Abstract

The invention discloses a single-rod square steel tube support with a casing and a manufacturing method thereof. The single-rod square steel tube support comprises horizontal axial symmetrical strip-shaped square steel tube supports, wherein a flared end plate is embedded into the two end parts of the square steel tube support respectively; the large opening end of each flared end plate is formed outside the square steel tube support; a reinforcing plate is fixed on the upper surface and the lower surface of the small opening end of each flared end plate respectively; and the outer surface of the square steel tube support is sleeved with a coaxial casing. By adopting the single-rod square steel tube support, the problems of low compression rigidity, small compression yield bearing force and early rupture deformation under the reciprocating pull pressure action existing in an ordinary single-rod steel support are solved, and the deformation capability of the support is ensured.

Description

technical field [0001] The invention belongs to the technical field of steel supports, and in particular relates to a single-rod square steel pipe support with casing and a construction method thereof. Background technique [0002] In recent years, single-bar steel braces have been widely used in engineering as lateral force-resistant structural members in multi-storey or high-rise buildings, especially factory buildings. However, ordinary single-bar steel braces are prone to buckling under compression, with low compressive bearing capacity, rapid attenuation of lateral stiffness after buckling, and large out-of-plane deformation after buckling, resulting in a prominent difference between the tensile and compressive properties of the brace. In the building, it is necessary to arrange multiple tensile supports along each design direction to compensate for the stiffness and bearing capacity of the original tension support after the horizontal load is reversed into compression ...
