Description

A tool for measuring floor thickness

technical field

The utility model relates to the technical field of measuring instruments, in particular to a floor thickness measuring tool.

Background technique

In the process of quality acceptance of new projects and inspection and evaluation of existing buildings, in order to ensure that the floor slab construction meets the design and specification requirements and provide data for later evaluation, it is necessary to select a certain number of measuring points to measure the thickness of the floor slab.

In the process of floor thickness measurement, when conventional existing floor thickness measurement instruments are used, after the measurement hole is opened at the measurement point, a flat plate needs to be set directly below the measurement hole to withstand it, and then the measuring ruler is inserted into the measurement hole. The data of the floor thickness at this point can be measured.

The main disadvantage of such conventional measuring tools and measuring methods is that at least two people must cooperate, and climbing equipment is required to temporarily fix the plate at the measuring point to complete the measuring work. Such conventional methods are labor-intensive and time-consuming.

Utility model content

The purpose of this utility model is to provide a floor thickness measuring tool, which mainly solves the technical problems existing in the above-mentioned prior art. The utility model has an outrigger that can be expanded and retracted, and it is convenient to realize the single-person measurement of the floor thickness. , save labor and time.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A tool for measuring floor thickness, characterized in that it includes a main scale with scales, a sub scale, a gear, an outrigger, a sliding rod and a blocking block; wherein: the sub scale is sleeved on the main scale, and the main scale The bottom is connected with a rotatable gear, and a sliding rod is sleeved inside the main ruler. The sliding rod has teeth meshed with the gear. The gear is also connected with an outrigger. The stop block with an angle of more than 90° with the main ruler.

The floor thickness measuring tool is characterized in that: the main ruler has a groove for the outrigger to be put into it after being retracted.

The floor thickness measuring tool is characterized in that: the auxiliary ruler is provided with fasteners for the auxiliary ruler to be locked on the main ruler.

The floor thickness measuring tool is characterized in that: the length of the outrigger is 100-150 mm.

The utility model has the advantages that: the utility model has an outrigger that can be unfolded and retracted, which conveniently realizes the single-person measurement of the thickness of the floor slab, and saves labor and time.

Detailed ways

Please refer to Fig. 1-3, the utility model discloses a floor thickness measuring tool. As shown in the figure: it includes a main ruler 5 with a scale, an auxiliary ruler 6, a gear 2, an outrigger 3, a sliding rod 4 and a blocking block 1. Wherein: the auxiliary ruler 6 is sleeved on the main ruler 5, and can slide up and down along the main ruler 5; The rod 4 has a tooth portion meshed with the gear 2, the gear 2 is also connected with an outrigger 3, and the bottom of the main scale 5 is also connected with a stop block 1 that limits the angle between the outrigger 3 and the main scale to exceed 90° after being expanded. . The outrigger 3 is connected with the sliding rod 4 through the gear 2, and the sliding rod 4 slides up and down to drive the gear 2 to rotate, and indirectly drives the outrigger 3 to expand and retract. The blocking block 1 is used to control the maximum angle of 90° between the outrigger 3 and the main scale after being deployed.

The main scale 5 has a slot 8 for the outrigger 3 to be taken in after being retracted.

The auxiliary ruler 6 is provided with a fastener 7 for the auxiliary ruler 6 to be locked on the main ruler 5, so that the auxiliary ruler 6 can be locked on the main ruler 5 to facilitate reading. The length of the outrigger 3 is 100-150mm.

The operation process of the floor thickness measuring tool of the utility model is as follows: firstly drill a measuring hole at the measuring point, and in the initial state, the outrigger 3 of the measuring tool is retracted into the groove 8, and the bottom of the main ruler 5 is inserted into the measuring hole, and the depth to be penetrated is reached. After exceeding the stowed height of the outrigger 3, pull up the sliding rod 4, the teeth of the sliding rod 4 drive the gear 2 to rotate clockwise, and further expand the outrigger 3, and when the outrigger 3 is deployed to 90°, it is blocked 1 block, can not continue to expand, at this time is the vertical state; press down the sub-foot 6 to the floor surface, you can read the measured value of the floor thickness. After the reading of the measuring point is completed, press down the sliding rod 4, the tooth portion of the sliding rod 4 drives the gear 2 to rotate counterclockwise, and then the outrigger 3 is retracted into the groove 8, and the measuring tool is lifted to complete the measurement of the floor thickness at one point. .

The description and application of the present invention here are illustrative, and are not intended to limit the scope of the present invention to the above-mentioned embodiments. Variations and changes to the embodiments disclosed herein are possible, and substitutions and equivalents for various components of the embodiments are known to those of ordinary skill in the art.
