Connecting piece for enhancing bearing capacity of tool type scaffold and installing method of connecting piece

The invention discloses a connecting piece for enhancing the bearing capacity of a tool type scaffold and an installing method of the connecting piece. The connecting piece comprises lower adjusting lead screw bases, a base fixing plate and an upper fixing connecting piece body. Lead screws of the four lower adjusting lead screw bases are sleeved with the base fixing plate and sleeved with the lower portions of four adjacent stand columns of the tool type scaffold respectively. The upper fixing connecting piece body comprises a bearing top plate, outer sleeves, inner sleeves, a limiting plate and upper connecting bolts. The upper portions of the four adjacent stand columns of the tool type scaffold are inserted in the four outer sleeves of the upper fixing connecting piece body respectively to abut against the limiting plate. When some frame bodies with heights needing to be adjusted and high bearing requirements are erected, by means of the connecting piece, the bearing capacity of the tool type scaffold can be greatly improved, the rigidity and stability required by the tool type scaffold can be achieved, and the connecting piece is easy, convenient and flexible to use and operate and suitable for erecting platforms with large loads and high precision requirements.
