Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a slab-

More particularly, the present invention relates to a device for dismantling a slab from a slab, and more particularly, to a slab former capable of easily separating a slab from a slab and separating the slab from a slab, The present invention relates to a dissolving apparatus for molten copper.

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 tongue supporting the slab form includes a fixing bar having a hollow shape and having a ground contact supporting piece at its lower end and a threaded portion formed on the outer circumferential surface at an upper end thereof. The fixing bar is coupled to the threaded portion, 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 case of a tall slab, the slab should be supported during the curing time in the installed state, so that the load continues to be applied. After that, the supporting handle can be separated by rotating the supporting handle in the disassembling process. 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 down the concrete and accumulates on the supporting handle, the detachment or supporting handle of the locking pin can not be rotated, and the concrete must be detached after being damaged.

In order to solve the above-mentioned problems, a number of structures have been proposed in which a worker easily releases a tile supporting a slab formwork.

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.

A support device for a slab formwork is disclosed in Korean Patent No. 10-1514395, which comprises a main frame installed horizontally to support a slab formwork, a bracket mounted on the main frame, A link provided on the connection frame, a guide link selectively mounted on one of the main frame and the link, a guide link supporting the bracket vertically down when the slab form is lowered for dismantling, and a support And the link is assembled to the connection frame, the bracket is assembled to the main frame, the guide link is assembled to the bracket, and the height of the support is adjusted to the height of the slab in the field, so that installation and disassembly of the slab formwork Can be performed in a short time.

However, in the case of the above-described technology, there are problems that assembly is inconvenient because of a large number of parts, and addition of costs due to an increase in parts and reinstallation after installation are difficult.
