Device, tool and method dedicated to replacement of back bolt type dry-hanging stone curtain wall units

Abstract

The invention provides a device, a tool and a method dedicated to the replacement of back bolt type dry-hanging stone curtain wall units. The device, the tool and the method dedicated to the replacement of back bolt type dry-hanging stone curtain wall units comprise a stone slab, a mounting bracket, a back bolt bracket, a cross groove screw, a nut sleeve, a U-shaped spring fastener, a silica gel cup, a fastener groove, silica gel notches, a fixing bolt hole, a spring fastener-fixing hole, an operation hole, a notch wrench and a cranked wrench. The device, the tool and the method dedicated to the replacement of back bolt type dry-hanging stone curtain wall units are characterized in that a hollow concrete drill is used for separating and removing an old stone slab, the nut sleeve is used for fixing a back bolt, the U-shaped spring fastener is used for fastening the cross groove screw, and a new stone slab is fixed by a silicone adhesive reinforcement method. Compared with the prior art, the device, the tool and the method dedicated to the replacement of back bolt type dry-hanging stone curtain wall units do not need to choose one side to sequentially remove and mount all stone slabs on the side, can separately take off slabs for windowing and repair an opening with a single slab, and has the remarkable advantages of simplicity in operation, high efficiency, time and labor saving, safety, reliability, less affection on surrounding stone slabs, less disturbance, low cost and the like, thus having high popularization and application valve.

Description

1. Technical field: [0001] The invention provides a back-tie type dry-hanging stone curtain wall unit replacement special device, tool and method, belonging to construction engineering. 2. Background technology: [0002] The back-bolt type dry-hanging stone curtain wall technology is widely used for its on-site assembly operation, fast progress, independent load-bearing of each plate, good loading and unloading, good wind resistance, earthquake resistance, material saving and environmental protection, and low cost. Various public buildings. However, due to the process characteristics of sequential assembly from top to bottom, from one side to the other, serious color difference occurs at non-edge positions. Accidentally damaged monomers affect the quality of the project. When they have to be replaced, they must be replaced from the near side in order. The continuous dismantling to the replacement position is not only a huge amount of work, but also more likely to cause dama...

However, due to the process characteristics of sequential assembly from top to bottom, from one side to the other, serious color difference occurs at non-edge positions. Accidentally damaged monomers affect the quality of the project. When they have to be replaced, they must be replaced from the near side in order. The continuous dismantling to the replacement position is not only a huge amount of work, but also more likely to cause damage, damage, and greater losses to adjacent plates
