Abstract

A building panel, comprising a concrete portion with an inner and outer face, and an enclosing boundary portion around the inner face perimeter, with a rigid planar plastic sheet against the inner face, and spacing studs against the outer face, the studs including fasteners protruding through to embed into the concrete. Also, a method of forming the building panel comprising the steps of forming an enclosed-perimeter outer framework, positioning a plurality of spacing studs which include fasteners extending upwards within the outer framework, placing a planar plastic panel within the frame over the top of the studs with the fastening members protruding through, then pouring concrete into the frame to cover the panel, and fill the framework to the required depth, then removing the outer frame from the cured concrete.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]This invention relates to pre-formed or pre-cast building panels and methods of manufacturing these panels. The invention also relates to building panels that are pre-cast using an improved casting bed.[0003]This invention also relates to an improved apparatus for fastening pre-formed building panels together, and a method of fastening building panels in place using the improved apparatus.[0004]This invention also relates to an improved method of casting other building elements into a pre-formed building panel.[0005]2. Description of the Prior Art[0006]Pre-casting structural elements such as wall or floor panels is a method used to form prefabricated building elements that is well-known in the construction art. Prefabricated wall panels are typically cast either at a location other than the building site or sites where they are to be used, with the sections then delivered to sites as required, or they are cast on-site.

Problems solved by technology

This removes a degree of flexibility from the construction.

The manner in which the mix of elements is added and arranged in the outer mould framework can also tend to work against flexibility and modularity.

While this configuration has the advantage of constructional flexibility, the final product may not be suitable for some applications, for example where structural strength is required between the panel and the studs.

As two pours are required, time and complexity is added to the panel forming method.

Storing and transporting heavy concrete studs adds to the complexity of the building logistics, and usually requires additional storage space.

This arrangement can limit the options that are available for attachment of inner drywall panels (drywall is also commonly known as gypsum board, plasterboard, and GIB™ board, depending on the country).

This arrangement adds complexity and weight to the final construction.

A further difficulty that can arise when casting concrete panels is mitring the lip correctly.

If the mould is formed with what will be the outer face of the panel towards the forming surface or floor, it can be difficult to correctly form these corners, as one wall of the mould will be required to be angled inwards.

As concrete is poured, it can tend to cavitate (cause cavities) against the inner face of the wall of the mould.

This means that this face of the panel, once removed from the mould, will not be smooth or perfectly formed.

Another difficulty that can arise with the forming methods known in the art is rotational lifting of the panels.

An additional difficulty that can be experienced when building structures using prefabricated elements such as building panels is the difficulty of correctly aligning these elements and fastening them together.

If the location of the apertures or the fasteners is not correct, the upper and lower panels will not correctly align.

Rectifying this can be expensive and time-consuming.

A third difficulty with using pre-cast construction elements is that of forming windows and doors into wall panels during the panel forming process.

Apart from this, windows are generally not standard structures.
