Abstract
The utility model discloses a kind of foundation ring of wind generating set, including cylinder and it is arranged in the upper flange and lower flange at its two ends, multiple PBL shear connectors are evenly equipped with the inner and outer wall of the cylinder respectively, it is connected as a single entity, is connected as a single entity between each PBL shear connectors on cylinder outer wall by the outer stirrup ring through circular hole by the interior stirrup ring through circular hole between each PBL shear connectors on cylinder inner wall.Foundation ring forms shear-pin after casting concrete between foundation ring and concrete, effectively upper load uniformly can be delivered in the concrete of periphery, it is to avoid the localized crush of compressive region concrete and drawing crack, it is to avoid blower fan gene basis ring is damaged and produces and waves.Each PBL shear connectors are connected as a single entity by stirrup ring simultaneously, effectively to improve the bonding of cylinder and concrete interface, it is to avoid the disengaging of concrete and cylinder, the anti-shearing antifatigue ability of whole foundation ring are also improved.
Description
Technical field
The utility model is related to a kind of foundation ring, more particularly to a kind of foundation ring of wind generating set.
Background technology
Currently, with a large amount of construction of land blower fan, its accident resulting from poor quality of projects happens occasionally.Wherein most engineering things
Therefore come under long-term wind action, foundation ring concrete is (due to construction reason, the quality of Surface layer's concrete near main wind direction
It is often poor) easily there is drawing crack or localized crush, gap is formed, causes blower fan to wave.And traditional blower foundation ring is not
Take into full account blower foundation destruction can the energy waved to the local drawing crack and conquassation of Surface layer's concrete, blower fan and fatigue influence,
Do not take effective measures the drawing crack for reducing concrete or localized crush constructively and improve the ability of blower fan antidumping.If
Waving blower fan cannot be handled in time, be elapsed over time, because of accumulation shock effect and rain erosion, foundation ring prevailing wind direction periphery
The conquassation of concrete and cracking constantly outwardly and downwardly extend, and blower fan, which is waved, to be continued to increase.Once the damage of Surface layer's concrete to
Under when extending to certain depth, blower fan will be changed into local lever stress form at 2 points by former overall stress, when being used as lever
The foundation ring lower flange top concrete conquassation of fulcrum, blower foundation easily collapses, so as to influence the safety of whole unit and use
Life-span.
Utility model content
The purpose of this utility model is that providing a kind of tension for reducing concrete splits and prevent localized crush and improve wind
The foundation ring of wind generating set of machine resistance to capsizing.
This foundation ring of wind generating set that the utility model is provided, including cylinder and the upper method for being arranged in its two ends
Each PBL being evenly equipped with respectively on multiple PBL shear connectors, cylinder inner wall on blue and lower flange, the inner and outer wall of the cylinder is cut
It is connected as a single entity between power key by the interior stirrup ring through circular hole, by through circle between each PBL shear connectors on cylinder outer wall
The outer stirrup ring in hole is connected as a single entity.
In order to increase the adhesive property between foundation ring and concrete, improve on resistance to capsizing, the inwall for making the cylinder
PBL shear connectors and outer wall on PBL shear connector interlaced arrangements.
In order to ensure that concrete slurry is effectively entered, it is rectangular steel plates to make the PBL shear connectors, thereon along its length
The circular hole penetrated is evenly equipped with, the spacing between circular hole and cylinder barrel is more than the diameter of concrete coarse aggregate.
In order to increase shear resistance, the interior stirrup ring is set to be welded successively by multi-section circular arc reinforcing bar with the outer stirrup ring
Form.
The utility model makes foundation ring after casting concrete, base by setting PBL shear connectors on the cylinder of foundation ring
Shear-pin is formed between plinth ring and concrete, effectively upper load uniformly can be delivered in the concrete of periphery, it is to avoid by
The localized crush of compressive concrete and drawing crack, it is to avoid blower fan gene basis ring is damaged and produces and waves.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of one preferred embodiment of the utility model.
Fig. 2 is the schematic top plan view (being free of upper flange) of this preferred embodiment.
Illustrate sequence number：
1-upper flange, 2-cylinder, 3-lower flange, 4-PBL shear connectors, 5-interior stirrup ring, 6-outer stirrup ring.
Embodiment
As shown in Figure 1 and Figure 2, the present embodiment provide this foundation ring of wind generating set, including upper flange 1, cylinder 2,
Lower flange 3, PBL shear connectors 4, interior stirrup ring 5 and outer stirrup ring 6, cylinder 2 are steel cylinder.
PBL shear connectors 4 are to be evenly equipped with five circular holes along its length (according to reality on rectangular steel plates, each PBL shear connectors
Border situation selects the quantity of circular hole), it is evenly arranged respectively on the inner and outer wall of cylinder and is fixed with multiple PBL shear connectors, and it is interior
PBL shear connector interlaced arrangements on PBL shear connectors and outer wall on wall, cause compressive region coagulation by the setting of PBL shear connectors
Native part resistance to compression is burst and the ability of anti-drawing crack is guaranteed, and also increases the adhesive property between foundation ring and concrete, improves
Resistance to capsizing.
Interior stirrup ring and outer stirrup ring are the ring-shaped stirrup by multi-section circular arc reinforcement welding, to ensure stirrup itself
Anti-shearing ability.Interior stirrup ring and outer stirrup ring respectively have in five (quantity that stirrup ring is selected according to actual conditions), five
Stirrup ring is arranged along cylindrical barrel direction, is each passed through the circular hole at each PBL shear connectors sustained height position on inwall, is made circle
Each PBL shear connector of cylinder inwall is connected as a single entity；Five outer stirrup rings are arranged along cylindrical barrel direction, are each passed through outer wall
Circular hole at upper each PBL shear connectors sustained height position, makes each PBL shear connector of cylinder outer wall be connected as a single entity；With effective
Improve the bonding of cylinder and concrete interface, it is to avoid the disengaging of concrete and cylinder, also improve whole foundation ring anti-shearing anti-
The ability of fatigue.The spacing between spacing, outer stirrup ring and cylinder outer wall between interior stirrup ring and cylinder inner wall is all higher than mixing
The diameter of solidifying soil coarse aggregate, situation not in place is poured to ensure that aggregate effectively enters to avoid the occurrence of in foundation ring,
Ensure the intensity and reliability of foundation ring.
