Problems solved by technology

[0003] Bolts and nuts are one of the common fasteners. The existing bolts used to fix highway guardrails are generally standard bolts. Since the bolts used to fix highway guardrails are exposed to wind and rain all year round, they are often There is a phenomenon that the nut and the screw are separated, so that the expressway guardrail is fixed firmly, and then traffic accidents are caused. The existing nuts used to fix the expressway guardrail generally do not have anti-theft nut sleeves, so they cannot play the role of anti-theft.

Embodiment approach 1

[0040] After the nut 3 is screwed onto the screw rod 1, turn the rotating handle 8 so that the rotating shaft 5 rotates, the rotating shaft 5 drives the ring block 6 to rotate, the semicircle block 7 rotates with the ring block 6, and the semicircle block 7 makes the guide rod 13 to rotate The outer side moves, and the guide rod 13 pushes the arc block 12 to move. When the arc block 12 moves to the outside, when the bar 15 touches the nut 3, the bar 15 rotates to both sides, and the bar 15 blocks the nut 3, and the nut 3. After being stuck, after utilizing the through hole of the pin to pass the screw head 2 and the passage of the rotating shaft 5, the pin is welded dead.

Embodiment approach 2

[0042] After the nut 3 is screwed onto the screw rod 1, turn the rotating handle 8 so that the rotating shaft 5 rotates, the rotating shaft 5 drives the ring block 6 to rotate, the semicircle block 7 rotates with the ring block 6, and the semicircle block 7 makes the guide rod 13 to rotate Moving outside, the guide rod 13 pushes the arc block 12 to move. When the arc block 12 moves to the outside, the rack 16 follows the arc block 12 and moves to the outside. When the rack 16 is pressed against the nut 3, the rack 16 As soon as the groove of the fixed block 14 moves inwardly, the tooth bar 16 moves to make the gear 17 rotate, and the gear 17 rotates to spread the clip bar 15 and be stuck in the thread of the nut 3, so that the nut 3 is stuck. After the nut 3 is stuck, use After the passing of the pin through the through hole of the screw head 2 and the turning shaft 5, the pin is welded dead.

Abstract

The invention belongs to the technical field of highway guardrail fasteners, and particularly relates to an anti-theft installation method for highway guardrails. The method comprises the following steps that positioning and setting-out of vertical columns are carried out according to a design drawing; after the setting-out of the vertical columns is completed, the vertical columns are buried in soil and C25 concrete is poured; after the vertical columns are installed, corrugated beams are spliced to each another by splicing bolts and are fixed to the vertical columns by locking bolts; and after the locking bolts are installed, anti-blocking blocks are fixed between the vertical columns through connecting bolts to prevent the vertical columns from blocking wheels so as to avoid local forceon a guardrail and vehicle deceleration in a collision. When the highway guardrail is installed, the guardrail is locked, a good anti-theft effect is achieved, moreover, the bolts are subjected to wind blowing and raining all year round, nuts and screw rods cannot be detached from each other, and it is ensured that the fixing of the highway guardrail is firm.

Description

technical field [0001] The invention belongs to the technical field of expressway guardrail fasteners, in particular to an anti-theft installation method for expressway guardrails. Background technique [0002] my country's expressway was developed in the 1980s. At present, the mileage of domestic expressway has exceeded 100,000 kilometers, which plays a very important role in the development of the national economy and society. The highway crash barrier is the most important traffic infrastructure, and it is an important maintenance and safety guarantee facility for the highway. [0003] Bolts and nuts are one of the common fasteners. The existing bolts used to fix highway guardrails are generally standard bolts. Since the bolts used to fix highway guardrails are exposed to wind and rain all year round, they are often There is a phenomenon that the nut and the screw are separated, so that the expressway guardrail is fixed firmly, and then traffic accidents are caused. The ...
