Definitions

  • the invention relates to a method for constructing a concrete floor by combination of a deck with concrete casting on site, and to a module mold suitable for carrying out said floor constructing method.
  • Proposals for covering a floor with concrete have heretofore been made by use of a plurality of temporary molds or forms to define spaces to be filled with concrete cast in situ, with removal of the molds after setting or by combination of a plurality of cross molds with concrete cast in situ.
  • the use of temporary molds requires much labor such as assembly, removal, transportation, and storing as well as field materials such as supports and the like which cost much and have not been currently employed.
  • a concrete floor covering using cross molds is made in such a manner that a plurality of as-deposited molds is bridged over longitudinal beams on the lower floor with one series of the molds B' being thinner than the other molds B to provide for zones which are to withstand heavy loads, as shown in Figs. 7 and 8, and that concrete C is then placed--over the molds.
  • This requires edge plugs fitted between the ends B" of the adjacent molds. These plugs are fitted between gaps defined by the adjacent molds and welded to them which involves much labor and cost and elevates the floor to a level D requiring a large quantity of concrete.
  • the floor shown in Fig. 8 is framed by engaging pairs of Z hangers E, E' in the flanges of the respective beams A to receive the molds B between them on which concrete C is placed.
  • the differences in thickness of the concrete layer depend on the lengths of the hangers in pairs.
  • This floor covering provides a floor of small thickness and requires no edge plugs but needs the hangers E to be secured by welding thereby resulting in increased cost and labor. It it therefore desirable to lay a floor with a durable structure but in a simple manner and at a low cost.
  • a surface horizontal or flat surface mold 1 which includes a web 2 and a plurality of reinforcing ribs 5 extending downwards and spaced at a suitable interval W therebetween.
  • Each of the ribs 5 comprises two divergent walls 3 and a base 4.
  • Each of the webs 2 is provided at its opposite ends with a narrow deposit margin 6 and an insert piece 7 at a right angle, respectively.
  • the other opposite ends of the mold 1 are forced (formed, compressed) on the back of the mold to provide widths W" in such a manner that the respective bases 4 lie flat upon the web 2 thus forming abutments 8 at the respective opposite ends.
  • Fig. 3 shows a further embodiment of the present invention, wherein the other opposite ends of the mold 9 are forced (formed, compressed) from the opposite sides thereof (or from above and below) in such a manner that the web 2' and the basis 4' are deformed to form abutments 8' which are positioned between the web surface and the base faces thereby obtaining an elongated hexagon, if viewed from the side.
  • the intermediate portion of the mold 1 or 9 may be formed or pressed flat in such a manner that the ribs form an intermediate abutment 10 to be laid on the beam 11.
  • the abutment 8 or 8' of the mold 1 or 9 fabricated as described above is engaged in and welded to the beam 11, as shown in Fig. 5.
  • a plurality of molds may be arranged in line perpendicular to the axis of the beam.
  • the insert piece 7 of one mold 1 or 9 is mounted in the foremost rib 5 of the other mold 1' or 1" whereas the deposit margin 6 of one mold is placed under the web.
  • the mold 1 or 9 is made of steel, stainless steel, aluminum, fiber reinforced plastics, etc. Although not shown in the drawing, it may be coated with a refractory material and include a basis 4,4' adapted for draining. Further, the web may be ribbed or slightly curved to prevent the web from deflecting due to the weight of the concrete.
  • Fig. 5 shows a combination of two types to the molds such as the flat surface mold 1 and the crown surface mold 9.
  • the concrete may be placed in such a manner that it is rather thick on the flat surface mold to withstand a heavy load and thin on the crown surface mold to withstand a smaller load.
  • the flat surface mold is used for floors where heavy material or equipment is installed.
  • the molds of the combination type are shown in Fig. 5 it is entirely a matter of choice depending on the nature of -1 the building whether the flat surface mold or the crown surface mold is used.
  • the flooring constructed in accordance with the present invention does not require edge plugs nor hangers which are necessary in the prior art methods, but the molds are simply arranged planar along the beams and concrete is placed thereon. No skill is required to execute the work because of the method's simplicity. Furthermore, no accessories are employed so that the trouble and labor of mounting, removal, and adjustment are fully eliminated.
  • the reinforcing ribs 5 are formed on the backs of the molds to render thin steel materials withstandable to greater loads and to obtain a solid and optically pleasing concrete floor.
