측면수직강판(40)은 상하부강판(20)(30) 사이에 용접구성되며, 측면수직강판(40)에는 수직방향으로 돌출부(41)와 요입부(42)가 교호로 반복된 요철(43)이 구성되어 있으며, 상기 측면수직강판(40) 양측 단부에는 평판형의 수직보강판(44)이 용접구성되어 있고, 상기 수직보강판(44)을 통하여 측면수직강판(40)과 연결플랜지(50)가 일체형으로 연결구성된다.The side vertical steel plate 40 is welded between the upper and lower steel plates 20 and 30, and the side vertical steel plate 40 has protrusions 41 and recesses 42 alternately repeated vertically in the vertical direction. The side vertical steel plate 40 is formed on both ends of the plate-shaped vertical reinforcement plate 44 is welded, and through the vertical reinforcement plate 44 side vertical steel plate 40 and the connecting flange 50 ) Is integrally connected.

상기 측면수직강판(40)에 구성되는 요철(43)은 도면에 도시된 바와 같이 만곡형으로 구성되게 하거나, 도면에는 도시되어 있지 않으나 각형으로 요철이 구성되게 할 수도 있으며, 측면수직강판(40) 양측 단부에 구성되는 수직보강판(44)의 두께는 측면수직강판(40)의 두께보다 두껍게 구성하여, 콘크리트 몰탈 타설시 취약해지기 쉬운 측면수직강판(40)의 양측단부를 보강케 하는 것이 바람직하다.Concave-convex 43 formed in the side vertical steel plate 40 is to be configured as a curved shape, as shown in the drawing, or not shown in the figure may be configured to be concave-convex in a square, side vertical steel sheet 40 The thickness of the vertical reinforcing plate 44 formed at both ends is configured to be thicker than the thickness of the side vertical steel plate 40, it is preferable to reinforce both side ends of the side vertical steel plate 40 tends to be vulnerable during concrete mortar casting. Do.

상기에서 수직보강판(44)의 두께정도는 측면수직강판(40)의 두께보다 1.5~5배정도의 두께로 사용하는 것이 바람직하며, 이는 수직보강판(44)의 두께가 1.5배 이하이면 측면 수직보강판(40)의 보강기능이 떨어지고, 5배이상이면 강판재료의 낭비를 초래하기 때문에 바람직하지 않다.In the above, the thickness of the vertical reinforcing plate 44 is preferably used to a thickness of about 1.5 to 5 times the thickness of the side vertical steel plate 40, which is the side vertical if the thickness of the vertical reinforcing plate 44 is 1.5 times or less It is not preferable that the reinforcement function of the reinforcing plate 40 is reduced, and if it is 5 times or more, it causes waste of steel sheet material.

하부강판(30) 상면에는 등간격으로 스터드볼트(31)를 돌출구성시키고, 상부강판(20)에는 등간격으로 개방공(22)을 구성하여 강판보(10)의 공간부(11) 내에 콘크리트몰탈을 충진할 수 있게 구성하며, 상부강판(20) 상면 양측에는 스터드볼트(21)가 돌출구성되게 하여서 된 것이다.Stud bolts 31 are projected on the upper surface of the lower steel plate 30 at equal intervals, and the openings 22 are formed on the upper steel plate 20 at equal intervals to allow concrete in the space 11 of the steel plate 10. It is configured to fill the mortar, and the stud bolt 21 is protruded on both sides of the upper surface of the upper steel plate (20).

미설명부호 (70)은 골조기둥, (71)은 연결브라켓, (72)는 연결플랜지, (73)은 데크플레이트, (74)는 볼트, (75)는 너트, (76)은 슬라브층, (77)은 콘크리트보이다.Reference numeral 70 is a frame pillar, 71 is a connection bracket, 72 is a connection flange, 73 is a deck plate, 74 is a bolt, 75 is a nut, 76 is a slab layer, 77 is a concrete beam.

이와 같이 구성된 본 발명의 강판보(10) 역시 건물을 구성하는 골조기둥(70) 사이에 설치한 다음 강판보(10) 상에 데크플레이트(73)를 설치하고, 상기한 상태에서 강판보(10) 및 데크플레이트(73)에 콘크리트 몰탈을 타설하여 슬라브층(76)과 콘크리트보(77)가 성형되게 한다는 것은 종래와 다를바 없다.The steel sheet beam 10 of the present invention configured as described above is also installed between the frame pillars 70 constituting the building, then install the deck plate 73 on the steel sheet beam 10, the steel sheet beam 10 in the above state ) And the mortar cast concrete deck plate (73) to the slab layer 76 and the concrete beam (77) is no different from the conventional.

그러나 본 발명에서 제공하고자 하는 강판보(10)는 종래 일반적으로 사용되고 있던 강판보와 비교하면 다음과 같은 차이가 있다.However, the steel sheet 10 to be provided in the present invention has the following differences compared to the steel sheet beams that are commonly used in the prior art.

즉 종래 일반적으로 사용되고 있는 강판보의 경우 강판보를 구성하는 웨브, 즉 측면수직강판이 평판형의 단순한 강판으로 구성되어 있어, 강판보 내에 콘크리트 몰탈을 충진하게 되면 콘크리트 몰탈의 타설압력에 의해 측면수직강판이 측방향 으로 벌어지게 되는 현상이 발생하게 된다.In other words, in the case of steel plate beams that are generally used, the web constituting the steel plate, that is, the side vertical steel plate is composed of a simple plate-shaped steel plate, and when the concrete mortar is filled in the steel plate beams, This lateral phenomenon occurs.

따라서 종래에는 이러한 현상을 방지하기 위하여 측면수직강판의 두께를 두껍게 하거나, 양측면 수직강판 사이를 다수개의 간격유지용 버팀대로 연결하여 지탱케 하여야 하므로 강판보 제작비용이 상승하게 된다.Therefore, in the related art, in order to prevent such a phenomenon, the thickness of the side vertical steel sheet should be thickened, or both sides of the vertical steel plates should be supported by connecting a plurality of gap holding braces to support the steel sheet fabrication cost.

본 발명에서 제공하고자 하는 강판보(10)는 상부강판(20)과 하부강판(30) 사이에 용접구성된 측면수직강판(40)에 수직방향으로 돌출부(41)와 요입부(42)가 형성된 요철(43)이 구성되어 있어, 강판보(10)의 시공시 수직하중에 대한 버팀력이 우수할 뿐 아니라, 특히 강판보(10)의 공간부(11) 내에 콘크리트몰탈을 타설할때 콘크리트몰탈의 타설압력이 측면수직강판(40)에 적용되더라도 돌출부(41)와 요입부(42)로 구성된 요철(43)이 타설압력을 견딜 수 있는 강성을 부여하게 되므로, 측면수직강판(40)의 두께를 얇게 구성하더라도 강판보(10)의 기능에 아무런 문제가 야기되지 않는다.Steel plate 10 to be provided in the present invention is a concave-convex formed projections 41 and concave portion 42 in the vertical direction to the side vertical steel plate 40 welded between the upper steel plate 20 and the lower steel plate 30 (43) is configured, not only is excellent support for the vertical load during construction of the steel sheet beam 10, in particular, when placing concrete mortar in the space portion 11 of the steel sheet beam 10 Even if the placing pressure is applied to the side vertical steel plate 40, the convex and convex portions 43 formed of the protrusions 41 and the concave portion 42 impart rigidity to withstand the placing pressure, thereby increasing the thickness of the side vertical steel plate 40. Even if it is made thin, no problem occurs in the function of the steel sheet beam (10).

상기에서와 같이 상하부강판(20)(30) 사이에 요철(43)이 형성된 측면수직강판(40)을 사용할 경우, 요철(43)이 시작되는 측면수직강판(40)의 양측단부(40')에는 버팀에 대한 강성이 취약하기 때문에 측면수직강판(40) 보다 두꺼운 판재(1.5~3배)로 된 평판형의 수직보강판(44)을 용접구성하여 이를 보강케 하므로서, 강판보(10)를 구성하는 웨브, 즉 측면수직강판(40)에 돌출부(41)와 요입부(42)로 된 요철(43)을 구성하더라도 사용에 장애가 되지 않도록 하였다.As described above, when the side vertical steel plate 40 having the unevenness 43 formed between the upper and lower steel plates 20 and 30 is used, both side ends 40 'of the side vertical steel plate 40 at which the unevenness 43 starts. Since the rigidity for the support is weak, the plate-shaped vertical reinforcement plate 44 made of a plate (1.5 ~ 3 times) thicker than the side vertical steel plate 40, and welded to reinforce it, the steel beam (10) Even if the web constituting the structure, that is, the concave-convex 43 consisting of the protrusion 41 and the concave portion 42 on the side vertical steel plate 40 is not impeded to use.

또한 본 발명의 강판보(10)를 구성하는 상부강판(20)은 하부강판(30)과 함께 요철(43)이 형성된 측면수직강판(40)과 용접되면서 이를 견고히 지탱케 함과 동시 에, 등간격으로 개방공(22)을 뚫어 강판보(10) 내에 구성된 공간부(11)에 콘크리트몰탈이 쉽게 주입될 수 있게 하는 것이며, 상부강판(20)에 뚫린 개방공(22)의 형태 및 크기는 강판보(10)의 크기, 즉 깊이나 폭에 따라 달라질 수 있다.In addition, the upper steel plate 20 constituting the steel sheet 10 of the present invention is welded to the side vertical steel plate 40 with the concavo-convex 43 formed with the lower steel plate 30, while holding it firmly and at the same time, etc. The openings 22 are drilled at intervals so that the concrete mortar can be easily injected into the space 11 formed in the steel sheet 10, and the shape and size of the openings 22 drilled in the upper steel plate 20 are It may vary depending on the size of the steel sheet 10, that is, depth or width.

상하부강판(20)(30)과 측면수직강판(40) 양측단부에는 체결공(51)이 뚫린 연결플랜지(50)가 용접구성되어 있어 강판보(10)를 건물의 골조기둥(70)에 연결하고자 할 때, 상기 연결플랜지(50)를 골조기둥(70)에 용접구성된 연결브라켓(71)의 연결플랜지(72)와 접하게 한 다음 볼트(74)와 너트(75)를 이용하여 체결고정되게 하므로서 골조기둥(70) 상에 강판보(10)의 연결을 신속용이하게 조립할 수 있게 된다.Connection flanges 50 through which fastening holes 51 are drilled are welded at both ends of the upper and lower steel plates 20 and 30 and the side vertical steel plate 40 to connect the steel beams 10 to the frame pillars 70 of the building. When the connection flange 50 is to be brought into contact with the connection flange 72 of the connection bracket 71 welded to the frame pillar 70 and then fastened and fixed using the bolt 74 and the nut 75. It is possible to quickly assemble the connection of the steel beams 10 on the frame pillar (70).
