Embodiment Construction
[0022] Refer to the attached Figure 3-4 The technical solution of the present invention is described in detail.
[0023] The construction method of the steel pipe column ring beam beam column joint is as follows:
[0024] First, according to the design requirements, a plurality of beam main ribs 21 are normally welded on the upper and lower ring plates 22 of the steel pipe column ring beam at the steel pipe column 20 ring beam beam-column joint. The length meets the requirements of the code, and then the beam bottom formwork support frame is supported.
[0025] Next, install the steel pipe column ring beam up and down annular steel bar 23 that the diameter of multiple circles increases gradually around the steel pipe column, and the annular steel bar 23 is all fixedly arranged on the upper and lower ring plates. 23. At the same time, a plurality of first stirrups 24 and a plurality of first pull hooks 25 are threaded through reserved hole positions (not shown in the figure)...

The invention discloses a construction method for steel pipe column ring beam column nodes. The steel pipe column ring beam column node structure comprises a steel pipe column, upper and lower annular plates which are arranged vertical to the steel pipe column, and a plurality of beam main reinforcements which are arranged vertical to the steel pipe column and welded on the upper and lower annular plates, wherein a plurality of rings of annular steel bars are arranged surrounding the steel pipe column; the annular steel bars are fixedly arranged on the upper and lower annular plates; a plurality of stirrups are fixedly inserted into the upper and lower annular plates; a plurality of hooks and waist bars are bundled on the stirrups; a plurality of oblique haunched steel bars are arranged on outer rings of the annular steel bars; and the oblique haunched steel bars are inserted into adjacent beams.
Description
technical field [0001] The invention relates to a joint structure in building structure engineering, in particular to a steel pipe column ring beam beam column joint structure. Background technique [0002] In building structure engineering, the construction of steel pipe column ring beam beam column joints is generally based on the design shape and size, the main reinforcement of the surrounding beams is welded to the steel pipe column ring beam ring plate, and then the ring steel bars with gradually increasing diameter are welded on the steel pipe column ring. The upper and lower ring plates of the beam are installed around the steel pipe column, and are mechanically connected or welded and closed. [0003] See figure 1 and figure 2 , are respectively the plan view and cross-sectional view of the existing steel pipe column ring beam beam-column joint. The common construction method of this joint structure is, according to the design shape and size, around the steel pipe...
