Preferably, as shown, the filler 40 is inserted so that the end of the stretchable member 10 protrudes from the filler 40, and the end of the formwork 2 for pouring concrete is the filler 40 and Formwork is installed to contact the inner surface of the end forming the opening 11 of the elastic member 10. In this way, since the installation position of the formwork 2 is regulated at the end of the stretching member 10, the installation position of the formwork is set incorrectly, and the problem that concrete enters the expansion member 10 is solved. Reference numeral 38 is a bolt for coupling the elastic member 10 and the filler 40.

이와 같이 하여 신축이음장치 일측에 콘크리트를 타설하여 구조물의 일부룰 단위길이로 구축한 후, 구조물 단부에 신축이음장치의 폭에 해당되는 두께를 가지는 스티로폼 등을 배치하고 신축이음장치의 타측에 구조물의 일부를 구축한다. In this way, the concrete is placed on one side of the expansion joint device to build the unit length of a part of the structure, and then the styrofoam having a thickness corresponding to the width of the expansion joint device is placed at the end of the expansion joint. Build some.

도 4와 도 5는 본 발명의 다른 실시예를 보인 것으로서, 신축부재(10)의 개구부(11)에 커버(42)가 씌워진 것이다. 이와 같이 신축부재(10)에 커버를 씌우면, 전술한 바와 같이 신축부재(10)의 개구부(11)에 볼트(38)를 체결시키는 것 보다 조립이 간편한 장점이 있다. 또한, 이 커버(42)에 의해 콘크리트 타설시 콘크리트물이 상기 충진재(40)로 유입되어 충진재(40)가 콘크리트에 의해 굳는 것이 방지된다. 4 and 5 show another embodiment of the present invention, in which the cover 42 is covered by the opening 11 of the elastic member 10. Covering the expansion and contraction member 10 in this way, there is an advantage that the assembly is easier than fastening the bolt 38 to the opening 11 of the expansion and contraction member 10 as described above. In addition, when the concrete is poured by the cover 42, concrete is introduced into the filler 40 to prevent the filler 40 from being hardened by the concrete.

또한, 바람직하게는 도시된 바와 같이, 커버(42)에는 거푸집(2)의 단부가 걸리는 걸림턱(43)이 형성된다. 따라서 도 4에 도시된 바와 같이, 거푸집(2)을 상기 걸림턱(43)에 맞추어 설치하면, 거푸집(2)을 정위치에 용이하게 설치할 수 있는 장점이 있다. In addition, as shown, the cover 42 is formed with a latching jaw 43 to which the end of the formwork 2 is caught. Therefore, as shown in Figure 4, if the formwork (2) is installed in accordance with the locking step 43, there is an advantage that the formwork (2) can be easily installed in place.
