Technical Field

The invention relates to the technical field of building construction measuring tools, in particular to a plate thickness measurer.

Background

In civil engineering and construction, concrete pouring is a very common construction method, and in the concrete pouring, concrete is poured into a mold until the concrete is plasticized, in the civil engineering and construction, materials such as concrete are transferred into the mold to be formed into a predetermined shape, physical properties of the concrete need to be measured after the concrete is poured, and the thickness of the concrete is one of parameters that determine the quality of the civil engineering and construction, and therefore needs to be measured.

The existing concrete floor measuring modes are divided into two types: firstly, adopt the instrument disect insertion concrete that has the scale to measure it in the preformed hole, secondly directly stretch into the tape measure and measure, these two kinds of measurement mode all exist as follows not enoughly: 1. the bottom of the measuring tool cannot be kept flush with the other side surface of the floor slab, so that an error exists in measurement; 2. the vertical insertion of the measuring tool into the concrete cannot be guaranteed, and the deviation is easily generated in the insertion process, so that the error of the measuring parameter is large; 3. due to the low height of the concrete, direct reading of the measurement readings is inconvenient.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a plate thickness measurer which can effectively ensure that the measurer is horizontally attached to two side surfaces of a floor slab and ensures the measurement precision, and the device has a simple structure and is convenient to measure.

A plate thickness measurer comprises a connecting cylinder, at least two supporting rods, a measuring plate, a measuring rod and a reset spring, wherein the connecting cylinder is arranged at one end of the measuring rod, the supporting rods are hinged with one end, far away from the measuring rod, of the connecting cylinder, the measuring plate is sleeved outside the measuring rod in a sliding mode, one end of a connecting rope is fixed on the measuring plate, the other end of the connecting rope is arranged in the middle of the supporting rod, and the middle of the supporting rod is connected with one end, close to the measuring rod, of the connecting cylinder through the reset spring;

a hinged pipe is arranged at one end of the connecting cylinder, which is far away from the measuring rod, a containing groove for containing the supporting rod is arranged in the middle of the hinged pipe, a hinged rod is arranged at the end part of the supporting rod, and the connecting cylinder and the supporting rod are connected with the hinged rod through the hinged pipe; the inner wall of the hinged pipe is provided with a semicircular limiting groove, and the hinged rod is provided with a limiting block in sliding fit with the limiting groove;

the measuring rod is provided with scale marks, and in an initial state, the surface of the measuring plate close to the connecting cylinder and the zero scale marks are located on the same horizontal line.

Furthermore, the number of the supporting rods is three.

Further, the connecting cylinder is in threaded connection with the measuring rod.

Furthermore, the surface of the measuring plate close to the connecting cylinder is provided with a T-shaped sliding groove, a clamping plate is connected in the sliding groove in a sliding mode, and the surface of the clamping plate close to the connecting cylinder is flush with the surface of the measuring plate close to the connecting cylinder.

Furthermore, one end of the support rod, which is far away from the connecting cylinder, is provided with vertical grabbing teeth.

Furthermore, the measuring rod is of a hollow tubular structure, an auxiliary reading rod is connected in the measuring rod in a sliding mode, scale marks are arranged on the auxiliary reading rod, and the zero scale marks of the auxiliary reading rod are flush with the end face, far away from the connecting cylinder, of the measuring rod; the measuring rod lateral wall is equipped with the spread groove, be equipped with on the supplementary reading pole with spread groove sliding fit's connecting block, the connecting block keep away from the one end of supplementary reading pole with measuring plate fixed connection.

The purpose of the invention is realized by the following technical scheme:

the invention has the beneficial effects that:

1) the invention can effectively ensure that the measuring and measuring device is horizontally attached to the two side surfaces of the floor slab, ensures the measuring precision, and has simple structure and convenient measurement.

2) The three bracing pieces that set up form stable contact point with the another side three point contact of floor, and the straightness that hangs down of assurance measuring stick that can be fine when three point simultaneous contact has avoided because of the measuring error that hangs down the straightness skew and cause simultaneously.

3) When the measuring plate slides, the connecting block drives the auxiliary reading rod to synchronously slide, when the measuring plate is in a measuring state, one end of the zero scale mark of the auxiliary reading rod extends out of the measuring rod, the scale of the end face of the measuring rod which is flushed with the auxiliary reading rod is thick at the moment, so that the arrangement avoids the problem that the floor slab needs to be adhered to the floor slab for reading because of the low height of the floor slab, the reading is convenient, and the measuring efficiency is improved.
