Abstract

PURPOSE: Provided is a method for fire-resisting a section steel material useable as a structural device such as column or girder of steel structures by applying evaporation heat of water to inhibit temperature raise and to improve fire-resistant performance. CONSTITUTION: The method comprises applying a section steel material(10) to form a framework of a steel structure; a concrete(20) introduced into a spatial area(12) of the section steel for a purpose of fire-resistance; and a space(30) to store water supplied from a port(40). Alternatively, the spatial area itself may be used as the space(30) to contain water. The method is based on application of the evaporation heat generated by the water contained the space(30) and requires neither application of fire-proof coating material nor introduction of concrete surround common H shaped steels.

Description

물의 기화열을 이용한 형강부재의 내화방법{The method of fire resistance for the steel by using the evaporation heat of water}Refractory method of the steel member using the heat of vaporization of water {The method of fire resistance for the steel by using the evaporation heat of water}

본 발명은 철골구조물의 기둥이나 보 등과 같은 구조부재로 사용되는 형강부재에 있어서, 보다 상세하게는 형강부재의 공간부에 내화목적으로 타설되는 콘크리트 내에 물을 넣음으로써 형강부재의 내화성능을 향상시키는 방법에 관한 것이다.The present invention is to improve the fire resistance performance of the steel member by inserting the water in the concrete, which is poured for the refractory purpose of the steel member used in the structural member, such as pillars or beams of steel structures, more specifically It is about a method.

건축물에 사용되는 구조용 강재는 500～600 C의 온도에서 강도가 1/2로 감소하고 항복강도도 급격히 감소하며, 탄성계수도 65% 수준으로 급격히 저하된다. 따라서 화재발생으로 구조용 강재의 온도가 500～600 C에 이르게 되면 건축물이 붕괴되어 버리게 된다.Structural steels used in buildings have a decrease in strength by half, yield strength decreases rapidly, and elastic modulus decreases to 65%. Therefore, when the temperature of structural steel reaches 500 ~ 600 C due to the fire, the building collapses.

이에 따라 건축구조물 건축시 거주자의 인명 및 건축구조물의 보호를 위해 구조용 강재의 표면에 내화 피복제를 도포하거나 또는 석면으로 감싸주어 열전도를 약화시키도록 하는 내화구조가 제도화되어 있다. 그리고 이러한 방법 이외에도 각 형강재의 내, 외부에 콘크리트를 타설하는 방법도 있다. 그러나 종래에 사용된 내화 피복제는 피부접촉 시 발진 및 염증을 유발시키고 분진을 장기간 흡입 시 폐질환을 가져올 수 있는 문제점이 있다.Accordingly, in order to protect the lives of residents and building structures during construction of the building structure, a fireproof structure is applied to the surface of the structural steel in order to reduce heat conduction by applying a fireproof coating or wrapping it with asbestos. In addition to these methods, there is also a method of pouring concrete inside and outside each section steel. However, conventionally used refractory coatings have problems such as rash and inflammation upon skin contact and pulmonary disease when prolonged inhalation of dust.

종래에 이용되고 있는 방법 중에서 특히 콘크리트를 타설하는 방법이 주로 이용되고 있는 실정이나 통상적으로 행해지고 있는 작업과정을 살펴보면 먼저 철골구조물의 기둥과 보를 일차적으로 조립한 상태에서 그 사방 둘레로 내화용 콘크리트를 타설하기 위한 거푸집을 설치하고 이에 콘크리트를 부어 기둥이나 보를 포설하도록 하였기 때문에 거푸집을 설치하는 작업이 복잡하고 어려울 뿐만 아니라 골조형 강재의 주변을 전체적으로 콘크리트를 포설 함으로써 부대 설비 비용의 증가는 물론 고정하중의 증가, 많은 작업시간의 소요 등의 문제가 있다.Among the methods used in the related art, in particular, the method of pouring concrete is mainly used, but the working process is generally performed. First, the fireproof concrete is poured around all four sides of the steel structure columns and beams. Since the formwork is installed and concrete is poured to install columns or beams, it is not only complicated and difficult to install the formwork, but also the installation of concrete as a whole around the framed steel, thereby increasing the cost of supporting equipment and increasing the fixed load. , It takes a lot of work time, etc.

본 발명은 이와 같은 종래의 제반 결점을 해결하기 위하여 발명한 것으로서, 본 발명의 목적은 철골구조물의 기둥이나 보 등과 같은 구조 부재로 사용되는 형강부재의 공간부에 타설되는 콘크리트 내에 물을 넣어 형강부재의 내화성능을 향상시켜 줌으로써 추가로 형강부재 둘레에 타설되는 콘크리트나 내화 피복제를 없애거나 줄일 수 있는 물의 기화열을 이용한 형강부재의 내화 방법을 제공함에 있다.The present invention has been invented to solve the above-mentioned general drawbacks, the object of the present invention is to put the water in the concrete to be poured into the space of the steel member used as a structural member, such as pillars or beams of steel structures It is to provide a fireproof method of the steel member using the heat of vaporization of water to remove or reduce the concrete or fireproof coating to be poured around the steel member by improving the fire resistance of the.
