Description

  The present invention relates to a covering structure for a building that covers a wall of the building.

  Covering structures for buildings include interior structures that cover the upper partition walls, side partition walls, bottom partition bottom walls, etc. that divide spaces in houses and buildings, lower walls such as viaducts, elevated roads, and pedestrian bridges. There are coating structures for covering various wall parts, such as an exterior structure for covering, an exterior structure for covering an outer wall of a tower, an interior structure for covering an inner wall of a roadway, a soundproof wall, and a tunnel. Typical examples of this type of covering structure include the top partition wall, side partition wall, bottom partition bottom wall, etc. that divides the space of a house or building, and the ceiling, inner wall, floor of a room or hallway. Can be cited interior structures such as a ceiling structure, an inner wall structure, a floor structure, and the like.

  Many covering structures including the interior structure include a plurality of support members that are attached to a wall portion that constitutes a building at a base end portion and are arranged in parallel while maintaining a predetermined interval, and tip portions of these support members It is comprised by the several panel which is supported in parallel and covers the said wall part from the exposed surface side. In order to assemble the covering structure composed of these support members and the panel and cover the wall portion of the building, the panel is screwed and attached to the support portions on the front end side of the plurality of support members attached to the wall portion. In general, so-called screwing means is employed. Execution of the screwing means is carried out by arranging the panel so that a large number of screw holes provided in the support portion of the support member and a large number of screw holes provided in the panel face each other, and screwing through the screw holes facing each other. It is made by screwing. For this reason, it takes a lot of work to perform the screwing means.

  Since the wall portion of the building covered with the covering structure generally has a large area, a covering structure composed of a large number of support members and a large number of panels is adopted. The number of screwing points is extremely large. For this reason, the use of a large number of screws is indispensable for the execution of the screwing means, and the execution of the screwing means takes much time and time, and the work efficiency becomes extremely poor. Moreover, when the screwing means is executed, the heads of many screws used are exposed on the surface of the covering structure, and the appearance may be impaired depending on the use of the covering structure. Also become. In order to cope with such a problem, a means for blinding a large number of screw heads is required.

  In recent years, in order to solve these problems in the covering structure, a covering structure that can be assembled into a structure without using screwing means has been proposed (see Patent Document 1 and Patent Document 2).

  The above-described covering structure proposed in Patent Document 1 is proposed under the name “ceiling panel mounting structure”, and the ceiling structure configured by the ceiling panel mounting structure is supported by It consists of a plurality of bases which are members and a plurality of ceiling panels which are panels. The base has engaging pieces that are bent and extended in a wave shape from the upper side to the lower side on both side surfaces of the long base body having a U-shaped cross section upward, and the engaging pieces open downward. An engagement recess is formed. Moreover, a ceiling panel has a connection piece in the inward edge provided in the surrounding wall of the panel main body, and the connection piece is provided with protrusion. In order to assemble the ceiling structure, an attachment means is employed in which a connecting piece provided on each ceiling panel is inserted and engaged in an engagement recess of each base attached to the upper partition wall of the room. According to the attachment means, the ceiling panel can be attached to the ground with one touch, so that the number of steps required for attachment can be greatly reduced and the ceiling panel is good compared to the case of using the screwing means. There is an advantage that means for ensuring a good appearance becomes unnecessary.

  However, since the one-touch attachment means merely inserts the coupling piece on the ceiling panel side into the engagement recess on the foundation side and engages it, the ceiling panel is not firmly supported by the foundation. For this reason, if a large load is applied to the ceiling panel supported by the ground due to an earthquake or other phenomenon, or if a large load causing deflection in the horizontal direction is applied, the ceiling panel There is a high risk of falling off the groundwork.

  In addition, the covering structure proposed in the above-mentioned Patent Document 2 is proposed under the name “room”, and each support member attached to the partition wall is used for assembling the ceiling structure in the room. Mounting means for placing and supporting the ceiling panel on the support piece is employed. For this reason, in the said attachment means, compared with the case where a screwing means is employ | adopted, while being able to reduce the effort and time which installation requires significantly, the means to ensure the favorable external appearance of a ceiling panel becomes unnecessary. There is an advantage.

However, since the attachment means only places both side edges of the ceiling panel on the support pieces of both support members, the ceiling panel is not firmly supported by the support pieces. For this reason, when a load is applied in the vertical direction due to an earthquake or other phenomenon on the ceiling panel supported by each support member, or when a large load that causes deflection in the horizontal direction is applied, the ceiling panel is Like the ceiling panel supported by the above-described one-touch mounting means, there is a high possibility that the support panel will drop off.
