Description
Technical field
The utility model relates to wind generator facility, particularly a kind of blower foundation piling bar and connected node regulated of changing steel work of being used for.
Background technology
Wind-power electricity generation is a green energy resource technology with fastest developing speed in the world, landwid electric field build fast-developing in, it has been observed that some restrictions that the land Wind Power Utilization is suffered, problems such as, noise pollution big as floor space.Oversea wind aboundresources, Oversea wind power generation are influenced by noise, birds and the less-restrictive of problem such as Electromagnetic Interference, and it does not take land land resources, does not relate to problems such as land acquisition.Have, the variation of marine wind speed with altitude is less again, does not therefore need to set up very high support tower, thereby can reduce the cost of offshore wind generating group.Also have, marine turbulence intensity is low, and sea level frictional force is less, and the fatigue load that acts on the wind power generating set reduces, thereby can prolong the application life of wind-powered electricity generation unit.
Because above plurality of advantages, the ocean will become a wind-power market that develops rapidly.Deposits in Eastern Coastal China depth of water 50m is vast with interior oceanic area, and it is very near apart from power load center (the flourishing power shortages of coastal economy district), full-fledged along with the offshore wind farm field technology, wind-powered electricity generation will become the important energy source source of Deposits in Eastern Coastal China area sustainable development.
Build the blower fan unit in east China shallow sea and intertidal zone, its base form has many difficulties if adopt existing pile foundation to add the concrete bearing platform mode: it is high that concrete is difficult for being transported to scene, long construction period, operating expenses height, comprehensive cost.In view of this, the base form that adopts many steel pipe piles to add to change steel work can overcome above-mentioned deficiency.The conversion steel work can be at produce in factory, be transported to the building site again, be connected with stake, so that this kind foundational system has is simple for production, transportation, easy for installation, difficulty of construction is low, the field Welding amount is little, and speed of application is fast, short construction period, be convenient to boisterous off time of construction at sea, advantage such as comprehensive benefit is good.But because can there be the deviation of plane and short transverse in stake after the construction at the scene, adopt the connection joints of steel structure form of bolt usually, very high to required precision, therefore can't adapt to the construction error of stake, can not satisfy connection request herein.If adopt field Welding to adapt to construction error, field condition then can't guarantee welding quality, can bring serious quality problems thus.
The utility model content
Task of the present utility model provides a kind of blower foundation piling bar and connected node regulated of changing steel work of being used for, it has solved a series of problems of above-mentioned existing in prior technology, blower foundation conversion steel work is connected with steel pipe pile by short column, and its connected node can be regulated.
Technical solution of the present utility model is as follows:
A kind of blower foundation piling bar and connected node regulated of changing steel work of being used for, it comprises steel pipe pile, blower foundation conversion steel work, it also comprises retaining collar and rest, the short column of basis conversion steel work inserts from the steel pipe pile top and forms the inner cased type connection in the steel pipe pile, retaining collar then is set on the short column, and retaining collar and short column and steel pipe pile rest weld together simultaneously;
Described steel pipe pile is connected with blower foundation conversion steel work by short column.
Perfusion high strength grout in the space between described short column and the steel pipe pile.
A kind of blower foundation piling bar that is used for of the present utility model has following major advantage with the connected node regulated of changing steel work:
1, the conversion steel work is connected with steel pipe pile by the utility model connected node, and the space three-dimensional can be regulated, and can adapt to the construction error of stake, and the adjustable program mark of node satisfies on-the-spot connection request when realizing on-the-spot the installation.
2, the field Welding workload is little, and is easy for installation, and speed is fast.
3, node is stressed safe and reliable.
Description of drawings
Accompanying drawing is a kind of structural representation that is used for the connected node regulated of blower foundation piling bar and conversion steel work of the present utility model.
Number in the figure:
1 is steel pipe pile, 2 short columns for blower foundation conversion steel work, and 3 is retaining collar, 4 is steel pipe pile interior lining panel and stiffener, and 5 is short column base plate and stiffener, and 6 is the level adjusting gap between short column 2 and the steel pipe pile 1, irritate high strength grout, 7 is the rest at steel pipe pile top.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to accompanying drawing, the utility model is a kind of blower foundation piling bar and connected node regulated of changing steel work of being used for, and the blower foundation piling bar can be a steel pipe pile 1, and steel pipe pile 1 is the ordinary steel pile tube, can be box section, round tube or polygon pipe; Steel pipe pile 1 also can be steel tube concrete pile.
Steel pipe pile 1 is connected with blower foundation conversion steel work by short column 2.Be provided with gap 6 in level and short transverse between short column 2 and the steel pipe pile 1, regulate, adapt to the site operation error of steel pipe pile 1 with the space three-dimensional that realizes connected node.The size in gap can be determined according to the regulated quantity that reality requires.
After blower foundation conversion steel work was in place, three-dimensional was adjusted to design attitude, and is fixing, pours into high strength grout in the space 6 between short column 2 and steel pipe pile 1, and this space is filled up, and realizes the location of conversion steel work, and connection is finished in final welding.
As shown in FIG., be provided with base plate and stiffener 5, in steel pipe pile 1, be provided with liner plate and stiffener 4, in order to strengthen its strength and stiffness in short column 2 bottoms.
The utility model has been realized the blower foundation piling bar and has been changed being connected of steel work, and its connected node can be regulated.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
