Method for assembling a wind turbine blade, wind turbine blade cleat for assembling a wind turbine blade shell and clamp tool for clamping a separately manufactured glue flange during assembly of a wind turbine blade

A method for assembling an integrated wind turbine blade shell, the method comprising the steps of:

• providing:
• a first and a second wind turbine shell part each extending along a longitudinal direction and each having an interior surface configured for facing the interior of the wind turbine blade, the first wind turbine blade shell part comprising a first edge and the second wind turbine blade shell part comprising a second edge,
• a glue flange extending along the longitudinal direction and having an upper edge, a lower edge, an interior surface configured for facing the interior of the wind turbine blade, and an exterior surface configured for facing the exterior of the wind turbine blade,
• a plurality of wind turbine blade cleats each including a base surface, an anchor positioned at a distance from the base surface, a ledge surface extending transversely to the base surface, and a rail protruding from the ledge surface, and
• a plurality of clamp tools each including a clamp head and an actuator configured for actuating the clamp head between an open position and a clamping position;
• attaching the plurality of wind turbine blade cleats including first cleats onto the interior surface of the first wind turbine blade shell part, the first cleats being positioned at a distance from the first edge of the first wind turbine blade part and being distributed along the longitudinal direction, wherein the ledge surface and the rail of each first cleat defines, together with the interior surface of the first wind turbine blade shell part, a ledge for supporting the glue flange;
• securing each clamp tool of the plurality of clamp tools to the anchor of each corresponding cleat of the plurality of attached cleats;
• resting the lower edge of the glue flange on the ledge surface of each first cleat so that the upper edge of the glue flange extends above the first edge of the first wind turbine blade shell part;
• closing the first and second wind turbine blade shell parts by bringing the first edge of the first wind turbine blade shell part and the second edge of the second wind turbine blade shell part together;
• actuate the plurality of clamp tools to clamp the glue flange between the clamp head of each clamp tool and interior surface of the first and second wind turbine blade shell parts so that a first adhesive contacts the exterior surface of the glue flange and the interior surface of the first wind turbine blade shell part and so that a second adhesive contacts the exterior surface of the glue flange and the interior surface of the second wind turbine blade shell part;
• and
• causing or letting the first adhesive and second adhesive harden to integrate the first wind turbine blade shell and second wind turbine blade shell part via the glue flange so as to assemble the integrated wind turbine blade shell.
