Technical Field

[0001] The utility model relates to the technical field of guardrails, and particularly relates to a municipal combined quick-installation guardrail. Background Art

[0002] In municipal engineering, protective guardrails are a very common type of protective device, mainly used for protecting personal safety and equipment and facilities in places such as residences, roads, commercial areas, and public places.

[0003] In order to play a protective role, it is usually necessary to install them over a large area. When installing, it is necessary to arrange each guardrail in sequence, and several groups of bolts are used to connect between the guardrails. In this way, a large number of bolts need to be installed during installation, which is very inconvenient. Summary of the Utility Model

[0004] The purpose of this application is to provide a municipal combined quick-installation guardrail to solve the problems raised in the above background art.

[0005] To achieve the above purpose, this application provides the following technical solution: A municipal combined quick-installation guardrail includes several sequentially connected guardrail units. Each guardrail unit includes a first upright post, a second upright post, a first base, a second base, and a guardrail rod. A plurality of horizontally arranged guardrail rods are fixedly connected between the first upright post and the second upright post. The bottom end of the first upright post is fixedly installed with a first base, and the bottom end of the second upright post is fixedly installed with a second base. A T-shaped groove is provided on one side of the top end of the first base, and a T-shaped block is fixedly connected near one side of the top end of the second base. The T-shaped block and the T-shaped groove are adaptively inserted. A metal connecting sleeve is provided between adjacent guardrail units. Horizontally arranged through holes are opened at the top ends of the first upright post and the second upright post. The metal connecting sleeve is sleeved on the outer sides of adjacent first upright post and second upright post. A bolt passing through the through holes of the first upright post and the second upright post is threadedly connected to the metal connecting sleeve, and a locking nut is threadedly connected to the other end of the bolt.

[0006] Preferably, the outer side walls of the first upright post and the second upright post are closely attached to the inner side wall of the metal connecting sleeve.

[0007] Preferably, a reflective coating is applied to the outer surface of the guardrail rod.

[0008] Preferably, a fluorescent sign is fixedly installed on one of the guardrail rods in the middle of the guardrail unit.

[0009] Preferably, the upper surface of the T-shaped block is flush with the upper surfaces of the first base and the second base.

[0010] Preferably, bolt holes penetrating the upper and lower ends are provided on both the first base and the second base.

[0011] In summary, the technical effects and advantages of the present utility model are as follows:

[0012] In the present utility model, during installation, the T-shaped block of the second base of adjacent guardrail units is inserted into the T-shaped groove of the first base. Then, a metal connecting sleeve is sleeved on the tops of adjacent first columns and second columns. A bolt is screwed into one side of the metal connecting sleeve, and the screw sequentially passes through the through holes of the first column and the second column, and then is locked by a locking nut. Only 1 large bolt needs to be installed, which is very fast. BRIEF DESCRIPTION OF THE DRAWINGS
