A floor slab thickness measuring tool and its measuring method

Abstract

The invention discloses a floor thickness measuring tool, which comprises a measuring part having scale marks, a clamping and fixation part connected to the bottom end of the measuring part, and a lifting and pulling part inserted in the measuring part. The clamping and fixation part is separated into a front section and a back section by a joint point, wherein the front section is larger than the back section in weight; the bottom end of the lifting and pulling part is provided with a connection rod; and one end of the connection rod is in rotary connection with the lifting and pulling part, and the other end of the connection rod is connected with a slide groove in the side surface of the front section of the clamping and fixation part. The connecting rod type active link device capable of folding and unfolding is adopted, so that the measuring tool is allowed to be closed under a non-working state, and opened under a working state; when the measuring tool is utilized to carry out pre-embedding and measurement, floor thickness can be measured losslessly, the data is accurate, and the floor can be repaired easily; and through the tool, labor force is saved, working efficiency is improved, damage to the plate is prevented, and the case of water leakage basically does not occur.

Description

technical field [0001] The invention relates to a checking tool used in construction engineering, in particular to a plate thickness measuring tool. Background technique [0002] After pouring the floor slab, it is necessary to test the thickness of the floor slab. At present, the commonly used measurement methods include the following: 1. Instrument detection, 2. Concrete coring, 3. Electric drill drilling to measure the thickness of the floor slab. [0003] When the instrument is used, it is necessary to equip several personnel on the board and below the board, use the walkie-talkie to communicate, and then take a certain point on the fixed board, and the thickness of the board can be measured only after the transmitter and receiver of the instrument are aligned. There is damage, but the measurement is troublesome, time-consuming and labor-intensive, and the data error is relatively large. Concrete coring is used to measure the thickness of the poured floor slab. Although...

[0003] When the instrument is used, it is necessary to equip several personnel on the board and below the board, use the walkie-talkie to communicate, and then take a certain point on the fixed board, and the thickness of the board can be measured only after the transmitter and receiver of the instrument are aligned. There is damage, but the measurement is troublesome, time-consuming and labor-intensive, and the data error is also large

Carry out concrete coring to measure the slab thickness of the poured floor slab. Although the data is accurate and intuitive, the coring machine needs to connect the wires, which creates a safety hazard and causes great damage to the floor slab. It will be troublesome to repair in the future and may easily lead to water leakage.

Use an electric drill to measure the thickness of the plate after drilling. When drilling, it is necessary to avoid steel bars. It is often difficult to implement. It takes multiple drillings to find a suitable hole. Often the diameter of the drilling is irregular and not vertical. When measuring, multiple people cooperate. , the damage to the board is greater, and it is difficult to repair
