A building component system including a rigid plastic form having an arched shape in each of two perpendicular vertical planes and having a plurality of protrusions configured to engage concrete poured on top of the rigid plastic form. The system also includes concrete poured on top of the form and cured to bind to the form at least at the plurality of protrusions, thereby forming an arched ceiling for a first story of a building and a flat roof or flat floor for a second story of a building.

The invention relates to a unit that comprises a closing piece arranged on a horizontal surface onto which side panels are secured, for which purpose the closing piece has side perforations arranged longitudinally and in line with projections that the side panels have on their lower edge. The side panels are vertically secured onto the closing piece via clips or the like secured onto the closing pieces. Thanks to the structural features of the parts and their engaging design, an assembly is obtained which is easy to assemble and dismantle, allowing girders to be built directly on site, as well as allowing the removal of forms from girders with complex geometries (holes, section reductions, etc.).

A universally adaptable waffle-cavity form and methods for constructing a waffle panel are described. The waffle-cavity form is provided with a standard shape and size and can be easily adapted to alter the dimensions thereof. The form can be cut down and combined with one or more other cut coven forms to provide a combined form with desired dimensions. The forms can also be combined without first being cut down through the use of a saddle that is placed over a joint therebetween. A plurality of the forms can be affixed to a mold decking in a desired arrangement using anchors installed therebetween to form a mold that is reusable to produce multiple waffle panels.

A modular self-supporting arched ceiling structure has a plurality of interconnected modules each extending in a first direction over an arc and arranged one after the other in a second direction which is transverse to the first direction, with each of the modules being composed of a plurality of interconnected panels located adjacent to one another in a direction of elongation of each of the modules, and each of the panels has two plates spaced from each other to form therebetween a space which is filled with a cellular material with one of the plates composed of a plurality of strips of a heavy-duty high-modulus material.

The present invention corresponds to a formwork mechanism for casting and molding concrete, comprising a coffer having a sheet and four plates arranged around the sheet perimeter. Each plate has holes arranged on its front face. Also, the formwork mechanism includes a structural element, connected to one of the plates by fixing means. On the other hand, the structural element has lateral perforations that are aligned with the holes of one of the coffer plates. Fixing means pass through the holes and side holes. The structural element may be a beam, a three or four-beam T, and combinations thereof. On the other hand, using several coffers interconnected with structural elements, formworks are constructed for casting flat reticular slabs; and also for curved reticular slabs with greater slab thickness near the beams supporting the slabs in comparison to the span of the slabs.

A method of manufacturing a waffle slab includes providing a bottom mold separately on columns and exposing joint heads of the columns from the bottom mold; providing first sets of beam bars separately on the bottom mold to be parallel along a first direction; and providing second sets of beam bars separately on the bottom mold to be parallel along a second direction, wherein the second sets b of beam bars are configured to intersect with the first sets of beam bars without interference and together they form accommodation spaces for waffle molds.

A set of extruded profiles for the construction of slabs, beams and columns, which are assembled in a systematic manner and have the function of covering the slab, column and beam, eliminating the need for any finishing, and has the function of serving as to receive the concrete during construction. The constructive arrangement of the parts forming said set of profiles and allowing their assembly in a systematic manner, guarantees numerous functional advantages, as well as in their use and is comprised of five extrusion profiles, preferably PVC, not limited to this material, comprising a main plate, a filling profile, which will replace the Styrofoam block, and three profile variations for column construction.
