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 door lintel lift apparatus comprising:
two support columns configured to be affixed to an existing door structure;
a lintel comprising a vertical flange and a horizontal flange; and
two lift mechanisms respectively coupled to the two support columns and to two end portions of the horizontal flange, wherein the two lift mechanisms are configured to respectively raise the two end portions of the 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 door lintel lift apparatus of claim 1 , wherein the vertical flange is disposed at approximately a 90 degree angle to the horizontal flange.
3. The door lintel lift apparatus of claim 1 , wherein the vertical flange is arched convexly to form a cambered angle.
4. The door lintel lift apparatus of claim 1 , wherein the two end portions of the horizontal flange each include an aperture configured to engage one of the lift mechanisms.
5. The door lintel lift apparatus of claim 4 , wherein the two lift mechanisms each comprise a lift bolt;
wherein the door lintel lift apparatus further comprises two lift nuts; and
wherein the two lift nuts are disposed in the two support columns, respectively, and are configured to respectively receive the two lift bolts.
6. The door lintel lift apparatus of claim 5 , wherein the two lift nuts are configured to raise the respective lift bolts when the lift nuts are rotated, and thereby raise the respective two end portions of the horizontal flange.
7. The door lintel lift apparatus of claim 1 , wherein the two support columns are configured to be affixed to an existing structure or a floor.
8. The door lintel lift apparatus of claim 1 , further comprising a cover that is configured to be attached to one or more of the support columns, the lintel, and a corner where one of the support columns and the lintel are coupled.
