Description

스폿용접에 의해 결합구가 접합된 난간두겁대{Handrail coupled coupling by spot-welding}Handrail coupled coupling by spot-welding}

본 고안은 스폿용접에 의해 결합구가 접합된 난간두겁대에 관한 것으로, 더욱 상세하게는 기계적 방법으로 용이하게 접합가능하고 접합부위의 말끔한 처리를 유도할 수 있는 스폿용접에 의해 결합구가 접합된 난간두겁대에 관한 것이다.The present invention relates to a handrail thickened to which a coupler is joined by spot welding, and more particularly, to which a coupler is joined by spot welding, which can be easily bonded by a mechanical method and induces a neat treatment of the joint. It's about a railing belt.

난간은 계단이나 다리 등의 가장자리에 세워 낙상(落傷)을 막으면서 장식의 구실도 하도록 설치되는 시설물이다. 통상 난간은 손잡이에 해당하는 난간두겁대와 이를 지지하는 난간기둥 및 난간을 바닥에 고정시키기 위한 고정브라켓으로 구성된다.A railing is a facility that stands on the edge of a staircase or a bridge and serves as a decoration while preventing falls. A railing is usually composed of a railing girder corresponding to the handle, a railing pillar supporting the railing, and a fixing bracket for fixing the railing to the floor.

종래에는 난간을 구성하는 난간두겁대, 난간기둥 및 고정브라켓이 세 부재가 일체로 제작되거나 또는 난간두겁대 및 난간기둥 두 부재가 일체로 제작되는 것이 일반적이었다. 이와 같은 난간의 경우 그 부재중 일부가 파손되면 전체의 교체가 불가피하였는 바, 난간 전체의 교체공사가 복잡해지는 한편 공사비 및 자재비가 상당히 부담되었고 나아가 폐자재를 양산시키는 문제를 초래하였다. 이에, 이를 개선하고자 최근에는 각 부재를 조립식으로 결속하여 설치가능한 조립식 난간이 개발되고 있다.Conventionally, the railing girder, the railing pillar and the fixing bracket constituting the railing were generally made of three members integrally, or two members of the railing girder and railing pillars were made integrally. In the case of such handrails, when some of the members were damaged, the replacement of the entire railing was inevitable. As a result, the replacement work of the entire railing was complicated, and the construction and material costs were considerably burdened, further causing the problem of mass-producing waste materials. Accordingly, in order to improve this, in recent years, prefabricated handrails that can be installed by binding each member in a prefabricated manner have been developed.

도 1은 통상의 조립식 난간에서 난간기둥과 난간두겁대의 조립이 가능하도록 난간두겁대에 난간기둥 결속을 위한 결합구가 접합된 상태를 도시한 도면이다. 즉, 난간기둥을 난간두겁대에 접합된 결합구에 끼움 결속함으로써 난간기둥과 난간두겁대를 조립식으로 설치하는 것을 가능케 한 것이다. 도 1에서와 같이 조립식 난간을 위한 난간두겁대에는 통상 한쌍의 수직부재가 소정의 틈(난간기둥의 수용이 가능한 정도)을 두고 이격하여 배치되는 결합구가 아크용접에 의해 접합된다. 이때, 아크용접에 의한 접합면적의 확보를 위해 결합구의 단부는 절곡된 접합단부로로 구성된다. 1 is a view showing a state in which a coupler for joining a handrail pillar is joined to a handrail girder so that the handrail pillar and the handrail girder can be assembled in a conventional prefabricated handrail. In other words, it is possible to install the handrail pillar and handrail thickening prefabricated by binding the handrail to the coupling unit joined to the handrail. As shown in Fig. 1, a coupler of vertical handrails for a prefabricated handrail is normally joined by arc welding, where a pair of vertical members are spaced apart from each other with a predetermined gap (to allow accommodating handrail posts). At this time, in order to secure the joint area by arc welding, the end of the coupler is composed of bent joint ends.

그러나, 종래의 결합구가 아크용접에 의해 접합되는 난간두겁대는 접합부위의 처리가 말끔하지 못하다는 문제와 일일이 수작업으로 용접해야 한다는 작업상 번거로움이 있었으며, 또한 직접적으로 열을 가하여 용접봉을 녹이면서 용접이 이루어지기 때문에 난간두겁대와 결합구의 물성변화에 따른 내구성 저하와 미관 저해가 우려되었으며, 나아가 난간기둥이 수용되는 결합구의 틈을 일정하게 형성시키는데 어려움이 있었다.However, the handrail thicker in which the conventional coupler is joined by arc welding has a problem in that the processing of the joint is not neat and has to be worked manually, and it is necessary to weld it manually by hand. Because welding is performed, durability deterioration and aesthetics deterioration due to the change of physical properties of the railing girder and the fitting are feared, and furthermore, there is a difficulty in forming the gap of the fitting to accommodate the railing pillar.

본 고안은 상기한 문제를 개선하고자 안출된 것으로서, 기계적 방법으로 용이하게 접합가능하고 접합부위의 말끔한 처리를 유도할 수 있도록 한 스폿용접에 의해 결합구가 접합된 난간두겁대를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and the object of the present invention is to provide a balustrade belt in which a coupler is joined by spot welding, which can be easily bonded by a mechanical method and induces a neat treatment of the joint. have.

본 고안의 다른 목적은 스폿용접에 의해 접합가능하도록 말굽형으로 제작된 결합구를 접합한 난간두겁대를 제공하는 것이다.It is another object of the present invention to provide a handrail thicker bonded to a coupler made of horseshoe to be joined by spot welding.

상기한 목적달성을 위해 본 고안은The present invention for achieving the above object

바(bar)형의 난간두겁대; 및, 상기 난간두겁대를 지지하는 난간기둥과 결속하는 부재로서, 상기 난간두겁대에 길이방향으로 소정 간격으로 배치 접합되는 복수개의 결합구;를 포함하여 구성되며,Bar-shaped balustrades; And a plurality of couplers that are joined to the railing pillar supporting the balustrade girder, the plurality of couplers being disposed at predetermined intervals in the longitudinal direction to the balustrade girder.

상기 결합구는 양 수직부와 양 수직부 일단을 서로 잇는 수평부로 구분되는 말굽(∩)형 부재로, 상기 수평부가 상기 난간두겁대에 맞닿도록 하여 스폿용접에 의해 접합되는 것임을 특징으로 하는 스폿용접에 의해 결합구가 접합된 난간두겁대를 제공한다.The coupler is a horseshoe-shaped member which is divided into horizontal portions connecting both vertical portions and both vertical portions, and the horizontal portions are joined by spot welding so that the horizontal portions abut against the railing girder. Thereby providing a handrail mat to which the coupler is joined.

이하, 첨부한 도면 및 바람직한 실시예에 따라 본 고안을 상세히 설명한다.Hereinafter, the present invention according to the accompanying drawings and preferred embodiments will be described in detail.

도 2는 본 고안에 따른 스폿용접에 의해 결합구가 접합된 난간두겁대의 사시도이고, 도 3은 도 2의 제작모습을 보여주는 도면이며, 도 4는 도 2에서 난간두겁대와 결합구가 분리된 상태의 단면도로서, 도시하고 있는 바와 같이 본 고안은 복수개의 말굽(∩)형의 결합구(20)가 난간두겁대(10)에 스폿용접(점용접, spot welding)에 의해 접합된다는 특징이 있다.Figure 2 is a perspective view of the handrail joint bonded to the coupler by spot welding according to the present invention, Figure 3 is a view showing the production of Figure 2, Figure 4 is a handrail from the coupler is separated from the coupler As a cross-sectional view of the state, the present invention is characterized in that a plurality of horseshoe-shaped couplers 20 are joined by spot welding (spot welding) to the handrail thickener 10. .

스폿용접은 압접시 접합재와 피접합재가 마주치는 반대면에서 서로 반대방향으로 +,-전극을 대고 누르면서 전기를 통하는 방법으로, 누르는 힘이 상쇄되어 비비틀림 변형이 생기지 않게 하기 때문에 동일면에서 같은 방향으로 진행되는 아크용접에 비하여 접합부위의 내력을 손상시키지 않는다는 점에서 유리하다. 또한, 스폿용접은 스폿용접기에 의한 기계적인 작업으로 이루어지기 때문에 작업의 편리성이 있으며 압접에 의한 방법이므로 스폿용접한 부위를 깔끔하게 처리할 수 있는 반면, 아크용접은 작업자의 수작업에 의존하므로 작업상 번거로움이 있으며 용접봉을 녹이면서 접합하는 방법이므로 아크용접한 부위를 뭉그러뜨리거나 지저분하게 하는 경향이 있는 바, 이러한 점을 고려할 때에도 스폿용접은 상당히 유리한 방식이다. 본 고안에서는 이와 같은 스폿용접을 난간두겁대와 결합구의 접합에 적용하고 있는 것이다.Spot welding is a method of passing electricity while pressing the + and-electrodes in opposite directions on the opposite side where the bonding material and the material to be joined face each other during press welding, and the pressing force is canceled so that there is no torsional deformation. It is advantageous in that it does not impair the strength of the joints as compared with the arc welding in progress. In addition, since spot welding is made by mechanical work by spot welding machine, it is convenient to work and it is a method of pressure welding, so spot welding part can be neatly processed, whereas arc welding depends on manual operation of worker. Since it is a hassle and a method of melting and welding the welding rod, there is a tendency to crush or mess up the arc welded part. In view of this, spot welding is a very advantageous method. In the present invention, such spot welding is applied to the joining of the railing girder and the coupler.

스폿용접을 위해 본 고안에서는 결합구(20)를 도 2 내지 도 4에서 도시하고 있는 바와 같이 말굽(∩)형으로 구성하고 있다. 즉, 결합구(20)를 양 수직부(21)와 양 수직부(21) 일단을 서로 잇는 수평부(22)로 구분되는 말굽(∩)형으로 구성하여, 상기 수평부(22)가 난간두겁대(10)에 맞닿도록 함으로써 한 번의 스폿용접에 의해 접합되도록 하는 것이다. 이렇게 접합된 말굽형 결합구의 양 수직부(21) 사이에는 난간두겁대(10)를 지지하기 위한 난간기둥(30)이 끼워지게 된다. In the present invention for spot welding, the coupler 20 is configured as a horseshoe type as shown in FIGS. That is, the coupler 20 is configured in a horseshoe shape divided into two vertical portions 21 and horizontal portions 22 connecting one end of both vertical portions 21 to each other, so that the horizontal portions 22 are railings. It is to be joined by one spot welding by making contact with the girth 10. FIG. The handrail pillar 30 for supporting the handrail thickener 10 is inserted between the two vertical portions 21 of the horseshoe type coupling tool joined in this way.

도 3에서는 스폿용접기에 의해 난간두겁대(10)에 결합구(20)를 접합하는 과정을 도시하고 있는데, 그 과정은 스폿용접기의 작업대에 난간두겁대(10)를 올려놓은 후 결합구의 수평부(22)를 난간두겁대에 맞닿도록 배치하고 이어 결합구의 수직부(21) 끝단을 누르면서 난간두겁대(10) 아래와 결합구의 수직부(21) 위에서 반대방향의 전극을 가하여 압접하는 방법으로 진행된다. 이때, 도 2 내지 도 4에서와 같이 말굽형의 결합구(20)로 그 수평부(22)에 접합볼(22a) 복수개가 돌출 형성된 것을 채택하면, 상기 접합볼(22a)이 난간두겁대(10)와 맞닿도록 배치하여 스폿용접할 때 가압에 의한 전기저항열이 접합볼(22a)에 집중하게 되므로 접합볼이 형성되지 않아 수평부 전체를 통해 접합되는 경우보다 더욱 안정적이면서 효율적인 접합이 가능하게 된다. 3 shows the process of joining the coupler 20 to the handrail thickener 10 by a spot welder, the process of placing the handrail thickener 10 on the workbench of the spot welder horizontal part of the coupler (22) is placed in contact with the railing girder and then press the end of the vertical portion 21 of the coupler while pressing the electrode in the opposite direction on the vertical portion 21 of the coupler and below the handrail thickening. . At this time, as shown in Figures 2 to 4 when the horseshoe-shaped coupling sphere 20 adopts that the plurality of jointing ball 22a protruding in the horizontal portion 22, the jointing ball 22a is a balustrade thick ( 10) Since the electric resistance heat due to the pressurization is concentrated in the joint ball 22a when the spot is welded by contact with the spot, the joint ball is not formed and thus more stable and efficient joining is possible than the case where the joint ball is joined through the entire horizontal part. do.

본 고안에서의 난간두겁대(10)는 도 2 내지 도 4에서 도시하고 있는 바와 같이 결합구(20)와의 접합부분이 오목하게 내들어가도록 형성된 것을 채택함이 바람직하다. 이는 본 고안에 따른 결합구(20)가 접합된 난간구겁대(10)가 조립식으로 난간기둥(30) 위에 설치되는 경우 난간두겁대(10)와 결합구(20)와의 접합부분이 외부에서 잘 보이지 않도록 하여 말끔한 외관을 확보하기 위함이다. 특히, 접합볼(22a)이 형성된 결합구(20)를 접합하는 경우에는 접합볼(22a)과 접합볼(22a) 사이의 틈새가 보여지는 것을 차단하기 때문에 더욱 바람직하게 될 것이다.Handrail thickener 10 in the present invention is preferably adopted to be formed so as to concave the joining portion with the coupler 20, as shown in Figures 2 to 4. This means that when the handrail cob 10 to which the coupler 20 is bonded according to the present invention is prefabricated on the handrail pillar 30, the joint part of the handrail coarse 10 and the coupler 20 is easily seen from the outside. This is to secure a neat appearance. In particular, in the case of joining the coupler 20 formed with the joint ball 22a, it will be more preferable because the gap between the joint ball 22a and the joint ball 22a is blocked.

도 5는 도 2의 스폿용접에 의해 결합구(20)가 접합된 난간두겁대(10)를 사용한 조립식 난간을 도시한 도면으로, 본 고안에 따른 말굽(∩)형의 결합구(20)가 접합된 난간두겁대(10)가 수직으로 설치된 난간기둥(30)에 조립식으로 끼움 결합하는 것을 보여주고 있다. 즉, 난간두겁대(10)에 접합된 말굽형의 결합구(20) 내에 난간기둥(30)이 끼워지도록 한 후 고정설치하여 난간을 완성하고 있는 것이다. 고정설치는 도시하고 있는 바와 같이 결합구의 양 수직부(21)와 난간기둥(30)의 동일한 위치에 볼트구멍(21a)을 형성시키고 볼트(31)를 삽입 너트(32)를 체결하는 방식으로 이루어지고 있으나, 다른 방법을 채택하는 것도 가능하다.FIG. 5 is a view illustrating a prefabricated handrail using a handrail thickener 10 in which a coupler 20 is joined by spot welding of FIG. 2, and a horseshoe-shaped coupler 20 according to the present invention is shown. Bonded handrails are shown to be assembled by fitting a handrail to the railing column (30) installed vertically. In other words, the handrail pillar 30 is fitted into the horseshoe-shaped coupler 20 joined to the handrail thickener 10 to fix the railing. As shown in the drawing, the bolt holes 21a are formed at the same positions of both vertical portions 21 and the handrail pillars 30 of the coupler, and the bolts 31 are fastened to the insertion nuts 32. However, it is possible to adopt other methods.

이상과 같은 본 고안에 따르면, 난간두겁대와 결합구를 스폿용접에 의해 접합함으로써 기계에 의한 접합이 용이하게 이루어져 작업상 편의를 도모할 수 있게 되며, 나아가 접합부위의 말끔한 처리를 유도할 수 있게 되어 미려한 외관을 확보할 수 있는 효과가 기대된다. 또한, 말굽형으로 제작된 결합구를 난간두겁대에 접합하고 있는 바, 1회의 작업으로 결합구의 접합이 가능하게 되어 작업효율의 향상을 기대할 수 있다.According to the present invention as described above, by joining the handrail and the coupler by spot welding, the joining by the machine is easy to facilitate the operation convenience, furthermore to induce a neat treatment of the joining site Therefore, the effect that can secure a beautiful appearance is expected.
