Description
Technical field
The invention belongs to technical field of structural engineering, and in particular to a kind of seif-citing rate rope bar and rigid mesh shell combined structure and
Its construction method.
Background technique
Seif-citing rate cable-rod structure is a kind of efficient prestressed cable bar self-balance structure system, by the way that compression member to be placed in
, it can be achieved that the efficient utilization of special aesthetic feeling and material in the ocean of drag-line.Therefore, this thought is at the beginning of generation just in sculpture
Field is attempted, and is then occurred again such as tensioning entirety mast and tensegrity tower these representative seif-citing rate ropes
Rod structure.In fact, due to seif-citing rate cable-rod structure it is intrinsic the characteristics of meeting the natural law, material is farthest utilized
With the characteristic in section, the building construction of super-span can be built with material few as far as possible.However proper includes
The seif-citing rate cable-rod structure of tension cable and compression rod fails to be applied in house architectural structure always.Firstly, since its nothing
It is no rigidity under stress state, the rigidity of structure fully relies on the offer of seif-citing rate power, it is then necessary if desired to obtain preferable rigidity
Biggish seif-citing rate is applied to component, compression member will bear very big pressure, cause drag-line and compression member section excessive, together
When huge pretension also will bring very big difficulty to construction；Secondly, seif-citing rate cable-rod structure is influenced by external disturbance,
Response under power excitation is more apparent, and influence time is long, and the damping by material is difficult to eliminate vibration influence in the short period；Most
Afterwards, seif-citing rate cable-rod structure is flexible structure, and the connection with rigid roofing is difficult, and construction is complicated.
And although latticed shell structure is rigid structure, and in-plane stiffness is larger, and rod piece is less, and it is handsome in appearance, it is widely used in
Large-span space structure, but structure Out-of Plane Stiffness is smaller, it is more sensitive to initial imperfection, it is sent out using with easy in work progress
Raw entirety or local buckling.
Summary of the invention
To solve the above problems, the structure will the invention discloses a kind of seif-citing rate rope bar and rigid mesh shell combined structure
Seif-citing rate cable-rod structure flexible connect with the rigid latticed shell structure of rigidity by short column integral, and it is preferably hard and soft to form rigidity
Property composite structure.Not only the characteristics of having remained seif-citing rate cable-rod structure, but also rigid mesh trellis rigid mesh shell is introduced, there is structure
The advantages that spatial extent is big, rigidity is big, structural stability and progressive collapse-resisting ability are strong, easy for construction, while in the net of rigidity
It is easier to be laid with rigid roofing on shell structure.
In order to achieve the above objectives, technical scheme is as follows:
A kind of seif-citing rate rope bar and rigid mesh shell combined structure, described includes seif-citing rate cable-rod structure, rigid reticulated shell and short column.
The seif-citing rate cable-rod structure connect to form assembly with rigid reticulated shell by short column between the two.
The seif-citing rate cable-rod structure can be located at the lower section of rigid reticulated shell, may be alternatively located at the top of rigid reticulated shell.
Seif-citing rate cable-rod structure is the seif-citing rate cable-rod structure system being made of the drag-line and the compression bar being pressurized of only tension,
Its rigidity is totally dependent on the size of seif-citing rate.
The rigidity reticulated shell is the single-layer or multi-layer network that node has just connect.
The short column is located between seif-citing rate cable-rod structure and rigid latticed shell structure, plays connection function, is respectively welded at certainly
On stress cable-rod structure node corresponding with rigid latticed shell structure.
Ratio between the rigidity and seif-citing rate cable-rod structure of composite structure and the rigidity and the two rigidity of rigid reticulated shell
It is related.
Composite structure configuration can be the shapes such as plate, cylinder, spherical surface or free form surface.Seif-citing rate rope bar configuration is according to rigidity
The shape of reticulated shell and change, can be by the configuration of looking for shape to obtain meeting rigid reticulated shell shape, to combine to be formed with rigid reticulated shell
Overall structure.
The construction method of seif-citing rate rope bar and rigid mesh shell combined structure is that will first not apply prestressed flexible cable bar knot
Structure carries out whole promotion, applies after forming the stable seif-citing rate balanced structure with certain rigidity after prestressing force, using answering certainly
Power cable-rod structure carries out aerial dissipate to rigid reticulated shell and spells installation as bracket.
This programme has the following beneficial effects:
(1) seif-citing rate rope bar of the invention combines seif-citing rate cable-rod structure one with rigid reticulated shell with rigid mesh shell combined structure
It rises, the characteristics of both combining, the advantages of not only having remained light-duty seif-citing rate cable-rod structure, efficient, self-balancing, but also steel mesh can be played
Shell makes structure have the advantages that spatial extent is big, rigidity is big, structural stability is good convenient for the advantage of laying rigid roofing plate；From
Stress cable-rod structure can be used as the resilient support of rigid reticulated shell, overcome imperfection sensitivity existing for single-layer lattice shell high, in construction
The problems such as being easy to happen entirety or local buckling.
(2) seif-citing rate cable-rod structure can be assembled by seif-citing rate cable-truss, realizes prefabricated construction.In factory process
Seif-citing rate cable-truss post-stretching forming is made, pretension is established in the cells, becomes self balanced element.Meanwhile seif-citing rate rope
Bar unit lighter weight is readily transported and stores, and self balanced element is transported to live quickly assembling forming, it is convenient to construct, and ties
There is greater stiffness and span after constituting shape；
(3) if the part drag-line in seif-citing rate cable-rod structure fails, where seif-citing rate cable-truss will fail, but can't
Lead to integrally-built continuous collapse, therefore there is stronger progressive collapse-resisting ability.
