Description
The present invention relates to a kind of device and a kind of corresponding method according to claim 10 that is used for strengthening bearing structure according to claim 1.
Usually such problem can occur when the bearing structure of the existing structure of trimming, promptly bearing structure should adapt to the new condition of loading bigger than former load.In order under this condition of loading, not exclusively to replace bearing structure, seek the method and apparatus of strengthening existing bearing structure.These bearing structures can be bridge, the traditional wall by brick one-tenth, reinforced concrete wall, steel concrete supporting body (beam), wooden supporting body (beam), plastics supporting body (beam) or steel supporting body (beam).
All the time, utilize the steel plate that afterwards adds to strengthen this bearing structure.Steel plate, promptly banded steel plate or steel disc are bonded on one or two face of bearing structure, preferably are bonded on the one side of bearing structure tension.The advantage of this method is, can implement relatively apace, however very high to the bonding requirement, that is, need prepare parts and bonding surface.In order to obtain desirable effect, the implementation process of bonding must be carried out under the condition that precisely limits.In the time of will strengthening the bearing structure of open-air state, bridge bearing body for example, the problem that makes in this way to be brought can appear at the corrosion zone especially.Consider weight and manufacturing situation that this steel disc is relatively large, maximal use length is restricted.Owing to the space, if the steel disc of rigidity can not be admitted in the corresponding space, can steel disc be encased in the closed space can be a problem simultaneously.In addition, steel disc must " from the top " (ü ber Kopf) be pressed on the bearing structure that need be reinforced when adding, and hardens fully until cementing agent, and this also brings very big cost simultaneously.
Recently also carbon element sheet material (CFK sheet material) is bonded on the side of bearing structure tension, thus by improving carrying drag and ductility in the load-carrying properties of having improved this structure afterwards.The application of this carbon element sheet material has simple and inexpensive advantage, and under the much smaller situation of weight, it has the intensity higher than steel disc, and is easy to lay.Corrosion resistance has also improved simultaneously, thereby this method also is fit to be used for strengthening open-air bearing structure.Be a problem especially but the end of carbon element sheet material is fixing.Exactly the danger that the carbon element sheet material comes off in this zone is very big, and the power transmission from carbon element sheet material end to bearing structure also is a problem.A kind of known solution is that insert wherein the end of CFK sheet material with the hole of slow rake angle extension or the recess of wedge shape to be provided with one on supporting body, necessary, by means of clip, winding or flat board or the like the CFK sheet material is pressed on the supporting body.This has just improved slip-off preventing performance and the power transmission from bearing structure to the CFK sheet material.
Common such CFK sheet material does not carry out pretension, that is, loosely be bonded on the supporting body.Thereby this major part is strengthened potentiality and is not fully utilized, because have only above after the basic load, promptly surpasses after the load of self useful load, and the CFK sheet material just begins carrying.In order to make full use of the CFK sheet material better, just produced such idea, that is, it is bonded on the supporting body in advance tightly.A relevant known method is, the short steel plate of bonding on the two sides of CFK sheet material end, steel plate is tightened up in the opposite direction, thus the CFK sheet material by pretension, then this structure by pretension is glued on the supporting body to be strengthened.After the cementing agent drying, utilize flat board, winding etc. in the end of CFK sheet material they to be pressed on the supporting body, the end that then will be provided with steel plate disconnects.But this method is expensive, and is not can both use in all application scenarios.The fixed form of above-described sheet material end is only limited to pretension at the construction field (site).
According to the known a kind of load-carrying unit of the EP1007809 reinforcement of concrete supporting body for example, this reinforcement has used the CFK sheet material, wherein the CFK sheet material is separated in the end, and is angle ground each other by boning, wedge or being fixed in the holddown groove of blocking element by the friction ways of connecting.Blocking element is fixed on the tension side of load-carrying unit by bonding, wedging or friction ways of connecting, perhaps blocking element is imbedded in the corresponding grooves of load-carrying unit under being with or without the situation of pretension.
The advantage of this solution is that the CFK sheet material has fixedly been realized bigger end bed knife with short and small, compact end.In addition, can under the situation of not using cementing agent, realize power transmission (friction connects).
The shortcoming of this method is that the CFK sheet material must carry out preliminary treatment or cutting to length in factory in the factory.And the CFK sheet material is cut apart is a thorny process, requires fine manipulation.
The objective of the invention is to, propose a kind of device that is used for strengthening bearing structure, it is conserve space not only, and is particularly suitable for site assembly, promptly at the construction field (site) the assembling, have or do not have pretension can, wherein assembling process is not only quick but also less demanding.
Another object of the present invention is, provides a kind of corresponding method.
According to the present invention, above-mentioned purpose can reach by the method described in device described in the claim 1 and the claim 10,11 and 13.The present invention will be described in detail by means of accompanying drawing below.Wherein:
