본 발명은 내화 성능을 갖는 샌드위치 패널용 연결부재에 관한 것으로, 더욱 상세하게는 연속적으로 조립되는 샌드위치 패널 사이에 설치되어 화재 발생시 화재가 확대됨을 방지하는 내화 성능을 갖는 샌드위치 패널용 연결부재에 관한 것이다.The present invention relates to a sandwich panel connecting member having a fireproof performance, and more particularly to a sandwich panel connecting member having a fireproof performance that is installed between sandwich panels that are continuously assembled to prevent the expansion of fire in the event of a fire. .

주지하는 바와 같이 샌드위치 패널은 양면 도장된 강판 사이에 우수한 단열 성능을 가지는 폴리스티렌폼(Expanded poly-stylene foam), 우레탄폼(Poly-urethane foam), 그라스울(Glass wool) 등을 내장시킨 합성복합자재로써, 건설현장의 인력난, 자재난의 극복 및 건식공법의 적용으로 인한 시공의 편리성을 가져 사용량이 증가하고 있는 건축용 자재이다.As is well known, the sandwich panel is a composite composite material in which polystyrene foam, polyurethane foam, glass wool, etc., which have excellent thermal insulation performance between double coated steel sheets, are embedded. It is a building material that has increased in use due to the convenience of construction due to overcoming manpower shortage, material shortage at construction site and application of dry method.

이러한 샌드위치 패널은 공업용 건축 및 창고시설 등의 용도뿐만 아니라 주택 및 냉동 창고, 정밀기계 공장, 전자반도체 공장, 항온항습실 등 그 사용이 확대되고 있는 실정이다.Such sandwich panels are being used not only for industrial construction and warehouse facilities, but also for housing and freezing warehouses, precision machinery factories, electronic semiconductor factories, and constant temperature and humidity rooms.

이와 같은 샌드위치 패널을 도1 및 도2에 도시하였다.Such a sandwich panel is shown in FIGS. 1 and 2.

이에 도시된 바와 같이 샌드위치 패널(100)은 일정 두께를 가지는 강판의 양면에 아연이 도금된 아연도금강판(101)을 제작하고, 이들 아연도금강판(101) 사이에 폴리스티렌폼, 우레탄폼 또는 그라스울 등의 심재(102)를 충진하며, 다수개의 샌드위치 패널(100)이 연속적으로 조립되도록 샌드위치 패널(100)의 일측 단부에 심재(102) 보다 아연도금강판(101)의 길이를 더 돌출시킨 접합부(103)를 형성하고, 이에 다수개의 리벳(104)이 삽입되도록 통공(105)을 형성한다.As shown in the drawing, the sandwich panel 100 fabricates zinc plated galvanized steel plates 101 on both sides of a steel plate having a predetermined thickness, and polystyrene foam, urethane foam or glass wool, etc., between the galvanized steel sheets 101. Filling the core material 102, the joint portion 103 protruding the length of the galvanized steel sheet 101 more than the core material 102 at one end of the sandwich panel 100 so that a plurality of sandwich panels 100 are continuously assembled. ) To form a through-hole 105 so that a plurality of rivets 104 are inserted thereto.

아울러 샌드위치 패널(100)의 타측 단부에 접합부(103)와 대응되어 이에 삽입되도록 아연도금강판(101)을 접합부(103)의 길이만큼 절곡하여 돌출접합부(106)를 형성하고, 이에 통공(105)과 동일한 위치에 대응되는 통공(107)을 형성한다.In addition, the galvanized steel sheet 101 is bent by the length of the junction portion 103 to correspond to the junction portion 103 at the other end of the sandwich panel 100 so as to be inserted therein, thereby forming a protruding junction portion 106, thereby through-hole 105. To form a through hole 107 corresponding to the same position.

이와 같은 샌드위치 패널(100)을 시공하기 위하여 금속 골조 사이의 H형 포스트 또는 조임 철물 등에 샌드위치 패널(100)의 일측을 견고하게 고정시키고, 접 합부(103) 내측으로 다른 샌드위치 패널(100)의 돌출접합부(106)를 삽입시켜 접합부(103)와 돌출접합부(106)에 형성된 통공(105,107)을 일치시킨 다음 이에 리벳(104)을 고정시킨다.In order to construct such a sandwich panel 100, one side of the sandwich panel 100 is firmly fixed to an H-type post or a fastening hardware between metal frames, and the other sandwich panel 100 protrudes into the joint 103. Insertion of the junction 106 to match the through-holes 105, 107 formed in the junction 103 and the projecting junction 106, and then fix the rivet 104.

이와 같이 다수개의 샌드위치 패널(100)을 연속적으로 시공함으로써 공장 건축물, 냉동창고, 주차타워, 상가 및 전시장 등을 간편하면서도 신속하게 시공하게 되는 이점은 있으나, 일측방에서 리벳(104)을 박아 고정시키므로 접합부(103)와 돌출접합부(106)가 긴밀하게 고정되지 못하며, 리벳(104)이 외부에 보여지므로 미관상 미려하지 못하게 되는 단점이 있다.As described above, by continuously constructing a plurality of sandwich panels 100, there is an advantage that the construction of a factory building, a freezer warehouse, a parking tower, a shopping mall and an exhibition hall can be easily and quickly installed, but the rivet 104 is fixed at one side. The junction 103 and the projecting junction 106 are not tightly fixed, and since the rivet 104 is seen from the outside, there is a disadvantage in that it is not aesthetically beautiful.

이와 함께 접합부(103)와 돌출접합부(106)의 심재(102)가 맞닿아 있으므로, 화재 발생시 접합부(103,106)로 화염의 유입 및 인접한 장소에서 발생된 화재의 열이 열전도 되어 심재가 용융되면서 2차 화재를 발생시키게 되는 우려가 있으며, 리벳(104)으로 고정되는 접합부(103,106)의 결합상태가 취약하므로 화재에 의해 샌드위치 패널이 변형되어 구조물을 견고하게 유지시키지 못하게 되는 문제점이 있다.In addition, since the joint 103 and the core 102 of the protruding joint 106 abut each other, when the fire occurs, the inflow of the flame into the joint 103 and 106 and heat of the fire generated in the adjacent place are thermally conductive and the core is melted. There is a risk of generating a fire, there is a problem that the sandwich panel is deformed by the fire, so that the joint state of the joints 103 and 106 fixed by the rivets 104 is weak, so that the structure cannot be firmly maintained.

상기와 같은 문제점을 해결하기 위하여 안출된 본 발명의 목적은 샌드위치 패널의 접합부 사이에 무기질로 이루어진 연결부재를 삽입시켜 화재 발생시 화재가 번지는 것을 방지하는 내화 성능을 갖는 샌드위치 패널용 연결부재를 제공하는 데 있다.An object of the present invention devised to solve the above problems is to provide a sandwich panel connecting member having a fire-resistant performance to prevent the spread of fire in the event of a fire by inserting a connecting member made of inorganic material between the joints of the sandwich panel.

In the end portion, the joint portion is bent in the same width as the inorganic connection member 20 of the galvanized steel sheet protruding from the core material and the protruding joint portion bent in the same width as the connecting member the zinc plated steel sheet protruding from the core material at the other end A sandwich panel connecting member having a fire resistance performance is provided, which is formed between the formed sandwich panel and the core member of the assembled joint, and a connecting member formed of a hollow portion with an inorganic material such as cement or ceramic.

이와 같이 하여 본 발명은 샌드위치 패널의 접합부를 긴밀하게 밀착됨과 함께 변형방지판 및 마감캡에 의하여 화염이 유입되는 통로를 2중으로 차단하여 심재가 연소되는 2차 화재 발생을 방지하게 되고, 금속 재질의 보강재인 변형방지판에 의하여 샌드위치 패널 접합부의 형태적인 변형을 방지하며, 무기질 재료인 연결부재에 의하여 인접한 샌드위치 패널에 화재의 번짐을 차단하여 화재가 확대됨을 방지하게 되는 유용한 효과가 있다.In this way, the present invention is in close contact with the junction of the sandwich panel, and by blocking the passage of the flame inlet by the deformation preventing plate and the closing cap in double to prevent the secondary fire occurrence of the core material is burned, The deformation preventing plate, which is a reinforcing material, prevents the deformation of the sandwich panel joint and prevents the spread of the fire by preventing the spread of the fire on the adjacent sandwich panel by the connecting member, which is an inorganic material.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도시된 바와 같이 본 발명은 일측 단부에 심재(11) 보다 돌출된 아연도금강판(12)을 내측으로 절곡시킨 접합부(13)를 형성하고, 타측 단부에 심재(11) 보다 돌출된 아연도금강판(12)을 내측으로 절곡시킨 돌출접합부(14)를 형성한 샌드위치 패널(10)과, 접합부(13,14)와 동일한 폭으로 이루어져 내부에 공간이 형성된 중공 형태의 무기질계 연결부재(20)와, 절곡된 접합부(13,14)의 내측으로 삽입되는 변형방지판(30)과, 변형방지판(30)에 씌워지는 마감캡(40)으로 이루어진다.As shown, the present invention forms a joint 13 bent inward to the galvanized steel sheet 12 protruding from the core 11 at one end, and the galvanized steel sheet protruding from the core 11 at the other end ( A sandwich panel 10 having a protruding junction 14 bent inwardly 12, a hollow inorganic connection member 20 having the same width as the junction 13 and 14 and having a space therein; The deformation preventing plate 30 is inserted into the bent joints 13 and 14 and the closing cap 40 is covered by the deformation preventing plate 30.

아울러 샌드위치 패널(10)의 양측 접합부(13,14)는 절곡된 부위까지 심재(11)를 충진하되, 심재(11) 보다 돌출된 아연도금강판(12)을 조립되게 절곡한다.In addition, the side joints 13 and 14 of the sandwich panel 10 fill the core material 11 to the bent portion, and bend the assembled galvanized steel sheet 12 protruding from the core material 11.

또한, 무기질계 연결부재(20)는 이의 재질을 시멘트, 무기섬유, 고밀도 세라믹 등의 무기질계 재질로 성형하며, 내부에 공간부(21)를 형성한 중공 형태로 성형하는 형태도 가능하다. 이와 함께 변형방지판(30)은 접합부(13,14)에 삽입되어 샌드위치 패널(10)의 지지 강도를 보강하도록 금속 재질로 이루어지며, 마감캡(40) 또한 금속 재질로 이루어진다.In addition, the inorganic connection member 20 is formed of an inorganic material such as cement, inorganic fibers, high-density ceramics, and the like, and may be formed into a hollow shape in which a space 21 is formed therein. In addition, the deformation preventing plate 30 is made of a metal material to be inserted into the joints (13, 14) to reinforce the support strength of the sandwich panel 10, the closing cap 40 is also made of a metal material.

이와 같은 구성으로 이루어진 본 발명은 샌드위치 패널(10)의 일측을 H형 포스트 또는 조임 철물 등에 견고하게 고정시키고, 타측 단부의 접합부(13)에 중공형태로 된 무기질계 연결부재(20)를 끼운 다음 다른 샌드위치 패널(10)의 돌출접합부(14)를 끼우게 된다. 이러한 무기질계 연결부재(20)는 접합부(13,14)의 폭과 동일하므로 심재(11)와 심재(11) 사이에 위치하게 된다.According to the present invention having such a configuration, one side of the sandwich panel 10 is firmly fixed to an H-type post or a fastening hardware, and the like, and then the inorganic connection member 20 in the hollow form is inserted into the joint 13 at the other end. The sandwiching portion 14 of the other sandwich panel 10 is fitted. Since the inorganic connection member 20 is the same as the width of the junction (13, 14) is located between the core material 11 and the core material (11).

이와 같이 접합부(13,14)가 조립되면 접합부(13,14)에 다단으로 절곡된 변형방지판(30)을 끼워 넣은 다음 변형방지판(30)의 외측에서 나사못(31)을 체결함으로써 변형방지판(30), 아연도금강판(12) 및 무기질계 연결부재(20)를 긴밀하게 밀착되도록 체결된다. 이러한 아연도금강판(12), 무기질계 연결부재(20) 및 변형방지판(30)에 미리 체결공(25)을 형성하여 나사못(31)의 체결을 용이하게 할 수 있음은 물론이다.When the joints 13 and 14 are assembled as described above, the deformation preventing plate 30 bent in multiple stages is inserted into the joints 13 and 14, and then the screw 31 is fastened from the outside of the deformation preventing plate 30 to prevent deformation.
