Description
Technical field
The invention belongs to pile bearing capacity Static Test Technique field, and in particular to one kind is applied to pile bearing capacity static load
The pile crown of anchor pile or uplift pile in experiment stretches out reinforcing steel bar connecting device.
Background technology
Pile foundation is a kind of most commonly used base form of domestic application, and its construction quality directly influences superstructure
Safety.Pile bearing capacity static test is by applying continuing load, record load, displacement and time step by step in test pile stake top
Relation, so as to analyze, determine the bearing capacity of single pile.Therefore pile bearing capacity static test is to ensure that construction quality must can not
Few technological means.Pile bearing capacity static test is individually placed to design and constructed two stages in most cases, that is, before constructing
Foundation is provided for design, the engineering pile detection after construction then provides foundation for the acceptance of work.
Current foundation pile static loading test is generally using anchoring pile resistance to plucking counter-force (i.e. anchored pile-testing method) and heap weight counter-force platform two ways.
Static load test counter-force is provided for anchored pile-testing method, is that anchoring pile pile body steel reinforcement cage cage bar is connected by way of welding in the prior art
In girder steel two ends, not only welding job amount is big for this connected mode, and test platform sets up that the time is long, and efficiency is low, and site welding
Connect quality and be difficult to ensure card, it is asymmetric to may result in primary and secondary beam stress, influence test accuracy, serious meeting causes test platform unstability
Topple, therefore urgently improve.
The content of the invention
In order to overcome and avoid weak point of the prior art, the present invention proposes that a kind of pile bearing capacity static load that is used for is tried
The pile crown tested stretches out reinforcing steel bar connecting device.The present invention is simple in construction, construction is reasonable, it is to avoid it is cumbersome that pile crown stretches out reinforcement welding etc.
Process, in-site installation and convenient disassembly improve the efficiency that foundation pile test platform is set up and dismantled, it is ensured that test platform
Stability.
In order to realize the purpose of the present invention, present invention employs following technical scheme：

Draw rod attachment part, the bolt hole is arranged at draw rod attachment part；The backing plate lid is located at the upside of the inner ring and outer rings, pad
Plate is provided with stretches out the backing plate through hole that reinforcing bar stretches out for pile crown；It is described logical that the conversion through hole connects composition with backing plate through hole correspondence
Hole；The fixture is arranged on the top of the backing plate.
It is preferred that, the conversion connection member is provided with some connection floors, the connection rib between inner ring and outer rings
Plate radially connects inner ring and outer rings, and this some connection floor is equably laid between inner ring and outer rings along ring, adjacent
The conversion through hole of sector is constituted between connection floor.
It is preferred that, the backing plate is that the backing plate through hole on annular shape, the backing plate is set with the conversion through hole one-to-one corresponding
Put.
It is preferred that, the draw rod attachment part is set to two, and two draw rod attachment parts are symmetricly set on the both sides of outer shroud.
It is preferred that, the fixture is self-locking clamp.
It is further preferred that the backing plate through hole is Long Circle or oval, and backing plate through hole length direction along pad
The radial direction of plate is set.
It is further preferred that the draw rod attachment part includes otic placode and deep floor affixed each other；The plate of the otic placode
Face is fixedly connected perpendicular to the axial direction of inner ring and outer rings, and one end of otic placode with outer shroud, and the other end prolongs to the side away from outer shroud
Stretch and suspend；The deep floor is set to parallel to each other several of plate face, and the plate face of deep floor is perpendicular to the otic placode
Plate face, and the plate face of deep floor and the axial direction of outer shroud are parallel, and one end of the deep floor is fixedly connected with outer shroud, separately

2) conversion connector in the present invention is made up of conversion connection member and backing plate.The conversion connection member is on the one hand
It is engaged and is constituted with fixture against cooperation with backing plate, the connection realized with crossbeam is on the other hand then engaged with pull bar.It is described
Backing plate is then used to increase lifting surface area, so as to be conducive to effectively passing to load the conversion connection member of lower section.In the present invention
Conversion connection member and backing plate be fitted to each other, not only greatly simplifie structure, and make conversion connector whole as one
Body construction is more reasonable, is more uniformly stressed.
3) the conversion connection member in the present invention is made up of inner ring, outer shroud, connection floor and the part of draw rod attachment part four.Institute
It is the cartridge being arranged concentrically to state inner ring, outer shroud.The connection floor is connected between inner ring, outer shroud, so that adjacent company
Form the conversion through hole of larger fan shape between rib plate, the conversion through hole of this fan shape is larger due to gap, therefore just
Reinforcing bar is stretched out in pile crown to pass through, it is easy for installation.The steel that conversion connection member making in the present invention is used are few, and light weight is made
Valency is relatively low and reasonable stress.
4) Long Circle or ovate backing plate corresponding with fan-shaped conversion through hole is offered on the backing plate in the present invention
Through hole, is equally easy to pile crown to stretch out reinforcing bar and passes through, convenience quick for installation；The backing plate through hole is set to Long Circle or oval not
But the consumption of steel can be reduced, and advantageously reduces stress concentration phenomenon, the service life of backing plate can be effectively improved.
5) draw rod attachment part in the present invention includes otic placode and deep floor affixed each other；Otic placode and deep floor are each other
Cooperation can effectively improve structural strength.The bolt passed through for pull bar is offered on otic placode between adjacent deep floor
Hole, the bolt hole is opened in the end of otic placode, and the side towards end part of lug plate of bolt hole is opening shape.This side band
The bolt hole for having opening is easy to the installation and regulation of pull bar, adjustable along the lengthwise location of bolt hole just because of pull bar,
So as to which The present invention reduces the situation of load beam eccentric force, it is ensured that the symmetry of girder or secondary beam two ends stress and experiment are flat
The security and stability of platform.
6) fixture in the present invention is self-locking clamp, specifically, and self-locking clamp is by chuck body and from screw-type
Intermediate plate is constituted, and pile crown is stretched out after the chuck body that reinforcing bar is passed through on annular backing plate, and correspondence bar diameter is put into chuck body
Intermediate plate, after chuck body stress, intermediate plate will tightly pin pile crown stretch out reinforcing bar, so as to drastically increase the jail of connection
Solidity.
