Problems solved by technology

[0006] First, the connection method of beam-column joints is mostly welding, which is not conducive to the maintenance and repair of buildings and the replacement of components in the later stage;
[0007] Second, the connection method between the steel frame module units mostly refers to the connection method of the container module, but it is difficult to guarantee the strength and safety of the joints by ordinary bolting or welding;
[0008] Third, the combination form of modular building units is too single, it is only the accumulation of each unit in height, and there is a lack of structural innovation;

Abstract

The invention discloses a fabricated beam-column joint connecting device and application thereof, and belongs to the technical field of buildings and structural engineering. The beam-column joint connecting device comprises an inner sleeve and a connecting piece, wherein the connecting piece comprises an arc-shaped steel plate, H-shaped steel, a first connecting steel plate and a second connectingsteel plate; the H-shaped steel is connected with the protruding side of the arc-shaped steel plate; and a plurality of reserved holes are formed in the inner sleeve, the arc-shaped steel plate, a web of the H-shaped steel, the first connecting steel plate and the second connecting steel plate.

Description

technical field [0001] The invention relates to a prefabricated beam-column joint connection device and its application, belonging to the technical field of architecture and structural engineering. Background technique [0002] With the continuous development and exploration in the field of construction production in our country, the traditional cast-in-place structure is no longer in line with the green, environmental protection and sustainable development concept vigorously promoted by the country because of its rough production mode. Prefabricated buildings have already shined in the construction industry by virtue of their short construction period, high engineering quality, and low environmental pollution. The country has also issued a number of relevant policies to guide and promote the development of prefabricated buildings. [0003] Modular building is another extension on the basis of prefabricated building, which has a higher assembly rate. The prefabricated build...
