Description
본 고안은 콘크리트 테스트 해머용 보조도구에 관한 것으로, 특히 토목 및 건축 현장에서 콘크리트 테스트 해머의 타격위치를 쉽고 정확하게 나타낼 수 있게 한 것이다.The present invention relates to an auxiliary tool for the concrete test hammer, and in particular, it is possible to easily and accurately represent the hitting position of the concrete test hammer in civil engineering and construction sites.
일반적으로, 건설 현장에서 콘크리트 구조물의 강도를 측정하기 위해서는 콘크리트면에 일정한 간격으로 타격위치를 표시하고 표시된 위치를 콘크리트 테스트 해머(일명, 슈미트해머라고도 함.)로 타격하여 콘크리트의 강도를 측정하는 방법을 사용하고 있다.In general, in order to measure the strength of the concrete structure in the construction site to mark the location of the striking at regular intervals on the concrete surface and hit the marked position with a concrete test hammer (aka, Schmidt hammer) to measure the strength of the concrete I'm using.
도 1은 종래 콘크리트 테스트 해머의 타격위치를 표시하는 타격위치 표시도이다.1 is a hitting position display showing the hitting position of the conventional concrete test hammer.
이것은 콘크리트 벽면에 분필로 3cm 간격의 선분을 가로 또는 세로 방향으로 등간격으로 긋고, 이와 직교하는 선분을 3cm 간격으로 등간격으로 다시 그음으로써 가로 세로의 길이가 3cm인 격자 형태를 이루게 한 것이다.This is made by drawing a line of 3cm intervals in chalk on the concrete wall at equal intervals in the horizontal or vertical direction, and redrawing the orthogonal segments at equal intervals in 3cm intervals to form a grid with a length of 3cm.
이와 같이 가로세로 방향으로 5개 정도의 선분을 교차시켜 교차점을 이루게 한 뒤, 각 선분의 교차점을 콘크리트 테스트용 해머로 타격한다.Thus, after crossing five lines in the vertical and horizontal direction to form an intersection, the intersection of each line is hit with a hammer for concrete test.
그런데, 현장에서 해당 콘크리트면에 분필로 정확히 3cm의 선분을 등간격으로 긋기 위해서는 별도의 자가 필요할 뿐만 아니라, 그리는데 시간이 걸리는 단점이 있다. 또한, 천정이나 장소가 협소한 곳에서는 이와 같은 방법을 사용하기에 불편한 점이 많았다.However, in order to draw a line segment of exactly 3cm with chalk on the concrete surface at equal intervals, a separate ruler is required and draws time to draw. In addition, there were many inconveniences in using such a method in places where the ceiling and the place were narrow.
본 고안은 상술한 바와 같은 종래의 문제점을 해소하기 위해 안출된 것으로, 본 고안은 콘크리트면에 빠르고 정확하게 테스트 해머의 타격위치를 표시할 수 있는 콘크리트 테스트 해머용 보조도구를 제공하는 것이다.The present invention is devised to solve the conventional problems as described above, the present invention is to provide an auxiliary tool for a concrete test hammer that can quickly and accurately display the impact position of the test hammer on the concrete surface.
상술한 목적을 달성하기 위한 본 고안은, 콘크리트 구조물의 강도 측정시 콘크리트면에 해머의 타격위치를 표시하기 위한 장치에 있어서, 오와 열을 따라 일정한 간격으로 관통구멍이 형성된 규격판과, 이 규격판의 일측에 부착된 위치 고정용 손잡이로 이루어지는 것을 특징으로 한다.The present invention for achieving the above object, in the device for indicating the impact position of the hammer on the concrete surface when measuring the strength of the concrete structure, the standard plate formed with a through hole at regular intervals along the wah and heat, Characterized in that consisting of a position fixing handle attached to one side.
이와 같은 본 고안에 의하면, 규격판을 콘크리트면에 밀착시키고 그 전면에서 스프레이 페인트를 분사하면 규격판에 형성된 관통구멍을 통과한 페인트가 벽면에 흡착하게 됨으로써 해머의 타격위치를 표시하게 된다. 따라서, 격자를 그리는 시간을 줄일 수 있을 뿐만 아니라, 측정자의 편의를 도모하여 작업의 효율을 높일 수 있게 된다.According to the present invention, when the standard plate is in close contact with the concrete surface and the spray paint is sprayed from the front surface of the standard plate, the paint passing through the through-hole formed in the standard plate is adsorbed on the wall, thereby indicating the hammering position of the hammer. Therefore, the drawing time of the grating can be reduced, and the efficiency of the work can be increased by the convenience of the measurer.

이와 같은 본 고안의 특징적인 구성 및 이에 따른 작용효과는 첨부된 도면을 참조한 실시예의 상세한 설명을 통해 더욱 명확해 질 것이다.Such a characteristic configuration and the effect according to the present invention will be more clear through the detailed description of the embodiments with reference to the accompanying drawings.
도 2, 도 3은 본 고안에 따른 콘크리트 테스트 해머용 보조도구를 나타낸 것이다.Figure 2, Figure 3 shows an auxiliary tool for a concrete test hammer according to the present invention.
이것은 콘크리트 구조물의 강도 측정시 콘크리트면에 해머의 타격위치를 표시할 수 있게 하는 것으로, 오와 열을 따라 일정한 간격으로 관통구멍(11)이 형성된 규격판(10)과, 이 규격판(10)의 일측에 부착된 위치 고정용 손잡이(20)로 이루어져 있다.This makes it possible to mark the impact position of the hammer on the concrete surface when measuring the strength of the concrete structure, a standard plate 10 having a through hole 11 formed at regular intervals along the rows and rows, and one side of the standard plate 10 Consists of a position fixing knob 20 attached to.
규격판(10)은 가로세로 20cm 정도의 면적을 갖는 정사각형의 평판체로 이루어지며, 각 관통구멍(11) 사이의 간격은 그 중심과 중심 사이를 기준으로 3cm로 정해진다.The standard plate 10 is formed of a square flat body having an area of about 20 cm in width, and the spacing between each through hole 11 is set to 3 cm based on the center and the center.
실시예로써 도시된 규격판(10)은 0.3cm의 두께를 갖는 아크릴판으로 형성되고, 관통구멍(11)은 0.5cm의 직경크기로 가로세로 5개씩 총 25개가 천공된다.Standard plate 10 shown as an embodiment is formed of an acrylic plate having a thickness of 0.3cm, the through-hole 11 is a total of 25 perforated 5 by 5 by a diameter size of 0.5cm.
손잡이(20)는 규격판(10)을 벽면에 위치 고정시킬 때 손으로 잡을 수 있게 하기 위한 것으로, 규격판(10)의 일단에 대략 45°의 경사각으로 조립된 연결부(21)와 일체로 이루어지고, 편리한 자세에서 손으로 잡을 수 있도록 규격판(10)과 대략 평행하게 형성된다.The handle 20 is intended to be held by hand when the standard plate 10 is fixed on the wall, and is integrally formed with a connection part 21 assembled at an inclination angle of approximately 45 ° at one end of the standard plate 10. It is formed to be approximately parallel with the standard plate 10 so that it can be held by hand in a convenient posture.
이와 같은 본 고안에 따른 콘크리트 테스트 해머용 보조도구를 이용하여 타격위치를 표시하고자 하는 경우, 관통구멍(11)이 형성된 규격판(10)을 콘크리트 구조물의 표면에 밀착시킨 뒤, 그 위에 스프레이 페인트를 분사한다. 이와 같이 하면 구멍(11)을 통과한 페인트만이 콘크리트 표면에 묻게됨으로써, 해머의 타격위치를 콘크리트면에 정확하게 표시할 수 있게 된다.In order to display the impact position by using the auxiliary tool for the concrete test hammer according to the present invention, the standard plate 10 having the through hole 11 is in close contact with the surface of the concrete structure, and then sprayed with spray paint thereon. do. In this way, only the paint having passed through the hole 11 is buried on the concrete surface, whereby the hammering position of the hammer can be accurately displayed on the concrete surface.
따라서, 종래의 방법에 의한 격자를 그리는 시간을 줄임으로써 신속한 작업이 가능하게 되며, 자를 대고 선을 긋는 단순 반복작업에 의한 불편함을 해소하여 작업효율을 향상시킬 수 있게 된다.Therefore, it is possible to quickly work by reducing the time for drawing the grid by the conventional method, it is possible to solve the inconvenience by the simple repetitive work to draw a line to the ruler to improve the work efficiency.
또한, 본 고안에 따른 콘크리트 테스트 해머용 보조도구는 천정이나 장소가 협소한 곳에서도 사용이 가능한 편리함을 제공한다.In addition, the auxiliary tool for concrete test hammer according to the present invention provides a convenience that can be used even in a narrow ceiling or place.
위에서 설명한 바와 같이 본 고안에 의하면, 규격판을 콘크리트면에 밀착시키고 그 전면에서 스프레이 페인트를 분사함으로써 구멍을 통과하여 콘크리트면에 흡착된 페인트에 의해 해머의 타격위치를 표시할 수 있게 된다.As described above, according to the present invention, it is possible to indicate the impact position of the hammer by the paint adsorbed to the concrete surface by passing the hole by adhering the standard plate to the concrete surface and spraying spray paint from the front surface thereof.
따라서, 종래에 비해 신속 정확한 작업이 가능할 뿐만 아니라, 측정자의 편의를 도모하여 작업의 효율을 향상시킬 수 있게 된다.Therefore, not only is it possible to work faster and more accurately than in the related art, but also it is possible to improve the efficiency of the work by facilitating the convenience of the measurer.
