Space truss includes that outer ring annular stereo truss and inside are constituted straight across space truss, and the ring truss and inside are straight across three-dimensional purlin
Frame is inverted triangle space truss, and the peripheral batter post is formed by lower section steel reinforced concrete batter post and upper section steel batter post, described
Lower section steel reinforced concrete column length accounts for 1/5th of entire peripheral batter post length, and upper section steel batter post accounts for entire peripheral batter post length
4/5ths, the right cylinder be cross-section reinforced column.The large span steel truss and cross-section armored concrete are straight
Column 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 successively to establish peripheral batter post lower section, batter post upper section and right cylinder and internal framework, is then pacified
Wide span house cap is filled, the internal framework and right cylinder reach intensity rear collapsible die, and the outer ring batter post need to be in large span
Steel worm-gearing just collapsible die after the installation is completed completely.
Further, the lower ear plate of the hinged-support is connect with cross-section armored concrete capital slugging, the hinge
The upper ear plate of support and the lower boom on wide span house cap ring truss pass through pin by welded connecting, the upper ear plate and lower ear plate
Axis connection.
Further, the main couple top boom of the wide span house cap and jack truss top boom pass through Xiang Guangang node weld
Connection, the main couple lower edge are connected with jack truss lower edge by Xiang Guangang node weld.The main couple winds up and ring truss
It winds up and is connected by Xiang Guangang node weld, the main couple lower edge and ring truss lower edge connect node weld by Xiang Guangang and connect
It connects, the jack truss winds up to wind up with ring truss and be connect by Xiang Guangang node weld, and the jack truss lower edge passes through two circles
Steel pipe and ring truss lower edge are welded to connect.
Beneficial effect
(1) for the batter post when no wide span house cap, batter post is equivalent to cantilever batter post, load cannot be independently undertaken, to base
Biggish column bottom moment of flexure and horizontal force caused by plinth generate biggish tilting moment to overall structure, while batter post capital generates
Larger displacement, much larger than the capital limit displacement value of code requirement.When batter post and right cylinder form a kind of batter post by long-span roof
When coupling the structure of stress with long-span roof, wide span house cap forms a sidewise restraint to batter post capital, by batter post capital
Displacement is reduced to very little, meets the capital limit displacement value of code requirement.
So that batter post significantly reduces the tilting moment that overall structure generates, caused by basis compared with huge pillar bottom moment of flexure and
Horizontal force also accordingly reduces.Simultaneously because sidewise restraint of the wide span house cap to batter post capital, enables batter post to undertake roofing
The vertical load transmitted, batter post is simultaneously also as a supporting point of wide span house cap at this time, 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) structure that a kind of batter post couples stress with wide span house cap not only meets architectural appearance requirement, also mentions
The high safety and reliability of total.
(3) standard construction form is provided, engineers and technicians is facilitated to use.
