Description
Technical field
It the utility model is related to a kind of house rectifying by jack up technology, it is more particularly to a kind of for brick mix structure rectifying by jack up
Underpin buttress device.
Background technology
Caused by the inclination of building is mostly due to ground reason, or the Deformation control of shallow foundation is not good enough, or by
In pile foundation and basement process design, construction quality problem etc., rectifying of leaned building construction will influence foundation and superstructure
Stress, therefore correcting and then reinforcing design should analyze the reason for producing inclination, demonstration correction feasibility, to upper according to tale quale
Portion's structure carries out security evaluation, it is ensured that building safety.If the inclined raw of building is because including building load off-centring
Deng should prove the necessity of foundation stabilization, propose foundation reinforcement method, prevent from tilting once again.
Existing building correcting and then reinforcing method can be divided into forced falling rectifying deviation and the class of rectifying by jack up two.Forced falling rectifying deviation is entered from ground
Hand, by changing the virgin state of stress of ground, building is forced to sink；Rectifying by jack up is started with from building structure, passes through tune
Whole structure itself come meet correction purpose.
Rectifying by jack up is the structure underpinning technology by masonry, by the basis of building and superstructure along a certain spy
Fixed position is separated, and is reinforced using armored concrete, is segmented and underpins, form totally enclosed jacking transform beams（Post）Body
System.Several supporting-points of whole building thing can be supported by setting, and by the startup of the Lifting Equipment of these supporting-points, make building
Along a certain straight line（Point）Make Plane Rotation, you can corrected inclined building.If significantly adjust rising for each supporting-point
Amount, you can improve the absolute altitude of building.
When brick mix structure needs rectifying by jack up, need first to interrupt along ad-hoc location to be separated with building basis, Jin Er
The place's of interrupting casting concrete is reinforced, and after concrete setting reaches some strength, beams of concrete is entered by Lifting Equipment
Row jacking, so as to carry out rectifying by jack up to brick mix structure；Because masonry strength is relatively low, when entering Break Row to brick mix structure, upper strata
The easy avalanche of masonry, therefore invent and a kind of be to the buttress device that underpins that upper end brick mix structure is supported when interrupting brick mix structure
It is highly desirable.
Utility model content
The purpose of this utility model be to provide it is a kind of underpin buttress device for brick mix structure rectifying by jack up, have to brick
Mixed structure is supported, the advantages of avoiding brick mix structure avalanche.
Above-mentioned technical purpose of the present utility model technical scheme is that：
It is a kind of to underpin buttress device, including two supporting plates for brick mix structure rectifying by jack up, pass through between two supporting plates
Support column connects, and screw thread is combined with fastening bolt in supporting plate described in one, and the fastening bolt and support column are concentric
Set and along the displacement of support column height direction.
It is first uniform successively along brick mix structure length direction when brick mix structure is separated with foundation structure using said structure
Drill through some support slots, and then the one end for underpining buttress device and not having fastening bolt is positioned in support slot down, to upper end
Brick mix structure is supported, and then other junctions are all drilled through, so as to which in making an opening through place, binding reinforcing bars are then poured into coagulation
Soil, rectifying by jack up is carried out after concrete setting, then to brick mix structure；Because support slot is by strongly drilling through, highly have
Institute is different, coordinates adjustable distance between fastening bolt and supporting plate by the screw thread of fastening bolt and supporting plate, is suitable for pair
The support slot of different height is supported；And its upper end supporting plate is set to leave certain sky with upper end brick mix structure by fastening bolt
Gap, it is easy to reinforcing bar being held in supporting plate and is tied up.
More preferably：The support column is arranged to hollow pipe, and inside is filled with C40 grouting materials, in the support column
A hollow tube for fastening bolt grafting is provided with along axial line.
Using said structure, by being arranged to support column to fill C40 grouting materials in hollow pipe and support column, enhancing branch
Saving construction cost cost while the support strength of dagger；And then the hollow tube by being arranged in support column, make its fastening bolt
Can relative support post upper and lower displacement.
More preferably：The hollow pipe outer wall be additionally provided with along in its short transverse it is some make its hollow tube with support
The support frame of post keep level state.
Using said structure, hollow tube is supported by some support frames, its hollow tube is kept water with support column
Level state, it is easy to fastening bolt relative support post upper and lower displacement.
More preferably：A waist type groove is offered in the supporting plate, supporting plate upper surface is connected with one and fastening spiral shell
The clamp nut that bolt screw thread coordinates.
Using said structure, when assembling fastening bolt, first clamp nut screw thread is matched with fastening bolt, then will fastening
Bolt passes through waist type groove, inserts in hollow tube, and then clamp nut is fixed in supporting plate；Pass through the waist opened up in supporting plate
Type groove, it is easy in fastening bolt insertion hollow tube, reduces machining accuracy.
More preferably：The locating slot for support column grafting is offered in two supporting plates respectively.
Using said structure, by the locating slot opened up in supporting plate, it is easy to that support column quickly is fixed on into two supporting plates
On.
More preferably：The support column is provided with two and two support columns by supporting plate trisection.
Using said structure, by the way that support column is arranged into two and supporting plate is divided into three parts, make its stress more
Uniformly, enhancing underpins the support strength of buttress.
In summary, the utility model has the advantages that：
1st, coordinated by fastening bolt and support plate thread, can adjust the distance between fastening bolt and supporting plate, changed
The height of single unit system, reach the effect for adapting to be supported to the brick mix structure of different height；
2nd, by support column being arranged into hollow pipe and inside pours C40 grouting materials, enhancing support column support strength is reached
While reduce cost effect.
