Abstract
Description
Technical Field
[0001] This utility model belongs to the field of construction site safety, and specifically relates to a safety isolation bracket for construction projects. Background Technology
[0002] Construction sites typically use safety ropes for isolation to prevent unauthorized personnel from entering the site and ensure construction safety. In addition, safety ropes are widely used during construction and maintenance, and sometimes fences are used to isolate construction areas. Construction site environments are complex and changeable, especially with overlapping construction activities, road repairs, and pressure vessel installations, which place extremely high demands on safety protection performance. Existing fences and safety ropes lack alarm functions, making it difficult for management personnel to promptly detect and stop unauthorized crossings, thus affecting construction safety. Relying entirely on manual inspections for safe construction makes it difficult to achieve comprehensive, uninterrupted monitoring of the construction site and to completely isolate the construction area.

The top of the support column has a through hole, and the bottom of the support column is connected to a base with a through hole for installing expansion bolts. Two L-shaped rods are located on either side of the sleeve, with their opposite ends fitted into the sleeve and the lower end of the L-shaped rod fitted into the through hole of the support column. The alarm device is installed inside the support column. The alarm device includes: a connecting plate, a spring, a fixed plate, a support plate, a contact switch, a buzzer, and a movable rod. The connecting plate is connected to the lower end of the L-shaped rod. The two ends of the spring are connected between the connecting plate and the fixed plate, respectively. The two sides of the fixed plate are connected to the inner wall of the support column. A through hole is provided in the middle of the fixed plate. The movable rod is fitted into the through hole of the fixed plate, and the top of the movable rod is connected to the bottom of the connecting plate. The two sides of the support plate are connected to the inner wall of the support column. The support plate is located below the fixed plate. The contact switch is fixed on the support plate and is located below the movable rod. The contact switch is connected to a buzzer or an audible and visual alarm device through a wire.
[0006] Furthermore, the buzzer is fixed to the outer wall of the support column.
[0007] Furthermore, the contact switch is fixed in the middle of the support plate, and the buzzer is powered by a built-in battery.

[0017] Safety isolation brackets for building construction include: support columns 1, protective rods 2, sleeves 3, L-shaped rods 4, and an alarm device. The protective rods 2 and sleeves 3 are located between two support columns 1. One protective rod 2 is fitted onto each side of each sleeve 3, with one end of the protective rod 2 fitted inside the sleeve 3 and the other end connected to the support column 1. The top of the support column 1 has a through hole, and the bottom of the support column 1 is connected to a base 11. The base 11 has a through hole 12 for installing expansion bolts. Two L-shaped rods 4 are located on either side of the sleeve 3, with their opposite ends fitted inside the sleeve 3. The lower end of the L-shaped rod 4 is fitted into the through hole of the support column. The alarm device is installed inside the support column 1 and includes... The components include: a connecting plate 5, a spring 6, a fixed plate 7, a support plate 8, a contact switch 9, a buzzer 10, and a movable rod 13. The connecting plate 5 is connected to the lower end of the L-shaped rod 4. The two ends of the spring 6 are connected between the connecting plate 5 and the fixed plate 7, respectively. The fixed plate 7 is connected to the inner wall of the support column 1 on both sides. The fixed plate 7 has a through hole in the middle. The movable rod 13 is fitted into the through hole of the fixed plate, and the top of the movable rod 13 is connected to the bottom of the connecting plate 5.
