a. during the construction of a lower layer structure or a raft, inserting a plurality of vertical steel bars at the joint of wall columns close to the wall side;
b. welding short steel bar supports along vertical steel bars from bottom to top, and winding a high-strength dense-mesh steel wire mesh to form an interception net piece;
c. the two sides of the intercepting net piece are tied by using open hoops, the open hoops at the two sides are lapped and welded, and the space between the open hoops is less than or equal to 200mm;
d. when the wall column concrete is poured, the structural column height-labeled concrete is poured firstly, then the two side wall body concretes are poured, when the height of the 1/2 layer is poured, the upper layer concrete is continuously poured after the concrete is settled.
Preferably, before lower floor's roof or basic raft board concrete placement, insert vertical reinforcing bar, the inserted mode is the same with the wall post joint bar.
Preferably, the intercepting net piece is provided with an opening hoop, and the opening hoops on the two sides are welded in an overlapping mode to form an integral concrete intercepting system.
Preferably, when the wall column concrete is poured in the step d, the time for pouring the wall column concrete is 1/2 of the height of the layer, the time is 1-1.5 hours, and after the concrete is settled, the upper layer concrete is continuously poured.
Preferably, the open hoop spacing is 100-200mm.
Preferably, in the step a, 2-3 vertical steel bars with the diameter of more than or equal to 18mm are inserted into the joint of the wall columns close to the wall side during the construction of the understructure or raft.
The invention has the beneficial effects that: the invention adopts the modes of steel bar mesh isolation and butt welding reinforcement of the open hoops to intercept the concrete with different labels on the two sides of the wall column, and adopts a reasonable concrete pouring mode to effectively avoid the problems of incomplete concrete isolation measures on the two sides of the wall column and mutual leakage of the concrete of the wall column, thereby ensuring the engineering quality.
