[0001] The present invention relates to the technical field of building construction, and in particular to a simple horizontal opening protection device and a use method thereof. Background Art

[0002] In construction engineering design, due to the functional needs of the building, many horizontal openings are often left in the building floor, such as chimneys, strong and weak current shafts, etc. Before the construction of the masonry structure, the horizontal openings on the floors pose a great safety hazard, especially during the dismantling of the internal frame, where the formwork and steel pipes are staggered. Workers are very likely to fail to notice the horizontal openings, and worker falls accidents often occur.

[0003] In previous construction processes, the protective measure for horizontal openings was to cover them with discarded formwork. Since the shape and size of the formwork were not processed, they did not meet the standard protection requirements.

[0004] Existing horizontal opening protection devices have the following defects: first, the safety protection function is insufficient. If heavy objects fall or people step on them, the single-layer protection device can hardly play a protective role; second, it does not serve as a warning when construction workers pass by at night, which is very dangerous. Summary of the Invention

[0010] Preferably, the crossbeam includes a first crossbeam and a second crossbeam, which are arranged in the space formed by the support beam and are effectively connected to the lower cover plate through the second type of cement nails.

[0011] Preferably, the warning device is made of luminescent material or night-time reflective material and is fixed to the upper surface of the upper cover by adhesion. The light sensing module includes a photoresistor, a battery and an LED light strip.
