Description

경량성형재조립체에 의한 중공슬래브의 시공구조{Hollow core slab by light weight assembly}Hollow core slab by light weight assembly}

본 발명은, 용접철망에 다수개의 경량성형재를 결속시켜 완성한 경량성형재조립체를 이용하여 중공슬래브(Hollow Core Slab)를 시공함에 있어, 경량성형재조립체의 부상(浮上)을 억제하는 것은 물론 경량성형재조립체를 그 위의 슬래브상부철근과 소정 거리 이격 배치된 상태로 슬래브콘크리트에 매입시킬 수 있는 중공슬래브의 시공구조에 관한 것이다.The present invention, in the construction of a hollow slab (hollow core slab) using a lightweight molded material assembly by binding a plurality of lightweight molded material to the welded wire mesh, it is possible to suppress the rise of the lightweight molded material assembly as well as light weight It relates to a construction structure of a hollow slab that can be embedded in the slab concrete in a state in which the molding material assembly is disposed at a predetermined distance apart from the upper slab on the slab.

중공슬래브(hollow core slab)는 도 1과 같이 중앙에 중공(hollow core)을 구비한 구조로서 패널 중량을 감소시킴에 따라 자중에 비해 비교적 우수한 단면 성능을 가지며, 이러한 중공슬래브는 장경간(long span)과 무량판(flat slab)의 구현은 물론 층간소음 저감에 유리한 장점을 가진다.Hollow core slab (hollow core slab) is a structure having a hollow core in the center as shown in Figure 1 and has a relatively excellent cross-sectional performance compared to its own weight as the panel weight is reduced, the hollow slab has a long span ) And flat slabs, as well as the advantage of reducing the noise between floors.

통상 중공슬래브는 중공 형성 등 현장작업이 어려워 공장에서 제작된 PC제품으로 채택하는 것이 일반적이다. 하지만, 공장제작의 중공슬래브는 별도의 기계설 비가 요구될 뿐 아니라 중공 형성을 위한 제작과정이 상당히 복잡하다는 점이 단점으로 지적된다. 아울러, 그 자체가 완전한 슬래브 구조체가 되기 때문에 일정 이상의 중량감을 가지는 것이 당연하므로 이의 운반 및 양중에 불편함이 있으며, 나아가 기둥 또는 보와의 일체 접합을 위해 중공형 슬래브의 단부 구성이 복잡해지는 문제가 있다.In general, the hollow slab is difficult to work in the field, such as forming a hollow, it is generally adopted as a PC product manufactured in the factory. However, it is pointed out that the hollow slab of the factory manufacturing is not only required for the separate machine installation, but also the manufacturing process for forming the hollow is quite complicated. In addition, since it is natural to have a certain weight or more because it is a complete slab structure itself, there is inconvenience in carrying and lifting thereof, and furthermore, there is a problem that the end configuration of the hollow slab becomes complicated for integral bonding with a column or beam. have.

이러한 문제를 해결하기 위해 중공을 스티로폼 등의 경량성형재로 형성하는 방법이 제안되고 있다. 즉, 중공이 형성될 위치에 경량성형재를 배치하여 현장에서 타설되는 콘크리트에 매입되도록 한 것이다. 하지만, 이와 같은 중공슬래브의 경우에는 다수개의 경량성형재를 일일이 배치하여 고정 설치해야 하므로 그 작업은 상당히 번거롭다는 불편을 수반한다.In order to solve this problem, a method of forming a hollow molding material such as styrofoam has been proposed. In other words, by placing the lightweight molding material in the position where the hollow will be formed to be embedded in the concrete to be poured in the field. However, in the case of such a hollow slab, a number of lightweight molding members have to be arranged and fixed to be installed one by one, so the work is inconvenient.

상기와 같은 문제해결을 위해 중공슬래브 시공에 유용하게 적용할 수 있도록 다수개의 경량성형재(120)를 용접철망(110)에 결속하여 하나의 조립체 형태로 완성한 경량성형재조립체(100)가 개발된 바 있으며, 도 2a 내지 도 2c는 그러한 경량성형재조립체(100)와 다양한 조립방법 및 다양한 형상의 경량성형재를 보여준다.In order to solve the problems as described above, the lightweight molding material assembly 100 is completed by binding a plurality of lightweight molding members 120 to the welded wire mesh 110 so as to be usefully applied to the construction of a hollow slab. 2a to 2c show such a lightweight molded article assembly 100 and various assembly methods and lightweight shaped members of various shapes.

하지만, 도 2a와 같은 경량성형재조립체를 거푸집 위에 그대로 설치하고 콘크리트를 타설한다면, 경량성형재조립체는 콘크리트 타설압과 콘크리트 하중에 의해 부력이 작용하면서 쉽게 부상하므로 안정적인 위치로 콘크리트에 매입시키기 어렵다. 따라서, 경량성형재조립체를 이용하여 중공슬래브를 시공하는 경우에는 안정적인 중공위치를 확보하기 위한 대책을 별도 마련할 필요가 있다.However, if the lightweight molding assembly as shown in Figure 2a is installed on the form as it is and cast concrete, the lightweight molding assembly is difficult to buried in concrete in a stable position because buoyancy acts easily due to the concrete placing pressure and concrete load. Therefore, when constructing a hollow slab using a lightweight molding material assembly, it is necessary to separately prepare measures to secure a stable hollow position.

본 발명은 상기한 종래의 문제를 해결하고자 개발된 것으로서, 경량성형재조립체의 부상(浮上)을 억제하면서 경량성형재조립체를 그 위의 슬래브상부철근과 소정 거리 이격 배치된 상태로 슬래브콘크리트에 매입시킬 수 있는 중공슬래브의 시공구조를 제공하는데 기술적 과제가 있다.The present invention was developed in order to solve the above-described problems, and the lightweight molding assembly is embedded in the slab concrete in a state in which the lightweight molding assembly is disposed at a predetermined distance from the slab upper reinforcement thereon while suppressing the rise of the lightweight molding assembly. There is a technical problem in providing a construction structure of hollow slab that can be made.

상기한 기술적 과제를 해결하기 위해 본 발명은, 철선을 교차 접합한 용접철망에 다수개의 경량성형재를 띄엄띄엄 결속시켜 제작한 경량성형재조립체를 이용하면서 상기 경량성형재조립체 위로 이격하게 슬래브상부철근이 배근되도록 중공슬래브를 시공함에 있어, 상기 경량성형재조립체에 상향돌기편이 상방으로 돌출되게 마련하여 슬래브상부철근이 상향돌기편에 걸리게 배근하거나, 상기 슬래브상부철근에 하향돌기편이 하방으로 돌출되게 마련하여 경량성형재조립체가 하향돌기편에 걸리게 설치하는 것을 특징으로 하는 중공슬래브의 시공구조를 제공한다.In order to solve the above technical problem, the present invention, while using a lightweight molding assembly fabricated by randomly binding a plurality of lightweight molding material to the welded wire mesh cross-bonded steel wire, the upper slab reinforcement spaced apart above the lightweight molding material assembly In constructing the hollow slab so that the reinforcement is provided, the upwardly protruding piece is protruded upward in the lightweight molding material assembly so that the upper slab is placed on the upwardly protruding piece or the downwardly protruding piece is protruded downward in the upper slab. It provides a construction structure of the hollow slab characterized in that the lightweight molding assembly is installed on the downward projection piece.

본 발명에 따르면, 용접철망에 다수개의 경량성형재를 결속시켜 완성한 경량성형재조립체를 이용하여 중공슬래브를 시공할 때 경량성형재조립체를 슬래브상부 철근과 소정 거리 이격 배치된 상태로 일정한 위치에 안정적으로 고정시킬 수 있다. 이에 따라 중공위치를 일정하게 확보하는 중공슬래브를 용이하게 시공할 수 있으며, 아울러 슬래브상부철근을 슬래브콘크리트에 충분히 구속시킬 수 있기 때문에 구조적으로 유리하게 중공슬래브를 완성할 수 있다.According to the present invention, when constructing a hollow slab using a lightweight molding assembly completed by binding a plurality of lightweight molding members to a welded wire mesh, the lightweight molding assembly is stable at a predetermined position while being spaced apart from the upper slab by a predetermined distance. Can be fixed with Accordingly, it is possible to easily construct a hollow slab that ensures a constant hollow position, and also it is possible to structurally advantageously complete the hollow slab because the upper slab reinforcement can be sufficiently constrained to the slab concrete.

이하, 첨부한 도면 및 바람직한 실시예에 따라 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

도 3a 내지 도 5c는 본 발명에 따른 중공슬래브의 시공구조에 대한 다양한 실시예를 보여준다. 본 발명은 중공슬래브를 시공함에 있어, 철선을 교차 접합한 용접철망(110)에 다수개의 경량성형재(120)를 띄엄띄엄 결속시켜 제작한 경량성형재조립체(100)를 이용하고, 상기한 경량성형재조립체(100) 위로 일정 거리 이격하게 슬래브상부철근(200)을 배근하기 위해 경량성형재(120)와 슬래브상부철근(200) 사이에 간격재를 위치시킨다는데 기술적 특징이 있다. 본 발명은 간격재의 형태에 따라 3가지의 구체적인 실시예를 제안한다.Figures 3a to 5c shows various embodiments of the construction structure of the hollow slab according to the present invention. In the present invention, in the construction of a hollow slab, using the lightweight molding assembly 100 produced by randomly binding a plurality of lightweight molding member 120 to the welded wire mesh 110, the cross-bonded steel wire, There is a technical feature of placing the spacer between the lightweight molding member 120 and the slab upper reinforcement 200 in order to reinforce the slab upper reinforcement 200 at a predetermined distance above the molding material assembly 100. The present invention proposes three specific embodiments according to the shape of the spacer.

도 3a 내지 도 3d는 본 발명에 따른 중공슬래브의 시공구조에 대한 제1실시예로, 경량성형재(120)와 슬래브상부철근(200) 사이에 위치하는 간격재를 경량성형재(120)에 일체형의 상향돌기편(130)으로 마련한 예이다.3a to 3d is a first embodiment of the construction structure of the hollow slab according to the present invention, the spacer positioned between the lightweight molding member 120 and the upper slab upper reinforcement 200 to the lightweight molding member 120 It is an example provided with an integrated upward protrusion piece 130.

제1실시예에서 상향돌기편(130)은 경량성형재조립체(100)에서 다수개의 경량 성형재(120) 중 하나 이상의 경량성형재(120)의 상부에 돌출되게 마련된다. 도 3b에서는 십자형의 상향돌기편(130)이 경량성형재(120)에 일체로 형성된 형태를 확인할 수 있으며, 이러한 상향돌기편(130)은 경량성형재(120) 제작과정에서 경량성형재(120)와 함께 성형된다. 상향돌기편(130)은 도 3c에서와 같이 경량성형재조립체(100)에서 일부의 경량성형재(120)에만 마련하는 것이 바람직한데, 이는 상향돌기편(130)에 의한 슬래브상부철근(200)의 콘크리트 부착면적 손실을 최소화하여 슬래브상부철근(200)의 슬래브콘크리트(A3)에의 구속력을 증대시키기 위함이다. In the first embodiment, the upwardly protruding piece 130 is provided to protrude above the one or more lightweight molding members 120 of the plurality of lightweight molding members 120 in the lightweight molding member assembly 100. In FIG. 3B, the cross-shaped upwardly protruding piece 130 may be formed integrally with the lightweight molding member 120, and the upwardly protruding piece 130 may be formed of the lightweight molding member 120 in the process of manufacturing the lightweight molding member 120. Is molded together. The upwardly protruding piece 130 is preferably provided only to a part of the lightweight molding material 120 in the lightweight molding material assembly 100 as shown in FIG. 3C, which is the upper slab reinforcement 200 by the upwardly protruding piece 130. This is to increase the restraint force on the slab concrete (A3) of the slab upper reinforcement (200) by minimizing the loss of concrete attachment area.

경량성형재조립체(100)에 상향돌기편(130)이 마련됨에 따라, 중공슬래브의 시공구조에서 슬래브상부철근(200)은 도 3a에서와 같이 상향돌기편(130)의 수직 상방 위치에서 상향돌기편(130)과 교차하도록 배근되어야 하며 아울러 슬래브상부철근(200)의 배근 상태가 고정되어야 한다. 그래야 슬래브콘크리트(A3) 타설과정에서 경량성형재조립체(100)가 부력에 의해 부상할 때 상향돌기편(130)이 슬래브상부철근(200)에 걸리면서 그 부상이 억제되며, 이로써 상향돌기편(130)에 의해 경량성형재(120)와 슬래브상부철근(200)의 간격이 유지된다. 슬래브상부철근(200)의 배근 상태를 고정하는 것은 경량성형재조립체(100)의 부력에 의해 들려지는 것을 차단하기 위함이다. 도 3a에서는 결속선(B5)을 묶어 슬래브상부철근(200)의 배근 상태를 고정하고 있다.As the upwardly projecting piece 130 is provided in the lightweight molding material assembly 100, the upper slab reinforcement 200 in the construction structure of the hollow slab is upwardly projected in the vertically upward position of the upwardly projecting piece 130 as shown in FIG. 3A. The reinforcement to intersect with the piece 130 and the reinforcement state of the upper slab reinforcement 200 should be fixed. That is, when the lightweight molding material assembly 100 rises due to buoyancy in the slab concrete (A3) casting process, the upward protrusion 130 is caught by the upper slab reinforcement 200 and the injury is suppressed, thereby increasing the upward protrusion (130). By maintaining the distance between the lightweight molding member 120 and the slab upper reinforcement (200). Fixing the reinforcement state of the upper slab reinforcement 200 is to block the lift by the buoyancy of the lightweight molding material assembly 100. In FIG. 3A, the binding line B5 is tied to fix the reinforcement state of the upper slab reinforcement 200.

도 3d는 도 3a에 따른 중공슬래브의 시공구조가 적용되는 과정을 보여준다. 먼저 하부철근받침대(B1)를 고정못(B2)으로 슬래브거푸집(A1)에 고정 설치하고, 슬래브하부철근(A2)을 하부철근받침대(B1)에 안착시키면서 배근한다. 슬래브거푸 집(A1)으로 데크플레이트와 같은 존치거푸집을 채택한 경우에는 하부철근받침대(B1)는 단순히 슬래브거푸집(A1)에 접합하기만 하면 된다. 이어 하부철근받침대(B1)에 타이볼트(B3)를 매개로 상부철근받침대(B4)를 연결 설치하는 한편, 경량성형재조립체(100)를 슬래브거푸집(A1) 위로 배치한다. 경량성형재조립체(100)는 그 자체의 자중으로 충분히 놓일 수 있다. 그러고 나서 슬래브상부철근(200)을 상부철근받침대(B4)에 안착시키면서 배근하며, 이때 슬래브상부철근(200)은 결속선(B5)을 묶으면서 상부철근받침대(B4)에 고정한다. 마지막으로 슬래브콘크리트(A3)를 타설한다. 슬래브콘크리트(A3) 타설과정에서 경량성형재조립체(100)는 부상하며, 다만 상향돌기편(130)이 슬래브상부철근(200)에 걸리면서 경량성형재조립체(100)는 더 이상 부상하지 못하고 그 자리에 멈추어 위치하게 되며, 이로써 경량성형재조립체(100)가 슬래브상부철근(200) 아래 이격한 위치에 고정되면서 슬래브에 매입된다. 슬래브콘크리트(A3) 양생으로 중공슬래브가 완성되며, 슬래브거푸집(A1)으로 탈형거푸집을 채택한 경우에는 슬래브거푸집(A1)을 탈형하도록 하며, 슬래브거푸집(A1)으로 존치거푸집을 채택한 경우에는 슬래브거푸집(A1)을 그대로 존치시킨다.Figure 3d shows a process in which the construction structure of the hollow slab according to Figure 3a is applied. First, the lower reinforcing bar (B1) is fixed to the slab formwork (A1) with a fixing nail (B2), and the slab lower reinforcing bar (A2) is seated on the lower reinforcing bar (B1). In the case where the slab formwork (A1) adopts the same formwork as the deck plate, the lower reinforcing bar (B1) simply needs to be joined to the slab formwork (A1). Subsequently, the upper reinforcing bar (B4) is connected to and installed on the lower reinforcing bar (B1) via a tie bolt (B3), and the lightweight molding material assembly (100) is disposed on the slab formwork (A1). The lightweight molding assembly 100 can be fully laid at its own weight. Then, the upper slab upper reinforcement 200 is placed on the upper reinforcing bar (B4) while reinforcing, and the upper slab upper reinforcement 200 is fixed to the upper reinforcing bar (B4) while tying the binding line (B5). Finally, the slab concrete (A3) is poured. In the slab concrete (A3) casting process, the lightweight molding material assembly 100 is injured. However, as the upward protrusion 130 is caught by the upper slab reinforcement 200, the lightweight molding material assembly 100 is no longer injured. It is positioned at the stop, whereby the lightweight molding assembly 100 is embedded in the slab while being fixed at a position spaced below the slab upper reinforcement (200). Hollow slab is completed by curing slab concrete (A3), and when slab formwork is adopted as slab formwork (A1), the slab formwork (A1) must be demolded, and when slab formwork (A1) is adopted as slab formwork (A1) A1) is left as it is.

도 4a 내지 도 4d는 본 발명에 따른 중공슬래브의 시공구조에 대한 제2실시예이다. 제2실시예는 앞서 살펴본 제1실시예와 전반적으로 동일하며, 다만 제1실시예가 경량성형재(120)에 일체형의 상향돌기편(130)이 마련된 것과는 달리, 제2실시예는 경량성형재(120)에 꽂이형의 상향돌기편(130)이 마련된다는 점에서만 차이 가 있을 뿐이다.4a to 4d is a second embodiment of the construction structure of the hollow slab according to the present invention. The second embodiment is generally the same as the first embodiment described above, except that the first embodiment is provided with an integral upward protrusion 130 in the lightweight molding member 120, the second embodiment is a lightweight molding member. There is only a difference in that the upturned piece 130 is provided in the rack type 120.

제2실시예에서 상향돌기편(130)은 도 4b에서와 같이 본체 바닥에 꽂이핀(131)을 구비한 부재로 준비되어 꽂이핀(131)에 의해 경량성형재(120)에 꽂히어 고정 장착된다. 도 4b에서는 일자형의 본체 상부에 오목홈(132)이 형성된 형태의 꽂이형 상향돌기편(130)을 확인할 수 있는데, 오목홈(132)은 슬래브콘크리트(A3)와의 부착력을 증대시키는 역할을 한다. In the second embodiment, the upwardly protruding piece 130 is prepared as a member having a mounting pin 131 at the bottom of the main body, as shown in FIG. 4B, and is fixed to the lightweight molding member 120 by the mounting pin 131. do. In Figure 4b it can be confirmed that the recessed groove 132 is formed in the form of a concave groove 132 formed on the upper portion of the main body, the concave groove 132 serves to increase the adhesive force with the slab concrete (A3).

도 4d는 도 4a에 따른 중공슬래브의 시공구조에 대한 제2실시예가 적용되는 과정을 보여주는데, 보는 바와 같이 앞서 살펴본 제1실시예와 동일한 방식으로 적용된다. 다만 꽂이형의 상향돌기편(130)을 경량성형재(120) 상부면에 꽂는 과정을 더 진행할 필요가 있으며, 꽂이형의 상향돌기편(130)은 슬래브상부철근(200)의 배근위치를 고려하면서 설치하도록 한다.FIG. 4d shows a process in which the second embodiment of the construction structure of the hollow slab according to FIG. 4a is applied, and is applied in the same manner as the first embodiment described above. However, it is necessary to further proceed with the process of inserting the upturned piece 130 of the shelf type into the upper surface of the lightweight molding member 120. The upturned piece 130 of the shelf type considers the reinforcement position of the upper slab of the slab 200. Install it.

도 5a 내지 도 5c는 본 발명에 따른 중공슬래브의 시공구조에 대한 제3실시예이다. 제3실시예는 앞서 살펴본 제1실시예와 전반적으로 동일하며, 다만 제1실시예가 경량성형재조립체(100)와 슬래브상부철근(200) 사이의 간격재를 위해 경량성형재(120)에 일체형의 상향돌기편(130)이 마련된 것과는 달리, 제3실시예는 슬래브상부철근(200)에 착탈형의 하향돌기편(230)이 마련된다.5a to 5c is a third embodiment of the construction structure of the hollow slab according to the present invention. The third embodiment is generally the same as the first embodiment described above, except that the first embodiment is integral with the lightweight molding member 120 for the spacer material between the lightweight molding material assembly 100 and the upper slab upper rebar 200. Unlike the upwardly projecting piece 130 is provided, the third embodiment is provided with a removable downward projection piece 230 of the upper slab upper 200.

제3실시예에서 하향돌기편(230)은 도 5b에서와 같이 슬래브상부철근(200) 하부에 돌출되게 마련되는데, 하향돌기편(230)은 지붕에 철근안착구(231)를 구비한 부재로 준비되어 철근안착구(231)에 의해 슬래브상부철근(200)에 고정 결속된다. 특히 하향돌기편(230)은 철근안착구(231)를 측면 또는 상부가 개구된 탄성클립 형태로 마련하다면 슬래브상부철근(200)의 착탈이 용이하다. 도 5b에서는 측면이 개구된 탄성클립 형태의 철근안착구(231)를 구비한 하향돌기편(230)을 확인할 수 있다. 또한 도 5b에서는 하향돌기편(230)에 타공구멍(232)이 형성된 것을 확인할 수 있는데, 타공구멍(232)은 슬래브콘크리트(A3)와의 부착력을 증대시키는 역할을 한다.In the third embodiment, the downwardly protruding piece 230 is provided to protrude below the slab upper reinforcement 200 as shown in FIG. 5B, and the downwardly protruding piece 230 is a member having a reinforcing seat 231 on the roof. It is prepared and fixed to the upper slab upper reinforcement 200 by the rebar seat 231. In particular, the downwardly protruding piece 230 is easy to attach or detach the slab upper reinforcing bar 200 if the reinforcing seat 231 is provided in the form of an elastic clip with the side or the upper opening. In FIG. 5B, the downwardly protruding piece 230 having the reinforcing seat 231 having an elastic clip shape having an open side surface thereof can be seen.

슬래브상부철근(200)에 하향돌기편(230)이 마련됨에 따라, 중공슬래브의 시공구조에서 슬래브상부철근(200)은 도 5a에서와 같이 하향돌기편(230)이 경량성형재(120)의 수직 상방에 위치하도록 배근된다. 그래야 슬래브콘크리트(A3) 타설과정에서 경량성형재조립체(100)가 부상할 때 경량성형재조립체(100)가 하향돌기편(230)에 걸리면서 그 부상이 억제되며, 이로써 하향돌기편(230)에 의해 경량성형재(120)와 슬래브상부철근(200)의 간격이 유지된다.As the downward protrusion piece 230 is provided in the upper slab upper reinforcement 200, the upper slab upper reinforcement 200 in the construction structure of the hollow slab, as shown in Figure 5a the lower projection piece 230 of the lightweight molding member 120 It is arranged to be positioned vertically upward. Thus, when the lightweight molded assembly 100 is injured in the slab concrete (A3) casting process, the lightweight molded assembly 100 is caught on the downward protrusion 230 and the injuries are suppressed. As a result, the distance between the lightweight molding member 120 and the slab upper rebar 200 is maintained.

도 5c는 도 5a에 따른 중공슬래브의 시공구조가 적용되는 과정을 보여주는데, 보는 바와 같이 앞서 살펴본 제1실시예와 동일한 방식으로 적용된다. 다만 착탈형의 하향돌기편(230)을 슬래브상부철근(200)의 상부에 결속하는 과정을 더 진행할 필요가 있으며, 착탈형의 하향돌기편(230)은 경량성형재조립체(100)의 설치위치를 고려하면서 설치하도록 한다.FIG. 5C shows a process in which the construction structure of the hollow slab according to FIG. 5A is applied, and is applied in the same manner as in the first embodiment as described above. However, the process of binding the detachable downturning piece 230 to the upper portion of the upper slab upper reinforcement 200 needs to proceed further, and the detachable downturning piece 230 considers the installation position of the lightweight molding material assembly 100. Install it.
