Peripheral Slab Formwork System

A perimetral formwork system, applicable for configuring a formwork overhanging a base grid formwork configured by a series of primary beams between which formwork panels are housed, said primary beams being coupled in support bolsters integral with vertical props supporting the base formwork, the formwork system comprising:

• first perimetral beams incorporated within the formwork system extending from the base formwork, either in a direction that is parallel to a primary beam, or in a direction that is perpendicular to the primary beam, having side supports for supporting perimetral formwork panels;
• the first perimetral beams being provided on the lower part with:
• a moving connector for coupling a prop which can be moved to a chosen position;
• an inclined connector for coupling an inclined prop;
• and
• an end housing for coupling a railing shoe;
• the formwork system further comprising:
• a fixing mechanism for fixing the first perimetral beam to the base formwork,
• a straining piece which is placed vertically between the outer and inner perimetral formwork panels, comprising a structure formed by an upper and lower profile connected by intermediate profiles, the upper profile of which is provided with upper end supports fitting between the perimetral beams, and lower connectors set out from the lower profile, ends of which are provided with stops forming a support area of the first perimetral beams, for their coupling in props, and comprising an intermediate profile having of a central web provided with a linkage hole;
• and
• a formwork stripping tool having support tongues which the outer perimetral formwork panels fit in and a linkage coupling in the linkage hole of the straining piece with regard to one that the formwork stripping tool links to for aiding in lowering the outer perimetral formwork panels.

A perimetral formwork system applicable for configuring a cantilever on a base grid formwork configured by a series of primary beams between which formwork panels are housed, said primary beams preferably being coupled in support bolsters integral with vertical props supporting the base formwork, the formwork system comprising:

• second perimetral beams incorporated within the formwork system extending from the base formwork, either in a direction that is parallel to a primary beam, or in the direction that is perpendicular to the primary beam, having side supports for supporting perimetral formwork panels,
• the second perimetral beams having a same geometry as the primary beams and extending with regard to the base formwork combined with perimetral clamps having an L-shaped configuration, in the base of which guides are located which one of ends of the second perimetral beam fit in, and in its lower side having an inclined connector coupling on an inclined prop, and in its vertical arm having a joining mechanism securing the joint of the second perimetral beam to the perimetral clamp, a housing receiving a railing shoe being provided in said vertical arm;
• and
• a fixing mechanism for fixing the second perimetral beam to the base formwork.
