Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically relating to a safety fence for construction. Background Technology

[0002] Construction safety fences are an indispensable safety facility in construction projects. They are mainly used to isolate construction areas, protect the safety of construction workers and passersby, prevent accidents, and promote the smooth progress of construction projects.

[0003] Traditional construction safety fences are mostly designed with a fixed height, which cannot be flexibly adjusted according to the specific needs of the construction site, thus limiting their use. Moreover, their warning effect relies mainly on simple color markings and reflective strips, which have limited warning effect at night, especially when visibility is poor. Utility Model Content

[0004] This invention discloses a construction safety fence, which aims to solve the following problems: traditional safety fences have a fixed height, which is not convenient to adjust the height flexibly according to needs, and the warning effect is limited at night or when visibility is poor.

[0005] To achieve the above objectives, the technical solution of this invention is as follows:

[0006] A construction safety fence includes a first enclosure panel and a second enclosure panel. Several sleeves are fixedly installed at the top of the second enclosure panel along a left-right direction. Extension rods are inserted into and pulled into the sleeves. A locking structure is provided between the extension rods and the sleeves. The top of the extension rods is fixedly connected to the bottom of the first enclosure panel. An infrared sensor is installed at the top of the first enclosure panel. A controller electrically connected to the infrared sensor is installed on the outer surface of the first enclosure panel. An alarm electrically connected to the controller is installed on the other outer surface of the first enclosure panel. LED strips are installed on both the front and rear outer surfaces of the first enclosure panel. A roller shutter structure connects the first and second enclosure panels.

[0007] Preferably, the first and second enclosures are provided with support columns on both sides, the support columns are detachably and fixedly connected to sleeves located at the left and right ends, the bottom end of the support column is provided with a support plate, and the four corners of the support plate are provided with fixing holes.

[0008] Preferably, at least one insertion block is provided on one side of the outer wall of the sleeve at the left and right ends, and concave blocks are provided on both sides of the support column to cooperate with the insertion blocks. The insertion blocks and the concave blocks are locked together by fastening bolts and fastening nuts.

[0009] Preferably, the locking structure includes multiple limiting holes and locking bolts on the extension rods at the left and right ends. The locking bolts pass through the sleeve and the limiting holes in sequence, and the other end of the locking bolts is provided with a threaded wing nut.

[0010] Preferably, solar panels are provided on both sides of the top of the first enclosure, and a storage battery for use with the solar panels is provided inside the first enclosure. The storage battery is electrically connected to an infrared sensor, a controller, a light strip, and an alarm.

[0011] Preferably, reflective strips are provided on both the front and rear outer surfaces of the second enclosure.

[0012] Preferably, the bottom of the first enclosure facing the construction site is fixedly provided with a shell in the left-right direction. Inside the shell, a winding roller is provided in the left-right direction and is rotatably connected to the shell. A roller shutter structure is wound on the winding roller. A torsion spring is connected between the central axis of the winding roller and the inner wall of the shell. Multiple support blocks are provided on the top of the second enclosure below the shell. The top of the support blocks is provided with hooks. The hooks are used in conjunction with the hanging rings at the bottom of the roller shutter structure. The bottom of the shell is provided with an outlet for the roller shutter structure to pass through.

[0013] The beneficial effects of this new type of construction safety fence are as follows:

[0014] 1. The height of the entire fence can be adjusted using extension rods, sleeves, limit holes, locking bolts, and wing nuts, making it suitable for different construction site needs and highly flexible in use.

[0015] 2. Through infrared sensors, controllers, and alarms, the system can detect the approach of people in the vicinity. Once a person or vehicle approaches within a preset safe distance, the alarm will sound, further enhancing the warning effect. With the auxiliary warning of the light strip, the overall warning effect is good, the safety is high, and it is easy to use at night or when visibility is poor. Attached Figure Description
