Method for reinforcing local corrosion damage of angle steel member of power transmission tower
The invention discloses a method for reinforcing local corrosion damage of an angle steel component of a power transmission tower. A corroded angle steel main body of the power transmission tower, a reinforcing hoop, a full-length screw rod, an adjusting nut, repair angle steel and a repair hoop are included. The number of the reinforcing hoops is two, the reinforcing hoops are fixed to the two ends of the corrosion angle steel unit through bolts respectively, the hoops at the two ends are connected with the adjusting nuts through the full-length screws, and the distance between the reinforcing hoops at the two ends can be controlled through the adjusting nuts on the full-length screws, so that the tension and compression stress on an original corrosion angle steel body is replaced. After the repair angle steel welded with the connecting steel plate is attached to the corroded angle steel body, bolts are used for being connected with the repair angle steel through the holes in the connecting steel plate, the corroded angle steel body is clamped, and the effect that the repair angle steel and an original corroded component work together is achieved. Each hoop is divided into an inner hoop body and an outer hoop body which are connected through four bolts, and the inner hoop body and the outer hoop body are fixed to the angle steel body by fastening the four bolts. The number of the full-length bolts is two, the full-length bolts are used for connecting the hoops at the two ends, the distance between the hoops at the two ends can be changed by controlling the adjusting nuts, and tension and compression stress on the angle steel is transferred to the two full-length bolts in this way. The repairing angle steel is arranged on the corroded angle steel body, the repairing angle steel is fixed to the corroded angle steel body through bolts, it is guaranteed that the repairing angle steel repairs and reinforces the main material, and therefore the use performance of the power transmission tower is not affected.
本发明公开了一种输电铁塔角钢构件局部腐蚀损伤加固方法，其包括：输电塔受腐蚀角钢主体、加固抱箍、通长螺杆、调节螺母、修复角钢和修复抱箍。所述中的加固抱箍数量为两个，分别使用螺栓固定于腐蚀角钢单元的两端，两端抱箍通过通长螺杆与调节螺母相连，两端加固抱箍间的距离可通过通长螺母上的调节螺母控制，以此接替原受腐蚀角钢主体上的拉压应力，在用焊上连接钢板的修复角钢与受腐蚀角钢主体贴合后，使用螺栓通过连接钢板上的孔洞连接修复角钢，使其夹紧受腐蚀角钢主体，达到修复角钢与原腐蚀构件共同工作的效果。每个抱箍又分为内抱箍和外抱箍两部分，由四个螺栓相连，通过紧固四个螺栓将内外抱箍固定在角钢主体上。所述中的通长螺栓的数量为两个，为连接两端抱箍所用，通过对调节螺母的控制，可以改变两端抱箍之间的距离，通过这种方式将角钢上的拉压应力转移至两根通长螺杆上。所述中的修复角钢为设置在受腐蚀角钢主体上的修复方法，通过螺栓将修复角钢固定在受腐蚀角钢主体上，保证了修复角钢对主材的修复与加固，从而不影响输电塔的使用性能。
