Description
Technical field
The bamboo net shell hollow ball connected node that the utility model relates to a kind of weldable steel inserted sheet, belongs to latticed shell structure field.
Background technology
Latticed shell structure is take rod member as basis, along certain curved surface, arranges regularly and the space structure system that forms, with " film ", act as main stress characteristic.Latticed shell structure is good from heavy and light, the rigidity of structure, and structure is changeable, and aesthetic property is strong, and can cross over larger space, therefore has wide development space.Latticed shell structure extensively adopts steel and aluminium alloys as main structure body material, there is not yet bamboo wood and be applied to the example of latticed shell structure, also just there is no the example of bamboo net shell connected node.
In China, bamboo wood is a kind of aboundresources, growth cycle short renewable, degradable biological material.Bamboo wood is generally just used for craft articles or as decorating and renovating material, but current process technology can become bamboo processing the structure material of good mechanical performance, if be made into structural member, be applied to latticed shell structure, will widen the application of bamboo structure and advance the development of Green environmental-protection building.
But bamboo wood is different from steel, aluminium can be directly welded to connect through row, be also different from concrete and can merge voluntarily and solidify connection, if use for reference the Tenon of Traditional Wood structure, connect, can weaken bamboo wood link cross section, reduce node strength, easily there is brittle fracture.Therefore the connected mode which kind of adopts be easy to realize couples together bamboo rod member rapidly reliably, becomes the key issue that can bamboo latticed shell structure be realized.
Summary of the invention
The bamboo net shell hollow ball connected node that the utility model proposes a kind of weldable steel inserted sheet, its object is intended to overcome the existing the problems referred to above of prior art, have simple in structure, easily location and installation, power transmission is clear, good integrity, easy-maintaining, the advantages such as environmental protection.
Technical solution of the present utility model: a kind of bamboo net shell hollow ball connected node of weldable steel inserted sheet, its structure comprises M steel inserted sheet, M root bamboo rod member, M or M-1 put more energy into steel disc, hollow ball, a 2M bolt; Reserved circular arc type breach on one end of each steel inserted sheet, reserved A bolt hole on the other end of steel inserted sheet; One end and the hollow ball of the reserved circular arc type breach of steel inserted sheet are welded and fixed; Reserved groove and B bolt hole on the end of each root bamboo rod member, insert in the reserved groove of bamboo rod member one end of steel inserted sheet prepared screw-bolt hole, the reserved A bolt hole of steel inserted sheet aligns with B bolt hole reserved on bamboo rod member, and A bolt hole, B bolt hole are fixed with two bolts; On the steel inserted sheet between bamboo rod member and hollow ball, weld the steel disc of putting more energy into.
Advantage of the present utility model:
1) simple in structure: the center of connected node is a hollow ball, one end of the reserved circular arc type breach of steel inserted sheet is welded on hollow ball, insert in the reserved groove of bamboo Rod end one end of the reserved A bolt hole of steel inserted sheet, then A bolt hole reserved steel inserted sheet is alignd with B bolt hole reserved on bamboo rod member, A bolt hole, B bolt hole are fixed with bolt; The last steel disc of putting more energy into that welds on the steel inserted sheet between bamboo rod member and hollow ball, can form a bamboo net shell hollow ball connected node.
2) easy location and installation: the center of connected node is a hollow ball, and the radius of the reserved circular arc type breach in steel inserted sheet one end is consistent with connected hollow ball radius, therefore the angle that no matter steel inserted sheet is welded on hollow ball is how many, can guarantee to be connected with the tight of hollow ball, and location is convenient; Insert in the reserved groove of bamboo Rod end one end of the reserved A bolt hole of steel inserted sheet, and reserved B bolt hole on the align reserved A bolt hole of steel inserted sheet and bamboo rod member, with fixing connection and the installation that can complete bamboo rod member of bolt.
3) power transmission is clear: the suffered internal force of bamboo rod member passes to steel inserted sheet by bolt, and steel inserted sheet passes to hollow ball by weld seam by power, and Path of Force Transfer is clear and definite.
4) good integrity: the steel inserted sheet being welded on hollow ball is equivalent to a cantilever construction, for fear of bamboo rod member at Nodes because cross section is excessive and staggered, steel inserted sheet need be given prominence to bamboo rod member one segment distance, make like this cantilever span of single steel inserted sheet increase, the outer bending rigidity of plane diminishes, in the outstanding bamboo rod member part of steel inserted sheet, weld the steel disc of putting more energy into, the steel inserted sheet of all directions is connected in turn, both reduced the cantilever span of single steel disc, increase the out-of-plane bending rigidity of single steel disc, make to be again connected to steel inserted sheet on same hollow ball jointly stressed, thereby improve the resistance to overturning of node.
5) easy-maintaining: when bamboo net shell is in installation or use procedure, when bamboo rod member is badly in need of changing because there are safety and stablization that the situations such as crack, overbending affect whole latticed shell structure, only need unload bamboo rod member two ends for being connected bolt used with steel inserted sheet, take off the bamboo rod member of damage, change new bamboo rod member, the bolt unloading before tightening again, can complete maintenance work.
6) environmental protection: China's bamboo timber resource is abundant, selection facility; Bamboo wood growth cycle is short, and belongs to the renewable resource of environmental protection, therefore outstanding as the environment-friendly advantage of the bamboo structure Reticulated Domes of main structure body material with bamboo wood.
