A core i4 is disposed above the reenforcement. This core does not extend within the channels 5, S but, on the contrary, lies within the structure with its edges without the margins of the channels so that there is a material amount of cementitious composition I6 surrounding the core and between the core and channels and extending within the channels.- The core, as illustrated, is substantially rectangular and of material thickness may or may not be in contact With the rconiorc'emcnt l i, i2, depending upon the amount of ccmentitious material which iindsitsway therebetween. It is preferably formed of fibrous material, such as paper or wood pulp or the like, but any material which is lighter in weight than the masonry, cement mortar, concrete or other cementltious material that surrounds it on all sides, is suitable.
At spaced points throughout its length and breadth, the coreis perforated, as shown, with transversely extending perforations I8, that is, perfo-rations, which, when the slab is in position, extend in a direction perpendicular to the longer faces of the slab. In manufacture, the channels are placed in position, the reenforcing sheet placed therebetween with the edges extending therein and, if desired, raised above the lower flanges of the channels. A cem-entitious composition is then poured about the core and reenforcement and within the channels, as will be understood. Any cementitious composition having the desired characteristics, which can be poured in substantially fluid state and which will harden or set upon standing, may be utilized. The composition flows all about the rcenforcement and about the core and ows through the perforations I8 therein and exten-ds within thechannels 5, 6, so that the core and recniorcement are wholly embedded therein and bonded thereto. In addition, the composition i'iows through the perforations i8 in the core and completely lilla them and when the composition hardcns, the material in the perforations serves additionally as a bond between the material above and below the core i4. The cementitious material in the passages IS assists in transferring the stresses from the compressive to the tensile side of the construction, as will be understood.
While any cementitous composition may be used it is preferred to use a cement having great capaciiy for adhesion to the core and reenforcing means. As an example, a plastic magnesia. cement of the following formula has given satisfaction.
Parts by volume Calcined magnesia 4 Sand Talcum powder 1 Silex 21/2 -To the foregoing is added a solution which shall preferably have the capacity to overcome or neutralize inherent defects in the magnesium oxide of the mixture. Such a solution has taken the following form: Five parts by volume of a magnesium chloride solution of 22 Baume and one part by volume of magnesium sulphate of 30 4 Baume.
The talcum powder, of course, is added to lend a. waterproofing characteristic to the cement.
The solution and graded aggregate are mixed to the proper consistency and the cement is ready for use.
.il beam or slab construction manufactured in the marmer described has a strength substantially equal to that of the equivalent reenforced concrete construction without the core, but weighs considerably less. Steel is thus saved, in the construction, because of the reduced load. A slab has been tested which is about 51 square and 1%" thiclnand which has an effective span of 49". This slab was reenforced with electrically welded galvanized gauge w'ire forming two inch square meshes, while the carrying channels taking the transverse reactions were bent from a three inch by one-eighth inch steel flat. The core was forty-eight inches square and threequarters inches thick.
A-total load of 421 pounds per square foot has been applied to this slab without ultimate failure thereof. This represents, in the given slab, a total load 016738 pounds. With a total load of 3819 poimds, the maximum deflection at the center of the slab was .483 inches. In the safe work ing live load range, the deflections were as follows:
It will thus be seen that building construction is provided by this invention which is consider,- ably lighter in Weight than that heretofore known although substantially the same strength is afforded, the lightness in Weight being derived by virtue of the displacement of some of the material by material of a lighter weight, which lighter material adds nothing to the strength but which is so constructed as to permit the strength affording material to give to the construction the necessary strength.
A thin floor finish or ooring of an asphaltum mixture, for instance, even as thin as ths of an inch, can be overlaid directlyon slabs of this invention without cracking in use because of the adjacent channels of proximate slabs which support the load and distribute shear. This is because of the two-way reenforcement in the slab by which transverse reactions are taken up by the steel channels at the edges and which run in the direction of the span. It will be seen that because of the superior resistance to moving loads, that its reenforced edges Will reduce the relative deiiection at the joint to an appreciable extent which is of value in reducing the thickness of the flooring to be placed thereon, as it tends 'to inhibit cracking in floor finishes at the joints between the slabs.
