Description

Technical Field

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

[0002] With the continuous expansion and increasing complexity of construction projects, the requirements for safety railings are also rising. Traditional safety railings have many shortcomings in terms of materials, structure, installation, and durability, making it difficult to meet modern construction safety standards. Therefore, modern safety railing technology utilizes high-strength, corrosion-resistant steel or aluminum alloy materials, combined with precise structural design and optimized processing techniques such as die casting and laser cutting, ensuring the stability, durability, and ease of installation of the railings. Simultaneously, surface treatment technologies such as baking paint not only improve the corrosion resistance of the railings but also give them an aesthetically pleasing appearance.

[0003] A search revealed Chinese patent application number 202023034704.0, which discloses a protective railing for construction projects. The railing includes a lower crossbeam with a right and left upright post on each side. A lower support is slidably connected to the bottom of each post, and a support leg is fixedly connected to the bottom of the lower support. Fixed posts are fixedly connected to both sides of the front surface of the lower crossbeam. Limit sleeves are slidably connected to the surface of each fixed post, and springs are fitted onto the surface of each fixed post. The front and rear ends of the springs are welded to the fixed posts and the limit sleeves, respectively. This invention incorporates an infrared sensor that receives infrared radiation from the human body. When someone enters the sensing range, the infrared sensor detects a change in the human infrared spectrum, and the switch automatically connects the load. The switch remains on as long as the person remains within the sensing range. After the person leaves or remains inactive within the sensing area, the switch automatically shuts off the load after a delay. This design offers advantages such as good protective effect and convenient assembly / disassembly.

[0004] However, the aforementioned type of guardrail used in construction projects still has the following drawbacks:
