Abstract

The invention provides a circular pull-out test supporting device, and relates to an auxiliary device in a pull-out test.The circular pull-out test supporting device comprises a support ring and a wedge-shaped cushion block, the support ring comprises a bottom plate, a top plate and support ribs, the bottom plate and the top plate are each a circular steel plate, the bottom plate is larger than the top plate, the support ribs are connected between the bottom plate and the top plate in an inclined mode, the bottom end of each support rib is connected to the upper surface of the bottom plate, and the top end of each support rib is connected to the lower surface of the top plate; a penetrating through hole is formed in the middle of the wedge-shaped cushion block, the bottom face of the wedge-shaped cushion block is a plane perpendicular to the axis of the through hole, and the top face of the wedge-shaped cushion block is an inclined plane which is not perpendicular to the axis of the through hole.When the circular pull-out test supporting device is adopted for conducting an anchor bolt pull-out test, the circular pull-out test supporting device effectively supports a jack, destruction of a concrete wall surface is avoided, whether an anchor bolt is perpendicular to the concrete wall surface or not, it can be effectively guaranteed that the center line of an oil cylinder of the jack is basically overlapped with the axis of the anchor bolt, the jack is prevented from being subjected to eccentric force, and the detection precision is improved.

Description

Circular pull-out test props up support arrangement
Technical field
The present invention relates to a kind of auxiliary device in pull-out test, particularly to a kind of anchor rod drawing experiment supporting device.
Background technology
When carrying out anchor rod drawing testing inspection, it is necessary to clamp anchor pole to detect anchor pole anchor anchor-hold in concrete with jack, jack is directly born against concrete wall surface and detects, it is easy to destroy concrete wall surface；It addition, owing to a lot of anchor poles and metope are not vertically arranged in actually detected process, when clamping anchor pole with jack, it is difficult to ensure that the dead in line of the oil cylinder centrage of jack and anchor pole, it is easy to cause eccentric tension, and affect accuracy of detection.
Summary of the invention
It is an object of the invention to provide a kind of circular pull-out test and prop up support arrangement, when anchor rod drawing is tested, effective support jack avoids damage to concrete wall surface, essentially coincide regardless of the axis of the anchor pole oil cylinder centrage and anchor pole that can be effectively ensured jack whether vertical with concrete wall surface, avoid jack eccentric force, improve accuracy of detection.
The present invention the technical scheme is that a kind of circular pull-out test props up support arrangement for achieving the above object, including pushing out ring and a correcting wedge, prop up pushing out ring and include base plate, top board and ribs, the steel plate of base plate and top board respectively annular, base plate is bigger than top board, ribs tilts to be connected between base plate and top board, the bottom of ribs is connected to the upper surface of base plate, ribs top is connected to the lower surface of top board, the through hole that the middle part of correcting wedge is provided with through, the bottom surface of correcting wedge is plane orthogonal with through-bore axis, the end face of correcting wedge is and through-bore axis off plumb inclined plane.
Circle pull-out test of the present invention props up support arrangement and has the advantages that the steel plate of base plate and top board respectively annular, the base plate propping up pushing out ring is bigger than top board, when detecting the anchor pole vertical with concrete wall surface, anchor pole is through propping up a pushing out ring, jack can be positioned on cover top surface and anchor pole detected, need not directly be against on mixed earth metope, it is to avoid jack destroys concrete wall surface；When detection is with concrete wall surface off plumb anchor pole, prop up pushing out ring and be against on mixed earth metope, select the correcting wedge identical with anchor pole angle of inclination again, correcting wedge bottom surface leans against support ring top board upper surface, jack can be positioned on and on correcting wedge end face, anchor pole detected, biased one and anchor pole angle of inclination equal angular by correcting wedge end face after, it is ensured that the oil cylinder centrage of jack and the axis of anchor pole essentially coincide, avoid jack eccentric force, improve accuracy of detection.
Below in conjunction with drawings and Examples, circle pull-out test of the present invention is propped up support arrangement to be further described.

Drawing reference numeral illustrates: 1-props up pushing out ring, 2-correcting wedge, 3-base plate, 4-top board, 5-ribs, 6-through hole, 7-jack, 8-anchor pole.
Detailed description of the invention
As shown in Figure 1 to Figure 3, circle pull-out test of the present invention props up support arrangement (being called for short " support arrangement "), and including pushing out ring 1 and a correcting wedge 2, a pushing out ring 1 includes base plate 3, top board 4 and ribs 5.The steel plate of base plate 3 and top board 4 respectively annular, base plate 3 is bigger than top board 4, ribs 5 tilts to be connected between base plate 3 and top board 4, a plurality of ribs 5 uniformly it is placed with between base plate 3 and top board 4, the bottom of ribs 5 is connected to the upper surface of base plate 3, ribs 5 top is connected to the lower surface of top board 4, and ribs 5 is to be connected with base plate 3 and top board 4 respectively by the mode welded.The through hole 6 that the middle part of correcting wedge 2 is provided with through, correcting wedge 2 is generally cylindric, and through hole 6 is circular hole, and the bottom surface of correcting wedge 2 is and the through hole 6 orthogonal plane of axis, and the end face of correcting wedge 2 is and through hole 6 axis off plumb inclined plane.
When carrying out anchor rod drawing test, if detect the anchor pole vertical with concrete wall surface, as shown in Figure 4, have only to use a pushing out ring 1, without using correcting wedge 2, anchor pole 8 is through a pushing out ring 1, and jack 7 can be positioned on top board 4 upper surface and anchor pole 8 is detected, need not directly be against on mixed earth metope, it is to avoid jack 7 destroys concrete wall surface.If when detection and concrete wall surface off plumb anchor pole, as shown in Figure 5, need to use pushing out ring 1 and a correcting wedge 2 simultaneously, and select the correcting wedge 2 identical with anchor pole 8 angle of inclination, correcting wedge 2 bottom surface leans against pushing out ring 1 top board 4 upper surface, jack 7 can be positioned on and on correcting wedge 2 end face, anchor pole 8 detected, biased one and anchor pole angle of inclination equal angular by correcting wedge 2 end face after, ensure that the oil cylinder centrage of jack 7 essentially coincides with the axis of anchor pole, avoid jack eccentric force, improve accuracy of detection.
Above example is only presently preferred embodiments of the present invention, and the structure of the present invention is not limited to the form that above-described embodiment is enumerated, all make within the spirit and principles in the present invention any amendment, equivalent replacement etc., should be included within protection scope of the present invention.
