How to change the width of an aluminum panel for construction

The present invention relates to an aluminum panel used as a formwork for building construction, and more particularly, an aluminum panel for construction that is re-formed into a panel having a width changed to a specific dimension required at an individual construction site using an aluminum panel in use. It relates to a method for changing the width of a , and an aluminum panel re-formed by the method.

In general, in the construction of a building such as a building or apartment, a formwork is installed around the wall and the column until the concrete is cured by pouring the concrete slurry to erect the walls, floors and columns of the building.

Since a significant load and lateral pressure by the poured concrete act on the formwork, a high-strength material capable of withstanding such a load is required. As a conventional building formwork, so-called Euroform made of iron has been mainly used. The euroform has a configuration in which an outer frame welded along the outer periphery of the plate body on the rear surface of a square plate body in direct contact with concrete and a reinforcement frame crossing the frame are integrally formed.

On the other hand, in recent years, aluminum panels have been developed and used, which have relatively advantageous formability, handling properties, and recyclability, by replacing the iron Euroform. This is expanding rapidly. The initial aluminum panel had the same structure as the Euroform, and only the material was changed, that is, each frame consisting of a reinforcing frame and an outer frame was separately provided on the rear surface of a rectangular aluminum plate body, and the two members were integrated by welding. .

However, in the aluminum panel for construction used these days, a side frame perpendicular to the flat body along both edges of the flat body is extruded into a single body, not a simple flat body. The upper and lower frames are formed at the bottom and upper and lower frames, and the reinforcement frame is fixed in many places between the upper and lower frames by welding, etc. It is manufactured by welding the upper and lower frames and the reinforcing frame after welding the ends of the flat parts of the two members together. As such, in the case of a panel in which the side frame is integrally extruded with the flat body, the supporting strength of the side frame is significantly improved compared to the case where the side frame is formed by welding on both sides of the rear surface of the plate body made of the conventional simple flat body. In addition, it is advantageous in terms of panel productivity.

On the other hand, the aluminum panel for building formwork mainly consists of two types: a wall panel used for walls and columns and a deck panel used for slab construction. It changes in increments of 50mm up to 600mm and takes on a standard long rectangular shape with heights of 2300mm and 2450mm, and deck panels are also manufactured and shipped in standardized sizes such as 600mm x 1200mm.

However, since the overall length (width) of the wall at the building construction site is not constant, it frequently occurs that a wall form cannot be formed only with the standardized panel. A wall panel having a corresponding width must be manufactured separately, but as a panel producer operating an extrusion facility suitable for mass production of standardized panels, it is necessary to newly manufacture a wall panel with a specific non-standard width. There is a problem in that it is unavoidable to bear the additional manufacturing cost due to the inconvenience of the process and the new manufacturing of the dice.

Accordingly, there has been an attempt to manufacture and use a wall panel having a width suitable for the leftover wall using an existing standardized wall panel, particularly a panel used at least once. The above attempt is a method of cutting a certain width along the longitudinal direction of the existing standard wall panel to make it the required width, and then fixing the side frame through welding to the cut longitudinal side part, in this way In the case of manufactured or recycled aluminum panels, since the bonding strength or support strength of the side frame part attached by welding is low, the problem of bursting without being able to withstand the load or lateral pressure applied by the concrete during actual use occurs, and it cannot be put to practical use. there is.

On the other hand, as a method of regenerating a ready-made Euroform in which a wooden plywood is combined with an iron frame to a specific width required or to have two types of reduced width, after removing the wooden plate body from the frame, the longitudinal direction from a certain point in the width direction of the frame It is cut and divided into two parts, and each side frame is welded to the cut surface to form a frame with a reduced width or an intended width, and then the wood board cut to the size of each frame is combined to complete it. Euroform regeneration methods are known. However, the Euroform regeneration method cannot be applied to the aluminum foam regeneration method produced through extrusion molding of the same material because Euroform is made of a combination of heterogeneous materials such as an iron frame and plywood.

The aluminum panel provided in the first step of the method of the present invention is a panel produced with existing standardized dimensions, and any panel that has been used or has not been used may be used. The standardized dimensions are not strictly managed, but are determined in consideration of the general floor heights that have been applied in buildings for the convenience of mass production by panel producers, and do not have any special meaning or binding force.

Next, in the step of cutting off both sides of the flat panel body in a small way, the selection of the cut area is an area that matches the width of the leftovers required at the building construction site, and in more detail, the two remaining cut widths are Each of the side frames for reproduction is combined to become a point at which the width of the reconstructed panel coincides with the width of the scrap.

At this time, the width of the remaining cut width portion is suitable to ensure reliable fixation of the side frame for reproduction by securing a sufficient welding area between the ribs of the side frame for reproduction fixed by welding and the upper and lower frames and the reinforcing frame. It is desirable to ensure that the size is secured. When the flat body is cut or polished to a small extent, the surfaces of the upper and lower frames and the reinforcing frame that have been joined through welding on the bottom surface are exposed as they are while maintaining their original shape without as much damage as possible. It is advantageous in the subsequent welding with the ribs of the side frame for regeneration.

Next, when the upper and lower frames and the reinforcing frame are cut along the outer cut line of the cut width of the flat body, the outer ends of the upper and lower frames and the reinforcing frame of the cut width are outside the panel body by the length of the cut width. It is exposed in a protruding state.
