[0002] An assembled building refers to a building structure in which a large number of on-site operation works in the traditional construction method are transferred to a factory. Steel structure fittings processed and manufactured in the factory are transported to the building construction site and assembled and installed on-site through a reliable connection method.

[0003] Known steel structure connectors include external connectors and hidden internal connectors. The characteristic of these connectors is that they must be connected to one surface of the steel structure. The external connectors are relatively large in volume and mostly in the shape of a vertical bend. The connection contact surface is small, and the stability is insufficient, which easily causes the entire steel structure framework to be skewed. When connecting to the surface of the profile, screwing the screw may cause the entire profile framework to be skewed because the connector is not placed correctly; while the hidden internal connectors mostly adopt an insertion connection method and are fastened with screws on the outside. This connection method has the problem of insufficient strength. Content of the Utility Model

[0004] The purpose of the utility model is to provide a right-angle connector to solve the problems put forward in the above background art.
