Connecting joint for modular building and modular building

Abstract

The invention provides a connecting joint for a modular building and the modular building. The connecting joint comprises upper layer columns, lower layer columns and a middle connecting column, a lower inserting hole is formed in a lower layer column, a lower protrusion is arranged at the lower end of the middle connecting column, and a lower spiral groove is formed in the hole wall of the lower inserting hole so that the lower protrusion can enter the lower spiral groove; and a lower groove is formed in the lower end of the lower spiral groove so that the lower protrusion can be embedded into the lower groove to be matched with the lower layer column in a rotation stopping mode in the circumferential direction. A clamping piece is arranged in a gap between an upper layer column and the lower layer column. According to the connecting joint for the modular building and the modular building, the middle connecting column is connected with the lower layer column and the upper layer column in a screwing and inserting mode, when the middle connecting column is connected with the lower layer column, the middle connecting column and the lower layer column can be automatically screwed and locked only through gravity, and compared with traditional welding and bolt connection, the construction speed is higher. Meanwhile, the cross section area of the middle connecting column is larger than that of a traditional connecting piece, and better horizontal load resistance is achieved. In addition, upper springs are arranged in the upper layer columns, lower springs are arranged in the lower layer columns, and elastic clamping pieces are arranged between the upper layer columns and the lower layer columns, so that the anti-seismic performance of the modular building is greatly improved.

Description

technical field [0001] The invention relates to the technical field of modular buildings, in particular to a connection node for modular buildings and a modular building. Background technique [0002] At present, my country's construction industry is vigorously promoting the use of prefabricated buildings. Steel structure buildings are the mainstream direction in prefabricated buildings. Steel structure modular buildings are a hot spot and emerging research direction in steel structure buildings. Modular building is a building that divides traditional houses into individual modules according to specific functions, pre-fabricated in factories, shipped to the construction site by means of transportation, and assembled and installed on site. Modular buildings have a short production cycle, fast construction speed, high construction quality and environmental protection, which is a structural model with great potential for future development. [0003] In modular buildings, there...
