Title: System of a set anchor with the stopper wall in the cantilever structure
Inventor: JANG YONG JAE
IPC: E04F13/08
Filed: 2021-03-23
Abstract: According to the present invention, a stop position of a front freestanding wall (100) playing a role of a rotation stopper is set at a position where tension (T) between a wedge anchor (WA) and the front freestanding wall (100) is not exerted to maintain the capability of the structure-allowed design value (Fca) of the wedge anchor (WA) as set for the first time to maximize the capability.

Abstract: When a system sends a request for authentication information to a cooperative agent application in an internal information system of an enterprise, the cooperative agent application analyzes the request, and delivers the request for authentication information to a corresponding server application of the internal information system after, if necessary, converting the same in an information format suitable for the internal information system of the enterprise by using an XML engine of the internal information system. Next, when the requested authentication information is received from the corresponding server application, the information is provided again to a business-to-business e-commerce system. Even before the delivery of the authentication information, the information format of the authentication information can be changed if necessary. The business-to-business e-commerce system which receives the authentication information, requests transaction information after authentication is completed, wherein the transaction information is also processed by the cooperative agent application similarly to the authentication information processing. Since the internal information system and the business-to-business e-commerce system can be connected using the cooperative agent application, companies which want to introduce business-to-business e-commerce can conduct business-to-business e-commerce with minimal cost and effort.
