Technical field

The present invention relates to field concrete NDT apparatus fields, and in particular to a kind of concrete strength inspection device and its inspection Survey method.

Background technique

With the quickening of Urbanization in China, the requirement to concrete strength is higher and higher.Concrete is due to its intensity Height, plasticity are good, at low cost, are current most widely used construction materials.The quality height of concrete directly affects reinforcing bar and mixes mud The entire construction building of soil structure, if any the security of the lives and property that will injure the masses accidentally.The quality control of concrete thus It is the most important thing in construction.Concrete strength detecting method generally comprises native rebound method, ultrasonic method, ultrasonic rebound synthesis etc., But existing detection method and equipment is using complex, operates relatively complicated, staff needs strictly to operate with, inspection Degree of testing the speed is slow, low efficiency.In the work progress in construction project, the concrete used has to that there are concrete examinations Block, and be sent to relevant detection department and test test to the intensity of concrete test block, this just considerably increases strong concrete The detection difficulty of degree.

Summary of the invention

In view of the above problems, the invention proposes a kind of concrete strength inspection device and its detection method, with Traditional concrete NDT device and method are compared, and have obvious quick, high efficiency, while easy to operate, detection of the invention As a result it is convenient for visual record, repetition is facilitated to detect, also increases the accuracy of concrete strength inspection result.

In order to achieve the above purpose, the following technical solution is employed by the present invention:

Preferably, the detection case side is equipped with through slot, and described link block one end is equipped with the finger that activity runs through the through slot Needle, the detection box outer wall positioned at the through slot side are equipped with graduated scale.

Preferably, the link block is equipped with threaded rod, and the counterweight activity is on the threaded rod, the threaded rod Screw thread is socketed with stop nut.

Preferably, described rotating roller one end is coaxially fixed with turntable, and the turntable is equipped with crank, sets on the turntable Have through limit bolt is equipped with, limit bolt end activity is plugged on the jack of the mounting rack side wall.

Preferably, the both ends of the support plate upper surface are equipped with universal level bulb.

Preferably, the detection case front side bottom is equipped with transparent observing window.

Preferably, two sides are equipped with lid door at the top of the detection case.

Preferably, the mounting base bottom installation is equipped with rubber ring.

A kind of detection method of concrete strength inspection device, comprising the following steps:

S1: concrete test block to be detected is placed on the supporting plate, by the rotating disk on rotary mounting seat, passes through spiral shell Bar drives support plate toward moving up, so that concrete test block to be detected is tightly attached on the rubber ring of mounting base bottom, passes through observation Universal level bulb in support plate, it is ensured that support plate is horizontal；

S2: being drawn high pressing plate while traction rope is wound so that rotating roller rotates by shake handle, open lid door, Allow counterweight to fill the threaded rod on link block, is plugged on mounting rack side by the way that limit bolt is passed through turntable activity Wall limits rotating roller rotation, then counterweight is filled on the threaded rod on link block, is socketed in screw thread by stop nut screw thread Bar fixes counterweight, guarantees that the counterweight weight at pressing plate both ends is consistent；

S3: hand-held crank simultaneously takes out limit bolt, by shaking crank, controls pressing plate floor detection pressure head apart to be checked The height of the concrete test block of survey, record pointer are directed toward the height number on graduated scale；

S4: crank is unclamped, so that pressing plate free-falling, the detection ram strikes concrete test block to be detected of pressing plate bottom Upper surface, repetition by holding crank, winds traction rope by rotating roller when hitting to concrete test block to be detected Pressing plate is drawn high, is corresponded to after pressing plate is pulled up to identical height by scale position again by pointer, is discharged crank, detect pressure head Finally hit the upper surface of concrete test block to be detected again, that is, complete detection operation, by the observation of transparent observing window to The breakage on the concrete test block surface of detection records data.

Due to using above-mentioned technical solution, the beneficial effects of the present invention are: the present invention can be obtained by manual operation To the testing result of concrete, the situation after concrete surface is knocked can be directly observed, can be incited somebody to action by hand crank Pressing plate is drawn high, and according to different coagulation soil characteristics, is freely increased counterweight according to situation or is adjusted the height of pressing plate, collect to coagulation The detection data that soil is hit in various degree, and detect quickly, easy to operate, testing result is intuitively obvious；The present invention detects coagulation Native intensity device and method have obvious quick, high efficiency, while this compared with traditional concrete NDT device and method That invents is easy to operate, and testing result is convenient for visual record, and repetition is facilitated to detect, and also increases the standard of concrete strength inspection result True property, is with a wide range of applications.
