Wall panel and method for producing the same

Abstract

To provide an easy-to-work wall panel exhibiting sufficient fire resistance and heat resistance in which the amount of material of a mounting board is reduced and joint of panels is facilitated, and a method for producing it. [MEANS FOR SOLVING PROBLEMS] The wall panel (1) has an interior material (3) between a pair of mounting boards (2, 2), wherein the mounting board (2) has a portion (2a) formed by folding the opposite ends inward, and a joint metal (4) provided with a protrusion (4a) or a recess (4b) and a shoulder portion (4c) continuous to the protrusion (4a) or the recess (4b). Wall panels (1, 1) are jointed together by coupling the folded portion (2a) and the shoulder portion (4c) and fitting the protrusion (4a) to the recess (4b), and the joint metal (4) is divided substantially at the center of the protrusion (4a) or the recess (4b) into the surface side and the back side.

Description

technical field [0001] The present invention relates to a wall panel used in places such as a ship's living quarters and a manufacturing method thereof, and particularly relates to a wall panel and a manufacturing method thereof having characteristics in the joint structure of the wall panels. Background technique [0002] In the wall panels used in places such as the living quarters of ships, such as Figure 9 ~ Figure 11 Siding shown in. here, Figure 9 Wall plates shown with flat joints, Figure 10 H-joint style wall plate shown, Figure 11 Wall plate shown without joints. [0003] exist Figure 9 Among them, (A) is a horizontal cross-sectional view of the wall panels, (B) is the state before the wall panels are joined together, (C) is the state after the wall panels are joined together, and (D) is another conventional example of the flat joint method . Figure 9 The wall plate 91 shown in (A) is made up of the following parts: a surface layer plate 92 whose both en...

AI Technical Summary

Problems solved by technology

In addition, the processing of both ends of the surface layer plates 93, 102 is the main factor that prevents the surface layer plates 93, 102 from maintaining planarity.

In particular, it is difficult to control the processing accuracy, so when the ends are butted, there may be gaps in the butted part on the inner side, and there are many cases where there are problems in terms of aesthetics and fire resistance.

Moreover, when the wall panels 91 and 101 are combined, the flat joint 95 or the H-shaped joint 104 is used, so the joint itself becomes the cause of an increase in cost, and at the same time brings troubles to handling and assembly.

In addition, in Figure 9 In the wall plate 96 shown in (D), although the amount of surface steel plate used is less, the same problem as above will occur at the point of using the flat joint 95. joint, so it is difficult to maintain the accuracy of the butt joints of the wall panels 96

[0020] also, Figure 11 Although the wall panels 111, 115 shown in (A) and (D) are more Figure 10 The wall plate 101 shown in (A) uses a small amount of surface steel plate (in the case of a 600 mm wide wall plate, it is necessary to use a surface steel plate with a width of about 650 mm), but since a folded portion is formed at the end, processing is troublesome and becomes Reason for cost increase

Moreover, in addition to the problem that it is difficult to control the processing accuracy of the folded portion, there is also the problem that swelling occurs in the folded portion, and the end portion cannot become a flat plate, which hinders the appearance.

[0021] In addition, in the wall panels described in Patent Documents 2 and 3, since a flat surface plate is used, the amount of surface steel plate used is the least, but there is still a problem that the approximately convex shape or the approximately concave shape can be changed by small screws or bolts. When fixing a letter-shaped fitting, it hinders the appearance, and when fixing it with an adhesive, since the surface layer is easy to peel off at high temperature, there is a problem of insufficient fire resistance and heat resistance.
