Description

기둥 간섭 없이 5대 주차가 가능한 3개층 공작물 주차장 공법{Method of 3-Storey 5-Car Column Free Plant Type Garage}Method of 3-storey 5-Car Column Free Plant Type Garage}

본 발명은 공작물로 분류되는 주차장 중에서 허용되는 지상 높이 8m 내에 주차장법에 맞춰 3단으로 주차하면서 주차장 평면 내에 폭 12m 마다 기둥을 세워 결과적으로는 법정 최소 주차 폭으로 5대씩 기둥 간섭 없이 주차할 수 있게 하는 공법이다.According to the present invention, while parking in three stages according to the parking lot method within the allowed 8m above ground level among the parking lot classified as a work piece, the pillars are built every 12m width in the parking lot plane, and consequently, the vehicle can be parked without the interference of 5 columns at the legal minimum parking width. It is a construction method.

국내 대부분 주차전용건물에서 기둥은 주차통로와 주차공간부의 사이에 기둥을 배열하여 경제성을 도모하고 있다. 즉 법정주차 통로 최소 폭 6m 좌우에 기둥을 세우고 그 후면에 주차공간을 마련함에 있어서 주차공간의 최소 폭 2.3m의 2, 3, 4배수로 기둥을 배치한다. 그러나 본 신청공법은 주차공간을 위 4배수에 한 대를 추가한 5배수로 하고, 주차통로 최소 폭 6m에 1m를 더한 7m 위치에 기둥을 배열하는 획기적 공법을 제공한다.In most domestic parking-only buildings, columns are arranged between the parking passage and the parking space to promote economic feasibility. In other words, the pillars should be placed on the left and right of the minimum width of 6m in the legal parking passage, and the pillars should be arranged in multiples of 2, 3, and 4 times the minimum width of the parking space at 2.3m. However, this application method provides a groundbreaking method of arranging columns at a 7m location with a minimum of 6m in width and a 1m width of the parking path, with the parking space being 5 times with one more than the above 4 times.

주차장법에서 주차통로와 주차공간의 최소 천장높이는 각각 2.3m와 2.1m로 규정하고 있다. 따라서 8m 높이의 공작물을 3등분한 2.66m 층고에 주차통로와 주차공간의 경제성을 부가할 수 있는 보의 최대 높이는 50cm로 한정된다. 이 때 보 단면 직상의 바닥판 최대두께는 6cm가 된다. 그러므로 본 발명에서는 지금까지 발명된 구조공법 중 가장 효율적인 TSC 보(높이50cm)를 배열하여 5대 주차 폭 12m를 확보하고, 이들 보 사이 7m, 4.5m 구간에는 별도 특허출원하는 전용 데크프레이트에 콘크리트를 타설하는 공법을 적용한다. 기둥은 폭이 좁아야 주차하기 편하므로 270mm 폭의 TSC를 사용한 CFT 기둥을 사용한다.According to the parking lot law, the minimum ceiling height of parking paths and parking spaces is 2.3m and 2.1m, respectively. Therefore, the maximum height of a beam that can add the economics of parking path and parking space to the 2.66m height divided into 8m workpieces is divided into 50cm. At this time, the maximum thickness of the bottom plate just above the beam cross-section is 6 cm. Therefore, in the present invention, by arranging the most efficient TSC beam (height 50cm) among the structural methods invented so far to secure five parking widths of 12m, and concrete between the 7m, 4.5m section between the beams to the dedicated deck plate Apply the casting method. The column should be narrow and easy to park, so use a CFT column with a 270mm wide TSC.

주차통로와 주차공간 사이는 기둥이 없는 것이 가장 바람직하나, 차선책으로 12m 간격(법정 주차대수 5대폭)마다 기둥을 세워서 높이제한 8m 내에 3개 층 주차장을 수용하는 것이 본 발명의 과제이다. 기둥과 보는 공장같은 느낌이 드는 H형강 대신 사각형 단면을 사용하고 자동차 이동시 금속성 소음이나 진동이 적은 콘크리트 바닥으로 한다. 시공시 현장운반, 조립하는 단위 구조부재의 길이와 중량을 줄여서 운반차량이나 양중기의 용량을 최소화하고, 공장제작 물량을 늘여서 현장 작업량이 적어지게 하는 것이 품질관리와 인건비 절감에 도움이 된다. 이를 통해 현장작업이 안전하며 공사의 질이 저하되지 않도록 한다.It is most preferable that there is no pillar between the parking passage and the parking space, but it is a problem of the present invention to accommodate a three-story parking lot within 8 meters of height limit by standing pillars at intervals of 12 m (the number of statutory parking spaces) as the next best way. The square section is used instead of the H-beam which feels like a pillar and a factory, and the concrete floor has less metallic noise or vibration when moving a car. It is helpful to reduce quality and labor cost by minimizing the capacity of transport vehicle or lifter by reducing the length and weight of unit structural member to be transported and assembled during construction. This ensures that site work is safe and the quality of construction is not degraded.

일반 철근콘크리트 구조나 H형강 합성구조는 높이 8m의 공작물에 3개 층 주차장을 수용하면서도 연속 5대의 차량을 기둥 간섭 없이 주차하는 경제적인 해결이 불가능하다. 따라서 주차통로와 주차공간사이에 배열할 수 있는 최대높이 50cm의 보(도 2의 G1, G2)로 TSC를 사용하고 주차통로의 폭은 법정 최소치가 6m이지만 7m로 확보하여 차량이동과 주차 시 기둥의 간섭을 최소화 한다. 주차통로의 최소 천장고가 2.3m이므로 12m마다 배열한 기둥(도 2의 C1, C2)을 잇는 보(도 2의 G3, G4)의 높이는 30cm로 하고, 나머지 주차통로와 주차공간에는 별도 특허출원하는 높이 20cm의 깊은 골 데크플레이트(도 3의 D1, D2)를 깔고 그 위와 골에 콘크리트를 타설하는 공법을 사용한다.The general reinforced concrete structure or the H-beam composite structure cannot afford economical solution to park three consecutive parking lots without pillar interference while accommodating a three-story parking lot on an 8-meter-high workpiece. Therefore, the TSC is used as a beam with a maximum height of 50 cm (G1 and G2 in Fig. 2) that can be arranged between the parking passage and the parking space. Minimize interference. Since the minimum ceiling height of the parking passage is 2.3m, the height of the beams (G3, G4 in Fig. 2) connecting the columns arranged every 12m (G1, G4 in Fig. 2) is 30cm, and the remaining parking passages and parking spaces are separately patented. A 20cm high goal deck plate (D1, D2 in Fig. 3) is laid and concrete is placed on and above the bone.

데크플레이트를 깔아도 바닥판의 최소두께를 확보하는 것이 내구성과 차음효과에도 도움이 되므로 예를들어 데크플레이트의 상단을 TSC 보 상단보다 2.5cm 낮게 설치하면 바닥두께 최소치가 7.5cm 확보된다(도 5). 주차통로 폭을 7m로 하고 주차공간을 4.5m로 설계하면 위 데크플레이트를 동일하게 적용할 경우 주차공간 바닥은 비경제적이 된다. 이는 휨모멘트가 바닥길이의 제곱에 비례하며 또한 주차통로의 법적 적재하중이 주차공간보다 크기 때문이다. 그러나 신규 제작하는 데크플레이트를 두 가지 종류로 하면 설비투자비의 부담이 커지게 되므로, 7m 구간은 데크플레이트 내에 철근을 추가한다(D1).Even if the deck plate is laid, securing the minimum thickness of the bottom plate also helps durability and sound insulation. For example, if the top of the deck plate is 2.5cm lower than the top of the TSC beam, the minimum thickness of the floor plate is 7.5cm (Fig. 5). . If the width of the parking passage is 7m and the parking space is designed to 4.5m, the floor space of the parking space becomes uneconomical if the deck plate is applied equally. This is because the bending moment is proportional to the square of the floor length and the legal loading load of the parking passage is larger than the parking space. However, if two types of deck plate is newly manufactured, the burden of facility investment cost increases, so the 7m section adds reinforcing bars to the deck plate (D1).

도 2에서 같은 12m길이의 보라고해도 주차통로 면에 있는 G1은 주차공간 바닥만 지지하는 G2에 비해 하중 부담이 크다. 따라서 G1은 강선으로 보강하여 외관상 같은 형상이 되도록 한다. 공사 도중 골조의 흔들림이나 변형을 제어하고 완공 후 바람, 지진 등 횡력 저항력을 확보하기 위하여 데크플레이트 설치 방향으로도 기둥 사이에 최소규격(높이 30cm)의 TSC 보(G3, G4)를 추가한다.Even in the same 12m length in Figure 2 G1 on the side of the parking path has a greater load burden than G2 supporting only the floor of the parking space. Therefore, G1 is reinforced with a steel wire so as to have the same shape in appearance. TSC beams (G3, G4) of minimum size (30cm in height) are added between the columns in the direction of deck plate installation to control the shaking or deformation of the frame during construction and to secure the lateral force resistance such as wind and earthquakes after completion.

높이 8m로 제한되는 공작물에 3개 층의 주차장을 설계함에 있어 주차통로와 주차공간 사이에 기둥을 12m마다 배치하여 5명의 운전자가 기둥 간섭 없이 쉽게 주차 및 출차를 할 수 있게 한다. 또한 소음 진동이 해소되고 미관상에도 지장이 없는 주차공작물이다.In designing a three-story parking lot on a workpiece limited to 8 meters in height, columns are placed every 12 meters between the parking passage and the parking space, allowing five drivers to park and unload easily without interference. It is also a parking work that eliminates noise and vibration and does not interfere with aesthetics.

공작물에 적용하는 철골구조의 보편적인 소재는 H형강이다. 그러나 H형강은 그 외형이 상하 수평 플랜지를 중앙에서 수직 웨브가 붙들어주는 것이므로 데크플레이트를 상부 플랜지에 얹어서 사용하는 일반 공법에서는 별 문제가 없으나 본 공작물에서와 같이 제한된 높이에서 보의 효율을 극대화하는 데는 무리가 있다. 즉 데크플레이트를 사용하는 바닥판 두께의 일부가 보의 상부 플랜지 밑으로 내려오게 하는 방법은 상부 플랜지 하부 웨브 부분에 별도의 날개를 달아 상부 플랜지 돌출 폭 보다 더 길게 돌출시켜야 하는 어려움이 있다(도 6 ∼10).The common material of steel structure applied to workpieces is H-beam. However, since the shape of the H-beams is held vertically by vertical webs at the top and bottom horizontal flanges, there is no problem in the general method where the deck plate is mounted on the upper flange, but it is not necessary to maximize the efficiency of the beam at the limited height as in this work piece. There is a group. That is, a method of causing a part of the thickness of the bottom plate using the deck plate to descend below the upper flange of the beam has a difficulty of protruding longer than the upper flange protrusion width by attaching a separate wing to the lower web portion of the upper flange (FIG. 6). To 10).

TSC 보는 이러한 문제점을 해결하기 용이한 구조이다. TSC 보는 단면 외관이 철근콘크리트 보와 같아서 좌우 웨브플레이트에 고리만 부착하면 상기 고리에 데크플레이트를 얹어서 바닥판을 조성할 수 있다. 또한 TSC 보는 일반 H형강 합성보에 비해 30% 정도의 경제성을 갖는다. TSC를 이용하여 8m 높이의 공작물에 3개 층의 주차장을 건설하기 위한 공사순서는 아래와 같다.The TSC beam is an easy structure to solve this problem. TSC beams have the same cross-sectional appearance as reinforced concrete beams, so that only the hooks are attached to the left and right webplates so that the deck plate can be placed on the hooks to form a bottom plate. In addition, TSC beams are 30% more economical than conventional H-beam composite beams. The construction procedure for building a three-story parking lot on an 8-meter-high workpiece using TSC is as follows.

1. 도 2와 같이 기초 상부에 C1, C2를 세운다. 8m 높이에 3개 층을 설치하기 위해 기둥 C1, C2는 500×270×9t인 TSC로 하며 각 층에 보를 부착하는 패널 존(Panel Zone) 내부에는 공장에서 앵커볼트를 사전 부착하고 TSC의 열린 부분에 강판을 부착하여 외관상 일자형을 이루게 한다(도 4). 기둥의 방향은 주차통로에 면하는 폭이 270mm가 되게 하여 주차공간 활용도를 극대화한다.1. Set C1, C2 on the top of the foundation as shown in FIG. Columns C1 and C2 are TSCs of 500 × 270 × 9t to install three floors at 8m height. Anchor bolts are pre-attached at the factory inside the panel zone where beams are attached to each floor. Attach the steel plate to form a straight in appearance (Fig. 4). The direction of the pillar is 270mm wide to face the parking passage to maximize the utilization of the parking space.

2. 각층 보 G1, G2, G3, G4를 C1, C2에 부착하고, 16m 폭 중 중앙부의 큰 보(G1)는 공장에서 강선으로 보강하여 제작한다(별도 특허출원중).2.
