The specific embodiment
Below in conjunction with accompanying drawing the concrete pylon that the utility model embodiment provides is described in detail.
As shown in Figure 1, be the specific embodiment of the utility model embodiment.The pylon of concrete described in the present embodiment comprises tower foundation 1; The top of said tower foundation 1 is provided with pylon body 2; Said pylon body 2 is connected to form along short transverse by two above stretch-draw sections 20 successively; Said stretch-draw section 20 is connected to form along short transverse by two above prefabricated units 200 successively, is provided with prestressed reinforcement 3 in the said stretch-draw section 20.
The concrete pylon that the utility model embodiment provides comprises tower foundation 1, and the top of said tower foundation 1 is provided with pylon body 2; Said pylon body 2 is connected to form along short transverse by two above stretch-draw sections 20 successively, and said stretch-draw section 20 is connected to form along short transverse by two above prefabricated units 200 successively, is provided with prestressed reinforcement 3 in the said stretch-draw section 20; Its beneficial effect that brings is; Because stretch-draw section 20 is connected to form along short transverse by two above prefabricated units 200 successively, so the height of the whole relatively pylon body 2 of the height of stretch-draw section 20 is lower, the constructor can carry out stretch-draw to each stretch-draw section 20 interior prestressed reinforcement 3 earlier on the ground like this; And then make each stretch-draw section 20 form a firm integral body; With loop wheel machine each stretch-draw section 20 is lifted along short transverse successively then, treat rigging out after, adjacent stretch-draw section 20 is fixedly connected; Further form a firm concrete towers support body 2; Because the concrete towers support body 2 after connecting does not need to carry out stretch-draw again, therefore not only avoided high-altitude stretch-draw operation, but also made construction convenient.
As shown in Figure 2; The top of said stretch-draw section 20 and bottom are equipped with flange 21 and 22; Like this loop wheel machine with each said stretch-draw section 20 after short transverse rigging out successively; Can adjacent two said stretch-draw sections 20 be fixedly connected with 22 through said flange 21, make pylon body 2 form a firm integral body.In addition, flange 21 and 22 thickness should be not less than 50mm.
And wherein need to prove; Because each said stretch-draw section 20 is formed by two above prefabricated units 200; Therefore compare with said prefabricated units 200 of each lifting, lift the lifting number of times that a said stretch-draw section 20 can reduce loop wheel machine at every turn, thereby reduce the cost of lifting.In addition; Owing to can lift two the above prefabricated units 200 on the ground earlier to form stretch-draw section 20; Therefore the hoisting height of each said prefabricated unit is lower; With needs said prefabricated units 200 are lifted to the pylon body and to compare, can select the less loop wheel machine of elevating capacity for use, effectively reduce the cost of lifting.
Be provided with said prestressed reinforcement 3 in the section 20 of stretch-draw described in this practical embodiment between the flange 21 and 22 at two ends; And said prestressed reinforcement 3 is arranged along the internal circumferential of said stretch-draw section 20; Like this at prefabricated units 200 when short transverse connects successively; Prestressed reinforcement 3 can not pass the inside of prefabricated units 200, but directly extends to the flange 21 on stretch-draw section 20 tops from the flange 22 of stretch-draw section 20 bottoms, is convenient to the connection between the prefabricated units 200; It can also be seen that in addition prestressed reinforcement 3 is arranged in the hollow parts of stretch-draw section 20, so prestressed reinforcement of tensioning 3 methods also can be called external stretching method.
Can know that by Fig. 2 the two ends of said prestressed reinforcement 3 are fixed on the flange 21 and 22 inside at said stretch-draw section 20 two ends, for example can the two ends of prestressed reinforcement 3 be anchored at flange 21 and 22 inside, and not stretch out the end face of flange 21 or 22.If be like this because prestressed reinforcement 3 stretches out the end face of flange 21 and 22; Then when lifting stretch-draw section 20; When being connected, the stretch-draw section 20 stretch-draw section 20 adjacent with its lower end interfere; And then cause adjacent stretch-draw section 20 normally to connect, and therefore the two ends of prestressed reinforcement 3 are fixed on the flange 21 and 22 inside at stretch-draw section 20 two ends, can avoid adjacent stretch-draw section 20 to take place to connect and interfere.
From Fig. 1, find out; The bottom of the prestressed reinforcement 3 in the said stretch-draw section 20 of bottommost is stretched out the end face of said flange 22 and is fixed in the said tower foundation 1, is provided with the fixing hole (not marking among the figure) that holds said prestressed reinforcement 3 bottoms in the said tower foundation 1.The stretch-draw section 20 of bottommost is located by connecting on the tower foundation 1, guarantees the steadiness of the stretch-draw section 20 of bottommost, thereby can guarantee the steadiness of concrete towers support body 2 on tower foundation 1 at tower foundation 1.
Can know that from Fig. 2 the flange 21 on said stretch-draw section 20 tops is structure as a whole with the prefabricated units 200 at said stretch-draw section 20 tops; The flange 22 of said stretch-draw section 20 bottoms is structure as a whole with the prefabricated units 200 of said stretch-draw section 20 bottoms; And the member of this integrative-structure can be the concrete component of making in advance in factory; Avoid independent making flange 21 and 22, thereby can shorten the production cycle.
One end of prefabricated units described in this practical embodiment 200 is provided with spacer bars 201, the other end is provided with the locating hole 201 that holds said spacer bars 201.As depicted in figs. 1 and 2; When adjacent two prefabricated units 200 connect; The spacer bars 201 of upper end prefabricated units 200 stretches in the locating hole 201 of lower end prefabricated units 200; Guarantee the connective stability of two adjacent prefabricated units 200, so just not only can improve the stability of stretch-draw section 20, can also further improve the stability of concrete towers support body 2.
In addition, the quantity of prestressed reinforcement 3 described in the utility model embodiment is more than two, and the quantity of the prestressed reinforcement 3 in each stretch-draw section 20 flexible arrangement according to actual needs, thereby has reduced the waste of prestressed reinforcement 3.
It is emphasized that the suitable altitude range of concrete towers support body 2 is 50 meters-200 meters among the utility model embodiment, and this concrete towers support body 2 durability of structures are better than the durability of head tower barrel structure.
In sum, the preparation method of concrete towers support body 2 under here can brief account:
(1) earlier two above prefabricated units 200 is connected to form stretch-draw section 20 successively along short transverse, then the prestressed reinforcements 3 in the stretch-draw section 20 are carried out external stretch-draw and the two ends of prestressed reinforcement 3 are anchored in flange 21 and 22;
(2) make several stretch-draw sections 20 according to method (1);
The stretch-draw section 20 that (3) will be positioned at pylon body 2 bottommosts earlier is lifted on the tower foundation 1, and this stretch-draw section 20 is fixedly connected with tower foundation 1;
(4) next stretch-draw section 20 is lifted the upper end of bottom stretch-draw section 20, so more remaining stretch-draw section 20 is lifted along short transverse successively, treat rigging out after, form a concrete towers support body 2;
(5) adjacent two stretch-draw sections are fixedly connected, and then form a firm concrete towers support body 2.
The above; Be merely the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; Can expect easily changing or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by said protection domain with claim.
