본 고안은 옹벽 구조물 시공에서 소요되는 신축재의 정착력을 높혀 변형을 방지하고 서로 마주대하는 경계면의 양호한 수직도를 유지하기 위한 신축조인트에 관한 것이다.The present invention relates to the expansion joint to increase the anchoring force of the stretch material required in the construction of the retaining wall structure to prevent deformation and to maintain a good verticality of the interface facing each other.

지면을 구획하는 펜스, 도로변 낙석차단과 흘러내린 방지를 위해 축조된 도로변 칸막이벽, 견고한 지반에 축조하여 허약한 지반을 공고히 받쳐주는 축대 등과 같은 슬랩형 콘크리트 타설 구조물은 콘크리트 구조물의 신축 여유율을 제공할 목적으로 신축부재를 설치하고 있다.Slab-type concrete pouring structures, such as fences that partition the ground, roadside barrier blocks and roadside partition walls constructed to prevent spills, and shafts built on solid ground to firmly support fragile grounds, can provide a margin of expansion for concrete structures. Extension members are installed for the purpose.

상기 신축부재는 스치로폼과 같은 신축성이 있는 재질을 사용하여 콘크리트 구조물의 상호 신축작용에 의한 클랙 현상을 억제시키는데 구조물의 레이 아웃 단계에서 설치 위치를 고려한다.The elastic member uses an elastic material, such as styrofoam, to consider the installation position in the layout phase of the structure to suppress the crack phenomenon due to the mutual stretching of the concrete structure.

제1도는 콘크리트 구조물(1)에 신축부재(3)가 수직방향으로 자리잡은 모양을 나타낸 것으로 신축부재(3)는 콘크리트를 현장에서 부어넣는 단계에서 위치가 결정되어 제1도와 같이 바른 수직도와 고른 접합면을 얻는 쪽으로 시공이 행해지고 있다.FIG. 1 is a view showing a shape in which the elastic member 3 is positioned in the vertical direction in the concrete structure 1. The elastic member 3 is positioned at the stage of pouring concrete at the site, and the vertical member is evenly aligned with FIG. 1. Construction is performed toward the joint surface.

종래 옹벽 시공은 신축부재(3)의 설치단계를 기준으로 볼 때, 분리타설, 동시타설방법으로 구조물(1)을 형성한다.In the conventional retaining wall construction, the structure 1 is formed by a separate placing and a simultaneous placing method, based on the installation stage of the elastic member 3.

제2도는 콘크리트 분리 타설 방법을 예로서 보인 것으로 형판(2)에서 한쪽의 콘크리트(A)를 타설하고 경하되면, 일측면상에 신축부재(3)를 밀착시키고 형판(2)을 만들어 다시 또다른 콘크리트(B)를 타설화는 방법이고, 제3도는 동시타설 방법의 예를 보인 것으로 미리 형판(2)을 준비하고, 그 내부 사이공간 적소에 신축부재(3)를 적당 간격을 유지시킨 상태로 배치하여 각 형판(3)상에 마련된 공간에 콘크리트(A)(B)를 동시에 부어 경화시키는 방법이다.2 shows an example of the method of separating concrete, and when one concrete (A) is poured from the template (2) and lowered, the expansion member (3) is brought into close contact with one side and the template (2) is made again. (B) is a method of pouring, and FIG. 3 shows an example of a simultaneous placing method, in which a template 2 is prepared in advance, and the expansion and contraction member 3 is disposed at a proper interval in the interspace of the interior. The concrete (A) (B) is poured into the space provided on each template 3 at the same time and hardened | cured.

이 같은 분리타설, 동시타설 방법에 따른 신축부재(3)의 시공상태를 비교할 때 서로 장단점을 갖는다.When comparing the construction state of the elastic member (3) according to such a separate casting, simultaneous casting method has advantages and disadvantages.

분리타설 방법은 한쪽의 형판(2)에 콘크리트(A)를 타설하고 경화되면 상대측에 형판(2)을 만들어 다시 콘크리트(B)를 타설하는 과정을 거침으로서 한쪽의 콘크리트(A)가 경화될 때까지 이후 타설작업이 연속적으로 이루어지지 못해 작업이 지연되는 반면 신축부재(3) 시공시 타설이 완료되어 경화가 끝난 타설 콘크리트(A)에 의탁시킨채로 이후 콘크리트(B)를 타설하게 됨으로서 신축부재(3)의 뒤틀림이나 변형현상을 줄여 주어 비교적 신축부재(3)의 바른 타설 상태를 얻을 수 있다.In the separate casting method, when one concrete (A) is hardened by placing concrete (A) on one side of the template (2) and then curing, the mold (2) is made on the other side and the concrete (B) is poured again. Since the work is delayed because it is not possible to continuously perform the casting work afterwards, while the expansion of the new building member (3) is completed, the concrete (B) is poured into the finished concrete (A) while being placed on the hardened concrete. By reducing the warpage and deformation of 3), it is possible to obtain a correct casting state of the elastic member (3).

동시타설 방법은 형판(2)을 미리 길이 방향으로 길게 형성한 상태에서 신축부재(3)를 적소에 배치하고 동시에 전후 구분없이 콘크리트(A)(B)를 형판(2)에 부어 넣는 방법으로서 빠른 시간내에 형판(2)을 채워 작업시간을 대폭 줄일 수 있는 반면 형판(2)내에 세워진 신축부재(3)가 콘크리트(A)(B)의 채워짐 양에 따라 신축부재(3)에 의해 구분되는 이웃 콘크리트(A)(B)측과의 상호 밀림 작용에 따라 뒤틀리거나 변형되어 콘크리트가 경화되면 신축부재(3)의 수직도가 유지되지 않음은 물론 고른 타설면을 얻을 수 없는 단점이 있다.The simultaneous casting method is a method of placing the stretchable member 3 in place in a state where the template 2 is formed in the longitudinal direction in advance, and at the same time, pouring concrete (A) (B) into the template 2 without distinction between front and rear. The working time can be drastically reduced by filling the template 2 in time, while the expansion and contraction member 3 built in the template 2 is divided by the expansion and contraction member 3 according to the filling amount of concrete (A) and (B). If the concrete is twisted or deformed due to mutual sliding action with the concrete (A) and (B) sides, the verticality of the stretchable member 3 is not maintained, and there is a disadvantage in that an even pouring surface cannot be obtained.

또한 이같은 신축부재 시공에 의한 타설방법에서는 신축부재(3)의 고른 타설상태 유지와 외관을 미려한 상태로 유지하기 위해 보통 전면부측에 면목(4)을 부설하여 구배를 두고 있다. 따라서 면목(4) 부설에 따른 작업공정과 콘크리트 타설 완료후 형판(2) 제거와 면목 제거작업을 추가로 실시하는 시공작업을 동반한다. 한편 옹벽구조물(1) 시공에서 기본적으로 응용되는 분리, 동시타설방법에서 신축부재(3)의 시공은 수회의 작업공정을 필요로 하거나 콘크리트 타설과정에서 신축부재(3)의 변형이 발생되어 옹벽의 미려한 외관을 얻을 수 없고, 또한 콘크리트의 수축/신장 변형을 무마시키기 위한 세심한 주위가 요구되었으며, 그런 가운데 작업성이 떨어지는 문제점이 있었다.In addition, in the placing method by the construction of the elastic member construction, in order to maintain the evenly placed state and the appearance of the elastic member 3 in a beautiful state, a surface wood 4 is usually placed on the front side to give a gradient. Therefore, it is accompanied by the construction process of additionally removing the template (2) and removing the face wood after the work process according to laying the face wood (4) and the completion of concrete pouring. On the other hand, in the separation and simultaneous placing method that is basically applied in retaining wall structure (1) construction, the construction of the expansion and contraction member (3) requires several working steps or the deformation of the expansion and contraction member (3) occurs during the concrete placement process. A beautiful appearance could not be obtained, and a careful surrounding was required to smooth the shrinkage / extension deformation of the concrete, and in the meantime, workability was inferior.

따라서 본 고안은 이와같은 종래 문제점을 해소시키기 위하여 신축부재의 변위에 대해서 수직방향으로 신축성을 갖는 신축조인트를 제공하는 것에 의해 신축부재의 고른 수직도를 유지하는 가운데 신축성과 신축부재의 시공외관을 동시에 만족시킬 수 있도록 한 것이다.Therefore, the present invention provides an elastic joint having elasticity in the vertical direction with respect to the displacement of the elastic member in order to solve such a conventional problem, while maintaining the even verticality of the elastic member while maintaining the construction appearance of the elastic member. It is to satisfy.

본 고안의 구성은 제4도 및 제5도와 같이 콘크리트 구조물 형판(2)내에 세워지고 바깥면은 패널(9)로 쌓여진 신축부재(3a)를 안내하여 형판(2)내에 결합시키기 위한 신축부재 안내공간(6)을 가지며, 상기 안내공간(6)을 중심으로 좌우 양편에 대칭적으로 신축부재(3a)의 좌우 유동을 자유롭게 하는 신축공간(7)을 구비하는 신축조인트에 있어서, 상기 신축공간(7)을 안쪽에 두고, 그 바깥쪽으로는 형판(2)에 대하여 면접촉 가능한 나란한 대칭면을 가지는 형판접촉면(10)을 형성하고, 상기 형판접촉부(10)를 형판(2)에 면접촉시키되, 형판 고정플랜지(11)부를 고정핀(8)으로 고정하여 신축부재(3a)를 지지하는 콘크리트 옹벽 구조물의 신축조인트로 구성된다.The construction of the present invention guides the expansion and contraction member for coupling in the template 2 by guiding the expansion and contraction members 3a stacked in the concrete structure template 2 and the outer surface of the panel 9 as shown in FIGS. 4 and 5. In the expansion joint having a space (6) and having an expansion space (7) for lateral flow of the expansion and contraction member (3a) symmetrically on both left and right sides of the guide space (6), the expansion space ( 7) with the inner side, the outer side forms a plate contact surface 10 having a parallel symmetrical surface that can be in surface contact with the template (2), and the plate contact portion 10 is in surface contact with the template (2), The fixing flange 11 is fixed to the fixing pin 8 to be composed of the expansion joint of the concrete retaining wall structure for supporting the stretching member (3a).

즉, 제5도와 같이 형판(2)을 조합하여 콘크리트 구조물(1)을 형성하도록 하는 각 형판(2) 사이사이에 신축부재(3a)를 설치하되 형판(2) 내에서 신축부재(3a)를 신축적으로 지지하는 신축조인트(5)에 의해 신축부재(3a)를 형판(2)내에 고정한다. 상기 신축조인트는 형판(2) 내에 수직으로 세워지는 신축부재(3a)를 안내하여 결합시키기 위한 안내공간(6)과 이 안내공간(6)을 중심으로 좌우 양편에 대칭적으로 신축부재(3a)의 좌우 유동을 자유롭게 하는 신축공간(7)을 가지며, 동시에 형판접촉면(10)을 갖는다.That is, as shown in FIG. 5, the expansion and contraction members 3a are installed between the respective templates 2 to form the concrete structure 1 by combining the templates 2, and the expansion and contraction members 3a are disposed within the template 2. The elastic member 3a is fixed in the template 2 by the elastic joint 5 which is elastically supported. The expansion joint is a guide space (6) for guiding and coupling the expansion and contraction member (3a) standing vertically in the template (2) and the expansion and contraction member (3a) symmetrically on both left and right sides around the guide space (6) It has an expansion space (7) for freeing the left and right flow of, and at the same time has a template contact surface (10).

따라서 신축조인트(5)에 의한 신축부재(3a)의 고정은 임의의 형판(2) 내벽면에 신축조인트(5)의 형판접촉면(10)을 형판(2)의 안쪽면에 밀착시킨 상태에서 고정핀(8)으로 고정하고, 이와 상대되는 신축조인트(5)를 전자와 같은 방법으로 고정하여 신축부재(3a)를 안내공간(6)에 끼워넣거나 또는 신축부재(3a)의 양측면을 먼저 신축조인트 안내공간(6)에 끼워 결합시킨 상태에서 신축조인트(5)를 형판(2)의 내벽면에 고정한다.Accordingly, the expansion and contraction of the expansion and contraction member 3a by the expansion joint 5 is fixed in a state in which the template contact surface 10 of the expansion joint 5 is in close contact with the inner surface of the template 2 on the inner wall surface of the arbitrary template 2. The pin 8 is fixed, and the elastic joint 5 corresponding thereto is fixed in the same manner as the former to insert the elastic member 3a into the guide space 6, or both sides of the elastic member 3a are stretched first. The expansion joint 5 is fixed to the inner wall surface of the template 2 in a state of being fitted into the guide space 6.

상기와 같은 신축조인트(5)의 시공을 완료한 상태에서 형판(2)내에 콘크리트를 쏟아 부으면, 콘크리트 경계면에 신축조인트(5)에 의해 지지되는 신축부재(3a)에 의한 1차신축과 신축부재(3a)를 지지하는 신축조인트(5)의 2차 신축작용을 통해 콘크리트측으로부터 전달되는 변형에 대한 신축 여유율을 제공하게 된다.When the concrete is poured into the template 2 while the construction of the expansion joint 5 is completed as described above, the primary expansion and contraction member by the expansion and contraction member 3a supported by the expansion joint 5 on the concrete interface. Secondary expansion of the expansion joint (5) supporting (3a) is to provide the expansion margin for the deformation transmitted from the concrete side.

한편, 신축조인트(5)를 사용하여 신축부재(3a)를 지지하고 또한 신축조인트(5)를 형판(2)에 고정시킬 경우 신축조인트(5)의 바깥면인 형판접촉면(10)을 형판(2)에 밀착시키고, 고정플랜지(11)를 통해 안쪽 방향에서 고정핀(8)으로 형판(2)에 신축조인트(5)를 고정한 뒤 콘크리트를 타설함으로써 신축조인트(5) 및 신축부재(3a)의 유동이나 쏠림이 예방되고, 콘크리트 타설 완료후 형판(2)을 제거하면 신축조인트(5)의 형판접촉면(10)이 콘크리트 구조물(1)과 나란한 동일면을 형성함으로써 고른 수직도를 유지하여 별도의 면목의 설치가 필요없고 균일한 설치와 외관이 나타난다.On the other hand, when the expansion joint 5 is used to support the expansion member 3a and the expansion joint 5 is fixed to the template 2, the plate contact surface 10, which is the outer surface of the expansion joint 5, is formed from the template ( 2), the expansion joint (5) and the expansion member (3a) by fixing the expansion joint (5) to the template (2) with the fixing pin (8) in the inward direction through the fixing flange 11 and then pouring concrete Flow or deflection is prevented, and when the template (2) is removed after completion of concrete pouring, the template contact surface (10) of the expansion joint (5) forms the same plane parallel to the concrete structure (1) to maintain an even vertical angle There is no need to install the face, uniform installation and appearance.

이와같이 본 고안은 콘크리트 타설전 단계에서 형판에 접촉되어 고정되는 신축조인트를 적용함으로써 별도의 면목 설치 없이 고른 외관을 얻을 수 있을 뿐만 아니라 작업 단계에서 콘크리트 밀림에 의한 신축조인트 및 신축부재의 이탈 현상이 없어 작업성을 향상시키는 효과가 있다.In this way, the present invention can obtain a uniform appearance without installing a separate facet by applying the expansion joint fixed in contact with the template in the pre-concretion stage, and there is no detachment phenomenon of the expansion joint and expansion member due to the concrete jungle in the working stage. It is effective to improve workability.
