Abstract
The utility model discloses a bearing body for single-pile static load test counter-force traction. The bearing body comprises a horizontal bottom plate and a cambered surface bearing plate. The cambered surface bearing plate is fixedly buckled on the horizontal bottom plate through a truss and formed by splicing three circular arc panels. The radius of the circular arc panel located in the middle is larger than the bending radius of a steel strand. The radius of the left circular arc panel and the radius of the right circular arc panel are smaller than the bending radius of the steel strand, wherein the left circular arc panel and the right circular arc panel are symmetrically spliced on the two sides of the circular arc panel located in the middle. The bearing body has the advantages that on the premise that the steel stand is fully protected by the bearing body, the stress state of connection of the steel strand of a cable-stayed structure and the bearing body is simplified, the stress of the steel strand is more uniform and more reasonable, and unsafe factors of a test are reduced.
Description
Technical field
The utility model relates to single-pile static loading test device, especially relates to the supporting body for single-pile static loading test counter-force tractive.
Background technology
Field of civil engineering, in order to provide reference frame or for checking engineering stake pile quality, General Requirements carries out single-pile vertical orientation static loading test to Pile Foundations Design.Single-pile static loading test must promising test provides the device of counter-force.Chinese utility model patent number is: ZL200520031724.9 discloses a kind of " dead load test on pile foundation counterforce device ", although the technical scheme structure stress that this patent is taked is reasonable, when but this patent adopts slant-pull structure transmitted load, the steel strand of transmitted load and supporting body are the both sides that are separately fixed at supporting body, the deficiency of its existence be steel strand and supporting body connecting portion intensity compared with low and easily disconnect, during heavy load, number of connection is more, the stressed complicated destructible of supporting body.
Summary of the invention
The utility model object is to provide a kind of supporting body for single-pile static loading test counter-force tractive.
For achieving the above object, the utility model is taked following technical proposals:
Supporting body for single-pile static loading test counter-force tractive described in the utility model, comprises horizonal base plate, by truss clip, is combined in the cambered surface loaded plate on described horizonal base plate, and described cambered surface loaded plate is spliced by three circular arc panels; The radius that is positioned at middle part circular arc panel is greater than the bend radius of steel strand, and symmetrical splicing is less than the bend radius of steel strand at the radius of the left and right circular arc panel of circular arc panel both sides, described middle part.
The utility model advantage is described supporting body to be arranged to be spliced by three circular arc panels, and the design radial of middle part circular arc panel is arranged to be greater than steel strand bend radius, like this, steel strand are walked around after cambered surface loaded plate, do not damaging under steel strand prerequisite, making it fully to contact transmitted load with middle part arc surface; And the design radial of the circular arc panel of arranged on left and right sides is less than steel strand bend radius, so that steel strand have sufficient space exposure, support transmitted load member and formed by truss and base plate, top supporting body and the load that bears are delivered on the jack of bottom.Therefore, supporting body is adequately protecting on steel strand basis, has simplified the stress that slant-pull structure steel strand are connected with supporting body, makes steel strand stressed more evenly rationally, has reduced test unsafe factor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, supporting body for single-pile static loading test counter-force tractive described in the utility model, comprise horizonal base plate 1, by truss 2 clips, be combined in the cambered surface loaded plate on described horizonal base plate 1, described cambered surface loaded plate is spliced by three circular arc panels; The radius that is positioned at middle part circular arc panel 3 is greater than the bend radius of steel strand, and symmetrical splicing is less than the bend radius of steel strand at the radius of the left and right circular arc panel 4,5 of circular arc panel 3 both sides, described middle part.
