Description

Permanent formwork with composite insulation {Mold assembly having compound insulator}

The present invention relates to a wall formwork that is easy to assemble using a composite insulating material and a T-shaped steel and secures insulation, and is installed through an assembly method of inserting a grooved composite insulating material between the T-shaped steel with the T-shaped steel as a vertical support. It relates to a permanent formwork using a simple composite insulation.

In general, a building structure is a composite functional structure that satisfies environmental performance, such as external insulation, and satisfies structural performance against external stress.

In most modern buildings, the construction process of a concrete structure is by installing a formwork, pouring concrete in it, forming the structure, and then dismantling the formwork. Subsequently, in order to satisfy the environmental performance of the building, a process such as construction of an insulating material and construction of a finishing material is performed.

Insulating material is used as a formwork as a plate-like material, and it is required to fix an insulating material by using a separate fastener or by drilling a hole to fix the insulating material to a wall surface. However, when installing fasteners between insulation materials or during drilling, defects in the insulation portion due to fasteners and perforated sections exposed to the outside air are generated.

Although a method of assembling in a block-type manner of inserting a groove for insulation is proposed, the strength of the insulation is weak, and it is not a form of an integrated concrete wall, but only a thin concrete support layer is produced.

The load generated during the pouring of concrete causes fluidity in the formwork due to the flow of unconsolidated concrete. Deformation and collapse of the formwork occurs due to the load caused by the concrete fluid, so it is important to secure mechanical performance in order to utilize it as a plate material for the formwork. The formwork support used for this has a problem of increasing the construction process such as constructing a separate support from the outside according to the load distribution of the concrete.

At this time, the composite insulating material 10 is made of a plate shape, may be made of two layers, and may be made of two layers of the phenolic foam 11 and styrofoam 12.

At this time, in the composite insulating material 10, styrofoam 12 is partially cut near the boundary between the phenolic foam 11 and styrofoam 12 to form an insertion groove 10a, and the insertion groove 10a The head portion of the T-shaped bar 20 is intended to be inserted.

At this time, the styrofoam 12 may be formed thicker than the phenolic foam 11 in the composite insulating material 10.

At this time, the composite insulating material 10 is formed in the form of a formwork wall by installing the T-shaped bar 20 in the form of a plurality of blocks in between.

The T-shaped bar 20, a part of the head portion is inserted into the insertion groove 10a formed on the side surface of the composite insulating material 10, and a part of the other head portion on the other side is inserted into the adjacent composite insulating material 10 It is inserted into the groove 10a, but is also inserted into the composite insulating material 10 on the opposite side so that the ends of the body face each other.

At this time, the insertion groove 10a into which the T-shaped bar 20 is inserted may be formed in the styrofoam 12.

At this time, the body of the T-shaped bar 20 is inserted so that the side surface of the composite insulation 10 is in close contact.

At this time, the head portions of the T-shaped bar 20 are respectively inserted into the insertion grooves 10a of the composite insulation 10 facing each other, and the side of the adjacent composite insulation 10 is in close contact with the body portion.

At this time, the fastening hole is formed in the T-shaped bar 20, and the fastening hole is formed at the end of the body of the T-shaped bar 20, and is formed at regular intervals along the longitudinal direction.

At this time, since the T-shaped bar 20 is inserted into the insertion groove 10a and is connected to the opposite T-shaped bar 20 by a formwork tie 30, the composite insulating materials 10 are coupled to each other and spaced It plays a role of keeping them.

1 to 5, the formwork tie 30 is equally spaced using a fastening hole formed in the body of the T-shaped bar 20 and a fastening hole formed in the body of the opposite T-shaped bar 20. It is a component that connects to each other to maintain.
