이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 4 이하에 도시된 바와 같이, 본 발명에 의한 티형 PC 슬래브는 기본적으로, 패널부(100); 패널부(100)의 양단에 형성된 댑 단부(150); 패널부(100)의 저면에 하측으로 연장 형성됨과 아울러, 댑 단부(150)와 연결된 복부(200); 패널부(100)의 양측에 형성된 전단키(170);를 포함하고, 전단키(170)는 패널부(100)의 측단에 형성된 연결철근 삽입홈(173)을 포함하여 구성된다.As shown in Figure 4 below, the tee-type PC slab according to the present invention basically comprises a panel portion 100; A adapter end 150 formed at both ends of the panel unit 100; An abdomen 200 extending downward from the bottom surface of the panel unit 100 and connected to the end portion 150 of the panel 100; Shear keys 170 formed on both sides of the panel unit 100; The shear key 170 is configured to include a connecting reinforcing bar insertion groove 173 formed on the side end of the panel unit 100.

즉, 패널부(100)의 양측에 인접하여 설치되는 슬래브와 연결을 위한 전단키(170)를 설치하되, 그 전단키(170)는 후술하는 연결철근(400)이 삽입되는 연결철 근 삽입홈(173)의 구조를 취하도록 한 것을 특징으로 한다.That is, the shear key 170 for the connection with the slab is installed adjacent to both sides of the panel portion 100 is installed, the shear key 170 is a connecting reinforcement groove 173 is inserted into the connecting reinforcement 400 to be described later It is characterized by taking the structure of).

이와 같이 본 발명에 의한 슬래브는 패널부(100)의 양측에 전단키(170)가 형성되어, 인접 슬래브의 패널부(100a)와 결합할 수 있으므로, 인접하여 설치되는 양 슬래브의 패널부의 높이를 일정하게 조절할 수 있어, 종래와 같은 응력집중에 의한 측면균열을 방지할 수 있다.As described above, in the slab according to the present invention, shear keys 170 are formed at both sides of the panel portion 100, so that the slabs can be combined with the panel portion 100a of the adjacent slab, so that the heights of the panel portions of both slabs which are adjacently installed are fixed. It can be adjusted so as to prevent side cracks caused by stress concentration as in the prior art.

이러한 구조를 취하는 슬래브는 다음과 같은 공정에 의해 시공된다.Slabs having this structure are constructed by the following process.

슬래브를 지지하는 보(300)를 설치하고, 티형 PC 슬래브 및 이에 인접하여 설치될 티형 PC 슬래브를 댑 단부(150)를 이용하여 보(300) 상에 연속되게 설치한다(도 5).A beam 300 supporting the slab is installed, and the tee-type PC slab and the tee-type PC slab to be installed adjacent thereto are continuously installed on the beam 300 by using the adapter end 150 (FIG. 5).

티형 PC 슬래브의 연결철근 삽입홈(173) 및 인접 티형 PC 슬래브의 연결철근 삽입홈(173a)에 의해 형성된 연결철근 삽입부(410)에 사선 방향으로 연결철근(400)을 설치하되, 연결철근(400)의 양단이 각각 상기 티형 PC 슬래브의 연결철근 삽입홈(173) 및 인접 티형 PC 슬래브의 연결철근 삽입홈(173a)의 내면에 접촉하도록 한다(도 7).The connecting reinforcing bars 400 are installed in the connecting reinforcing bar insertion slots 410 formed by the connecting bar insertion grooves 173 of the tee-type PC slab and the connecting bar insertion grooves 173a of the adjacent tee-type PC slab, but the connecting bars ( Both ends of 400 are respectively in contact with the inner surfaces of the connecting bar insertion groove 173 of the tee-type PC slab and the connecting bar insertion groove 173a of the adjacent tee-type PC slab (FIG. 7).

이와 같이 연결철근(400)을 사선 방향으로 설치하는 경우, 망치 등에 의해 연결철근(400)을 타격함으로써, 인접하여 설치되는 양측의 티형 PC 슬래브와의 높이를 맞출 수 있다.In this way, when the connecting reinforcing bar 400 is installed in an oblique direction, by hitting the connecting bar 400 with a hammer or the like, it is possible to match the height with the tee-type PC slabs on both sides to be adjacently installed.

높이를 맞춘 이후, 연결철근 삽입부(410)를 포함하여 콘크리트가 타설되도록, 토핑 콘크리트(1)를 타설한다.After adjusting the height, the topping concrete 1 is poured so that the concrete is poured, including the connecting reinforcing rod inserting portion 410.

여기서, 연결철근(400)의 양단이 연결철근 삽입홈(173) 및 인접 티형 PC 슬 래브의 연결철근 삽입홈(173a)의 내면에 접촉하여 안정적인 정착구조를 이루기 위해서는, 연결철근(400)은 I형 단면의 구조를 취하는 것이 바람직하다(도 7).Here, both ends of the connecting reinforcing bar 400 is in contact with the inner surface of the connecting reinforcing groove 173 and the connecting reinforcing bar insertion groove 173a of the adjacent tee-type PC slab to achieve a stable fixing structure, the connecting reinforcement 400 is I It is preferable to take the structure of a mold cross section (FIG. 7).

나아가, 연결철근(400)이 상호 간격을 두고 복수가 설치되되, 그 복수의 연결철근(400a,400b)이 상호 반대방향을 향하는 사선 방향으로 설치되는 경우, 복수의 연결철근(400a,400b) 중 하나를 타격하면 한 쪽의 슬래브가 올라가고, 다른 하나를 타격하면 다른 쪽의 슬래브가 올라가는 방식으로 높이를 조절할 수 있으므로, 시공의 편의성 측면에서 더욱 바람직하다(도 8).Furthermore, when the plurality of connecting reinforcing bars 400 are installed at intervals with each other, and the plurality of connecting reinforcing bars 400a and 400b are installed in an oblique direction facing each other, the plurality of connecting reinforcing bars 400a and 400b. When one hits the slab of one rises, the other hitting the other side of the slab rises in a way that can be adjusted, it is more preferable in terms of construction convenience (Fig. 8).

이러한 구조의 전단키(170)(연결철근 삽입홈(173))는 패널부(100)의 양측면에 직접 형성될 수도 있으나, 이로 인하여 패널부(100)의 두께가 두꺼워지는 것을 방지하기 위해서는 다음과 같은 구조를 취하는 것이 바람직하다.The shear key 170 (connecting reinforcement groove 173) of this structure may be formed directly on both sides of the panel portion 100, but because of this to prevent the thickness of the panel portion 100 is thick as follows: It is desirable to take the structure.

즉, 슬래브는 패널부(100)의 측단의 내측 저면에서 하측으로 연장형성된 연장부(171); 연장부(171)의 하단에서 외측으로 연장형성된 하측돌부(172);를 포함하고, 연결철근 삽입홈(173)은 패널부(100)의 측단, 연장부(171) 및 하측돌부(172)의 내측영역에 의해 형성되는 구조가 그것이다(도 6).That is, the slab is an extension portion 171 extending downward from the inner bottom surface of the side end of the panel portion 100; And a lower protrusion 172 extending outward from a lower end of the extension part 171, wherein the connection reinforcing bar insertion groove 173 includes the side ends of the panel part 100, the extension part 171, and the lower protrusion 172. That is the structure formed by the inner region (Fig. 6).

하측돌부(172)가 패널부(100)의 측단에 비해 외측으로 더 돌출된 구조를 취하는 경우, 인접 슬래브와의 결합 시 하측돌부(172)는 상호 접촉하고, 패널부(100)의 측단 사이는 벌어지는 구조가 되므로, 자연스럽게 연결철근(400)의 설치 및 위 높이 보정작업을 위한 공간을 확보할 수 있다는 장점이 추가된다.When the lower side protrusion 172 has a structure that protrudes outward more than the side end of the panel portion 100, the lower side protrusion 172 is in contact with each other when the adjacent slab is engaged, and between the side ends of the panel portion 100 Since it becomes a structure that opens, it is added to the advantage that it is possible to secure a space for the installation of the connecting reinforcement 400 and the height correction work naturally.

댑 단부(150)는 티형 PC 슬래브 단부의 과도 전단력을 지지하도록 상기 패널부(100)의 두께보다 두껍게 형성되는 것이 바람직하다.The adapter end 150 is preferably formed thicker than the thickness of the panel portion 100 to support the excessive shear force of the tee PC slab end.

슬래브의 복부(200)는 하나만 형성될 수도 있으나, 복수가 형성되는 것이 구조적 안정성 및 운반, 보관의 편의성 측면에서 더욱 바람직하다.The abdomen 200 of the slab may be formed only one, it is more preferable in terms of structural stability and convenience of transportation, storage is formed.

복부(200)가 패널부(100)의 단부로부터 간격을 두고 내측에 설치되는 경우, 패널부(100)의 단부 하부 영역에 덕트(350) 설치부가 형성되므로, 덕트(360)의 설치로 인하여 층고가 높아지는 상황을 방지할 수 있다는 효과가 추가된다(도 9).When the abdomen 200 is installed on the inner side at a distance from the end of the panel portion 100, since the duct 350 is installed in the lower region of the end portion of the panel portion 100, the height of the duct 360 may be due to the installation of the duct 360. The effect of preventing the situation from becoming high is added (FIG. 9).

이상은 본 발명에 의해 구현될 수 있는 바람직한 실시예의 일부에 관하여 설명한 것에 불과하므로, 주지된 바와 같이 본 발명의 범위는 위의 실시예에 한정되어 해석되어서는 안 될 것이며, 위에서 설명된 본 발명의 기술적 사상과 그 근본을 함께 하는 기술적 사상은 모두 본 발명의 범위에 포함된다고 할 것이다.Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
