Example one
As shown in fig. 1-5, the present invention provides a double-spliced steel foundation, which includes a plurality of foundation units disposed between two structural beams (shown as a first structural beam 1 and a second structural beam 2), wherein each foundation unit includes at least one steel section 32, each steel section 32 is fixedly connected to a bottom plate 34, the bottom plate 34 is mechanically connected to the structural beams, a concrete reversed sill 9 is disposed around the double-spliced steel foundation, a masonry structure 6 is disposed on the reversed sill 9, and waterproof structures 9 are disposed at the joints of the concrete reversed sill 9 and the structural beams and on the surfaces of the structural beams.
The plurality of base units in this embodiment are connected to each other by a top plate 31.
The masonry structure 6 surface in this embodiment is also covered with SBS waterproofing membrane 92.
The joint of the SBS waterproof roll 92 and the section steel 32 in the embodiment is provided with a sealing rubber strip for sealing.
The bottom plate 34 in this embodiment is welded to the construction beam.
Example two
As shown in fig. 6, when the double-spliced steel foundation passes through the boundary of the cantilever plate, the waterproofing treatment as shown in fig. 6 is required. Set up waterproof construction 9 in basic and board junction of encorbelmenting, waterproof construction 9 is from supreme cement mortar screed-coat 94, extruded sheet 93, SBS waterproofing membrane 92 and cement mortar protective layer 91 of having set gradually down. A floor drain 95 is provided on the cantilever plate at the junction for drainage. A water draining groove 73 is hung and installed on the inner side, close to the foundation, of the joint of the foundation and the cantilever plate through a hanging rod 71, one side of the water draining groove 73 is hung and installed above the foundation through the hanging rod 71, the other side of the water draining groove 73 is connected to the cantilever plate through a mechanical structure (including but not limited to rivets and screws), and a rubber pad is arranged at the joint of the foundation and the cantilever plate and used for sealing and waterproofing.
