A prop head assembly is configured to be fixedly connected to a vertically-extending construction column, and also configured to support a horizontal construction beam assembly once the prop head assembly is fixedly connected to the vertically-extending construction column. The prop head assembly includes a first beam-locating feature and a second beam-locating feature. The first beam-locating feature is configured to selectively receive, at least in part, a beam-reference portion. The second beam-locating feature is also configured to receive the beam-reference portion once the beam-reference portion is inadvertently displaced away from the first beam-locating feature and from the vertically-extending construction column and toward the second beam-locating feature.

An apparatus includes a construction column configured to extend perpendicular relative to a ground surface, a construction beam assembly configured to be positioned perpendicular relative to the construction column, and a prop head assembly configured to be fixedly connected to an upper end portion of the construction column and to support the end portion of the construction beam assembly. The prop head assembly defines first and second recesses configured to selectively receive a pin of the construction beam assembly therein.

Apparatus includes construction component. With reference to embodiments as depicted in FIG. 1 to FIG. 30, construction component includes prop-head assembly. Apparatus may be provided for vertically-extending construction column and horizontal construction beam assembly having beam-reference portion. Apparatus includes prop-head assembly configured to be fixedly connected to vertically-extending construction column, and also configured to support horizontal construction beam assembly once the prop-head assembly is fixedly connected to vertically-extending construction column. Prop-head assembly includes first beam-locating feature and second beam-locating feature. First beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature is also configured to receive beam-reference portion once the beam-reference portion is inadvertently displaced away from first beam-locating feature and from vertically-extending construction column and toward second beam-locating feature.

A coupler comprises a first channel having a first axis of extension in a first horizontal direction and a second channel having a second axis of extension in the first horizontal direction. The second axis of extension is parallel to and spaced apart from the first axis of extension in a second horizontal direction. The second axis of extension has a pitch angle relative to the first axis of extension in a vertical direction, the pitch angle being less than 180 degrees. The first and second channels each include head-mounting features, the head-mounting features constructed and arranged to retain an elongated head to the coupler while permitting movement of the elongated head relative to the coupler in the first horizontal direction.

The various embodiments of the present invention provide a modular slab formwork with easy shuttering and de-shuttering assembly. The formwork comprises a formwork panel and a drophead. The formwork panel comprises a plurality of side connectors, a base frame, and a form-lining. The base frame comprises a corner element on each corner. The drophead is connected to each corner of the formwork panel through the corner element. The corner element forms a locking notch to lock at least two formwork panel with each other as well as with the drophead.

The invention relates to a head for a formwork prop, which comprises a lower pin for connecting to the prop, a base for supporting beams, and four projections arranged to form a rectangle defining a long side and a short side, each projection being disposed at a corner of said rectangle, the rectangle delimiting an area for receiving beams. The head comprises two plates perpendicular to the support base, the plates being arranged parallel to each other and to the long side such that the plates leave a space therebetween for a beam and respective spaces for a beam in the space between the ends of the plates and one of the projections, each plate comprising at least two housings for attaching a beam.

A coupler comprises a first channel having a first axis of extension in a first horizontal direction and a second channel having a second axis of extension in the first horizontal direction. The second axis of extension is parallel to and spaced apart from the first axis of extension in a second horizontal direction. The second axis of extension has a pitch angle relative to the first axis of extension in a vertical direction, the pitch angle being less than 180 degrees. The first and second channels each include head-mounting features, the head-mounting features constructed and arranged to retain an elongated head to the coupler while permitting movement of the elongated head relative to the coupler in the first horizontal direction.

According to one embodiment a horizontal formwork system is provided that includes a pair of parallel longitudinal beams on which a safety means is coupled for protecting against falling. The safety means includes a safety structure that is located below the formwork panels. The safety structure at least partially covers a gap existing immediately after a last assembled formwork panel and displacement means for moving the safety structure in a longitudinal direction along a length of the longitudinal beams. The displacement means is configured to be operated on by an operator allow to move the safety structure to cover the gap immediately after the last assembled formwork panel. A safety method for installing formwork panels is also provide that may include the steps of assembling at least one guide to the corresponding longitudinal beam and coupling a safety structure having at least one guided element to the longitudinal beams through a guide, and sliding the safety structure along the guide to cover the gap.
