Description
Technical field
The invention belongs to power plant cooling tower design field, be specifically related to a kind of tension structure cooling tower.
Background technology
Cooling tower in power plant typically uses reinforced concrete structure, and this structural shape is through years of researches and reality
Trampling, and be applied in a large amount of engineerings, diameter of the most can having designed and constructed, more than 150m, highly reaches the super large of about 200m
Concrete Cooling Water Tower；Concrete Cooling Water Tower operating expenses is higher, and the cycle is longer, and steel structure cooling tower has the excellent of short construction period
Gesture, for the Accelerating The Construction cycle, along with the development of long strands, this new structure pattern of steel structure cooling tower also will become industry
A main selection, but steel structure cooling tower rigidity and stability are not as Concrete Cooling Water Tower, and cost is higher, the most further
Reducing the cost of steel structure cooling tower, steel structure cooling tower could commercially occupy certain share.
In power generating plant cooling tower use rung formula tension structure cooling tower, it is possible to reduce steel structure cooling tower use steel
Amount, thus reduce the cost of steel structure cooling tower.The feature of rung formula tension structure is: with quantity of material is few but rigidity big, stable
Property high, rung formula tension structure is applied in cooling tower, owing to rung formula tension structure is horizontal positioned in cooling tower, cold
But the rigidity in tower horizontal plane and stability are improved, i.e. rung formula tension structure only improve only the horizontal loops of cooling tower
To rigidity and stability, cooling tower is space structure, improves the vertical of cooling tower and lateral rigidity the most further, is rung formula
The problem that tension structure cooling tower needs to solve.
Skew lattice structure is vertical up to now and lateral rigidity and the best structural shape of stability.Oblique grid is tied
" Vladimir Grigoryevich Shu Huofu (1853-1939), he is acknowledged as " Russia Supreme Being to structure inventor
First engineer of state ", the most still there is original and different " Shu Huofu " hyperbolic much stood erect in the big ground of Russia
Shell tower, the structure that these towers use is exactly skew lattice structure.One of the most outstanding building great master, " High-Tech " represent
Personage, the Pritzker Architecture Prize (this prize is acknowledged as building the Nobel Prize on boundary) winner in 1999, the promise graceful Foster rank of nobility
Scholar's (nineteen thirty-five-) thinks: Shu Huofu is my tutor, and " Shu Huofu " hyperbolic shell tower of teacher's Shu Huofu design is the " work of talent
Product ", many inspirations of his design are from teacher Shu Huofu.Within 2014, the Pritzker Architecture Prize winner Japanese Architects Ban Mao sets
The highest paper tower of meter, is also the skew lattice structure pattern used.
To sum up, the vertical and lateral rigidity of the cooling tower of existing skew lattice structure pattern is good, but skew lattice structure
The problem that the cooling tower of pattern exists horizontal hoop rigidity and poor stability.
Summary of the invention
The present invention solves that the cooling tower of existing skew lattice structure pattern exists horizontal hoop rigidity and poor stability
Problem, and then provide a kind of oblique grid rung formula tension structure cooling tower.
The present invention solves that above-mentioned technical problem adopts the technical scheme that:
The oblique grid rung formula tension structure cooling tower of the present invention includes skew lattice structure 1 and multiple rung formula stretch-draw
Structure 2, the outer surface of described oblique grid rung formula tension structure cooling tower is provided with eyelid covering, erecting of skew lattice structure 1
Using oblique grid pattern to lateral, skew lattice structure 1 is made up of bidirectional crossed batter post cylinder；
Each rung formula tension structure 2 includes outer-ring beam 2-1, interior connection ring 2-2 and some drag-line 2-3, outer-ring beam 2-1 and
Interior connection ring 2-2 is donut, and one end of drag-line 2-3 is connected with outer-ring beam 2-1, and the other end of drag-line 2-3 is all connected with interior
Ring 2-2 connects, the centripetal setting of drag-line 2-3 or non-centripetal setting, drag-line 2-3 non-centripetal when arranging head and the tail be sequentially connected with, drag-line 2-3
Uniform being arranged between outer-ring beam 2-1 and interior connection ring 2-2, every layer of rung formula tension structure 2 constitutes rung shape, and every layer some
Drag-line 2-3 is provided with prestressing force, and multiple rung formula tension structures 2 are successively set on cooling tower 1 along the short transverse of cooling tower 1
On.
Described steel structure cooling tower also includes the vertical bar in center 3, and the rung formula ring beam 2 of each layer is centrally through the vertical bar in center
3 connect；
The eyelid covering of described steel structure cooling tower uses metal alloy plate, composite or membrane structure material, metal alloy plate
For Al-Mg-Mn alloy plate, titanium zine plate, aluminium sheet, compression color steel plate；
Composite is glass-reinforced plastic material, the weaving cloth that membrane structure material is is basic unit's coating polymer resin with fiber.
The method have the advantages that
The present invention uses skew lattice structure and rung formula tension structure composition oblique grid rung formula tension structure space
Stress system, uses metal alloy plate, non-metal composite board or membrane structure as the eyelid covering of cooling tower, and described cooling tower is by perpendicular
To the stress system of skew lattice structure and horizontal direction rung formula tension structure composition cooling tower, the coldest with existing
But tower is compared, and skew lattice structure uses the intersection batter post common beam column construction of replacement around cooling tower outer surface, forms cylinder, its
Stress form, based on axle power, can bear vertical load and can bear again horizontal loading, has upper side firm with vertical to rigidity
Degree, the cooling tower loading characteristic of the present invention has the difference of essence, and the present invention is by skew lattice structure and rung formula tension structure
Composition spatial mesh structure, cooling tower horizontal direction uses has higher rigidity and stability rung formula tension structure, vertically
Employing can bear vertical load can bear again horizontal loading and the skew lattice structure based on axle power, constitute have higher
The spatial mesh structure cooling tower of rigidity and stability；Further increase the rigidity of rung formula tension structure cooling tower and stablize
Property, the rigidity of cooling tower and stability improve more than 40%, thus further reduce the cost of cooling tower；
The present invention can apply in power plant, use the present invention rung formula steel latticed structures cooling tower, have from heavy and light,
The advantage that speed of application is fast, dealing with foundation is simple, comprehensive cost is low, seismic wind resistance is good.
