Abstract

The existing building block structure generally depends on deformation characteristics of elastic materials (such as plastics) to realize shaft hole interference fit, so that building block parts must have elastic deformation capacity, and application of rigid materials such as metal, stone and the like is severely restricted. Meanwhile, the prior art has the contradiction of two poles of an assembly mode, namely if interference fit is adopted completely, the connection is stable, the disassembly is time-consuming, and if only clearance fit is adopted, the structure is loose and easy to deform. According to the application, an elastomer protection layer structure is introduced, and the end part of the rigid connecting rod piece is sleeved with the elastomer protection layer, so that the rigid material can realize interference fit on the premise of not depending on self deformation, and the material limit is effectively broken through. Meanwhile, a hybrid assembly mode is adopted, interference fit is adopted at a core connecting node (such as a positioning pore canal) to ensure stability, clearance fit is adopted at a non-core node (such as a through pore canal) to improve assembly efficiency, and therefore double requirements of efficient assembly and stable structure are cooperatively realized.
