Description

A kind of hybrid grid cylinder that can improve bundle pillar unstability load
Technical field
This utility model relates to technical field of structural engineering, particularly relates to a kind of novel hybrid grid cylinder, particularly relates to one Plant the hybrid grid cylinder that can improve bundle pillar unstability load.
Background technology
As the load-carrying construction of vertical load, hyperboloid or cylinder mesh cylinder due to its profile attractive in appearance and good penetrating effect Really, engineer applied is the most in recent years.Most typical genus animation museum of China and Guangzhou New TV Tower, the former adopts With hyperboloid network cylinder, the latter have employed rigidity direction the three-way grid cylinder of notable difference.
Either hyperboloid mesh cylinder or cylinder mesh cylinder, in vertical load (gravity laod) and moment of flexure (wind or earthquake) Under effect, cylinder overall collapse will not occur more greatly due to its planar dimension, but the large area face of cylinder local easily occurs Outer unstable failure, referred to as bundle pillar unstability.Owing to cylinder peripheral member (grid posts) is radially without any horizontal support, group During post unstability, unstability load is relatively low, is the main cause of restriction mesh cylinder structure design economy.
The bundle pillar unstability load of mesh cylinder has substantial connection with its height and diameter, along with the increase of mesh cylinder block dimension, spy It not that planar dimension increases its bundle pillar unstability load and will drastically decline, thus need to increase outside mesh cylinder for meeting requirement for bearing capacity Enclose the size of component (grid posts), but this will reduce the permeability of mesh cylinder structure, and design economy is poor.
In view of the situation, seek vertically to carry more efficiently, to design more cost effective mesh cylinder pattern be structure work to structure The task of top priority of journey circle.It will be apparent that only from changing the grid pattern of cylinder or increasing web thickness, be a kind of waste Material and the method little to vertical bearing capacity raising, thus in terms of structural style and structural system, to seek solution party Case.
Utility model content
For improving load-carrying efficiency and the design economy of mesh cylinder structure, the utility model proposes one and can improve bundle pillar The hybrid grid cylinder of unstability load.Described hybrid grid cylinder includes: steel lattice cylinder, outer press ring, prestressed cable dish and space Oblique radiation prestressed cable;Described outer press ring is arranged along short transverse multiple tracks according to the actual requirements, is embedded in described steel mesh In lattice cylinder;Described prestressed cable dish is placed on described steel lattice cylinder shaft core position, and wrong with described outer press ring along short transverse Position is arranged;Described space oblique radiation prestressed cable is oblique to be connected between described outer press ring and described prestressed cable dish.
In above-mentioned hybrid grid cylinder, described steel lattice cylinder includes: grid posts and ring beam;Described grid posts along two to intersection Arrange, composition cylinder or hyperboloid grid barrel shell;Described ring beam is arranged on top and the bottom of described steel lattice cylinder, respectively It is connected with top and the bottom of described grid posts.Described steel lattice cylinder is also in the downside of top ring beam and the upside of bottom ring beam The most circumferentially it is uniformly arranged 8 otic placodes to be articulated and connected with corresponding described space oblique radiation prestressed cable.
In above-mentioned hybrid grid cylinder, described outer press ring includes: annular girder, connection short column and otic placode;Multiple described connections Short column is arranged on the periphery wall of described annular girder to be welded to connect with corresponding grid posts;Described otic placode is in described annular girder Side arrange the most symmetrically 8 with the corresponding described space hinged company of oblique radiation prestressed cable Connect.
In above-mentioned hybrid grid cylinder, described prestressed cable dish includes: stem stem, ring flat-plate and otic placode;Described stem stem is arranged on The center of described prestressed cable dish;The middle part of described stem stem it is enclosed within outside described ring flat-plate;Described otic placode is in the periphery of described stem stem The upper and lower sides of wall arranges 8 the most symmetrically to cut with scissors with the corresponding oblique radiation in described space prestressed cable Connect in succession.
In above-mentioned hybrid grid cylinder, the two ends of the oblique radiation in described space prestressed cable are respectively provided with fork ear with relative The otic placode being arranged on described ring beam, outer press ring and prestressed cable dish answered is articulated and connected.
The novel hybrid grid cylinder that can significantly improve bundle pillar unstability load that the utility model proposes, be additionally arranged in inside by The rope support system of outer press ring, prestressed cable dish and space oblique radiation prestressed cable composition, the hybrid grid so formed Cylinder possesses following advantage:
(1) can effectively prevent mesh cylinder generation bundle pillar unstability, improve mesh cylinder bundle pillar unstability lotus under vertical uniform load q Carry.The rope support system being made up of outer press ring, prestressed cable dish and space oblique radiation prestressed cable, in the horizontal direction Being equivalent to embedded in several rung formula rigid disks along short transverse inside mesh cylinder, being applied with prestressed drag-line can Effective constraint and the out-of-plane deformation coordinating grid posts, and then stop the appearance of bundle pillar Failure Model.
(2) anti-side rigidity and the bearing capacity of mesh cylinder can be effectively improved.Traditional double curved surface steel network lattice cylinder or cylinder steel Mesh cylinder bearing mechanism under the horizontal loads such as wind, earthquake is similar to cantilever mast, and its anti-side rigidity is with bearing capacity relatively Weak.And described hybrid grid cylinder, set up inside it by outer press ring, prestressed cable dish and space oblique radiation prestressing force The rope support system of drag-line composition, collectively constitutes firm girder system with peripheral meshes cylinder, it is possible to notable in vertical plane Improve the anti-side rigidity of mesh cylinder and bearing capacity.Owing to drag-line is applied with the prestressing force of certain level, can guarantee that this Girder system is in normal operating conditions all the time, will not deactivate owing to the deformation of steel lattice cylinder makes rope lax.
(3) mesh cylinder sensitivity to geometry initial imperfection can be effectively reduced.Traditional double curved surface steel network lattice cylinder or cylinder Steel lattice cylinder is under vertical load or horizontal loads, and grid posts is in vertical pressured state, and bundle pillar unstability is to cylinder Initial geometrical defect has bigger sensitivity;Set up inside mesh cylinder by outer press ring, prestressed cable dish and Space Oblique To the rope support system of radiation prestressed cable composition, it is possible to the effective local deformation retrained and coordinate grid posts, thus pole The earth reduces the mesh cylinder sensitivity to geometry initial imperfection, and then prevents sending out too early of mesh cylinder bundle pillar Failure Model Raw.
(4) economy and the reasonability of structural system are improved.Traditional double curved surface steel network lattice cylinder or cylinder steel lattice cylinder are by increasing The sectional dimension of big grid posts, improves bending rigidity and the anti-bending bearing capacity of grid posts, and then reaches to reduce outside mesh cylinder face Deformation, the purpose of raising bundle pillar unstability load.And the hybrid grid cylinder that the utility model proposes is retrained by prestressed cable The out-of-plane deformation of mesh cylinder, utilization is axial rigidity and the axial bearing capacity of prestressed cable, has compared to component bending resistance More direct binding effect and higher stock utilization, thus be the most more economical structural system.
