The invention discloses a double-layer comb-shaped pattern plate system and an installation method of the double-layer comb-shaped pattern plate system. According to the structure, the double-layer comb-shaped pattern plate system comprises a lower-side pattern plate, an outer-layer comb-shaped pattern plate, an inner-layer comb-shaped pattern plate, a fixed support, a screw, a lug base, a pin, a bottom-layer reinforcing mesh, a top-layer reinforcing mesh, an embedded reinforcing bar, a limiting board, a limiting block, a bottom pattern plate, a panel, a vertical rib plate, a horizontal rib plate, a rib plate, a vertical rod, an inclined rod, a nut and a lug board. The double-layer comb-shaped pattern plate system has the advantages that installation is simple and convenient and after being installed, the double-layer comb-shaped pattern plate system is basically formed and the pattern plates do not need to be adjusted; the integrality is good and a prefabricated concrete board is clear in corner angle and high in accuracy; complementation of the inner-layer comb-shaped pattern plate and the outer-layer comb-shaped pattern plate is achieved, the problems that when the prefabricated concrete board with the horizontal reinforcing bar is constructed, concrete grout leakage of the side face is serious and the pattern plates are quite inconvenient to assemble and disassemble are solved, construction is made to be convenient, and the site is civilized and tidy.
Description
technical field [0001] The invention relates to a double-layer comb-shaped formwork system and an installation method. Specifically, it effectively solves the problems of serious side grout leakage and extremely inconvenient installation and disassembly of formwork during construction of reinforced concrete prefabricated slabs equipped with beards. It belongs to the field of building construction. Background technique [0002] Steel-concrete composite beam structures are being used more and more in the fields of construction and bridges in my country. Among them, the structural form of concrete prefabricated slab + steel box girder is the most widely used because of its simple construction method. The thickness of prefabricated concrete slabs is generally less than 60cm. Some prefabricated concrete slabs adopt a variable cross-section. The main reinforcement of the mesh sheet is extended), and the spacing between the reinforcement bars is relatively dense, and some upper an...
