A splicing metal plate includes at least one pair of an elongated first and second connecting plate, the elongated first connecting plate having a side edge that extends downwardly vertically with an accommodating portion having an opening, the elongated second connecting plate having a side edge that extends downwardly vertically with an embedded portion, and the accommodating portion of the first connecting plate is embedded within the embedded portion of the second connecting plate. A front-end cover connected to a front-end of the first and second connecting plates along a length direction. A rear-end cover connected to a rear-end of the first and second connecting plates along the length direction. A supporting portion for the front-end and rear-end covers disposed at bottom portions of the first and second connecting plates.

A spliced metal plate comprises multiple strip-shaped splicing blocks (10), a front end cover (30) and a rear end cover (50). The edge area of the splicing block (10) extends vertically downward and is provided with a containing part (12) having an opening (122). The edge area of the adjoining splicing block (10) extends vertically downward and is provided with an embedding part (14). The containing part (12) and the embedding part (14) are attached with each other, with the end of the embedding part (14) stretching into the containing part (12) through the opening (122) and snapping into the containing part (12). The front end cover (30) and the rear end cover (50) are separately connected to the front end and the rear end of the splicing blocks (10) along the longitudinal direction thereof. The front end cover (30), the rear end cover (50) and the multipe splicing blocks (10) together form an open-bottomed groove structure. The spliced metal plate can fully utilize scraps and has a strong bearing capacity.

The present invention provides a method for packing a mattress spring bed: A. overlaying at least two mattress spring beds onto each other to form a mattress spring bed stack, the top side and the bottom side of the mattress spring bed stack are a mattress frame or a rigid support frame; B. placing the mattress spring bed stack into a sealing bag, then vacuuming the sealing bag, resulting in the springs of the spring beds being compressed; C. binding the mattress spring bed stack by strap. The mattress spring bed stack has a small volume, thus reducing the occupied space, increasing the transportation efficiency, and effectively reducing manufacture cost. In addition, the top side and the bottom side of the spring bed stack are respectively a mattress frame or a rigid supporting frame, therefore, the strap can more effectively bind the mattress spring bed stack, preventing deformation of the mattress spring bed stack. Furthermore, as the mattress spring bed stack is sealed by a sealing bag and bond by strap, when disassembling a mattress spring bed stack, after the strap is cut, the sealing bag causes the springs to release slowly, without the help of a machine, thus effectively providing personal safety.
