Description

Scaffolding for construction gangforms

The present invention relates to a scaffold for construction of gangform for construction, and more specifically, in the case of concrete pouring walls, etc. during new construction of high-rise apartments and multi-story buildings, the gang form (concrete form) is installed to allow continuous use by floors outside the building. It is possible to assemble and dismantle the working scaffold on the large formwork installed on the outside of the building when placing it, so that work can be done without separate scaffolding, and it is possible to use a single gang form continuously for each floor of the building. The present invention also relates to a scaffold for construction of a gang form, which has a structure that can be reassembled and used after dismantling.

In general, high-rise apartments or multi-story buildings use concrete to form the skeleton of a building.

In the concrete casting as described above, after installing the reinforcing bar structure bent to a predetermined shape by the conventional method, the formwork formed by assembling a plurality of panels on the outside of the reinforcing structure is fixed and installed, and the scaffold outside the formwork. After installation, the concrete was poured inside the formwork.

The conventional concrete pouring method as described above takes a lot of time to form the formwork because the formwork must be manufactured using a plurality of wooden panels, and the consumed panels are mostly damaged when the concrete is released, so that reuse is almost impossible. In the case of building a building, the unit cost is high and the extra work is carried out by installing a separate scaffold, which is not only inefficient but also has a high risk of safety accidents.

In order to solve the above shortcomings, many people in the relevant industry have made a lot of efforts, and in recent years, forming a formwork using a metal gang form (gang form) instead of wood panels and to form a multi-stage workbench outside the gang form. Working scaffolds have been developed that have a structure that makes them easy to work with.

Looking at the above conventional work scaffolding in detail, the plurality of horizontal support and the vertical support to the outer surface of the gangform assembly assembled by a plurality of gangform on the outside of the building integrally bonded by welding and the outside of the horizontal and vertical support The work board structure formed in multiple layers is joined together by welding. When concrete is placed on each floor of the building, the concrete is poured sequentially from the lower floor, then the gang foam assembly is demolded and installed by lifting the chain block to the upper floor. As it is poured, it is designed to be able to easily perform work on a single-floor work site without installing additional concrete, as well as placing concrete without additional gang foam.

However, the conventional working scaffold as described above is difficult to assemble because the horizontal and vertical support and the working scaffold structure are in contact with the outside of the gangform assembly by welding, and the gangform, the horizontal and vertical support and the scaffold structure are welded. Due to the difficulty of disassembling and integrally integrally, there is a problem in that continuous use is possible only for a single building, but for other buildings having different sizes, the gang foam assembly and the working scaffold structure must be separately manufactured and used.
