Description
Technical field
The utility model relates to wind-powered electricity generation field, in particular to a kind of foundation ring of wind generating set.
Background technique
Currently, be to adapt to low wind speed power generation needs, long diameter, big blade new architecture continue to bring out, this directly results in wind
Fatigue load is caused to dramatically increase, traditional basic ring type blower foundation causes because being unable to satisfy the increased demand of fatigue load
Concrete prematurely fails with steel base interannular interface and loosens and wave, serious that tower is caused to tilt and can not normally make
With causing great economic loss.
Traditional blower foundation ring wears annular distance up and down often by setting and wears ring reinforcing bar guarantee concrete and steel base
The connection of plinth interannular, shear behavior is limited between interface, can still deal in the case where charming appearance and behaviour fatigue load is little, but with new machine
The emergence of type, the increase of fatigue load, fatigue life then significantly reduce, and basic failure accidents continue to bring out, and are owner
Biggish economic loss is caused, this shows that traditional foundation ring needs to improve.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides the wind-force that a kind of structure is simple, interface shearing-resistance performance is good
Generating set foundation ring.
The technical solution that the utility model solves the above problems is: a kind of foundation ring of wind generating set, including steel base
Plinth ring, foundation ring inside and outside wall are equipped with high performance concrete preform strip band, set stack shell peg, stack shell on steel base ring inside and outside wall
Peg one end is weldingly fixed on steel base ring, and the other end is poured through high performance concrete preform strip band and exposed with scene
Normal concrete is built to be attached.
Above-mentioned foundation ring of wind generating set, the stack shell peg are vertically uniformly distributed along the inside and outside wall of steel base ring.
Above-mentioned foundation ring of wind generating set, stack shell peg one end are welded on foundation ring, and the other end exposes high property
The length of the concrete prefabricated band of energy is 100 ~ 200mm, and is attached with cast in situs normal concrete.
Above-mentioned foundation ring of wind generating set, the prefabricated strip width of high performance concrete are 100mm.
Above-mentioned foundation ring of wind generating set, the prefabricated swath height of high performance concrete and the embedment of steel base ring are mixed
Height in solidifying soil is equal.
The utility model has the beneficial effects that: the utility model is equipped with the high property of annular on steel base ring inside and outside wall
Can concrete prefabricated band, by using the first prefabricated package foundation ring of high performance concrete, and stack shell peg and common mixed is set
Solidifying soil carries out live one-piece casting, can greatly increase the shear stiffness at interface between foundation ring and concrete in this way, reduces peak
It is worth stress, improves anti-fatigue ability between interface, effectively increase blower fatigue life, extends blower service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the secondary schematic diagram poured in the utility model scene.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of foundation ring of wind generating set, including steel base ring 1, inside and outside the steel base ring 1
Wall, which is equipped with high performance concrete preform strip band 2, not only can effectively guarantee concrete construction quality because being prefabrication, and
And can effectively increase the shear behavior between steel base ring 1 and concrete, anti-fatigue performance between interface is improved, and then effectively
Avoid the charming appearance and behaviour fatigue damage of concrete.
2 width of high performance concrete preform strip band be 100mm, height in 1 Transducers Embedded in Concrete of steel base ring
Height it is equal.
Vertical uniformly distributed stack shell peg 3 on 1 inside and outside wall of steel base ring, 3 one end of stack shell peg is welded on steel
On foundation ring 1, the other end runs through the high performance concrete preform strip band 2 and exposed 100 ~ 200mm, with guarantee and cast in situs
Normal concrete 4 effectively connects.
The setting of the stack shell peg 3 can increase between steel base ring 1 and high performance concrete preform strip band 2, is high
Interfacial bond property between performance concrete preform strip band 2 and cast in situs normal concrete 4 improves anti-shear concrete fatigue energy
Power increases service life of fan.It can also enhance between prefabricated high performance concrete and cast in situs normal concrete 4 simultaneously
Switching performance guarantees the co-operation between new-old concrete, avoids disengaging between two kinds of materials.
1 periphery high performance concrete preform strip band 2 of steel base ring is transported again after wrapping up and conserve in advance to scene,
The construction quality that can fully ensure that high performance concrete in this way, avoid cast-in-place concrete it is that may be present vibrate leakiness and
Gradation equal construction quality problems not up to standard.
The work progress of the utility model is as follows: as shown in Fig. 2, first in 1 Transducers Embedded in Concrete section of steel base ring
Stack shell peg 3 is evenly arranged according to calculating respectively on outer wall, 3 length requirement of stack shell peg runs through high performance concrete preform strip band
Exposed 200mm or so after 2, to ensure the quality of connection between cast-in-site normal concrete.Then in factory by steel base
1 Transducers Embedded in Concrete section inside and outside wall of ring uses high performance concrete preform strip band 2 to wrap up in advance respectively, is transported to again after conserving 28 days
Scene carries out second pouring；Finally pour at the scene, the normal concrete of after-pouring by stack shell peg 3 ensure with it is previous prefabricated
2 part of high performance concrete preform strip band carry out good connection, it is ensured that pouring quality.
