Description

Schmitthammer Rebound Hardness Measurement Point Positioning Device for Structural Safety Diagnosis {Rebound Hardness Position Marking Device for Structural Safety Diagnosis}

The present invention relates to a Schmidt hammer rebound hardness measurement point position display device for structural safety diagnosis, and more particularly to a plurality of measuring points applied to measure the rebound hardness of the Schmidt hammer used for measuring the rebound hardness for safety diagnosis of buildings, etc. The present invention relates to a Schmitthammer rebound hardness measuring point indicating device that can accurately and conveniently display a more reliable diagnosis of concrete structures.

In general, the safety diagnosis of buildings and civil structures is carried out to protect humans from disasters. The lifespan of buildings and civil structures is determined by natural factors such as temperature, temperature, humidity, topography, wind, and location. It is influenced by artificial factors.

Therefore, due to these factors, buildings and civil structures are often designed and built in spite of slip, sinking, working load, wind and earthquake, but they are often insufficiently designed and built by various factors. It also acts as a threat to safety.

Therefore, in such a case, safety inspections are conducted for each item such as on-site surveys and professional overviews, design criteria, and basic data, which are directly visited by technicians. It is true that it is insufficient in terms of securing safety.

Therefore, management systems and devices for professionally evaluating buildings have been developed and used. In particular, the resilience hardness measurement method is used for the safety inspection of concrete structures.

The method of measuring the rebound hardness is using a Schmidt hammer, the impact test for measuring the rebound hardness is caused by the deviation of the measured value depending on whether the aggregate is projected, the distance to the rebar, the roughness of the impact surface, etc. To reduce the error of measurement, draw 4 parallel horizontal lines on the concrete surface of the measurement object along the horizontal direction with 3cm in each direction using chalk and ruler, and then space each 3cm along the vertical direction so as to be perpendicular to the horizontal line. Five vertical lines are drawn, and the Schmidt hammer is hit at the orthogonal points (20 points) of each horizontal line and the vertical line to measure the hardness inside the concrete structure.

However, each time measuring the hardness of a concrete structure, drawing 5 (long) × 4 (horizontal) orthogonal straight lines with a spacing of 3 cm is very cumbersome in operation, depending on the manual operation of the operator, and takes a long time. Has disadvantages.

Therefore, in recent years, in order to solve such drawbacks, Korean Patent Publication No. 10-1229305 uses a stamp of a stamp type arranged at regular intervals in a horizontal and vertical direction to display a plurality of points on a plane at a time. Has been proposed. However, such a technique is limited to display only on the measurement surface made of a plane, and has a disadvantage in that it is difficult to display the measurement point in places such as circular columns and curved surfaces.

In addition, a sticker-type measuring point display device using an adhesive that can be attached to the surface of a curved structure has been filed as Utility Model Registration No. 200224542. It has the disadvantage of being difficult to use.

First, in the drawings, the same components or parts are to be noted that the same reference numerals as possible. In addition, in describing the present invention, a detailed description of related known functions or configurations will be omitted in order not to obscure the subject matter of the present invention.

Schmidt hammer rebound hardness measurement point position display device 100 for the structural diagnosis of the present invention is divided into a sticker part 110 and a stamp part 120, the sticker part 110 and the stamp part 120 is a fold line 130 is divided around the center.

The sticker part 110 may be formed on a sticker plate body 111 on which five (horizontal) × 4 (lateral) measuring point display holes 111a are spaced by 3 cm, and formed on one side of the sticker plate body 111. The surface 112 and the stamp pass hole 113a perforated to correspond to all the measurement point display holes 111a perforated on the sticker plate 111 are made of the adhesive surface protection vinyl 113 perforated.

At this time, the adhesive is applied to the adhesive surface 112 of the sticker plate body 111, but the adhesive is preferably made of a removable surface protective vinyl 113 is made of a removable component.

In addition, the stamp part 120 overlaps the sticker plate body 111 with a stamp plate body 120 having an adhesive coating surface 122 on one side thereof, and the stamp plate body 120 around the fold line combined fold line 130. The stamp seating is formed on the stamp plate body 120 so as to correspond to all the measurement point display holes (111a) perforated in the sticker plate body 111 and to be formed at the same position as each measurement point display hole (111a) of the sticker plate body (111) A surface 124, a sponge-like stamp 125 attached to the center of the stamp seating surface 124 and containing ink, and an adhesive coating surface to prevent the ink of the stamp 125 from being evaporated or damaged It consists of a stamp protection vinyl 123 attached to the (122).

At this time, the adhesive coated surface 122 of the stamp plate body 120, but the adhesive is applied, the adhesive is preferably made of a stamp protective vinyl 123 is a removable component.

At this time, between the sticker plate body 111 and the stamp plate body 120 is formed with a cut line combined fold line 130, the cut line combined fold line 130 is also used as a cut line, fold line, that is to facilitate folding Sometimes used as a line.

That is, the case where the cut line combined fold line 130 is used as a cut line is necessary when the present invention is used only as a sticker method.

In other words, when the present invention is used only in the sticker method, since the stamp part 120 is not necessary, only the sticker plate 111 should be cut off.

In addition, when the cut line combined fold line 130 is used as a fold line is required when the present invention is used only in the stamp method.

In other words, when the present invention is used only in the stamp method, the stamp part 120 should be folded around the tear line combined fold line 130 while the sticker part 110 is located on the measurement surface A. FIG.

Thus, when the stamp part 120 is folded in the state where the sticker part 110 is located on the measurement surface A, the sponge-shaped stamp 125 attached to the center of each stamp seating surface 124 and containing ink is formed. While touching the measuring surface A, the measuring point C is marked at the center of all the measuring point display holes 111a of the sticker plate body 111.

As such, when the measuring point C is marked on the measuring surface A, the resilience hardness can be measured by hitting each measuring point C with the Schmidt hammer B.

Therefore, the cut line combined fold line 130 is easy to cut, it is preferable to form in a way to put out a certain interval to facilitate folding.

As described above, although the present invention has been described by way of limited embodiments, the present invention is not limited thereto, and the technical concept of the present invention and the following will be described by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of the appended claims.
