背景技术
目前，装配式的各种桁架支撑体其结构杆件间的连接技术很多，大多数的连接节点技术，包括扣接头连接技术，都需要使用连接螺栓锁紧连接，互相连接的结构杆件之间传递应力时需要连接螺栓直接受拉、受压或受剪切的方式传递，其安全性、可靠性、耐久性不理想，结构杆件的装配施工过程对工人的工艺要求高，劳动强度大，而最新的、无需连接螺栓的连接头为套接头，但是套接头由于是一个完整的圆筒体结构，其装配施工时受很多限制，其必须由要相连接的连通杆件端部套入，且其由于是一个完整的圆筒体，所以其所构成的连接杆件无法实施同级间的延伸连接，套接头的应用及装配施工极不便利。

具体实施方式：
一种自扣紧杆件连接头，它包括：长接头(1)、短接头(2)；长接头及短接头分置于长条形杆身的两端与其固定连接成为连接杆件，所述的长接头(1)包括：长连接部(3)、长扣紧斜面(7)、长扣接部(4)；所述的短接头(2)包括：短连接部(5)、短扣紧斜面(8)、短扣接部(6)、短连接加强件(10+18)；两根连接杆件上所述的长扣接部(4)与所述的短扣接部(6)上下错位相向贴紧于要连接的连通杆件(14)，并沿连通杆件(14)轴线方向相向滑动对扣，所述的长扣紧斜面(7)与短扣紧斜面(8)互相向挤压作用下令所述的长扣接部(4)与短扣接部(6)形成 不断缩小的空腔与连通杆件(14)贴合扣紧连接,同时还令所述的长接头(1)与所述的短接头(2)相互扣紧连接，完成以所述的长接头及短接头为特征的连接杆件间的同级延伸连接。
所述的自扣紧杆件连接头，其所述的长接头(1)为一整体的构件，其水平截面如大写英文字母U,其有一定厚度、高度，一种应用其实施的连接杆件，其长接头(1)高度为连接杆件杆身(13)直径的两倍，其U字形底部园弧段为长扣接部(4)，长扣接部(4)水平截面的内直径与要连接的连通杆件(14)水平截面的外直径同；其U字形两侧对称的两直边段为长连接部(3)，长连接部(3)设置有定位螺栓孔(11)，两边长连接部(3)内侧对称设置长扣紧斜面(7)，所述的长扣紧斜面(7)为向内凸出长连接部(3)内表面的一个倾斜面，该倾斜面上边近向长扣接部(4)，下边远向长扣接部(4)，并且该倾斜面的水平截面边由长连接部(3)外侧向端远向长扣接部(4)到内侧向端近向长扣接部(4)倾斜。
所述的自扣紧杆件连接头，其所述的短接头(2)包括：短连接部(5)、短扣紧斜面(8)、短扣接部(6)、短连接加强件(10+18)；所述的短连接部(5)、短扣紧斜面(8)、短扣接部(6)、短连接加强件(10+18)为同质的一整体构件，所述的短扣接部(6)为有一定厚度，高度与所述的长接头高度同；所述的短扣接部(6)其水平截面为稍小于半个圆的构件，其水平截面的内直径与要连接的连通杆件(14)水平截面的外直径同，短扣接部(6)的两直边的外径方向固定连接两平行的高度与短扣接部(6)高度同的短连接部(5)，所述的两个短连接部(5)中间设置短连接加强件(10+18)，所述的短连接部(5)远向短扣接部(6)的端面为短扣紧斜面(8)，所述的短扣紧斜面(8)上边近向短扣接部(6)，下边远向短扣接部(6)倾斜，同时所述的短扣紧斜面(8)的水平截面边由外端远向短扣接部(6)向内端近向短扣接部(6)倾斜；每个短扣紧斜面(8)两方向的倾斜斜率相应的与所述的长扣紧斜面(7)的两个方向的倾斜斜率相一致，尺寸匹配，令完成自扣紧连接后的短扣紧斜面(8)与长扣紧斜面(7)互相完全紧密贴合，并高度端对齐；一种本发明实施的长接头及短接头其长扣紧斜面及短扣紧斜面的上边与下边水平投影距离小于其垂直高度的十分之一，其水平截面边与短连接部(5)外侧边夹角为60度，与短连接部内侧边夹角为120度；应用本发明实施的连接杆件一端为长接头，另一端为短接头，其同级延伸连接时，一根连接杆件的短接头端短扣接部(6)贴紧于要连接的连通杆件(14)，另一根连接杆件的长接头端与前根连接杆件相向并上下错开扣入连通杆件(14)，使长扣接部贴紧于连通杆件(14)，随后沿连通杆件(14)轴线方向向下滑动，所述的长扣紧斜面与所述的短扣紧斜面便相互挤压作用令长扣接部与短扣接部形成的空腔不断缩小并最终与连通杆件扣紧，连接完成的长接头与短接头高度对齐；两根连接杆件的同级延伸连接只需一个相向滑动对扣的动作便完成，而且与长接头与短接头的型号大小无关，极大的简化安装施工的工艺，由于长扣紧斜面与短扣紧斜面完全相互贴紧挤压，其接触面积很容易做到大于长接头最薄处的垂直截面面积，因而可以高强度承载传递应力，完成自扣紧连接的长接头与短接头形成一个完整的整体；所述的自扣紧杆件连接头，其所述的长连接部(3)还设置有定位螺栓孔(11)，每边长连接部(3)至少设置有两个定位螺栓孔(11)，两边对称成对设置，当所述的长接头(1)与所述的短接头(2)自扣紧连接后，穿越定位螺栓孔(11)的上定位螺栓(16)、下定位螺栓(17)分置于短连接加强主件(10)的上、下，此时的定位螺栓(16)、(17)并不直接传递连接杆件间的应力，但锁紧的定位螺栓(16)、(17)增加了长连接部(3)与短连接部(5)间贴紧固定的摩擦力，起到固定长接头与短接头相对位置的作用，由于定位螺栓(16)、(17)不直接传递应力，所以相对于现有技术的其它种连接头，承载相同应力的同型号连接杆件，本发明的自扣紧杆件连接头螺栓使用量大为减少，越是尺寸大的型号节省越多。
