and connecting the box mold superposed top plate with the wall mold and the beam mold.
9. The method as claimed in claim 8, wherein the beam form is fixed to the wall or the structural column by welding or bolting the pre-embedded steel plate below the beam form to the pre-embedded steel plate above the wall or the structural column.
10. The method for manufacturing the concrete box mold according to claim 8, wherein the superposed top plate is fixedly connected with the embedded steel plates above the wall mold and the beam mold through welding or studs.
11. A form-dismantling-free construction method of a concrete box form according to any one of claims 1 to 7, comprising the steps of:
vertically reinforcing and supporting the superposed top plate with a large span and the beam mold by using a detachable steel frame for the prefabricated box mold;
assembling the prefabricated box molds to a specified area layer by layer according to a building structure layout;
laying shear wall reinforcing steel bars between wall forms of horizontally adjacent concrete box forms, laying beam reinforcing steel bars between beam forms, and laying post-cast plate reinforcing steel bars above a superposed top plate;
pouring a shear wall between wall molds of horizontally adjacent concrete box molds;
pouring a bearing beam between beam molds of horizontally adjacent concrete box molds;
and (5) pouring a post-pouring plate.
12. The demolition-free building method according to claim 11, wherein the adjacent wall forms are fixed by a pulling member or a supporting member when the shear wall is cast.
13. The form-stripping-free construction method of claim 11, wherein the post-cast slabs are effectively connected with the laminated top slab into a whole through the truss ribs above the laminated top slab to form a normally used floor slab.
