Detailed description of the invention
Being described in detail embodiments of the invention now, its example represents in the accompanying drawings, and wherein, identical label represents identical parts all the time.It is described to explain the present invention to embodiment below with reference to the accompanying drawings.
Fig. 1 is the front view of the inner supporting structure illustrating concrete tower according to embodiments of the present invention；Fig. 2 is the top view of the inner supporting structure illustrating precast concrete tower according to embodiments of the present invention；Fig. 3 is the partial enlarged drawing of the top view of the inner supporting structure illustrating precast concrete tower according to embodiments of the present invention；Fig. 4 A and Fig. 4 B is the precast concrete tower internal structure profile along A-A subdivision, and wherein Fig. 4 A is bolt connecting mode, and Fig. 4 B is welding manner.
Tower frame for wind generating set 10 as shown in Figure 1 to Figure 3 is sequentially formed by fixedly connecting by more piece tower head and the tail, each joint tower has precast concrete, head and the tail can form a conical tower 10 after being sequentially connected with, and described conical tower 10 has internal conical surface and outer conical surface.Being provided with prestressing force lockset 30 on the madial wall (that is, internal conical surface) of tower, described prestressing force lockset 30 highlights from the madial wall of tower, and has the hole making prestressing force rope (or presstressed reinforcing steel) pass.As shown in Figures 2 and 3, described prestressing force lockset 30 is circumferentially spaced setting.In the vertical direction, when more piece tower is sequentially fixedly connected to form conical tower 10, it is positioned at the prestressing force lockset 30 generatrix direction alignment along the internal conical surface of tower of differing heights, make each prestressing force rope along inner side taper seat generatrix direction sequentially through each prestressing force lockset time be able to ensure that the same prestressing force rope same generatrix direction along tower, to balance prestress rope muscle shearing force in the horizontal direction, it is to avoid the movement in the horizontal direction of prestressing force rope.
In order to avoid inner supporting structure affects the installation of prestressing force lockset, inner supporting structure needs to avoid prestressing force lockset.Therefore, support beam 40 is arranged between adjacent prestressing force lockset 30, and the fixing connection arc beams 50 in the end of support beam 40.By arranging multilayer circle arc support beam 40 and arc beams 50 at the differing heights of tower, available arc beams 50 is as the supporting construction of the lift supporting construction of cat ladder guide rail, cable etc., thus avoids affecting the installation of prestressing force lockset.
As shown in figs 2-4, circle arc support beam 40 can be column, extends along radial direction from the madial wall of tower, i.e. its one end is fixedly connected on the madial wall of tower, and the other end is fixedly connected in arc beams 50, and circle arc support beam 40 points to the direction, the center of circle of tower.Arc beams 50 is fixedly mounted on the end of adjacent multiple circle arc support beams 40 of same level height.As example, each arc beams 50 can be supported by three circle arc support beams 40, and three circle arc support beams 40 can be connected to middle part and the two ends of arc beams 50.Arc beams 50 can be circular arc, and more specifically, arc beams 50 can be one section of arc of circle.The profile diameter of arc beams 50 can adjust along with the change in location of short transverse, it is preferable that can make the arc beams 50 at differing heights can be along the same generatrix direction consistency from top to bottom of pylon taper seat by adjusting the length of support beam 40.Such as, the center line that can make the multiple arc beams 50 at differing heights is positioned on the same generatrix direction of taper pylon 10.It addition, multiple arc beams can be made to be positioned on the same conical surface.The supporting construction that the arc beams being constructed such that is formed enables to lift and lifts along straight line path.
Although additionally, illustrate in figs. 2 and 3 for one section of arc beams, but, the invention is not restricted to this, as it is shown in figure 1, can as required or installation situation arranges multi-section circular arc beam at sustained height.
In order to ensure the support strength of arc beams, the two adjacent support beams and the angle α in direction, the center of circle, β connected with arc beams, such as, no more than 40 ° can be adjusted.Angle between the support beam that each two is adjacent can be identical, it is also possible to different, can adjust accordingly according to the position of prestressing force lockset, i.e. multiple circle arc support beams can at equal intervals or unequal interval ground is arranged.
As shown in Figure 4 A and 4 B shown in FIG., can with bolts or and welding connecting mode between described circle arc support beam 40 and tower madial wall.As shown in Figure 4 A, at the pre-buried connecting elements of tower inwall, one end of circle arc support beam can be fabricated to adpting flange when precast concrete tower, then by bolt, circle arc support beam is fixedly installed on tower inwall.As shown in Figure 4 B, it is also possible to circle arc support beam is welded on the built-in fitting on tower inwall.It addition, the connection between circle arc support beam 40 and arc beams 50, it is possible to the mode such as with bolts or welding.But, the present invention does not limits to and this.
According to technical scheme, although the inwall in tower is provided with prestressing force lockset, but, by arranging support beam between prestressing force lockset, and fixing connection arc beams in support beam, prestressing force lockset can be avoided to arrange supporting construction.Therefore, by arranging support beam and arc beams at the differing heights of pylon, make the arc beams consistency from top to bottom at differing heights and be positioned on the same conical surface, inner supporting structure can be formed at a certain segmental arc of tower, this supporting construction can be used to support the cat ladder 70 of lift 80, cable cleat 60 etc., thus the problem solving inner supporting structure.
Owing to the length of support beam and the profile diameter of arc beams can adjust along with the change in location of short transverse, therefore, the version of arc beams can solve lift well along tower wall moving up and down in the height direction, meets the special tectonic requirement within tower.
Arc beams and support beam structure are simple and reliable, it is possible to make the cost of precast concrete tower mould reduce, make xoncrete structure cost reduce.By utilizing support beam and arc beams to form the inner supporting structure of tower, it is possible to ensure the normal work of prestressing force lockset, and processing cost can be reduced, decrease field erected difficulty of construction, mounting process is had certain optimization function.And the normal work of prestressing force lockset 30 can be ensured.
Although some embodiments of the present invention are had been shown and described, but, it should be appreciated by those skilled in the art, without departing from the principles and spirit of the present invention, can make change in these embodiments, the scope of the present invention is limited by claim and equivalent thereof.
