Concrete filled steel tube inclined strut structure.
Background technology
Most of large-scale cooling stack uses reinforced concrete structure, also has minority to use steel construction.Due to by
The limitation of construction level and construction equipment etc., the inclined strut of cooling stack largely use reinforced concrete cast-in-situ knot
Structure, also there is minority to use armored concrete precast construction, steel construction or concrete filled steel tube.
It is such as high-order to receive water cooling tower, indirect air cooling cooling tower for the higher cooling stack of air intake open height,
In order to reduce the slenderness ratio of inclined strut rod member, supporting the inclined strut of tower, circumferentially generally use intersects triangular system (such as X branch
Post etc.), along radial direction generally use larger sectional dimension (such as square-section, long round section etc.；Section length direction is along footpath
To arrangement).
Influenceed by inclined strut section length direction size, the wall thickness of cooling tower tower bottom is generally larger.In addition, ought tiltedly it prop up
When post uses concrete filled steel tube, in order to remain to keep transversal under higher steel pipe inner concrete perfusion lateral pressure effect
The shape in face, the outside steel pipe of on-circular cross-section steel core concrete column need using larger wall thickness and set complicated inside drawknot
Measure.
In view of the design of industrial cooling stack, construction present situation, it is necessary to propose a kind of Novel cooling tower inclined strut
Structure, meeting the requirement of cooling tower inclined strut rod member slenderness ratio and be resistant to the premise of higher steel pipe inner concrete perfusion lateral pressure
Under, reduce the length direction size of pillar cross section, and reduce the wall thickness of outside steel pipe.
Utility model content
To solve the shortcomings of the prior art, the utility model provides a kind of cooling stack steel tube concrete
Native inclined strut structure；The inclined strut structure can meet the requirement of cooling tower inclined strut rod member slenderness ratio and be resistant to higher steel pipe
Reduce the length direction size of inclined strut cross section on the premise of inner concrete perfusion lateral pressure and reduce the wall thickness of outside steel pipe.
To achieve the above object, the utility model takes following technical solution：
A kind of cooling stack concrete filled steel tube inclined strut structure, including the concrete filled steel tube that more Pin are circular layout
Intersect inclined strut, and intersect per Pin concrete filled steel tubes and be connected at the top of inclined strut with the broadening platform of circular ring structure, bottom and cooling
Tower ring group connects；It is to fix after-pouring coagulation by two cross one another circular section steel pipes to intersect inclined strut per Pin concrete filled steel tubes
Soil forms steel tube-concrete combined structural；The infall that described concrete filled steel tube intersects inclined strut is provided with vertical supporting post,
Described vertical supporting post is connected by support column buttress with cooling tower ring group.
Also include the horizontal ring beam of intercolumniation, the horizontal ring beam of intercolumniation provides lateral Displacement for cooling tower inclined strut；Intercolumniation horizontal loops
Beam intersects inclined strut with all concrete filled steel tubes and is connected, and is arranged on the infall that concrete filled steel tube intersects inclined strut.
Support column buttress is radially arranged along cooling tower ring group.
Described vertical supporting post intersects the one-to-one arrangement of inclined strut or arranged for interval with concrete filled steel tube.
Described vertical supporting post is solid post or open tubular column, and solid post uses concrete filled steel tube or armored concrete knot
Structure；Vertical supporting post is perpendicular to the ground or tilts.
Described concrete filled steel tube intersects passes through weldering between inclined strut, vertical supporting post, support column buttress, cooling tower ring group
Connect, cast-in-place mode connect it is integral.
Intersect inclined strut bottom per Pin concrete filled steel tubes and be provided with cooling tower inclined strut post bottom buttress, cooling tower inclined strut leads to
Post bottom buttress is crossed to be fixedly connected with cooling tower ring group.
It is X-type structure that described concrete filled steel tube, which intersects inclined strut,.
Described broadening platform inboard root is connected with intersecting inclined strut capital or cooling tower tower bottom.
The utility model compared with prior art, has advantages below：The utility model is by the steel tube concrete that is circular layout
Soil intersects inclined strut composition, small using the steel pipe cross-fixing of circular section, thickness of steel pipe；So that the length direction of inclined strut cross section
Size is small, and inclined strut cross sectional dimensions is small, tower wall thickness is thin；And inclined strut is intersected to concrete filled steel tube by vertical supporting post and entered
Row Auxiliary support is strong to the filling concrete lateral pressure tolerance in steel pipe；Without complicated inside box construct, construction party
Just；And low engineering cost.
The utility model also expansible technological improvement applied to conventional steel bar concrete cooling stack, it is therefore an objective to
Reduce the cross sectional dimensions of armored concrete inclined strut, increase inclined strut radial rigidity, so as to reduce inclined strut deadweight, reduce steel
Reinforced concrete inclined strut construction false form support system, it is convenient to build construction.Now, circular cross-section steel pipe concrete inclined strut replaces
It is changed to square-section or circular cross-section steel reinforced concrete inclined strut, the design principle of vertical support column and the horizontal ring beam of intercolumniation is constant.
Further, horizontal ring beam is set more really to meet to protect the mechanical requirements that concrete filled steel tube intersects inclined strut, but
It is to set or do not set the horizontal ring beam of intercolumniation to be determined according to the mechanical requirements of actual support.When vertical supporting post is with intersecting inclined strut
It can not set intercolumniation horizontal ring beam during one-to-one setting, intercolumniation horizontal ring beam should be set during arranged for interval.
