Embodiment 1
[0039]An anti-drop net for construction engineering, comprising more than two modular components 1 used in pairs, a nylon net 2 assembled between two adjacent modular components 1, and a nylon mesh fitted between two adjacent modular components 1 Lateral protective net 3;
[0040] The modular component 1 includes two front and rear main frame rods 101, the main frame rod 101 is equipped with a connecting steel plate 102, and a collision bolt 103 is matched between the connecting steel plate 102 and the building body, and the connecting steel plate 102 is far away from the side of the building body. One side is provided with a rotating seat 104, and a pin shaft 105 is fitted between the main frame rod 101 and the rotating seat 104, and the main frame rod 101 can rotate along the pin shaft 105, and the main frame rod 101 A diagonal brace 106 is welded near the connecting steel plate 102, the angle of inclination of the diagonal brace 106 relative to the main frame rod 101 is 30-...
Embodiment 2
[0043] On the surface of the nylon net 2, two side bars 211 are arranged parallel to each other. On the surface of the nylon net 2, a first side bar 212 is arranged between the side bars 211 on both sides. The first side bar 212 is perpendicular to the side bar 211, and the height of the first side bar 212 is lower than the height of the side bar 211, and the side bar 211 and the first side bar The cross-section of bar 212 is semicircular, and side bar 211 and first side bar 212 all adopt soft material; After the human body falls onto the protective net, the main frame rod 101 will compress the spring to buffer the body when falling. Impact force, reduce the damage to the nylon mesh. The adoption of the side bar 211 and the first side bar 212 makes the human body have barriers when rolling on the nylon net, reduces the body rolling after falling from the building, and reduces the secondary injury caused by rolling.
[0044] The soft material is rubber or latex.
Embodiment 3
[0046] A bottom buffer device 4 is assembled between the front and rear two main frame rods 101, and when the nylon mesh 2 deforms downward too much, it contacts the bottom buffer device 4, and the middle position of the bottom buffer device 4 can be downward Energy absorption after bending and collapse; when a person falls on a higher floor, the individual nylon net will collapse downward to a greater depth. Due to the greater depth of collapse, the human body will be bent to a greater extent on the nylon net. The occurrence of this bending is very easy to cause the fracture of the spine, leading to more serious consequences. After adopting the bottom buffer device, the bottom buffer device itself can absorb energy, and at the same time, it can also form a limit under the nylon mesh to avoid excessive deformation of the nylon mesh.
[0047] The bottom buffer device 4 includes a square tube 401, the two ends of the square tube 401 pass through the main frame rods 101 on both s...
