Abstract
Fish-bellied type cable truss pneumatic die cushion support construction, belongs to technical field of buildings.It mainly protects by the steadying line that winds up, middle part pneumatic die cushion, lower edge track cable and laterally Suo Zucheng.Compared with traditional fish-bellied type cable truss, the advantages of structure, is supporting role of the pneumatic die cushion structure for cable body.Compared with strut, pneumatic die cushion has more superior bearing capacity.What is more important, for the structure that span is larger, it is often necessary to which more struts support cable body, and out-of-plane stabilization cannot be guaranteed, and replace strut to solve the problem of the more constructional difficulties of strut first with pneumatic die cushion, out-of-plane to stably obtain guarantee.There is fish-bellied type cable truss pneumatic die cushion support construction good space-load performance, new in structure to have significant superiority in terms of anti-unstability anti-collapse.It is reasonable in design, convenient for making design and installation, there is very strong practical significance.
Description
Technical field
The invention patent relates to fish-bellied type cable truss fields, and in particular to a kind of fish-bellied type cable truss pneumatic die cushion support construction,
Belong to technical field of buildings.
Background technology
As Urbanization in China is constantly accelerated, people are to such as large-scale exhibition center of public environmental art, stadiums
Deng demand it is growing day by day.This phenomenon has also promoted constantly bringing forth new ideas for large-span space structure form.It is not only in safety, warp
Innovation in terms of Ji, it is often more important that the innovation in terms of moulding meets the aesthetic requirement of people's continuous renewal.In recent years, greatly
Using more in the construction of stadium and gymnasium of span suspended-dome structure, cable dome structure and Cable Truss Structure at home and abroad, it is derived from
Cable Structure takes full advantage of the stress performance of high intensity drag-line, while ensure that structural strength, saves steel using amount, and shape
It is slim and graceful graceful.
Cable Truss Structure is a kind of form of Cable Structure, because it crosses over the factors such as spacial ability is strong, and steel using amount is low, in sport
It is used widely in the public buildings such as venue.Traditional fish-bellied type Cable Truss Structure is often using strut as support system, strut two
End applies prestressing force to strut by prestressed cable, forms independent internal force system.With the Cable Truss Structure of strut support
Shortcoming is mainly in the following aspects：
1, the quantity of strut is more
2, strut is in pressured state, at this time due to the presence of bar stable problem, the section of component cannot design it is too small,
Cause the utilization rate of the strength of materials relatively low, the consumption of steel is also more.
3, when span is larger, the stabilization outside structure own layer is difficult to be guaranteed.
4, when strut occurs to destroy fracture, the rigidity of structure declines obviously, and the safety of total cannot be guaranteed.
Invention content
The purpose of patent of the present invention is to improve the above deficiency, provide a kind of to inflate the cable truss knot that pneumatic die cushion is made to support
Structure.
This fish-bellied type cable truss pneumatic die cushion support construction is by the steadying line that winds up (2), intermediate pneumatic die cushion (1), lower edge track cable (3)
It is formed with lateral protection rope (4)；This novel structure replaces strut using pneumatic die cushion, has saved steel, while by work progress
Become brief.More importantly replace strut that need not consider further that out-of-plane stable problem, overall structure become more with pneumatic die cushion
Securely and reliably, while pneumatic die cushion has good working performance, facilitates the later stage works such as construction, maintenance.
The purpose of the invention is achieved through the following technical solutions：
Fish-bellied type cable truss pneumatic die cushion support construction is by the steadying line that winds up (2), intermediate pneumatic die cushion (1), lower edge track cable (3) and side
It is formed to protection rope (4)；
Intermediate pneumatic die cushion (1) is olive shape structure, that is, both ends point, middle circle；Lateral protection rope (4) at least two, winds up steady
Standing wire (2) is located at the upper end face of intermediate pneumatic die cushion (1), and lower edge track cable (3) is located at the rear surface of intermediate pneumatic die cushion (1), intermediate
Pneumatic die cushion (1) is located at the steadying line (2) that winds up, lower edge track cable (3), the centre for laterally protecting rope (4), laterally rope (4) is protected to be located at
The both side surface of intermediate pneumatic die cushion (1)；Wind up steadying line (2), lower edge track cable (3), laterally protection rope (4) length direction along in
Between pneumatic die cushion (1) axial direction, the steadying line that winds up (2), lower edge track cable (3), laterally protection rope (4) by intermediate pneumatic die cushion (1) block
In the space that length direction is surrounded；
The intermediate pneumatic die cushion and the steadying line that winds up (2), laterally passes through band between protection rope (4) at lower edge track cable (3)
There is the noose (5) of bolt hole to be fixedly connected with high-strength bolt, the outer surface of noose (5) and the surface of intermediate pneumatic die cushion (1) are solid
Fixed connection, then the steadying line that winds up (2), lower edge track cable (3) or laterally the cable body of protection rope (4) passes through noose (5) cavity are adopted
With high-strength bolt (7) by noose (5) fixed closed；
The steadying line that winds up (2) and lower edge track cable (3) and laterally one end of protection rope (4) are welded in place end
On the end plate in portion, the steadying line that winds up (2) and lower edge track cable (3) and where laterally the other end of protection rope (4) is welded in
On another end plate (6) of other end end.
The symmetrical steadying line that winds up (2) and lower edge track cable (3) on the circumferential same diameter both ends of intermediate pneumatic die cushion (1)
One end fix on same end plate, the other end is fixed on the in addition same end plate；Both ends end plate it is parallel and with the steadying line that winds up
(2) parallel with the same plane where lower edge track cable (3)；Steadying line (2) and lower edge track cable (3) wind up in the same end plate
On endpoint have spacing；
One end of two symmetrical lateral protection ropes (4) is solid on the circumferential same diameter both ends of intermediate pneumatic die cushion (1)
On the fixed same end plate, the other end is fixed on the in addition same end plate；Both ends end plate it is parallel and with symmetrical two it is lateral
Same plane where protecting rope (4) is parallel；Endpoint tool of the lateral protection rope (4) of symmetrical two on the same end plate
There is spacing.
Different end plates intermediate coaxial in such a way that star is welded welds together.
Fish-bellied type cable truss pneumatic die cushion support construction of the present invention has good space-load performance, and pneumatic die cushion is for upper
The supporting role of last quarter rope prevents out-of-plane stable aspect to be better than strut.This structure is reasonable, and construction process is simple
Convenient, convenient for making and installing, structural elements is less, and anti-ability of collapsing is strong, has stronger practical significance.With traditional fish-bellied type rope
The advantages of truss is compared, the structure is supporting role of the pneumatic die cushion structure for cable body.Compared with strut, pneumatic die cushion has more
Superior bearing capacity.What is more important, for the structure that span is larger, it is often necessary to more struts support cable body, and
And out-of-plane stabilization cannot be guaranteed, and replace strut to solve the problem of the more constructional difficulties of strut first with pneumatic die cushion, plane
Outer stably obtains guarantee.Fish-bellied type cable truss pneumatic die cushion support construction have good space-load performance, new in structure,
Anti-collapse, there is significant superiority in terms of anti-unstability.It is reasonable in design, convenient for making design and installation, have very strong
Practical significance.
