JP-2026075225-A - Architectural exterior materials

Abstract

[Problem] The objective is to provide building exterior materials that can be connected vertically and horizontally, and that, when connecting vertically, allow two building exterior materials located vertically to be easily positioned to connect, and that enable easy connection work. [Solution] A spandrel-type building exterior material, wherein the upper parts of the first joint plate portion 1, the second joint plate portion 2, the protruding portion 3, and the recessed portion 4 are formed as a first joint stepped plate portion 6, the second joint stepped plate portion 7, the stepped protruding portion 8, and the stepped recessed portion 9, respectively, via a step 5 that drops down to the back side, and a missing portion 10 is provided in which these three portions are connected, in a manner that includes a part of the upper part of the front surface of the stepped protruding portion 8, the upper part of the side of the stepped protruding portion 8, and the upper part of the stepped recessed portion 9.

Claims (5)

1. A rectangular building exterior material comprising: a first joint plate portion extending vertically on one side in the left-right direction; a second joint plate portion extending vertically on the other side in the left-right direction; one or more protruding ridge portions, consisting of a front portion and a side portion, extending vertically between the first and second joint plate portions; and the side portion of the protruding ridge portion on the first joint plate portion side connected to the first joint plate portion via a U-shaped or U-shaped recessed ridge receiving portion that protrudes inward and extends vertically. The upper sides of the first joint plate portion, the second joint plate portion, the protruding ridge portion, and the recessed ridge receiving portion are each formed by a step that drops down to the back side, forming a first joint step plate portion, a second joint step plate portion, a step protruding ridge portion, and a step recessed ridge receiving portion, respectively. A missing portion is provided in a state where these three portions are connected, in a manner that includes a portion of the upper part of the front portion of the step protruding ridge portion, the upper part of the side portion of the step protruding ridge portion, and the upper part of the step recessed ridge receiving portion.
2. The building exterior material according to claim 1, characterized in that the lower edges of each of the three portions constituting the missing portion are set at the same position in the vertical direction.
3. The building exterior material according to claim 1, characterized in that the step is provided in a straight line in the left-right direction, and the portion above this step is configured as an overlapping portion where other building exterior materials are superimposed.
4. The building exterior material according to claim 2, characterized in that the step is provided in a straight line in the left-right direction, and the portion above this step is configured as an overlapping portion where other building exterior materials are superimposed.
5. An exterior building material according to any one of claims 1 to 4, characterized in that the first joint plate portion, the second joint plate portion, the protruding portion, the recessed portion, the first joint stepped plate portion, the second joint stepped plate portion, the stepped protruding portion, and the stepped recessed portion are integrally molded from a single metal plate, and the step is set to a step amount equivalent to the thickness of the metal plate.

Description

This invention relates to building exterior materials used as decorative panels for the exterior, interior, ceilings, and eaves of buildings. One type of building exterior material is called a spandrel (hereinafter referred to as "spandrel material"), which has a receiving groove extending vertically on one side of the panel in the left-right direction, and an engaging piece extending vertically on the other side in the left-right direction. By fitting the engaging piece of one panel into the receiving groove of an adjacent panel in the left-right direction, panels can be successively connected in the left-right direction to form walls, ceilings, etc. Conventionally, a structure that allows connection in the vertical direction via a fitting mechanism has been proposed, as shown in Patent Document 1 (hereinafter referred to as "conventional example"). This conventional example consists of a panel body with a U-shaped cross-section, comprising a left side and a right side with an engaging portion. The left side of one panel body is connected to the engaging portion of another panel body by engaging them. Furthermore, a connecting portion is provided at the top of the panel body via a stepped portion. When the panel bodies are connected vertically using this connecting portion, no step is created at the connection point between the panel bodies, allowing for a flush connection.

A preferred embodiment of the present invention will be briefly described with reference to the drawings, illustrating the operation of the invention. In this invention, the upper parts of the first joint plate portion 1, the second joint plate portion 2, the protruding portion 3, and the recessed portion 4 are formed via a step 5 into the first joint stepped plate portion 6, the second joint stepped plate portion 7, the stepped protruding portion 8, and the stepped recessed portion 9, and when these are connected in the vertical direction, the lower parts of other building exterior materials are superimposed to form an overlapping portion 11. In this overlapping portion 11, a missing portion 10 is provided in which a part of the upper part of the front surface of the stepped protruding portion 8, the upper part of the side surface of the stepped protruding portion 8, and the upper part of the stepped recessed portion 9 are connected in a missing state. Therefore, one building exterior material located on the lower side (hereinafter referred to as "lower building exterior material P1") can be superimposed on another building exterior material located on the upper side (hereinafter referred to as "upper building exterior material P2"). When connecting the two exterior building materials, the recessed ridge receiving portion 4 on the lower end of the upper exterior building material P2 is engaged from the front into the missing portion 10 of the lower exterior building material P1. This allows the recessed ridge receiving portion 4 of the upper exterior building material P2 to overlap the lower side of the upper exterior building material P2 with the overlapping portion 11 of the lower exterior building material P1 without interfering with the stepped protruding portion 8 and stepped recessed ridge receiving portion 9 of the lower exterior building material P1. Therefore, the upper exterior building material P2 can be positioned at a predetermined connection position relative to the lower exterior building material P1. Thus, the lower exterior building material P1 and the upper exterior building material P2 can be connected by sliding the upper exterior building
