이중단열재 및 메탈웨브를 이용한 벽체용 거푸집시스템의 구조내력평가 = Structural Bearing Capacity Evaluation of Wall Form System using Double Insulation Material and Metal Web

다국어 초록 (Multilingual Abstract)

In general, the form system as a temporary structure needs many workers and includes many dangerous factors during the installation and removal. Therefore, this study presents the permanent wall form system to provide the two functions of form and insulation, and to simplify the installation process without removal works. This wall form system consists of the double insulation materials and metal web for the security of safety, insulation and soundproofing. For the field application of this form system, the safety and serviceability of the form should be secured. To this end, this study first performs the tensile and shear experiments for the unit form system, and then evaluates the structural bearing capacity of the system through the concrete lateral pressure experiments considering various design variables.
The results of this study are as follows.
1) Through the tensile and shear strength tests, we can find that the safety of the unit form can be secured, based on concrete standard specification.
2) When the placement velocity is increased and installation intervals of supports are large, we can see that the deformation results of the lateral pressure experiment exceed the allowable deformation criterion. The above result analysis shows that the placement velocity and support installation interval should be considered in the design of form system.
3) The lateral pressures increase as the slump value and installation intervals of supports are large, and placement velocity is faster. Especially, the more deformation and lateral pressure are occurred in the part of concrete head.
