Abstract: A fire resistant structure includes a bottom plate and a cover plate connected together, a heat insulation layer between the bottom plate and the cover plate, wherein the bottom plate includes a fire prevention opening, the fire prevention opening having a fire prevention opening cover nut, wherein one side of the fire prevention opening near the heat insulation layer is provided with a fire prevention opening filter, the fire prevention opening filter connected to the bottom plate. A fire arrester is provided on the cover plate, the fire arrester includes a fire arrester shell, an accommodating cavity provided therein, a fire blocking core in the accommodating cavity, and a connection portion extending from one end of the fire arrester shell, wherein a plurality of connection holes are provided on the connection portion. An end face of the fire blocking core is flush with an end face of the connection portion.

Abstract: A retention system is disclosed and includes a planar surface having first and second opposing sides. The planar surface has an array of spaced through holes defining a plurality of rows of through holes and a plurality of columns of through holes. The planar surface also has an array of spaced protrusions extending from the first side of the planar surface and defining a plurality of rows of protrusions and a plurality of columns of protrusions. Each row of protrusions is disposed between two adjacent rows of the through holes and each protrusion includes a through slot oriented in a column direction of the protrusion. An organizing set is further disclosed that includes the retention system and an attachment accessory configured to be selectively coupled to the planar surface of the retention system. A method of making the retention system is also disclosed.
