Detailed Description
The present invention is thus realized, as further described below with reference to fig. 1-6: an assembled formwork shell plate for building interior walls is composed of two identical concrete formwork shell plates 1 and a plurality of connecting reinforcing steel bars 2; the top surface of the concrete formwork plate 1 is provided with an isosceles trapezoid boss 4, the bottom surface of the concrete formwork plate is provided with an isosceles trapezoid groove 5, and a steel reinforcement framework mesh 3 is arranged in the isosceles trapezoid groove;
the steel bar framework mesh 3 consists of a plurality of transverse thick steel bars 30, a plurality of vertical thick steel bars 31, a plurality of transverse thin steel bars 32 and a plurality of vertical thin steel bars 33;
the two identical concrete formwork plates 1 are parallel to each other and are positioned at two ends of the connecting reinforcing steel bars 2, and the connecting reinforcing steel bars 2 are perpendicular to the concrete formwork plates 1 at the two ends and are welded with the steel reinforcement framework mesh 3 in the concrete formwork plates;
a plurality of transverse thick steel bars 30 in the steel bar framework net piece 3 are equal in length to the concrete formwork plate 1, and are uniformly arranged in parallel and welded with each other; the plurality of transverse thin steel bars 32 and the plurality of vertical thin steel bars 33 are uniformly distributed and are welded with each other, and are positioned at one sides of the transverse thick steel bars 30 and the vertical thick steel bars 31 to be welded with each other to form a rigid framework.
A steel reinforcement framework net piece 3 used for an assembled type formwork shell plate for a building inner wall needs to be subjected to anticorrosion treatment.
The field construction of the invention is realized as follows:
1) cleaning residual concrete on the ground beam and finding a horizontal layer;
2) paying off and arranging plates;
3) binding main body constructional column steel bars 6 and shear wall steel bars 7;
4) hanging a double-line assembled mould shell plate for placing an inner wall;
5) after the assembled formwork shell plates for the inner wall of one layer are installed, the dimensional error needs to be checked to ensure that the size of the formwork shell plate conforms to the dimensional accuracy of the cast-in-place reinforced concrete wall, and then the assembled formwork shell plates for the inner wall of the second layer are assembled until the formwork shell plates are installed to one layer height;
6) checking whether the joint of the assembled mould shell plate is tightly sealed or not to prevent the leakage of cement paste, then pouring the mixed cast-in-place concrete 8 in situ, and vibrating to compact;
7) the next procedure circulation is directly carried out without disassembling the template and plastering treatment of the inner and outer wall surfaces.
The invention has the following beneficial effects:
1) an assembled formwork shell plate for building inner walls forms an extremely stable rigid integral structure, saves the traditional procedure of assembling and disassembling a formwork of a high-rise building, improves the construction efficiency and reduces the construction labor intensity.
