Embodiment 1

[0036] The embodiment of the present application discloses a connection structure between a concrete guardrail and a corrugated beam guardrail. refer to figure 1 and figure 2 , including a concrete fence body 1, the concrete fence body 1 extends in the horizontal direction, and the concrete fence body 1 is used to separate the highway, so that the car can only drive in the space separated by the two concrete fence bodies 1. The concrete fence body 1 is provided with a corrugated beam body 2 , and the corrugated beam body 2 is arranged on the side of the concrete fence body 1 close to another concrete fence body 1 . When the car deviates and hits the concrete fence body 1, the car first hits the corrugated beam body 2, the corrugated beam body 2 can deform and absorb the kinetic energy of the car, thereby reducing the harm of the accident to the driver, and the concrete fence body 1 can continue to absorb The kinetic energy of the car, thereby reducing the probability of the...

Embodiment 2

[0042] The embodiment of the present application discloses a connection structure between a concrete guardrail and a corrugated beam guardrail. refer to image 3 On the basis of Embodiment 1, the abutting portion 33 is provided with abutting bolts 34, the abutting bolts 34 are arranged perpendicular to the abutting portion 33, and the abutting bolts 34 penetrate through the abutting portion 33 and are screwed with the abutting portion 33 . The end of the abutting bolt 34 close to the concrete fence 1 can abut on the concrete fence 1 . When the length of the hoisting portion 32 is greater than the width of the concrete fence 1, it is difficult for the connecting portion 31 and the abutting portion 33 to be stuck on the side wall of the concrete fence 1 at the same time. The bolts 34 abut on the concrete fence body 1 , so that the connection mechanism 3 is tightly connected to the concrete fence body 1 , and the probability of the connection mechanism 3 shaking on the concrete...

Embodiment 3

[0044] The embodiment of the present application discloses a connection structure between a concrete guardrail and a corrugated beam guardrail. refer to Figure 4 On the basis of Embodiment 2, two abutting bolts 34 are provided, and the two abutting bolts 34 are screwed on the connecting portion 31 and the abutting portion 33 respectively. The abutting bolts 34 are perpendicular to the connecting portion 31 , and the ends of the abutting bolts 34 can abut on the inclined surface 11 , thereby improving the stability of the connecting mechanism 3 on the concrete fence 1 .

Abstract

The invention relates to a concrete guardrail and corrugated beam guardrail connecting structure, which relates to the technical field of road guardrails, and comprises a concrete guardrail body, a corrugated beam body is arranged on the concrete guardrail body, the corrugated beam body is arranged on the side surface of the concrete guardrail body, a plurality of connecting mechanisms are arranged on the corrugated beam body, and each connecting mechanism comprises a connecting part, a hoisting part and an abutting part. The two ends of the hoisting part are connected to the connecting part and the abutting part respectively, the hoisting part is arranged on the top of the concrete fence body, the connecting part and the abutting part are clamped to the two side walls of the concrete fence body respectively, and the wave-shaped beam body is fixedly connected to the connecting part. The corrugated beam guardrail has the effect that the corrugated beam guardrail can be conveniently and rapidly installed on the concrete guardrail.

Description

technical field [0001] The present application relates to the technical field of highway guardrails, and in particular, to a connection structure between a concrete guardrail and a corrugated beam guardrail. Background technique [0002] The highway guardrail is a railing structure set on both sides of the highway, which plays the role of guiding and diverting. Common highway guardrails include concrete guardrails and wave beam guardrails. Concrete guardrails have the advantages of high structural strength and impact resistance. The wave beam guardrail is a beam with a wavy cross-section. When a car hits the wave beam guardrail, the wave beam guardrail can be deformed. And absorb the shock of the car. [0003] The connection between the existing concrete guardrail and the wave beam guardrail needs to drill holes on the concrete guardrail. By setting bolts or pins in the holes of the concrete guardrail, a metal frame is arranged on the concrete guardrail, and the metal frame...
