Description
본 발명은 교량받침(支承;bearing support) 신축 측정계에 관한 것으로, 특히 계절에 관계없이 교량의 최대 신축거리를 측정할 수 있고, 교량받침의 설치년월 및 설치 당시의 온도 등과 같은 사항을 파악할 수 있는 측정계에 관한 것이다.The present invention relates to a bearing support telescopic measuring system, and in particular, it is possible to measure the maximum stretching distance of the bridge regardless of the season, it is possible to grasp the matters such as the year and year of installation of the bridge support It relates to a measuring system.
일반적으로 교량에는 상부구조에서 받는 힘을 하부구조로 전달하기 위해 상기 상부구조와 하부구조의 경계에 지지장치인 받침을 설치하는데, 이러한 받침은 기능적으로 보아서 교량을 고정하는 지점(고정점)에 설치하는 고정받침과 하부구조에 대한 상부구조의 이동을 원할하게 하는 지점(가동점)에 설치하는 가동받침으로 대별되며, 가동받침은 좌.우로만 가동하는 일방향 받침과 좌.우.종.횡으로 가동하는 양방향 받침이 있다.In general, bridges are installed on the boundary between the superstructure and the undercarriage to transfer the force received from the superstructure to the undercarriage, which is functionally installed at a point (fixed point) to fix the bridge. It is roughly divided into a movable support installed at a fixed point and a movable support installed at a point (moving point) to smoothly move the upper structure with respect to the substructure. There is a two-way stand running.
이들 가운데 가동받침은 상판 구조물인 강재나 콘크리트의 온도변화, 건조수축, 크리프 등에 의한 교량의 이동을 원활하게 하는 구조로 하는 것이 필요하며, 그 종류로는 금속받침, 고무받침 등이 있다.Among these, the movable support needs to have a structure that facilitates the movement of the bridge due to temperature change, drying shrinkage, creep, etc. of steel or concrete, which is a top plate structure, and includes metal supports and rubber supports.
상기와 같은 가동받침은 여러 외적 조건(온도변화나 진동)에 따라 교량의 상부 구조가 늘어나거나 또는 줄어드는 등 교량의 이동(신축작용)을 하게되는데, 이에 따라 이 가동받침도 종.횡방향으로 이동하게 된다.The movable support as described above performs the movement (stretching) of the bridge by increasing or decreasing the upper structure of the bridge according to various external conditions (temperature change or vibration). Accordingly, the movable support also moves vertically and horizontally. Done.
즉, 받침의 하단은 교량의 하부구조에 결합되어 고정되고 상단은 교량의 상부구조에 결합되어 고정되기 때문에, 상기 교량의 상부구조가 신축함에 따라 받침의 상단이 이동하는 것이다.That is, since the lower end of the base is fixedly coupled to the lower structure of the bridge and the upper end is fixedly coupled to the upper structure of the bridge, the upper end of the base is moved as the upper structure of the bridge is stretched.
이와 같은 교량의 신축량은 교량의 안전점검시 점검대상이 되며, 이 신축량을 측정하기 위해 상기 받침에 측정계를 설치하여 사용한다.The amount of expansion and contraction of such bridges is subject to inspection at the time of safety inspection of the bridge, and a measuring system is installed on the support to measure the amount of expansion and contraction.
이러한 측정계는 받침의 상단에는 눈금이 인쇄된 측정판을 설치하고, 하단에는 몸체의 상단에 지시침이 형성된 지시계를 설치하되, 상기 지시계의 지시침이 측정판에 인쇄된 눈금의 중앙에 위치하도록 하여 사용하는 것이다.Such a measuring system is installed on the top of the base of the measuring plate is printed with a scale, the bottom of the body is installed an indicator with an indicator needle formed on the top, so that the indicator of the indicator is located in the center of the scale printed on the measuring plate Is to use.
즉, 교량의 신축에 따라 받침의 하단은 고정된 상태로 있고 상단은 좌, 우로 움직이게 되는데, 상기 지시계는 받침의 하단에 설치되고 측정판은 상단에 설치되어 있으므로, 교량의 신축에도 불구하고 지시계는 고정된 상태로 있고, 측정판은 받침의 상단과 같이 움직인다.That is, according to the construction of the bridge, the bottom of the base is fixed and the top is moved to the left and right. The indicator is installed at the bottom of the base and the measuring plate is installed at the top. It remains fixed and the measuring plate moves with the top of the base.
따라서, 지시계의 지시침이 설치 당시에는 측정판에 인쇄된 눈금의 중앙에 위치하고 있었으나, 상기 측정판의 이동으로 눈금의 중앙에서 좌측 또는 우측으로 이동되어 위치하게 되므로, 점검시 이동된 거리를 눈금으로 측정하여 파악하는 것이다.Therefore, the indicator hand of the indicator was located at the center of the scale printed on the measurement plate at the time of installation, but moved to the left or right from the center of the scale by the movement of the measurement plate, so that the distance moved during the inspection To measure and grasp.
그러나 상기와 같이 측정계는 특정 계절에 측정하여야 비교적 정확한 측정이 이루어지기 때문에 다른 계절에는 측정을 할 수 없을뿐 아니라 측정이 이루어져도 정확한 값이 아닌 추정값 밖에 얻을 수 없다는 문제점이 있어왔다.However, as described above, the measurement system has a problem that it is not possible to measure in other seasons because the measurement system is measured in a specific season, and that only the estimated value is obtained, not the exact value.
즉, 교량의 상부구조가 신축되는 폭은 계절적 기후 특성에 따라 상이하며, 그날 그날의 기후와 교통량에 따라 변하는데, 1년중 교량의 신축이 최대가 되는 시점이 언제인지를 알 수 없어 이를 관찰하기 위해 관찰자가 주야로 계속하여 관찰한다는 것이 현실적으로 불가능하다.In other words, the width of the bridge's superstructure is different depending on the seasonal climate and changes depending on the weather and traffic of the day, and it is not possible to know when the construction of the bridge is at its maximum during the year. It is practically impossible for the observer to observe day and night.
따라서, 상기와 같은 이유로 인해 신축되는 폭이 최대가 될 것으로 예상되는 날(또는 기간)을 매년 지정하고 이 날(또는 기간)에 측정된 값(기간에 측정된 평균값)을 교량의 최대 신축값으로 추정하여 교량 보수 등의 자료로 이용하고 있으나, 기후변화나 교통량을 정확하게 예측하고 최대 신축량을 측정한다는 것이 어려운 것이어서 상기와 같은 측정값은 최대치에 대한 추정일뿐 정확한 값은 아니고, 이러한 측정은 계절적 특성에 따라 다른 계절에는 할 수 없고 혹한기, 혹서기 등 특정 계절에만 행하여야 하는 문제점이 있어왔다.Therefore, for each of these reasons, specify a day (or period) for which the stretched width is expected to be the maximum each year, and the value measured on this day (or period) (the average value measured for the period) is the maximum stretch value of the bridge. Although it is estimated and used as data for bridge repairs, it is difficult to accurately predict climate change or traffic volume and measure the maximum stretch, so these measurements are only estimates of the maximum and not accurate. Therefore, there is a problem that should be performed only in certain seasons such as cold season, cold season, and can not do in other seasons.
따라서, 이를 극복하고자 교량의 받침에 최대 신축량 측정센서를 설치하여 사용하는 경우가 있으나, 센서의 설치비용과 관리비용이 과다하게 부담되고 관리 또한 어려워서 모든 교량에 설치한다는 것이 현실적으로 불가능하다.Therefore, in order to overcome this, there is a case in which the maximum stretch sensor is installed and used in the support of the bridge, but the installation cost and the management cost of the sensor are excessively burdened and difficult to manage, so it is practically impossible to install it on all bridges.
또한, 받침의 점검시 상기와 같이 측정한 신축값과 받침의 제작자, 설치년월, 용량, 설치위치, 설치온도, 설계신축량 등을 종합적으로 비교하여 기록하여야 하는데, 상기 제작자, 설치년월, 용량, 설치위치, 설치온도, 설계신축량 등을 확인하기 위해서는 별도로 기록한 설계도서를 찾아 열람하여야 알 수 있기 때문에 일이 번거롭다는 문제점이 있어왔다.In addition, when checking the bearings, the new value measured as described above and the bearing manufacturer, installation month, capacity, installation location, installation temperature, and design extension amount should be comprehensively recorded. In order to check the location, installation temperature, design expansion amount, etc., there is a problem that work is cumbersome because it is necessary to find and read separately recorded design books.
본 발명은 상기와 같은 문제점을 해결하기 위해 발명한 것으로, 본 발명의 목적은 계절과 교통량에 관계없이 어느때라도 교량의 최대 신축값을 측정할 수 있고, 제작자, 설치년월, 용량, 설치위치, 설치온도, 설계신축량 등도 현장에서 즉시 파악할 수 있는 측정계를 제공하여 교량의 상태를 용이하게 파악하고, 이를 토대로 보수여부 등을 신속하게 판단하여 교량의 수명을 연장시킬 수 있도록 하는 것이다.The present invention has been invented to solve the above problems, the object of the present invention is to measure the maximum stretch value of the bridge at any time, regardless of the season and traffic volume, the manufacturer, date of installation, capacity, installation location, installation By providing a measuring system that can be immediately understood at the site, such as temperature and design stretch, it is possible to easily understand the condition of the bridge and to quickly determine whether it is to be repaired and to extend the life of the bridge.

한편, 첨부한 도면 도 3 내지 도 4는 본 발명에 의한 측정계의 다른 실시예를 도시한 정면도 및 단면도로서, 상기 도면에서와 같은 본 발명의 다른 실시예의 구성은 측정판(11a)에 인쇄된 눈금의 좌, 우측에 명판(15)을 형성하는 것은 본 발명의 실시예와 같으나, 측정구(18a)는 중앙에 돌기(18b)를 형성하여 구비하고, 상기 측정구(18a)가 삽입될 수 있도록 측정판(11a)의 뒷면 일측에 측정구 삽입홈 (16a)을 형성하며, 이 측정구 삽입홈(16a)에서 측정판(11a)의 전면으로 측정구 (18a)의 돌기(18b)가 돌출될 수 있도록 장공(16b)을 형성하여 측정계(10)를 구성하는 것이다.3 to 4 are front and cross-sectional views showing another embodiment of the measuring system according to the present invention. The configuration of another embodiment of the present invention as shown in the drawing is printed on the measuring plate 11a. Forming the name plate 15 on the left and right of the scale is the same as the embodiment of the present invention, the measuring sphere (18a) is provided by forming a projection (18b) in the center, the measuring sphere (18a) can be inserted The measuring tool insertion groove 16a is formed on the rear side of the measuring plate 11a so that the protrusion 18b of the measuring tool 18a protrudes from the measuring tool insertion groove 16a to the front of the measuring plate 11a. To form the long hole (16b) to be configured to configure the measurement system (10).
상기와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
눈금이 인쇄되고 상기 눈금의 좌, 우측에 명판(15)을 형성한 측정판(11)을 받침(20)의 상측에 설치하고, 몸체(13)와 지시침(14)으로 이루어진 지시계(12)를 받침(20)의 하측에 설치하되, 상기 지시계(12)의 몸체(13)는 받침(20)의 하측에 고정설치되고, 지시침(14)은 측정판(11)의 하단에 형성한 지시침 삽입홈(17)에 삽입 관통되어 그 선단이 눈금의 중앙부분을 지시하도록 하며 측정판(11)의 측정구 삽입홈(16)에 삽입된 측정구(18)는 상기 지시침(14)의 좌, 우측에 각각 위치하도록 한다.An indicator 12 having a measuring plate 11 having a scale printed thereon and a name plate 15 formed on the left and right sides of the scale mounted on an upper side of the base 20, and comprising a body 13 and an indicator needle 14. Is installed on the lower side of the support 20, the body 13 of the indicator 12 is fixed to the lower side of the support 20, the indicator needle 14 is formed on the lower end of the measuring plate 11 The measuring tool 18 inserted into the needle inserting groove 17 so that its tip points to the center portion of the scale and the measuring tool 18 inserted into the measuring tool inserting groove 16 of the measuring plate 11 is It should be located at left and right respectively.
이때에도 측정구(18)의 측정침(19)은 상기 지시침(14)의 선단과 같이 눈금을 지시하도록 설치한다.At this time, the measuring needle 19 of the measuring tool 18 is installed so as to indicate the scale like the tip of the indicator needle 14.
상기와 같이 측정계를 설치하면 측정판(11)에 형성한 명판(15)에 제작자, 설치년월, 용량, 설치위치, 설치온도, 설계신축량 등 기타 필요사항을 기록한다.When the measurement system is installed as described above, other requirements such as the manufacturer, the installation date, the capacity, the installation location, the installation temperature, the design stretch amount, etc. are recorded on the name plate 15 formed on the measurement plate 11.
상기와 같이 하여 측정계의 설치가 완료되면, 기후조건, 교통량 등에 의해 교량의 상부구조가 신축될 때 상기 교량의 상부구조가 신축됨에 따라 이 상부구조와 연결된 받침(20)의 상측도 좌측 또는 우측으로 이동된다.When the installation of the measuring system is completed as described above, when the upper structure of the bridge is stretched due to climatic conditions, traffic volume, etc., the upper side of the bridge 20 connected to the upper structure is stretched to the left or right as the upper structure of the bridge is stretched. Is moved.
상기와 같이 받침(20)의 하측은 고정된 상태에서 상측이 움직이게 되므로, 상측에 설치한 측정판(11)도 상측의 움직임에 따라 움직이는데, 지시계(12)는 하측에 설치되었기 때문에 고정된 상태로 있게 된다.As described above, the lower side of the support 20 moves in the fixed state, so that the measuring plate 11 installed on the upper side moves according to the movement of the upper side, but the indicator 12 is fixed because it is installed at the lower side. Will be.
따라서, 지시계(12)의 지시침(14)는 고정된 상태로 있으나, 측정판(11)이 움직이므로, 상기 지시침(14)이 측정판(11)에 인쇄된 눈금의 중앙부분을 지시하던 상태가 변하게 되어 눈금의 중앙으로부터 좌측 또는 우측을 지시하게 된다.Therefore, although the indicator needle 14 of the indicator 12 is fixed, the measurement plate 11 is moved, so that the indicator needle 14 indicates the center portion of the scale printed on the measurement plate 11. The state changes to point left or right from the center of the scale.
즉, 받침(20)의 상측이 좌측으로 이동하면 지시침(14)은 눈금의 중앙으로부터 우측에 위치하게 되며, 상기 받침(20)의 상측이 우측으로 이동하면 지시침(14)은 눈금의 중앙으로부터 좌측에 위치하게 되는 것이다.That is, when the upper side of the base 20 moves to the left side, the indicator needle 14 is located at the right side from the center of the scale. When the upper side of the base 20 moves to the right side, the indicator needle 14 is at the center of the scale. It is located on the left side from.
상기와 같이 받침(20)의 상측이 움직이게 되어 지시침(14)이 지시하는 눈금의 위치가 변하게 되는데, 이 과정에서 지시침(14)의 양측에 각각 설치한 측정구(18)도 지시침(14)에 의해 그 위치가 변하게 된다.As described above, the upper side of the support 20 is moved to change the position of the scale indicated by the indicator needle 14. In this process, the measuring spheres 18 installed on both sides of the indicator needle 14 are also indicated by the indicator needle ( 14) the position is changed.
이를 더욱 상세히 설명하면 받침(20)이 좌측 또는 우측으로 움직이면 이 받침(20)에 설치한 측정판(11)과 상기 측정판(11)의 하단에 형성한 측정구 삽입홈 (16)에 삽입 설치된 측정구(18)가 받침(20)의 상측과 동일하게 움직이게 되는데, 받침(20)의 상측이 어느 정도 움직이면 측정구(18)는 지시침(14)에 걸려 더 이상 받침(20)의 상측과 같이 움직이지 못하게 된다.To explain this in more detail, when the support 20 moves to the left or right side, the measuring plate 11 installed in the support 20 and the measuring tool insertion groove 16 formed at the lower end of the measuring plate 11 are installed. Measuring sphere 18 is moved in the same way as the upper side of the base 20, if the upper side of the base 20 is moved to some extent measuring sphere 18 is caught by the indicator needle 14 and the upper side of the base 20 is no longer You can't move together.
이 상태에서 받침(20)의 상측이 더욱 더 움직이면 지시침(14)은 눈금의 중앙으로부터 좌측 또는 우측으로 더욱 더 멀어지게 되는데, 이때 측정구(18)는 지시침(14)에 걸린 상태이기 때문에 지시침(14)에 밀리며 원래 위치에서 외측으로 이동(실상은 제 위치에서 고정된 상태로 있고 측정판(11)이 이동하는 것이나, 설명의 편의상 측정구(18)가 이동하는 것으로 설명함)하며 그 위치가 변하게 된다.In this state, when the upper side of the support 20 moves further, the indicator needle 14 is further moved to the left or right from the center of the scale, since the measuring tool 18 is caught by the indicator needle 14. Pushed by the indicator hand 14 and moved outward from the original position (actually, it is fixed in place and the measuring plate 11 is moved, but for convenience of explanation, the measuring tool 18 is described as moving) The position will change.
이후 받침(20)의 상측이 원래 상태로 복귀되면 지시침(14)은 다시 눈금의 중앙을 지시하게 되나, 측정구(18)는 원래 위치로 되돌아 오지 못하고 외측으로 이동된 곳에 있게되며, 이 위치에서 측정구(18)의 측정침(19)이 지시하는 눈금을 읽은 값이 교량이 신축되는 최대의 값이 되는 것이다.Then, when the upper side of the support 20 is returned to its original state, the indicator needle 14 again points to the center of the scale, but the measuring sphere 18 is not returned to its original position but is moved to the outside. The reading of the scale indicated by the measuring needle 19 of the measuring tool 18 becomes the maximum value at which the bridge is stretched.
상기와 같이 측정구(18)는 지시침(14)에 의해 외측으로 밀리기는 하나, 내측으로는 이동되지 못하기 때문에 항상 받침(20)의 상측이 움직이는 최대 또는 최소치를 나타낼 수 있으며, 이 값이 교량 신축의 최대값이 되는 것이다.As described above, since the measuring tool 18 is pushed outward by the indicator needle 14 but cannot be moved inward, the measuring tool 18 may always indicate the maximum or minimum value at which the upper side of the support 20 moves. It is the maximum value of the bridge construction.
따라서 교량의 점검시 상기 측정구(18)의 측정침(19)이 지시하는 눈금의 값을 읽어 기록한 후, 측정구(18)를 인위적으로 원래 위치로 복귀시키면 상기와 같은 작용에 의해 다시 외측으로 이동하게 되고, 다음 점검때 또 다른 값을 기록할 수 있는 것이며, 제작자, 설치년월, 용량, 설치위치, 설치온도, 설계신축량 등을 현장에서 즉시 확인할 수 있는 것이다.Therefore, in the inspection of the bridge, after reading and recording the value of the scale indicated by the measuring needle 19 of the measuring tool 18, if the measuring tool 18 is artificially returned to its original position, it is moved to the outside again by the above-described action. It is possible to move and to record another value at the next inspection, and to immediately check the manufacturer, the year and month of installation, capacity, installation location, installation temperature, design stretch and so on.
한편, 첨부한 도면 도 3 내지 도 4에 도시한 본 발명의 다른 실시예는 본 발명의 실시예에서의 측정구(18) 위치를 변경한 것이고, 지시침(14)이 측정구(18a)의 돌기(18b)를 이동시킨다는 것 외에 나머지는 본 발명과 그 작용이 동일하므로, 구체적인 설명은 생략한다.Meanwhile, another embodiment of the present invention shown in FIGS. 3 to 4 is to change the position of the measuring sphere 18 in the embodiment of the present invention, the indicator needle 14 is Except for moving the projection 18b, the rest is the same as the present invention, the detailed description thereof will be omitted.
