The present disclosure relates to a common tower configured to be erected adjacent a building structure into construction. The tower comprises spaced apart columns, made of vertically aligned column hollow sections, spacedly and substantially vertically positioned adjacent the building structure, and vertically spaced apart flooring structures releasably and slidably supported by the spaced apart columns using a plurality of sliders. Each flooring structure is being capable of vertical displacement when supported by the spaced apart columns. The tower further comprises an anchoring system adapted to securely engage with the building structure to maintain the spaced apart columns substantially upright, as well as protection structures adapted to surround the flooring structures. A safe and easy erection of the tower using a common tower assembly is described.

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).

A utility scaffold is designed to be repeatedly broken down into straighter components to reduce the space requirement for storage and shipment. The scaffold has first and second ladder frames, each comprising a plurality of vertical supports, a plurality of horizontal supports, and a plurality of releasable connections. The horizontal supports are releasably connected to the vertical supports by the releasable connections to form a rigid ladder frame structure. The releasable connections include a male wedge protrusion and a female receiver configured to receive the male wedge protrusion. The female receiver has a passage therethrough, with the passage having a tapered interior surface. The male wedge protrusion and the tapered interior surface are configured to abut when the vertical support and the horizontal support are mounted together via the releasable connection. A fastener is optionally used to secure the releasable connection.
