To build patio covers, the first steps are digging a 12-inch hole in each of the four corners of your patio. Place a 4 to 4 post anchor in each hole and fill the holes with pre-mixed cement. Let the cement cure overnight. Step two; attach a 4 to 4 post to each postanker. Drill a 5/8 inch hole through both sides of each post and insert 1/2 inch bolts to secure the anchor post.
Step three to build patio covers that detached, bore the same size holes at the top of each post. Attach a 4 to 4 post cap to each with 1/2-inch bolts. Step four; attach a 4 to 8 post from a post cap to the cap on the opposite side. Attach another 4 to 8 insert over the other side of the patio cover parallel to the first one. Drill 5/8 inch holes through the post and attach them to the casing with 1/2-inch bolts.
Step five, layout 2-to-6-by-12 foot rafter boards each 16 inches on the center, perpendicular to the beginning post. The ends of the beams rest on the 2 to 8 posts. Secure them with 16-penny nails hammered at an angle, two on each side to prevent twisting. Step six; cover the locks with 1-to-8 ship plywood. Place an 8-penny nail through the bearing in the rafter plates to hold them down. Place a nail every 12 inches. And the steps by steps of build patio covers that detached were done.
