Assembled structure system and applications thereof

An assembled structure system, comprising a prefabricated member, at least one fastener, and a locking member, wherein

• the prefabricated member is provided with at least one cavity;
• the at least one fastener is assembled in each cavity of the at least one cavity;
• the each cavity comprises an upper end surface, a lower end surface, a left end surface, and a right end surface;
• wherein
• the upper end surface is provided with a fastener through hole or a locking member through hole, wherein the at least one fastener passes through the fastener through hole, and the locking member passes through the locking member through hole;
• each of the left end surface and the right end surface comprises a vertical surface and an inclined surface, wherein the vertical surface is perpendicularly connected to the upper end surface and the inclined surface is connected to the vertical surface;
• wherein
• a connection angle between the vertical surface and an outer side of the inclined surface forms an obtuse angle;
• the inclined surface of each of the left end surface and the right end surface is connected to the lower end surface;
• the upper end surface is located at an upper end or a lower end of the vertical surface, or located between the upper end and the lower end of the vertical surface;
• and
• the at least one fastener comprises a fixed surface, two side surfaces, and a bottom surface;
• wherein
• the fixed surface is provided with at least one locking hole or at least one through hole;
• the bottom surface is a curved surface, an arc surface, a fold-line surface, or a trapezoidal surface;
• a total width of the bottom surface is greater than or equal to a width of the fixed surface, and the total width of the bottom surface is greater than or equal to a width of the lower end surface;
• the bottom surface is formed by two inclined bottom surfaces, wherein the two inclined bottom surfaces are folded inwardly;
• a total width of the two inclined bottom surfaces is greater than or equal to the width of the fixed surface, and the total width of the two inclined bottom surfaces is greater than or equal to the width of the lower end surface;
• a height of the at least one fastener is higher than a height of the inclined surface;
• the at least one fastener has a flexibleness in connection portions between the fixed surface and the two side surfaces, and connection portions between the two side surfaces and the bottom surface;
• the fixed surface and the two side surfaces are hingedly connected, and the two side surfaces and the bottom surface are hingedly connected.
