Abstract

본 발명은 성형한 강판 거푸집에 콘크리트를 부어 넣은 성형 강판 콘크리트 보(a)에 관한 것이다. 성형 강판 콘크리트 보는 도 3과 같이 종래 기성제품 또는 성형 강재를 좌우 웨브 플레이트(13)와 상부플랜지(12)로 삼아 별도의 평판 하부플랜지에 접합한 U형 영구거푸집(1a, 1b)으로, 좌우 상부플랜지에는 데크플레이트(5)를 걸쳐서 콘크리트(15)를 채운 조립폐쇄단면 강콘크리트 보의 일종이다. 기존의 U형 영구거푸집은 적합한 규격의 기성 제품이 없고, 접합 개소가 많아 번거로우며 제작 시 제작비 부담이 크다. 그러므로 이에 대한 대안으로 상하 플랜지와 웨브를 코일로 연속성형 하거나, 강판으로 절곡 또는 프레스로 제작하는 방법을 적용한 것이다. 이 때 U형 영구거푸집은 단면 크기가 크면 제작 장비가 대형화 되므로 2 조각의 형 강판으로 분할제작 후 용접접합 하는 방안도 포함된다. 또한 형 강판을 이용한 영구 거푸집은 거푸집으로만 사용되는 것이 아니라 철근콘크리트 보의 철근과 같이 구조재로도 사용된다.The present invention relates to a molded steel sheet concrete beam (a) in which concrete is poured into a molded steel sheet formwork. As shown in FIG. 3, the molded steel plate concrete beam is a U-shaped permanent formwork (1a, 1b) bonded to a separate flat plate bottom flange by using a conventional ready-made product or a molded steel as the left and right web plate 13 and the upper flange 12, the upper left and right The flange is a kind of assembled closed cross-section steel concrete beam filled with concrete 15 over the deck plate (5). Existing U-shaped permanent formwork does not have ready-made products of suitable specifications, and it is cumbersome because there are many joining points, and the production cost burden is high when manufacturing. Therefore, as an alternative, the upper and lower flanges and the web may be continuously formed by coils, or bent or pressed into steel sheets. At this time, U-shaped permanent formwork has a large cross-sectional size, which makes the production equipment larger. It also includes a method of welding after split fabrication to form steel sheet. Also Permanent formwork using form steel is used not only as formwork but also as structural material like reinforcement of reinforced concrete beam.

성형 강판 콘크리트 보는 필요에 따라 하부플랜지(11) 근처 내부에 몇 개의 하단철근을 배근하거나 슬래브 내에 상단철근을 배근하여 중앙 정모멘트와 단부 부모멘트 저항 값을 증대시킬 수 있다. 형 강판(2) 하부플랜지 끝의 Y형 돌기(10)는 조립용접을 용이하게 하고 하부플랜지의 단면증대, 콘크리트와 부착내력을 증대시키므로 쉬어 코넥터(14)를 생략할 수 있다.Formed steel plate concrete beams may be increased by reinforcing some lower reinforcement inside the lower flange 11 or by reinforcing upper reinforcing bars in the slab as necessary, thereby increasing the value of the center static moment and the end parent moment. The Y-shaped projection 10 at the end of the lower flange of the sheet steel 2 facilitates assembly welding and increases the cross-sectional area of the lower flange, and increases the adhesion strength with the concrete, so that the sheer connector 14 may be omitted.

쉬어 코넥터는 스터드나, 철근, 형강 등을 적용한다. 또한 좌우 상부플랜지(12) 사이에 용접(9) 부착한 ㄱ형강, ㄷ형강, 앵글 등은 슬래브와의 합성효과를 위한 쉬어 코넥터(14) 역할을 대신하며 현장 작업자의 통행용 발판으로 겸용한다. 성형 강판 콘크리트 보는 내화 성능도 우수하며 U형 브라켓(6)을 사용한 보 단부 접합은 종래의 접합 방법보다 우수하다.Shear connectors are made of studs, rebar and section steel. In addition, the a-beam, c-beam, angle, etc., which are welded 9 between the left and right upper flanges 12, replaces the role of the sheer connector 14 for the composite effect with the slab, and serves as a foothold for field workers. The molded steel plate concrete beam is also excellent in fire resistance performance, and the beam end joining using the U-shaped bracket 6 is superior to the conventional joining method.

Description

성형 강판 콘크리트 보 {Formed Steel Plate Concrete Beam}Formed Steel Plate Concrete Beam

종래 사용하던 조립폐쇄단면 강콘크리트 보는 도 3과 같이 기성제품이나 성형ㄱ형강(4) ㄷ형강 C형강 또는 Z형강을 좌우 웨브 플레이트(13)와 상부플랜지로 이용하며, 별도의 평판 하부플랜지(11)에 용접이나 볼트로 U형 영구거푸집(1a, 1b)을 조립 제작 후 상부플랜지(12)에 데크플레이트(5)를 얹고 콘크리트(15)를 채운 것이다. 그러나 다양한 크기의 U형 영구거푸집을 제작하기에 적합한 규격의 기성 제품이 없어 강판을 절단 제작하여야 하고, 접합개소가 많아 비용절감에 한계가 있다. 그러므로 이러한 문제점을 해결하기 위해 상하 플랜지와 웨브를 코일이나 강판으로 성형 제작하여 간략화 하는 것을 목적으로 한다.Conventionally used closed-section cross-section steel concrete beams are made of ready-made products or molded A-shaped steel (4) C-shaped steel or Z-shaped steel as left and right web plate 13 and the upper flange as shown in Figure 3, a separate flat lower flange (11) ) U-shaped permanent formwork (1a, 1b) by welding or bolt on the assembly after the deck plate (5) on the top flange 12 is filled with concrete (15). However, there is no ready-made product of the standard suitable for manufacturing the U-shaped permanent formwork of various sizes, and the steel sheet must be cut and manufactured, and there are limitations in cost reduction due to the large number of bonding points. Therefore, in order to solve this problem, it aims to simplify by forming the upper and lower flanges and the web by forming a coil or a steel sheet.

내화피복 공사 시 하부플랜지가 H형강처럼 웨브 플레이트 면에서 외곽으로 돌출되면 공사가 어려우므로 이를 개선하는 것도 주된 목적이 된다. 또한 제작 시 U형 거푸집 단면 크기가 크면, 제작 장비가 대형화 되므로 두 조각의 형 강판으로 분할제작 후 용접 접합한다.When the lower flange protrudes outward from the web plate surface like H-beams during the construction of fireproof coating, the main purpose is to improve the construction. Also, if the U-shaped formwork cross section size is large, the production equipment will be large. Weld and join after split fabrication.

종래의 조립폐쇄단면 강콘크리트 보는 이미 실험실에서 뿐만 아니라 실무현장 적용에서도 성공적인 효과를 얻고 있으나, ㄱ형강 ㄷ형강 C형강 또는 Z형강을 평판과 조립하여야 하므로 비효율적이다. 작은 규격의 U형 영구거푸집(1a, 1b)은 일정 폭의 코일을 연속 포밍으로 일시에 제작이 가능하나 크기가 작아 실구조물 적용은 다소 어렵다. 규격이 크면 광폭 코일의 구매가 어려우며 포밍 장비가 너무 커져 생산 능률이 떨어지고, 큰 규격의 U형 영구거푸집은 2개의 형 강판으로 분할 연속 포밍 하여 용접접합 하려면 용접변형이 발생하지 않도록 하는 간편한 방법이 필요하다. 또한 강판을 프레스로 눌러서 제작하면 보의 길이에 제한이 따른다.Conventional assembling closed section steel concrete beam has already been successful in the practical application as well as in the laboratory, but it is inefficient because the A-beam C-beam or Z-shaped steel must be assembled with the plate. Small size U-shaped permanent molds (1a, 1b) can be produced at a time by continuous forming a coil of a certain width, but the small size is difficult to apply the actual structure. If the size is large, it is difficult to purchase wide coils, the forming equipment is too large, and the production efficiency is reduced. In order to perform welding by dividing and continuous forming into a steel sheet, a simple method of preventing welding deformation is required. In addition, when the steel sheet is pressed by pressing, the length of the beam is limited.

U형 거푸집의 강판 두께가 전 단면을 통하여 균일하면 좌우 양 측면의 웨브가 하부플랜지에 비하여 차지하는 물량이 상대적으로 커져 비경제성을 보완하는 조치가 필요하다.If the steel plate thickness of the U-shaped formwork is uniform throughout the cross section, the volume of the web on the left and right sides is relatively larger than that of the lower flange, so that measures to compensate for the economic efficiency are necessary.

일반 철골보는 기둥이나 다른 큰 보와 접합할 때 웨브와 플랜지를 별도로 나누어 볼트 또는 용접 접합하는 것이 표준이지만 보다 간단하고 손쉬운 접합공법이 바람직하며 하부플랜지에 용착하는 쉬어 코넥터(14)를 생략하는 조치도 필요하다.In general, steel beams are standard for bolting or welding by dividing webs and flanges separately when joining columns or other large beams, but a simpler and easier joining method is preferable, and the action of omitting the sheer connector 14 to be welded to the lower flange is also required. need.

이러한 기존 기술의 여러 가지 문제점을 해결하는 방법으로 제안한 것이 성형강판 콘크리트 보이다.The proposed method to solve the various problems of the existing technology is a molded steel sheet concrete beam.

도 1에서 강판 U형 영구거푸집(1a, 1b) 양 상부플랜지(12)에 데크플레이트(5)를 걸치고 콘크리트를 부어 넣으면 U형 영구거푸집 좌우의 웨브 플레이트(13)는 일반 철근콘크리트 보의 스터럽이 되고, 하부플랜지(11)는 인장철근 역할을 한다. U형 양 상단의 상부플랜지를 인접한 성형강판 콘크리트 보의 상부플랜지와 연속시키면, 보 단부 상단이 인장내력을 발휘하여 부분강접(partial rigid)효과도 발휘한다. 또한 슬래브 내부의 상단철근(10a)은 배근량에 따라 부분강접(partial rigid)의 효과가 증가하는 효과를 볼 수 있다.In FIG. 1, when the deck plate 5 is placed on both upper flanges 12 of the steel U-shaped permanent dies 1a and 1b, and concrete is poured, the web plates 13 on the left and right of the U-shaped permanent dies have a stirrup of ordinary reinforced concrete beams. The lower flange 11 serves as a reinforcing bar. When the upper flanges of the U-shaped upper ends are continuous with the upper flanges of the adjacent formed steel plate concrete beams, the upper ends of the beams exert tensile strength and also exhibit a partial rigid effect. In addition, the upper reinforcement (10a) inside the slab can be seen the effect of increasing the effect of partial rigid (partial rigid) according to the reinforcement.

2개의 일반 형 강판 하부플랜지를 마주보고 용접하려면 평판인 하부플랜지의 용접부위를 개선하는 추가 비용과 용접 열로 인한 변형이 일어날 가능성이 있다. 또한 U형 영구거푸집(1a, 1b) 보를 기둥 또는 다른 큰 보에 접합하려면 하부플랜지(11) 하면에 돌출되는 용접 덧살을 평활하게 제거하는 수고를 해야 한다. 그러므로 일반 형강의 하부플랜지(11) 끝을 Y형 돌기로 말아 올린 형태의 형 강판을 코일로 연속 포밍하여 제작하면 Y형 돌기(10)의 성형곡률로 생성되는 곡면을 용접 덧살이 채워지는 공간으로 활용할 수 있다. 또한 2 개의 Y형 돌기는 하부플랜지의 단면을 증대시키는 역할을 하고 콘크리트와의 부착내력이 커지므로 쉬어 코넥터(14) 용착을 생략할 수 있다. 이 때 단일강판 U형 영구거푸집은 물론 쌍형 강판 U형 영구거푸집(1b)에도 필요하면 하부플랜지(11) 근처 내부에 몇 개의 하단철근(10b)을 배근하거나, 하부 보강 플레이트로 보강 할 수 있다.2 general To face and weld the bottom flange of the steel sheet, there is a possibility of deformation due to the additional cost and welding heat to improve the welded area of the flat bottom flange. In addition, in order to join the U-shaped permanent mold (1a, 1b) beam to the column or other large beams, it is necessary to effort to smoothly remove the welding gum protruding from the bottom of the lower flange (11). Therefore general The end of the lower flange (11) of the section steel rolled up with a Y-shaped protrusion When the steel sheet is continuously formed by forming a coil, the curved surface generated by the molding curvature of the Y-shaped protrusion 10 may be used as a space where the weld tooth is filled. In addition, the two Y-shaped protrusions serve to increase the cross-section of the lower flange and the adhesion strength with the concrete increases, so that the welding of the sheath connector 14 can be omitted. At this time, a single steel sheet U-shaped permanent formwork, as well as a pair If necessary also in the steel sheet U-shaped permanent formwork (1b) can be reinforced some lower reinforcing bars (10b) inside the lower flange 11, or reinforced with a lower reinforcement plate.

상부플랜지에는 바닥 슬래브와를 일체로 묶어서 합성효과를 발휘하는 쉬어 코넥터가 필요하다. 쉬어 코넥터(14)는 일반적으로 사용되는 스터드와 철근, 채널 등의 사용이 가능하다. 스터드의 용착작업에는 대용량의 전기가 필요하여 현장에서는 손 용접으로 대체 시공하는 경우가 많고, 이러한 손 용접 시공에 따라 부실시공 사례가 많다. 또한 현장 작업자의 통행에 장해요인이 되기도 하므로, ㄷ형강이나 ㄱ형강을 상부플랜지에 용접하여 사용하는 방법도 적용 가능하다. 이 때 ㄱ형강은 좌우 웨브 플레이트(13) 상호 간격을 유지시키는 폭지근 역할과 작업자 통행용 발판도 겸용한다.The upper flange requires a sheer connector that binds the bottom slab integrally and exerts a synthetic effect. Shear connector 14 can be used for the commonly used studs and rebars, channels and the like. The welding work of the studs requires a large amount of electricity, so the construction is often replaced by hand welding, and there are many cases of sub-construction according to the hand welding construction. In addition, because it may be a obstacle to the passage of field workers, it is also applicable to the method of welding the C-beam or a-beam to the upper flange. At this time, the a-beam acts as a width control for maintaining the gap between the left and right web plate 13, and also serves as a footrest for worker traffic.

H형강은 물론 조립폐쇄단면 강콘크리트 보에서도 하부플랜지가 웨브플레이트에서 돌출되면 내화피복 작업에 어려움이 있다. 또한 공사 후 탈락될 염려가 있으나 단일강판 또는 쌍형 강판 U형 영구거푸집(1b)은 직사각형이 되어 보의 표면에 돌출부가 없으므로 내화피복도 효과적이고, 강판 내에 비열이 큰 콘크리트(15)가 있으므로 H형강 등 일반 철골조 보다는 내화성이 큰 장점이 있다.If the lower flange protrudes from the web plate as well as the H-beam, the assembled closed section steel concrete beam has difficulty in fireproof coating. Also, there is a risk of dropping out after construction The U-shaped permanent formwork (1b) is rectangular, and there is no protrusion on the surface of the beam, so that the fireproof coating is effective, and the concrete (15) has a large specific heat in the steel plate, so the fire resistance is greater than that of general steel frames such as H-shaped steel.

종래 사용하던 조립폐쇄단면 강콘크리트 보의 U형 영구거푸집(1a, 1b)은 상부, 하부 웨브의 세 조각 단위 단면을 용접 또는 볼트로 조립 제작하여 왔다. 그러나 성형강판 콘크리트 보는 단일 강판이나 두 개의 강판을 연속 포밍 하거나 프레스 또는 절곡하여 제작하므로 제작비가 절감되고, 특히 쌍형 강판 U형 영구거푸집은 하부플랜지에 Y형 돌기(10)가 있어서 용접도 용이하고 용접변형도 적다. 또한 하부플랜지의 Y형 돌기는 하부플랜지(11) 단면증대 수단으로 활용될 뿐만 아니라 쉬어 코넥터(14) 대용으로도 적용이 가능하다.The U-shaped permanent formwork (1a, 1b) of the conventional closed closed cross-section steel concrete beam has been fabricated by welding or bolting the three-piece unit section of the upper and lower webs. However, molded steel sheet concrete beams are produced by continuously forming, pressing or bending a single steel sheet or two steel sheets, thereby reducing manufacturing costs. The U-shaped permanent formwork of the U-shaped steel sheet has a Y-shaped protrusion 10 on the lower flange, which facilitates welding and reduces welding deformation. In addition, the Y-shaped protrusion of the lower flange is not only utilized as a means for increasing the cross-sectional area of the lower flange 11, but also may be applied as a substitute for the sheer connector 14.

철골보는 기둥이나 다른 큰 보와의 접합 비용이 차지하는 비중이 큰데 U형 브라켓을 활용한 단부 접합은 구조상 효율 면에서도 우수하고 조립시간과 비용이 최소화되는 효과가 있다.Steel beams account for a large portion of the cost of joining columns or other large beams. The end joining using U-shaped brackets has excellent structural efficiency and minimizes assembly time and cost.

U형 영구거푸집(1a, 1b) 상부플랜지(12) 쉬어 코넥터는 스터드를 사용할 수 있고, 스터드 대신 ㄱ형강, ㄷ형강, 철근 등을 용접하면 슬래브와의 합성효과도 우수하며 현장 임시전기 사용 용량도 줄일 수 있다. 또한 작업자의 통행 발판으로도 활용이 가능하여 안전사고를 줄이는 효과도 기대할 수 있다.U-shaped permanent formwork (1a, 1b) The upper flange (12) Shear connector can use studs, and if the a-beams, t-beams, rebars, etc. are welded instead of the studs, the composite effect with the slab is excellent, and the capacity of the site temporary electricity is also used. Can be reduced. In addition, it can be used as a foothold for workers, so it can be expected to reduce safety accidents.
