Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] First, see figure 1 and figure 2 As shown, a connection structure between a steel column and a concrete beam reinforcement in the present invention is mainly composed of a connecting corbel 11 , a reserved reinforcement 12 and a reinforcement connector 13 . The connecting corbel 11 corresponds to the concrete beam reinforcement and is fixed on the steel column 10, and the connection corbel 11 is provided with a reinforcement connection surface corresponding to the longitudinal reinforcement of the concrete beam reinforcement. A plurality of reserved reinforcement bars 12 are fixed on the connecting surface of the reinforcement bars, and the arrangement of the reserved reinforcement bars 12 corresponds to the arrangement of the longitudinal reinforcement bars of the concrete beam reinforcement on the plane, and each reserved r...

Abstract

The invention discloses a connecting structure and connecting method for a steel pillar and a concrete beam steel bar. The connecting structure comprises a connecting cow leg, a reserved steel bar and a steel bar connector used to connect a connection part and the concrete beam steel bar, wherein the connecting cow leg is fixed on the steel pillar; a steel bar connecting face corresponding to the concrete beam steel bar is disposed on the connecting cow leg; and the reserved steel bar is fixed on the steel bar connecting face and extends to one side of the concrete beam steel bar to form an overhanging section, and the connection part is disposed on the overhanging section. According to the invention, the reserved steel bar is disposed on the connecting cow leg during manufacture of the connecting cow leg, and then the connecting cow leg is welded to the steel pillar; and then, during connection of the concrete beam steel bar, the steel bar connector is installed on the connection part of an end part of the researched steel bar, and the steel bar connector is then used for connection of the concrete beam steel bar. In this way, direct welding of a threaded sleeve on the cow leg is avoided; and the problem that the steel bar cannot be screwed in due to threaded sleeve deformation caused by welding heat can be effectively solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a connection structure and connection method of a steel column and a concrete beam reinforcement. Background technique [0002] In the prior art, there are two connection processing technologies for the connection between the steel bar of the column-beam joint beam and the steel column in the reinforced concrete structure: ① welding with the steel column according to the anchorage length of the steel bar; These two methods have the following defects: the first method uses steel bars and steel columns to be directly welded, which increases the welding area, increases the hot brittle area of ​​the steel structure, and requires later reinforcement measures, which not only wastes materials, but also prolongs the construction period and increases material and labor costs. The second method of steel column drilling and piercing requires not only high processing precision, but also...
