Detailed Description
The present invention will be further described with reference to the drawings and examples, which should not be construed as a limitation to the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The embodiment is as follows:
as shown in fig. 1 to 8, a connection and reinforcement structure for an existing component and a newly added component includes an existing structural column 3, a newly added concrete corbel 2 and a newly added steel structure portion 4, the existing structural column 3 is connected with the newly added concrete corbel 2 through a column expansion portion 1, a part of the column expansion portion 1 is connected with the existing structural column 3 to form an integral structure, and the other part of the column expansion portion 1 is connected with the newly added concrete corbel 2 to form an integral structure.
Be equipped with built-in fitting 5 on newly-increased concrete corbel 2, newly-increased steel construction part 4 passes through support 8 and built-in fitting 5 welding. The force transmission path is clear, and the installation is simple. The joint of the support 8 and the embedded part 5 is provided with a stiffening rib 9, which not only improves the local bearing capacity of the structure and improves the local pressure stress of the joint, but also can be used as a gusset plate in the vertical connection direction.
