Embodiment Construction
[0034] The present invention is described in detail with reference to accompanying drawing:
[0035] like Figure 1 to Figure 6 As shown, a built-in X-shaped double-tensioned steel plate type welded rectangular steel tube concrete column, which includes welded rectangular steel pipe 1, X-type double-tensioned steel plate 2 and core concrete 7; Pouring core concrete 7 in the space.
[0036] The welded rectangular steel pipe 1 is a steel pipe with a rectangular cross section welded by four steel plates.
[0037] The X-shaped double-drawn steel plate 2 is a steel structural member with an X-shaped cross-section welded by a main steel plate 3 and two auxiliary steel plates 4; the device includes two X-shaped double-drawn steel plates 2, and the height is longitudinally welded rectangular steel pipes 1 / 4 of the net height of the concrete column is set at both ends of the column respectively; the shear bearing capacity at both ends of the column is strengthened, and the circular h...

The invention discloses a built-in X-shaped opposite-pulling steel plate type welded rectangular concrete filled steel tubular column and a construction method. The built-in X-shaped opposite-pulling steel plate type welded rectangular concrete filled steel tubular column comprises a welded rectangular steel pipe and X-shaped opposite-pulling steel plates; the X-shaped opposite-pulling steel plates welded to the corners of the welded rectangular steel pipe are arranged at the diagonal line positions of the welded rectangular steel pipe; the two X-shaped opposite-pulling steel plates are arranged at the two ends of the welded rectangular steel pipe correspondingly; each X-shaped opposite-pulling steel plate is formed by crossing a main steel plate and two auxiliary steel plates in an X shape and welding longitudinal welding lines of the X-shaped opposite-pulling steel plate; and concrete is poured into the structure formed by assembling the welded rectangular steel pipe and the X-shaped opposite-pulling steel plates. The core concrete is effectively divided through the X-shaped opposite-pulling steel plates, so that the constraint capacity of the welded rectangular steel pipe to the core concrete is improved, and the interface bonding slip performance of the welded rectangular concrete filled steel tubular column is improved advantageously; and accordingly, the bonding strength and the overall bearing capacity of the welded rectangular concrete filled steel tubular column are remarkably improved, and steel and concrete materials are saved.
Description
technical field [0001] The invention relates to a building component in a building structure and a construction method thereof, in particular to a built-in X-shaped opposite-drawing steel plate type welded rectangular steel pipe concrete column and a construction method thereof. Background technique [0002] Concrete filled steel pipe refers to the structural member in which concrete is filled in the steel pipe, and the steel pipe and its core concrete bear the external load together. Compared with reinforced concrete columns, in concrete-filled steel tube columns, the confinement effect of the steel tube on the concrete inside makes the concrete in a three-dimensional compression state, which improves the compressive strength of the concrete, and the concrete inside the steel tube can effectively prevent local buckling of the steel tube , The interaction between the steel pipe and the concrete makes the damage of the concrete inside the steel pipe change from brittle failur...
