Description
Technical field
The utility model relates to a kind of string branch purlin structures applied in rigid roofing cable dome structure
Background technique
Cable dome structure is a kind of based on tension integral structure concept, is made of the strut of drag-line flexible and rigidity complete
Tension structure, structure can make full use of drag-line tensile strength, so as to realize large span with least steel using amount.
The initial purpose of invention dome structure is the disadvantage for overcoming air-supported membrane structure reliability lower, therefore the Suo Qiong of getting up early
The roofing of roof construction mainly uses membrane material.Membrane material is beautiful simultaneously also with some strength from heavy and light, architectural effect.However film
Material has certain translucency, and thermal insulation property is also poor, often wants when holding the activity such as competitive sports or theatrical performances in venue
Ask roof system opaque.Since membrane material sound-proofing is poor, sound equipment and cheer in venue etc. also can form noise pollution outside venue.Institute
Gradually have with the cable dome structure built in the recent period some using rigid roofings materials such as glass, profiled sheet and almag plates
Material.
Rigid roofing material needs purlin structure support.Purlin generallys use square steel tube, C-type steel and Z-type in building structure
Steel lightweight steel component forms primary and secondary purlins bearing roof boarding etc..In building structure especially space structure roof system it is usual
Main purlin is set up between node, then is set up time purlin between main purlin and formed roofing supporting system.The node of cable dome structure
Spacing is big compared with general building structure, increases the span of winner's purlin, meanwhile, the structured grid of Cable dome compares general building structure
Roof system is more sparse, and the especially main purlin of every purlin needs to undertake the weight of greater area of roof system.Using common buildings knot
Purlin is possible to be unsatisfactory for the requirement of bearing capacity in structure or purlin section is excessive, and architectural effect is bad, and excessive self weight is also given
Thematic structure increases burden.Therefore, it is necessary to develop new roof purline structures.
Utility model content
The utility model in order to solve rigid roofing Cable dome because euclidean distance between node pair greatly and undertake load weight, to Design of Purline
More highly difficult problem is brought with construction, prestressed purlin can be applied to purlin using the rigidity of drag-line component by providing one kind
Structure.The utility model can reduce purlin span, improve purlin bearing capacity, meanwhile, also can be improved roofing supporting system with
The co-operation performance of main body cable dome structure.The technical solution of the utility model is as follows:
A kind of string branch purlin applied in rigid roofing cable dome structure, including purlin 1, for connect purlin 1 and just
Property roofing Cable dome drag-line 3 strut on node 4, rest 5 is fixed on node 4 on strut, two rests 5 support a purlins
Item 1, the string branch purlin further include at least one adjustable support rod 2, and one end of adjustable support rod 2 is fixedly connected with purlin 1,
The other end is fixedly connected with drag-line 3, and the length of adjustable support rod 2 can be adjusted.
Preferably, elongate or shorten adjustable support rod by the way of turnbarrel.Adjustable support rod 2 divides be to pass through
Sleeve 8 is connected, and the end of two sections and sleeve inner are provided with contrary mutually matched screw thread 9.
Preferably, the connection type of purlin 1 and drag-line 3 are as follows: 2 upper end of adjustable support rod is connected by pin shaft with purlin 1；It can
It adjusts 2 lower end of strut to be connected by pin shaft with cord clip 11, cord clip 11 clamps drag-line 3 by bolt 7.
The utility model is directed to the purlin structure of rigid roofing Cable dome, has the advantage that compared with prior art
(1) adjustable support rod is set between purlin and drag-line, can reduce the span of purlin.
(2) prestressing force can be applied to purlin by adjusting adjustable support rod length, the carrying of purlin can be effectively improved
Power realizes the biggish roof load in lesser section.
(3) between purlin and drag-line by adjustable support rod be connected after, can make roof purline cooperateed with main structure by
Power enhances the globality of roof structure, improves the stability of roof structure.
(4) elongate or shorten adjustable support rod by the way of turnbarrel, prestress application mode is easy, is easy to grasp
Make.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
The string branch purlin being applied in rigid roofing cable dome structure of the utility model, including purlin 1, for connecting purlin
Node 4 on the strut of item 1 and rigid roofing Cable dome drag-line 3, is fixed with rest 5 on strut on node 4, and two rest 5
A purlin 1 is supportted, the string branch purlin further includes at least one adjustable support rod 2, one end of adjustable support rod 2 and purlin 1
It is fixedly connected, the other end is fixedly connected with drag-line 3, and the length of adjustable support rod 2 can be adjusted.
In actual implementation, rest 5, then the mounting purlines 1 between two rests 5 are first installed on strut on node 4.It can
It adjusts 2 upper end of strut to be connected with purlin 1, lower end and drag-line 3 are to even.Finally, the length of adjustment adjustable support rod 2 is come to purlin 1
Apply prestressing force.(Fig. 1,2)
The connection type of adjustable support rod 2 and purlin 1 and drag-line 3 specifically: 2 upper end of adjustable support rod by pin shaft 6 with
Purlin 1 is connected；2 lower end of adjustable support rod is connected by pin shaft 6 with cord clip 11, and cord clip 11 clamps drag-line 3 by bolt 7, thus
Realize the connection of adjustable support rod 2 and drag-line 3.(Fig. 3)
Adjustable support rod 2 divides for two sections, is connected by sleeve 8, the end of two sections and sleeve inner have direction
Opposite screw thread 9.When prestress application, extend adjustable support rod 2 with the tools such as spanner turnbarrel 8, when adjustable support rod 2
When stretch value setting value, pin 10 is inserted into the reserved hole of sleeve with fixes sleeve position.
