Description

Non-disband Mold assembly for fabricating the girder}

The present invention relates to a non-decomposable formwork assembly for constructing a beam, and in more detail, the overall assembly and coupling structure is simple, and at the same time, the assembly work can be conveniently performed while increasing the bonding force between the component parts pre-assembled in the factory. It relates to a non-decomposable formwork assembly for beam construction that can stably fix and minimize the number of copper bars used by stably maintaining the horizontality.

In general, in constructing a concrete building, a number of vertical columns that form the foundation while supporting the building are constructed, and a slab is constructed to form a ceiling or a floor by dividing each floor above the columns of each floor.

At this time, prior to construction of the slab, the load transmitted to the slab is distributed and distributed, while a beam, which is a horizontal girder, must be constructed to secure the support of the slab by transferring the load to the column. It can be said to be the foundation of the building.

On the other hand, in the construction of beams for distributing the load of the slab as described above, vertical columns are first constructed, and then each column is connected to each other by beams.To construct such a beam, a formwork connecting the upper part of a pair of columns on both sides is constructed. After installation, concrete was placed in the installed formwork on-site, and the formwork was separated and demolded after curing of the cast concrete.

However, the conventional method of constructing a beam using a formwork is structurally weak, so it is continuously supported by installing a large number of movable bars supporting the formwork at regular intervals under the formwork for constructing the beam until the concrete is cured. There was a problem that the work space could not be used efficiently because it had to be done.

In addition, the process of installing the formwork and demolding the formwork after curing the poured concrete takes an excessive amount of time, and the risk of safety accidents when installing and demolding the formwork located at a high place is high, as well as noise and scattering when demoulding the formwork. There was a problem that the work environment was not good because a lot of dust was generated.

(Patent Document 2) KR1186267 B1

In Patent Document 1, a lower plate formed in a rectangular shape having a length corresponding to the length of the beam structure to be constructed, has a length corresponding to the length of the lower plate, and the lower part is fixed to one side of the lower plate and erected on one side of the lower plate, and One or more first beads formed along the length direction are arranged to be spaced apart from each other along the width direction, and have a length corresponding to the length of the lower plate, and the lower end is fixed to the other side of the lower plate to the other side of the lower plate. The second side plate and the first bead and the second bead, which are erected in the longitudinal direction and arranged to be spaced apart from each other along the width direction of one or more second beads corresponding to the position of the facing first bead It provides a formwork for a beam structure including one or a plurality of side plate support members which are arranged horizontally and spaced apart from each other in the longitudinal direction, and both ends are coupled to each of the first and second beads corresponding to the horizontal direction.

However, this conventional formwork requires a plurality of side plate support members to connect them while maintaining a constant spacing between a pair of adjacent first and second side plates because the coupling force between the first and second side plates and the lower plate is weak. At the same time, both ends of the side plate support member were connected to the beads of the first and second side plate members.
