Description

A safety protection device for building construction

technical field

The invention relates to the technical field of construction protection devices, and more particularly, to a construction safety protection device.

Background technique

Building construction is a production activity that people use various building materials, machinery and equipment to build various building products in a certain space and time according to a specific design blueprint. It includes the entire production process from construction preparation, ground breaking to project completion acceptance. In the process of building a house, construction needs to be carried out on the basis of the built one floor. The construction is carried out in good weather. When the construction is carried out on the built floor, due to the hot weather, the construction personnel usually carry out the construction under the sun without shielding protection. When the construction time is long, the construction personnel are in the hot sun There will be a lot of sweating, and the danger of heat stroke will occur in serious cases. Moreover, in the hot sun, if the time is too long, it will cause sunburn and peeling of the exposed skin, which makes the personal safety and health of construction workers. Therefore, it is particularly important to propose a protective device that can protect the construction personnel in hot weather. In addition, although the construction protective devices in other existing patent technologies can be expanded and assembled according to different construction areas, or It can realize the mounting of protective cloth under the condition of sunlight, but at the same time realize the protective device that can carry recyclable protective cloth and can be assembled according to different areas.
