In order to solve the problems of the technologies described above, a kind of rigidity of the utility model is pieced together the switch cabinet body of the high rigidity of envelope, comprise framework, some side plates, framework is formed by fixedly connecting by many crossbeams and column, described side plate surrounds framework the installing space of some installation components and parts, wherein, described side plate is the flute profile tabular component that both sides have flanging.
Above-mentioned a kind of rigidity is pieced together the switch cabinet body of the high rigidity of envelope, and wherein, the section bar cross sectional shape of described crossbeam is a C shape, and the two ends of described crossbeam all are fixed with a shut.
Above-mentioned a kind of rigidity is pieced together the switch cabinet body of the high rigidity of envelope, and wherein, the section bar cross sectional shape of described column is a G shape, and the two ends of described column all are fixed with a shut.
The utility model can be practical following beneficial effect:
1, because described side plate is a channel member, and during connection, side plate and framework support mutually, interconnect to be integral, and have strengthened the integral rigidity of cabinet, improves the local stiffness level, thereby improved the rigidity of switch cabinet body, the fail safe that has improved switch cubicle.
2, because the section bar cross sectional shape of described crossbeam is a C shape, the economical rationality of C shaped steel cross sectional shape, mechanical property is good, and rigidity is strong, therefore, has improved the rigidity of cabinet, and switch cubicle rigidity has been improved.
3, because the section bar cross sectional shape of described column is a G shape, and G type section bar has the cross section function admirable, therefore the advantage that intensity is high, improves switch cabinet body rigidity, thereby has further improved the general safety performance of switch cubicle.
Therefore, integral body of the present utility model and local stiffness are all relatively good, during use, can bear bigger impulsive force, thereby have improved the overall security of switch cubicle; And the utility model has only changed the structure of column, crossbeam and side plate, and is therefore, simple in structure, easy to process.
