Problems solved by technology

[0002] The existing building steel structure C-shaped steel is formed by cold bending of steel strips, see figure 1 , but the main problems of this structure are as follows: 1. The center line of the member is in an eccentric position, and it will be unstable and destroyed when the stress does not reach the limit state; 2. This member is a thin-walled opening member, and the opening immediately Variation, so there is a difference with the calculation model, resulting in design calculation errors;

Embodiment Construction

[0005] specific implementation plan

[0006] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing: The present invention adopts sheet material and profile to be connected with C-shaped steel at the opening of C-shaped steel to form C-shaped steel with ribs; image 3 , 4 , use the rib 2 and the C-shaped steel 1 to be intermittently connected through the weld 3 at the opening of the C-shaped steel; the rib is a plate or a profile; see the second embodiment Figure 5 , in order to increase the strength, the ribs can be placed obliquely in one direction; see Example 3 Figure 6 , in order to make the component stress reasonable, the ribs can also be placed obliquely in both directions; see the fourth embodiment Figure 7 , 8 , for the convenience of connecting ribs 4 can be bent; the present invention uses ribs to add to the opening of the C-shaped steel, which can greatly reduce the weight and effectively reduc...

Abstract

The invention discloses a C type steel with reinforcement fins for a building steel structure. The reinforcement fins are connected at an opening of the C type steel. The reinforcement fins can be vertical, or inclined in one way or inclined in two ways. The invention mainly aims to overcome the disadvantages of center bias and mechanical instability of conventional C type steel products. The bearing capacity of the C type steel is effectively improved and the cost is reduced. Therefore, the C type steel can be widely applied to the field of building steel structures.

Description

technical field [0001] The invention relates to a building steel structure product, in particular to a C-shaped steel for building steel structure with a reinforcing sheet. Background technique [0002] The existing building steel structure C-shaped steel is formed by cold bending of steel strips, see figure 1 , but the main problems of this structure are as follows: 1. The center line of the member is in an eccentric position, and it will be unstable and destroyed when the stress does not reach the limit state; 2. This member is a thin-walled opening member, and the opening immediately Variation, so there is a difference with the calculation model, resulting in design calculation errors; Contents of the invention [0003] The present invention proposes a C-shaped steel for building steel structure with reinforcement, which can improve the above shortcomings or deficiencies. The present invention is realized through the following technical solutions: A C-shaped steel for ...
