CONSTITUTION: The fastening method of a reinforced earth block and a steel bar reinforcement comprises the steps of fitting a rubber plate(40), a pressure plate(30), a spring washer(20) and a nut to a steel bar reinforcement(50) in order, then fitting to a groove on a reinforced earth block(60) and filling up an empty space of the fitted part with non-shrink mortar.

Description

보강토 블록과 강봉보강재의 체결방법{omitted}Reinforcement method of reinforced earth block and steel reinforcement {omitted}

본발명은 보강토 블록과 보강재의 연결에 관한 것으로, 더욱 상세하게는 블록과 강봉보강재를 더욱 빨리 그리고 견고하게 일체화하는 방법에 관한것이다.The present invention relates to the connection of reinforcement earth block and reinforcement, and more particularly, to a method of integrating the block and rod reinforcement more quickly and firmly.

종래의 보강토옹벽과 강봉보강재와의 일체화 방법에는 ㄱ 자로 꺾은 강봉보강재를 보강토블럭위의 홈에 올려 놓는 방법이 있다.In the conventional method of integrating the reinforced soil retaining wall and the steel rod reinforcement, there is a method of placing the steel rod reinforcement bent by a letter in the groove on the reinforcement soil block.

ㄱ 자로 꺾어 위에 올려놓는 방법은 큰힘으로 강봉보강재를 인장시 강봉보강재가 뽑히는 위험이 있고, 인장력이 블록 상부분에 작용하므로 블록에 편심 모멘트가 발생된다. 그러므로 큰 인장력이 작용되는 상황에서는 적용이 어렵다.The method of placing the a-shape on the bar is a risk that the rod reinforcement is pulled out when the rod reinforcement is tensioned with great force, and the tension force acts on the upper part of the block, so that an eccentric moment is generated in the block. Therefore, it is difficult to apply in the situation where a large tensile force is applied.

상기와 같은 문제점을 해결하기 위한 것으로,To solve the above problems,

보강토 블록과 강봉보강재의 일체화에 있어서 외관상 아름답고, 시공성이 뛰어나며, 보강재 인장시 좀더 큰 인장력에 견딜수 있는 보강재와 보강토블럭의 연결법을 제공하는데 목적이 있다.In the integration of reinforcement earth block and steel reinforcement, the purpose is to provide a connection method of reinforcement and reinforcement toe block which is beautiful in appearance, excellent in workability, and able to withstand greater tensile strength when tensioning reinforcement.

상기한 목적을 당성하기 위한 본 발명은 보강토 블록과 강봉보강재와의 체결방법에 관한 것으로, 보강재를 거치시킬수 있는 블록과 보강재, 지압판, 고무판, 스프링와샤, 정착구로 구성되어 있다.The present invention for achieving the above object relates to a fastening method of the reinforcement earth block and the steel rod reinforcement, and consists of a block and reinforcement, a pressure plate, a rubber plate, a spring washer, anchorage can be mounted reinforcement.

지압판 설치시 고무판의 설치로 보강재 인장시 어느정도 유동성을 확보하였다. 또한 스프링와샤 설치로인하여 너트의 자연풀림을 방지하였다.When installing the pressure plate, the rubber plate was installed to secure some fluidity when tensioning the reinforcement. It also prevented natural loosening of nuts due to spring washer installation.

이하 본 발명에 의한 보강토옹벽과 강봉보강재의 체결을 첨부된 도면을 통해상세하게 설명하면 다음과 같다.Hereinafter, the fastening of the reinforced earth retaining wall and the steel rod reinforcing material according to the present invention will be described in detail with reference to the accompanying drawings.

도5는 본 발명에 의한 보강토블록과 강봉보강재의 체결부의 무수축몰탈처리후를 도시한 사시도이다.Figure 5 is a perspective view showing after the non-shrink mortar treatment of the fastening portion of the reinforced earth block and steel rod reinforcement according to the present invention.

도2, 도3, 도4, 도5에 도시된 바와 같이 본 발명은 강봉보강재에 고무판, 지압판, 스프링와샤, 너트를 차례대로 끼워 일체화 시킨후 블록위의 홈에 끼워 넣고, 끼워넣은 곳의 빈공간에 무수축 몰탈처리로 마무리된다.As shown in Figures 2, 3, 4, and 5, the present invention integrates a rubber plate, acupressure plate, a spring washer, and a nut in order to integrate the steel reinforcing material, and then inserts it into the groove on the block and inserts the bin into the groove. Finished with non-shrink mortar treatment in space.

상기와 같이 구성된 본 발명에 의한 보강토블럭과 강봉보강재 체결의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the reinforcement toe block and steel rod reinforcement fastening according to the present invention configured as described above are as follows.

고무판 및 스프링 와샤의 설치로 인하여 보강재 인장에 대하여 어느정도 블록의 유동성을 지닌다.Due to the installation of rubber plates and spring washers, the block has some fluidity with respect to the reinforcement tension.

보강재 설치위치가 블록의 중심이므로 보강재 인장시 블록에 편심모멘트가 발생하지 않는다.Since the reinforcement installation position is the center of the block, there is no eccentric moment in the block when the reinforcement is tensioned.

또한 체결위치가 블록의 내부에 있으므로 시공후 전면판이 외부로 노출되지않아 미관상 아름답다.In addition, since the fastening position is inside the block, it is beautiful in appearance because the front plate is not exposed to the outside after construction.

마지막으로 보강재 설치후 지압판 부분에 몰탈처리함으로써 시공후 지압판 및 체결부의 부식을 방지할수 있다.Finally, after installation of the reinforcement material, it is possible to prevent corrosion of the pressure plate and the fastening part by mortar treatment on the pressure plate part.

이하 본 발명에 의한 보강토블럭과 강봉보강재체결의 효과를 살펴보면 다음과 같다.Looking at the effects of reinforcement toe block and steel rod reinforcement according to the present invention as follows.

첫째, 강봉보강재의 인장력이 블록의 무게중심을 통과하므로 블록의 회전모멘트가 걸리지 않아 좀더 큰 인장력에 버틸수 있다.First, since the tensile force of the steel reinforcement passes through the center of gravity of the block, it does not take the rotation moment of the block and can withstand the higher tensile force.

둘째, 체결부가 외부로 노출되지 않아 블록설치시 외관이 아름답다.Secondly, the fastening part is not exposed to the outside, so the appearance is beautiful when the block is installed.

셋째, 체결부위가 몰탈처리되므로 시공후 체결부의 부식을 방지할수 있다.Third, since the fastening part is mortarized, it is possible to prevent corrosion of the fastening part after construction.
