Description
본 발명은 더블월 내외측 패널의 내부에 합성부재를 설치하여 내외측 패널 합성 매개체 역할과 패널간 간격유지를 할 수 있도록 하고 철근 설치 위치 오차와 피복 두께 오차 발생 배제로 접합부 성능 확보가 가능하며 더블월 설치 후 접합부 내부를 보강하는 철근 배근 최소화로 현장작업이 간결화되며, 연속되게 설치된 더블월 접합부 합성 효과 증대와 운반 및 가설 시 외부 충격에 저항하여 단면형상 유지하도록 하는 프리캐스트 콘크리트 내외측 패널에 설치된 합성부재로 접합부 합성성능을 개선한 더블월, 이의 제작방법 및 이를 이용한 더블월 시공방법에 관한 것이다.The present invention relates to a double wall, a method for manufacturing the same, and a double wall construction method using the same, in which a synthetic member is installed inside the inner and outer panels of a double wall to serve as a composite medium for the inner and outer panels and to maintain the gap between the panels, and thereby secures joint performance by eliminating errors in reinforcing bar installation positions and errors in covering thickness, and simplifies on-site work by minimizing reinforcement arrangement for reinforcing the inside of the joint after double wall installation, and thereby improves the joint composite performance by installing the synthetic member on precast concrete inner and outer panels to increase the composite effect of the continuously installed double wall joint and to maintain the cross-sectional shape by resisting external impact during transportation and erection.
일반적으로 프리캐스트 콘크리트 구조물인 더블월은 내외측 패널을 미리 제작하여 현장에서 연속하여 설치하는 공법으로 합성효과를 구현하는 더블월 접합면의 유효단면은 더블월 총 단면이 아닌 더블월 내외측 패널의 단면을 제외한 콘크리트 타설 구간만이 유효단면으로 적용하여 전단이나 휨에 대한 저항성능이 떨어져 접합부 성능 구현을 위한 보강이 필요하며, 접합부 단면성능 부족으로 외력 작용 시 더블월 접합부 균열, 단차 등이 발생할 수 있어 확실한 접합부 합성으로 단면성능 향상 방안 필요하다.Double walls, which are generally precast concrete structures, are a method of fabricating inner and outer panels in advance and installing them continuously on site. The effective cross-section of the double wall joint that implements the composite effect is not the total cross-section of the double wall, but only the concrete pouring section excluding the cross-sections of the inner and outer panels of the double wall is applied as the effective cross-section, so the resistance performance to shear or bending is low, and reinforcement is required to implement the performance of the joint. In addition, cracks and differences in the double wall joint may occur when an external force is applied due to insufficient cross-sectional performance of the joint, so a method to improve the cross-sectional performance through reliable joint synthesis is necessary.
또한, 일반적인 더블월 시공 시 더블월을 연속 설치하고 접합부 보강을 위한 철근망을 설치하는데 건설장비를 이용한 작업으로 정밀한 설치가 힘들고 연성재료인 철근의 변형으로 내외측 패널 사이에서 어떻게 배치되어 있는지 확인이 어려워 철근망 설치 위치 오차 및 피복 두께 오차가 발생하는 문제가 있으며, 철근망의 배치 오류 발생 시 단면성능 부족으로 더블월 접합부 균열, 부재간의 단차, 배부름 현상 등이 발생한다.In addition, during general double wall construction, double walls are installed continuously and reinforcing mesh is installed to reinforce the joints. This makes precise installation difficult because construction equipment is used for the work. In addition, it is difficult to confirm how the reinforcing steel, which is a ductile material, is arranged between the inner and outer panels due to deformation, which causes errors in the installation location of the reinforcing steel and errors in the thickness of the covering. In addition, when errors in the arrangement of the reinforcing steel, cracks in the double wall joints, differences in steps between members, and bulging occur due to insufficient sectional performance.
또한, 현장에서 철근망을 구현하기 위한 철근 가공조립 공정이 발생하여 제작장 및 야적장 확보를 위한 추가 비용 발생하고, 철근망 설치 시 건설장비 가설로 부재 내부의 좁은 공간에 정밀하게 설치해야 하므로 공사 기간이 늘어나는 문제가 있다.In addition, there is a problem that the construction period is extended because the steel bar processing and assembly process to implement the steel bar mesh on site occurs, resulting in additional costs for securing a production site and storage yard, and because the steel bar mesh must be installed precisely in a narrow space inside the member due to the installation of construction equipment.
이와 같은, 철근망의 오류를 줄이기 위하여 선 설치된 더블월에 철근망을 설치한 후 연속되게 더블월을 설치할 경우 더블월의 수평 및 수직 이동 시 철근망과 접촉되지 않게 정밀한 가설이 필요하여 공사 기간이 늘어나는 문제가 있으며, 철근망 삽입시 정확하게 설치되지 않을 경우 위치 조정을 위한 움직임으로 더블월 고정 버팀대에 움직임이 발생하여 더블월 전도의 위험성이 높아지는 문제가 있다.In order to reduce errors in the reinforcing bar mesh, when installing reinforcing bar mesh on a pre-installed double wall and then continuously installing the double wall, precise installation is required to avoid contact with the reinforcing bar mesh when the double wall moves horizontally and vertically, which increases the construction period. In addition, when the reinforcing bar mesh is not installed accurately, movement occurs in the double wall fixing brace for positioning adjustment, which increases the risk of the double wall toppling.
본 발명의 배경이 되는 기술로는 특허등록 제2453791호 "보강 돌출부 및 연결 플레이트를 이용한 피씨 더블월"(특허문헌 1)가 있다. The technology that serves as the background for the present invention is Patent Registration No. 2453791, “PC double wall using reinforcing protrusion and connecting plate” (Patent Document 1).
상기 배경기술에서는 내부에 철근망이 매립되어 구성되고, 후면에서 폭방향 일정거리 이격되도록 2개 이상의 보강 돌출부가 돌출되어 형성되는 전면 피씨 패널과; 내부에 철근망이 매립되어 구성되고, 후면에서 폭방향 일정거리 이격되도록 2개 이상의 보강 돌출부가 돌출되어 형성되며, 전면 피씨 패널과 일정거리 이격되어 평행하게 위치하는 후면 피씨 패널과; 전면 피씨 패널의 보강 돌출부와 후면 피씨 패널의 보강 돌출부를 연결하도록 단부가 보강 돌출부에 매입되어 구성되며 높이방향 일정 간격마다 형성되는 일정 크기 수직 판 형상의 연결플레이트와; 원기둥 형상으로 하부면에서 상부로 일정 높이까지 형성되며 내주면에 나사산 가공되는 결합구가 형성되는 홀더와, 홀더의 상부에 수직방향으로 결합되는 상부철근으로 이루어지며, 홀더의 하부면이 노출되도록 전면 피씨 패널과 후면 피씨 패널의 보강 돌출부가 형성되는 하부면에 매입되는 커플러;를 포함하여 이루어지도록 하여, 생산비용을 절감할 수 있으면서도 측압 및 인양하중에 저항하고 강성을 유지할 수 있어 더블월의 폭을 증대시킬 수 있도록 한다.In the above background technology, a front PC panel is formed by embedding a reinforcing bar mesh inside and having two or more reinforcing protrusions protruding from the rear so as to be spaced apart from each other in the width direction at a certain distance; a rear PC panel is formed by embedding a reinforcing bar mesh inside and having two or more reinforcing protrusions protruding from the rear so as to be spaced apart from each other in the width direction at a certain distance and positioned parallel to the front PC panel at a certain distance; a connecting plate in the shape of a vertical plate of a certain size formed at a certain interval in the height direction so as to connect the reinforcing protrusion of the front PC panel and the reinforcing protrusion of the rear PC panel, the ends of which are embedded in the reinforcing protrusions; The double wall is formed by including a coupler embedded in the lower surface, which is formed from a holder formed from a lower surface to an upper surface to a certain height in a cylindrical shape and has a screw-threaded joint formed on the inner surface, and an upper reinforcing bar vertically joined to the upper surface of the holder, and a reinforcing protrusion of the front PC panel and the rear PC panel formed so that the lower surface of the holder is exposed; thereby reducing the production cost while maintaining the rigidity and resisting lateral pressure and lifting load, thereby allowing the width of the double wall to be increased.
그러나 상기 배경기술은 패널간의 결합만을 위한 방법으로 더블월 접합부에 별도 보강이 필요하고 보강시 철근망 등의 일률적인 배치가 어려워 설치위치 오차 및 피복두께 오차가 발생하여 접합부의 성능저하 문제점이 있다.However, the above background technology is a method only for joining panels, so separate reinforcement is required at the double wall joint, and it is difficult to uniformly arrange reinforcing bars, etc. during reinforcement, which causes errors in installation location and cover thickness, resulting in problems with reduced performance at the joint.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 내외측 패널 합성 매개체 역할과 패널간 간격유지를 할 수 있도록 하고 철근 설치 위치 오차와 피복 두께 오차 발생 배제로 접합부 성능 확보가 가능하며 더블월 설치 후 접합부 내부를 보강하는 철근 배근 최소화로 현장작업이 간결화되며, 연속되게 설치된 더블월 접합부 합성 효과 증대와 운반 및 가설 시 외부 충격에 저항하여 단면형상 유지하도록 하는 접합부 합성성능을 개선한 더블월, 이의 제작방법 및 이를 이용한 더블월 시공방법을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, and the purpose of the present invention is to provide a double wall, a method for manufacturing the same, and a double wall construction method using the same, which can secure joint performance by enabling the inner and outer panel composite mediator to act and the gap between the panels to be maintained, and by eliminating the occurrence of errors in the reinforcing bar installation position and the errors in the cover thickness, and by minimizing the reinforcement bar arrangement for reinforcing the inside of the joint after the double wall installation, and by improving the joint composite performance by increasing the composite effect of the continuously installed double wall joint and resisting external impact during transportation and construction to maintain the cross-sectional shape.

본 발명의 더블월(1)은 도 1에 도시된 바와 같이, 외측 패널(110) 및 내측 패널(120)이 이격되어 위치하고, 외측 패널(110)과 내측 패널(120)을 더블월 합성부재(20)로 연결하도록 하여, 외측 패널(110) 및 내측 패널(120)은 판 형상의 프리캐스트 콘크리트로 이루어지며 평행하게 일정거리 이격되어 구성되도록 한다. As shown in Fig. 1, the double wall (1) of the present invention has an outer panel (110) and an inner panel (120) spaced apart from each other, and connects the outer panel (110) and the inner panel (120) with a double wall composite member (20). The outer panel (110) and the inner panel (120) are made of plate-shaped precast concrete and are configured to be spaced apart from each other in parallel at a certain distance.
이와 같이, 외측 패널(110)과 내측 패널(120)의 내부에 더블월 합성부재(20)를 설치하여, 외측 패널(110)과 내측 패널(120)의 합성 매개체 역할과 외측 패널(110)과 내측 패널(120)간의 간격유지 역할을 하도록 하며, 연속되게 설치된 더블월(1) 접합부 합성 효과를 증대시키고, 더블월(1)의 운반 및 가설 시 외부 충격에 저항하여 단면형상 유지하도록 할 수 있다.In this way, by installing the double wall composite member (20) inside the outer panel (110) and the inner panel (120), it acts as a composite medium between the outer panel (110) and the inner panel (120) and maintains a gap between the outer panel (110) and the inner panel (120), increases the composite effect of the joint of the double wall (1) installed continuously, and can maintain the cross-sectional shape by resisting external impact during transportation and installation of the double wall (1).
본 발명에서는 특히, 외측 패널(110) 및 내측 패널(120)의 폭방향 양측의 하단부에 각각 블록아웃된 절취부(111)(121)가 형성되도록 하여, 더블월(1)의 연속시공시 도 2에서와 같이 절취부(111)(121)을 통하여 수평보강철근 배근을 용이하도록 하여 더블월 접합부의 단면 성능을 향상시킬 수 있다.In the present invention, in particular, by forming cut-out portions (111)(121) that are blocked out at the lower ends of both sides in the width direction of the outer panel (110) and the inner panel (120), horizontal reinforcing bars can be easily arranged through the cut-out portions (111)(121) during continuous construction of the double wall (1), as shown in Fig. 2, thereby improving the cross-sectional performance of the double wall joint.
특히, 도 1에서와 같이, 외측 패널(110) 및 내측 패널(120)의 절취부(111)(121)는 부재력이 크게 발생하여 유효단면 확보 필요 구간에 형성시켜 부재력이 크게 발생하는 구간 유효단면 확보(절취부가 없는 단면의 두께; d1, 절취부가 형성되어 있는 부분의 단면 두께; d2)로 접합부 단면성능 증대시킬 수 있다. In particular, as shown in Fig. 1, the cut-outs (111)(121) of the outer panel (110) and the inner panel (120) are formed in sections where a large amount of member force is generated and securing an effective cross-section is necessary, thereby increasing the cross-sectional performance of the joint by securing an effective cross-section in a section where a large amount of member force is generated (the thickness of the cross-section without the cut-out; d1, the cross-sectional thickness of the section where the cut-out is formed; d2).
본 발명에서 더블월 합성부재(20)는 철근 설치 위치 오차와 피복 두께 오차 발생 배제로 접합부 성능 확보가 가능하며, 더블월(1) 설치 후 접합부 내부를 보강하는 철근 배근 최소화로 현장작업 간결화 역할을 한다.In the present invention, the double wall composite member (20) can secure joint performance by eliminating errors in reinforcing bar installation location and covering thickness, and simplifies on-site work by minimizing reinforcement bar placement to reinforce the inside of the joint after installation of the double wall (1).
이와 같은 더블월 합성부재(20)는 도 3에서와 같이, 상단 폐합철물(210), 하단 폐합철물(220) 및 상단 폐합철물(210)과 하단 폐합철물(220)의 사이에 위치하는 중앙 폐합철물(230)과, 상단 폐합철물(210), 하단 폐합철물(220) 및 중앙 폐합철물(230)을 수직으로 연결하는 접합부보강철근(240)으로 이루어진다.As shown in Fig. 3, a double-wall composite member (20) of this type is composed of an upper closure member (210), a lower closure member (220), a central closure member (230) positioned between the upper closure member (210) and the lower closure member (220), and a joint reinforcing bar (240) that vertically connects the upper closure member (210), the lower closure member (220), and the central closure member (230).
상단 폐합철물(210), 하단 폐합철물(220) 및 중앙 폐합철물(230)은 각각 수직 판 형상의 접합판(211)(221)(231)과 접합판(211)(221)(231)의 폭방향 양측면에서 외측 직각방향으로 연장되는 돌출판(212)(222)(232)으로 구성된 ㄷ자 형상으로 더블월 내외측 패널에 설치되어 운반 및 가설시 외부 충벽에 저항하여 더블월 단면형상 유지하도록 하며, 돌출판을 이용하여 내외측 패널 합성 매개체 역할을 하도록 한다.The upper closure member (210), lower closure member (220) and central closure member (230) are each configured in a ㄷ shape by a vertical plate-shaped joining plate (211)(221)(231) and a protruding plate (212)(222)(232) extending in an outer right-angled direction from both sides of the width direction of the joining plate (211)(221)(231), and are installed on the inner and outer panels of the double wall to resist external impact during transportation and installation, thereby maintaining the double wall cross-sectional shape, and using the protruding plate to act as a composite medium for the inner and outer panels.
외측 패널(110) 및 내측 패널(120)의 높이에 대응하여 상단부와 하단부에 각각 위치하도록 상단 폐합철물(210)에서 하부로 일정거리 이격되어 하단 폐합철물(220)이 구성되는데, 중앙 폐합철물(230)은 상단 폐합철물(210)과 하단 폐합철물(220)의 사이에 1개 이상이 구성될 수 있다.The lower closure member (220) is configured to be spaced a certain distance downward from the upper closure member (210) so as to be positioned at the upper and lower portions corresponding to the heights of the outer panel (110) and the inner panel (120), and one or more central closure members (230) may be configured between the upper closure member (210) and the lower closure member (220).
이와 같이 상단 폐합철물(210), 하단 폐합철물(220) 및 중앙 폐합철물(230)은 수직으로 연결하도록 접합부보강철근(240)이 구성되는데, 접합부보강철근(240)은 접합판(211)(221)(231)의 내측면 또는 외측면에 용접 등의 공지의 다양한 방식으로 접합되도록 하여 접합부의 성능을 확보하도록 할 수 있다.In this way, the upper closure member (210), the lower closure member (220), and the central closure member (230) are configured to be vertically connected by a joint reinforcing bar (240). The joint reinforcing bar (240) can be joined to the inner or outer surface of the joint plate (211), (221), (231) by various known methods such as welding, so as to secure the performance of the joint.
이와 같이 구성되는 더블월 합성부재(20)는 상단 폐합철물(210), 하단 폐합철물(220) 및 중앙 폐합철물(230)의 돌출판(212)(222)(232)이 각각 외측 패널(110) 및 내측 패널(120)의 내측면에 접하고 하단 폐합철물(220)의 돌출판(222)이 외측 패널(110) 및 내측 패널(120)의 절취부(111)(121)에 노출되도록 각각 외측 패널(110) 및 내측 패널(120)의 양측 단부에 위치하여 합성된다.The double-wall composite member (20) configured in this manner is composited so that the protruding plates (212)(222)(232) of the upper closure member (210), the lower closure member (220) and the central closure member (230) are in contact with the inner surfaces of the outer panel (110) and the inner panel (120), respectively, and the protruding plate (222) of the lower closure member (220) is exposed to the cut portions (111)(121) of the outer panel (110) and the inner panel (120), respectively, at both ends of the outer panel (110) and the inner panel (120).
특히, 본 발명에서는 도 1 내지 도 3에서와 같이, 중앙 폐합철물(230)은 접합판(231)의 내측면에서 내측 수평방향으로 돌출하도록 내부합성철근(234)이 구성되도록 하여 내측 패널(120)과 외측 패널(110)의 사이에 타설되는 콘크리트와의 합성이 용이하도록 한다.In particular, in the present invention, as shown in FIGS. 1 to 3, the central closure member (230) is configured such that the internal composite reinforcing bar (234) protrudes in an inner horizontal direction from the inner surface of the joint plate (231), thereby facilitating composite with the concrete poured between the inner panel (120) and the outer panel (110).
또한, 중앙 폐합철물(230)은 접합판(231)의 외측면에서 외측 수평방향으로 돌출하도록 간격유지철근(235)이 구성되도록 할 수 있는데, 이 간격유지철근(235)은 외측 단부가 고리형으로 이루어질 수 있으며 더블월(1) 연속시공시 접합부 보강을 위한 수직보강철근(320) 시공시 수직보강철근(320) 간격을 유지하도록 하며 수직보강철근(320)이 간격유지철근(235)와 결합하여 더블월 접합부 단면 성능을 향상시킬 수 있다.In addition, the central closing member (230) may be configured such that the spacing-maintaining reinforcing bar (235) protrudes in the outer horizontal direction from the outer surface of the joint plate (231). The spacing-maintaining reinforcing bar (235) may have an outer end formed in a ring shape, and when constructing the vertical reinforcing bar (320) for reinforcing the joint during continuous construction of the double wall (1), the spacing of the vertical reinforcing bar (320) is maintained, and the vertical reinforcing bar (320) may be combined with the spacing-maintaining reinforcing bar (235) to improve the cross-sectional performance of the double wall joint.
또한, 부재력 최대 발생 구간인 합성부재 상단 및 하단의 상단 폐합철물(210) 및 하단 폐합철물(220)의 접합판(211)(221)은 각각 관통하여 수평 연결공(216)(226)이 양측에 대칭으로 형성되도록 하여, 도 4 및 도 6에서와 같이, 수평보강철근(310)을 더블월(1) 간 접합부의 인접한 상단 폐합철물(210) 및 하단 폐합철물(220)을 관통하여 배근되도록 하여 접합부 단면성능을 향상시키도록 할 수 있다.In addition, the joint plates (211)(221) of the upper and lower closure members (210) and the lower closure members (220) at the upper and lower ends of the composite member, which are the sections where the maximum absence force occurs, are respectively penetrated to form horizontal connecting holes (216)(226) symmetrically on both sides, so that the horizontal reinforcing bars (310) are arranged to penetrate the adjacent upper closure members (210) and lower closure members (220) of the joint between the double walls (1), thereby improving the cross-sectional performance of the joint.
특히, 본 발명에서는 하단 폐합철물(220)의 돌출판(222)은 절취부(111)(121)로 노출되게 되는데, 하단 폐합철물(220)의 돌출판(222)에 관통하여 결합공(227)이 형성되도록 하여, 더블월(1)의 연속시공시에 도 4 및 도 6에서와 같이, ㄷ 자 형상의 수평연결철근(330)의 양단부를 인접한 하단 폐합철물(220)의 돌출판(222) 결합공(227)에 각각 삽입되어 구성하도록 하여 더블월(1)간 연결을 하면서도 부재력이 크게 발생하는 구간 유효단면을 보강하도록 하는 것이다.In particular, in the present invention, the protruding plate (222) of the lower closing member (220) is exposed by the cut portion (111)(121), and a joining hole (227) is formed by penetrating the protruding plate (222) of the lower closing member (220), so that when continuously constructing the double wall (1), as shown in FIGS. 4 and 6, both ends of the horizontal connecting reinforcing bar (330) in the shape of the letter “ㄷ” are inserted into the joining hole (227) of the protruding plate (222) of the adjacent lower closing member (220), thereby reinforcing the effective cross-section of the section where the member force is greatly generated while connecting the double walls (1).

이때, 도 3에서와 같이, 접합부보강철근(240), 내부합성철근(234) 및 간격유지철근(235) 등 더블월 합성부재(20)가 완전히 제작된 이후에 외측패널(110) 및 내측 패널(120)에 차례로 합성시키도록 할 수도 있고, 도 7a에서와 같이, 더블월 합성부재(20)의 상단 폐합철물(210), 중앙 폐합철물(230) 및 하단 폐합철물(220) 만을 위치시키고 외측 패널(110)에 합성시킨 후에 접합부보강철근(240), 내부합성철근(234) 및 간격유지철근(235) 등을 단계적으로 구성하여 완성하도록 할 수도 있다.At this time, as in FIG. 3, after the double wall composite member (20), such as the joint reinforcing bar (240), the internal composite reinforcing bar (234), and the spacing-maintaining reinforcing bar (235), are completely manufactured, they may be sequentially manufactured on the outer panel (110) and the inner panel (120), or, as in FIG. 7a, only the upper closure member (210), the central closure member (230), and the lower closure member (220) of the double wall composite member (20) may be positioned and manufactured on the outer panel (110), and then the joint reinforcing bar (240), the internal composite reinforcing bar (234), and the spacing-maintaining reinforcing bar (235) may be gradually constructed to complete the manufacturing process.
