Embodiment 1

[0046] Embodiment one: if image 3 The sleeve 1 shown has defects in its internal grouting. Using the detection method of the present invention to image 3 The specific process of detecting grouting defects inside the sleeve 1 shown is as follows:

[0047] Step 1. Provide the detection device, requiring the probe 7 to have a diameter of 3.5 mm; the probe 7 is equipped with a visible light lens, using high-brightness LED lighting technology, the depth of field of the lens is continuously adjustable from 2 to 100 mm, and the wide angle is 120°; two sets of laser transmitters 10 The emitted laser beam is parallel; and the diameter of the laser beam is 0.10mm, and the distance d is 1.0mm;

[0048] Step 2. Arrange the detection holes as required: you can use a drill with a drill bit diameter of 4.5mm to drill holes, or use a plastic conduit to directly reserve detection holes during grouting;

[0049] Step 3. Set the detection position of the probe 7 in the detection hole, and ...

Embodiment 2

[0054] Embodiment two: if Figure 4 Shown is a schematic diagram of the inspection of sleeve 1 with no defects in internal grouting. Steps 1 to 4 in this embodiment are the same as in Embodiment 1. In step 5, the probe 7 extends into the detection hole to reach the detection position, and the captured image is a uniform and dense structure, such as Figure 5 As shown, it is considered that the sleeve 1 is full of grouting and has no defects, and the defect size is 0.

Abstract

The invention discloses a laser scaleplate endoscopic sleeve grouting defect detecting device, comprising an endoscope, two groups of laser emitters, an insertion catheter and a controller, wherein the endoscope is movably installed at an end head of the insertion catheter, and a lens of the endoscope can rotate around a center line thereof; the endoscope is connected with the controller through an optical fiber core conduction line, and the controller is provided with a display screen; the two groups of laser emitters are installed at a front end of the endoscope side by side and the two groups of laser emitters can rotate with the endoscope; the laser emitters are connected with the controller through transmission conducting wires; the optical fiber core conduction line and the transmission conducting wires are all arranged in the insertion catheter, and one end of the insertion catheter stretches into a detection hole of a grouting sleeve with the endoscope and the laser emitters; and the detecting device is further provided with a tilt angle test system disposed at the outside the detection hole, the tilt angle test system comprises an auxiliary probe that rotates synchronously with the probe of the endoscope, and a dynamic tilt angle sensor is fixed to a front end of the auxiliary probe. The invention further discloses a sleeve grouting defect detecting method. The laser scaleplate endoscopic sleeve grouting defect detecting device disclosed by the invention has the beneficial effects of convenient operation, intuitive and accurate detection result, no damage to detected objects, and relatively high economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of quality detection of node connectors in prefabricated buildings, in particular to a laser scale endoscopic sleeve grouting defect detection device and method. Background technique [0002] In recent years, due to the rapid development of the economy, rising labor costs, people's awareness of energy conservation and emission reduction has continued to increase, and prefabricated buildings have gradually warmed up and developed rapidly. According to the statistics of the Ministry of Housing and Urban-Rural Development, in 2015, the area of ​​new prefabricated buildings nationwide was 72.6 million m2 2 , 114 million m in 2016 2 , 140 million m in 2017 2 , most of which are prefabricated monolithic concrete buildings, and the problem of insufficient grouting sleeves for prefabricated concrete structure connections has gradually been exposed, which has attracted widespread attention. Rebar sleeve grouting c...
