 Steel ruler should be matched with the steel ruler for steel structure manufacture, to obtain the certificate of legal measures.
 
    预埋件的定位安装 Location and installation of pre-buried parts
1)由于钢柱吊装的要求，预埋件的安装是在钢结构安装之前，即在土建施工过程中就要开始埋设。因此，在土建施工过程中，由控制网对预埋件进行定位。
 Due to the requirements of steel column hoisting, the pre-buried parts should be installed before steel structure installation, which means the pre-bury should start during civil construction. Thus, the pre-buried parts will be positioned by control net during the civil construction.
 
2)根据布设的施工方格网，用钢板制作成的定位框，在浇混凝土之前，将预埋件牢靠地固定在混凝土结构主筋上。
 According to arranged construction square grid, the pre-buried parts should be firmly fixed on the main bar of concrete structure with localization frame manufactured by steel plates.
 
    前期预埋： Pre-bury at early stage:
1)钢结构安装分前期预埋与后期集中安装二大工程内容。
 Steel structure installation includes pre-bury at early stage and centralized installation at late stage.

支承面、预埋地脚螺栓（锚栓）的允许偏差表
Table of Allowable Deviations of Supporting Surface and Pre-buried stone bolt (Anchor Bolt)
 
    吊装机械 Hoisting machinery
1) 根据此工程钢架的特点，故在钢结构吊装中可采用二台25T汽车吊，其他次构件使用16T汽车吊单机悬吊。因为汽车吊具有移动灵活，快速便捷等优点，这样地构件的卸货、倒运等均可带来很大方便，可以大大加快施工进度。
 According to the features of steel frame of the construction, so two 25T mobile cranes will be used in steel structure hoisting and other secondary members will be hoisted by 16T mobile cranes. Because mobile crane is featured with mobility and high speed, it is very convenient for unloading and transporting structural members and increases the construction progress greatly.
 
    吊装顺序： Hoisting sequence:
构件吊装顺序为：钢柱——钢梁（吊车梁）——屋面檩条——屋面支撑系统——其余檩条及墙架。 Hoisting sequence of structural members: steel column —— steel beam (crane beam) —— roof purline —— roof supporting system —— other purlines and wall frame
 
    钢柱的吊装 Hoisting steel column
1)吊装前，根据土建工程基础平面，对基础的轴线以及基础的水准标高进行校核。发现问题，应会同建设单位及设计单位等有关协商解决。
 Before hoisting, foundation axis and level elevation should be checked according to foundation plane of civil construction. Once finding out any problem, it should be consulted with construction and design units.
 
2)基础验收合格后，即开始钢柱的吊装。钢柱应顺序放置于基础边缘，起吊时采用旋转吊装法或者滑行吊装法，注意钢丝绳结钢柱的绑扎点，避免钢丝绳滑动。
 As soon as the foundation acceptance is qualified, hoisting steel column starts. Steel column should be placed at the edge of the foundation in the order, rotatary hoisting method or coasting hoisting method should be used during lift, colligation points of steel cable node on steel column should be attached with attention to avoid slippage of steel cable.
 
3)钢柱经过初步校核后，待垂直度偏差控制在20mm以内方可使起重机脱钩。钢柱的垂直度用经纬仪检验，如有偏差，重新进行校正。在校正过程中，随时观察柱底部和标高控制块之间是否脱空，以防校正过程中造成水平标高的误差。起重机脱钩后，钢柱宜用缆绳临时固定，等到屋架梁吊装完毕后，再次校核柱的垂直度，做好记录。
Crane should only unhook when the verticality deviation is within 20mm, after the initial examination of steel column. The verticality of steel column should be examined with theodolite, if finding deviation, the adjustment must be performed again. During the adjustment, the void between column bottom and control block of elevation should be momentarily observed, to prevent causing deviation of level elevation during adjustment. After the crane unhooks, steel column should be temporarily fixed with cable, the verticality of column should be examined again and well recorded after hoisting roof frame and beam.
 
    吊车梁吊装 Hoisting crane beam
钢柱吊装就位校正固定后，检查牛腿上平面水平标高是否符合允差范围，若超差，检查原因，以最高点为基准做调整垫板，并划牛腿平面十字中心线，吊车梁依十字线吊装就位固定，然后在吊车梁上平面架设一台水准仪，检查各点水平标高，并做好记录，以便安装吊车钢轨时调整其水平度。
 Level elevation of upper plane of corbel should be examined whether matching the allowable deviation range, after steel column hoisting is in position and fixed, if it is above the deviation range, checking reasons. The maximum point should be used as the reference for making riser block, and the cross centre line of corbel plane should be made, the crane beam should be hoisted and fixed according to cross line, the a leveling instrument should be set up on the crane beam. Level elevation of each point should be checked and well recorded, to adjust its levelness during installing crane rail.
 
    屋架梁的吊装 Hoisting roof frame and beam
1）吊装前根据《钢结构工程施工及验收规范》GB50205-2001有关规定仔细检查构件的外型尺寸和几何尺寸。
 Before hoisting, external and physical dimensions of structural members should be carefully examined according to Code for construction and acceptance of steel structure engineering GB50205-2001.
 
2）屋架梁根据实际情况，在地面先将一跨屋架梁组装后再进行吊装，这样既可提高吊装效率，也有利于保证吊装稳定性。
 According to practical, roof frame and beam should be installed on the ground at first before hoisting. With this measure, not only the hoisting efficiency increases, but also the stability of hoisting is guaranteed.
 
3）屋架梁根据实际情况，在地面先将一跨屋架梁组装后再进行吊装，这样既可提高吊装效率，也有利于保证吊装稳定性。
 According to practicals, roof frame and beam should be installed on the ground at first before hoisting. With this measure, not only the hoisting efficiency increases, but also the stability of hoisting is guaranteed.
 
4）屋架梁在起吊前，须将钢梁洗刷干净，以减少高空作业，加快施工进度。
 Before hoisting roof frame and beam, the steel beam must be washed to reduce high-attitude operation and increase construction progress.
 
5）屋架梁吊装因为采用悬空吊装，为使起吊后不致发生摇摆，和其他构件碰撞，起吊前在离支座的节点附近必须用缆风绳固定，分别由人员控制，随吊随放松，以保持屋架梁的稳定性，吊装就位后，吊车吊钩松开前，第一榀梁必须梁中部两边用钢绳风缆固定，钢梁线性直线度检查采用拉线测量法或经伟仪，检查钢绳风缆固定牢固后方可松钩；第二榀梁屋架吊装后，用檩条及支撑固定后，才可以松开吊钩，注意屋架梁的扭曲情况；第三榀梁吊装以此类推。
To avoid swing or collision with other structural members, roof frame and beam hoisting uses suspended hoisting. Before hoisting, tighten the string connected strand with hawser cable which is respectively controlled by worker and released at assembly, to ensure the stability of roof frame and beam. Two points near the middle of the first beam must be fixed with steel wind-cable before hoisting is in position and after the crane unhooks. The linear straightness of steel beam should be examined by the tagline survey method or theodolite, the crane can only unhook after examining the steel wind-cable is fixed and tight. After hoisting the second roof beam and frame, it should be supported and fixed with purline before unhooking, pay attention to the distortion of roof frame and beam. The third beam is hoisted by the same way, and so on.

    楼面钢框架梁的吊装 Hoisting steel frame beam of floor
将具有结构类型大致相同的情况归纳为标准节框架。
 Situations with similar structure types should be generalized as standard frame.
 
1）每节框架吊装时，必须先组成整体框架，暂不校正柱子垂直度，间距偏差，只以能满足楼层梁安装、螺栓能进孔为限（当然对明显偏差大的情况还得进行校正处理），尽量避免单柱长时间处于悬离状态，使框架尽早形成，并增加吊装阶段的稳定度。
 By hoisting every frame, the entire frame should be assembled firstly without adjusting the verticality and spacing torlance of column, which is enough to meet limits of floor beam installation and bolt installation (but if the deviation is oberviously above the range, adjustment should be also performed). To quickly form the frame and increase the stability at hoisting stage, the single column should avoid suspension in long time as much as possible.
 
2）总的吊装顺序应先吊框架柱，后吊框架梁与支撑，先吊主要构件，后吊次要构件。
The general hoisting sequence should be from frame column to beam and support of frame, from main members to secondary members.
 
3）每节框架在安装高强螺栓和电焊施工时，必须严格执行先顶层梁，其次底层梁，最后为中间层梁的操作顺序，使框架的安装质量得以能相对的控制，每节框架梁焊接时，应先分析框架柱子的垂直度偏差情况，有目的地选择偏差较大柱子部位的梁先进行焊接，以使焊接后产生的收缩变形，有助于减少柱子的垂直度偏差。
 By installing high strength bolts and performing electric welding, the work must be strictly carried out from top beam to bottom beam, and the beam of middle layer should be the last, to control the installation quality of frame. By welding every frame, analysis on deviation of verticality should be performed at first, column parts with large deviation should be welded firstly, so that these parts produce deformation after welding to reduce the vertical deviation of the column.
 
4）每节框架内的钢楼梯及金属压型板，应及时随框架吊装进展而进行安装，这样既可解决局部垂直登高和水平通道问题，又可起到安全隔离层的作用。
 Steel stair and metal profiled sheet in every frame should be timely installed with the progress of frame installation. This measure can not only solve problems of partial vertical upraise and horizontal channel, but also make the security isolation effective.
 
5)同一连接面上的螺栓，应由接缝中部向两端顺序进行紧固，两个连接构件的紧固顺序是：先主要构件，后次要构件。
 Bolts on the same junction surface should be tightened from the middle to both ends of seam. The tightening sequence of two connecting members is: from main members to secondary members.
 
6)当天安装的螺栓，应在当天终拧完毕，其外露丝扣不得少于2扣。
 Bolts installation should be completed on the installation day and their screw threads should never be less than 2 threads.
 
7)所有零件安装前必须除污清理，避免吊装后无法清洗或难以清洗。
Dirt of all parts must be cleaned, which is difficult to clean after hoisting.
 
    檩条安装 Purline installation
屋面檩条由吊车成捆送至屋面，人工分散，安装就位，檩条安装过程中需掌握两个原则：一是安装，因为屋架距地面有数米的高度，需注意带好安全带及安全帽，严防任何事故的发生；二是质量，安装中首先精确纠正第二榀钢架位置，并加以固定，用葫芦纠正其它各榀位置，然后安装檩条隅撑及拉杆，循序向前推进，檩条安装完毕后，通过调节拉杆螺栓来控制檩条间距和直线度。
 Bundled roof purline should be transported by crane to roof and distributed for installation by manual work. Two principles should be adhered: the first is installation, because roof frame is several meters high above the ground, working staff should fasten safe belts and wear safe helms to prevent any accidents; the second is quality, position of the second steel frame should be accurately adjusted above all and fixed, positions of other frames should be adjusted by calabashes, then knee brace and tension rod of purline should be installed step by step, after completing the installation, spacing and straightness of purline should be controlled by adjusting stay bolts.
 
    钢结构表面涂装 External coating of steel structure
1)施工环境：本防腐系统施工环境要求在5度----38度，相对湿度不大于85%，同时在雨、雾、雪和较大量灰尘条件下，禁止在室外施工。
 Construction environment: environmental requirements of the preservative system are: temperature between 5 – 38℃, relative humidity is below 85%, outdoor construction is forbidden under rain, fog, snow and considerable amount of dust.
 
2)施工准备：在涂装前，先检查钢材表面处理是否达到防锈等级的要求，是否仍有返锈或重新污染的现象，否则应重新处理，同时除锈后要求在12小时以内即喷底漆。对于不需涂装和禁止涂装部位，应事先用胶纸带遮盖起来以免上漆。
 Preparation: whether the superficial treatment of steel achieved rating requirements, whether corrosion or pollution is found, whether treatment should be performed again, all above problems should be checked before coating, meanwhile, primer should be made within 12 hours after derusting. For parts which are not required or forbidden to coat, they should be covered with tape in advance, to avoid painting.
 
    屋面、墙面板制作及吊安装措施
Measures for manufacturing and hoisting  roof and wall board
1)    屋面板制作及吊装 Manufacture and installation of roof board
屋面板采用组装式彩板专用吊架组装而成，长45米，吊架至吊钩用6道钢丝绳，吊架与屋面板固定采用8道1.5T/条丝绵纶吊带紧带器固定，两端用风缆稳住吊件，吊至屋面。屋面板送至屋顶后，应立即分散就位固定，当天吊多少安装多少，不允许隔夜安装，以防大风吹落。
Roof board should be assembled by special suspension bracket for assembled color board and then hoisted to roof, the bracket is 45 meters long and has 6 wire ropes from the bracket to hook, the bracket and roof are fixed by hoisting belt tightener with 8 1.5T/piece floss aramid and both ends are held by wind-cable. As soon as the roof boards arrive the roof, they should be immediately distributed for fixture in position, all hoisted boards should be installed on the same day without overnight installation, to prevent from falling by strong wind.
 
2)    屋面板安装 Roof installation
(1)按设计要求和彩板安装规范进行安装，特别要注意第一块板必须垂直跨距轴线及板与板之间的搭接和位置，安装顺序，注意固定螺栓拧紧程序，防止密封垫圈而影响效果，尤其是板与板之间接缝的安装，切实做好防渗防漏工作。
 Installation should observe design requirements and color plate installation code, the first board must be vertically across axis, as well as related joint and position between boards, which should be pay special attention. In installation sequence, antiseepage and leakage control should be well performed, which means tightening procedures of fixing bolts should be notices to prevent from detrimental effect of unsealed joint washers, especially in seam installation between boards.
 
(2)收边：对于本公司生产的所有屋面外板，都可以用专用工具对板端进行收边，靠近屋脊处的板端，可以用上撬工具将位于钢板终端肋条之间的底盘向上折，形成止水端，止水端用于所有坡度低于25度的屋面板的上端，以保证在泛水板或盖板下方由风吹入的水不会流入建筑物中，折边操作可以在钢板定位之前实施，也可在钢板安装之后实施，但后一种方法要在钢板的项端留有约50mm的间隙，便于上撬工具的操作，当屋面坡度小于10度时，应将钢板下端的底盘端部向下弯曲，这一过程可用下撬工具来实现，形成滴水线，这样可保证雨水顺着钢板终端被排出，并且不会因毛细或风力作用回流到平底盘的下边，向下折边的操作必须在屋面板被固定以后才能进行，否则这项操作将会受到障碍。
 Trims: all external roof boards manufactured by our company could use special tool to trim their ends. For ends close to ridge, the base plate locating between end ribs of steel board could be bended upward by lifting tool to form water stop end, the water stop end will be used at the upper end of all roof boards of which the slope is below 25 degrees, to prevent water blown by wind under flashing or cover board from flowing in the building. Hem operation could be performed before positioning steel plate or after installing the plate, but with the later method, the plate should be reserved 50mm gap on the top of the plate, which makes the operation of lifting tool convenient. When the roof slope is less than 10 degrees, the base plate of lower end of steel plate should be bended downward, this process could be realized by lifting tool and forms water drip, which can ensure the rain could be discharged along steel plate end without refluxing to underneath of flat plate by wicking or wind action. The downward hem must be operated after fixing the roof boards, otherwise, this operation will meet difficulties.
 
3)    墙面板轧制及安装 Rolling and installing wall board
墙面板轧制：墙面板在工厂加工后直接运至工地，采用单节9米彩板吊架卸车，卸至所用位置附近。
 Rolling wall board: wall board will be directly transported to the site after completing process in the factory. Boards will be unloaded by single section 9m suspension bracket for color board and placed near the working site.
 
(1)   安装步骤：用墙面安装专用管架架设于墙面板安装位置，管架单面与墙面檩条分段固定，安装人员约每三档檩条一个就位于管架上，将压型钢板平放在平整干净的地面上，墙面板顶部打一Ф6mm吊板工艺孔，由地面人员将沿墙方向放置，由管架上部人员用绳向上拉，地面人员向上送，安放至安装位置，对准位置，然后用自攻螺丝固定，第二块板准确地搭接在第一块板上，并与第一块压紧再用自攻螺丝固定，随时检查压型板的平行度和垂直度，发现不垂直时，应及时调整。
 Installation steps: special pipe frame for wall surface installation should be built up on the installation position, single side of pipe frame and wall surface purline should be fixed in each section, installation staff sands on the frame with the spacing of about three purlines and the profiled steel plates should be placed on flat and clean ground. A Ф6mm fabrication hole of hanger plate should be drilled on the top of wall surface plate and placed along the wall direction by ground staff, the plate will be lifted by staff on frame top and supported by ground staff till to the installation position, after aligning the position, the plate should be fixed with self-tapping screws; the second plate should accurately lapped on the first and fixed with self-tapping screws after tightly compressing with the first one. The parallism and verticality of the profiled plate should be checked at any time, if it is not vertical, adjustment should be performed timely.
 
(2)   竖向搭接：一般当压型板作墙面板时，长度足够覆盖整个墙面，无需进行竖向搭接，但有些特殊结构需要进行竖向搭接。压型钢板的竖向搭接方法与屋面板的纵向搭接相似，安装时上面的板搭接在外，下面的板搭在里面，搭接长度为150mm。
Vertical lap: in general, when the profiled plate is used as wall surface board, its length could cover the whole wall surface so that it is unnecessary to perform vertical lap. By installation, the upper board is lapped outside and the lower board is inside, the lap length is 150mm.
 
4)    泛水板及收边板的安装 Flashing and trim plates installation
泛水板和收边板的安装是整个围护系统安装的重要部分，直接影响整个工程的质量和效果，所以应该特别重视。
 Flashing and trim plates installation is an important part in the whole bounding system installation, which can influence quality and effectiveness of the entire construction, thus special attention should be attached.
 
(1)   纵向泛水板和盖板 Longitudinal flashing and cover plates
纵向泛水板和盖板应在屋面板平底盘和波谷处有一向下弯的翻边，下弯的深度同钢板外形相应，泛水板安装好以后，一般与屋面板的波峰用自攻螺钉进行固定，纵向泛水板之间的搭接可参照纵向压型板的搭接形式，搭接长度为200mm，沿顺坡方向靠近坡顶的泛水板搭接在上面，在搭接处涂上密封胶。
 Longitudinal flashing and cover plates should contain downward bending roll flanging edge on flat plate and wave through of roof board, the depth of downward bending should correspond to the shape of steel plate. In general, flashing plate should be fixed to wave peak of roof plate by self-tapping screws, lap between longitudinal flashing plates could refer to lapping form of longitudinal profiled plates, with 200mm lapping length, and could be lapped on the flashing plate lap joint near slope top along the slope direction, the lap joint should be sealed with sealant.
 
(2)   横向泛水板和盖板 Transverse flashing and cover plates
用于屋面的横向泛水板和盖板，沿下方边线有一加工时的裂口，为保证防雨，可使切割裂口使其与波纹相配，也可稍作修改，使其嵌入沟槽之中，对小坡度屋面，最好将裂口切开贴紧波纹，带肋条钢板的横向泛水板和收边板，需要沿着低边缘处开槽或向下弯折，以便与钢板外形相配，这样可防止由风带来的水渗透到泛水板之下。
