the term

As used herein, the terms "reinforced concrete crash barrier", "reinforced concrete crash barrier of the present utility model", or "collision barrier of the present utility model" can be used interchangeably, referring to the utility model described in the first aspect Reinforced concrete crash barriers.

For ease of description, the utility model is further described below in conjunction with the accompanying drawings. It should be understood that these drawings are not intended to limit the scope of the present invention.

In the present utility model, typically, the substructure of the reinforced concrete anti-collision barrier includes a part buried under the ground. For example, concrete blocks with a buried depth of about 0.5m can be used, and the part above the ground adopts an anti-collision pier shape that is conducive to energy consumption, so as to meet the A-level anti-collision requirements.

Preferably, the anti-collision pier requires a certain burial depth, such as 0.4-0.6m or deeper. Because the upper entity enclosure height of the anti-collision guardrail of the present utility model is higher, in some special areas or the monsoon load is larger, the lower foundation must have certain anti-overturning ability.

The upper part of the anti-collision pier is pre-embedded with 150mm×150mm galvanized steel embedded parts, which are used for welding with the upper square steel pipe during the installation stage (see Figure 1 for details).

In the present utility model, the upper part of the reinforced concrete anti-collision guardrail preferably adopts a solid fence, and the height is not lower than the height of a person's climbing and parabolic height. Bending moment due to wind load.

In a preferred example, the upper structure of the anti-collision guardrail of the present utility model adopts a 50mm square steel pipe, which is connected with the lower structure by welding or by other means (such as bolting).

In addition, in order to reinforce or increase the strength of the superstructure, one or more auxiliary reinforcing ribs can be provided. Usually, the auxiliary reinforcing ribs include auxiliary reinforcing ribs arranged longitudinally, transversely and/or obliquely.

In a preferred example of the present invention, the auxiliary reinforcing rib is an angle steel.

In another preferred example, the distance between the square steel pipes is about 1.2-2.0m (such as about 1500mm), and angle steels are used to fix the square steel pipes to enhance rigidity and integrity.

The main fence is made of color steel plate, the color steel plate is rich in color, easy to purchase, and can meet different appearance requirements. (See Figure 2 for details)

The main advantages of the utility model include:

1. Simple structure and convenient construction.

2. Anti-falling, overturning, parabolic and anti-collision functions.

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model.

As shown in Fig. 1 and Fig. 2, the reinforced concrete anti-collision guardrail of an embodiment of the present invention comprises one or more anti-collision units, wherein, each anti-collision unit comprises: reinforced concrete base part 10, superstructure 30, and A fixture for fixing the upper structure to the base part; the base part includes: a base lower part 12, a base middle part 14 and a base upper part 16, and the base lower part 12, the base The seat middle part 14 and the base upper part 16 are integral and the base parts are piers; the top surface of the base upper part 16 is provided with a reserved hole 18 for fixing the upper structure; The fixing piece is arranged in the hole.

The lower part 12 of the anti-collision guardrail base is a platform-shaped concrete structure, which is buried under the ground 1 .

For the anti-collision barrier, the thickness of the upper part of the base is 0.25-0.80 meters. As the height of the supporting steel pipe 32 increases, the thickness of the base upper portion 16 gradually decreases. The fixing parts of the anti-collision barrier include galvanized steel embedded parts pre-embedded in the reserved holes 18 .

The upper structure of the crash barrier includes: supporting steel pipes 32 , auxiliary reinforcing ribs 34 and guardrail boards 36 , wherein the guardrail boards are fixedly connected to the supporting steel pipes 32 and to the auxiliary reinforcing ribs 34 . The supporting steel pipe 32 includes a square steel pipe and a hexagonal steel pipe; the diameter of the square steel pipe is 40-60 mm; the thickness of the supporting steel pipe 32 is 40-60 mm.

First of all, the lower structure adopts concrete blocks with a buried depth of about 0.5m, and the part above the ground adopts the anti-collision pier shape that is conducive to energy consumption, which meets the A-level anti-collision requirements. The reason why the anti-collision pier needs a certain buried depth is that the height of the upper solid enclosure is relatively high, and the wind load is relatively large in some special areas, so the lower foundation must have a certain anti-overturning ability. The upper part of the anti-collision pier is pre-embedded with 150mm×150mm galvanized steel embedded parts, which are used for welding with the upper square steel pipe during the installation stage.

The 16 structure on the upper part of the base adopts 50mm square steel pipes and the lower structure is connected by welding; the distance between the square steel pipes is 1500mm, and the square steel pipes are fixed with angle steel to strengthen the rigidity and integrity; the main enclosure of the square steel pipes is made of color steel plates, and the color Rich, easy to purchase, can meet different appearance requirements.
