Three-wave anti-blocking block

Abstract

The invention discloses a three-wave anti-blocking block which comprises an anti-blocking block body. The anti-blocking block body is of a U-shaped structure. Small edges on the two sides of the anti-blocking block are formed on the top of the anti-blocking block body. Anti-blocking block lugs are symmetrically formed on the two sides of the anti-blocking block body. The anti-blocking block lug islocated at one end of the anti-blocking block body, an anti-blocking block tail small edge is formed at the bottom of the other end of the anti-blocking block body, the anti-blocking block tail smalledge is connected with the surface of the bottom face of the anti-blocking block body, and anti-blocking block tightening screw holes are symmetrically formed in the surfaces of the two sides of theanti-blocking block body. Beneficial effects are that: the three-wave anti-blocking block adopts a non-welding integrated structure, the situation that welding fume generated by welding pollutes the environment in the production process is avoided, harm to the body of a production worker is reduced, punching forming is adopted for integrated forming, the product size is standard, the product has better connectivity and is stressed evenly, the cracking possibility is reduced, and then potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of highway guardrail accessories, in particular to a three-wave anti-blocking block. Background technique [0002] In the prior art, the anti-blocking block is applied to the guardrail of the expressway, which is suitable for the complex types of vehicles in the traffic, and the fear that the collision vehicle may block the road section at the guardrail column; In the affected section, the anti-blocking block itself is an energy-absorbing structure. The anti-blocking block is generally welded and formed by a plurality of large and small laths. The analysis shows that: the product is composed of welding, and the welding part will appear uneven, making the product appearance unattractive; the product welding is prone to errors, and then there will be irregularities or deviations in hole spacing, etc., which will increase the labor force of workers during the installation process. Large, thereby reducing the ...

Problems solved by technology

The analysis shows that: the product is composed of welding, and the welding part will appear uneven, making the product appearance unattractive; the product welding is prone to errors, and then there will be irregularities or deviations in hole spacing, etc., which will increase the labor force of workers during the installation process. Large, thereby reducing the progress of the project; in the process of use, the tensile strength of the welding part of the product is obviously insufficient, and it is easy to crack, which is easy to cause safety hazards
