Foundation(Base) rebar arrangement  \n1) Foundation(base) work  \nIn foundation work, the lean concrete underneath the footing concrete, is very important.  \nWithout it, constuction site, on which a building will be raised up, it would not be  \nclean and stable disturbing construction work.  \nBe sure to make lean concrete working mat having at least 50mm of thickness. If F.L. of lean concrete is not fit, there are difficulty in fix S.L.  \n2) The height of spacer  \nBar spacer is used to maintain the arranged bar balanced.  \nWhen arranging the bars or flooring, stones and bricks can not be used to support them.  \nYou have to prepare spacer in advance because there are high possibility of unbalance when using stones or bricks to level the ground.  \n(in case of spacer height lean concrete top is 60mm)  \n\u003C Cover thickness of rebar >  \npart to not contact land  \npart to contact land  \nover 80mm of cover thickness in foundation rebar  \nover 50mm of cover thickness than pile head on base concrete  \nlean concrete  \n※The reason that the top of piles is embedded into foundation is that , in case of an earthquake , the pile causes bending fracture.  \nEspecially , when the ground is unstable , there should be specified directions on the drawings.(in case pile cover bending moment & compresssion or cover tension  \nproperly only)  \n6-D13(circular arrangement)  \nFillup CON’C (foundation CON’C)  \nHole closure PC or PHC  \nHOOP D13@150×4  \nPC Steel wire  \n2 times of pile diameter  \nPILE  \n3) Independent Foundation(Single Footing)  \nUsually in double footing and floating foundation , remained bar length is bent up and down to splice them together as depicted below.  \nHowever, the remaining parts of the bar can be cut off to reinforce the foundation.\u003CIn case of securing splice length> \u003CIn case of not securing splice length>  \n|  | when securing splice length\u003Cbr>|  |\n| --- | --- | --- |\n\nIn case of below splice length  \nstandard hook  \n4) Foundation(base) pillar tie hoop  \nThe main purpose of the tie hoop is to restrain the transverse load in order to relieve vertical load into pillar.  \nEven though foundation concrete has capacity to support the loads from the pillars, tie hoops help main bars be fixed at which they should be and it is important job.  \n\u003CBefore reinforcement> \u003CAfter reinforcement>  \n| slab~~ ~~\u003Cbr>\u003Cbr>|  |  |\n| --- | --- | --- |\n|  |  | |\n|  |  |  |\n\npillar  \nmain bar  \ntie hoop should be @300 distance per the drawing regulation,  \ntying  \nbottom tie hoop  \n~~ pi~~llar  \n※The tie hoops at the bottom hold the bars of the pillar in lean concrete and marking on the mould form is compared with drawing to ascertain the center of the pillars.  \n\u003CFoundation plate>  \n\n| | marking |\n| --- | --- |\n| The outer pillar must check main bar line. |  |\n\n5) Foundation(base) upper-support(Wooma) rebar  \n-Foundation thickness : below T=1,000mm for HD16, over T=1,000mm for HD19 space should be @1000-@1500","cbCaiqBX1AD3Hf8L","https://ap.wps.com/l/cbCaiqBX1AD3Hf8L","pdf",9910497,"English","# Foundation(Base) Rebar Arrangement\n## Foundation(base) work\n## The height of spacer\n## Independent Foundation (Single Footing)\n## Foundation(base) pillar tie hoop\n## Foundation(base) upper-support (Wooma) rebar","[{\"question\":\"Why is lean concrete under the footing concrete important in foundation work?\",\"answer\":\"Lean concrete beneath the footing concrete is essential to keep the construction site clean and stable, preventing disturbance during raising and construction work.\"},{\"question\":\"What is the purpose of using a spacer when arranging reinforcement bars?\",\"answer\":\"A bar spacer maintains the arranged bars in balance.
