Description
Technical field
The invention belongs to Structural Engineering long strands field, more particularly to a kind of batter post couples stress with wide span house cap
Structure.
Background technology
With a large amount of constructions of large span spatial structure, building is sent out towards complicated, the vdiverse in function comprehensive direction of build
Exhibition, architect has been not content with the shape of rule, larger span, or even is not content with and only makes an issue of in the plane, examines
Consider the aesthetic effect on facade, so that batter post component is by bold utilization, but batter post overall structure produces outside power of toppling
Square, weakens integrally-built integral rigidity, while oblique pillar causes larger post bottom moment of flexure and horizontal thrust to basis.Such as
What reduces the tilting moment that batter post is produced to overall structure, and increase is contributed integrally-built integral rigidity, and is reduced to base
Larger post bottom moment of flexure and horizontal force that plinth is caused, while ensureing batter post degree of safety again, increase ductility, improve safety stock,
It is the problem of needing in engineering to solve.
The content of the invention
The present invention relates to the structure that a kind of batter post couples stress with wide span house cap, the thickness of wide span house cap is reduced,
The tilting moment that batter post is produced to overall structure is reduced, batter post is added and integrally-built integral rigidity is contributed, also simultaneously
Larger post bottom moment of flexure and horizontal force that batter post is caused to basis are reduced, structure ductility is added, improves the reliable of structure
Property.
The structure that a kind of batter post couples stress with wide span house cap is made up of wide span house cap, batter post, right cylinder, described
Wide span house cap be large span steel truss, be made up of plane girder, space truss, plane girder include main couple, jack truss,
Space truss includes outer ring annular stereo truss and internal straight across space truss composition, and the ring truss and inside are straight across three-dimensional purlin
Frame is inverted triangle space truss, and described peripheral batter post is formed by hypomere steel reinforced concrete batter post and epimere steel batter post, described
Hypomere steel reinforced concrete column length accounts for 1/5th of whole peripheral batter post length, and epimere steel batter post accounts for whole peripheral batter post length
4/5ths, the right cylinder be uiform section reinforced column.The large span steel truss and uiform section armored concrete are straight
Post is connected by hinged-support, and the large span steel truss is connected with batter post by bridle iron.The batter post and right cylinder pass through
Long-span roof forms the structure that a kind of batter post couples stress with long-span roof.A kind of batter post coupled with wide span house cap by
The structure erection sequence of power is then pacified to set up peripheral batter post hypomere, batter post epimere and right cylinder and internal framework successively
Wide span house cap is filled, the internal framework and right cylinder reach intensity rear collapsible die, and the outer shroud batter post need to be in large span
Just collapsible die after steel worm-gearing is installed completely.
Further, the lower ear plate of the hinged-support is connected with uiform section armored concrete capital slugging, the hinge
The upper ear plate of bearing is with the lower boom on wide span house cap ring truss by being welded to connect, and the upper ear plate passes through pin with lower ear plate
Axle is connected.
Further, the main couple top boom of the wide span house cap with jack truss top boom by mutually passing through steel node weld
Connection, the main couple lower edge and jack truss lower edge are connected by mutually passing through steel node weld.The main couple winds up and ring truss
Wind up and connected by mutually passing through steel node weld, the main couple lower edge meets node weld company with ring truss lower edge by mutually passing through steel
Connect, the jack truss winds up to wind up with ring truss and is connected by mutually passing through steel node weld, and the jack truss lower edge passes through two circles
Steel pipe is welded to connect with ring truss lower edge.
Beneficial effect
（1）The batter post is when without wide span house cap, and batter post is equivalent to cantilever batter post, it is impossible to independently undertake load, to foundation
Into larger post bottom moment of flexure and horizontal force, larger tilting moment is produced to overall structure, at the same batter post capital produce it is larger
Displacement, much larger than the capital limit displacement value of code requirement.When batter post and right cylinder by long-span roof form a kind of batter post with it is big
During the structure of across roof system coupling stress, wide span house cap forms a sidewise restraint to batter post capital, by the displacement of batter post capital
Very little is reduced to, the capital limit displacement value of code requirement is met.
So that batter post significantly reduces to the tilting moment that overall structure is produced, the relatively huge pillar bottom moment of flexure that is caused to basis and
Horizontal force also accordingly reduces.Simultaneously because sidewise restraint of the wide span house cap to batter post capital so that batter post can undertake roofing
The vertical load transmitted, now batter post is while also serve as a strong point of wide span house cap, this coupling stress so that
Truss top-bottom chord between right cylinder and batter post is in tension state, reduces truss member section and thickness.
（2）The structure that a kind of batter post couples stress with wide span house cap not only meets architectural appearance requirement, also carries
The high safety and reliability of total.
（3）Standard construction form is provided, facilitates engineers and technicians to use.

Embodiment
By taking certain stadium project as an example, to illustrate that the batter post of the present invention couples the structure of stress with wide span house cap.
Set up peripheral batter post hypomere 7, batter post epimere 6 and right cylinder 9 successively first, wherein integral planar is ellipse, week
Enclosing batter post, totally 52 and ground angle are 50 ° or so, in diverging, as shown 1, diagram 2, diagram 3.And internal framework
16, as shown 4, internal framework 16 and right cylinder reach intensity rear collapsible die, and outer shroud batter post 8 need to be in long-span steel roof 5
Rear collapsible die is installed completely.Wherein batter post is put on when only individually being calculated with substructure using roof system as load
Batter post top, capital displacement is 125mm to the maximum, when the overall calculation together with wide span house cap, takes corresponding measure by batter post and big
During across roof system coupling stress, capital displacement is 36.3mm to the maximum.Maximum horizontal displacement limit value in capital as defined in specification is that batter post is high
51 percent, threshold limit value is 75mm in this project.
Hold-down support 11 is then installed on batter post top, then outer collarette truss 3, periphery are installed on hold-down support 11
The erection sequence of ring truss 3 is that Liang Ge fitting-up gangs install since the peak of gymnasium, is symmetrically installed successively from periphery from high to low
