It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] The present utility model will be further described below in conjunction with the accompanying drawings.

[0020] As Figures 1-4 shown, a safety net for construction engineering includes a plurality of first wire netting bones 1 and a plurality of second wire netting bones 2. The plurality of first wire netting bones 1 and the plurality of second wire netting bones 2 are connected in a crisscross manner to form a net body 3. A set of blocking component is connected in each grid of the net body 3; Pulling ropes 4 are connected to the upper and lower ends of the net body 3 respectively, and positioning rings 5 are connected to both ends of the pulling ropes 4.

[0021] As Figure 4 shown, the blocking component includes an upper blocking curtain block 6 and a lower blocking curtain block 7. The upper blocking curtain block 6 and the lower blocking curtain block 7 are respectively connected to the upper and lower sides of the grid of the net body 3. An airbag 8 is connected between the upper blocking curtain block 6 and the lower blocking curtain block 7. Directional vesicles (not shown in the figure) are provided on both sides of the airbag 8 close to the upper blocking curtain block 6 and the lower blocking curtain block 7. The plurality of first wire netting bones 1 and the plurality of second wire netting bones 2 are all provided with air ducts 9. The air outlet ends of the air ducts 9 are connected to the corresponding airbags 8 and directional vesicles, and the air inlet ends of the air ducts 9 are connected to an external air pump.

[0022] Specifically, a net body 3 is formed by arranging a plurality of first wire netting bones 1 and second wire netting bones 2 distributed in a crisscross manner. Among them, mesh holes are formed between the first wire netting bones 1 and the second wire netting bones 2. Upper blocking curtain blocks 6 and lower blocking curtain blocks 7 are connected to the upper and lower sides of the intersection of the first wire netting bone 1 and the second wire netting bone 1. The area of the blocking curtain block is smaller than the area of the mesh hole, and an airbag 8 is fixedly arranged inside the upper blocking curtain block 6 and the lower blocking curtain block 7, so that the airbag 8 is located between the two blocking curtain blocks. Also, since air ducts 9 are arranged inside the first wire netting bones 1 and the second wire netting bones 2, the input ends of the air ducts 9 are connected to an external air pump, and the output ends of the air ducts are connected to a plurality of airbags 8. The external air pump can be turned on to supply air into the airbags. In this way, when constructing at night, the air pump can supply air into the airbags to make the airbags inflate and expand, blocking the entire mesh hole. At this time, the light inside the safety net will not be transmitted to the outside through the airbag, achieving a good light isolation effect and avoiding light pollution.

[0023] Specifically, a noise reduction layer 10 is provided on the outer sides of the upper shielding curtain block 6 and the lower shielding curtain block 7. The noise reduction layer 10 is a foam layer or a sponge layer. The noise reduction layer 10 is provided on the outer side surfaces of the upper shielding curtain block 6 and the lower shielding curtain block 7, and the noise reduction layer 10 is fixedly connected to the shielding curtain block. The noise reduction layer 10 is a foam layer or a sponge layer. In this way, the shielding curtain block outside the airbag 8 can not only protect the airbag itself, but also rely on the outer noise reduction layer to achieve the effect of sound insulation and noise reduction, so as to reduce the propagation of noise generated during construction and reduce noise pollution.

[0024] Specifically, the first wire netting bone 1 and the second wire netting bone 2 are hollow pipelines formed by nylon fiber weaving, which can provide good tensile strength.

[0025] Specifically, the upper shielding curtain block 6 and the lower shielding curtain block 7 are located at a corner of the mesh hole, and the shielding curtain block is fixedly connected to the protection net body. A plurality of directional vesicles are provided on one side of the airbag 8 close to the mesh hole. The directional vesicles are communicated with the airbag 8 and the air duct 9, and are used to cover the mesh hole in the inflated state. In this way, when the airbag is in the non-inflated state, the airbag contracts inside the shielding curtain block and is protected by the shielding curtain block, and the mesh hole can maintain a good ventilation state, avoiding poor ventilation inside the protection net. When the airbag is inflated, the directional vesicles will expand along the preset direction to cover the entire mesh hole, so as to achieve the effect of isolating light and avoiding light pollution. The shielding curtain block occupies 3 / 5 - 4 / 5 of the area of the mesh hole. In this way, the mesh hole can maintain a good ventilation state when the airbag is in the non-inflated state.

[0026] During use, multiple protection nets are spliced together so that the pulling ropes 4 of the protection net body partially overlap with each other, and then the positioning rings 5 are fixed on the scaffolding to avoid leaving empty parts, forming a large protection net. Among them, the protection net body includes a number of first wire netting bones 1 and second wire netting bones 2 that are distributed vertically and horizontally. Mesh holes are formed between the first wire netting bones 1 and the second wire netting bones 2. Both the first wire netting bones 1 and the second wire netting bones 2 are hollow pipelines formed by nylon fiber weaving, and the air duct 9 is installed inside them, and they can provide good tensile strength. When constructing at night, the air pump can supply air to the inside of the airbag 8. When the airbag 8 is inflated, the directional vesicles will expand along the preset direction to cover the entire mesh hole. At this time, the light inside the protection net will not be transmitted to the outside through the airbag, achieving a good light isolation effect and avoiding light pollution. At the same time, a noise reduction layer 10 is provided on the outer side surfaces of the upper shielding curtain block 6 and the lower shielding curtain block 7. The noise reduction layer 10 includes a foam layer or a sponge layer. In this way, the shielding curtain block outside the airbag can not only protect the airbag itself, but also rely on the outer noise reduction layer to achieve the effect of sound insulation and noise reduction, so as to reduce the propagation of noise generated during construction and reduce noise pollution.

[0027] This building engineering protection net is provided with shielding curtain blocks inside the mesh holes of the protection net, and inflatable airbags are arranged on the inner sides of the shielding curtain blocks. When constructing at night, an air pump can be used to supply air into the airbags, causing the airbags to expand and cover the entire mesh hole, achieving a good light isolation effect and avoiding light pollution. At the same time, a noise reduction layer is provided on the outer side surface of the shielding curtain block, achieving a sound insulation and noise reduction effect to reduce the propagation of noise generated during construction and reduce noise pollution.
