Description
Technical field
The invention belongs to pile bearing capacity Static Test Technique fields, and in particular to a kind of integrated form foundation pile static loading test is anti-
Power beam.
Background technology
The loading equipemtn of foundation pile static loading test --- hydraulic jack is discrete with the girder in counterforce device, is showed at present
When the installation of field, jack need to be first installed, then girder is installed.Due to the horizontal centring between jack and girder, down suction
There are strict demand, installation process relatively complicated.Moreover, this mounting means can lead to entire counterforce device mounting height relatively
Height is unfavorable for safety.
In addition, according to related specification requirement, as measurement instrument, the re-testing periods of above-mentioned hydraulic jack are half a year.By
In current technology, does not have and on-site proving condition in situ is carried out to jack, it is necessary to periodically send to legal calibrating department and carry out
Calibrating.This can not only increase calibrating cost, but also can greatly reduce the service efficiency of equipment.
Invention content
In order to overcome and avoid shortcoming in the prior art, the present invention to propose that a kind of integrated form foundation pile static loading test is anti-
Power beam.The present invention is simple in structure by foundation pile static loading test loading equipemtn --- hydraulic jack is combined into one with reaction beam, construction
Rationally, the mounting process for improving the load counter-force equipment of foundation pile static loading test, reduces mounting height, improves safety.
The present invention can also be realized simultaneously carries out in-situ test to hydraulic jack, reduces calibrating cost, improves equipment service efficiency.
In order to achieve the object of the present invention, present invention employs following technical schemes：
A kind of integrated form foundation pile static loading test reaction beam, this reaction beam include beam body, are provided with and are used for and liquid in the beam body
The bolt hole for pressing jack connection is additionally provided with matched with the columns assemblies for jack in-situ test in the beam body
Wire hole and technical gaps；The invention also includes hydraulic jacks and connection bolt, the hydraulic jack cylinder base to be provided with
With connect the matched wire hole of bolt.
Preferential, the beam body includes two girder steels being arranged symmetrically and component beam.Two girder steels being arranged symmetrically,
It is provided with and the matched wire hole of columns assemblies for jack in-situ test, and the two symmetrical cloth in its bottom
The girder steel set is provided with corresponding technical gaps in its web with the bottom wire hole corresponding position.The component beam, laterally
It is arranged in the middle and upper part of beam body, is welded with the top flange of two girder steels being arranged symmetrically, web, is formed whole.Described point
The bolt hole for being connect with hydraulic jack is provided on power lower flange of girder edge.
Preferential, described hydraulic jack, using two with model jack along the longitudinally asymmetric cloth of the reaction beam
Set, every jack cylinder body bottom symmetrical be arranged two with connect the matched wire hole of bolt.
The beneficial effects of the present invention are：
1）The present invention is integrated into an entirety by hydraulic jack is loaded with reaction beam, and bulk handling, transport significantly improve
The mounting process of experiment load counterforce device.Due to jack retraction beam body, set to significantly reduce entire load counter-force
Standby mounting height improves safety.
2）The present invention utilizes the construction features of beam body, is equipped with columns assemblies and crossbeam accordingly for jack calibrating,
Just in-situ test can be carried out to jack.Both calibrating cost had been reduced, more can greatly improve the service efficiency of equipment.
3) beam body of the present invention uses couple structure, and whole depth-width ratio is relatively low, and transport and mounting stability are good, hydraulic jack
Installation and maintenance it is also very convenient.
