Outer wall of basement reinforcing bar and junction steel plate are welded to connect；Overhanging buttress head reinforcing bar is connected with peg colligation；
Under the supporting of template, casting concrete on outer wall of basement reinforcing bar, overhanging buttress head reinforcing bar, shape all-in-one-piece ground
Lower room exterior wall and outwardly overhanging buttress head.
Overhanging buttress head reinforcing bar is intersected with outer wall of basement reinforcing bar and stretches into inside outer wall of basement.
In steel pipe, casting concrete forms steel core concrete column.
Described junction steel plate and peg are arranged in a mutually vertical manner.
Described peg is arranged in a mutually vertical manner with the outermost of overhanging buttress head reinforcing bar.
The outside of described steel pipe is surrounded by the overhanging buttress head pouring, and tangent with the outer wall of basement pouring.
1) steel pipe of junction steel plate, peg and steel core concrete column is welded in advance；
2) after the penstock installation of steel core concrete column puts in place, colligation outer wall of basement reinforcing bar and towards outside outer wall of basement
The overhanging buttress head reinforcing bar that direction is protruded；
3) outer wall of basement reinforcing bar is welded with junction steel plate；Overhanging buttress head reinforcing bar is connected with peg colligation；
4) steel pipe is poured with post inner concrete and forms steel core concrete column；
5) formwork supporting plate, to outer wall of basement reinforcing bar and overhanging buttress head reinforcing bar casting concrete, forms outer wall of basement with outward
Stretch buttress head.
The concrete pouring in step 5) adopts water-proof concrete.
The beneficial effect that the present invention is reached:
(1) concrete and steel interface not with upstream face directly contact, there is the protective layer thickness of abundance, self waterproofing
Can be good；
(2) steel core concrete column not with upstream face directly contact, be conducive to improve steel core concrete column antiseptic property；
(3) outer wall of basement reinforcing bar is connected reliability with steel core concrete column；
(4) overhanging buttress head is equivalent to and wall column juncture area is put more energy into, and is conducive to improving this Regional carrying capacity and steady
Qualitative.
(5) simple structure, construction is convenient.
