DESCRIPTION:
BRIEF SUMMARY
BACKGROUND TO THE INVENTION
In the construction industry, cavity walling is generally made from two skins of brickwork and block work with a cavity between. This can be replaced by prefabricated building elements in the form of boards made as cavity panels having adequate mechanical properties.
A major problem is to fix such panels together firmly and accurately and to fix them in place on ground or floor.
THE INVENTION
According to one aspect of the invention, there is provided a building element. It will be appreciated immediately that the element can have much wider application than to walling. For example, the elements can be fixed together for floor or ceiling purposes, or again can be complete cylinders fixed one above another to form a support tower.
In transporting the prefabricated building elements according to the invention, there is a danger of the projecting fixing members being broken off or damaged by mis-handling. Therefore, according to another aspect of the invention, there is provided a building element in kit form. In use, this is assembled into a building element.
In the embodiments to be described in more detail with reference to the drawings, the main member is a panel and is double skinned. While fixing of one panel to another or to an anchorage can be contemplated to occur in the middle of a panel (to form a T-joint) the panel will normally be arranged (once assembled) or adapted (when in kit form) to have the fixing members in the region of an edge thereof. In a building system employing such panels, there will normally be a variety of different panels to be used in different ways within the final structure. In one such panel, the fixing member will project from an edge of the panel and in a direction parallel to the plane thereof. This will facilitate in-line fixing together of the panels when the fixing members project sideways and fixing of the panels to a base when the fixing members project downwards. The fixing members can also project adjacent an edge of the panel and in a transverse (preferably perpendicular) direction to the plane thereof. This facilitates formation of corners in a structure.
A particular sturdy form of the fixing member is as a pin with the shoulder circularly symmetric around the pin. For more positive location and locking of the fixing member to a contiguous co-operating element, the pin has a circularly symmetric neck there-around provided by said shoulder and an opposing shoulder. For anchoring the element, e.g. to a floor, the fixing member is formed as a rod with a bend to provide said shoulder. This bend can be in the plane of the panel or transverse (and preferably perpendicular) to the plane of the panel. The panel will usually have both at least one pin in the region of a side edge of the panel for sideways connection and at least one rod in the region of a bottom edge of the panel for anchorage to a base.
As the element is assembled from the main member and the fixing member as separate items, there will be provided holding means to hold the two together. Such holding means may comprise mutually co-operating threaded means with which the two members are provided or may comprise at least one outwardly facing shoulder on the fixing member, at least one inwardly facing shoulder on the main member and a retaining member arranged or adapted co-operating with such shoulders to prevent withdrawl of the fixing member from the main member.
As the main member is a double skinned panel, it is provided, for the purpose of in-line fixing to another element, with a block between the skins in the region of an edge of the panel, the element being arranged or adapted for the fixing member thereof to extend through the block and be held to the main member by the holding means at the inner face of the block. Preferably, the holding means then comprise internally threaded means on a plate fixed to the said inner face.
For corner fixing, as the main member is a double skinned panel, it may be provided with two spaced apart blocks extending alongside each other
