Description

Latticed shell structure and its box node holder

Technical field

This Shi Xin Xing Wataru and wide span single layer reticulated shell field of steel structure more particularly to a kind of latticed shell structure and its box section Point holder.

Background technology

Latticed shell structure is a kind of Spacial Frame Structures, has both the property of leverage and shell, and reasonable stress saves material, can To realize larger span, graceful architectural image can be completed.Therefore, the structure is interesting at home and abroad, has wide Development prospect.

Latticed shell structure is usually made of materials such as the steel of high-strength light, aluminium alloys.It can be divided into spherical surface, column by shell form Face, paraboloid, hyperbolic-parabolic etc. (history of large-span space structure -- latticed shell structure and development, accord with it is vertical brave etc.,《Work Cheng Jianshe and design》), with advances in technology and the promotion to esthetic requirement, there has also been more wide for spacial special-shaped curved-surface structure General use.The spacial special-shaped curved surface for building high aesthetic values can be showed, often have asymmetry, cause space several Each beam column, the stress of each node, connection direction are different, the connection type and size of beam column and node Shape also has larger difference.

The common node type of engineering circles includes cast steel node, spherical bolt node, welded spherical node, Xiang Guanjie at present Point, box node etc..Cast steel node is suitable for complex angles, different size connections, but for spacial special-shaped curved surface, each node is equal Difference is not suitable for producing in batches using mold, cost meeting significant increase (engineer application of cast steel node and research, Liu Xiliang etc., Industrial technology).Sphere nodes are also suitable for multi-angle, the connection of more sizes, but are only used for round steel pipe connection, and rod size When larger, node sphere diameter is big, influences architectural image.Tubular joint is usually used in the connection of simple structure, and rigidity is smaller, bearing load Ability is weak compared with other forms, and rod piece quantity is more, angle change in the case of make it is difficult.

Box node is handsome in appearance because its rigidity is big, is applied in many occasions.But box node to multi-angle, The adaptability of more size rod piece connections is more spherical and cast steel node is upper more difficult in design and construction, and node weight is big, increases Structural burden is added.Part researcher uses pipe (single layer box section surface net shell node, the patent No. 2012203824315) Or the method for X-type plate (lattice section contact plate for box section surface net shell, patent No. 201410387484X) a kind of adapts to Multi-angle rod piece connects.Pipe node curved surface connection position rod piece is cut and welding procedure is complicated, and quality control is difficult；X-type plate is most Four rod pieces can only be connected, it is poor for applicability.
