Abstract
Disclosed is a simple device for testing a pulling resistance force. The simple device includes a counterforce frame, the bottom part of which is provided with an expansion bolt used for fixing. The top end of the expansion bolt is provided with an indicating gauge. The counterforce frame is provided with a support at the front and back respectively. A sleeper beam is arranged between the two supports. A jack and a pressure sensor are arranged on the sleeper beam. The jack and the pressure sensor are located in the counterforce frame. The simple device for testing the pulling resistance force is simple in structure and convenient to use. Materials can be used locally and purchase of a large quantity of testing devices is not needed so that testing is easy to implement. The simple device is not only capable of testing force values which can be tested by instruments in the market, but also capable of enabling the maximum pulling resistance force and corresponding displacement of an anchoring part during work to be observed through a force-displacement curve chart so that whether work demands are met is judged.
Description
Technical field
The utility model belongs to building field utility appliance, relates in particular to a kind of pick-up unit.
Background technology
There is in the market the professional instrument that detects withdrawal resistance, withdrawal resistance for detection of anchoring pieces such as various anchor poles, anchor cable, reinforcing bar, expansion bolts, can measure the ultimate tensile strength (UTS) of anchoring piece, but in practical application, only detecting, understand ultimate tensile strength (UTS) is nowhere near, sometimes need to detect anchoring piece other conditions when work and whether meet job requirement, as displacement etc.Separately, the professional instrument on market need be purchased specially, buying trouble, and practicality is low.
Utility model content
Technical problem to be solved in the utility model is for the deficiency in background technology, and a kind of easy device that detects withdrawal resistance is provided.
In order to address the above problem by the following technical solutions: a kind of easy device that detects 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, set up bearing beam, placed lifting jack and pressure transducer on bearing beam, lifting jack and pressure transducer are positioned at reaction frame.
Described expansion bolt is used for connecting reaction frame and concrete.
Described reaction frame is the quadra being 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.
The utility model is simple in structure, 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 measuring the power numerical value that market instrument can measure, can also measure displacement, and withdrawal resistance and the corresponding displacement of maximum while going out anchoring piece work by force-displacement curve figure observable, thereby judge whether to meet job requirement.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
Embodiment
As shown in Figure 1, 2, a kind of easy device that detects withdrawal resistance, comprises that the quadra being welded by shaped steel is as reaction frame, and the bottom of reaction frame is provided with expansion bolt, and expansion bolt is used 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, between two bearings, sets up the bearing beam being made by channel-section steel, places 50T lifting jack on bearing beam, and 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.
Resistance to plucking test: 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. every loading one-level is carried out lifting jack and is pulled up power monitoring, and records lifting jack numerical value.
2. when lifting jack pulls up power and has obvious decline, think that expansion bolt reaches the ability to work limit, now finish to load.
3. detaching device.
4. data are carried out to finishing analysis, show whether expansion bolt distortion and withdrawal resistance meet job requirement.
Claims (5)
