Auxiliary vibrating framework of stiff structural column and construction method based on framework

Abstract

The invention discloses an auxiliary vibrating framework of a stiff structural column and a construction method based on the framework. The auxiliary vibrating framework comprises a vibrating rod, middle structural steel and at least one group of stirrups, and further comprises four groups of vertical steel bar groups, wherein the vertical steel bar groups are arranged close to four corners of the middle structural steel respectively; each vertical steel bar group comprises three vertical component steel bars and a net-shaped steel bar guide pipe; the three vertical component steel bars are arranged around the net-shaped steel bar guide pipe and are in contact connection; the plurality of stirrups are wound on the outer sides of the four vertical steel bar groups to form square structural ribs and are hooped at the periphery of the middle structural steel; at least one shear transmission pin is further arranged on an outer side wall of the middle structural steel; the shear transmission pins and vertical positions of the corresponding stirrups are arranged in a staggered manner; and the vibrating rod stretches into the net-shaped steel bar guide pipe from the top of the net-shaped steel bar guide pipe. According to the auxiliary vibrating framework disclosed by the invention, the vibrating rod can conveniently stretch into bottom concrete to be vibrated, so that the problems that the vibration is not dense and not uniform are avoided and the construction quality is improved. The construction method based on the framework is simple and practical.

Description

technical field [0001] The invention relates to the field of construction and construction, in particular to a stiff structural column assisted vibrating structure and a construction method based on the structure. Background technique [0002] There are a large number of shear nails welded on the outer side of the rigid steel column, and the shear nails and the steel bars on the outer side of the steel column cross each other, so that the distance between the shear nails and the steel bars is small. When ordinary concrete is used, the particle size of the concrete coarse aggregate is smaller Large, it is difficult to fall to the bottom of the column, and it is difficult for the vibrating rod to penetrate into the steel column. In many cases, it is difficult to penetrate into the bottom of the column, or even into the column. Due to quality problems such as holes, it is also difficult to pre-bury the vibrating opening with traditional construction methods. [0003] The previ...
