1.2 普通紧固件连接工程施工工艺General Parts Construction Technology(1) 成品进场Refined Approach普通螺栓、铆钉、自攻螺钉、拉铆钉、射钉、锚钉(膨胀型和化学试剂型) 、地脚锚栓等坚固标准件及螺母、垫圈等等标准配件,其品种、规格、性能等符合现行国家产品标准和设计要求。Ordinary bolts, rivets, and self-drilling screws, rivets (expansion and chemical reagents), to such strong legs stud and nut standard parts, gaskets, etc. standard accessories, variety, specifications, and other products with existing national standards and design requirements.(2) 螺栓实物复验Complex and bolts kind experience普通螺栓作为永久性连接螺栓使用时,当设计有要求或对其质量有疑义时,应进行螺栓实物最小拉力载荷复验,其结果符合国家标准坚固件机械性能、螺栓、螺钉和螺柱(GB3098)的规定。Ordinary bolt connecting bolts as a permanent use, when the design requirements or questions about its quality should be carried out when the smallest lag bolts kind complex load testing and the results were consistent with national standardmechanical fasteners, bolts, screws and stud (GB3098).(3) 匹配及间距Matching and spacing连接薄钢板采用的自攻螺钉、拉铆钉、射钉等其尺寸与被连接钢板相匹配,其间距、边距等应符合设计要求。Thin plate connecting the self-drilling screws, rivets, such as its size and connecting plate by matching their distance, should comply with the design requirements and other fringe.(4) 螺栓坚固Solid bolts永久性普通螺栓紧固应牢固、可靠,外露丝扣不应少于 2 扣。Ordinary bolt should be firmly secured permanent, reliable, not less than two exposed screw deduction.(5) 外观质量Appearance Quality自攻钉、钢拉铆钉、射钉等与连接钢板应紧固密贴,外观排列整齐。Since the attack nails, rivets Steel, Steel Nailing should be secured so closely connected with stickers topology neat appearance.1.3 高强度螺栓工程施工工艺High Strength Bolt Construction Technology1.3.1 工艺流程Process作业准备选择螺栓及配套接头组装安装临时螺栓安装高强度螺栓高强度螺栓紧固检查验收.Ready to work Bolts and matching options Joint assembly Installing temporary bolts Installation of high strength bolts High strength bolts fastening Inspection and acceptance1.3.2 螺栓长度的选择Bolt length option扭剪型高强螺栓的长度为螺栓头根部至螺栓梅花卡头切口处的长度.选用螺栓的长度应为紧固连接板厚度加上一个螺母和一个垫圈的厚度,并且紧固的要露出不少于两扣螺纹的余长,一般按连接板厚加表 5-2 中的增加长度,并取 5的整倍数 .Torsional shear length of the high-strength bolts bolt-head bolts Plum card to the root of the length of the first incision. The length should be chosen for the fastening bolts interconnects thickness with a thickness of the nut and a washer and fastening the show at least two of the detained more than a l0ng thread, the general increase in table 5-2 by thick interconnects increase in the length of 5 mm and take the whole multiples.螺栓公称直径 Nominal diameter bolts 增加长度()Increase the lengthM16 25M20 30M22 35M24 401.3.3 接头组装Joint assembly连接处的钢板或型钢应平整,板边、孔边无毛刺;接头处有翘曲、变形必须进行校正,并防止损伤摩擦面,保证摩擦面紧贴。The link should be formed steel plate, plate edge, no burr hole; A joint warping, used to be calibrated to prevent injury and friction, the friction surface to ensure close.配件前检查摩擦机,试件的摩擦系数是否达到设计要求,浮锈用钢丝刷除掉,油污、油漆清除干净。Before friction machine parts inspection, the friction coefficient whether the specimen design requirements, floating steel brush to remove rust, oil, paint cleanse.板叠接触面间应平整,当接触有间隙时,应按规定处理,见表 5-3Stack contact area should be formed, when the contact gap, should be required to handle, as shown in table 5-3表 5-3间隙大小 Gap size 处理方法 Approach1以下 1 mm below 不作处理 Not processing3以下 3 mm below 将高出的侧磨成 1:10 斜面打磨方面应与受力方面垂直1:10 inclined to the higher side of the flowers into by the power and grinding should be vertical3以上 3 mm below 加垫板, 垫板两面摩擦面处理方法与构件相同Plus plate, plate friction dealt with two identical components1.3.4 安装临时螺栓Installing temporary bolts连接处采用临时螺栓固定,其螺栓个数为不远接头总数的 1/3 以上;并每个接头不少于两个,冲钉穿入数量不宜多于临时螺栓的 30%.组装时先用冲钉对准孔位 ,在适当位置插入临时螺栓,用扳手拧紧.不准用高强螺栓兼作临时螺栓,以防螺纹损伤.Connection temporary fixed bolts, the bolts more than one third of the total number of near joints; And not less than every two joints, nail penetration - the number should not be more than 30% of the provisional bolts. When first assembled at the nail holes, inserted in the appropriate place temporary bolts tightened with a spanner. Not allowed to use high-strength bolts served as interim bolts to prevent thread damage.1.3.5 安装高强螺栓Installation of high-strength bolts安装高强螺栓应自由穿入孔内,不得强行敲打. 扭剪型高强螺栓的垫圈安在螺母一侧 ,垫圈孔有倒角的一侧应和螺母接触,不得装反.Installation of high-strength bolts should be free penetration hole, not forced beating. Torsional shear-nut in high-strength bolts on the side of the gasket, washer and nut should side of the hole with a range of contacts, not anti-loaded.螺栓不能自由穿入时,不得用气割扩孔 ,要用绞刀绞孔,修孔时需使板层紧贴,以防铁屑进入板缝,绞孔后要用砂轮机清除孔边毛刺 ,并清除铁屑.Bolt free invasive, not use gas cutting reaming, with cutter knife hole, the holes need to make amendments lamellar close to prevent iron into joints and hole cutter wheel machine after use to remove the burr hole, and to remove iron.螺栓穿入方向宜一致,穿入高强螺栓用扳手紧固后 ,再卸下临时螺栓 ,以高强螺栓替换.不得在雨天安装高强螺栓,且摩擦面应处于干燥状态 .The same direction are advised to bolt invasive, invasive high-strength bolts secured with a spanner and then unloaded temporary bolts replaced with high-strength bolts. Not covered in the installation of high-strength
