Description

난연성 구조를 갖는 H 형강{H-beam of flame-resisting with structure}H-beam of flame-resisting with structure < RTI ID = 0.0 >

본 발명은 난연성 구조를 갖는 H 형강에 관한 것으로, 더 상세히는 소정두께의 내화타일을 구비하여 시공성이 뛰어남과 아울러 균일한 내화층을 형성할 수 있는 난연성 구조를 갖는 H 형강에 관한 것이다.
The present invention relates to an H-shaped steel having a flame-retardant structure, and more particularly, to an H-shaped steel having a flame-resistant structure which is provided with a refractory tile having a predetermined thickness and is excellent in workability and capable of forming a uniform refractory layer.

도 1에 도시된 바와 같이, 종래의 '우수한 내화성능을 갖는 친환경 무용제 에폭시 발포성 내화도료 조성물 및 이를 이용한 도장방법' 은 H 형강 상에 방청도료를 포함하는 하도를 도포하는 단계; 상기 하도 상에 제 1항 또는 제 3항 중 어느 한 항에 따른 내화도료 조성물을 도포하여 중도를 형성하는 단계; 및 상기 중도 상에 상도용 도료를 도포하여 상도를 형성하는 단계를 포함하는 것을 특징으로 하는 도장장법이 제공된다.As shown in FIG. 1, a conventional 'environmentally friendly solvent-free epoxy foamable refractory coating composition having excellent fire resistance performance and a coating method using the same' comprises a step of applying a primer containing a rust inhibitive paint on an H-shaped steel; Applying a refractory coating composition according to any one of claims 1 to 3 on the undercoat to form an intermediate layer; And applying a topcoat on the middle surface to form a topcoat.

그리고 상기 중도는 제 1항 내지 제 3항 중 어느 한 항에 따른 내화도료 조성물을 3 내지 4회 도포하여, 10 ~12 mm이상의 두께를 갖는 것을 특징으로 도장방법이 제공된다.And the intermediate layer is coated with the refractory coating composition according to any one of claims 1 to 3 three to four times to have a thickness of 10 to 12 mm or more.

이와 같이, 종래의 '우수한 내화성능을 갖는 친환경 무용제 에폭시 발포성 내화도료 조성물을 이용한 도장방법은 고점도 P.F.P 장비를 이용하여 H 형강의 표면에 3 내지 4회 도포하여 10 ~12 mm이상의 두께를 얻을 수 있다고 하지만, 실질적으로 현장에서 도포작업을 행하다 보면, H 형강의 표면에 3 내지 4회로 도포하는 과정으로는 10 ~12 mm이상의 두께를 얻기 어려워 추가적으로 1회 내지 3회 정도의 도포작업을 추가적으로 행해야만 충분한 규격에 맞는 내화도료의 두께를 얻을 수 있는 것이다. 이처럼 여러번의 내화도료 도포작업을 행하다보니 단가가 상승됨과 아울러 내화도포 도포작업시 바람이나 먼지 등의 주변영향에 의한 작업성이 떨어지는 문제점이 있었다.Thus, the coating method using the environmentally friendly solvent-free epoxy foamable refractory coating composition having excellent fire resistance can be applied to the surface of the H-shaped steel 3 to 4 times using a high-viscosity PFP equipment to obtain a thickness of 10 to 12 mm or more However, when practicing the coating operation in the field, it is difficult to obtain a thickness of 10 to 12 mm or more in the process of applying 3 to 4 times on the surface of the H-shaped steel. It is possible to obtain the thickness of the refractory paint conforming to the standard. As a result of performing the coating work of the refractory paint many times, the unit price is increased and the workability due to the surrounding influences such as wind and dust is lowered during the refractory application work.

도 2는 상기와 같은 방법으로 내화도료를 도포한 모습을 보인 것으로, 상기와 같은 내화도료 도포작업시 내화도료의 균일한 두께를 얻을 수 없는 문제점이 있었다.(도 2는 내화도료 도포작업시 문제점을 제시하기 위해 별도로 첨부된 사진임)
FIG. 2 shows a state in which a refractory coating is applied in the same manner as described above, and there is a problem that a uniform thickness of the refractory coating can not be obtained during the refractory coating operation as described above (FIG. 2) Which is separately attached to present the present invention)

도 3 내지 도 5에 도시된 바와 같이, 본 발명의 난연성 구조를 갖는 H 형강은 H 형강(100)과, 상기 H 형강(100) 상에 도포되는 방청도료층(110)과, 상기 방청도료층(110) 상에 도포되는 제1내화도료층(120)와, 상기 H 형강(100)에 설치되는 내화타일(130)과, 상기 내화타일(130)상에 도포되는 제2내화도료층(150)과, 상기 제2내화도료층(150) 상에 도포되는 마감도료층(160)으로 구성된다.3 to 5, an H-shaped steel having a flame-retardant structure according to the present invention includes an H-shaped steel 100, an anti-corrosive coating layer 110 applied on the H-shaped steel 100, A first refractory layer 120 applied on the refractory tile 110, a refractory tile 130 installed on the H-beam 100, a second refractory layer 150 applied on the refractory tile 130, And a finish coat layer 160 applied on the second refractory coat layer 150.

상기 H 형강(100)은 통상적인 구조 구체적인 설명은 하지 않으며, 이에 한정하지 않고 다양한 철골구조이 적용된 수 있는 것이다.The H-section steel 100 is not limited to a specific structure and is not limited to a typical structure, but may be applied to various steel structures.

상기 방청도료층(110)은 H 형강(100)의 표면에 방청도료를 0.05∼2mm 두께로 구비되는 것이 바람직하다.The anti-corrosive coating layer 110 is preferably provided on the surface of the H-shaped steel 100 with a thickness of 0.05 to 2 mm.

상기 제1내화도료층(120)은 방청도료층(110) 상에 1∼2mm 두께로 내화도료를 도포하는 것이 바람직하다.Preferably, the first refractory layer 120 is applied with a refractory coating having a thickness of 1 to 2 mm on the anticorrosive coating layer 110.

상기 내화타일(130)은 제1내화도료층(120)이 도포된 H 형강(100)의 끝단부에 끼워져 고정되는 단부측 내화부재(131)와, 상기 단부측 내화부재(131) 및 H 형강(100)의 내측에 설치되는 수평판 내화부재(132)와, 상기 수평판 내화부재(132) 사이에 설치되는 수직판 내화부재(133)로 이루어진다.The refractory tile 130 includes an end refractory member 131 that is fixed to an end portion of the H-shaped steel 100 coated with the first refractory layer 120 and an end refractory member 131 which is fixed to the end refractory member 131 and the H- Plate refractory member 132 provided on the inner side of the horizontal plate 100 and a vertical plate refractory member 133 provided between the horizontal plate refractory member 132. [

그리고 상기 내화타일(130)의 내측면에는 일정간격을 두고 요철형상이 구비된다.The inner surface of the refractory tile 130 is provided with irregularities at regular intervals.

이와 같이, 상기 단부측 내화부재(131)는 H 형강(100)의 양측 돌출부에 억지끼움 결합되어 상기 고정돌기(134)에 의해 고정된다.Thus, the end side refractory member 131 is firmly engaged with the protrusions on both sides of the H-shaped steel 100, and is fixed by the fixing protrusions 134.

그리고 상기 내화타일(130)은 9∼15mm 두께로 구비되는 것이 바람직하다. The refractory tile 130 is preferably 9 to 15 mm thick.

여기서 상기 내화타일(130)이 9mm 이하인 경우에는 내화표준 규격에 맞대록 내화도료층을 형성하여야 하기 때문에 추가적인 작업이 요구되는 문제점이 있다. If the refractory tile 130 is 9 mm or less, a refractory paint layer must be formed in accordance with the fire resistance standard, which requires additional work.

또한 내화타일(130)이 15mm 이상인 경우에는 내화타일(130)의 자체 무게에 의해 내화도료와의 접착력이 저하되는 문제점이 있는 것이다.Also, when the refractory tile 130 is 15 mm or more, the adhesion of the refractory tile 130 to the refractory coating is deteriorated due to the own weight of the refractory tile 130.
