View Patent ↗A doorway lintel lift apparatus and method are provided. The door lintel lift apparatus may include two support columns, a lintel that is configured to be attached to the support columns, and that includes a vertical flange and a horizontal flange. The apparatus may include two lift bolts coupled to two end portions of the horizontal flange. The two lift bolts may be configured to respectively raise the two end portions of the horizontal flange. The apparatus may include two rotatable lift nuts that, when rotated, raise the lift bolts to engage and raise the two ends of the horizontal flange.
1. A method of lifting a doorway lintel, the method comprising:
affixing two support columns to an existing structure;
affixing a lintel comprising a vertical flange and a horizontal flange to the two support columns; and
rotating at least one lift nut, thereby raising at least one lift bolt to contact and raise at least one end of said horizontal flange;
wherein the horizontal flange is arched so that the two end portions of the horizontal flange are below a center portion of the horizontal flange.
2. The method of claim 1 , wherein the two end portions of the horizontal flange each include an aperture configured to receive a lift bolt.
3. The method of claim 2 , wherein the at least one lift nut is disposed in one of the two support columns, such that rotating the at least one lift nut raises the at least one lift bolt through the aperture in the horizontal flange.
4. The method of claim 1 , wherein the rotating comprises rotating two lift nuts, thereby raising two lift bolts to contact and raise the two end portions of the horizontal flange.
5. The method of claim 1 , wherein the vertical flange is arched convexly to form a cambered angle.
