Description

Technical Field

[0001] The utility model relates to the field of construction safety, in particular to a door opening construction protection device. Background Art

[0002] When installing most door opening guardrails, you need to drill holes in the wall columns to install expansion bolts, and then wrap the expansion bolts and the vertical square tubes of the guardrails with iron wire to achieve the purpose of installing the guardrails. This installation method not only affects the appearance, but also affects the structural safety. When dismantling, the expansion bolts need to be cut off, which is time-consuming and laborious. At the same time, the wrapped iron wire will rust or loosen over time, which is more dangerous.

[0003] At present, most of the protective doors for edge door openings at construction sites of high-rise and super-high-rise buildings are standardized protection with relatively single sizes. However, with the development of the construction industry, the number of special-shaped structures has increased. For some door openings of different sizes, the standardized protection doors on the market are either less than the size of the door opening, leaving some space without protection, or exceed the size of the door opening, and cannot be installed between the two opposite walls of the door opening in a standard manner, and cannot form a complete shielding for effective protection of the edge opening, which can easily cause greater safety hazards.
