Description

Vibration-Absorbing Seismic Panel The present invention relates to a vibration-absorbing seismic panel, and more specifically, to a vibration-absorbing seismic panel capable of sufficiently and stably absorbing vibrations caused by an earthquake while preventing the phenomenon in which a component mounted on an exterior panel for the installation of the exterior panel is exposed to the front of the exterior panel. Exterior finishing materials are one of the key elements used to decorate and protect the exterior of a building, and the method of attaching them is an important topic in the fields of architecture and design. Accordingly, the method of attaching exterior finishing materials is also an important consideration. If we classify the historical trends of exterior finishing materials from the past to the present by material, they can be categorized into stone, tile, and metal, and the construction methods can be broadly classified into wet and dry methods. Wet construction is one of the traditional methods used since ancient architecture, involving the use of liquids or moisture, such as cement or adhesives, to attach exterior materials to a building. Wet construction, which has been used from ancient buildings through the Middle Ages and modern architecture, imposed limitations on modern architecture and design due to the limitations of technology and resources at the time. Today, dry construction methods have emerged due to advancements in exterior material technology in the construction sector and new environmental and structural requirements in modern architecture. Consequently, exterior materials made of various materials such as PC (Precast Concrete), ALC (Autoclaved Lightweight Concrete), metals, ceramics, and glass-reinforced fibers have been developed for dry construction. Among these, metal panel exterior materials are a type of curtain wall that forms the exterior finish of a building by considering three design elements of the exterior wall—such as unit panel elements, out-of-plane elements, and in-plane elements—while using attachment methods or fixed connection devices based on a transmission mechanism to ensure performance with the main structural elements of the building. In contrast to past wet construction methods, this method is utilized as an exterior finishing material construction method suitable for modern construction projects. The method of attaching exterior finishing materials significantly affects the appearance and performance of a building. Wet construction methods have disadvantages, such as construction periods being determined by installation time and weather conditions, and difficulties in guaranteeing the quality and consistency of fastening. Consequently, dry construction methods, which enable rapid construction, high productivity, and accurate attachment, have recently been gaining popularity. These two methods are important considerations in the fields of architecture and design, and this shift reflects the current trends in these fields. Meanwhile, due to the relatively low frequency of earthquakes in Korea, the seismic safety of non-structural elements has not been considered. However, concerns regarding the safety of non-structural elements have surged following the Gyeongju and Pohang earthquakes in 2016 and 2017, which caused heavy exterior materials, such as full-length windows and exterior facing bricks, to fall off commercial buildings. In the event of an earthquake, damage to non-structural elements can result in casualties and property damage, and in special cases, there is a possibility of secondary damage due to problems with the functioning of the building. In order to reflect these requirements, a “metal seismic panel for construction having a seismic composite coupling device” was filed for patent on June 24, 2020, and registered as Korean Patent No. 10-2177163 (hereinafter referred to as “prior art”) on November 4, 2020. The above prior art relates to a metal seismic-resistant panel for construction having a seismic composite coupling device that allows for easy fixing to a wall or truss by joining a coupling device, in which a fixed clip and a movable clip are joined by rivets, to an exterior panel, and by forming a composite coupling body that dampens vibrations through rivet joining between the fixed clip and the movable clip, a damping body, and a packing body, thereby preventing damage to the frame, exterior panel, and building wall; and by damping vertical vibrations of the coupling body of the fixed clip and the movable clip and dampening horizontal vibrations as the coupling body moves left and right along a slide groove, the damping effect in all directions—front, back, left, right, up, and down—is increased, thereby preventing secondary damage such as loss of life, property, and fire caused by the exterior panel detaching from the building wall due to vibrations during an earthquake or wind pressure during a typhoon.
