And inserted into the upper end of the steel structure stair connecting plate 101, and the bolt is inserted into the other groove 32 is fixed to the steel structure connecting plate 101, and formed in the handrail support (11) The fastening structure of the staircase steel safety railing, characterized in that the '∪'-shaped fixture 41 for supporting the handrail rod 201 is inserted into the plurality of fixed grooves 12 to be fixed by the butterfly nut 42. To provide.

본 고안의 또 다른 특징으로는 난간지주대(11)에 성형된 각 쌍의 고정홈(12)중 아래쪽에 성형된 고정홈(12)이 횡방향의 '一'자형 형상으로 성형되되, 중앙으로부터 양측으로 갈수록 상향되는 형상으로 구비되는 것을 특징으로 한다.Another feature of the present invention is that the fixing grooves 12 formed at the bottom of each pair of fixing grooves 12 formed on the handrail holder 11 are formed in a 'one' shape in the transverse direction, from the center It is characterized in that it is provided in a shape that is upward toward both sides.

상기와 같은 구성을 가지는 본 고안에 따른 안전난간 체결구조를 하기에 첨부된 도면을 참조하여 보다 상세히 살펴보면 다음과 같다.With reference to the accompanying drawings, the handrail fastening structure according to the present invention having the configuration as described above in more detail as follows.

도 2는 본 고안에 따른 안전난간의 전체사시도이고, 도 3은 본 고안에 따른 안전난간의 분리사시도이며, 도 4 및 도 5는 본 고안의 실시예를 나타낸 부분 측면도이고, 도 6은 본 고안에 따른 안전난간의 사용상태도이다.2 is an overall perspective view of the safety railing according to the present invention, Figure 3 is a separate perspective view of the safety railing according to the present invention, Figures 4 and 5 is a partial side view showing an embodiment of the present invention, Figure 6 is the present invention It is a state of use of safety rail according to

본 고안은 건물의 시공시 내부 임시계단의 안전난간으로 사용되는 것으로서, 도 2 내지 도 4에 도시된 것처럼, 철구조물 계단 연결판(101) 상단에 끼워지고 타측 홈(32)에 볼트가 삽입되어 철구조물 계단 연결판(101)에 고정되는 삽입구(31)와, 난간지주대(11)에 삽입된 후 타측에 성형된 홈으로 볼트등의 체결수단이 삽입되어 난간지주대(11)에 고정되는 관통중공끼움구(21)로 구성되고, 상기 끼움구(21) 일측의 나사부(22)가 상기 삽입구(31)의 타측 홈(미도시)에 결합됨으로써, 난간지주대(11)가 철 구조물 계단 연결판(101)의 외주에 고정되게 된다.The present invention is used as a safety railing of the internal temporary staircase during the construction of the building, as shown in Figures 2 to 4, inserted into the top of the steel structure stair connecting plate 101 and the bolt is inserted into the other groove 32 Insertion holes 31 fixed to the steel structure stair connecting plate 101 and the handrail is inserted into the handrail holder 11, and then fastening means such as bolts are inserted into grooves formed on the other side and fixed to the handrail holder 11. Comprising a through-hole fitting hole 21, the threaded portion 22 on one side of the fitting hole 21 is coupled to the other groove (not shown) of the insertion hole 31, the railing support 11 is a steel structure staircase It is fixed to the outer circumference of the connecting plate 101.

이때, 상기 난간지주대(11)의 하단에는 양측에 관통공(62)이 성형된 중공끼움편(61)이 삽입ㆍ설치되고, 철구조물 계단 연결판(101) 하단에 끼워진 철나사부(51)가 상기 중공끼움편(61)의 관통공(62)에 관통된 후 너트(53)로 고정됨에 따라 난간지주대(11)의 직립설치가 견고하게 되는 것이다. 난간지주대(11)의 하부에는 또 다른 홈(번호미도시)이 형성돼, 볼트가 상기 홈으로 관통ㆍ삽입되어 철구조물 연결판(101)에 지지됨으로써 보다 견고하게 고정될 수 있는 데, 상기 구조는 필요에 따라 추가될 수 있다.At this time, the lower end of the handrail holder 11 is inserted and installed in the hollow fitting piece 61 formed with the through-hole 62 on both sides, the iron screw portion 51 is inserted into the lower end of the steel structure stair connecting plate 101 As the penetrating through the through-hole 62 of the hollow fitting piece 61 is fixed with a nut 53, the upright installation of the railing support 11 becomes firm. Another groove (not shown) is formed at the lower portion of the railing support 11, and the bolt can be more firmly fixed by being penetrated and inserted into the groove and supported by the steel structure connecting plate 101. The structure can be added as needed.

또한, 난간지주대(11)에 성형된 복수쌍의 고정홈(12)에 난간봉(201)을 지지하기 위한 '∪'자형 고정구(41)가 삽입되어 나비너트(42)로 고정된 후 난간봉(201)이 타이트하게 삽입됨에 따라 계단 철골안전난간의 체결이 완성되는 것이다.In addition, the handrail is inserted into the plurality of fixing grooves 12 formed in the handrail holder 11 to support the handrail rod 201 is fixed to the butterfly nut 42 and then the handrail As the rod 201 is tightly inserted, the fastening of the staircase steel safety railing is completed.

그리고, 상기 본 고안의 안전난간이 경사진 계단에 설치될 경우에, 도 5 및 도 6에 도시된 것처럼 '∪'자형 고정구(41)의 하부는 난간지주대(11)에 형성된 각쌍의 고정홈(12)중 횡방향의 '一'자형으로 성형되어 중앙으로부터 양측으로 갈수록 상향되는 형상의 하측 고정홈(12)에 삽입됨으로써, 우상향 혹은 우하향등 난간봉(201)의 결합방향에 따라 보다 용이하게 설치될 수 있도록 구성된다. 이럴 경우, 철 구조물 연결판(101) 상단에 볼트로 고정된 삽입구(31)는 경사진 계단 철구조물 계단 연결판(101)에 적합하도록 볼트를 조절하여 삽입구(31)의 각도를 적절하게 맞춤으로써, 분리결합이 용이하고 간편하게 설치될 수 있다.In addition, when the safety railing of the present invention is installed on an inclined staircase, as shown in FIGS. 5 and 6, the lower portion of the '∪'-shaped fixture 41 is a pair of fixing grooves formed in the handrail holder 11. (12) of the '12' shape of the transverse direction is inserted into the lower fixing groove 12 of the shape which is upwardly moved from the center to both sides, thereby more easily according to the coupling direction of the handrail rod 201, such as the right upward or downward direction. It is configured to be installed. In this case, the insertion hole 31 fixed to the top of the steel structure connecting plate 101 by adjusting the bolt to fit the inclined stair steel structure stair connecting plate 101 by properly adjusting the angle of the insertion hole 31 by It is easy to separate and install.

상기한 바와 같이 본 고안은 계단의 안전난간을 이루는 각 구성요소들이 분리결합이 용이하도록 구비됨으로써, 영구난간의 설치를 위해 안전난간이 해체된 후에도 상기 철골 안전난간의 구성요소들을 재활용할 수 있게 된다.As described above, the present invention is provided so that each component constituting the safety railing of the staircase is easily separated, so that the components of the steel safety railing can be recycled even after the safety railing is dismantled for the installation of the permanent railing. .

이와 같이 상기한 본 고안에 의하면, 임시 안전난간의 체결구조가 분리결합이 용이한 구조로 이루어지므로, 안전난간의 설치와 해체시 작업의 편리성과 능률을 높여주고, 구성요소 각각의 재활용이 가능함에 따라 설치비용과 시간면에서 경제적인 효과가 있다.As described above, according to the present invention, since the fastening guardrail structure of the temporary safety railing is made of a structure that can be easily separated and coupled, the convenience and efficiency of work during the installation and dismantling of the safety railing can be increased, and each component can be recycled. Therefore, it is economically effective in terms of installation cost and time.
