Description
Technical field
The utility model is related to power plant cooling tower design field, and more specifically it is a kind of intersection truss pattern
Steel structure cooling tower.
Background technology
Cooling stack is the important large-scale cooling facility in one of thermal power plant or nuclear power plant.Gravity-flow ventilation
The adoptable version of cooling tower has reinforced concrete structure and steel construction.Domestic traditional large cooling column is essentially all
Using armored concrete shell structure, but the development with air cooling technique and long strands, because steel construction is from heavy and light, intensity
High, in-site installation is simple, speed of application is fast, anti-seismic performance is strong and can save a large amount of cement and stone material, steel can all reclaim again
Using the advantages of, in recent years steel structure cooling tower also progressively at home start use.
The patent No. is that 201510490183.4 Chinese patent discloses a kind of hyperbola Double-level Reticulated Shell steel structure cooling tower,
This tower is made up of bottom lattice column, transfer truss and top tower Double-level Reticulated Shell.Because structural system is in tower bottom air inlet
, using discrete lattice inclined strut, all there is larger difference at place with the Double-level Reticulated Shell of top tower in quality and in rigidity, makes
Obtain structural stability and seismic wind resistance has weak link in air inlet, thus affecting the overall steady of steel structure cooling tower
Qualitative, and then it is unsuitable excessive to limit the utilization scale of steel structure cooling tower；Simultaneously as the fabrication and installation difficulty of lattice column
Greatly, and stability is affected significantly by column length, thus to limit steel structure cooling tower air intake open height unsuitable too high；In addition, this steel
The top tower Double-level Reticulated Shell of construction cooling tower is made up of horizontal plane truss and the orthogonal setting of vertical plane truss, due to tower
Outer shroud chord member and tower inner ring chord member are located at same level, so in order to avoid the rod member of vertical plane truss and horizontal plane
Angle between the rod member of truss too small and reduce structural stability and increase node manufacture difficulty, tower mother curvature of a curve should not mistake
Greatly, so leading to tower profile more fat, the wind area of tower and structural steel amount are all larger, the economy of steel structure cooling tower
Property is not good.

Specific embodiment
Describe performance of the present utility model below in conjunction with the accompanying drawings in detail, but they are not constituted to of the present utility model
Limit, only for example.Make advantage of the present utility model more clear and easy to understand by explanation simultaneously.
Refering to accompanying drawing understand: by hyperbolic-type tower, go along with sb. to guard him panel adopt die mould aluminium alloy plate as a example, as Fig. 1 to 5 institute
Show, a kind of steel structure cooling tower of intersection truss pattern it is characterised in that: include meridian to truss 1, ring truss 2, diagonal brace 3,
Building enclosure 4 and agent structure 5, wherein said meridian constitutes described master to truss 1 with described ring truss 2 and described diagonal brace 3
Body structure 5, described building enclosure 4 is arranged on the outside left of more than the air inlet of described agent structure 5.
Described meridian includes outer vertical chord member 11, interior vertical chord member 12, vertical diagonal web member 13 and vertical web member to truss 1
14, each chord member and web member are connected to described meridian by node and form stable triangular mesh into the plane of truss 1.
Described ring truss 2 includes outer horizontal chord member 21, interior horizontal chord member 22, ring diagonal web member 23, and with described meridian
Share described vertical web member 14 to truss 1, each chord member and web member consist of stably node in the plane of described ring truss 2
Triangular mesh.
Described meridian is circumferentially equally spaced centered on the ring center of circle of described agent structure 5 to truss 1 and is constituted son
Noon forms ring truss array, its levels ring to truss array, described ring truss 2 along the short transverse arrangement of agent structure
Determined to truss space according to horizontal chord pole length.To control the chord member length phase to truss and ring truss for the same layer meridian
When, and ensure the grid of the ectonexine chord member composition of agent structure 5 close to square, so that agent structure 5 stress is more
Uniformly.
Described meridian forms intersection truss system to truss 1 with described ring truss 2 perpendicular quadrature.I.e. ring truss 2
Plane perpendicular to horizontal layout from meridian to truss 1, it is to avoid when prior art ring truss is horizontally disposed, when tower bus is bent
When rate is larger, truss web is too small with the angle of chord member, and the power transmission of member system is not good, and at node, the presence of rod member welding is hidden
The deficiency of weld seam, thus having more preferable tower curvature adaptability, can make tower bus shrink faster to the tower heart, the tower bodily form is more
Thin, and then substantially reduce wind area and the structural steel amount of tower.
Described diagonal brace 3 is arranged in the internal layer chord member quadrilateral mesh of described agent structure 5, and described oblique in each grid
Support 3 joins end to end in big " x " type arrangement.So that the stable leverage space lattice of the intersection truss System forming of agent structure 5,
And in the diagonal brace 3 that " x " type is arranged greatly, more conventional " people " type arrangement is more uniformly stressed, and node stability more preferably, and solves well
Determine due to the diagonal brace asymmetric stress corruptions leading to node region supervisor no diagonal brace side up and down.
All member section patterns of described agent structure 5 select pipe or square tube, and being connected by between component is welded
Or bolt connection.
To truss 1, described ring truss 2 and described diagonal brace 3 land continuous cloth along described agent structure 5 to described meridian
Put.The knot being connected using transfer truss with top tower by discrete lattice column, bottom lattice column with prior art tower bottom
Structure arrangement is compared it will be apparent that simplifying version, and by structural finite element analysis, this intersection truss system steel construction is cold
But tower significantly improves stability and the wind resistance anti-seismic performance of structure compared with prior art steel structure cooling tower；Simultaneously as it is empty
Between grid continuous arrangement, the height of tower air inlet also can be unrestricted, and tower outer heat dissipation equipment arrangement is more flexible, thus more
Adapt in large-scale and superhuge steel structure cooling tower；Further, since the improvement of Horizontal Force of Bridge Substructure, air inlet component
Section and weight all reduce, and avoid making and the installation of the large scale special-shaped component such as lattice column, transfer truss, reduce construction
Installation difficulty.
By purlin support, main purlin, secondary purlin and panel composition, purlin support 41 is welded to connect described building enclosure with main structure 5, main
Purlin 42 is with bolts with purlin support 41, and the main purlin 42 of secondary purlin 43 is with bolts, and panel 44 is adopted with time purlin 43
Self threading pin connects；Described panel adopts metal pressing plate or ptfe film.Ensure air-tightness and the wind resisting stability of tower.
By calculating analysis shows, intersection truss pattern steel structure cooling tower reasonable stress, structural stability is high, and wind resistance resists
Shock stability is strong, and the advantage of steel using amount relatively province is applicable to large-scale and superhuge steel structure cooling tower.
Other unaccounted parts belong to prior art.
