The present invention relates to a remode system for formwork and a construction method thereof, and in particular, the horizontal maintenance of the formwork, the assembly process of the formwork for implementing the wall, interlayer floor, etc. can be made more quickly, accurately and easily Of course, after the completion of the concrete pouring and curing step, can be applied directly to the concrete placing object to be built to significantly improve the efficiency of construction, formwork remodal system and the method for applying the formwork It is about.

As is well known, in order to build a building, concrete is poured most commonly, in order to maintain the shape of a building that is constructed through a curing step for a predetermined time.

The formwork is divided into various specifications according to the size of the building to be built, in order to firmly build the wall of the building vertically by using the formwork of the corresponding specification to the floor surface or slab (cured) surface cured with concrete The concrete must be poured while keeping it level.

However, the floor or slab surface that is cured with concrete is cured with a deviation of 1mm to 3mm without maintaining the horizontal state. When the floor height of a building is 2600mm, it is usually constructed by 150mm thickness of the slab. Even if the standard of 600 * 1200 is combined with two up and down to form the wall formwork, the height from the floor to the surface where the slab is formed is 2550mm, so a deviation of 50mm occurs when compared with the height of the building. For the deviation (50 ± 3mm), the horizontal and the height were conventionally adjusted using a horizontal wood and a thin plywood.

However, if the height of the formwork is adjusted and leveled by using horizontal wood and thin plywood as described above, the horizontal wood of thickness is equivalent to the thickness of the horizontal wood is uneven or the difference between the height of the floor and the height of the floor. In order to keep the horizontal neck horizontal or raise the horizontal neck by the height corresponding to the height difference of the height, the hassle and work of inserting thin plywood in two or several layers below the horizontal neck There was a difficulty. In addition, when the concrete is installed after the formwork is installed in the horizontal wood installed in the above manner, the concrete leaked into the gap caused by the thin plywood stuck under the horizontal wood, and the finishing condition was not good, so there was a problem that the separate finishing treatment had to be performed. .

In particular, the wood is warped when water is eaten, so when the concrete is poured, the horizontal wood and the plywood are warped due to the moisture generated from the concrete composition. There is a problem that the horizontal wood splits when you put or pull out, and also when the concrete is placed on the formwork, the concrete is attached to the horizontal wood so that it cannot be reused. Therefore, once used horizontal wood and thin plywood had to be disposed of, there was a problem such as causing environmental pollution due to mass production of building waste materials, there was a problem that the work cost is high due to the loss of materials.

As a conventional technique for solving the above problems, the "form horizontal adjustment mode" of the Republic of Korea Utility Model Publication "0326613" has been disclosed.
