50 times the bar diameter) Align the band continuously through all walls Ensure no gaps or honeycombs #homedecor #viralshort #youtube #viral #yt #interiordesign #howto #howtomakemoneyonline #howtoviralshortvideo #information #knowledge #howto #howtomake #diy #proeprty #realestate #reinforcement #constructionsite #concreteslab #viralshort #trending #home
