Abstract

The utility model discloses a concrete floor thickness measurement device. The concrete floor thickness measurement device comprises a measuring rod, a blocking rod, a rotating shaft, a handle and a long rope. The measuring rod is connected with the blocking rod through the rotating shaft, the upper wall of the blocking rod is provided with a cavity, graduation lines are engraved in the surface of the measuring rod, the end portion of the blocking rod is connected with the handle, and the long rope is tied to the handle. The measuring method comprises the following steps of stretching the furled measuring rod and the furled blocking rod into a small hole in the floor, unfolding the blocking rod under the floor automatically, holding and lifting the upper portion of the measuring rod and the free end of the long rope over the floor by a measurement person to make the blocking rod cling to the floor horizontally, reading data on the graduation line, of the measuring rod, aligned to the upper surface of the floor, and recording the data, lowering the measuring rod, lifting the free end of the long rope, and taking out the furled blocking rod and the furled measuring rod from the hole. The utility model aims at providing a cheap, convenient, fast, efficient and simple concrete floor thickness measurement device.

Description

The device that a kind of thickness of concrete floor is measured

Technical field

The utility model relates to a kind of measurement mechanism, relates in particular to the device that a kind of thickness of concrete floor is measured.

Background technology

Before concrete main body structure acceptance or before newly constructed house payment user use, in order to detect the thickness of concrete floor, whether reach designing requirement, generally take two kinds of detection methods, a kind of method is to adopt special-purpose electronic measuring instrument to carry out Non-Destructive Testing at concrete floor upper surface, although this instrument can detect slab thickness, but expensive, be not suitable for common house user; Another kind method is by concrete floor is holed, during measurement, one people props up eyelet by template below floor, another people inserts in the hole with bar dowel above floor, makes the lower end of reinforcing bar arrive at the template face of floor below, and then is close to the setting-out on reinforcing bar of floor upper surface, finally take out reinforcing bar, with tape measure, measure this line to the length of reinforcing bar lower end, this length is the thickness of floor, and the method needs two people to closely cooperate, bring very large inconvenience to floor surveying work, and efficiency is lower.

Utility model content

In order to overcome above-mentioned defect, the technical problems to be solved in the utility model is: the device that provides a kind of thickness of concrete floor to measure, it is not only cheap, being applicable to ordinary populace uses, and whole measuring process is quick, efficient, only needs a people just can complete the work of measuring thickness of concrete floor.

The utility model is that the technical scheme that solves the problems of the technologies described above employing is: the measurement mechanism of this thickness of concrete floor is comprised of gauge rod, pin, rotating shaft, handle and long rope, between gauge rod and pin, with rotating shaft, connects; On pin roof, have a corresponding cavity of shape, width, thickness and gauge rod, but the length that is shorter in length than gauge rod of cavity, while not carrying out surveying work, can be placed in cavity with the corresponding gauge rod body of rod of cavity length; On the body of rod surface of gauge rod, be carved with scale mark; The end of pin is connected with handle, and on handle, being has long rope.

The measuring method of a kind of thickness of concrete floor of the present utility model, comprises the following steps:

Step 1, stretches into the pin of rounding state and gauge rod in the aperture having bored on floor, makes pin pass completely through aperture;

Step 2, pin is Automatic-expanding below floor, and survey crew is held the free end of gauge rod top and long rope and is upwards carried above floor, makes pin level be close to floor;

Step 3, reads the data on scale mark equal with floor upper surface on gauge rod, and records, and these data are the thickness of concrete floor of measuring;

Step 4, reduces gauge rod, and the free end of long rope is upwards carried, and makes pin become from horizontality pin and the gauge rod that takes out gathering plumbness ，Cong hole.

The beneficial effects of the utility model are: 1, the device due to the measurement of thickness of concrete floor of the present utility model is mainly comprised of gauge rod and pin, and manufacturing cost is little, therefore cheap, are applicable to ordinary populace and use; 2, in specific operation process, only need a people just can complete the work of measuring thickness of concrete floor, whole measuring process is quick, efficient.

In figure: 1, gauge rod, 2, pin, 3, rotating shaft, 4, cavity, 5, scale mark, 6, handle, 7, long rope.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, the measurement mechanism of a kind of thickness of concrete floor of the present utility model, is comprised of gauge rod, pin, rotating shaft, handle and long rope, between gauge rod 1 and pin 2, with rotating shaft 3, connects; On pin 2 roofs, have a shape, width, thickness and the corresponding cavity 4 of gauge rod 1, but the length that is shorter in length than gauge rod 1 of cavity 4, while not carrying out surveying work, can be placed in cavity 4 with corresponding gauge rod 1 shank portion of cavity 4 length; On the body of rod surface of gauge rod 1, be carved with scale mark 5; The end of pin 2 is connected with handle 6, and on handle 6, being has long rope 7.

The measuring method of a kind of thickness of concrete floor of the present utility model, specifically comprises the following steps:

Step 1, stretches into the pin of rounding state 2 and gauge rod 1 in the aperture having bored on floor, makes pin 2 pass completely through aperture;

Step 2, pin 2 Automatic-expanding below floor, survey crew is held the free end of gauge rod 1 top and long rope 7 and is upwards carried above floor, makes pin 2 levels be close to floor;

Step 3, reads the data on scale mark equal with floor upper surface on gauge rod 15, and records, and these data are the thickness of concrete floor of measuring;

Those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, to the variation of the above embodiment, modification, all will drop within the scope of claims of the present utility model.
