UPSIDE SLIP FORM FOR LARGE SECTION REPAIR AND REHABILITATION OF UNDERSIDE OF CONCRETE STRUCTURE

摘要

The present invention produces a formwork used for the enlargement or restoration of large sections of the lower part for repair and structural reinforcement of marine structures or concrete structures by applying upward upward artificial pressing to increase the sealing effect of sectional restoration materials. In addition, the purpose of the present invention is to provide an effect of increasing the structural suitability behavior through the integration of new and old concrete by increasing the adhesion between the existing concrete surface and the new section restoration material.;To this end, the upwardly moveable steel formwork structure of the present invention uses a metal bottom plate formwork and an angle to support the bottom plate when the cross section recovery and expansion of the lower part of the concrete structure using the mortar and the polymer mortar by using a bolt and nut Rotating the nut after filling provides an open upward movable steel formwork for pressing the bottom plate formwork upward.;According to the present invention, when the large section of the lower part of the concrete structure is repaired or the section is expanded, it prevents the downward deflection due to the self-weight of the mortar, prevents the interface peeling with the existing concrete due to the dry shrinkage, and prevents deformation by tightening the formwork to prevent deformation Increasing the properties has the effect of providing a structure that can structurally behave synthetically.
