Description

[0002] The opening protection of the building structure at the construction site is an important part of the safety factors of the building structure. The quality of the opening protection is a measure to ensure the safe construction of the project. High-quality project safety construction also has strict requirements on the opening protection.

[0003] At present, the hole protection at the construction site of some projects has major safety hazards such as low coverage rate and insufficient rigidity of covering materials. Especially during the construction process at the construction site, the hole protection device usually uses glued wood formwork to cover the reserved holes for construction holes, line-laying holes and other projects. This covering method is inefficient and time-consuming, and wastes manpower and material resources. At the same time, the covering material has insufficient rigidity and low ability to withstand upper gravity, and this covering method is not eye-catching. When the upper part of the hole protection device is subjected to gravity, the covering material is easy to break and fall off, and when it is exposed to water and damp, the covering material becomes soft and cannot withstand the corresponding gravity. Therefore, this covering method cannot meet the needs of hole safety protection at the construction site and will bring other safety hazards. Utility Model Content

A tension valve 11 is installed at the connection between the first telescopic rod 1 and the second telescopic rod 3. By adjusting the tension valve 11, the first telescopic rod 1 can move relative to the second telescopic rod 3, so that the device is suitable for different working occasions.

[0030] A first aluminum alloy rod 201 is welded to the top of the first telescopic rod 1, and four first aluminum alloy rods 201 are connected to the four first telescopic rods 1 in sequence to form a rectangular frame. The bottom of the first aluminum alloy rod 201 is connected to the identification baffle 4 through the first hinge shaft 1201. A hole mark 5 can be pasted on the identification baffle 4 to improve the safety of the device while ensuring the stability of the device. A first rotating ball 131 is connected to the back of the identification baffle 4. The first rotating ball 131 is installed on the first rotating valve 9 of the first telescopic rod 1 through the first rotating rod. The first rotating ball 131 is driven to rotate through the first rotating valve 9, so that the identification baffle 4 can be effectively flipped and folded.

[0031] A second aluminum alloy rod 202 is welded to the lower part of the second telescopic rod 3, and four second aluminum alloy rods 202 are connected to the four second telescopic rods 3 in sequence to form a rectangular frame. A stainless steel angle iron 14 is welded to the bottom of the second telescopic rod 3, and a metal grip gasket 15 is welded to the stainless steel angle iron 14. A metal hole cover plate 7 is connected to the metal grip gasket 15 by bolts. The metal hole cover plate 7 is used to cover the hole to prevent people from falling.
