    • PURPOSE:To constitute the above method so that separation of ingredients at the time of conveyance is prevented and filling can be performed while twining round an iron reinforcing rod at the time of compaction of the inside of a concrete shuttering by making use of vibrator, by a method wherein cement, melamine resin, aggregate, a mixing material and water are mixed with one another and agitated by a mixer until high viscosity of such an extent that water on the surface of a matter obtained by batch-granulating a composition having specific slump value is not stuck to a hand. CONSTITUTION:Cement, melamine resin, aggregate, a mixing material and water are mixed with one another and agitated by a mixer until high viscosity of such an extent that water on the surface of a matter obtained by batch-granulating a composition having a slump value of 9+ or -3cm is not stuck to a hand. With this construction, a high-viscosity and high-strength concrete which can obtain compression strength of 300-1,200kg/cm is manufactured and unsolidified concrete is formed into a granular and lumpy state. Furthermore, it may be good that surface-active agent or a retarder, under certain circumstance a thickening agent is mixed into concrete which is formed into the granular and lumpy state or the surface active agent or the retarder, under certain circumstance the thickening agent is stuck to the granular and lumpy concrete.

    • PURPOSE:To reduce the height of the floor of a building and secure the safety of a cable and facilitate wiring by inserting cables on the upper side of the recessed part of a beam for an edge part and permitting the wiring of the cable in the underside space of other beam. CONSTITUTION:On a beam 8a for an edge part laid between the both edges of the girders 7 and 7 which constitute a floor member, a bent plate 15 whose center part is recessed to the lower side is arranged. Other beam 8b is installed so that the upper surface is at the equal height to the girder 7 and the lower edge is at the upper position from the lower edge of the girder 7 and a space part is formed on the underside of the beam 8b. A cable 16 for feeding electricity and transmission is inserted into the recessed part of the beam 8a for the edge part and the underside space for the beam 8b, and wiring is performed. Further, a plurality of trays are formed on the undersurface of a floor panel arranged on the upper surface of the floor member, and a concentrated plug socket, coder/decoder of an electronic calculator, and a wound cable are placed.
