In the prior art, for the connection of static load of pile foundation lotus experimental rig, method commonly used is the dowel welding.When carrying out the vertical compression test, jack is placed on the test pile, and the upper end of jack contacts with the reaction frame center that girder steel is formed, and the reaction frame outer end of being made up of girder steel is connected with anchoring pile with annular steel drum by welding matrix steel plate, screw-thread steel; Carrying out vertically pulling-resistant when test, the jack of two same models is placed on the anchoring pile with the test pile symmetry, girder steel is laid in the jack top, welds matrix steel plate, screw-thread steel and annular steel drum again test pile is connected with girder steel.Being connected all by parts such as reinforcing bar welding realization of girder steel and test pile in being connected of reaction frame and anchoring pile, the resistance to plucking test in the compression test.This form wide adaptability be fit to the connection of the static loading test device of multiple stake such as pile tube, castinplace pile type, but field requirement has the source of welding current, needs to be equipped with welding personnel and the equipment of specialty; The consumptive materials such as welding rod and reinforcing bar of need purchasing; It all is existing problem in the practical application that welded and installed and dismounting such as lengthen at the test period.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of pile for prestressed pipe vertical static loading test device, with the installation that realizes fast and simple experimental rig, reduce experimentation cost and increase work efficiency.
The design feature of the vertical static loading test device of the utility model pile for prestressed pipe is:
The resistance to plucking terminal pad that is complementary with the stake type is set, and described terminal pad is connected with pile body with stretch-draw screw in the pile crown end plate by bolt;
"T"-shaped pull bar is set, and described "T"-shaped pull bar is inverted in the pile tube pore by the oblong openings at terminal pad center, with horizontally rotate 90 ° "T"-shaped pull bar on carry and tangle terminal pad;
The chuck that setting is made up of slip spider and dovetail slip fixes bar portion at described "T"-shaped pull bar with described chuck, will act on the force transmission that makes progress that the jack of described slip spider or girder steel below produces by described "T"-shaped pull bar and give pile body.
The vertical static loading test device of the utility model pile for prestressed pipe is characterized in that: described chuck can fix on the bar portion desired height position of described "T"-shaped pull bar.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model uses terminal pad and bolt to finish and being connected of pile body, and installing/dismounting only need be tightened or unclamp bolt and get final product, need not to weld and cut and tear open, and greatly easy disassembly process has shortened the test period, has improved test efficiency effectively; Terminal pad and bolt can be reused, and have reduced material consumption, have saved experimentation cost;
2, the utility model uses "T"-shaped pull bar by the oblong openings realization pile body at terminal pad center and being connected of top, can temporarily send into pile tube pore in temporary fixed by the terminal pad oblong openings long "T"-shaped pull bar during installation, avoided long "T"-shaped pull bar to establish above pile body, installed for other testing equipment and make troubles.With use the welding of screw-thread steel arrangement of reinforcement to compare to have saved material consumption and installation work-hour especially, "T"-shaped pull bar can infinitely be reused;
3, the chuck be made up of slip spider and dovetail slip of the utility model is connected with "T"-shaped pull bar, safely, fast, need not welding, can need the position to fix "T"-shaped pull bar arbitrarily, make test more wide in range to the requirement of the test pile depth, the setting height(from bottom) of test jack is also unrestricted, need not to use as other installation and connection method the steel cushion block to adjust jack test height again.
