Prefabricated exterior panels with insulation {PREFABRICATED EXTERIOR PANELS WITH INSULATION}

The present invention relates to a prefabricated panel, and in particular, to an prefabricated exterior panel with insulation capable of providing a comfortable indoor environment by blocking harmful elements (lightning, moisture, etc.) acting on the exterior of the exterior panel constituting an exterior wall or roof. .

In general, prefabricated panels are widely used for interior and exterior of buildings such as offices, auditoriums, warehouses, and indoor gymnasiums, and are suitable for exterior walls or roof panels of buildings due to their excellent insulation properties.

In the case of an exterior panel of a wall and a roof, the prefabricated panel is inserted into an insulating material between the outer steel plate and the inner steel plate of a multi-layer structure, and is penetrated with the purlin by a fastening screw, as shown in FIG. 1. Or, as in Korean Patent Publication No. 10-2016-0025809 (published on March 9, 2016) of the prior art (patent document 0001), a'Z' shape or an L'between the inner steel plate and the outer steel plate By installing a shaped bracket, the gap between the steel plates is kept constant. However, when a lightning strike occurs due to insufficient installation of grounding facilities and lightning rods in prefabricated buildings, high-voltage electricity is energized indoors through external steel plates, brackets, and fastening screws made of metal, and the risk of causing electric accidents is very high. There was this. Or it causes condensation due to the difference between the outdoor temperature and the indoor temperature, which hinders the indoor environment such as high indoor humidity and mold, and rust occurs on the internal steel plate and steel frame of metal, which is the main cause of sharply shortening the lifespan. Worked.

For this reason, conventionally, a heat transfer blocking member is provided in the bracket installed between the inner steel plate and the outer steel plate to block external heat transfer and prevent condensation. Looking at the prior art (patent document) related to this, (Patent Document 0002) Korean Patent Publication No. 10-2016-0025809 (published on March 9, 2016), (Patent Document 0003) Korean Patent Publication No. No. 10-1655725 (announcement date September 7, 2016) has been announced, and it will be easily understood by referring to this. However, the prior art as described above has a problem in that the heat transfer blocking member provided between the first and second supports is easily damaged by an external impact force. As illustrated in FIG. 2, during the construction of the exterior panel, the heat transfer blocking member between the first and second brackets was easily damaged even with a small impact force, resulting in an increase in the loss of subsidiary materials as well as working time. This delay, workability and productivity are deteriorated, and construction costs are increased.

Korean Patent Publication No. 10-2016-0025809 (published on March 9, 2016) Korean Patent Publication No. 10-2016-0025809 (published on March 9, 2016) Korean Registered Patent Publication No. 10-1655725 (announcement date September 7, 2016)
