Description

골형 웨브 강판 조립보{Built-up Beam having Profiled Steel Web}Corrugated web steel plate assembly beam {Built-up Beam having Profiled Steel Web}

본 발명은 조립보에 관한 것으로, 보다 상세하게는 웨브를 한 쌍의 골형강판으로 구성한 조립보에 관한 것이다. The present invention relates to an assembly beam, and more particularly to an assembly beam consisting of a web of a pair of corrugated steel sheet.

보란 구조적으로는 2지점에 의하여 수평 또는 그에 가까운 상태로 지지되어 재축에 대하여 직각 또는 빗방향의 하중을 받는 구조부재를 말한다. Structurally, structural means a structural member supported horizontally or near by two points and receiving a load perpendicular to the reaxial axis or in a comb direction.

철근콘크리트구조에 있어서 보는 현장타설공법에 의해 시공되므로 콘크리트가 응결, 경화하는 동안 일정한 형태와 치수를 유지시키기 위한 거푸집과 거푸집을 지지하기 위한 동바리가 필요하고 콘크리트가 충분한 강도에 도달할 때까지 이들을 존치시켜야 하는 단점이 있다. As it is constructed by the site casting method in reinforced concrete structure, it needs formwork to maintain the form and dimension during concrete condensation and hardening, and it is necessary to keep them until the concrete reaches sufficient strength. There is a drawback to this.

철골구조에서는 보통 H형강이 사용된다. 그러나 H형강으로 구성된 보에 있어서 웨브는 상대적으로 부재의 단면이 얇기 때문에 좌굴에 취약하다는 단점이 있다. 또한 테두리 보나 보에 이웃하는 경간의 길이가 상이할 경우 비대칭 하중에 의해 보에 비틀림이 유발될 가능성이 크다. 이러한 좌굴이나 비틀림은 구조물의 사용성과 밀접한 관계가 있으므로 이를 최소화할 필요가 있다. H-steel is usually used in steel structures. However, in beams composed of H-beams, the web has a disadvantage in that it is vulnerable to buckling because the cross section of the member is relatively thin. In addition, if the length of the edge beams or spans adjacent to the beams is different, it is likely that the beams are twisted by asymmetrical loads. This buckling or torsion is closely related to the usability of the structure and needs to be minimized.

본 발명은 상기한 제반사정을 감안하여 창작된 것으로, 본 발명이 해결하고자 하는 과제는 콘크리트 타설시 거푸집의 역할을 함과 동시에 콘크리트 경화후 콘크리트와 합성되어 일체로 거동하며 좌굴 및 비틀림에 대한 저항성을 향상시킨 조립보를 제공하는 데 있다.The present invention was created in view of the above-mentioned matters, and the problem to be solved by the present invention is to act as a formwork when placing concrete, and to be integrated with concrete after hardening of concrete and to resist buckling and torsion. It is to provide an improved assembly beam.

본 발명의 적절한 실시형태에 따르면, 골이 면에 수직한 방향으로 길이방향을 따라 연속적으로 반복되도록 얇은 강판을 절곡하여 성형되고 서로 이격되어 배치되어 콘크리트가 타설되는 공간을 형성하는 한 쌍의 웨브판과, 한 쌍의 웨브판의 하면에 접합되는 하부 플랜지판을 포함하는 것을 특징으로 하는 골형 웨브 강판 조립보가 제공된다.According to a preferred embodiment of the present invention, a pair of web plates are formed by bending thin steel plates so that the valleys are continuously repeated along the longitudinal direction in a direction perpendicular to the plane, and are spaced apart from each other to form a space in which concrete is poured. And a lower flange plate joined to the lower surface of the pair of web plates is provided.

본 발명의 다른 적절한 실시형태에 따르면, 한 쌍의 웨브판의 상면에 각각 결합되며 하면판과 하면판의 일단에서 수직하게 상향 절곡된 측면판으로 구성되고 측면판에는 복수의 구멍이 천공된 한 쌍의 L형강을 더 포함하는 것을 특징으로 하는 골형 웨브 강판 조립보가 제공된다.According to another suitable embodiment of the present invention, a pair of side plates each joined to the top surface of the pair of web plates and composed of a side plate bent vertically upward at one end of the bottom plate and the bottom plate and having a plurality of holes perforated in the side plate Corrugated web steel plate assembly is provided, characterized in that it further comprises an L-shaped steel.

본 발명의 또 다른 적절한 실시형태에 따르면, L형강을 구성하는 측면판에 형성된 구멍을 관통하여 결합되어 한 쌍의 L형강을 서로 연결하여 웨브판이 벌어지는 것을 구속하는 간격유지재를 더 포함하는 것을 특징으로 하는 골형 웨브 강판 조립보가 제공된다.According to another suitable embodiment of the present invention, it characterized in that it further comprises a spacer for coupling through a hole formed in the side plate constituting the L-shaped steel to connect a pair of L-shaped steel to each other to restrain the web plate from opening A corrugated web steel plate assembly beam is provided.

본 발명의 또 다른 적절한 실시형태에 따르면, 간격유지재는 전체길이에 걸쳐 나사가 가공된 전나사볼트와 그 양단부에 각각 결합되는 너트를 포함하는 것을 특징으로 하는 골형 웨브 강판 조립보가 제공된다.According to another suitable embodiment of the present invention, there is provided a bone web steel plate assembly beam, characterized in that the spacing member includes a full threaded bolt machined over its entire length and a nut coupled to both ends thereof.

본 발명에서는 웨브를 골형강판(파형강판)으로 구성함에 따라 콘크리트와의 기계적인 맞물림 작용으로 웨브판과 콘크리트 사이의 경계면에서의 상대변위(slip)를 방지하여 이들이 일체로 합성될 수 있다. 또한 웨브를 한 쌍의 골형강판으로 구성함에 따라 기존의 철골보에 비해 좌굴 및 비틀림에 대한 저항력을 향상된다. In the present invention, as the web is composed of a corrugated steel sheet (corrugated steel sheet), by mechanical engagement with the concrete to prevent relative slip (lip) at the interface between the web plate and the concrete can be synthesized integrally. In addition, as the web is composed of a pair of corrugated steel sheet, the resistance to buckling and torsion is improved as compared to the conventional steel beam.

이하, 첨부된 도면을 참조하며 본 발명의 바람직한 일 실시 예를 상세히 설명하기로 한다. 도면들 중, 동일한 구성요소 또는 부품들은 가능한 한 동일한 참조부호를 표기하며, 관련된 공지기능 혹은 구성에 대한 구체적인 설명은 생략한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. In the drawings, the same components or parts are denoted by the same reference numerals as much as possible, and detailed descriptions of related known functions or configurations are omitted.

도 1은 본 발명의 일 실시 예에 따른 조립보를 나타낸 사시도이다.1 is a perspective view showing an assembly beam according to an embodiment of the present invention.

도 1을 참조하면, 본 발명의 일 실시 예에 따른 조립보는 골이 면에 수직한 방향으로 길이방향을 따라 연속적으로 반복되도록 얇은 강판을 절곡하여 성형한 웨브판(110a)(110b)을 서로 이격하여 배치하고 그들의 하면에 하부 플랜지 역할을 하는 평판(하부 플랜지판, 120)을 용접하여 조립한 것이다. 본 발명에 있어 조립보는 콘크리트 타설을 위한 거푸집의 역할을 하며 콘크리트가 경화된 후에도 제거되지 않고 콘크리트와 일체로 합성되어 외력에 저항하게 된다. 이에 따라 본 발명에서는 웨브를 골형강판(파형강판)으로 구성하여 콘크리트와의 기계적인 맞물림 작용으로 웨브판과 콘크리트 사이의 경계면에서의 상대변위(slip)를 방지하여 이들이 일체로 합성되도록 하였다. 또한 웨브를 한 쌍의 골형강판으로 구성함에 따라 기존의 철골보에 비해 좌굴 및 비틀림에 대한 저항력을 향상시켰다. 웨브판(110a)(110b)은 예컨데 냉간압연(cold-rolling)으로 만들어질 수 있으며 골의 형상은 도시된 "V' 자형 또는 "W"자형에 한정되지 않으며 둥근형상으로 구성될 수 있다. Referring to FIG. 1, the assembly beam according to an embodiment of the present invention is spaced apart from each other by bending web plates 110a and 110b formed by bending thin steel plates so that the valley is continuously repeated in the longitudinal direction in a direction perpendicular to the plane. And a flat plate (lower flange plate 120) serving as a lower flange on their lower surface is assembled by welding. In the present invention, the assembly beam serves as a formwork for concrete casting and is not removed even after the concrete is cured, and is integrated with the concrete to resist external forces. Accordingly, in the present invention, the web is composed of a corrugated steel sheet (corrugated steel sheet) to prevent relative displacement (slip) at the interface between the web plate and the concrete by mechanical engagement with the concrete so that they are integrally synthesized. In addition, as the web is composed of a pair of corrugated steel sheet, the resistance to buckling and torsion is improved as compared to the conventional cheolgolbo. The web plates 110a and 110b may be made of, for example, cold-rolling, and the shape of the valleys is not limited to the "V" shape or the "W" shape, but may be configured in a round shape.

도 2a는 본 발명의 다른 실시 예에 따른 조립보를 나타낸 분해사시도이고 도 2b는 결합사시도이다.Figure 2a is an exploded perspective view showing an assembly beam according to another embodiment of the present invention and Figure 2b is a combined perspective view.

본 발명에 따른 조립보에는 슬래브 콘크리트를 타설하기 위한 거푸집이 거치된다. 전술한 실시 예에 따르면 웨브가 얇은 강판을 성형한 골형강판으로 구성됨에 따라 슬래브 거푸집을 웨브판 상부에 거치하기가 곤란한 점이 있다. 따라서 본 실시 예에서는 웨브판(110a)(110b)의 상면에 각각 하면판(210)과 하면판(210)의 일단에서 수직하게 상향 절곡된 측면판(220)으로 구성되는 한 쌍의 L형강(20a)(20b)을 그 지간 전체에 걸쳐 접합하였다. 한 쌍의 L형강(20a)(20b)은 측면판(220)이 서로 마주보고 하면판(210)이 외측으로 돌출되도록 결합된다. 하면판(210)이 수평으로 돌출되게 형성되므로 슬래브 거푸집을 거치하기가 용이해 진다. 그리고 측면판(220)에는 그 길이방향을 따라 복수의 관통공(221)을 형성하여 콘크리트가 유동할 수 있도록 하였다. 관통공(221)은 이러한 목적 이외에 후술하는 바와 같이 간격유지재(30)가 관통되어 서로 마주보는 L형강(20a)(20b)을 서로 연결시키기 위한 목적으로도 사용된다. L형강(20a)(20b)은 각각 웨브판(110a)(110b) 상면에 용접으로 접합된다. The assembly beam according to the present invention is equipped with formwork for pouring slab concrete. According to the embodiment described above, it is difficult to mount the slab formwork on the upper portion of the web plate as the web is composed of a corrugated steel sheet formed with a thin steel sheet. Therefore, in the present embodiment, a pair of L-shaped steels composed of a lower plate 210 and a side plate 220 vertically bent upward at one end of the lower plate 210 on the upper surfaces of the web plates 110a and 110b, respectively ( 20a) and 20b were joined all over the space. The pair of L-shaped steels 20a and 20b are coupled such that the side plates 220 face each other and the bottom plate 210 protrudes outward. Since the lower plate 210 is formed to protrude horizontally, it becomes easy to mount the slab formwork. In addition, the side plates 220 are formed with a plurality of through holes 221 along the longitudinal direction thereof to allow concrete to flow. The through hole 221 is also used for the purpose of connecting the L-shaped steel (20a, 20b) facing each other through the gap retaining material 30, as described below in addition to this purpose. The L-shaped steels 20a and 20b are respectively welded to the upper surfaces of the web plates 110a and 110b.

도 3a는 본 발명의 또 다른 실시 예에 따른 조립보를 나타낸 분해사시도이고 도 3b는 결합사시도이다.Figure 3a is an exploded perspective view showing an assembly beam according to another embodiment of the present invention and Figure 3b is a combined perspective view.

위에서 살펴본 바와 같이 본 발명에 따른 조립보는 일종의 거푸집 역할을 하므로 콘크리트 타설시 벌어짐을 구속할 필요가 있다. 이를 위해 본 실시 예에서는 조립보의 길이방향을 따라 일정 간격을 두고 간격유지재(30)를 더 설치하였다. 간격유지재(30)는 전체길이에 걸쳐 나사가 가공된 전나사볼트(310)와 그 양단부에 각각 결합되는 너트(320)로 구성된다. 전나사볼트(310)로 L형강(20a)(20b)을 구성하는 측면판(220)에 형성된 구멍(221)을 관통시키고 그 양단부에 각각 너트(320)를 결합시킴에 따라 간격유지재(30)가 한 쌍의 L형강(20a)(20b)을 서로 연결하게 되므로 콘크리트 타설시 웨브판(110a)(110b)이 벌어지는 것을 방지할 수 있다. 그리고 전나사볼트(310)를 적용함에 따라 서로 마주보는 L형강(20a)(20b) 사이의 이격거리에 관계없이 사용할 수 있는 잇점이 있다.As described above, since the assembly beam according to the present invention serves as a form of formwork, it is necessary to restrain the gaps during concrete pouring. To this end, in the present embodiment, a spacing maintaining material 30 is further installed at regular intervals along the longitudinal direction of the assembly beam. The gap retaining material 30 is composed of a total screw bolt 310 machined over its entire length and a nut 320 coupled to both ends thereof. As the threaded thread 310 passes through the holes 221 formed in the side plates 220 constituting the L-shaped steels 20a and 20b, and the nuts 320 are coupled to both ends thereof, the gap retaining material 30 ) Connects a pair of L-shaped steel (20a) (20b) with each other to prevent the web plate (110a) (110b) to spread when the concrete is placed. In addition, there is an advantage that can be used irrespective of the separation distance between the L-shaped steel (20a, 20b) facing each other by applying the front screw bolt (310).

도 4는 도 3a, 3b에 도시된 조립보의 사용상태를 보여주는 단면도이다.4 is a cross-sectional view showing a state of use of the assembly beam shown in Figures 3a, 3b.

본 발명에 따른 조립보의 사용방법을 도 3a, 3b에 도시된 조립보를 이용하여 설명하면 다음과 같다. The method of using the assembled beam according to the present invention will be described using the assembled beams shown in FIGS. 3A and 3B.

먼저, 골이 면에 수직한 방향으로 길이방향을 따라 연속적으로 반복되도록 얇은 강판을 절곡하여 웨브판(110a)(110b)을 성형하고 성형된 웨브판(110a)(110b)을 하부 플랜지판(120) 위에 콘크리트가 타설된 공간을 형성하도록 서로 이격하여 용접 접합하며, 웨브판(110a)(110b) 상면에 하면판(210)과 하면판(210)의 일단에서 수직하게 상향 절곡된 측면판(220)으로 구성되는 한 쌍의 L형강(20a)(20b)을 각각 용접 접합한 후 전나사볼트(310)로 L형강(20a)(20b)을 구성하는 측면판(220)에 형성된 구멍(221)을 관통시키고 그 양단부에 각각 너트(320)를 결합시켜 한 쌍의 L형강(20a)(20b)을 서로 연결시킨다. First, the thin plate is bent so that the valley is continuously repeated along the longitudinal direction in the direction perpendicular to the surface to form the web plates 110a and 110b and the formed web plates 110a and 110b are lower flange plates 120. Spaced apart from each other by welding to form a space in which the concrete is poured on the side plate, the side plate 220 bent vertically upward at one end of the bottom plate 210 and the bottom plate 210 on the upper surface of the web plate (110a) (110b) A hole 221 formed in the side plate 220 constituting the L-shaped steel 20a, 20b with the full-thread bolt 310 after welding a pair of L-shaped steel 20a, 20b, respectively. Penetration through and the nut 320 is coupled to both ends thereof to connect a pair of L-shaped steel (20a, 20b) to each other.

다음으로 이상과 같이 조립된 조립보를 기둥이나 벽체 위에 거치시키고 L형강(20a)(20b)의 하면판(210)에 슬래브 거푸집(미도시)를 거치한 후 슬래브 철근을 배근하고 조립보 내부에 채워질 콘크리트와 슬래브 콘크리트를 동시에 타설한다. 따라서 본 발명에 따른 조립보는 콘크리트 타설 및 경화시까지 거푸집으로서 기능하게 되며 또한 콘크리트 경화후에는 그 내부에 채워지는 콘크리트와 웨브판(110a)(110b)과의 기계적인 맞물림 작용으로 경계면에서의 상대변위(slip)가 발생되지 않아 외력에 대해 일체로 거동하는 강-콘크리트 합성보가 된다. 미설명부호 "40"은 슬래브를 나타낸다.Next, the assembly beam assembled as above is mounted on a column or a wall, and the slab formwork (not shown) is mounted on the bottom plate 210 of the L-shaped steel 20a, 20b. Cast concrete and slab concrete at the same time. Therefore, the assembly beam according to the present invention functions as a formwork until concrete placement and hardening, and after the concrete hardening, the relative displacement at the interface by the mechanical engagement between the concrete and the web plates 110a and 110b filled therein. No slip occurs, resulting in a steel-concrete composite beam that behaves integrally with external forces. Reference numeral “40” indicates a slab.
