Novel fabricated building connecting piece

Abstract

The invention discloses a novel fabricated building connecting piece comprising a hollow inner edge sleeve I, a hollow inner edge sleeve II and a right-hand and left-hand thread lead screw. A fixing nut and a locking nut are arranged in the bonding position of a right-hand thread and a left-hand thread; circular holes allowing the right-hand and left-hand thread lead screw to pass are formed in one ends of the hollow inner edge sleeve I and the hollow inner edge sleeve II correspondingly; a right-hand thread outer edge nut clamped with an inner edge hollow is installed in the hollow of the hollow inner edge sleeve I, and a left-hand thread outer edge nut clamped with an inner edge hollow is installed in the hollow of the hollow inner edge sleeve II; and one end of the right-hand and left-hand thread lead screw penetrates through the circular hole of the hollow inner edge sleeve I to be connected with the right-hand thread outer edge nut in a screwed mode, and the other end of the right-hand and left-hand thread lead screw penetrates through the circular hole of the hollow inner edge sleeve II to be connected with the left-hand thread outer edge nut in a screwed mode. The connecting problem of building members is well solved, steel bars in the members are directly connected, the structure is simple, and connecting and locking are convenient.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a novel prefabricated building connector. Background technique [0002] At present, in the field of prefabricated building technology, the connection mode between building components has been restricting the development of prefabricated buildings. At present, the connection between building components, especially the PC building component system, generally adopts reserved steel bars, sleeve connections, on-site pouring and on-site grouting. These connection methods have many reserved steel bars, large deformation during production and transportation, and difficult on-site docking. The construction process is complex, difficult to disassemble, and difficult to popularize. Some reserved mounting holes are used to connect one component to another component through bolts, but the mounting holes are often not well combined with the component, resulting in ...

Problems solved by technology

At present, the connection between building components, especially the PC building component system, generally adopts reserved steel bars, sleeve connections, on-site pouring and on-site grouting. These connection methods have many reserved steel bars, large deformation during production and transportation, and difficult on-site docking. The construction process is complex, not easy to disassemble, and difficult to promote

Some mounting holes are reserved to connect one component to another component through bolts, but the parts of the mounting holes are often not well combined with the components, resulting in insufficient tension and strength, causing cracks and damage around the holes
