본 발명은 보강성을 갖게한 빔 파이프(Beam Pipe)에 관 한것으로, 특히 수직및/혹은 수평방향으로 작용하는 하중에도 견디는 강도를 유지하는 보강막을 갖는 빔 파이프에 관한 것이다.FIELD OF THE INVENTION The present invention relates to beam pipes having reinforcement, and more particularly to beam pipes having a reinforcement film that maintains strength to withstand loads acting in the vertical and / or horizontal directions.

일반적으로 파이프는 그 특성상 액체와 기체를 운송하는 용도로는 많이 사용되고 있으나, 산업 혹은 건축,토목용(교량,철탑, 다리 등)으로는 하중에 약하다고 하는 이유로 인하여 전혀 사용되지 못하고 있고, 대부분 앵글이나 Ⅰ형 혹은 Ｈ형 빔들을 사용하고 있음은 주지된 사실이다.In general, pipes are used for transporting liquids and gases due to their characteristics, but they are not used at all for industrial or construction and civil engineering (bridges, steel towers, bridges, etc.) because of their weak loads. It is well known that Type I or H beams are used.

그러나 상기 빔 들은 수직방향으로부터 작용되는 물리적 혹은 기계적인 강도 등으로부터는 강한 내구성을 갖으나, 그 빔들에 대하여 수평 혹은 횡방향으로부터 작용되는 충격에는 다소 취약한 점이 있다고 하는 단점이 있다.However, although the beams have strong durability from physical or mechanical strength acting from the vertical direction, there is a disadvantage in that the beams are somewhat vulnerable to impact acting from the horizontal or transverse direction.

따라서 이들을 사용시 별도의 보강재를 사용하지 않으면 안되는 시공상의 불편과 경제적인 어려움이 있다.Therefore, there is an inconvenience in construction and economic difficulties that must use a separate reinforcement when using them.

따라서, 본 발명의 목적은 상기 제반 결점들을 해소하고, 양단이 개구된 중공상 관체의 내부에는 보강막을 일체로 형성한 것에의해, 수직(종) 혹은 수평(횡)방향으로부터 작용되는 물리적 혹은 기계적인 하중 혹은 압력에 견딜수 있는 강도를 갖게한 보강성을 갖게 한 빔 파이프를 제공하는데 있다.Accordingly, an object of the present invention is to solve the above-mentioned shortcomings, and to form a reinforcing film integrally inside the hollow tube having both ends open, so that the physical or mechanical acting from the vertical (vertical) or horizontal (lateral) direction is performed. It is to provide a beam pipe with reinforcement that has strength to withstand load or pressure.

상기 목적을 달성하기 위해 본 발명의 보강성을 갖게 한 빔 파이프는 청구항 1의 발명과 관련된 고온 가열한 재료를 강압하여 양단이 개구된 중공상을 이루게 형성한 관체; 및 상기 관체의 성형시 일체로 형성되면서 상기 관체의 내부를 길이 방향을 따라서 적어도 2개 이상의 공간으로 구획하는 보강막들을 포함하는 것을 특징으로한다.In order to achieve the above object, a beam pipe having reinforcement of the present invention comprises: a tubular body formed by forming a hollow shape with both ends open by pressing down the high temperature heated material according to the invention of claim 1; And reinforcement films which are integrally formed at the time of molding the pipe body and divide the inside of the pipe body into at least two spaces along a longitudinal direction.

또 청구항2기재의 보강성을 갖게 한 빔 파이프는 청구항 1에 있어서, 상기 관체는 원형이나 사각 단면을 이루게 형성됨을 특징으로 한다.In addition, the beam pipe having reinforcement of the base material of claim 2 is characterized in that the tubular body is formed to have a circular or rectangular cross section.

또한 청구항3 기재의 보강성을 갖게 한 빔 파이프는 청구항 1에 있어서,상기 관체의 보강막은 -, +, ＊ 모양으로 설치되어 상기 관체에 보강 특성을 갖게 한 것을 특징으로한다.Furthermore, the beam pipe which provided the reinforcement of Claim 3 is a reinforcement film of Claim 1 WHEREIN: The reinforcement film of the said tubular body is provided in-, +, * shape, It is characterized by having the reinforcing characteristic to the said tubular body.

도면부호(100)은 관 제조용 재료들을 넣는 수용실(102)가 형성된 콘테이너 로서, 상기 콘테이너(100)의 후측에는 상기 수용실(102)에 고온으로 가열하여 용융시키어 투입하는 재료(140)을 강압(强壓)하기 위한 가압 램(Ram)(110)이 이동가능하게 삽입되어 있고, 상기 콘테이너(100)의 앞쪽으로는 상기 가압 램(110)에 의해서 가압되는 재료(140)을 관체로 성형되게 하는 다이스(120)이 설치되어 있다.Reference numeral 100 is a container formed with a housing chamber 102 for the pipe material, the rear side of the container 100 is heated to a high temperature in the storage chamber 102 to melt the material 140 is injected A pressurizing ram 110 is inserted to move and the material 140 pressurized by the pressurizing ram 110 is formed in a tubular shape in front of the container 100. The die 120 is provided.

이러한 구성으로 상기 콘테이너(100)의 수용실(102)에 고온 가열한 재료를 넣은후, 램(110)으로서 가압하게 되면 재료(140)은 상기 램(110)의 압력에 의하여 상기 다이스(120)의 구멍(122)를 통하여 압출되면서 소정의 형상을 갖게되는 상기 실시예들과 같은 원형관체(12,12a~12c) 혹은 사각 관체들(22,22a)이 얻어지게 된다. 상기 관체들(12,12a~12c,22,22a)의 형상은 상기 다이스(120)의 구멍(122)의 형태에 따라서 임의로 변형 실시가 가능하다.In such a configuration, when the hot-heated material is put into the storage chamber 102 of the container 100 and pressurized as the ram 110, the material 140 is pressed by the pressure of the ram 110. Extruded through the hole 122 of the circular tube (12, 12a ~ 12c) or the square tube (22, 22a) as in the above embodiments having a predetermined shape is obtained. The shapes of the tubes 12, 12a to 12c, 22, and 22a may be arbitrarily modified according to the shape of the hole 122 of the die 120.

이상과 같이, 본 발명에 의하면, 양단이 개구된 중공상 관체의 내부에는 보강막을 일체로 형성한 것에의해, 수직(종) 혹은 수평(횡)방향으로부터 작용되는 물리적 혹은 기계적인 하중이나 압력에도 쉽게 절단되거나 휘어지는 일이 없는 강도를 갖는 효과가 있고, 이로 인하여 수평 혹은 수직 하중을 많이 받게되는 산업용, 건축 및 토목용의 빔으로도 안정적으로 할용할 수 있게되는 효과가 있다.As described above, according to the present invention, since the reinforcing film is integrally formed inside the hollow tube having both ends open, it is easy to be subjected to physical or mechanical load or pressure acting from the vertical (long) or horizontal (lateral) directions. There is an effect of having a strength that is not cut or bent, and thereby there is an effect that can be stably used as a beam for industrial, construction and civil engineering that is subjected to a large horizontal or vertical load.
