Description
Technical field
The utility model belongs to architectural engineering detection field, more particularly to a kind of large-section in-situ concrete pile pulling resistance testing device.
Background technology
Pile foundation can produce the situation of pulling out, when soil body frictional force by the case of descending water or horizontal loading larger higher
When being insufficiently resistant to uplift force, pile foundation can produce destruction, and then influence to need to check this in the safety of superstructure, therefore design
When uplift bearing capacity.At present, the pullout tests for large-section in-situ concrete pile detect that main is all simulating load multistage loadings
Method tested, comparatively, the withdrawal resistance bearing value of large-section in-situ concrete pile is big compared with pile tube, used equipment and
The device for providing counter-force also requires that higher, traditional large-section in-situ concrete pile pulling resistance testing device safety coefficient is low, discontinuity,
Obtained test data is forbidden, and is easily caused edge reinforcement fracture, threatens the life security of testing crew.
Utility model content
The purpose of this utility model is to provide a kind of large-section in-situ concrete pile pulling resistance testing device, and the experimental rig stress is equal
Even, test data is accurate, and safety coefficient is high.
To achieve these goals, the utility model is adopted the following technical scheme that：
Stress dress is additionally provided with a kind of large-section in-situ concrete pile pulling resistance testing device, including crossbeam and jack, the crossbeam
Put.
Further, the stressing device is half cylindrical structure.
Further, the stressing device raw material are armored concrete or steel.
Further, hook is additionally provided with the stressing device, it is convenient to install, dismantle and transport.
Further, the crossbeam is rectangular configuration.
Further, the crossbeam raw material are armored concrete or steel.
Further, the jack is hydraulic jack or hydraulic jack.
Compared with prior art, the utility model has the following advantages that：
A kind of large-section in-situ concrete pile pulling resistance testing device of the present utility model, design science rationally, is added on crossbeam
The stressing device of one half cylindrical structure, the stressing device can make reinforcing steel bar bear uniform, it is not easy to be broken, the whole dress of enhancing
The safety coefficient put；And it can also make experimental rig uniform force, obtain more accurate test data；Set on stressing device
Hook, facilitate the installation and removal of experimental rig, it is simple to operate.
Brief description of the drawings
Fig. 1 is the schematic diagram of a preferred embodiment.
Fig. 2 is the sectional drawing of a preferred embodiment.
Embodiment
A kind of large-section in-situ concrete pile pulling resistance testing device of the utility model is made below in conjunction with specific embodiment and accompanying drawing
It is described in further detail.
As shown in figure 1, in a preferred embodiment, a kind of large-section in-situ concrete pile pulling resistance testing device of the present utility model includes
One crossbeam 1 and two jack 2, are additionally provided with a stressing device 3 on crossbeam 1, and the stressing device is semi-cylindrical knot
Structure, the present embodiment middle cross beam 1 and the raw material of stressing device 3 are armored concrete, with low cost, can be according to different size of
Pile foundation is customized.
Because the volume of stressing device 3 is larger, heavier-weight is all inconvenient using manpower installation and removal, so in stress
The two ends of device 3 are equipped with a hook 4, facilitate mechanically actuated.
What jack 2 was selected in the present embodiment is hydraulic jack, and cost is relatively low, easy to use.
When specifically used, first stressing device 3 is arranged on crossbeam 1, crossbeam 1 and stressing device 3 are placed in stake together
The surface of base 5, and through the reinforcing bar 6 in pile foundation 5, make the uniform branch of reinforcing bar 6 on stressing device 3, finally will with machinery
Crossbeam 1 is lifted, and is respectively put into a jack 2 at the two ends of crossbeam 1, is played a supporting role, is resisted by adjusting jack 2
Pull out experiment.
The utility model design science is rationally, simple in construction, uses easy to operate, the stress dress of half cylindrical structure
3 are put so that experimental safe coefficient is greatly improved, and makes device uniform force, more accurate test data is obtained.
Although being to combine embodiments above to carry out to description of the present utility model, it is familiar with the art
Personnel many replacements, modifications and variations can be carried out according to above-mentioned content, are obvious.Therefore, it is all such
Substitute, improve and change and be included in the spirit and scope of appended claims.
