具体实施方式
下面将结合附图对本发明中的具体实施例作作详细说明。
本发明以大型球面LED屏幕为例加以说明，但并不限于此，可以是各种大型的曲面LED屏幕，如可以是球型、弧型、双曲面型等等的曲面穹幕，根据不同形状的曲面穹幕，用于支撑曲面穹幕的钢结构也可以是不同形状，但具体的成形方法与布局相同。
如图1至图4所示，本发明中用于大型LED屏幕的钢结构包括有依序 连接的主钢构1、二次钢构2、三次钢构3和调整层6，以及用于连接主钢构1与二次钢构2的第一调整装置4，用于连接二次钢构2与三次钢构3的第二调整装置5，其中：
主钢构1由80方钢管焊接连接而成，也可以由螺栓连接固定而成，包括有10个围设成一个半球体的整体片架14，即10个整体片架14将半球体平均分成9等份，每一等份为20度，依次排列围成一个半球体。如图5所示，每个整体片架14包括有四根长短不同但平行直立设置的直立方钢管10，一根依据LED屏幕曲面形状预先弯曲成弧形的弧形方钢管13，四根直立方钢管10之间及直立方钢管10与弧形方钢管13之间由多根横向方钢管11连接固定成，形成一个整体，再在横向方钢管11与直立方钢管10之间形成的方形空间内设置有斜向方钢管12，用于增加整体片架14的强度。
但在实际施工过程中，先将直立方钢管10、横向方钢管11和斜向方钢管12焊接(也可以是螺栓)连接固定，形成局部片架，再焊接固定弧形方钢管13，形成整体片架14。本发明中的直立方钢管10、横向方钢管11、弧形方钢管13及斜向方钢管12均可以采用80方钢管，当然也可以采用不同型号的方钢管，但需要确保足够的强度。另，对于每个整个片架14中直立方钢管10的数量以及整体片架14的数量也不限于此，可以根据LED曲面屏幕的大小设定。
二次钢构2包括有21根上下平行且位于半球体纬线位置上的60圆钢管20，对于圆钢管20的数量可以根据LED屏幕的重量决定，并不限于此。每一根圆钢管20可以是一整根圆钢管弯曲成形，也可以是为了运输方便而分割成9等份，与整体片架14分割半球体的数量相对应，当然也可以是更多份。在圆钢管20与整体片架14之间由第一调整装置4连接固定，位于整体片架14的弧形方钢管13的内侧，如图7所示，利用第一调整装置4可以调整同一纬度上整根圆钢管20的弧度，以配合LED曲面屏幕的弧度。
三次钢构3为多根沿半球体径线位置分布的40方钢管30，并由第二调整装置5与二次钢构2的圆钢管20连接固定，如图8所示，位于二次钢构 2相对主钢构1的另一侧。三次钢构3中方钢管30之间的距离根据调整层6中开孔钢板60的尺寸设定，只需能将开孔钢板60固定在方钢管30中即可。
当然，当大型曲面LED屏幕不呈半球形，呈大型的曲面状时，三次钢构3中的方钢管30可以与二次钢构2中的圆钢管20呈纵横设置。
如图6a所示，调整层6固定安装在三次钢构3的内侧表面。调整层6包括多片开孔钢板60，每片开孔钢板60的尺寸与形成LED屏幕的LED单元的尺寸相对应，用于形成大型半球体LED屏幕的LED单元是将所有LED单元按经纬分割法，以最外圆向圆心等分110份，每份与圆心的夹角为1.65度，使得最外面最大的LED单元尺寸接近于常规的288*240mm设置。如图6b所示，每一片开孔钢板60中间开设有大型方孔61，用于固定LED单元模块时走线，同时在开孔钢板60的四周边缘开设有小方槽62，当两片开孔钢板60对接后形成一小方孔63，用于从LED屏幕后方观察LED单元模块的安装缝隙，另在每一片开孔钢板61的四个顶角上开设在弧形缺口64。每一片开孔钢板61通过自攻自钻螺钉固定在三次钢构3的方钢管30上，并根据开孔钢板61四个顶角的弧形缺口64进行平整固定，安装完成后形成双曲面。
如图7、图9和图10所示，第一调整装置4包括有L型固定件40、T型固定件41、第一抱箍42，L型固定件40的一边与整体片架14连接固定，另一边供T型固定件41的直杆43穿设，T型固定件41的直杆43通过调整螺栓46的连接，可以在L型固定件40的穿孔内作直线移动，在T型固定件41的端部经螺栓44连接有第一抱箍42，二次钢构2的圆钢管20插入第一抱箍42内，经由螺栓44与T型固定件41锁合，由于L型固定件40与T型固定件41不足以支撑二次钢构2、三次钢构3的重量，在整体片架14相对于L型固定件40的另一侧焊接固定有一支撑件45，圆钢管20先置于支撑件45的上方，再由第一抱箍42与T型固定件41紧固连接。通过调节调整螺栓46，可以调整圆钢管20的整体弧度，以适应LED曲面屏幕的 弧度。
第二调整装置5包括有两片直角固定件50、第二抱箍51及坚固螺栓52等连接件，两片直角固定件50分别位于三次钢构3的方形钢管30的两侧边，每个直角固定件50的一直角边由螺钉53与方形钢管30直接固定连接，另一直角边经由紧固螺栓52连接第二抱箍51，二次钢构2的圆钢管20穿设在第二抱箍51内，通过坚固螺栓52固定连接。
三次钢构3的方形钢管30由一整根方形钢管弯曲形成，也可以分隔成多段，连接成一整体，借助于第二抱箍51及紧固螺栓52的调节，可以调整方形钢管30的弧度，以配合LED曲面屏幕的弧度。在三次钢构3的方形钢管30上设置有扎线夹，方便电线的穿设、定位。
如图1至图4所示，形成本发明中的钢结构布局按以下步骤执行：
1、将80方钢管焊接形成由直立方钢管10、横向方钢管11、斜向方钢管12组成的局部片架，再焊接弧形方钢管13连接成整体片架14。将10个整体片架14按半球体作9等分分布设置固定，形成LED曲面屏幕的主钢架。采用全站仪进行每个点的尺寸复核。对于整体片架14的具体数量可以根据大型球面LED屏幕的大小来定，并不限于此，需要满足大型球面LED屏幕的支撑强度即可。
2、将60圆钢管20弯制成纬度杆件，作为二次钢构2。每根圆钢管20被分割成9等份，经由第一调整装置4分别连接在相邻的两个整体片架14之间，由第一调整装置4连接的同时可以对弧形圆钢管20进行弧度调节。完成后采用全站仪对每个点进行尺寸复核。
3、40方钢管的安装，将弯好的40方钢管与二次钢构2进行安装并调节尺寸。完成后，用全站仪进行每个点的尺寸复核。
4、最后安装各种尺寸的开孔钢板60，形成最后一道安装调整层6。开孔钢板60通过计算所得的尺寸，采用分别以不同的角度进行等分。开孔钢板60合理利用角度及四角缺口，将呈平面状的开孔钢板60安装成双曲面。
