The present invention relates to a mold spacing holder that maintains the spacing of the formwork in installing the formwork, and more particularly, by providing a bracket with magnetic material on the inside, the operator simply supports the upper support at an angle of 90 °. The one-way rotation allows the spacer to be easily detached from the formwork, thereby improving workability of formwork, and further providing a packing inside the spring-inserted housing to prevent the component from corroding due to moisture. It relates to a mold spacing zone for long-term use.

In general, when a building is constructed, reinforcing bars are formed to form a skeleton, and formwork is installed on the inner and outer sides of the skeleton, and then concrete is cast between the inner and outer molds to cure for a certain period of time. At this time, the conventional formwork used is made of wood panel not only takes a lot of time to manufacture, but also the most damaged in the process of removing the formwork after the concrete curing is not possible to reuse, install a separate scaffold for building exterior construction There have been several problems, such as should.

Therefore, in recent years, large exterior wall formwork (commonly called gangforms) that are installed outside of buildings during concrete pouring have been developed and used essentially for new high-rise buildings, which are made of metal and can be reused repeatedly.

On the other hand, the gap between the interior and the outside form the gap between the housing to prevent the gap between the gap between the buried, the conventional gap maintenance has a significant inconvenience in assembling and dismantling the gap maintenance when the formwork is removed. In addition, there was considerable inconvenience in storage after dismantling.

In addition, after dismantling, the gap retaining zone is often separated from the formwork, and in order to solve this problem, there was considerable inconvenience such as drilling a hole in one side of the support and inserting a wire into the hole to hang it on a vertical support bar.

In addition, in the prior art, the cone nut and the fastening bolt were also used for welding, but in winter, the welding part was weakened and broken due to the material deformation of the welded part. In addition, a rubber ring is fitted to the cone to be fitted to the outer formwork for the airtightness to prevent the concrete from leaking, the width of the vertical support bar attached to the formwork does not have a constant size so that the rubber ring is fitted tightly. As a result, the effect of putting the rubber ring is not shown at all. In addition, when the concrete is poured and the simple retaining zone is slightly pushed outwards, the support brackets fitted to the fastening bolts become loose, causing various problems, such as a phenomenon of being lost in place.

On the other hand, various formwork spacing has been devised to solve the problems of the conventional formwork spacing.

As an example, a gap spacing for dies has been devised, patent registration No. 446023, which is formed by the inner bolt and the outer thread formed on the end of the tie bolt and the end of the left-side thread formed in the claims In the center, a right nut is provided with a fastening bolt, and a fixing nut is screwed to the right thread of the fastening bolt, and is interposed between the bracket and the support and the bracket fixed to the inner surface of the vertical support bar of the outer die.
