Anti-pulling embedded-type gate-type steel frame steel-joint column foot and construction method thereof

Abstract

The invention discloses an anti-pulling embedded-type gate-type steel frame steel-joint column foot and a construction method thereof. The anti-pulling embedded-type gate-type steel frame steel-joint column foot is characterized in that a basic short column (1) is composed of injecting concrete, wherein a local-pressure-proof rebar net chip (2) is arranged on the top of the basic short column (1), a basic reverse cup-shaped hole (3) is formed inside the basic short column (1), the lower section of a steel column (8) is inserted into the basic reverse cup-shaped hole (3), a steel column base plate (4) is welded on the bottom of the steel column (8), a steel column toggle pin (5) is welded in the range of the height of the lower section of the steel column (8), a horizontal stiffening plate (6) is welded on the lower section, at the position of 100mm below the top of the basic short column (1), of the steel column (8), and the basic short column (1) is combined with the steel column (8) by the fact that cement mortars are injected in the basic reverse cup-shaped hole (3). According to the structure of the anti-pulling embedded-type gate-type steel frame steel-joint column foot, foundation bolts do not need to be arranged, the dimensions of the basic short column are small, structure is simple, steel materials are saved, and using is safe and reliable.

Description

Technical field [0001] The invention relates to an anti-pulling embedded portal rigid frame rigid connection column foot and a construction method. Background technique [0002] The portal frame structure is mostly used in single-story industrial or civil buildings such as factories, warehouses, stations, supermarkets, etc. Its characteristics are light weight, simple construction, and good seismic performance, so it is widely used. The column legs of the portal frame are generally connected by hinges. When the frame span is large and the load is large, the column legs are rigidly connected, so that the rigid frame beams and columns can bear reasonable stress and achieve the purpose of saving steel. At present, the commonly used rigid frame rigid frame with stiffening ribs are composed of anchor bolts, shear parts, steel column foot bottom plate, and column foot stiffening plates. This kind of column foot needs to reserve foundation bolts on the foundation short column. The bend...
