Abstract
A kind of easy device detecting withdrawal resistance, comprise reaction frame, the bottom of reaction frame is provided with for fixing expansion bolt, the top of expansion bolt is provided with dial gauge, reaction frame is forward and backward is respectively provided with a bearing, between two bearings, erection has bearing beam, and bearing beam is placed lifting jack and pressure transducer, lifting jack and pressure transducer are positioned at reaction frame.Structure of the present invention is simple, easy to use, can gather materials on the spot, and does not need to purchase a large amount of test equipments, is convenient to test and carries out.Except can measuring power numerical value that market instrument can measure, can also displacement be measured, and the displacement of maximum withdrawal resistance and correspondence when going out anchoring piece work by force-displacement curve figure observable, thus judge whether to meet job requirement.
Description
Technical field
The invention belongs to building field utility appliance, particularly relate to a kind of pick-up unit.
Background technology
There is the special instrument detecting withdrawal resistance in the market, for detecting the withdrawal resistance of the anchoring pieces such as various anchor pole, anchor cable, reinforcing bar, expansion bolt, the ultimate tensile strength (UTS) of anchoring piece can be measured, but in practical application, only detect, understand ultimate tensile strength (UTS) and be nowhere near, sometimes need to detect whether anchoring piece other conditions operationally meet job requirement, as displacement etc.Separately, the special instrument on market need be purchased specially, and buying trouble, practicality is low.
Summary of the invention
Technical matters to be solved by this invention is for the deficiency in background technology, provides a kind of easy device detecting withdrawal resistance.
In order to solve the problem by the following technical solutions: a kind of easy device detecting withdrawal resistance, comprise reaction frame, the bottom of reaction frame is provided with for fixing expansion bolt, the top of expansion bolt is provided with dial gauge, reaction frame is forward and backward is respectively provided with a bearing, between two bearings, erection has bearing beam, and bearing beam is placed lifting jack and pressure transducer, lifting jack and pressure transducer are positioned at reaction frame.
Described expansion bolt is for connecting reaction frame and concrete.
Described reaction frame is the quadra be welded by shaped steel.
Described bearing beam is made by channel-section steel.
Described bearing beam is provided with 50T lifting jack, and 50T lifting jack is provided with pressure transducer.
Structure of the present invention is simple, easy to use, can gather materials on the spot, and does not need to purchase a large amount of test equipments, is convenient to test and carries out.Except can measuring power numerical value that market instrument can measure, can also displacement be measured, and the displacement of maximum withdrawal resistance and correspondence when going out anchoring piece work by force-displacement curve figure observable, thus judge whether to meet job requirement.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is left view of the present invention.
Embodiment
As shown in Figure 1, 2, a kind of easy device detecting withdrawal resistance, comprise the quadra that is welded by shaped steel as reaction frame, the bottom of reaction frame is provided with expansion bolt, and expansion bolt is for connecting reaction frame and concrete.The top of expansion bolt is provided with dial gauge, and reaction frame is forward and backward is respectively provided with a bearing, and between two bearings, erection has the bearing beam be made by channel-section steel, and bearing beam is placed 50T lifting jack, 50T lifting jack is provided with pressure transducer.Lifting jack and pressure transducer are positioned at reaction frame, and pressure transducer connects digital display instrument.
Pullout tests: expansion bolt carries out lifting jack hierarchical loading according to often pulling up 2mm distortion, and every grade of load continues 10 minutes, carries out the security inspection of structural member simultaneously.
1. often load one-level to carry out lifting jack and pull up power monitoring, and record lifting jack numerical value.
2. when lifting jack pull up power have obviously decline time, namely think that expansion bolt reaches the ability to work limit, now terminate load.
3. detaching device.
4. finishing analysis is carried out to data, show whether expansion bolt distortion and withdrawal resistance meet job requirement.
Claims (3)
1. one kind is detected the easy device of withdrawal resistance, it is characterized in that: comprise reaction frame, the bottom of reaction frame is provided with for fixing expansion bolt, the top of expansion bolt is provided with dial gauge, reaction frame is forward and backward is respectively provided with a bearing, between two bearings, erection has bearing beam, and bearing beam is placed lifting jack and pressure transducer, lifting jack and pressure transducer are positioned at reaction frame; Described reaction frame is the quadra be welded by shaped steel; Described bearing beam is provided with 50T lifting jack, and 50T lifting jack is provided with pressure transducer.
2. the easy device of detection withdrawal resistance according to claim 1, is characterized in that: described expansion bolt is for connecting reaction frame and concrete.
3. the easy device of detection withdrawal resistance according to claim 1, is characterized in that: described bearing beam is made by channel-section steel.
