DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to building structures and the constructing and erection of prefabricated buildings.
In particular this invention relates to prefabricated buildings utilising prefabricated steel framing and especially framing constructed from rectangular hollow section frame members. However other section metal frame members may be utilized such as open channel, I-section and Z-sections and the like, where suitable.
Many construction methods have been proposed to provide a simple and cost effective steel framing system for buildings to take advantage of the characteristics of steel fabrication which facilitates accurate factory prefabrication. The latter feature provides the potential to supply bolt together frames which may be erected on site in a relatively short time by relatively unskilled labour and to provide an open structure supporting a roof beneath which the subsequent building operations such as adding the services and finishes, may be carried out under cover of the supported roof.
While many methods have been proposed and some have been commercialised, factory prefabrication of frames and on site bolt together style erection has not as yet provided sufficient benefit to builders to seriously challenge conventional on site timber construction techniques as the predominant construction method for dwellings.
A further disadvantage with the presently used construction methods is that it is difficult to modify existing stock plans to sit individual requirements and at the same time be able to readily provide an accurate estimation of the cost of construction of a new structure. Ready cost estimation is even more difficult where a design layout is prepared to individual requirements.
SUMMARY OF THE INVENTION
The present invention aims to alleviate at least one of the above disadvantages and to provide improvements in building structures and the constructing and erection of prefabricated buildings which will be reliable and efficient in use.
With the foregoing in view, this invention in one aspect resides broadly in a building structure formed from transportable prefabricated panel frame sections including wall and/or floor and/or roof panel frames, the wall frames being formed from a plurality of similar wall panel frame sections each having frame side members and said wall panel frame sections being arranged with the frame side members of adjacent wall panel frame sections in spaced relationship whereby side panel frame sections may be interconnected to joining members positioned between said frame side members.
The frame side members suitably include upright member which extend between the upper and lower extremities of the panel frame sections providing load paths at the extremities of segments permitting roof, wall and floor loads to be transferred directly to footings or floor support means. However if desired the frame side members may be respective upper and lower fabrications associated with the ends of the panel frame sections and protruding from the ends thereof. The joining members are preferably independent of the frame sections but may be formed integrally with the panel frame sections if desired.
Preferably the transportable prefabricated floor and roof frames are also formed from a plurality of similar panel frame sections each having frame side members arranged in closely spaced relationship whereby they may be interconnected to joining members positioned therebetween and suitably to common joining members which tie the floor walls and roof frames together. It is also preferred that the floor and wall panel frame sections are rectangular frame sections and have common dimensions between frame side members such that the spaces between interconnected floor and wall panel sections may be medially intersected by respective vertical grid planes extending at right angles to the panel frame sections. This arrangement enables building structures to be stably erected segmentally, with segment widths corresponding to the widths of the panel frame sections.
