Embodiment Construction

[0013] The specific implementation, structure, features and effects provided by the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Such as Figure 1~2 A kind of upright section steel shown, comprises skeleton and the installation hole that has on the skeleton, and skeleton 17 is a cylinder, and the cross section of cylinder is a closed figure, and side one 14 and side two 15 of skeleton are respectively provided with installation hole 16, installs The holes are circular holes and rectangular holes, and are evenly distributed along the longitudinal direction of the skeleton. The closed figure of the cross-section of the cylinder is extended from the starting point 0 to the right, the first pleat 1 is folded 90 degrees downward, the second pleat 2 is folded 90 degrees to the right, the third pleat 3 is folded 90 degrees downward, and the pleat 3 is folded 19.5 degrees downward to the left The...

Abstract

The invention relates to pillar steel. The steel comprises: a skeleton and an installing hole in the skeleton. The skeleton is a cylinder. A cross section of the cylinder is a closed figure. A side face 1 and a side face 2 of the skeleton are equipped with the installing holes respectively. The closed figure of the cross section of the cylinder is formed through the following steps: extending rightward from a starting end; folding a first pleat 90 DEG downwards; folding a second pleat 90 DEG rightwards; folding a third pleat 90 DEG downwards; folding a fourth pleat 19.5 DEG leftwards and downwards; folding a double-layer edge and a fifth pleat 180 DEG upwards and folding a sixth pleat 160.5 DEG upwards; folding a seventh pleat 90 DEG leftwards; folding a eighth pleat 91 DEG upwards; folding a ninth pleat 90 DEG rightwards; folding a tenth pleat 90 DEG upwards; folding a eleventh pleat 90 DEG leftwards; folding a twelfth pleat 180 DEG rightwards; merging two layers of sheet materials and ending to a tail end. Two places of double layer folding is performed to the skeleton in the invention. Intensity is large and weight is light. A standardization degree of a cabinet can be guaranteed. A side plate and a door plate of the cabinet can be effectively installed. The intensity and a protection grade of the cabinet can be guaranteed. The steel is suitable for many kinds of the cabinets.

Description

technical field [0001] The invention belongs to the field of metal hollow section steel processing and application, relates to a column section steel, and is especially suitable for industrial cabinet doors. Background technique [0002] With the development of the power distribution industry, its technical performance requirements for practicality and safety have increased, and the performance requirements for the profiles used in industrial cabinets have also become higher and higher. At present, the column steel skeleton structure used in industrial cabinet doors cannot meet the requirements. The user's requirements for mechanical strength and rigidity and protection level. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and to provide a column shaped steel. The frame adopts two double-fold folds, which has high strength and light weight, which can ensure the standardization of the ca...
