Description
Technical field
The present invention relates to a kind of space structure of civil engineering more particularly to a kind of assemblings suitable for rectangle plane
Stretching chord arch rib latticed shell structure.
Background technique
Suspen-shell structure is a kind of important space structure system, because of its graceful moulding and succinct reasonable structure type,
It is used widely in large-span space structure.
Suspen-shell structure is made of top single-layer lattice shell, the vertical strut of lower part, radial pull rod or drag-line and circumferential drag-line,
Wherein the upper end of each central shoring bar each link corresponding with single-layer lattice shell is point articulated, and strut lower end is by radial drag-line and single-layer lattice shell
Next link point connection, the strut lower end of same ring are linked together by circumferential drag-line, and total is made to form one completely
System, the Path of Force Transfer of structure are also relatively more clear.Under normal use load action, internal force is passed to by the single-layer lattice shell of upper end
On the strut of lower end, then rope is transmitted to by strut, after Suo Shouli, generates the deboost to support, make total to lower end
The lateral thrust of constraint ring beam greatly reduces.At the same time, due to the effect of strut, each ring of top single-layer lattice shell is substantially reduced
The vertical displacement and deformation of node.
However, in the prior art, it is circular building structure that suspended-dome structure form, which may be only available for plane projection, when
When building projection plane is rectangle, suspended-dome structure is difficult to be applicable in.
Summary of the invention
Can not be applied to plane projection the technical problem to be solved by the present invention is to existing suspended-dome structure is rectangle
Building structure, and site welding workload is big, installation positioning difficulty is high.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of assembling suitable for rectangle plane
Formula Stretching chord arch rib latticed shell structure, including arch rib, drag-line, strut, single-layer lattice shell and reticulated shell bar；The arch rib is using staggeredly string knot
Structure, i.e. arch rib are to intersect parabola shaped, and the parabola shaped diagonal line for being projected as rectangle in the plane of the intersection；It is described
Single-layer lattice shell number is four, and single-layer lattice shell is arranged between the parabola of intersection, and the projection of four single-layer lattice shells in the plane is
Four triangles formed between rectangle diagonal line；The drag-line one end connection strut upper end, the other end connect arch rib or
Another strut；The lower end of the strut connects arch rib, and the upper end of strut connects drag-line；The both ends of the reticulated shell bar connect arch
Rib, centre connection single-layer lattice shell, the side for being projected as rectangle of reticulated shell bar in the plane.
Main stress skeleton of this structure using Stretching chord arch rib as structure, staggeredly Stretching chord arch rib is by curved, string form and arch rib
Bending moment envelope diagram is close, and structural stability is good, steel using amount is few.
Preferably, pin shaft is all made of between the single-layer lattice shell and arch rib, between arch rib and drag-line, between arch rib and strut
Connection.
Further, the arch rib includes a central crossbar segment and 4n extension, n >=1, and is integer；It hands at center
Knuckle section is in X-type, and four ends respectively connect n sequentially connected extensions, between the central crossbar segment and extension, prolong
Flanged joint is all made of between long section and extension.By structural segmented prefabricated, site-assembled design, structure is integrally being constructed
When weld job amount it is less, can be realized efficient green construction.
Further, between the arch rib and drag-line otic placode, the rope head of drag-line are arranged by otic placode connecting node on arch rib
It is connect with otic placode by pin shaft.
The invention has the advantages that the present invention is based on conventional suspended-dome structure principles, to arch by way of the Zhang Xian that interlocks
Rib applies prestressing force, and cylinder single-layer lattice shell is connect with arch rib by pitching ear formula node, forms the prestressing force that plane projection is rectangle
Latticed shell structure, it is suitable for the building structure that plane projection is rectangle, and site welding workload is small, installation positioning difficulty is small.
