Abstract
A light steel keel connecting structure, comprising at least two light steel keels, each of which has a connecting surface connecting with the other light steel keel, and connecting pieces for connecting the light steel keels, characterized in that concaves are provided on each of the connecting surfaces respectively which are depressed toward inside of the light steel keels, and the concaves of two connecting surfaces which are connected vertically are disposed by way of embedding, and at least two connecting holes are provided at corresponding positions of two concaves that are embedded, respectively, and the connecting pieces are provided within the connecting holes in a state of connection. The terminals of the connecting pieces at one end where depression sides of the concaves are located do not go beyond outer edges of the openings of the concaves on the same side as the terminals of the connecting pieces. At the junction of the light steel keel connecting structure of the invention, there is provided, a concave structure, for which, a mechanized mass production can be implemented very easily. The positioning is extremely easy during assembling, because concave structures of upper and lower connecting surfaces are engaged with each other. Strength of connection and rigidity of light steel keels are greatly improved. Top surfaces of connecting pieces can be wholly submerged in the concave, and accordingly, they will not cause interference to other connecting components on surfaces of the light steel keels.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
