Modular structure and said modular structure's structural members made of composite material

A modular building which is built by joining composite structural members;

• and as structural member, whole of it is made of a composite material comprising at least one type of fiber and at least one type of resin, comprising:
• at least two floor pieces where each of the pieces comprises at least one connection recess on at least one side and which are positioned with respect to each other where one of them corresponds to the connection recess of the other one and thus so as to define a connection housing;
• and a connection member which is placed to said connection housing,
• at least two wall adaptors which are placed onto the floor defined by said floor pieces and which comprise a body with at least one opening, at least one connection extension extending upwardly from said body and which comprise at least one connection recess provided on at least one lateral surface of the body and accordingly, which are positioned side by side so as to define a connection housing and where one of them corresponds to the connection recess of the other one;
• and a connection member which is placed to said connection housing,
• at least one wall brick which has a body with at least one opening and which has at least one connection housing provided on the base of said body and which has a connection extension extending upwardly from the body and which is placed on said wall adaptor so that the connection extension thereof enters into said connection housing.
