Description

하프ＰＣ슬래브의 이음구조{Joint of half PC slab}Joint structure of half PC slab {Joint of half PC slab}

본 발명은 하나의 스팬 내에 설치되는 복수개의 하프PC슬래브 상호 간 이음구조에 관한 것으로, 더욱 상세하게는 보강부재의 설치길이를 줄여 시공성을 확보하면서도 이음부의 휨성능을 충분히 만족시킬 수 있는 하프PC슬래브의 이음구조에 관한 것이다.The present invention relates to a joint structure between a plurality of half PC slabs installed in one span, and more particularly, a half PC slab that satisfies the bending performance of the joint part while securing construction properties by reducing the installation length of the reinforcing member. It is about the joint structure of.

콘크리트 슬래브를 시공하는 방식에는 거푸집을 설치하여 현장에서 직접 콘크리트를 타설하는 현장시공법과, 공장에서 제작된 PC(precast concrete)부재를 현장에서 조립하여 설치하는 PC공법으로 구분할 수 있다. 현장시공법은 많은 현장작업량에 따라 많은 인력과 공기(工期)가 소요되므로, 최근에는 부재의 표준화, 공정의 간소화, 노동 생산성 등을 꾀할 수 있는 PC공법이 주목받고 있는 상황이다.The method of constructing the concrete slab can be divided into the field construction method of placing concrete directly at the site by installing formwork, and the PC method of assembling and installing precast concrete (PC) members manufactured at the factory. Since the site construction method requires a lot of manpower and air according to the amount of work on site, the PC method that can achieve the standardization of members, the process simplification, labor productivity, etc. has been attracting attention recently.

PC공법에는 다양한 형태의 PC부재들이 개발되어 사용되고 있으며, 그러한 PC부재 중의 하나가 하프PC슬래브이다. 하프PC슬래브는 양중무게를 고려하여 소요 슬래브 두께의 절반 정도의 두께로 미리 공장에서 제작한 부재인데, 통상적으로 하 부철근 다수개를 병렬 배치한 후 상·하현재와 래티스재가 조립된 트러스조립철근 다수개를 병렬 배치하여 하부철근 위에 교차하게 접합한 상태에서 콘크리트를 부어 하부철근이 콘크리트에 매입되도록 하는 한편 트러스조립철근 상부가 콘크리트에서 돌출되도록 제작한다. 이와 같은 하프PC슬래브는 시공위치에 양중 설치한 후에 나머지 콘크리트를 현장에서 타설하여 슬래브 구조체로 완성된다.Various types of PC members have been developed and used in the PC method, and one of such PC members is a half PC slab. The half PC slab is a factory manufactured member that is about half the thickness of the required slab in consideration of the weight of the weight.Truss-assembled reinforcing bars, in which upper and lower chords and lattice materials are assembled after placing several lower rebars in parallel Plural concrete is placed in parallel and placed on the bottom of the rebar to pour the concrete so that the bottom of the rebar is embedded in the concrete, while the top of the truss assembly reinforcement is manufactured to protrude from the concrete. Such a half PC slab is installed in the construction position in both places, and then the remaining concrete is poured on site to complete the slab structure.

한편, 하프PC슬래브의 운반과 양중 등 전반적인 사정을 고려할 때 하프PC슬래브는 그 폭이 제한되기 마련이며, 이러한 하프PC슬래브를 이용하여 슬래브 공사를 수행한다면 하나의 스팬 내에 여러 개의 하프PC슬래브를 맞대어 설치해야만 하는 경우가 있을 수밖에 없다. 이 경우 하프PC슬래브 상호 간 맞댄이음부는 전단 내지 휨 등 구조적으로 취약하므로 이에 대한 고려가 필요한데, 전단성능은 하프PC슬래브 위에 상부철근(전단철근으로 역할함)을 배근하는 것으로, 휨성능은 하프PC슬래브에 근접하게 보강부재를 설치하는 것으로 확보할 수 있다.On the other hand, considering the overall circumstances such as transportation and lifting of the half PC slab, the width of the half PC slab is limited, and if the slab construction is carried out using such a half PC slab, several half PC slabs may be faced in one span. There must be a case to install. In this case, butt joints between the half PC slabs are structurally fragile such as shearing or bending, so consideration is required. Shearing performance is to reinforce the upper reinforcing bar (same as shear bar) on the half PC slab. This can be ensured by providing a reinforcing member close to the PC slab.

도 1 및 도 2는 종래의 하프PC슬래브 이음구조로서, 보강부재로 통상적인 철근을 채택하여 이를 하프PC슬래브의 맞댄이음부에 설치함으로써 맞댄이음부의 휨성능을 보강한 예를 보여준다. 도시하고 있는 바와 같이 보강부재(철근)는 이음방향으로 배근되며, 다만 충분한 휨성능을 확보하기 위해서는 보강부재(철근)의 충분한 설치길이(충분한 정착력 확보를 위한 설치길이)가 필요하다. 그런데, 보강부재(철근)을 충분한 설치길이로 설치하는 것은 그리 쉽지 않다. 왜냐하면 보강부재(철근)와 하프PC슬래브의 트러스조립철근 사이에 간섭이 일어나기 때문이다. 다시 말 해, 보강부재(철근)는 하프PC슬래브의 트러스조립철근과 교차하게 배근되는데, 이 경우 보강부재(철근)가 트러스조립철근의 래티스근에 걸리기 때문에 보강부재(철근)을 배근하기 위해서는 간섭부위의 래티스근을 일일이 절단해야 하는 번거로운 현장작업을 수행해야 하는 바, 보강부재(철근)의 설치길이가 길수록 그 현장작업량은 많아질 수밖에 없는 것이다.1 and 2 show a conventional half PC slab joint structure, which adopts a conventional reinforcing bar as a reinforcing member and installs it in the butt joint of the half PC slab to reinforce the bending performance of the butt joint. As shown, the reinforcing member (rebar) is reinforced in the joint direction, but in order to secure sufficient bending performance, sufficient installation length of the reinforcing member (rebar) (installation length for securing sufficient fixing force) is required. By the way, it is not so easy to install the reinforcing member (rebar) with sufficient installation length. This is because interference occurs between the reinforcing member (bar) and the truss assembly bar of the half PC slab. In other words, the reinforcing member (rebar) is reinforced to cross the truss reinforcing bar of the half PC slab. In this case, the reinforcing member (rebar) is caught by the lattice reinforcing bar of the truss reinforcing bar. The cumbersome field work to cut the lattice muscles of the site must be performed one by one, the longer the installation length of the reinforcing member (reinforcing bar) will have to increase the amount of field work.

특히나 슬래브 경량화를 위해 하프PC슬래브에 중공재를 설치할 수 있는데, 이 경우에는 보강부재(철근)가 중공재와도 간섭이 일어나게 된다. 이러한 간섭문제는 도 2와 같이 간섭위치의 중공재를 제거하는 방법으로 해결할 수밖에 없으나, 중공재를 제거하면 그만큼 콘크리트 타설량을 증대시켜야 하기 때문에 슬래브 경량화 효과는 그만큼 떨어진다.In particular, a hollow material may be installed in the half PC slab to reduce the weight of the slab. In this case, the reinforcing member (rebar) will also interfere with the hollow material. This interference problem can not only be solved by the method of removing the hollow material at the interference position as shown in FIG. 2, but when the hollow material is removed, the slab lightweighting effect is inferior to that of the 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 3 내지 도 9는 본 발명에 따른 하프PC슬래브의 이음구조에 대한 다양한 실시예를 보여준다. 본 발명에 따른 하프PC슬래브의 이음구조는, 하나의 스팬 내에 설치되는 복수개의 하프PC슬래브 상호 간 이음구조로서, 서로 맞대어 설치되는 제1,2하프PC슬래브(100, 200)와 제1,2하프PC슬래브의 맞댄이음부에 설치되는 보강부재(310, 320, 330, 340) 및 제1,2하프PC슬래브 위로 보강부재가 매입되도록 타설되는 토핑콘크리트를 기본적인 구성으로 한다. 본 발명에서는 상기 보강부재(310, 320, 330, 340)의 형태와 제1,2하프PC슬래브(100, 200) 상호간의 맞댄이음부의 형성방법에 따라 다양한 실시예로 구분하여 제안하고 있다.3 to 9 show various embodiments of the joint structure of the half PC slab according to the present invention. The joint structure of the half PC slab according to the present invention is a mutual joint structure of a plurality of half PC slabs provided in one span, and the first and second half PC slabs 100 and 200 and the first and second half PC slabs are installed to face each other. Reinforcing members (310, 320, 330, 340) provided on the butt joint portion of the half PC slab and the topping concrete is placed so that the reinforcing member is embedded over the first and second half PC slab as a basic configuration. In the present invention, the reinforcing member 310, 320, 330, 340 and the first and second half PC slab (100, 200) according to the formation method of the butt joint between each other are divided into various embodiments are proposed.

본 발명에서 제1,2하프PC슬래브(100, 200)는 종래의 하프PC슬래브와 마찬가지로 제작되어 준비된다. 다시 말해, 제1하프PC슬래브(100)는 제1하부철근(110) 다수개가 병렬 배치되고 상·하현재와 래티스재가 조립된 제1트러스조립철근(120) 다수개가 병렬로 제1하부철근(110) 위에 교차하게 배치되어 접합된 상태에서, 상기 제1하부철근(110)이 콘크리트에 매입되는 한편 상기 제1트러스조립철근(120) 상부가 콘크리트를 돌출하도록 제작된 것이다. 물론, 제2하프PC슬래브(200)는 제2하부철근(210)과 제2트러스조립철근(220)을 포함하여 제1하프PC슬래브(100)와 동일한 구조로 제작된 것이다. 상기 제1,2하프PC슬래브(100, 200)에서 제1,2트러스조립철근(120, 220)은 1본의 상현재와 1본의 하현재로 구성된 평면트러스조립철근은 물론 1본의 상현재와 2본의 하현재로 구성된 입체트러스조립철근도 포함하며, 다만 본 발명에서는 실시예를 통해 입체트러스조립철근을 채택하고 있다.In the present invention, the first and second half PC slabs 100 and 200 are manufactured and prepared as in the conventional half PC slab. In other words, in the first half PC slab 100, a plurality of first truss assembly reinforcing rods 120 in which a plurality of first lower reinforcing bars 110 are arranged in parallel and upper and lower chords and a lattice material are assembled in parallel with the first lower reinforcing bars ( In a state in which the joints are arranged to cross each other, the first lower reinforcement 110 is embedded in concrete while the upper portion of the first truss assembly reinforcement 120 protrudes from the concrete. Of course, the second half PC slab 200 is manufactured in the same structure as the first half PC slab 100 including the second lower reinforcement 210 and the second truss assembly reinforcement 220. In the first and second half PC slab (100, 200), the first and second truss assembly reinforcement (120, 220) is a flat truss reinforcing bar consisting of one top chord and one bottom chord, as well as one image Also included is a three-dimensional truss assembly reinforcing bar consisting of the present and two lower chords, but the present invention adopts a three-dimensional truss assembly reinforcing bar through the embodiment.

특히, 슬래브의 경량화를 위해서 슬래브 내부에 중공재(경량성 부재)를 매입시켜 중공슬래브로 완성할 수 있는데, 이러한 중공슬래브를 위해서라면 상기 제1,2하프PC슬래브(100, 200) 각각은 각각의 제1,2트러스조립철근(120, 220) 사이에 중공재(130, 230)를 배치하여 중공재(130, 230)가 콘크리트를 돌출하도록 제작함이 바람직하다. 이때 중공재(130, 230)는 막대형 중공재는 물론 단위블록형 중공재를 채택할 수 있으며, 다만 본 발명에서는 실시예를 통해 단위블록형(직육면체형) 중공재를 채택하고 있다.Particularly, in order to reduce the weight of the slab, a hollow material (lightweight member) may be embedded in the slab and completed as a hollow slab. For the hollow slab, each of the first and second half PC slabs 100 and 200 may be respectively. It is preferable to arrange the hollow material (130, 230) between the first and second truss assembly reinforcing bars (120, 220) of the hollow material (130, 230) to protrude concrete. At this time, the hollow material (130, 230) can be adopted in the unit block-type hollow material as well as the rod-shaped hollow material, but in the present invention, the unit block type (cuboid-shaped) hollow material is adopted through the embodiment.

상기와 같이 제작된 제1,2하프PC슬래브(100, 200)는 슬래브 시공위치에 서로 맞대어 설치되며, 그 맞댄이음부 위로 보강부재(310, 320, 330, 340)를 설치한 후 동시에 토핑콘크리트를 타설하면 보강부재가 토핑콘크리트에 구속되어 휨성능을 발휘하게 된다. 이때 상기 제1,2하프PC슬래브(100, 200)가 단부 모서리가 모따기되 도록 제작된 것이라면 상기 제,2하프PC슬래브(100, 200)는 맞댄이음부에 모따기홈(G1)을 형성시키면서 설치되는데, 이러한 모따기홈(G1)에는 토핑콘크리트가 충진되어 맞댄이음부에서의 휨성능은 증대된다.The first and second half PC slabs 100 and 200 manufactured as described above are installed to face each other at the slab construction position, and at the same time after installing the reinforcing members 310, 320, 330 and 340 on the butt joints, When scooping up, the reinforcing member is constrained to the topping concrete to exhibit the bending performance. In this case, if the first and second half PC slabs 100 and 200 are manufactured so that the end edges are chamfered, the first and second half PC slabs 100 and 200 are installed while forming a chamfer groove G1 in the butt joint portion. The chamfering groove (G1) is filled with topping concrete, the bending performance at the butt joint is increased.

The joint structure of FIGS. 3 to 6 prepares hook reinforcing bars 310, which are bent by hooks with the upper ends of the reinforcing bars, and the first and second lower reinforcing bars of the first and second half PC slabs. After installation in parallel with each other in the same direction as (110, 210), it is completed by pouring topping concrete. In the completed joint structure as described above, the bending performance is exhibited by the restraint force of the hook reinforcement 310 and the topping concrete. In particular, the hook reinforcement 310 is preferably installed on the same line as the first and second lower reinforcing bars 110 and 210 of the first and second half PC slabs. It is to increase the bending performance by securing the continuity between the lower reinforcement (110, 210) and the hook reinforcement 310, and further, the first and second truss assembly reinforcement of the first and second half PC slab If the binding to the (120, 220) or installed to hang will increase the restraint of the hook reinforcement 310 will be more powerful bending resistance.

도 3이 갈고리철근(310)을 채택한 경우의 가장 기본적인 예라면, 도 4 내지 도 6은 맞댄이음부의 휨성능을 더욱 보강한 예이다. 도 4는 제1,2하프PC슬래브(100, 200)로 맞댄이음부에 위치한 제1,2하부철근(110, 210)의 단부가 상향하여 갈고리로 절곡된 채 콘크리트를 돌출하도록 제작된 것을 채택한 예로서, 제1,2하부 철근(110, 210)의 갈고리를 토핑콘크리트에 매입되도록 함으로써 휨보강하고 있다. 도 5는 제1,2하프PC슬래브(100, 200)로 단부가 얇은 두께의 낮은턱으로 형성되도록 제작된 것을 채택한 예로서, 이와 같은 제1,2하프PC슬래브(100, 200)를 설치하면 맞댄이음부에 낮은턱홈(G2)이 형성되는데 갈고리철근(310)을 상기 낮은턱홈(G2)에 위치하도록 설치하여 갈고리철근(310)의 설치위치를 아래로 내린 상태에서 토핑콘크리트에 매입되도록 함으로써 휨보강하고 있다. 도 6은 도 4와 도 5의 방법을 함께 적용하여 휨보강한 예이다. 3 is the most basic example in the case of adopting the hook reinforcement 310, Figures 4 to 6 is an example to further strengthen the bending performance of the butt joint. FIG. 4 adopts the first and second lower reinforcing bars 110 and 210 positioned at the butt joints of the first and second half PC slabs 100 and 200 to protrude concrete while being bent upwardly by hooks. For example, flexural reinforcement is performed by allowing the hooks of the first and second lower reinforcing bars 110 and 210 to be embedded in the topping concrete. FIG. 5 is an example in which the first and second half PC slabs 100 and 200 are manufactured so that their ends are formed with a low thickness of the lower jaw, and the first and second half PC slabs 100 and 200 are installed. The lower jaw groove G2 is formed in the butt joint, and the hook reinforcement 310 is installed in the lower jaw groove G2 so as to be buried in the topping concrete while the installation position of the hook reinforcement 310 is lowered. Reinforcing 6 is an example of flexural reinforcement by applying the method of FIGS. 4 and 5 together.
