The lower safety vertical net hanging device of the frame beam comprises a lower nut 1, a lower bolt rod 2, a chain 3, a top plate 4, an upper nut 5, an upper bolt rod 6, a handle 7 and a connecting rod 8; two lower bolts 2 are arranged, each lower bolt 2 is screwed with two lower nuts 1, and the distance between the two lower nuts 1 is 100-200mm; the number of the upper bolts 6 is two, and the upper nuts 5 are screwed on the upper bolts 6; the lower end of the upper bolt rod 6 is welded with the top plate 4, and the upper end is welded with the handle 7; the upper ends of the four chains 3 are respectively welded on the outer sides of the two upper nuts 5, and the lower ends are respectively welded on the four lower nuts 1; the two ends of the connecting rod 8 are respectively welded with the two upper nuts 5.
The diameters of the lower nut 1 and the upper nut 5 are 30mm; the diameter of the lower bolt 2 and the upper bolt 6 is 30mm, and the lengths are 300mm and 800mm respectively.
The specification and model number of the chain 3 are 085-1-41, and the length is 1200mm.
The top plate 4 is a 20mm thick steel plate and is processed to be 100mm in size.
The handle 7 is a circular tube with the diameter of 25mm, and is processed and formed, and the length of the handle is 300mm.
The connecting rod 8 is a round tube with the diameter of 40mm, and is processed and formed, and the length of the connecting rod is 2000mm.
When the safety vertical net 10 is used, the hanging device is placed on the frame beam 9, a group of hanging devices is arranged every 3000mm, then the lower bolt 2 penetrates through the upper end of the safety vertical net 10, then the upper bolt 6 is screwed by the operating handle 7, the upper bolt 6 is pressed down, the upper nut 5 is lifted, the chain 3 is driven to lift upwards until the chain 3 is tightened, the safety vertical net 10 is straightened, and the safety vertical net 10 is normally used. When the safety vertical net 10 is loosened in the use process, the safety vertical net is adjusted by only screwing the upper bolt 6; after the frame structure is constructed, the safety vertical net 10 can be detached by loosening the upper bolt rod 6 and unscrewing the bolt rod 2, so that the safety vertical net is convenient and quick.
The utility model has the advantages that the hanging device is simple to assemble, convenient to operate and convenient to detach after use, can be conveniently adjusted in the use process, reduces the construction cost, and accumulates experience for similar construction in the future.
