[0002] In engineering construction, in order to meet higher requirements for safe and civilized construction, places such as safety passages, water and electricity processing sheds, on-site warehouses, power distribution facilities, and mechanical equipment all have the need for enclosure and shielding. Tool-type protective sheds are all structural forms supported by square steel pipes as columns. When the columns are supported, the keel needs to be welded or fixed to the columns of the tool-type protective shed during the enclosure process. Then, steel mesh or corrugated iron is installed above the holes to achieve the purpose of enclosure.

At this time, the U-shaped sleeve plate 201 and the conical limiting block 208 are in contact through the contact slope 211. The connecting screw 203 and the locking nut 205 are connected by threads, so that the U-shaped sleeve plate 201 and the positioning groove plate 204 are locked and installed through the supporting rib plate 202, the connecting screw 203 and the locking nut 205. Then, under the limiting action of the conical limiting block 208, the U-shaped sleeve plate 201 and the positioning groove plate 204 are fixedly connected to the supporting column 101, so as to prevent the U-shaped sleeve plate 201 from sliding along the axis of the supporting column 101. Then, the two ends of the lateral keel steel pipe 103 are fixedly connected to the two connecting steel pipes 207 through the scaffold corner lock, which facilitates the rapid assembly of the shed keel.
