Description

Technical Field [0001] The present invention relates to a support apparatus for slab form safety,

The present invention relates to a support disassembling apparatus for supporting a slab form, more particularly, it is possible to provide a stable installation when a slab formwork is installed, and at the same time, a support can be easily and stably separated by a worker when a form is separated from a slab, The present invention relates to a support disassembly apparatus for supporting a slab dice capable of greatly reducing the cost of dismantling as well as shortening the air.

Typically, in order to form a slab at the time of construction of a building structure, a mold is installed in a horizontal direction orthogonal to the wall surface in a state where a wall of the building is formed, and a plurality of tiles are arranged in the mold to support the mold , The concrete is put into the mold to cure the slab, and the installed mold is removed to complete the slab.

In the case of the multi-layered structure, the wall surface formwork is similarly constructed, and the formwork is installed horizontally on the upper surface of the wall surface form, then the concrete is laid on the upper surface of the wall surface formwork, and such construction is repeated to construct a multi-layered building structure.

The support for supporting the slab former may include a fixing bar having a hollow shape and having a ground contact supporting piece at the lower end thereof and a threaded portion formed on a circumference of the upper end peripheral surface thereof, A downward descent bar having a support piece for supporting the slab die at an upper end thereof, a lower end inserted through the upper side of the securing bar by sliding downwardly, and a plurality of lock holes formed at an outer side thereof at regular intervals, And a lock pin which passes through the formed hole and the lock hole of the ascending / descending bar and both ends thereof are simultaneously supported by the support handle to fix the ascending and descending bar. In installation, the support handle is rotated so that the ascending and descending bar supports the slab die When curing after a certain period of time, the support handle is rotated in the opposite direction, It is separated from the form.

However, in the case of the support, the load must be supported during the curing time in the installed state, and the load is continuously operated. Thereafter, the support handle is rotated in the disassembling process so that the separation can be performed. So that the support handle is not easily rotated.

In other words, the lock pin has to be separated from the upper side in a state in which the load is largely applied, and a load is applied to the lock pin, so that it is difficult for a worker to manually separate the lock pin.

In addition, when the concrete poured into the slab form flows on the support and accumulates on the support handle, the detachment or the support handle of the lock pin can not be rotated, and the concrete is detached after being damaged.

In order to solve the above problems, a number of structures for easily releasing a support for supporting a slab formwork have been proposed.

As an example, Korean Patent Registration No. 10-0765090 discloses a construction bucket, which is capable of supporting and disassembling a slab form by applying a hydraulic jack, and by mistaking hydraulic pressure during installation, damages the slab form And there is a problem that the hydraulic jack contracts when the inflation force acts on the curing process.

In addition, Korean Patent Registration No. 10-1514395 discloses a support device for a slab form, which is mainly intended to allow installation and disassembly of a slab formwork in a short period of time. However, There is a problem that it is inconvenient and the cost is increased due to the increase of the parts and reinstallation after installation is difficult.
