ANCHOR BOLT BODY FOR STEEL FORM WORK SUPPORT}

The present invention relates to an anchor bolt body for supporting a plywood wall, and more particularly, comprises a buried body embedded in a concrete and a separator separated from the embedded body, and after pouring concrete into the plywood formwork, blowing out the anchor bolt with oxygen. The present invention relates to an anchor bolt body for supporting plywood, which can reduce waste materials by eliminating the separation from the landfill body and finish the work, and improve work efficiency by eliminating the removal of the anchor bolt.

In general, in the case of a multi-story high-rise building, the reinforcing bar is laid on the ground floor, then the concrete floor is constructed, and then the formwork is built vertically or horizontally on the floor, and the building is repeated while filling the concrete.

In addition, the casting of the wall is constructed in a manner called butt wall or plywood wall, but the butt wall refers to a method of forming a wall by installing the formwork in both sides of the excavated underground space and then placing concrete therebetween.

In addition, the plywood wall refers to a method in which one side is supported by an excavated underground space and the other side is supported by formwork, and concrete is poured therebetween to form a wall. The formwork is supported by a plywood support.

1 is a side view showing an embodiment of a conventional plywood support, as shown in the conventional plywood support is a vertical support bar (3) installed adjacent to the plywood (1) construction formwork (2) and A horizontal support bar 4 orthogonal to the lower end of the vertical support bar 3 and connected in a horizontal direction, and an inclined support bar 5 having both ends thereof connected to the vertical support bar 3 and the horizontal support bar 4, respectively. It is configured to include).

At this time, the horizontal support bar (4) is fixed by the anchor bolt (6) embedded in the ground and the nut (7) coupled to the anchor bolt (6).

The conventional plywood support structure configured as described above is that the plywood is constructed by placing concrete on the formwork 2, and when curing of the poured concrete is made after the concrete is poured, supporting the formwork 2 and the formwork 2 Separate each component.

Further, the protruding end of the anchor bolt 6, which fixes the horizontal support bar 4 from the ground, is cut using a tool such as an oxygen welding machine.

However, in the case of the anchor bolt used in such a conventional plywood support, since the end is always projected to the outside of the concrete after the concrete is poured, there is a problem that the operation of cutting the end of the projecting anchor bolt is additionally generated, In order to cut and remove the protruding end of the anchor bolt, there is a problem that a worker lifts or pushes a heavy oxygen cylinder.

Furthermore, since the end of the protruding anchor bolt is cut off, the end of the cut anchor bolt is discarded as it is, which causes expensive raw materials to be discarded as it is, leading to waste of resources. In view of the shortage of raw materials, it is causing a very serious uneconomic problem.

Looking at the technology related to the conventional plywood support, the column member is coupled to one side portion of the plywood support that is registered Patent No. 10-0583774 and extending upward, the first connection bar is fixed to the upper end of the pillar member, and A length adjusting member connected to the first connecting bar and the teeth formed with the thread are interlocked with each other to adjust the length, and a second connecting bar connected to the length adjusting member at one end and the other end connected to the lower side of the plywood support.
