Description

Lock joint formula highway guardrail Technical Field The utility model belongs to the technical field of highway guardrails, and particularly relates to a locking type highway guardrail. Background The highway guardrail is a belt-shaped protection energy-absorbing structure arranged on the outer side of a highway traffic lane or a central separation belt, is generally made of materials such as steel, aluminum alloy and the like, and aims to clearly show and transmit traffic information, maintain traffic order, absorb collision energy in a blocking mode, a self-deformation mode or a vehicle climbing mode and the like when the vehicle is out of control, thereby blocking the vehicle and reducing the injury degree to drivers and passengers. The utility model discloses a lock joint formula highway guardrail in bulletin number CN201095731Y, this patent designs the rail of integral type into the disconnect-type structure to add tapered end and lock body at two sections rail tip of separation, thereby realize the installation of lock joint formula, and reach the purpose of quick detach fast-assembling, and this kind of connected mode of above-mentioned patent wholly joint strength is not enough, in case receive the collision of car or pedestrian, very easily separates, can't reach the purpose of effective protection, so there is great limitation in the in-service use, has modifiable space. Disclosure of utility model The utility model aims to provide a locking type highway guardrail, which aims to solve the problems of insufficient connection strength and poor protection effect of the prior locking type highway guardrail in the prior art. The locking assembly comprises a connecting piece and a propping piece, wherein one end of the connecting piece is connected with the end plate in a penetrating way, one end of the connecting piece is screwed into the main supporting rod, the propping piece is sleeved on the connecting piece and is positioned between the connecting piece and the end plate, and the propping piece is propped against the end plate and the limiting bolt in the direction of the end plate, so that the purpose of fastening the end plate is achieved.
