DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to an architechtural structure, more particularly, to a curved-surface net-like arched framework formed by inserting and hooking engagements.
BACKGROUND OF THE INVENTION
For constructing large-spanned and widely-covered buildings such as stadiums and gymnasiums, spatial lattice-framed structures have mostly been used, within existing techniques which require at least one of the following: more complicated design and construction; higher accuracy of manufacture for structural members; more consumption of raw materials; longer project time limit; higher cost of construction; and the necessity of employing scaffolds and large-scale sling equipment while under construction. In addition, the buildings made by those techniques can only be positioned permanently at one place, cannot be disassembled and then moved as desired. Furthermore, such techniques have narrow range of application, such as for houses and buildings.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an arched framework widely applicable to various architectureal fields and capable of rapid assembling and disassembling. The assembling and disassembling can be achieved by insertion and extraction, hooking and unhooking of structural members. For the members which form the framework, there will be less varieties, unified standards, simple configurations and easy technologies, and they can be produced mechanizedly and repeatedly in large-scale production. The present framework, with a definite engagement fashion, can be used to construct different kinds of both permanent buildings and mountable buildings. There is no need during its construction for scaffolds and large-scale sling equipment.
Another object of the present invention is to provide a method for assembling the arched framework without any high-altitude operation.
The objects of the present invention can be achieved in the way where the structural members include curved bars, straight bars, tie rods, chord members, double curved bar units, rectangular-shaped bullet connectors, cross-like universal bullet connectors, semicircular multi-head bullet connectors and cross-like, T-shaped and right-angled bullet connectors which generally are referred to as bullet connectors. By utilizing straight bars; tie rods or chord member as commonly-used members; providing curved bars or double curved bar units; selecting corresponding bullet connections; and by means of inserting and hooking engagements, an arched framework of curved-surface net-like single-tier type, double-tier type and single- and double-tier hybrid type, as well as spheric net-like single-tier type can be made. Either a single-tier type or double-tier type or single-and double-tier hybrid type arched framework can be the main body of a building, and a spheric single-tier type arched framework can be the end closure for main body structure. There is also an elevational gable wall type of end closures. The main body and end closures are connected to each other by attachments.
Each structural member of a single-tier arched framework includes a plurality of curved bars, straight bars, tie rods and chord members and cross-like, T-shaped and right-angled bullet connecters which generally are referred to as bullet connectors. In the framework each, bullet connector is insertingly engaged with straight bars and curved bars, and hookingly engaged with tie rods and chord members. A plurality of curved bars are insertingly engaged along a curve, through a plurality of bullet connectors, to form an arc-shaped frame. A plurality of chord members are used, through the bullet connectors, to connect the arc-shaped frame formed by insertingly engaged curved bars into a unit. A plurality of arc-shaped frames, parallel to each other and having the same projective plane, are longitudinally connected together, through the bullet connectors, by a plurality of straight bars.
All of the straight bars connected along straight lines form trusses. The trusses are parallel to each ot
