the annular reinforcing bar of superimposed sheet is used for superimposed sheet interconnect between a plurality of, to some opening (room width) and the big architectural design of depth (room length), transports the work progress of a superimposed sheet alone and hoist comparatively complicatedly, consequently needs the polylith superimposed sheet to combine the back to transport and hoist.
In this embodiment, the splice joints between the superimposed sheets are sealed with construction glue, and the superimposed sheets are provided with triangular reinforcing ribs.
When the size of the floor plate is not satisfied after the plurality of superimposed sheets are combined, the manual supporting template is added.
S2, connection between the laminated slab and wall column, wall or beam slab, the beam slab is used for floor beam, see fig. 2:
the end of the laminated slab, which is far away from the annular steel bar, is provided with an anchor bar, and the anchor bar can extend into the wall column, the wall body and the beam slab;
s3, connecting the beam plate, the wall column and the top plate:
the beam plate is provided with a groove, annular reinforcing steel bars are arranged in the beam plate, the beam reinforcing steel bars are bound in the groove of the beam plate, the annular reinforcing steel bars penetrate through connecting reinforcing steel bars and then are connected with the laminated slab, the bound beam reinforcing steel bars are connected with column reinforcing steel bars on the wall column, and after concrete is poured, the beam plate, the wall column and the laminated slab form a whole;
s4, connecting the wall:
the lower part of the wall body is provided with wall feet, each wall foot is internally provided with a bolt, and when the ground is uneven, the stability and the verticality of the wall body are adjusted through the bolts;
because the cast concrete of the floor slab cannot be guaranteed to be flat in the construction process, the problem that the wall body is easy to incline when the wall body is erected is brought to the construction of the upper-layer vertical wall column, and the wall body is unstable. In the prior art, a cushion block is required to be filled in to enable a wall body to be stable and vertical, but the thickness of the cushion block is possibly inconsistent with the thickness required to be filled in, so that the probability of danger and difficulty in construction is increased. Therefore, the wall corner bolt can ensure that the wall is stable and vertical because the height of the bolt can be freely adjusted.
Annular reinforcing steel bars are arranged at the upper part and two sides of the wall body, and the annular reinforcing steel bars are connected with the wall body above and at two sides after penetrating into the reinforcing steel bars to form a whole; referring to fig. 4, the wall body is provided with supporting through-wall holes which are respectively positioned at the upper side and the lower side of the wall body and are respectively positioned at one third of the height of the wall body, and inclined struts are required to be arranged at the supporting through-wall holes of the wall body for stabilizing the wall body.

It should be noted that the step openings are mainly used for the outer wall bodies or the outer wall columns. The wall body is divided into an outer wall body and an inner wall body, and the wall columns are also divided into outer wall columns and inner wall columns. The outer wall/column is the wall/column around the building and the inner wall/column is the wall/column inside the building.
In addition, the height difference port can also be used for the wall body of the staircase.
