Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a floor thickness gauge for construction engineering. Background Art

[0002] A floor thickness gauge is an instrument used to measure the thickness of concrete structures such as floor slabs, shear walls, beams, and columns, as well as other non-ferromagnetic materials. Based on the kinematics and dynamics of electromagnetic waves and electronic technology, it primarily consists of signal transmission, reception, signal processing, and display units. When the probe receives the electromagnetic signal from the transmitter, the signal processing unit analyzes the kinematic characteristics of the electromagnetic wave and automatically calculates the distance from the transmitter to the receiver. This distance represents the thickness of the test plate. The thickness value is then displayed, stored, and transmitted.

[0003] In the prior art, the echo detector of the floor thickness gauge is mostly connected to the top of the telescopic rod through a thread. After long-term use, the thread may slip, resulting in inaccurate measurement results and reducing the practicality of the device. Utility Model Content

[0021] 1. In the present invention, two workers are required to measure the thickness of the floor slab. One of them holds the main body on the roof and presses it against the top surface of the floor slab, and the other holds the telescopic rod connected to the echometer on the downstairs and presses it against the bottom surface of the floor slab. When installing the echometer, the handle is used to press the sliding rod toward the inside of the telescopic rod, so that the slider compresses the reset spring, and the U-shaped frame is driven by the connecting rod to drive the two clamping rods to drive the clamps to be relatively separated. After the connecting rod is inserted into the top of the telescopic rod, the handle is released. The two clamping rods drive the clamps to clamp the connecting rod under the rebound of the reset spring, thereby achieving the effect of quickly installing and disassembling the echometer through the connecting mechanism, avoiding the occurrence of inaccurate measurement results due to slippage of the threaded connection, and improving the practicality of the device.

The limit block transmits the information to the contact spring so that the reading record appears on the display screen. This achieves the effect of quickly detecting the flatness of the floor through the flatness detection mechanism, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
