Method for reinforcing pressed rod piece of grid structure
The invention relates to the field of steel structures and space structures, and discloses a grid structure pressed rod piece reinforcing method which comprises the steps that a filling hole is formed in the position, 100 mm away from a ball joint, of the first end of a pressed rod piece, and an exhaust hole is formed in the second end of the pressed rod piece; the type and parameters of the reactive powder concrete are selected according to the bearing capacity value, needing to be improved, of the pressed rod piece; and reactive powder concrete is poured into the pressed rod piece from the material filling hole to fill the pressed rod piece. According to the method for reinforcing the pressed rod piece of the grid structure, the high-strength and ultra-high-strength reactive powder concrete is used for replacing a low-strength common cement-based material and is filled into the pressed rod piece of the grid structure, the synergistic combination effect of the steel pipe and the RPC can be fully exerted, and the bearing capacity of the pressed rod piece of the grid structure is greatly improved.
本发明涉及钢结构与空间结构领域，公开了一种网架结构受压杆件加固方法，包括：在受压杆件的第一端距离球节点100mm处开设灌料孔，在受压杆件的第二端开设排气孔；根据受压杆件需要提升的承载力值，选定活性粉末混凝土的类型及参数；将活性粉末混凝土从灌料孔中灌入受压杆件内将其灌满。本发明提供一种网架结构受压杆件加固方法，将高强及超高强度的活性粉末混凝土替代低强度的普通水泥基材料，并内灌于网架结构的受压杆件之中，可以充分发挥钢管与RPC的协同组合作用，大幅度提升网架结构受压杆件的承载力。
