Description

도로구조물의 신축이음장치 및 그 설치방법{The expansion joint apparatus of road structure, and the installing method}Expansion joint apparatus of road structure, and the installing method

본 발명은 교량의 상판 연결부, 지하차도 연결부 및 하천복개 구조물의 연결부 등과 같은 도로구조물의 연결부를 실링재로 포장할 때 온도변화에 따른 도로구조물의 가변량에 의해 실링제의 부피변화를 보상하는 신축판을 설치하므로써 항상 실링제의 표면이 노면과 수평을 유지하도록 하는 도로구조물의 신축이음장치 및 그 설치방법에 관한 것이다.The present invention is a new construction to compensate for the volume change of the sealant by the variable amount of the road structure according to the temperature change when paving the connection portion of the road structure, such as the top plate connection of the bridge, the connection of the underground driveway and the connection of the stream cover structure with the sealing material The present invention relates to an expansion joint device for a road structure and a method of installing the same so that the surface of the sealant is always horizontal with the road surface by installing the ss.

일반적으로 교량의 상판연결부, 지하차도 연결부, 하천복개 구조물 등(이하 도로구조물 연결부라함)과 같은 연결부를 포장할 때에는 신축이음장치를 설치한 후 그 위에 아스팔트 포장재를 포장한다.In general, when paving connections such as bridge tops, underground driveway connections, river cover structures, etc. (hereinafter referred to as road structure connections), the asphalt pavement is paved after installing expansion joints.

도로구조물은 온도에 따라 신축되어 그 연결부의 간격이 가변되므로 도로구조물의 사이에는 충분한 유간을 확보한다. 즉, 여름과 같이 고온에서는 신장되어 연결부의 간격이 좁아지고 또 겨울과 같이 저온일 때에는 도로구조물이 수축하기 때문에 간격이 넓어지게 됨으로 이 작용이 원활히 일어날 수 있도록 유간을 확보하는 것이다.The road structure is stretched according to the temperature so that the gap of the connecting portion is variable, thereby ensuring sufficient clearance between the road structures. In other words, it is extended at high temperatures such as summer to narrow the gap between the connecting portion, and at low temperatures such as winter, the road structure is contracted so that the gap is widened so that the gap can be smoothly generated.

도 1a,1b는 종래의 기술에 따른 도로 또는 교량의 연결부 포장상태도이다.Figure 1a, 1b is a state diagram paved road or bridge connection according to the prior art.

종래에는 이러한 도로구조물의 연결부를 실링할 때에는 단순히 실링제(12)를 이용하여 포장하게 된다.Conventionally, when sealing the connection portion of the road structure is simply paved using a sealing agent (12).

이 때문에 여름과 같이 기온이 올라가 도로구조물이 신장되게 되면 연결부의 간격이 좁아지게 되고 그 사이에 충진된 실링제(12)가 도 1a와 같이 상부로 부풀어올라 둔턱이 생기게 될 뿐만 아니라 차량의 진행 방향에 따라 실링제(12)가 한쪽으로 쏠려 골이 파여지는 현상이 발생됨으로 차량의 통행에 큰장애물로 작용하게 된다.For this reason, when the temperature rises, as in summer, the road structure is extended, the gap between the connecting parts becomes narrow, and the sealing agent 12 filled therebetween swells upward as shown in FIG. As the sealant 12 is pulled to one side, a phenomenon in which the bone is dug is generated, which acts as a large obstacle to the traffic of the vehicle.

또 겨울과 같이 기온이 내려가게 되면 연결부의 간격이 넓어지게 되어 실링제(12)는 도 1b와 같이 넓어진 용적의 공간으로 분산되기 때문에 여름과는 반대로 오목한 요홈이 발생되어 역시 차량의 통행에 장애물로 작용하게 되는 단점이 있었다. 이러한 현상에 의해 연결부의 상태에 따라 수시로 도로의 유지보수작업을 수행해야 하기 때문에 많은 인력과 시간 및 비용이 낭비되는 폐단이 있었다.In addition, when the temperature decreases, such as winter, the gap between the connecting parts becomes wider, and the sealing agent 12 is dispersed in the space of the enlarged volume as shown in FIG. There was a downside to working. Due to this phenomenon, the maintenance of the road must be performed from time to time depending on the condition of the connection, which was a waste of a lot of manpower, time and money.

본 발명은 이러한 종래의 단점을 해소하기 위해 창안한 것으로서, 그 목적은 교량의 상판 연결부, 지하차도 연결부 및 하천복개 구조물의 연결부 등과 같은 도로구조물의 연결부를 실링재로 포장할 때 온도에 따라 가변되는 도로의 포장재 또는 교량의 상판의 신축작용에 관계없이 연결부에 충진된 실링제의 표면이 항상 노면과 수평을 이루도록 하여 차량통행을 원활히 함과 아울러 빈번한 도로유지보수공사를 실시하지 않아도 되므로 많은 인력 및 비용이 절감할 수 있는 도로구조물의 신축이음장치 및 그 설치방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above disadvantages, the object of the road is to vary the temperature when paving the connection of the road structure, such as the connection of the top plate of the bridge, the connection of the underground roadway and the connection of the stream covering structure with a sealing material Regardless of the expansion or contraction of the pavement of the bridge or the top of the bridge, the surface of the sealing material filled in the connecting part is always horizontal to the road surface, so that the vehicle can pass smoothly and frequent road maintenance work is not necessary. It is an object of the present invention to provide an expansion joint device and a method of installing the road structure that can be reduced.

상기 목적을 달성하기 위한 본 발명의 수단은, 교량의 상판 연결부, 지하차도 연결부 및 하천복개 구조물의 연결부 등과 같은 도로구조물의 연결부를 실링재로 포장함에 있어서,Means of the present invention for achieving the above object, in the packaging of the connecting portion of the road structure, such as the connection of the upper plate connection of the bridge, the connection of the underground roadway and the stream covering structure with a sealing material,

양측에 수평한 날개판을 갖고 그 사이에 두 개의 절첩판을 각각 힌지로 연결시켜 3절의 신축판을 구비하여 양측 절첩판의 중앙부가 임의의 간격으로 절첩된 상태를 이루게 하면서 양측 날개판은 수평하게 펼쳐 분리된 양측 도로구조물에 앵커볼트로 고정한 후 그 상부에 실링제를 충진시켜 연결부를 포장하여 온도에 따라 신축 가변되는 교량 상판 및 도로포장재의 신축정도에 따라 그 용적을 달리하도록 하여 연결부를 포장하는 실링제가 도로의 노면과 수평을 유지하도록 하여 달성된다.Both wing plates have horizontal wing plates on both sides, and two folding plates are hinged between them, and three extension plates are provided so that the center portions of both folding plates are folded at random intervals while the wing plates are horizontally arranged. After fixing the anchor bolts on both sides of the separated and separated road structure, the sealing part is filled in the upper part and the connection part is packed. This is achieved by keeping the sealant level with the road surface.

이하, 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 신축이음장치가 설치된 도로 연결구조물 단면도이고, 도 3은 본 발명에 따른 신축이음장치의 분리사시도이며, 도 4는 본 발명에 따른 신축판의 설치상태 사시도이다.Figure 2 is a cross-sectional view of the road connecting structure installed expansion joint according to the invention, Figure 3 is an exploded perspective view of the expansion joint according to the present invention, Figure 4 is a perspective view of the installation state of the expansion plate according to the present invention.

도시된 도면은 교량의 상판 연결부, 지하차도 연결부 및 하천복개 구조물의 연결부 등과 같은 도로구조물의 연결부를 연결한 신축이음부를 도시한 것으로서, 참조번호 10a,10b는 이러한 연결부를 이루는 도로구조물이며 그 상부에는 아스팔트 포장재(11)가 포장되어 있다.The illustrated figure shows expansion joints connecting road structures, such as the top plate connection of the bridge, the connection of the underground roadway and the connection of the stream cover structure, wherein reference numerals 10a and 10b denote road structures that form these connections and the upper portions thereof. Asphalt pavement 11 is packed.

도로구조물(10a)(10b)과 구조물의 사이에는 온도에 따라 도로구조물(10a)(10b)의 신축량을 예상하여 유간을 확보하며, 그 유간 사이에는 신축판(20)이 설치된다.Between the road structures 10a, 10b and the structure in accordance with the temperature to predict the amount of expansion of the road structures (10a, 10b) to secure the clearance, between the clearance between the expansion plate 20 is installed.

신축판(20)은 4개의 판 즉, 두 개의 양측 날개판(21a)(21b)과 그 사이에 두 개의 절첩판(23a)(23b)으로 구성된다. 각 날개판(21a)(21b)과 절첩판(23a)(23b)은 힌지(24a)(24b)(24c)결합되어 자유로이 절첩되게 연결된다. 즉, 일측판의 연결부에는 일정한 간격으로 돌출편을 형성하고 이와 연결되는 타측판의 대향에는 엇갈리는 위치로 돌출편을 형성함과 동시에 각각의 돌출편을 말아 핀구멍을 형성한 다음 그 핀구멍에 힌지핀을 끼워 절첩되도록 되어 있다.The expansion and contraction plate 20 is composed of four plates, that is, two wing plates 21a and 21b and two folding plates 23a and 23b therebetween. Each of the wing plates 21a, 21b and the folding plates 23a, 23b are hinged 24a, 24b, 24c, and are freely connected to each other. That is, protrusions are formed at regular intervals in the connecting portion of one side plate, and protrusions are formed at staggered positions on opposite sides of the other side plate connected thereto, and at the same time, each pin is rolled to form a pin hole, and then hinged at the pin hole. It is made to be folded by pin.

또 이와 같은 구조로 된 신축판(20)의 양 날개판(21a)(21b)에는 볼트구멍(22)이 일정한 간격으로 다수개 천공되어 있다.In addition, a plurality of bolt holes 22 are perforated at regular intervals in both wing plates 21a and 21b of the expansion and contraction plate 20 having such a structure.

신축판(20)은 설치시 양측 도로구조물(10a)(10b)의 상부에 양측 날개판(21a)(21b)을 각각 안착시킨 후 볼트구멍(22)으로 앵커볼트(40)를 도로구조물(10a)(10b)에 박아 도 4와 같이 고정시킨다. 앵커볼트(40)의 상부에는 다수개의 플랜지(41)를 구비하여 설치후 실링제(12)와 결착력을 높일 수 있도록 되어 있다. 참조번호 42는 앵커핀이다.The expansion and contraction plate 20 has both the wing plates 21a and 21b respectively seated on top of both road structures 10a and 10b at the time of installation, and then anchor bolts 40 to the road structures 10a by bolt holes 22. ) 10b, and fix it as shown in FIG. The upper part of the anchor bolt 40 is provided with a plurality of flanges (41) to increase the binding force with the sealing agent 12 after installation. Reference numeral 42 is an anchor pin.

설치된 신축판(20)의 상부로 실링제(12)를 충진시켜 포장한다. 포장시 적정두께로 실링제(12)를 부분 충진시키고 그위에 밀림방지판(30)을 수평하게 설치한 후 다시 실링제(12)를 완전히 충진시켜 포장한다. 도시된 바와 같이 밀림방지판(30)에는 다수개의 구멍(31)이 천공되어 있기 때문에 밀림방지판(30)의 실링제(12)와 그 상부의 실링제(12)가 서로 연결되어 도 2와 같이 상하 견고한 결착력을 갖다.The sealing agent 12 is filled in the upper part of the installed stretchable plate 20, and packed. When packing, the sealing agent 12 is partially filled to an appropriate thickness, and the anti-rolling plate 30 is horizontally installed thereon, and then the sealing agent 12 is completely filled and packed. As shown in FIG. 2, since the plurality of holes 31 are drilled in the anti-rolling plate 30, the sealing agent 12 and the upper sealing agent 12 of the anti-rolling plate 30 are connected to each other. It has strong binding force up and down together.

한편, 신축판(20)을 설치할 때 날개판(21a)(21b) 사이의 절첩판(23a)(23b)은 하부로 일정한 각도를 갖도록 절첩시키게 되는데, 절첩판(23a)(23b)이 이루는 각은 절첩판(23a)(23b)사이의 공간 용적을 결정하는 요인이 된다.On the other hand, when the expansion plate 20 is installed, the folding plate (23a, 23b) between the wing plate (21a) (21b) is to be folded to have a constant angle to the bottom, the angle formed by the folding plate (23a, 23b) Is a factor that determines the volume of space between the folded plates 23a and 23b.

이러한 구조의 절첩판(23a)(23b)에 의해 도로구조물(10a)(10b) 및 실링제(12)의 가변량을 보상하므로써 실링제(12)의 표면은 도로의 표면과 수평을 이루게 된다.By compensating for the variable amounts of the road structures 10a and 10b and the sealing agent 12 by the folding plates 23a and 23b of this structure, the surface of the sealing agent 12 is made horizontal with the surface of the road.

절첩판(23a)(23b)의 각도는 구조물의 신축정도와 연평균 최고기온이었을 때의 도로구조물(10a)(10b) 신축량을 예상하여 각도를 조절한다.The angles of the folding plates 23a and 23b are adjusted in anticipation of the amount of expansion and contraction of the structure and the amount of expansion and contraction of the road structures 10a and 10b when the annual average maximum temperature is obtained.

이는 연중 온도가 가장 높았을 때 도로구조물(10a)(10b)의 신장량이 가장 많고 또 실링제(12)의 상하 부풀림 정도가 가장 클 것이기 때문에 이때를 기준으로 설정한다. 절첩판의 용적이 가장크게 나타나는 각은 절첩판간의 각이 직각을 이룰 때이다. 따라서 실링제의 상하 부풀림정도가 가장큰 시점에서 절첩판(23a)(23b)의 각도가 직각을 이루도록 한다.This is set based on this time, since the elongation of the road structures 10a and 10b is the largest and the degree of swelling of the sealant 12 is the largest when the temperature is highest during the year. The angle at which the volume of the folding plates is greatest is when the angle between the folding plates is at right angles. Therefore, the angles of the folding plates 23a and 23b form a right angle at the time when the degree of inflation of the sealing agent is greatest.

이러한 구조의 본 발명은 여름과 같이 온도가 높아 도로구조물(10a)(10b)이 신장되게 되면 연결부의 간격이 좁아지게 되고 그 내부에 충진된 실링제(12)가 압축되어 부풀어오르게 된다. 이때 신축판(20)의 절첩판(23a)(23b)이 직각에 가까운 각도로 좁아지기 때문에 결국 용적이 점점 커지게 된다. 이 때문에 상부로 부풀어오르는 양만큼의 실링제(12)가 절첩판(23a)(23b)의 늘어난 용적내로 수용되어 실링제(12)의 상면은 더 이상 부풀어오르지 않아 도로의 상면과 실링제(12)의 상면은 수평을 이루게 된다.According to the present invention, as the summer temperature increases, the road structures 10a and 10b are extended so that the gap between the connecting portions is narrowed and the sealing agent 12 filled therein is compressed and swelled. At this time, since the folding plates 23a and 23b of the expansion and contraction plate 20 are narrowed at an angle close to the right angle, the volume eventually increases. For this reason, the amount of the sealing agent 12 swelling upward is accommodated in the increased volume of the folding plates 23a and 23b so that the upper surface of the sealing agent 12 no longer swells, so that the upper surface of the roadway and the sealing agent 12 The top surface of) is horizontal.

반면, 겨울과 같이 주위 온도가 낮아 도로구조물(10a)(10b)이 수축하게 되면 연결부의 간격이 넓어지게 되어 실링제(12) 또한 넓게 펼쳐지게 된다. 이때 신축판(20)의 절첩판(23a)(23b)이 펼쳐져 용적이 점점 작아지게 된다. 이 작동에 의해 절첩판(23a)(23b)의 접힘용적내에 수용되어 있던 실링제(12)가 상부로 상승하게 되어 결국 간격이 늘어난 연결부내의 실링제(12)를 보충해주기 때문에 도로의 상면과 실링제(12)의 상면은 수평을 유지하게 된다.On the other hand, when the road structure (10a, 10b) shrinks because the ambient temperature is low, such as winter, the gap between the connection is widened and the sealing agent 12 is also widely spread. At this time, the folding plates 23a and 23b of the expansion and contraction plate 20 are unfolded and the volume becomes smaller. By this operation, the sealing agent 12 accommodated in the folding volume of the folding plates 23a and 23b rises to the upper part, and eventually replenishes the sealing agent 12 in the connection part with the space | interval increased, so that the upper surface and sealing of the roadway are sealed. The upper surface of the twelfth is kept horizontal.

또한 실링제(12)의 내부에 설치된 밀림방지판(30)은 실링제(12)를 보강해주는 작용을 하기 때문에 도로를 주행하는 차량등의 동하중의 작용에 의해 실링제(12)가 일측으로 밀리게 되는 현상을 효과적으로 방지할 수가 있다. 또 상하부로 천공된 다수개의 구멍(31)으로 상하 실링제(12)가 결착되어 있기 때문에 실링제(12)의 포장상태를 견고하게 유지할 수가 있다.In addition, since the anti-rolling plate 30 installed inside the sealing agent 12 acts to reinforce the sealing agent 12, the sealing agent 12 is pushed to one side by the action of dynamic loads such as a vehicle traveling on the road. Can be effectively prevented. In addition, since the upper and lower sealing agent 12 is bound by a plurality of holes 31 drilled in the upper and lower parts, the packing state of the sealing agent 12 can be maintained firmly.

도 5는 본 발명의 일실시예에 따른 신축이음장치 설치상태도이다.Figure 5 is a state installation installation expansion joint according to an embodiment of the present invention.

도시된 신축이음장치는 신축판(20)을 도로구조물(10a)(10b)에 결합시킬 때 별도의 앵커볼트(40)를 사용하지 않고 설치할 수 있도록 한 것으로서, 도로구조물(10a)(10b)의 대향단부에 설치된 철근중 주근(50)의 둘레를 연결하는 늑근(51)의 일단을 상부로 노출시켜 그 단부에 나사부를 형성하고 이에 신축판(20)을 결합시킨 후 너트(52)를 체결하여 결합시키도록 되어 있다.The illustrated expansion joint device is to be installed without using a separate anchor bolt 40 when the expansion plate 20 is coupled to the road structure (10a) (10b), of the road structure (10a) (10b) Exposed one end of the frame 51 connecting the periphery of the main bar 50 of the reinforcing bar installed on the opposite end to form a screw portion at the end thereof, and the expansion and contraction plate 20 is coupled to the nut 52 and then fastened It is intended to be combined.

이와 같이 하면 종래와 같이 앵커볼트를 박기 위해 구멍을 뚫거나 앵커볼트(40)를 박는 번거로운 작업이 필요 없기 때문에 부품과 시공시간 및 시공비 절감의 효과가 있으며, 특히 콘크리트에 매설된 철근에 결합되기 때문에 더욱더 견고하게 설치할 수가 있다.This eliminates the cumbersome work of drilling holes or anchoring the anchor bolts 40 to drive anchor bolts as in the prior art, thereby reducing parts, construction time, and construction costs, especially since they are coupled to reinforcement embedded in concrete. It can be installed firmly.

이상에서 살펴본 바와 같이 본 발명은 교량의 상판 연결부, 지하차도 연결부 및 하천복개 구조물의 연결부 등과 같은 도로구조물의 연결부를 실링제로 포장할 때 온도에 따라 신축되는 도로구조물 사이에 실링제를 수용하는 신축판을 설치하여 실링제의 가변량을 보상하도록 되어 있으므로 실링제의 표면이 항상 노면의 상면과 수평을 이루게 되는 효과가 있다. 이 효과로 인하여 승차감을 향상시키는 등 원활한 차량통행을 이룰 수 있고 빈번한 도로유지보수공사를 실시하지 않아도 되므로 많은 인력 및 비용이 절감할 수 있는 효과가 있다.As described above, in the present invention, when a connection portion of a road structure such as a top plate connection part of a bridge, an underground road connection part, and a connection part of a stream covering structure is packed with a sealing agent, a new plate containing a sealing agent between road structures that are stretched according to temperature Since it is to compensate for the variable amount of the sealant by installing the effect of the surface of the sealant is always horizontal to the upper surface of the road surface.
