Description

매립형철골띠장과 건축용영구보를 이용한 지하구조물 구축방법{Using reclamation steel perimeter beam and Girder which the basement infrastructure construction method}Using reclamation steel perimeter beam and girder which the basement infrastructure construction method}

본 발명은 매립형철골띠장(300)과 건축용영구보(120)를 이용한 지하구조물 구축방법에 관한 것으로, 더욱 상세하게는 지하터파기 공사 중 발생되는 횡력에 대하여 철골띠장과 건축용영구보(120)로 지지하여 굴토하며 지하 터파기 공사가 완료된 후에는 하부층부터 순차적으로 지하외벽(140)과 슬래브(130)를 시공하면서 상부층으로 골조공사를 함으로서, 굴토 중 슬래브(130)를 없애 지하터파기공사의 시공성을 극대화시키고, 지하외벽(140)을 순타시공하여 시공품질을 향상시킨 지하구조 물 구축방법에 관한 것이다.The present invention relates to a method for constructing an underground structure using a buried steel frame (300) and a building permanent beam (120), and more specifically, to a steel frame and a building permanent beam (120) with respect to the lateral force generated during the underground excavation construction. After the underground excavation work is completed, the structure of the underground excavation work is removed by removing the slab 130 from the excavation after constructing the basement outer wall 140 and the slab 130 sequentially from the lower floor. Maximizes, and relates to a method of building the underground structure to improve the construction quality by the net construction of the outer wall 140.

일반적으로 건물의 지하층을 시공하는 방법으로는 종래로부터 여러 가지의 시공법이 알려져 있으며 이를 분류하는 방식도 여러 가지가 있을 수 있지만, 이들을 지하구조물을 구축 시공하는 방향에 따라 분류하면 다음과 같이 크게 순타공법과 역타공법으로 대별할 수 있다.In general, as a method of constructing a basement of a building, various construction methods are known from the prior art, and there may be various methods of classifying them. However, if they are classified according to the direction of constructing and constructing underground structures, the following steps are performed. It can be divided into law and reverse punching method.

첫째로 상기 순타공법은 기존으로부터 가장 보편적으로 적용되고 있던 방식으로서, 이는 지상으로부터 흙막이벽(100)과 함께 버팀대, 레이커, 어스앵커, 락볼트 등과 같은 가설 지지수단을 설치하여 상기 흙막이벽(100)이 붕괴되지 않게 지지된 상태로 기초 저면 레벨까지 지하 토공사를 완료한 다음 상기 가설 지지수단을 아래에서부터 해체해 나가면서 최저층부터 지상까지 구조물을 순차적으로 시공하는 공법에 해당한다.First, the netting method is the most commonly applied method from the existing, which is installed from the ground along with the earth wall 100, the temporary wall support means such as braces, rakers, earth anchors, rock bolts, etc. This is a method of constructing the structure from the lowest floor to the ground while dismantling the temporary supporting means from the bottom, after completing the underground earthwork to the foundation bottom level in such a state that it is not collapsed.

둘째, 역타공법은 일명 탑다운(Top-Down) 공법이라고도 하는 것으로, 이는 지하 토공사를 수행해 나감과 동시에 지하층 본 구조물 공사를 병행함으로써 상기 시공된 지하층 구조물이 토공사 중에는 횡토압에 대한 버팀대의 역할을 하도록 하면서 지하 구조물을 위에서 아래 방향으로, 즉, 전술한 통상적인 순타공법과는 반대 방향으로 시공하여 내려가는 공법이다.Second, the reverse drilling method is also known as the top-down method, which performs underground earthworks and simultaneously performs the construction of the basement main structure so that the constructed underground structure acts as a support for the transverse pressure during earthwork. While the underground structure from the top to the bottom direction, that is, the construction method to go down in the opposite direction to the conventional netting method described above.

본 발명에서 제공하고자 하는 공법은 상기에서 설명한 방법들 중 역타공법에 있어서의 문제점을 개선하여 더욱 발전시킨 것으로, 특히 기존의 역타공법에서 나 타난 단점들을 최소화하면서 경제성과 시공성을 확보함과 동시에 지하외벽(140)의 시공에 있어서는 순타공법에 의해 연속 시공이 가능할 수 있도록 구현한 것이다.The method to be provided in the present invention has been further developed by improving the problems in the reverse punching method among the above-described methods, in particular, while ensuring the economy and constructability while minimizing the disadvantages of the conventional reverse punching method, the basement outer wall In the construction of (140), it is implemented so that continuous construction can be performed by the netting method.

이와 같은 본 발명과 관련하여 기존의 역타공법을 살펴 보면, 기존의 역타공법은 일반적으로 철근 콘크리트(또는 철골 철근콘크리트) 구조를 기본으로 하고 흙막이 벽체 공법으로는 슬러리 월을 적용하여 지하 영구 구조물과 슬러리 월을 일체화 시키면서 역타 시공하는 방식에 의해 이루어지고 있었다. 이와 같은 기존의 대부분의 역타공법은 철근 콘크리트조를 기본으로 하고 있기 때문에 습식 공사를 수행하기 위한 거푸집 공사 및 이 거푸집을 지지하기 위한 동바리 내지는 행거공사가 수반되어야만 하였다. 따라서 동바리를 설치할 경우에는 타설 콘크리트가 경화할 때까지 동바리 해체가 불가능함에 따라 하부 굴착 공정이 지연되는 단점이 있었으며, 이에 상기와 같은 단점을 보완하기 위한 방식으로서 거푸집을 상부에 기시공된 부재에 매다는 형식의 행거를 이용한 공법이 제안된 바 있다. 하지만, 상기 공법 또한 횡방향으로의 강성 부족과 진동에 대한 저항성 부족으로 콘크리트가 경화되기 이전에 행거의 변형 및 진동에 의한 소성상태 콘크리트에 균열이 발생하는 문제점을 갖고 있었다.Looking at the conventional reverse drilling method in relation to the present invention, the conventional reverse drilling method is generally based on reinforced concrete (or steel reinforced concrete) structure, and by using a slurry wall as a wall construction method, the underground permanent structure and slurry It was done by the method of reverse construction while unifying the wall. Since most of the existing reverse drilling methods are based on reinforced concrete tanks, a formwork for performing wet construction and a copper or hanger construction for supporting the formwork should be involved. Therefore, in the case of installing the copper barrier, it is impossible to dismantle the copper bar until the concrete is hardened, so that the lower excavation process is delayed. Therefore, as a way to compensate for the above-mentioned disadvantages, the formwork is hung on the upper structured member. A construction method using a hanger of the type has been proposed. However, the above method also had a problem that cracks occurred in the plastic state concrete by deformation and vibration of the hanger before the concrete was cured due to the lack of rigidity in the transverse direction and the lack of resistance to vibration.

한편, 상기와 같은 역타공법에 대한 또 다른 대안으로서 종래 임시 구조물로서의 흙막이벽(100) 지지용 버팀대를 설치하지 않고 건물의 영구 구조부재인 철골보를 흙막이 벽에 대한 스트러트로 활용하는 공법(이하 '영구부재 스트러트 공법'으로 약칭)이 제안된 바 있으며, 영구부재 스트러트 공법은 지하층의 기둥과 보부재를 하향 시공시에 설치하여 이 부재들이 재래식 흙막이 공법에서의 스트러트 역 할을 수행하도록 함으로써 가설 스트러트를 시공함에 따라 발생하는 터파기 공사의 시공성 저하, 가설 스트러트의 설치/해체 공정의 추가 등과 같은 단점을 보완할 수 있는 공법으로서 제안되었다.On the other hand, as another alternative to the reverse punching method as described above, a method of utilizing the cheolgolbo, which is a permanent structural member of the building as a strut for the retaining wall, without installing a brace for supporting the retaining wall 100 as a conventional temporary structure (hereinafter 'permanent') Permanent member strut method has been proposed, and the permanent member strut method installs the basement column and beam members during the downward construction so that these members perform the role of struts in the conventional earthquake construction method. It is proposed as a construction method that can compensate for the shortcomings such as deterioration of construction work of excavation work and additional installation / dismantlement of temporary struts.

지금까지의 역타공법의 경우 기본적으로 굴토중 발생되는 토압에 대해 영구부재인 보 뿐만 아니라 슬래브(130)도 일정부분 이상 지지하도록 설계되었다.Until now, the reverse drilling method is basically designed to support more than a portion of the slab 130 as well as the permanent member for the earth pressure generated during the excavation.

그러나, 상기와 같은 방식으로 이루어지는 기존의 역타공법의 경우 다음과 같은 단점을 안고 있었다.However, the conventional reverse punching method made in the above manner had the following disadvantages.

첫째, 슬래브(130)가 토압을 받는 구조로 설계되므로 굴토중에 슬래브(130)가 시공되어야 하며 콘크리트 타설 시 굴토공사와 간섭이 되거나 타설된 슬래브(130)가 벡호 등의 장비의 행동반경에 제약을 주어 시공성이 저하된다는 단점이 있었다.First, because the slab 130 is designed in a structure that is subjected to earth pressure, the slab 130 should be constructed during the excavation, and the slab 130 interferes with the excavation work when the concrete is placed or placed, and the slab 130 is restricted in the behavior radius of the equipment such as Beck. There was a disadvantage that the workability is reduced.

둘째, 기존의 역타공법은 외부 테두리에 철근 콘크리트 테두리보를 설치하는 경향이 대부분이며, 이 때 발생하는 외부 테두리보의 시공이 복잡할 뿐 아니라 시공시 가설재가 많이 소요되어 공사비 측면에서 비효율적인 면이 있었다.Second, the existing reverse drilling method tends to install reinforced concrete rim beams on the outer edges, and the construction of the external rim beams at this time is not only complicated, but also inconvenient in terms of construction costs due to the large amount of temporary construction materials. .

셋째, 테두리부에 철근 콘크리트 테두리보가 먼저 설치됨에 따라 지하 외벽은 연속 시공이 되지 못하고 분리 시공됨이 불가피하며, 이로 인하여 이음 철근의 선시공 작업 및 콘크리트 타설관의 매립공사, 철골보의 처짐을 방지하기 위한 행거 설치 공사 등과 같이 복잡한 공정이 추가되는 단점이 있는 것은 물론, 추후 지하외벽(140)의 콘크리트 타설에 있어 테두리보가 간섭됨으로써 타설 공사가 어려워지고 콘크리트 경화 후에는 조인트 부위에 누수 등 하자가 발생할 가능성이 높다는 문제 가 있었다.Third, as the reinforced concrete rim beam is first installed in the rim, it is inevitable that the underground outer wall cannot be continuously constructed and separated. Therefore, the construction of the joint reinforcement, the reclamation of the concrete placing pipe, and the sagging of the steel beam are prevented. Of course, there is a disadvantage in that a complicated process such as a hanger installation work is added, and in the future, when the concrete beams of the basement outer wall 140 are interfered with by the rim beam, the casting work becomes difficult, and after the concrete hardening, there is a possibility of defects such as leakage in the joint part. There was a problem that high.

본 발명은 상기한 종래의 역타공법의 문제들인 시공성과 경제성 및 품질에 관련한 문제들을 개선하고자 개발된 것으로서, 지하터파기 공사 중 발생되는 횡력에 대하여 철골띠장과 건축용영구보(120)로 지지하여 굴토하며 지하 터파기 공사가 완료된 후에는 하부층부터 순차적으로 지하외벽(140)과 슬래브(130)를 시공하면서 상부층으로 골조공사를 함으로서, 굴토 중 슬래브(130)를 없애 지하터파기공사의 시공성을 극대화시키고; , 지하외벽(140)을 순차적으로 시공함으로서 조인트를 없애 품질을 개선할 수 있는 지하구조물 구축방법을 제공하는데 기술적 과제가 있다.The present invention was developed to improve the problems related to the construction, economics and quality, which are the problems of the conventional reverse drilling method, and supported by steel frame and construction permanent column 120 for lateral force generated during underground excavation work. After the underground excavation work is completed, the construction of the underground excavation work is maximized by eliminating the slab 130 in the burrow by constructing the basement outer wall 140 and the slab 130 sequentially from the lower floor. There is a technical problem in providing an underground structure construction method which can improve the quality by removing the joint by sequentially constructing the basement outer wall 140.

상기한 기술적 과제를 해결하기 위해 본 발명은 건물의 지하부분 시공방법으로서, (a)통상의 방법으로 흙막이벽(100)을 시공하고 흙막이벽(100) 내부로 내부기둥(110)을 시공하는 단계; (b)흙막이벽(100) 내측 지반을 굴토하여 흙막이벽(100)에 철골좌대(210)를 설치하는 단계; (c)흙막이벽(100) 길이방향으로 매립형철골띠장(300)을 설치하는 단계; (d)건축물의 본 보부재가 설치되어야 할 위치에 건축용영구보(120)를 설치함과 동시에 매립형청골띠장과 결합하는 단계; (e)상기 (b)단계부터 (d)단계까지를 반복 시공하여 기초저면까지 터파기공사를 완료하는 단계; (f) 상기 흙막이벽(100) 내측으로 지하외벽(140)을 연속적으로 시공함과 동시에 건축용영구보상부로 슬래브(130)를 시공하는 단계;를 포함하여 이루어지는 것을 특징으로 하는 매립형철골띠장(300)과 건축용영구보(120)를 이용한 지하구조물 구축방법을 제공한다. In order to solve the above technical problem, the present invention provides a method of constructing a basement part of a building, the method comprising: (a) constructing a retaining wall 100 by a conventional method and constructing an inner pillar 110 into the retaining wall 100. ; (b) installing the steel frame 210 on the earth wall by excavating the inner ground of the earth wall 100; (c) installing the buried steel frame length 300 in the longitudinal direction of the earth wall (100); (d) installing the permanent column 120 for construction at the position where the main member of the building is to be installed and at the same time combining with the buried cheonggoljangjang; (e) repeating the steps (b) to (d) to complete the trench work to the foundation bottom; (f) constructing the slab 130 to the permanent permanent compensation for the construction and at the same time the construction of the basement outer wall 140 to the inside of the retaining wall (100); And provides a construction method for underground structures using the permanent forever (120).

본 발명에 따르면 다음과 같은 효과를 기대할 수 있다.According to the present invention, the following effects can be expected.

첫째, 건물의 지하부분을 시공함에 있어 슬래브(130) 없이 내부기둥(110)과 건축용 영구 보부재만 설치되므로 지하터파기공사와 골조공사의 간섭이 최소화되어 시공성이 극대화된다.First, in constructing the underground part of the building, only the inner pillar 110 and the permanent beam member for construction are installed without the slab 130, thereby minimizing the interference of the underground digging and framing work, thereby maximizing the constructability.

둘째, 지하터파기공사 중에는 매립형철골띠장(300)이 토압전달체로 역할을 하며, 지하외벽(140) 시공시에는 지하외벽(140)에 완전히 매립되므로 조인트발생이 최소화되어 시공성과 품질이 향상된다.Second, during underground excavation work, the buried steel frame 300 serves as a earth pressure carrier, and when the underground outer wall 140 construction is completely embedded in the underground outer wall 140, the joint occurrence is minimized to improve the construction and quality.

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 1은 본 발명에 따른 매립형철골띠장(300)과 건축용영구보(120)를 이용한 지하구조물 구축방법에 대한 시공순서를 보여주며, 도 2와 도 3은 본 발명에 따른 매립형철골띠장(300)을 이용하여, 지하외벽(140)의 연속시공이 가능한 지하구조물 구축방법에 바람직하게 이용할 수 있는 매립형철골띠장(300)의 실시예와 매립형철골띠장(300)과 건축용영구보(120)를 이용한 지하구조물 시공상세를 도시한다.Figure 1 shows the construction sequence for the construction method of the underground structure using the buried steel frame chapter 300 and the construction permanent bore 120 according to the present invention, Figure 2 and Figure 3 is a buried steel frame sheet 300 according to the present invention By using the embodiment of the buried steel belt long 300 and the buried steel belt long (300) and the construction permanent column 120 can be preferably used in the method of constructing the underground structure capable of continuous construction of the underground outer wall (140) The construction details are shown.

(a)단계 : 흙막이벽(100) 및 내부기둥(110) 시공 - 도 1(a)(a) step: construction of the earth wall (100) and the inner pillar (110)-Figure 1 (a)

건축선에 맞춰 흙막이벽(100)을 시공한다. 흙막이벽(100)은 H말뚝과 토류판, CIP, SCW, 시트파일 등 가설흙막이벽으로 시공 가능하다. Construct the earth wall 100 according to the construction line. Dirt wall (100) can be constructed as a temporary wall, such as H pile and earth plate, CIP, SCW, sheet pile.

흙막이벽(100)을 시공한 후에는 흙막이벽(100) 내부로 내부기둥(110)을 시공한다. 본 발명은 영구 지지공법을 적용하면서 실시하므로 본 단계에서 내부기둥(110)은 건물 지하부분의 구조체를 구성하는 영구 기둥이 된다.After constructing the retaining wall 100, the inner pillar 110 is constructed into the retaining wall 100. Since the present invention is carried out while applying a permanent support method, the inner pillar 110 at this stage becomes a permanent column constituting the structure of the basement of the building.

(b)단계 : 굴토 및 철골좌대(210) 설치 - 도 1(b)(b) step: installation of the oyster and steel frame 210-Figure 1 (b)

흙막이벽(100) 내측 지반을 굴토한다. 굴토깊이는 흙막이벽(100)의 안정적인 지지상태를 고려하면서 실시한다. It excavates the ground inside the retaining wall 100. The pit depth is carried out while considering the stable support state of the retaining wall (100).

흙막이벽(100)의 H-Pile이 드러나면 매립형철골띠장(300)을 설치하기 위한 철골좌대(210)를 설치한다. 철골좌대(210)는 이후의 공정에서 그 위에 설치될 매립형철골띠장(300)을 지지하고 지하터파기공사 시공 중에 발생되는 시공하중까지를 지지할 수 있도록 충분히 견고하게 설치한다.When the H-Pile of the retaining wall 100 is exposed, install the steel frame base 210 for installing the buried steel frame length 300. The steel frame base 210 is sufficiently firmly installed so as to support the buried steel frame length 300 to be installed thereon in a subsequent process and to support the construction load generated during the construction of the underground digging work.

(c)단계 : 매립형철골띠장 설치 - 도 1(c)(c) step: installation of a buried steel frame-Figure 1 (c)

흙막이벽(100) 길이방향으로 철골좌대(210) 위에 매립형철골띠장(300)을 설 치한다.Recessed wall 100 is installed on the steel frame base 210 in the longitudinal direction to install a buried steel frame (300).

이 때 매립형철골띠장(300)의 위치는 추 후 시공될 지하외벽(140) 폭의 중앙부에 위치시켜 지하외벽(140) 시공시에 매립될 수 있게 한다.At this time, the location of the buried steel frame 300 is located in the center of the width of the basement outer wall 140 to be constructed later to be buried at the time of construction of the basement outer wall 140.

매립형철골띠장(300)은 토압을 전달할 수 있고, 동시에 추 후 시공될 지하외벽(140)에 완전히 매립될 수 있는 규격으로 설계를 하여야 한다.The buried steel frame 300 is to be designed to the standard that can transmit the earth pressure, and at the same time completely buried in the basement outer wall 140 to be constructed later.

(d)단계 : 건축용영구보 설치 - 도 1(d)Step (d): Construction permanent construction-Fig. 1 (d)

건축계획에 맞는 위치에 건축용영구보(120)를 설치하고 매립형철골띠장(300)과 접합한다.Installed permanent construction beam 120 in a location that meets the building plan and bonded with a buried steel frame (300).

건축용영구보(120)는 건물의 바깥쪽으로는 매립형철골띠장(300)과 접합되며, 건물 내측으로는 내부 기둥 혹은 다른 위치의 건축용영구보(120)와 접합된다. The building permanent beam 120 is bonded to the buried steel frame length 300 outside the building, the interior of the building is bonded to the building permanent column 120 of the inner pillar or another location.
