Description

일방향 볼트 조임용 너트 캡 어셈블리Nut cap assembly for one-way bolt tightening
본 발명은 볼트 조임시 너트캡 어셈블리를 미리 반대쪽에 부착하여 일방향 작업이 가능하도록 하고 구조물의 모듈간 체결 시 시공오차를 흡수하여 시공 시간을 단축하고, 작업자의 피로도를 줄일 수 있으며 현행 사용하는 일반 볼트 체결이 가능한 다양한 분야에 적용이 가능한 일방향 볼트 조임용 너트 캡 어셈블리에 관한 것이다. The present invention enables one-way operation by attaching the nut cap assembly to the opposite side in advance when tightening the bolt, and can reduce construction time by absorbing construction errors when fastening between modules of a structure, reduce operator fatigue, and use current general bolts It relates to a nut cap assembly for one-way bolt tightening that can be applied to various fields that can be fastened.
모듈러 공법(Modular Framing)은 공장에서 제작, 조립된 3차원적인 상자 형의 모듈러 유닛을 현장으로 운반하여 조립, 건설하는 방법으로 유닛부품에 들어가는 전기, 기계설비, 창호를 포함한 내외장재, 바닥재, 천장재, 화장실이나 부엌의 기기설치 등 주거공간의 90% 이상이 공장에서 완성된다. Modular Framing is a method of transporting, assembling, and constructing a three-dimensional box-shaped modular unit manufactured and assembled in a factory to the site. Electricity, mechanical equipment, interior and exterior materials including windows, flooring, ceiling materials, More than 90% of residential space, such as installation of toilets and kitchen equipment, is completed in factories.
공장 제작을 통해 일정 품질을 확보하고 현장으로 운반 조립하여 공기를 단축시켜 많은 고객에게 빠르게 공급할 수 있도록 시스템화 되어야 하며 이를 위해서는 현장에서는 최소한의 공정으로 단기간에 완성해 나갈 수 있도록 하는 기술이 필요하다.It should be systematized so that it can be supplied to many customers quickly by securing a certain quality through factory production, transporting and assembling to the site, and shortening the construction period.
모듈러 공법으로 제작되는 건축구조물은 공장에서 생산되는 유닛 모듈을 조합하는 기술에 따라 그 성능이 결정된다. 대부분의 모듈러 유닛을 이용하는 건축구조물은 현장 시공의 용이성 및 재사용 율 향상을 위하여 모듈러 유닛을 형성하는 수직부재들 수평부재들의 접합부 및 모듈러 유닛 간의 접합부를 볼트와 너트를 이용하는 체결로 결합하여 고정한다.The performance of the building structure manufactured by the modular method is determined by the technology of combining the unit modules produced in the factory. Most of the building structures using the modular unit are fixed by fastening the joints between the vertical members and horizontal members forming the modular unit and the joints between the modular units by fastening using bolts and nuts in order to improve the ease of on-site construction and the reuse rate.
모듈러의 큰 장점은 각각의 모듈이 공장에서 최대한 마감되어 현장에서 시공 기간을 단축시키는 것이다. 기존의 모듈러 접합부에서 볼트 접합할 경우 상부 모듈의 바닥 부와 하부 모듈의 천정부를 연결할 때 하부 모듈의 천정부 마감이 되지 않은 상태로 볼트와 너트를 체결하게 된다. The great advantage of modularity is that each module is finished at the factory as much as possible, shortening the construction period on site. In the case of bolting in the existing modular joint, when connecting the bottom of the upper module and the ceiling of the lower module, the bolts and nuts are fastened without finishing the ceiling of the lower module.
이 경우 접합부 체결 시 상부의 바닥에서 볼트를 삽입하고 하부모듈의 상부에서 너트를 조립하게 된다. 하부모듈의 너트 조립시 모듈러의 일부가 개방되어야 하므로 모듈러의 시공성이 떨어지게 되고 2명이 한조가 되어 시공하므로 조립의 효율성이 저하된다. 본 너트캡 어셈블리를 조립시 선시공하여 매립하여 두면 모듈러 조립시 상부모듈의 하부에서 일방향 조립이 되므로 1인작업이 가능하다. 모듈러 조립시 오차를 흡수할수 있는 허용치가 일반 볼트조립의 2mm허용값보다 큰 오차 허용치를 흡수하여 조립이 가능하다. In this case, when fastening the joint, the bolt is inserted from the bottom of the upper part and the nut is assembled from the upper part of the lower module. When assembling the nut of the lower module, a part of the module must be opened, so the workability of the modular is lowered and the efficiency of assembly is lowered because two people work in a team. If this nut cap assembly is pre-constructed and buried when assembling, one-man operation is possible because it is assembled in one direction from the lower part of the upper module during modular assembly. It is possible to assemble by absorbing the error tolerance that is larger than the allowable value of 2mm for general bolt assembly.
그리고, 모듈러 구조물은 각각의 모듈을 현장에서 조립하는 방식으로 약간의 오차에도 제대로 볼트 체결이 되지 않아 시공오차로 인해 공사 기간이 증가하는 문제가 발생한다. 또한, 체결과정에서 볼트와 너트의 나사산이 상하면서 제대로 된 체결이 이루어지지 않거나 추후 유지보수에서 문제가 생길 수 있다. In addition, the modular structure is a method of assembling each module on-site, and the bolts are not properly fastened even with a slight error, resulting in an increase in the construction period due to construction errors. In addition, as the screw threads of the bolt and nut are damaged during the fastening process, proper fastening may not be performed or a problem may occur in subsequent maintenance.
