Problems solved by technology
This results in a very large mold cost in the early stage, which restricts the popularization and use of concrete prefabricated tower tubes
[0003] The polygonal tower can solve the shortcomings of many types of molds, high upfront costs, and difficult transportation to a certain extent, but there are still shortcomings such as many types of ring molds and difficulty in on-site assembly.
At present, this problem cannot be solved in the field of making and splicing tower tube rings in the prior art

Embodiment
[0043] Please see attached Figure 5 And attached figure 1, the angle of the obtuse corner structure of the inner template 4 and the outer template 5 of the adjustable mold is 135°, the first end mold 6 is connected with the end of the inner template 4 and the outer template 5 close to the obtuse corner structure, according to the size of the cylinder section, in The position of the second end form 7 is adjusted between the inner formwork 4 and the outer formwork 5, so that the length of the length-adjustable section 1 can be adjusted through the movement of the second end form 7, while the length and obtuse angle of the fixed corner section 2 of the prefabricated component The angle of the corner structure remains the same.
[0044] Please see attached figure 2 to attach Figure 4 , the embedded sleeves 31 are respectively embedded at both ends of the inner wall of the prefabricated component, and the movable bracket positioning pin 34 is matched and connected with the em...

The invention discloses a polygonal tower concrete precast component with fixed corners and an adjustable mold. The precast component comprises a length adjustable section (1) and a fixed corner section (2), wherein the length adjustable section and the fixed corner section are connected into the precast component with an integrated structure, an obtuse corner structure is formed between the length adjustable section and the fixed corner section of the precast component, and a plurality of precast components are spliced into a tower section through connecting assemblies (3). The adjustable mold comprises an inner mold plate (4), an outer mold plate (5), a first end mold (6) and a second end mold (7), wherein the inner mold plate is connected with the outer mold plate through the first endmold, the second end mold is arranged between the inner mold plate and the outer mold plate and moves along the inner mold plate and the outer mold plate to form the adjustable mold, one side of the inner mold plate and one side of the outer mold plate are bent to form obtuse corner structures, and the corner angle of the adjustable mold is equivalent to that of the precast component. According tothe polygonal tower concrete precast component, the manufacturing cost of the component mold can be reduced, and the component manufacturing efficiency, assembling precision and assembling efficiencyare improved.
Description
technical field [0001] The invention relates to a prefabricated part structure of a wind power tower tube and a mold thereof, in particular to a polygonal tower tube concrete prefabricated component with fixed corners and an adjustable mold thereof. Background technique [0002] Most of the wind power prefabricated concrete towers in the prior art are cylindrical, and the whole is frustoconical. Because there is a variable diameter in the height direction, the molds for each section are different, and different ring molds need to be made. Therefore, for a prefabricated concrete tower tube tens of meters high, about 20 ring molds have to be made. This has just caused the mold cost in the early stage to be very large, which has restricted the popularization and use of concrete prefabricated tower tubes. [0003] The polygonal tower can solve the shortcomings of many types of molds, high upfront costs, and difficult transportation to a certain extent, but there are still shor...
