Description

확대경과 조명이 부착된 균열폭 측정자 {CRACK WIDTH METER TO WHICH MAGNIFIER AND FLASH LIGHT IS ATTACHED}CRACK WIDTH METER TO WHICH MAGNIFIER AND FLASH LIGHT IS ATTACHED}

본 발명은 건물 및 구조물의 균열폭을 측정하기 위한 균열폭 측정자에 관한 것으로, 특히 어두운 장소에서도 구조물의 미세한 균열까지 정확하게 측정할 수 있는 확대경과 조명이 부착된 구조물 균열폭 측정자에 관한 것이다.The present invention relates to a crack width measurer for measuring the crack width of buildings and structures, and more particularly to a structure crack width meter with a magnifying glass and light that can accurately measure the fine cracks of the structure even in a dark place.

일반적으로, 도시 근교에서 진행되는 전기 통신구용 관로 매설공사는 실드(Shield)공법, 추진공법 등의 비개착공법에 의한 것이 많아지고 있으나, 이들 공사에 따른 진동 또는 지반침하 등의 영향으로 근방의 지하매설물이나 지상구조물에 해를 미치게 되는 일이 있다.In general, pipe laying works for telecommunications in urban suburbs are being increased by non-opening methods such as shield method and propulsion method, but due to the vibration and ground subsidence, It may cause damage to the burial or ground structure.

이와 같이 진동 또는 지반침하의 영향을 받게 되면 균열이 발생하기 쉬운데, 균열이 심화되면 구조물의 붕괴 위험을 초래하게 되므로 정기적으로 안전점검을 실시하여 균열폭의 변화를 측정하게 된다.In this way, when the vibration or ground subsidence is affected, cracks are likely to occur. If the cracks are intensified, a risk of collapse of the structure is caused. Therefore, the safety check is periodically performed to measure the change in crack width.

도 1은 구조물의 균열폭을 측정하기 위해 기존에 사용되고 있는 균열폭 측정카드를 도시한 것으로, 얇은 두께를 가진 사각형의 투명판 형태로 이루어져 있고 표면에는 눈금과 수치가 기재되어 있다. 따라서, 균열부위에 대고 균열폭을 측정할 수 있도록 되어 있다.Figure 1 shows a conventional crack width measurement card for measuring the crack width of the structure, consisting of a rectangular transparent plate having a thin thickness and the scale and numerical values are described on the surface. Therefore, the crack width can be measured at the crack portion.

그러나, 이러한 종래의 균열폭 측정카드는 미세한 균열을 측정하기에 곤란할 뿐만 아니라, 어두운 장소에서는 별도의 조명장치를 필요로 하게 된다.However, such a conventional crack width measuring card is not only difficult to measure fine cracks, but also requires a separate lighting device in a dark place.

한편, 도시되진 않았으나 현재 개발되어 있는 균열폭 측정장치중에서는 현미경에 조명장치가 결합된 제품이 있으나, 이와 같은 경우에도 건물의 천정 등에 형성된 균열을 측정하려면 사다리 등을 이용하여 천장에 가까이 접근한 뒤 현미경을 균열 발생지점에 대고 눈을 렌즈 가까이 밀착하여 초점을 맞추면서 균열폭을 측정해야 하므로 작업이 매우 비능률적인 문제점이 있다.On the other hand, although not shown in the current crack width measuring device is a product that combines the lighting device with the microscope, in this case also to measure the crack formed in the ceiling of the building, using a ladder, etc. close to the ceiling after the microscope Since the crack width should be measured while focusing by focusing the eye close to the lens at the point of crack generation, the work is very inefficient.

본 발명은 상술한 바와 같은 종래의 문제점을 해소하기 위한 것으로, 본 발명의 목적은 어두운 장소에서도 구조물 표면의 미세한 균열을 정밀하게 측정할 수 있는 확대경과 조명이 부착된 구조물 균열폭 측정자를 제공하는 것이다.The present invention is to solve the conventional problems as described above, it is an object of the present invention to provide a structure crack width measuring device with a magnifying glass and illumination that can accurately measure the minute cracks on the surface of the structure even in a dark place.

상술한 목적을 달성하기 위한 본 발명은, 건물 및 구조물 표면의 균열폭을 측정하기 위한 장치에 있어서, 하우징 내부에 전지수납구가 형성되고, 하우징 일측면에는 전지수납구의 전원회로와 연결된 조명등이 장착되며, 인접한 타측에는 전원회로를 개폐하는 전원스위치가 구비된 조명부와; 이 조명부의 일측 하단에 구비되어 조명등의 하측에 위치되며, 눈금 및 수치가 일정한 간격으로 표시된 투명판으로 이루어진 균열 측정부와; 조명부의 일측 상단에 균열 측정부와 평행하게 구비된 확대경으로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, in the device for measuring the crack width of the surface of the building and structure, the battery compartment is formed inside the housing, one side of the housing is equipped with a light and the like connected to the power circuit of the battery compartment, The other side adjacent to the lighting unit having a power switch for opening and closing the power circuit; A crack measurement unit provided at one lower end of the lighting unit and positioned below the lighting lamp, the crack measuring unit including a transparent plate on which graduations and numerical values are displayed at regular intervals; Characterized in that consisting of a magnifying glass provided in parallel with the crack measuring unit on the upper end of the lighting unit.

이와 같은 본 발명에 의한 균열폭 측정자는 균열 측정부를 통해 관찰되는 균열부분이 확대경으로 확대되어 보여지게 됨으로써 미세한 균열에 대해서도 균열폭을 정확하게 측정할 수 있게 된다. 또한, 스위치를 켜면 조명부가 균열 측정부를 조명하게 됨으로써 지하실이나 터널 등 어두운 장소에서도 편리하게 사용할 수 있다.The crack width measurer according to the present invention can accurately measure the crack width even for minute cracks because the crack portion observed through the crack measuring unit is enlarged by the magnifying glass. In addition, when the switch is turned on, the illumination unit illuminates the crack measurement unit, so it can be conveniently used in a dark place such as a basement or a tunnel.

At this time, the scale 21 normally displays the thickness up to 0.05-0.80 mm, and the fluctuation range consists of 0.05 mm units.

조명부(10)는 하우징(11) 내부에 전지수납구(12)가 형성되고, 하우징(11)의 일측면에는 전지수납구(12)의 전원회로와 연결되는 조명등(13)이 장착되며, 전면에는 전원회로를 개폐하는 전원스위치(14)가 구비된다. 균열 측정부(20)는 하우징(11)의 일측면 하단에 구비됨으로써 조명등(13)의 아래쪽에 위치하게 된다.The lighting unit 10 has a battery compartment 12 is formed in the housing 11, one side of the housing 11 is equipped with a lamp 13 connected to the power circuit of the battery compartment 12, the front of the power supply A power switch 14 for opening and closing the circuit is provided. The crack measuring unit 20 is provided at the lower side of one side of the housing 11 to be positioned below the lamp 13.

조명부(10)의 전원은 1.5V 건전지의 전원을 직렬로 연결시켜 이용하며, 조명등(13)은 균열 측정부(20)를 균일하게 조명할 수 있도록 하우징(11)의 측면 전방으로 다소 돌출된 상태에서 하방으로 적절한 경사각을 지니도록 부착된다.The power of the lighting unit 10 is used by connecting the power of the 1.5V battery in series, the lamp 13 is a state protruded slightly toward the front of the side of the housing 11 to uniformly illuminate the crack measuring unit 20 It is attached to have a proper inclination angle downward from.

한편, 하우징(11)에는 균열폭의 크기에 따라 작업자가 참조할 수 있도록 인쇄된 표를 부착할 수도 있을 것이다.On the other hand, the housing 11 may be attached to the printed table for reference by the operator according to the size of the crack width.

표는 다음과 같은 내용을 포함한다.The table includes:

균 열 폭(mm)Crack width (mm) 상 태condition 0.05 ∼ 0.200.05-0.20 양 호Good 0.25 ∼ 0.400.25-0.40 관찰 필요Observation required 0.45 ∼ 0.600.45-0.60 보수 필요Need repair 0.65 이상0.65 or more 진단 필요Diagnostic required

그리고, 확대경(30)은 하우징(11) 상단에 균열 측정부(20)와 나란하게 구비되어 균열 측정부(20)를 확대하여 볼 수 있게 한다.In addition, the magnifying glass 30 is provided in parallel with the crack measuring unit 20 at the upper end of the housing 11 to enlarge and view the crack measuring unit 20.

이와 같은 구조로 이루어진 본 발명에 따른 균열폭 측정자는 균열 측정부(20)를 건물 또는 구조물에 발생된 균열부위에 밀착시키고 그 전면에서 확대경(30) 통해 보게 되면, 균열부분이 실제의 크기보다 확대되어 보여지게 됨으로써 미세한 균열까지도 정확하게 측정할 수 있게 된다. 특히, 확대경(30)의 초점이 균열 발생부(20)에 미리 맞추어져 있으므로, 사용도중 배율조정을 하는 등의 불편함이 배제된다.When the crack width measurer according to the present invention having such a structure is in close contact with the crack measurement part 20 generated in the building or structure and viewed through the magnifying glass 30 from the front, the crack part is enlarged than the actual size. This makes it possible to accurately measure even minute cracks. In particular, since the focal point of the magnifying glass 30 is set in advance to the crack generating unit 20, inconvenience such as adjusting the magnification during use is eliminated.

또한, 스위치(14)를 켜면 조명등(13)이 균열 측정부(20)를 조명하게 됨으로써 지하실이나 터널 등 어두운 장소에서도 별도의 조명이 필요치 않게 된다.In addition, when the switch 14 is turned on, the lamp 13 illuminates the crack measuring unit 20, so that no separate lighting is required even in a dark place such as a basement or a tunnel.

따라서, 건물의 천정 등에 발생한 미세한 균열을 측정할 때에도 위에서 설명한 바와 같은 방법으로 편리하게 사용할 수 있게 된다.Therefore, even when measuring the minute cracks generated in the ceiling of the building, it can be conveniently used in the manner described above.
