DEFINITION

Classification: 264/31

(under the class definition) Processes directed to the formation in situ of an erected structure or a part thereof.

(1) Note. Included here are only processes for forming those structures which are not intended to be moved or transported after the final molding step. For example, forming a prefabricated wall is not included here but placed in appropriate subclasses below, while forming a wall or portion thereof in its final intended position is included here. Forming parts by a molding operation and uniting in situ by a second molding operation is also included here.

52, Static Structures (e.g., Buildings),

745.01+, for particular processes of forming or assembling an in situ structure. The line between Class 264 and Class 52 is: Class 52 takes (1) forming in situ erected building structures by uniting preformed modules, e.g., bricks, cinder blocks, etc., and (2) other processes involving molding when combined with a building formation step which is more than a mere perfecting step for the molding such as (a) forming elements by molding, and joining the molded elements together, or to another element, by nonmolding means and (b) uniting a mold form with the surface of the molded body and permitting the form to remain as a portion of the building construction. Class 264 takes process of molding, per se, including forming building structures in situ when such processes include only molding steps. For example, processes for embedding elements such as reinforcements in the molded product or molding structural elements and then uniting the elements by a molding operation are within the scope of this class. 249, Static Molds,

1+, for in situ construction engineering type molds.

404, Road Structure, Process, or Apparatus,

72+, for processes of building roads. The line between Classes 264 and 404, is as follows: Class 404, provides for processes of forming roads except that Class 264 provides for such road making processes which include only the steps of molding monolithic uniform composition structure and/or compacting, treating, stressing or surface working the

material to perfect the molding or curing of the molded body.

405, Hydraulic and Earth Engineering, appropriate subclasses for processes of earthworking, e.g., digging, filling, etc., combined with molding, especially

222, for a method of casting a structure in a marine environment; and subclasses 233+ for a method of casting a pile or pier in situ.
