Embodiment
Now embodiment of the present utility model is described in detail, in the accompanying drawings, wherein, identical label represents identical parts to its example shown all the time.Below with reference to the accompanying drawings embodiment is described to explain the utility model.
Fig. 1 is the plan view illustrating according to the inner supporting structure of the utility model embodiment's concrete pylon; Fig. 2 is the plan view illustrating according to the inner supporting structure of the utility model embodiment's precast concrete tower cylinder; Fig. 3 is the partial enlarged drawing illustrating according to the plan view of the inner supporting structure of the utility model embodiment's precast concrete tower cylinder; Fig. 4 A and Fig. 4 B be precast concrete tower cylinder internal structure along the sectional drawing of A-A subdivision, wherein Fig. 4 A is bolt connecting mode, Fig. 4 B is welding manner.
Tower frame for wind generating set 10 is as shown in Figure 1 to Figure 3 formed by fixedly connecting in turn by more piece tower cylinder head and the tail, each saves tower cylinder and has precast concrete, head and the tail can form a conical tower 10 after connecting in turn, and described conical tower 10 has internal conical surface and outer conical surface.On the madial wall (that is, internal conical surface) of tower cylinder, be provided with prestressing force lockset 30, described prestressing force lockset 30 highlights from the madial wall of tower cylinder, and has the hole that prestressing force rope (or prestressed tendon) is passed.As shown in Figures 2 and 3, described prestressing force lockset 30 arranges along circumferencial direction interval.In the vertical direction, when more piece tower cylinder is fixedly connected to form conical tower 10 in turn, be positioned at the prestressing force lockset 30 of different heights along the generatrix direction alignment of the internal conical surface of tower cylinder, make along the generatrix direction of inner side conical surface, can guarantee that same prestressing force rope along the same generatrix direction of tower cylinder during in turn through each prestressing force lockset at each prestressing force rope, with balance prestress rope muscle shearing force in the horizontal direction, avoid the movement in the horizontal direction of prestressing force rope.
For fear of inner supporting structure, affect the installation of prestressing force lockset, inner supporting structure need to be avoided prestressing force lockset.Therefore, support beam 40 is arranged between adjacent prestressing force lockset 30, and is fixedly connected with arc beams 50 in the end of support beam 40.By the different heights place at tower cylinder, multilayer circle arc support beam 40 and arc beams 50 are set, can utilize arc beams 50 as the supporting structure of the supporting structure of cat ladder guide rail, cable etc. for lift, thereby avoid affecting the installation of prestressing force lockset.
As shown in Fig. 2-Fig. 4, circle arc support beam 40 can be column, from the madial wall of tower cylinder, along radial direction, extends, that is, its one end is fixedly connected on the madial wall of tower cylinder, and the other end is fixedly connected in arc beams 50, and circle arc support beam 40 points to the center of circle direction of tower cylinder.Arc beams 50 is fixedly mounted on the end of adjacent a plurality of 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 particularly, arc beams 50 can be one section of arc of circle.The profile diameter of arc beams 50 can be adjusted along with the change in location of short transverse, preferably, can be by adjusting the length of support beam 40, make the arc beams 50 at different heights place can be along the same generatrix direction consistency from top to bottom of pylon conical surface.For example, can make the center line of a plurality of arc beams 50 at different heights place be positioned on the same generatrix direction of taper pylon 10.In addition, can make a plurality of arc beams be positioned on the same conical surface.The supporting structure that the arc beams of structure forms like this can make lift along straight line path lifting.
In addition, although shown in Fig. 2 and Fig. 3, be one section of arc beams,, the utility model is not limited to this, as shown in Figure 1, can be as required or installation situation at sustained height place, multi-section circular arc beam is set.
For adjacent two support beams of guaranteeing the support strength of arc beams, can adjust to be connected with arc beams and angle α, the β of center of circle direction, for example, be not more than 40 °.Angle between every two adjacent support beams can be identical, also can be different, can adjust accordingly according to the position of prestressing force lockset, that is, a plurality of circle arc support beams can be uniformly-spaced or unequal interval ground arrange.
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 cylinder madial wall.As shown in Figure 4 A, can when precast concrete tower cylinder, at the pre-buried connector element of tower cylinder inwall, one end of circle arc support beam be made into adpting flange, then by bolt, circle arc support beam be fixedly installed on tower cylinder inwall.As shown in Figure 4 B, also circle arc support beam can be welded on the embedded part on tower cylinder inwall.In addition, being connected between circle arc support beam 40 and arc beams 50, also can be with bolts or the mode such as welding.But the utility model does not limit to therewith.
According to the technical solution of the utility model, although at the inwall of tower cylinder, be provided with prestressing force lockset,, by between prestressing force lockset, support beam being set, and be fixedly connected with arc beams on support beam, can avoid prestressing force lockset supporting structure is set.Therefore, by the different heights place at pylon, support beam and arc beams are set, make the arc beams consistency from top to bottom at different heights place and be positioned on the same conical surface, can form inner supporting structure at a certain segmental arc place of tower cylinder, this supporting structure can be used for the cat ladder 70, cable cleat 60 etc. of supporting elevation machine 80, thereby solves the problem of inner supporting structure.
Because the length of support beam and the profile diameter of arc beams can be adjusted along with the change in location of short transverse, therefore, the structural type of arc beams can solve well lift along tower barrel moving up and down in short transverse, meet the special tectonic requirement of tower cylinder inside.
Arc beams and support beam structure are simple and reliable, can make precast concrete tower cylinder mould cost, make concrete structure cost.By utilizing support beam and arc beams to form the inner supporting structure of tower cylinder, can guarantee the normal work of prestressing force lockset, and can cut down finished cost, reduced field erected difficulty of construction, mounting process is had to certain optimization function.And can guarantee the normal work of prestressing force lockset 30.
Although represented and described embodiments more of the present utility model, but, it should be appreciated by those skilled in the art, in the situation that not departing from principle of the present utility model and spirit, can make in these embodiments change, scope of the present utility model is limited by claim and equivalent thereof.
