Cross-shaped steel structure reinforcing rib

Abstract

The invention discloses a cross-shaped steel structure reinforcing rib. The reinforcing rib comprises a reinforcing rib body and a roller unit, the reinforcing rib body comprises a main rib, a main rib groove is formed in the main rib, auxiliary ribs are arranged on the two sides of the main rib, and auxiliary grooves are formed in the auxiliary ribs; first through holes are formed in the main riband in the auxiliary ribs. The reinforcing rib comprises rib grooves and a fixing plate and can avoid safety hidden hazards of welding on products compared with a welded reinforcing rib. Besides, thereinforcing rib fixedly connected through bolts can be detached and replaced, and the service life of the products is prolonged. The main rib and the auxiliary ribs are arranged, the side faces of the ribs have inclined angles, and the edges of the ejection faces of the ribs are subjected to grinding. Compared with ridged reinforcing ribs connected perpendicularly, the reinforcing rib can eliminate the excessive stress concentration phenomenon and prolong the service life. An anti-shock pad is arranged so that the shock resistance of a fastening mechanism can be enhanced.

Description

technical field [0001] The invention relates to the technical field of reinforcing bars, in particular to a cross-shaped steel structure reinforcing bar. Background technique [0002] In the process of structural design, there may be situations where the overhanging surface of the structure is too large, or the span is too large. Add a reinforcement plate, commonly known as a reinforcement rib, to increase the strength of the joint surface. [0003] However, the traditional reinforcing rib is a rectangular column attached to the surface of the product that needs to be strengthened in rigidity and strength. This single structure cannot be adapted to all products, and the traditional reinforcement is fixedly connected to the surface of the product through right-angle welding, which is not easy to replace. Long-term Due to the action of physical force, there will be open welding, and the traditional ribs will have obvious edges and corners, and the ribs and the contact surface...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a cross-shaped steel structure reinforcement to solve the problem that the traditional reinforcement proposed in the above background technology is a rectangular column attached to the surface of a product that needs to be reinforced in rigidity and strength. This single structure cannot adapt All products, and the traditional reinforcement is fixedly connected to the surface of the product through right-angle welding, it is not easy to replace, and the welding phenomenon will appear due to the long-term physical force, and the traditional reinforcement will have obvious edges and corners, and the ribs and the contact surface are formed. 90° right-angle connection, this kind of rib will cause excessive stress concentration, which will reduce the stiffness and strength of the rib and the product, and reduce the service life of the product
