Below with reference to the accompanying drawings the formwork for placing of tower and the casting method of tower in the utility model embodiment are described.

Wind-power electricity generation can be used for according to the formwork for placing of the tower of the utility model embodiment firstly the need of explanation Tower pouring construction, can be used for thermal power generation tower construction, can be also used for chemical field application tower building Construction, be not restricted here.Hereafter only by formwork for placing for being illustrated for wind power tower tube construction.

Wherein, tower includes the multiple tower segments being sequentially connected from bottom to top, and at least one tower segments are by concreting It is solidified in formwork for placing, formwork for placing does not remove after the completion of tower is built to constitute a part for tower structure.Root There can be different structures according to the formwork for placing of the utility model embodiment, detailed description is different respectively below with reference to the accompanying drawings The structure type of formwork for placing under structure.

Below with reference to Fig. 1-Fig. 3 descriptions according to the structure of the formwork for placing of the utility model first kind embodiment.

Formwork for placing includes the multiple template unit 10 being sequentially connected end to end in turn in circumferential direction, i.e., for formwork for placing and Speech has two or more modular units 10 in circumferential direction, and wherein modular unit 10 includes interior matrix 1 and external mold Piece 2.

Interior matrix 1 is located on the madial wall of tower segments, and interior matrix 1 is corrugated sheet.Outer matrix 2 is located in the outer of tower segments On side wall, outer matrix 2 is corrugated sheet.Here as shown in figure 3, corrugated sheet refers to that the shape on a certain section of plank is wave Shape.Since interior matrix 1 and outer matrix 2 use corrugated sheet, plank, which is equivalent to, have passed through multiple bending, and the rigidity of plank obtains greatly It is big to be promoted, to which anti-pressure ability, the impact resistance of interior matrix 1 and outer matrix 2 can be all greatly improved.

In the utility model embodiment, since formwork for placing does not remove after the completion of tower is built, i.e., tower has been built Cheng Hou, interior matrix 1 constitute the endothelium of tower, and outer matrix 2 constitutes the crust of tower, and tower builds up rear overall aesthetic degree can be significantly It improves.And since during being conserved after each tower segments pour, formwork for placing is also not remove, and can keep coagulation The moisture of soil improves maintenance quality and reduces curing time, so as to substantially reduce construction cost.

On the one hand inside and outside wall using corrugated sheet as tower utilizes the higher rigidity of corrugated sheet, can resist concrete and exist The internal stress and external impact force generated when solidification, to avoid formwork for placing deformation, displacement, and then protect tower segments at Type quality.

On the other hand, since formwork for placing is after the completion of tower is built, interior matrix 1 and outer matrix 2 just become tower segments The rigidity of structure of internal and external peripheral wall, the internal and external peripheral wall of tower segments waveform increases, and tower overall stiffness is promoted, the longevity after tower comes into operation Life also can be longer.

According to the formwork for placing of the utility model embodiment, due to each modular unit 10 by using corrugated sheet as tower The inner and outer wall of cylinder section reduces arrangement of reinforcement so as to improve the inner wall strength and outer wall intensity of tower segments, simplifies construction step Suddenly.
