Description
Technical field
The utility model belongs to technical field of building construction, more particularly to a kind of concrete slab thickness detector.
Background technology
Cast-in-situ floor, wall equal thickness situation are to evaluate the important indicator of building safety performance, increasingly by country
The attention of relevant department, quality surveillances at different levels detect unit to floor, and the detection technique of thickness of wall body is extremely paid close attention to.Conventional cast-in-place
And the detection of precast rc slab thickness uses dedicated instrument, when detection, transmitting probe is placed in soffit and is arranged in advance
Measuring point on, probe top surface be close to soffit；Receiving transducer is located at floor top surface, and at this moment receiving transducer is located on transmitting probe
Just within the scope of certain, instrument test key is pressed, if numerical value does not occur in thickness display location on screen, illustrates that receiving transducer is visited away from transmitting
Head top position is farther out.Mobile probe is scanned, when showing thickness value in moving process, on screen（<350mm）Illustrate to visit
Head has been located in the range of transmitting probe top diameter 50cm, and probe is close to floor top surface, is controlling slowly mobile probe, is making
Thickness value is gradually reduced on screen, the position until finding minimum value, then the position is placed exactly in right over transmitting probe, display
Thickness value be the measuring point slab thickness.Existing measuring instrument is complicated for operation, and entire detection process efficiency is low.
Invention content
The purpose of this utility model is to provide for a kind of easy to operate, can promote the concrete plate thickness inspection of detection efficiency
Survey device.
For this purpose, the technical solution of the utility model is：A kind of concrete slab thickness detector, it is characterised in that：Including outer
Pipe, adjustable pipe and inner tube, outer tube, adjustable pipe are hollow-core construction；The outer tube is equipped with graduation mark, and adjustable pipe is placed in outer tube
Interior, the outer wall of adjustable pipe is equipped with the loose slot being axially arranged；Said inner tube is placed in adjustable pipe, and passes through loose slot and outer tube
It is fixed as one；Said inner tube bottom end is rotatablely installed the baseline rod of two strips, and adjustable pipe bottom end is equipped with on baseline rod
Hanging hole, adjustable pipe are connected with baseline rod by connecting rod of the both ends with hook；The adjustable pipe drives base by connecting rod
Quasi- bar rotation, two baseline rods, which exist, to be launched into "-" type and is shrunk to inverse Ba type two states.
Preferably, when the adjustable pipe is displaced downwardly to minimum point, two baseline rods are launched into horizontal "-" type structure, and one
The horizontal distance at font both ends is more than the diameter of outer tube；When moving to peak in the adjustable pipe, two baseline rods are shrunk to down
Splayed configuration structure, and the horizontal distance at splayed configuration structure both ends is less than the diameter of outer tube.
When utility model works, trepanning is first carried out on concrete slab to be measured, and entire measuring device is then inserted into hole
In hole, at this point, two baseline rods are shrunk to inverse Ba type structure, baseline rod is allow to pass through hole, be in concrete slab bottom；
Then adjustable pipe is moved down, connecting rod pushes baseline rod so that two baseline rods are flared to horizontal "-" type；Then, outer tube is gently carried,
So that baseline rod is close to concrete slab bottom, reads the reading for being located at outer tube high scale line at the top of concrete slab, confirm plate thickness；It measures
After, outer tube is lowerd, makes baseline rod disengaging plate bottom, redrawing adjustable pipe that horizontal baseline rod be made to pack up in inverse Ba type
Umbrella, you can extract detection device, to next piece of board under test circulate operation.
The utility model is suitable for conventional cast-in-place and precast rc slab thickness detects, and single unit system is small and exquisite, convenient for taking
Band；It is easy to operate, it is reusable, detection time is saved, detection efficiency is promoted, improves accuracy of detection.

In figure label for：Outer tube 1, adjustable pipe 2, loose slot 21, inner tube 3, baseline rod 4, connecting rod 5, concrete slab 6.
Specific implementation mode
Referring to attached drawing.The present embodiment includes outer tube 1, adjustable pipe 2 and inner tube 3, and outer tube 1, adjustable pipe 2 are hollow-core construction；
The outer tube 1 is equipped with graduation mark, and adjustable pipe 2 is placed in outer tube, and the outer wall of adjustable pipe is equipped with the loose slot 21 being axially arranged,
Adjustable pipe upper and lower ends are equipped with loose slot；Said inner tube 3 is placed in adjustable pipe 2, and is fixed as one by loose slot and outer tube 1
Body, inner tube 3 are fixed with 1 phase of outer tube, and adjustable pipe 2 can be moved up and down with respect to inner and outer pipe, and loose slot plays position-limiting action；It is described
3 bottom end of inner tube is rotatablely installed the baseline rod 4 of two strips, is equipped with hanging hole on adjustable pipe bottom end and baseline rod, adjustable pipe 2 with
Baseline rod 4 is connected by connecting rod 5 of the both ends with hook；The adjustable pipe 2 drives baseline rod 4 to rotate by connecting rod 5,
