Description

Technical Field

[0001] The utility model belongs to the technical field of building test detection, and specifically relates to a concrete compressive strength rebound detection area and a measuring point plotter. Background Art

[0002] During the test of concrete compressive strength by rebound method, it is necessary to divide the concrete test surface into test areas for sampling test. The Technical Regulations for Testing Concrete Compressive Strength by Rebound Method require that a test area should not be larger than 0.04 m2, and a test area should be divided into 16 test points. Each test point should have a net distance of no less than 20 mm from the adjacent test points.

[0003] In the existing test and inspection process, test and inspection personnel usually use rulers or tape measures to manually measure distances, and use chalk or markers to draw the measurement area. Some test and inspection personnel even draw the measurement area by hand without using auxiliary tools such as rulers. In the drawing process, it is easy to produce errors due to human factors, so that the measurement area and the net distance between adjacent measurement points do not meet the requirements of the technical regulations for the rebound method for testing the compressive strength of concrete, resulting in insufficient reliability of the test and inspection data. In addition, the efficiency is low when drawing with chalk or markers.

[0004] Therefore, how to quickly and accurately draw the measuring area and measuring points on the concrete testing surface in accordance with the requirements of the "Technical Specifications for Testing Concrete Compressive Strength by Rebound Method" has been a problem that technical personnel in this field have been waiting to solve.

[0026] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0027] refer to Figure 1 to Figure 3 As shown, a concrete compressive strength rebound detection area and measuring point plotter includes an ink tank 1, an ink filling port 2, an ink filling cover 3, a drawing skeleton 4, a drawing grid 5, a drawing measuring point 6, a sponge 7, a sealing cover 8 and a buckle 9.

[0028] The ink tank 1 is a square flat structure to match the shape of the measuring area, and its interior is a relatively closed chamber for containing ink (ink includes but is not limited to ordinary ink, anti-fading ink, automatically disappearing ink, etc., which can be selected according to the needs of the engineering site).

[0029] An ink injection port 2 connected to the ink tank 1 is provided at the center of the upper part thereof, and ink can be filled into the ink tank 1 or unused ink can be poured out through the ink injection port 2. A detachable ink injection cap 3 is provided on the ink injection port 2, and the ink tank 1 is sealed by installing the ink injection cap 3, and the ink is filled or poured out by removing the ink injection cap 3. A spiral connection structure is adopted between the ink injection port 2 and the ink injection cap 3, and a layer of sealing gasket is preferably provided at the bottom of the cap, which can ensure the sealing performance when installed and facilitate the removal operation.

[0030] The lower part of the ink tank 1 is connected to the upper part of the drawing frame 4. The ink tank 1 and the drawing frame 4 are glued or integrated to form a whole. However, no matter which connection method is used, the ink outlet of the ink tank 1 needs to be opposite to the passage inside the drawing frame 4 to achieve the through flow of ink. The drawing frame 4 also has a square flat structure to ensure that it is consistent with the shape of the ink tank 1. The interior of the drawing frame 4 is a hollow structure to form a passage.

[0031] The lower part of the drawing skeleton 4 forms a drawing grid 5 and a drawing measuring point 6. The drawing grid 5 is a plurality of grid plate structures staggered horizontally and vertically, and the drawing grid 5 forms a plurality of square grids arranged horizontally and vertically to form the action sites of the plurality of square grids in the measurement area. The drawing measuring point 6 is located at the center of the grid of the drawing grid 5, and the drawing measuring point 6 is a vertical rod structure to form the action sites of the plurality of circular measuring points in the measurement area.

[0032] The lower end surfaces of the drawing grid 5 and the drawing measuring point 6 are both provided with a sponge 7. The ink tank 1 is connected to the sponge 7 through the internal passage of the drawing frame 4, so that the ink in the ink tank 1 can flow into the sponge 7 through the internal passage and be wrapped and absorbed by the sponge 7. The entire drawing device is pressed down so that the sponge 7 comes into contact with the concrete surface, and the ink in the sponge 7 is squeezed out and seeps onto the concrete surface, thereby achieving the drawing of the grids and points in the measuring area.

[0033] The sponge 7 on the drawing grid 5 and the drawing measuring point 6 is located at the same height, and the thickness of the sponge is preferably the same. At the same time, the lower end surface heights of the drawing grid 5 and the drawing measuring point 6 are also the same, which can maximize the guarantee that the ink penetrates evenly when the drawing tool is pressed.

[0034] The sponge 7 is a high-density microporous sponge, which has a good adsorption effect on ink. The drawing frame 4 and the sponge 7 are glued to ensure that the sponge 7 is fixed on the frame 4 to prevent it from falling off.

[0035] The lower part of the drawing frame 4 is detachably connected to the sealing cover 8, which is set on the drawing grid 5 and the drawing measuring point 6. When the drawing device is idle, the sealing cover 8 keeps the interior in a closed state to prevent the ink in the drawing device from being dried. Preferably, buckles 9 are provided on the four outer sides of the lower part of the drawing frame 4, and the sealing cover 8 is clamped on the buckles 9, which is very convenient for installation and removal.

[0036] The workflow of this utility model:

[0037] Step 1: Unscrew the ink filling cap, inject ink (ink includes but is not limited to ordinary ink, anti-fading ink, automatic disappearing ink, etc., which can be selected according to the needs of the project site) into the ink tank from the ink filling port, and tighten the ink filling cap.

[0038] Step 2: The ink flows into the plotter frame through the ink tank, and the high-density microporous sponge absorbs the ink in the plotter frame.

[0039] Step 3: Remove the sealing cover of the snap-on plotter, point the bottom of the plotter toward the surface of the concrete component, and gently press the plotter. The surface of the concrete component will show measurement areas and measurement points that meet the requirements of technical regulations.

[0040] Step 4: After mapping multiple measurement areas and points in accordance with technical regulations, put the snap-on plotter sealing cover back to its original position to complete the use of the plotter.

[0041] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
