Connecting device and method for cast-in-situ concrete column and load-bearing wooden beam

Abstract

The invention relates to the field of civil engineering, in particular to a connecting device and method for a cast-in-situ concrete column and a load-bearing wooden beam. The invention provides a connecting device for a cast-in-place concrete column and a load-bearing wooden beam, including a vertical plate with pre-embedded reinforcement, a supporting plate connected to the lower part of the vertical plate and a tenon plate located between the vertical plate and the supporting plate. The vertical plate, the supporting plate and the tenon plate are perpendicular to each other. The supportingplate is used to support the wooden beam, the tenon plate is fixed with middle parts of the vertical plate and the supporting plate, and the tenon plate is used to match a tenon groove of the wooden beam. In the connecting device and method for a cast-in-situ concrete column and a load-bearing wooden beam, the supporting plate and the tenon plate can guarantee the installation position of the wooden beam. In installation, the wooden beam can be lowered and installed quickly when the tenon groove is aligned with the tenon plate. A connecting plate and the wooden beam can be connected and fixedafter being lifted. The connecting device and method for cast-in-situ concrete column and load-bearing wooden beam has the advantages that a few lifting tables are needed, the connecting plate can increase the bearing capacity and bending resistance of the supporting plate, and the connecting device can firmly connect and fix the wooden beam to the cast-in-situ concrete column.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a connection device and method for a cast-in-place concrete column and a load-bearing wooden beam. Background technique [0002] In recent years, the combined structure of concrete structure and wood structure has been used more and more in the fields of civil engineering, antique buildings, and ancient building maintenance. When wooden beams and concrete columns are connected, the safety and applicability of the connection of different materials has become a A problem that cannot be ignored. [0003] The traditional way of connecting wood and stone is to use nails or pre-embedded expansion screws. The connection strength is limited. In this case, most of the wooden beams do not bear load and only play a supporting or decorative role. A connection method that is safer and meets the design rigidity, strength and stability requirements. Contents of the invention [0004] In ord...
