Prefabricated Columns {Prefabricated post}

The present invention relates to a prefabricated column, and in particular, a structural material for the formation of the pillar is required in a state in which a plurality of units, that is, a single inner unit and a plurality of outer units are molded in advance by injection molding or extrusion molding, or the like. By assembling according to the present invention relates to a prefabricated column that can be used to assemble the columns having a variety of diameters and appearance.

There may be various advantages when prefabricating a column.

In particular, the diameter of the column required by the consumer is inevitably varied, and in most cases, the column has been manufactured directly by the pillar of the specification required by the consumer.

The material of the pillars is also varied, and concrete pillars made by pouring concrete into formwork having internal spaces in the form of pillars, and pillars made of metal tubes and woods are commercially available.

On the other hand, it is also possible to make a pillar made of synthetic wood, it is also possible to make a product, especially a pillar by molding a composite resin of synthetic resin containing wood powder in a certain shape.

However, in order to make a column using metal, synthetic resin, or composite resin, a mold for forming the pillar is required, and when the specifications of the pillar are different, the mold for forming such pillars also needs to be changed. Manufacturing is not economical, there are disadvantages such as low productivity.

Therefore, a prefabricated column which is separately molded into several units and then assembled into a single column shape as needed may be preferable in terms of productivity or economics.

In connection with these prefabricated columns, the prior art describes several types of prefabricated columns.

Republic of Korea Utility Model Publication No. 2008-2620 discloses a multi-purpose pillar, where the multi-purpose pillar is made of a large number of pieces of light parts when making a large, sturdy column in the construction heavy equipment The multi-purpose pillar has conduit passages, and also has a feature of making pillars and walls while embedding conduits through which conduits flow. However, the multi-purpose pillar does not provide a configuration that can be assembled by arbitrarily adjusting the diameter of the pillar itself, and also the outer shape of the pillar itself is limited to provide a prefabricated column having a desired shape, such as square or hexagon.

In addition, the Republic of Korea Utility Model Registration No. 20-0406229 discloses an assembly block, the assembly block has the characteristics that can be assembled to constitute a toy or a storage box. However, this assembly block also does not provide a configuration that can be assembled by arbitrarily adjusting the diameter of the column itself, and also the shape of the column itself is limited, it does not provide a prefabricated column having the desired shape, such as square or hexagon.

Prefabricated column for achieving the object of the present invention, the inner unit is formed so that the protrusions and recesses for coupling with other inner unit or outer unit is extended in the vertical direction with respect to the longitudinal direction of the inner unit; And an outer unit formed in the main unit and the protrusion for coupling with the inner unit and the outer unit to extend in a vertical direction with respect to the longitudinal direction of the outer unit. Units are characterized in that it is made to form a single column.

The pillar may be formed by coupling a plurality of external units to the central core using one internal unit as the central core.

The pillar may be formed by combining a plurality of external units in the central core, wherein the internal units are formed by combining a plurality of internal units radially around one internal unit as a center core.

The outer units may further include an outer plane portion for allowing the pillar formed by assembly to have a polygonal shape.

The inner unit and the outer unit may further include a reinforcing wall extending in the longitudinal direction of the unit therein.

The pillar formed by the assembly of the inner unit and the outer unit may have a polygonal shape.

Therefore, in the present invention, the structural material for forming the pillar is assembled into a plurality of units, that is, one type of internal unit and a plurality of external units, as required, in a state of being molded by injection molding or extrusion molding in advance in various diameters. There is an effect of providing a prefabricated column to be used to assemble the columns having a.
