Description

Dongbari fastening device {SUPPORTING POST CONNECTING DEVICE}

In the field of construction and civil engineering to create a construction site by combining a yoke material structure supporting a formwork (form) used for pouring a slab with a copper bar, a Dong bar fastening device for combining the yoke material structure and Dong bar it's about

Formwork assembly used for concrete structures refers to a large panel manufactured according to the shape of the structure, or each member is assembled into one, and the concrete is poured and then cured.

In general, formwork panels are used to construct walls and ceiling beams of high-rise apartments and large civil engineering structures. Since there is a risk of the formwork assembly being separated and dismantled by the pressure generated while the concrete is cured, the yokes supporting the formwork assembly are used. used

In particular, in the construction of a multi-layered concrete structure, in order to construct a ceiling and a beam supporting the ceiling, the load of the concrete and the pressure generated while the concrete is cured are added. The risk of separation is very high compared to the formwork assembly forming other parts (walls, etc.).

Therefore, in general, in a multi-layer concrete structure, the height of the ceiling and the beam are different, so the formation height of the formwork panel is also different. A yoke material for a slab and a beam yoke material for supporting the formwork panel are used separately, and a supporter for supporting the slab yoke and the beam yoke on the floor surface, respectively, is used.

On the other hand, recently, a slab and a beam are being cast together, and this is done by a formwork (so-called "table form") for pouring a slab and a beam together.

The conventional table form is composed of a slab formwork, a beam formwork, and a reinforcing material supporting the slab formwork and the beam formwork at the bottom (each integrally configured with the slab formwork and the beam formwork), installed at a certain height.

In this regard, Patent Document No. 10-2143637 discloses that in a modular formwork, the yoke member 26 is supported on the ground through a support (support), and the yoke member 26 and the member move the yoke member 26 up and down. It is configured to be complicatedly coupled by a pin penetrating through the furnace and various members for fixing the pin. However, since the yoke material device and the copper rod correspond to a construction material having a relatively large size and weight, in the case of the above structure, considerable effort and time are required to combine the yoke material device and the copper rod or to separate the yoke material device and the copper rod. There is a problem that
