05 CO The invention relates to shipbuilding and can be used in the manufacture of a ship hull. A known method of manufacturing flat ship sections from panels and frame longitudinal-transverse set, which consists in installing frame set 1 on sheets with welded edges. A disadvantage of the known method is the difficulty of mechanizing assembly-welding operations when installing frame sets. The aim of the invention is to increase productivity when installing frame kit. This goal is achieved in that according to the method of manufacturing flat ship sections from panels and frame longitudinal-transverse set, which consists in installing a frame set on sheets with welded edges, the long sides of the frame transverse and the upper side of the longitudinal frame set are flanged from transverse parts and the longitudinal set are made lattice panels, having dimensions multiple to the dimensions of the panels, weld the panels with each other, then install the panels-p on the edges of interconnected panels lattice frame set, wherein the set of transverse ribs attached to the panels via transition parts and the longitudinal frame set its lower edge welded to one of the longitudinal edges of the panel. 01 FIG. Figure 1 shows panels and panels of lattices assembled on flow lines; in fig. 2 - assembled panel; in fig. 3 - installation of the panel-lattice on the panel; in fig. 4 - flat ship section, manufactured by the proposed method. The method is carried out as follows. Panels 1 consisting of sheets 2 and welded longitudinal ribs 3 are assembled and welded, then long edges 4 of transverse set 5 and upper edges 6 of frame longitudinal set 7 are flanged, assembled and welded from parts of transverse set 5 and longitudinal 7, unified panels-grates 8 having dimensions multiple of the sizes of panels 1, then from panels 1 are assembled and welded the cards 9, then the panel-strips 8 are mounted on the edges 3 of the cards 9, then the transitional parts 10 connecting the transverse set 5 and the edge 3 are installed and welded, then The lower edges 11 of the longitudinal set 7 are welded to the ribs 3. The positive effect of using the proposed method is to increase the productivity of labor through the preliminary manufacture of unified panel-gratings on mechanized flow lines. This significantly reduces the amount of manual work during installation and welding of the frame set, reduces the number of welding deformations and the amount of correction work.

METHOD FOR MANUFACTURING FLAT SHIP SECTIONS from panels and frame longitudinal-transverse set, which consists in the fact that on the sheets with welded ribs set the frame set, characterized in that, in order to increase productivity when installing the frame set, the long sides of the frame transverse and the upper side the longitudinal frame set is flanged, lattice panels are made from the details of the transverse and longitudinal set, having dimensions that are multiples of the dimensions of the panels, the panels are welded together, then on the edges Inonii interconnected panels mounted panel-lattice frame set, wherein the set of transverse ribs attached to the panels via transition parts and the longitudinal frame set its lower edge welded to one of the longitudinal edges of the panel. In FIG. 1 shows panels and grating panels assembled on production lines; in FIG. 2 - assembled panel; in FIG. 3 - installation of the lattice panel on the panel; in FIG. 4 - flat ship section, made ³ by the proposed method. The method is as follows. Collect and welded panels 1, sos10 toyaschie of the sheets 2 and 3 welded longitudinal edges, then otflantsovyvayut long transverse edge 4 sets 5 and 6, the upper edges of the longitudinal frame a set 7 collected and welded parts of the transverse and longitudinal set 5 7 ¹⁵ uni fied The panels gratings 8 having dimensions that are multiples of the sizes of panels 1, then they are assembled from panels 1 and cards 9 are welded, then lattice panels 8 are installed on the ribs 3 of cards 9, then ₂₀ are installed and transition pieces 10 are connected, connecting the transverse set 5 and ribs 3 , then m weld the lower edges 11 of the longitudinal set 7 to the ribs 3. The positive effect of the use of the proposed method is to 25 increase labor productivity by prefabricating unified panel gratings on mechanized production lines. At the same time, the amount of manual work during installation and welding of the frame set is significantly reduced, the number of welding deformations and the amount of straightening work are reduced.
