The invention provides a steel truss segmented hoisting construction method, which comprises a construction method, and the construction method comprises the following steps: step 1, selecting a stress point and a gravity center line; step 2, constructing a model: constructing a steel truss model consistent with reality through finite element numerical simulation software; thirdly, constraints in the X direction, the Y direction and the Z direction of the lifting hook are set, the specific shape and mode of the steel net frame are adjusted according to needs, and the limiting directions of the X direction, the Y direction and the Z direction of the steel rope are determined; and fourthly, the hanging beam is assembled. When the segmented hoisting construction device for the steel truss is used, the displacement of the limiting seat between the fixed seat and the movable seat is adjusted, the width between the bearing seats is adjusted, the bearing area of the steel truss with different lengths is adjusted, in addition, the bearing seats can be rotated on the limiting seat through the connecting seat according to the width of the steel truss while the bearing seats are horizontally adjusted, and the hoisting construction device is convenient to use. The bearing direction is changed through rotation, and hoisting of steel net racks of different sizes is achieved.
本发明提供一种钢网架分段吊装施工方法,包括施工方法,所述施工方法包括以下步骤:步骤一、选取受力点和重心线;步骤二、构建模型,通过有限元数值模拟软件构建与实际一致的钢网架模型;步骤三、设置吊钩X、Y、Z三个方向的约束,根据需要调整钢网架具体的形状和方式,确定钢绳索X、Y、Z三个的限位方向;步骤四、吊梁装配。该一种钢网架分段吊装施工装置,在使用时将限位座在固定座和活动座之间位移调整,调整承重座之间的宽度,对不同长度的钢网架调整承重面积,另外在承重座水平调整的同时根据钢网架的宽度可将承重座通过连接座在限位座上旋转,旋转改变承重方向,实现不同大小钢网架的吊装。
