Description

{LONG AND BROAD LIGHTWEIGHT PANEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight long-width wide panel and a lightweight long-width wide panel having a structure that can be used for ceiling finishing, interior and exterior walls, and the like.

For the interior and exterior of the structure, panels made of various materials and structures are used, but most of the panels are constructed to have a short or narrow structure due to self-weight deflection and to be attached with a mosaic structure to a frame that is already constructed.

Interior and exterior decoration or ceiling finishing panels of a facility requiring decorative functions such as airports and hotels, such as ceilings and high-grade residential facilities, can be made as long and wide as possible to reduce seams and maintain continuity, The long axis or the wide panel is mainly used instead of the short axis narrow width panel in these structures and the long axis and the wide width panel are more preferable. However, in this case, the influence of deflection and twisting due to the self weight becomes relatively large, Or hangers are heavy, the weight of the hanger is large. Therefore, if the weight is not very lightweight, the configuration is difficult and various attempts have been made to reduce the weight.

Conventionally, the lightweight structure used in these panels is formed by forming a continuous bead in the longitudinal direction or by making a box-like shape composed of upper and lower plates and rims, and then attaching a reinforcing material between the upper and lower plates. However, such a structure can only be produced in a factory equipped with a complex facility in the manufacturing process, and the weight of the reinforcing material is increased as the reinforcing material increases the weight. In consideration of the transportation to the site after the manufacturing, It is difficult to form a panel having a length equal to or longer than the length of the panel.

It is an object of the present invention to provide a structure which is safer against bending, width and diagonal direction with respect to the longitudinal direction, and which can be reinforced as a self-supporting plate without using a separate reinforcing member,

In addition, the present invention can be manufactured in the field, if necessary, so that a panel having a length of 10M or more can be used without restriction on transportation, so that it can be used as an interior / exterior finishing panel or ceiling panel of a large scale structure, It is aimed to be able to utilize it as interior and exterior furnishing of high-class residential facilities.

A lightweight long-width wide panel according to the present invention is a structure in which a "? "Type front plate and a rear plate are coupled to each other with a predetermined space therebetween. In this state, the rear plate is continuously inserted in the overlapping inner sides of the front plate, A curling portion formed; Self-reinforcing elements that are spaced apart from each other around the front surface of the front plate or the rear plate and symmetrically formed with a cutting surface, the cutting surface is bent so as to face the other plate, and the ends thereof are integrally attached to the other plate And the engagement of the front plate and the rear plate is continuously performed.

Further, the self-reinforcing elements are formed on both the front plate and the rear plate so that the center planes of the respective cutting planes face each other, and the respective cutting planes cross each other.

Further, the self-reinforcing element is disposed such that the extension line of the end line of each support part constituting the self-reinforcing element and the extension line of the end line of the neighboring support part are engaged with each other in the width direction.

The present invention can secure the rigidity required for long-axis and wide-width construction by a box structure with high rigidity, a side curling structure extending therefrom and a space reinforcing effect by self-reinforcing elements using a thin metal plate, It is formed as a self-material without using a material, so that it is possible to carry out a durability and high-weight structure.

Further, since the panel can be manufactured by the continuous process and each process can be easily implemented in the field, it is possible to manufacture and install the superfine shafts on-site, and the panel suitable for the purpose of the structure can be easily Can be provided.

The present invention is characterized by comprising a front plate and a rear plate, each of which is formed by continuously bending both sides of a thin metal plate and formed in a " C "shape, wherein the rear plate is overlapped with the inside of the front plate, The cutting face is formed to be symmetrically spaced apart from each other around one face of the front plate or the rear plate, and the cutting face is bent toward the other plate and the ends thereof are integrally attached to the other plate A lightweight long-width wide panel having a structure in which a self-reinforcing element having a structure is arranged in an axial and width direction on a spaced-apart space between a front plate and a rear plate.

The cutting face for constructing the self-reinforcing element is a face formed by partially cutting the front face plate or the rear face plate in the form of ⊂ or ⊃ (or similar shape) in the symmetrical portion thereof, and the axial direction bending applied to the panel, The torsional stress is applied to the torsional stress, and the thickness of the front and rear plates is taken into consideration. The clearance is formed at appropriate intervals to maintain the required rigidity. The forming direction of the cutting surface is evenly distributed in the forward and backward directions, So that the required rigidity can be secured.

In the panel structure, the front plate itself can constitute a finished surface, and a decorative material of various materials can be attached and formed. In the case where the front plate constitutes a finished surface, When the decorative member is attached, it can be formed on both sides.

The cutting surface formed above may be attached to another plate with an inclination in a space defined by the front and rear face plates, thereby increasing the resistance to bending.

When the cutting surfaces for the self-reinforcing elements are formed on both plates, the central surfaces of the cutting surfaces face each other and the cutting surfaces cross each other. By doing so, the cutting surfaces of the front and rear surface plates are rotated about the center surface, So that it is possible to maintain a rigid rigidity with respect to warpage of up, down, left, and right.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view of a lightweight long-width wide panel according to the present invention, and FIG. As shown therein, the present invention has a structure in which the front plate 10 and the back plate 20 are continuously joined by the self-reinforcing element 40 formed between the curled portion 30 and the spaced space on both sides.

The front plate and the rear plate are made of a thin metal plate having workability such as an iron plate, a stainless steel plate, and an aluminum plate. Both side faces 11 and 21 are bent at right angles to have a "C" shaped cross section as a whole.

The width of the rear plate is formed so as to match the inner width of the front plate and is superimposed on the rear surface of the front plate. A constant space is formed between the front and rear plates. In a state where the rear plate is inserted into the front plate, The respective side heights are determined so that the ends of the respective side faces coincide with each other.

The front plate and the rear plate are integrally joined by the curling portion 30 and the self-reinforcing element 40, respectively.

The curling portion 30 is formed by curling both side edge lines of the front and rear face plates, and the curling portion is continuously formed in the axial direction, thereby increasing the moment of inertia of the panel and exhibiting high resistance strength against deflection in the axial direction When used as ceiling material, it is used to fix clips when used as hangers or inner and outer wall materials.

The curled portion may be mechanically and continuously formed while drawing the panel in the axial direction.

The self-reinforcing element 40 may be formed in various shapes depending on the shape of the cutting surface, such as an element attached to the opposite plate so as to support a certain pressure by cutting a part of the front plate or the rear plate.

3, a virtual square 24a is formed at a desired position on the front plate or the rear plate, and the left and right or upper and lower opposite sides of the virtual square are cut into the ⊂ type and the ⊃ type, respectively, as the reference line 24b A supporting portion 24d which forms a rectangular cutting surface 24c separated from each plate and has a cutting surface bent at an angle of about 45 degrees with respect to the reference line as an axis and a mounting portion 24d which is bent backward in parallel with the front plate or the rear plate 24e and then attaching the attachment portion 24e to the base plate.

In the above embodiment, the groove 24f formed after bending the cutting surface has a function of facilitating the entry of the electrode or the pressing member when the attachment portion 24e is attached to the base plate, and the cutting- And can be continuously performed at the same time as the process.

The self-reinforcing element can be formed in various shapes within a range that does not affect the withstand pressure strength of the support portion, and the arrangement form can be also variously configured.

Fig. 4 is a structure in which the self-reinforcing elements are formed together on the front and rear face plates and the self-reinforcing elements formed on the front and rear face plates cross each other. With this configuration, each of self-reinforcing elements becomes a trapezoidal structure with high rigidity, It can exhibit uniform resistance strength in vertical, horizontal, and lateral directions around the self-reinforcing element without increasing the weight, so that it has a high resistance to bending and twisting in the width direction as well as axial deflection.

Figure 5 shows a preferred arrangement of the self-reinforcing elements, wherein the thickness, spacing distance, lateral length of the upper and lower metal plates, and the spacing or arrangement of the self-reinforcing elements, etc. are dependent on the size of the stress exerted by the panel But as shown, the end lines of each support are interlocked with the end lines and axes of the neighboring supports and have a higher resistance to deformation.

FIG. 6 illustrates a manufacturing process of a panel according to the present invention. The metal plate 200 supplied in the form of a roll 100 is inserted into the upper and lower plates, respectively, and the punching and bending process 300- Bending process 400 - Curling process 500 - Self-reinforcing element attaching process 600 - The post-process 700 can be continuously performed to produce panels of required specifications.

Since each of the processes described above can be continuously performed at each step, it is theoretically possible to manufacture a long-width wide panel within the range of the length and width of a metal plate provided as a roll, and each process can be directly performed at the installation site, It is not limited by the length of the panel according to the present invention.
