[0002] With the continuous development of steel structure metal roofs, large-size and large-scale skylights are increasingly widely used on metal roofs. However, the resulting pressure for construction safety guarantee is also increasing.

[0003] Before the installation and construction of a metal roof skylight, this part is a flat opening. To ensure construction safety, the horizontal protection of the opening plays an extremely important role. However, for large-size and large-scale roof skylights, the usual practice is to use steel pipe protection to set up edge protection to prevent people from approaching. However, for the completed metal roof surface layer, using steel pipe protection has a relatively large self-weight and there is a possibility of pollution and damage to the surface layer. Moreover, the construction is relatively cumbersome, the protection workload is huge, and it is easy to be damaged during the construction process and requires special personnel to restore it. Or use safety nets to set up flat protection. However, when facing large-size openings, it is difficult for personnel to work at the edge using safety flat nets, and the pulling effect is not good, and it cannot play a good protective role.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] Embodiment: As Figures 1 - 4 shown, a metal roof opening protection device includes a plurality of protection pipes 1 arranged in parallel. A protection net 2 is arranged between adjacent protection pipes 1. The protection net 2 adopts a safety flat net. A plurality of fixing plates 3 are arranged on both sides of the protection pipe 1. The fixing plates 3 adopt square iron sheets with round holes. The protection net 2 is connected to the fixing plates 3.

[0019] Furthermore, the protection pipe 1 is connected to the roof corrugation 4 through a fixing clamp. The fixing clamp includes a first fixing card 5. The first fixing card 5 is used for slidably plugging and connecting with the roof corrugation 4. The upper end of the first fixing card 5 is connected to a second fixing card 7 through a buckle assembly 6. The second fixing card 7 is plugged and connected to the protection pipe 1.

[0020] Furthermore, the first fixing card 5 includes two V-shaped parts 51 with opposite openings. The upper ends of the two V-shaped parts 51 are connected through a U-shaped part 52 with a downward opening. A first fixing bolt 53 is horizontally penetrated on the U-shaped part 52. By adjusting the first fixing bolt 53, the fastening degree between the first fixing card 5 and the roof corrugation 4 is controlled, facilitating the first fixing card 5 to slide back and forth on the roof corrugation 4.

[0021] Furthermore, the buckle assembly 6 includes an insertion plate 61 and a C-shaped slot 62. The insertion plate 61 is plugged and connected to the C-shaped slot 62. A groove 63 is arranged in the middle of the insertion plate 61. A convex block 64 is arranged inside the C-shaped slot 62. The convex block 64 is plugged and connected to the groove 63; the insertion plate 61 is integrally welded with the first fixing card 5, and the C-shaped slot 62 is integrally welded with the second fixing card 7.

[0022] Furthermore, the second fixing card 7 includes an upper arc pipe clamp 71 and a lower arc pipe clamp 72. The upper arc pipe clamp 71 and the lower arc pipe clamp 72 are connected through a plurality of second fixing bolts 73.

[0023] In this embodiment, the protection pipe 1, the fixing plate 3 and the fixing clamp are all galvanized to prevent rust; the safety flat net is made of nylon material and has a flame retardant property.
