Pack space on header to create a flush surface with the ledger and install joist hangers. Remove ledger, fill notch with packing, and install joist hangers Do the same with the header.Ĭ. To do this would I need to cut into the slab and then re-pour a thicker footer or is there a solution that would not involve modifying the slab/floor?ī. The concrete slab in the basement is 4" thick. Build a wall along the edge of the steps to support the header and ledger. It also returns the length of the ridge board, and the length and number of rafter ties and collar ties. Run beam across all 5 joists and use screw jacks to raise back to proper height level with the rest of the joists then:Ī. The Roof Rafter Count calculator computes the total number of rafter boards (roof joists) for a gabled roof based on the ridge length, pitch and span. Joist and Header size: 2.75"圆.75" on 16" centers, notched 3" The staircase from the 1st floor to 2nd floor is also right above this area, so it is probably contributing to the overloaded connections. The wall directly above shows no sign of recent movement (cracked plaster, molding separating ect) and there is no movement/creaking of the floor so it appears to be "stable" for now. The floor above has sunk in this location ~1/4" max. Collar ties or ridge straps to resist wind uplift shall be connected in the upper third of the attic space in accordance with Table R602.3(1). The header is about 5/8" below the floor on the "bottom" side of the stairs and about 1/8" on the "top" side of the staircase. Where ceiling joists or rafter ties are not provided, the ridge formed by these rafters shall be supported by a wall, beam, or girder constructed in accordance with this code. all 3 ledgers have separated from the supporting member significantly. 5 tail joists are attached to the header in the same manner. The majority of the floor joists are resting on the brick foundation and are in good shape, however around the opening for the stairs the header running along the opening is notched on each end and resting on a ledger nailed to the trimmer on either side. There are some issues with the floor joists in the basement. I recently moved into my first home, built in 1900, SE Pennsylvania.
