Corner joint piece of box-type building and building using method used for box-type building

The invention provides a corner joint piece of a box-type building and a building using method used for the box-type building. The corner joint piece comprises a corner joint piece body. The corner joint piece body comprises two clamping pieces and corner joint blocks. The clamping pieces are F-shaped boards and form a clamping groove structure. Transverse bolt hole structures are arranged at the two ends of each clamping piece correspondingly, and bolt hole structures are arranged on corner joint block structures matched with the clamping pieces. The corner joint blocks extend downwards and form second clamping faces. Bolt holes are connected through the bolt structures. Through the building using method of the box-type building, the box-type building is effectively made to be convenient to mount and detach rapidly, the overall structure is further reinforced and stabilized, and the box-type building can be further applied and popularized. 本发明提供种箱式建筑的角接件及其用于箱式建筑的建筑使用方法，包括角接件本体，所述角接件本体包括两块卡接件和角接块组成，所述的卡接件为F型材
