Description

Formwork for construction {MOLD FORM FOR CONSTRUCTION}

Embodiments disclosed herein relate to formwork for construction, which forms a formwork for curing concrete during the construction of a wall or slab of a building.

Reinforced concrete structure, which is usually applied in building construction, is a construction method with excellent formatability because it forms a structure by pouring liquid concrete into a formwork and hardening it.

Specifically, in the case of constructing structures such as slabs or walls of various buildings, a formwork of a certain area or a certain shape is made using a plurality of formwork forms, and then concrete is poured and cured on it or in the frame, It consists of the process of demolding the molds.

Here, the general formwork is basically in the form of a flat panel, and when forming various structures such as slabs, walls, beams, or load-bearing columns using concrete, it is formed into a plane by supporting the side of the concrete to be poured. is a support member.

These formworks were initially made of a wooden board (mainly plywood or plank) and each beam coupled to the rear side of the board to reinforce, and recently, metal formwork is mainly used.

A formwork made of a metal material in this way is called a euroform or a steel form, and among them, it is called an al-form made of an alloy aluminum material having strong structural strength.

Here, Alform is widely used because it is excellent in workability and robust, has good work efficiency, and is easy to reproduce.

However, the above Alform has the following problems.

First, Alform has a problem in that excessive noise is generated during the work process, resulting in excessive civil complaints.

Specifically, Alform has a problem in that, due to the nature of the metal material, when a pin is driven with a hammer in the process of connecting with other forms, or in the process of dismantling after pouring concrete, the hitting sound or falling noise by the hammer occurs excessively. There is a problem that the construction is stopped due to civil complaints caused by noise at the site.

Second, since Alform is made of a metal material, there is an environmental problem in that a release agent must be applied.

Specifically, since Alform is easily compatible with concrete due to the nature of its metal material, it is necessary to apply aluminum-only release agents to the molding surface as much as possible. Such aluminum-only release agents are toxic substances, so there is a risk of injury that causes flesh to become swollen when applied to the human body. In addition, there is a problem that it is difficult to work due to the occurrence of a severe odor.

In addition, when the aluminum-only release agent is buried on the reinforcing bars in the course of work, there is a problem in degrading the bond between the reinforcing bars and concrete.

Accordingly, in recent years, a form made of a synthetic resin material, such as a euro form type form using a synthetic resin plate and a frame disclosed in Utility Model Registration No. 20-0271524, has been released.
