Description

데크 단부에서 긴장 정착시킨 장스팬 내화 데크의 긴장재 정착시스템 및 그 시공방법Tension material fixing system of long span fireproof deck fixed in deck end and its construction method
본 발명은 장스팬 내화 데크의 긴장재 정착시스템에 관한 것으로, 특히 데크 단부에서 데크플레이트의 파손이나 훼손없이 상향으로 굽힘변위량을 부여하여 장스팬에서의 처짐을 방지할 수 있고, 긴장재의 정착 지점에서의 배치 방향이 긴장력 방향과 일치시킬 수 있도록 한 데크 단부에서 긴장 정착시킨 장스팬 내화 데크의 긴장재 정착시스템 및 그 시공 방법에 관한 것이다.The present invention relates to a tension member fixing system of a long span fireproof deck, in particular, it is possible to prevent the deflection in the long span by imparting a bending displacement upward without damage or damage to the deck plate at the deck end, It relates to a tension member fixing system of a long span fireproof deck that is tension-fixed at one end of a deck so that the direction of the arrangement coincides with the direction of the tension force, and a construction method thereof.
H형강 보의 상부플랜지 위에 슬래브를 타설하고, 슬래브와 H형강 보는 보 상부플랜지 위에 설치된 전단 연결재(쉬어 스터드)에 의해 일체화하는 철골 합성보 시스템이 알려져 있다. 이 경우, H형강 보위에 슬래브가 걸쳐지기 때문에 보를 포함한 바닥시스템 전체의 높이가 철근콘크리트 구조에 비해 매우 높아지게 되는 문제점이 있다.A steel composite beam system is known in which a slab is placed on an upper flange of an H-beam, and the slab and an H-beam are integrated by a shear connecting member (shear stud) installed on the upper flange of the beam. In this case, since the slab is spread over the H-beams, there is a problem that the height of the entire floor system including the beams becomes very high compared to the reinforced concrete structure.
이를 해결하기 위한 대안으로 건축물의 제한된 높이 이내에서 최대한의 용적율을 끌어 낼 수 있는 슬림 플로어(Slim Floor) 공법이 개발되어 있다. 이 슬림 플로어 공법은 슬래브를 철골보 내에 삽입하여 시공하는 합성바닥판 공법의 총칭이다. 철골보는 하부 플팬지의 폭이 상부 플랜지의 폭에 비해 큰 비대칭 H형강 보를 사용하여 보의 단면효율을 높이고, 보의 춤을 기존의 것 보다 작게 할 수 있어 바닥판 전체의 높이를 기존의 합성보에 비해 크게 절감할 수 있다. 또한, 철골보의 웨브에 슬래브를 삽입하기 때문에 상대적으로 층고를 줄일 수 있고 바닥판과 보의 일체성 향상, 내화피복 불필요, 층고 절감으로 인한 외장재의 절감 등 많은 장점이 있는 공법이다.As an alternative to solve this problem, a slim floor method has been developed that can draw the maximum volume ratio within the limited height of the building. This slim floor method is a general term for the composite floor plate method in which a slab is inserted into a steel ball. Steel beams use asymmetric H-beams whose width is lower than that of upper flanges to increase the cross-section efficiency of the beams and make the beams dance smaller than conventional ones. Compared with this, it can save a lot. In addition, since the slab is inserted into the web of the cheolgolbo can relatively reduce the floor height and improve the integrity of the bottom plate and the beam, there is no need for fireproof coating, it is a method that has a number of advantages such as the reduction of the exterior material due to the floor height reduction.
그런데 슬래브에 적용되는 데크플레이트의 시공시 작업자 또는 자재 중량물이 데크플레이트상에 작용하는 경우 데크플레이트는 처짐량이 커져 장스팬의 구현을 어렵게 한다. 또한 처짐을 방지하기 위한 동바리를 별도로 설치해야 하고, 작은 보를 중간에 설치해야 함으로 경제성과 시공성을 저하시키게 된다.However, when the construction of the deck plate applied to the slab when the worker or material weight acts on the deck plate, the deck plate is difficult to implement the long span because the amount of deflection. In addition, to prevent sag, a separate copper bar must be installed, and a small beam must be installed in the middle, thereby degrading economic efficiency and constructability.

At this time, the two tension points for the support (20a) is located symmetrically with respect to the center of the concrete filling bone 12 is installed in the central section. This is for the tension member 40 to exert an upward bearing force at two places per one concrete filling bone 12.
긴장재 지점용 서포트(20a)는 도 5 및 도 6과 같이 하부에 긴장재(40)가 끼워지는 복수의 긴장재 끼움홈(201a)을 갖는 수직판(201)과, 수직판(201)의 상단에 위치하여 데크플레이트 본체(10)의 상면에 접합되는 상부 접합판(202)과, 수직판(201)의 양측면에 위치하여 콘크리트 채움골(12)의 벽면에 접합되는 측면 접합판(203) 및 수직판(201)의 하단에 위치하여 콘크리트 채움골(12)의 바닥면에 접합되는 하부 접합판(204)을 구비하고 있다.The tension point support 20a is located at the top of the vertical plate 201 and the vertical plate 201 having a plurality of tension member fitting grooves 201a into which the tension material 40 is fitted, as shown in FIGS. 5 and 6.

데크플레이트 본체(10)의 양단부측 측면 모서리에는 마구리 보강 앵글(50)이 각기 용접으로 접합되어 있다. 마구리 보강 앵글(50)은 강재로 제작된 것으로 길이방향으로 ㄱ자 단면 구조를 갖는다. 마구리 보강 앵글(50)은 긴장재(40)에 긴장력이 발휘되는 경우 데크플레이트 본체(10)의 마구리판(11)의 모서리부를 보강하여 그 변형을 방지한다.The copper reinforcement angles 50 are respectively joined by welding to the both end side side edges of the deck plate main body 10. As shown in FIG. The copper reinforcement angle 50 is made of steel and has a L-shaped cross-sectional structure in the longitudinal direction. When the tension reinforcement angle 50 is exerted a tension force on the tension member 40 reinforces the corner portion of the flange plate 11 of the deck plate body 10 to prevent its deformation.
마구리 보강 앵글(50)에 긴장재 정착구(160)가 접하여 설치되어 있다. 긴장재 정착구(160)는 데크플레이트 본체(10)의 배치 방향과 직각방향으로 놓여져 마구리 보강 앵글(50)에 접합되어 설치된다.The tension fixing member 160 is provided in contact with the copper reinforcement angle 50. The tension member fixing unit 160 is placed in a direction perpendicular to the arrangement direction of the deck plate body 10 and is attached to the copper reinforcement angle 50.
긴장재 정착구(160)는 길이 방향으로 ㄱ자 단면 구조를 갖는 경우 도 7과 같이 상면에 일정 간격마다 콘크리트 충전용 홀(161)이 더 형성되어 구성될 수 있다. 콘크리트 충전용 홀(161)은 장스팬 내화 데크의 시공시 타설되는 콘크리트가 긴장재 정착구(160)와 마구리판(11)의 사이에 형성되는 공간으로 용이하게 충전이 이루어지도록 하기 위한 것이다. 한편, 긴장재 정착구(160)는 양단에 보강 날개(162)가 더 접합되어 구성될 수 있다.When the tension fixing unit 160 has a L-shaped cross-section in the longitudinal direction, a concrete filling hole 161 may be further formed on the upper surface at regular intervals as shown in FIG. 7. The concrete filling hole 161 is to facilitate filling into a space formed between the tension fixing unit 160 and the copper plate 11 when the concrete poured during the construction of the long span fireproof deck. On the other hand, the tension fixing unit 160 may be configured by further joining the reinforcement blades 162 at both ends.
한편, 장스팬 내화 데크의 긴장재 정착시스템에서는 긴장재(40)의 양단을 긴장재 정착구(160)를 삽통시켜 2개소에 설치된 긴장재 지점용 서포트(20a,20a)의 각기 긴장재 끼움홈(201a,201a)에 끼운 후 긴장재(40)를 단부에서 도 3과 같이 조임너트(70)의 나사 결합을 이용하거나, 도 8과 같이 웨지(34)와 웨지 하우징(33)의 결합을 통해 긴장재 정착구(160)측에 정착시킬 수 있다.On the other hand, in the tension fixing system of the long-span fire-resistant deck, both ends of the tension member 40 are inserted into the tension member fitting grooves 20a, 20a of the tension member points support 20a, 20a installed at two places by inserting the tension member fixing holes 160, respectively. After inserting the tension member 40 at the end by using the screw coupling of the tightening nut 70 as shown in FIG. 3, or through the coupling of the wedge 34 and the wedge housing 33 as shown in FIG.

이와 같이 구성된 데크 단부에서 긴장 정착시킨 장스팬 내화 데크플레이트의 긴장재 정착시스템을 적용한 장스팬 내화 데크플레이트의 시공 방법의 일 예를 설명한다.An example of the construction method of the long span fireproof deck plate to which the tension material fixing system of the long span fireproof deck plate tension-fixed at the deck end comprised in this way is demonstrated.
데크플레이트 본체 설치Deck Plate Body Installation
먼저, 철골 기둥(도시안됨)에 도 9의 (가)와 같이 서로 대향된 H형강 보(5)가 설치된 상태에서, 도 9의 (나)와 같이 데크플레이트 본체(10)의 양 단부가 H형강 보(5)에 지지되게 배치된다. 이때 데크플레이트 본체(10)의 양 단부는 H형강 보(5)의 하부 플랜지의 상면에 올려져 걸침 지지되도록 한다. 이후 데크플레이트 본체(10)는 볼트 또는 용접을 통해 H형강 보(5)에 고정된다.First, in the state where the H-beams 5 opposed to each other are installed on the steel column (not shown) as shown in FIG. 9A, both ends of the deck plate body 10 as shown in FIG. It is arranged to be supported by the section steel beam (5). At this time, both ends of the deck plate body 10 is raised on the upper surface of the lower flange of the H-beams 5 to be supported. The deck plate body 10 is then fixed to the H-beams 5 through bolts or welding.
이때 데크플레이트 본체(10)는 양 단부에 콘크리트 타설에 대비하기 위해 마구리판(11)이 설치된 것이 적용된다.At this time, the deck plate body 10 is applied to the installation of the copper plate 11 in order to prepare for concrete pouring at both ends.
긴장재 및 긴장재 지점용 서포트 배치Support placement for tension and tension point
그 다음, 긴장재(40)의 배치 및 긴장재 지점용 서포트(20a)의 설치가 이루어진다.Then, arrangement of the tension member 40 and installation of the tension point support 20a are made.
즉, 각 콘크리트 채움골(12)마다 긴장재(40)를 2개씩 도 2 내지 4와 같이 데크플레이트 본체(10)의 콘크리트 채움골(12)에 늘어지게 배치한 후, 긴장재(40)의 위로 콘크리트 채움골(12)마다 2개소에 긴장재 지점용 서포트(20a)를 고정 설치한다.That is, two tension members 40 are disposed at each of the concrete filling bones 12 so as to hang on the concrete filling bones 12 of the deck plate body 10 as shown in FIGS. 2 to 4, and then the concrete is placed on the tension material 40. Fixing point (20a) for the tension material point is fixed to two places every filling bone (12).
긴장재 정착유닛 설치Installation of tension member fixing unit
그 다음, 도 4와 같이 데크플레이트 본체(10)의 길이 방향 양단부측에 각기 긴장재 정착구(160)를 접합시켜 놓는다.Next, as shown in FIG. 4, the tension member fixing members 160 are bonded to both ends of the deck plate main body 10 in the longitudinal direction.
이때 긴장재(40)는 양단이 긴장재 정착구(160)를 삽통하여 외부로 노출되도록 한다.At this time, both ends of the tension member 40 are exposed to the outside by inserting the tension member anchorage 160.
긴장재 긴장 정착Tension tension settlement
그 다음, 긴장재(40)의 양단부에 도 3과 같이 조임너트(70)를 나사 결합시킨다. 이때 조임너트(70)는 긴장재 정착구(160)에 지지된 상태로 회전 조임한다. 따라서 긴장재(40)가 긴장재 지점용 서포트(20a)에 접촉하여 상승지지력이 발휘된다.Next, the tightening nut 70 is screwed to both ends of the tension member 40 as shown in FIG. 3. At this time, the tightening nut 70 is rotationally tightened while being supported by the tension fixing unit 160. Therefore, the tension member 40 comes into contact with the tension point support 20a to exert an upward bearing force.
물론 이 단계에서 긴장재(40)의 양단을 도 8과 같이 웨지(34)와 웨지 하우징(33)의 결합을 통해 긴장시킬 수도 있다. 즉, 유압잭(도시안됨)을 사용하여 긴장재(40)를 긴장시킨 후 웨지(34)를 웨지 하우징(33)에 고정 정착시켜서 이루어질 수도 있다.Of course, at this stage, both ends of the tension member 40 may be tensioned through the coupling of the wedge 34 and the wedge housing 33 as shown in FIG. 8. That is, it may be made by fixing the wedge 34 to the wedge housing 33 after tensioning the tension member 40 using a hydraulic jack (not shown).
이에 의해 데크플레이트 본체(10)는 양단에서 일정한 캠버각이 형성되고 중앙에서 상향으로 솟아오른 일정량의 변위량을 갖게 된다. 이때 변위량은 데크플레이트 본체(10)의 길이(ℓ)에 대해 ℓ/200~ℓ/250 만큼 가질 수 있다.As a result, the deck plate body 10 has a predetermined camber angle at both ends and has a certain amount of displacement rising from the center upward. At this time, the displacement amount may have as much as ℓ / 200 ~ ℓ / 250 with respect to the length ℓ of the deck plate body (10).
이로 인해 슬래브 시공 완료 후 데크플레이트 본체(10)가 받게 될 하중은 긴장재 지점용 서포트(20a)를 통해 긴장재(40)에 전달되고, 긴장재(40)에 전달된 힘은 보(5)에 전달되어 처짐이 방지되는 메카니즘을 갖게 된다.Due to this, the load that the deck plate body 10 will receive after completion of the slab construction is transmitted to the tension member 40 through the tension point support 20a, and the force transmitted to the tension member 40 is transmitted to the beam 5. There is a mechanism to prevent sag.
콘크리트 슬래브 시공Concrete Slab Construction
그 다음, 데크플레이트 본체(10)의 상면에 도 9의 (다)와 같이 콘크리트(200)를 타설한다. 이때 콘크리트의 타설된 상면의 높이는 데크플레이트 본체(10) 상면의 높이보다 높게 이루어진다. 따라서 타설 콘크리트는 긴장재(40) 및 긴장재 정착유닛(30)을 내설하여 양생되어져 콘크리트 슬래브를 이루게 된다.Next, the concrete 200 is poured on the upper surface of the deck plate body 10 as shown in FIG. At this time, the height of the upper surface of the concrete is made higher than the height of the upper surface of the deck plate body (10). Therefore, the pour concrete is cured by installing the tension member 40 and the tension member fixing unit 30 to form a concrete slab.
이와 같이 콘크리트가 타설되어 작용되는 슬래브의 하중은 미리 인가되어진 긴장재(40)의 긴장력으로 인한 긴장재 서포트(20a)의 상향력 발생으로 데크플레이트 본체(10)가 처짐되는 현상은 발생되지 않는다.As such, the load of the slab acting by placing concrete does not cause the deck plate body 10 to sag due to the upward force generated by the tension support 20a due to the tension of the tension material 40 applied in advance.
또한, 긴장재 지점용 서포트(20a)에 의해 데크플레이트의 파손이나 훼손없이 상향으로 굽힘변위량을 인가시킬 수 있고, 마구리 보강 앵글(50)에 의해 데크플레이트 본체(10)의 단부의 변형을 방지할 수 있다.In addition, it is possible to apply the bending displacement amount upward without breakage or damage of the deck plate by the tension point support (20a), it is possible to prevent the deformation of the end of the deck plate body 10 by the copper reinforcement angle (50). have.

본 발명의 데크 단부에서 긴장 정착시킨 장스팬 내화 데크의 긴장재 정착시스템은 긴장재 정착구를 통해 긴장재의 긴장 인가 방향과 긴장지점에서의 배치방향을 일치시킬 수 있어 긴장 효율이 좋아지며, 긴장재에 인가된 긴장력이 긴장재 지점용 서포트를 매개로 상향력을 발휘하고, 그 결과 데크플레이트 본체의 중앙 구간을 들어올려 상향 변위를 부여하게 되어 장스팬에서의 처짐을 방지할 수 있으며, 긴장재가 데크플레이트 본체에 직접 상향력을 부여하는 것이 아니라 긴장재 지점용 서포트를 매개로 함으로써 데크플레이트 본체가 찢기거나 파손되는 일 없이 시공이 가능하게 되는 매우 유용한 발명이다.The tension member fixing system of the long span fireproof deck having tension settled at the deck end of the present invention is able to match the direction of tension application of the tension member with the arrangement direction at the tension point through the tension member anchorage so that the tension efficiency is improved, and the tension force applied to the tension member. The tension force is exerted through the support for the point of tension member, and as a result, the center section of the deck plate body is lifted up to impart an upward displacement to prevent sagging in the long span, and the tension member is directly raised to the deck plate body. It is a very useful invention that can be installed without the force of the deck plate body torn or damaged by providing a support for the tension point point, rather than imparting force.
