The invention discloses a split type easy-to-disassemble skirting line. The split type easy-to-disassemble skirting line comprises a fixed bottom plate and a decorative panel. The fixed bottom plate and the decorative panel are connected through a mortise mechanism. According to the skirting line, a single structure of a traditional skirting line is abandoned, and a split type combined structure is adopted. A wiring cavity is formed in the fixed bottom plate. The technical problems that in the prior art, an exposed wiring duct laid on a skirting line is not attractive and occupies space are solved. A noise-reduction sealing layer is arranged at the attaching position of the decoration panel and a wall body, therefore the skirting line has a silencing effect. In addition, a combination of arock wool layer and an aluminum foil layer serves as a fireproof layer, aluminum-foil paper is pasted to the outer side of the rock wool layer, the rock wool layer is prevented from absorbing water and being damped, and durability is enhanced. The split type easy-to-disassemble skirting line is compact in structure, reasonable in design, rapid and convenient to disassemble and assemble, firm andstable in structure after being installed, not prone to disengagement, good in fire resistance, high in safety and suitable for market application and popularization.
