Description
Technical field
This utility model relates to a kind of offshore wind farm unit high-rise pile cap formula foundation construction facility field, particularly to one
Prestressed concrete back cover cushion cap template.
Background technology
At present, in China's Oversea wind power generation engineering, high-rise pile cap formula basis be Wind turbines main foundation pattern it
One.High-Rise Pile Cap Foundation needs marine Casting in-place Mass Concrete, therefore requires higher to cushion cap template.Compare tradition cap mold
Plate construction technology, prestressed concrete back cover cushion cap template is owing to decreasing working procedure, and operation on the sea amount is little, construction period
The features such as relatively short, cost is low, quality easily guarantee can be widely applied to the High-Rise Pile Cap Foundation of Oversea wind power generation engineering and execute
In work.
Wind turbines High-Rise Pile Cap Foundation structure due between pile foundation span relatively big, and cushion cap volume of concrete is big, makes bed die
Moment of flexure suffered by plate center position is the biggest.The steel bed die that the base plate employing shaped steel of conventional steel casing cushion cap template is strengthened, but steel
Bed die intensity still is not enough to support the deadweight during cushion cap concreting of top, need to after model sheetinstallat first marine cast-in-place about 1m
The bottom concrete of thickness, thus support the deadweight of superstructure concrete.Marine cast-in-place bottom concrete causes working procedure
Too much, long construction period, construction cost is too high.
Therefore, how reasonable arrangement working procedure, reduce Jobs on the sea amount and the cushion cap end template of sufficient intensity is set,
The deadweight supporting top cast-in-place structural concrete is an important step in bearing platform construction.
Utility model content
The purpose of this utility model is aiming at existing cushion cap template and there is working procedure too much, long construction period, construction
The shortcoming of high cost, it is provided that a kind of prestressed concrete back cover cushion cap template.
The technical solution of the utility model is: a kind of offshore wind farm unit high-rise pile cap formula foundation construction template, template is
The circular frame of steel-prestressed reinforced concrete combination, including prestressed concrete back cover, side template and support type girder steel；
Deformed bar, and the reserved hole corresponding with steel-pipe pile it is evenly arranged with in prestressed concrete back cover；
Side template is by the barb type round platform nut being embedded in prestressed concrete back cover and prestressed concrete back cover
Form a fixed connection；
Support type girder steel divides upper and lower two parts, and top half is " well " character form structure, is connected by pin with side template；
The latter half is " door " character form structure, is embedded in prestressed concrete back cover, erects on steel-pipe pile 1 top during installation；Up and down
Two parts are connected by vertical girder steel.
Specifically optimize as this utility model scheme, prestressed concrete back cover generally circular in shape.
Specifically optimize as this utility model scheme, side template be shaped as arc or fan-shaped steel form, quantity is 4
Or 8.
This utility model compared with prior art, has the advantage that as follows:
(1) land fabrication bottom concrete, decreases Jobs on the sea amount, and efficiency of construction is higher, and land fabrication quality is easy
Ensure；
(2) prestressing force bottom concrete intensity is higher, can bear bigger construction time load, and safety coefficient is greatly improved；
(3) bottom concrete directly serves as end template, saves the rolled steel dosage of original end template；
(4) working procedure is more reasonable, and construction period shortens, and ship machine equipment demand is little, greatly reduces construction cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments herein is described in detail, but the application can be defined by the claims
Implement with the multitude of different ways covered.The accompanying drawing of the part constituting the application is used for providing the further reason to the application
Solving, the schematic description and description of the application is used for explaining the application, is not intended that the improper restriction to the application.
A kind of offshore wind farm unit high-rise pile cap formula foundation construction template, template is steel-prestressed reinforced concrete combination
Circular frame, including prestressed concrete back cover 2, side template 3 and support type girder steel 4；In prestressed concrete back cover 2 uniformly
It is provided with deformed bar, and the reserved hole corresponding with steel-pipe pile 1；Side template 3 is by being embedded in prestressed concrete grave
Barb type round platform nut at the end 2 forms a fixed connection with prestressed concrete back cover 2；Upper and lower two of 4 points of support type girder steel
Point, top half is " well " character form structure, is connected by pin with side template 3；The latter half is " door " character form structure, is embedded in
In prestressed concrete back cover 2, erect on steel-pipe pile 1 top during installation；Two parts are connected by vertical girder steel up and down.
Specifically optimize as this utility model scheme, prestressed concrete back cover 2 generally circular in shape.
Specifically optimize as this utility model scheme, side template 3 be shaped as arc or fan-shaped steel form, quantity is 4
