Assembly-type steel-wood combined beam column joint structure and construction method thereof

Abstract

Provided are an assembly-type steel-wood combined beam column joint structure and a construction method thereof. The joint structure comprises a steel-wood combination beam, a steel-wood combination column and a connector fixing the steel-wood combination beam and the steel-wood combination column. The steel-wood combination beam and the steel-wood combination column are vertical to each other. The steel-wood combination beam comprises an inverted T-shaped beam, left and right wood boards connected to two sides of an inverted T-shaped web board and a lower wood board connected to the bottom surface of an inverted T-shaped beam flange. The steel-wood combination column comprises an I-shaped column, wed wood boards connected between two flanges of the I-shaped column and front and back flange wood boards connected outside the two flanges of the I-shaped column. The connector comprises a bottom board and inserting boards connected to the right side of the bottom board. During construction, the inserting boards are inserted into inserting grooves of left and right wood boards in order to be fixedly connected with the steel-wood combination beam. The bottom board is fixedly connected tothe outer surface of the flange board of the steel-wood combination beam in order to achieve joint connection of a steel-wood combined beam column. Material stress characteristics of a steel-wood structure are fully leveraged in order to reduce self weight of the structure and save steel material. Due to design of joints, high operationality is obtained so that construction time is saved.

Description

technical field [0001] The invention relates to the field of beam-column node structures, in particular to an assembled steel-wood composite beam-column node structure and a construction method thereof. Background technique [0002] Today's buildings and structures are mostly constructed of concrete materials, but concrete materials have problems such as self-heavyness, poor seismic performance, and easy cracks. However, the use of steel structures, wood structures and other materials can effectively reduce the weight of materials and improve the overall seismic performance of buildings. , especially when the steel-wood composite structure is used, the material properties of high strength, light weight, good overall rigidity and strong deformation ability of the rigid structure can be fully utilized, and the characteristics of the wood structure such as good compression resistance and earthquake resistance can be used at the same time. In the steel-wood composite beam-column...

Problems solved by technology

In the steel-wood composite beam-column structure, the effective connection of the joints is an important measure to ensure its effective stress and bearing capacity. In the past, concrete poured joints were often used, but no corresponding joint design was proposed for the steel-wood composite beam-column structure. Therefore, it is necessary to Assembled steel-wood composite beam-column components, a node structure with strong operability and easy construction and its construction method are proposed
