Description

Technical Field

[0001] This utility model relates to the field of construction guardrail technology, specifically a construction safety guardrail. Background Technology

[0002] With the continuous increase in urban infrastructure construction and various engineering projects, safety management at construction sites has become a crucial aspect of ensuring the safety of construction workers and the smooth progress of projects. Construction sites often present high-risk environments such as working at heights, near edges, and heavy traffic, which can easily lead to accidents such as falls, collisions, or accidental collapses. Therefore, installing construction safety railings has become one of the important measures to ensure the safety of construction areas.

[0003] Traditional construction safety barriers are mainly made of materials such as steel, iron rods, plastic, or wood. They are simple in structure, easy to install, and used to demarcate safety boundaries and prevent personnel from entering dangerous areas. However, existing barriers often have drawbacks such as high rigidity, susceptibility to damage, lack of flexible adjustment capabilities, and limited protective effects, making it difficult to meet the complex construction environment and diverse safety needs.

[0004] However, the applicant believes that the shortcomings are: 1. The structure of some guardrails is relatively complicated, making it inconvenient to quickly disassemble and adjust, which increases the labor cost and time consumption during construction; 2. Most guardrails do not integrate multiple functions such as reflection and warning, resulting in insufficient safety prompts and easy to cause misoperation.

[0005] Therefore, we have proposed a construction safety guardrail to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a construction safety guardrail to solve the problems mentioned in the background art.

The two ends of the second horizontal bar are respectively embedded in the two sets of sliding grooves on the left and right sides, and the second horizontal bar is slidably connected to the sliding groove.

[0009] The front sides of the two sets of columns are equipped with protective nets, and the four corners of the protective nets are fixedly equipped with connecting rings. The front sides of the columns are fixedly equipped with screws, and the screws are provided with upper and lower sets. The connecting rings are sleeved on the screws, and one end of the screws is threaded with a nut, and the nut presses the connecting rings tightly against the surface of the columns.

[0010] Preferably, the outer side of the column is welded with connectors, which enables the column to be connected to other components through the connectors.

[0011] Preferably, a warning strip is affixed to the front surface of the column, and reflective markings are provided inside the warning strip. Multiple sets of reflective markings are arranged at equal intervals, so that the device can play a clear warning role at night or in low-light environments.

[0012] Preferably, the card block has a fixing hole in the middle, and the top of the column is inserted with a rod. The rod passes through the card slot and through the fixing hole at the same time, which realizes the function of fixing the card block in the card slot and makes the device more stable.

[0013] Preferably, springs are welded to both ends of the second crossbar, and the other end of the spring is welded to one end inside the groove, so that the first and second crossbars have the function of extension and retraction, and the spring can hold the block against the groove.
