In the present invention, when constructing a rooftop sculpture, a PC support such as a PC wall or a PC pillar and a PC member such as a gelber-beam or a PC slab are integrally coupled to each other, and the PC member is etched inwardly at an end thereof. Synthetic grooves are formed, but the bolts are formed in the composite grooves are pre-filled and formed in the form of joints, so that a separate steel plate is simply fastened and coupled to the PC support, eliminating the insert-type anchor bolt installation compared to the previous (Deleted) It is possible to reduce the production cost (material cost), while precise construction is possible by securing the precise protrusion length of the bolt, and assembling and conveying transportation is secured to solve the problem of loss of the existing fasteners (bolts, nuts) as well as construction assembly. It is designed to make the worker easy and simple in the field work, especially the joint and PC support formed on the PC member By forming a unitary structure binding by a simple construction, it relates to a PC bonded structure of the rooftop sculpture, characterized in that the construction, durability and structural stability compared to the past improved.

일반적으로 공동주택이나 상업건축물 등의 옥상에는 건축물의 미관을 향상시키기 위한 조형물 내지 장식물이나 엘리베이터 샤프트의 옥탑지붕층(이하 '옥상 조형물'이라 한다) 등이 시공된다.In general, sculptures or decorations for improving aesthetics of buildings or rooftop roof layers (hereinafter referred to as 'roof sculptures') for improving aesthetics of buildings are constructed on rooftops of apartment houses or commercial buildings.

이에 종래의 옥상 조형물은 보통 그 아래층의 본 구조물과 마찬가지로 거푸집을 대고 동바리로 지지한 후 콘크리트를 현장 타설하여 시공된다. Therefore, conventional rooftop sculptures are usually constructed by placing concrete on the site after supporting the formwork with the formwork as in the lower structure.

이 경우 옥상까지 콘크리트를 운반해야 하는 어려움이 있고, 아래층의 본 구조물 공사의 공정과 간섭을 일으킬 우려가 있어 공정관리가 곤란한 문제점이 있다.In this case, there is a difficulty in transporting the concrete to the rooftop, and there is a problem that it may cause interference with the process of the construction of the main structure below, there is a problem that the process management is difficult.

또한, 미관을 위해 건축물의 외벽으로부터 돌출되게 되는 옥상 조형물의 지붕층을 시공하는 경우 거푸집 설치 공정이 매우 어렵고 위험한 문제가 있다.In addition, in the case of constructing the roof layer of the roof sculpture that protrudes from the outer wall of the building for aesthetics, the formwork installation process is very difficult and dangerous problem.

이러한 점을 감안하여 최근에는 옥상 조형물을 피씨(PC, Precast Concrete)로 시공하는 경우가 있으며, 특히 옥상 조형물의 지붕의 경우 피씨로 하는 경우가 많이 있다. In view of this, roof sculptures have recently been constructed with PC (precast concrete), and in particular, roofs of roof sculptures have many cases.

그러나 피씨(PC)로 지붕을 구성할 경우 두께 및 크기가 상당히 커서 타워크레인으로 양중이 가능하도록 여러 부재로 분할해야 할 필요성이 있고 그에 따라 피씨 지붕판 간의 연결부에서 하자가 발생되는 경우가 많다. However, when the roof is made of PC, the thickness and size are so large that it is necessary to divide it into several parts so that it can be lifted by the tower crane. Therefore, defects are often generated at the connection between the PC roof plates.

따라서, 벽체와 지붕판 간의 일체성을 확보하기 위한 접합부의 상세를 고려해야 할 필요가 있다.Therefore, it is necessary to consider the details of the joint to secure the integrity between the wall and the roof board.

이에, 종래의 접합부를 보다 자세히 살펴보면, 도 5에 도시된 바와 같이 PC부재의 단부에 결합되어 이웃한 타측 PC부재와 결속을 도모하기 위한 조인트(10)가 개시되어 있는 바, 이러한 조인트(10)는 철판(11)의 저면에 인서트형 앵커볼트(12)와 앵커 바(13)가 형성되어 PC부재의 내부에 매립되도록 하되, 상기 철판의 면상에는 인서트형 앵커볼트와 대응되도록 통공(14)이 형성되어 별도의 볼트(15)와 너트(16)가 차례로 끼워져 조립되도록 형성된다.Thus, when looking at the conventional joint in more detail, as shown in Figure 5 is coupled to the end of the PC member is disclosed for the joint 10 to bond with the neighboring other PC member bar, such a joint 10 Insert type anchor bolt 12 and the anchor bar 13 is formed on the bottom surface of the iron plate 11 to be embedded in the PC member, the through hole 14 to correspond to the insert type anchor bolt on the surface of the iron plate Is formed is formed so that the separate bolt 15 and the nut 16 is fitted in order to be assembled.

이때, 상기 너트(16)와 철판(11)의 상면 사이에는 이웃한 조인트와 연결 조립되도록 이음판(미도시)이 형성되어 복수의 PC부재를 서로 결속하도록 형성된다.At this time, a joint plate (not shown) is formed between the nut 16 and the upper surface of the iron plate 11 so as to be assembled and coupled with a neighboring joint, and is formed to bind the plurality of PC members to each other.

그러나, 이와 같은 종래의 조인트는 인서트형 앵커볼트가 PC부재에 매립된 상태에서 운반 또는 설치됨으로써, 나사산이 형성된 내부 공간으로 콘크리트 페이스트 또는 이물질이 유입되어 현장에서 이를 제거하기 번거로움은 물론 겨울철 또는 장마철과 같은 계절에는 눈 또는 성애로 인한 얼음이 형성되어 이를 제거하면서 작업하기 곤란한 문제가 계속되었는 바, 이는 시공성과 작업성이 크게 저하되는 문제가 발생되고 있는 실정이다.However, such a conventional joint is carried or installed in a state where the insert-type anchor bolt is embedded in the PC member, so that concrete paste or foreign material is introduced into the threaded internal space, and it is troublesome to remove it in the field as well as in winter or in the rainy season. In the season, such as the ice formed by snow or sex formed a problem that is difficult to work while removing it, which is a problem that the construction and workability is greatly reduced.

또한, 종래의 조인트는 철판의 저면에 하나 이상의 앵커 바를 용접하도록 함으로써, 용접비용 추가로 인한 원가상승과 공기지연이 계속해서 발생되는 문제가 있어 왔다.
In addition, the conventional joint has a problem that the cost increase and air delay caused by the additional welding cost by continuously welding at least one anchor bar on the bottom of the iron plate has been a problem.

본 발명은 상술한 문제점을 해결하기 위한 것으로, 옥상 조형물을 시공함에 있어서, 피씨벽 또는 피씨기둥과 같은 PC지지체와 겔버-보 또는 피씨 슬래브와 같은 PC부재가 걸침된 후 일체화로 결합되도록 하는 것으로, 상기 PC부재는 단부에 내측으로 식각된 합성홈이 형성되되, 상기 합성홈에는 기 매립되어 양생된 볼트 분기형 조인트가 형성되어 별도의 스틸판으로 하여금 PC지지체와 간단히 체결 결합되도록 함으로써, 종전 대비 인서트형 앵커볼트 설치가 생략(삭제)되어 제작비(재료비)의 절감을 도모하는 한편, 볼트의 정확한 돌출길이 확보로 인해 정밀 시공이 가능하고, 가조립 운반 이송이 확보되어 기존 체결구(볼트, 너트)의 분실 문제를 해결함은 물론 시공 조립시 작업자로 하여금 현장 작업성이 용이하고 간편하도록 형성되며, 특히 PC부재에 형성된 조인트와 PC지지체는 조립용 주근에 의해 일체형 구조 결속을 이루되 간단히 시공되도록 함으로서, 종전 대비 시공성, 내구성 및 구조 안정성이 향상되는 것을 특징으로 하는 옥상 조형물의 피씨 접합 구조를 제공함에 그 목적이 있다.
