Description
Technical field
Technical field of engineering equipment is the utility model is related to, more particularly to a kind of adjustable-height support.
Background technology
Connection for concrete component, particularly for huge concrete structure, the multiple section assemblings of generally use
Mode reaches connection purpose, this allows for each segment needs to be moved after completing, and is moved to segment to be connected
It is attached.In movement, generally use support jack coordinates the mode of pushing tow jack, to realize the shifting of concrete component
It is dynamic：Concrete component is supported by multiple support jacks, by pushing tow jack along slide to concrete component into
Row pushing tow.
After concrete component is moved to designated position along slide, Program for structural Transformation need to be carried out, it is mixed by being arranged on
The support jack of concrete component and pushing tow jack are replaced out by the buttress on solidifying soil component, and by two adjacent segments
Concrete component on buttress fasten come load-bearing stress.
However, in order to realize being fastened and connected between two concrete component buttresses, exist between the buttress mutually fastened
Gap, when concrete component adjustment positioning after need remove support jack when, due to upper and lower two it is adjacent between buttress deposit
In gap, and can not achieve the adjustment of bearing height between buttress, that is, buttress height cannot well with concrete component
Interval between concrete buttress is adapted, and resulting in relying on bearing in itself can not be unstable by the support of concrete component, support
Power is inadequate, can not ensure that structural system replacement process is smoothed out.
In addition, when two components are being fastened and connected by the bearing for being arranged on adjacent end portion, to ensure that connection is set
Gap is put,, can be in the interstice coverage of bearing between two components if retention gap between two bearings after completing to connect
It is interior to be mutually shifted, cause structure unstable, or even the problem of damage connects bearing.
Therefore, the gap between two bearings being used to support or connect how is solved, becomes and effectively realizes structural system
Conversion, and ensure the key for not being mutually shifted, misplacing after component connection.
Utility model content
The goal of the invention of the utility model is：For between two components set bearing be used to support and connect when,
A kind of the problem of during due to leading to not complete support and connection there are gap between bearing and component, there is provided height-adjustable branch
Seat, the adjusting bearing by set coarse adjustment plate carry out coarse adjustment, be additionally provided with adjuster, take slip casting adjust by way of,
Adjusting bearing is set to reach the height and position of setting, which realizes by pressure controlled mode and control to adjust height
Purpose, easy to operation and control, and after being adjusted in place, will not spring back or fail, reach permanent support or the effect of connection
Fruit.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of adjustable-height support, including rack and rinion adjustment and the adjuster with the rack and rinion adjustment arranged superposed, its
In：
The rack and rinion adjustment includes the coarse adjustment plate of polylith arranged superposed, the sum of thickness of coarse adjustment plate described in polylith with it is to be adjusted
Clearance fit；

Amount has multiple again, according to the width in gap to be adjusted, the type and quantity of coarse adjustment plate is reasonably selected, so as to complete coarse adjustment.
Inside airtight cavity slip casting by injected hole toward mounting seat, makes sealing-plug under the pressure of slurries with installing bottom
The inner wall of seat is moved, so as to move towards coarse adjustment plate side, makes to be adjacent between sealing-plug and coarse adjustment plate, real there is no gap
Existing accurate adjustment.When slip casting adjusts height of support, according to gap adjustment requirement, by controlling the pressure of slurries to realize adjustment amplitude
Control, can reach preferable regulating effect.After accurate adjustment is adjusted in place, keep pressure constant, can be realized after grout cures permanent
Support or the effect of connection, ensureing the height of bearing there is a situation where springing back, reducing, will not fully realize the fixation of height.
In conventional adjustment means, generally use wedge block is adjusted, and adjusting makes, and is inserted wedge block by force using impact force
Between entering adjacent two plates, this regulative mode can not only cause damage plate and wedge block, influence its long-time service, together
When be difficult control adjustment width, when exist excessively adjust when, next step adjusting can not be carried out, and take grouting mode carry out essence
Adjust, relative motion by a small margin can only occur between sealing-plug and mounting seat, and slowly adjusted by slurry pressure, to whole
Bearing is protected well, improves the service life for adjusting bearing, meanwhile, grouting pressure is adjusted, can also release injection
Slurries so that well control adjustment width.
In addition, traditional approach also have using screw rod coordinate rotating nuts wedge block is squeezed between plate by the way of into
Row is adjusted, and screw rod is easy to fail in this regulative mode, after screw failure, can not be adjusted, also, this adjusting side
Formula is also the mutual extruding relied between adjustable plate, slides, is not easy to control and regulation amplitude, is also easily damaged adjustable plate.
Preferably, cushion block corresponding with housing depth, the cushion block and the mounting seat are equipped with the airtight cavity
Internal chamber wall fitting.
By setting cushion block in sealing cavity, so that the gap in airtight cavity is reduced, when injecting slurries, slurries
