본 고안은 토목공사용 부재 예를들면 시일드 세그먼트, 맨홀 및 컬버트 박스(culvert box)등의 콘크리드 2차제품의 접합면 기타 이음새를 방수 처리하기 위하여 사용하는 이음새의 방수구조에 관한 것이다.The present invention relates to a waterproof structure of seams used for waterproofing joint surfaces and other seams of concrete secondary products such as shield segments, manholes and culvert boxes.
종래에는 예를들어 시가지 지하에 굴삭하는 시일드 터널의 공사재료에는 제1도 및 제2도에 도시한 바와 같이 터널의 부분 내벽면을 구성하는 콘크리드재의 유니트화된 다수의 세그먼트(1)가 사용되어서 터널시공시에는 이들의 각 세그먼트(1)는 갱도의 주벽둘레(a) 및 갱도의 길이방향(b)의 양방향을 따라 밀접하게 이어붙여져 결합되어 있다.Conventionally, for example, in the construction material of a shield tunnel excavated underground, a large number of unitized segments 1 of concrete material constituting a partial inner wall surface of the tunnel are shown in FIGS. 1 and 2. In the case of tunnel construction, each segment 1 thereof is closely connected and joined along both directions of the main wall circumference a of the tunnel and the longitudinal direction b of the tunnel.
이와 같이하여 각 세그먼트(10)의 판면의 4방 둘레에는 주벽둘레(a)에 따른 전후의 플랜지(2), (3)와 길이방향(b)에 따른 상하의 플랜지(4), (5)가 틀형으로 성형되어서 이들의 세그먼트(1)가 서로 결합된 때에는 상호 인접하는 플랜지(2)와 플랜지(3) 및 플랜지(4)와 플랜지(5)를 각각 겹쳐지게한 다음에 결합 보울트(6)에 의해 조여붙여 결합되어 있다.In this manner, the four circumferences of the plate surface of each segment 10 have the front and rear flanges 2 and 3 along the circumferential wall circumference a, and the upper and lower flanges 4 and 5 along the longitudinal direction b. When the segments 1 are joined to each other by being molded in a frame shape, the adjacent flanges 2 and 3, and the flanges 4 and 5, respectively, overlap each other, and then the joining bolts 6 Tighten together and join.
여기에 있어서, 갱도 부근에서의 샘물이 갱도내로 누수하는 것을 방지하기 위하여 서로 겹쳐진 플랜지의 각 접합면의 이음새를 방수처리하는 것이 필요한 것이므로 서로 인접될 플랜지면 사이의 틈새(이음새)(7)에 대면하는 플랜지면의 적어도 한쪽에는 띠형상의 시일재(8)가 그 한외벽면인 첩부면이 대향하는 적어도 한쪽의 플랜지면에 접착 고정되어 있다.In this case, it is necessary to waterproof the joints of the joint surfaces of the flanges overlapped with each other in order to prevent leakage of spring water near the tunnels into the tunnels. The strip | belt-shaped sealing material 8 is adhesively fixed to at least one flange surface which the sticking surface which is the outer wall surface opposes at least one of the flange surfaces.
그런데, 종래의 상기 시일재(8)로서는 공지의 수팽창성 재료, 예를들어 고흡수성 수지와 합성고무가 혼합성형 가황하여 되는 재료가 사용되는 것이 있으며, 동 시일재(8)는 이 재료에 의해 단층 성형된 것이고, 이와 같이하여 이 시일재(8)의 작용은 틈새(7)으로의 침수(W)의 침적에 의해 시일재(8)가 팽창하여 틈새(7)를 수밀하게 폐쇄하는 역할을 하고 있다.By the way, as the conventional sealing material 8, a known water-expandable material, for example, a material in which the superabsorbent resin and the synthetic rubber are mixed and vulcanized is used, and the sealing material 8 is made of this material. In this way, the action of the seal material 8 serves to close the gap 7 tightly by expanding the seal material 8 by the deposition of the immersion W into the gap 7. Doing.
그러나, 이와 같은 수팽창성 재료의 단층성형에 의한 종래의 단체형의 시일재(8)를 사용할 경우에는 수팽창성 통상의 비팽창성 고무에 비해 약하고 탄성의 점으로도 떨어지는 재료이기 때문에 종래 시일재(8)에 의해 이 시일재의 흡수팽창전 소위 초기방수를 완전하게 하기 위해서는 시일재(8)를 두껍게 형성시킬 필요가 있었으나, 재료비가 상승할 뿐만 아니라 운반작업시등에 시일재(8)의 돌출면이 다른 부재와 충돌하여 세그먼트(1)의 플랜지(4)의 접착면으로 부터 떨어지는 사고가 많다.However, in the case of using the conventional single-shaped sealing material 8 by the single layer molding of the water-expandable material, the conventional sealing material 8 is weaker than the water-expandable ordinary non-expandable rubber and is also inferior in elasticity. In order to complete the so-called initial waterproofing before the expansion and expansion of the sealant material, it is necessary to form the sealant material thicker. However, not only the material cost increases but also the protruding surface of the sealant material 8 is different during transportation. Many accidents collide with the member and fall from the adhesive surface of the flange 4 of the segment 1.
또 침수(W)에 의해 시일재(8)가 팽창하면 시일재(8)는 더욱 약해지며, 그 팽창은 3차원 방향으로 팽창하는 특성을 가지고 있고, 특히 옆방향의 인접하는 세그먼트(1)의 틈새(7) 내와 길이방향으로 연속하는 시일재(8)의 연결단면의 틈새방향으로 크게 팽창한다. 따라서 인접하는 세그먼트(1)의 위치가 진동등에 의해 그 위치가 변하면 상기 팽창된 시일재의 부분이 찢어지거나 혹은 금이가서 깨어지며 결국에는 시일재(8)와 플랜지(4)의 벽면사이의 첩부면이 박리하여 시일재(8)가 떨어져 나가는 문제가 있었다.In addition, when the sealing member 8 expands due to immersion W, the sealing member 8 becomes weaker, and the expansion member has a characteristic of expanding in three-dimensional direction, and in particular, of adjacent segments 1 in the lateral direction. It expands greatly in the gap direction of the connection cross section of the sealing material 8 continuous in the clearance gap 7 and the longitudinal direction. Therefore, when the position of the adjacent segment 1 changes its position due to vibration or the like, the portion of the expanded sealing member is torn or cracked and eventually breaks, and eventually the bonding surface between the sealing member 8 and the wall surface of the flange 4 is broken. This peeling caused a problem that the sealing material 8 fell off.
이와 같은 종래의 상기 시일재(8)(제2도)의 곤란점을 방지하여 시일재의 구조로서, 본 고안자는 수팽창성 재료와 비팽창고무와의 복합구조를 가진 제3도 (a), (b)의 복합형 시일재(9)를 제안하여 여러가지 실험연구를 하여 왔다.As a structure of the sealing material by preventing the difficulty of the conventional sealing material 8 (FIG. 2), the inventors have shown that FIG. 3 (a), (a) having a composite structure of the water-expandable material and the non-expandable rubber. b) The composite sealing material 9 was proposed and various experimental studies have been conducted.
이 기제안에 따르는 시일재(9)는 중앙부의 수팽창성 재료로되는 띠형상의 팽창부분(10)의 양측면에 비팽창성 고무로 되는 비팽창부분(11), (11)이 설치되는 구조이다. 이 시일재(9)를 틈새(7)에 사용하였을 경우, 이 틈새(7)가 제3도(a)의 상태로 부터 제3도(b)의 상태로 변화하여 넓어졌을 경우 초기의 제3도 (a)의 상태에서는 물은 비팽창성 부분(11)에만 접촉하고 팽창부분(10)에 물이 들어가서 팽창부분(10)이 흡수 팽창하여 방수하기 까지에는 일정한 시간이 필요하게 된다. 이 때문에 틈새 변동의 초기에 누수가 되기 쉬운 문제점이 있다. 또 중간부의 팽창부분(10)이 흡수 팽창하는 것으로 양측의 비팽창부분(11), (11)을 폭방향으로 압동시키는 것이므로 길이방향에 비교하여 폭방향의 규제가 약하고 또, 저면의 첩부면이 상기 팽창시에는 분리되기 쉬운 문제점도 있다.The sealing material 9 according to the present invention is a structure in which the non-expandable portions 11 and 11 made of non-expandable rubber are provided on both sides of the band-shaped expansion portion 10 made of the water-expandable material in the center portion. When this sealing material 9 is used for the gap 7, the gap 7 changes from the state of FIG. 3 (a) to the state of FIG. In the state of FIG. (A), the water contacts only the non-expandable portion 11 and the water enters the expanded portion 10 so that a certain time is required until the expanded portion 10 is absorbed, expanded and waterproof. For this reason, there exists a problem which becomes easy to leak at the beginning of gap variation. Moreover, since the expansion part 10 of the middle part absorbs and expands, it pushes the non-expansion parts 11 and 11 on both sides in the width direction, so that the restriction in the width direction is weak compared to the longitudinal direction, There is also a problem that is easy to separate during the expansion.
본 고안은 이상의 문제점을 감안하여 되어진 것으로 즉, 본 고안의 목적은 종래의 수팽창성 재료의 단층성형에 의한 단체형 시일재의 최대결점인 3차원방향으로의 팽창을 개량하여 방향규제를 하는 것에 의하여 유효한 방수성이 얻어지고, 또 첩부면에서의 접착강도를 향상시키는 동시에 이 첩부면에서의 방수성도 향상시키고, 또한 이음새에서의 틈새가 벌어지는데 따르는 방수성을 향상시키도록한 복합형 시일재를 사용한 이음새의 방수구조를 제공하는데 있다.The present invention has been made in view of the above problems, that is, the object of the present invention is effective by improving the expansion in the three-dimensional direction, which is the biggest drawback of the single seal material by the single-layer molding of the conventional water-expandable material. Waterproof structure of the seam using a composite sealant which achieves waterproofness and improves the adhesive strength on the surface of the patch, and also improves the waterproofness on the surface of the patch, and also improves the waterproofness caused by gaps in the seams. To provide.
다음에 본 발명의 구성을 그 하나의 실시예에 대응하는 제4도 및 제5도 (a), (b)를 참조하여 설명한다.Next, the configuration of the present invention will be described with reference to FIGS. 4 and 5 (a) and (b) corresponding to one embodiment.
즉 본 고안은 이음새의 대향벽면(4), (5) 사이에 시일재(12-1)가 그 한외벽면인 첩부면(12-1a)이 상기 이음새의 대향벽면의 적어도 한쪽면에 접착되어 배치되어 있는 이음새의 방수구조에 있어서, 상기 시일재(12-1)는 수분을 흡수하는 것에 의해 체적이 팽창하는 특성을 가진 수팽창성 재료로 되는 팽창부분(13)과 수분에 접촉해도 실질적으로 체적이 변하지 않는 특성을 가진 비팽창성 고무로 되는 비팽창부분(14-1)이 길이방향을 따라 연속하여 중층되어서된 띠판형상을 하고 있으며, 그 비팽창부분(14-1)이 첩부면(12-1a)에 부분적으로 길이방향에 연속하여 노출되며, 그 팽창부분(13-1)이 비팽창부분(14-1)의 첩부면(12-1a)의 양측부 및 이첩부면(12-1a)과 반대측의 외측부에 배치되어진 것을 특징으로 하는 이음새의 방수구조이다.In other words, in the present invention, the sealing surface 12-1a, which is the outer wall surface of the seal member 12-1, is bonded to at least one side of the opposite wall surface of the seam between the opposing wall surfaces 4 and 5 of the seam. In the waterproof structure of the joint, the seal member 12-1 is substantially in volume even in contact with the expanded portion 13, which is a water-expandable material having the property of expanding in volume by absorbing moisture. The non-expanded portion 14-1, which is made of non-expandable rubber having a characteristic of not changing, has a strip-like shape in which the non-expanded portion 14-1 is continuously laminated in the longitudinal direction, and the non-expanded portion 14-1 is the adhered surface 12-1a. ) Is partially exposed in the longitudinal direction, and its expanded portion 13-1 is opposite to both side portions of the sticking surface 12-1a of the non-expanded portion 14-1 and to the sticking surface 12-1a. The waterproof structure of the seam, characterized in that arranged in the outer portion.
상기 본 고안의 구성에 의하면, 첩부면(12-1a)의 중앙부 부근에 비팽창부분(14-1)이 배치되어 있으므로 종래의 제2도에 도시한 단체형에서는 불가능한 팽창의 방향규제가 가능하게 되고 상하방향으로의 효과적인 동시에 모재강도의 유지등에 의하여 방수성능의 향상이 달성된다.According to the configuration of the present invention, since the non-expanded portion 14-1 is disposed near the central portion of the sticking surface 12-1a, it is possible to control the direction of expansion that is impossible in the conventional type shown in FIG. In addition, it is effective in the vertical direction and at the same time to improve the waterproof performance by maintaining the strength of the base material.
또 종래의 제3도(a), (b)의 구조에 비하여, 폭방향으로 이동하는 것과 같은 팽창의 규제를 강하게 할수 있으며, 또한 비팽창부분(14-1)이 첩부면(12-1a)의 중앙부 부근에서 부분적으로 노출하고 있는 것에 의하여 접착강도가 유지되고, 또팽창부분(13-1)도 부분적으로 첩부면(12-1a)에 노출하고 있기 때문에 접착면에서의 방수성의 확보도 가능하게 되어 밸런스를 가진 복합형 시일재에 의한 방수구조로 되었다.In addition, compared with the conventional structures of FIGS. 3A and 3B, expansion restrictions such as moving in the width direction can be strengthened, and the non-expanded portion 14-1 has a sticking surface 12-1a. The adhesive strength is maintained by partially exposing near the central portion of the surface, and the expanded portion 13-1 is also partially exposed to the sticking surface 12-1a, so that the waterproofness of the adhesive surface can be secured. The waterproof structure is achieved by a balanced composite seal material.
제4도는 일실시예에 따른 이음새의 방수구조에 사용하는 시일재(12-1)의 단면도, 제5도(a), (b)는 제4도의 방수구조의 시일작용을 설명하는 단면도이다.4 is a cross-sectional view of the seal member 12-1 used in the waterproof structure of the seam according to one embodiment, and FIGS. 5A and 5B are cross-sectional views illustrating the sealing operation of the waterproof structure in FIG.
이 시일재(12-1)의 외형은 단순한 띠판형상으로 되어 있다.The outer shape of this sealing material 12-1 is a simple strip shape.
또 첩부면(12-1a)에 노출된 비팽창부분(14-1)의 폭은 접착강도의 유지와 방수성의 확보에 관련하여, 폭의 10% 이하로 되면 충분한 접착강도의 유지가 얻어지지 않고, 폭의 90%이상으로 되면 방수성의 확보를 도모할 수 없으므로, 비팽창부분(14-1)의 총 폭은 시일재(12-1)의 폭의 10-90%, 바람직하게는 25-75%가 되도록 배치되어 있다.In addition, when the width of the non-expanded portion 14-1 exposed on the sticking surface 12-1a becomes 10% or less of the width in relation to the maintenance of the adhesive strength and the securing of waterproofness, the sufficient adhesive strength is not obtained. If the width becomes 90% or more, it is impossible to secure waterproofness. Therefore, the total width of the non-expanded portion 14-1 is 10-90% of the width of the seal member 12-1, preferably 25-75. It is arrange | positioned so that it may become%.
그리고, 비팽창부분(14-1)의 두께는 팽창의 방향규제 작용과 시일재의 팽창능력에 관련하여3%이하의 경우는 충분한 방향규제를 할수 없게 되고 70%이상으로 되면 시일재의 팽창능력 자체가 저하하여 결과적으로 효과적인 방수능력을 기대할수 없다.When the thickness of the non-expanded portion 14-1 is less than 3% in relation to the direction control action of the expansion and the expansion capacity of the seal material, sufficient direction control cannot be achieved. As a result, it is impossible to expect effective waterproofing ability.
따라서 첩부면(12-1a)에서의 비팽창부분(14-1)의 두께가 시일재(12-1) 두께의 3-70%, 바람직하게는 5-50%가 되도록 배치되어 있다.Therefore, the thickness of the non-expansion part 14-1 in the sticking surface 12-1a is arrange | positioned so that it may become 3-70%, preferably 5-50% of the thickness of the sealing material 12-1.
제5도(a), (b)에 도시한 바와 같이 이음새의 틈새가 (a)에서 (b)로 변동하였을 경우, 팽창부분(13-1)의 측면이 최초부터 물(W)과 접촉하고, 첩부면(12-1a)중앙의 비팽창부분(14-1)에 의한 규제작용에 의하여 틈새변동에 따르는 방수성도 양호하게 된다.As shown in Figs. 5 (a) and 5 (b), when the gap of the seam changes from (a) to (b), the side of the expanded portion 13-1 is in contact with the water W from the beginning. In addition, due to the regulation action by the non-expanded portion 14-1 in the center of the sticking surface 12-1a, the waterproofness due to the gap variation is also good.
또, 비팽창부분(14-1)을 첩부면(12-1a)의 일부분만으로하고 2방향을 둘러싸도록 팽창부분(13-1)을 배치하고 있으므로 시일재의 전면을 효과적으로 이용할수 있다.Moreover, since the inflation part 13-1 is arrange | positioned so that the non-expansion part 14-1 may be only a part of the sticking surface 12-1a, and encloses two directions, the whole surface of a sealing material can be utilized effectively.
또한, 상기 시일재(12-1)에 있어서 첩부면(12-1a)과 반대측면도 플랜지(5)의 벽면에 접착체에 의하여 접착되게 하여도 지장이 없다.In the seal member 12-1, the side opposite to the sticking surface 12-1a can also be bonded to the wall surface of the flange 5 by an adhesive.
제6도(a) 내지(t)는 각각 본 고안의 다른 실시예에 따르는 시일재(12-2) 내지(12-21)의 단면도이며, 13-2 내지 13-21은 팽창부분, 14-2 내지 14-21은 비팽창부분을 각각 도시한 것이다.6 (a) to (t) are cross-sectional views of the seal members 12-2 to 12-21 according to another embodiment of the present invention, respectively, and 13-2 to 13-21 are expanded portions, 14- 2 to 14-21 show unexpanded portions, respectively.
상기 각 실시예중(a), (c), (e), (g), (i), (k)의 각 시일재(12-2, 12-4, 12-6, 12-8, 12-10, 12-12, 12-21)는 그 비팽창부분(14-2, 14-4, 14-6, 14-8, 14-10, 14-12, 14-21)의 시일재 내부의 부분이 T형 및 사다리꼴형으로 되어 있고, 팽창부분(13-2, 13-4, 13-6, 13-8, 13-10, 13-12, 13-21)의 내부에 쐐기형으로 배치하고 있다. 이러한 구조로 하는 것에 의하여 팽창부분의 팽창방향이 더욱 규제되고, 또 팽창부분과 비팽창부분의 결합력이 강화된다.Each sealing material 12-2, 12-4, 12-6, 12-8, 12- of (a), (c), (e), (g), (i), (k) in said each Example 10, 12-12, 12-21 are portions inside the seal member of the non-expanded portions 14-2, 14-4, 14-6, 14-8, 14-10, 14-12, 14-21. It is T-shaped and trapezoidal, and is arranged in a wedge shape inside the inflation portions 13-2, 13-4, 13-6, 13-8, 13-10, 13-12, 13-21. . By such a structure, the expansion direction of the expanded portion is further regulated, and the bonding force between the expanded portion and the non-expanded portion is strengthened.
또 상기 각 실시예중(b), (c), (d), (e), (h), (i), (r), (s), (t)의 각 시일재(12-3, 12-4, 12-5, 12-6, 12-9, 12-10, 12-19, 12-20, 12-21)는 그 상면(첩부면과 반대측면)에 작은 돌기(15)가 설치된 것으로 이돌기(15)는 한개 내지 다수개 설치하면 좋다. 이러한 구조로 하는 것에 의하여 시일재을 이음새에 틈새없이 배치할 때 보울트와 너트에 의한 체결력이 적게되며 초기 방수성이 양호하게 된다.Moreover, each seal material 12-3, 12 of (b), (c), (d), (e), (h), (i), (r), (s), and (t) in each said embodiment. -4, 12-5, 12-6, 12-9, 12-10, 12-19, 12-20, and 12-21 are small projections (15) installed on the upper surface (opposite side of the patch). One to many protrusions 15 may be provided. By such a structure, when the seal member is disposed without any gap in the seam, the tightening force by the bolt and the nut is reduced and the initial waterproof is good.
또, 상기 각 실시예중(m), (n), (o), (p), (q)의 각 시일체(12-14, 12-15, 12-16, 12-17, 12-18)는 그 각 팽창부분내에 중공부(16)가 형성되어 조여 붙일때의 탄력성의 향상과 팽창재료의 절약을 도모할 수 있다. 상면을 사다리꼴 형상의 테이퍼면으로 한 시일재(12-7(f), 12-8(g), 12-9(h), 12-10(i), 12-16(o), 12-17(p),12-18(q), 상면의 양측부를 곡면으로한 12-21(t) 및 단면을 사다리꼴 형상으로한 12-20(s)도 동일한 목적을 달성하는 것이다.In addition, each seal body (12-14, 12-15, 12-16, 12-17, 12-18) of said (m), (n), (o), (p), (q) in said each Example The hollow portion 16 is formed in each of the inflated portions to improve the elasticity when tightening and to save the inflated material. Seal material with tapered surface of trapezoidal shape (12-7 (f), 12-8 (g), 12-9 (h), 12-10 (i), 12-16 (o), 12-17 (p), 12-18 (q), 12-21 (t) having both sides of the upper surface as a curved surface, and 12-20 (s) having a trapezoidal cross section, also achieve the same purpose.
그리고, 상기 각 실시예중(j), (k), (l), (q)의 각시일재(12-11, 12-12, 12-13, 12-18)는 그 각 비팽창부분(14-11, 14-12, 14-13, 14-18)이 다수개로 분할되어 접착면에 간격을 두고 설치되어 있다. 이러한 구조로하는 것에 의하여 사용장소의 상태에 따라서 접착강도와 접착면에서의 방수성 향상의 밸런스를 더욱 양호하게 할수 있다.In the above embodiments, the respective seal members 12-11, 12-12, 12-13, and 12-18 in (j), (k), (l), and (q) are each unexpanded portions 14-. 11, 14-12, 14-13, and 14-18) are divided into a plurality and are provided at intervals on the adhesive surface. With such a structure, it is possible to further improve the balance between the adhesion strength and the waterproof property improvement on the adhesive surface depending on the state of use place.
