Description
Technical field
The utility model relates to a kind of concrete working device, especially relates to a kind of sprayed concrete early strength rapid determination device.
Background technology
In underground engineering construction process, judge that the early strength development of sprayed concrete is extremely important for early stage supporting.Current sprayed concrete strength generally adopts spray large plate core drilling method and on-the-spot core drilling method, but core drilling method only has concrete strength to reach more than 10MPa could be suitable for, and is not suitable for early age strength of concrete detection.Therefore, in Construction practices, a kind of method measuring sprayed concrete early strength is needed.
Utility model content
The utility model provides a kind of sprayed concrete early strength rapid determination device, and this device utilizes the linear relationship of device penetration concrete resistance and concrete strength to measure concrete strength.Its technical scheme is as described below:
A kind of sprayed concrete early strength rapid determination device, comprise chaining pin, transmission rod, spring device for measuring force, display unit, described transmission rod arranged outside has shell, described shell is provided with handle, described chaining pin is connected with described transmission rod, described transmission rod is connected with spring device for measuring force, and described spring device for measuring force is connected with display unit.Described display unit can show the measured value of described spring device for measuring force.
Described chaining pin top is provided with spacing ring.
The diameter of described chaining pin is 3mm, and the bevel angle of end is 60 °, and the length of needle body part is 15mm.Described chaining pin can dismounting and change.
The material of described chaining pin and transmission rod is steel, and the material of described shell and handle is rigid plastic.
Described transmission rod is connected with described spring device for measuring force, and described chaining pin diameter is 3mm, and end tapered angle is 60 °, and the length of needle body part is 15mm.
The material of described chaining pin and transmission rod is steel, and the material of described shell and handle is rigid plastic.
This sprayed concrete early strength rapid determination device structure is simple, easy to operate, can Fast Measurement sprayed concrete early strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of described sprayed concrete early strength rapid determination device;
Fig. 2 is the part-structure enlarged diagram of Fig. 1;
1-chaining pin in figure; 2-spacing ring; 3-shell; 4-handle; 5-display unit; 6-transmission rod; 7-spring device for measuring force.
Embodiment
This device comprises chaining pin 1, shell 3, transmission rod 6, spring device for measuring force 7, display unit 5 and handle 4, and described chaining pin 1 top is provided with spacing ring 2, and is connected with described transmission rod 6.Described transmission rod 6 is connected with spring device for measuring force 7, and described display unit 5 can show the measured value of described spring device for measuring force 7.
Described chaining pin 1 diameter is 3mm, and end tapered angle A is 60 °, and the length of needle body part is 15mm.Described chaining pin 1 can dismounting and change.The material of described chaining pin 1 and transmission rod 6 is steel, and the material of described shell 3 and handle 4 is rigid plastic.
After the purpose of this utility model is achieved in that sprayed concrete completes certain length of time at the scene, selection intensity test point, thrust unit handle 4, chaining pin 1 is passed through and vertically enters concrete surface until spacing ring 2, the stressed of chaining pin 1 is passed to spring device for measuring force by transmission rod 6, and shows this force value on display unit 5.Linear relationship according to pre-determined penetration concrete resistance and concrete strength just conveniently can infer the concrete early strength of this point.For avoiding operate miss, can select to operate for 10 times, using the measured value of the mean value after rejecting overproof measured value as this point.
