Abstract

본 발명은 개선된 상판 지지용 클램프구조에 대해 개시한다.The present invention discloses an improved top support clamp structure.

종래 상판 지지용 클램프구조를 스틸박스에 결합시키기 위해서는, 그 양측에 관통구멍을 형성시키거나, 금속막대를 용접시켰는데, 이와 같은 경우, 관통구멍에 의해 그 부위가 그만큼 취약해지게 되고, 시간이 경과함에 따라 용접부위 둘레가 부식되므로 결국 결합부위가 그만큼 부실해지게 되어 안전사고 발생 확률이 증가하였으며, 콘크리트 타설시 클램프구조의 일부가 이에 매설되므로 재활용할 수 없었다.In order to connect the upper plate clamping structure to the steel box, through holes are formed on both sides or welded metal rods. In such a case, the parts become weak due to the through holes. As the weld circumference corroded, the joints eventually became so poor that the probability of safety accidents increased, and when the concrete was placed, part of the clamp structure was buried and could not be recycled.

따라서, 양단 상면에 다수의 요철(12)이 형성되고 단부에 각각 나사구멍(13)이 형성된 지지대(11)와; 스틸박스(2)의 대응 상부에 지지되는 지지부(15)와 지지대(11)의 대응단부에 결합되는 고정부(16)로 이루어지고, 고정부(16) 저면에 지지대(11)의 요철(12)에 치합되도록 다수의 요철(17)이 형성된 연결부재(14)와; 연결부재(14)의 지지부(15)에 씌워지는 캡(18)과; 연결부재(14)의 고정부(16) 및 지지대(11)의 대응 단부에 체결되어 이들을 결합지지시키는 체결수단(19)과; 지지대(11)의 나사구멍(13)에 체결되고 단부가 연결부재(14)의 지지부(15)에 지지되는 지지볼트(25)로 이루어진 상판 지지용 클램프구조를 구비하였다.Therefore, the support base 11 is formed with a plurality of concave-convex (12) on the upper end of both ends and the screw hole (13) formed at each end; It consists of a support portion 15 supported on the corresponding upper portion of the steel box 2 and the fixing portion 16 coupled to the corresponding end of the support 11, the unevenness 12 of the support 11 on the bottom of the fixing portion 16 A connecting member 14 having a plurality of unevennesses 17 formed thereon to be engaged with each other; A cap 18 covered by the support 15 of the connecting member 14; Fastening means (19) fastened to the corresponding ends of the fixing portion (16) and the support (11) of the connecting member (14); It was provided with a clamp structure for supporting the upper plate made of a support bolt 25 fastened to the screw hole 13 of the support 11, the end of which is supported by the support 15 of the connecting member 14.

그러므로, 스틸박스(2)에 관통구멍을 형성시키거나 금속막대를 용접시키지 않고도 이에 지지대(11)를 고정결합시킬 수 있어, 이들의 결합에 의해 스틸박스(2)의 일부가 손상되지 않으므로 결합상태를 더욱 견고하며, 안전사고를 방지시킬 수있을 뿐 아니라, 연결부재(14)의 지지부(15)가 캡(18)에 씌워진 후 스틸박스(2) 상면에 지지되므로 콘크리트가 타설되어 응고되어도 캡(18)만 콘크리트 내부에 매입될 뿐 연결부재(14)는 간단히 분리되므로 콘크리트 타설후 해체작업이 매우 신속하고 편리하며, 클램프를 재활용할 수 있도록 하였다.Therefore, the support 11 can be fixedly coupled to the steel box 2 without forming a through hole or welding a metal rod, so that a part of the steel box 2 is not damaged by the combination thereof. More firmly and can prevent safety accidents, and because the support part 15 of the connecting member 14 is covered by the cap 18 and then supported on the upper surface of the steel box 2, Only the 18 is embedded in the concrete, but the connecting member 14 is simply separated, so that the dismantling work after the concrete is very quick and convenient, and the clamp can be recycled.

Description

상판 지지용 클램프구조{support clamp structure for upper board}Support clamp structure for upper board

본 발명은 고가도로나 건축물의 상판 지지에 관한 것으로, 특히 상판 지지용클램프구조에 관한 것이다.The present invention relates to a top plate support of an overpass or a building, and more particularly, to a top plate clamp structure.

일반적으로 고가도로를 건설하거나 다리를 건설하기 위해서는 먼저, 도로나 다리의 전체를 지지하도록 그 설치방향에 따라 다수의 교각을 등간격으로 설치하고, 이 교각 상부 양측에 스틸박스를 올려 놓는다.In general, in order to construct an overpass or a bridge, first, a plurality of piers are installed at equal intervals according to the installation direction so as to support the entire road or a bridge, and a steel box is placed on both sides of the top of the piers.

스틸박스 사이에 금속의 지지대를 등간격으로 설치하고, 지지대 사이에 격자 모양으로 장선을 설치하며 장선 상부에 상판을 고정지지시킨 후 그 상부에 콘크리트를 타설하게 된다.Metal supports are installed at equal intervals between the steel boxes, and the joists are installed in a lattice shape between the supports, and the upper plate is fixed on the upper parts of the joists, and then concrete is placed on the upper parts.

여기서 지지대의 양단에 대응되는 스틸박스를 고정지지시키기 위해서, 지지대 양단 및 그 단부가 위치되는 스틸박스 양측에 관통구멍을 형성시키고 이 관통구멍에 볼트 및 너트를 체결시켜서 결합시키는 방법과, 스틸박스 양측에 금속막대를 용접한 후 이에 클램프의 걸고리를 걸어서 지지시키는 방법이 사용되었다.Here, in order to fix the steel box corresponding to both ends of the support, through holes are formed on both sides of the support and the steel box in which the ends are located, and the bolts and nuts are fastened to the through holes to be coupled to each other. After welding the metal rod to the hook was used to hang the clamp hook.

그런데 스틸박스 양측에 관통구멍을 형성시킬시, 관통구멍 형성부위가 그만큼 취약해지게 되고, 금속막대를 용접할시 시간이 경과함에 따라 용접부위 둘레가 부식되었으며, 결국 결합부위가 그만큼 부실해지게 되어 안전사고 발생 확률이 증가하였다.However, when the through-holes are formed on both sides of the steel box, the through-hole forming portion becomes weak enough, and as the time passes when the metal rod is welded, the circumference of the welded portion is corroded. The probability of accidents increased.

또한 클램프에 의해 금속막대의 양단이 지지된 경우, 상판에 콘크리트를 타설하게 되면 금속막대를 포함한 클램프의 상부가 콘크리트에 매입되므로 응고후 분리하여 재활용할 수 없는 문제가 있었다.In addition, when both ends of the metal rod is supported by the clamp, when the concrete is placed on the top plate, the upper part of the clamp including the metal rod is embedded in the concrete, there is a problem that can not be separated and recycled after solidification.

상술한 문제를 해결하기 위한 본 발명의 목적은, 스틸박스의 양측을 손상시키지 않으며 콘크리트 타설 작업 후 간단히 분리하여 재활용할 수 있도록 한 상판 지지용 클램프구조를 제공하는데 있다.An object of the present invention for solving the above problems is to provide a clamp structure for supporting the top plate that can be easily separated and recycled after concrete pouring without damaging both sides of the steel box.

이와 같은 목적을 달성하기 위한 본 발명 상판 지지용 클램프구조는, 다수 배열구비된 지지대 양단을 교각 상부의 스틸박스 대응 양측에 결합시키기 위한 상판 지지용 클램프구조에 있어서, 양단 상면에 다수의 요철이 형성되고 단부에 각각 나사구멍이 형성된 지지대와; 스틸박스의 대응 상부에 지지되는 지지부와 지지대의 대응단부에 결합되는 고정부로 이루어지고, 고정부 저면에 지지대의 요철에 치합되도록 다수의 요철이 형성된 연결부재와; 연결부재의 지지부에 씌워지는 캡과; 연결부재의 고정부 및 지지대의 대응 단부에 체결되어 이들을 결합지지시키는 체결수단과; 지지대의 나사구멍에 체결되고 단부가 연결부재의 지지부에 지지되는 지지볼트로 이루어진 것을 특징으로 한다.Top plate support clamp structure of the present invention for achieving the above object, in the top plate support clamp structure for coupling both ends of the support provided with a plurality of arrangements on the steel box corresponding to the upper side of the piers, a plurality of irregularities are formed on the upper surface of both ends Supporters each having a screw hole at an end thereof; A connection member formed of a support coupled to the corresponding end of the support and a support supported on the corresponding upper portion of the steel box, and having a plurality of unevenness formed on the bottom of the fixed portion to be engaged with the unevenness of the support; A cap which is covered by a support of the connecting member; Fastening means fastened to the corresponding ends of the fixing portion and the support of the connecting member to support them; It is characterized in that the support bolt is fastened to the screw hole of the support and the end is supported on the support of the connecting member.

본 발명 상판 지지용 클램프구조의 한 특징은, 체결수단이, 양단이 수나사부가 형성된 U형볼트와, 양단에 관통구멍이 형성되어 U형볼트 양단에 결합되는 결합편과, 수나사부에 각각 체결되는 두 너트로 이루어진다.One feature of the clamp structure for supporting the upper plate of the present invention is that the fastening means is fastened to both ends of the U-shaped bolts having male threads, through-holes formed at both ends thereof, and coupled to both ends of the U-shaped bolts, respectively. It consists of two nuts.

따라서, 스틸박스에 관통구멍을 형성시키거나 금속막대를 용접시키지 않고도 이에 지지대를 고정결합시킬 수 있어, 이들의 결합에 의해 스틸박스의 일부가 손상되지 않으므로 결합상태를 더욱 견고하며, 안전사고를 방지시킬 수 있을 뿐 아니라, 연결부재의 지지부가 캡에 씌워진 후 스틸박스 상면에 지지되므로 콘크리트가 타설되어 응고되어도 캡만 콘크리트 내부에 매입될 뿐 연결부재는 간단히 분리되므로 콘크리트 타설후 해체작업이 매우 신속하고 편리한 이점이 있다.Therefore, the support can be fixedly coupled to the steel box without forming a through hole or welding a metal rod, and thus a part of the steel box is not damaged by the combination thereof. In addition, since the supporting part of the connecting member is covered on the cap and supported on the upper surface of the steel box, even if concrete is poured and solidified, only the cap is embedded in the concrete. There is an advantage.

본 발명의 구체적 특징 및 이점은 첨부된 도면을 참조한 이하의 설명으로 더욱 명확해 질 것이다.Specific features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

도1에서, 교각(1) 상부에는 그 길이방향을 따라 길게 스틸박스(2)가 설치되어 있고, 스틸박스(2) 상부에는 본 발명 클램프구조에 의해 장선(4)이 지지되어 있으며, 장선(4) 상에는 상판(5)이 위치된다.In FIG. 1, the steel box 2 is provided in the upper part of the pier 1 along the longitudinal direction, and the joist 4 is supported on the steel box 2 by the clamp structure of the present invention. 4) On the top plate 5 is located.

여기서 클램프구조는, 도2 및 도3에 도시한 바와 같이 장선(4)이 지지되도록 스틸박스(2) 사이에 등간격으로 다수 구비된 지지대(11)와, 지지대(11)와 스틸박스(2)를 연결하는 연결부재(14)와, 연결부재(14) 일단에 결합되는 캡(18)과, 연결부재(14)와 지지대(11)를 결합지지하는 체결수단(19)으로 이루어진다.Here, the clamp structure, as shown in Figures 2 and 3, the support 11 is provided with a plurality of equal intervals between the steel box 2 so that the joist 4 is supported, the support 11 and the steel box (2) ) Is composed of a connecting member 14 for connecting, a cap 18 coupled to one end of the connecting member 14, and a fastening means 19 for coupling and supporting the connecting member 14 and the support 11.

먼저 지지대(11)는 양측 단부 상면에 요철(12)이 형성되어 있고, 후술할 연결부재(14)가 이에 결합될시 지지부(15) 저면에 대향되도록 지지대(11) 양단에는 각각 나사구멍(13)이 형성되어 있다.First, the support 11 has irregularities 12 formed on upper surfaces of both ends, and when the connecting member 14 to be described later is coupled thereto, the screw holes 13 are formed at both ends of the support 11 so as to face the bottom surface of the support 15. ) Is formed.

이러한 지지대(11)는 스틸박스(2) 사이에 등간격을 갖도록 이격설치되어서 그 위에 장선(4)이 위치된다.The support 11 is spaced apart so as to have an equal interval between the steel box 2 so that the joist 4 is located thereon.

연결부재(14)는 중간부분이 절곡되어 있어 일측의 지지부(15)와 타측의 고정부(16) 사이에 높이차가 발생하고, 위치가 낮은 고정부(16) 저면에는 다수의 요철(17)이 형성되어 있어 지지대(11) 상의 요철(12)에 치합되며, 지지부(15)는 스틸박스(2)의 양측 결합부(3) 상에 위치된다.The connecting member 14 is bent in the middle part, so that a height difference occurs between the support part 15 on one side and the fixing part 16 on the other side, and a plurality of irregularities 17 are formed on the bottom of the fixing part 16 having a low position. It is formed to be engaged with the concavities and convexities 12 on the support 11, the support portion 15 is located on both sides of the engaging portion (3) of the steel box (2).

한편 연결부재(14)의 지지부(15)에는 캡(18)이 씌워져서 스틸박스(2) 상부에콘크리트가 타설된 후 응고되어도 연결부재(14)의 지지부(15)를 쉽게 분리할 수 있게 된다.On the other hand, the support part 15 of the connection member 14 is covered with a cap 18 so that the concrete can be poured into the upper portion of the steel box (2), and then the support part 15 of the connection member 14 can be easily separated. .

연결부재(14)의 고정부(16)와 지지대(11)의 대응 단부를 결합고정시키는 체결수단(19)은 양단에 수나사부(21)가 형성된 한쌍의 U형볼트(20)와, 양측에 관통구멍(23)이 형성되어서 U형볼트(20) 양단에 끼워지는 한쌍의 결합편(22)과, U형볼트(20)의 수나사부(21)에 체결되는 두 너트(24)로 이루어진다.The fastening means 19 for coupling and fixing the fixing end 16 of the connecting member 14 and the corresponding end of the support 11 is a pair of U-shaped bolts 20 having male threads 21 formed at both ends, and on both sides. The through-hole 23 is formed and consists of a pair of engaging pieces 22 fitted to both ends of the U-shaped bolt 20 and two nuts 24 fastened to the male screw portion 21 of the U-shaped bolt 20.

그리고 지지대(11)의 나사구멍(13)에는 지지볼트(25)가 체결되어서 지지볼트(25)의 단부가 지지부(15)의 저면을 눌러 지지시키므로 체결수단(19)의 체결력을 증대시키고 스틸박스(2)의 결합부(3)와 지지대(11)의 단부를 서로 지지시키게 된다.The support bolt 25 is fastened to the screw hole 13 of the support 11 so that the end of the support bolt 25 presses and supports the bottom of the support 15 so as to increase the fastening force of the fastening means 19 and to the steel box. The end of the coupling part 3 and the support stand 11 of (2) is mutually supported.

이러한 구성의 본 발명 상판 지지용 클램프구조는, 스틸박스(2)의 결합부(3)와 지지대(11)와의 결합이 연결부재(14)와 체결수단(19)에 의해 결합지지된다.In the clamp structure for supporting the upper plate of the present invention having such a configuration, the coupling between the coupling part 3 and the support 11 of the steel box 2 is supported by the coupling member 14 and the fastening means 19.

따라서, 스틸박스의 결합부에 관통구멍을 형성시키거나 금속막대를 용접시키지 않아도 되며, 이에 따라 관통구멍 또는 용접부위의 부식등의 이유로 인해 스틸박스(2)의 취약부인 결합부(3)가 더욱 취약해지는 종래 문제가 해결된다.Therefore, it is not necessary to form a through hole or weld a metal rod to the joining portion of the steel box, so that the joining portion 3, which is a weak part of the steel box 2, may be further damaged due to corrosion of the through hole or the welded portion. The conventional problem of weakening is solved.

한편 지지대(11)의 나사구멍(13)에는 지지볼트(25)가 체결되어서 그 단부가 결합부(3)의 저면을 밀고 있으므로, 스틸박스(2)의 결합부(3)와 지지대(11) 단부 사이에는 지지볼트(25)의 조임력에 의해 서로 미는 힘이 작용하게 되고, 이에 따라 결합부(3)에 작용하는 응력이 지지볼트(25) 및 지지대(11)의 양단으로 분산되며, 결국 스틸박스(2)의 취약부인 결합부(3)를 어느 정도 보호하게 된다.On the other hand, since the support bolt 25 is fastened to the screw hole 13 of the support 11 and the end thereof pushes the bottom surface of the engaging portion 3, the engaging portion 3 and the support 11 of the steel box 2 are supported. Between the ends, the pushing force of each other is acted by the tightening force of the support bolt 25, and thus the stress acting on the coupling part 3 is distributed to both ends of the support bolt 25 and the support 11, and eventually It protects the coupling part 3 which is a weak part of the box 2 to some extent.

이러한 상판 지지용 클램프구조는, 본 발명의 다른 특징인 캡(18)에 의해 다른 장점을 가지는 바, 캡(18)이 연결부재(14)의 지지부(15) 둘레를 감싸고 있으므로 콘크리트가 상판(5) 및 스틸박스(2)에 타설된 후 응고되어도 연결부재(14)가 간단히 분리된다.The clamp structure for supporting the upper plate has another advantage by the cap 18 which is another feature of the present invention, since the cap 18 is wrapped around the support 15 of the connecting member 14, the concrete is the upper plate 5. ) And the connection member 14 is easily separated even after being solidified after being poured into the steel box 2.

즉, 콘크리트가 완전히 응고된 후 본 발명 클램프구조를 분리할시 체결수단(19)을 풀고 연결부재(14)를 당기면 지지부(15)가 캡(18)에서 간단히 분리되므로 캡(18)을 제외한 나머지 부품들을 재활용할 수 있게 된다.In other words, when the clamp structure is released after the concrete is completely solidified, when the fastening means 19 are released and the connecting member 14 is pulled out, the support part 15 is simply separated from the cap 18. The parts can be recycled.

그러므로, 클램프구조를 해체시 콘크리트에 매입되었던 일부분을 절단하였던 종래와는 달리, 간단한 형상의 캡(18)만 연속 생산한다면 본 발명 클램프구조를 지속적으로 재활용할 수 있게 되므로 원가를 절감할 수 있게 된다.Therefore, unlike the prior art in which a part of the clamp structure is embedded in the concrete structure when the clamp structure is dismantled, if only the cap 18 of a simple shape is continuously produced, the clamp structure of the present invention can be continuously recycled, thereby reducing the cost. .

이상에서와 같은 본 발명에 따른 상판 지지용 클램프구조에 의하면, 스틸박스(2)에 관통구멍을 형성시키거나 금속막대를 용접시키지 않고도 이에 지지대(11)를 고정결합시킬 수 있어, 이들의 결합에 의해 스틸박스(2)의 일부가 손상되지 않으므로 결합상태를 더욱 견고하며, 안전사고를 방지시킬 수 있을 뿐 아니라, 연결부재(14)의 지지부(15)가 캡(18)에 씌워진 후 스틸박스(2) 상면에 지지되므로 콘크리트가 타설되어 응고되어도 캡(18)만 콘크리트 내부에 매입될 뿐 연결부재(14)는 간단히 분리되므로 콘크리트 타설후 해체작업이 매우 신속하고 편리한 이점이 있다.According to the clamp structure for supporting the upper plate according to the present invention as described above, the support 11 can be fixedly coupled thereto without forming a through hole in the steel box 2 or welding a metal rod. Since part of the steel box 2 is not damaged, the coupling state is more robust and not only prevents a safety accident, but also the steel box after the support part 15 of the connecting member 14 is covered with the cap 18. 2) Since it is supported on the upper surface, even if concrete is poured and solidified, only the cap 18 is embedded in the concrete, and the connection member 14 is simply separated, so that the dismantling work after the concrete is very quick and convenient.
