Abstract
The present invention relates to a kind of FRP networks for reinforcing wall, it is characterised in that：Including wall, FRP grids, pad, shear connector；Wherein described FRP grids are fixed on the surface of wall；The shear connector is arranged in the grid hole of the FRP grids；The wall is inserted in one end of the shear connector；The pad is arranged between the shear connector and the FRP grids.The present invention has the advantages that the characteristics of simple, simple operation is efficient.FRP shapes can flexible design, meet the shape need of various reinforcing walls or bank protection.This method can effectively improve the anti-side rigidity and globality of original wall body or bank protection, make it have more preferable bearing capacity, while hardly increasing own wt.Wall is improved to a certain extent or bank protection resists the ability of horizontal direction active force, the possibility of crack appearance is largely reduced, and is a kind of simple, economic reinforcement means.
Description
Technical field
The invention belongs to technical field of buildings, the new structure and method of particularly a kind of reinforcing wall or bank protection.
Background technology
Wall is armored concrete due to itself founding materials, with stability is strong, surface strength is good, globality is preferable,
The characteristics of meeting the aesthetic conceptions of people simultaneously, wall is also more and more applied to various building structure.Although wall has a lot
Advantage, but with the intensification of level of application, its some shortcomings and defect are also gradually revealed, and wall resistance horizontal direction is made
Ability firmly is poor, the self structure of wall is own wt is big, node reinforcement ratio it is relatively low in the case of, it is difficult to ensure that skyscraper
The quality requirement of construction, if slight crack also easily occurs in construction wrong, is threatened to residenter house safety belt, wall quality
Lifting can largely improve the total quality of skyscraper.Therefore, the quality of lifting wall has important actual meaning
Justice.
At present, mainly have to the reinforcement means of wall both at home and abroad：Bonding steel plate method, CFRP Sheet Strengthening Method, grouting and reinforcing method
Deng.These reinforcement means all play certain effect for wall reinforcement, but difficulty of construction is larger, and cost is very high.In addition
The method that also steel wire reinforces shear wall, this method is similar to the principle of this patent, but because steel wire is in moist environment
Under compare the easy corrosion of FRP grids, and conduct oneself with dignity than larger, the performance such as anticorrosive, antifatigue is good not as good as FRP material.Therefore, originally
It is a kind of simple, economic reinforcement means that patent, which provides FRP grids reinforcing wall or the method for bank protection,.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, this patent, which is provided, utilizes FRP grids reinforcing wall or bank protection
Structure and construction method, it is the structure and reinforcement means that a kind of simple, simple operation is efficiently applied to wall or bank protection.
To achieve the above object, the technical scheme that this patent is used is：A kind of FRP grid knots for reinforcing wall
Structure, it is characterised in that：Including wall, FRP grids, pad, shear connector；Wherein described FRP grids are fixed on the surface of wall；
The shear connector is arranged in the grid hole of the FRP grids；The wall is inserted in one end of the shear connector；The pad is set
It is placed between the shear connector and the FRP grids.
Preferably, the wall is fixed with the outside of the side of FRP grids and is provided with concrete layer.
Preferably, the other end of the shear connector exposes surface of wall, and the pad, which encloses, is against the shear connector, and with institute
State shear connector and expose the end of wall and be brought into close contact.
Preferably, the pad is the sheet metal of flat.
The construction method that this patent is used is：
Step 1: determining the position that the FRP grids are fixed in the surface of wall；
Step 2: making marks and punching on metope in the grid hole of the FRP grids；
Step 3: the shear connector is implanted into the hole accomplished fluently, described one section of insertion surface of wall of shear connector, the other end
Expose the surface of wall；
Step 4: the position that the FRP grids according to step one are fixed in the surface of wall, the FRP grids are fixed on
On the surface of wall；
Step 5: installing the pad between the shear connector and the FRP grids, the pad exposes with the shear connector
The end of wall is brought into close contact；
Step 6: being fixed with the external application concrete layer of the side of FRP grids in the wall.
The present invention after adopting the above technical scheme, have the advantage that including：
This patent provides the structure and construction method using FRP grids reinforcing wall or bank protection, and it has simple, simple operation
Efficiently the characteristics of, FRP material in this patent is anticorrosive, anti-fatigue performance is good, in environment that can be special and moist at some
Use for a long time, thus the service life of structure can be improved, this is that structural material hardly matches.FRP material can mitigate structure
Deadweight, specific strength is very high（High-strength light）；FRP shapes can flexible design, meet the shape need of various reinforcing walls or bank protection.
This method can effectively improve the anti-side rigidity and globality of original wall body or bank protection, make it have more preferable bearing capacity, while several
Do not increase own wt.Wall is improved to a certain extent or bank protection resists the ability of horizontal direction active force, very big
The possibility of crack appearance is reduced in degree, is a kind of simple, economic reinforcement means.Easy construction, broad covered area.
Brief description of the drawings
Fig. 1 is construction schematic diagram.
1- shear connectors；2-FRP grids；3- pads；4- concrete layers.
Embodiment
For the feature and advantage of this patent can be become apparent, special embodiment below, and coordinate accompanying drawing, make specifically
It is bright as follows.
（1）First according to the situation for treating reinforcing wall, the specification of FRP grids is determined, FRP is manufactured according to standard construction process
Grid, the size reasonable of FRP grid specifications is applicable.
（2）Punching.FRP grids are attached to reinforcing wall surface to determine the position of punching, FRP grids is removed and carries out hole
The position mark in hole, according to the position of mark to wall drilling.The position of hole, quantity determines according to FRP grids, hole
Size, depth and shear connector match.
（3）Shear connector 1 is implanted into the hole that surface of wall is accomplished fluently according to standard construction process.
（4）FRP grids 2 are pasted according to standard construction process and arrive surface of wall, and pad 3, the gold that pad is planar as are installed
Belong to piece, pad is closely connected with shear connector outer end, under the collective effect of shear connector and pad, and FRP grids are fitted tightly over
Reinforcing wall surface.
（5）It is last to smear concrete layer 4, rendering wall in metope.
This patent is not limited to above-mentioned preferred forms, and anyone can show that other are each under the enlightenment of this patent
The utilization FRP grids reinforcing wall of the form of kind or the structure and construction method of bank protection, it is all to be done according to scope of the present invention patent
Impartial change and modification, should all belong to the covering scope of this patent.
