Joint of concrete filled steel tubular column

Abstract

The invention discloses a joint of a concrete filled steel tubular column. The joint comprises an upper steel pipe column and a lower steel pipe column which are vertically arranged, a U-shaped steel beam is horizontally arranged on the side wall of the lower steel pipe column, an open groove is formed in the side wall of the lower steel pipe column and corresponds to the steel beam, the open groove extends downwards from the upper end of the lower steel pipe column, the two sides of the open groove respectively form a connecting end, one end of the steel beam penetrates through the open groove, extends into the lower steel pipe column and is fixedly connected with the lower steel pipe column; a connecting plate is vertically arranged in the steel beam, and the connecting plate is fixedly connected with the steel beam; and the lower end of the upper steel pipe column is fixedly connected with the upper end of the upper steel pipe column. According to the joint, the joint of the steel pipe column and the steel beam is reinforced from the inside through the connecting plate, so that the appearance of the junction of the steel pipe column and the steel beam is smooth; and a standardized component inner sleeving process is adopted, adopted components, the steel pipe column and the steel beam can be installed in a factory, the production process and the installation process are convenient and fast, and a new thought is provided for the development direction of prefabricated buildings.

Description

technical field [0001] The invention relates to the technical field of prefabricated building structures, in particular to a node of a steel tube concrete column. Background technique [0002] The industrialization of construction has always been the development direction advocated by our country and the fundamental way to develop prefabricated buildings. Entering the new era, with the advancement of construction technology and the rapid development of information technology, it is possible to truly realize the industrialization of construction. Prefabricated buildings are buildings built with new industrialized construction methods. Prefabricated buildings can be divided into three categories according to their material forms: prefabricated prefabricated concrete structures, fabricated steel structures and fabricated wood structures. At present, my country is vigorously promoting the development of steel-structured prefabricated houses. Different structural forms and new no...

Problems solved by technology

[0004] In view of the above-mentioned deficiencies existing in the prior art, the object of the present invention is to provide a joint of a steel pipe concrete column to solve the problem of joints between a steel pipe column and a steel beam in the prior art. It is difficult to use short beams or steel corbels to connect the construction, the reinforcement members are located outside the joints to affect the appearance, and the human operation technology has a great impact on the construction quality.
