Abstract
A kind of prestressing force assembly type blower foundation disclosed by the invention, including sole plate, the base is made up of prefabricated component, prefabricated component includes central part and extremity piece, there is the deformed bar hole of insertion on the joint face of central part and extremity piece, it is attached by deformed bar, each face of central part surrounding is provided with groove, and extremity piece junction side is provided with tongue；Base is attached with top blower fan tower barrel structure by prestressed reinforced concrete circular rod, and central part top is provided with concrete secondary grout hole, is attached with circular rod by concrete secondary grouting.The prestressing force assembly type blower foundation provided is provided, precast block is carried out to concrete first, prefabricated component different during blower foundation is installed and carries out prestressed stretch-draw connection, base is attached with blower fan tower barrel structure by transition structure.Compared with cast in place reinforced bar concrete foundation, the present invention have the advantages that bending resistance is strong, the set-up time is short, resource without waste, will not be formed dismounting rubbish.
Description
Technical field
The present invention relates to blower fan field, more particularly to a kind of prestressing force assembly type blower foundation.
Background technology
Wind turbines basis is the concrete structure for fixing unit, and it will not only bear the weight of unit and tower,
And to resist the maximum tipping load of unit, it is ensured that safe operation of the unit under various load.The conduct of Wind turbines basis
The safe and reliable operation of the important component of Construction of Wind Power, not only relation wind field, have an effect on the investment of wind field.Traditional
Wind turbines basis generally use bearing platform type basis, it is one section of tower of embedment in bearing platform type basis（Foundation ring）, units' installation
When, tower drum flange is connected with basic ring flange.Scene is needed to carry out one-piece casting during foundation construction, quantities is big, construction quality
It is not easy to ensure.
The content of the invention
A kind of prestressing force assembly type blower foundation is provided it is an object of the invention to overcome the deficiencies in the prior art.
The purpose of the present invention is achieved through the following technical solutions：
A kind of prestressing force assembly type blower foundation, including sole plate, the base are made up of prefabricated component, and prefabricated component includes
There is the deformed bar hole of insertion on the joint face of central part and extremity piece, central part and extremity piece, connected by deformed bar
Connect, each face of central part surrounding is provided with groove, and extremity piece junction side is provided with tongue；Base passes through with top blower fan tower barrel structure
Prestressed reinforced concrete circular rod is attached, and central part top is provided with concrete secondary grout hole, is passed through with circular rod mixed
Native back-grouting is coagulated to be attached.
The prefabricated component also includes balancing weight, and balancing weight joint face is provided with tongue.
The circular rod is attached with upper column barrel structure by flange.
Prestressing force assembly type blower foundation provided by the invention, precast block is carried out to concrete first, blower fan base is installed
Different prefabricated components carries out prestressed stretch-draw connection during plinth, and base is attached with blower fan tower barrel structure by transition structure.With
Cast in place reinforced bar concrete foundation is compared, the present invention have bending resistance is strong, the set-up time is short, resource without waste, dismounting rubbish will not be formed
The advantages that rubbish, the present invention are applied in blower foundation, still belonged to the first time both at home and abroad.

Embodiment
A kind of prestressing force assembly type blower foundation provided by the invention, as shown in Figure 1, including sole plate, the bottom
Seat is made up of prefabricated component, and prefabricated component includes central part 1, extremity piece 2 and balancing weight 3, as shown in Figure 3 and Figure 4, central part 1 and extremity piece 2
Joint face on have the reserved deformed bar hole 8 of insertion, use high-strength prestressed flexible connection by inserting deformed bar 7
Technology carries out prestressed stretch-draw connection, as shown in Fig. 2 each face of the surrounding of central part 1 is provided with groove 5, as shown in figure 3, extremity piece 2 connects
Junction is provided with tongue 6；The joint face of balancing weight 3 is provided with tongue 6, and groove 5 and tongue 6 mutually agree with the shearing resistance caused between each prefabricated component
Ability greatly increases.Base is attached with top blower fan tower barrel structure by the concrete circular rod 4 of deformed bar 7, annular
Deformed bar 7 is set in bar 4 can strengthen the anti-shear ability of circular rod 4, and circular rod 4 is as shown in figure 5, the top of central part 1 is set
There is concrete secondary grout hole 9, be attached with circular rod 4 by concrete secondary grouting；Circular rod 4 and upper column barrel structure
It is attached by flange.
Balancing weight 3 plays a part of to increase quality, can selectively use according to the actual requirements；Prestressing force blower foundation of the present invention
Suitable for land and shallow water area.
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
