Disclosed herewith a prefabricated bathroom and a construction method and an installation method thereof. The prefabricated bathroom includes a bottom unit (11), multiple wall units (12) and a top plate unit (13). One of the wall units (12) is a structural wall (14), which is provided with a recessed top region (141) reserved for later pouring, a middle full-prefabricated structural wall body (142), and a recessed bottom region (143) reserved for later pouring. Top exposed reserve bars (144) of the prefabricated bathroom of a floor are inserted into the recessed bottom region (143) of the prefabricated bathroom of a next floor, and connected with bottom exposed reserve bars (146) thereof, so that the prefabricated bathroom of said floor can be connected with that of said next floor through pouring concrete in the recessed top region (141) and the recessed bottom region (143).

End fittings may be designed so that they connect to each other in more than two configurations. A first end fitting may be connected to an adjoining end fitting, removed, rotated ninety degrees and reconnected with the adjoining end fitting without jeopardizing stability of the position of each end fitting relative to the other. The first end fitting may be connected to the adjoining end fitting, removed, rotated an additional ninety degrees and reconnected with the adjoining end fitting without jeopardizing stability of the position of each end fitting relative to the other. The first end fitting may be connected to an adjoining end fitting, removed, rotated a yet further ninety degrees and reconnected with the adjoining end fitting without jeopardizing stability of the position of each end fitting relative to the other.

A scaffold having an opposing pair of half funicular trusses that are detachably or pivotably connected in the middle to establish a funicular arched truss is provided, where when in a detached or pivoted state, storage and transporting a plurality of the half funicular trusses is simplified.

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.

A formwork part having a compensation element with two transverse supports connected to a longitudinal support. An outer support is movably situated on the transverse supports. A center support may be detachably fastened to the transverse supports. The longitudinal support, the outer support, and/or the center support have/has, preferably at both ends, at least one support head receptacle, in particular formed as a connecting protrusion, in particular at least two support head receptacles, preferably formed as connecting protrusions. The connecting protrusions may be hooked into ceiling supports of the ceiling formwork. The ceiling formwork includes such a formwork part and a formwork element. The formwork element has at least one support head receptacle, in particular formed as a connecting protrusion, which may be hooked into the ceiling support of the ceiling formwork. The ceiling formwork may include the ceiling support, and the ceiling formwork may have a dual support.

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 system for laterally supporting a vertical shoring post is provided. The system includes a head and a jaw assembly, the jaw assembly movably mounted to the head, the head configured for selective engagement with a shoring post, and the jaw assembly configured for engagement with a beam that provides lateral support to the shoring post. The head comprises first and second arms that extend in the same general direction and when engaging the shoring post the first and second arms are disposed upon opposite sides of the shoring post. The jaw assembly includes a fixed jaw and a movable jaw, the moving member pivotably connected to the fixed jaw, wherein the fixed jaw and movable jaws are configured to receive an end of the beam therebetween.

A shoring system for concrete slabs is disclosed. One such system includes a drop head with a beam support member which can be moved between lower and upper positions, and a wedge member which locks the beam support member in its upper position by a translational, sliding movement thereof. Wedge member includes a narrower toe portion and a wider heel portion, and the toe portion is insertable past corresponding engagement surfaces on the post of the drop head, to support the wedge member in its upper position. The beam support member has a lower surface engaged by the wedge member and such lower surface is longitudinally spaced from the upper surface of the beam support member, so that there is open space between the wedge member and the bottom surfaces of beam supported by the upper surface of the beam support member.
