Abstract
The utility model belongs to the construction machinery field relates to a counterforce device for foundation pile resistance to compression static test. The device includes the jack, and the top of jack is provided with a supporting beam, and load is evenly stacked to a supporting beam top, is buttresses in a supporting beam's below both sides, characterized by: it is connected as an organic wholely to pass through connecting device at a supporting beam with the buttress. The utility model discloses an advantage embodies through erection joint on the secondary beam to the connecting device of buttress for the weight of heavy object and buttress can be used in test on the platform, the counter weight availability factor is improved, reduce the weight of the heavy object on the platform, can effectively reduce too bigly because of heap loading capacity, arouse that the secondary beam warp the probability of the incident that causes.
Description
Technical field
This utility model belongs to building machinery field, is related to a kind of counterforce device for foundation pile compressive static load test.
Background technology
In static test, the load acting in stake is typically provided by counterforce device.The easy-to-use degree of counterforce device is direct
Affect process and the result of test, conventional has ballasting platform counterforce device.Ballasting platform counterforce device is exactly to make in stake top
One bearing platform, upper heap weight are set with girder steel, rely on and be placed on the jack on pile crown by platform progressively jack-up, thus power is applied
It is added to pile body.Existing ballasting platform counterforce device is that weight is placed on the buttress of both sides, and this is general contemporary devices.Mainly
Deficiency is to only used weight on platform, and the weight of buttress does not use, and counterweight service efficiency is low.
Content of the invention
Main purpose of the present utility model is：There is provided a kind of counterforce device of foundation pile compressive static load test so that in base
The weight of weight and buttress on platform can be used, it is possible to increase counterweight service efficiency and detection effect in stake compressive static load test
Rate.
In order to reach the above object, basic technical scheme of the present utility model is：A kind of foundation pile compression dead load that is used for tries
The counterforce device tested, including jack, the top of jack is provided with support beam, uniformly stacks load, propping up above support beam
The lower section both sides of support beam are buttresses；It is characterized in that：Connected as one by attachment means with buttress in support beam.
Described attachment means include medicated pillow beam, inserted sheet, sleeve, grade beam；Described medicated pillow beam is located at buttress position
Support on top surface of the beam, its two ends is stretched out support beam both sides and is connected with two inserted sheet upper ends respectively；The hypomere setting of two inserted sheets
The pin hole of level, is enclosed within two inserted sheet hypomeres and by slotting with what pin hole coordinated positioned at two sleeve upper ends of buttress both sides
Pin is connected with inserted sheet；Described grade beam is located at buttress subjacent, and grade beam is provided with a pair of contiguous block positioned at buttress both sides, institute
The jack hole stating contiguous block with two sleeve lower ends is connected by latch.
Pin hole on described inserted sheet is from top to bottom provided with multiple.
Advantage of the present utility model is embodied in：1st, by support beam and buttress are connected as a single entity, can use flat in test
The weight of weight and buttress on platform, improves counterweight service efficiency；2nd, reduce the weight of the weight on platform, can effectively reduce because of heap
Loading capacity is excessive, causes support beam to deform the probability of the security incident causing.3rd, effectively increase the efficiency of static loading experiment.

Specific embodiment
As illustrated, the counterforce device that this is used for foundation pile compressive static load test includes jack 9, the top of jack 9 sets
It is equipped with support beam 5, uniformly stack load 7 above support beam, be buttress 2 in the lower section both sides of support beam 5；Support beam 5 with
Pier 2 is connected as one by attachment means.Attachment means include medicated pillow beam 6, inserted sheet 4, sleeve 3, grade beam 1；Described medicated pillow beam 6
On support beam 5 top surface of buttress position, its two ends is stretched out support beam both sides and is connected with two inserted sheet 4 upper ends respectively
Connect；The hypomere of two inserted sheets arranges the pin hole 41 of level, and two sleeve upper ends positioned at buttress both sides are enclosed within two inserted sheets
Section and by being connected with inserted sheet with the latch that pin hole coordinates；Grade beam 1 is located at buttress subjacent, grade beam is provided be located at and props up
A pair of contiguous block 11 of pier both sides, described contiguous block is connected by latch with the jack hole of two sleeve 3 lower ends.On inserted sheet 4
Pin hole 41 be from top to bottom provided with multiple, can selectively with sleeve connection, with adjust connect height.
During work, by loading jack 9, by support beam 5 jack-up, medicated pillow beam 6 is placed in support beam 5, in support beam
Stack load 7, medicated pillow beam 6 both sides ledge is inserted into the square in the hole of inserted sheet 4 top, and is fixed with bearing pin.Under inserted sheet 4
Duan Yousan circular hole, sleeve 3 is enclosed within the outside of inserted sheet 4, and sleeve 3 also comprises 2 circular holes, adjusts the position of inserted sheet 4 and sleeve 3,
According to practical situation, select the hole on inserted sheet 4 can be coupled together inserted sheet 4 and sleeve 3 with latch.The lower end of sleeve 3
It is inserted in the fixing hole of grade beam 1, and fixed with latch.Buttress 2 is placed on grade beam 1, can be by buttress 2 by attachment means
It is connected with support beam 5 so that the weight of weight and buttress on platform can be used in test, improve counterweight using effect
Rate.
