So-called wedge shape anchor (free end of prestress application device is clipped in described wedge shape anchor and is anchored in place by wedge) is often used as anchoring device.Yet these have the shortcoming of being slided.As a result, compare and be difficult to regulate the prestressing force in prestress application device, thereby described prestressing force is especially as a large amount of overstress of comparing that must first be applied in slip that compensation occurs subsequently.In addition, wedge shape anchor needs each prestress application device to have larger unnecessary length.This means each prestress application device must be after stressing operations manually or cut away by complicated instrument.This is very arduous and adventurous process also sometimes, and this process has hindered remaining constructions work in braced structures.
In this regard, must be clear that, this type of hundreds of prestress application devices is used in the structure as instantly discussed.Generally speaking, thereby high-caliber manual the intervention and very difficult automation of current common wedge anchor Technology Need.
Summary of the invention
Therefore, the object of this invention is to provide this related class turriform braced structures of beginning, described turriform braced structures allows independent prestressed concrete part accurately and reliably to fix each other, and makes the automated manufacturing degree of turriform braced structures can have lifting simultaneously.
According to the present invention, the turriform braced structures that this object proposes by claim 1 and the method for the manufacture of turriform braced structures proposing by claim 13 realize.In dependent claims, specifically described the particularly preferred embodiment of the present invention.
The present invention is based on when each independent prestressed concrete part is connected to each other or is fixed, in the region of end anchor device, eliminate the concept of sliding.For this reason, according to the present invention, the prestress application device of this class turriform braced structures provides at least at one end has form fit device, particularly screw thread, and described prestress application device is anchored in contiguous prestressed concrete part via at least one end anchor, described end anchor is via form fit device or be threaded io prestress application device.
This makes each prestressed concrete part not to be connected to each other in the situation that particularly sliding, and therefore in extremely accurate and reliable mode, has regulated power and the distortion occurring during fixing.In addition, this design with the prestress application device of form fit device, particularly screw thread allows each free-ended unnecessary length at least at this free end, to be reduced to minimum, because this free end can the mode with form fit be grasped by suitable pulling force equipment.Due to this short unnecessary length, each free end is without being cut off after fixing, and this has increased the safe coefficient of operation and operation to a great extent.
According to another considerable advantage of design of the present invention, be, can in the degree larger than prior art, make to fix contiguous prestressed concrete part automation.The known multiple intervention of wedge anchor Technology Need, and can almost by suitable automatic prestressing force machine, implement completely according to this class grappling of the present invention.If consider must time the very large At The Height of being everlasting complete the operation in turriform braced structures, the automaticity improving allows to realize further considerable advantage, such as particularly for site staff's improvement employment security.Especially, can utilize simple in structure thereby cheaply parts realize according to this class according to the present invention and connecting and grappling.
According to another embodiment of the present invention, end anchor is set as and can gets at from the chamber of turriform braced structures inside.This has not only simplified building course, and makes the end anchor of braced structures effectively resist weather activity, thereby allows to increase the durability of braced structures and reduce the requirement to component corrosion protection.
Although principle upper end anchor can be directly supported on the concrete of prestressed concrete part, another embodiment according to the present invention, each end anchor is set as via being preferably embedded in the support member in concrete and is supported in concrete.Result is, high local power is imported in concrete equably, and this has cut down the stress in concrete and has concentrated and additionally cut down the distortion producing due to creep and contraction.In addition, can reduce required lateral pull strengthening and/or gap strengthening.In addition, support member can help avoid in corresponding prestress application device eccentric.Can design support member according to various mode, wherein, as the shape of encircleing, be proved to be and there is special advantage.
Another exploitation form according to the present invention, also can be set as at least a portion of prestress application device via bonding mixture, to be anchored at alternatively and insert in passage.This has caused special Transmit evenly grappling and prestressing force.Meanwhile, protected prestress application device to avoid environment, the particularly impact of corrosion.In addition, can after bonding mixture solidifies, outward winding alternatively and reuse anchoring device, when this prestress application device in the high quantity of consideration and anchoring device, can not ignore.On the other hand, the use of unsticking prestress application device (also possible alternatively) provides the advantage of simplified support structure dismounting.
When bonding mixture is injected to insertion passage, tool is marginal, with bonding mixture, fills insertion passage completely, to reach grappling and the protective effect of expectation.In view of this, another embodiment according to the present invention, end anchor is set as has through hole (for example groove), and described through hole is used for making bonding mixture to discharge.By this way, can inject bonding mixture from inserting the lower end of passage, until the through hole that described bonding mixture inserts passage upper end through being located at of end anchor is discharged.Hold the through hole in anchor thereby there is dual-use function, that is, facilitated completely and filled on the one hand, the controlling mechanism of filling is completely provided on the other hand.
On the other hand, can have advantage within the scope of the present invention, between prestress application device and prestressed concrete part, specified point place does not deliberately provide bonding.In view of this, another embodiment according to the present invention, is set as in bonding between prestress application device and prestressed concrete part that at least the jointing place between contiguous each prestressed concrete part is weakened or destroyed.This allows obviously to increase the spread of each prestress application device length, so that can apply sizable prestressing force in the situation that the concrete of each prestressed concrete part is not produced to threat.In addition, also can make prestress distribution adapt to each concrete section by deliberately omitting bonding (" unsticking "), described cross section be for example in such region: in described region, the concrete section of prestressed concrete part is larger or less.
Another embodiment according to the present invention, prestressed concrete part also can be set as and comprise for inserting the insertion passage of the prestress application device of contiguous prestressed concrete part.Therefore the present invention is based on " external prestress ", but preferably for through each prestressed concrete part guiding prestress application device.This makes can have uniform prestress distribution when having the prestress application device of low quantity comparatively speaking.By this, particularly preferably be along the direction with inserting prestress application device opposite direction and increased the cross section of inserting passage.This has simplified significantly by prestress application device insertion passage.Can be for example by utilizing suitable tringle to manufacture insertion passage.Yet alternatively also can provide sheath etc., good bonding because wrinkling sheath has been particularly suitable for.
Prestressed concrete part can have any basic configuration in principle within the scope of the invention.Another embodiment according to the present invention, prestressed concrete part also can be designed to annular (being for example designed to Rotational Symmetry part, such as cylinder, circular cone or parabola body), and this has caused having bearer properties and the simple manufacturing process of special advantage.As selection, another embodiment according to the present invention, prestressed concrete part also can be designed to ring section shape.This has simplified the transportation of prestressed concrete part, and prestressed concrete part can be in place in traditional stress bed by casting on flat.This has not only facilitated manufacture process, and makes can there be smooth contact surface on the upside of prestressed concrete part subsequently and downside.
In addition, another embodiment according to the present invention, prestress application device is made as at least two-layer in each prestressed concrete part.This makes can use comparatively speaking thin prestress application device, and this has obviously facilitated conversely and prestress application device is screwed into contiguous prestressed concrete part and to the stretching of prestress application device and grappling.Another result is that prestressing force distributes especially uniformly in support member.The layer of prestress application device can be interpreted as by this to the layer that the periphery wall that refers to each prestressed concrete part extends in parallel.
In principle within the scope of the invention, whole turriform braced structures is roughly comprised of prestressed concrete part.Yet same, the present invention also makes to mix to build becomes possibility, and in described mixing is built, for example the lower area of turriform braced structures is comprised of prestressed concrete part, and the upper region of turriform braced structures is formed by one or more steel sections.In view of this, another embodiment according to the present invention, provide at least one prestressed concrete part to be connected to contiguous head tower sections, so that most elongated prestress application device is imported in contiguous head tower sections and under tensile stress, be anchored at there.Thereby, utilize identical basic catenation principle, and therefore can realize in principle above-mentioned advantage.Yet, the unsticking of prestress application device is particular importance for this connection, because be conventionally found in little extension while being connected with head tower sections or extend, can increase by the unsticking of being demarcated in corresponding prestressed concrete part, so that can apply high prestressing force in concrete situation not damaging.In addition, need to be than connecting the prestressing force that required prestressing force is higher between prestressed concrete part to the integrated process of head tower sections.
In order to make reliably these high connection power become possibility, another embodiment according to the present invention, the mode that extra anchoring device is set as with form fit is anchored in prestressed concrete part, is directed to contiguous head tower sections and under tensile stress, is anchored at there.Thereby prestress application device on the one hand and the combination of anchoring device have on the other hand been used, described prestress application device has guaranteed that prestressing force is applied to each prestressed concrete part simultaneously, and described anchoring device is only anchored in prestressed concrete part in the mode of form fit.This allows to realize the gradual change of being demarcated of prestressing force and anchorage force in reliable connection member.
Another embodiment according to the present invention, contiguous head tower sections is also set as and comprises concrete segment, particularly concrete ring, and elongated prestress application device and optional anchoring device are guided through described concrete segment.Due to this extra concrete segment, can reduce the surface pressing on joint, and increase the rigidity of head tower sections simultaneously.In addition, especially, when having concrete ring, the lateral strain that concrete ring is caused by prestressing force causes the excessive pressure on the concrete being surrounded by steel, and this makes to apply high load.In this respect, concrete segment particularly preferably is the steel that are connected to contiguous tower sections in the mode of form fit, thereby has produced and have the very firm of the minimum slip and connect reliably comprehensively.
Claim 13 defines a kind of according to the method for the manufacture of turriform braced structures of the present invention.Therefore as mentioned above, the method makes automation technolo and the low slip of height become possibility, makes to be reliably connected to become possibility between each prestressed concrete part or each tower sections.Particularly preferably be, prestressed concrete part is vertically poured into a mould in place, and preferably by self-compacting concrete, is made herein.
Yet vertically pouring concrete can produce the inhomogeneous problem of upside of prestressed concrete part, because due to outstanding prestress application device, smooth upside is difficulty or impossible.In view of this, another embodiment according to the present invention, prestressed concrete part has self-leveling mixture after being set as casting process on their upside.The surface that this has caused the accurate level of prestressed concrete part, allow described prestressed concrete part at stacked on top without process again reliably operation or smoothing measure in the situation that on building site.

The specific embodiment
Now in connection with accompanying drawing in detail preferred each embodiment of the present invention is described in detail.
Fig. 1 has schematically shown according to the partial sectional view of turriform braced structures 1 of the present invention.Turriform braced structures can be served the various objects in the scope of the invention, and for example also by the braced structures that acts on wind park.Turriform braced structures 1 is by a plurality of prestressed concrete parts 2,4 of stacked on top and they are fixed together and are built up, and wherein, each in prestressed concrete part 2,4 comprises the elongated prestress application device 10 of a plurality of pulling force cables or twisted wire form.As seen from Figure 1, upper to surpass part outstanding at the upside of part (in Fig. 1 on right side) for the prestress application device 10 of prestressed concrete part 2, and be imported into and in contiguous prestressed concrete part 4 and under tensile stress, be anchored at there.In this layout, each prestress application device whole or only a plurality of being anchored in contiguous prestressed concrete part 4.
Each prestress application device 10 has form fit device in its anchored end, in present embodiment, this form fit device is designed to screw thread, but also can for example be designed to as rib, and each prestress application device 10 is anchored in contiguous prestressed concrete part 4 via end anchor 12, holds anchor to be designed to pulling force nut described in present embodiment.This pulling force nut is screwed onto on the screw thread of prestress application device 10.Yet, also can use the end anchor being crushed on form fit device.
In the following example as completed the connection of prestressed concrete part 2 and 4 and fixing.First prestressed concrete part 2 is vertically located so that the vertical zone level upright and joint 32 of the free end of prestress application device 10 is directed.Utilize subsequently crane that contiguous prestressed concrete part 4 is placed on the top of prestressed concrete part 2, so that in the through hole that the prestress application device of prestressed concrete part 2 10 inserts in contiguous prestressed concrete part 4, until contiguous prestressed concrete part 4 finally leans against on prestressed concrete part 2 in the region of joint 32.In this case, the screw thread free end of prestress application device 10 is outstanding to a certain degree from the through hole of contiguous prestressed concrete part 4.Now hold anchor 12 to be screwed onto on prestress application device 10, and the free end of prestress application device 10 is grasped by the suitable pulling force equipment such as hydraulic press.The screw thread of prestress application device 10 makes it may only need outstanding minimum degree, thereby is grasped reliably by pulling force equipment.
Pulling force equipment is applied to prestress application device 10 by the tensile stress of scheduled volume subsequently.After reaching the tensile stress of scheduled volume, end anchor 12 or pulling force nut 12 are tightened up in abutting connection with support member 14, " freeze " by this pre-stressed state being caused by pulling force equipment.Pulling force and the end anchor 12 that now can discharge pulling force equipment have been guaranteed to keep pre-stressed state between prestressed concrete part 2 and 4 in zero-lash situation.
Although can complete this stressing operations by various discrete equipment, advantageously complete most of above-mentioned steps by automatic prestressing force and screwing equipment within the scope of the present invention.
Can get at from the chamber 1 ' (in the bottom of Fig. 1) of turriform braced structures 1 inside end anchor 12, wherein, turriform braced structures is for example designed to have the middle void tower of circle or any other cross sectional shape.
In addition, prestress application device 10 for example, is anchored in prestressed concrete part 4 in the region between joint 32 and end anchor 12 via bonding mixture (bonding mortar) alternatively.This bonding mixture for example can be injected in the corresponding chamber in prestressed concrete part 4 subsequently.End anchor 12 preferably has through hole (for example groove), and it is not shown specifically, thereby described through hole is used for making bonding mixture 16 to discharge conveniently to inject and guarantee, fills completely.Except even grappling is provided, this bonding mixture is also guaranteed reliable corrosion protection, yet also can adopt other optional or extra corrosion protection measures, such as fat liquoring, upper coating etc.In addition, thus further improve corrosion protection can be aptly to coating on end anchor 12.
As a comparison, in the region of indicating with " a ", between prestress application device 10 and prestressed concrete part 2, be bonded in contiguous jointing 30 places weakened or even destroyed (" unsticking ") in Fig. 1.This allows prestress application device to reach higher stretch value, thereby has avoided when prestress application device 10 is stretched concrete damage.
