Description

Prefabricated aluminum formwork panel

The present invention relates to a prefabricated aluminum formwork panel, and more particularly, to a prefabricated aluminum formwork panel capable of assembling a divided and constructed panel easily and firmly to produce a form having a width equal to or greater than the limit of the extrusion forming of the extruder.

Building walls such as apartments, buildings, and general houses are formed by using a form to form a basic shape and then pouring and curing concrete. Typically, formwork is a construction used to hold concrete in a certain shape and dimensions, to prevent leakage of moisture required for its hardening, and to prevent concrete from being exposed to external impacts until the concrete is cured. The work of this form is very important to the concrete construction process and result, and it affects the finishing work too much, so it puts a great deal of effort on the formwork construction.

Such a form is usually divided into a Euroform formed by joining plywood to the front surface of a steel frame and a high-grade aluminum foam formed of an aluminum material.

The conventional Eurofoam can be removed and reused after the construction, but since it is heavy due to the weight of the frame made of thick plywood and steel, it is difficult for the operator to handle by himself, so that the Eurofoam can not be manufactured in a small size. There is a problem to follow.

On the other hand, Korean Patent Laid-Open Publication No. 10-1998-0009704 entitled " Aluminum Euroform (Concrete Form) and its Production Method " is an aluminum (Al) material in a conventional extruder, A first step of extrusion molding the main plate so as to form a plurality of reinforcing projections integrally in the longitudinal direction, and a step of forming a connection hole by processing the side surface of the main plate extruded in the first step of the extrusion molding step A second step of processing the reinforcement frame at both ends so that the reinforcement frame can be installed at both ends of the main plate; And a reinforcing tape bonding process in which the reinforcement frame is integrally welded.

However, in the conventional aluminum foam, since the joining portions of the main plate and the reinforcement frame have a complicated shape in the process of welding the reinforcement frame to the both end portions of the main plate having the side surface and the reinforcing projection formed together, There is a problem that it is difficult to weld along the outline line, and a large number of defect rates are generated in the welding process.

In addition, since aluminum tends to cause holes in the plate during the welding process, the thickness of the aluminum must be thicker than necessary, which increases the load of the die and the unit cost of production.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a prefabricated aluminum formwork panel capable of assembling a divided panel in a simple and robust manner to produce a form having a width equal to or greater than the limit of the extrusion limit of the extruder have.

According to the present invention, the above objects can be accomplished by providing a finishing panel for forming a finishing surface of a concrete curing space, a first flange portion projecting from both sides of the rear surface of the finishing panel in a direction intersecting the flat surface, A reinforcing bar disposed between the first flange portions provided on both sides of the finishing panel and provided with through holes in the axial direction; And a fixing bar inserted into the through hole of the reinforcement bar and the first insertion hole of the first flange portion.

Preferably, the reinforcing bars are provided with supporting protrusions, which are in contact with the finishing panel, on the side of the reinforcing bar facing the finishing panel.

It is preferable that the reinforcing rib further comprises a reinforcing rib projecting in parallel with the first flange at the rear center of the finishing panel.

It is preferable that a second insertion hole is formed through the reinforcing rib at a position corresponding to the first insertion hole.

It is preferable that the reinforcing bars are disposed on both sides of the reinforcing ribs.

The main frame may be divided into a first panel and a second panel having a first flange portion formed at one side thereof and a reinforcing rib formed at the other side thereof.

According to the present invention, there is provided a prefabricated aluminum die panel capable of assembling a divided and constructed panel easily and firmly to produce a die having a width equal to or larger than the limit of the extrusion limit of the extruder.

The first flange 112 and the reinforcing rib 114, A first insertion hole 113 and a second insertion hole 115 through which the fixing bar 130 passes are formed.

The reinforcing bar 120 is disposed between the first insertion hole 113 of the first flange portion 112 and the second insertion hole 115 of the reinforcing rib 114, A through hole 121 is formed in the axial direction and a support protrusion 122 is formed on one side of the through hole 121 to contact the rear surface of the finishing panel 111. The axial length of the reinforcing bar 120 is set to a length such that one end of the reinforcing bar 120 is in close contact with the first flange portion 112 and the other end is in close contact with the reinforcing

rib

114, 122 is preferably set to an area capable of stably supporting the concrete pressure applied to the finishing panel 111 in a state of being in contact with the finishing panel 111.

The fixing bar 130 includes a first insertion hole 113 formed in the first flange portion 112 of the first panel 110a and a second insertion hole 115 formed in the reinforcing

rib
