Field of the Invention The present invention relates to a resin coating apparatus for a structural member, and more particularly, to a resin coating apparatus for a structural member that performs surface treatment for corrosion prevention of structural support members including reinforcing bars.

건축, 교량, 토목의 시공 과정에 소요되는 철근, 형강 등은 구조물의 내구성 증대와 수명 연장을 위하여 표면에 에폭시를 코팅하는 기술이 적용되고 있다. 이외에 구조물 지지용 부재의 연결에 사용되는 볼트 등의 소재도 에폭시 코팅을 적용하기도 한다.In the case of reinforced bar and section steel for building construction, bridges, and civil engineering works, epoxy coating technology is applied to increase the durability of structures and to prolong their life.

Spray, uniformly coated rock bolts are immersed in natural drying and cooling water, cooled to cure the epoxy, and then discharged. Accordingly, no contamination or corrosion occurs, and the effect of permanently maintaining the inherent property of the material is expected.

선행문헌 2는 철근의 표면을 쇼트볼에 의해 가공하는 가공부; 상기 철근이 히스테리시스 손실에 의해 표면온도가 증가되도록 하는 가열부; 상기 철근의 표면에 에폭시 수지를 피복하는 피복부; 및 상기 피복부의 외측에 형성되며, 상기 피복된 상기 철근을 냉각롤러와 냉각수로 냉각되도록 하는 냉각부;를 포함한다. 이에 따라, 가열시간을 단축하여 가열의 효율성을 향상시키고 에폭시 수지 피복의 품질을 향상시키는 효과를 기대한다.The prior art document 2 includes a machining part for machining the surface of the reinforcing bar by a shot ball; A heating unit for increasing the surface temperature of the reinforcing bar by hysteresis loss; A covering portion covering the surface of the reinforcing bars with an epoxy resin; And a cooling part formed on the outer side of the covering part to cool the coated reinforcing bar with a cooling roller and cooling water. As a result, it is expected that the heating time is shortened to improve the heating efficiency and improve the quality of the epoxy resin coating.

그러나, 상기한 선행특허에 의하면 비교적 대형의 구조물에 대한 표면처리를 연속된 일련의 공정으로 진행하기 미흡할뿐더러 코팅 완료후 벤딩과 같은 소성가공시 도막이 원형을 유지하기 곤란한 단점을 보인다.However, according to the above-mentioned prior art, it is not enough to proceed the surface treatment of a relatively large structure to a series of continuous processes, and it is difficult to maintain the original shape of the coating film during plastic working such as bending after completion of coating.

이하, 첨부된 도면에 의거하여 본 발명의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 구조물 부재를 대상물(10)로 하여 수지도료를 코팅하는 장치에 관하여 제안한다. 대상물(10)인 구조물 부재는 철근이나 볼트와 같은 비교적 소형의 부재 외에 H형강, I형강, C형강 등 상대적으로 대형의 부재를 포함하는 의미로 정의된다. 코팅용 수지도료는 친환경성이 높은 에폭시를 대상으로 하지만 반드시 이에 국한되는 것은 아니다. The present invention proposes an apparatus for coating a resin paint with a structure member as an object (10). The structural member as the object 10 is defined to include relatively large members such as H-shaped steel, I-shaped steel and C-shaped steel in addition to relatively small members such as steel bars and bolts. Resin coatings for coatings are intended for, but are not necessarily limited to, eco-friendly epoxies.

이때, 수지도료는 도료탱크(12)와 혼합기(15)를 사용하여 혼합된 상태로 공급한다. 일례로, 수지도료의 성분은 에폭시 수지 70~80wt%, 폴리부틸 아크릴산 10~15wt%, 트라이탄 수지와 폴리에스테르 수지의 혼합물 5~15wt%, 경화제 1~5wt%, 산화규소 1~5wt%, 첨가제 1~5wt%를 포함한다. 이에 따라 수지도료는 내식성, 내후성, 내습성, 내열성, 내한성, 난연성 외에 코팅후 벤딩 등의 후속가공을 위한 강도, 밀착성, 내마모성을 구비한다.At this time, the resin paint is supplied in a mixed state using the paint tank 12 and the mixer 15. For example, the components of the resin coating material may be selected from the group consisting of 70 to 80 wt% of an epoxy resin, 10 to 15 wt% of polybutylacrylic acid, 5 to 15 wt% of a mixture of a tributylstyrene resin and a polyester resin, 1 to 5 wt% of a curing agent, 1 to 5 wt% of an additive. Accordingly, the resin paint has strength, adhesion, and abrasion resistance for subsequent processing such as bending after coating in addition to corrosion resistance, weather resistance, moisture resistance, heat resistance, cold resistance and flame retardancy.

본 발명은 전처리수단, 가열기(35), 도포기(42), 냉각조(52) 등을 주요 수단으로 구비한다. 일련의 공정을 연속적으로 수행하도록 상기 주요 수단 사이에 대차(도시 생략)가 설치된다.The present invention comprises a pre-treatment means, a heater (35), an applicator (42), a cooling bath (52), etc. as main means. A bogie (not shown) is installed between the main means to continuously perform a series of processes.

본 발명에 따른 전처리수단은 상기 대상물(10)의 이물질을 제거하도록 설치된다. 전처리수단의 이물질 제거는 대상물(10)에 대한 수지도료의 밀착성을 높여 도막 형성의 불량을 방지한다. 이물질은 외부에서 부착되는 물질 외에 버어, 발청 등의 자체적 발생 물질도 포함한다. The pretreatment means according to the present invention is installed to remove foreign substances from the object 10. Removal of impurities from the preprocessing means increases the adhesion of the resin paint to the object 10, thereby preventing defective formation of the film. The foreign substance includes not only substances which are adhered from the outside, but also self-generated substances such as burrs and perspiration.

본 발명의 세부 구성에 의하면, 상기 전처리수단은 대상물(10)의 정지 또는 이동 상태에서 쇼트 블라스터(22), 브러쉬(26), 블로워(28)를 선택적으로 사용하는 것을 특징으로 한다. 쇼트 블라스터(22)는 대상물(10)의 이물질을 일차적으로 제거하는 동시에 표면조도를 향상한다. 대상물(10)로서 상대적으로 외형의 굴곡이 큰 형강류를 포함하므로 2종류의 쇼트, 예를 들어 40㎜ 및 0.5㎜를 혼합하여 사용하는 것이 좋다. 브러쉬(26)는 와이어 브러쉬 및 에어 브러쉬 혼용하는 것이 좋다. 블로워(28)는 보다 광범위하게 고압 공기를 분사하는 용도로 활용한다. 대상물(10)의 종류와 크기에 대응하여 쇼트 블라스터(22), 브러쉬(26), 블로워(28) 중에서 선택되는 조합으로 구성한다. 와이어브러쉬와 에어브러쉬는 쇼트 블라스트 과정에서 잔재하는 미세먼지를 제거한다.According to the detailed configuration of the present invention, the pretreatment means is characterized by using the shot blaster 22, the brush 26, and the blower 28 selectively in the state where the object 10 is stopped or moved. The shot blaster 22 primarily removes foreign substances from the object 10 and improves surface roughness. Since the object 10 includes a section having a relatively large curvature of contour, it is preferable to mix two types of shot, for example, 40 mm and 0.5 mm. The brushes 26 are preferably used in combination of wire brushes and air brushes. The blower 28 is used to spray the high-pressure air more extensively. A brush 26, and a blower 28 corresponding to the type and size of the object 10, as shown in FIG. Wire brushes and air brushes remove fine dust that remains in the shot blasting process.

이때, 전처리수단은 롤러 컨베이어(24) 상으로 대상물(10)을 이송하면서 작업을 진행한다. 롤러 컨베이어(24)는 대상물(10)과의 접촉면적을 최소화하면서 이송하는 것으로서 후속되는 공정에서 동일하게 적용할 수 있다.At this time, the pre-processing means advances the work while transferring the object 10 onto the roller conveyor 24. The roller conveyor 24 is conveyed while minimizing the contact area with the object 10, and the roller conveyor 24 can be equally applied to the following process.

또, 본 발명에 따르면 가열기(35)는 상기 대상물(10)의 표면온도를 설정범위로 유지하는 구조이다. 가열기(35)는 상류측으로 예열기(32)와 인접하게 연결되도록 설치된다. 대상물의 가열에 앞서서 예열을 수행하는 것이 계절에 관계없이 최상의 도막을 유지하는 측면에서 바람직하다. 예열기(32)와 가열기(35)는 신속한 가열을 위해 고주파 유도 방식의 히터를 사용한다. 다만 예열기(32)는 다수의 대상물(10)을 수용하는 공간을 확보하고 상대적으로 저렴한 연료를 사용하여 대상물을 서서히 승온시킬 수 있다. According to the present invention, the heater 35 has a structure that maintains the surface temperature of the object 10 at the set range. The heater 35 is installed so as to be adjacent to the preheater 32 on the upstream side. Preheating prior to heating of the object is preferable in terms of maintaining the best coating regardless of the season. The preheater 32 and the heater 35 use a high frequency induction heater for rapid heating. However, the preheater 32 can secure a space for accommodating a plurality of objects 10 and slowly raise the temperature of the object by using relatively inexpensive fuel.

또, 본 발명에 따르면 도포기(42)가 상기 가열된 대상물(10)의 표면에 대전된 수지도료를 도포하는 구조이다. 도포기(42)는 도료탱크(12)와 인접하게 연결되도록 설치된다. 이는 대상물(10)을 접지하고 음 대전성 또는 양 대전성 수지도료를 분사하는 과정이며, 대전된 전하가 0.6㎃ 이상을 유지하도록 미립자 물질과 전하 조절제를 혼합할 수도 있다.According to the present invention, the applicator (42) applies a resin coating material charged on the surface of the heated object (10). The applicator 42 is installed so as to be adjacent to the painting tank 12. This is a process in which the object 10 is grounded and a negatively chargeable or positive chargeable resin paint is sprayed, and the particulate material and the charge control agent may be mixed so that the charged charge is maintained at 0.6 mA or more.

본 발명의 세부 구성에 의하면, 상기 도포기(42)는 자세변동 가능한 구조를 지닌 다수의 분사노즐(43)로 대상물(10)의 표면에 전체적으로 수지도료를 분사하는 것을 특징으로 한다. 도포기(42)는 대상물(10)을 밀폐된 상태로 수용할 수 있는 챔버로 구성된다. 분사노즐(43)은 도포기(42)의 상하좌우 6면에 모두 설치하여 대상물(10)을 전체적으로 코팅한다. 대상물(10)이 형태가 변동되는 상황을 감안하여 분사노즐(43)의 적어도 일부는 자세변동이 가능하도록 구성한다. 분사노즐(43)의 자세변동은 전후진, 승하강, 회전 등을 포함하는 의미로 정의된다.According to the detailed configuration of the present invention, the applicator (42) is characterized in that the resin paint is sprayed as a whole on the surface of the object (10) by a plurality of injection nozzles (43) having a posture changeable structure. The applicator 42 is constituted by a chamber capable of receiving the object 10 in a sealed state. The spray nozzles 43 are all provided on the upper, lower, left, and right sides of the applicator 42 to coat the object 10 as a whole. At least a part of the injection nozzle 43 is configured to be capable of attitude change in consideration of a situation in which the shape of the object 10 varies. The attitude change of the injection nozzle 43 is defined as meaning including forward / backward, upward / downward, rotation, and the like.

이때, 상기 분사노즐(43)은 180˚ 이상의 범위로 분사 가능한 구형헤드(44) 상에 수지도료의 이온화를 위한 이온형성코일(46)을 구비하는 것을 특징으로 한다. 구형헤드(44)는 구체 상에 다수의 노즐을 구비하는 형태로서 도 2의 H형강과 같이 굴곡이 많은 경우 효과적인 도포가 가능하다. 이온형성코일(46)은 구형헤드(44)의 유로상에 설치되어 분체에 음이온성 또는 양이온성을 부여한다. 이온형성코일(46)은 외부의 교류전원(도시 생략)과 연결되는 방습형 단자를 구비한다.At this time, the injection nozzle 43 is provided with an ion forming coil 46 for ionizing the resin paint on the spherical head 44 which can be sprayed in a range of 180 degrees or more. The spherical head 44 has a plurality of nozzles on a sphere and can be effectively applied when the curvature is large like the H-beam in Fig. The ion forming coil 46 is provided on the flow path of the spherical head 44 to impart anionic or cationic properties to the powder. The ion forming coil 46 has a moisture-proof terminal connected to an external AC power source (not shown).

한편, 본 발명에 의한 코팅의 일례로 분사노즐(43)의 공기압은 1.5~3㎏/㎠ 로 유지하고 55~65㎸의 전압을 인가한 상태로 분체상의 수지도료를 대상물(10)에 골고루 분사하여 용융시킨다. On the other hand, as an example of the coating according to the present invention, the air pressure of the spray nozzle 43 is maintained at 1.5 to 3 kg / cm 2, and the powdery resin paint is uniformly sprayed onto the object 10 And then melted.
