Abstract: The present invention is a kind of joint structure in the aluminum window, and in particular is designed for the awning typed aluminum window. It is mainly to design an internally laid joint plate with a simple structure to joint the window frames together directly. It is different from the prior art that needs to add an additional externally laid and large sized joint plate to joint the adjacent window frames. It is not only achieve the purposes of the large scaled material saving and also have the outside appearance of the whole aluminum window become more concise and not too disordered.
