본 발명은 콘크리트 구조물의 보수 및 보강에 사용되는 모르타르 시공에서 일반적으로 타설 보수할 때 사용되는 장비로서 최근에는 압축공기로 분사시켜 도포하는 방법에서 일반 분사노즐로는 두껍게 시공할 수 없고 또 당일로 처리하지 못하고 시일을 소비하는 작업을 즉석에서 응고용 첨가제를 혼합하여 도포 두께도 높이고 응결도 빠르고 인력과 비용을 절감할 새로운 다기능 분사노즐에 관한 것이다.The present invention is a device generally used in the construction of the mortar used for the repair and reinforcement of concrete structures. Recently, in the method of spraying by applying compressed air, the general spray nozzle cannot be thickly applied and treated on the same day. It is a new multi-functional spray nozzle that can improve the coating thickness, congeal fast and reduce manpower and cost by mixing sealant additives on the fly.
이러한 다기능 분사노즐을 제작하는데 필요한 부분과 구성에서 압축공기 유입에 의한 와류발생 기능과 이로 인한 첨가제와 모르타르의 배합을 촉진시키며 합리적으로 분사까지 겸하게 하는 노즐몸체의 발명이다.It is an invention of a nozzle body that promotes the mixing of additives and mortar due to the vortex generation function due to the inflow of compressed air in the parts and configurations necessary for manufacturing such a multi-functional injection nozzle, and also to the rational injection.

본 발명이 있기 전 노즐은 단순한 노즐로서 별도로 연결되는 첨가제 투입구 및 압축공기분사 관이 없는 단순한 노즐인데 본 고안은 모르타르만 압축공기와 함께 분사시켜 손상된 콘크리트를 보수하면 오랫동안 붙어있지 않고 탈락되는 등의 불 합리로 인하여 재 보수하는 경우가 많았다.Before the present invention, the nozzle is a simple nozzle, which is a simple nozzle without an additive inlet and a compressed air injection pipe connected separately. Many repairs were made due to rationality.
그러나 본 고안은 모르타르의 품질을 향상시킬 수 있는 첨가제를 사전에 배합하여 활력이 저하되는 화학적 반응을 최소화하고자 분사 순간에 첨가할 수 있도록 별도로 분리시켜 보관하였다가 압축공기와 함께 순간배합이 되도록 노즐두부 내부에 회전 챔버를 통하여 와류현상으로 배합이 되도록 한 것이다.However, the present invention was previously formulated with additives that can improve the quality of mortar, and then stored separately to be added at the moment of injection in order to minimize chemical reactions that lower vitality. It is to be blended into the vortex through the rotating chamber inside.
첨가제와 모르타르를 함께 섞어 둔다면 화학변화를 일으키므로 분리 보관하였다가 노즐로 쏘는 순간 배합시키므로 분사 후 변화되도록 회전 챔버를 통하여 완전하게 배합되어 분사시키는 기술상의 방법과 특성을 이용한 것이다.If the additive and the mortar are mixed together, it causes chemical change, so it is separated and stored and mixed at the time of shooting with the nozzle. Therefore, the method and characteristics of the technology are used to spray and mix completely through the rotating chamber to change after the injection.
압축공기로 품어내는 숏크리트용 모르타르 노즐은 지금까지 도료용으로 사용될 뿐 모르타르와 같이 무거운 시멘트 혼합물에는 사용되지 못하였으나 최근 터널과 같이 협소한 장소와 인건비 절감 및 특수 모르타르가 개발되면서 서서히 여러 형태로 개발하여 사용되고 있으나 모르타르 무게로 인한 문제점을 연구 중에 있다.Mortar nozzles for shotcrete, which are compressed with compressed air, have been used only for paints, but have not been used for heavy cement mixtures such as mortars. It is being used, but the problem due to mortar weight is being studied.
본 발명의 노즐은 모르타르를 공급하는 큰 호스와 연결시키는 연결 관과 이에 연결되는 노즐몸체에 노즐두부 내부에 갖춘 챔버에서 발생되는 와류로 배합되게 한 다음 분사능력이 와류로 인하여 저하되지 않도록 강화시키기 위하여 별도의 분사노즐을 부착하여 압축공기만 발사되도록 장착시킨 것이 특징이다.The nozzle of the present invention is to be combined with the vortex generated in the chamber provided inside the nozzle head to the connecting pipe and the nozzle body connected to the large hose for supplying the mortar and then to enhance the spraying capacity not to be lowered by the vortex It is equipped with a separate injection nozzle so that only compressed air is fired.
또한 모르타르 원료인 시멘트와 첨가제와 모래 및 자갈 등에 물을 부어 배합을 한 모르타르에 부착력을 증가시키기 위해 유기물의 폴리머를 순간 배합시켜 탈락되는 현상을 배제시키는 장치와 공법이 가능하도록 한 장치인 것이다.In addition, to increase the adhesion to the mortar cement and additives and sand and gravel as a raw material of mortar to increase the adhesion to the mortar by mixing the polymer of the organic material to eliminate the phenomenon that the device and the method to be possible.
본 발명은 접착성을 갖는 모르타르(60)가 개발되면서 이에 상응하는 노즐을 개발하여 작은 공간에 간단한 공사를 수행하면서 연구 개발한 접착력을 강화 첨가제를 배합하여 사용하면 접착성이 약화되어 효과를 상실하는 점을 개선하기 위하여 분사출구(10) 뒤편에 와류를 발생시켜주는 첨가제 와류(72)를 일으켜주는 회전 챔버(22)를 원형으로 공간을 만들고 한 곳에 첨가제호스(70)를 통하여 주입되도록 첨가제 투입구(20)를 만들어 부착시키어 컴프레셔(80) 힘을 얻어내게 하였다.According to the present invention, when the
노즐모체(40)는 앞에 노즐두부(44)가 있고 한쪽은 첨가제 투입구(20)가 장착되고 다른 쪽은 회전챔버(22)로 들어오지 않고 분사출구(10)와 함께 같은 방향으로 분사되도록 하는 압축공기분사노즐(54)과 압축공기분사 관(52)이 장착되어 공기호스연결부위(50)로 역시 컴프레셔(80)에서 별도의 호스로 연결시킨다.The
노즐몸체(40) 뒤에는 노즐연결부위(42)가 형성되어 모르타르 호스에 끼워 어떠한 압력에도 빠지지 않게 하는 호스연결 관(30)이 끼워지도록 제작하여 관 연결부 위(34)와 결합되도록 요철(凹凸)형상으로 제작한다.A
이와 같이 제작되는 노즐의 이름을 압축공기로 뿜어내는 숏크리트용 모르타 르 노즐이라 명명하고 그 형태를 단면으로 보여 준다면 도 2와 같고 그 기능은 도 3과 같으며 노즐의 종류는 분사시키는 분사압축공기(82)의 각도에 따라 구분되는데 그 기준을 기울기 30도와 45도 및 60도로 구분하여 분사 후 응결시간을 확인한 바에 의하면 60도의 기울기에서 응결시간이 향상되었다.The name of the nozzle thus produced is called a shot mortar nozzle for blowing out compressed air, and the shape thereof is shown in cross section as shown in FIG. 2, and its function is the same as that of FIG. 3. According to the angle of (82), the standard was divided into 30 degrees, 45 degrees and 60 degrees of inclination. As a result of confirming the setting time after spraying, the setting time was improved at the inclination of 60 degrees.
이러한 결과는 실험실에서 믹서를 이용한 급결제를 모르타르(60)와 믹싱한 결과와 유사하였으며 노즐의 내부분사방식과 노즐의 각도가 현장에서도 동일하게 나타내고 있었는데 자료를 보면 다음과 같다.These results were similar to the results of mixing the mortar with a mixer in the laboratory with mortar (60), and the internal spraying method and the nozzle angle of the nozzle were represented in the field as well.
모르타르(60)는 죽과 같이 흐르도록 물을 첨가하여 믹서로 교반 수분함량을 일정하게 유지시켜 펌프 또는 고성능 컴프레셔(80)로 노즐몸체(40)를 거쳐 첨가제는 첨가제호스(70)로 투입되어 첨가제와류(72)에서 충분히 배합된 후 분사출구(10)로 토출되는 분출모르타르(62)는 60도 기울기로 분사되는 분사압출공기(82)로 인하여 강력하게 타설되므로 작업도 빠르고 타설 두께도 향상되며 골고루 완벽한 시공이 가능해 졌다.Mortar 60 adds water to flow like porridge to maintain a constant stirring water content with a mixer through the
본 노즐의 재질은 첨가제 및 모르타르의 알칼리성으로 인하여 부식이 일어나지 않도록 스테인레스나 부식성에 강한 소재로 제작하여야 오래 동안 사용이 가능하다.The material of this nozzle can be used for a long time when it is made of stainless or corrosive material so that corrosion does not occur due to alkali of additives and mortar.
분사 타설 두께를 측정한 결과 벽면에서는 1회 최고 타설 두께가 37센티미터까지 가능하였고 그 이상에서는 단면 탈락이 발생하였고 천장에 타설한 결과 1회 최대 두께는 32센티미터였으며 이 이상은 자중이 증가하여 탈락이 발생되었으나 이 정도로 단 1회에 시공이 가능해졌다.As a result of measuring the thickness of spraying, the maximum thickness of casting was possible up to 37 centimeters on the wall, and the dropping of the cross section occurred on the wall, and the maximum thickness was 32 centimeters on the ceiling. Although it occurred, it was possible to construct it in just one time.
또한 타설 후 재시공을 위한 작업시간이 종래에는 하루 2회를 시행할 수 없었으나 본 숏크리트용 모르타르 노즐이 개발되면서 시간대로 시공이 가능해져 당일로 작업을 종결할 수 있게 되었다.In addition, the work time for reconstruction after pouring could not be performed twice a day in the past, but as the shot mortar nozzle was developed, construction was possible in a time zone so that work could be terminated on the same day.
