Pre-fabricated bathroom

Abstract

A method of construction and installation of a self contained bathroom unit which is capable of installation in multi-storey buildings. The bathroom unit may be fabricated at a site remote to the site of installation and can be transported to the site as and when required. The bathroom walls are cast with conduits and spaces for light boxes and openings for windows and drainage. Hooks are also cast into the walls to enable the bathroom unit to be lifted to the desired location. The bathroom units are seated on a foundation which is laid for this purpose. The top slab of the bathroom unit can then be used as the formwork and a topping slab is cast in situ to form the floor of the next floor.

1 . A method of construction of a self contained bathroom unit capable of installation in multi-storey buildings wherein the bathroom unit may be prefabricated at a site remote from the installation site and wherein the bathroom unit consists of a slab unit, four wall units and a roof unit all of which are constructed using reinforcement and concrete of the appropriate strength and wherein the said bathroom unit may be disposed with conduits and with openings and spaces within the wall units in accordance with the design of the building and wherein the slab unit may be disposed with recesses on the bottom surface.  
     
     
         2 . A method of construction of a bathroom unit as claimed in  claim 1  above wherein the base of the bathroom unit is cast by pouring concrete of the appropriate strength over slab reinforcement of the desired size.  
     
     
         3 . A method of construction of a bathroom unit as claimed in  claim 1  above wherein the walls of the unit are formed by fixing reinforcement of the appropriate configuration to the slab unit and wherein hooks and conduits are disposed within the wall reinforcement and wherein the wall reinforcement is disposed with suitable openings and spaces and wherein the reinforcement is surrounded by suitable formwork and wherein concrete of the appropriate strength is poured into the formwork.  
     
     
         4 . A method of construction of a bathroom unit as claimed in  claim 1  wherein the roof slab is cast by fixing formwork in the roof space of the precast bathroom unit and pouring concrete over the formwork.  
     
     
         5 . A method of installation of a prefabricated bathroom unit in a multi-storey building wherein the bathroom unit may be seated on suitable levelled pads disposed at various points on the floor surface where the unit will be installed and wherein a layer of cement sand slurry has been applied to the floor surface.  
     
     
         6 . A method of installation of a prefabricated bathroom unit as claimed in  claim 5  above wherein a layer of suitable compressible material may be attached by suitable means to the inner face of the external structural walls and openings in the structural walls  
     
     
         7 . A method of installation of a prefabricated bathroom unit as claimed in  claim 5  above wherein the joint between the structural wall and the bathroom unit may be sealed by means of a non-shrink grout of other suitable non-shrink material.  
     
     
         8 . A method of installation of a prefabricated bathroom unit as claimed in  claim 5  above wherein the top slab of the bathroom unit may be used to form the formwork for the topping slab which forms the floor of the unit above and which maybe cast in situ.  
     
     
         9 . A method of installation of a prefabricated bathroom unit as claimed in  claim 5  above where in the inner face of the structural walls may be disposed with a recess.
