At present, the interconnection between walls is realized by connecting and fixing the traditional C-shaped steel keel with fasteners. When the traditional C-steel keel is connected with each other, due to the unreasonable design of C-steel keel structure, the use of fasteners is very inconvenient, and the help of connecting plate is needed, which makes the connection of the whole wall very difficult.
At the same time, due to the inconvenient connection between the walls, it is more unrealistic for the staff to install the internal and external walls first, and then connect the walls to the construction site without installing the internal and external walls. The disadvantage of this is that the installation of the internal and external walls on the construction site is not convenient It is not convenient to cut off the energy and waste the construction site.
The technical scheme adopted by the new type C steel keel group for wall connection is: a new type of C-shaped steel keel is used for wall connection, including main C-steel keel and auxiliary C-steel keel. The main C-shaped steel keel is composed of main panel, two side panels and two skirt plates, and the secondary C-shaped steel keel includes main panel, two skirt plates, wide side plate and narrow side plate.
The width of the main panel on the main C-shaped steel keel is larger than that of the narrow side plate on the auxiliary C-shaped steel keel, and less than the width of the wide side plate of the auxiliary C-shaped steel keel.
