Problems solved by technology

[0007] The main purpose of the present invention is to provide a double-sleeve splicing joint of outer square and inner circle steel pipes and its construction method. It is necessary to solve the inconvenience of on-site construction and operation, the complicated design and construction of the connecting components, and the joint connection method of the existing outer square and inner circle steel pipe core tube joints. Insufficient rigidity, and the problem of how to use sleeve splicing for the joint connection of the core tube at present; solve the technical problem of the structural collapse caused by the bolt breaking when the vertical load is too large

Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing.

[0040] Examples see Figure 1-3 As shown, a double-sleeve splicing joint of outer and inner circular steel pipes includes an upper square steel pipe column 1, a lower square steel pipe column 2, an upper round steel pipe column 3, and a lower round steel pipe column 4. The joint also includes square steel pipes connected to the upper section The square outer sleeve 6 between the column and the lower square steel pipe column, the circular inner sleeve 5 and the long bolt 7 connected between the upper round steel pipe column and the lower round steel pipe column.

[0041] Such as Figure 4 As shown, the four walls of the lower end of the upper square steel pipe column respectively have a row of at least two upper elongated hole grooves A8, and the four walls of the upper end of the square steel pipe column of the lower section respectively have a row of at least two lower el...

Abstract

The invention relates to the technical field of building steel structure construction, in particular to an outer-square and inner-circular steel pipe double-sleeve splicing joint and a construction method thereof. The outer-square and inner-circular steel pipe double-sleeve splicing joint comprises an upper-section square steel pipe column, a lower-section square steel pipe column, an upper-section circular steel pipe column and a lower-section circular steel pipe column. The square steel pipe columns comprise the upper-section square steel pipe column and the lower-section square steel pipe column, and the circular steel pipe columns comprise the upper-section circular steel pipe column and the lower-section circular steel pipe column. The joint further comprises a square outer sleeve connected between the upper-section square steel pipe column and the lower-section square steel pipe column, a circular inner sleeve connected between the upper-section circular steel pipe column and the lower-section circular steel pipe column and a long bolt. According to the outer-square and inner-circular steel pipe double-sleeve splicing joint and the construction method thereof, the problems that as for an existing outer-square and inner-circular steel pipe core cylinder joint connecting mode, on-site construction operation is inconvenient, connecting components are complex in design and construction, the rigidity of a joint is insufficient, and how a current core cylinder joint is spliced through sleeves is not determined are solved; and the technical problem that when the vertical load of a column is over large, a bolt fractures, and thus a structure collapses is solved.

Description

technical field [0001] The invention relates to the technical field of building steel structure construction, in particular to a double-sleeve splicing node and a construction method thereof. Background technique [0002] The comprehensive and industrialized transformation and upgrading of the construction industry is an inevitable trend of social and economic development. The Fifth Plenary Session of the 18th Central Committee also proposed the concept of "green" development. As a kind of green building, steel structure is in a period of vigorous development in the civil engineering industry. It is particularly important to quickly solve the key technologies of prefabricated steel structures, develop green high-performance new materials, and optimize and upgrade the form of building structures. The prefabricated steel structure is an important way for the development of building industrialization, and the connection of nodes occupies a very important position in the prefabr...
