Description
Technical field
The utility model belongs to the building structure technology field, particularly relates to a kind of large-span steel-wooden combination construction moral of showing severity and reins in type individual layer sphere string and prop up the net shell.
Background technology
In recent years, in order to satisfy the requirement of building function of use, large-span space structure is applied to engineering practice more and more, such as public and industrial construction such as terminal, conference and exhibition center, charge station, wide span coal canopies.In numerous form of structure, latticed shell structure is a kind of surface mesh structure, has the characteristics of structural system composed of bar simple structure and thin shell structures reasonable stress concurrently, and it is big to have a span ability, good rigidity, characteristics such as material is economized, and the single and fabrication and installation of member structure are convenient.Latticed shell structure is just used in China in early 1950s to some extent, has built up a large amount of latticed shell structures and has been mostly the each department landmark building at present, like Beijing National grand theater, sports palace, Tianjin, ten thousand people sports palace, Shanghai etc.
A kind of special shape as latticed shell structure; The moral of showing severity is reined in type individual layer sphere string and is propped up the net shell and not only have the tradition moral of showing severity and rein in attractive in appearance, the joint structure characteristic of simple of type individual layer sphere net case structure and shape; Also possess string and prop up the advantage that the distinctive anti-seismic performance of structure is good, save material, therefore be widely used.But at present, this form of structure mainly uses steel as the rod member raw material, does not see the timber moral that is applied to show severity as yet and reins in instance or the research report that type individual layer sphere string props up latticed shell structure.
In China; Timber is a kind of aboundresources, the short recyclable materials of growth cycle; After simple processing, just can become the structural member of good mechanical performance; As the moral that is applied to show severity reins in type individual layer sphere string and props up latticed shell structure, with the application of widening wooden construction and advance the development of Green environmental-protection building.Aspect mechanical property, timber has tension, resistance to compression and bend resistance intensity preferably, is a kind of natural building materials, has just obtained in ancient times to use.But the physiological bending that forms in the timber self-sow process and the stress performance difference of band and perpendicular line have influenced its mechanical property to a certain extent, have limited its scope of application.Along with scientific and technological progress, though existing process equipment can guarantee the profile degree of accuracy of processing back rod spare, receive the restriction of wooden construction connected mode, its range of application fails to be widened always.Aspect the wooden construction connection, common node connected mode is colligation, the tenon fourth of the twelve Earthly Branches, notch, and the node connection reliability is relatively low, nowadays is common in the lower low layer civilian construction of construction landscape and importance.The construction work application facet; Present most of way is it to be pulverized the back process novel building sheet material with other material mixing; Since admixture binder; More or less all can bring pollution to a certain degree to indoor environment, and directly use natural timber actually rare as the case that the large span space string props up the latticed shell structure primary structure member.Therefore, obtain today of well recognized in low-carbon environment-friendly green building theory, the meaning of studying and widen the wooden construction application just seems very great.
And how to improve the reliability of wooden construction connected node, and give full play to the timber mechanics performance, adopt the reasonable computation means to carry out the wooden construction design, also become the key issue that restriction wooden construction application is widened.
Summary of the invention
In order to address the above problem, the purpose of the utility model be to provide a kind of anti-seismic performance good, be convenient to construct, safe and steel-wooden combination construction environmental protection moral of showing severity reins in type individual layer sphere string and props up the net shell.
