Abstract
An axial force detector of a lag bolt is composed of a fixed support base, an intermediate connection piece, a tension sensor and a force value indicator. One end of the tension sensor is connected with the intermediate connection piece through screws, and the other end of the tension sensor is connected with a baseboard of the fixed support through a sliding rail structure. The axial force detector has the advantages of being simple in structure, convenient to operate, accurate in data detection, and capable of detecting the axial force of both stay bolt pairs and lag bolt pairs.
Description
Technical field
The utility model belongs to testing tool, relates to bolt shaft power detector, especially can detect the axle power of lag bolt pair.
Background technology
High-strength bolt, must detect bolt countershaft power according to state compulsory standard GB50205-2001 " structural steelwork acceptance specification " relevant requirements as the main link of steel building.At present, known bolt shaft power detector is comprised of axle power application system, pressure transducer, secondary instrument display system.The restriction of sensor and the axle power application system structure of being stressed, known bolt shaft power detector only can detect the axle power of the above bolt pair of length 〉=50mm, use length can't detect as the axle power of lag bolt pair between 30mm～50mm for steel building, restricted the steel building industry development.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly not only can detect thru-bolt countershaft power, and can detect the axle power that length is the lag bolt pair between 30mm～50mm.。
For solving the problems of the technologies described above, the new basic conception of this practicality is: known bolt shaft power detection method is exerted pressure by axle power is improved to the stretching of axle power.
As the technical scheme that realizes the utility model basic conception, it is by hold-down support, and intermediate connector, pulling force sensor, power value index gauge form.Pulling force sensor one end connects with intermediate connector with screw, and the other end adopts the bottom plate connecting of rail structure and hold-down support.
The beneficial effects of the utility model are: have simple in structurely, easy to operate, it is accurate to detect data, not only can detect the axle power of thru-bolt pair, and can detect the axle power of lag bolt pair.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, be lag bolt axle power detector structural representation of the present utility model.
1. bolt pairs among the figure, 2. hold-down support, 3. intermediate connector, 4. pulling force sensor, 5. power value index gauge.
Specific embodiments
Consult Fig. 1, hold-down support 2 usefulness steel plates are made, the panel middle part perforate of hold-down support 2.The top of intermediate connector 3 is processed with slot and groove, and the bottom is processed with screw.Pulling force sensor 4 one ends are connected with middle with screw, and the other end connects with the base plate employing rail structure of hold-down support 2, make the stressed axis of the stressed axis of pulling force sensor 4 and bolt pair 1 on the same straight line.Power value index gauge 5 usefulness wires connect with pulling force sensor 4.During measurement, to the nut of bolt pair 1 moment of torsion of exerting pressure, the axial tension that bolt is subjected to is passed to pulling force sensor 4 through intermediate connector 3 with dial torque wrench, shows bolt pairs 1 suffered axle power by power value index gauge 5.
Claims (2)
1. lag bolt axle power detector, it is characterized in that: it is comprised of hold-down support (2), intermediate connector (3), pulling force sensor (4), power value index gauge (5).
2. lag bolt axle power detector according to claim 1 is characterized in that: pulling force sensor (4) one ends connect with intermediate connector (3) with screw, the bottom plate connecting of other end employing rail structure and hold-down support (2).
