Description

Modular formwork apparatus

The present invention relates to a technology related to a formwork capable of accommodating mortar, and more particularly, to a modular formwork device.

Various concrete structures, including precast concrete conduits used for pits and sewage pipes, deteriorate over time due to quality problems of the used concrete, negligent management, mechanical, physical, and chemical actions, and the influence of the surrounding environment. lifespan is shortened rapidly.

According to the deterioration phenomenon of concrete, cracks occur in the concrete structure, and the generated cracks penetrate from the surface side of the concrete structure to the inside to promote peeling and dropping of concrete, which in turn leads to a reduction in the cross section of the concrete structure lower the load-bearing capacity.

Concrete structures whose structural stability is weakened due to a decrease in load-bearing capacity are repaired and reinforced in order to extend their service life.

What is needed for this is to reinforce a concrete structure by filling it with mortar, or a formwork device for forming a new structure is required. However, the conventional formwork device has different sizes and shapes, so it is not modularized, and the support means or coupling means for combining and using such a formwork device are not modularized, so there is an inconvenience in using the formwork device.
