Description

건축용 3D 프린터의 콘크리트 노즐 장치 및 이를 포함하는 건축용 3D 프린터Concrete nozzle device for building 3D printer and building 3D printer including the same
본 발명은 건축용 3D 프린터의 콘크리트 노즐 장치 및 이를 포함하는 건축용 3D 프린터에 관한 것으로, 더욱 상세하게는 건축용 3D 프린터에 사용되는 높은 점성 특성을 갖는 콘크리트 등의 재료가 원활하고 안정적으로 공급되도록 하여 작업성을 향상시키고, 작업 시간을 단축시키며, 노즐 장치 및 전체 3D 프린터의 고장을 방지할 수 있는 건축용 3D 프린터의 콘크리트 노즐 장치 및 이를 포함하는 건축용 3D 프린터에 관한 것이다.The present invention relates to a concrete nozzle device of a building 3D printer and a building 3D printer including the same, and more particularly, to work smoothly and stably to supply a material such as concrete having a high viscosity characteristics used in the building 3D printer The present invention relates to a concrete nozzle device for a building 3D printer and a building 3D printer including the same, which improves, shortens working time, and prevents failure of the nozzle device and the entire 3D printer.
일반적으로 철근콘크리트 구조물은 높은 압축강도를 가져 각종 건축물의 벽체, 슬라브 등의 구조물로 널리 시공되고 있다.In general, reinforced concrete structures have high compressive strength and are widely used as structures such as walls and slabs of various buildings.
이러한 철근콘크리트 구조물은 일반적으로 기초물 상에 철근을 배열하여 설치하고 상기 설치된 철근을 둘러싸는 거푸집(형틀)을 조성하여 그 사이에 콘크리트를 타설한 후 콘크리트가 양생되면 다시 형틀을 제거하는 공정을 거쳐 시공되었다.Such reinforced concrete structures are generally installed by arranging reinforcing bars on a foundation, forming a form (frame) surrounding the installed reinforcing bars, placing concrete therebetween, and then removing the form again when the concrete is cured. It was constructed.
그런데 이러한 종래의 철근콘크리트 구조물의 시공방법에 의하면, 거푸집을 설치해야만 하고, 콘크리트가 양생된 후에는 다시 거푸집을 일일이 해체해야 하기 때문에 공정의 수가 많고 복잡하여 작업이 번거롭고 작업공수가 늘어나게 하는 요인이 됨으로써 전체 건축공기를 지연시키는 문제점이 있었으며, 또한 거푸집은 항구적인 구성요소가 아니라 철거해야 하는 요소이므로 거푸집을 조성하고 해체하는 것은 필수적으로 물자와 건축비용의 낭비를 초래한다는 문제점이 있었다.However, according to the conventional construction method of reinforced concrete structures, since the formwork must be installed, and after the concrete is cured, the formwork must be dismantled one by one. There was a problem of delaying the overall construction air, and also because the formwork is not a permanent component but a component to be removed, there was a problem in that forming and dismantling the formwork essentially caused a waste of materials and construction costs.
한편, 최근에는 프린팅을 통해 3차원 형상의 제품을 성형하는 3D 프린팅 제조기술이 각광받고 있으며, 상기한 종래의 문제 해결을 위하여 3D 프린팅을 이용하여 콘크리트 구조물을 제조하려는 시도가 이루어지고 있다.Meanwhile, recently, 3D printing manufacturing technology for molding a 3D-shaped product through printing has been in the spotlight, and an attempt has been made to manufacture a concrete structure using 3D printing to solve the above-mentioned conventional problem.
일반적으로 알려진 콘크리트용 3D 프린팅 방법은 단순히 낮은 물-시멘트비(W/C)를 갖는 콘크리트 배합을 이용하여 적층성을 향상시키고자 하였으며, 이에 따라 비정형 형태의 콘크리트를 생산 및 자동화를 하려 했었으나, 콘크리트의 낮은 W/C 로 인해 콘크리트의 워커빌리티(Workability) 저하 및 콘크리트 압출성이 저하되는 문제점이 있었다.In general, 3D printing method for concrete is intended to improve lamination by simply using a concrete mixture having a low water-cement ratio (W / C). Accordingly, an attempt was made to produce and automate an amorphous concrete. Due to low W / C, there is a problem in that workability of concrete and workability of concrete are degraded.
이러한 문제점을 해결하기 위한 일환으로 시멘트 비율을 높일 수 있지만, 점도가 높은 시멘트의 물성으로 인해 노즐구로부터 원활하게 공급되지 못하며, 종국에는 노즐구가 폐색될 우려가 있었다.In order to solve this problem, the cement ratio can be increased, but due to the high physical properties of the cement, the cement nozzle cannot be smoothly supplied from the nozzle port.
또한, 상기한 문제점을 해결하기 위한 다른 일환으로 특허등록 제1526827호 "3Ｄ 프린팅 장치 및 이를 이용한 철골 콘크리트 구조물 시공방법"이 제안되어 있다. In addition, as another part to solve the above problems has been proposed Patent Registration No. 1526827 "3D printing apparatus and steel concrete structure construction method using the same" has been proposed.
상기 등록특허에서는 '베이스 프레임; 상기 베이스 프레임의 상부에 이동 가능 하게 설치되는 이동부; 상기 이동부의 일측에 설치되며 프린트 재료를 토출하는 압출헤드; 상기 이동부의 타측에 설치되며 분말 금속을 분사하는 분사노즐; 상기 압출헤드에 상기 프린트 재료로서 콘크리트 혼합물을 공급하는 제1 재료 공급부; 상기 분사노즐에 상기 분말 금속을 공급하는 제2 재료 공급부; 및 상기 압출헤드에 상기 프린트 재료로서 합성수지를 공급하는 제3 재료 공급부를 포함하는 3D 프린팅 장치'를 제안하고 있다. In the registered patent 'base frame; A moving unit installed to be movable above the base frame; An extrusion head installed at one side of the moving part and discharging a print material; An injection nozzle installed at the other side of the moving part and spraying powder metal; A first material supply unit supplying a concrete mixture as the print material to the extrusion head; A second material supply unit supplying the powder metal to the injection nozzle; And a third material supply unit for supplying a synthetic resin as the print material to the extrusion head.
그러나 상기 배경기술은 마이크로웨이브를 콘크리트에 조사하여, 콘크리트 내부의 물분자를 가열하고, 이에 따라 수화반응 및 경화를 촉진하여 3D 프린팅 콘크리트의 생산성, 적층성을 향상시키고자 하였으나, 마이크로웨이브로 인하여 콘크리트를 급속히 수화시키는 것에는 매우 높은 에너지의 마이크로웨이브가 필요하며, 마이크로웨이브의 에너지가 높아질수록 배합수의 손실이 커지고, 전체 장치가 복잡해지는 문제점이 있었다.However, the background art is to irradiate the microwave to the concrete, to heat the water molecules in the concrete, thereby promoting the hydration reaction and hardening to improve the productivity and lamination of the 3D printed concrete, but due to the microwave To hydrate rapidly requires a very high energy microwave, the higher the energy of the microwave, the greater the loss of the mixing water, there was a problem that the entire device is complicated.
따라서, 상기한 종래의 문제점을 해결하기 위한 본 발명은, 건축용 3D 프린터에 사용되는 높은 점성 특성을 갖는 콘크리트 등의 재료가 원활하고 안정적으로 공급되도록 하여 작업성을 향상시킬 수 있고, 작업 시간을 단축시킬 수 있어 경제성을 도모할 수 있는 건축용 3D 프린터의 콘크리트 노즐 장치 및 이를 포함하는 건축용 3D 프린터를 제공하는데 그 목적이 있다.Therefore, the present invention for solving the above-described conventional problems, it is possible to smoothly and stably supply materials such as concrete having a high viscosity characteristics used in the building 3D printer to improve workability, shorten the work time It is an object of the present invention to provide a concrete nozzle device of a building 3D printer and a building 3D printer including the same that can be made economical.
