Embodiment Construction

[0023] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0024] In the preferred embodiment of the present invention, the main components involved include a circular tube body 1 , two through-boards 2 with the same shape and size, a rectangular inner partition 3 and an arc-shaped inner partition 4 . The two through plates 2 are parallel to the axis of the round pipe body and pass through the round pipe body 1. A rectangular inner partition 3 perpendicular to the round pipe body 1 is arranged between the two through plates 2. Between the two through plates 2 A curved inner partition 4 is arranged outside.

[0025] During the manufacturing process, the round pipe body 1 is first cut and disassembled into four arc-shaped tiles 11 , 12 , 13 , 14 in the middle, and special-shaped round pipe sections 15 , 16 at both ends. Wherein, when the round pipe body 1 is cut and disassembled, intersecting sl...

Abstract

The invention mainly discloses a round tube joint conversion structure and a manufacturing method thereof. According to a joint structure, a round tube is cut and divided into a plurality of arc tiles and irregular round tube sections, and the divided arc tiles, the irregular round tube sections and a penetrating plate are welded in a cross mode to obtain the round tube joint conversion structure. A horizontally-arranged rectangular inner partition plate is welded in the round tube joint conversion structure, an annular inner partition plate is arranged between the penetrating plate and the round tube, the annular inner partition plate, the penetrating plate and the round tube are welded in a cross mode through carbon dioxide shield welding or manual arc welding, and accordingly a rib plate, the penetrating plate and the round tube are integrally welded. On the premise without reducing structural safety, the round tube joint conversion structure solves the problems that an internal structure of a similar round tube conversion joint is difficult to achieve and the quality is difficult to guarantee. Meanwhile, the round tube joint conversion structure saves production cost.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a circular pipe joint conversion structure and a manufacturing method thereof. Background technique [0002] With the vigorous development of steel structures, steel structure buildings are also developing towards ultra-high and large trends, and higher requirements are also put forward in terms of processing and structural safety. For most super high-rise steel structure buildings, in order to obtain better structural safety and personnel safety protection measures, truss floors and refuge floors are often provided at certain positions. The circular tube joint transfer structure is widely used in building steel structures, and its types are relatively complex. The circular tube joint transfer structure is the key part connecting the core tube and the outer frame tube. Compared with conventional circular tube joints, in order to better transmit and balance the ...
